1. Background introduction
The road traffic system is an important link in the transportation and circulation of personnel and materials, and the toll station of the expressway is the top priority of road traffic. As the toll management of expressways mainly relies on toll stations scattered all over the place, and these toll stations are located in uncertain locations and far apart, there is an urgent need for a long-distance control, fast, and simple operation monitoring system to complete the control. The toll station conducts long-distance gathering monitoring and management. The toll station's vehicle congestion, intelligent analysis and data aggregation have become an urgent problem to be solved by the toll station's intelligent security system.
Second, demand pain points
① Monitoring equipment is difficult to manage due to different road conditions and scenes, different types of equipment, and scattered distribution;
② Traditional security monitoring does not have the intelligent analysis capability of video monitoring, and data collection is not timely;
③ It does not have the computing power of big data , Unable to judge or predict vehicle behavior;
④ unable to provide intelligent warning information, staff can not detect and predict vehicle traffic in time, thus bringing lower work efficiency to staff.
The main purpose of establishing an intelligent analysis security monitoring system for expressway toll stations is:
- Strengthen the safety monitoring of high-speed toll stations;
- Analyze and warn vehicles of malicious jamming, provocation and other incidents in time;
- Improve the efficiency of vehicle traffic at toll stations;
- Big data analysis to calculate the number of vehicles, types of vehicles and the probability of passage, and predict whether to open more channels in advance;
- Provide management efficiency and work of managers.
Three, the solution:
At present, the EasyCVR integrated management system, an intelligent video analysis platform developed by TSINGSEE Qingxi Video, has brought good news to toll stations. Various toll stations can install monitoring equipment in important locations and areas, such as lanes and toll stations. The video stream of the surveillance equipment is transmitted to the intelligent video analysis platform, which can perform functions such as artificial intelligence analysis, data aggregation, alarm information sending and picture capture, and the platform provided by Qingxi Video can provide API interfaces to facilitate secondary development and platform expand.
Location map of equipment layout:
1) The monitoring equipment is deployed at the curve of the toll station to detect the number of vehicles entering the curve in advance, summarize and perform intelligent analysis, and send warning information to the management personnel to facilitate the management of the import and export conditions of the import and export channels;
2) At the toll station A monitoring device is installed on the top of the entrance and exit passages, so that it is convenient to count the number of vehicles in each passage, and more accurate data statistics and summary;
3) Monitoring equipment is also installed in the toll room, which can detect vehicle conditions at close range. Ensure driving safety and staff safety.
Fourth, the program advantages
This solution can not only be connected to EasyCVR through GB28181, Ehome protocol, but also can install EasyNTS equipment in the intranet to establish a transmission channel with the public network, so that it can be connected to the video intelligent analysis platform through Haikang SDK, Onvif/RTSP; At the same time, it has local storage capabilities, supports H265 video stream encoding and decoding, and supports functions such as TV walls. The most important thing is the ability to provide intelligent video analysis, data aggregation, unified management of equipment, and sending of alarm information.
Its main realization capabilities include:
- Through the system, the live images in the monitoring area are transmitted back to the command center, so that managers can directly grasp the traffic conditions such as vehicle queues, jams, and signal lights, and adjust signal timing in time or use other means to divert traffic and change the distribution of traffic flow. To achieve the purpose of alleviating traffic jams.
- The management personnel keep track of the traffic guard videos and the traffic conditions of large-scale gatherings at any time, and mobilize the police force in time to ensure the smooth flow of traffic guard videos.
- Through the video recording of emergencies, the ability to deal with emergencies is improved.
- Through video recording of violations, the monitoring system can play a positive role in economic and social benefits.
- Through the combination of the horizontal pseudo-matrix monitoring system and the digital network, it can easily manage the entire network.
