Embodiment Construction
[0018] In conjunction with accompanying drawing, provide embodiment of the present invention as follows:
[0019] A data transmission bus conversion method, the steps are as follows: receiving telemetry parallel data (BMK) frame by (sub) frame, and converting the received parallel data into serial data; performing lossless compression processing on the serial data; The data is transmitted to the host computer through Ethernet; the host computer demodulates various physical variables according to the data transmission protocol and the product data telemetry protocol, records and stores them. Testers complete the tasks of remote setting of working status and query information interaction through the host computer.
[0020] Implement the data transfer bus conversion system of above-mentioned method, as Figure 1-4 Shown: The high-end architecture of FPGA+DSP+ARM is used as the real-time information processing platform, and Ethernet is used as the communication method with the up...
