Embodiment Construction
[0030] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0031] The present invention is equipped with a tooth head information reading device on the test device. When testing the plug-in, the plug-in is inserted into the test device, and the tooth head information reading device reads the identification feature information of the plug-in to prevent wrong insertion of the tooth head and sends it to the PC. computer and PC set the test environment according to the identification feature information, and drive the test device to test the plug-in. Since the identification feature information uniquely corresponds to the plug-in, the automatic setting of the test environment based on the identification feature information can effectively improve the accuracy and efficiency of plug-in identifi...

The invention relates to a plug-in unit identification system of a common testing interface, which comprises a plug-in unit, a testing device, a testing cable, a controller, a toothed head information reading device and a controller. The plug-in unit is provided with a false plugging prevention toothed head, and the false plugging prevention toothed head is provided with label feature information; the controller is connected with the testing device through the testing cable, and the testing device is provided with the toothed head information reading device matched with the false plugging prevention toothed head; the false plugging prevention toothed head is used for reading the label feature information when the plug-in unit is plugged in the testing device and transmitting the information to the controller; and the controller is used for constructing a testing environment according to the label feature information and testing the plug-in unit. The invention also provides a plug-in unit identification method for the common testing interface. The testing environment can be set automatically according to the label feature information of the false plugging prevention toothed head of the plug-in unit, and the accuracy and efficiency of plug-in unit identification can be effectively improved.
Description
technical field [0001] The invention relates to the field of software testing, in particular to a plug-in identification system and method for a general testing interface. Background technique [0002] The electronic control cabinet is the control core of the electric locomotive. It consists of a traction control system, a braking control system, and an anti-idling (anti-skidding) control system. The above-mentioned systems realize the traction control, braking control, and anti-idling control of the locomotive. The plug-in box of the electronic control cabinet has various functions such as input / output plug-in, protection logic plug-in, pulse forming plug-in, pulse amplification plug-in, characteristic control plug-in, frequency conversion plug-in, anti-idling plug-in, conversion control plug-in, and voltage given plug-in Plug-ins, using these plug-ins, the electronic control cabinet updates the control functions. [0003] In order to facilitate the assembly of plug-ins wi...
