Description

Technical Field

[0001] The present invention relates to the field of testing technology, and in particular to a distributed testing system and method for a maglev transportation control system. Background Art

[0002] The ultra-high-speed, low-vacuum tube maglev system is characterized by its high-speed operation within a low-vacuum tube. The system's operation and control system features a three-tiered architecture, consisting of central, zoned, and onboard control subsystems, as well as speed and communication subsystems such as positioning, speed measurement, and wireless communication.

[0003] Among them, the central operation control system is responsible for monitoring, controlling and coordinating the operation of various systems; the zone operation control system is responsible for the control, management and protection of train operation lines and trains; the on-board operation control system is responsible for monitoring the status of train on-board equipment, operation control and train protection; the positioning and speed measurement system provides the operation control system with vehicle mileage, speed, vehicle direction and other information; the vehicle-ground wireless communication system is responsible for the vehicle-ground transmission of operation control data.

[0004] Currently, maglev transportation systems are limited by the distributed nature of their operation and control systems—each vehicle and ground vehicle has its own subsystems. Testing of these systems primarily relies on online testing of the system through the coordinated commissioning of online vehicles. Offline testing methods exist, but these primarily focus on individual subsystems of the operation and control system. Existing maglev systems lack a comprehensive offline testing method for the entire operation and control system after equipment integration. Summary of the Invention

[0037] Figure 1 A block diagram of a distributed test system for a maglev transportation control system according to an embodiment of the present invention is shown, which shows the test system, the object to be tested, the auxiliary test equipment and the interface relationship.

[0038] exist Figure 1 In the figure, interface type ① is the interface between subsystems of the test system; interface type ② is the external interface of the test system; interface type ③ is the interface between subsystems of the operation and control system, where the dotted line is wireless communication; interface type ④ is the interface between the operation and control system and other subsystem equipment in the maglev transportation project (other on-board equipment, other central equipment, and other partitioned equipment).

[0039] like Figure 1As shown, an embodiment of the present invention provides a distributed testing system for a maglev transportation control system, the testing system comprising a distributed deployed vehicle-mounted testing device, a central testing device, and a partitioned testing device, wherein:

[0040] The vehicle-mounted test device includes a vehicle-mounted data acquisition module, a vehicle-mounted equipment simulator, and a vehicle motion simulator. The vehicle-mounted equipment simulator is used to simulate the operation of the vehicle-mounted operation and control circuit equipment, the vehicle-mounted motion simulator is used to simulate vehicle motion, and the vehicle-mounted data acquisition module is used to collect data from the vehicle-mounted operation and control system under test.

[0041] For example, onboard control loop equipment includes onboard positioning and speed measurement equipment, onboard power distribution equipment, control equipment for other onboard subsystems, and onboard actuation equipment. Vehicle motion includes forces and posture changes. Through simulations using onboard equipment simulators and vehicle motion simulators, the onboard control system can "sense" the online status of various onboard devices, the controlled state, and changes in the vehicle's six degrees of freedom.

[0042] The partition test device includes a position and speed simulator and a partition data acquisition module. The position and speed simulator is used to simulate the speed and position of the vehicle, and the partition data acquisition module is used to collect data of the tested partition operation control system.

[0043] That is, the input of the position and speed simulator (i.e., simulating the speed and position of the vehicle) can be used to provide sensor input for the positioning and speed measurement system (i.e., obtaining information such as the actual speed and position of the vehicle), so that the partition operation control system can "sense" the vehicle's position and speed, so that it can perform vehicle operation control and safety protection.

[0044] The central testing device includes a test main control module and a central data acquisition module. The central data acquisition module is used to collect data of the central operation control system under test. The test main control module is used to simulate the vehicle operation process and scheduling process as well as the initialization status of the line, traction, and communication equipment. The test main control module is also used to test the tested vehicle operation control system, the tested partition operation control system and the tested central operation control system based on the data collected by the on-board data acquisition module, the data collected by the partition data acquisition module and the data collected by the central data acquisition module, wherein the partition data acquisition module, the on-board data acquisition module and the central data acquisition module collect data synchronously.

