自习室、图书馆人数监测统计显示系统设计

Design of number monitoring statistics system of study room and library

采用对射型红外传感器进行人数监测不仅开发简单,且大大缩减成本。红外对管人数监测应用了PWM软件调制技术,减少误触发抗干扰能力强,提高了检测系统的准确性。利用多机通信,主机可以随时向从机索取需要的数据,使设备数据更新,灵活性大大提高;利用系统语音报警提示功能,当自习室超过10分钟以上没人时还能实现语音提示和自动锁门。采用模块化设计思想,系统人流检测部分、统计部分、显示驱动部分相互独立利于扩展功能。基于红外传感器的多功能自习室、图书馆人数监测统计显示系统实现了各楼层自习室当前人数在一楼大厅大屏幕的动态显示,从而为同学提供一个更加方便、更加人性化的自习条件。

Using correlation type infrared sensor to monitor the number of people not only makes development simple, and greatly reduces the cost. Infrared tube number monitoring uses software PWM modulation technology, reduces false trigger with strong anti-interference capability, and improves the accuracy of the detection system. Using the muhicomputer communication, the host can at any time ask for needed data from the machine to update the device data, then flexibility is greatly increased. Using the function of System voice alarm prompt, as the study area with no one else more than 10 minutes can realize voice prompt and automatically lock the door. Using the idea of modular design, system testing part of stream of people, statistics, display driver part are independent of each other to extend the functionality. The system realizes the dynamic display on the first floor hall big screen The current number of the study room on floors, to provide students with a more convenient and more humanistic study condition.
