An intelligent early warning system for subway tunnels

Abstract

The invention relates to an intelligent early warning system for a subway tunnel, comprising a processing terminal, an image processing subsystem, an article inspection subsystem, a security inspection transmission device and a metal detection device; a security inspection channel is formed on one side of the security inspection transmission device, and the security inspection From the entrance to the exit, the passage is divided into a backpack placement area, a carry scanning area, and an item retrieval area; the security inspection transmission device includes a security inspection transmission device, and the security inspection transmission device includes an automatic transmission track, an X-ray detection structure, and a switching mechanism. , the image processing subsystem includes a backpack placement detection group, a carried object scanning image detection group, and an item retrieval image detection group; it is realized through intelligent detection of three steps of backpack placement, carried object inspection, abnormal item verification and backpack retrieval. The replacement of manual work and intelligent detection can reduce manual errors and avoid congestion.

Description

technical field [0001] The invention relates to a subway tunnel safety system, and more particularly, to an intelligent early warning system for a subway tunnel. Background technique [0002] The subway is a fast, large-capacity, electric-powered rail transit built in the city. Trains run on fully enclosed lines, and lines located in central urban areas are basically located in underground tunnels. Compared with other means of transportation in the city, the subway has many advantages in addition to avoiding urban ground congestion and making full use of space. 1. Large volume. The transportation capacity of the subway is 7 to 10 times larger than that of the ground bus, which is unmatched by any urban transportation. 2. On time, the punctuality rate is generally higher than the bus. 3. The speed is fast. The subway trains travel swiftly in the underground tunnel. The maximum speed is generally 80 kilometers per hour, which can exceed 100 kilometers and even reach 120 kil...

Problems solved by technology

And there are some disadvantages, and the disadvantages are more obvious. One is the high construction cost: the subway project has a long route and a wide range of influence. Usually, measures such as demolition, reconstruction, and protection of buildings, pipelines, and roads along the route are required. Costs other than the project bigger

Most of the subway projects are underground. Due to the need to drill the ground, the construction cost of the underground is higher than that of the ground

However, if there is an explosion in the subway tunnel, there may be a very serious danger, so the combustibles and combustibles are strictly controlled through security inspections. However, at least two security inspectors are still required for each subway station passage, and one inspects whether there is any liquid brought in. , one person needs to guide and maintain the order of the security check, and the cost of personnel is relatively high
