Unmanned remote maintenance system for elevator

Abstract

The invention relates to the technical field of elevators, in particular to an unmanned remote maintenance system for an elevator. The unmanned remote maintenance system comprises a monitoring deviceand an alarm device. The monitoring device comprises an elevator monitoring host and sensors electrically connected to the elevator monitoring host, and the sensors comprise an acceleration sensor, aspeed sensor, an infrared sensor, at least two cameras, a tension sensor installed on a lift car traction cable, a power sensor and a backup power source which are installed on elevator power lines, and a wind speed sensor and a wind direction sensor which are installed at the top or the bottom of the lift car, wherein the acceleration sensor, the speed sensor, the infrared sensor, and the at least two cameras are installed in a lift car. The alarm device is provided with an alarm host, and the elevator monitoring host is electrically connected with the alarm host. A sliding device is arrangedat the top in the lift car, and the sliding device is provided with at least one of the cameras. The unmanned remote maintenance system for the elevator is scientific in structure, detection structures of the various sensors of the monitoring device are adopted, and the elevator can be maintained remotely by using a computer to find an abnormal state during operation.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an unmanned remote maintenance system for elevators. Background technique [0002] Elevator is a kind of transportation equipment serving buildings, especially the specific carrier of high-rise buildings. Its car moves on a rigid track perpendicular to the horizontal plane or with an inclination angle of less than 1° from the plumb line. The size of the car is proportional to the building, so as to facilitate the entry and exit of passengers or the purpose of loading and unloading goods. As a special means of transportation in buildings vertical or parallel, or at an angle of 45°, elevators can be divided into low-speed elevators (less than 4 m / s), fast elevators (4 to 12 m / s) and high-speed elevators (12 m / s) according to speed. above), and escalators. Passenger elevator is an elevator designed for transporting passengers, including traction system, guidance system, car, doo...
