  As shown in FIG. 5, the protocol conversion control unit 60 communicates with the RS485 communication IF 57 that is connected to the external device IF 16 of the management control device 3 so as to be capable of mutual communication with the RS485 communication protocol that is the first communication protocol. A serial communication IF 59 that is communicably connected to the hot water supply unit 35 and a conversion-side remote control communication IF 58 that is a second communication interface that is connected to the second terminal-side remote control communication IF 45 of the home terminal 6 so as to be able to communicate with each other using a remote control communication protocol. Via the RS485 communication protocol, the remote control communication protocol, and the serial communication protocol.

  The system 1 having the above configuration operates as follows. First, in the management control device 3, a predetermined calculation is executed by the power measurement processing unit 13 based on the current information input to the current sensor IF 12 and the voltage information detected by the voltage value detector 20 in the management control device 3. Then, the power of the measurement target circuit is calculated. Further, the calculation processing unit 19 calculates the amount of power used (the amount of received power from the commercial power system) from the hourly power data. This calculation data is stored in the storage unit 18 each time. On the other hand, the gas usage is calculated based on the gas usage information output from the gas usage detector 23 in the hot water supply unit 35 and input to the external device IF 16 of the management control device 3 via the protocol conversion control unit 60. Similarly, it is stored in the storage unit 18.

  The arithmetic processing unit 19 functions as an arithmetic display control unit and creates a graph on the Web page according to a preset format. For example, on the Web page, the amount of electric power used for each hour is indicated by a line graph, and the amount of generated electric power such as the amount of gas generated electric power or the amount of electric power generated by photovoltaic power is indicated by a bar graph. In addition, instantaneous power (used power) is shown by a bar graph at predetermined time intervals. Further, as another Web page, the magnitude of the generated power and the used power may be displayed as numerical values and may be displayed as a belt-like graph. Moreover, you may display with an arrow whether it is in a power receiving state or is selling electricity. This Web page is also created for gas and water as needed and stored in the storage unit 18.

  The Web page thus created can be browsed by connecting to the Internet network 32 if the external terminal 5 is a PC 33 or a mobile phone 34 equipped with a browser. However, a password is set in the management control device 3. From the external terminal 5, browsing is possible by inputting this password and transmitting a browsing request mail as browsing request information including a browsing request command statement of the Web page. The arithmetic processing unit 19 of the management control device 3 recognizes the password from the received browsing request mail, and permits access when it matches the set one. Further, the Web page is disclosed in accordance with the browse request command that has been extracted, and the Web page data is transmitted to the external terminal 5.

  The arithmetic processing unit 19 functions as a communication control unit, and notifies the home terminal 6 of the communication state of the browsing request mail. In the home terminal 6, the terminal control unit 49 determines the communication state of the browsing request mail corresponding to the communication state signal input from the terminal remote control communication IF 45. If the terminal control unit 49 determines from the communication status signal that the browsing request mail has been normally received, the terminal unit 49 causes the display unit 47 of FIG. After that, the display is turned on for a predetermined time.

  As described above, if the external terminal 5 includes a browser capable of displaying a Web page, the energy usage amount can be displayed on the screen via the Internet network 32, so that a dedicated display means can be used from outside. In addition, you can check the energy usage at home in an easy-to-read form. In the home 7 where devices using gas and power as different energies coexist, it becomes possible to manage the gas usage and the power usage at the same time. Further, since the communication state of the browsing request mail is configured to be notified to the home terminal 6, the home terminal 6 can check the communication state with the external terminal 5.

  Further, the storage unit 18 stores an upper limit value of power used and an upper limit value of gas used as reference values. The arithmetic processing unit 19 compares the calculated gas usage amount or power usage amount with the reference value, and if any one of them exceeds the reference value, the detected energy usage information is larger than the reference value. As a result, a comparison result mail which is comparison result information including the contents of the comparison result is transmitted to a predetermined external terminal 5 such as a mobile phone 34. The communication status signal corresponding to the communication status of the transmitted comparison result mail and the notification signal generated by the arithmetic processing unit 19 are output to the terminal remote control communication IF 45 of the home terminal 6. Thereafter, the device control unit 15 is controlled, and the corresponding energy using device is turned off.

  For example, a fixed sentence such as “The power has exceeded 1000 watts. The air conditioner is turned off.” Is created in advance, and the corresponding sentence is transmitted. Thereafter, when a predetermined time has elapsed, for example, the air conditioner 36 is turned off. In the case of gas, the same operation is performed, and a notification operation is performed and a turn-off operation is performed by transmitting a comparison result mail.

  In addition, the home terminal 6 determines the communication state corresponding to the communication state signal input from the terminal remote control communication IF 45 by the terminal control unit 49. If the terminal control unit 49 determines from the communication status signal that the transmission of the comparison result mail has been normally completed, the terminal control unit 49 causes the display unit 47 to flash the mail mark 55 with a predetermined envelope on the display for a predetermined time. Lights up for a predetermined time. If it is determined that the mail has ended abnormally, a cross mark is added to the mail mark 55 and displayed on the display unit 47 for a predetermined time.

