Security Monitoring in Transportation Industry

According to the Ministry of Communications, “The Economic Operation of Highway Water Transportation in the First Half of 2009”, in 2009, 111 highway construction projects were newly started in the country, with a total mileage of 12,000 km. The total planned investment is about 700 billion yuan. According to the current plans under construction and investment plans, the annual increase in freeways mileage of expressways in the next three years is expected to remain at a level of 6,000 kilometers. Under this kind of construction boom, the investment in the electromechanical system, which is an important part of the highway infrastructure, will also be significant, bringing abundant business opportunities to the security industry. The next round of market scale of the highway monitoring system will reach Ten billion or so.

The highway monitoring market ushered in the well blowout market. In addition to the “emphasis” on numerous new construction projects, the highway electromechanical system also ushered in the peak period of transformation. The period of electromechanical equipment for expressways is approximately seven or eight years. The electromechanical system of the expressway will undergo equipment modification and replacement every eight years. The electromechanical system of the projects in the early construction highway “upsurge” is facing transformation, which will also bring new opportunities for integrators and suppliers. In addition to normal maintenance and maintenance, the peak period of transformation mainly includes expansion and reconstruction projects that are faced with the needs of highway operations. The early construction was mainly for the provincial trunk roads, such as the Shanghai-Hangzhou, Beijing-Zhuhai and Beijing-Shanghai sections. Take the Beijing-Zhuhai expressway as an example. With the rapid increase in traffic volume year after year, the overall road service level has been significantly reduced. At present, some road sections are being reconstructed and the original 4 lanes will be expanded to 8 lanes. The demand for expansion will inevitably bring application to the monitoring system. More business opportunities.

In recent years, more and more high-speed monitoring systems have put forward newer and higher demands. The products of the expressway monitoring system are constantly being updated, such as the 480 lines from the previous years to the present 600 lines, and the evolution from the traditional analog cameras to the current digital high-definition megapixel cameras. The control system has also evolved from a single management model. To the current video networking unified management model.

Analysis of Highway Digital Video Surveillance System The development of expressways in China is very rapid. The replacement of surveillance products is also relatively rapid. The simulation system and digital system of the existing expressway monitoring system coexist, and at the same time the technical level of the expressway monitoring system is improved, it is also required. Take full account of the existence of existing analog monitoring systems. In the process of upgrading and renovating some highways using analog surveillance systems, it is not possible to have all the systems in the clinics - and this will result in a huge waste of investment. How to integrate the diagnostic-system usefulness into the system and take into account the emerging application of technological functions will be a test of the excellence of a surveillance system.

At this stage of the network digital video surveillance technology, the status quo of the development of expressways should be fully taken into account, and a set of digital video surveillance systems tailored for the expressway monitoring industry. Such a system not only has many excellent monitoring technologies of today, but also can be perfectly compatible with the analog matrix monitoring system.

The video surveillance system of highway network video surveillance system is considered as an integral part of the electromechanical system engineering of highways and plays an irreplaceable role in highway management. The deployment of surveillance systems on highways with large traffic flows and fast speeds has become a high speed. An important means of modern highway management. During the “Eleventh Five-Year Plan” period, the state issued the “National Strategy for Informatization Development from 2006 to 2020”. The Ministry of Communications has determined the development direction of traffic informatization according to the development strategy, and put forward higher requirements for information system construction of monitoring systems. - On the basis of highway video surveillance, digital and networked video transmission equipment is used to achieve high-quality signal transmission. And set up a provincial network monitoring center to conduct unified monitoring, management, and dispatch of all expressways in the province, and integrate with office automation systems, geographic information systems, comprehensive emergency command and dispatch platforms, call centers, and other data systems. Abnormal conditions can be linked with other information systems, quickly and effectively adopt emergency rescue plans, and improve the overall level of operations management.

A brief discussion on the interval speed measurement system of the inter-vehicular speed-measuring system is based on advanced vehicle capture technology, vehicle license plate recognition technology, and network communication technology to realize a new type of speeding illegal evidence collection system. The system determines whether speeding is over by calculating the average speed of the vehicle passing through the road, effectively solving the easy evasion of single-point speed measurement, and more effectively controlling the occurrence of illegal activities such as speeding and reducing speeding.

Through the automatic capture system of vehicles installed on the expressway, it continuously captures vehicle pictures, identifies and records vehicle information that passes on multiple sections in real time, including vehicle number plates, passing time, panoramic vehicle pictures, and speed of each section point, etc. This information is uploaded to the central processing platform through the network (wired or wireless), comparing the travel time of the same vehicle in two sections in the same direction, and then calculating the average speed of the vehicle through this section based on the distance between the two sections. According to the average speed to determine whether speeding. If there is overspeed behavior, the illegal vehicle data and pictures will be automatically audibly and visually alarmed through the background management platform, and can be sent to the nearby and on-site duty traffic police as required by SMS or posted on the expressway display. On the screen, promptly inform and warn more vehicles against illegal vehicles. All illegal vehicles and related pictures obtained by the system will be provided as illegal sources to the offending system for further processing.

The application of expressway monitoring system in expressway projects is to collect, inform, and forecast all kinds of information in front of the road, such as traffic volume, accidents, road conditions, etc. in a timely, accurate, and complete manner through field facilities along the line (various types of devices for detection, display, etc.). The executive center intuitively understands the traffic conditions through the monitoring center's monitoring (display) equipment. In the event of a traffic anomaly, it is possible to identify accidents or hand-cranked areas and issue corresponding guidance and rescue information in real time.

Highway monitoring system is mainly composed of three parts: information collection subsystem, video surveillance system and information providing subsystem. The information collection subsystem includes vehicle detectors, meteorological detectors, emergency telephones, and patrol cars. The video surveillance center is the top layer of the highway full-line monitoring system, namely the control center, and is mainly responsible for the monitoring and control of traffic conditions within the entire line. The information provision subsystem includes traffic signs, markings and signals, etc. It is the main form of traffic surveillance management for automotive users.

Video surveillance system as a highway monitoring system is essential, the entire monitoring system includes the front-end part, control and transmission part and the back-end display part. At present, video surveillance of highways is mainly distributed in toll stations, roads and service areas.
