Description

TCMS system semi-physical simulation test platform and test method

Technical Field

The application relates to the technical field of TCMS (thyristor controlled test system), in particular to a TCMS system semi-physical simulation test platform and a test method.

Background

With the rapid development of urban rail transit in China, trains such as subways, light rails and low-land scooters are operated on a large scale, and as urban rail vehicles integrate machinery, automatic control and information processing, maintenance of train-mounted subsystems is achieved in a mode that the subsystems are manually downloaded after the trains are put in storage, and the mode wastes manpower and material resources and is low in automation degree. Thus, the intellectualization of train maintenance is a viable research direction, where the intellectualization of train network control and management systems (TCMS) is a hotspot of research.

The TCMS is used as an information communication processing core of the train, and the safety and the reliability of the TCMS are particularly important. Because of the complexity of the train network control system, the difficulty of accurately debugging the train network control system is great. Along with the development and progress of the rail transit equipment technology in China, the function development and test technology of TCMS is mastered step by step, the design period is shortened, and meanwhile, the reliability of products is ensured. The train-mounted network control system (TCMS) is used as a brain of train operation, has perfect and powerful train control functions, and is used for connecting various controllers on a train through a train communication network to control the whole train. Along with technological progress, the train network control system has more and more functions and more complex functions, and accordingly, the design and test difficulty of the train network control system is also increased. The current network control system mainly comprises a train control and monitoring function, a network communication function, a traction control function, an auxiliary control function, a brake control function, a overhaul maintenance function and the like, and is used for testing a TCMS system and mainly for examining the adaptability of an MPU to different vehicle control requirements through matching of a DDU and a RIOM through a network. The TCMS main equipment comprises a gateway, a main control unit MPU, a remote input/output unit RIOM, a display screen DDU, a traction control unit TCU, an auxiliary control unit ACU, a brake unit BCU, other control units (such as an unmanned control unit) and the like. The network control system has more equipment, and has interlocking action, and the ground association debugging difficulty is high.

In the prior art, TCMS test platforms are generally of two types, one of which is referred to as a hardware system test platform; another is called a software functional simulation test platform. The hardware system test platform focuses on system hardware integration, communication and input-output signal testing. It typically integrates all TCMS hardware such as CCU central control unit, HMI human-machine interface display, GW gateway, input output module, MVB repeater, some subsystem control units, etc. Typically the test software is not an application of the actual loading, but all underlying software (e.g., firmware, operating system) is the same as the actual loading system, so the hardware test platform can test all aspects of the hardware and communications between the network components. The software functional simulation test platform has only a small amount of TCMS hardware, such as CCU and HMI, but these two main TCMS integrated devices can load the same application software as on the train. The software test platform needs to build a simulation model of all other TCMS devices, the devices they control, and their communications, functions and behaviors. Therefore, the software test platform can test the control logic and diagnostic functions of the TCMS application software on the train, but cannot test other hardware. Currently, the TCMS system of urban rail transit is generally subjected to type test and routine test of the TCMS system on site, and under the test form, problems of the TCMS system are exposed late, so that frequent modification of software of the TCMS system on site is easy to cause.

The TCMS system semi-physical simulation test platform provided by the embodiment of the application comprises a real equipment group and a simulation equipment group which are arranged in a carriage. Specifically, in some embodiments of the present application, in order to implement a more truly restored testing environment, devices of a real device group are distributed according to the concept of a carriage; specifically, in this embodiment, the side car may be in a virtual form or a real form, and when the car is in a virtual form, the devices in the real device group only logically simulate the concept of car distribution in terms of spatial layout or wiring; when the car is in a real form, a physical car can be set, and the devices in the real device group are arranged in the physical car.

In the following description of the embodiments of the present application, the carriage may be in a virtual form or a real form, and will not be described in detail.

In some embodiments of the present application, in order to take into account cost and test effect, 4 carriages are provided in total, so that a better test effect is achieved at a lower cost. In specific implementations, for convenience of description, 4 cars are described as 1 car, 2 car, 3 car, and 4 car; specifically, the 1 car and the 4 car are two-end carriages, and the 2 car and the 3 car are middle carriages.

Please see the architecture shown in fig. 1:

the real device group comprises MVCU (Multi-function Vehicle Control Unit, multifunctional control host, MVCU for short), RIOM Remote Input/Output Module (Remote Input/Output unit, RIOM for short) and TSN (Time-Sensitive Networking, time sensitive network, TSN) switch;

The simulation equipment group directly performs data interaction with the TSN switch.

As shown in the figure, the MVCU and RIOM remote input/output units are respectively and electrically connected with the TSN switch; the RIOM remote input/output unit is connected with a drive sampling plug box.

SDP (Session Description Protocol) describes a session protocol, which is a descriptive standard for information formats that does not belong to the transport protocol itself, but can be used by other transport protocols to exchange the necessary information for media negotiation between two session entities. The SDT protocol is used here, so that the reliability of the system is ensured.

Furthermore, the ERM data recording unit and the TSN switch are respectively connected, so that the linkage of the testing process of the testing platform is further improved, and the function of the ERM data recording unit is fully exerted.

As shown in FIG. 2, MVCU redundancy tests are divided into single network MVCU redundancy tests and dual network MVCU redundancy tests:

firstly, a driver's cab key is triggered by a driver's cab to activate, the train is at zero speed, a driver's cab is simulated to link a vehicle circuit, the vehicle circuit synthesizes 1-car RIOM1 driver's cab key activation, 1-car RIOM2 driver's cab key activation, 1-car train zero speed line and 4-car train zero speed line signals to comprehensively judge 1, then the position of a 1-car driver's cab activation point is 1, the signals are sent to a laboratory simulation drive and pick-up plug box, the simulation drive and pick-up plug box sends collected level signals to a corresponding RIOM of a TCMS system, the MVCU judges that the 1-car driver is activated at the moment according to software logic, and the MVCU feeds back the 1-car driver's cab activation signals to an HMI signal system.

In the example, through the TCMS system semi-physical simulation test platform provided by the application, the cab activation logic simulation consistent with the scene is realized, and the problem that the cab cannot be activated due to the TCMS software logic processing problem on the scene can be avoided.
