As the direct carrier of passenger transportation in the fully automatic operation system, the vehicle system is a key system to ensure safe operation and provide comfortable and complete riding operation services. Compared with traditional manned trains, fully automatic operation trains need to have a higher degree of automation, with more comprehensive status monitoring, remote control, and safety linkage functions. During operation, under the comprehensive guarantee of systems such as the integrated monitoring system, power supply system, platform screen door system, and intelligent operation and maintenance, the fully automatic operation trains realize safe train tracking and fully automatic operation according to the train operation control instructions of the signal system.

Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0030] As Figure 1 shown, it is a structural schematic diagram of a multi - vehicle simulation platform for fully automatic operation trains in rail transit disclosed by the present invention. The platform may include: a hardware - in - the - loop train vehicle electrical simulation unit, a virtual train group vehicle electrical simulation unit, a train operation simulation unit, an on - vehicle signal system simulation unit, and a data packet disassembling and assembling server; where:

[0031] The hardware-in-the-loop train vehicle electrical simulation unit consists of a key physical system and a vehicle electrical simulation model, providing a complete human-computer interaction function during the simulation process, and realizing the linkage response test and display of the fully automatic operation vehicle system; the virtual train group vehicle electrical simulation unit has an independent vehicle electrical system function simulation unit, which, together with the hardware-in-the-loop train vehicle electrical simulation unit, provides the multi-train tracking operation test function for the entire platform; the train operation simulation unit provides independent dynamic simulation for each train in the entire vehicle system; the on-vehicle signal system simulation unit provides separate train operation monitoring, protection, and train operation control for each train; data interaction is carried out among the hardware-in-the-loop train vehicle electrical simulation unit, the virtual train group vehicle electrical simulation unit, the train operation simulation unit, and the on-vehicle signal system simulation unit based on Ethernet communication, and the data packet assembling and disassembling server provides high-speed data combination, disassembly, and distribution services for the hardware-in-the-loop train vehicle electrical simulation unit, the virtual train group vehicle electrical simulation unit, the train operation simulation unit, and the on-vehicle signal system simulation unit.

[0032] In summary, in the above embodiments, a multi-train simulation platform combining a key physical system and a functional model based on Ethernet communication is constructed. While providing high-speed communication for multi-train simulation, it not only ensures the authenticity and accuracy of system simulation, but also ensures the convenience of establishing and expanding the functional model; the vehicle electrical control function of the train and the train operation dynamics simulation are respectively simulated. Each train has an independent vehicle electrical system and train dynamic operation simulation, enabling each train to have the simulation ability to realize the train-level functions and dynamic operation of fully automatic operation vehicles; the vehicle electrical system of one train is composed of a physical system plus a functional simulation of the vehicle electrical subsystem, with complete train systems or key functional elements, providing a technology development and verification platform for the key systems of fully automatic operation vehicles. At the same time, it ensures the authenticity, observability, and operability of the vehicle system's fully automatic operation function linkage test; the vehicle electrical systems of the remaining trains are simulated using independent vehicle electrical subsystem functions, forming a virtual train group vehicle electrical simulation unit, integrating N virtual vehicles, and the specific number of virtual vehicles can be configured according to the number of trains on the actual line, and together with the physical vehicles, it realizes the ability of the system to perform multi-train tracking operation simulation; the model constructed by the train operation simulation supports the modification of line data, so that the system can be used for simulation tests on different lines.

[0033] Specifically, as Figure 2 shown, the hardware-in-the-loop train vehicle electrical simulation unit includes two major functional units: hardware-in-the-loop vehicle electrical simulation and train operation simulation, and data interaction is carried out based on Ethernet through the data packet assembling and disassembling server.

[0034] Among them, the hardware-in-the-loop train consists of the physical part of the vehicle electrical system, including: train network control system, on-vehicle information monitoring system, on-vehicle passenger information system, first signal conditioning unit, second signal conditioning unit, driver's driving simulation console, and vehicle electrical simulation function model. Among them, the vehicle electrical simulation function model provides the function model of the vehicle electrical system except for the physical system, including: logic circuit, auxiliary inverter function model, traction control system function model, brake control system function model, lighting control system function model, door control unit function model, air conditioning system function model, smoke alarm system function model, obstacle and derailment detection system function model, and high-voltage power receiving device control model. The internal communication mechanism of the physical system is the same as that of the actual on-vehicle equipment. The train network control system, on-vehicle information monitoring system, and on-vehicle passenger information system communicate through a communication bus. Among them, the communication can be an MVB bus or an Ethernet bus; the first signal conditioning unit is responsible for data interaction conversion between the vehicle electrical simulation function model and the physical train network control system, and the driver's driving simulation console simulates the real driver's cab console.

