For reducing the rate of false alarm what was the main problem in security monitoring of middle-low cars, multiple redundant methods was proposed to obtain reliable detecting information from the car. The multiple redundant is a method on analytical and determine the signals, it analyzed and determined the received signals that a variety of sensors detecting the same target. Then the information was sent to the owner via MMS. The remote alarm was achieved and the reliability of system was enhanced by rational designing the system, calculating the crystal frequency of wireless communication module and choosing of baud rate. Therefore, the remote monitoring of vehicle by the owner was achieved, and the problems exiting in the traditional alarm system, such as distance limitation and false alarm rate, were solved effectively.

Data Acquisition Module

In order to transmit temperature and smoke signals timely and accurately in the fire alarm system of community, design one kind of wireless fire detection and alarm system, which is based on the wireless communication technology, ZigBee. When acquisition module receive the signals which come from the wireless data acquisition module which connected the room with temperature detection module, and then, send to the nearest backbone transceiver module, the defined center module receive the signals, at last, the signals are local-stored or transferred to fire center by GPRS. This design with the characters of low price, high efficiency and reliable, has a certain market.

To improve the intelligent management of the library, on the basis of manual and information management, new technologies were combined to design RFID wireless network with WSN consisting of nodes. Three modules of literature search positioning system, book whole frame system and automatic borrowing and returning door guard alarm system were mainly explored. The intelligent library system based on WSN and RFID used advanced RFID and ZigBee technology for the optimization and integration of literature resources, service process and management mode of the library. The library automation and intelligent interaction were realized and the concept of people-oriented was given full play to the maximum. The results showed that the intelligent library system based on WSN and RFID could basically realize the intelligent library management. To sum up, the system creates a random library service and management system at anytime and anywhere.
