When the reception determination unit 21 determines that there is an abnormality, the abnormality determination unit 2
Proceed to step 2. A is a first counter, and 23 is a first counter that counts the number of passes when the abnormality determination unit 22 does not determine that reception is abnormal. 24 is the first kakunku!
In the leap section, it is determined whether the first power kunk 23 has completed counting. Once completed, the process proceeds to the second counting section B. The abnormality flag setting unit 25 sets a flag indicating that the remote control device with which the communication has occurred is in a communication abnormality. second counter 26
counts the number of times the error flag has been set. Next, the second counter determination unit 27 checks the count status of the second counter 26 with I! ll determine.

The abnormality flag determining unit 28 determines whether the abnormality flag is set, and if it is not set, the process proceeds to the first polling setting unit 29 and selects the next l/i'' address 2 of the remote control that should be attached. Also, when the abnormality flag is set, the process proceeds to the second polling setting section 30 and sets the address of the remote control device next to the remote control device to be received next.The second counter 26 counts When the count is up, the process proceeds to a third counting unit C, which counts how many times the second counter 26 has exceeded the count.
If 1 has not completed counting, the process returns to the first polling setting section 29, and 1 is completed. The process branches to a U-blade constant flag setting section 33.

と、(c動される。If the transmitting/receiving device 1 and the remote control devices 2a, 2b, 2c are communicating normally, the processing unit 34 performs a take process and the first
The process advances to the polling setting section 29 and all next remote control devices are designated. Next, the transmitter 19 transfers the take to the designated remote control device, and the receiver 2O receives data from the other party. Here, if reception is not possible for some reason, it branches from the reception determination section 21 and sends the first
Proceed to counting section A. The first counter determination unit 24 does not process the take and ignores it when the count is not up. This state is repeated and the first counter 23
When the count is up, the abnormality flag setting section 25 sets a flag indicating an abnormality in communication with the remote control device. Thereafter, the abnormality flag is checked in the abnormality flag determining section 28, and when it is set, the process proceeds to the second polling setting section and the next remote control device is specified without specifying the address of the remote control device indicating the abnormality. In this way, the normal remote control device 2a
, 2b, 2cl The first and second counters 26 communicating with the transmitting/receiving device 1 have a function of giving an opportunity to output a transmission request to the remote control device on which the abnormality flag has been sent. When the second counter 26 completes counting, the first counter 23 is moved (c).

When it reaches a certain number of times, it is considered to be a complete failure, and the abnormality confirmation flag setting section 33 sets a confirmation flag, and thereafter communication with the transmitting/receiving device 1 is stopped.

If normal communication becomes possible during this time, the polling cycle will be returned to the original one. On the other hand, if the abnormal condition continues for a long time, communication will be stopped in order to use the line more efficiently.
