摘   要：火灾对社会安全带来的危害是巨大的，为了提高消防员的灭火能力，日常训练必不可少。目前常用的真火训练，存在隐藏的安全隐患且重复率低，因此国内外对模拟消防训练展开研究，并取得一定成果。为了使模拟消防训练场景更具真实性、更复杂，本文提出多火点控制系统。

本次研究在无线网通信技术上选用ZigBee技术，利用其自组网，低功耗，低成本等特点，来进行对多火点控制系统的网络搭建和通讯功能。在利用PYROSIM软件进行火场模型的设计及仿真，从仿真结果中得出燃烧及蔓延的基本规律，从而总结出多火点控制系统的设计参数。

本次课题主要设计了基于ZigBee无线网络的多火点控制系统，实现了在中小型室内模拟火场的布置，并通过按键对远程节点实施点火通信的功能以及火点之间的蔓延功能。

Abstract：Fire hazards to social security is enormous, in order to improve the firefighters' fire fighting ability, daily training is essential. At present, the use of real fire training, there are hidden security risks and low repetition rate, so at home and abroad to simulate fire training research, and achieved some results. In order to make the simulation fire training scene more authenticity, more complex, this paper proposes a multi-point fire control system.

This study uses ZigBee technology in wireless network communication technology, and uses its ad hoc network, low power consumption and low cost to carry on the network construction and communication function of multi-fire point control system. In the design and simulation of the fire model using PYROSIM software, the basic rules of combustion and propagation are obtained from the simulation results, and the structural framework of the multi - fire point control system is constructed.

The main design of the ZigBee wireless network based on the multi-point fire control system to achieve the small and medium-sized indoor simulation of the fire scene layout, and through the key to the remote node to implement the function of ignition communication and the spread between the fire function.

Keywords: wireless network, ZigBee, PYROSIM, multi-fire point
