Embodiment
The present invention is further described below by specific embodiment; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the principle of the invention; can also make some modification and improvement, these also should be considered as belonging to protection scope of the present invention.
Traditional mechanical type water meter as shown in Figure 1, impeller is promoted by current and rotates, the train of reduction gears of impeller top simultaneously, and according to the revolution ratio between gear, reach the purpose of volume metering.
As shown in Figure 2, the counter 5 of mechanical type water meter comprises moving mark 6, pointer 7 and character wheel three parts.Moving mark 6 directly is connected the wheel rotation axle, and its purpose is showing the wheel rotation situation.Pointer 7 represents 0.1 liter to 100 liters four kinds of different volume markings respectively.The volume of character wheel representative 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 type water meter, sets up sensing component 1 and flow monitoring register 2 on the basis of traditional mechanical type water meter, and as shown in Figure 3, sensing component 1 comprises sensing component 1 and sensing component 24.Sensing component 1 is located at moving mark 6 tops, and major function is in sensing wheel rotation situation.In case of necessity, can also judge the rotating of impeller.Sensing component 24 is located at any pointer 7 top, and major function is obtaining water meter actual volume changing value.
Sensing component is that magnetic strength is surveyed assembly or non-magnetic strength is surveyed assembly.It is mechanical realization assembly or electronics sensing component that magnetic strength is surveyed assembly.The mechanical realization assembly is tongue tube.The electronics sensing component is Hall subassembly.
Sensing component 1 with wheel rotation signal and volume change signal, is real-time transmitted to flow monitoring register 2 by connection.Through signal processing, analysis, calculation, record, with communication interface data are exported at last.As the measured data of estimating the leakage loss water yield backward.
This device is installed in the rotation signal that moves magnet on mark 6 and the pointer 7 by two sensing component sensings, analyzes the pulse signal that above-mentioned sensing component 1 is transmitted with flow monitoring register 2.Via the signal fusing between two sensing components, calculate high instantaneous flow value of resolving.Concrete operational process is as follows:
When water meter turbine rotated, sensing component 1 was exported pulse signal or switch signal with correspondence.This moment, flow monitoring register 2 will be according to the revolution ratio of default sensing component 1 with sensing component 24, converts and learn that sensing component 1 sends the instantaneous flow value of pulse signal representative.Analyze the positive-negative rotation state of impeller simultaneously, and with all data record one by one.
When the water meter volume of flowing through is enough to drive sensing component 24 output pulse signal or switch signals.Flow monitoring register 2 will be revised the accumulated water volume bulking value accordingly.Simultaneously, verify again whether sensing component 1 and the revolution ratio of sensing component 24 change.As change, flow monitoring register 2 will be revised correlation parameter automatically.As the foundation of handling sensing component one 3 pulse signals next time.
When setting the period or initiatively requiring, flow monitoring register 2 with the accumulated water volume of institute's record and moment data on flows, be sent to control center by communication interface such as GPRS.Also can assign the special messenger directly to download data to the scene or can install portable pen recorder such as SD card additional at flow monitoring register 2, by the special messenger to the on-the-spot portable pen recorder of changing.With manual type storage data is taken back control center.
