Design of real-time control software for laser target simulation system based on RTX64

  • In order to satisfy the time and position accuracy requirements of the simulated target point for the laser spot target dome projection system which takes the high-precision two-axis mechanical turret with a planar mirror as the core, a design scheme of computerized control software that running in RTX64 real-time extended system environment with high real-time and time accuracy. This design scheme combines the real-time controller area network (CAN) bus with Ethernet to realize data communication and cooperative control among subsystems. Meanwhile, the position accuracy and the time accuracy of moving target simulation are effectively improved. Keep the clock synchronization period 20 ms, in the experiment, the maximum errors of the simulated target point are 0.005 34° and 0.004 04°, respectively. The errors meet the simulation precision requirement of the laser point target spherical screen projection system, which proves that the design scheme of the real-time control software is feasible.
