矿井人员定位系统中标识卡唯一性检测装置设计

针对矿井人员定位系统对出入井人员不带卡、多带卡、替代卡等行为检测手段单一、准确率低的问题,设计了一种基于人像识别技术的标识卡唯一性检测装置。出入井人员通过该装置时,安检门自动扫描人员脸部特征信息,并把扫描信息上传至检测主机进行判断,如发现人员携带超过一张卡,检测主机则立即下发命令进行声光报警;否则,进行快速人像识别比对。实际应用表明,该装置能够快速判断出入井人员不带卡、多带卡、替代卡等入井行为,具有较高的稳定性和识别率。

Design of Marking Card Uniqueness Detection Device in Mine Personnel Location System

In view of problem of single detection method and low accuracy for behaviors of no card,multi-card and substitute card of out-in personnel in mine personnel location system,a marking card uniqueness detection device based on face recognition technology was designed.When the personnel pass by the device,security inspection door scans face feature information of personnel automatically and sends the information to detection host.If finding the person carries multi-card,the detection host immediately downloads command to make sound and light alarm,otherwise the detection host makes quick face recognition comparison.The actual application showed that the device can quickly judge behaviors of no card,multi-card and substitute card of out-in personnel and has higher stability and recognition rate.
