What is a high-speed weather detector?

As road transport plays an increasingly important role in the country's economy, it takes on more and more transport tasks. However, the uncertainty of weather, especially under severe weather conditions, poses a major threat to highway traffic safety. This not only interferes with the normal operation of transport, but more critically, it poses a serious risk to the safety of people's lives and property. Therefore, enhancing the transport capacity of highways, improving their adaptability and resilience to unfavourable traffic environments, and ensuring the safety, efficiency and smoothness of highway operations have become the focus of great attention from all walks of life.

This system integrates several key components to ensure efficient and safe operation of road traffic. The core of the system consists of advanced traffic weather observation devices such as visibility meters, road condition sensors, wind speed and direction sensors, and temperature and humidity sensors, which form the infrastructure for information collection. The information dissemination unit is responsible for translating surveillance strategies into warning and control instructions, which are communicated to drivers through field devices such as variable message boards (VMBs). The system is also equipped with a computer server and monitoring platform software to realise the monitoring networking function. In addition, channels for road safety services are provided to the public through Internet information push and mobile phone APP. The whole system is supported by a system support framework consisting of a control unit, a transmission unit, a power supply and distribution unit, and an information processing unit to ensure its stable operation.

The high-speed weather detector has the ability to monitor a range of key meteorological parameters, accurately detecting visibility and a variety of weather conditions, including rain, sleet, snow, hail, sleet, fog and haze. The system is also capable of measuring environmental factors such as atmospheric temperature, humidity, wind direction and speed, and using remote sensing technology to assess the actual condition of the road surface, such as dry, wet, icy, snowy or mixed ice and water. By analysing changes in these meteorological elements, the system is able to predict and warn of current weather conditions and their evolution, providing important decision support for road traffic safety.
