Abstract

The invention discloses a pico-satellite-borne power supply system based on a low-power MCU. The pico-satellite-borne power supply system based on the low-power MCU is used for solving the technical problem that an existing pico-satellite-borne power supply system is poor in reliability. The technical scheme is that a battery managing unit, a DC-DC boosting module, an LDO voltage stabilizer, an LDO voltage-reducing module and the low-power MCU are added. Protecting a storage battery against excessive charging, excessive discharging and overheat is integrated on the battery managing unit which comprehensively monitors and adjusts discharging and charging of the storage battery. A signal collecting unit and an order actuating unit are integrated on the low-power MCU unit. The low-power MCU unit is used for monitoring and controlling the whole power supply system, can boost intelligent management of the power supply system, improve the utilization efficiency of energy and therefore, improve the reliability of the whole power supply system.

Description

technical field [0001] The invention relates to a pico-satellite on-board power supply system, in particular to a pico-satellite on-board power supply system based on a low-power consumption MCU. Background technique [0002] refer to figure 1 . The well-known pico-satellite is a new concept of kilogram-level satellite, which is based on high-tech technologies such as micro-nano technology and micro-electromechanical systems, and has outstanding advantages such as simplified design, small size, light weight, low development cost, and short launch cycle; Picosatellite consists of measurement and control system, attitude control system, star management system and integrated electronic system. The integrated electronic system includes a power supply system and an on-board computer. The power supply system is a key subsystem of a pico-satellite. It is responsible for the important task of supplying power to other subsystems and payloads. Improving the efficiency and reliabili...
