摘要
针对施工升降机在安全监控方面存在的问题,以及嵌入式系统中程序存储空间小需要对指纹算法进行改进与简化,提出了一种新的基于三角形面片的快速匹配算法识别的嵌入式施工升降机安全监控系统设计方法,使用新的指纹匹配的算法,减少了基准三角形对选取的时间,提高了指纹匹配的速度,以及使用STM32F103处理器和FPS200指纹传感器构建算法的嵌入式系统,成功实现了嵌入式施工升降机的安全监控的功能;指纹识别的准确率达到95%以上,具有很强的实用价值。
According to the problem of safety control of the construction elevator, and embedded systems program storage space is little, need for fingerprint algorithm was improved and simplified. This paper proposes an embedded construction elevator safety monitoring system design method of a new fast matching algorithm based on triangle patch. Using a new fingerprint matching algorithm, to reduce the triangle select time, improve the speed of the fingerprint matching. And using the STM32F103 processor and FPS200 fingerprint sensor construct the embedded system of algorithm, successfully realized the function of safety monitoring of the construction lifter. Fingerprint identification ac= curacy of more than 95%o, has a strong practical value.
