Concerning severe accidents such as confinement due to failures of lift during its operation,a lift dynamic data acquisi-tion system is designed based on the industrial internet,so as to precisely collect lift data under various operating conditions,remotely monitor the lift confinement result and analyze the reasons.The added smart sensor,acting as a third party,can collect various opera-tion data of the lift in real time,and transmit the data via 4G or 5G gateway to the cloud server.The information exchange among peo-ple,machine and system is realized thanks to the site bus and wireless telecommunication network of the operator,so as to monitor the dynamic operating data of the site lift.The monitoring configuration decision making and analysis system in the cloud server carries out the analysis and makes decisions based on smart confinement algorithm,and push confinement instructions to the lift maintenance sys-tem via application interface,so as to remotely monitor and analyze the confinement result.The pilot application of the system in the city shows that the system is operating stably with good effect,demonstrating that the set design objective is achieved.
