Abstract: For the requirements of multi-system integration and linkage of coal mine safety monitoring system, by studying the fusion system, the business data, control instruction, the paper compared various data interaction technology, developed a data fusion and linkage communication protocol, established the database stored procedure based data interactive way, and a set of high efficient and reliable ground mixing and linkage interaction scheme is formed on the premise of safe and efficient optimization interaction process. The scheme has fewer interactive links, convenient connection and adjustment, high compatibility and high market application value.
