Automatic interlocking test system and automatic interlocking test method on basis of big data

Abstract

The invention provides an automatic interlocking test system and an automatic interlocking test method on the basis of big data. The automatic interlocking test system comprises an automatic interlocking test device and data acquisition devices. The data acquisition devices are arranged at various operation stations; the automatic interlocking test device comprises simulation IO (input and output)equipment, simulation command control equipment and a centralized controller; the data acquisition devices are used for acquiring working state information of interlocking systems at the corresponding operation stations; test cases for testing to-be-tested interlocking machines can be designed by the centralized controller according to the received working state information of the interlocking systems at the various operation stations, corresponding information can be inputted in the to-be-tested interlocking machines by the simulation IO equipment and the simulation command control equipmentunder the control of the centralized controller according to test contents designed in each test case, and whether output of the to-be-tested interlocking machines is consistent with target output results in the test cases or not can be detected by the centralized controller, so that the to-be-tested interlocking machines can be tested. The automatic interlocking test system and the automatic interlocking test method have the advantages that the test efficiency can be improved, and the to-be-tested machines can be completely tested.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to an interlocking automatic testing system and method based on big data. Background technique [0002] Safety is the eternal theme and the core issue of railway transportation. Only when safety is ensured can rail transport be meaningful. There are many lines in the station, and the two ends of these lines are connected by turnouts. Different approaches are formed according to the different positions of the turnouts, and whether the train can enter the approach is commanded by a signal machine. If the signal shown by the signal machine indicates that the train enters a certain track, but the opening position of the switch is to open another track, there is a danger of a traffic accident. In order to ensure safety, there must be a certain mutual restriction relationship between the signal machine, the approach and the switch. This relationship is called interlocking. ...

Problems solved by technology

R&D personnel test the normal working logic of the product, and also test some abnormal logic. However, R&D personnel do not operate the tested equipment every day after all. In other words, due to the impact of other equipment on site, the impact of operation plans, etc., the so-called "logical combination that will never appear" may be reasonable and understandable in the case of the site, which results in manual testing by R&D personnel or the so-called "Automated testing" cannot simulate all operations of field operators

At the same time, on-site operators have no way to feed back all their operations to R&D personnel

Even if a failure occurs, the R&D personnel can only analyze the failure of the equipment itself, and cannot reproduce the entire operation process of the on-site operators at that time
