The Application Of The Short Message In The System Of Wireless Monitoring And Data Collection

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 synthesize the technology of computer, wireless data communication , automatic control, ect. , based in the cosideration of update communication technology according with the traditional industrial, implement a data transmission channel using GSM short message platform, which can meet the requirements of monitoring, dispersing and non-watching of the monitoring collection points, It is also a monitoring collection system with the features of wide covering by net, non-schedueld and unfixed monitoring, and it has the strong points of low investment and low management cost as well. This system has advantages compared with other systems that should meet the requirements as dispered locations of monitoring collection , wide covering , unfixing monitoring, 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.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 shortmessage module and single chip computer effectively, designed a short message single chip computer module -SM02 module, and gave out the arithmetic of realization of module SM02.The writer also finished and realized the techniques as the distance shingle chip computer data collection, communication, data receiving in monitoring center, controlling and computer fetch communication, and described the software module in the monitoring center all-round.In the end , the writer summarized the procticability of system under research, meanwhile , gave out the research directions to this system for perfect and extension.
