Problems solved by technology

[0002] At present, the application of touch buttons is very extensive. The traditional mechanical contact buttons have the disadvantages of being easily damaged and stuck. When there is enough capacitance, the current flowing away is enough to cause the malfunction of the capacitive screen. When the ambient temperature and humidity change, the environmental electric field changes, which will cause the capacitive screen to drift, resulting in inaccurate information on the input contacts. and other shortcomings;

Embodiment Construction

[0019] A further detailed description will be made below in conjunction with the accompanying drawings and embodiments of the present invention:

[0020] Such as figure 1 As shown, a metal panel input control system based on the piezoelectric effect includes a metal panel button 1, a piezoelectric sensor 2 is arranged under the metal panel button 1, and the piezoelectric sensor 2 is connected with a piezoelectric sensor for amplifying 2 A signal amplifier 3 for the output voltage, the signal amplifier 3 is connected with an operation judge 4 that judges the magnitude of the output voltage and the duration of the output voltage, and the operation judge 4 is connected with a controller 5 that outputs a response according to its judgment signal .

[0021] When the button is pressed, the pressing force is different, so that the deformation degree of the piezoelectric sensor 2 is different, thereby changing the real-time voltage value output by the piezoelectric sensor 2, and the ...

Abstract

The invention discloses a metal panel input control system based on the piezoelectric effect and a control method thereof, including a metal panel button, a piezoelectric sensor is arranged under the metal panel button, and the piezoelectric sensor is connected with a A signal amplifier for the output voltage of the sensor, the signal amplifier is connected with an operation judger for judging the magnitude of the output voltage and the duration of the output voltage, and the operation judger is connected with a controller for outputting a response according to its judgment signal, by touching the piezoelectric The size and duration of the sensor output voltage are used to judge whether the input key signal is valid, which greatly improves the accuracy of the input signal.

Description

[technical field] [0001] The invention relates to a piezoelectric effect-based metal panel input control system and a control method thereof. [Background technique] [0002] At present, the application of touch buttons is very extensive. The traditional mechanical contact buttons have the disadvantages of being easily damaged and stuck. When there is enough capacitance, the current flowing away is enough to cause the malfunction of the capacitive screen. When the ambient temperature and humidity change, the environmental electric field changes, which will cause the capacitive screen to drift, resulting in inaccurate information on the input contacts. and other shortcomings; [Content of the invention] [0003] The present invention overcomes the deficiencies of the above technologies, and provides a piezoelectric effect-based metal panel input control system and its control method, which can judge whether the input key signal is valid by touching the output voltage and dur...
