Example Embodiment

[0015] In order to describe in detail the technical content, structural features, achieved objectives and effects of the present invention, the following will be described in detail in conjunction with embodiments and accompanying drawings.

[0016] See figure 1 The general SpaceWire node device of the present invention includes a controller 1, a SpaceWire node device 2, a transmission data storage unit 3, and a crystal oscillator that provides clock pulses for the controller 1 and the SpaceWire node device 2. The controller 1 receives control instructions and a set of configuration instructions from the SpaceWire network. The control instructions include data receiving instructions and data sending instructions, and may also include the configuration instruction set. That is, the controller 1 can receive data from the SpaceWire network. The configuration instruction set can also accept the configuration instruction set from mature equipment (for example, the commonly used 422 int...

Abstract

The invention provides a general SpaceWire node device comprising a controller, a data cache unit, a SpaceWire node device and a transmission data storage unit. The controller receives data of a high-speed interface and transmits the data to the data cache unit. Then the data are read from the data cache unit to the transmission data storage unit. The SpaceWire node device sends the data in the transmission data storage unit to a SpaceWire network, and a sending state is returned to the controller. The controller also monitors the operation state of the SpaceWire node device, and the SpaceWire node device is configured according to the received configuration instruction set. Functions of communication and data interaction with the SpaceWire routing network can be completed so that matured products can be rapidly accessed to the SpaceWire network, and period and cost for developing new products can be reduced.

Description

technical field [0001] The invention relates to the SpaceWire bus technology for satellites, in particular to a general-purpose SpaceWire node device that can quickly expand mature loads, data processors, large-capacity storage and other products into SpaceWire node equipment. Background technique [0002] At present, the high-speed data processing systems that connect payloads, data processors, and large-capacity storage devices inside satellites mostly directly use LVDS technology for point-to-point transmission without introducing bus technology. However, as space missions become increasingly complex, a large amount of data exchange between different devices is required, which inevitably requires satellite internal communication to have higher processing speed, reliability and radiation resistance, as well as error detection and recovery capabilities. The system structure cannot meet this requirement. Developing a new technology that can meet the above requirements requi...
