Title: Timer judging circuit
Inventor: ISHITA TORU
IPC: G01S1/54
Filed: 1988-04-26
Abstract: PURPOSE:To check regularly all paths at parts where MV cannot be performed in a conventional circuit, by separating a part for monitoring an actually transmitted signal and a part for judging monitor verification MV, and controlling both parts. CONSTITUTION:Measured angle error data 101 are inputted into a digital comparator 102 as an input for a timer judging circuit. Meanwhile, allowable angular error range data 103 are inputted into the comparator 102 as reference data for comparison. Whether the error data 102 are within the range of the data 103 or out of the range is judged in the comparator 102. When, the actually measured data are within the allowable error range (normal time), an output 104 is low and an output 105 is high. Meanwhile, when the data exceed the allowable error range (abnormal time), the output 104 is high and the output 105 is low. The outputs of the comparator 102 are split and inputted into electronic switches 106 and 107. The outputs are further inputted into abnormal- continuation judging circuits 108 and 109.

With switch 131, a maintenance reception channel number is assigned and a signal reception state read command for a receiving channel for maintenance is supplied at intervals of 32ms to check the reception state of the above-mentioned digital pattern. Then when not greater than two pulses or not less than five pulses are detected continuously at intervals of 32ms, for example, a decision on a signal fault is made and the in-use signal is changed over to a stand- by signal. Therefore, stand-by switching of signals can be performed rapidly without external controller.
