Expressway is the symbol of national modernization. The rapid development of expressway transportation network has effectively improved the structure and transportation efficiency of highway transportation in China, and played an extremely important role in promoting China's economic development. With the continuous improvement of people's living standards, the number of car owners and drivers is growing rapidly. More and more people enjoy the great convenience brought by the expressway. However, the highway is also because of its large flow, fast speed and impact. Li Qiang and other characteristics have also produced a series of traffic accidents. For example, in recent years, traffic jams, road closures, and vehicles caused by traffic accidents caused by insufficient safety sights, excessive speed, vehicle failures, dangerous goods accidents, and low visibility and bad weather such as heavy fog, snow, and heavy rain. Major traffic accidents such as rollovers and multi-vehicle serial collisions are often extremely harmful and have serious consequences. In addition, the general public's awareness of traffic legal system is uneven, the highway auxiliary facilities are imperfect, and the high-speed management work is becoming more and more difficult. At present, relying solely on limited police force and traditional working methods cannot significantly improve the highway order problem.
How to respond quickly and efficiently to emergencies; how to quickly coordinate emergency response with other units and departments to solve problems; how to improve more perfect services; how to maximize the protection of people's lives and property?
A considerable number of expressway management departments have realized that it is necessary to use the new type of collaborative dispatching command system developed by high-tech to improve the existing traffic utilization rate, ease traffic pressure and improve highway management through scientific and information management services. efficacy.
Mazal intelligently combines the current development status, characteristics and actual needs of the expressway, and takes the road traffic informationization as the premise, and uses the self-developed collaborative dispatching command system to provide a high-intelligence, information-based and comprehensive expressway emergency dispatch for the expressway management unit. The command solution provides a variety of communication means such as voice, image, data, and cluster intercom. To achieve "visible, clear, callable, accurate, accurate, and quick response" to ensure that "information collection is fast and accurate, and orders are fast" to provide real-time and accurate on-site conditions for leaders to achieve Remote monitoring, remote command and dispatch, multiple means of communication and processing methods, truly improve rapid response, unified scheduling, and coordinated command capabilities, greatly improving user response speed and processing efficiency for emergencies, and minimizing accident losses.
The expressway coordinated dispatching emergency command platform integrates wired and wireless communication technologies, information technology, IT technology, and sensing technology, based on video surveillance information collection, and uses GIS geographic information system as an auxiliary means to provide audio and video dispatching command platform. It is composed of core and video conferencing, digital recording system, on-duty scheduling system and supporting safety protection system, relevant standards and specifications.
The platform integrates multiple functions such as wired, wireless, mobile, fixed, voice, video and data, and integrates multiple network communication methods to meet the needs of daily duty and handling of public emergencies. When the alarm center receives the emergency report, the command center can accurately, quickly and accurately understand the location of the accident through the auxiliary system such as GIS and wireless video image acquisition. It can know the situation in real time and can be the first time through the graphical dispatching station. Hold emergency audio/video conferences to quickly handle emergencies in the shortest time, minimize accident losses, and ensure the high-speed traffic is carried out in an orderly manner, thus ensuring the speed, accuracy and safety of command and dispatch, and realizing the informationization of emergencies. intelligent control. The command center will become a comprehensive and coordinated command platform for real-time, remote dispatching command and business processing.
Wired scheduling
Through the access gateway, the PSTN telephone can communicate with the PSTN. The graphical dispatching station can perform mixed scheduling on the PSTN fixed-line, private network fixed-line, and intra-system IP dispatching terminals.
Wireless scheduling
By using the wireless interface of the integrated dispatching system, the dispatching station can directly call or hold a mixed meeting with the analog cluster, the regular intercom, the mobile phone, etc., and realize the real-time transmission of the accident scene image back to the command center to help the leader to intuitively decide the command.
The wireless dispatching terminal mainly includes mobile communication terminals such as ordinary mobile phones, PDAs and 3G mobile phones, wireless cluster communication terminals such as vehicle-mounted individual soldiers, hand-held single soldiers, and piggybacked individual soldiers, short-wave communication, satellite communication, and the like. Wireless scheduling mainly realizes unified scheduling of personnel and vehicles moving in position.
The highway cooperative dispatching command platform provides the following functions and services:Multi-functional graphical dispatching station: It adopts user-oriented graphical interface dispatching platform, which is simple, convenient and intuitive to operate. It provides functions such as monitoring, strong insertion, forced demolit, pick-up, transfer, forbidden, multicast, audio and video emergency conference. .
Hierarchical dispatching command: This platform has multi-level dispatching command function to realize hierarchical scheduling.
Emergency plan: When an emergency occurs, the relevant plan can be inquired, and the members of the emergency plan group can click on the group call to hold an audio and video conference to discuss the decision.
On-duty scheduling: docking with the daily duty system of the expressway management unit through the open standard business interface of the system, realizing the recording, processing and query of the shift scheduling information, and displaying the duty information on the big screen.
Electronic address book: The contact information can be inquired through various conditions, and the personnel can be divided into groups according to departments and organizations.
Digital recording: Digital recording of all calls, ensuring that every important link is well documented, such as answering, scheduling, meeting, etc., for voice recording.
Report statistics: information recording and storage of highway emergency processing.
Intelligent alarm: When traffic or high-speed monitoring system detects abnormal conditions, it can realize automatic multi-point voice alarm, voice/video emergency conference, SMS group sending, and email group sending alarm. Enable the staff to grasp the abnormal situation in the first time for timely processing.
Auxiliary decision-making: When an emergency emergencies occur, the auxiliary decision system such as GIS collaborative geographic information and image acquisition system can automatically display the alarm location and the on-site situation feedback to the command center in real time, which can assist the dispatcher in making scheduling decisions.
Mazuo intelligently constructed the highway cooperative dispatching command solution to realize the whole process tracking and support of emergency incident handling: from the reporting of emergencies, the collection of relevant data, the judgment of urgency, real-time communication, linkage command, Emergency site support, leadership assistance decision-making. High-speed information access for any event, any location, 24/7, providing seamless, reliable communications in a secure, fast manner. It enables the emergency response teams to exchange crisis information quickly and accurately, strive for limited manpower and time resources, and save emergency costs. In the shortest time, the people's production and normal life were restored at the fastest speed, and important contributions were made to protect people's lives and property, maintain social stability, and build a harmonious society.
