Description
Technical field
This utility model relates to a kind of novel electric-mechanic control system formula intellectual water meter, is the positive counterplot of a kind of band in particular
Amount function and the valve control intelligent water meter of dynamo-electric separate type.
Background technology
Current electric-mechanic control system formula intellectual water meter uses built-in sensors to count mostly, and this sensor is placed in band valve base table originally
Internal, valve control motor is then arranged in the plastics back box being fixed on band valve base table body, and aforesaid way product is breaking down
In the case of, either band valve base table or electronic section, it is required for whole table is disassembled carrying out keeping in repair and changes；It addition, it is right
The sampling of mechanical signal and be single magnetic induction or double magnetic induction way, principle of signal conversion be band valve base table intrinsic certain
Installing a magnetic pointer on gear, when magnetic indicators turn one encloses, built-in sensors obtains one or a pair pulse switch letter
Number, it is transferred to electronic measurement module by holding wire and carries out cumulative and calculate the water volume by water meter.This sample mode
Do not differentiate water (flow) direction, so no matter water meter is to rotate forward or reversion, the signal that electronic measurement module all can be collected
Being defined as useful signal to add up, when there is Reversion, mechanical water meter is a negative metering, and electronic measurement part is still
It is just to measure, dynamo-electric error, i.e. electromechanical reading will be caused inconsistent, and the twice that this error is the reverse usage amount of water meter, water
Table reversely uses the most, and dynamo-electric error is the biggest, so will bring a lot of trouble to datumization management.
Summary of the invention
In order to overcome the most inconsistent shortcoming of current electric-mechanic control system formula intellectual water meter maintenance difficult, electromechanical reading, this
The purpose of utility model is to provide a kind of dynamo-electric valve control intelligent water meter separated and the method for the positive and negative metering of energy.
This dynamo-electric valve control intelligent water meter separated, it is characterised in that: electronic section is kept completely separate with band valve base table body,
External sensor is fixed on the plastic structural part of electronic section；In the circumference of external sensor, 3 deciles is disposed with 3 groups
Magnetic induction device, the circumference of magnetic induction device is relative with the circumference of the sender magnet steel on band valve base table intrinsic magnetic pointer
Should.
Electronic section is encapsulated in plastic structural part.
Principle of the present utility model:
Sense the magnetic induction device on trigger sensor by the sender magnet steel on magnetic pointer in valve control base table and obtain
Pulse signal: as a example by three groups of magnetic induction devices, owing to using three groups of magnetic induction devices, respectively A, B, C, turns at magnetic pointer
During Dong, three groups of magnetic induction devices are triggered and just have a corresponding priority in proper order: be triggered with A magnetic induction device
For starting point, when water meter main story, magnetic finger clockwise rotate, such magnetic induction device be A → B → C → A → B →
C .... sequential loop be triggered successively, water meter reversion time, magnetic pointer rotates counterclockwise, and such magnetic induction device is A
→ C → B → A → C → B .... sequential loop be triggered successively, such electronic measurement module is just provided with depending on of Orientation
According to, its travel direction can be distinguished and then draws the water yield of rotating；When pointer turns round between certain two magnetic induction device
Dynamic, i.e. dither state, and when not meeting a circulation triggering, electronic measurement module is will not be to this output signal after analyzing it
Carry out accumulation calculating, and when certain two or three magnetic induction device is triggered, and it will be carried out by electronic measurement module simultaneously
Response, distinguish its be malfunction thus carry out close valve events, stop occur interference or fault cause band valve base table with water
The situation that electronic measurement module does not counts occurs, it is ensured that its electromechanical reading is consistent.
Advantage of the present utility model: 1, using the mode that valve control base table is kept completely separate with electronic section, electronic section can thing
First being assemblied in plastic structural part, carry out with band valve base table when producing simultaneously, last need to be with screw by solid for two parts locking
Fixed；So when water meter uses process to break down, only it need to be analyzed electronic section or band valve base exterior portion
Dividing and break down, selectivity carries out maintenance and changes, and different common machine is electrically coupled valve control intelligent water meter either which part of formula to be gone out
Existing fault all needs whole table is disassembled maintenance, is producing and is all being greatly saved cost in use cost.2, due to magnetic inductor
Part order is installed, it can be deduced that the water yield of rotating, it is ensured that its electromechanical reading can be accomplished completely the same.
