Optical fiber sensing technology-based operating rod

Abstract

The invention discloses an optical fiber sensing technology-based operating rod, which comprises an operating rod main body, a base, a rotating shaft, a spring A and a spring base, wherein the spring A is sleeved on the operating rod main body, the spring base is arranged below the spring A, the base is arranged below the spring base, the rotating shaft is arranged on the base, the rotating shaft is provided with an opening which passes through the rotating shaft vertically, the operating rod main body can extend out from the opening of the rotating shaft, an extent end of the operating rod main body is provided with a movable plate, a shell is arranged below the base, the movable plate is arranged inside the shell, a fixed plate is fixed on the inner wall of the shell, and a curved bracket is arranged between the fixed plate and the movable plate; a plurality of first A-side deformation teeth and a plurality of first B-side deformation teeth are distributed on the curved bracket, and a curved passage for a first signal optical fiber to pass through is formed between the head parts of every adjacent first A-side deformation tooth and the first B-side deformation tooth; and the first signal optical fiber is connected with a test unit, and the test unit is connected with a processing unit. The optical fiber sensing technology-based operating rod has a simple structure and reasonable design, is convenient to process and produce and has low cost.

Description

technical field [0001] The invention relates to a joystick, in particular to a joystick based on optical fiber sensing technology. Background technique [0002] The basic principle of the joystick is to convert the movement of the rocker controlled by the hand into electronic information that the computer can process. Joysticks are used in a variety of mechanical devices, including modern jet fighters, excavators, industrial controls, remote and radio controls, radar and navigation systems, robots and manipulators, measurement systems, medical devices and wheelchairs, to name a few. The different joystick technologies differ primarily in how much information they transmit. [0003] The simplest joystick is the one found in early microcomputer game consoles, which is nothing more than a special electronic switch. Its basic structure consists of a joystick resting on a plastic base with a resilient rubber casing. There is a circuit board in the base just below the joystick....

Problems solved by technology

Of course, such a joystick cannot satisfy people's needs, so the joystick technology is also constantly developing, and there are various types such as capacitive, inductive, electromagnetic, and photoelectric. Chinese patent application number 200710000210.0 "magnetic field Inductive Joystick" discloses a joystick based on magnetic induction. Although the structure is exquisite and practical, it is similar to other joysticks and still transmits information based on the transmission form of electrical signals. This will cause problems in strong electromagnetic interference or strong radiation environments. Subject to greater interference, such as in nuclear power plants, power plants, substations and other places, the use is restricted
