DEVICE FOR TRAFFIC MONITORING Russian patent published in 1997 - IPC

FIELD: centralized monitoring of vehicles which follow transport route. SUBSTANCE: device according to patent application 1538178 is extended by introduction of fault vehicle code request into request cycle of vehicle. This code is repeated in request loop after equal time intervals, for example each second. Vehicle equipment also has fault request unit, number comparator, multiplexer. Control office has algorithm of fault vehicle request and processing of emergency call. Output of emergency call unit is connected to input of keyboard, first input of multiplexer, and fourth input of number comparator, which first, second and third inputs are connected to corresponding outputs of start verification unit. First output of number comparator is connected to first input of control unit and input of emergency call. Second, third and fourth outputs of number comparator are connected to input of digital-to-analog converter, input of start signal generator and third input of multiplexer, respectively. Second input of multiplexer is connected to output of transport route code detector. Output of multiplexer is connected to first input of encoding unit. EFFECT: increased response speed due to introduced emergency call system. 2 cl, 11 dwg
