Space internal bus power distribution controller

Abstract

The invention provides a space internal bus power distribution controller and relates to the field of power supply control over satellite-borne equipment on a satellite. The problems that an existing space power distribution controller occupies hardware resources of a lower computer, the calculation difficulty and the complexity are improved, and circuits are complex are solved. The controller comprises a lower computer circuit, a shunting circuit, a charging control circuit, a discharging control circuit, a battery equalization circuit, a power distribution circuit and a sampling circuit which are used for data communication and instruction transmission through a 1-wire bus. A plurality of circuits are designed, reasonable distribution is carried out on power distribution, the stability and reliability of the power distribution controller are considered from multiple perspectives, various states occurring in power distribution are comprehensively analyzed, and real-time data monitoring ensures normal operation of equipment; meanwhile, the 1-wire bus design is used, and all data transmission is achieved through the bus, so that software and hardware functions of the power distribution controller are clear, the circuit structure is simplified, the error risk of the circuits is reduced, and the reliability of the power distribution controller is guaranteed on a mechanical layer.

Description

technical field [0001] The invention relates to the field of power supply control for on-board equipment on satellites, in particular to a space single internal bus power distribution controller. Background technique [0002] In the circuit design of the current satellite and other space power distribution controllers, each functional circuit needs to occupy a large amount of hardware resources of the lower computer, and more logic control is introduced from data telemetry to command control, which increases the difficulty of logic calculation and Increased software complexity. At the same time, the control data flow and telemetry data flow of each circuit will eventually be collected to the lower computer. Each circuit has its own modularity and independence. In the data collection, it is required to fully consider the mechanical structure of the hardware circuit design. Currently, space power distribution Due to the many and complex circuits of the electric controller, th...
