1.Product introduction ofsmall weather monitoring stations

Small weather monitoring stations, also known as small weather stations, automatic small weather stations, small weather monitoring stations are mainly used to collect parameters such as temperature, humidity, light intensity, rainfall, wind speed, wind direction, soil temperature, soil moisture, atmospheric pressure, crop seedling condition images, etc. changes and are widely used in scientific research and other fields.

Highway weather stations use comprehensive acquisition and control technology, computer software technology, communication technology and other technologies to integrate a variety of weather sensors from structure to system composition.It can continuously obtain meteorological information along the traffic line, conduct real-time monitoring of meteorological elements such as visibility, wind speed, wind direction, temperature, humidity, atmospheric pressure, rainfall, road surface conditions, etc., and complete the summary of various data through remote transmission and transmit it to the transportation department in a timely manner. It provides first-hand information for transportation-related departments to provide traffic meteorological support services along the routes. Based on this, it can provide timely meteorological information services for highway safety authorities and people's travel.

The highway weather station system consists of: weather sensors, collectors, pole brackets, power supply systems, and cloud platforms.

2. Product features

1. Visibility meter: It is composed of main components such as light transmitter, light receiver and microprocessor controller.The emitter emits infrared pulse light, and the receiver simultaneously detects the intensity of pulse light forward scattered by aerosol particles in the atmosphere. All measurement information is collected by the microprocessor controller and converted into the Meteorological Optical Range (Meteorological Optical Range) through a specialized mathematical model algorithm. MOR)

2. Six-element integrated sensor of temperature, humidity, wind speed, wind direction, atmospheric pressure and piezoelectric rainfall

3. Wind speed and direction sensor: The probe head cover is hidden to avoid interference from rain and snow accumulation and avoid obstruction by natural wind.The principle is to emit continuous variable frequency ultrasonic signals and detect wind speed and direction by measuring relative phase.

4. Piezoelectric rainfall: This piezoelectric rainfall sensor uses PVDF piezoelectric film as a rain sensing device, and uses an embedded AI neural network to distinguish raindrop signals to avoid false triggering caused by interference such as gravel, dust, vibration, etc.

5. Standard GPRS wireless transmission
