In angle measurement, the rotation of measured vector may cause cable winding. To solve the problem, a wireless angle measurement system is put forward based on CC1101 Radio Frequency(RF) chip. The tilt sensor is used to collect the angle data in real time, and data transmission is realized by wireless module. Finally, analysis and processing are made to the data received, and the real-time moving state of turntable or platform is obtained. The composition and working principle of the system are presented, a wireless inclination measurement prototype is established based on CC1101 RF chip. The wireless communication module drive program and measurement system application program are given, and angle measurement test is made. Experimental results verify the feasibility of the measurement system.