  In this way, when the energy usage exceeds the reference value, an e-mail is transmitted to the external terminal 5 to notify the resident, so that the resident can know it even if he is not at home. Therefore, the resident can know that the energy usage situation at home has deteriorated from the outside, and can easily take necessary measures. In addition, the resident can know the comparison result including the content of whether or not the energy usage exceeds a preset reference value even when the user is away from home, and the area for grasping the comparison result can be expanded. In addition, since the communication status of the comparison result mail is notified to the home terminal 6, the communication status with the external terminal 5 can be confirmed by the home terminal 6, and if the comparison result mail has not arrived, By using an alternative means such as a telephone by a home person who has confirmed the wearing state, the contents of the comparison result mail can be more reliably transmitted to the user of the external terminal 5, and the reliability of the system 1 can be improved.

  In addition, when the reference value is exceeded, energy saving can be surely achieved by automatically turning off the related energy use device. Further, if the power setting is set in accordance with the power capacity of the home distribution board 21, it is possible to prevent the circuit breaker from operating and causing a power failure.

  Even when the human sensor 38 or the window sensor 39 is operated as a security device, an abnormality detection signal is input to the digital input IF 11 which is an abnormality detection signal input interface, and the calculation result of the energy usage amount and a preset reference value is accompanied. Similarly to the transmitted comparison result mail, if it is determined that the abnormality detection signal includes an abnormality, the abnormality state mail is transmitted to the predetermined external terminal 5 as abnormality state information including the content of the abnormality. The human sensor 38 is activated by switching the operation mode from the non-operation state to the operation state of the management control device 3 by pressing the switching operation button switch 46 of the home terminal 6.

  Here, when the switching operation button switch 46 is pressed, a pressing signal indicating the pressed state is output to the protocol conversion control unit 60 as remote control communication data. The protocol conversion control unit 60 converts the press signal into the RS485 communication protocol and outputs it to the external device IF 16 of the management control device 3. The arithmetic processing unit 19 switches the operation mode in the management state to the security operation mode by receiving the press signal. After switching, the arithmetic processing unit 19 outputs a display signal instructing display contents to the home terminal 6 via the protocol conversion control unit 60 in response to the press signal. Upon receipt of the display signal, the home terminal 6 displays, for example, a “watch” character string 56 on the display unit 47 of FIG. 3 as a predetermined character string indicating the content of the display signal.

  When the human sensor 38 detects intrusion (approach) of a person in the security operation mode, the human sensor 38 outputs an abnormality detection signal as security information. When the management control device 3 detects the abnormality detection signal, the contents of the abnormal state are judged from the abnormality detection signal, and an abnormal state mail including the content of the abnormal state is created in advance, such as “A suspicious person has been detected in the room”. The fixed form is transmitted to a predetermined external terminal 5. At the same time, a security buzzer 50 as a notification unit of the home terminal 6 rings and a character string 54 of “abnormal”, for example, is flashed on the display unit 47 of FIG. The same applies when the window sensor 39 performs a detection operation.

  With this operation, intrusion information of suspicious persons can be obtained as information indicating an abnormal state at the external terminal 5 on the go, crime prevention and disaster prevention can be performed more effectively, home security can be improved, and quick response is possible It becomes. Further, since the communication state of the abnormal state mail is notified to the home terminal 6, the communication state with the external terminal 5 can be confirmed by the home terminal 6, and if the abnormal state mail has not arrived, By using an alternative means such as a telephone by a home person who has confirmed the arrival state, the contents of the abnormal state mail can be transmitted to the user of the external terminal 5 more reliably, and the reliability of the system 1 can be improved.

  On the other hand, from the external terminal 5, the energy using device 2 connected to the device control unit 15 can be remotely controlled. The management control device 3 is set with a password, and the operation control information including an operation control command statement for controlling the operation of the energy using device 2 by inputting the password, the device name, and the operation state such as on / off from the external terminal 5. By transmitting the operation control mail as described above from the external terminal 5, it is possible to remotely control the energy using device 2 such as an electric device in the house even from the outside. When the arithmetic processing unit 19 of the management control device 3 recognizes the password from the operation control mail, the arithmetic processing unit 19 reads the operation target device and the operation control command, and controls the device control unit 15 to respond to the operation control command. And on / off operation of gas equipment such as the gas stove 37 and the like.

  Instead of the password, control may be performed by transmitting a predetermined mail from the pre-registered external terminal 5 to the management control device 3. In this case, a fixed phrase created in a predetermined format is stored according to the operation target or the type of operation such as ON / OFF, and the fixed phrase is selected and transmitted, as in the case of a password. The arithmetic processing unit 19 recognizes the operation target and the control content from the received mail, and controls the device control unit 15 to perform the on / off operation of the electric device and the gas device.

  As described above, since the gas device and the power device can be remotely controlled by mail operation via the Internet network 32 from outside, the energy usage amount in the home 7 can be surely reduced, and the energy can be saved. In addition, since the communication state of the operation control mail is configured to be notified to the home terminal 6, the home terminal 6 can check the communication state with the external terminal 5.
