Extensible communication framework supporting multiple communication protocols and communication method

Abstract

The invention provides an extensible communication framework supporting multiple communication protocols, for connecting a software platform and equipment. The extensible communication framework comprises a communication interface and a communication model, wherein the communication interface comprises an equipment interface, a channel interface and a protocol interface, and the communication model calls the equipment interface, the channel interface and the protocol interface during communication; when the software platform is connected with equipment, a class is newly built in the equipmentinterface, and the class is inherited from the equipment interface; a channel protocol is newly established in the channel interface, wherein the channel protocol is inherited from the channel interface; a sub-protocol interface is newly established in the protocol interface, wherein the sub-protocol interface is inherited from the protocol interface; and the software platform communicates with the equipment through the communication model, and class, channel protocol and sub-protocol interfaces are called in the communication process. According to the extensible communication framework supporting multiple communication protocols, software code maintenance and function addition become very convenient, and finally, the product software quality is guaranteed.

Description

technical field [0001] The invention designs the field of semiconductor testing, and in particular relates to an extensible communication framework and a communication method supporting multiple communication protocols. Background technique [0002] In the prior art, different communication protocols are developed using corresponding communication libraries, so as to establish communication with devices. Such as socket (TCP / UDP), GPIB, COM, etc., each type of protocol has its own interface function definition (including names and parameters) in different development languages ​​(C / C++ / JAVA / C#, etc.). [0003] Due to differences in protocols and development languages, the interface definitions of related communication libraries are varied and different (mainly reflected in function names and parameters). Disconnect, some are called Close, some are called Disconnect. [0004] The difference in the interface of the communication library will lead to the code of the business l...

AI Technical Summary

Problems solved by technology

[0005] In the prior art, when the software platform communicates with the device, the main problem is that the communication protocol is different due to the difference of the device, which leads to the inability to realize the unified and standardized communication process, including the inconsistency of the communication interface and the inconsistency of the communication model.
