Highway meteorological monitoring station

The highway weather station developed and produced by our company is composed of several automatic weather stations distributed along the highway network. It automatically monitors the visibility, wind direction, wind speed, temperature, humidity, rainfall, and road conditions (surface temperature, dryness, wetness, snow, ice, ice thickness, snow cover thickness) along the highway, and transmits the monitoring information to the monitoring center in a timely manner for reference by the traffic control system. In adverse or meteorological conditions, it can issue warning information in a timely manner to inform management personnel and drivers in various ways, in order to improve the safe driving level of the highway.

　　1.1 Background

With the rapid development of our country's economy, the flow of passengers and goods has greatly increased. The rapid development of highways has greatly shortened the temporal and spatial distance between provinces and important cities, accelerated the exchange of personnel, goods, technology, and information between regions, effectively reduced production and transportation costs, achieved effective resource allocation in a larger space, expanded the market, and played an important role in improving enterprise competitiveness, promoting national economic development, and social progress. The rapid development of highway construction requires the management technology of highways to keep up with the times, and road surface inspection is an important part of highway maintenance and management. Therefore, implementing automatic monitoring of highways is of great significance.

　　1.2 ImplementationAutomatic Meteorological Monitoring System for Highwaysmeaning

Severe weather conditions seriously affect the safety of highway driving and can easily lead to traffic accidents. Heavy fog and rainy weather can lead to reduced visibility, rainy and snowy weather can cause slippery roads, strong winds can affect vehicle stability, road icing and frost can significantly reduce road friction coefficient, and long-distance high-speed driving in hot weather can easily cause tire blowouts and fatigue driving. These weather phenomena can directly or indirectly pose hidden dangers to traffic safety.

If a highway meteorological monitoring station is set up along the route according to design requirements to monitor the road surface condition and meteorological information in real time, release information through a display screen, remind drivers to drive safely, ensure highway traffic safety and smoothness. With a wealth of project experience in highway meteorological monitoring and continuous accumulation, we can provide targeted and accurate solutions to customer requests for solutions.

　　1.3 Product Overview

The highway automatic weather monitoring system developed and produced by our company consists of several highway automatic weather stations distributed along the highway network. It automatically monitors the visibility, wind direction, wind speed, temperature, humidity, rainfall, road conditions (surface temperature, dryness, wetness, snow, ice, ice thickness, snow thickness) along the highway, and transmits the monitoring information to the monitoring center in a timely manner for reference by the traffic control system. In adverse or meteorological conditions, it can issue warning information in a timely manner to inform management personnel and drivers in various ways, in order to improve the safe driving level of the highway.

The system consists of a highway automatic weather station, data transmission, data processing application center, and road monitoring. The meteorological elements that can be observed by the automatic weather station on highways include conventional meteorological elements (wind, temperature, humidity, rain, pressure), visibility, and road conditions (road temperature, dryness and wetness, snow, icing, etc.).

　　2、 Technical characteristics of automatic meteorological monitoring system for highways

1. Road snow measurement technology

Using laser measurement technology, high-precision measurement of ice and snow can be achieved, with a thickness of over 1 meter (similar products can only reach 1 centimeter) It can accurately measure the snow thickness on the road surface )

1.1 Laser detection principle, detecting the thickness of road surface water accumulation, road surface icing, road surface snow and ice layer separately; At the same time, it can measure factors such as visibility, air temperature and humidity, road surface temperature, wind speed, wind direction, air pressure, rainfall, etc.

1.2 Remote sensing can detect road conditions from a distance, even in congested traffic conditions.

1.3 Easy installation and maintenance, low maintenance cost, salt spray resistance, and can be used in coastal areas.

1.4 Non embedded installation is fast and easy.

2. The system has a standard communication interface RS232 that can be connected to a microcomputer for data download, allowing for real-time monitoring of data and independent operation to display and store meteorological element values.

3. It has wireless network communication function, and with a wireless communicator, it can achieve long-distance network monitoring or remote telemetry data through GSM/GPRS network. Unrestricted by distance, each meteorological monitoring network is equipped with a wireless communication port, and the main control microcomputer of the meteorological center monitoring station uniformly monitors the data of all meteorological stations in the network to achieve the integration and statistics of meteorological data throughout the network. Mobile storage technology can also be used to transfer data.

4. The automatic weather station management software can run in environments above WINDOWS98, displaying real-time data from various sources, updating every 10 seconds, and automatically storing hourly and hourly data (storage time can be set). It can be connected to a printer to automatically print and store data, with a storage capacity of more than one year. The data storage format is EXCEL standard format, which can be called by other software.

5. The automatic weather station data collector adopts a high-performance microprocessor as the main control CPU, a large capacity data storage, and can continuously store hourly data for more than three months. It is designed according to industrial control standards, has a portable shockproof structure, a large screen Chinese character graphic LCD display, and a touch sensitive film button. Suitable for use in harsh industrial environments. Equipped with power outage protection function, when the AC power is cut off, it is powered by rechargeable batteries and can be maintained for more than 72 hours.

6. The system has multiple power supply methods, including a dual-purpose AC/DC power supply system and optional solar cell power supply

7. Multiple indoor and outdoor display screens can be selected for matching.
