Abstract: This paper analyzes the problem of disunity of communication interface and protocol of underground electromechanical equipment found in the process of intelligent construction of coal mine by Shendong Coal Branch of National Energy Group, and puts forward the requirement of developing the compliance inspection system of electromechanical equipment EIP communication protocol standard according to the EIP Communication Protocol Standard of Electromechanical Equipment of Shendong Coal Branch. The content of protocol standard is analyzed in detail, the key technologies of structured storage and programmed expression of protocol module are studied, and the design and implementation of “Shendong Coal Branch Electromechanical Equipment EIP Protocol Data Consistency Detection System” is completed through the key processes of demand analysis, architecture design, function design and system trial run.
