Embodiment 1

[0048] Such as image 3 As shown, it is the schematic diagram of the circuit used for the test of the above-mentioned fault diagnosis device connected to the track circuit. Taking the track circuit of the electrified section as an example, when dealing with the fault of the track circuit, the track circuit of the faulty section receives power terminal corresponding to the lightning protection distribution cabinet in the mechanical room, that is, image 3 Remove the indoor circuit at places a and b in the middle, and connect the load access terminals A and B of the portable railway fault diagnosis device. If the test data displayed by the diagnostic output module returns to normal, it is diagnosed as an indoor fault. Continue to check the track relay, protective box, and indoor fault. For the power supply and wiring part, if the test data does not return to normal after connecting to the simulated load module of the portable railway fault diagnosis device, it will be diagnosed ...

Embodiment 2

[0050] Such as Figure 4 As shown, when dealing with signal machine circuit faults, take the lighting circuit of a light position of the shunting signal machine as an example, at the wiring terminal of the lightning protection distribution cabinet in the mechanical room corresponding to the light position of the faulty shunting signal machine, that is Figure 4 Remove the outdoor cable terminals of the signal machine at a and b, and connect them to the load access terminals A and B of the portable railway fault diagnosis device. If the test data displayed by the diagnostic output module returns to normal, it is diagnosed as an indoor fault, and check the corresponding filament relay. DJ coil, DXJ relay contact, indoor wiring, XJZ-220 power supply and fuse part. If the test data displayed by the diagnostic output module is not recovered, it is diagnosed as an outdoor fault, and continue to check the signal lighting transformer BX, outdoor cable, signal mechanism and filament. ...

Abstract

The invention relates to a portable railway fault diagnosis device and a diagnosis method thereof, and belongs to the technical field of rail transit. The device comprises a protection box, and an analog load module, an acquisition test module, a CPU processor module and a diagnosis output module which are arranged in the protection box, the analog load module comprises a change-over switch and six branch circuits corresponding to the change-over switch, so that six simulation load circuits are formed. The six branch circuits comprise resistors R1-R6, capacitors C1-C2 and inductance coils L1-L2; and the device is suitable for processing and analysis of a railway electric service field work area under the condition that signal equipment faults occur, and fault properties are judged rapidly and accurately, the fault range is narrowed, and fault time delay is compressed by testing the simulation load at the signal machine room distribution board. The device can complete fault diagnosis and parameter test of 25Hz phase-sensitive track circuits and annunciator circuits of different systems.

Description

technical field [0001] The invention relates to a portable railway fault diagnosis device and a diagnosis method thereof, belonging to the technical field of rail transit. Background technique [0002] The safety of railway transportation is the basic guarantee for realizing the overall efficient operation of railways. The 25Hz phase-sensitive track circuit and signal circuit widely laid in the railway section are the basic equipment of the train operation control system. The normal operation of the track circuit is an important guarantee for the safe operation of the train. Outdoor equipment such as track circuits and signaling machines are easily affected by complex environmental factors such as temperature and humidity, and also due to the operating conditions of various components of the system, track circuit failures occur from time to time, and the results will affect railway operation efficiency and even traffic safety. When the existing track circuit fails, it main...
