In this paper, an indoor two-dimensional positioning system was designed and implemented based on radio frequency and ultrasonic technology by comparing several common indoor positioning methods. The system adopts C51 series single chip microcomputer as main control chip, nRF24L01 as radio frequency(rf) communication chip, chip combining ultrasonic launching and receiving circuit, the fusion of radio frequency and ultrasonic techniques for two-dimensional plane on a bit of location information to obtain, and the measurement results with the LCD12864 display. The article detailed analysis of the system working principle and the design of the measurement circuit, by the actual measurement data with the results of error analysis, the measurement data error within 2%, the error can be thought of.
