DEVICE FOR CHECKING ON-BOARD EQUIPMENT OF AUTOMATIC LOCOMOTIVE SIGNALING (VERSIONS) Russian patent published in 2020 - IPC B61L25/02 

FIELD: hardware diagnostic systems.

SUBSTANCE: technical solution relates to means of control and diagnostics of onboard equipment of automatic locomotive signaling. According to one version of the invention, the device includes a switching and matching unit, inputs connected to a second output of the control unit and an output of the test signal generating unit, inductive coupling line connected to outputs of switching and matching unit and connected by inductive coupling to receiving coils of on-board hardware ALS, a first measurement unit inductively coupled to the inductive communication line, a second measurement unit connected to the inductive communication line, and two comparison units, one of which is connected to the output of the first measurement unit by an input, and second – input/output to output/input of second measurement unit, wherein output of first comparison unit is connected to first input of control unit, second input is to second output of test signal generating unit, other input of which is connected to output of memory unit, inputs/outputs of second measurement unit are connected to outputs/inputs of report generation unit, and output of second comparison unit is connected to second input of control unit, third input of which is connected to output of data input unit.

EFFECT: higher reliability of checking on-board ALS equipment.
