Design And Implementation Of The Mobile Base Station Status Remote Data Monitoring System

With the increasing of wireless coverage of mobile networks, the construction scale of base stations and the monitoring room is growing. Meanwhile, the job of electricity using information managing in site and environmental monitoring are onerous day by day. It is an irresistible trend that the maintenance and management of base stations and monitoring room will be unattended, centralized, automated. The monitoring system is an important support and tools of maintenance and management of base stations and the monitoring room, and it has became the basic package need in base stations and monitoring room construction. Therefore, the introduction of a new generation,functional and intelligent control system has an important significance.Based on the above considerations, the thesis designs a remote data monitoring system which takes GPRS as the main means of communication. The system takes the AT89C51 Series MCU as the core of data collection terminal, and uses GPRS wireless to upload the collected environmental data to the remote data monitoring centre in real time. The data monitoring centre is prepared by the VB language. It provides a friendly user interface. Though connecting with the background SQL 2000 Server database, it displays the received data by real-time curve, and automatically stores the data into the history database preparing for query. The monitor center realizes the level-to-level administration to the user, establishes the different user operation jurisdiction, enhanced system's security. This kind of data collection terminal may distribute massively in the monitor scene. It doesn't need the wiring, but it can move at will, and can gather the environmental data on fixed time. It also can transmit the simple control command. It overcomes low monitor frequency and the low transmission speed of the traditional wired way.The test shows that every parts of the system can meet the requirements of the original design. It makes the remote wireless transmission of small-mass and non-continuous data realized. It offers a convenient wireless data transmission method for present data collecting system, which can take place of the existing cable remote monitoring system. Moreover, the terminal has several standard I/O channels. The system's scalability is very strong.
