Flame-proof type touch keyboard for mine

Abstract

The invention relates to a flameproof touch keyboard for mining, which includes a flameproof box body, glass is fixedly embedded in the upper part of the flameproof box body, and a plurality of metal touch keys and an insulating cushion film are arranged at the lower end of the glass. The insulating cushion film fixes a plurality of metal touch keys and is close to the lower end of the glass, and the flameproof box is provided with a static capacitance circuit board, and the static capacitance circuit board and the plurality of metal touch keys Connected by wires; a plurality of metal touch keys are used to sense the touch of the glass to generate corresponding sensing signals; the electrostatic capacitive circuit board is used to analyze and calculate the sensing signals to generate corresponding control signals , and send the control signal to the host computer, and the host computer performs corresponding control. Compared with the prior art, the invention is waterproof, oil-proof, explosion-proof, high in sensitivity, high in safety and convenient to carry.

Description

technical field [0001] The invention relates to the technical field of keyboards, in particular to a mine flameproof touch keyboard. Background technique [0002] The keyboard is the most commonly used and the most important input device. Through the keyboard, English letters, numbers, punctuation marks, etc. can be input into the external device, so as to send input signals to the external device. At present, there are mainly two types of keyboards used in mine operations: one is a mechanical keyboard; the other is a capacitive-sensing keyboard. Due to the problems of high noise, easy wear, and low service life, mechanical keyboards are gradually losing market availability due to their poor water resistance, dust resistance, and oil resistance. At present, the capacitive-sensing keyboard under the mine is better than the mechanical keyboard. Although it makes up for the shortcomings of the traditional mechanical keyboard to a certain extent and improves the safety and usab...

AI Technical Summary

Problems solved by technology

Due to the problems of high noise, easy wear, and low service life, mechanical keyboards are gradually losing market availability due to their poor water resistance, dust resistance, and oil resistance.

At present, the capacitive-sensing keyboard under the mine is better than the mechanical keyboard. Although it makes up for the shortcomings of the traditional mechanical keyboard to a certain extent and improves the safety and usability of the mine operation, it still retains the key form of the traditional mechanical keyboard. And there are too many keyboard seals, lack of explosion-proof ability for underground operations
