[0002] As an important part of existing engineering equipment, the electronic control system of engineering equipment plays a key role in improving mechanical efficiency, ensuring operation safety, and optimizing management with its excellent performance and significant advantages.

[0003] If a failure occurs in the electronic control system during the use of the engineering device, it may lead to serious safety accidents. Therefore, during the production and manufacturing process of engineering equipment, according to the equipment development and guarantee requirements, a large number of experimental verifications need to be carried out on the electronic control system of engineering equipment to ensure the correctness, stability, and safety of the performance of the electronic control system, so as to ensure that the engineering equipment can operate stably and safely after leaving the factory.

[0004] Currently, in actual production, first, the staff needs to conduct preliminary performance analysis and design verification on the electronic control system, then install and verify the analyzed and designed electronic control system, and then the test personnel need to manually build and configure the test environment to test each part of the electronic control system of the engineering equipment one by one. In this way, not only is the test speed slow, but also a large amount of human, time, and material costs are required, and due to the unstable operation state of the electronic control system, safety accidents are prone to occur.

[0005] Therefore, the existing electronic control system test devices have the disadvantages of poor integration, slow test response speed, inconvenient operation, and the need for multiple people to cooperate in the test. To solve these problems, there is an urgent need for an electronic control system test bench that is convenient to operate and has intuitive and clear test results to meet the needs of actual production and the development of engineering equipment.

The change of corresponding values is observed through the computer. If the value change is abnormal, the corresponding functions of the electronic control system are not realized or there are faults.

[0013] Further, the integrated controller has a CAN interface, and the CAN interface is connected to a computer through USB. In the automatic mode, corresponding bus commands are sent through the computer to test the corresponding functions of the operation controller of the electric control system under test and the closed-loop pump control box, and after being processed by the integrated controller, they are output to the computer in the form of CAN signals for testers to intuitively observe the test results.

[0014] Further, the test box is connected to the integrated controller, the operation control box, and the closed-loop pump control box through a test cable. One end of the test cable is provided with an aviation plug, and the aviation plug is inserted into the aviation socket on the test box for connection.
