Abstract

The invention discloses a wireless gas meter reading system, which comprises an optical collecting module and an image identification module electrically connected with the optical collecting module. The image identification module can communicate with a network by GPRS / CDMA; the optical collecting module comprises a lens, an image sensor, an A / D (analog-to-digital) converter and a digital signal processor, all of which are electrically connected in sequence; the image identification module comprises an image preprocessor, an image cutting module, a standardizing module, a graph thinning module, a feature extraction module and a character recognition module which are electrically connected in sequence. The wireless gas meter reading system has the advantages of: obtaining a 100-200 dpi data matrix of the gas meter, having less collected data, and being applicable to a single-chip microcomputer adopting artificial intelligence method for onsite reading of the gas meter. Then data remote transmission is effectively conducted according to the characteristics of a wireless network Zigbee and the GPRS / CDMA (3G) and combining the advantages of the two networks.

Description

technical field [0001] The invention relates to the fields of management and charging in the gas industry, in particular to a gas wireless meter reading system. Background technique [0002] Gas meter reading is an important link in the management and charging of the gas industry. The quality of its management directly affects the economic benefits of an enterprise. At present, most domestic enterprises use manual meter reading, which increases the cost of gas and makes it difficult for the management of the gas company to reach a new level, making it difficult to compete with foreign gas companies. Contents of the invention [0003] Aiming at the above defects, the present invention solves the problems of single function, system crash, dead machine and the like existing in the prior art, and provides a low-cost, high-stability gas meter reading system. [0004] In order to achieve the above object, the present invention is achieved through the following technical solutio...
