Research on Online Monitoring and Remote Alarm System for Elevators

LIU Song-guo,HAN Shu-xin,LI Wei-zhong,WU Bin(Hangzhou Special Equipment Inspection Institute,Hangzhou 310003,China)  
According to the aging of elevators which causes fluquent problems,online monitoring system of running status was researched and remote alarm of elevators' problems was realized.Based on Mega MCU,embedded system with high cost-effective was designed,which gets the running speed,direction,floor,door switches and passenger status through the method of multi-sensor information fusion.Reasoning strategy was researched and exploited to determine whether elevators were running normally,and deduce fault type when unnormally.Bi-direction data transfer between RS485 and Ethernet was developed to establish communication for online runnning status monitoring system with remote management platform,based on which,centralized monitoring and automatic remote alarm of elevators were accomplished.The proposed system supplies technical support for safety supervision of elevators,and practical operating results prove its effectiveness.
