Description
Technical Field
The invention relates to the technical field of automatic testing of railway equipment, in particular to an automatic testing driving engine system of high-speed rail signal equipment.
Background
The key signal equipment of the high-speed rail train control system mainly comprises an interlock (CBI), a Train Control Center (TCC), a Radio Block Center (RBC) and a temporary speed limiting server (TSRS). The software logic of the equipment is closely connected with the line station type, a large amount of data compilation is involved when software design is carried out in engineering application, and a large amount of data test and interface test work aiming at compilation data is generated in the test. In the traditional scheme, test cases are mainly manually compiled to test compiled data and interfaces, so that the test efficiency is low and the regression is not available.
The automatic test replaces manual reading of a pre-programmed test sequence through a computer software technology, automatically inputs action conditions to the tested equipment, issues the action conditions to the tested equipment to execute a test instruction, and automatically collects action results of the tested equipment and judges correctness. The automatic testing technology is introduced into the field of testing data interfaces of high-speed rail signal equipment, so that the labor intensity of testing personnel can be reduced, and the testing work efficiency is improved.
At present, the domestic and foreign tests of high-speed rail signal equipment are mainly manual tests, and partial test items of some equipment (such as CBI and TCC) realize data-driven automatic tests based on test scripts, namely, test data and the test scripts are separated, and the test data drives the test scripts to test and control a tested object. As shown in fig. 1, is a current test script-based data-driven automatic test scheme. The disadvantages of this solution are: 1) the comparison of test results is performed in the automatic test engine, resulting in a tight coupling of the automatic test engine to the test logic and poor versatility, e.g. an automatic test engine for testing a real TCC cannot be used for testing a real CBI device. 2) The logic service of the automatic test engine is too concentrated, and the calculation amount of the comparison of the test result and the number of the controlled simulation test equipment have a linear growth relationship, which is not beneficial to the load balance of the server of the automatic test engine. 3) Special communication protocols need to be designed between the automatic test engine and the simulation test equipment (simulation CBI, simulation TSRS and the like), the universality is poor, and the maintenance difficulty of the whole automatic test system is increased.

the main engine acquires test data of the background database through a database interface, packages the test data into a test task, and sends the test task to the corresponding sub-engines in a serialized flow;
