FIG. 5 is a flow chart showing the main operation of the microcomputer 22 of the device 2. Microcomputer 2 in step S1
2 is initialized and the operation is started. In step S2, it is determined whether or not one pulse is given to the terminal HAI. When the pulse is given, the process proceeds to step S3, and the timer starts counting the predetermined time Tc, and when the pulse is not given, it will be described later. Proceed to step S5. Next, at step S4, the number of pulses N (N at initialization)
= 0) count is added. Then, in step S5, it is determined whether or not the timer has timed up. Time U
If not, the process proceeds to step S15 described later. If the timer is up in step S5, step S5

The operation of a signal conversion unit that converts the 0FF signal into a control signal is performed.

When 2 is restricted, the process directly proceeds to step S17.

In step S17, the operation of the equipment is controlled based on the control signal. For example, when there is an ON signal (control signal), the equipment is operated. Since the step S16 is not executed when the restricting operation is being performed, all the control signals generated by the operation on the device side are invalid (operation of the restricting unit). Since the ON / 0FF signal output from the centralized controller is valid, the ON / OFF signal obtained by converting from this signal

A serial signal (modulated wave) whose frame is composed of a destination address, a source address, and data is used for signal transmission / reception between the centralized controller and the interface unit. Therefore, a unique address is set in advance in the interface unit. In the embodiment of FIG. 6, it is possible to perform centralized control of many devices without increasing the number of signal lines.

Further, in the above-described embodiment, since each device needs to judge the regulation signal, the existing device (the device already installed) cannot perform the regulation operation, but as shown in FIG. If the interface unit is configured on the existing equipment, the regulation operation can be performed.

In FIG. 7, the same components as those in FIG. 2 are designated by the same reference numerals and the description thereof will be omitted. Reference numeral 40 denotes a microprocessor (hereinafter referred to as a microcomputer), which performs the main operation of the interface unit. Reference numeral 41 is a modulation / demodulation circuit, which demodulates the signal from the two-line signal line 35 and
The signal is output to the signal line 35 by modulating the carrier wave with the signal from the microcomputer 40. An address setter 42 sets a unique address of the interface unit. Therefore, the microcomputer 40 takes in and controls only signals whose addresses match.

FIG. 8 is a flow chart showing the main operation of the microcomputer 40 shown in FIG. First, in step S20, power supply to the microcomputer 40 is started, the microcomputer 40 is initialized, and then the process proceeds to step S21. In step S21, it is determined whether or not a signal with the same address is input. When a signal is input, step S22,
In step S24 and step S31, whether the input signal is the ON / 0FF signal, the regulation signal, the operating state of the device,
It is determined whether the signal is a signal requesting a reply on the regulation status of the device.

When the ON / 0FF signal is received, the process proceeds to step S23, and one pulse as shown in FIG. 3 is output to the device via the interface section 15. In response to this signal, the device changes the operating state of the device from ON to 0FF or 0
Change from FF to ON.

When the regulation signal is received, step S2
Go to 5 depending on whether the device is currently in regulation
In step S26 or step S27, the regulation is released or the regulation operation is started. Next, in step S28, it is determined whether or not the device is currently in the regulation operation. When the device is in operation, the process proceeds to step S30 and the pulse is output as in step S23. Therefore, by performing steps S28 to S30, even if the device changes to the operating state during the restricting operation, a pulse is automatically output to stop the device. That is, it means that the control signal from the operation unit is substantially invalidated. The operating state of the device can be known from the voltage level applied to the terminal FO of the microcomputer 40 via the interface section 15.

When the reply signal is received in step S31, the process proceeds to step S32, and the signals of the operating state of the equipment (voltage level applied to the terminal FO of the microcomputer 40) and the regulation state (whether or not regulation) are used as carrier waves. It is put on and output to the signal line 35. The source address is set to the address of the interface unit, and the destination address is set to the address of the centralized controller.

With the above-mentioned structure, it is possible to substantially regulate even a device having no regulating operation function.
