Port terminal wind speed and direction monitoring solution


Industry background
Under the influence of global climate change, coastal ports are constantly affected by gusts or typhoons, and the ports is paying more and more attention to the impact of weather on their security operations. As the port's large-scale infrastructure, the importance and security of the quay crane is beyond doubt. For ports with frequent gusts or typhoons, it is particularly important to strengthen the monitoring of wind speed and direction.
Through the wind speed and direction monitoring system to monitor the meteorological information such as wind speed and wind direction within the range of shore bridge equipment, and provide necessary safety warnings, it is conducive to the normal operation of the port business and provide guarantee for the safe production of the port.

Ultrasonic wind speed and direction instruments monitoring system
The ultrasonic wind speed and direction instruments monitoring system consists of ultrasonic wind speed and direction instruments, wireless transmission module and monitoring center PLC, which can realize real-time monitoring of wind speed and wind direction information in the entire port area, and then display it visually through the display screen. At the same time, record changes in wind speed and direction within the wharf and provide real-time warning.

Monitoring method
Two AR200 ultrasonic wind speed and direction instruments are installed at the two ends of the shore bridge,The AR200 will collect the wind speed and wind direction data on the spot, which can be displayed on a display screen in the shore bridge cabin , or remotely transmitted to the PLC of the monitoring center through the PLC configuration. After that, display and alarm functions are provided. 
When installing the ultrasonic wind speed and direction meter on the shore bridge, it is necessary to do lightning protection and grounding treatment in consideration of the high height of the shore bridge.

The corresponding products
The AR200 uses ultrasonic time difference method to measure wind speed and wind direction. The time difference method uses the difference in speed of ultrasonic waves traveling along the downwind and upwind paths to determine the wind speed and direction. It can completely eliminate the influence of installation height, temperature, humidity and pressure difference on the measurement. AR200 is resistant to pollution and corrosion by a metal casing. It has high measurement accuracy and requires no regular maintenance. It can also provide heating function according to the on-site climatic conditions to adapt to various harsh frost conditions.
