| The article mainly introduced develops a set using VB to implement the short information receiving and dispatching function information system, and produced the short information transmission system to be soft, the hardware and the design process, as well as current wireless check development tendency, with present wireless communication close link. This system based on the GSM principle using the handset communication,the long-distance information inspect system, this system has used handset short note long-distance range receiving and dispatching and the monolithic integrated circuit valid union, The most major characteristic is may implement the security long-distance range real-time monitoring, and recording monitoring result, because has used the TC35module, therefore the hardware is relatively simple, Mainly has PC computer, the TC35module, the monolithic integrated circuit as well as between them the serial interface, and carries on programs checks. PC computer and between the TC35module communication protocol pick the GSM general communication protocol, Controlled using VB language MSCOMM to implement two between communication, the monolithic integrated circuit has partially used on the position computer, caused the examination and the prosecution in the different place, guaranteed personnel’s safety, the hardware causes the system run to be more reliable. The paper focuses on describing the correspond process betweet single-chip interface and TC35i modules, TC35i features and main functions, AT command application, the realization of SMS PDU in the single-chip codec, such as program modules. The single-chip of system associated with the TC35i module through a standard serial port to complete the TC35i module initialization and the function of sending and receiving short message,to complete the impression of information betweet single-chip and TC35i module, according to the message, the system drive the implementation to do the corresponding action. |
