Intelligent building inclination detecting and early-warning device and detecting method

Abstract

The invention discloses an intelligent building inclination detecting and early-warning device and a detecting method. The device comprises a laser emitter, a laser receiver, a horizontal alignment laser ball, a horizontal alignment laser target, a stepping motor, a circuit board, a GSM antenna, a support and a shell. The distance between the device and a building can be measured through the time difference and light velocity of emitting and receiving of lasers, and the included angle between the building and the horizontal plane can be obtained according to the triangle cosine theorem and the sine theorem. The horizontal alignment laser ball emits horizontal lasers all the time, the horizontal alignment laser target rotates along with the shell, and the horizontal alignment laser ball and the horizontal alignment laser target are used for aligning the shell to be horizontal. The stepping motor is used for precisely controlling the rotation angle of the shell. When the measured included angle between the building and the horizontal plane is close to a danger value, early-warning signals are sent to a background through the GSM antenna. No auxiliary devices need to be arranged on the building, data is directly transmitted to the background through a GSM network, and a great promotion effect is achieved for the whole building industry and work of the supervision department.

Description

technical field [0001] The invention relates to the field of construction equipment safety monitoring, in particular to an intelligent building tilt detection and early warning device and detection method. Background technique [0002] The reasons for the tilting phenomenon of buildings can be divided into external reasons and human reasons: [0003] External reasons include geological disasters, meteorological disasters, etc., such as earthquakes, volcanoes, ground subsidence and other geological disasters. The movement or rupture of the earth's plates will destroy the original foundation structure of the building, causing the building to tilt or even collapse; Debris flows, landslides, ground subsidence caused by mining resources, unreasonable building design, and use of substandard materials during construction will all cause buildings to tilt. [0004] In recent years, there have been a lot of news about accidents caused by building inclinations. There are regulations a...

If it causes obstruction or loss to the adjacent party, the infringement shall be stopped, the obstruction shall be eliminated, and the loss shall be compensated” and the “Property Law” states that “the construction of a building shall not violate the relevant national engineering construction standards, and hinder the ventilation, lighting and sunlight of adjacent buildings”, etc. The most serious consequence is that the tilt of the house has endangered or damaged the safety of people's lives and property, which will seriously affect the stable development of society

[0005] In order to prevent the occurrence of hazards caused by building tilting, many research and development institutions have developed equipment or systems such as building tilt monitoring, which have a certain effect on building deformation monitoring. However, the current building tilt monitoring equipment is designed according to traditional ideas. Installing sensors in key locations of the building or using bulky mechanical measuring instruments to detect building tilt data is very costly, and the latter is extremely inconvenient to use

[0006] The essence of all measurement tools is to use mathematical principles, but there are very few designs that can use higher-level mathematical knowledge to cleverly solve practical problems
