Abstract

The invention provides a detection circuit and a detection device for an automatic neutral section passing system. The detection circuit comprises a first switching unit which is configured to converta power supply of an input end into a first parameter power supply after being closed, and output the first parameter power supply from an output end; a second switch unit which is configured to convert the power supply of the input end into a second parameter power supply after being closed and output the second parameter power supply from the output end; a vehicle induction coil signal simulation unit which is connected with the output end of the first switch unit and is configured to simulate an input signal of a vehicle induction coil to the automatic neutral section passing system; a vehicle induction coil fault simulation unit which is connected with the output end of the second switch unit, and is used for disconnecting the second switch unit and the automatic neutral section passing system when the simulated vehicle induction coil has fault, and connecting the second switch unit and the automatic neutral section passing system in response to the input signal when the simulatedvehicle induction coil has no fault; and a detection unit which is connected with the output end of the first switch unit, and is used for acquiring the output signal of the automatic neutral sectionpassing system and outputting a matched detection signal according to the output signal.

Description

technical field [0001] The present disclosure relates to the technical field of locomotives, in particular to a detection circuit and a detection device of an automatic phase separation system. Background technique [0002] At present, there are many models and suppliers of automatic phase separation systems for assembling locomotives. The used detection and maintenance equipment are bulky and complicated to operate. The key detection and maintenance processes are in the hands of the manufacturer, which brings a great bottleneck to the detection and maintenance of the automatic phase separation system. Manufacturers and users are far apart and need to return to the factory for repairs. Customer needs such as non-stop maintenance and short maintenance cycles cannot be met. [0003] In this context, portable and easy-to-operate testing equipment that meets on-vehicle and off-vehicle maintenance has become the actual need for maintenance. [0004] It should be noted that the...
