Abstract

PURPOSE:To issue an alarm automatically when a condition is brought about which should cause judgement as abnormal, by emitting an abnormality signal if the judgement by a continuity judging means is such that an output signal from a human body sensing means is lasting longer than the time set previously. CONSTITUTION:If a human body sensing means A is installed in each room of a house so as the sense eventual existence of a human being, it can be judged that a certain abnormality has occurred in case a condition much different from everyday behavior lasts, for ex. a person as object of sensing remains out of motion for some long time. Accordingly, abnormality can be sensed automatically by setting appropriately the time as the reference for judgement to be placed by a continuity judging means B, and an abnormality signal E is emitted by an abnormality signal output means C. Thus, abnormality is informed.

Description

[Detailed Description of the Invention] <Industrial Application Field> This invention can be installed, for example, in an elderly person's room where the person lives alone, to automatically issue a notification signal when something abnormal occurs in the person. The present invention relates to an abnormal state detection device.

<Conventional Technology> In recent years, elderly people who live alone have been increasing their power consumption, and if that person falls down due to a sudden illness, there is a high possibility that the person will not notice it late because there is no one around, and it will lead to serious problems. For this reason, efforts have been made to install an easy-to-operate alarm telephone in the person's home or to carry a small transmitter with them at all times, so that they can notify a predetermined number of parties in the event of an abnormality. It is being

<Problem to be solved by the invention> Since the above-mentioned notification in abnormal situations is based on the premise that the person in question operates a switch, etc., if the user suddenly becomes unable to operate the switch, it is impossible to make a call and the notification cannot be made. can't do it.

The present invention has been made with the aim of providing a device that automatically issues a notification when a situation that is determined to be abnormal occurs, paying attention to such an abnormality.

<Means for Solving the Problems> In order to achieve the above object, the abnormal state detection device of the present invention includes a person detection means for detecting the presence of a person and outputting a detection signal, and a person detection means for detecting the presence of a person and outputting a detection signal. a continuation determination means for determining whether or not a detection signal from the person detection means continues for longer than a preset time; and an abnormality signal output means that outputs an abnormality signal when the determination is made.

The first @ is a diagram showing the configuration of the present invention, where A is a person detection means, B is a continuation determination means, C is an abnormal signal output means, D is a detection signal, and E is an abnormal signal.

<Function> For example, if the person detection means A is installed in each room of a house to detect the presence of a person, the detected person will not move for a long time and will be detected continuously. If a state that is significantly different from the behavior continues, it can be determined that some abnormality has occurred. Therefore, by appropriately setting the time that is the criterion for the determination by the continuation determining means B, an abnormality is automatically detected, and the abnormality signal E is output from the abnormality signal output means C to notify the abnormality.

<Example> Next, an example of the illustrated elderly person abnormality monitoring system will be described.

FIG. 2 is a block diagram of this system, in which 1 is a control device, 2 is a control circuit section, 3 is a receiver, 4 is a confirmation message output circuit, and 5 is a telephone I/F. The control circuit unit 2 includes, for example, a ROM 21 that stores control programs, etc., a CPU 22 that performs various calculations, and a RAM 23 that is used for calculations.
etc., but this does not necessarily have to be a microcomputer, and -
It can also be configured with discrete circuits similar to boat fishing.

6 is a portable notification transmitter, 7 is an indoor notification switch, 8 is an outing detection sensor, and 9 is a newspaper receiver sensor. The portable notification transmitter 6 is configured to transmit a predetermined radio wave to the receiver 3 by operating the switch at the user's will, and is configured to be able to notify abnormalities wirelessly from indoors and outdoors. At least one unit 7 is installed at a suitable location in the house so that abnormalities can be reported to the control device 1 by wire when operated by the person himself/herself. Also, the missing item detection sensor 8 sends a signal to the control device 1 when the entrance lock is locked.
Control circuit unit 2 determines whether the product is out of stock or at home depending on the procedure at that time.
The sensor 9 of the newspaper receiver is configured to send a detection signal of the presence or absence of a newspaper to the control device 1. If the newspaper is not picked up, which is different from the daily behavior pattern, the control circuit section 2 detects an abnormality. It is configured so that it can be determined.

