PURPOSE:To reduce the callout period to a station to be monitored, by performing the processing of response information from the station to be monitored called from a supervisory station after the callout to the next station to be monitored. CONSTITUTION:When response information (n-2)'' from a station (n-2) to be monitored is received, a monitor station M produces a callout signal (n-1)' to the next station (n-1) to be monitored, performs the response information (n-2)'' until the response information (n-1)'' is obtained, and after the end of processing, the reception of the response information (n-1)'' is awaited. In receiving the response information (n-1)'', a call signal n' is transmitted to the next station (n) to be monitored immediately, and the response information (n-1)'' is processed until the response information n'' is received. The station to be monitored is called through the reception. |
