Digital photography-based agglomerate fog real time early warning system and method

Abstract

The invention relates to a digital photography-based agglomerate fog real time early warning system and method. The system comprises a CCD (charge coupled device) camera, an AD (analog to digital) converter, a digital image processor, an SDRAM (synchronous dynamic random access memory), a 3G (3rd generation telecommunication) communication module, a first zigbee module, a second zigbee module, an information publishing controller, an LED (light-emitting diode) display screen and a temperature detection device, wherein the AD converter is respectively connected with the CCD camera and the digital image processor which is respectively connected with the SDRAM, the 3G communication module, the first zigbee module and the temperature detection device, the second and first zigbee modules perform data transmission by a wireless network, and the information publishing controller is respectively connected with the second zigbee module and the LED display screen. The digital photography-based agglomerate fog real time early warning system and method overcome the defects of complex structure, expensive cost, information collection difficulty, not obvious warning effect and the like of a traditional agglomerate fog early warning system, and the system has good upgradability and maintainability.

Description

technical field [0001] The invention relates to a real-time fog early warning system, in particular to a real-time fog early warning system and method based on digital photography. Background technique [0002] In recent years, with the rapid development of the economy, the mileage of expressways in our country has also been continuously extended, and the comprehensive benefits of expressways being convenient, fast, safe and smooth are constantly emerging. However, due to the expressway's fast speed, large flow rate and its own fully enclosed characteristics, once the expressway encounters special weather with low visibility, especially sudden and random fog conditions, traffic accidents are extremely prone to occur. Reduced visibility on highways caused by weather factors such as heavy fog (especially group fog), rain and snow, and sandstorms has become the main cause of traffic accidents on highways, and has caused huge losses in society, economy, people's lives and proper...

Problems solved by technology

[0008] Most of my country's meteorological monitoring equipment is imported from abroad, which is expensive and difficult to maintain. In addition, due to improper use and maintenance of equipment, many equipment have not played their due role

At present, there are also many manufacturers of visibility meters in China, mainly Tianyude’s TYD-MV visibility meters, Yingfu instruments, etc., but their systems are complicated, the sampling data is small, and the cost is high, so they are not suitable for large-scale use on expressways.

[0009] In the relevant fields at home and abroad, there are relatively few explorations and researches in this area. Up to now, there has not been a group fog early warning system with obvious warning effect, good safety performance, high degree of automation and simple operation.
