Image identification principle-based on-line monitoring and measuring method and sensor

Abstract

An image identification principle-based on-line monitoring and measuring method is disclosed. A quantity to be measured of an object to be measured can be obtained via adoption of a mechanical type measuring tool, the obtained quantity to be measured can be demonstrated as information which can be shot by an optical system and processed and identified by an image identification system; after a picture of the quantity to be measured is taken via the optical imaging system, the picture is deciphered via the image identification system into specific numerical values to be measured; at last the deciphered numerical values are displayed, recorded or transmitted to a data collecting system via a data uploading interface, and therefore on-line monitoring can be realized. A long service life design principle is adopted for the mechanical type measuring tool and mechanical structures relevant to the mechanical type measuring tool; a replaceability design principle is adopted for the optical imaging system, the image identification system, the data uploading interface and relevant electronic structures; an on-line type sensor which employs the method comprises a mechanical measuring core and an image information collecting and processing and electronic transmission system. The sensor has advantages of a conventional pure mechanical type measuring tool and an electronic measuring tool.

Description

technical field [0001] The invention belongs to the technical field of civil engineering measurement, and relates to an on-line monitoring and measuring method and a sensor based on the principle of image recognition. Background technique [0002] Monitoring and measurement in the field of civil engineering usually has the following characteristics: 1. The change value to be measured is small; 2. The change to be measured is slow; 3. The distance span is large and it is not easy to measure on-site. It is hoped that the measured value can be collected online; 4. The measurement time span Sometimes a measurement lasts for several years, decades or even hundreds of years; outdoor measurements are often required, and the measurement equipment will face harsh environments such as large temperature differences, wind and sun, rain, and dust. [0003] The measurement tools commonly used in the civil engineering field can be roughly divided into two categories. The first is a purely...

Problems solved by technology

However, because the performance of electronic components is susceptible to temperature interference, its ability to resist electromagnetic interference and temperature interference is weak; the life of general electronic components does not exceed 10 years, which makes it impossible to perform long-term online measurement; when replacing measurement tools, due to the new and old measurement tools The discrete nature of the characteristics often leads to the inability to connect the measurement data

[0006] Among the current measurement tools, purely mechanical measurement tools have high precision, high reliability, and small jitter, but the measurement results cannot be uploaded in real time; the life of electronic products usually does not exceed 10 years, and the measurement results are easily affected by temperature.

At present, there is no sensor in the field of civil engineering that can effectively meet the requirements of high measurement accuracy, small jitter, long life, strong anti-interference ability, and online collection.
