The contact surface of the pressure sensor is perpendicular to the extending direction of the ship body, so that the pressure sensor is used for receiving front and back acting forces in the horizontal longitudinal extending direction of the ship body, particularly the acting force of a sportsman to the front of the ship body when stepping on the ship body and the acting force of the sportsman to the back of the seat. It should be noted that, because the touch surface of the pressure sensor is perpendicular to the extending direction of the ship body, the pressure sensor receives the pressure component directly acting on the horizontal and longitudinal extending direction of the ship body, so that for the pressure of the athlete on the ship body in other directions, the invention can actively eliminate the impurity pressure component in other directions, that is, the monitored pressure data is effective data, thereby improving the overall monitoring effect.
The data analysis module acquires acceleration information of multiple directions on the acceleration sensor and analyzes the acceleration information of the multiple directions, specifically: acquiring the acceleration information of the first direction, the acceleration information of the second direction and the acceleration information of the third direction, wherein the first direction is the horizontal longitudinal extending direction of the ship body, the second direction is the transverse direction of the ship body, the third direction is the direction vertical to the upper surface of the ship body, the obtained acceleration information comprises the acceleration magnitude and the acceleration period of the horizontal longitudinal extending direction of the ship body, wherein the acceleration sensor collects the acceleration information of the ship body, so the acceleration can be dynamically changed along with the motion state of the athlete, when the athlete applies force to the paddle, the acceleration sensor acquires acceleration in a first direction, a second direction and a third direction, and uploading the acceleration information in the first direction, the second direction and the third direction to the data analysis module through the LORA wireless communication module, and processing the acceleration information.
