Therefore, hereinafter, the door sensor device 10, the first window sensor device 20, and the monitor device 50 will be described in detail, and the descriptions of the service port sensor device 40 and the second window sensor device 30 will be omitted.

  As shown in FIG. 3, the first window sensor device 20 includes a battery 21, a window sensor side microcomputer (window sensor side microcomputer) 22, a window sensor side transmission circuit 23, and a window side reed switch 24.

  The battery 21 supplies power to the window sensor side microcomputer 22 and the window sensor side transmission circuit 23. The AC 100 V power source, which is a household power source, may be stepped down to supply power to the window sensor side microcomputer 22 and the window sensor side transmission circuit 23.

  The window-side reed switch 24 detects the open / closed state of the window 3 by a magnetic field of a magnet built in an operation knob of a crescent lock (not shown) of the window 3. The window-side reed switch 24 is turned on when the window 3 is closed, and is turned off when the window 3 is opened.

The window sensor side transmission circuit 23 includes a window side antenna 23a, and modulates and transmits the first ID signal input from the window sensor side microcomputer 22.
The window sensor side microcomputer 22 includes a CPU and a ROM (not shown). In the ROM, a window ID code unique to the first window sensor device 20 is recorded. The window sensor side microcomputer 22 monitors the on / off state of the window side reed switch 24, and changes the first ID signal including the window ID code and the open code from the off state to the on state when the on state is changed from the on state to the off state. In this case, the first ID signal including the window ID code and the closed code is output to the window sensor side transmission circuit 23. The window sensor side microcomputer 22 detects the on / off state of the window side reed switch 24 every time a predetermined time (for example, 2 minutes) has elapsed after transmitting the first ID signal, and includes a closed code or an open code. The first ID signal is output to the window sensor side transmission circuit 23.

  As shown in FIG. 2, a magnet 1 b is provided on the indoor side wall 1 a facing the side surface 2 b of the entrance door 2 in the vicinity of the boundary between the indoor side wall 1 a and the entrance door 2. On the other hand, a door handle 2a is provided on the indoor side of the entrance door 2, and a door sensor device 10 is provided at a position facing the magnet 1b in the vicinity of the door handle 2a. By being arranged in this way, the door sensor device 10 approaches the magnet 1b when the entrance door 2 is closed, and is separated from the magnet 1b when the entrance door 2 is opened.

  Door lock mechanisms 101 and 102 and a latch driving unit 103 are disposed on the entrance door 2. On the side surface 2 b of the entrance door 2, lock bars 101 a and 102 a that appear and disappear by the door lock mechanisms 101 and 102 are provided. Further, on the indoor side surface of the front door 2, manual lock means 101b and 102b capable of manually locking and unlocking the door locking mechanisms 101 and 102 are provided.

  Further, the door lock mechanisms 101 and 102 are mechanically connected to key cylinder portions (not shown) provided on the outdoor side of the entrance door 2, respectively, so that a mechanical key inserted into the key cylinder portion is rotated. In conjunction with this, the lock bars 101a and 102a are projected or immersed from the side surface 2b of the front door 2. Specifically, when the inserted mechanical key is rotated from the locked position to the unlocked position, the lock bars 101a and 102a are sunk from the side surface 2b of the entrance door 2, and the mechanical key is rotated from the unlocked position to the locked position. The lock bars 101a and 102a protrude from the side surface 2b of the entrance door 2. For this reason, when the mechanical key is inserted into the key cylinder and rotated from the locking position to the unlocking position, the entrance door is unlocked. On the contrary, when the mechanism key is rotated from the unlocking position to the locking position, the entrance door is locked. .

  The latch drive unit 103 is disposed between the door lock mechanism 101 and the door lock mechanism 102 in the entrance door 2.

That is, the entrance door 2 can be opened when the door handle 2a is operated in a state where the entrance door 2 is unlocked by the door lock mechanisms 101 and 102.

  As shown in FIG. 3, the door sensor device 10 includes a door-side display unit 11, an additional warning mode set switch (additional warning mode set SW) 12 as a first operation unit, and a password code input unit 13 as a second operation unit. It has. The door sensor device 10 includes a battery 14, a door sensor side microcomputer (door sensor side microcomputer) 15 as a sensor side control means, a door sensor side transmission circuit 16, and a door side reed switch 17.

  As shown in FIG. 4, the door-side display unit 11, the additional warning mode set SW 12, and the password code input unit 13 are provided on the surface of the door sensor device 10. The battery 14 is built in the door sensor device 10. In this embodiment, the door side display part 11 is comprised by LED, and additional alert mode set SW12 is comprised by the push switch. The personal identification code input unit 13 includes three push switches “A”, “B”, and “C”.

