FIELD: railway automatics. ^ SUBSTANCE: device incorporates a set of output transformers, a load, a portable PC, a digital storage oscilloscope, a stabiliser, a code combination selection and diagnostics relay state control module, a signal shaper supply control module, an instruction processing and distribution module and a switching module. The method consists in simulation of sync-groups and SS-EN code selection straps, reception and decoding of phase-processed signal from SS-EN, checking the code combination for validity, simulation of the said strap faults, connection of the oscilloscope module to appropriate measuring resistor depending upon the type of measurement required, control over power supply to SS-EN (rated, maximum and minimum voltage values), transmission of obtained results into the portable PC. ^ EFFECT: high-efficiency diagnostics, process automation. ^ 9 cl, 1 dwg |
