Description
Technical field
Duct survey field is the utility model is related to, in particular to a kind of water meter testing agency and water meter.
Background technology
Current electric-mechanic control system formula intellectual water meter is counted using base table built-in sensors mostly, or is installed additional on water gage glass
Sensor.Sensor is placed in band valve base table body, and valve control motor, which is then installed on, is fixed on the plastics back box with valve base table body
On, aforesaid way built-in sensors product in case of a failure, either with valve base table or electronic section, is required for
Whole table is disassembled and is replaced to carry out maintenance；Sensor, which is installed on water gage glass upper end, then not only influences water meter verification, test
With type approval etc., and production cost is high, framework and complex process.
In addition, sampling of the existing intellectual water meter to mechanical signal and be single magnetic induction or double magnetic induction ways, signal turns
It is the magnetic pointer of installation one on band some intrinsic gear of valve base table to change principle, built-in when magnetic indicators turn one encloses
Sensor obtains one or a pair of of pulse switch signal, and being transferred to electronic measurement module by signal wire is added up and calculated
Pass through the water volume of water meter.
But above-mentioned this sample mode does not differentiate water (flow) direction, so no matter water meter is rotating forward or reversion, electricity
The signal that sub- metering module can all be collected is determined as useful signal and adds up, when there is Reversion, mechanical water

Answer the circumference of device corresponding with the circumference with the sender magnet steel on the intrinsic magnetic pointer of valve base table.By in valve control base table
Sender magnet steel on magnetic pointer senses the magnetic induction device on trigger sensor and obtains pulse signal：Three groups of magnetic induction devices
It is triggered and just has a corresponding priority in proper order：Its travel direction can be distinguished and then draw the water of rotating.
However, above-mentioned valve control intelligent water meter, in order to realize that rotating measures, its sensor is configured with three groups, respectively circumferentially
Ground is arranged in the top of base table dial plate, its one side, which has dial plate, blocks, and is an impediment to automation school of the relevant unit to base table
Right, it is big and complicated that another aspect base table coordinates the needle needs of sensor to design.

First embodiment
Fig. 1 is refer to, present embodiments provides a kind of water meter testing agency 600, it includes watchcase 100 and lower watchcase
200, the upper watchcase 100 and the lower watchcase 200 connect, corresponding position on the upper watchcase 100 and the lower watchcase 200
It is provided with the cavity for being arranged 700 dial plate of base table.
Fig. 2 and Fig. 3 are refer to, in the present embodiment, close to the sky between the upper watchcase 100 and the lower watchcase 200
The position of chamber is built-in with the plate mounting groove 130 for installing PCB circuit board, and the first magnetic sensing is provided with the PCB circuit board
Device A and the second Magnetic Sensor B.In the present embodiment, the Magnetic Sensor can be coil or magnetic switch.
Under the water meter testing agency 600 is in running order, specifically, when the needle in 700 dial plate of base table
500 close to the first Magnetic Sensor A when, the first Magnetic Sensor A exports the first electric signal；When 700 dial plate of base table
When interior needle 500 is close to the centre position of the first Magnetic Sensor A and the second Magnetic Sensor B, first magnetic passes
Sensor A exports the first electric signal, and the second Magnetic Sensor B exports the second electric signal；When in 700 dial plate of base table
When needle 500 is close to the second Magnetic Sensor B, the second Magnetic Sensor B exports the second electric signal.
It is understood that in the present embodiment, when the needle 500 in 700 dial plate of base table is (clockwise or inverse in the first direction
Hour hands) when rotating, the microcontroller (can also be the external control unit of PCB circuit board) in the PCB circuit board receives
Signal sequence is successively：First electric signal；First electric signal and the second electric signal；Second electric signal.On the contrary, work as the needle
500 along second direction opposite to the first direction rotate (counterclockwise or clockwise) when, the monolithic in the PCB circuit board
The signal sequence that machine receives is successively：Second electric signal；Second electric signal and the first electric signal；First electric signal.Therefore, it is single
Piece machine by the first Magnetic Sensor A under the above situation and the second Magnetic Sensor B output three kinds of various combination signals when
Between sequentially differentiated, you can identify the rotating of needle 500 in 700 dial plate of base table.
It should be noted that in the present embodiment, the microcontroller in PCB circuit board receive by the first Magnetic Sensor A with
The order of the electric signal of second Magnetic Sensor B outputs, includes but are not limited to both the above situation.It is understood that due to
Forward and reverse shake in short time may occur for dial plate needle 500, and the order for exporting electric signal in this case is probably
A certain signal or certain two kinds of signal continuously repeat triggering, and at this time, water meter testing agency 600 provided in this embodiment can be set
Occur just can once be counted to need to receive three kinds of different electric signal combinations, therefore can be to avoid because needle 500
Error count caused by shake.
In the present embodiment, the first Magnetic Sensor A is the first magnetic switch, and the second Magnetic Sensor B is the second magnetic

During the centre position of two magnetic switch, the first electric signal of the first magnetic switch output, and second magnetic switch are defeated
Go out the second electric signal；When the needle 500 in 700 dial plate of base table is close to second magnetic switch, second magnetic control
Switch the second electric signal of output.
In the present embodiment, it is preferred that first magnetic switch is the first tongue tube, and second magnetic switch is second
Tongue tube.The tongue tube is a kind of passive electronic switch element for having contact, it is small easy to control with simple in structure
The advantages that processed, its shell are usually the glass tube of a sealing, and the elastic spring battery plate of two ironys is housed in pipe, is also inoculated with lazy
Property gas.Under original state, the reed made of special material of two in glass tube is to separate.When the material that is magnetic is close
During glass tube, under the influence of a magnetic field, two reeds in pipe are magnetized and contact of attracting each other, and reed will be pull-in on one
Rise, the circuit communication for being connect node；After outer magnetic force disappears, two reeds are separated due to the elastic of itself, and circuit disconnects.
Specifically, when the needle 500 in 700 dial plate of base table is close to first tongue tube, the first dry spring
The switch closure of pipe, exports the first electric signal；When the needle 500 in 700 dial plate of base table close to first tongue tube and
During the centre position of second tongue tube, the switch of first tongue tube and the switch of second tongue tube close,
First tongue tube exports the first electric signal, and second tongue tube exports the second electric signal；When 700 table of base table
When needle 500 in disk is close to second tongue tube, the switch closure of second tongue tube, exports the second electric signal.
Referring to Fig.1 and 2, in the present embodiment, the signal section for built-in aerial is also convexly equipped with the upper watchcase 100
120, the interior PCB circuit board set of the plate mounting groove 130 is electrically connected with the antenna built in the signal section 120.