  The door side display unit 11 is turned on based on a lighting signal input from the door sensor side microcomputer 15. The personal identification code input unit 13 is connected to the door sensor side microcomputer 15, and outputs the code input by pressing the three switches to the door sensor side microcomputer 15. The battery 14 supplies power to the door sensor side microcomputer 15 and the door sensor side transmission circuit 16. Similarly to the first window sensor device 20, the AC 100 V power source, which is a household power source, may be stepped down to supply power to the door sensor side microcomputer 15 and the door sensor side transmission circuit 16.

  The door-side reed switch 17 detects the open / closed state of the entrance door 2 by a change in the magnetic field received from the magnet 1b provided in the house 1, and is turned on when the entrance door 2 is closed, and the entrance door 2 is opened. When it is in the off state.

The door sensor side transmission circuit 16 includes a door side antenna 16a, and modulates and transmits the second ID signal input from the door sensor side microcomputer 15.
The door sensor side microcomputer 15 includes a CPU, a timer, and a ROM 15a as recording means (not shown). In the ROM 15a, an entrance ID code unique to the door sensor device 10 and a password set by the user are recorded.

  A door-side reed switch 17 is connected to the door sensor-side microcomputer 15. The door sensor side microcomputer 15 monitors the on / off state of the door side reed switch 17 and changes the second ID signal including the entrance ID code and the open code from the off state to the on state when the door side reed switch 17 changes from the on state to the off state. If changed, the second ID signal including the entrance ID code and the closed code is output to the door sensor side transmission circuit 16. Further, when the door sensor side microcomputer 15 does not detect the change in the ON / OFF state of the door side reed switch 17, the door sensor side transmission circuit 16 sends the second ID signal every predetermined time (for example, 2 minutes). Output to. That is, the door sensor side microcomputer 15 outputs the second ID signal every predetermined time when there is no change in the open / closed state of the front door 2, and when the open / closed state of the front door 2 is changed, The second ID signal is output regardless of the predetermined time.

  As shown in FIG. 6A, when the additional alert mode set SW12 is pressed (point P1), the door sensor side microcomputer 15 outputs a lighting signal to the door side display unit 11 to change from the normal mode to the entrance alert mode. (Point P2). Then, the door sensor side microcomputer 15 outputs a warning set signal including the entrance ID code and the additional warning mode set code to the door sensor side transmission circuit 16 (point P3).

  When switching to the entrance warning mode, the door sensor side microcomputer 15 measures the elapsed time since the additional warning mode set SW12 is pressed by a timer, and the elapsed time after the additional warning mode set SW12 is pressed is previously stored. The output of the second ID signal is prohibited within the set period ΔT1 (15 seconds in the present embodiment). Therefore, the door sensor side microcomputer 15 does not output the second ID signal to the door sensor side transmission circuit 16 even if the front door 2 is opened and closed within the period ΔT1 immediately after switching to the entrance warning mode (point P4). Therefore, for example, when the entrance door 2 is opened and closed immediately after the additional warning mode set SW12 is pressed, such as when the housekeeper (user) goes out, the door sensor side microcomputer 15 sends the second ID signal to the door sensor side transmission circuit 16. Is not output.

  Further, when the door sensor side microcomputer 15 detects that the entrance door 2 is opened after the lapse of the period ΔT1 (point P5), the door sensor side microcomputer 15 counts the elapsed time after the entrance door 2 is opened with a timer. And the door sensor side microcomputer 15 outputs the 2nd ID signal containing an open code | cord | chord when the preset period (DELTA) T2 (this embodiment 15 seconds) passes (point P6).

  On the other hand, as shown in FIG. 6 (b), the door sensor side microcomputer 15 opens the entrance door 2 after the lapse of the period ΔT1 (point P5), and thereafter, the code (from the password input unit 13 within the period ΔT2) In this embodiment, when the operation mode of the password code input unit 13 is input, the input code is collated with the password code recorded in the ROM 15a. When the two codes match (point P10), the door sensor side microcomputer 15 switches from the entrance warning mode to the normal mode (point P11), and sends a warning reset signal including the entrance ID code and the additional warning mode reset code to the door sensor side transmission circuit. 16 (point P12).

  That is, when the entrance door 2 is opened after the lapse of the period ΔT1, the door sensor side microcomputer 15 determines that the operation is performed by the user when the collation of the password is established within the subsequent period ΔT2. And a warning reset signal is output. On the other hand, the door sensor side microcomputer 15 maintains the entrance warning mode because there is a suspicion of illegal intrusion by a third party when the password is not inputted or when the password is not verified. No warning reset signal is output.

  The monitor device 50 is installed in the vicinity of the entrance door 2 on the indoor side wall. As shown in FIG. 3, the monitor device 50 includes a power supply circuit 51, a backup battery 52, a receiving circuit 53, a monitor-side microcomputer (monitor-side microcomputer) 54 as a monitor-side control unit, and an interface unit 55.

