Description

Technical Field

[0001] The present invention relates to the technical field of engineering monitoring, and in particular to a deflection monitoring device and a monitoring method for an existing building cover plate. Background Art

[0002] With the acceleration of urbanization, urban land resources are becoming increasingly scarce. Rail transit, as an important part of urban transportation, occupies a large area. In order to improve land utilization, the superstructure building model came into being, which organically integrates urban rail transit with urban land planning, and improves the commercial value of land by building superstructure buildings above rail transit facilities such as subway parking lots. However, this model also brings new challenges, namely how to minimize the impact on the safety of existing building structures during the construction of superstructure buildings. Therefore, the deflection monitoring technology of existing building covers has become an important research direction in the field of engineering monitoring. From the initial simple visual inspection to the later mechanical measurement, and then to modern electronic and optical measurement technology, the deflection monitoring technology of existing building covers has undergone considerable development.

[0003] At present, the deflection monitoring technologies of existing building cover plates mainly include laser rangefinders, intelligent sensors and GPS deformation and displacement monitoring equipment. These technologies can monitor the deflection of building cover plates to a certain extent. Laser rangefinders and intelligent sensors are widely used because of their relatively low price and simple operation, but their monitoring range is limited. Usually, they can only monitor the deployed measurement points and cannot fully cover the entire building cover plate. Although GPS deformation and displacement monitoring equipment can provide continuous monitoring data, its data error sources are many, and it cannot achieve all-weather automatic monitoring. At the same time, its performance is limited under severe weather conditions and cannot meet the monitoring needs of high precision and high reliability.

[0004] Although the existing monitoring technology can meet the monitoring needs to a certain extent, there are still some obvious shortcomings. First, the existing technology has limitations in monitoring accuracy and error control, especially in complex environments, such as subways, high-speed railways and other facilities that are prone to vibration. The monitoring errors of these technologies are large and cannot meet the requirements of high-precision monitoring. Secondly, the existing technology is insufficient in all-weather automatic monitoring. Especially in severe weather conditions such as rain, snow, fog, etc., the accuracy and stability of the monitoring equipment will be affected. In addition, the existing technology also has limitations in adapting to different monitoring environments, and it is impossible to flexibly adjust the monitoring direction and position to meet the needs of different building structures and environments. These shortcomings limit the application scope and effect of the existing building cover deflection monitoring technology. Summary of the invention

[0024] Based on the same technical concept, in a second aspect, the present invention proposes a method for monitoring the deflection of an existing building cover plate, using the device for monitoring the deflection of an existing building cover plate described in the first aspect;

[0025] The deflection monitoring method of the existing building cover plate comprises:

[0026] According to the actual survey results of the area where the building cover plate is located, a plurality of target monitoring positions distributed at intervals are determined on the building cover plate;

[0031] One or more technical solutions proposed in this application have at least the following technical effects:

[0032] 1) The technical solution of the present application is provided with a box, a monitoring mechanism and a control mechanism. When in use, a placement space is formed in the box, an operation window is formed on the box, and an opening is formed on the top of the box to connect the placement space with the outside world. At the same time, the monitoring mechanism and the mechanism are installed in the placement space, so that the rangefinder in the monitoring mechanism can be rotatably extended out of the box from the opening, and the angle adjustment component can drive the rangefinder to rotate around the opening to adjust the monitoring direction and monitoring position of the rangefinder.

The monitoring box is equipped with environmental monitoring equipment including a dust detection unit, a humidity detection unit, and a correction unit to monitor the dust concentration and humidity in the surrounding environment. When the dust concentration is too high, the control mechanism can be responded to in time to stop the measurement behavior of the monitoring mechanism. The dust detection unit can avoid the excessive dust concentration in the surrounding environment causing the monitoring mechanism to measure too large data. The humidity detection unit and the correction unit can detect the humidity of the surrounding environment and correct the dust concentration detection value to avoid the excessive humidity of the surrounding environment causing the dust detection unit detection value to be too large, causing the monitoring mechanism to terminate the measurement behavior prematurely, thereby realizing all-weather monitoring.

[0035] 4) The present invention monitors each point of the existing building cover plate through a monitoring mechanism, obtains initial data, i.e., the distance S from the measuring point to the monitoring mechanism, and the corresponding vertical rotation angle θ, and then performs data processing to obtain the deflection deformation value of each point of the existing building cover plate. The data monitored by the monitoring mechanism and the environmental monitoring equipment of the present invention are monitored by different devices respectively without interfering with each other.
