Technical Field

[0001] The present invention relates to the technical field of battery swap stations, and in particular to a virtual simulation platform for battery swap station equipment. Background Art

[0002] In the operation of battery swap stations, the stability and functionality of the software system are crucial. Traditionally, the release and verification of battery swap station software versions rely on the hardware equipment of the actual battery swap station, including PLC equipment, chargers, auxiliary equipment, etc. Although this method can ensure the performance of the software in a real environment, it also has a series of defects and shortcomings:

[0003] 1. High resource dependence: Reliance on actual hardware devices means that a large number of hardware resources need to be coordinated and configured during the software verification process. This includes ensuring that all devices are available and making necessary configuration adjustments based on verification requirements. The preparation, configuration, and coordination of hardware resources usually takes a lot of time and may cause delays in the debugging and verification process.

[0004] 2. High cost: The cost of software verification in actual battery swap stations includes not only the purchase, maintenance and update costs of the equipment itself, but also indirect costs such as labor costs and time costs.

[0005] 3. Environmental constraints: When verifying in a real battery swap station environment, external factors (such as equipment failure, environmental factor changes, human operation errors, etc.) may interfere with the verification results, resulting in instability of the test results.

[0006] 4. Lack of flexibility: For compatibility testing of various types of battery swap stations, traditional methods require multiple deployments and adjustments of actual equipment to adapt to the configuration and interface requirements of different equipment.

[0028] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings so that those skilled in the art can easily implement the present invention. The present invention can be embodied in many different forms and is not limited to the embodiments described herein.

[0029] like Figure 1 A structural schematic diagram of a virtual simulation platform for battery swap station equipment in an embodiment of the present invention is shown.

[0030] The station control system is the core part of the battery swap station. It coordinates the entire battery swap process and performs battery swap control. The station control system of the battery swap station is deployed in the battery swap station and has functions such as battery swap monitoring, charging monitoring, vehicle management, electricity metering, data statistics, etc., to achieve logical control and operation and maintenance monitoring of the battery swap process. The platform establishes a connection with the station control system through a reliable communication protocol and interface;

[0031] The platform includes:

[0032] Multiple equipment virtual simulation modules; each equipment virtual simulation module simulates a specific peripheral device in the battery swap station; each module is embedded with business logic that matches the business functions of the corresponding peripheral device. These business logics are designed based on the actual working principles and business processes of the equipment, and can monitor and control the relevant business of the battery swap station in real time in a virtual environment to ensure the authenticity and effectiveness of the simulation.

[0033] In order to improve the maintainability and scalability of the platform, the business logic built into all device virtual simulation modules adopts a unified code architecture design. This design not only simplifies the interaction between modules, but also reduces the complexity of system upgrades and maintenance.

[0034] When there is a need for software verification of a battery swap station, the platform can select and activate one or more equipment virtual simulation modules according to actual needs. These modules will use the built-in business logic to perform corresponding business processing and generate necessary test data. Subsequently, these test data will be sent to the station control system for further analysis and verification.

[0035] Therefore, the present invention effectively gets rid of the dependence on physical devices by virtualizing peripheral devices, improves software verification efficiency and flexibility, adopts a unified code architecture to comprehensively simulate battery swap station business scenarios, reduces costs and time, and accelerates software iteration. At the same time, it ensures the reliability of verification results by precisely controlling the virtual environment, and provides a highly scalable solution that is widely compatible with a variety of battery swap stations and equipment, greatly enhancing the flexibility and adaptability of the system.

[0036] In one embodiment, in the device virtual simulation module, corresponding virtual device modules are designed for each communication protocol supported by each peripheral device. These virtual device modules are the key parts of simulating peripheral devices. They realize communication with the station control system and simulation of device functions through the communication interface and function modules of the simulated device.

[0037] Each virtual device module includes: a communication interface and a functional module.

[0038] The communication interface is designed based on the communication parameters set by the corresponding communication protocol. These communication parameters ensure that the virtual device module can communicate with the station control system using the corresponding communication protocol.

[0039] Functional modules are designed based on the set device parameters. These device parameters determine the device functions and behaviors that the virtual device module can simulate. The main function of the functional module is to simulate all the functions of the peripheral device. It calls the corresponding algorithm or logic based on the received instructions or data to generate virtual device responses or data. These responses or data can accurately reflect the actual working status and performance of the peripheral device, thereby achieving a comprehensive simulation of the device functions and achieving efficient software verification.

[0040] In one embodiment, in order to simplify the interaction between the device virtual simulation module and the station control system, each communication interface of the device virtual simulation module is standardized. The standardized design ensures that different devices can communicate using a unified communication protocol and data format. This greatly reduces the problems caused by incompatible communications between devices, allowing the device virtual simulation modules of various peripheral devices to be easily connected to the station control system to achieve seamless data exchange. For developers, standardized communication interfaces mean that they do not need to write complex communication code separately for the device virtual simulation module of each device. Instead, they can use a unified interface standard to develop communication modules for peripheral devices, which significantly reduces development costs and time, making system integration more efficient.

