Abstract


Zigbee protocol is an emerging high-speed development of wireless network technology . Zigbee protocol to meet the thousands of sensor nodes to communicate with each other , and the communication efficiency is very high, primarily due to the energy required for the sensor is small, and between the sensors by stepwise manner passed interact . Meanwhile , Zigbee protocol dormant in the absence of signal transmission to reduce energy consumption , shorter equipment , makes it very power efficient , battery longest useful life of up to 2 years . Zigbee technology has more than some of the technical advantage of the characteristics of widely used in automation and control , sensor networks , as well as short-range wireless connection in the transmission field . Existing centralized monitoring system using wired connection , the human and material resources in the engine room of the system construction cost is relatively high , the use of wireless transmission technology can not only save cost when first built , in the engine room equipment adjustments can also be based on the actual easy adjustment ; wireless transmission equipment plus CDMA network can also remote communication , timely notify the relevant personnel to enhance work efficiency . Designed in this paper based on Zigbee wireless module and CDMA module , combined with the existing urban monitoring system , remote centralized monitoring and management of the dynamic environment of the telecommunications room . System through the introduction of a variety of sensors , remote wireless connection control room equipment , to issue monitoring alarm information via the CDMA SMS to acceptance personnel to improve monitoring efficiency , reduce overall costs ; unmanned engine room centralized monitoring , . This article focuses on the composition of the monitoring system , network architecture , the realization of the communication system hardware and software design , as well as temperature acquisition system based on performance tests . The final experimental results show that the remote monitoring of the system design safe, effective, stable, high availability and reliability .
