AI Technical Summary
Technical Problem
Due to the excessive number of cables connected to the hard disk backplane, the cost of signal transmission is high.
Method used
The VPP lighting signal and SGPIO lighting signal are scheduled and switched in an orderly manner using the preset time-division multiplexing method, and the two signals are transmitted to the logic device of the hard disk backplane through the same light cable.
Benefits of technology
The number of cables connected to the hard disk backplane is reduced, the timely and accurate signal transmission is ensured, the cost of signal transmission is reduced, and the accuracy of signal transmission is improved.

Abstract
Embodiments of the present application provide a signal transmission system and method. The system comprises: a server motherboard, and a hard disk backplane provided with a target logic device and a set of hard disk slots, wherein the server motherboard is configured to: obtain a VPP lighting signal and an SGPIO lighting signal; and use a preset time division multiplexing mode to schedule and switch the VPP lighting signal and the SGPIO lighting signal in a time-sharing ordered manner, so as to transmit the VPP lighting signal and the SGPIO lighting signal to the target logic device by means of the same lighting cable, wherein the preset time division multiplexing mode is continuously detecting the VPP lighting signal and the SGPIO lighting signal within a time division multiplexing period, performing identification and judgement on the basis of respective waveform characteristics, sampling the continuously sent VPP lighting signal and SGPIO lighting signal, and on the basis of specific flag bits of the signals and a preset specific rule, alternately switching the VPP lighting signal and the SGPIO lighting signal to a time division multiplexing channel.
