Abstract

The invention provides a pressure sensor calibration device and a calibration method, belonging to the technical field of sensor calibration, including a fixed bracket, a pressure sensor to be calibrated, a lifting assembly, a pulley assembly, a force contact and a calibration processor; a pressure sensor to be calibrated Installed on the fixed bracket; the lifting component is slidably connected with the fixed bracket; the pulley component includes a fixed pulley block and a pulley rope, and the lifting component and the weight seat are connected at both ends of the pulley rope; Move upward to contact with the upper pressure sensor; the calibration processor collects the output signal of the pressure sensor to calibrate the pressure sensor. The pressure sensor calibration device provided by the present invention can calibrate the pressure sensor without using additional sensors, which saves the production cost and reduces the difficulty of use; the lifting component is automatically raised by using the pulley component, which reduces the error caused by human intervention , which improves the accuracy of the calibration results.

Description

technical field [0001] The invention belongs to the technical field of pressure sensor calibration, and more specifically relates to a pressure sensor calibration device and a calibration method based on the calibration device. Background technique [0002] As the terminal perception and grasping tool of intelligent robots, the dexterous hand has high dexterity, versatility and adaptability, and can complete various grasping and manipulation tasks. It is widely used in dangerous environment detection, outer space exploration, Logistics handling, industrial assembly, rehabilitation medicine, intelligent manufacturing and agricultural picking and other fields. [0003] In the grasping operation of the dexterous hand, it is necessary not only to avoid the object being grasped from slipping due to too small grasping force, but also to prevent damage to the grasped object due to excessive grasping force. Steady grasping of objects. To be able to achieve minimum force grasping, ...
