Construction lift monitoring device based on camera and monitoring method

Abstract

The invention relates to a construction lift monitoring device based on a camera and a monitoring method. The monitoring device is connected with a supervision center through a communication network. The monitoring device comprises a host, an IC card, the camera and a power module, wherein the host comprises a main control plate and a people counting plate which are connected mutually; the power module is connected with the main control plate and the people counting plate; the people counting plate is connected with the camera; and the IC card is connected with the main control plate. The camera collects internal videos of a lift and transmits the internal videos to the people counting plate; the people counting plate analyzes the video signals to obtain information of the number of people in the lift and sends the information of the number of the people to the main control plate; and the main control plate judges whether the number of people surpasses a preset threshold value, and carries out alarming and locks the lift if the number of people surpasses the preset threshold value. Compared with the prior art, the construction lift monitoring device has the advantages of being easy to install, low in cost, high in precision, and high in safety and the like.

Description

technical field [0001] The invention relates to the technical field of safety detection and control, in particular to a camera-based construction hoist monitoring device and monitoring method. Background technique [0002] With the continuous development of my country's national economy, the number of high-rise buildings has gradually increased, and the number of construction elevators for building high-rise buildings has increased sharply. In addition to being used in high-rise buildings, construction elevators can also be used in the construction of bridges, large-scale chemical plant cooling towers, and power plants. For various construction occasions such as chimneys, radio and television towers, and coal mines, construction hoists have become an indispensable mechanical equipment in the construction industry. [0003] As a construction elevator that undertakes the dual transportation tasks of vertically transporting building materials and personnel, its safety performanc...

AI Technical Summary

Problems solved by technology

[0004] 1. Focus on elevator operating parameters and environmental monitoring, lack of combination with safety supervision methods;

[0005] 2. Use binocular cameras to identify the number of people in the ladder cage, which is costly;

[0006] 3. Since the installation height of the binocular camera is limited by the height of the ladder cage, it is difficult to install, and there are many blind spots in video statistics, resulting in poor accuracy of people counting;

[0007] 4. People counting and video surveillance are disconnected, there is no integration, usually only video surveillance or people counting;

[0008] 5. The position and time of the elevator were not accurately measured;

[0009] 6. Failure to manage the driving of construction elevators;

[0010] 7. Lack of voice prompts;

[0011] 8. The power supply problem of the construction elevator is not considered, and some safety devices cannot be used directly in the elevator, and the practicability is poor;

[0012] 9. The monitoring system is basically closed and lacks scalability
