Device and method for CIR comprehensive diagnosis test

Abstract

The invention discloses a device and a method for a CIR comprehensive diagnosis test. The device comprises an industrial personal computer 3, an interface unit 4, a power source unit 7, a human-computer interaction device and at least two test modules. Each test module is in data connection with the industrial personal computer 3 through a data interface. The interface unit 4 is in data connection with the industrial personal computer 3 through a data interface. The human-computer interaction device is in data connection with the industrial personal computer 3. The method comprises the steps: a test mode and a corresponding test parameter are set; test data are read from a general-purpose tester or the test modules; a standard value required when an index is operated normally is read from a data bank of the industrial personal computer; whether a test value is qualified or not is judged; whether all indexes or functions are tested or not is judged; and the test is finished. According to the device and the method for the CIR comprehensive diagnosis test, the test and a function experiment platform are integrated, the test of electric performance of a (CIR) 450M module, a 800M module, a GSM-R data module and a GSM-R voice module of a comprehensive wireless communication device of a vehicle and an experiment of functions of a train tail, LBJ and TAX are achieved.

Description

[technical field] [0001] The invention relates to the field of integrated wireless communication of railway locomotives, in particular to a comprehensive diagnostic testing device and method for integrated wireless communication equipment (CIR) of railway locomotives. [Background technique] [0002] In recent years, with the continuous construction and use of China's railway GSM-R communication network in railways, GSM-R communication has become an important means of railway transportation dispatching communication and train control, and has played an increasingly important role in railway transportation. effect. Locomotive integrated wireless communication equipment (CIR), as the on-board communication terminal of the GSM-R system, is also installed in large numbers on railway locomotives. [0003] Such as figure 1 As shown, the existing locomotive integrated wireless communication equipment (CIR) includes the CIR host, and the TAX unit (locomotive safety information comp...

AI Technical Summary

Problems solved by technology

Therefore, when used for functional tests, it cannot achieve the simulation coverage of all functions, and the operation is very limited.

Due to the limitations of testing equipment, there are three shortcomings in the existing testing methods. First, the testers need to master the testing principles, instrument operation methods, and the operation methods of the equipment under test. The complexity is relatively high, and the training period required is also long; Because of the limitation of the equipment, only a single channel unit can be tested each time, the process of completing the test is relatively long, and the operation is relatively complicated. The strength indicator of the signal completes the test

[0005] With the popularization of the use of CIR, how to improve the level of maintenance and repair on site and shorten the time for troubleshooting has become the main problem restricting the use of CIR
