Power management system and robot

Abstract

The invention relates to a power management system and a robot. A first DC conversion module generates an internal power supply according to a battery power source to provide power for each functionalmodule. A second DC conversion module generates a first external power supply and a second external power supply according to the battery power source and an enable signal. A third DC conversion module generates an algorithm processor power source and a reserved power source according to the battery power source and the enable signal. A detection module detects the first external power supply, the second external power supply, the algorithm processor power source, and the reserved power source to generate corresponding power detection signals. A conversion module generates wired communicationsignals according to the power detection signals. A control module generates enable signals according to the wired communication signals. Therefore, real-time monitoring and management of each powersupply is realized and ADC analog-to-digital conversion interface resources of the control module are saved. The power supplies and signals are separated, so that the hardware costs and research and development workload are reduced and the response speed and control accuracy of the power management system are improved.

Description

technical field [0001] The invention belongs to the technical field of robot power supplies, and in particular relates to a power supply management system and a robot. Background technique [0002] With the rise of the robot industry, more and more robots are appearing on the market. These robots are replacing human labor in various ways and reducing the labor burden for humans. As the core of the robot's power supply, the robot's power management system must be reliable and practical in terms of electrical safety, stability and reliability, and electromagnetic compatibility. [0003] In the current robot power management solutions on the market, the power management system is processed and controlled by a single-chip microcomputer after voltage or current sampling and analog-to-digital conversion. The system control accuracy is low and the response speed is slow, which may easily lead to overcurrent and other faults in the system and damage circuit elements. A situation oc...
