Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments. Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
Refer to Fig. 1 ~ 2, a kind of based on monolithic processor controlled pocket lamp, including main control MCU, USB input module, charger input module, current control module, battery battery core, DC/DC module, super-charge super-discharge protection module, 5V output and Voltage Feedback interface, electricity quantity display module, voltage sample module, voltage amplification/comparison module, described main control MCU connects current control module respectively, DC/DC module, voltage sample module and electricity quantity display module, current control module connects USB input module respectively, charger input module, battery battery core and DC/DC module, battery battery core is also connected with super-charge super-discharge protection module, DC/DC module is also respectively connected with 5V output and Voltage Feedback interface and voltage amplification/comparison module, voltage sample module is also respectively connected with 5V output and Voltage Feedback interface and voltage amplification/comparison module.
Main control MCU is A8P1261A single-chip microcomputer. Electricity quantity display module is LCD indicator.
The operation principle of the present invention is: when the charger having USB voltage and 5V to input or to match accesses and inputs, input current voltage can be controlled after processing according to the data that namely battery real time electrical quantity situation is obtained by voltage sample by main control MCU, by constant current or constant voltage mode, battery battery core is charged, in order to avoid surpassing stream or superpressure and battery being caused damage. Also need to prevent over-charging of battery when charging, prevent that this crosses when electric discharge and put, therefore need to plus super-charge super-discharge protection circuit on battery charger. Need to in power supply or discharge process namely pocket lamp powered by battery battery core when portable power source, direct current DC/DC boost module is controlled in real time by master control by voltage sampling circuit and voltage amplification comparison circuit, and output 5V voltage is for external electric equipment use.
Native system is with A8P1261A single-chip microcomputer for control core, real-time sampling, sampled data carries out calculation process by single-chip microcomputer thus completing the measurement of current voltage and electric current, subsequently voltage is shown by LCD liquid crystal display screen, and the operation of the value control whole system according to current/voltage. System master program circuit such as Fig. 2.
