Description

Technical Field

[0001] This invention relates to the field of chemical composition and capacity testing technology, and in particular to a method and system for simulating and debugging chemical composition and capacity testing equipment. Background Technology

[0002] As electric vehicles gradually replace gasoline vehicles, the installed capacity of power batteries has also increased significantly. Power batteries are composed of several cells connected in series and parallel. After the cells are produced, they need to be processed by a formation and capacity testing device. Formation is the initial charge and discharge of the cells to activate the chemical substances inside the cells. Capacity testing is the sorting of the cells by capacity and quality. Formation and capacity testing directly affect the quality of power batteries, so it is necessary to test the formation and capacity testing device before leaving the factory.

[0003] The commissioning of formulation and capacity testing equipment relies on testing equipment. Traditionally, the method of connecting the equipment to the testing equipment for each test item has the following drawbacks: 1. There are many types of formulation and capacity testing equipment, including automatic / manual, series / parallel, and simplified / bypass types. Each type requires a separate testing equipment, leading to high commissioning costs. 2. All conditions must be met simultaneously for each test item to begin commissioning, resulting in low efficiency. Meeting these conditions also wastes energy, further increasing costs. For example, insufficient air pressure necessitates starting the air compressor, which is only a prerequisite in the commissioning process. Energy is wasted until other conditions are met. 3. Commissioning requires the cooperation of personnel from multiple departments, with each department's staff arriving on-site to resolve issues, wasting significant human and material resources.

[0004] Therefore, how to provide a simulation debugging method and system for formation and capacity testing equipment to improve debugging efficiency and reduce debugging costs has become an urgent technical problem to be solved. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a method and system for simulating and debugging a formation and capacity testing device, so as to improve the debugging efficiency of the formation and capacity testing device and reduce the debugging cost.

[0006] In a first aspect, the present invention provides a method for simulating and debugging a formation and capacity testing device, comprising the following steps:

[0007] Step S10: The PLC sets up several simulated workstations and one global workstation;

[0008] Step S20: Based on the hardware differences of various types of batching and capacity-deploying equipment, the PLC sets the general debugging steps and special debugging steps for the simulated station and the global station.

[0009] Step S30: The PLC connects to the formation and capacity testing equipment via the experimental platform, and performs simulation debugging on the formation and capacity testing equipment based on the simulated workstation and the global workstation.

[0010] Furthermore, in step S10, the simulated workstation and the global workstation are set based on the serial port simulation debugging program, Modbus RTU debugging program, Modbus TCP debugging program, Kepware, UDP debugging program, and GETPUT debugging program.

[0012] Furthermore, in step S10, the global workstation is used to simulate the global IO conversion, global abnormal alarm, global probe debugging origin summary, initialization, startup, and equipment management of the capacity-deployment device.

[0013] Furthermore, step S30 also includes: generating and displaying a simulation debugging report.

[0014] Secondly, the present invention provides a simulation and debugging system for a formation and capacity testing device, comprising the following modules:

[0015] The workstation setting module is used to set up several simulated workstations and one global workstation in the PLC;

[0016] The debugging step setting module is used by the PLC to set the general debugging steps and special debugging steps of the simulated station and the global station based on the hardware differences of various types of modularized capacity-deploying equipment.

[0017] The simulation debugging module is used by the PLC to connect to the formation and capacity testing equipment via an experimental platform, and to perform simulation debugging of the formation and capacity testing equipment based on the simulated workstation and the global workstation.

[0027] The overall concept of the technical solution in this application embodiment is as follows: A simulation debugging platform is set up in the PLC, and the system is broken down into parts, unit tests, and simulated shielded integration tests are performed. According to the type of test for the broken-down capacity device, it is divided into server component testing and client component testing. Debugging is carried out in conjunction with tools such as Modbusslave, serial port debugging assistant, network port debugging assistant, and Kepware. In order to achieve different debugging conditions, multi-functional shielded tests and simulated input programs are required. According to the communication structure, it is classified into serial communication debugging, Modbus RTU debugging, Modbus TCP / IP debugging, external signal IO communication debugging, CAN communication debugging, etc. Each type of debugging is made into a corresponding general debugging step or a special debugging step.

[0028] Please refer to Figures 1 to 2 As shown, a preferred embodiment of the present invention, a method for simulating and debugging a formation and capacity testing device, includes the following steps:

[0029] Step S10: The PLC sets up several simulated workstations and one global workstation;

[0034] In step S10, the global workstation is used to simulate the global IO conversion, global abnormal alarm, global probe debugging origin summary, initialization, startup and equipment management of the capacity-deployment equipment.

[0035] Step S30 further includes: generating and displaying a simulation debugging report.

