Description

A multi-dimensional monitoring and collection device for escalator operation information

Technical Field

The utility model relates to the technical field of escalator monitoring, in particular to a multi-dimensional monitoring and acquisition device for escalator operation information.

Background Art

At present, the escalator IoT monitoring system mainly collects data through the main control board, such as Japan's Mitsubishi MelEye elevator/escalator monitoring system, the American OTIS escalator remote monitoring system AES, KONE's ELINK 5.1 elevator/escalator monitoring system, etc.

Mitsubishi MelEye elevator/escalator monitoring system is an elevator monitoring system developed based on web technology. The system supports the connection of up to 64 escalators, and can host system configuration files through a web server. Users can view the status of the elevator in real time through a browser anywhere through Ethernet. The user-friendlyscreens multi-function monitoring screen system developed by it can display the operating mode of each escalator. The system also integrates remote control, scheduling operation, statistical playback information and other functions. However, the system currently only supports wired connections. The data cable of each elevator needs to be connected to the elevator workstation in the central control room through a switch to publish the elevator information to the Internet. The system wiring is very cumbersome, and it takes a lot of material and manpower to install. In addition, data distortion may occur due to long-distance transmission.

The escalator remote monitoring system AES of OTIS in the United States mainly focuses on the intuitive display of the escalator operation status and the transmission of fault signals. At the same time, it can record the operation status of elevators and escalators, centrally manage escalators, timely grasp the operation status of escalators, analyze the causes of escalator failures, and issue alarms in abnormal escalator conditions. However, the transmission of monitoring information can only be transmitted through a single link of the monitoring system itself, lacking redundancy, no audio and video transmission, and lacking remote control on-site functions. At the same time, it has certain limitations on the distance of the monitoring unit.

The ELINK 5.1 elevator/escalator monitoring system launched by KONE Elevator communicates through the LION network built into the device, and connects and communicates between devices in the group through a CAN line serial connection. Then the group devices transmit the data to the central control room through a CAN line or a network cable, and then the central control room sends it to the network. The system has the function of elevator and escalator operation traffic map, which can display the operation status of the elevator in a unique graphical way. Its pioneering elevator operation record return visit function can display a series of data such as the operation status, monitoring images, sound data, CPU fault code, etc. when the elevator fails in a return visit, so that maintenance personnel can analyze the cause of the failure.

The escalator Internet of Things monitoring system based on main control board data collection collects the elevator operating status through the data communication module in the elevator system itself. The collected data can be said to be very accurate and reliable, but this type of system is expensive and has complicated wiring. In addition, the replacement process will have a great impact on the normal operation of the escalators that have been put into use. It is not suitable for large-scale introduction into the current urban construction.
