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...

Embodiment Construction

[0046] Below, the present invention is described in detail with reference to accompanying drawing and embodiment:

[0047] like Figure 1~2 As shown, a construction operation safety protection and early warning system based on real-time positioning includes a positioning tag 1 with a relay and a positioning tag 2 at the construction site, and the positioning tag 1 with a relay will be connected with the No. 4. The distance between the No. III base station 5 is sent to the communication base station 6, and the positioning tag 2 sends the distance between the No. I base station 3, the No. II base station 4, and the No. III base station 5 to the communication base station 6. The communication The base station 6 communicates with the comprehensive management display terminal 8 and the positioning engine server 9 and sends distance information.

[0048] Both the positioning tag 1 and the positioning tag 2 with relays are UWB tags.

[0049] Between the positioning tag 1 with a rel...
