危险场所基于RFID技术门禁系统设计

危险工作场所对人员数量有着严格的规定，因此需要对当前进出人员严格管理。基于无线射频识别（RFID）技术单通道双向门禁系统利用RFID技术非接触式无线识别的特点，通过对人员佩戴的无源电子标签进行自动识别，获取当前的人员信息，判断其合法性和计算当前区域内的人数决定是否开启道阀或者超员报警，并将人员信息和报警信息上传至信息中心，从而达到对危险工作场所人员的定员管理。本设计给出了系统设计、软件设计，并应用于实践，取得了良好的效果。

Design of access control system based on RFID technology in dangerous workplace

The number of people in dangerous workplace has been limited strictly, so people pass in and out dangerous workplace must be controlled strictly. The design of single-pass two-way access control system based on radio frequency identification （RFID）technology can use the non-contact wireless identification characteristic, identify the information of the people with the passive electronic label, decide to open the gate or excess personnel alarm whether or not from judging the legitimacy and counting the number of people in the dangerous workplace, upload the information of people and alarm, thus achieve the arm of strict rated passenger capacity management in the dangerous workplace. This project gives out the system design, software design, applies to the practice ,and obtains the good effect.
