Abstract
The invention discloses a distributed automatic K line testing device and method based on CAN communication. The automatic testing device comprises a main console and multiple automatic detection modules. The main console is connected with the automatic detection modules through a CAN bus; each automatic detection module comprises a CAN bus communication module, a K line communication module and an indication module, and the automatic detection modules are connected with K line communication products to be detected through the K line communication modules. The main console transmits a message containing a testing command, each automatic detection module receives the message and transmits the testing command to the corresponding K line communication product to be detected, the K line communication modules receive test information fed back from the K line communication product to be detected and transmit the test information to the main console, and the main sole displays test results of all the K line communication product to be detected. By the adoption of the testing device and method, the testing efficiency is greatly improved, testing quality is ensured, equipment use ratio is increased, labor is saved, operation is convenient, and stability is high.
Description
Technical field
The present invention relates to automotive electronics, particularly relate to the distributed K line automatic testing equipment based on CAN communication and method of testing.
Background technology
In automotive electronics, K line is a kind of communication bus standard extensively adopted in the industry.K line is a kind of half-duplex serial communication.Because its agreement is simple, strong interference immunity and being applied by many car manufactures, K line communication product also obtaining and use widely in the car, in K line communication product production process, carries out function to K line communication product and stability test just seems very important.
Existing K line test is all the separate unit test undertaken by serial ports or USB port, and single device can only have the on-line testing of a K line communication product simultaneously, causes equipment and artificial significant wastage, inefficiency.Find more rationally, more efficiently, method of testing more easily, this is that the applicant endeavours one of content studied always.
Summary of the invention
The object of the invention is the deficiency existed for prior art, provide a kind of efficiency higher, accuracy is better based on the distributed K line automatic testing equipment of CAN communication.
For achieving the above object, the technical scheme that the distributed K line automatic testing equipment that the present invention is based on CAN communication adopts is:
A kind of distributed K line automatic testing equipment based on CAN communication, comprise supervisory control desk and multiple separate automatic detection module, supervisory control desk connects multiple separate automatic detection module by CAN, supervisory control desk is provided with display, automatic detection module comprises CAN communication module, K line communication module and indicating module, CAN communication module is connected with K line communication module, K line communication module is connected with indicating module, automatic detection module is by K line communication module and K line communication product connecting communication to be measured, separate between each automatic detection module, can not interfere with each other, automatic detection module is by realizing communication between CAN and supervisory control desk, supervisory control desk sends the message comprising test command by CAN, each automatic detection module can receive by CAN the message comprising test command, and send test command by K line communication module to K line communication product to be measured, the K line communication module of automatic detection module receives the detecting information from K line communication product feedback to be measured, by indicating module feedback test result, and by CAN communication module, detecting information is sent to supervisory control desk, supervisory control desk receives the test result of each automatic detection module feedback from CAN, show the test result of each K line communication product to be measured.
The present invention also provides a kind of method of testing of the above-mentioned distributed K line automatic testing equipment based on CAN communication:
Based on the method for testing of the distributed K line automatic testing equipment of CAN communication, after K line communication product to be measured powers on, supervisory control desk sends the message comprising test command by CAN, each automatic detection module can receive by CAN the message comprising test command, and send test command by K line communication module to K line communication product to be measured, the K line communication module of automatic detection module receives the detecting information from K line communication product feedback to be measured, by indicating module feedback test result, and by CAN communication module, detecting information is sent to supervisory control desk, supervisory control desk receives the test result of each automatic detection module feedback from CAN, show the test result of each K line communication product to be measured, if any fault part, show the fault message of this fault part.
The present invention compared with prior art, has the following advantages:
The present invention is directed to the deficiencies in the prior art, disclose one more efficiently, more rationally, automatic testing equipment and method of testing more accurately, in test process, do not need personnel's Attended Operation, substantially stop misoperation and erroneous judgement.Under the invention reside in the condition significantly not increasing hardware cost and human cost, utilize automatic detection module to carry out grouping test, a K line communication product for our company carries out test and comparison, and the testing time shortens greatly, save time 75% than separate unit test, utilization rate of equipment and installations significantly improves.Particular/special requirement is not had to tester, just can on dutyly test for one time as long as normal operations work instructs.The input and output of signal are all realized automatically by testing apparatus, there will not be misjudgment phenomenon, and accuracy rate reaches 100% substantially.Adopt testing apparatus of the present invention and method of testing testing efficiency to be greatly improved, test mass is guaranteed, and utilization rate of equipment and installations is greatly improved, and saves artificial, easy to operate in test process, good stability.
