Neuron model displacement or deformation monitoring method of electric transducer embedded with microcomputer

Abstract

The invention relates to a displacement test method which is suitable for static and dynamic displacement measurement of a structure of scale in a long line range or a space range. The neuron model displacement or deformation monitoring method of an electric transducer embedded with a microcomputer is characterized in that a multi-point neuron structure model, the transducer as a neuron body and a supplement rigid rod as a neuron myelin are connected to form a neuron basic unit assembly; a number of neuron assemblies are connected in series to form a nerve chain; and a start node is used as a benchmark to acquire the relative displacement of each unit to determine the attached structure deformation. Compared with the prior art, the structure deformation and dynamic characteristic measuring method provided by the invention can overcome the limits of traditional mechanical temporary test and optical test method environment impacts and high cost price, and is especially suitable for large range or long scale and multi-point long-term monitoring, such as longitudinal and transverse deformation measurement and real-time monitoring of a building, a bridge, a tunnel, a dam, a slope and other structures.

Description

technical field [0001] The invention relates to a displacement test method, which is suitable for the static and dynamic displacement measurement of structures in the long-line range or space range, and is especially suitable for the longitudinal and lateral spatial deformation of structures such as buildings, bridges, tunnels, dams and slopes. Measurement and real-time monitoring. Background technique [0002] At present, there are many methods for measuring the displacement or deformation of structures, including displacement sensors, acceleration sensors, optical fibers, and even optical instruments such as infrared and laser. According to the classification principle, it can be divided into three categories: optical, electronic and mechanical. Among these test methods, the mechanical method is the traditional test method, which is not suitable for long-term measurement in the field. It is usually only suitable for short-term manual measurement, and the test accuracy is ...

Problems solved by technology

Among these test methods, the mechanical method is the traditional test method, which is not suitable for long-term measurement in the field. It is usually only suitable for short-term manual measurement, and the test accuracy is low; while the optical test method has high test accuracy, but it is affected by the environment such as light. The impact is obvious, and the installation and operation are complicated and expensive, which is usually only suitable for short-term measurement; while the electronic test method is currently a method that can be used for long-term and field measurement. Installed, sealed and replaced to improve its service life

[0003] Compared with the measurement and monitoring of long and large structures, especially structures that require long-term monitoring, the above three types of methods are used not only because of the large number of measuring points and high cost, but also because of the complex and difficult data processing in the later stage, and the influence of data errors between each measuring point. Large, and the data accuracy will be reduced due to the environment

If you want to test the dynamic characteristics of the structure such as mode shape or three-dimensional dynamic deformation, the above methods will be limited