[0035] Among them, the train network control system adopts the same configuration form as the on-vehicle physical equipment, transmits instructions to each vehicle electrical subsystem (such as traction / brake, door control, air conditioning control, lighting, etc.) according to the requirements of the on-vehicle signal system, and collects the operation status and fault information of each subsystem in real time, and reports to the ground command and control center through the on-vehicle signal system; the train network control system also completes the train network logic control function.

[0036] The on-vehicle passenger information system includes four parts: on-vehicle public address device (PA), on-vehicle passenger information display device (PIDS), on-vehicle video surveillance device (CCTV), and passenger emergency call device. The on-vehicle passenger information system is an important electrical subsystem for fully automatic operation. According to the relevant scenarios of fully automatic operation, it completes the necessary functions and linkages of PA, PIDS, and CCTV, provides the function of information interaction between the control center and passengers. On the one hand, it provides services such as station announcements, emergency broadcasts, emergency calls, and travel guidance for passengers, and on the other hand, it provides a video surveillance function for the control center to timely understand the situation of the passenger compartments of remote vehicles, ensuring the correct guidance of passengers and the evacuation of emergency situations in special cases.

[0037] The on-vehicle information monitoring system is an on-vehicle device of the intelligent operation and maintenance system, responsible for collecting vehicle real-time data and offline files, covering multiple aspects such as traction, braking, auxiliary systems, doors, passenger information, air conditioning, network, and running gear; realizing the fusion and processing of vehicle data, based on the data, combined with the vehicle logic, preprocessing the data, and realizing the identification and early warning of faults as well as the traceability and analysis of fault data.

[0038] The driver's driving simulation console mimics the real driver's cab operation console to issue driver operation instructions. The simulation control elements include: control switches, bypass switches, driver's cab driver controllers (including signals such as keys, forward, backward, traction, braking, and handle positions), and the action switch of the driver's console cover. The second signal conditioning unit serves as the communication bridge between the driver's driving simulation console and the vehicle electrical simulation functional model. It receives the digital input signals from the driver's console buttons and the handle position signals, converts them into Ethernet protocol data, and transmits it to the vehicle electrical simulation functional model. Conversely, it converts the status data from the vehicle electrical simulation functional model into digital input signals and transmits them to the control status indicator lights on the driver's console.

[0039] The first signal conditioning unit consists of two parts: a bus communication unit (which can be MVB or Ethernet) and an IO unit. As the communication bridge between the vehicle electrical simulation unit of the semi-physical vehicle and the train network control system, it is connected to the vehicle electrical simulation functional model through Ethernet and has a hardwired connection and a communication bus connection with the train network control unit. Taking the MVB communication bus as an example for its function description, the first signal conditioning unit receives the Ethernet protocol data from the vehicle electrical simulation functional model, splits it into MVB data communication packets and IO hardwired information transmission packets. The MVB communication packets pass through the data conversion module, convert the Ethernet protocol into the MVB protocol, and send it into the vehicle network. The IO hardwired information is converted into voltage switch signals and sent to the IO interface of the train control network chassis. Conversely, it groups the MVB data and IO hardwired data received from the vehicle network and transmits them to the vehicle electrical simulation functional model. This ensures the consistency and integrity of the real device interfaces in the vehicle network and the actual train device interfaces.

[0040] The function distribution of the vehicle electrical simulation functional module is as follows: The logic circuit realizes functions such as the control of the train's hardwired traction logic circuit, the power distribution and management of the electrical subsystem control power supply, the safety loop function, the control circuits of electrical subsystems (current collectors, doors, air conditioners, lighting, etc.), isolation and bypass circuits, and remote reset simulation. The traction simulation control system functional model executes functions such as the main circuit logic control of the train's traction, electric braking control, and simulation control of wheel spin / slide protection. The braking simulation control system functional model executes the air braking control of the train and completes functions such as the simulation of the train's service braking, emergency braking, rapid braking, holding braking, and parking braking. The door control unit functional model mainly realizes functions such as the control of all the train's doors, door status monitoring, and fault simulation. The air conditioning system functional model mainly realizes functions such as the control of all the train's air conditioners, status monitoring, and fault simulation. The lighting control system functional model mainly realizes functions such as the control of all the train's lighting, status monitoring, and fault simulation. Other simulations include: train load simulation, simulation of derailment and obstacle detection actions of the obstacle and derailment detection system functional model, and simulation of high-voltage current collection control of the high-voltage power receiving device control model.

