[0032] An integrated module 4 consisting of a measurement module, a Bluetooth module, and a data processing module is connected to the side of the upper green skin 102 close to the lower green skin 101;

[0033] The main function of the signal acquisition module is to collect the motion data of the intelligent electronic fruit. It should be composed of a six-axis or nine-axis electronic sensor with an integrated accelerometer and gyroscope.

[0049] Working principle: When in use, the invention fixes and hangs the branches 8 on each intelligent electronic fruit 1 in the experimental site, and then controls the host computer through the main control board to send a signal to cut off the power to the electromagnet 6 and disconnect it from the iron sheet 7, thereby causing the intelligent electronic fruit 1 to fall. When the intelligent electronic fruit 1 begins to vibrate under forced vibration, the signal acquisition module in the integrated module 4 begins to collect vibration data and transmits the data to the data processing module through the serial port. The data processing module performs preliminary processing on the data, calculates the module of the acceleration received by the fruit, and uploads the data to the main control board through the Bluetooth communication module. If the module of the acceleration reaches the threshold at this time, after the vibration data of each fruit is uploaded to the main control board, the main control board integrates the data, ensures the synchronization of the data collected by each fruit through the RTC clock, and then prints the data through the serial port monitor of the host computer. The host computer saves the data to a document and then post-processes the data as needed.
