摘要
设计主要用于教室人数及空座位数实时显示。单片机接收红外线检测装置的信号,对数据进行处理后人数显示到LED点阵;然后中心单片机综合处理每间教室数据,在LCD显示屏上发布教室实时人员信息,这样便于学生进行远程选择。经测试,该系统具有成本低,稳定性高的特点,可以广泛用于高校教学楼、图书馆的人数计数。
This design is mainly used to display the number of students and empty seats in classroom anytime.MCU receives the signal of infrared sensing device,once process data,the information about men will display on the LED lattice.Then data of every classroom are coped by center SCM comprehensively,real-time personnel information will be released on the LCD,so it is convenient for the students to perform remote selection.
