Impulse-based information input device

Abstract

The invention discloses an impulse-based information input device. The impulse-based information input device comprises an impulse detection sensor, a data acquisition unit and a microprocessor, wherein an impulse signal setting module and an impulse signal identification module are arranged in the microprocessor; the impulse detection sensor is used for detecting impulse signals and providing the detected signals for the data acquisition unit; the data acquisition unit consists of a digital-to-analog converter, converts analog signals output by the impulse detection sensor into digital signals and sends the digital signals to the microprocessor; the impulse signal setting module is used for setting a condition for starting a corresponding function execution module; and the impulse signalidentification module is used for identifying the acquired impulse signals, extracting characteristic signals from the impulse signals, and sending an execution signal to the function execution module when the characteristic signals and the impulse signal setting module have same setting conditions, and the function execution module executes a given function. The impulse-based information input device has the characteristics of simplicity, concealment and low cost.

Description

technical field [0001] The invention belongs to an electronic equipment information input device, in particular to an impact-based information input device. The present invention can be used as an input method or device for various electronic devices, and is especially suitable for but not limited to the triggering of emergency or common mobile phone functions, such as alarm or dialing of common numbers, opening of door locks, etc. Background technique [0002] At present, the input operation of electronic equipment mainly adopts buttons or touch. Generally, it is necessary to look at the buttons and the screen to complete the input. However, in an emergency such as being hijacked, when the mobile phone is placed in a pocket or bag and the display screen cannot be seen Difficult to complete information entry. Contents of the invention [0003] In view of this, the present invention provides a shock-based information input device, without looking at the keyboard and displa...
