Controller development and test platform

Abstract

The invention discloses a controller development and test platform comprising a development computer and a signal simulation test circuit board. The development computer is equipped with simulation test software, and is used for outputting a control instruction for simulating the actual working signal environment of a controller to the signal simulation test circuit board through the simulation test software. The signal simulation test circuit board is used for simulating the actual working signal environment of a controller during working according to the received control instruction and outputting the simulation result to the controller. A developer monitors the development parameters of the controller product, and adjusts the development of the controller. The controller development andtest platform has the advantages as follows: (1) development and test are made simpler and more convenient; (2) the timeliness of test is improved; (3) test related devices are more mobile, and can be used directly in offices; (4) the working environment and parameters of an actual controller product can be accurately simulated; (5) the work efficiency of development and test is improved, and thedevelopment cycle is shortened; and (6) the test cost is saved.

Description

technical field [0001] The invention relates to the field of controller testing, in particular to a controller development and testing platform. Background technique [0002] The controller is the core component of the diesel engine SCR (Selective Catalyst Reduction, Selective Catalyst Reduction) selective catalytic conversion system that controls the entire system to work. The function of the controller directly affects the operation of the entire SCR system and affects the control of emission results. The function of the SCR controller depends on its design, development and testing. Therefore, the development and testing of controller functions directly affects the entire SCR system, which affects emissions. At present, the development and testing of controllers do not involve any testing tools. Developers develop codes according to the text requirements, and then test after the development is completed. There are many shortcomings in the development and testing of exist...

Therefore, the development and testing of controller functions directly affects the entire SCR system, affecting emissions

At present, the development and testing of controllers do not involve any testing tools. Developers develop codes according to the text requirements, and then test after the development is completed. There are many shortcomings in the development and testing of existing methods: 1. Development work It is out of the actual demand and cannot be tested in time; 2. After the test, if you encounter problems, you need to adjust and test repeatedly; 3. The test equipment is not convenient enough, and developers need to move to work; 4. The test equipment cannot completely and accurately simulate the actual product Fifth, the test equipment is not simple and easy to use; Six, the existing development and testing consume a lot of time and energy of the development and testing personnel, which is not conducive to the industrialization of the SCR system
