摘要
提出一种农田灌溉设备的防盗报警锁定仪设计方案,运用新型活体指纹传感器LTT-C500较好地实现了访客的真人身份验证,只有在通过身份验证之后才允许灌溉设备正常拆卸。介绍LTT-C500的结构、特征、性能,并阐述基于LTT-C500的报警仪设计方案。测试表明,报警锁定仪的FRR(False Rejection Rate,拒真率)和FAR(False Acceptance Rate,认假率)分别能达1/1000和1/1000000的要求,平均响应时间不超过1/3s,LTT-C500的应用有效减少了指纹手套等仿造指纹盗窃案件的发生。
The design plan of a novel alarm locking system for cropland irrigation equipment was proposed. The fingerprint sensor LTY-C500 was used in the system, with better realization of the legitimate owners of real authentication, only if the authenticate system allows equipments after a normal launch. The structure, characteristics, and performance of a new type of live fingerprint sensor LTI＇-CS00 were introduced. Then, the design plan of the alarm system based on LTr-C500 was expounded. Test suggested that the FRR （False Rejection Rate） and FAR （ False Acceptance Rate） respectively could meet 1/1 000 and 1/1 000 000 of requirements. Average response time did not last over 1/3 sec- onds. The application of LTT-C500 could effective reduce the occurrence of theft case by counterfeiting fingerprint gloves.
