Remote meter reading system

Abstract

The invention provides a remote meter reading system, and relates to the technical field of communication. The remote meter reading system provided by the invention uses a Halle element and an acquirer matched with magnetic steel, the acquisition module is fixed on a mechanical character wheel through the magnetic steel to be matched with the Hall element (a sampling plate) so that the magnetic steel can rotate along with the rotation of the mechanical character wheel, and then a magnetic field emitted by the magnetic steel can be rotated; the sampling plate is capable of producing a sampling signal to finish the signal acquisition when the magnetic steel rotates to an appointed position. Compared with a reed switch, for the remote meter reading system, the Hall element is free of the mechanical failure, the reliability of the Hall element is higher than that of the reed switch, the service life is longer, the remote meter reading system is capable of accurately reading the scale of a meter, and the defect caused by the condition that the reed switch is used for signal acquiring in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a remote meter reading system. Background technique [0002] In daily life, the consumption of resources such as water, gas and electricity is inseparable. The water meter and gas meter in the home automatically count the water and gas consumption of the household to form the total consumption of water energy and natural gas of the household in a certain period of time. Water conservancy companies and natural gas companies calculate the consumption of water energy and natural gas within a period of time based on the difference between the results of the last meter reading and the current meter reading, and then determine the amount of charges based on the unit price. [0003] At present, the charging methods of meter reading for users in domestic residential areas mainly include manual meter reading by meter readers, meter reading by meter readers with POS, and IC card mete...

AI Technical Summary

Problems solved by technology

The reliability of the collector using a reed switch for sampling is related to the following aspects: the reed of the reed switch gradually loses its elasticity, which leads to a decrease in reliability until it fails, and then pulse sampling cannot be performed; The layer protection metal is worn out due to multiple contacts, resulting in reduced reliability until failure, and then pulse sampling cannot be performed; the reed of the reed switch is aging due to multiple voltage and current effects, resulting in reduced reliability until failure, and then pulse sampling cannot be performed

[0010] In summary, because the sampling module in the existing collector uses a reed switch for sampling, the reed switch cannot effectively generate metering signals with the extension of the use time of the reed switch, which leads to the failure of the collector to work normally.
