The invention provides an intelligent balance beam based on a flexible pressure sensor. The intelligent balance beam comprises a balance beam wooden board, wherein the flexible pressure sensor is arranged on the upper surface of the balance beam wooden board; the pressure sensor is connected to a data acquisition module; the data acquisition module is sequentially connected to a data transmission module, peripheral processing equipment and audio/video output equipment; the data acquisition module acquires analog signals of plantar pressure distribution and pressure footprint information acquired by the flexible pressure sensor, the analog signals are converted into digital signals by virtue of an A/D converter and then the digital signals are transmitted to the data transmission module; the digital signals are also transmitted to the peripheral processing equipment by virtue of the data transmission module, and the peripheral processing equipment is in charge of receiving the digital signals and controlling the audio/video output equipment to execute corresponding operations. The intelligent balance beam based on the flexible pressure sensor provided by the invention is stable and reliable, and a trainee can be prompted and guided in real time in the forms of voice and pictures, so that the training efficiency of the trainee is guaranteed.
