A safety joint control system and method for highway construction area

Abstract

The invention relates to a road construction area safety joint control system and method. The method comprises a safety joint control system is set in advance; a vehicle is continuously monitored by aradar preset in a vehicle monitoring and early warning module, vehicle movement parameters and position parameters are obtained, and prompt information is sent to the vehicle monitoring and early warning module in the safety joint control system, a construction area information prompt module and a vehicle driving state prompt module; the vehicle monitoring and early warning module is used for evaluating a vehicle intrusion risk according to a risk assessment model of a vehicle intrusion construction area, carrying out grading early warning and sending a risk grade wireless signal to an intrusion detection alarm and signal relay unit, a main controller and a remote monitoring unit in the safety joint control system; when the risk is evaluated to be risky, two layers of intrusion detectionequipment including the radar and an intelligent detection track spike are started, and the next step is started; three layers of intrusion detection equipment are started according to the risk gradewireless signal.

Description

technical field [0001] The invention relates to the technical field of road safety production, in particular to a safety joint control system and method for road construction areas. Background technique [0002] With the rapid development of our country's economy, the maintenance, reconstruction and expansion projects of expressways are gradually increasing, and the construction areas of expressways are also increasing. In the process of expressway maintenance, the method of maintenance while opening to traffic is often adopted, and relevant safety facilities are arranged within the construction area of ​​the maintenance project and its upstream and downstream to ensure the safety of maintenance workers and remind passing vehicles to slow down and avoid; In highway reconstruction and expansion projects, the existing lanes are often closed to a large extent, and facilities such as isolation water barriers and anti-collision isolation piers are used to ensure the safety of the...

AI Technical Summary

Problems solved by technology

It has the following defects: 1. The detection ability of the infrared detection unit of the front-end detection of the system is limited by the principle of infrared diffuse reflection, and the detection distance is relatively short, so there may be a risk of missed detection; the principle of infrared diffuse reflection is also easily affected by the environment. generate false positives

2. The system only provides a detection and alarm function for vehicle intrusion, but cannot remind the driver of the driving situation of the vehicle, and has no early warning ability for the driver

3. The detection of the system is carried out near the construction area. At this time, the vehicle intrusion is detected immediately, and the time left for the workers in the construction area to escape is relatively small, which restricts the use effect of the system.

4. The detection system is powered by batteries, and the use time is limited, so it cannot adapt to the scene of long-term construction

5. The system does not have the data collection and remote alarm capabilities at the time of the intrusion accident, and cannot provide accident information and image and video materials for the management center

It has the following defects: 1. The system plays the role of prompting the driver of the traffic flow information in the construction area ahead, but it cannot avoid the risk that the construction personnel cannot be effectively reminded in advance after the vehicle breaks into the construction area due to various reasons

2. The detection unit smart bucket is a non-standard item, and the installation of the construction area is an additional facility, which is likely to overlap with the existing safety cones, causing confusion. There will also be some safety risks when non-standard products are directly installed on the road.

3. Detecting traffic flow through smart barrels will cause large errors due to overlapping vehicles, which will inevitably interfere with the accuracy of the final intelligence and affect the effect of early warning

4. The smart barrel is powered by batteries. Traffic detection and wireless transmission are functions with high power consumption. Therefore, the use time of the system will inevitably be restricted, and it cannot adapt to long-term construction scenarios.

5. Similarly, the system does not have the data collection and remote alarm capabilities at the time of the intrusion accident, and cannot provide accident information and image and video data for the management center, which is not conducive to the construction management center's remote monitoring of construction, immediate disposal, and after-the-fact evidence collection
