Send to. The monitoring device receives this monitoring input signal 15.
The monitoring device uses the station selection control circuit 7 to select the next station based on the reception of the station selection control circuit 7. [Problem to be Solved by the Invention] In the conventional monitoring device described above, the monitored device collects information using a control signal for station selection. In order to start monitoring, if the monitored device is a low power consumption type, the power supply is stopped until the control signal is received, and the power is supplied only when the information collection starts upon reception and the monitoring information is sent to the monitoring device. If the station has measurement information and starts measurement by receiving a control signal for pole selection, it takes a long time to collect information from receiving the control signal for station selection to sending monitoring information to the monitoring device. Therefore, there is a drawback that a very long time is required from sending out the control signal for station selection of the first station until receiving the final monitoring input signal from the monitored device of the 0th station.

た。In addition, when the monitoring information includes measurement information and you want to compare and judge the measurement values and monitoring status of each station where each limb monitoring device is installed, it is necessary to process if there is a time difference between the measurement time of each monitored device and the time of the monitoring information. The problem is that it is difficult. Another problem is that it takes too much time to know the latest monitoring status.
