This is a block diagram of the room monitor controller provided for each room. 1 is a CPU (microcomputer), 2 is various sensors connected to this CPU 1 through an interface unit (hereinafter referred to as IFU) 3, gas, fire , Equipped with gas valve, water level sensor, etc.
4 is also a load connected to the CPU 1 via IFU5,

Reference numeral 6 is a display unit for inputting and displaying the signal from the CUU 1 through the IFU 7, and is composed of a liquid crystal, and displays necessary items such as date, time, fire and gas. 8 is a drive operation switch, and is equipped with a plurality of switches for turning on / off each of the above loads.
It is connected to the CPU1 via the IFU9. A room monitor controller having such a configuration is connected to a transmission line 11 via an interface module (IFM) 10, and is connected to a room monitor controller provided in each room via the transmission line 11. In other words, the CPUs distributed in each room perform local processing, and then the room monitor controllers in other rooms are also notified of the change via the transmission line. NEC Technical Report. VOL35, NO9,
The home control device described in 1982 is also an independent system, and if the home monitor body, fire sensor, gas leak sensor, ventilation sensor, water leak sensor, intrusion sensor are connected and the sensor detects an emergency state In addition to providing an emergency notification, it also controls the operation of the ventilation fan in conjunction with it when a fire or gas leak is detected. The system having these configurations is to perform centralized control of terminal equipment and notify when an emergency state is detected from various sensors.

Problems to be Solved by the Invention However, in the above-mentioned configuration, if the occurrence of a fire or the like is detected, each controller is informed of the emergency, and if it says, it is merely to stop the operation of the ventilation fan in conjunction with it. . In the case of a real home, when there is a fire or an earthquake, it is meaningless to just inform, and it is necessary to raise the system up to the point where the operation of burning appliances is stopped. In addition, the centralized controller connected to the transmission line is equipped with a timer control function that turns on the burning appliance at any time and minute, and when it is driven, a fire, an earthquake, etc. occur and it is linked to it. However, even if the combustion appliance is stopped by the above, if the operation of the combustion appliance is turned on by the timer immediately after that, there is a problem that the interlocking control for a complete emergency cannot be performed.

Means for Solving Problems In order to solve the above problems, the home control device of the present invention controls a sensor load control unit that monitors a sensor group such as a fire sensor and an earthquake sensor, and a terminal device such as a burning appliance. A terminal device control means for monitoring, and a controller control means for centrally controlling and monitoring the terminal device, and further having a time means for controlling the terminal device by a timer,
Each control means is an interface unit (hereinafter
In a home control device connected to a transmission line via an IFU), if the sensor load control means detects the occurrence of a fire, an earthquake, etc., the sensor load control means stops the operation of the terminal device, It has a function of sending a control command for invalidating the function of the timer means included in the control means to the transmission path.

Action The present invention operates as follows with the above configuration.
The following items are connected to the transmission line via IFU. (1) Sensor load control means that detects the occurrence of fire, earthquake, etc. and sends the emergency information to the transmission path, (2) Centralized monitoring and on / off control of terminal equipment such as gas equipment, air conditioners, and water heaters. In addition, a controller control means having a timer function for turning on / off each of these devices at any time and minutes, and (3) terminal device control means for individually controlling / monitoring terminal devices such as gas equipment are organic. Are combined together.

It is assumed that the combustion appliance is in the operation operation state now, and the controller control means is driven by the timer function of turning the combustion appliance on again at 6:30 AM. The current time is 6:28 AM. At this time, the sensor load control means detects an earthquake. Then, the sensor load control means generates a data packet for occurrence of an earthquake and a data packet (control command) for stopping the operation of the terminal device, and sends the data packet to the transmission path via the IFU. The terminal device control means coupled to the burning appliance receives the data packet for stopping the terminal via the IFU and stops the burning appliance. If left unattended, the operation will start at 6:30 AM according to the instructions from the controller control means, despite the earthquake. In order to prevent this, the controller control means operates so as to invalidate the timer function when an earthquake occurrence data packet is received.
