[Abstract]:With the rapid development of infrared and laser technology, infrared guided weapons are becoming more and more mature, and developing towards the direction of high real-time, high resolution and good controllability.As the main test and evaluation means of guidance weapon, the requirement of data and data transmission rate of infrared array hardware-in-the-loop simulation system is also increasing, aiming at the shortcoming of the existing hardware-in-the-loop simulation system's poor real-time performance.In this paper, the optical fiber high-speed transmission system is designed and applied in the simulation of infrared array. The system adopts the self-designed optical fiber communication protocol, and gets rid of the dependence of the original system on the reflective memory card. The system is more reasonable in structure and has fast transmission speed.Because of its strong portability, it can guarantee the real-time performance of infrared array hardware-in-the-loop simulation system.The main contents of this paper are as follows: firstly, the topology and stack structure of fiber channel protocol, which is widely used in the field of optical fiber network communication, is studied, and the optical fiber communication protocol suitable for digital communication system is proposed.Based on the analysis of the existing system scheme, an infrared array hardware-in-the-loop simulation optical fiber high-speed transmission system based on the self-designed optical fiber communication protocol is constructed, and the bus mechanism is analyzed.The implementation technology of optical fiber communication and the performance of the main controller are studied and analyzed, which provides the necessary guarantee and guidance for the functional design of each part of the system.Secondly, the hardware architecture of the hardware-in-the-loop simulation fiber-optic high-speed transmission system with infrared array is planned, and the hardware of each part is analyzed and designed, and the bus interface unit, serial / series-parallel conversion unit, optical transceiver module unit are established.Based on the theory of signal integrity, the cabling technology of high speed transmission system is studied, which provides the guarantee for the realization of the hardware function of the system.Then, the key technologies in logic design, such as cross clock domain and timing optimization, are studied, and then the whole architecture of optical fiber communication protocol IP(Intellectual property core is constructed, and the bus control module and buffer module in IP core are analyzed.The module of sending and receiving control is analyzed and designed, and the function of each module is simulated. The results show that each module can work normally.Finally, the system test platform is built, and the upper computer software and driver are written to test the bus interface and the optical fiber communication function respectively, to ensure that they can work normally, and then to carry out the comprehensive test of the system.The performance of the system is evaluated by embedded logic analyzer. The results show that the infrared array hardware-in-the-loop simulation optical fiber transmission system designed in this paper can achieve a very high transmission rate and can meet the requirements of the project.