  The power supply circuit 51 is connected to an AC 100V power source and a backup battery 52 which are household power sources. The power supply circuit 51 includes a step-down circuit (not shown), and steps down the input AC 100 V voltage to supply power to the receiving circuit 53 and the monitor-side microcomputer 54. The power supply circuit 51 supplies power from the backup battery 52 to the receiving circuit 53 and the monitor-side microcomputer 54 when a power failure is detected from a voltage drop of the AC 100V power supply.

  The receiving circuit 53 includes a receiving antenna 53a, and receives the first ID signal transmitted from the first window sensor device 20, the second ID signal transmitted from the door sensor device 10, a warning set signal, and a warning reset signal via the receiving antenna 53a. Receive. The receiving circuit 53 demodulates each received signal and outputs it to the monitor side microcomputer 54.

  As shown in FIG. 2, the interface unit 55 includes a mode changeover switch 56 as a monitor side operation means, a monitor side display unit 57, an alarm buzzer 58, and a mode display unit 59. The mode changeover switch 56, the monitor side display unit 57, the alarm buzzer 58, and the mode display unit 59 are provided on the surface of the monitor device 50, respectively. When pressed, the mode changeover switch 56 outputs an operation signal to the monitor side microcomputer 54.

  In the present embodiment, the monitor-side display unit 57 includes a plurality of LEDs. In each LED, a warning object (the entrance door 2, the window 3, etc.) indicated by each LED is displayed by a label in the vicinity thereof. Specifically, as shown in FIG. 5, the monitor-side display unit 57 in this embodiment includes an entrance warning LED 57a and a window warning LED 57b, and “entrance” is displayed below the entrance warning LED 57a and below the window warning LED 57b. Is labeled “Window 1”. Further, the entrance warning LED 57a and the window warning LED 57b emit light in red or green based on an instruction from the monitor side microcomputer 54.

  The alarm buzzer 58 sounds when an alarm signal is input from the monitor side microcomputer 54. The mode display unit 59 includes a home mode LED, a home warning mode LED, and an outing warning mode LED (all not shown). These LEDs are lit based on an instruction from the monitor side microcomputer 54.

  The monitor side microcomputer 54 includes a CPU (not shown). In the present embodiment, the monitor-side microcomputer 54 has three types of alert modes (at-home alert mode, outing alert mode, and additional alert mode). When the mode changeover switch 56 is operated, the monitor-side microcomputer 54 switches to any one of the home mode (monitoring mode), the home security mode, and the outing warning mode. Specifically, as shown in FIG. 7, when the mode changeover switch 56 is pressed in the home mode M1, the monitor side microcomputer 54 lights the home warning mode LED of the mode display unit 59 and switches to the home warning mode M2. Change. In addition, when the mode changeover switch 56 is pressed in the home warning mode M2, the monitor side microcomputer 54 turns on the going out warning mode LED of the monitor side display unit 57 and switches to the going out warning mode M3. When the mode changeover switch 56 is pressed in the outing warning mode M3, the monitor side microcomputer 54 turns on the home mode LED of the monitor side display unit 57 and switches to the home mode M1.

  Further, when the monitor-side microcomputer 54 receives a warning set signal in the home warning mode M2 or the outing warning mode M3, the monitor side microcomputer 54 switches to the additional warning mode M4. Specifically, the monitor-side microcomputer 54 switches to the additional warning mode M4 when the received signal includes an additional warning mode set code. The monitor-side microcomputer 54 blinks the home warning mode LED when the home warning mode M2 is switched to the additional warning mode M4, and goes out warning when the home warning mode M3 is switched to the additional warning mode M4. Make the mode LED blink.

  Moreover, the monitor side microcomputer 54 will switch to the mode before switching to additional warning mode M4, when a warning reset signal is received in additional warning mode M4. Specifically, when the received signal includes an additional warning mode reset code, the monitor-side microcomputer 54 switches to the home warning mode M2 or the outing warning mode M3. More specifically, as shown in FIG. 8A, when the monitor side microcomputer 54 receives the warning set signal in the home warning mode M2 and switches to the additional warning mode M4, the home side warning 54 receives the warning reset signal. Switch to mode M2. On the other hand, as shown in FIG. 8 (b), when the warning set signal is received in the going-out warning mode M3 and the mode is switched to the additional warning mode M4, the monitor-side microcomputer 54 receives the warning reset signal and then goes out. Switch to.

The monitor-side microcomputer 54 monitors whether there is an abnormality such as a person (third party) other than the user entering the house 1, and performs security control to sound an alarm if an abnormality occurs for a predetermined time. Do it every time. Hereinafter, security control performed by the monitor-side microcomputer 54 will be described with reference to the flowcharts shown in FIGS.

