Embodiment
Below by specific embodiment, the present invention is further described; it should be pointed out that for the person of ordinary skill of the art, under the premise without departing from the principles of the invention; can also make some modification and improvement, these also should be considered as belonging to protection scope of the present invention.
As shown in Figure 1, impeller is rotated by water jet propulsion traditional mechanical water meter, the train of reduction gears simultaneously above impeller, and according to the revolution ratio between gear, reaches the object of volume metering.
As shown in Figure 2, the counter 5 of mechanical water meter comprises dynamic mark 6, pointer 7 and character wheel three part.Dynamic mark 6 is directly connected wheel rotation axle, and its object is in display wheel rotation situation.Pointer 7 represents 0.1 liter to 100 liters four kinds different volume markings respectively.Volume representated by character wheel is stere, the foundation of Here it is Running-water Company's counting cost by gas meter.
The present invention is used for the flow monitoring device of mechanical water meter, and the basis of traditional mechanical water meter is set up sensing component 1 and flow monitoring register 2, and as shown in Figure 3, sensing component 1 comprises sensing component 1 and sensing component 24.Sensing component 1 is located at above dynamic mark 6, and major function is in sensing wheel rotation situation.If desired, the rotating of impeller can also be judged.Sensing component 24 is located at above any one pointer 7, and major function is obtaining water meter actual volume changing value.
Sensing component is magnetic sensing component or non-magnetic sensing component.Magnetic sensing component is mechanical realization assembly or electronics sensing component.Mechanical realization assembly is tongue tube.Electronics sensing component is Hall subassembly.
Sensing component 1, by connection, by wheel rotation signal and volume change signal, is real-time transmitted to flow monitoring register 2.Through signal process, analysis, calculation, record, finally with communication interface, data are exported.As the measured data estimating the leakage loss water yield backward.
This device is installed in the rotation signal of magnet on dynamic mark 6 and pointer 7 by two sensing component sensing, analyzes with flow monitoring register 2 pulse signal that above-mentioned sensing component 1 transmits.Via the signal fusing between two sensing component, calculate high instantaneous flow value of resolving.Carrying out practically process is as follows:
When water meter turbine rotates, correspondence is exported pulse signal or switch signal by sensing component 1.Now flow monitoring register 2 is by according to presetting the revolution ratio of sensing component 1 with sensing component 24, converts and learns that sensing component 1 sends the instantaneous flow value representated by pulse signal.Analyze the positive-negative rotation state of impeller simultaneously, and by all data record one by one.
Be enough to drive sensing component 24 to export pulse signal or switch signal when flowing through water gauge body accumulated amount.Flow monitoring register 2 will revise accumulated water volume bulking value accordingly.Meanwhile, again verify whether sensing component 1 changes with the revolution ratio of sensing component 24.As changed, flow monitoring register 2 is by auto modification correlation parameter.As the foundation processing sensing component 1 pulse signal next time.
When setting period or initiative, flow monitoring register 2 by the accumulated water volume that records and moment data on flows, by communication interface as GPRS is sent to control center.Also special messenger can be assigned to the direct downloading data in scene or portable pen recorder can be installed additional as SD card on flow monitoring register 2, by special messenger to spot replace portable pen recorder.To manually storage data is taken back control center.
