Abstract

PURPOSE: To achieve and initializing start by initializing forcedly a micro processor when line disconnection is detected in the controlled place side, in the initializing unit for the centralized supervisory control system equipped with a transmission system.
CONSTITUTION: Controlling place-side unit 1 is connected to the controlled place- side unit through modulator 5, switch 6 which opens the communication line, the communication line and demodulator 7 of the controlled place side. The demodulator 7 above has a line disconnection detection function and applies detection signal b to gate 11 of initializing control part 12 at a detection time. By applying signal b, reset signal e from micro processor 10 is locked, and signal f is not transmitted. Then, since oscillation signal c from oscillator circuit 8 is not reset after a set time of counter 9, the signal is applied to micro processor 10 as initializing request signal d, thus initializing.
