随着高速公路的快速发展,长大隧道日益增多,隧道内大功率风机、照明设施、可变信息标志、视频监控设施等非线性负载的大量应用,使供配电系统的电能质量问题日趋严重,设备损坏的频率也日渐增多。为了保证隧道供配电系统的安全运行,以及以后更好的维护供配电系统,需要对供配电系统进行实时监测。本文设计了以LPC2103为核心的高速公路隧道供配电系统测控装置的硬件结构、软件实现流程,并对应用情况进行了分析。
With the rapid development of expressways, the number of long and large tunnels is increasing. The large number of applications of non-linear loads such as high-power fans, lighting facilities, variable information signs and video monitoring facilities in tunnels have made the power quality problems of power supply and distribution systems worsened day by day , The frequency of equipment damage is also increasing. In order to ensure the safe operation of the tunnel power supply and distribution system and to better maintain the power supply and distribution system in the future, it is necessary to monitor the power supply and distribution system in real time. This paper designs the hardware structure and software implementation process of the monitoring and controlling device of expressway power distribution system taking LPC2103 as the core, and analyzes the application situation.
