Inclined output forbidding keyboard and implementation method thereof

Abstract

The invention discloses and provides an inclined output forbidding keyboard and an implementation method thereof. The keyboard can quickly lock keys and prevent data output in an inclined state, manual operation is not needed, and the implementation method of the inclined output forbidding keyboard is simple, effective, low in misjudgment rate and high in operation speed. The system comprises a processor, a keyboard matrix, a keyboard scanning interface, an information storage unit and an interface output module, the keyboard matrix is in electric signal connection with the keyboard scanning interface; the keyboard scanning interface, the information storage unit and the interface output module are in electric signal connection with the processor; the inclined output forbidding keyboard further comprises an inclination angle sensor electrically connected with the processor, the processor judges an angle signal transmitted by the inclination angle sensor, and when the processor detectsthat the inclination angle of the keyboard exceeds a set initial angle, the processor forbids data from being output from the interface output module. The keyboard is applied to the technical field of ship keyboards.

Description

technical field [0001] The present invention relates to a keyboard, in particular to a keyboard with tilt output prohibition and its realization method. Background technique [0002] A computer is a modern electronic computing machine used for high-speed calculations. The application of computers in modern ship systems is a current trend. As a commonly used external device for computers, keyboards are also widely used in various types of ships. The keyboards currently on the market cannot effectively prevent crises from occurring in emergencies. For example, when there is a strong wind and waves, the shaking and tilting of the ship will be severe, and the keyboard will often automatically send codes. Risk of crisis due to unstable standing or falling of objects around the keyboard and triggering the keyboard by mistake. [0003] In order to solve the problem of spontaneous code or false triggering of the keyboard on the ship due to the shaking and tilting of the ship, the ...

Problems solved by technology

The keyboards currently on the market cannot effectively prevent crises from occurring in emergencies. For example, when there is a strong wind and waves, the ship will shake and tilt severely, and the keyboard will often automatically send codes. The risk of a crisis due to unsteady standing or falling objects around the keyboard and triggering the keyboard by mistake

[0003] In order to solve the problem of spontaneous code or false triggering of the keyboard on the ship due to the shaking and tilting of the ship, the method currently used by the keyboard is to increase the stiffness coefficient of the return spring, which will cause the keyboard to be operated hard. Difficult to maneuver in an emergency

In addition, there are currently keyboards that lock keys through hotkeys, which can prevent spontaneous codes or false triggers after pressing the hotkeys, but it is difficult to quickly and accurately press the hotkeys in an emergency, and the operator needs to check all the keys. Only by constantly making judgments in the environment can we judge whether to press the hot key, the judgment accuracy is poor, the key locking speed is slow, and it is very inconvenient to use
