Abstract: For problem that transmission data in TD-SCDMA communication system of coal mine easily loss or change influenced by environmental factor, the paper proposed a scheme of using message middleware technology in coal mine communication system, introduced four-layer architecture of the communication system, and described realization of the message middleware technology used in the coal mine communication system. The message middleware provides both synchronous and asynchronous connections between layers of the communication system, and achieves status that data does not loss, not change and not leak during transmission by use of ensuring information transmission technology, message parsing and filtering technology, exception handling technology and Hibernate technology. The testing result showed that the message middleware technology increases data processing speed of the coal mine communication system and reduces error rate of the data.
