Embodiment Construction

[0035] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0036] The technical scheme adopted in the present invention is divided into two parts: the circuit part and the mechanical part;

[0037] 1. The circuit part of this solution is based on MCU microcontroller technology, including 32-bit MCU controller module, 6S ​​lithium battery pack, relay switch, DC-DC transformer module, RS422 interface, voltage comparator, full bridge rectifier module, voltage detection Modules, voltage conversion modules, travel switches, solenoid drivers, electromagnets, etc.

[0038]The function completed by this part is to realize the control and status output of the whole power system. The following is an introduction to the function of each component in the circuit. The function of the full-bridge rectifier module is to obtain a unidirectional DC voltage when the battery is connected in any way under the condition that the physical c...

Abstract

The invention relates to a small satellite replaceable power supply system. An MCU microcontroller module is used for collecting the voltage of each point of a power supply management module. An MCU is provided with an UART and other interfaces, and is easy to develop and debug. Meanwhile, the MCU is provided with abundant general I / O ports, so that the relay control can be conveniently realized,wherein PWM control signals are provided. According to the technical scheme of the invention, the mechanical interface mode of a 6S battery pack and a power supply management module is provided. Whena battery needs to be arranged, an active guidance goes ahead. When the battery needs to be taken out, the active guidance pops up. According to the invention, based on the MCU micro-controller technology, the system is high in integration degree and small in size. The power management program in the MCU can be customized according to needs, so that the system is short in development period and easy to upgrade. The system can be applied to power supplies required by various loads on a small satellite electronic system, wherein the operations of on-orbit replacement, forward and reverse insertion operation and repeated usage can be realized. The system enters a sleep mode under the condition that a power supply is not needed. Therefore, the power loss of the power supply is reduced.

Description

technical field [0001] The invention relates to a replaceable power supply system for small satellites, in particular to a replaceable, reusable and easy-to-manage power supply that can actively guide the power supply to be plugged and unplugged, supports forward and reverse plugging operations, and is applied to a small satellite electronic system. system. Background technique [0002] With the development of space technology and the increasing frequency of human space exploration activities, the number of satellites in space is increasing exponentially, and the functions of satellites also need to be upgraded. Especially when it comes to its electronic systems, there is a high demand for upgrades. The overall design idea is adopted in the traditional satellite design, and its electronic system is only considered for one-time use. With the rapid development of aerospace technology, spacecraft in-orbit service technology has emerged. The proposal of on-orbit service techn...
