An instrument digital identification monitoring system

Abstract

The present invention relates to the field of meter recognition, in particular to a meter digital recognition monitoring system, which includes: an imaging device, an automatic meter reading device, and a server; the present invention uses an angle recognition unit to measure the angle between adjacent characters in two images, If it is measured as a non-right triangle, it is recognized that the characters in the image are incomplete, and the image is deleted. If it is measured as a right triangle, the image is identified by the length identification unit, and the length value between adjacent characters is used. Match with the length value stored in the comparison unit to obtain accurate character information, use the comparison unit to compare the information of the two groups of characters before and after, if the two groups of characters are different, transmit to the wireless signal generator, and then pass Sending to the server, so as to avoid the defects caused by manual reading of old mechanical meters or water meters, such as large labor costs, meter reading errors, and untimely statistics.

Description

technical field [0001] The invention relates to the field of instrument identification, in particular to an instrument digital identification monitoring system. Background technique [0002] There are many mechanical electricity meters or water meters in the old city, and the consumption fee is notified to the user through the mechanical electricity meter or water meter, but the person who needs to read the mechanical electricity meter or water meter must personally read the cumulative meter and subtract it from the recorded value The number of last month, and then give the user a bill notification based on the obtained number and the accumulated amount. This reading method has many disadvantages. First, it requires a lot of manpower, and the labor cost is large. There are also errors caused by meter readers. The accumulated quantity is inaccurate, or many problems occur due to reasons such as the absence of the owner and the refusal to read the meter, which affects the time...

[0002] There are many mechanical electricity meters or water meters in the old city, and the consumption fee is notified to the user through the mechanical electricity meter or water meter, but the person who needs to read the mechanical electricity meter or water meter must personally read the cumulative meter and subtract it from the recorded value The number of last month, and then give the user a bill notification based on the obtained number and the accumulated amount. This reading method has many disadvantages. First, it requires a lot of manpower, and the labor cost is large. There are also errors caused by meter readers. The accumulative quantity is inaccurate, or many problems occur due to the owner's absence and refusal to read the meter, which affects the timeliness of the mechanical meter or water meter value statistics