[0041] In one embodiment, the types of communication protocols include: TCP (Transmission Control Protocol), CAN (Controller Area Network), Modbus, RS485, IO (Input / Output), MQTT (Message Queuing Telemetry Transport, a lightweight message transmission based on publish / subscribe mode) protocol, HTTP (HyperText Transfer Protocol) and Redis protocol.

[0042] TCP is the Transmission Control Protocol, which is a connection-oriented, reliable, byte-stream-based transport layer communication protocol. CAN is a serial communication protocol, mainly used in fields such as industrial automation and vehicle networks. Modbus is an open serial communication protocol with a master-slave architecture. Modbus supports a variety of electrical interfaces, such as RS-232, RS-485, etc., and can also be transmitted on various media. There are three types of Modbus protocols: Modbus ASCII, Modbus RTU, and Modbus TCP / IP. RS-485 is a serial communication standard for differential signal transmission, which is widely used in industrial automation, remote monitoring and other fields. IO is a general-purpose computer interface. In the communication protocol, IO usually refers to the interface for transmitting data between devices or between devices and computers. The IO interface can be a physical interface (such as USB, serial port, etc.) or a software interface (such as network sockets, etc.). MQTT is a lightweight message transmission protocol based on the publish / subscribe model. It is designed for small devices, low bandwidth, unreliable or high-latency networks. The MQTT protocol achieves low-overhead and high-efficiency communication between devices through a simple message format and flexible communication mode. HTTP is an application layer protocol used to transmit data on the Web. The Redis protocol is the communication protocol used by the Redis database for data exchange between the client and the server.

[0043] It should be noted that if the CAN bus protocol is used, a CAN transceiver is required to connect the device virtual simulation module to the CAN bus.

[0044] In one embodiment, the communication parameters include: communication rate and data frame format; the communication rate, i.e., the rate of data transmission, is usually measured in bits per second (bps). The communication rate determines the speed and efficiency of data transmission. The data frame is the basic transmission unit in network communication, and the data frame format specifies the organizational structure of data during transmission. The correct data frame format can ensure the correct transmission and parsing of data.

[0045] The device parameters include: simulated virtual device type and virtual device function realization parameters. The simulated virtual device type refers to the peripheral device type of the battery swap station simulated by software. For example, PLC devices, chargers, auxiliary equipment, etc. The peripheral device function realization parameters are parameters used to describe and realize the specific functions of virtual peripheral devices. The selection and configuration of these parameters directly affect the performance and function realization of the virtual device.

[0046] In one embodiment, the functional modules include:

[0047] The monitoring module is used to monitor the relevant key parameters and fault status of the corresponding peripheral equipment in real time; analyze the relevant key parameters to determine whether they are within the normal range. If not, fault information is generated and sent to the station control system through the communication interface to alarm.

[0048] The business logic module is used to perform corresponding business processing based on the business logic of the corresponding peripheral device and generate corresponding business data;

[0049] The report generation module is used to generate corresponding test reports based on the generated business data.

[0050] In one embodiment, the business function module further includes:

[0051] The display interface module is used to display the status data, monitoring data and test reports of the device virtual simulation module on the interface; specifically, the display interface module can obtain and display the internal status data of the device virtual simulation module in real time, such as the operating status of the device, parameter settings, simulation results, etc. These data are crucial for users to understand the current status and performance of the device. In addition to the status data of the device virtual simulation module, the display interface module can also display monitoring data. The display interface module can also load and display test reports generated by the report generation module. These reports may contain key information such as device test results, performance evaluation, fault analysis, etc. Users can easily obtain the contents of the test report through the report viewing function on the interface, so as to have a comprehensive understanding of software verification.

[0052] The log module is used to record the running status of the device virtual simulation module and related business information. The log module can capture and save various status information of the device virtual simulation module in real time during operation, including but not limited to the start, stop, abnormal interruption, parameter change, etc. of the module. In addition to the running status of the device virtual simulation module, the log module is also responsible for recording other important business-related information, such as user operation records, system configuration changes, business processing procedures, etc.

[0053] In one embodiment, the platform comprises at least:

[0054] PLC virtual simulation module that simulates the PLC equipment of the battery swap station; the PLC virtual simulation module can simulate the actual operating environment of the PLC equipment in the battery swap station. Through this module, the PLC program can be written, tested and debugged in a virtual environment without actually connecting to the physical PLC equipment. The functions of the simulated PLC equipment include: status monitoring, fault alarm, business logic processing, etc.

[0055] The charger simulation module simulates the charger of the battery swap station; the charger simulation module can simulate the actual charging process of the charger in the battery swap station. Through this module, various tests can be performed on the charger in a virtual environment to verify its performance and reliability, while reducing the risks and costs in actual testing.

[0056] In one embodiment, the communication between the PLC device and the station control system of the battery swap station usually adopts the CAN protocol, Modbus protocol and TCP protocol. Therefore, the PLC virtual simulation module can have a virtual device module corresponding to the CAN protocol communication, the Modbus protocol communication and the TCP protocol communication. That is, it has a communication interface for the CAN protocol communication, the Modbus protocol communication and the TCP protocol communication, and the functions of the simulated PLC device may include status monitoring, fault alarm, business logic processing, etc.

[0057] The communication between the charger and the station control system of the battery swap station usually adopts the CAN protocol, Modbus protocol and TCP protocol.
