Embodiment Construction
[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.
[0024] In order to form a control network, the present invention realizes the control of multiple CCD cameras by one camera controller. The camera controller communicates serially with each CCD camera in a point-to-point manner to control the CCD cameras.
[0025] More specifically, each CCD camera includes a distributor FPGA and a CCD focal plane processing board, and the CCD focal plane processing board includes a left half focal plane processing FPGA and a right half focal plane processing FPGA, and a camera controller FPGA and each CCD camera The power distribution FPGA of each CCD...

The invention discloses a serial bus communication system and a communication method, wherein the method includes: S1, the main FPGA of the camera controller and the backup FPGA of the camera controller simultaneously send signals to the FPGA of the camera distributor; S2, the data sending and receiving of the FPGA of the camera distributor The module receives and identifies two signals, and selects one as an effective signal to send to the data processing module of the camera distributor FPGA, the left half focal plane processing FPGA and the right half focal plane processing FPGA of the 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 respectively process the received effective signals, and send the return signal to the AND logic module of the camera distributor FPGA; S4, and the logic module will receive The received three-way return signals are taken and logically sent to the data transceiver module; S5, the data transceiver module returns the received return signals to the main FPGA of the camera controller or the backup FPGA of the camera controller. The invention can not only improve the working efficiency of the system but also 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...
