Problems solved by technology

In the prior art, the glass measuring instrument mainly judges the reading of the lowest point of the meniscus and the scale line by the eyes during measurement, so it can only roughly calculate the volume of the liquid to be measured in the measuring cylinder, and the reading error is large, so it cannot be used with ordinary The measurement principle is verified
If the measurement method is used for the verification and calibration of glass measuring instruments, this measurement principle is simple and accurate, but it is not easy to automate

Embodiment Construction

[0027] The present invention will be described in more detail below in conjunction with the accompanying drawings.

[0028] figure 1 The cross laser measurement system 1 includes a glass gauge 11 , a cross laser 12 and a screen 13 located on both sides of the glass gauge, and a camera 14 . The camera 14 is aimed at the screen for collecting images on the screen 13, and the camera 14 is connected with the data processing system, and transmits the collected images to the data processing system for processing. Combine below figure 1 Explain the principle of the cross laser measurement system 1 to measure the liquid level: the cross laser 12 emits a red cross laser line with a wavelength of 650nm. After the laser line passes through the glass measuring device 11, it is projected on the screen, and the center of the cross is the reference point. When the laser line shoots to the liquid surface in the glass measuring vessel, due to the existence of refraction phenomenon, this part...

Abstract

The invention discloses a system and method for measuring the volume of a glass measuring vessel. The system is used for measuring the volume of liquid in the measuring vessel, including a cross laser measuring system for measuring liquid level height, a cross laser measuring system for measuring the accuracy Standard glass measuring system, standard metal measuring system for outputting fixed volume liquid, working platform for installing cross laser measuring system, and data processing system for processing liquid volume and liquid level height, and establishing volume table; based on The volume meter established by the data processing system and the accuracy measured by the standard glass gauge system are combined with the liquid level height measured by the cross laser measurement system to obtain high-precision volume parameters. The invention realizes the automatic reading of signals such as liquid level, capacity and temperature and the real-time processing of data. Compared with the traditional measurement method, the invention solves the technical bottleneck of human error in conventional measurement and greatly improves the measurement accuracy.

Description

technical field [0001] The invention relates to the field of volume measurement of glass gauges, in particular to a system and method for volume measurement of glass gauges. technical background [0002] The glass measuring device is a measuring device for measuring the volume of a liquid. It is widely used in the fields of chemistry, physics, biology, geology, medicine and metrology. It has a non-negligible position in the field of small-volume measurement. It is necessary to carry out metrological verification and calibration in accordance with the national verification regulations. The verification and calibration of glass gauges may seem simple, but in fact it is a very complicated task. At present, the verification and calibration methods of glass measuring instruments are mainly the measurement method and the volume comparison method, and most of the domestic verification departments adopt manual measurement methods, which makes the verification personnel heavy worklo...
