Description
Technical field
The present invention relates to remote intelligent meter recording technical field, specially a kind of pulse collection of single-sensor metering positive and negative rotation
Intelligent apparatus.
Background technique
Water meter is the instrument for measuring water flow, is the integrated flow measurement of water mostly, is generally divided into volumetric water meter and speed
Two class of degree formula water meter originates from Britain, and the development of water meter has nearly 200 years history, when selecting water meter specification, should first estimate
Then the size and range of flow of used flow under normal conditions selects the water of that specification of the common flow closest to the value
Table is used as first choice, and can only see outside gas meter, flow meter has the idler wheel with number in small windowpane, also has seven bit digitals on idler wheel,
Four black before decimal point, rear three red, the daily fuel cooked of people from the serious waste of resources such as firewood, coal,
Seriously polluted conventional energy resource is changed into natural gas and coal gas, the even clean energy resourcies such as electricity, and gas meter, flow meter will be sent out herein
Its effect, its automatic accumulating function are waved, so that those are known in which can be convenient using other of natural gas or piped gas
With how many combustion gas, to pay the fees according to the cubic meter number for monthly consuming combustion gas.
There are mainly two types of the methods for judging water meter and gas meter, flow meter positive and negative rotation currently on the market:
1. using two sensors, this method has the disadvantage that the consistency 1. needed to magnetic-sensitive elements and magnet
Strictly screened；2. the installation site and mounting distance to magnetic-sensitive elements have strict demand, need to carry out thousands of times
Test, as long as and structure change it is necessary to re-start to test and determine installation site and distance, the aging of magnet can allow magnetic
The timing of the signal condition of Sensitive Apparatus output changes, and mistake occurs so as to cause judgement of the module to the positive and negative rotation of table and goes out
Existing electromechanical inconsistent phenomenon, the manufacturing technique requirent of meter is too high to will lead to that the production cost increases, so that it is competing to lose meter
Strive advantage；
2. this method has the disadvantage that the gear band of meter mechanical part carries using three or three or more sensors
Ability and the magnetic line of force distribution situation of magnet result in that magnet pointer size is smaller, leave the inductive spacing phase of magnetic-sensitive elements for
To narrow, distance is too close between magnetic-sensitive elements, and especially when flow is bigger, quickly, duty ratio is small for magnet pointer revolving speed,
The case where causing magnetic-sensitive elements to will appear state missing, the data of acquisition will inaccuracy, and use three or three with
On sensor when, cause a series of problems, such as power consumption is big, at high cost, fault point is mostly and vulnerable to interference.
