The embodiment of the invention provides a testing system, a testing method and testing equipment. The testing system comprises a real-time processing system, an upper computer, an IO interface module and a load configuration module, wherein the upper computer, the IO interface module and the load configuration module are connected with the real-time processing system. The upper computer is configured to be used for controlling and monitoring the real-time processing system and judging whether the working state of the controller to be tested is normal or not according to a preset judgment standard; the IO interface module comprises a plurality of IO ports and is used for connecting a controller to be tested; the load configuration module is configured to simulate actual operation of a load according to a driving signal sent by the controller to be tested; the real-time processing system is configured to configure the IO interface module and the load configuration module according to a control instruction sent by the upper computer so as to enable the controller to be tested to present different operation states, receive a controller signal sent by the to-be-tested controller, send the controller signal to the upper computer, detect and analyze the working condition in the process that the controller to be tested drives the load configuration module to operate, and send a detection report to the upper computer.
Description
technical field [0001] The present invention relates to the technical field of controllers, in particular to a testing system, testing method and testing equipment. Background technique [0002] With the continuous development of science and technology and the continuous improvement of production demand, it has become a trend that the production capacity and testing ability are developing towards a more efficient, fast and reliable direction. The traditional test relying on manpower or using multiple instruments is not suitable for it. current usage requirements. [0003] In order to ensure that the performance of the controller meets the factory or use requirements, it is necessary to conduct a unified test on the controller. Its test content includes various signals of the controller, such as: analog input, analog output, digital input, digital output, frequency input, frequency output, drive output and speed output signals related to the automotive field. , in addition ...
