FIELD: transport.SUBSTANCE: transmitter contains diagnostic module, switching module and control unit. The transmitter has following devices included in it: electromagnetic relay, controlling and monitoring microcontrollers, optoelectronic transducer, pulse transformer and control unit for electromagnetic relay the winding of which is connected with switching module output and contact group of electromagnetic relay is connected with plug coupler. Herewith, the first inputs of controlling and monitoring microcontrollers are connected with control unit outputs, and the second input of controlling microcontroller is connected with diagnostic module connector. The first output of controlling microcontroller is connected with the first input of optoelectronic transducer, the second output of controlling microcontroller is connected with the second input of optoelectronic transducer via pulse transformer, the first output of monitoring microcontroller is connected with one indicator, and its second output is connected with other indicator. The third output of monitoring microcontroller is connected with the third input of optoelectronic transducer the first output of which is connected with contact group of electromagnetic relay.EFFECT: longer operational life of transmitter due to backing-up signals and diagnosing transmitter state and design simplification.1 dwg |
