Description

Distributed K line automatic testing equipment based on CAN communication

Technical field

This utility model relates to automotive electronics, particularly relates to the distributed K line automatic testing equipment based on CAN communication.

Background technology

In automotive electronics, K line is a kind of communication bus standard widely used in the industry. K line is a kind of half-duplex serial communication. Because its agreement is simple, strong interference immunity and applied by many car manufactures, K line communication product also being widely used in a variety of applications in the car, in K line communication product production process, K line communication product is carried out function and stability test just seems critically important.

The test of existing K line is all the separate unit test undertaken by serial ports or USB port, and single device can only have a K line communication product on-line testing simultaneously, causes equipment and artificial significant wastage, inefficiency. Finding more reasonable, more efficient, method of testing more easily, this is always up one of the applicant's content endeavouring research.

Utility model content

The purpose of this utility model is the deficiency existed for prior art, it is provided that a kind of in hgher efficiency, accuracy is better based on the distributed K line automatic testing equipment of CAN communication.

For achieving the above object, this utility model the technical scheme is that based on the distributed K line automatic testing equipment of CAN communication

A kind of distributed K line automatic testing equipment based on CAN communication, including 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 includes 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, between each automatic detection module separate, will 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 receives the message comprising test command such as through CAN, 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 test information from K line communication product to be measured feedback, by indicating module feedback test result, and by CAN communication module, test 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.

This utility model also provides for the method for testing of a kind of above-mentioned distributed K line automatic testing equipment based on CAN communication:

Method of testing based on 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 receives the message comprising test command such as through CAN, 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 test information from K line communication product to be measured feedback, by indicating module feedback test result, and by CAN communication module, test 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.

This utility model compared with prior art, has the advantage that

This utility model for the deficiencies in the prior art, disclose a kind of more efficient, more rationally, automatic testing equipment and method of testing more accurately, in test process need not personnel's Attended Operation, substantially stop maloperation and erroneous judgement. When this utility model is in that not dramatically increase hardware cost and human cost, utilizing automatic detection module to carry out packet test, a K line communication product for our company carries out test and comparison, and the testing time is greatly shortened, testing the saving time 75% than separate unit, utilization rate of equipment and installations is greatly improved. Tester is not had particular/special requirement, just can on duty test for one time as long as normal operations work instructs. The input of signal and output are all automatically obtained by test device, do not have misjudgment phenomenon, and accuracy rate basically reaches 100%. Adopting test device of the present utility model and method of testing testing efficiency to be greatly improved, test quality is guaranteed, and utilization rate of equipment and installations is greatly improved, and saves artificial, easy to operate in test process, good stability.
