Abstract:

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 accuracy of more than 95%, has a strong practical value.
