Embodiment 1

[0017] figure 1 Shown is the block diagram of the comprehensive training platform for automotive electronics based on graphical programming, including graphical programming platform, emulator, hardware platform and hardware equipment. The graphical programming platform includes ECU motherboard driver, several sensor program modules, several actuator program modules and basic program structure modules encapsulated in graphic elements. The hardware platform includes an MCU, several sensor interface circuits and several actuator drive circuits. The hardware equipment includes an equipment rack, several sensor modules, several actuator modules and connecting wires of standard interfaces.

[0019] figure 2 Shown is a block diagram of the graphical programming platform of the patent of the present invention, including an ECU motherboard driver package unit, several sensor program module package units, several actuator program module package units, and several basic program structures packaged in graphics units module.

Embodiment 3

[0021] image 3 Shown is the block diagram of the operation mode of the patent of the present invention. Students use the mouse to click and drag the packaged graphic elements, and place them in the virtual world for programming. At the same time, each module in the hardware platform is connected with wires in the same connection scheme. Compilation and debugging can be divided into two methods. The first method is to use the graphical programming platform to first generate the C language source program, then use the programming environment applicable to the MCU to compile and connect, and finally generate the machine language and download it to the hardware platform for testing. If If the function is abnormal, return to the programming environment to modify the C language source program until the test is successful.

[0022] The second method is to use the graphical programming platform to directly generate machine language, then download it to the hardware platform, and tes...

Abstract

The invention relates to an automotive electronic control system integrated training platform based on graphical programming. The automotive electronic control system integrated training platform comprises two parts including a hardware platform and a software system. The hardware portion comprises an ECU mainboard, a programming simulator, several sensor modules and several actuator modules. Thesoftware portion comprises a graphical programming platform which is configured with driving programs of the ECU mainboard, the sensors and actuator hardware circuits. The automotive electronic control system integrated training platform is characterized in that graphical programming can be carried out on the ECU; a C language program is generated by means of software for debugging; software and hardware modules can be combined flexibly to simulate automotive electronic control systems in different types; basic functions of a set of electronic control system can be simulated and shown; the signal processing process of an automotive sensor can be visually understood; and fault simulation training can be carried out on the automotive electronic control system. According to the invention, byemploying the graphical programming tool, the programming difficulty when students carry out simulation and development training on automotive electronic products is reduced, and the processing process of signals on the ECU can be visually displayed.

Description

technical field [0001] The patent of the present invention relates to a teaching and training platform for automotive electronic control systems, especially a set of teaching and training equipment, which can be widely used in teaching and training of automotive electronics and related courses. Background technique [0002] The existing automotive electronic teaching and training platform usually adopts the method of hardware simulation, that is, according to the training content, the students use the wires with a unified plug to connect the required modules on the experimental bench, simulate the real vehicle starting system, observe the experimental phenomena, measure Voltage and current signals. There are defects in this method of using hardware simulation. Since students cannot access the control program inside the MCU, the teaching and training still remain at the level of splicing simulation, measurement and observation, and they can only have a simple perceptual under...
