Problems solved by technology

The disadvantages are that first, the monitoring data of only one inclination sensor is used to represent the deformation of a span of 1m, and there is a certain subjective error; second, the whole equipment is complicated and heavy, which is not conducive to mobile use or fixed installation, and the volume and The quality and complexity of cables limit the number of inclinometer deployments, which not only reduces the continuity of deep monitoring, but also exacerbates the difficulty of equipment deployment and replacement maintenance

Embodiment approach

[0047] The present invention also provides an implementation method of a fixed intelligent inclinometer system, including the following two methods:

[0048] Method 1. For the inclination monitoring of engineering structures, first determine the monitoring layout points according to the construction plan, and fix the intelligent inclinometer in the steel mesh (cage) before the structure is poured. The acquisition base station sends activation instructions, and then sends radio frequency signals to each inclinometer through the data acquisition base station, so as to realize the purpose of activating the intelligent inclinometer through remote commands; in this engineering background, the inclinometer can be used individually and flexibly without measurement Cumulative deformation over longer distances;

[0049] Method 2. For monitoring the horizontal displacement and deformation of the underground space, first, the inclinometer is laid out based on the geological exploration d...

Description

technical field [0001] The invention belongs to the field of engineering safety monitoring, and in particular relates to a fixed intelligent inclinometer, a system and an implementation method. Background technique [0002] With the further deepening of modernization, my country is gradually increasing its efforts in basic engineering construction, including a large number of infrastructure such as traffic engineering, water conservancy and hydropower engineering, and mine engineering. During the construction of these projects, it is inevitable to transform and utilize the underground space, such as the excavation of tunnels, foundation pits, and mountain slopes. Therefore, in order to ensure the smooth development of the construction process and ensure the safety of the lives and property of the personnel on site, it is necessary to carry out necessary stability and safety monitoring of the engineering structure and geological rock soil environment involved in the undergrou...
