An anti-collision system based on the Internet of Things

Abstract

The invention discloses an anti-collision system based on the Internet of Things. Several positioning base stations and positioning tags are arranged in the pipe gallery. The positioning tags include a UWB ranging module connected to a control module, and the positioning base station includes a UWB measuring module connected to a signal processing module. The distance module uses UWB communication between the positioning base station and the positioning tag to obtain positioning data; the signal processing module takes any positioning tag as the center, and feeds back the positioning data of other positioning tags within a certain range to the control module of the positioning tag. It fully considers the impact of high temperature, high humidity, high signal interference and poor visibility working environment on the signal detection of sensor tag nodes in the power construction pipe gallery. It has accurate positioning, low energy consumption, good overall monitoring effect, and multi-layer early warning mechanism The synergistic effect effectively reduces the risk of mutual collision and improves the safety of operation, which has important engineering significance and promotion and application value.

Description

technical field [0001] The invention relates to an anti-collision system, in particular to an anti-collision system based on the Internet of Things, and belongs to the field of construction of electric utility tunnels. Background technique [0002] With the rapid development of my country's economy and the rapid increase of urban population, in order to solve the pressure on the environment caused by population flow and relative concentration of employment points, and to meet the needs of national environmental changes, it has become an inevitable trend to carry out various underground projects. [0003] With its unique advantages, the tunnel gallery as an engineering building of an underground passage shows an obvious growth trend. In power transmission operations, there are often requirements for the wiring of tunnels such as rivers, lake bottoms, and mountains. [0004] Tunnel pipe gallery projects mostly exist in difficult and complex environments, and are easily affect...

AI Technical Summary

Problems solved by technology

[0008] At present, the outdoor GPS positioning technology is very mature, but it is not suitable for the operation in the pipeline corridor with complex environmental problems such as high-intensity signal interference and attenuation; traditional vehicle early warning radar often uses laser and camera video radar to reduce the risk of collision. The reason is that the detection distance is short, and there are problems such as dust and low visibility in the tunnel, so the early warning effect is poor; at the same time, the vehicle in the tunnel uses a horn to remind the surrounding vehicles and personnel of the anti-collision method, which is inefficient and single, and the vehicles and personnel cannot know in time The relative distance and speed from other vehicles makes it difficult to react in time and take emergency evasion measures

[0009] To sum up, there are serious defects in the safety of construction and transportation operations in utility corridors such as electric power transportation
