System for measuring millisecond-level return response time of CAN bus product

[0024] The present invention will be further elaborated below in conjunction with embodiment.

[0025] The present invention provides a system for measuring millisecond-level return order response time of CAN bus products, which is an accurate measurement method and satisfies the requirement of applying CAN bus products to test and measuring the return order response time of the tested equipment less than or equal to millisecond level

[0026] Such as figure 1 As shown, the millisecond-level return order response time system mainly includes the product to be tested, a calculation conversion module, a test module, a first timing module, a second timing module, a return order analysis module and a response time calculation module;

[0027] The product to be tested: send its own status signal to the calculation conversion module in real time; its own status signal is a CAN command; the method for the calculation conversion module to judge its own status signal is to judge the flag b
