Air defense missile simulator video test signal synthesis device

Abstract

The invention discloses an air defense missile simulator video test signal synthesis device which is composed of a video signal generation module and a power supply module, wherein the video signal generation module is used for generating a video signal and inputting the signal to a video input end of a display so as to detect whether the display is good or not, and the power supply module is usedfor supplying power to the video signal generation module. The video signal generation module comprises two single-chip microcomputers, an adder electrically connected with the video signal output ends of the two single-chip microcomputers, and a reverse amplifier electrically connected with the adder. The two single-chip microcomputers are composed of a first single-chip microcomputer used for generating synchronizing signals and grid image signals and a second single-chip microcomputer used for receiving the synchronizing signals output by the first single-chip microcomputer, keeping synchronization with the first single-chip microcomputer and outputting highlighted display circle signals at the same time. The air defense missile simulator video test signal synthesis device is simple instructure, easy to supply power, good in stability, convenient to carry and suitable for being used under the field operation condition.

Description

technical field [0001] The invention relates to a video signal generator, in particular to a video test signal synthesis device for an air defense missile simulator, and belongs to the technical field of video signal synthesis. Background technique [0002] The portable air defense missile simulator system is a new type of air defense missile weapon simulation system developed by our country. Maintaining its good combat simulation performance is an important aspect to ensure the full play of our army's air defense missile combat effectiveness. The display part of the portable air defense missile simulator system is composed of a shooter monitor and three projections. A unified standard adjustment signal is required for simulation training. At the same time, a standard video adjustment signal is also required for inspection and splicing of the three projection videos. By inputting a standard video signal and observing the display of the monitor, you can judge the imaging perf...

Problems solved by technology

However, there are several problems in the detection, maintenance and adjustment of the display system at this stage: (1) The detection method is too simple, only by turning off the power, looking at the indicator light, adjusting the contrast, brightness and other methods to detect, cannot correctly reflect the fault (2) The display and measurement equipment is relatively large, which is not convenient for use under field conditions; (3) Under field conditions, it is difficult to find a standard video signal for functional testing of the monitor; Monitors for Coordinated Calibration
