The data accuracy of the data item can be judged according to the score, and the data is sent to the production test software on the computer terminal. The production test software judges whether the returned data is available according to the score range. If the score is too low, it will prompt to identify again or to extract the identified image for manual correction. After obtaining the accurate water meter data item, the number detection is performed according to the water meter number. When there is a duplicate number, the system stops detecting and prompts. If there is no duplicate number, the flow data is set to the intelligent water meter module. Thus, the work efficiency and product quality are greatly improved, and are not affected by the fatigue or replacement of the production personnel.

[0030] Because the driving mechanism 5, the controller 6, the switch 7, the AI vision analysis calculation box 11, the industrial bar light source 20 and the industrial camera 29 are all existing products, therefore, the electrical connection mode between the products, between the products and the computer terminal and between the products and the power supply and the data line or the wire used for the electrical connection are all existing recognized information, therefore, detailed introduction is not made here, meanwhile, because the several groups of electronic products on the equipment are all existing products, therefore, the internal component structure, the working process and the effect are all existing recognized information, therefore, detailed introduction is not made here, and in use, should be used according to the actual situation.

[0031] The electrical components appearing in the text are all electrically connected with the master controller and the 220V mains, and the master controller can be a conventional known device such as a computer which can be controlled.

[0032] The size and shape of all components in the structure are not specifically limited here, and need to be produced according to the actual situation.

[0033] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
