Problems solved by technology

[0002] Traditional slope and building structure safety monitoring uses inclinometers, static levels, mechanical displacement meters or piezoelectric acceleration sensors. The functions of each instrument are single. For example, the inclinometer can only measure the inclination, and the static level can only measure the settlement. Displacement gauges can only measure displacement, acceleration can only measure vibration
In addition, the commonly used inclinometer is single-axis measurement; the static level requires at least two terminals to work together to measure, and the sensing range is limited, not only the product cost is high, but also the installation and maintenance are high; the mechanical displacement meter can only measure Displacement within the measurement range of the body and in the installation direction; when the piezoelectric acceleration sensor is stationary, it cannot measure the zero point, and the frequency range is small, which leads to insufficient freedom of product use and certain limitations
[0003] In addition, regarding the summary of data, the monitoring data collected by multiple sensors with a single function are exchanged in a variety of different ways and sent to the local or remote software platform. Different programs have different data transmission delays, resulting in time reference points This kind of asynchronous data cannot be truly synchronized to the 3D simulation platform (digital twin) to reflect the dynamic changes of the real physical structure in real time

Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0034] The invention provides a multi-degree-of-freedom micro-vibration diagnosis method and a sensing terminal, which solves the problems of low data reliability, installation of multiple single-function sensors, complex installation, high construction cost, inconvenient data communication, and data synchronization in the prior art. Low performance, poor timeliness, unable to give dynamic simulation on the software platform, and give a preliminary diagnosis and other deficiencies.

[0035] The multi-degree-of-freedom micro-vibration diagnosis method of the present invention, such as figure 1 As shown, the steps are as follows:

[0036] Step 1), the acceleration sensor is used to determine whether there is vibration or disturbance (usually micro-vibration) at the observation point, and if so, the acceleration sensor performs data collection u...

Abstract

The invention relates to a multi-degree-of-freedom micro-vibration diagnosis method and sensing terminal. Calculation and observation of settlement and displacement values are realized, and credibility analysis is carried out on the settlement and displacement values obtained by calculating data samples acquired at each acquisition time point, thereby improving the accuracy of an observation result. Through vibration detection and trigger data acquisition including acceleration data, magnetic field data, angle data, positioning data and the like, the sensors are high in collaboration, the datarelevance at the same time is high, and the dynamic change condition of an observation point can be reflected in real time. According to the invention, non-contact sensing, edge calculation, data storage, backup power supply, communication transmission, encryption chips and the like are realized, a wider acquisition frequency can be freely selected, and micro-vibration and magnetic force change can be freely sensed; and the method and the sensing terminal can be applied to different application scenes such as dangerous buildings, ancient buildings, bridges, underground pipe galleries, dams, tunnels and iron towers, and provide powerful support for disaster monitoring and early warning and forecasting in China.
