Embodiment Construction

[0062] The present invention uses radio frequency technology for real-time positioning and tracking of moving targets, uses high-precision infrared thermal energy detection technology for pre-alarming of the safety distance between people and vehicles, and uses high-sensitivity infrared access control technology for pre-alarming of the safety status of working wells. Blind area video monitoring technology monitors the blind area of ​​the door crane driving, and transmits the pre-alarm radio frequency signal to the door crane vehicle alarm device synchronously, so that the door crane driver can make a safe operation in time, and the pre-alarm information is sent to the vehicle alarm and analysis device analyzed and stored in.

[0063] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0064] Such as figure 1 The installation process and standards of a real-time monitoring and early warning system for ...

Abstract

The invention discloses a real-time monitoring and pre-warning system for security risks of gantry crane operation of a metro shield tunnel and a working method of the system. The system mainly comprises a gantry crane operation positioning reader, a positioning label device, a ground hoisting region infrared detection device, a working well hoisting region infrared access control device and a vehicle-mounted warning device. According to the system and the method, the real-time monitoring and pre-warning of a ground gantry crane of the metro shield tunnel as well as a moving target in a working well are effectively realized, and reliable guarantees are provided for the vertical transportation security risks in a construction process of the metro shield tunnel.

Description

technical field [0001] The invention belongs to the field of shield tunnel construction, and in particular relates to a real-time monitoring and early warning system for the safety risk of subway shield tunnel door crane operation and a working method thereof. Background technique [0002] In recent years, my country's subway construction has developed vigorously, and many cities have started or continued to carry out subway construction. In subway construction, the construction methods that are often used include open-cut method, shallow-buried underground mining method and shield method. The shield tunneling method is widely used because of its fast construction speed, high safety and little disturbance to the ground. [0003] One of the key procedures in the subway shield construction is the vertical transportation operation of the tunnel working well, and it is also one of the most frequently operated and heavy-duty construction links in the subway shield construction m...
