The equipment with the same function can be used by multiple manufacturers in many times, so that the problem is brought that the communication protocols or control modes of the equipment of different manufacturers are different, so that the equipment control program written for each manufacturer cannot be used universally, and the equipment control mode (such as eye pattern extinction ratio reading, template allowance reading, optical power metering reading, optical attenuation value setting and the like) of each function needs to be abstracted into an interface, and an upper module is used for calling; finally, creating concrete device subclasses, inheriting the concrete device subclasses from the corresponding middle-layer abstract subclasses, and realizing interfaces provided in the parent class; when the equipment with a certain function is replaced or introduced into other manufacturers, the written and tested codes are not required to be modified, and only a specific subclass is required to be added and the corresponding interface is required to be realized. Further, in order to make the device configuration more universal, the device can be flexibly added or deleted in the configuration interface according to different requirements of the automatic test system, and the communication test can be performed on the device, the device parameters of each function are different, so that the configuration interface is also different, an abstract device configuration parent class is created, the universal functions of the device configuration (such as creation, loading and the like of device configuration objects) are realized, then device configuration subclasses of all specific functions are created, inherited from the device configuration parent class, the respective unique setting parameters are added in each subclass, and the configuration interface is rewritten, so that the dynamic addition, deletion and modification of each device configuration interface can be conveniently realized, and the device configuration in the automatic test system can be more universal and flexible due to the design.

In a man-machine interaction operation interface, a right mouse button is clicked at the blank position of a device list box, a certain device is selected to be added or the selected added device is selected to be deleted in a pop-up menu, so that the addition and deletion of the device can be realized very simply through mouse operation, and thus, for different optical module automatic test systems, the configuration program of the device can be flexibly configured according to requirements, the device configuration program is completely separated from specific test requirements, the device configuration program is not influenced by each other, different test requirements can be adapted without modifying any codes, and better universality can be realized.
