Description

technical field [0001] The invention relates to a box-type inclinometer capable of automatic collection and data storage, which can not only realize online real-time collection, but also a module that can automatically collect and store data at regular intervals, and relates to the field of safety monitoring industries such as structures. Background technique [0002] At present, in the fields of structure and building displacement monitoring, the horizontal displacement change is an important monitoring object, and the horizontal displacement can be measured by GPS, total station, displacement sensor, inclinometer and other methods. The basic measurement principle of the inclinometer is: through the change of the inclination angle, calculate the horizontal displacement W=H*Sin(α) through the relationship of the trigonometric function, where H is the installation height of the box-type inclinometer, and α is the inclination angle. [0003] In order to make the monitoring sys...

AI Technical Summary

Problems solved by technology

[0005] First of all, the method of manual monitoring of horizontal displacement cannot achieve real-time and all-weather data collection, and the equipment used is complicated to operate and has high maintenance costs

[0006] Secondly, traditional monitors cannot save data and record time. During a single acquisition, only one frame of data is returned by the serial bus. When failures such as serial bus communication fail, the data frame will be lost and the data cannot be traced.

Moreover, the traditional displacement monitor needs computer control to collect. When the number of monitoring objects is relatively large, there will be a problem of occupying system resources.

[0007] To sum up, the traditional displacement monitor or manual monitoring has a single function, cannot collect real-time autonomously, cannot automatically store data, and is difficult to meet the requirements of the current working conditions
