[0036] First, the application scenario of this disclosure is explained. In traditional wind speed measurement, mechanical anemometers transmit voltage signals, which are low-cost but have limited accuracy. Ultrasonic anemometers, as a product of modern technology, utilize the ultrasonic time-of-flight method to achieve high-precision wind speed and direction measurement, and are integrated with control systems such as PLCs through communication methods, significantly improving automation levels. However, troubleshooting existing ultrasonic anemometers is complex when they malfunction. Due to the use of special communication protocols, traditional electrical detection methods such as voltage and resistance methods are difficult to apply directly to fault diagnosis, forcing maintenance personnel to rely on replacement methods. This not only increases spare parts procurement costs but also, because the contact points are prone to slight displacement during replacement, can directly render the anemometer unusable, further exacerbating the cost burden. Furthermore, the replacement method involves a long fault handling time, averaging 5 hours, severely impacting system maintenance efficiency and operational reliability. Therefore, this disclosure provides an anemometer detection and diagnostic device and system, aiming to simplify the fault handling process, reduce spare parts procurement costs, shorten fault handling time, and improve maintenance efficiency and overall system reliability to overcome the shortcomings of existing technologies. The following describes this disclosure with specific embodiments.
