17、tion get up very easy, but the biggest weakness be to can't receive and dispatch Chinese message;But PDU mode not only support Chinese message, also the ability send out English message.The PDU mode receive and dispatch a message can the usage be 3 kinds of to code:7-bit, 8-bit and UCS2 code.7-t

18、he bit code to used for send out common of ASCII character list, 8-bit code Be usually used for sending out data news, UCS2 code used for sending out Unicode character list.General PDU's code is constitute by ABCDEFGHIJKLM 13. A:The address length of the message center, 216 enter to make number(

19、one word stanza)B:The number type of the message center, 216 enter to make number. C:Message center number, B+C length will from the data decision in the A. D:Document head word stanza, 216 enter to make number. E:Information type, 216 enter to make number. F:Drive call number length, 216 enter to m

20、ake number. G:Drive call number type, 216 enter to make number, take value together B. H:Drive call number, length from data within F decision. I:Agreement marking, 216 enter to make number. J:The data code a project, 216 enter to make number. K:Term of validity, 216 enter to make number. L:Customer

21、 data length, 216 enter to make number. M:Customer's data, its length from the data decision in the L.Enactment in J adoption UCS2 code, here is the Unicode character list of Chinese-English. 3 the hardware of the TC35i and list slice machine connect a people's electric circuitThe TC35i mold

24、itution the TC35i mold piece of work mode:AT+CMGF=n, n=0 is a PDU mode;N=1 write an article this mode;Usually the constitution is a PDU mode, under this kind of mode, ability transmission or accept a transparent data.(customer from definition data)AT+CMGR=n in order to read the short news data of th

25、e TC35i mold piece, the n is a short news number.AT+CMGL=n in order to list the short news in the TC35i mold piece, n=0 is the short news which read, n=a the short news which have been already read, n=2 short news which sent out, n=3 for have already send out of short news n=4 is all short news.AT+C

26、MGD=the n is the short news which delete the TC35i mold piece and the n is a short news serial number. 4 Master routine The software plait distance pass to write in toward the TC35i dissimilarity of AT instruction ability completion variety function, such as network debarkation, read SIM card top te

27、lephone number, send out SMS news and receive SMS news etc. The instruction sign, constant, PDU data.etc. of AT instruction all code form transmission by ASCII;The transmission transparent data have to pair of the TC35i mold piece of work mode constitution is PDU mode;List slice machine toward the T

28、C35i mold piece after send out each instruction have to with return to car sign conduct and actions should instruction of be over, for example list slice the machine send out instruction in"AT+ CMGF=0" toward the cellular phone, its ASCII code sequence is"41 H, 54 H, 2 BH, 42 H, 4 DH,

29、 47 H, 46 H, 3 DH, 30 H, 0 DH", the last word stanza 0 DH is to return to car sign, mean that instruction be over, if have no this to return to car sign, the cellular phone won't identify this instruction.When the AT instruction which receive to an integrity of the TC35i mold piece after, t

30、he TC35i mold piece not summary execution should instruction, but first just receive of the ASCII of the AT instruction code sequence all anti- send out;(contain 0 DH)Secondly send out a the ASCII which return to car sign with a carriage return sign to code, namely 0 DH with 0 AH;Then performance sh

31、ould instruction. The list slice machine read the PDU data of the TC35i mold piece, originality data should is 16 enter make number, but read back of data still is an ASCII mean of 16 enter make number.So a word stanza of 16 entered to make number and then became 2 word stanza of ASMII code.But the

32、PDU data data word stanza length within pack part still is actual character list length.But isn't the word stanza which become ASCII code length, this at plait distance should special attention, otherwise receive of data not integrity.The list slice machine is after receiving a PDU data pack dat

33、a have to its instauration become 16 enter make a data, its calculate way as follows:Establish a for the ASCII code receive, b for the conversion is behind of 16 enter make number.So if a<39 H, b=a-30 H;If a>39 H, b=h-07 H a-30.End pair of in front and back two pieces merger is a word stanza.

34、5 Concluding remark The usage cellular phone mold piece benefit is at the system integration, the cost be lower.Install correspondence circuit in secluded region etc. difficulty or uneconomical place, engineering service facilities can freedom vivid of constitution, no longer be subjected to geograp

35、hy condition of restriction.In fine, GSM mold piece the price be cheap, application extensive, application the foreground be captivating, pass with cellular phone mold the piece connect can very convenience of design customer demand of the data receive terminal. 基于GSM模塊與AT89C51的接口設(shè)計(jì)及應(yīng)用摘 要 本文通過(guò)分析GSM模

36、塊與單片機(jī)的接口設(shè)計(jì)簡(jiǎn)單介紹了TC35i模塊的常用指令及編碼規(guī)那么，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(wèn)題，從而設(shè)計(jì)出具有GSM模塊的數(shù)據(jù)傳輸終端。 關(guān)鍵詞 SIM卡 GSM AT指令 TC35i AT89C51 1 概述： 隨著通信技術(shù)的開(kāi)展，基于移動(dòng)通信網(wǎng)絡(luò)效勞功能，正向工業(yè)控制和遙控領(lǐng)域有不斷擴(kuò)大的趨勢(shì)。為適應(yīng)這種需要，西門(mén)子公司推出了新一代無(wú)線(xiàn)通信GSM模塊TC35i，基于該模塊的短消息功能，可以快速平安可靠地實(shí)現(xiàn)用戶(hù)信息處理等功能，特別適

37、用于控制中心與終端設(shè)備距離很遠(yuǎn)，或不便采用有線(xiàn)通信介質(zhì)等場(chǎng)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(lái)實(shí)現(xiàn)。 2 TC35i模塊介紹 目前，國(guó)內(nèi)已經(jīng)開(kāi)始使用的GSM模塊有很多，而且這些模塊的功能、用法差異不大。本設(shè)計(jì)采用的是西門(mén)子TC35系列的TC35i 。這種無(wú)線(xiàn)模塊功能上與TC35兼容，設(shè)計(jì)緊湊，大大縮小了用戶(hù)產(chǎn)品的體積。TC35i與GSM2/2兼容、雙頻GSM900/GSM1800、RS232數(shù)據(jù)接口，該模塊及射頻電路和基帶與一體，向用戶(hù)提供標(biāo)準(zhǔn)的AT命令接口，為數(shù)據(jù)、語(yǔ)音、短消息和 提供快速、可靠、平安的傳輸，方便用戶(hù)的應(yīng)用開(kāi)發(fā)及設(shè)計(jì)。 2.1 模塊

38、中與SMS有關(guān)的GSM AT指令介紹 GSM引擎模塊提供的命令符合GSM07.05和GSM07.07標(biāo)準(zhǔn)。GSM07.07中定義的AT Command接口，提供了一種移動(dòng)平臺(tái)與數(shù)據(jù)終端設(shè)備之間的通用接口；GSM07.05對(duì)短消息作了詳細(xì)的規(guī)定。在短消息模塊收到網(wǎng)絡(luò)發(fā)來(lái)的短消息時(shí)，能夠通過(guò)串口發(fā)送指示信息，數(shù)據(jù)終端設(shè)備可以向GSM模塊發(fā)送各種命令。與SMS有關(guān)的GSM AT指令如表一所示。GSM AT指令集，是由諾基亞、愛(ài)立信、摩托羅拉和HP等廠(chǎng)家共同為GSM系統(tǒng)研制的，其中包含了對(duì)SMSShort Message Service的控制。 2.2 PDU編碼規(guī)那么 目前，發(fā)送短消息常用Text和
