摘要
以单片机AT89C51为核心,采用光电感应器和单片机系统的技术测量控制装置,同时利用红外装置采集信息,并将信号进行放大形成对应的高电平信号通过LED显示反馈人数,从而达到管理的目的。文中对基于单片机的教室人数自动统计系统和软件系统进行了设计和规划,其中硬件设计主要包含主控、计数显示、红外检测和电源等模块,阐述了教室人数自动统计系统在管理中的实现过程。文中设计的系统能较好地实现教室人数自动统计功能,因此具有一定的使用价值和应用前景。
With single chip microcomputer AT89C51 as the core, we use photoelectric sensor and single-chip microcomputer system of technology measurement control device. At the same time, the infrared device is used to collect information, and the signal is amplified to form a corresponding high level signal through the LED to display the number of feedback, so as to achieve the purpose of management. In this paper, the design and the planning of the automatic statistics system and software system based on MCU are designed and planned. The hardware design mainly includes the main control, counting display, infrared detection and power supply module, the number of classroom automatic statistical system in the management of the implementation process. The system designed in this paper can realize the classroom number automatic statistics function well,so it has certain application value and application prospects.