  First, in step 150, the monitor-side microcomputer 54 performs a monitoring process for monitoring the open / closed state of the front door 2 and the locked / unlocked state of the window 3. Specifically, when the monitor-side microcomputer 54 receives the first ID signal transmitted from the first window sensor device 20 and the second ID signal transmitted from the door sensor device 10, the monitor-side microcomputer 54 converts the open code or the closed code included in each ID signal. Based on this, the monitor side display unit 57 is operated. The monitor-side microcomputer 54 turns on the window warning LED 57b in green when the received first ID signal includes a closed code, and turns the window warning LED 57b on when the received first ID signal includes an open code. Turn on red. Further, the monitor-side microcomputer 54 lights the entrance warning LED 57a in green when the received second ID signal includes a closed code, and detects the entrance warning when the received second ID signal includes an open code. The LED 57a is lit red. That is, the monitor device 50 includes the door sensor device 10 and the door sensor device 10 in the four types of modes (the home mode M1 and the three types of warning modes M2 to M4), and the door sensor device 10 The open / closed state of the corresponding entrance door 2 is monitored, and these states are notified by the lighting colors of the window warning LED 57b and the entrance warning LED 57a of the monitor-side display unit 57.

  In step 151, the monitor side microcomputer 54 determines whether or not the value of the flag (mode FG) indicating whether or not to accept the operation of the mode changeover switch 56 is “0”. In this embodiment, when the value of the mode FG is “0”, the monitor side microcomputer 54 accepts the operation of the mode changeover switch 56 (enables the operation of the mode changeover switch 56), and the value of the mode FG is “1”. ", The operation of the mode changeover switch 56 is not accepted (the operation of the mode changeover switch 56 is invalidated). If the monitor-side microcomputer 54 determines that the value of the mode FG is “0”, the monitor-side microcomputer 54 enables the operation of the mode switch 56 and proceeds to step 152. In step 152, the monitor side microcomputer 54 determines whether or not the home mode M1 is set.

  If it is determined that the home mode M1 is set, the monitor-side microcomputer 54 proceeds to step 153 and prohibits the output of the alarm signal. That is, the monitor side microcomputer 54 does not output an alarm signal in the home mode. Therefore, in the home mode, the alarm buzzer 58 does not sound even if the front door 2 is opened or the window 3 is unlocked. When the process of step 153 is completed, the monitor-side microcomputer 54 once ends the process.

  On the other hand, if it is determined in step 152 that the home mode M1 is not set, the monitor-side microcomputer 54 proceeds to step 154 and determines whether or not the home security mode M2 is set. If it is determined that the home security mode M2 is set, in step 155, the monitor-side microcomputer 54 has received an open code, that is, whether the first ID signal or the second ID signal contains an open code. Judging. If the monitor side microcomputer 54 determines that the open code is not included in the first ID signal or the second ID signal, the monitor-side microcomputer 54 temporarily ends the process, and the open code is included in the first ID signal or the second ID signal. If it is determined, an alarm signal is output in step 156.

  Specifically, the monitor-side microcomputer 54 turns on the window warning LED 57b of the monitor-side display unit 57 in red and outputs an alarm signal to the alarm buzzer 58 when the first ID signal includes an open code. Further, when the open ID is included in the second ID signal, the monitor-side microcomputer 54 lights the entrance warning LED 57a of the monitor-side display unit 57 in red and outputs an alarm signal to the alarm buzzer 58. That is, when the entrance door 2 changes from the closed state to the open state, the entrance warning LED 57a of the monitor side display unit 57 changes from green lighting to red lighting, the alarm buzzer 58 sounds, and the window 3 changes from the closed state to the open state. Then, the window warning LED 57b of the monitor side display unit 57 changes from green lighting to red lighting, and the alarm buzzer 58 sounds.

In subsequent step 157, the monitor-side microcomputer 54 determines whether or not an alarm signal has been output over an alarm period (for example, 30 seconds). If the monitor-side microcomputer 54 determines that the alarm signal is not output over the alarm period, the monitor-side microcomputer 54 terminates the process with the alarm signal output, and determines that the alarm signal is output over the alarm period. In step 158, the output of the alarm signal is stopped and the process is temporarily terminated. The monitor-side microcomputer 54 performs the processing of step 153 when the mode changeover switch 56 is operated and the home mode M1 is switched while the alarm signal is output, that is, when the alarm buzzer 58 is sounding. Execute. In step 153, since the output of the alarm signal is prohibited, the monitor side microcomputer 54 stops the output of the alarm signal and stops the alarm buzzer 58 from sounding.

  By the way, if it is determined in step 154 that the home warning mode M2 is not set, the monitor side microcomputer 54 determines whether or not the outing warning mode M3 is set in step 159. If it is determined that the outing warning mode M3 is set, in step 160, the monitor side microcomputer 54 determines whether or not an open code has been received. If the monitor-side microcomputer 54 determines that the open code has not been received, the monitor-side microcomputer 54 temporarily terminates the process. If the monitor-side microcomputer 54 determines that the open code has been received, it outputs an alarm signal in step 161.

