Description: An angle data acquisition system is designed and realized in this thesis, which based on single-chip of STC12 as the MCU. Use three axle acceleration instrument MMA7260Q to carry on the measurement of dip angle. The paper introduces the overall concept design, each module hardware composition and the software design。Introduces the hardware acceleration sensor MMA7260Q principle, the selection of micro-controller, serial communication module. The system uses the DS1302 clock chip for the angle acquisition time label, there is the keyboard, showing part of man-machine interface the system can set the alarm value perspective and the perspective of real-time, display the current data and achieve sound and light alarm. Software design introduces some of the major use of the DS1302, the perspective of data collection, storage and data communication with the host computer, and gives some important subroutine. Finally, the paper has given the actual method of angle test and result of the test.
