The utility model discloses a skid-mounted oil well intelligent metering system, and relates to the technical field of oil and gas conveying metering, the input end and the output end of a filter are respectively connected with an inductor, the inductors are connected with a PLC control cabinet, the PLC control cabinet compares the values of the inductors at the input end and the output end to judge whether the filter is blocked or not, and if the filter is blocked, the PLC control cabinet is connected with the PLC control cabinet. When the PLC control cabinet detects that input and output flow velocity values or pressure values do not change, it means that the filter is not blocked, and the detection value of the mass flow meter is normal data, and when the input and output values detected by the PLC control cabinet change, the detection value of the mass flow meter is wrong data, and the data is abandoned, the filter needs to be opened, and the filter is not blocked.

This invention discloses a method for automatic gyroscope drift compensation in a high-precision optical axis motion control device, belonging to the field of servo turntable control technology. This invention uses a three-axis fiber optic gyroscope mounted on the pitch axis to sense spatial angular velocity. Fiber optic gyroscopes eliminate errors caused by friction from rotating mechanical parts, resulting in high angular velocity measurement accuracy and a wide range of measurable angular velocities. The laser gyroscope used in this invention has a velocity measurement range of ±600° / s and a minimum sensitive angular velocity of less than ±0.001° / s. Fiber optic gyroscopes have a wide operating temperature range, from -50℃ to 60℃, requiring no heating, and exhibit short start-up time and fast system response. This invention proposes a method for automatic gyroscope drift compensation in a high-precision optical axis motion control device, employing a two-stage coarse-fine compensation method to achieve rapid compensation for fiber optic gyroscope drift. It first performs a coarse compensation, followed by up to five (the number of times is configurable) fine compensations. The algorithm is simple and efficient, with short compensation time, and does not consume significant CPU resources for complex calculations, thus improving optical axis stability.

This invention discloses an automatic component leveling system, application, and method based on a distance measuring device. It solves the problem in existing technologies where leveling side beams requires workers to use levels or similar instruments for measurement, resulting in low measurement accuracy. The system offers the advantages of high accuracy and high efficiency. The specific solution is as follows: An automatic component leveling system based on a distance measuring device includes a worktable supporting multiple drive mechanisms. These drive mechanisms are placed at the bottom of the component. Multiple first distance measuring sensors are placed on the side of the component along its length. The drive mechanisms are arranged along both sides of the component's width. The first distance measuring sensors are located on the outer side of the component's side. The multiple first distance measuring sensors are arranged vertically to obtain the distance between the first distance measuring sensors and the upper and lower sides of the component. The first distance measuring sensors send the acquired distance information to a control unit. The control unit is connected to the drive mechanisms and adjusts the actions of the multiple drive mechanisms.
