Intelligent terminal for remote real-time monitoring on elevator running

Abstract

The invention discloses an intelligent terminal for remote real-time monitoring on elevator running. The intelligent terminal comprises a processor module, a digital signal quantity acquisition module, an analog signal quantity acquisition module, an internal mass memory and a GPRS data transmission module; the digital signal quantity acquisition module, the analog signal quantity acquisition module, the internal mass memory and the GPRS data transmission module are electrically connected with the processor module. The intelligent terminal acquires elevator real-time running states comprising all switching values and tractor states, temporarily stores data when the intelligent terminal is not connected to the internet, and transmits the data to a server through a GPRS network when the intelligent terminal is connected to the internet. The intelligent terminal is easy and convenient to install and low in installation cost, acquires comprehensive elevator running data and wirelessly transmits the elevator running data to the server for analysis and storage, and powerful guarantee is provided for elevator trouble hunting and safety operation.

Description

technical field [0001] The invention relates to the technical field of elevator applications, in particular to an intelligent terminal for remote real-time monitoring of elevator operation. Background technique [0002] With the rapid development of China's elevator industry, China's elevator production, inventory and annual growth rate are currently the world's first. By the end of 2015, the total number of elevators in the country has exceeded 4 million. However, with the rapid development of the elevator industry in my country, problems related to elevator safety are becoming increasingly apparent. Elevator safety accidents occur frequently. In 2015 alone, there were 58 serious elevator accidents and 46 deaths, which seriously threatened personal safety. [0003] At the same time, huge elevator maintenance will also consume a lot of manpower, material resources, and financial resources. If the traditional method of regular inspections is still adopted, it is obviously not...

AI Technical Summary

Problems solved by technology

[0004] There are many deficiencies in the existing elevator running state acquisition equipment: generally, the existing sensors of the original elevator are used to collect signals through wiring connections with sensors installed in elevator cars, hoistways, machine rooms, pits, etc., and the connections are scattered. Complex, high cost of materials and installation, and high installation man-hours; Generally, only some elevator limit switches, position switches, and working status switches are collected, but the working status of the traction machine, which is an important running part of the elevator, is not monitored; generally After collecting the elevator running status data, it can be connected through the communication cable, and the data can be uploaded to the server device locally, but it cannot be transmitted remotely due to the communication distance limitation of the cable and interface type.