[0041] In addition to simulating the vehicle electrical function model, the hardware-in-the-loop vehicle electrical simulation function model is also equipped with a vehicle action and fault injection model, which can inject fault information into the simulation function model, including: train: logic circuit, traction control system, braking control system, door control system, air conditioning control system, lighting system, smoke alarm system, derailment and obstacle detection action simulation; thus simulating various abnormal and emergency states of the vehicle and triggering the linkage functions of different scenarios.

[0042] Specifically, as Figure 3 shown, in the vehicle electrical simulation unit of the virtual train group, each train has an independent vehicle electrical system and a train operation simulation module. The electrical system consists of: a train network control system model, a driving simulation console (driver's cab console interface, vehicle key status display interface), and system function models consistent with the hardware-in-the-loop vehicle, including: logic circuit, auxiliary power system function model, traction system function model, braking system function model, lighting system function model, door control unit function model, air conditioning system function model, smoke alarm system function model, obstacle and derailment detection system function model, high-voltage power receiving device control model. The virtual vehicle supports single-vehicle driving control and, together with the hardware-in-the-loop vehicle, provides a multi-train tracking operation test function for the entire system.

[0043] Specifically, as Figure 4 shown, the train operation simulation unit consists of a traction / braking characteristic model, a running resistance model, a wheel-rail model, a kinematic model, and a line model. According to the train's traction and braking levels, speed, and network voltage, combined with the basic line data, it calculates the train's traction / braking force, speed, acceleration, running mileage, traction / braking power, etc., simulating the running process of train vehicles on the line that meets the requirements of full-automatic driving, and providing data input for the vehicle electrical simulation system and the signal simulation system. The train operation simulation unit is built on a real-time high-precision simulation platform and communicates with the vehicle electrical and on-vehicle signal systems through Ethernet communication to ensure the real-time and accuracy of speed calculation during multi-train dynamics calculation simulation. Among them, the basic line data refers to the basic line data and basic operation organization data, including information such as lines, stations, ramps, curves, speed limits, signal lights, kilometer marks, axle counters, etc. The basic line data can be edited, modified, and replaced to achieve the running simulation of different lines.

[0044] Specifically, as Figure 5 shown, the on-vehicle signal system simulation unit provides an independent on-vehicle signal system function module for each train, independently monitors, protects, and controls the running state of each train, sends control instructions to the vehicle electrical and train operation simulation function modules through the data packet unpacking server, and receives the status information from the vehicle electrical and the speed, power, etc. information from the train operation simulation unit.

[0045] In summary, the present invention meets the new requirements and higher requirements of GOA4 (Grade of Automation 4, the grade of urban rail transit automation, in which the system realizes automatic train operation without manned operation), and constructs a test platform to support the function and performance verification of FAO (Fully Automatic Operation) vehicles: Based on the computer network, a multi-train simulation system composed of one semi-physical train and N virtual trains is constructed, which supports the multi-train tracking control operation simulation and test of the fully automatic operation system; by modifying and replacing the line basic data in the train operation simulation unit, the platform can be applied to the vehicle operation simulation of different lines; the vehicle simulation platform adopts a modular design, which is convenient for upgrading and expansion, and can support the linkage interaction with other systems.

[0046] On the basis of meeting the functional and performance requirements of FAO trains, a single-train simulation and test platform for fully automatic operation trains with the design concept of combining "virtual" and "real" is established to maximize the system's minimum functions: The simulated train integrates vehicle electrical simulation and running dynamics simulation to realize the comprehensive simulation of the train-level functions and train operation of fully automatic operation vehicles; the semi-physical train combines key physical systems with simulation function models to provide complete human-computer interaction functions and support the comprehensive test and display of the linkage response functions of fully automatic operation vehicle systems; the modular design of subsystem functions facilitates the use and replacement of physical systems, providing a reliable test and verification platform for vehicle function technology research.
