The Design And Implement Of 800M TETRA Water Inspection System By Tianjin Water Conservancy Burea

With the development of PMR, more and more company and institution join in thereaserching of Trunked radio sytem. In China, the Trunked radio system study is takingon a new flourishing looking.The paper probes into the water inspection system using 800M TETRA by Tianjinwater conservancy burea and the technology of TETRA. The destination is to design aproject based on NOKIA/SIMOC TETRA system fitting for water informationinspection.The analysis of TETRA protocol is the foundation of the article, as well as thedesign of the whole system. In particularly, the part of Air interface specification isreally essential, because Chinese Trunked Industry standard refers to this one. Byanalyzing, we can easily distill the protocol stack needed for our project. After that, wecan upbuild the whole hierarchy of system design.The design for water infprmation system is the most import part of the paper.Considered the needs, and the condition has been provided by Tianjin waterconservancy burea. Meanwhile taking account the advantages and disadvantages ofTETRA into, the paper establish the blue print for water inspectin system. In addition,the article focuses on the discussion of the system foundation process, introduces thesystem hierarchy, also.The development and design of software and hardware is the basic content in thepaper. The most content including: Data terminal hardware, SDS data transmitionsoftware, water information server processing software. As for the hardware design, Iuse AVR/Mega128 single machine as the basic processor. On the other hands, thesoftware technology, such as, "dll"and "com", are used for softerware design. The realsystem has been tested, and now it is operatring on Tianjin water conservancy burea.In addition,the article discussion one solution for TETRA termianl,and usingSCM to stimulate and analysize the possibility of th solution.
