Abstract

The invention discloses a ground test system suitable for payload high-speed data acquisition and transmission, which is used for carrying out ground test on payload equipment based on a TLK2711 high-speed serial transmission chip and comprises an acquisition and transmission subsystem and a processing module deployed on an upper computer, the acquisition and transmission subsystem is used for setting an interface rate and a transmission protocol according to parameters configured by the processing module, receiving and caching analog data sent by the processing module, and sending the analog data to effective load equipment through a TLK2711 interface; the cache module is also used for receiving the load data, analyzing the cache and sending to the processing module; the processing module is used for performing parameter configuration on the acquisition and transmission subsystem according to the interface rate and the transmission protocol of the payload equipment, reading an analog data file, framing and sending the analog data file to the acquisition and transmission subsystem, and receiving and storing the load data cached by the acquisition and transmission subsystem; the system is also used for receiving the real-time state of the acquisition and transmission subsystem.

Description

technical field [0001] The invention relates to the technical field of high-speed data transmission, in particular to a ground test system suitable for high-speed data collection and transmission of payload. Background technique [0002] With the rapid development of space science and detection technology, the types and quantities of payloads will experience explosive growth. Some payloads have a large amount of data and have high requirements for data transmission. The development of parallel transmission technology is hindered by a series of problems such as difficult timing synchronization, serious signal offset, weak anti-interference ability and high design complexity. Compared with parallel transmission technology, serial transmission technology has fewer pins, strong scalability, point-to-point connection, and can provide higher bandwidth than parallel transmission, so it has been widely used in the field of embedded high-speed transmission. [0003] At present, the ...
