Abstract
This article through analyzed the GSM module and the monolithic integrated circuit connection design simply introduced the TC35i module commonly used instruction and the coding rule, introduced emphatically the TC35i module and the AT89C51 principle of work, the periphery connection electric circuit, the software control technology, at the same time has produced some TC35i module and the AT89C51 connection application procedure, proposed AT89C51 when receive data should pay attention question, thus designed has the GSM module the data transmission terminal.

Key words: GSM network
1 Summarize:
Along with correspondence technique of development, according to the service function of the NTT DoCoMo net, just to industry control and control from a distance the realm have continuously extension of trend.Is orientation this kind of demand, Siemens company released a new generation wireless correspondence GSM mold piece-TC35i, according to should the short news function of the mold piece, can fast safety credibility realization customer information processing etc. function, special be applicable to control centre and terminal equipments distance very far, or inconvenience adoption wired correspondence lie quality etc. situation, for example the oil well information collect behind of deliver, the long range copy form system, city transportation direction etc. all according to the TC35i mold piece to realization.
摘 要

本文通過分析 GSM 模塊與單片機(jī)的接口設(shè)計(jì)簡單介紹了 TC35i 模塊的常用指令及 摘 編碼規(guī)則,著重介紹了 TC35i 模塊與 AT89C51 的工作原理、外圍接口電路、軟件控制技術(shù), 同時(shí)給出了一些 TC35i 模塊與 AT89C51 接口的應(yīng)用程序, 提出了 AT89C51 在接收數(shù)據(jù)時(shí)應(yīng) 該注意的問題,從而設(shè)計(jì)出具有 GSM 模塊的數(shù)據(jù)傳輸終端。

1 概述:
概述 隨著通信技術(shù)的發(fā)展, 基于移動(dòng)通信網(wǎng)絡(luò)服務(wù)功能, 正向工業(yè)控制和遙控領(lǐng)域有不斷擴(kuò) 大的趨勢。為適應(yīng)這種需要,西門子公司推出了新一代無線通信 GSM 模塊——TC35i,基 于該模塊的短消息功能, 可以快速安全可靠地實(shí)現(xiàn)用戶信息處理等功能, 特別適用于控制中 心與終端設(shè)備距離很遠(yuǎn),或不便采用有線通信介質(zhì)等場合,例如油井信息采集后的傳輸、遠(yuǎn) 程抄表系統(tǒng)、城市交通導(dǎo)向等均基于 TC35i 模塊來實(shí)現(xiàn)。
2 GSM網(wǎng)絡(luò)技術(shù)的應(yīng)用:
GSM是Global System for Mobile Communications的縮寫,意為全球移動(dòng)通信系統(tǒng),是世界上主要的蜂窩系統(tǒng)之一。GSM是基于窄帶TDMA制式,允許在一個(gè)射頻同時(shí)進(jìn)行8組通話。GSM80年代興起于歐洲,1991年投入使用。到1997年底,已經(jīng)在100多個(gè)國家運(yùn)營,成為歐洲和亞洲實(shí)際上的標(biāo)準(zhǔn),到了2001年,在全世界的162個(gè)國家已經(jīng)建設(shè)了400個(gè)GSM通信網(wǎng)絡(luò)。但GSM系統(tǒng)的容量是有限的,在網(wǎng)絡(luò)用戶過載時(shí),就不得不構(gòu)建更多的網(wǎng)絡(luò)設(shè)施。值得欣慰的是GSM在其他方面性能優(yōu)異,它除了提供標(biāo)準(zhǔn)化的列表和信令系統(tǒng)外,還開放了
