Abstract: Networking architecture of large -scale electromechanical equipment in coal mine based on FTP has problems such as complex data exchange protocol, high pressure of database reading and writing, easy damage of server disk and failure of reading text file after network blocking. According to data characteristics of large -scale electromechanical equipment in coal mine, a networking architecture of large -scale electromechanical equipment in coal mine based on Redis was proposed. The collected data of large -scale electromechanical equipment in coal mine is transmitted from Redis client to Redis server in Redis publish/subscribe mode, which reduces data flow link and improves efficiency of data transmission. The Redis server pushes the received data to data parsing program, which completes data reverse parsing, and the parsed real -time data is cached into Redis memory database, so as to improve real -time data access speed and reduce reading and writing pressure of relational database. Data transmission interrupt caching mechanism is used to realize data continuous transmission after interruption and avoid data loss. Distributed deployment of the Redis server and data parsing program is realized by using Redis cluster function, which improves efficiency of data parsing. The practical application results show that the proposed architecture has characteristics of low real -time data delay and fast real -time data query speed, which can meet needs of superior supervision department of coal mine for online, rapid and effective control of large -scale electromechanical equipment in coal mine.
