MICROPROCESSOR SYSTEM FOR DIESEL LOCOMOTIVE TRACTION GENERATOR VOLTAGE ADJUSTMENT Russian patent published in 2013 - IPC B60L15/20 

FIELD: transport.

SUBSTANCE: invention relates to railway transport, particularly, to means of adjusting excitation current in electric transmission of diesel locomotive with self-contained heat engine. Proposed microprocessor system comprises diesel engine coupled with transition generator make diesel-generator set, exciter rigidly coupled with diesel engine, traction generator voltage transducer, traction generator load current transducer, diesel-generator rpm transducer, and pickup to indicate fuel feed to diesel. Microprocessor controller comprises first and second setting devices, 1^st, 2^nd and 3^rd comparators, pneumatic brake control unit, motion mode computation and operating conditions indication unit, and interface. Note here that said controller is provided with functional converter with input connected with diesel-generator shaft rpm transducer output and outputs connected with 1^st input of 3^rd comparator and 1^st input of adder, integrator with output connected to adder 2^nd input. Adder output is connected to 1^st input of 1^st comparator. Comparator 2^nd input is connected to multiplier output.

EFFECT: optimised automatic control.
