Research On Lift Passagers Monitoring System Based On Android Platform

With the development of economy and the acceleration of urbanization,high-rise buildings are emerging everywhere,driving the rapid development of elevator industry.Nowadays,elevators have become the first choice for high-rise building users to travel,and the elevator monitoring system is an indispensable part of it as the supervisor of elevator operation status.The traditional monitoring system generally adopts the manual monitoring method,the disadvantages are its low efficiency,low flexibility and high maintenance cost,which can no longer meet the elevator’s demand for monitoring system.Therefore,designing an intelligent elevator monitoring system with stable performance and intelligent video analysis not only has practical application value but also broad market prospect.In this paper,we design an intelligent elevator passenger monitoring system based on Android technology.The research content of the paper mainly includes three parts: the design of the elevator data acquisition camera,the design of the embedded platform to drive the camera and the design of the monitoring system client.Firstly,based on the operation principle and structure of the intelligent monitoring camera,this paper designs and produces the hardware of the monitoring camera system according to the image sensor circuit,data transmission interface circuit,clock circuit,power conversion circuit and other modules.Secondly,this paper adopts the ARM terminal with Contex-A53 as the core as the embedded platform,and completes the driver design of video image acquisition device based on V4L2 driver framework of Android system to realize the image acquisition function of surveillance camera.Then,this paper researches the irregular behavior of passengers riding elevators,and realizes the detection and early warning of dangerous behavior of passengers riding elevators in violation based on SSD target detection algorithm.Finally,the human-computer interaction interface is designed based on the Android Studio development platform to facilitate the optimization and testing of the system.Based on the above work,this paper finally completes the design of intelligent elevator monitoring system.The system can not only realize the function of elevator passenger monitoring all day and all the time,but also monitor and warn the dangerous behaviors of passengers in the elevator intelligently and reduce the work intensity of security personnel.The actual test results show that the system has the advantages of good stability and accurate detection algorithm,and at the same time,compared with other similar products,the system is small and expandable,which improves flexibility and reduces application costs,and has certain practical value in today’s widespread application of intelligence.
