The Design And Realization Of Wireless Data Terminal Based On TD-SCDMA Private Coal Communication Network

TD–SCDMA Private Coal Communication Network for coal mining enterprises mobileprivate network to the existing commercial TD-SCDMA public system as a benchmark, itsuse advanced technology, and overcome the space is small, complex roadway layout of thecoal mine on the public network products under the small of principles to transfo rm thedesign on the part of the functional modules to be combined to make it meet the requirementsof the underground wireless communication.According to the point of information application and combined with advancedTD-SCDMA communication platform for the communication status of the coal mineunderground, the mine wireless data acquisition terminal based on TD-SCDMA technology isdesigned and implemented. The topic first analyze the functional requirements of the terminal,accordingly select UDP as the transport protocol, and define of the format of sending andreceiving messages. Then, the data acquisition terminal combines with TD private networkand Internet networking solution has been proposed. The terminal selects TD terminal moduleLC6311+as communication platform, and MSP430microcontroller as control unit. The focusdescribes the design of the system software and its implementation process, includingsingle-chip communication section, send and receive data conversion. Finally, build a networkand test the wireless data terminal.The test results show that: TD wireless data terminal designed to fast, reliable datacollection, upload and control center of command receiving and forwarding, suitable for coalmine detection system.
