摘要
针对预装式变电站户外运行时内部电器设备容易受到外界环境影响的现状,提出了一种对预装式变电站内温湿度烟雾进行在线测量的WSN传感器节点设计方案。考虑到传感器节点工作环境电磁干扰严重,采用非阻塞方法设计程序;同时以Jennic的JN5139无线微控制器为处理器核心模块,最大程度地提高抗干扰能力。详细介绍了节点硬件各部分组成和软件流程设计。实测结果验证了该传感器节点具有功耗低、性能稳定等特点。
When prefabricated substation is operating outdoor, the internal electric equipment is easily affected by external environment; aiming at this situation, the design scheme of the WSN node that can be used on line for measurement of temperature, humidity and smog in prefabricated substation is proposed. Taking into account of the serious electro-magnetic interference in working environment of the sensor nodes, the design procedure with non-blocking method is adopted; in addition, the wireless micro-controller JN5139 of Jennie is used as processing kernel module, thus the anti-interference capability is enhanced in the maximum extent. The compositions of each node hardware part and design of software process are introduced in detail. The result of practical test verifies that the sensor node possesses features of low power consumption and stable perfommnce.
