The Research On Room Monitoring System For Outdoor Mobile Base Station

The design and implementation of room monitoring system for outdoor mobile base station have been discussed in this dissertation. Usually there is no people in the base station. A monitoring system is needed for guaranteing the safety and reliability of the communication equipment. Information acquisition of the power equipment,air-condition equipment and the environment in the room is fulfilled by the system. Also,the system can communicate with the control center, detect exception and send alarm message, fulfill temperature control in the room and the door control scheme.First, the basic information of the room is introduced including the structure and the equipment inside. Then, the requirement of function and capability are analyzed in detail. Based on these information, the design of the whole system in general is presented.Next, the hardware design and implementation are presented which include the introduction of each circuit module, the selection of implementation scheme for each part and specified circuit design. The hardware circuit is based on AT89C55WD microcontroller and includes memory module, real time clock module, serial communication module, signal acquisition module and output drive module.Based on the hardware design, the software design and implementation are presented. The structure of software in general is designed according to the functional requirement. Then, the implementation of all the modules is introduced in detail which include analog acquisition module, real time clock module, serial communication module, exception detection and alarm module, the module for sending short message, room temperature control module and door control module.At last, several major problems met in debuggment and how to solve them are studied in detail.
