Abstract
A BCM product automatic test system of a CAN bus is provided. The system is composed of an industrial control computer, a digital IO expansion card, a simulation input and output expansion card, a CAN communication expansion card and a virtual load box. A method of using the industrial control computer to expand an industrial expansion card is adopted to simulate BCM input port control and output port detection, a CAN interface card is adopted to realize CAN bus communication, send diagnosis control instructions and receive BCM state information, and a virtual load is adopted to simulate a BCM output port load, thus BCM automatic tests can be realized. In the BCM product automatic test system, function tests of different BCM products can be satisfied through adjusting configuration of the system, and automatic test projects have wide coverage, and is rapid in speed and low in labor intensity. Production line bottleneck problems can be solved, productivity can be greatly enhanced, and the test is suitable for large-scale popularization.
Description
Technical field
The utility model relates to car body controller testing apparatus field, particularly relates to a kind of BCM product Auto-Test System of CAN bus.
Background technology
The application of BCM (car body control module) very extensively, the IO port with the BCM product of CAN bus is many in the market, steering logic is complicated, many states need CAN to communicate by letter and the support of JS1939 agreement.In process of production, test job trivial operations, workload are big, have a strong impact on work efficiency, cause and produce the line bottleneck, cause production capacity to improve.
Summary of the invention
The utility model is to the problems that exist in the present prior art, provide a kind of simple to operate, workload is little and the BCM product Auto-Test System of work efficiency effectively is provided.
For achieving the above object, the utility model adopts following technical scheme:
The BCM product Auto-Test System of CAN bus is made up of industrial computer, Digital I expansion card, analog input output expansion card, CAN communication expansion card, dummy load case, BCM to be measured; Digital I expansion card, analog input output expansion card, CAN communication expansion card are installed on the industrial computer; The signal output part of Digital I expansion card, analog input output expansion card is connected to BCM input end to be measured; BCM signal output part to be measured is connected to the dummy load case; Dummy load case output end signal feedback is connected on Digital I expansion card, the analog input output expansion card, and CAN communication expansion card is connected on the BCM to be measured.Input port control and output port that the mode that we adopt industrial computer to expand industrial expansion card is simulated BCM detect; Carry out the CAN bus communication through the CAN interface card; Send the diagnosis control instruction, receive the status message of BCM, and utilize dummy load simulate BCM the output port load.Thereby realized the automatic test of BCM.
This BCM product Auto-Test System can satisfy the functional test of the BCM product of different series through the configuration of Adjustment System, and the automatic test project covers entirely, speed is fast, labour intensity is low.Solve product line bottleneck problem, can significantly improve production capacity, be fit to large-scale promotion.
