基于瑞萨单片机的智能限电、防雷和防火控制器设计

Design of Intelligent Power Rationing,Lightning Protection,and Fireproof Controller Based on Renesas MCU

为避免学生宿舍内因使用大功率违章电器导致用电线路过载过热而引发火灾等隐患和漏电导致的接地、电孤短路等引起火灾事故,设计了以瑞萨单片机为控制核心的用电安全控制系统。系统从用电源头自动识别、防止学生宿舍违章恶性负载的使用和实时检测线路漏电等情况的智能控制。调试结果证明该系统在保障学生宿舍的用电安全(限电功能、时间控制、人身触电、防雷安全、防火安全)方面实现了有效的控制,该项智能控制器的研究及开发应用对维护学校安全稳定具有较为显著的现实意义。

In order to avoid the fire accidents caused by students using high power appliances in dormitory which leads to overload and overheat,and caused due to current leakage which leads to short circuit,a control system is designed using Renesas microcontroller as the core.The system can automatically identify and prevent illegal vicious usage of electricity in students＇ dormitory from power supply source,and real-time detect the load line leakage,etc.Test results show that the system can realize the effective control of the safe use of electricity in student dormitory.The intelligent control has significant practical significance in maintaining the safety and stability of university.
