specific Embodiment approach 1

[0019] Specific implementation mode one: refer to figure 1 and figure 2 Specifically explain this implementation mode. In this implementation mode, the 4-channel high-speed data output by the satellite data transmission unit is converted into an interface in the Cortex HDR protocol format to realize the expected function. Specifically, it is implemented according to the following steps:

[0020] Step 1. Use a high-performance programmable system-on-chip to receive multi-channel customized interface protocol data.

[0021] First, by designing the external interface hardware circuit, the LVDS differential signal is converted into a single-ended data signal that meets the requirements of the processor input signal. In order to ensure the safety of the satellite test, the interface circuit adopts a completely isolated design from the inside of the transfer module; after that, use The programmable logic resources (PL part) in the high-performance ZYNQ UltraScale+MPSoC design a cu...

Abstract

The invention discloses a multichannel high-speed data interface conversion module of a customized data transmission protocol, and relates to the satellite ground testing technology field. In order tosolve the problem that in the prior art, customized high-speed parallel interface data information is difficult to obtain in the satellite testing process, the method comprises the steps that 1, a high-performance programmable system-on-chip is adopted for achieving multichannel customized interface protocol data receiving; 2, interface data carrying; 3, data storage and format encapsulation; 4,a lightweight Ethernet protocol stack is transplanted and modified; and 5, data transmission based on the lightweight Ethernet protocol stack. The method has the advantages that the interface protocolis customizable, the data transmission speed is increased by 30%, the number of accessible channels is large, and the like, and high-speed LVDS interface signals can be collected in a specified protocol format and converted into standard Ethernet protocol data to be output to a client.

Description

technical field [0001] The invention relates to the technical field of satellite ground testing, in particular to a multi-channel high-speed data interface conversion module. Background technique [0002] Satellite ground testing is a key link to ensure the normal operation of satellites. The processing module that converts the dedicated satellite interface data format into the common Ethernet interface data format of ground equipment is the key to achieve controllable process, visible results, and comparable information. With the diversification and customization of satellite missions, more and more data needs to be transmitted between different stand-alone machines, and the interfaces between them are mostly high-speed LVDS parallel signals with personalized data protocols. Although LVDS signals have high transmission speed, Low power consumption, strong anti-interference ability, etc., but in the functional test and verification stage, it is difficult to obtain the data c...
