Construction safety protection early-warning system and method based on real-time positioning

Abstract

The invention discloses a construction safety protection early-warning system and method based on real-time positioning, and the system comprises a positioning tag with a relay and a positioning tag at a construction site. The positioning tag with the relay transmits the distances between the positioning tag with the relay and base stations I, II and III to a communication base station. The positioning tag transmits the distances between the positioning tag and the base stations I, II and III to the communication base station. The communication base station communicates with a comprehensive management display terminal and a positioning engine server, and transmits the distance information. The early-warning method comprises the following steps: obtaining the space coordinate position and acorresponding time value, calculating the distances between devices in a construction operation region, and judging whether the distances exceed an early-warning threshold value or not, and giving asound and light alarm. The system and method are strong in anti-interference capability, reduces the safety management risk, and improves the safety management level and comprehensive benefits of building construction. The system and method facilitate the wide popularization and application for building construction enterprises.

Description

technical field [0001] The invention belongs to the technical field, and in particular relates to a construction operation safety protection early warning system based on real-time positioning and an early warning method thereof. Background technique [0002] Civil construction sites generally require a lot of welding operations. Acetylene and oxygen are used for metal welding, cutting, metal surface spraying, etc. The chemical properties of acetylene are active, which belongs to the Class A fire hazard category, and has a greater fire and explosion hazard. Fire and explosion protection is very important; if the oxygen cylinder and acetylene cylinder are too close, there will be great safety hazards; if the oxygen cylinder and acetylene cylinder are too close to the welding torch in the working state, there is also the possibility of explosion or fire. Therefore, two types of problems need to be solved. One is that if the distance between the oxygen cylinder and the acetylen...

Problems solved by technology

[0002] Civil construction sites generally require a lot of welding operations. Acetylene and oxygen are used for metal welding, cutting, metal surface spraying, etc. The chemical properties of acetylene are active, which belongs to the Class A fire hazard category, and has a greater fire and explosion hazard. Fire and explosion protection is very important; if the distance between the oxygen cylinder and the acetylene cylinder is too close, there will be a great safety hazard; if the distance between the oxygen cylinder and the acetylene cylinder is too close to the welding torch in the working state, there is also the possibility of explosion or fire

Therefore, two types of problems need to be solved. One is that if the distance between the oxygen cylinder and the acetylene cylinder is within the limit of 5m, an early warning should be provided so that the on-site security personnel can locate and take measures in time to avoid potential safety hazards; When the distance between the welding torch and the second-class bottle is within the limit of 10m, an early warning should also be provided so that the operator can adjust the working distance in time

The traditional method is to separate the two types of bottles in two types of work vehicles or store them in different yards, but this cannot solve the problem well

[0003] In addition, in civil engineering operations, such as the butt joint assembly of immersed tube tunnels, the butt joint of steel cages on underground diaphragm walls, the equipment units in the welding work site must meet the safety requirements of the work, and the workers in dangerous work areas such as tunnels during construction need to be located and tracked. Personnel need instant reminders and warnings, and traditional technical means cannot effectively solve the requirement of real-time positioning and early warning
