Detailed description of the invention
Fig. 1 is the system structure diagram of the utility model.
Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical
It is novel, it is not intended to limit the scope of the utility model.
As shown in Figure 1, the utility model embodiment provides a kind of automated detection system of intelligent instruments in vehicles:
The onboard instruments include at least the first MCU and the first CAN chip, the first MCU and the first CAN
Chip is connected by CAN bus；
The system includes video capture device, video process apparatus, the 2nd MCU, the 2nd CAN chip, usb interface module
And LED light；
The video capture device is sent to video process apparatus by serial communication interface；The video process apparatus is logical
UART interface is crossed to connect with the I/O interface of the 2nd MCU；The 2nd CAN chip respectively with the first CAN chip and the 2nd MCU
I/O interface electrical connection；The usb interface module for connecting the video process apparatus and the USB storage of peripheral hardware is set
It is standby；The I/O interface of the LED light and the 2nd MCU.
2nd MCU of automated detection system be responsible for send test instruction to test vehicle intelligence instrument the first MCU, into
Enter test pattern, carries out the automatic detection of related series function, while the 2nd MCU will test as the result is shown in LED light
On.If test passes through, green light is shown, test does not pass through, then shows red light.Test process is sent to by UART interface simultaneously
Inside the external USB storage device of video process apparatus, convenient for retrospect and tested intelligence instrument poor prognostic cause is analyzed.
2nd CAN chip is responsible for the signal of the 2nd MCU is internally converted into CAN signal being sent to the first CAN chip, or will
The CAN signal that first CAN chip is sent is converted into rs 232 serial interface signal and issues the 2nd MCU, leads to the first MCU and the 2nd MCU
News.
Video capture device is a high-definition camera, acquires the variation of the display picture on intelligence instrument.It is sent to video
Processing unit.
Video process apparatus is a graphics image processor for being stored with image processing program, passes through serial line interface and video
Equipment connection is acquired, the vision signal sended on high-definition camera is received, using existing image processing techniques, to video
Content analyze and communicated by UART interface and the 2nd MCU, receives the corresponding test that the 2nd MCU is sended over and refers to
It enables, whether intelligence instrument performs correct operation after contrast test instruction is sent to intelligence instrument, stores the result into USB and sets
In standby.
Test vehicle intelligence instrument includes but there was only the first MCU, the first CAN chip.Power on automatic test after triggering
Mainboard is to test vehicle intelligence instrument.First MCU is communicated by the first CAN chip and the 2nd MCU, receives the 2nd MCU hair
Instruction out executes corresponding function, is shown on intelligence instrument.Trigger signal is the command signal of a succession of complexity, is prevented
This command signal is triggered after practical entrucking.
2nd MCU is STM32F103, and being tested the 2nd MCU inside complete machine can be various instrument MCU,
The STM32F103 that can also be used.The first CAN chip and the 2nd CAN chip are TJA1040.The UART is
Universal asynchronous receiver-transmitter universal asynchronous receiver-transmitter, the CAN are
Controller Area Network controller LAN.
The utility model has the characteristics that simple design, high degree of automation, testing efficiency are high, can be widely applied to automobile
Field of electronic systems.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
