Expressway weather monitoring system

Abstract

The invention discloses an expressway weather monitoring system, relating to the technical field of traffic safety facilities. The expressway weather monitoring system comprises weather monitoring point devices arranged at each road section and district of the expressway, and control terminals arranged at the entrances of the expressway, wherein the weather monitoring point device comprises a main microprocessor, an environment temperature measurement module, a wind direction transducer module, an ice transducer module, a visibility measurement module, a CAN (Controller Area Network) bus transmission and receiving driver, an earth surface temperature measurement module, a clock chip, a GSM (Global System for Mobile Communications) / GPRS (General Packet Radio Service) remote communication module, a wind speed transducer module, an RS 232 communication interface circuit and a CAN bus; and the control terminal comprises a GSM / GPRS remote communication module, a monitoring display module and a PC work station. The invention has the advantages of reliable work, high cost performance and long service life, and is suitable for the application occasion of expressway with complicated environmental conditions.

Description

technical field [0001] The invention relates to the technical field of traffic safety facilities, in particular to a highway meteorological monitoring system. Background technique [0002] With the rapid development of expressways and the sharp increase in the number of automobiles, traffic accidents on expressways have become more frequent, especially rear-end collisions and serial rear-end collisions caused by frost, fog, rain and snow. To this end, a meteorological monitoring device is set up on the expressway, and the meteorological information of the monitored road section is released in real time, as well as the driving safety parameters of the monitored road section comprehensively generated by the meteorological information, including information on roads, safe vehicle distances and vehicle speed thresholds. Security matters. [0003] The invention patent application with application number 200910060562.4 and date of application is 2009-01-16 discloses "Highway Anti...

Problems solved by technology

[0005]2. On the technical level, there is no ice and snow sensor that can be used on highways, and the monitoring of ice and snow is still based on manual observation

The disadvantage of the ultrasonic anemometer is not only limited by the ambient temperature and price, but also affected by rain, snow or dust, just like the heat book temperature difference anemometer.
