Abstract
The utility model discloses a solar mobile power supply with an intelligent monitoring load function, which comprises a load current detection circuit, an amplifier and a single-chip microcomputer with an analog/digital (A/D) conversion interface. The voltage signal output end of the load current detection circuit is connected with the input end of the amplifier, and the output end of the amplifier is connected with the A/D conversion interface of the single-chip microcomputer. The solar mobile power supply with the intelligent monitoring load function can effectively monitor load current so as to protect solar batteries, and is high in security.
Description
Technical field
The utility model relates to a kind of solar energy movable power supply with intelligent monitoring loading functional.
Background technology
When using portable power source, in case load break down, such as short circuit; Cause electric current suddenly to increase, not only can exhaust the electric weight on the portable power source very soon this moment, and cause portable power source to burn out easily; Even might be explosion caused, therefore be necessary existing portable power source is improved.
The utility model content
The technical problem to be solved of the utility model provides a kind of solar energy movable power supply with intelligent monitoring loading functional; This solar energy movable power supply ability effective monitoring load current with intelligent monitoring loading functional is with the protection solar cell, and is safe.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:
A kind of solar energy movable power supply with intelligent monitoring loading functional; The single-chip microcomputer that comprises load current detection circuit, amplifier and band A/D translation interface; The voltage signal output end of load current detection circuit connects amplifier input terminal, and the output of amplifier connects the A/D translation interface of single-chip microcomputer.
This solar energy movable power supply promptly passes through solar energy photovoltaic panel to battery charge through solar recharging.
Solar energy movable power supply with intelligent monitoring loading functional also comprises LED light, and LED light is connected with single machine output end.
The beneficial effect of the utility model:
The solar energy movable power supply with intelligent monitoring loading functional of the utility model; Be used for load (like mobile phone and other data products) is charged or stand-by power supply is provided, adopt the load detecting resistance detection also to monitor load current, after not having load or charging to accomplish; There is not electric current to pass through on the load detecting resistance; Then to detect corresponding voltage signal be zero to single-chip microcomputer, and a time (as one minute) shutdown automatically just is set automatically, also extinguishes the indicator light of machine simultaneously.Same when load is transshipped, but the flicker of Single-chip Controlling indicator light, and in time close portable power source, i.e. shutdown automatically, thus portable power source itself and load are all played a protective role.
Thereby, the utlity model has safe advantage.
Description of drawings
Fig. 1 is the structured flowchart with solar energy movable power supply of intelligent monitoring loading functional.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Embodiment 1:
As shown in Figure 1; A kind of solar energy movable power supply with intelligent monitoring loading functional; The single-chip microcomputer that comprises load current detection circuit, amplifier and band A/D translation interface; The voltage signal output end of load current detection circuit connects amplifier input terminal, and the output of amplifier connects the A/D translation interface of single-chip microcomputer.Solar energy movable power supply with intelligent monitoring loading functional also comprises LED light, and LED light is connected with single machine output end.
Current measuring element in the load current detection circuit is a resistance; This resistance string is connected in the electric current output loop of solar energy movable power supply; On the positive voltage output line of serial connection like solar energy movable power supply, detect this ohmically voltage and can obtain electric current (magnitude of voltage is designated as current value divided by resistance value).
