Military electric visual angle adjusting display and control device

Abstract

The invention relates to a military electric visual angle adjusting display and control device. The device comprises a device cabinet, a workbench and an overturn component, the overturn component ismovably hinged to the device cabinet, and a linear motor, a telescopic pushing arm, pneumatic spring pushing rods and a controller are arranged in the machine cabinet; the fixed end of the telescopicpushing arm is installed on the linear motor, and the other end of the telescopic pushing arm is connected with the overturn component; controllability of the overturn component is good in electric and pneumatic combined motions, the performance is reliable, the safety degree is high, a push rod of the linear motor is high in self-locking performance, and the device is suitable for overturning motion control occasions of components which are high in safety and controllability requirements and large in mass and bear vibration impacting and loading in the hovering state. The military electric visual angle adjusting display and control device is assembled in a naval ship of the China, stepless adjustment of the visual angle between 0 degree-15 degrees is achieved, and the device can hover atany position and resist the influence of bad conditions on the naval ship, is used for more than one year, and has no faults.

Description

technical field [0001] The invention belongs to the field of electromechanical control, and relates to the technology of video display and control devices, in particular to a display and control device for electric adjustment of military angle of view. Background technique [0002] Due to the significant cost reduction of the linear motor push rod, simple stroke control, and its own protection function, it is more and more widely used in the drive system of moving parts. At present, with the rapid development of linear motors and control technology, the existing linear motors are becoming smaller and lighter in size, lighter in weight, simpler in control system, and more complete in function. [0003] At present, there are also military products in China that use linear motors to realize the flipping and moving of moving parts. However, due to the heavy weight of moving parts, or the use of high-power linear motors, the equipment is bulky; or it is driven by dual linear moto...

Problems solved by technology

[0003] At present, there are also military products in China that use linear motors to realize the flipping and moving of moving parts. However, due to the heavy weight of moving parts, or the use of high-power linear motors, the equipment is bulky; or it is driven by dual linear motors, which will cause linear motors. If the pace is inconsistent, it is necessary to establish a feedback loop between the axes of the dual motors, and use a special PID control method to prevent the motion of the linear motors from being out of sync. This will cause complex equipment configuration, increase costs, and increase failure points.
