Development Of The Short Message Issue System

Mobile short message has become a method to obtain information for users because of its low cost, bidirectional transmission, reliable quality and rapid speed .According to the accessing mode, there are three major methods: The first method is connecting the China mobile or Unicom short message center or short message gateway by internet or special line. The second method is connecting the short message center of central operator by internet or special line. The third method is using communication equipment and PC to build the short message center of oneself. According to different connecting method, the research of short message software and hardware system and its application mode is one of the key question nowadays.According to the practical demand, this system uses the third mode. This thesis based on a large number of related documents, and short message release platform based on the third way of receiving is proposed. In this thesis a new kind of short message receiving and sending equipment and application software. The equipment includes hardware design and software design. The hardware part is a piece of circuit board including the mobile phone module, MAX3237 etc. The circuit board connects with computer with serial interface (USB interface) to transfer the data and realize the receiving and sending the information. Because the magnet antenna is fixed, the system has higher anti-interference ability and sensitiveness, and more stable signal. The software part provide a friendly interface for the customer, and it is convenient for the customer to receive and send message, customer management, system management and statistics analysis, especially the receiving and sending of community information and its management. The software part also realizes the functions of excess group sending, adjustment of receiving and sending efficiency, information queued, and information management. By the test experiment, the developed system reached the demand of, and meanwhile the application model is further proposed.This subject belongs to the enterprise principal project. The short message release platform researched in this thesis is in order to solve the problems of the weak anti-interference ability, the slow speed of data transmission, and the platform can not realize the commercialization and industrialization. The software and hardware system of short message release platform is designed and realized. The system is used in the real application of user service and office automation, and makes a foundation of the further research of remote data collection and monitor equipment.
