Design of the Data Acquisition System Based on STM32ABSTRACTEarly detection of failures in machinery equipments is one of the mostimportant concerns to industry 。 In order tomonitor effective of rotating machinery, we development a micro-controller uC/OS-II system of signal acquisition system based on STM32 in this paper。 we have given the whole design scheme of system and the multi—channel vibration signal in axis X ， Y and Z of the rotary shaft can be acquired rapidly and display in real—time。 Our system has the character of simple structure, low power consumption, miniaturization.Keywords：STM32； data acquisition； embedded system;uC/OS—II；1. 1。 IntroductionThe real-time acquisition of vibration in rotating machinery can effectively predict， assess and diagnose equipment operation state， the industry gets vibration data acquisition Rapidly and analysis in real-time can monitor the rotating machinery state and guarantee the safe running of the equipment。 In order to prevent failure， reduce maintenance time ， improve the economic efficiency, The purpose of fault diagnosis system can detect these devices through the vibration signal acquisition of rotating machinery ， and process the data acquisition, then it will make timely judgment of running state of equipment 。While the data acquisition module is the core part of the fault diagnosis system [1—4 ］ 。 The practical application in the industrial field， is the equipment operating parameters will be acquired to monitor equipment operating state。 In traditional data acquisition systems， the data from acquisition card are generally send into the computer， and specific software will be developed for the data acquisition. The main contribution of...
