Embodiment Construction

[0037] In order to facilitate the understanding of the embodiments of the present invention, several specific embodiments will be taken as examples for further explanation below in conjunction with the accompanying drawings, and each embodiment does not constitute a limitation to the embodiments of the present invention.

[0038] DSP (Digital Singnal Processor, digital signal processing) is a unique microprocessor, a device that processes a large amount of information with digital signals. Its working principle is to receive an analog signal, convert it into a digital signal of 0 or 1, then modify, delete, and strengthen the digital signal, and interpret the digital data back to analog data or the actual environment format in other system chips. Not only is it programmable, but its real-time running speed can reach tens of millions of complex instruction programs per second, far exceeding that of general-purpose microprocessors. It is an increasingly important computer chip in ...

Abstract

An embodiment of the present invention provides a portable power management device based on digital signal processing. The device mainly includes: a digital signal processing unit, a voltage sampling unit, a sampling interface unit and a display processing unit. The voltage sampling unit performs AD sampling processing on the voltage signal of the portable power supply, obtains the voltage value of the portable power supply, and transmits the voltage value of the portable power supply to Digital signal processing unit; the digital signal processing unit compares the voltage value of the portable power supply transmitted by the voltage sampling unit with the preset voltage threshold range, determines the voltage state information of the portable power supply according to the comparison result, and converts the voltage state information of the portable power supply to And the voltage value is transmitted to the display processing unit. The embodiments of the present invention control the charge and discharge of the battery as a whole through the DSP control chip and related voltage, current, and temperature sampling current, so as to ensure the safe use of portable power sources such as battery packs.

Description

technical field [0001] The present invention relates to the technical field of power management, in particular to a portable power management device based on DSP (digital signal processor, digital signal processing). Background technique [0002] With the development of instruments and meters, more test environments are not limited to the laboratory environment. Some instruments and equipment that need to be used outdoors need to be powered by a portable independent power supply to ensure normal operation. [0003] The application fields of lithium batteries are becoming more and more extensive. Various instruments and equipment are applied to the power supply of lithium batteries. Multiple lithium batteries are connected in series to form a lithium battery pack. For the management of lithium batteries, lithium battery packs and other batteries more and more important. At present, a variety of portable devices use portable power sources, such as lithium battery packs, to so...
