Abstract
The utility model discloses an electromechanical conversion signal acquisition device of a water meter, which comprises a rotational shaft connected to a rotational character wheel of a base of the water meter, wherein the top of the rotational shaft is fixedly connected with a magnet; and a double-full-bridge type sensor electrically connected with a single chip microcomputer is arranged above the magnet. According to the electromechanical conversion signal acquisition device used for converting signals of a mechanical part and an electronic part of the water meter, the magnet rotates by taking the rotational shaft as a circle center, the rotational shaft is mounted on the rotational character wheel of the base of the water meter, and when water flows through the water meter at a certain flow speed, an impeller of the water meter rotates and drives the rotational shaft to rotate through being coupled with a gear; when the magnet rotates in different positions, the sensor can sense different magnetic flux; the double-full-bridge type sensor counts and outputs signals through judging the position of the magnet; and the signals are transmitted to the single chip microcomputer through a signal line. The electromechanical conversion signal acquisition device has a compact structure, can acquire the signals conveniently and accurately and is easy to popularize.
Description
Technical field
The utility model relates to the dynamo-electric switching signal harvester of a kind of water meter.
Background technology
The dynamo-electric switching signal harvester of the water meter that adopts at present majority is the double dry-reed pipe collection, and its two contacts are processed by special material, are encapsulated in the glass tube of vacuum.As long as near it, two nodes of tongue tube will be pulled together, and make circuit turn-on with magnet.Tongue tube damages the glass tube of sealing easily and influences the AT value in the Pipe Cutting pin.In welding, if the temperature of welding is too high, the distance of high temperature meeting influencing contactor that is to say the sensitivity that can change tongue tube.Cause tongue tube to become useless pipe. gather less than the signal of signal or collection incorrect.
The utility model content
The purpose of the utility model is to above-mentioned situation, and the dynamo-electric switching signal harvester of water meter of the accurate acquired signal of a kind of convenience is provided.
The purpose of the utility model realizes through following technical proposals:
The dynamo-electric switching signal harvester of a kind of water meter; Comprise the rotation axis on the rotation character wheel that is connected essentic-water-meter; Said rotation axis top is fixedly connected magnet, and said magnet top is provided with the bridge type magnetic sensor of enjoying a double blessing, said enjoy a double blessing bridge type magnetic sensor and single-chip microcomputer electrical connection.
