Measurement of Wind Speed and Direction with Ultrasonic Sensor Using FPGA

摘要：

In this paper we introduce the method of measurement of wind speed and direction based on an embedded system with multiple ultrasonic sensor.The system includes front-end circuits and back-end circuits.The Front-end circuits include the sensors low-voltage drive circuit, preamplifier circuit, filter circuit, the voltage comparator circuit and the signal isolation circuit.Back-end circuits include the signal generator circuit, the signal detection circuit, FIFO circuit, LCD driver circuit and UART protocol Circuit.Using low voltage drive drives the sensor can reduce the debugging of the system.The system can launch and receive ultrasonic signal, and get the time of flight of ultrasonic signal according to design precision after verification.All control and processing are in Field Programmable Gate Array (FPGA).FPGA is the very key factor in system design.
