The invention discloses an intelligent touch height measuring instrument based on a flexible array pressure sensor. The intelligent touch height measuring instrument based on the flexible array pressure sensor comprises a sensing element, a central processing module, a digital display panel, LED (light-emitting diode) lamp strips, a loudspeaker and an instrument body, wherein the sensing element is the flexible array pressure sensor; the sensing element generates a sensing signal and transmits the sensing signal to the central processing module; the central processing module comprises a transmission module, a microcontroller, a display module, a voice module and a storage module; the microcontroller receives the sensing signal of the sensing element through the transmission module, converts the sensing signal into a digital signal, and then transmits the digital signal to the display module, the voice module and the storage module; the display module drives the digital display panel to display a touch height value; the voice module drives the loudspeaker to announce the touch height value; the storage module stores touch height data. According to the intelligent touch height measuring instrument based on the flexible array pressure sensor, the flexible array pressure sensor is adopted as the sensing element, the detection precision, the reliability and the stability are higher, and the intelligent touch height measuring instrument based on the flexible array pressure sensor has a detection mode and a training mode, and supports digital display, voice announcement and the wireless transmission and downloading of the data.
