In particular, central control of a plurality of controlled units is carried out. At that time, each controlled unit is addressed, and the remote controller transmits data such as operation commands to each unit, and each unit also sends information about the operating state to be controlled based on that data. Data is sent to the remote controller. In this way, individual control (operation control and monitoring control), group control (control in which the operation commands are in the same mode), or centralized management control of the controlled units is performed.

However, in the conventional control system as described above, it is necessary to store the operation command mode and operation state mode of each controlled unit in the central control device.
There was a problem in that the storage capacity of the central control unit increased and the system configuration was restricted.

). If the predetermined data transmission is not completed, the transmission flag remains at 1 and the transmission process in step 403 is continued.

In the above step 402, if the transmission flag is 0, the process proceeds to step 407, and it is determined whether the reception flag is set to 1. If it is set to 1, step 40
At step 8, a reception processing routine (not shown) is executed and received data (operating status data) is input bit by bit. Then, it is determined in step 409 whether reception of a predetermined number of received data has been completed, and if it has been completed, the reception flag is set to O (step 410), and if it has not been completed, the reception flag remains 1, and step The reception process in step 408 continues. Furthermore, if the reception flag is set to 0 in step 407, input processing (step 411) and output processing (step 412) of signals from each switch are performed.

FIGS. 5 and 6 show flowcharts of an output processing routine (step 412) that executes arithmetic processing according to the data input in step 411.

First, in step 501 of FIG. 5, it is determined whether the unit address is in manual mode or not. If the unit address is not in manual mode but in automatic mode, it is determined in step 502 whether the advance timer (not shown) has completed counting operation. . If completed, determine whether the unit address is the highest address within the controllable range (step 503), and if it is the highest address, set the unit address to 0 (step 5o4), then add 1 to the unit address. (Step 5o5). next.

In step 506, it is determined whether the selection switch 10 for selecting a specific unit is ON, and if it is ON, the timer is set (Step 507).

The transmission flag is set to 1 (step 508) and the display output is cleared (step 5o9). That’s it, step 5
In steps 02 to 509, when the unit address is in automatic mode, the unit address is changed at regular intervals set by the timer, and data is transmitted only to the air conditioner 2 of the unit address selected by the selection switch 10 at that time. .

In step 501, if the mode is manual, each switch and switching mechanism 19, 21, 23, 25, 2γ
The operation command change flags that are set independently when are operated are all reset to 0 (step 510).
. Next, it is determined whether a signal from the unit address change switch 32 is being input (step 511), and if this signal is being input, the unit address is changed by an operation switch input processing routine (not shown); If so, set the unit address change flag on the IK (step 512).
Clear the display output (step 513). Then, the process advances to step 514, and it is determined whether the timer's counting operation has been completed.

At step 02, the unit address is displayed, and at step 603, predetermined data such as the unit address, operation command, contents of the operation command change prohibition flag, etc. are set in the transmission data. If the transmission flag is set to O, the process proceeds to step 604, and it is determined whether the mode is setting mode.If not, if the mode is monitor mode, the received data is displayed and output in step 605, and the process proceeds to step 602. If it is the setting mode in step 604, the process proceeds to step 606, and it is determined whether each switch or switching mechanism 16, 19, 21, 23, 25, 27 has been operated, and if any operation signal is input, the input The operation command change flag of the switch that has been set is set to 1 (step 607), the transmission flag is set to 1 (step 608), and a timer is set (step 60).

The unit address change mode is set to automatic by the changeover switch 31, but if it is set to automatic without the individual control circuit 11 being connected, the operation command of the operated switch is set to a fixed value by the changeover switch 31. The operation command of the unit (air conditioner) whose unit address has completed data transmission is changed until the data transmission is completed.

When the power is turned on, a power-on reset is performed, and initial setting is performed in step 701 to set data to initial values. Next, in step 702, although not shown, it is determined whether a reception flag, which is set to 1 when an interrupt signal is input from the transmitter/receiver circuit 4, is 1 or not. If it is set to 1, the process advances to step 703 to execute a reception processing routine and input the received data bit by bit. Then, it is determined in step 704 whether reception of a predetermined number of data has been completed, and if it has been completed, step 704 is performed.

In this routine, first, in step 801, it is determined whether the address set by the address designation switch 14 and the address included in the received data match.
If they match, a valid flag is set to 1 to enable data import (step 802). Next, the process advances to step 803, and one of the operation command change flags in the received data is
It is determined whether any commands are set to 1, and if any commands are set to 1, only those driving commands are changed according to the received data (step 804).

Further, FIG. 9 shows a flowchart of the transmission data processing routine in step 712 described above.

In step 901, it is determined whether the above-mentioned valid flag is 1, and if it is 1, the process proceeds to step 902, where it is determined whether the received data requests setting mode or monitor mode. If the setting mode is requested, the contents of the operation command and operation command prohibition flag are set in the transmission data (Step 903); if the monitor mode is requested, the contents of the operation state and the operation command change prohibition flag are set in the transmission data. (Step 904). And step 9
The process proceeds to step 905, where the valid flag is reset to 0, and the transmission flag is set to 1, at step 906.

Although the operations of the remote controller 1 and the air conditioner 2 have been described above according to each flow chart, it is also possible to further expand this control system to have a system configuration as shown in FIG. 10, for example. That is, the individual control circuit 11 is connected to the remote controller 1a, and control unit selection switches (not shown) at addresses 1 to 8 are turned on. In addition, remote controller 1b

Similarly, control unit selection switches at addresses 4 to 5 -6 to d' of the remote controllers 1c and 1d are turned ON, respectively. The units 41a to 41h controlled by the above remote controllers are respectively set to addresses 1 to 8 in order by address designation switches.

In the above system configuration, remote controller 1
a represents individual control (operation control and monitoring) of each unit) 41a to 41h, other remote controllers 1b, 1c,
The remote controller 1b can control the prohibition and permission of operations of the units 41a, 41b, and 4.
1c's individual control, remote controller Ic is unit 41d.

The remote controller 1d can perform individual control of the units 41e, and group control of the units 41, 41q, and 41h (control in which the operation command is in the same mode).

Centralized management can be performed using the remote controller 1a, and a large number of controlled units such as air conditioners can be controlled.
There is no need to remember the operating mode.
