Research on Temperature Acquisition System of Coordinate Measuring Machine
There are problems of traditional temperature acquisition equipment,such as large volume,low measurement accuracy,wired transmission,and limited field of use,etc.To solve the above problems,the design of a coordinate measuring machine temperature acquisition system is made,which use a four wire PT100 temperature measurement circuit and ADS1220 to form a temperature acquisition module,improving the accuracy of temperature acquisition.By using CC2640 for low-power bluetooth networking design,the device power consumption is reduced,the wireless transmission is achieved,and the usage scenarios is expanded.The experimental results show that the designed temperature acquisition system has an accuracy of 0.1℃,which meets the temperature acquisition requirements of coordinate measuring machines.
