Abstract

PURPOSE:To realize a quick detection of the fault for every part of the control unit, by duplicating the time-division multiplex circuit control unit having the switching function in order to secure the synchronous action and then giving a collation to the transmission data, i.e., each final output. CONSTITUTION:Collating circuits 4a and 4b are provided to circuit control units 1a and 1b each in order to secure the synchronous action. Circuits 4a and 4b deliver 1 when the different signals are supplied to the input and deliver 0 when the same signals are supplied respectively. These collating circuits check the final outputs of units 1a and 1b, and thus even the fault occurring at any part of the unit can be detected. At the same time, the parity checking circuit or the collating circuit of the register is provided to units 1a and 1b each. As a result, the fualt occurring at any unit can be detected easily in case 1 is caused at the outputs of circuits 4a and 4b.
