The energy storage device includes: capacitor, inductance, energy storage chemical material and energy storage mechanical device in embodiments of the present invention One or more of.It, will be mainly with the shape of capacitor in subsequent embodiment of the present invention and its attached drawing for the simplicity described Energy storage device is presented in formula, and still, this is not the restriction to energy storage device type used in the present invention program.
In conjunction with the embodiment of the present invention, the external force twice for triggering the intermittent electric energy is acted, and has given a kind of target The description of state, specifically includes:
Interval time section of the power generator between the movement of external force twice meets the following conditions: acting in the external force of rear execution When being triggered, the potential difference of the output end of the power generator is less than preset threshold.Wherein, it is described set preset threshold as 10%-30%.It is the scheme for design and implementation that the potential difference, which is less than preset threshold, in embodiments of the present invention preferably Desired electrical potential difference is zero, i.e., just the previous power generation process of power generator produce electricl energy all conversion to electric storage device, just carry out down The power generation process of one wheel.Dbjective state herein is in order to which the Optimum Matching for reaching external force movement and spontaneous electric process is target , it is contemplated that if the generating dutation interval of external force action triggers is too short, it will result in last round of power generator electric energy and do not have also It is released effectively to energy storage device, the external force movement of next round just produces；Since the external force movement for being added to power generator is usual Be can not bring on power generator generated energy it is cumulative (also have exception, such as rotary-type power generator, as shown in Figure 4 (its wrap The transmission device of generating body and multiple gears composition containing soft magnetic bodies, permanent magnet and coil composition), the movement of continuous external force can be with The revolving speed of runner is improved, to generate the cumulative effect of generated energy size), in particular for the power generator of piece-picking type, such as Fig. 5 Shown (it includes the resetting apparatuses of the generating body of soft magnetic bodies, permanent magnet and coil composition and reset spring composition), it is continuous short The external force at interval acts, and only will increase the time that corresponding power generator persistently generates electricity, this carrys out the storage process of electric storage device It says, cost performance does not have the height of the above-mentioned dbjective state of the embodiment of the present invention.Therefore, dbjective state set forth above is suitable for for example dialling The power generator of piece, spring-piece type.
It is emphasized that the scheme that the embodiment of the present invention 1 is proposed, for the power generator of above-mentioned plectrum, spring-piece type (being also known as the power generator of homing position type in embodiments of the present invention) and above-mentioned rotary-type power generator are applicable in.
At least two connection types based on detection device described in the embodiment of the present invention 1, and in description scheme The detection logical concept introduced in the process, here, provide at least three kinds of modes for above-mentioned connection type and detection logic it Between implementation give specific elaboration, include: as follows
Mode one,
When one end of the detection device is connected with power generator, the detection logic is specially to detect power generation dress Set the output for completing predetermined number of times energy.Which is suitable under the movement of single external force, and electric energy caused by power generator can The scene of calibration.
As shown in fig. 6, being the waveform that power generator repeatedly acts, lower part is stored up after using control method of the present invention The energy waveform of energy device.L1 illustrates the energy of energy storage device when power generator generates electricity under external force action triggers in the figure Variation track, energy flows to processing unit at this time, and processing unit is started to work, and completes necessary preparation, and begin listening for The testing result of detection device, at this time processing unit work are stored up in operating mode 1 (as shown in the L2 section in Fig. 6) in the L2 stage Can the energy of device decline very slow, one-off arrives instantly, and the energy of energy storage device further increases, processing unit this When still be in operating mode 1 wait detection device trigger signal, until n-th external force act arrive (PP1 point) first can Amount continues to assemble in the storage device, since detection arrangement monitors are to current movement, triggers processing unit, processing unit is true Surely after having got specified trigger signal quantity, execute highly energy-consuming task into operating mode 2, just after PP1 soon just into The L3 stage is entered, the speed of the energy decline relative mode 1 in energy storage device is fast at this time, at this time the energy of the aggregation of energy storage device It has been enough that processing unit is supported to complete assigned tasks.
A kind of application scenarios of which one can be for realizing self power generation electronic organ, i.e., power generator be one or Multiple spontaneous electric appliances corresponding to piano case, due to support the persistent signal between the player of distal end to connect, being used for will The key information to play the piano is sent to the distal end player, consecutively presses n times Do key at this point it is possible to be set in, can meet Incipient stability signal between source player is connect, at this point, the mode of playing (i.e. mode 2), Yong Huchi can be transformed into The continuous process of playing be for maintaining original state after, it is lasting play mode needed for electric energy.