[0045] That is, the central test device can use the comprehensive information of various systems such as lines, vehicles, traction, control, and communications as the simulation input of the test main control module, simulate the vehicle operation process and scheduling process, and the initialization status of lines, traction, and communication equipment, to ensure that the central operation control system can "sense" the correct operating status of other systems.

[0046] Among them, the vehicle-mounted test device and the partition test device are connected to the central test device, and the central test device completes the interface coordination between the test devices. The data collected by the vehicle-mounted data acquisition module and the data collected by the partition data acquisition module are collected in the central test device (the central test device can obtain the data collected by the vehicle-mounted data acquisition module and the partition data acquisition module).

[0047] The above technical solution enables the simulation of each of the distributed subsystems of the operation and control system, thereby achieving simulated input and output for multi-level operation and control system operations. By collecting data from each distributed subsystem, distributed testing can be implemented with the central operation and control system, the sub-regional operation and control system, and the onboard operation and control system as the front-end test objects, effectively reducing the risks of maglev vehicle operation on the line. Furthermore, a synchronous testing method is used to synchronize the collection of front-end data from the central, sub-regional, and onboard operation and control systems, ensuring data and process consistency for comprehensive testing and diagnosis.

[0048] That is, the distributed testing system described in the present invention targets the typical components of the operation and control system of the maglev transportation system, and adopts a distributed testing method of distributed simulation, synchronous acquisition, and comprehensive diagnosis, which can ensure the correctness and coordination of the comprehensive testing of the operation and control system, and effectively reduce the probability of failure in the online operation of the maglev transportation operation and control system.

[0049] According to one embodiment of the present invention, the on-board data acquisition module collects data of the on-board operation control system under test, including collecting the on-board equipment control network data constituted by the on-board operation control system; the partition data acquisition module collects data of the partition operation control system under test, including collecting the trackside equipment network data of the partition control monitoring bus; the central data acquisition module is used to collect data of the central operation control system under test, including directly collecting the server data of the central operation control system.

[0050] Among them, the time synchronization of the collected data of the three collection modules can directly use the master clock in the operation control system to synchronize the periodic control of the collection time. In order not to confuse the present invention, it will not be described here.

[0051] According to one embodiment of the present invention, the test main control module tests the tested vehicle operation control system, the tested partition operation control system, and the tested central operation control system based on the data collected by the vehicle data collection module, the data collected by the partition data collection module, and the data collected by the central data collection module, including:

[0052] The test main control module compares the data collected by the vehicle-mounted data acquisition module, the data collected by the partition data acquisition module and the data collected by the central data acquisition module with the measured historical data stored in the historical database, and tests the offline operating status of the tested vehicle-mounted operation control system, the tested partition operation control system and the tested central operation control system.

[0053] Measured historical data, for example, refers to the operational data captured by the operation control system during the last actual operation of the vehicle. By collecting data on control instructions, actuation responses, and status monitoring from the vehicle-mounted, central, and sub-area operation control systems to other subsystem devices, and comparing it with the measured historical data in the historical database, the offline operational status of the operation control system can be tested and verified.

[0054] For example, if the comparison result meets the requirements, the test verification passes, otherwise the test verification fails.

[0055] According to an embodiment of the present invention, the test main control module tests the tested vehicle operation control system, the tested partition operation control system, and the tested central operation control system based on the data collected by the vehicle data collection module, the data collected by the partition data collection module, and the data collected by the central data collection module, further comprising:

[0056] The test main control module extracts and preprocesses the data collected by the vehicle-mounted data acquisition module, the data collected by the partition data acquisition module and the data collected by the central data acquisition module, and compares the preprocessed data with the predetermined communication protocol to test the system internal control and feedback data between the tested vehicle-mounted operation control system, the tested partition operation control system and the tested central operation control system.