  In step 162, the monitor side microcomputer 54 determines whether or not the alarm period has elapsed since the alarm signal was output. If the monitor-side microcomputer 54 determines that the alarm period has not elapsed after outputting the alarm signal, the monitor-side microcomputer 54 continues to output the alarm signal without proceeding to the next step 163. For this reason, even if the mode changeover switch 56 is operated until the alarm signal is output over the alarm period, that is, until the alarm buzzer 58 sounds over the alarm period, the mode of the monitor device 50 is not switched. On the other hand, if it is determined that the alarm period has elapsed since the output of the alarm signal, the monitor-side microcomputer 54 stops the output of the alarm signal in step 163 and ends the process once.

  By the way, if it is determined in step 151 that the value of the mode FG is not “0”, or if it is determined in step 159 that it is not set to the outing warning mode M3, the monitor side microcomputer 54 performs step 164 shown in FIG. It is determined whether or not the additional alert mode M4 is set. If the monitor-side microcomputer 54 determines that the additional warning mode M4 is not set, the monitor-side microcomputer 54 terminates the process. If the monitor-side microcomputer 54 determines that the additional warning mode M4 is set, the monitor-side microcomputer 54 sets the mode FG in step 165. Set “1” to. Therefore, the operation of the mode switch 56 becomes invalid.

  In step 166, the monitor side microcomputer 54 determines whether or not a warning reset signal has been received. If the monitor-side microcomputer 54 determines that the warning reset signal has not been received, the process proceeds to step 168. If the monitor-side microcomputer 54 determines that the warning reset signal has been received, the monitor-side microcomputer 54 changes the mode FG to “mode FG”. After “0” is set, the process proceeds to step 168. That is, when the mode FG is set to “0” in step 167, the operation of the mode switch 56 becomes valid.

  In step 168, the monitor side microcomputer 54 determines whether or not an open code has been received. If the monitor-side microcomputer 54 determines that the open code is not received, the monitor-side microcomputer once terminates the process. If the monitor-side microcomputer 54 determines that the open code has been received, it outputs an alarm signal in step 169.

  In step 170, the monitor side microcomputer 54 determines whether or not the alarm period has elapsed since the alarm signal was output. If the monitor-side microcomputer 54 determines that the alarm period has not elapsed since the output of the alarm signal, the monitor-side microcomputer 54 continues to output the alarm signal without proceeding to the next step 171. On the other hand, if it is determined that the alarm period has elapsed since the alarm signal was output, the monitor-side microcomputer 54 stops the output of the alarm signal in step 171 and ends the process once.

  An example of the operation mode of the security system 100 configured as described above will be described with reference to FIG. Here, the flow of processing performed between the door sensor device 10 and the monitor device 50 will be described in detail.

<When going out>
When the mode changeover switch 56 is pressed, the monitor device 50 switches to the home warning mode M2 or the outing warning mode M3 (step 200). As described above, the monitoring device 50 can be switched to the additional warning mode M4 by switching to the home warning mode M2 or the outing warning mode M3.

  When the additional warning mode set SW12 is pressed (step 201), the door sensor device 10 counts the elapsed time after the pressing operation by a timer and outputs a warning set signal in step 202. Moreover, the door sensor apparatus 10 operates the door side display part 11 in step 203, and notifies that it switched to the entrance warning mode.

  The monitor device 50 that has received the warning set signal switches from the home warning mode M2 or the outing warning mode M3 to the additional warning mode M4 (step 204). The monitor device 50 operates the mode display unit 59 in step 205 to notify that the mode has been switched to the additional warning mode M4.

  The door sensor device 10 prohibits the output of the second ID signal when the elapsed time since the additional warning mode set SW12 is pressed is within the period ΔT1. For this reason, as shown in step 206, for example, even if the front door 2 is opened and closed within the period ΔT1, the door sensor device 10 does not transmit the second ID signal. Therefore, the user is annoyed that the alarm buzzer 58 sounds when the entrance door 2 is opened and closed by opening and closing the entrance door 2 within a period ΔT1 after pressing the additional alert mode set SW12. Is released from.

<When a third party of trespassing>
When the entrance door 2 is opened after the period ΔT1 has elapsed (step 207), the door sensor device 10 transmits a second ID signal including an open code when the period ΔT2 has elapsed since the entrance door 2 was opened (step 208). ).

  When receiving the second ID signal, the monitor device 50 sounds the alarm buzzer 58 over the alarm period (step 209). Therefore, when a third party enters the room through the entrance door 2 by cheating, the alarm buzzer 58 sounds when the period ΔT2 has elapsed since the entrance door 2 was opened. In addition, since the operation of the mode changeover switch 56 becomes invalid in the additional warning mode M4, even if the mode changeover switch 56 is pressed, the alarm buzzer 58 cannot be sounded. Therefore, it is possible to prevent a third party from operating the mode changeover switch 56 and stopping the alarm buzzer 58 from sounding.

