Description

Technical Field

[0001] The invention relates to the field of gas meter reading, and in particular to a factory intelligent inspection system for a gas meter reading device. Background Art

[0002] When reading the gas meter, you can see the lowest digit wheel slowly turning when using gas. When the lowest digit turns from 0 to 9, the digit wheel in front of it turns, and the reading increases by one number, which is the carry. Obviously, this is also a decimal counting device, called a "roller counter". Although the appearance of the roller is smooth and only has numbers, there is actually a circle of wheels on both sides of each digit (some are hidden in the digit wheel), and there is a small gear next to the adjacent two digits that mesh with the two digit wheels. However, the shape of the small gear is special, and it usually slips, and only drives the digit higher than it to rotate when carrying.

[0003] Generally, due to the lack of indoor space and the limitation of gas pipelines, the installation space left for gas meter reading devices is also very limited. Therefore, it is necessary to measure the three-dimensional solid volume of each newly offline gas meter reading device to determine whether the three-dimensional solid volume of each newly offline gas meter reading device meets the standard, so as to provide reliable reference information for the subsequent installation of each newly offline gas meter reading device. However, the prior art lacks a mature and reliable detection mechanism for detecting the three-dimensional solid volume of each newly offline gas meter reading device. Summary of the invention

It is used to perform a shooting operation on the offline scene of the product offline plate every time a device offline signal is received to obtain and output the corresponding real-time shooting picture, including: the product offline plate of the automated production line is used to place the latest offline gas meter reading device.

[0006] It can be seen that the present invention mainly has the following four significant technical effects: Technical effect 1: Based on the brightness value range corresponding to the gas meter reading device, each component pixel in the received multi-layer enhanced image is analyzed, and based on the imaging depth of field of each component pixel and the imaging focal length corresponding to the multi-layer enhanced image, the distance of each component pixel relative to the imaging lens is determined; Technical effect 2: based on the distances corresponding to the component pixels and the known three-dimensional shapes of the gas meter reading devices, the three-dimensional solid shape corresponding to the latest offline gas meter reading device is determined, and based on the shape information of the three-dimensional solid shape corresponding to the gas meter reading device, the three-dimensional solid volume corresponding to the latest offline gas meter reading device is analyzed; Technical effect three: A multi-layer enhancement mechanism with a targeted structural design including a first enhancement component, a second enhancement component and a third enhancement component is introduced to continuously perform image enhancement actions using logarithmic transformation, edge sharpening actions and recursive filtering actions on the received instant shooting pictures, so as to obtain and output multi-layer enhanced pictures with better picture quality, and provide key data for the subsequent visualization and intelligent identification of the volume of the latest offline gas meter reading device; Technical effect four: A data identification device is introduced to send a size deviation signal when the three-dimensional solid volume corresponding to the latest gas meter reading device off the production line is not within the volume distribution value range of the gas meter reading device of standard size, and to send a size compliance signal when the three-dimensional solid volume corresponding to the latest gas meter reading device off the production line is within the volume distribution value range of the gas meter reading device of standard size, thereby cooperating with the automated production line that produces gas meter reading devices piece by piece to complete the intelligent size inspection of the gas meter reading devices that come off the automated production line piece by piece.

[0007] The factory intelligent inspection system for gas meter reading devices of the present invention has a reliable structure and intelligent design. Since the three-dimensional solid shape corresponding to the latest gas meter reading device off the production line can be determined based on a plurality of visual data selected in a targeted manner, and the three-dimensional solid volume corresponding to the latest gas meter reading device off the production line can be analyzed, reliable reference information can be provided for the subsequent installation of each latest gas meter reading device off the production line.