[0057] In this way, the correctness and consistency of the internal control logic and interface communication of the operation and control system can be directly verified.

[0058] For example, if the comparison result meets the requirements, the test passes, otherwise the test fails.

[0059] According to one embodiment of the present invention, the test main control module is also used to simulate equipment failures, and to test the consistency and logical relationship of the protection control functions of the tested vehicle-mounted operation control system, the tested partitioned operation control system and the tested central operation control system in the presence of equipment failures.

[0060] That is, through the fault simulation of the simulation equipment provided by the test system, the safety protection function of the operation and control system when equipment failure occurs can be stimulated, and then the consistency and logical relationship of the protection control functions of different levels (for example, the levels of central, partition and vehicle-mounted) and different authorities of the central operation and control system, partition operation and control system, and vehicle-mounted operation and control system can be verified.

[0061] In general, using the comprehensive comparison results of measured data and historical data, and the consistency test results under fault isolation as the results of distributed testing can meet the testing requirements of distributed operation and control systems.

[0062] According to one embodiment of the present invention, the test main control module is also used to perform comprehensive diagnosis of test data based on offline operation status test results, system internal control and feedback data test results, and consistency and logical relationship test results of protection control functions.

[0063] The specific comprehensive diagnosis method can adopt the existing methods in the prior art, and the present invention is not limited to this.

[0064] Through comprehensive diagnostic testing, distributed comprehensive testing can be performed on the distributed operation and control system to ensure the correctness and completeness of the functional interface testing of the operation and control system.

[0065] Figure 2 Shown Figure 1 A test system executes a running logic diagram of a distributed test method.

[0066] like Figure 2 As shown, an embodiment of the present invention provides a distributed testing method for a maglev transportation control system, wherein the testing method includes:

[0067] The on-board equipment simulator of the on-board test device simulates the operation of the on-board operation control loop equipment, and the on-board motion simulator of the on-board test device simulates the motion of the vehicle;

[0068] That is, the vehicle equipment simulator simulates the main functions of the vehicle equipment, acts as the controlled object of the vehicle operation control system, and communicates with the vehicle operation control system. Figure 2 (1) in the vehicle motion simulator simulates the vehicle motion posture simulation, which serves as the perception input of the vehicle operation control system and responds to the control logic of the vehicle operation control system. Figure 2 (2) in .

[0069] The position speed simulator of the partition test device simulates the speed and position of the vehicle;

[0070] That is, the sensor input of the simulation positioning speed measurement system is used to stimulate the positioning speed measurement system to generate position and speed signals, corresponding to Figure 2 (4) in .

[0071] The test master control module of the central test device simulates the vehicle operation process and dispatch process as well as the initialization status of the line, traction and communication equipment;

[0072] That is, the operation scenario of the maglev transportation control system is simulated as the process simulation of the driving control of the central operation control system, corresponding to Figure 2 (3) in .

[0073] The vehicle-mounted data acquisition module of the vehicle-mounted test device collects data of the vehicle-mounted operation control system under test;

[0074] That is, data is collected from the vehicle-mounted operation control bus network, such as control instructions, vehicle-mounted equipment controlled execution data, etc. Figure 2 (5) in;

[0075] The partition data acquisition module of the partition test device collects data of the tested partition operation and control system;

[0076] That is, data is collected from the control monitoring bus of the zone operation control system, such as control instructions and response data of the zone operation control system and other systems in the maglev transportation system such as the traction system, etc. Figure 2 (7) in.

[0077] The central data acquisition module of the central test device collects data from the central operation and control system under test;

[0078] That is, data is collected from the server of the central operation control system, such as the control instructions and response data of the partition operation control system and the vehicle operation control system, corresponding to Figure 2 (6) in.