<At home>
On the other hand, the door sensor device 10, the entrance door 2 is opened after a period ΔT1 has elapsed (step 210), the personal identification code period ΔT2 within since the front door 2 is opened is input (step 211), warning at step 211 A reset signal is transmitted (step 212).

  The monitor device 50 that has received the warning reset signal switches to the home warning mode M2 or the outing warning mode M3, which is the mode before switching to the additional warning mode M4 (step 213). In the home warning mode M2 or the outing warning mode M3, the mode of the monitor device 50 can be switched. Therefore, the user can switch to the home mode M1 by pressing the mode switch 56. Therefore, when the user returns home and opens and closes the front door 2, the alarm buzzer 58 can be prohibited or stopped by inputting a password and pressing the mode changeover switch 56.

Therefore, according to the present embodiment, the following effects can be obtained.
(1) The door sensor device 10 outputs a warning set signal when the additional warning mode set SW12 is pressed. The monitor-side microcomputer 54 that has received the warning set signal switches to the additional warning mode M4. In the additional warning mode M4, the monitor-side microcomputer 54 disables the operation of the mode changeover switch 56 and disables switching from the additional warning mode M4 to other modes such as the home warning mode M2. That is, even if the mode changeover switch 56 is pressed, it cannot be switched to the home mode M1 in which the alarm buzzer 58 is not sounded. That is, when the alarm buzzer 58 sounds, a third party cannot stop the alarm buzzer 58 from sounding. Therefore, the security level of the building can be improved.

  (2) The door sensor device 10 outputs a warning reset signal when the code input from the password code input unit 13 and the password code recorded in the ROM 15a are equal. For this reason, even if a third party who cannot know the security code enters the room from the front door 2 by cheating, the mode of the monitor device 50 cannot be switched from the additional warning mode M4 to the home mode M1. When the buzzer 58 sounds, the alarm buzzer 58 cannot be stopped. Therefore, the security level of the building can be further improved.

  (3) The door sensor device 10 outputs a warning reset signal when the code input from the password code input unit 13 and the password code recorded in the ROM 15a are equal. The monitor-side microcomputer 54 that has received the warning reset signal sets the mode FG to “0” and enables the operation of the mode changeover switch 56. The monitor-side microcomputer 54 switches to the home mode M1 when the mode change switch 56 is pressed while the mode change switch 56 is valid. As described above, the monitor-side microcomputer 54 switches from the additional warning mode M4 to the home mode M1 based on the reception of the warning reset signal output from the door sensor device 10 and the operation of the mode changeover switch 56. That is, the monitor device 50 switches from the additional warning mode M4 to the home mode M1 on condition that a complicated operation such as operating the personal identification code input unit 13 and the mode changeover switch 56 of the door sensor device 10 is performed. Therefore, a third party cannot switch the mode of the monitor device 50 to the home mode M1, and the security level of the building can be improved.

  (4) The personal identification code input unit 13 includes three push switches “A”, “B”, and “C”. The password code is set according to the operation mode of these three push switches. Therefore, it is possible to easily remember a password code for switching the additional warning mode M4 to the home warning mode M2 or the going-out warning mode M3, and it is possible to suppress a mistake in inputting the password code by the user. Therefore, the burden when using the security system can be reduced, and the convenience of the security system can be improved.

(5) In order to switch from the additional warning mode M4 to the home mode M1, the password code is input from the password code input unit 13 to switch to the home warning mode M2 or the outing warning mode M3, and the mode switch 56 is further operated. As described above, since the mode can be switched to the home mode M1 by operating the personal identification code input unit 13 and the mode changeover switch 56, a dedicated electronic key for switching to the home mode M1 is unnecessary. Therefore, the number of belongings when going out can be suppressed. Further, illegal entry into the house 1 due to theft of the electronic key can be prevented. Therefore, the convenience of the security system can be improved and the security level of the building can be improved.

  (6) The door sensor device 10 prohibits the output of the second ID signal when the elapsed time after the additional warning mode set SW12 is pressed is within the period ΔT1. For this reason, the user can go outside without sounding the alarm buzzer 58 by opening and closing the entrance door 2 within the period ΔT1 after pressing the additional warning mode set SW12. Therefore, the convenience of the security system can be improved.

  (7) The door sensor device 10 transmits the second ID signal including the open code when the entrance door 2 is opened after the lapse of the period ΔT1 and no password is input within the period ΔT2. For this reason, the monitor apparatus 50 can sound the alarm buzzer 58 reliably and can alert | report the invasion of the third party to the circumference | surroundings. Moreover, even if a third party closes the entrance door 2 when entering the house 1, if the entrance door 2 is opened even at the time of entry, the alarm buzzer 58 sounds after a period ΔT2 has elapsed since the entrance door 2 was opened. To do. Therefore, the security level of the building can be further improved.

