FPGA remote online debugging method, device and system based on optical fiber communication

Abstract

The invention discloses an FPGA remote online debugging method, device and system based on optical fiber communication. The method comprises the steps of: S1, building an FPGA remote online debuggingsystem based on optical fiber communication, wherein the system comprises an antenna housing provided with an interface conversion circuit, an interface converter, and a debugging computer; the antenna housing provided with the interface conversion circuit is connected with the interface converter through an optical fiber, and the interface converter is connected with the debugging computer. The invention provides an effective means for remote debugging of a secondary radar system, solves the problems of long-distance transmission of online debugging signals and easy interference of the signals in the working period of a secondary radar, solves the problem that the number of signal channels of a mechanical scanning radar rotating joint is limited, solves the problem that the personal safety of maintenance personnel cannot be guaranteed in the maintenance period, debugging / maintenance work can be carried out anytime and anywhere, and safety, high efficiency, simplicity, convenience andthe like are realized.

Description

technical field [0001] The present invention relates to the technical field of radar system online debugging, and more specifically, relates to an FPGA remote online debugging method, device and system based on optical fiber communication. Background technique [0002] The conventional online debugging method is that the maintenance personnel connect the maintenance computer and the FPGA through an emulator to carry out online debugging at a place close to the equipment. [0003] Part of the signal processing of the secondary radar needs to be close to the antenna unit, and due to antenna erection requirements and personal safety reasons, once the erection is completed, personnel cannot climb onto the turntable at will. [0004] The antenna of the radar is set up high, which is not suitable for personnel to stay for a long time. Maintenance personnel usually concentrate on debugging, and may forget the danger of their own environment and cause safety accidents; it is necessa...