[0079] The test main control module tests the tested vehicle-mounted operation control system, the tested partitioned operation control system and the tested central operation control system based on the data collected by the vehicle-mounted data acquisition module, the data collected by the partitioned data acquisition module and the data collected by the central data acquisition module, wherein the vehicle-mounted test device, the central test device and the partitioned test device are deployed in a distributed manner, and the partitioned data acquisition module, the vehicle-mounted data acquisition module and the central data acquisition module collect data synchronously.

[0080] The above technical solution enables the simulation of each of the distributed subsystems of the operation and control system, thereby achieving simulated input and output for multi-level operation and control system operations. By collecting data from each distributed subsystem, distributed testing can be implemented with the central operation and control system, the sub-regional operation and control system, and the onboard operation and control system as the front-end test objects, effectively reducing the risks of maglev vehicle operation on the line. Furthermore, a synchronous testing method is used to synchronize the collection of front-end data from the central, sub-regional, and onboard operation and control systems, ensuring data and process consistency for comprehensive testing and diagnosis.

[0081] Those skilled in the art should understand that Figure 2The serial numbers are merely exemplary and are not intended to limit the order of the steps.

[0082] According to one embodiment of the present invention, the test main control module tests the tested vehicle operation control system, the tested partition operation control system, and the tested central operation control system based on the data collected by the vehicle data collection module, the data collected by the partition data collection module, and the data collected by the central data collection module, including:

[0083] The test main control module compares the data collected by the vehicle-mounted data acquisition module, the data collected by the partition data acquisition module and the data collected by the central data acquisition module with the measured historical data stored in the historical database, and tests the offline operating status of the tested vehicle-mounted operation control system, the tested partition operation control system and the tested central operation control system.

[0084] That is, the data collected by the central, sub-regional and vehicle-mounted systems are compared and analyzed with the measured historical data in the historical database. Figure 2 (8) in.

[0085] According to an embodiment of the present invention, the test main control module tests the tested vehicle operation control system, the tested partition operation control system, and the tested central operation control system based on the data collected by the vehicle data collection module, the data collected by the partition data collection module, and the data collected by the central data collection module, further comprising:

[0086] The test main control module extracts and preprocesses the data collected by the vehicle-mounted data acquisition module, the data collected by the partition data acquisition module and the data collected by the central data acquisition module, and compares the preprocessed data with the predetermined communication protocol to test the system internal control and feedback data between the tested vehicle-mounted operation control system, the tested partition operation control system and the tested central operation control system.

[0087] That is, synchronous diagnosis of communication data between operation and control systems, such as timing relationship and operation process, corresponding Figure 2 (9) in.

[0088] According to one embodiment of the present invention, the method further includes: the test main control module performs equipment failure simulation, and tests the consistency and logical relationship of the protection control functions of the tested vehicle-mounted operation control system, the tested partitioned operation control system and the tested central operation control system in the presence of an equipment failure.

[0090] According to one embodiment of the present invention, the method further includes: the test main control module performs comprehensive diagnosis of test data based on offline operation status test results, system internal control and feedback data test results, and consistency and logical relationship test results of protection control functions.

[0091] That is, a comprehensive diagnostic test is conducted by combining the test data comparison test results, the data synchronization diagnostic test results between the operation and control systems, and the fault isolation data consistency test results. Figure 2 (10) in.

[0092] Figure 2 The method described Figure 1 The system described corresponds to the specific examples. Figure 1 The description of the system will not be repeated here.

[0093] It can be seen from the above embodiments that the above-mentioned test system and method of the present invention can carry out distributed testing with the central operation control system, the partitioned operation control system, and the vehicle-mounted operation control system as the front-end of the test object. Such distributed testing can reduce the pressure of online joint debugging and testing caused by insufficient offline verification of the control and protection functions of the operation control system, and effectively reduce the risk of online operation of maglev vehicles.

[0094] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0095] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0096] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0097] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
