3. System parameters
. Each experimental bench is equipped with universal casters for easy movement. Length*width*height=** (excluding the height of installation components)
. The experimental bench can be used independently or through a bus network
. Each has an inch display screen to display the input and output of the electronic control system in real time. Status and text description to enhance teaching effect
. Use metal shell for protection and installation. Replaceable length*width=*
. Provide schematics, source codes, door files, and demonstration projects, which can be used for student course design and graduation projects. , professional technology development and other uses also support user secondary development
. The external terminals have reserved test holes to facilitate experimental detection and circuit analysis
. The core control board is replaceable. When replaced as a student, it can meet the teaching needs of design (program modification, board design, schematic design, etc.), assembly, installation, debugging, etc.
The bus network structure refers to the Volkswagen Passat model and provides similar control to the original car. Strategy
.Each experimental platform has local control function, network control function and virtual simulation comprehensive experiment function
. Control unit
. The platform software is an integration for the development, testing and analysis related to vehicle network The development environment software covers the complete development process from vehicle network system planning to implementation, which can improve the efficiency of developing network-based and vehicle networks. The software platform mainly includes three functional modules: database function module, measurement function module, Simulation function module. Supports protocol development, measurement, simulation, analysis, data recording, data playback, etc. of vehicle network systems.
. Measurement: Real-time reflection of the bus status and related information of the vehicle network in the form of data, graphics, charts, etc.
. Simulation: Used for vehicle network simulation including software simulation and hardware-in-the-loop simulation.
. Diagnosis: Complete a single communication function test and a comprehensive test of multiple connected networks.
.Testing: Test the bus communication function at each stage of the development process.
. Data recording and playback: Bus data can be recorded and the recorded data can be played back.
. Can display bus load, real-time flow, maximum load, and maximum flow in real time.
. Can send user-defined protocol frames for simulation operations, with keyboard input, time and other trigger functions.
. Support users' communication protocol analysis of communication information such as engine speed, vehicle speed, water temperature, car light status, door closing status, etc. of most vehicle models.
