Fire building detection warning system and method based on laser overall meters

Abstract

The invention discloses a fire building detection warning system based on laser overall meters. The system comprises two or more overall meters with standard serial ports, a communication auxiliary unit which is connected with the standard serial ports of all the overall meters one to one, a communication main unit which conducts wireless communication with the communication auxiliary unit, and adata monitoring platform connected with the communication main unit. The invention further discloses a detection warning method of the fire building detection warning system. Multiple overall meter devices are adopted for omnidirectionally monitoring buildings in a fire scene, each overall meter is configured with the communication auxiliary unit so that real-time intercommunication of monitoringdata can be achieved, the communication main unit uniformly receives the monitoring data of all the overall meters and conducts fire building deformation warning through the data monitoring platform,the real-time performance of fire building deformation monitoring is greatly improved, and a reliable guarantee is provided for life safety of fire fighters.

Description

technical field [0001] The invention relates to the technical field of fire safety, in particular to a fire building detection and early warning system based on a laser total station and a detection and early warning method thereof. Background technique [0002] Fire is generally an accident caused by people's improper use of fire. Once a fire accident occurs, people try their best to reduce the loss of life and property caused by it, and fire rescue also occurs. When a fire breaks out in a building, the smoke generated by the fire, the high temperature and the burning of the building components will damage the building structure and cause the building to deform to a certain extent. When the deformation reaches a certain level, the building will collapse, which will seriously threaten The life safety of fire rescue personnel in the fire scene. Therefore, how to detect the structural deformation of the building in advance in a fire is very important, which is equivalent to p...

Problems solved by technology

However, when the total station is used in the monitoring of building deformation in fire, since the total station belongs to single-point measurement, a single total station has a single measurement parameter for building deformation, which cannot fully reflect the actual deformation of the building in the fire. Multiple total stations are used for multi-directional auxiliary measurement. In this case, multiple monitoring personnel are required to take readings at each total station position, and the conversion between measurement data and deformation data requires manual calculation, which consumes human resources. At the same time, due to the high real-time requirements for building deformation monitoring in fire scenes (different from the conventional total station measurement, the surveyors can gather together to summarize the measurement data after a certain period of time), and there are differences between monitoring personnel at different locations. The great inconvenience of real-time communication makes it difficult for the current total station to have further application in the monitoring of fire building deformation
