现有的射频卡门禁系统，采用的一般是RS 485等有线数据传输方式，这些传输方式存在布线困难、维护成本高等问题。为了克服上述缺点，基于PTR2000无线传输模块构建的智能小区门禁系统，采用无线传输方式代替有线传输方式，满足无线管制的要求且无需使用许可证，实现主控设备与PC机的信息交互。通过实际测试，采用20 Kb/s数据传输率，在有障碍物的情况下，无线通信模块PTR2000可在10 m范围内准确识别。该系统减少了施工难度，利于日后管理者对门禁系统的改造，实现了计算机对智能小区出入口的管理。

In existing access control system,the general wired data transmission is RS485. However,the transmission way has problems of wiring difficulties,high maintenance cost and so on. To overcome the disadvantages,an intelligent access con-trol system is established based on PTR2000 wireless transmission module,which use wireless transmission to replace wired transmission. The system can meet the requirements of wireless control without using license,and realize the information interac-tion between main control device and the PC machine. Through the actual test for PTR2000 module,when data transmission rate is 20 Kb/s and in the obstacle condition,it can accurately identify in 10 meters scopes. The system reduced the construc-tion difficulty,which is good for renovation of the access system for future managers. It also achieved the computer management of import and export of intelligent community.