[0036] A preferred embodiment of the present invention provides a simulation debugging system for a chemical composition and capacity testing device, comprising the following modules:

[0037] The workstation setting module is used to set up several simulated workstations and one global workstation in the PLC;

[0038] The debugging step setting module is used by the PLC to set the general debugging steps and special debugging steps of the simulated station and the global station based on the hardware differences of various types of modularized capacity-deploying equipment.

[0039] The simulation debugging module is used by the PLC to connect to the formation and capacity testing equipment via an experimental platform, and to perform simulation debugging of the formation and capacity testing equipment based on the simulated workstation and the global workstation.

[0040] In the workstation setting module, the simulated workstation and the global workstation are set based on the serial port simulation debugging program, Modbus RTU debugging program, Modbus TCP debugging program, Kepware, UDP debugging program, and GETPUT debugging program.

[0041] In the workstation setting module, the simulated workstation is used to simulate the IO conversion, abnormal alarm, abnormal stop, probe debugging origin summary, probe local single action, automatic testing, test result output and data processing of the capacity-setting equipment.

[0042] In the workstation setting module, the global workstation is used to simulate the global IO conversion, global abnormal alarm, global probe debugging origin summary, initialization, startup and equipment management of the capacity-deploying equipment.

[0043] The simulation debugging module also includes generating and displaying simulation debugging reports.

[0044] To facilitate understanding of the present invention, the following further explanation is provided:

[0045] First, a network platform without mechanical components is built based on the PLC. To ensure that the I / O signal addresses of different experimental machines are the same, the hardware, software, and modules are structured. Hardware structuring involves analyzing the similarities and differences of all modularized capacity-matching devices, prioritizing the hardware with similar components first and planning the different components later to ensure relatively unified program physical addresses and reduce maintenance problems later. Software structuring involves classifying the PLC program according to mechanical workstations. Each workstation contains a unified subroutine framework. For debugging, a debugging program block is added, which consists of various combinations of simulation debugging programs to facilitate the mapping of I / O points of different experimental machines. An output block program controls different outputs, and the output signals are connected to the workstation input points to simulate different input signals of different machines. This allows for multiple combinations on one platform to debug different experimental machines, improving efficiency and saving costs. An important submodule under the debugging module is responsible for other host computers, intermediate computers, acquisition boxes, and serial port program templates. Each part is independent, facilitating communication and debugging of different parameters.

[0046] Hardware structured classification: Formation and capacity separation have 2 or 3 storage locations. The difference between formation and capacity separation is that formation has an additional input module to determine the liquid level status.

[0047] Software structured classification: Ensures program consistency across different devices. Simulated workstations are categorized into test items based on their capacity requirements. Each item has a separate test program. Multiple experimental machine combination input switching programs address the different inputs of different types of equipment. Different structures are customized for each experimental machine. The equipment simulates switching switches to turn on or off, and the simulated output is mapped according to the experimental machine. Then, output signals are given through the sequence of work steps to ensure that the PLC input points have signals for actual actions, thus testing the operation of different experimental machines.

[0048] This is a serial port template debugging program / ModbusRTU template debugging program. The program is written according to the communication format, downloaded to the PLC via the network port, and monitored. A Modbus slave acts as the server. Through serial port and network port settings, the Modbus slave can change register values ​​or force output to PLCO points and PLC internal contacts. Results can be observed through PLC network port monitoring. This allows debugging even when the external serial port device is not present, ensuring the correctness of this part of the template program.

[0049] ModbusTCP host computer template debugging program / ModbusTCP mid-computer template debugging program / UDP communication test. It uses Kepware to add PLC and uses Modbusslave to simulate communication in various ways. It writes the host computer and mid-computer parameters into the PLC, and can simulate the output value in the absence of a mid-computer or host computer.

[0050] The Siemens GETPUT test targets Siemens 200Smart. It uses Kepware to add the PLC model, uses Modbus slave as the server, and sets up serial ports to achieve data exchange between the PLC and Modbus slave.

[0051] In summary, the advantages of this invention are:

[0052] By setting up several simulation stations and one global station on the PLC, and based on the hardware differences of various types of formation and capacity testing equipment, general and special debugging steps are set for the simulation stations and the global station. Then, the formation and capacity testing equipment is simulated and debugged based on the simulation stations and the global station. The PLC can connect to various types of formation and capacity testing equipment through a single experimental machine for simulation and debugging. It is not necessary to meet all conditions at the same time before debugging begins, and it is not necessary to mobilize personnel from multiple departments to cooperate. This greatly improves the debugging efficiency of formation and capacity testing equipment and greatly reduces the debugging cost of formation and capacity testing equipment.
