PURPOSE:To make possible remote monitoring and testing of condition of the local stations by transmitting the memories of the local stations to the central station in response to the commands of the central station. CONSTITUTION:A central station C/C sends prefixed control signals to lcoal stations S/S, a microprocessor CPU of each local station detects the control signal and changes programs, then sends memories of the local station to the central station C/C. A typewriter T/W of the central station C/C typewrites the messages from the local stations to record the memories of the local stations S/S, thus finding any abnormal condition in the local stations at the central station. |
