A spacecraft universal interface controller comprises a bus HOST interface processing unit, a UART interface processing unit, a TDM arbitration processing unit, an instruction parse processing unit, a time sequence parallel interface processing unit, non-time-sequence parallel interface processing unit, a serial data output interface processing unit, a serial data input interface processing unit, a serial data collection interface processing unit and a remote measuring status framing processing unit.The universal controller achieves protocol processing and time sequence control of a time sequence parallel interface, a non-time-sequence parallel interface, a serial data output interface, a serial data input interface and a serial data collection interface through a replaceable processer, data interaction and protocol processing among the interfaces such as a satellite-borne bus and a UARAT interface, the bus system structure of a traditional spacecraft comprehensive electronic computer, information interaction between the processor and the interfaces is simplified, and the overall performance of a spacecraft comprehensive electronic system.

Description

technical field [0001] The invention belongs to the technical field of spacecraft comprehensive electronics, and relates to an interface controller used on a spacecraft. Background technique [0002] The integrated electronic system is the center of spacecraft information processing, and has a large number of spacecraft communication interfaces with other subsystems of the spacecraft. [0003] In the traditional spacecraft electronic interface design, due to the difference in circuit design and software design, the operation timing and speed of the spacecraft communication interface are not exactly the same in different spacecraft. Most of these interfaces are non-standard custom interfaces. Causes problems such as special interface forms and various types, poor reliability, and multiple failure modes, which greatly limits the reliability, versatility, and reusability of spacecraft electronic components and hardware modules; at the same time, these interfaces are completely ...
