Embodiment
The utility model is used water flow generator that the mechanical energy of fluid in water pipe is converted into electric energy, through energy collecting chip and mu balanced circuit by voltage voltage stabilizing to 5V to lithium cell charging, the advantages such as lithium battery has that energy comparison is high, long service life, self-discharge rate are very low, environmental protection.What this works lithium battery was used is 3.7V lithium battery, and therefore needing booster circuit is single-chip microcomputer power supply by boost in voltage to 5V.Flow monitoring adopts is the judgement that the frequency pulse signal of detecting turbine rotation is realized uninterrupted, and temperature sensing part is that what to adopt is that DS18B20 temperature sensor is realized, and bluetooth module is for sending to the information such as flow, temperature, charging at PC end.
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail:
As shown in Figure 1, water pipe connects water flow generator and flow detection module successively, the output terminal of water flow generator is connected to single-chip microcomputer through energy collecting chip, electric power storage module, booster circuit successively, the output terminal of flow detection module is connected to single-chip microcomputer, and the output terminal of single-chip microcomputer is connected with liquid crystal display.Single-chip microcomputer is also connected with temperature sensor, and the model of described temperature sensor is DS18B20.The output terminal of single-chip microcomputer is also connected with bluetooth sending module.
As shown in Figure 2, input voltage range is 7V to 40V to energy collecting chip LM2575 connection diagram, inputs 1 pin and connects suitable electric capacity to ground conduct input; Output terminal 2 pin need connect diode and inductance as peripheral circuit member, feed back to 4 pin simultaneously.The stable single-chip microcomputer of exporting to that finally obtains 5V is powered.LM2575 series switch integrated regulator is the 1A integrated stable voltage circuit that National Semiconductor produces, its inner integrated fixing oscillator, seldom peripheral components just can form a kind of efficient mu balanced circuit, can greatly reduce the volume of heat radiator, and in most of the cases not need heat radiator; There is perfect holding circuit inside, comprises current limit and hot breaking circuit.Chip can provide external control pin, is the desirable substitute products of traditional trifocal integrated regulator.
This electricity generation module adopts high energy efficiency generator and the electricity separation technology without magnetic resistance, the clutch coupling of exclusive double magnetic circuit coupling, and volume only has 4/5 of common minisize hydroelectric generator, during load short circuits, also can start smoothly.There is high cost performance.Operation hydraulic pressure: 0.08 ~ 0.45 MP output voltage: 9.8 ~ 18.5VDC/ is unloaded, 8.8 ~ 15VDC/0.1 K load output current: 128 ~ 260 MA/0.1 K loads, flow loss: during 3.6%(0.25 MP).
As shown in Figure 3, this emulation is mainly the emulation of analog detection discharge and temperature.Emulator carries the realistic model of 18b20, realizes unibus data and reads, then displays temperature on 1602 liquid crystal displays in the driving of single-chip microcomputer internal composition 18b20.According to Hall element, work is the principle that produces square wave, uses the generation of signal generator simulation square wave, and single-chip microcomputer gathers square wave number, changes into flow, in liquid crystal screen display by functional operation.
Relation between pressure, output voltage and flow velocity is as shown in Figure 4, Figure 5:
As shown in Figure 4, flow and pressure are substantially proportional, and working pressure increases along with the growth of flow.The relational expression that can simulate according to the data of three test gained is as follows:
Flow rate of water flow Q (L/min)

Flow pulse feature F=C1*Q-C2
(through measured curve matching, obtaining C1=7.5, C2=3)
Actual experiments of measuring is divided into take bucket as water source and take tap water as water source two, and experimental result is as follows:
One, when bucket is lifted differing heights, water flow velocity is different, and the voltage value on liquid crystal display also has corresponding variation.Concrete data are as follows:
| Highly/m | Flow velocity l/min | Flow pulse F/hz | Output voltage/v |
| 0.8 | 1.3 | 4.2 | 1.8 |
| 1.5 | 2.2 | 11.4 | 3.3 |
| 2 | 3.4 | 20.0 | 3.8 |
| 3 | 4.8 | 26.7 | 5.6 |
Because water flows down from bucket, output voltage is relatively little.
Two, water pipe is directly received water swivel place, guarantees that water flow velocity is larger, can obtain larger output voltage.When water swivel reaches in various degree, water flow velocity is different, and the voltage value on liquid crystal display also has corresponding variation.Concrete data are as follows:
| The degree of turning on the tap | Output voltage/v |
| Little | 5.2 |
| In | 10.5 |
| Greatly | 18.2 |
Output voltage meets design needs.
