Problems solved by technology

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 register. For example, for 32-bit wide data, two 16-bit wide data can be used. The buffers jointly carry the 32-bit wide data transmitted by the CPCI computer, but if two or three channels of parallel data need to be transmitted, the existing single-channel data transmission adapter will not only not meet the needs of the system, but will also affect the operation of the computer. system impact

Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] The three-channel data transmission adapter in this embodiment, its electrical schematic diagram is as follows figure 1 As shown, it includes: data processing module A and transfer output module B.

[0027] Its connection relation is: the input end of data processing module A is connected with the output end of the first CPCI computer in the external device; The output end of data processing module A is connected with the input end of transfer output module B; The output end is connected with the input end of the second CPCI computer in the external device.

[0028] The first CPCI computer in the external device outputs data address multiplexing information and control signals to data processing module A; data processing module A separates data information and address information from the received data address multiplexing information; then data...

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 (Compact Peripheral Component Interconnect, Compact PCI) computers often use single-channel data transmission adapters, which can convert the data sent by the CPCI computer into synchronous data stream output, and at the same time It has the function of rate switching. 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 sel...
