Description
Technical field
The present invention relates to the rail traffic signal system technical field of measurement and test, relate to a kind of on-board running control system method of testing and system based on data-driven, particularly a kind of can be to rail transportation vehicle-mounted operation control system implement the to interconnect general method of testing and the system of test, functional test and performance test.
Background technology
Along with the fast development of Chinese Rail Transit System, train running speed is more and more higher, and the train departure interval is more and more closeer.The high speed of Rail Transit System and high density characteristics are also had higher requirement to ensureing train traffic safety.Train operation control system is the visual plant that is used to ensure train traffic safety in the Rail Transit System.Train operation control system is by detecting train physical location and line status in real time, comprehensive various factors calculates the maximum safe operation speed of train in real time, and real-time oversight train actual motion speed, implement overspeed protection, thereby guarantee that train moves under the running interval of the speed of safety and safety.Train operation control system generally by control center's equipment, trackside signal facility, car information transmission equipment, on-board running control system etc. form.Wherein, the on-board running control system is equipped ON TRAINS, directly detects the state of train and can directly export the brake regulation train operation, is the key link of implementing the overspeed protection function, and is most important in whole train operation control system.In addition, Rail Transit System is as the high capacity public transportation system, and the system failure tends to cause great life, property loss.Therefore, Rail Transit System belongs to the overcritical system of safety.
Modern security of system theory requires safety technique and realizes in design, exploitation, test and the utilization maintenance process of total system, just taking into account system safety problem in whole safe life cycle.At present, the development of China's track traffic operation control system presents the characteristics of standardization and architecture, has formulated the series of standards standard, is used to instruct the design and development of peace treaty bundle train operation system, has ensured the security of system effectively.But, the test of dispatching from the factory that still mainly depends on device fabrication manufacturer self at the functional test and the safety test of system.The many design documents of the test of device fabrication manufacturer based on self, the method for testing of different vendor and means may be distinguished to some extent, and what can't guarantee to test is comprehensive.In addition, device fabrication manufacturer may exist the minority clause of system standard and user's request to be misread, and perhaps considers concealment partial test result for interests, also can't thoroughly guarantee the authority of testing.Therefore, only rely on the test of device fabrication manufacturer nonstandardized technique, there is potential safety hazard in system employs.Setting up standardized method of testing, is to solve the comprehensive and authoritative effective means of test.
On the other hand, the operator of some Rail Transit System wishes to set up an opening, standardized Rail Transit System.That is to say,, can in Rail Transit System, equip use as long as satisfy the train operation control system equipment of the standard that operator formulates; Same category of device between the different vendor can be replaced mutually, rather than must the whole total system that adopts a certain manufacturer.Open, standardized system can break up monopoly, and introduces competition, reduces system cost and maintenance cost, helps the sound development of whole rail traffic.But simultaneously also train operation control system has been proposed the requirement of interconnecting, that is to say, should possess the information of intercoursing between the equipment of different vendor and use the ability of institute's exchange message, worked in coordination and finish the total system function, possessed interoperability.Set up standardized system detection method, system is carried out standardized test, not only can avoid cross-beta between the too much manufacturer, reduce testing time, and have the test authority, and help solving the dispute between the different vendor, promote the standardized process of Rail Transit System.
In addition, method of testing is comprised configurable and requirement such as can change flexibly toward contact, as: it is adaptive to finish interface rapidly, and different systems under test (SUT) are tested; When system requirements and design generation change, can generate the dependence test case rapidly, carry out test fast.Adopt the method for data-driven to set up the standardized system method of testing, can method of testing be configured according to the characteristics of system under test (SUT), finish fast and system under test (SUT) between interface adaptive.According to the system testing demand, configuration testing case and cycle tests carry out system testing fast.
