Abstract

The invention relates to a three-channel data transmission adapter. The three-channel data transmission adapter comprises a data processing module A and a switch-over output module B, wherein the data processing module A comprises a CPCI computer interface (1), a CPCI I / O accelerator (2), a data transmission control module (3), a first buffer (4), a second buffer (5), a third buffer (6), an interface conversion output module (7), a power module (8), a crystal oscillator (9) and a parameter configuration module (10). According to the three-channel data transmission adapter, the buffers with sixteen bit wide are used for carrying out caching on parallel data of thirty-two bits, different data of three paths can be transmitted, and the rate of a transmission code can be changed.

Description

technical field

[0001] The invention relates to a three-channel data transmission adapter, which is suitable for data interaction with a CPCI computer in systems such as unmanned aerial vehicle measurement and control and air-ground image data transmission that have special requirements for system compatibility, system anti-interference, and ambient temperature. Communication measurement and control, information transmission field. Background technique

[0002] At present, domestic data transmission adapters used to interact with CPCI (CompactPeripheral Component Interconnect, Compact PCI) computers often use single-channel data transmission adapters, which can convert data sent by CPCI computers into synchronous data stream output, and at the same time have rate switching function. However, a CPCI computer slot can only send out one channel of data, and due to the requirements of printed board wiring, there are also restrictions on the bit width of the selected data regist...
