[Action]

With the above configuration, the plurality of terminal controllers respectively connected to the air conditioners receive operation signals from the central controller to the individual air conditioners, decode the contents of the operation signals, and connect the connected air conditioners. When it is confirmed that the operation signal to the remote controller is different from the signal format of the operation signal from the central controller, the operation signal is output to the remote controller receiving circuit of the air conditioner in the same signal format as the remote controller. Since the operation setting is performed by the operation control, the operation of each of the plurality of air conditioners can be centrally controlled by the central control device.

Further, it is not necessary to add an input circuit dedicated to the centralized control device to the terminal controller of the air conditioner.

〔Example〕

An embodiment of a centralized control device for an air conditioner according to the present invention will be described below with reference to the drawings.

The centralized control device A is composed of a central controller 1 and terminal controllers 2a, 2b, 2n connected by a line. The terminal controllers 2a, 2b, 2n are connected to the air conditioners 3a, 3b, 3n by lines.

FIG. 2 shows the terminal controller 2 and the main controller 4 of the air conditioner 3.
It is explanatory drawing which showed the internal block diagram. Inside the terminal controller 2, the line from the central controller 1 is connected to the receiving circuit 9, and the receiving circuit 9 transmits to the terminal microcomputer (hereinafter referred to as the terminal CPU) 10. The output signal of the terminal CPU 10 is connected to the remote control device reception circuit 7 of the air conditioner 3 by the transmission circuit 11, and the remote control device reception circuit 7 is connected to the main body control device 4. The main body control device 4 has an output circuit for operating each part of the air conditioner 3.

To do. The received signal is sent to the terminal CPU 10. When determining that the control signal is present, the terminal CPU 10 proceeds to step SP2 and confirms whether the control signal matches the predetermined machine number of the air conditioner 3. If it is determined that they match, the contents of the control signal are decoded in step SP3. When the decoding is completed, the process proceeds to step SP4, the signal is converted into a signal for controlling the air conditioner according to the content, and the process proceeds to step SP5 to transmit. That is, the signal from the terminal CPU 10 is sent to the remote control device receiving circuit 7 inside the air conditioner 3 by the transmitting circuit 11. The signal format transmitted at this time is transmitted from the wireless remote control transmitter of the individual remote control device, and the input terminal 6
It is of the same format as the signal transmitted through the remote control receiving circuit 7. The signal received by the remote control receiving circuit 7 is sent to the main body control device 4, and the main body control device 4 controls the operation of the air conditioner 3 according to the content of the signal.

When there is no control signal in step SP1, and in step SP2
If the machine numbers do not match, the process goes to step SP6 to enter the control signal input standby state, and the terminal controller 2 does not send the control signal to the air conditioner 3.
