Integral Technical Scheme of Payloads System for Chinese Mars-1 Exploration
-
摘要:
简要介绍了中国首次火星探测工程的科学目标与有效载荷的配置,有效载荷分系统的总体技术方案,包括有效载荷供配电、遥测遥控、科学数据处理、在轨自主运控,以及有效载荷分系统在轨基本工作流程安排。针对火星环绕器有效载荷功能复杂、安装位置分散等特点,配置了独立的载荷控制器设备,通过总线网络将有效载荷分系统组成有机整体,实现与环绕器平台的统一电接口。针对火星车有效载荷在重量、体积、能源等方面的严格限制,通过最大限度地将各有效载荷主控电子学控制单元集成于一台载荷控制器设备中,实现了对有效载荷的集中控制和管理。
Abstract:Science objectives and payloads configuration for Chinese Mars-1 exploration project are introduced. Integral technical scheme of the payloads system are introduced, including the power supply, telecontrol and telemetry, science data processing, onboard autonomous, and the major program of workflow. According to the complex functions and decentralized placement of the Mars-1 orbiter payloads system, a dedicated payload-controller is designed to organically link the system through bus network, providing a unitive electrical interface with the orbiter platform. According to the restriction on the weight, volume and power supply of the Mars-1 rover payloads system, a public payload-controller is designed, integrating most of the main control units of the rover payloads, and realizing centralized control and management.
