Research On Monitoring And Management System Of Security Equipment Based On ZigBee Technology

Office information in our country has been quite popular, people not only hope this way more efficient and more convenient, but also hope that the information is more secure in the office. The monitoring and management of confidential equipment is the short board of the enterprises and institutions, government agencies, military police department. The traditional monitoring and management system often has the disadvanta ges of complex connection mode,poor maintainability, high labor cost,single monitor ing terminal and low management efficiency.In view of the above drawbacks of traditional monitoring and management system, based on the ZigBee wireless sensor network technology, combined with radio frequency identification(RFID) technology,Wi-Fi technology and embedded linux operating system, this design not only can monitor the confidential equipment int the short and long range, be carried out early warning of danger,but also can manage the confidential equipment, personnel and the authority of the personnel. The main work of this design is as follows:1) Hardware and software platform of the system. This design is based on the ARM platform which is equipped with the Linux operating system as the host computer, the ZigBee wireless network system with zstack-1.4.3 protocol stack and the RFID information collection system as the slave computer.Through the preparation of host computer and slave computer interface adapter software realizes the informa t io n exchange.Through the design of the hardware circuit and the transplantation or preparation of the linux driver, the underlying support of the software and hardware platform of this system is realized.2) Software design of monitoring and management subsystem.Through the preparation of camera, SD card, Wi-Fi and LCD applications, combined with the tracking positioning subsystem and RFID information collection subsystem, this design is able to play the video online,storage the video,playback the video,transmit the video through network and monitor via wireless.Software design for management,using the communication link between the host computer and the slave computer, the function of adding and deleting the confidential equipment and the use of personnel is realized. At the same time, through the association of people and equipment, the management of personnel rights is realized.3) Software design of tracking and locating subsystem based on ZigBee protocol stack. Zstack-1.4.3 protocol stack is the software development platform for this location subsystem. Through the research of zstack-1.4.3 protocol stack application programming framework, the software of the reference node, the blind node and the routing node of the positioning subsystem is implemented. The method of least square estimation and cc2431 location engine is used to realize the tracking and locating algorithm.
