Embodiment Construction

[0041] The present invention will be further described below in conjunction with accompanying drawing:

[0042] Such as figure 1As shown, this embodiment is mainly composed of three parts: system self-power generation, water meter data collection, data wireless transmission and display. The micro permanent magnet brushed DC generator completes the self-produced power part of the system; the control chip ATmega8 obtains the water meter data through the detection of the photocell and simultaneously completes the data processing and wireless transmission; the 433MHz serial port module completes the wireless transmission of data. The receiver realizes the reception, storage and display of water meter data.

[0043] Such as figure 2 The overall structure frame of this embodiment Figure four Groups of photocells are fixedly installed on both sides of the code disc of the water meter, and each group of photocells is composed of five pairs of infrared emitting tubes. The deflect...

Abstract

A wireless meter reading system of a power-free water meter can solve the technical problems that traditional manual meter reading is low in efficiency and large in workload, and comprises a water meter data collecting module, a data transmitting module and a receiver module which are sequentially connected. The water meter data collecting module is arranged beside a water meter encoder. The wireless meter reading system further comprises a self power generation module which is connected with the water meter data collecting module. A miniature water flow power generator is adopted as the self power generation module and arranged in a water pipe. The wireless meter reading system further comprises a power management module which is connected with the self power generation module, the water meter data collecting module and the data transmitting module. The wireless meter reading system has the advantages that the system does not need to be powered externally, and the electric energy required by the system is generated when water flow passes through the miniature permanent magnetic type DC power generator; water meter data is wirelessly transmitted, and meter reading personnel can obtain current values and historical values of the water meter data near the water meter through the receiver device; the water meter data is automatically recorded in the management system without complex manual recording.

Description

technical field [0001] The invention relates to a meter reading system, in particular to a wireless meter reading system for water meters without power supply. Background technique [0002] With the continuous advancement of my country's urbanization process, household water has changed from one household to one provided by enterprises for individuals or units. The method of "one household, one meter, meter measurement" is still the company's main method of measuring household or unit water consumption. This traditional method works well when the number of water meters is small and the location is relatively concentrated. However, when the location of the meters is relatively scattered and the number of water meters is large, the problems of this method of meter reading by specialized personnel will be revealed. come out. For example, the location of the water meter is remote, the environment of the water meter is bad, and the arrangement of the water meter is scattered, w...
