Research And Design On Temperature Data Collection And Wireless Transmission System Based On GSM Short Message

The development of the mobile communication in our country is stepping in a period of fast enlargement. Short message can be as a simple and convenient means of data communication. Its business and application are developing very quickly and widely. The manufactories of communication equipments, ICPs and the runners of telecommunication are all putting into the application and developing of short message heart and soul.The writer synthesizes the technology of computer, wireless data communication, automatic control,ect.,based in the traditional industry, and implements a data transmission channel using GSM short message platform, which can meet the requirement of monitoring and data collection .It is also a monitoring collection system with the features of low investment and low management cost as well. This system has advantages compared with other systems that should meet the requirements as monitoring collection point, and non-strict demand for real-time.The article has described and researched in detail of short message, including its whole process of developing, technology know-how, application nowadays and developing in future, working principle, structure for the centre of short message, as well as its standard and agreement, AT order and also developing research, etc. The main point of article is working principle of short message, the method of its realization, combination between short message and single chip computer, as well as computer how to control the sending and receiving of short message, etc, and apply it into the traditional industrial.This paper mainly discusses "Research and Design on Wireless transmission and temperature data Collection system Based on GSM Short Message", which is introduced according to three functions molds one by one in order.First,it introduces the background of the topic, and also made the simple introduction to the technique that SMS and other topics of GSM involve. Then it introduces the total function and the design frames of Wireless transmission and temperature data Collection system Based on GSM Short Message", and especially elaborates the realization of thesoftware detailedly.Second, paper analyzes the design thought and the realization process of the main function molds in order and in sequence within software, which is the core part of the whole article. Then it makes the simple description to the whole connection to each other of the whole system, pointing out at the same time, that the credibility of transmission is assurance of the whole system .At last paper summarizes the whole system on the structure and functions, generalizes characteristics and existent problems of the whole system design, also puts forward to how to better the existent problems, and carries on the outlook to the future technique development.The writer designed a system structure for wireless monitoring and data collection based on short message. This system structure has obvious advantage in techniques and feasibility. The writer integrated the short message module and single chip computer effectively, and gave out the arithmetic of realization of module MZ28.The writer also finished and realized the techniques of distant single chip computer's data collection, communication, data receiving in monitoring center, controlling interface's communication with computer, and described the module's realization of software in the monitoring center all-round. In the end, the writer summarized the practicability of system under research, meanwhile, gave out the research directions to this system for perfect and extension.
