Embodiment Construction
[0016] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0017] as attached figure 1 As shown, the overall structure diagram of a large-scale programmable control target trajectory simulation device, which includes a controller module (1), a voice coil motor drive module (2), a two-axis motion table module (3), a stepping motor drive module Module (4), swing mirror module (5). The controller module collects the signal of the position sensor installed on the two-axis motion table module at a specified frequency through interruption, and then calculates and corrects the output driving signal through the control program. The driving signal consists of two parts: the driving signal of the voice coil motor and the driving signal of the stepper motor, and the deflection angles of the two actuators are corrected and controlled by using these two driving signals in turn. Both the voice coil...

The invention relates to a large range of programmable control stimulated device for target trajectory, in allusion to the problem that the current stimulated device for target trajectory fails to achieve system tracking and measuring demand from different elevations, wherein the stimulated device combines an oscillating mirror driven by stepping motor and trajectory stimulated device under drive of voice coil motor, target light from the trajectory stimulated device achieves target surface imaging after oscillating mirror reflection, in this way, pitching dynamic range of stimulated trajectory can be effectively improved. Through execution of control procedure by controller, target trajectory of different speeds and accelerated speeds can be achieved, which greatly improves trajectory stimulation flexibility. Oscillating mirror has small size, and light weight, thereby the device adding ensures features of small size, light weight and good portability for the original device, so that the device can be carried to the field for tracking and measuring, and improves practicability of trajectory stimulated device.
Description
technical field [0001] The invention belongs to the field of target trajectory simulation, and in particular relates to a large-scale programmable control target trajectory simulation device, which is used to simulate a large-scale movement trajectory of a target, and provides a more practical experimental verification test platform for photoelectric tracking equipment. Background technique [0002] In the debugging process of photoelectric tracking equipment, it is necessary to use the target trajectory simulation device to test the equipment repeatedly to test the accuracy and reliability of the tracking system. During the early testing process of the equipment, the equipment is generally in a closed debugging workshop or laboratory, and the traditional and widely used trajectory simulation device is the moving target. The moving target uses a rotating arm to drive a point light source to simulate a moving target, but it has the disadvantages of small dynamic range, poor f...
