Highway operation safety-based mobile monitoring and early warning system and method

Abstract

The invention discloses a highway operation safety-based mobile monitoring and early warning system and method. The system comprises a data acquisition unit, a data storage unit, a data processing unit, an electronic display screen and a wireless communication module, wherein the data acquisition unit, the data storage unit, the electronic display screen and the wireless communication module are all connected with the data processing unit; the system is arranged on a vehicle; and an accumulator is adopted to provide power. The method specifically comprises the following steps of: constructing a basic database; acquiring dynamic data by the data acquisition unit in real time; comparing real-time road condition parameters with safe road condition parameters by the data processing unit to generate early warning information; and transmitting the real-time road condition parameters and the early warning information to a monitoring center by the wireless communication module. According to the system and the method, the defects of the conventional fixed monitoring system and patrol vehicle can be made up, real-time detection and analysis of the highway road condition parameters are effectively improved, and the highway operation safety level and the emergency management capacity are improved.

Description

technical field [0001] The invention relates to a mobile monitoring and early warning system and method based on highway operation safety. Background technique [0002] In the actual operation of expressways, changes in the natural and human environment have a certain impact on traffic safety. Some domestic studies call this kind of change disturbance a catastrophic event. There are many catastrophic events on expressways, mainly including traffic congestion, traffic accidents, traffic conflicts, severe weather, geological disasters, road maintenance operations, etc. Domestic research divides expressway catastrophic events into emergency events, disaster events, planned events, traffic accidents, etc. There are five types of accidents and conflict risk events. The normal operation of expressways is usually disturbed by various catastrophic events, which are mainly manifested in two levels: one is that catastrophic events cause damage to expressway infrastructure or lack of ...

AI Technical Summary

Problems solved by technology

[0006] (1) The monitoring range of the equipment is limited. Under the constraints of economic conditions, the density of equipment installation is difficult to achieve full-range monitoring of the expressway without monitoring blind spots (the so-called full-range monitoring refers to including every section of the expressway into the monitoring range), For example, video surveillance equipment can only monitor traffic information of a small section of road, road weather stations can only monitor single-point weather information and road surface information, and induction coils can only detect cross-section traffic information;

[0007] (2) Due to the existence of monitoring blind spots, these devices are powerless to monitor sudden catastrophic events with small impact areas, such as cloud fog, road icing, and traffic accidents that are common on expressways. Only these catastrophic events happen to happen within the monitoring range , can be detected in time and accurately;

[0008] (3) The maintenance and repair of equipment is difficult, which will inevitably affect the normal traffic. When the equipment needs to be maintained, overhauled or replaced, it will affect the normal traffic operation of the expressway, and even affect the driving safety on the expressway

[0009] In addition, although mobile monitoring equipment such as patrol cars have been used on highways, the detection of catastrophic events is still manual visual inspection. Although it can detect the occurrence of catastrophic events, it cannot accurately detect the situation of catastrophic events. For example, a patrol car finds a cloud of fog on a certain road section, but it cannot know the specific visibility of the fog, that is, it cannot obtain the specific road condition parameters on the expressway in time, cannot provide early warning information for the safety of the expressway operation, and cannot effectively reduce the danger on the expressway. risk of accident
