Automatic scanning measurement device and method for volume of oil tank

Abstract

The invention discloses an automatic scanning and measuring device for the volume of an oil tank. The system comprises a detection part, a control part and a data processing part, wherein the detection part is positioned in an oil tank to be detected and used for scanning the inner surface of an oil tank so as to measure the distance and the relative angle between the detection part and each pointon the inner surface of the oil tank; the detection part comprises a distance measuring sensor and a two-dimensional turntable; the distance measuring sensor is fixed on the two-dimensional turntable; the two-dimensional turntable is used for adjusting the orientation of the distance measuring sensor; the control part is connected with the detection part in a communication manner and used for sending a detection instruction to the detection part and collecting detection data from the detection part; the detection data comprises the distance measured by the distance measuring sensor and the orientation data of the distance measuring sensor; the control part is in communication connection with the data processing part and used for sending the detection data to the data processing part; andthe data processing part is used for calculating the volume of the oil tank to be detected according to the received detection data.

Description

technical field [0001] The invention relates to the field of metering and measuring instruments, in particular to an automatic scanning and measuring device and method for the volume of an oil tank. Background technique [0002] The effective application of high-precision and fast oil tank volume measurement technology in the measurement of large oil tanks and the storage of crude oil can greatly improve storage capacity and reduce waste. Large oil tanks mainly include vertical tanks, horizontal tanks and spherical tanks. How to measure accurately The volume of these large oil storage tanks is of great significance. However, due to the large volume and smooth surface of the oil tank, the measurement is very difficult, and the measurement accuracy and efficiency are low. [0003] There are many shortcomings in the existing oil tank volume measurement methods. For example, the geometric measurement method is usually based on the premise of regular oil tank shape and no deform...

However, due to the large volume and smooth surface of the oil tank, the measurement is very difficult, and the measurement accuracy and efficiency are low

[0003] There are many shortcomings in the existing oil tank volume measurement methods. For example, the geometric measurement method is usually based on the premise of regular oil tank shape and no deformation. It is usually calculated as a cylinder. Due to the irregularity of the oil tank and the large pressure during oil storage Deformation caused the measurement method to have obvious measurement errors; although the total station method has high measurement accuracy, it can only use limited discrete points to fit the surface of the oil tank, so there is a fitting error and it is difficult to reflect the real oil tank Surface: Ordinary scanner measurement method usually has low accuracy of the instrument itself, the accuracy of the instrument is difficult to meet the measurement requirements, and the degree of intelligence of the measurement is not enough, and it is impossible to combine the two measurement modes of non-cooperative target and with cooperative target for the measured object
