摘要
针对配电电缆沟存在的入侵与火灾风险,提出基于两级无线组网的配电电缆沟综合布防系统的设计方案。通过分析与试验,选定适用于配电电缆沟的无线通信频率,采用热电堆红外传感器测量配电电缆沟空间温度,实现火灾早期预警和入侵探测,并提出基于工作井编号的辅助定位方法。通过实际运行验证,该方法可较好地解决配电电缆沟环境信息的采集和传输问题。
In allusion to intrusion and fire risks of power distribution cable trench,a kind of design scheme for integrated de-ployment system of power distribution cable trench based on two-level wireless network was proposed. By means of analysis and experiment,wireless communication frequency applicable for power distribution cable trench was selected. Thermopile infrared sensor was used for measuring space temperature of the power distribution cable trench in order to realize early a-larming on fire and detection on intrusion. An auxiliary positioning method based on work well number was proposed as well. Practical operation verified that this method could well solve problems of acquisition and transmission of environment information of the power distribution cable trench.
