Design Of Power Supply System On Desert Robot

Through the desert robot getting into the desert hinterland to collect and analyze the information of the desert, making people understand the real-time state of desert environment, which provides important data in reducing the speed of the deserts spread and the sandstorm frequency.In order to provide the desert robot stable power, improve the utilization rate of the power supply, to make the robot work continuous and stable in the desert hinterland, the power supply system of the desert robot is designed. The robot power supply system designed in this paper is based on the conversion efficiency of LM2596 series and LM2678 series chips that used in the switching power as the control core, and the power supply system is managed intelligently by C8051F020, to improve the utilization rate of the power supply. The power supply system designed for the desert robot mainly provide power to the sand wheel drive system, the battery plate driving system, data acquisition module, an electromagnetic lock, temperature control module and communication system. Through the reasonable choice of components and the optimization design of power supply circuit, the power supply system can be efficient and reasonable supply power for the power need parts of the robot.Firstly, the topological structure and technical parameters of the power supply system is confirmed according to the systems composition of robot, and the corresponding parameter of the power consumer and the power supply system is calculated as well as their component selection. Then according to the requirement of voltage and power of the power consumer, the overall design scheme of the robot power supply system is confirmed, that including the design of hardware circuit and software design of the power supply system. Finally, the main performance index of the power supply system is tested, and the test results are analyzed.It shows that the main performance indexes such as the supply voltage, current, voltage regulation factor, load regulation, as well as the output voltage ripple all meet the design requirements, through the experiments and tests of the desert robot power supply system. And the desert robot power supply system designed in this paper has been applied in practical projects.
