Embodiment Construction

[0018] Now in combination with Fig. 1, Fig. 2 and Fig. 3, the detection water is taken as the fluid source as an example. Connect tap water from the water inlet end of pipeline 18, and water enters from this end. The solenoid valve 14 is opened by giving the water inlet signal switch in the microcomputer control system 1, the meter clamp 15 clamps the meter 17 to be tested, the water enters the water through the pipeline 18 on the machine base 16, and the flow of the water is adjusted by the flow regulating valve 10. The instantaneous flow meter 9 measures the instantaneous flow, and the switch solenoid valve 8 controls the opening or closing of the water. The water in the pipeline 18 enters the working volume 4 and the working volume 6 respectively, and is discharged by the bottom valve 5 when draining. The photoelectric liquid level sensor 3 and the camera 7 feed back the liquid level in the work gauge to the training module and the identification module. A light 12 is sus...

Abstract

The present invention relates to a device for detecting flow standard by using image camera technique, belonging to the field of flow standard detection technology. Said device includes image camera type automatic reading system, software processing portion and image camera peripheral equipment whose action is controlled by software, in which the kernel portion is processing process of software, the fluid source is connected with detected meter. The flow meter for sampling detected meter by adopting image camera technique can adopt two lines to make connection, one line is connected with regulation module and another line is connected with identification module. Said regulation module is composed of sample collection unit, image processing unit and statistical template unit. The regulation data measured by said module can be connected with background database, then connected with matching unit. Said invention can be matched with various flow standard devices.

Description

technical field [0001] The invention relates to the field of flow standard detection, and relates to a device for detecting flow standard by camera technology. Background technique [0002] With the development of computer and artificial intelligence, image processing and pattern recognition have been developed and widely used in more and more fields. A complete image processing application system needs to use digital camera technology, digital image processing technology, pattern recognition and artificial intelligence technology. Some applications also require computer information management technology. [0003] Similarly, with the improvement of the informatization of the whole society, these advanced technologies also need to be introduced in the measurement industry to improve efficiency and reduce costs. In the verification work of flow meters, it is easy to realize automatic detection for those with electric signal output, and for direct-reading flow meters without ...
