Abstract

The invention provides a network automation bus test bench which comprises a bus automation test bench and an external device, the bus automation test bench comprises a programmable power supply, an I / O control box, a fault control box, a basic control box and a gateway control box. The external device comprises a PC, all controllers and communication modules; the programmable power supply is connected with the I / O control box, the fault control box, the basic control box, the gateway control box and the PC. The communication modules are respectively connected with the I / O control box, the fault control box, the basic control box, the gateway control box and the PC, and all the controllers are respectively connected with the I / O control box, the fault control box, the basic control box, the gateway control box and the communication module. The invention further provides a network automation bus testing method, automatic control over power supply and fault injection is achieved, the result accuracy and testing efficiency of the testing rack are improved, and the testing cost of the rack is reduced.

Description

technical field [0001] The invention relates to the field of vehicle-mounted bus networks, in particular to a network automation bus test bench and a test method thereof. Background technique [0002] The vehicle bus network bench test is an indispensable link in the model development process. The network bench test mainly includes physical layer test, data link layer test, network management test, bus fault test, severity test, robustness test and so on. The composition of the bus network test bench generally includes power supply, controller, wiring harness and monitoring equipment. [0003] Operations such as power switching and fault injection in the test items such as network management test, bus fault test and robustness test in the existing bus network bench test are based on manual operations, and there are inconsistent operation methods, operation time cannot be obtained, and easy Misoperation and other problems occur, and it is difficult to locate and troubleshoo...
