Remotely-controlled monitoring device of elevator

Abstract

The invention discloses a remotely-controlled monitoring device of an elevator. The device comprises an elevator data processing module, a mobile communication module and an in car voice and signal module, wherein the elevator data processing module bi-directionally exchanges elevator data with an elevator control system; the in car voice and signal module bi-directionally exchanges elevator car voice and alarm signals with an elevator alarm and conversation system; the elevator data processing module bi-directionally exchanges data or voice with the in car voice and signal module through the mobile communication module and a remote control center. The device is based on a mobile communication network and has functions of remote control and remote conversation, and a remote video supervision function can be realized in the third generation (3G) mobile communication network or the network with higher bandwidth.

Description

technical field [0001] The invention relates to an elevator monitoring device, in particular to a nationwide elevator remote monitoring device. Background technique [0002] With the rapid development of our country's social economy, the real estate industry is showing a great development situation. As a means of transportation in buildings, elevators have been more widely used. As special equipment, the safety and reliability of the elevator is very important, and the elevator monitoring device was invented to ensure the safe and reliable operation of the elevator. [0003] At present, the elevator monitoring devices are mainly divided into the following types: [0004] 1. Fieldbus-based monitoring device, one device monitors one elevator controller, and a group of monitoring devices are connected to the Internet through the field bus. The advantage of this method is low cost, and the disadvantage is that wiring is inconvenient and the monitoring range is limited. [0005...

AI Technical Summary

Problems solved by technology

Although this method solves the problem of inconvenient wiring and expansion, it also brings reliability problems

Because both the above-mentioned RF module and the Zigbee interface module use public radio frequency, the transmission power is strictly limited. If the building is blocked, other equipment interferes or the communication distance is slightly longer, the reliability will be problematic.

And in order to extend the communication distance, the signal must be relayed through multiple radio frequency modules. Once the intermediate node fails, the entire communication network will be destroyed, so this is not a good networking method

[0006] 3. A remote monitoring device through a telephone line or a network cable, such as the Chinese invention patent specification CN100385472C (the patent number is ZL200510050699.3, and the authorization announcement date is April 30, 2008). Or telephone lines, using embedded systems to access the Internet for data communication, this system has defects such as high cost (high equipment investment costs, high operating costs), complex configuration, and frequent disconnections

If the Internet cable and telephone line are not reserved in the building, remote monitoring cannot be realized

[0007] The latest elevator monitoring device of the invention is a remote monitoring device based on GPRS (General Packet Radio Service). Elevator Remote Monitoring and Early Warning System", but the monitoring device is connected one-to-one with the elevator, and the equipment investment cost is relatively high

The "Elevator Wireless Remote Monitoring System" disclosed in the Chinese Invention Patent Application Publication Specification CN1887674A has no remote communication function and cannot meet the requirements of the new national standard "Elevator Remote Alarm System"

[0008] The elevator data field acquisition device described in Chinese invention patent CN101374357B (patent number ZL200710147506.5, authorized announcement date on December 29, 2010) needs to install various sensors that do not belong to the elevator control system on the car top and machine room. There is no operational feasibility in the project, and the reliability risk is relatively large
