Testing device and testing method of passenger information display system for rail transit

Abstract

The invention relates to the technical field of communication, in particular to a testing device and a testing method of a passenger information display system for rail transit. The testing device is composed of a control host, a maintenance tool table and an equipment installation cabinet. At least one playing controller is arranged in the equipment installation cabinet. The maintenance tool table internally comprises a maintenance tool rack, a platform PIS screen, an LED screen maintenance platform and a vehicle-mounted PIS screen maintenance platform. A complete detection report is formed by lightening a screen in a streamlined manner, reading voltage and current of the detected screen, analyzing an image signal of a camera and uploading detection data to a control host; according to the invention, the fault of the tested passenger information screen can be automatically detected, the detection data can be automatically recorded, and the detection efficiency is improved; meanwhile, long-time automatic stability testing under the unattended condition is achieved, a testing report is generated, labor cost is saved, and safety is improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a test device and a test method for a passenger information display system of rail transit. Background technique [0002] At present, there are only a few testing equipment in China for the single component of the display screen of the passenger information system dedicated to rail transit, and there is a lack of a complete system for testing the whole machine. The existing technical solutions have the following disadvantages: [0003] 1. The existing technical solutions are purely manual detection of fault points, which cannot realize automatic fault detection, and it is difficult to standardize the operation process. Manual maintenance and inspection are easily affected by subjective factors, have great uncontrollability, may have large errors, cannot find fault points in time, and affect production efficiency; [0004] 2. The existing technical solution can only test a...

Problems solved by technology

[0003] 1. The existing technical solutions are purely manual detection of fault points, which cannot realize automatic detection of faults, and it is difficult to standardize the operation process

Manual maintenance and inspection are easily affected by subjective factors, have great uncontrollability, and there may be large errors, and failure points cannot be found in time, which affects production efficiency;

[0004] 2. The existing technical solutions can only test a single specific component of the display (such as the main control board, logic board, power supply board, backlight boost constant current board, etc.), and cannot test the whole machine including all these components , when the equipment failure is caused by simultaneous failure of multiple components, it is difficult to troubleshoot;

[0005] 3. The existing technical scheme has no partial short circuit protection and safety linkage function. When a short circuit occurs in the internal circuit of the display screen, the power supply of the entire system will be interrupted, causing other normal display screen tests to be interrupted, and data cannot be obtained, which affects the test progress; when the display screen circuit When the short circuit causes combustion and smoke, the alarm information cannot be issued in time

[0006] 4. The existing technical solutions cannot achieve uninterrupted aging test

Aging tests ranging from 24 to 27 hours are required after the equipment is repaired, and someone needs to be on duty to find problems in the testing process and solve them in time, which will greatly occupy human resources