  (8) The door sensor device 10 controls the output of the second ID signal, the warning set signal, and the warning reset signal. The monitor device 50 performs security control based on the signal transmitted from the door sensor device 10. As described above, most of the signals necessary for the security control performed by the monitor device 50 are generated in the door sensor device 10. Therefore, a conventional security system including the first window sensor device 20, the second window sensor device 30, and the monitor device 50 (corresponding to a conventional lock / unlock state monitoring device that monitors only the lock / unlock state of the window). Can be easily extended to the security system 100 including the door sensor device 10 and the service port sensor device 40. Specifically, the door sensor device 10 is disposed on the front door 2, the front door sensor device 40 is disposed on the front door 5, and processing based on the warning set signal and the warning reset signal is performed on the program of the monitor side microcomputer 54. The conventional security system can be extended to the security system 100 with only a small change such as adding a program for performing. Therefore, the conventional security system and the security system 100 can be selected according to the user's needs, and the convenience of the security system can be improved. Further, since the change of the monitor device 50 accompanying the expansion of the security system is only a small change of the program of the monitor-side microcomputer 54, the design cost and manufacturing cost of the security system 100 can be suppressed.

In addition, you may change embodiment of this invention as follows.
In the embodiment, the door sensor side microcomputer 15 that has been switched to the entrance warning mode outputs a warning reset signal when the code input from the password code input unit 13 matches the password code recorded in the ROM 15a. However, the condition for the door sensor side microcomputer 15 to output the warning reset signal is not limited to the case where the code input from the password code input unit 13 matches the password code recorded in the ROM 15a. For example, the door sensor device 10 includes a biometric authentication input unit, and the door sensor-side microcomputer 15 resets the alert when biometric information (for example, a fingerprint) input from the biometric authentication input unit matches biometric information recorded in advance in the ROM 15a. It may be changed to output a signal. In this way, the user does not need to memorize the password, so the convenience of the security system is further improved.

  -The monitoring apparatus 50 in the said embodiment switches to the additional alert mode M4, when the alert set signal is received in the home alert mode M2 or the going-out alert mode M3. However, the monitor device 50 may be changed to switch to the additional warning mode M4 even when the warning set signal is received in the home mode M1. In this way, the monitor device 50 can be switched from the home mode M1 to the additional warning mode M4 only by operating the additional warning mode set SW12 of the door sensor device 10 when going out. Therefore, the operation for switching the monitor device 50 from the home mode M1 to the additional alert mode M4 is simplified, and the convenience of the security system can be improved. In this case, the door sensor device 10 may record a set code for shifting to the entrance warning mode in the ROM 15a. The door sensor device 10 may be changed to switch to the entrance warning mode when the code input from the personal identification code input unit 13 matches the set code recorded in the ROM 15a. In this way, it is possible to prevent the monitor device 50 from switching to the additional warning mode M4 due to an operation not intended by the user (for example, a pressing operation of the additional warning mode set SW12 or the password code input unit 13 by a child). .

  In the embodiment, when the monitoring device 50 that has shifted to the additional warning mode M4 receives a warning reset signal, the monitoring apparatus 50 switches to the mode before switching to the additional warning mode M4. However, the monitor device 50 may be changed so as to select a switching destination based on the code included in the received alert reset signal. Specifically, in the ROM 15a of the door sensor side microcomputer 15, the first password for switching the monitor device 50 to the mode before switching to the additional alert mode M4 and the second code for switching the monitor device 50 to the home mode M1 are stored. A password is recorded. The door sensor device 10 is changed to transmit a warning reset signal including the entrance ID code and the first reset code when the code input from the password code input unit 13 matches the first password. Further, the door sensor device 10 is changed to transmit a warning reset signal including the entrance ID code and the second reset code when the code input from the password code input unit 13 matches the second password code.

  When the monitor device 50 is changed in this way, as shown in FIG. 12A, the monitor device 50 switches from the home warning mode M2 to the additional warning mode M4 and receives a warning reset signal including the first reset code. The mode M4 is switched to the home alert mode M2. Also, as shown in FIG. 12 (b), when switching from the outing warning mode M3 to the additional warning mode M4 and receiving a warning reset signal including the first reset code, the monitor device 50 goes out of the additional warning mode M4. Switch to mode M3. On the other hand, as shown in FIGS. 12A and 12B, when the monitoring device 50 receives a warning reset signal including the second reset code in the additional warning mode M4, the monitoring apparatus 50 switches from the additional warning mode M4 to the home mode M1. Change.

  In this way, for example, the operation for switching from the additional warning mode M4 to the home mode M1 becomes simple when returning home. Therefore, the convenience of the security system can be improved.

  In the embodiment, if the monitor-side microcomputer 54 cannot receive the first ID code or the second ID code from the door sensor device 10 or the first window sensor device 20 even after a predetermined time has elapsed, the door sensor device 10 or the first window sensor device It may be changed so that the alarm buzzer 58 is sounded as if there is an abnormality in 20. In this way, the building security level can be further improved.

