TELESIGNALLING SYSTEM Russian patent published in 1995 - IPC

FIELD: guard signalling systems. SUBSTANCE: signalling system provides storage of signals at short-time failures of guard stubs. In order to improve truth of information, the mode of dynamic inspection of serviceability of members of the system is introduced. Units are brought into the circuit which helps to indicate signals of stub disturbances. Signal processing channel units are brought into the system; the units characterize condition of guard stubs as well as commands for taking and rejecting objects of guard. The channel units provide automatic transmission of set commands for new mode of operation, inspection and indication of serviceability of equipment which forms information signals and commands. Members are introduced into the system which provide transmission along the same transmission line which is used for output of telesignals of stubs condition. There is unit for checking of doing of commands ordered in the system. Number of objects under guard, temporal characteristics and other parameters of the system are determined by composition and connections among the units introduced into it: clock pulse generator, the first and the second telesignal detectors units, data processing channel units and parallel/serial code converter. EFFECT: improved truth of information of operation. 6 cl, 6 dwg
