Description

Technical Field

[0001] The utility model relates to an intelligent comprehensive testing system based on railway wireless shunting light display equipment, belonging to the technical field of railway shunting operation equipment maintenance and repair. Background Art

[0002] With the continuous improvement of the technical content and technical level of on-site equipment, equipment technology no longer simply involves one or two scientific and technological knowledge as in the past, but may involve more and more complex scientific and technological knowledge. At present, the maintenance of wireless communication equipment is rather awkward, mainly manifested in the following aspects: maintenance personnel only have wireless comprehensive testers, but no corresponding matching horizontal adjustment equipment and test software. Some returned equipment is unstable and repeatedly returned for repair by the railway transportation user department. After accepting the equipment, the maintenance department can only conduct simple manual experiments and tests. The test results are often normal, but similar faults occur again when it is returned to the site for use. When the maintenance department uses a digital comprehensive tester for maintenance, it can only test the call bit error rate and other conventional power, frequency error and other indicators, but cannot judge the digital signaling bit error rate. There is a lack of test methods to simulate on-site use conditions, such as: automatic cycle test of equipment transmission and reception; N-time cycle test of single or all shunting instructions; make maintenance method judgments based on test results and correctly replace panels. The maintenance department needs to spend a lot of money to repeatedly purchase equipment from manufacturers to build maintenance simulation test equipment. There is no basis for judging the maintenance test results, and the maintenance personnel are very worried. The railway wireless shunting equipment has completed the upgrade from analog to digital, and the traditional analog maintenance method can no longer adapt to the current technological development. With the development of digital information technology of railway transportation equipment, it is particularly important to develop a new intelligent comprehensive test system based on railway wireless shunting lighting equipment to provide railway communication maintenance departments with efficient, reliable and convenient means of railway wireless shunting lighting equipment maintenance, ensure that the faults of the returned equipment can be quickly and accurately located and repaired, shorten the equipment maintenance cycle and ensure the safe operation of the equipment.

[0079] The test of the electrical performance of the conventional railway wireless shunting light display device 100 mainly consists of two steps: transmitter test and receiver test. The test method and principle are summarized as follows: Transmitter test: The human-computer interaction and display unit 400 operates the transmitter of the conventional railway wireless shunting light display device 100 to transmit the DMR signal, which is received and analyzed by the digital wireless comprehensive tester unit 200. Thereafter, the corresponding numerical test results are read on the screen of the human-computer interaction and display unit 400 or the digital wireless comprehensive tester unit 200.

The utility model is used for the maintenance and inspection tasks of shunting equipment in the station yard. Conventional railway wireless shunting light display equipment is mainly composed of three main devices: machine controller, district chief desk, and handheld desk.

The three simulation functions of "having the function of establishing a simulated machine controller, having the function of establishing a simulated handheld station, and having the function of establishing a simulated district chief station" avoid the embarrassment of setting up a test environment when repairing equipment due to the lack of spare equipment. The system information collection has electrical and communication isolation measures, which does not affect the normal operation of the existing horizontal shunting equipment in the station. It adopts a humanized design and has a large expandable space.
