Content Description
The invention relates to the technical field of smart energy and smart water, and in particular relates to a water meter automatic meter reading system and method based on image processing technology.
Background of the invention
With the development of information technology and improvement of people’s quality of life, in order to better meet people’s demands for quality of life and to facilitate people’s lives, the state power, water, and gas companies are actively seeking for smart energy technologies and implementation programs. , Smart power, smart water, smart gas on the development of the top priority to change people's traditional way of life. In recent years, the development of smart power has achieved initial success. The power system has taken advantage of its own network construction and has gradually formed a smart power system that integrates remote power purchasing, intelligent power consumption, and automatic meter reading. Although the smart water system has a certain degree of development, the smart IC water meter has a high cost for table replacement and is not a substitute for the traditional mechanical water meter. At the same time, due to the particularity of the water meter and the large amount of blurring and smudging, remote meter reading is caused. The problem of slow speed and low accuracy has become a bottleneck for the further development of smart water.
Summary of the Invention
The present invention overcomes the deficiencies of the prior art and provides an automatic water meter reading system and method based on image processing technology.
The Figure is a structural block diagram of the present invention.
In view of the above technical problems, the technical solution adopted by the present invention is: a water meter automatic meter reading system based on image processing technology, including: a water meter image acquisition module, which is used for collecting digital image information of the water meter surface, and sending the image information to the image Transmission module; image transmission module for compressing images and marking the collected image information, and transmitting the processed image data to a cloud server; a cloud server for receiving image data and classifying and storing according to the mark; water meter image The recognition module locates and identifies the digital position in the image data by merging multi-threshold fuzzy entropy value segmentation method, and sends the recognition result to the intelligent water meter control system; the intelligent water meter control system is used to control the water meter image acquisition module and the recognition result Data processing; water meter image acquisition module connected to the image transmission module; image transmission module connected to the cloud server; cloud server connected to the water meter image recognition module; water meter image recognition module connected to the intelligent water meter control system; smart water meter control system connected to the water meter image acquisition module
The water meter image acquisition module includes a camera. The water meter image recognition module performs digital recognition through the template matching method. The intelligent water meter control system sends a meter reading instruction to the control water meter image acquisition module to obtain the image acquisition time of the water meter image acquisition module; based on the collected recognition results, the cost is calculated and sent to the water meter user.
A water meter automatic meter reading method based on image processing technology, the implementation method includes the following steps: Step one, the meter cover with the water meter image acquisition module and its camera head assembly to the mechanical water meter; Step two, when the smart meter control system issued After the meter reading instruction, the water meter image acquisition module performs an image acquisition on the water meter; Step 3, after the image transmission module compresses the image information, marks and uploads the image data to the cloud server; Step 4: After the cloud server receives the image data, Classify and store according to image tags; Step 5: After the cloud server receives all the water meter images, the water meter image recognition module starts to perform image recognition in sequence, identifies the number in the positioning block through the template matching method, and returns the recognition result to the smart Water meter control system; Step 6: The intelligent water meter control system calculates the cost based on the collected identification results and sends it to the water meter user.
Compared with the prior art, the beneficial effects produced by the present invention are: the present invention solves the problems of surface blurring and smearing of the water meter by using a fusion multi-threshold fuzzy entropy value segmentation image processing method and improves the water meter. The accuracy of automatic recognition reduces the cost of changing the watch. Improve the accuracy of smart meter readings and increase the reliability of smart devices.
