2、thic 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 pro

3、duced 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 network1 Summarize:Along with correspondence technique of development, according

4、 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 shor

5、t 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

6、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.2 The application of GSM network:GSM is Global System for Mobile Communications acronym, which means Global System for Mobile Communica

7、tions is the worlds leading cellular systems in the world. GSM is based on narrowband TDMA standard that allows radio frequency in a group call at the same time 8. GSM80 during the rise in Europe, put into use in 1991. The end of 1997, has operations in more than 100 countries, Europe and Asia has b

8、ecome the standard in fact, that by 2001, the worlds 162 countries have already built a 400 GSM communications network. But the GSM system capacity is limited, users in the network overload, it had to construct additional network facilities. What is gratifying is that GSM performance in other areas,

9、 which in addition to providing a standardized list and signaling systems, but also opened up some of the more intelligent of the business such as international roaming and so on. The convenience of GSM mobile phone is that it provides a smart card, known as SIM cards, and card could be separated, s

10、o that the replacement of mobile phone users and custom personal information in this area are facilitated.GSM network to improve after years of development, is now very mature, less blind spots, signal stability, automatic roaming, and the communication distance from the impact of the surrounding en

11、vironment. GSM short message in particular, flexible and convenient, you can cross-market, inter-provincial and even cross-border transmission, and each send a short message as long as one dime, very reliable and affordable. In addition, the mobile phone SIM card in recent years can apply for 0, som

12、e packages use lower cost than fixed. Therefore the use of mobile phone message to achieve alarm, ultra long-range remote control for industrial equipment, transmission of data is a very good choice.GSM module, is a similar mobile communication module, integrates a number of mobile phone functions o

13、n a single small circuit board, it can send SMS messages, calls and so on, the module is small, but it has a lot of mobile phone functionality, with its have equal is the core of the mobile phone, and it is in a lot of applications have a wide range of applications, GSM module through the use of AT

14、commands to control it, modules can be connected to computer RS232 serial port, can also be used to carry out single-chip control . Below we cite some typical applications:2.1 mobile phone access control system: GSM Access Control System used to control the electric lock control, if you need to ente

15、r, as long as the cell phone call using GSM modules mobile number, will automatically open the door, and only you can set up cell phone numbers to open the door, and no costs.2.2 three billboard over the weather disaster emergency turn off: Over three billboards are constantly flip through the motor

16、 to achieve a number of ads displayed, because installed in the outdoors, when there is wind, hail and other weather disasters, billboards could easily be blown bad or damaged card die, when in need of emergency shut down, You can normally closed relay contact to control the power of advertising, wh

17、en you need to do is send turn off control message, the billboard will automatically turn off, and automatically after a certain time delay automatically return to normal job (generally disastrous weather will not continue for a long time) in advance if you want to open a billboard, you can send Ope

18、n control message.2.3 engineering system balance reminders:Some works are safe after the completion of the normal operation after a period of time to settle the balance, if the encounter malicious clients the outstanding purchase price, often installed side very headache, because equipment has been

19、installed, if the loss of a great come back down, particularly in the field customer very costly when the client system can be installed in the GSM module, use it all the way to control system or the way some of the key points, when the customer paid in arrears when the malicious message can turn of

20、f some features, forcing customers to pay the purchase price then immediately open message, if you have a smooth recovery of the purchase price can also be the name of system maintenance by the GSM module removed from the client system. 2.4 monitoring systems or Web servers and reset the alarm:Monit

21、oring system or web server running after a long period after death may be wrong, this time to power on reset is the only solution at this time through the GSM module can control system power, and set to open automatically after 3 seconds turn off mode, can achieve power reduction, in addition, GSM m

22、odule in some special application areas also played a very large role, such as: the disappearance of the main power supply, memory errors, fan shutdown, fuel depletion, it was the invasion and other information, are not people the ideal choice for monitoring the engine room. 2.5 the remote control o

23、f home appliances:Through the message can easily achieve the remote control to open rice cookers, water heaters and other appliances by remote control or switch to repair mode can also control the air-conditioning GSM global wireless mobile communication network control alarm host, using the global

24、GSM short message data transmission mode and voice-enabled platform for the completion of intelligent data transmission and remote control alarm, set the host family, shops, office safety, electrical control, remote monitoring, such as Intelligent home functions, because of the global GSM wireless m

25、obile communication network signal coverage area of Canton, and truly realize the low-cost high-quality ultra-long-distance convenient and flexible intelligent wireless control and alarm, to solve the fixed-line telephone or cable broadband network wired alarm limitations. GSM global wireless mobile
