Design Of Entrance Guard And Monitoring System On Communication Base Based On Short Message

Nowadays, with the increasing number of mobile telephone consumers in China, the load and number of communication bases would increase. In order to reduce the maintaining cost and guarantee the communication quality, the operating information of communication bases and the information of entrance guard must be watched in time.Now, expensive fibre is widely used in the monitoring system of communication bases. It is not suitable for the plentiful and widespread medium-mini bases. Most of medium-mini bases still stay on the level of manual operation.Firstly, the paper introduces the necessity of entrance guard and monitoring system on communication bases. Secondly, the monitoring systems based on Short Message and wired network are compared. Finally, for the need of medium-mini communication bases, a new monitoring system based on SM is designed. It is suitable specially for the alarm of unusual situation, the monitoring of environmental information and entrance guard information.The system is composed of the monitoring terminal and monitoring center. Communication between the monitoring terminal and the monitoring center is carried on short message. The paper involves the following main technologies: SM coding, sensor, database, serial communication, RFID, SCM and Visual C++ etc.Testing results indicate that the access control and environment monitoring of the medium-mini communication bases are achieved by the system. The system has many advantages such as good stability, and so on.
