摘要
学生宿舍用电的安全、科学管理是高校后勤部门的重要任务。基于安全和规范的原则,宿舍在不同的时间段有不同的用电限制。本文设计的限电装置能够根据具体要求,通过判断电路负载的电压电流相位变化,来识别用电器的类型,达到全天限制发热性违禁电器和夜晚限制计算机等开关性负载的目的,实现安全、可靠、人性化的学生宿舍用电管理。
The safety and scientific management of dormitory electricities is an important task for the logistics departments of universities.Based on the principles of security and specifications,the dormitories at different time periods have different power constraints.The electrical deviceis designed to identify the type of electrical appliances by judging the changing of the voltage and current in circuit based on specific requirements.The electrical device limits the contraband electrical heating apparatus all day and other electrical switch loads like the computer on night,and to realize dormitory electricity management safe,reliably and user-friendly.
