The invention provides a method, a device and a system for testing a function of an air conditioning controller. The method comprises the following steps that: a test device sends a test command to a test board; the test board simulates air conditioning running working condition data to obtain simulation data; the test board sends the simulation data to a tested controller; the test board detects the tested controller and sends detection data to the test device; and the test device judges whether the function of the tested controller is normal according to the detection data. By the invention, the function of the air conditioning controller can be detected automatically, so that the detection speed can be increased.

Method, device and system for testing function of air conditioning controller

The invention discloses an automatic test system based on character recognition. The automatic test system based on character recognition comprises a testing terminal and an image collecting device. The image collecting device is used for collecting the actually output image of a display device to be tested, and transmitting the actually output image to the testing terminal. The testing terminal is further used for intercepting a specified area image of the actually output image, recognizing an actual character string of output information of the specified area image and judging whether the character string is the same as a corresponding standard character string. If the actual character string is the same as the corresponding standard character string, the information that a test is normal is produced; if the actual character string is not the same as the corresponding standard character string, the information that the test is abnormal is produced. The automatic test system based on character recognition is automatic, fast and simple. Reliability of testing efficiency and the test result of the display device is improved, and research and development time and cost of the display device can be further reduced effectively.
