Pulse collection intelligent device in which positive rotation and negative rotation are measured by single sensor

Abstract

The invention discloses a pulse collection intelligent device in which positive rotation and negative rotation are measured by a single sensor. The device comprises a central processing system and a movement. Magnet is rotationally connected with a front of the movement. A pointer is fixedly connected with one side of the magnet. A sensor group is fixedly connected with the front of the movement.The invention relates to the technical field of remote intelligent meter reading. According to the pulse collection intelligent device in which the positive rotation and the negative rotation are measured by the single sensor, the positive rotation and the negative rotation are measured by the single sensor, two magnetic sensitive devices are packaged in the single sensor, so consistency of collection sensitivity of the magnetic sensitive devices is ensured; when the two magnetic sensitive devices leave a factory, relative positions are fixed; the magnetic sensitive devices are integrated in asemiconductor chip, so consistency of a duty cycle of each state is ensured; and even if a magnetic line of force is weakened by aging of the magnet, influence on each magnetic sensitive device is consistent, so the duty cycle of each state under various bad situations is kept relatively stably, and signal missing condition is avoided.

Description

technical field [0001] The invention relates to the technical field of remote intelligent meter reading, in particular to an intelligent pulse collection device for forward and reverse metering with a single sensor. Background technique [0002] Water meters are instruments for measuring water flow. Most of them measure the cumulative flow of water. They are generally divided into two types: volumetric water meters and speed water meters. They originated in the United Kingdom. The development of water meters has a history of nearly 200 years. When selecting water meter specifications, You should first estimate the size and flow range of the flow normally used, and then choose the water meter with the specification that is closest to the value as the first choice. The outside of the gas meter can only see a scroll wheel with numbers in the small glass window. , There are also seven digits on the scroll wheel, the first four digits of the decimal point are black, and the last ...

AI Technical Summary

Problems solved by technology

[0007] Aiming at the deficiencies of the prior art, the present invention provides a single-sensor pulse acquisition intelligent device for measuring forward and reverse, which solves the problems that the meter cannot be measured due to reverse installation and the mechanical reading of the meter is inconsistent with the electronic reading value.
