Base Station Inspection And Computer Room Environment Monitoring System Terminal Design

Patrol work is very important in safety equipment maintenance of base station. To overcome the shortcomings of the traditional patrol work and to increase the convenience and availability of patrol work, the thesis summarizes others work and improves the original patrol management programme. And the thesis designs a system terminal called "Intelligent patrol work and environmental monitoring system (BVSTM) terminal ". Though this system transmits, we can complete patrol work and achieve environmental monitoring of the base stations at the same time.According to the steps of engineering development, the users' requirements are analyzed and the functional figure is given in this thesis. Then the detailed designs of every step are given, and the all hardware composition and the flow charts of the whole system terminals are showed in the thesis.The main contents include:1. A system based on the GSM wireless communication is designed in this thesis.It transmits patrol data, monitoring data and warning messages through receiving short messages (SMS). The thesis constitutes the communication protocol between the base station terminals and management center, which is the standard format criterion and ensure the stable and reliable communications. In addition, the thesis studies the problems about the short lapes messages and provides a solution.2. The thesis designs an access system based on radio frequency indentification technology, which unlocks and seizes patrol data through reading cards. The system can ensure the security and make the base stadion management more standardized.3. With time series simulation software, the CPU's I/O ports simulate I2C bus and exchange data with clock chips, temperature humidity sensors, memory chips and other devices. E2PROM memory space is distributed reasonablely and in detail. Date can be stored and transfered more conveniently.The thesis also designs the municipal electricity blackout and alarm circuit, the AC (Air Condition) switching control circuit, the watchdog circuit, the LCD display circuit, real-time clock circuit and the serial communication testing circuit.
