Data acquisition and conversion module for robot polishing workstation

Abstract

The invention provides a data acquisition and conversion module for a robot polishing workstation. Thedata acquisition and conversion module comprises a control unit, the control unit is respectively connected with a temperature measurement unit, a 4-20mA sensor signal acquisition unit, a bus communication interface unit and a temperature measurement circuit calibration unit, and a power supply unit provides power to the control unit, the temperature measurement unit, the 4-20mA sensor signal acquisition unit, the bus communication interface unit and the temperature measurement circuit calibration unit; the temperature measurement unit is used for converting a thermistor signal into a voltage signal, the bus communication unit is used for sending a converted digital signal to an upper computer through an RS485 or CAN bus, and the temperature measurement circuit calibration unit is used for automatically calibrating a bridge resistance value of the thermistor temperature measurement unit. The data acquisition and conversion module can be used for acquiring temperature, humidity, force sensing and vibration signals, converting the analog quantity into digital signals, and outputting the digital signals through the RS485 or CAN bus. The module has the advantages of being high in precision, low in cost and capable of being widely compatible and applied.

Description

technical field [0001] The invention relates to the field of robot polishing workstations, in particular to a data acquisition and conversion module for robot polishing workstations. Background technique [0002] In recent years, with the continuous advancement of robot and machine vision technology and the continuous increase of labor costs, the industry has increasingly strong demand for the use of high-precision industrial robots for workpiece grinding operations. In order to ensure the normal operation of the robot grinding workstation, it is necessary to install a higher Multiple temperature, humidity, force and vibration sensors monitor the working status of the robot. Most of these sensors do not have RS485 or CAN bus communication capabilities, and a few sensors with bus communication capabilities are often expensive, and have different functions and different types produced by different manufacturers. The sensor has the problem of data frame protocol confusion, whic...
