A non-destructive testing device and method for fruit turgor pressure

Abstract

The application provides a fruit turgor pressure nondestructive detection device and method, which comprises a support, a plurality of force arm rods hinged to the support, and the plurality of force arm rods are arranged in a ring shape; a pressure sensor is arranged at the end of each force arm rod away from the support; a displacement sensor is further arranged on the support and used for measuring the rotation amount of each force arm rod; a plurality of elastic members are further arranged, the plurality of elastic members correspond to the plurality of force arm rods one by one, each elastic member is used for pulling the corresponding force arm rod to press on the fruit to be detected, and a data processing module calculates the turgor pressure according to the data detected by the above sensor. In the above technical scheme, the pressure sensor is used to collect the signal of the force arm rod pressing on the fruit to be detected, the displacement sensor is used to detect the displacement amount when each force arm rod rotates, and the pressure value applied to the fruit to be detected by the force arm rod is matched, so that the turgor pressure of the fruit to be detected can be calculated. When the above device is used for detection, the fruit does not need to be damaged, and the detection effect is improved.
