Abstract

The invention provides a pressure sensor calibration device and calibration method, and belongs to the technical field of sensor calibration, and the device comprises a fixed support, a to-be-calibrated pressure sensor, a lifting assembly, a pulley assembly, a force application contact, and a calibration processor. A to-be-calibrated pressure sensor is installed on the fixing support. The liftingassembly is slidably connected with the fixing support. The pulley assembly comprises a fixed pulley block and a pulley rope; the lifting assembly and the weight seat are connected to two ends of thepulley rope; the force application contact is installed on the lifting assembly, moves upwards along with the lifting assembly and makes contact with the pressure sensor above the force application contact. The calibration processor collects output signals of the pressure sensor and calibrates the pressure sensor. According to the pressure sensor calibration device provided by the invention, the pressure sensor can be calibrated without using an additional sensor, so that the manufacturing cost is saved, and the use difficulty is reduced; the pulley assembly is used for enabling the lifting assembly to automatically ascend, errors caused by human intervention are reduced, and the accuracy of the calibration result is improved.

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, ...