  -In the said embodiment, the door sensor side microcomputer 15 measures the elapsed time after the additional warning mode set SW12 is pressed by a timer, and the elapsed time after the additional warning mode set SW12 is pressed is within the period ΔT1. If so, the output of the second ID signal is prohibited. However, even if the door sensor side microcomputer 15 is changed to output the second ID signal when the additional warning mode set SW12 is pressed to switch to the entrance warning mode or the entrance door 2 is opened. Good. That is, the period ΔT1 may not be set. In this way, since the alarm buzzer 58 sounds when the additional warning mode set SW12 is pressed to go out, the user sounds that the alarm buzzer 58 has switched to the additional warning mode M4. Can be confirmed.

  In the above-described embodiment, the personal identification code input unit 13 as the second operation unit is configured by three push switches “A”, “B”, and “C”. However, the second operation means may be a switch (for example, a push switch) disposed in a place near the entrance door 2 where it is difficult to see. In this case, the door sensor side microcomputer 15 is changed so as to switch to the entrance warning mode and transmit a warning set signal when the switch is pressed. Even if the security system 100 is configured in this way, the security of the building can be improved as compared with the conventional system.

  -In the said embodiment, the door sensor side microcomputer 15 measures the elapsed time after the additional warning mode set SW12 is pressed by a timer, and the elapsed time after the additional warning mode set SW12 is pressed is within the period ΔT1. If so, the output of the second ID signal is prohibited. However, the same processing may be performed by the monitor side microcomputer 54. Specifically, when the monitor-side microcomputer 54 receives the warning set signal, the monitor-side microcomputer 54 receives the second ID signal including the open code if the elapsed time from the reception of the warning set signal is within the period ΔT1. Alternatively, the alarm buzzer 58 may be changed so as not to sound. Even in this case, the user can go outside without sounding the alarm buzzer 58 by opening and closing the entrance door 2 within the period ΔT1 after pressing the additional warning mode set SW12.

Moreover, since the door sensor side microcomputer 15 does not need to measure the elapsed time after the additional warning mode set SW12 is pressed, the processing load is reduced.
In the above-described embodiment, the door sensor side microcomputer 15 collates the password entered from the password code input unit 13, but the present invention is not limited to this. For example, when a code is input from the personal identification code input unit 13, the door sensor side microcomputer 15 may be changed to output a second ID signal including the input code and the entrance ID code. The monitor-side microcomputer 54 may include a memory, and the password code may be recorded in the memory. The monitor-side microcomputer 54 receives the second ID signal including the input code within the period ΔT2 after recognizing that the front door 2 has been opened from the open code included in the second ID signal after the period ΔT1 has elapsed. In this case, the input code may be collated with the password code recorded in the memory. At the same time, when the two codes match, the monitor-side microcomputer 54 may be changed to switch from the additional warning mode M4 to the home warning mode M2 or the outing warning mode M3. In this way, the door sensor side microcomputer 15 does not need to collate the code input from the password code input unit 13 and the password code, so that the processing load on the door sensor side microcomputer 15 can be reduced.

  In the above embodiment, the door sensor side microcomputer 15 receives the warning reset signal within the period ΔT2 when the entrance door 2 is opened after the period ΔT1 has elapsed since switching to the entrance warning mode. When the period ΔT2 elapses, the second ID signal including the open code is output. However, when the door sensor side microcomputer 15 receives the warning reset signal within the period ΔT2, the door sensor side microcomputer 15 may be changed so as not to transmit the second ID signal including the open code even if the front door 2 is opened and closed within the period ΔT2. In this way, even if the front door 2 is opened and closed when returning home, the alarm buzzer 58 is not sounded without operating the mode changeover switch 56 of the monitor device 50 by inputting the password within the period ΔT2. be able to. Therefore, the operation for preventing the alarm buzzer 38 from sounding when returning home is simplified, and the convenience of the security system 100 can be improved.

  Further, when the monitor-side microcomputer 54 receives the warning reset signal, the monitor-side microcomputer 54 switches to a warning mode (at-home warning mode M2 or outing warning mode M3) before switching to the additional warning mode M4. That is, just operating the door sensor device 10 does not switch to the home mode M1, but keeps the alert mode. For this reason, when only the PIN code is input and the mode switch 56 is not operated, when the window 3 or the window 4 is unlocked by a third party or when the door 5 is opened. Alarm buzzer 58 sounds. For example, the window 3 or the window can be used even during the period from entering the indoor to the outside by operating the personal identification code input unit 13 of the door sensor device 10 by temporarily entering the indoor from the front door 2 to collect forgotten items. When 4 is unlocked and when the door 5 is opened, the alarm buzzer 58 can be sounded. Therefore, the security level of the building can be further improved.

Next, the technical idea that can be grasped from the embodiment will be described below.
(1) In the security system , immediately after outputting the warning set signal, the sensor device does not notify the open / closed state or the unlocked state of the opening / closing body for a predetermined period.