10 is an indoor activity detection sensor, 11 is a bath activity detection sensor, and 12 is a toilet activity detection sensor. These sensors are person detection means in the present invention, and are capable of detecting the presence of a person using, for example, ultrasonic waves or infrared rays. That is, the indoor activity detection sensor 10 is installed in each room, constantly monitors the movement of people in the room, and is configured to output a detection signal when the presence of a person is detected. Behavior detection sensors 11 and 1
2 is configured to output a detection signal when the presence of a person is detected in the bathroom and toilet, respectively. The control circuit section 2 of the control device 1 uses the detection signals from these sensors to detect when the detected person does not move for a long time,
It is determined that there is an abnormality if the behavior pattern of bathing or using the toilet is different from the daily bathing or toilet usage time, such as when the bathing time or toilet usage time is different from the one in which the toilet is used for a long time.

Reference numeral 13 indicates a speaker for confirmation message, reference numeral 4 indicates a bank activation release switch, and reference numeral 15 indicates a telephone line.When the control circuit section 2 determines that there is an abnormality based on the signals from the various detection means and notification means described above, it first outputs a confirmation message. Activate circuit 4 and output a confirmation message via speaker 13.
Ru. If the notification activation/cancellation switch 14 is not operated, the telephone I/F 5 is activated to connect the control device 1 to the telephone line 15, and a notification is sent to a predetermined destination.

This embodiment has the configuration described above, and FIG. 3 shows a flowchart of the operating procedure.

First, in step S1, the presence or absence of the notification signal A□ from the portable notification transmitter 6 is determined, and in step S2, the presence or absence of the notification signal A2 from the indoor notification switch 7 is determined, and if there is a notification signal, the signal is Latch and start timer T2 built in the control circuit section 2 (step S3)
. If there is no notification signal, the process proceeds to step S4, and it is determined whether the user is at home based on the signal from the going out detection sensor 8. If the user is not home, the process returns to step S1, and if the user is home, the process proceeds to step S5.

In step S5, first, in step S51, a monitoring timer built in the control circuit unit 2 is activated, and then in step S52, signals from the behavioral inspection sensors 10 to 12 are detected, and if the presence of a person is not detected, is step S53
to reset the timer and return to step S1, and if a person is detected, proceed to step S54 and step S1.
55, the process returns to step S1 and repeats the above-mentioned procedure until the reference time for determination has elapsed, and when the person detection continues until the reference time has elapsed, the process proceeds to step S6, where the confirmation message output circuit 4 is activated and the confirmation message is activated. When the message is output, the process proceeds to step S3 and starts timer T2.

Although FIG. 3 shows them all together for the sake of simplification, in reality, the procedure of step S5 is performed for each of the three types of behavioral inspection sensors 10 to 12, and the reference time for one judgment also differs depending on the sensor. The time is set. Further, step S54 is a step of correcting the reference time for determination by averaging the daily activity time, and thereby the reference time is automatically set while being corrected as needed.

In the next step S7, it is determined whether or not the notification activation release switch 14 has been operated, and if it has been operated within the set time of the timer T2, the timers T□ and T2 are cleared and the notification signal A
1 and A2 are released and the process returns to step S1. Furthermore, if the timer T2 is not operated within the set time, the timers T□ and T2 are cleared in step S8, and the notification
The latches of No. A and A2 are released, and the process proceeds to step S9, where the telephone I/F 5 is activated. and step S
When a predetermined destination is called in step 10, a preset notification message is played and an abnormality notification is made. If the other party does not appear, return to step S9 and
A report is made by sequentially calling the other parties in the lower ranks.
When the notification is completed, the process returns to step s1.

<Effects of the Invention> As is clear from the embodiments described above, the present invention detects the presence of a person and outputs an abnormal signal when this detection continues for a long time.

Therefore, if a person does not move for a long time based on daily behavior patterns, it will be judged as an abnormality and will be automatically reported, making it possible to prevent and prevent situations that could lead to serious problems due to lack of notification. - It is possible to obtain a device suitable for detecting abnormal conditions of elderly people living alone.
