Water meter needle pointing recognition device and water meter remote meter reading device

Abstract

The invention relates to a water meter needle pointing recognition device. The water meter needle pointing recognition device is installed above round scales of a water meter and comprises a base, a plurality of light-emitting diodes and a corresponding receiver which can receive lights of the light-emitting diodes, the receivers are arranged in the middle of the center of the base, the light-emitting diodes are distributed around the center of the receiver as the center, and there exist two light-emitting diodes which can irradiate a pointing part of the needle of the water meter when started; when the device is operated, the light-emitting diodes are switched on in turn and switched off, signals of different light-emitting diodes at different timings, and the pointing direction of the needle of the water meter is judged according to the signal reflecting intensity of all signals. The device can be directly installed on an existing mechanical water meter gauge, water meter water amount data is automatically recognized at a set timing, the data is transmitted outwards, and remote meter reading is achieved. The device has the advantages that labor force, materials and time spent onmanual water reading are saved, the converting of an original mechanical water meter can be prevented, converting labor force and finance resource can be saved, and the meter reading device has the advantages of low power consumption and long service life.

Description

technical field [0001] The invention relates to the field of water meters, in particular to a water meter pointer identification device. At the same time, the invention also relates to a remote meter reading device for water meters. Background technique [0002] At present, there are mainly two types of water meters for residents. One is the new digital water meter, which is powered by batteries, and automatically collects data such as water volume at regular intervals and uploads it to the server; the other is the old traditional mechanical water meter. The data collection of the water meter requires manual collection. . Although digital water meters have the advantage of saving manual meter reading steps compared to mechanical water meters, there are still a considerable number of users using traditional mechanical water meters. The main reason is that the old mechanical water meters have not yet expired It can be used. If you want to refit the water meter, it will also ...

Problems solved by technology

[0002] At present, there are mainly two types of water meters for residents. One is the new digital water meter, which is powered by batteries, and automatically collects data such as water volume at regular intervals and uploads it to the server; the other is the old traditional mechanical water meter. The data collection of the water meter requires manual collection.

Although digital water meters have the advantage of saving manual meter reading steps compared to mechanical water meters, there are still a considerable number of users using traditional mechanical water meters. The main reason is that the old mechanical water meters have not yet expired It can be used. If you want to refit the water meter, it will also involve the cost of new water meter equipment, rare professional refitting workers, refitting labor costs, and time costs. These conditions determine that the replacement of water meters is not only expensive, but also time-consuming and laborious. Therefore, relevant The department has been in a slow state on the transformation of the water meter
