Serial bus communication system and communication method

Abstract

The invention discloses a serial bus communication system and a communication method. The communication method comprises the steps of: S1, a camera controller main FPGA and a camera controller standbyFPGA transmit signals to a camera distributor FPGA at the same time; S2, a data receiving and transmitting module of the camera distributor FPGA receives and identifies the two paths of signals, selects one path as a valid signal and transmits the valid signal to a data processing module of the camera distributor FPGA, and a left half focal plane processing FPGA and a right half focal plane processing FPGA of a CCD corresponding to the camera distributor FPGA; S3, the data processing module, the left half-focal-plane processing FPGA and the right half-focal-plane processing FPGA respectivelyprocess the received effective signals and transmit return signals to an AND logic module of the camera distributor FPGA; s4, the AND logic module performs AND logic on the received three paths of return signals and then transmits the signals to the data receiving and transmitting module; and S5, the data transceiving module returns the received return signal to the camera controller main FPGA orthe camera controller standby FPGA. The communication method can improve the working efficiency of the system, and can improve the reliability of the system.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a serial bus communication system and a communication method. Background technique [0002] The CCD camera is controlled by the CCD controller for imaging. The CCD controller is the key part of the CCD camera, which completes the drive of the CCD and the signal readout. The performance of the CCD controller directly determines the imaging performance of the CCD camera. At present, the communication architecture between the CCD controller and the CCD camera has the following two problems: [0003] 1. Only one-to-one control of the CCD controller to the CCD camera can be realized, and the one-to-many control of the CCD controller to the CCD camera cannot be realized, and the work efficiency needs to be improved; [0004] 2. The CCD controller does not have a redundant design. When the CCD controller fails, it will cause the CCD camera to be paralyzed and the reliability is n...
