在这个日益发达的社会，各种公共场所越来越多，所能容纳的人数也越来越多，这给这些的场所的管理带来了许多不便。如果有种设备能对出入这些场所的人进行统计，那么对这些的地方的管理将带来很大的方便。
这篇文章中详细介绍了一种公共场所监控系统的制作方法，从各元件的选择到电路的设计，从硬件到软件都进行了详细的介绍。该系统采用单片机AT89S52进行控制，大大简化了外围电路的设计，系统结构简单。同时，该系统可以进行很多扩展，如实现多机通讯，可对更大的场所进行监控等。
该系统可以显示当前时间，设置该场所允许进入的时间。如果在禁止进入的时间里有人进入该场所，那么系统将进行报警。

In an increasingly prosperous society, many more and more public spaces, can accommodate the number of many more and more, which give the management of these places has brought much inconvenience. If endemic equipment traveling to and from these places for people to statistics, then the management of these places will bring great convenience.
This article describes in detail a monitoring system in public places production methods, from the select components to circuit design, from hardware to software has made a detailed introduction. The system uses single-chip AT89S52 control, greatly simplifying the external circuit design, system structure is simple. At the same time, the system can be a lot of expansion, such as the realization of multi-machine communications, may be greater monitoring sites.
The system can display the current time, set the time allowed to enter places. If at the time banned from entering someone to enter the premises, then the system will alarm.
