Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Shown in Fig. 1, Fig. 2 and Fig. 3, according to the dome-type top crown 1 of the size design electric capacity energy collecting transducer of the upper mark of figure, the radius of dome-type top crown 1 is 20cm therein, adopt 304 stainless steels to make, thickness is 0.4mm, for ease of three insulation columns 3, upper and lower pole plate 1,2 is carried out to bracing reinforcement, outer rim in top crown dome-type structure increases by an edge, outer rim radius is 21.2cm, on outer rim stainless steel, be uniformly distributed the boring of 3 diameter 8.5mm, and with M8 nut with fixed insulation pillar 3.Fig. 4 is the bottom crown vertical view of condenser type energy collecting transducer, by the size marking on this figure, designs, and adopts HPb-62 brass material, and thickness is 2.5mm.The thickness of bottom crown 2 will have two: one apparently higher than the reason of top crown 1, and top crown dome-type structure adopts the material of thinner thickness more easily to process, the 2nd, bottom crown 2 thickness increase, quality obviously increases, and the center of gravity of this energy collecting transducer is reduced to the stability that can effectively improve device.
The modulate circuit schematic diagram that Figure 5 shows that condenser type energy collecting conversion equipment, this circuit can be divided into three parts as we can see from the figure: rectification, storage and voltage stabilizing feedback circuit.What wherein rectification circuit adopted is the single-phase rectification bridge that 1N4001 diode forms, and storage capacitance adopts the aluminium electrolytic capacitor of 16V/1F to receive on Ustore binding post, the charge-trapping at energy collecting transducer two ends can be got up, and is stored on electric capacity.Termination P6KE15CA bi-directional voltage stabilizing diode after electric capacity, its object is for preventing the too high initiation potential of storage capacitor both end voltage, the maximum power of this bi-directional voltage stabilizing pipe can reach 500W, and the power that front end condenser type energy collecting transducer is collected is very little, do not reach the maximum power of diode completely, meet circuit design demand.In voltage stabilizing feedback circuit, adopt the voltage stabilizing circuit forming based on nanowatt level micro power-consumption chip BQ25504, the output of circuit adopts two-way output ，Yi road to connect 3V rechargeable battery ，Yi road and connects wireless sensor network.Wherein adopt energy-storage battery as the stand-by power supply of whole circuit.When wireless senser networking is during in resting state, its power consumption is very low, and the energy that condenser type energy collecting conversion equipment is collected can temporarily be stored on energy-storage battery; When wireless sensor network is during in emission state, its power consumption increases, if the energy shortage that now condenser type energy collecting conversion equipment is collected is when meeting circuit working, energy-storage battery will play a role.Sort circuit design can guarantee reliability and the fail safe of whole system work.The feature of this modulate circuit is low in energy consumption, and collection of energy ability is outstanding, and the voltage that is transported to storage capacitor two ends when electric capacity energy collecting transducer is during higher than 330mV, and circuit just starts startup work.
Condenser type energy collecting conversion equipment modulate circuit schematic diagram shown in Fig. 5 is built to simulation model, can obtain the simulation result shown in Fig. 6.From simulation result, can see, this modulate circuit can steady operation.The output voltage U out of circuit can be stabilized in 3.1V left and right, the voltage of storage battery is also finally stabilized in 3.1V left and right, and input voltage Uin circuit when reaching 330mV can start work, circuit response time is very short, and input voltage Uin remain at circuit under lower magnitude of voltage just can steady operation.From simulation result, can see, when input energy in outside is comparatively sufficient, output circuit will be battery storage energy, the voltage at Ubat two ends also constantly slowly raises, when higher than 3.1V, will start as energy-storage battery charging, the output voltage U out of circuit is basicly stable, and in 3V left and right, the voltage regulation result of circuit is very obvious, can meet the electric energy conditioning requirement of energy collecting conversion.
