针对秦岭北麓浅山区森林火灾监测的需要，设计一种基于无线传感器网络的森林火灾实时监测系统，该系统给出监测实施的网络体系结构、无线传感器网络节点的硬件设计和软件实现。同时，针对无线传感器网络的能量约束问题，提出基于网格理论的节能算法，该算法以中心点的计算代替原有四周节点的计算，降低了计算复杂度。仿真结果表明，计算覆盖度与实际覆盖度的误差小于11%，验证了算法的有效性。

This paper designs a forest fire detection system based on wireless sensor network. The hardware and software circuit were designed, as well as the system architecture of sensor network was described also. Meanwhile, because of the wireless sensor networks’ energy constrained, energy-saving algorithm was proposed based on grid theory in this paper. The algorithm calculates the center point instead of original four surrounding nodes and the complexity is reduced. The simulation results show that the degree of error between the calculated coverage and actual coverage is less than 11%, verify the effectiveness of the algorithm.
