摘 要:为了让高校学生在宿舍中更加安全有效的用电,避免校园由于用电而产生的火灾和触电等事项,本文主要设计一个以单片机AT89C51为核心的宿舍安全用电管理器,能够实时监控电流、电压、功率及电量等一些安全指标。该管理器主要由电能采集模块、单片机处理模块、显示模块及执行模块组成。本设计采用单片机技术、电能应用技术、液晶显示技术,以单片机作为核心控制器,通过数据采集部分将采集到的信号传输给单片机,经过处理后送给显示模块和执行模块。仿真结果表明,在给定参数的限制下,系统能安全快捷地保护整个宿舍电路。此外,该系统具有功耗小、稳定性好、成本低等特点,能很好的应用到高校宿舍中。40514 毕业论文关键词:安全用电;单片机;电能采集芯片;电能保护
Design of Electrical Safety Manager on Student’s dormitory
Abstract:To make college students use electricity safer and more effective in their
dormitory, and avoid issues such as fire disaster and electric shock accidents owing to using electricity on campus, this paper designs a Electrical Safety Manager for dormitories with AT89C51 as the core of microcontroller. The current, voltage, power electricity consumption and other safe indicators can real-time be monitored . The manager was composed of power acquisition module, single-chip processing module, display module and execution module. This design adopts chip technology, energy application technology and liquid crystal display technology. It takes SCM as the core controller. First by transferring gathered signals to SCM by means of data acquisition part, and then send to display module and execution module. The simulation results show the system can shelter the whole room's circuit safely and quickly under the limit given parameters. In Addition, this system has the advantages of low electricity consumption, good stability ,low cost and so on. So it can be well applied to College students' dormitory.
