Title: SPEED MONITORING SYSTEM WITH PHOTOELECTRIC COUNTING FOR WIND POWER GENERATOR
Abstract:
A speed monitoring system with photoelectric counting for a wind power generator, comprising a shaft (2) and a number of blades (2), the shaft (3) is arranged at one side of a body (5), and the blades (2) are evenly distributed at the outer periphery of the shaft (3) in an axis direction, two sides of the blades (2) are provided with a speed monitoring device, which comprises a transmitting mechanism (1) and a receiving mechanism (4), the transmitting mechanism (1) and the receiving mechanism (4) are positioned at two sides of the blades (2), the speed monitoring system with photoelectric counting used for the wind power generator changes, through the rotation of the blades (2), the time when the receiving mechanism (4) receives the infrared ray so that the rotational speed is monitored in real time, meanwhile, a wireless communication module is used for wireless transmission of data, thereby ensuring that the staff can perform a remote real-time monitoring on the speed of the wind power generator and make the system more intelligent; furthermore, the use of conventional components in the photoelectric detection circuit of the speed monitoring device not only ensures the reliability of monitoring, but also reduces production costs and improves the practical value of the monitoring system.
