The Design Of EMU Smoke Monitoring System Based On ZigBee

With the rapid development of wireless communication technology, wireless transmission has been widely used in various industries, especially ZigBee technology rises more rapidly development in the2004.ZigBee technology is an emerging wireless network communication technology, which is based on the IEEE802.15.4standard established and defines a medium access protocol architecture layer and physical layer, due to its low-cost, short-range, low-power and low-rate wireless communications market to fill the gaps in the field.The combination of the ZigBee wireless technology and EMU smoke control systems can be achieved with more nodes, more timely monitoring of the presence or absence of fire safety hazards EMU. In this article, establishing through the use of ZigBee wireless sensor networks and achieving real-time wireless smoke collection and monitoring functions. According to the characteristics of ZigBee network protocol, we first optimize the system of choice for wireless sensor networks to ensure that data can be promptly reported; Then we finish nodes to achieve the smoke hardware circuitry and software functionality, using PIC16F630and detectors perform the data acquisition and processing done by CC2430chip data communication to transfer wireless sensor networks; Finally, the ZigBee network is successful built and realized the application of wireless transmission technology for smoke monitoring system in the EMU.From the whole system design suggestion, it has not many system variable parameters, so the micro-controller of PIC series was choice. The idea of modular was used to design the circuit in order to realize the functions of smoke detectors, alarm devices and so on. And the software functional achieve was based on the embedded development technology. In the system, C programming language was use to build the software, for it has good readability.
