Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is circuit diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Execution mode of the present utility model includes but not limited to the following example.
[embodiment]
Transducer electric supply installation as shown in Figure 1, it comprises solar cell S, the positive pole of described solar cell S is connected on the anode of diode D1, the minus earth of described solar cell S, the negative electrode of described diode D1 is connected to the ground by capacitor C, the negative electrode of described diode D1 is connected with the anode of diode D2 simultaneously, the negative electrode of described diode D2 is connected with the negative electrode of diode D3 and is connected on power supply simultaneously, the anodic bonding of described diode D3 on the positive pole of storage battery E, the minus earth of described storage battery E.In the utility model, in order to solve the problem of service life of battery, consider that two kinds of energy possess the mode for transducer power supply simultaneously.A kind of for storage battery is transducer power supply, another kind of in order to utilize solar cell for supplying power mode to power for transducer, which is directly employing not, but existing capacitor C stored charge mode stores, and power supply is provided in the time that transducer needs.Utilize the redundancy of two kinds of supply power modes, ensure the long-time use of transducer.Capacitor C, for stored charge, strengthens the charge capacity of whole electric supply installation.Diode D1 protects solar cell S, and in the time that the voltage of solar cell S is less than the conducting voltage of diode D1, diode D1 turn-offs, and avoids solar cell S over-discharge can.
In order to increase the reserve of electricity of capacitor C, described capacitor C is polar capacitor.Its capacitance of polar capacitor is larger, and its storable electric charge is many.
Described diode D1, diode D2 and diode D3 all adopt IN4148.IN4148 is cache switching diodes, and it is shorter than general diode that it becomes the needed time of cut-off from conducting.Adopt IN4148, can improve the reliability of power supply circuits.
In the present embodiment, as preferred embodiment, diode D1, diode D2 and diode D3 all adopt IN4148; Capacitor C 1 can adopt the electric capacity of 4F/5.5V.Through emulation, adopt the electronic device of above-mentioned specifications and models, it can make the performance of circuit reach optimum.
Be as mentioned above embodiment of the present utility model.The utility model is not limited to above-mentioned execution mode, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, within all falling into protection range of the present utility model.
