How does the "running and maintenance" system of urban intelligent transportation show its power?

Over the years, the state and the government have attached great importance to the development of the transportation industry. With the continuous expansion of the scale of intelligent transportation construction and the continuous application of it, it has brought new challenges to the operation and maintenance of intelligent transportation systems.
How to keep abreast of the operation of the intelligent transportation system and ensure long-term stable and reliable operation of large-scale intelligent transportation systems, and to put the systems that have been built and put into operation into good management, maintenance, and use, and to prevent and control smart traffic and respond to emergencies. China has played a greater role in further investing its benefits and digging deeper into its application value, which has become an important issue before us.
The entire life cycle of an information system, "operation and maintenance" is the longest period in the life cycle, and it is also the stage where the system really exerts its use value. It is confined to the narrow sense and ignores the generalized stage, which will result in a discount to the system's use value. .
I. Construction content
The construction of the urban intelligent transportation operation and maintenance center will closely integrate the actual situation of the construction of the intelligent transportation system, and build a comprehensive and comprehensive local characteristics with three aspects: operation and maintenance service center site construction, operation and maintenance management tools, and operation support system. The intelligent operation and maintenance service center realizes the following contents:
1. Transform the isolated and decentralized operation and maintenance management model into a centralized management model;
2. Through the intelligent operation and maintenance management tool, adopt the high-efficiency mode of “Science and Technology Management Technology” to achieve the passive and active service requirements;
3, to achieve a complete system of norms, clear responsibilities, clear division of labor, meticulous and thoughtful and innovative management model.
Second, the overall structure
The system is divided into five levels, namely, the monitoring resource layer, the network bearing layer, the operation and maintenance platform layer, the operation and maintenance center layer, the application center layer, the national ministry-related technical standards, the unified construction standards and interface requirements, and the network security support. Data security supports the entire system.
Third, the solution
Through the operation and maintenance service center site construction, operation and maintenance management tools, operation and protection systems, build a comprehensive, comprehensive and intelligent operation and maintenance service center with local characteristics.
First, the operation and maintenance center construction.
Construction and maintenance service center office, equipped with computers, servers, large screen displays, matrix, audio and video acquisition equipment and other necessary hardware, access to operation and maintenance management tools, and build an online operation and maintenance management operating platform to achieve an operation and maintenance management Concentrate, maintain efficient and efficient, advanced scientific and technological means, complete and standardized system, clear responsibility, clear division of labor, and meticulous and meticulous visualization of the intelligent operation and maintenance service center.
Demonstrated the large-scale visualization of the operation and maintenance service center. After the completion of the operation, the company can provide large-screen visualization and decision-making services based on operation and maintenance of big data, providing a basis for leadership decisions.
The operation and maintenance center’s office space is based on the basic environment construction and mainly includes the following parts: TV wall display system; integrated control matrix; check-in terminal and supporting office system; client system
Second, operation and maintenance management tools.
According to the ITSS thoughts of the operation and maintenance tool software, integrating cloud computing, Internet of Things, big data, machine vision in one, using standardized interfaces to achieve multi-system interconnection. The centralized monitoring center subsystem, the maintenance process management center subsystem, and the assessment assessment and billing center subsystem cover the entire operation and maintenance business management.
According to the software architecture diagram of the operation and maintenance tool designed by ITSS, the hierarchical structure of the system is demonstrated from the bottom of equipment resource layer, transport layer, integrated access layer, service support layer, and application layer.
The system can be deployed on an independent server or deployed on the cloud. According to different authorities and responsibilities, the construction unit, construction unit, supervision unit, and operation and maintenance unit provide comprehensive application functions. The platform software can operate on the PC as well as on the mobile terminals.
Third, run a security system.
On the one hand, it is an organizational guarantee requirement.
In order to maintain the standby status of the operation and maintenance service center, it is necessary to establish an organizational team with actual combat capabilities according to the scale of the operation and maintenance service center, and establish a highly operational duty management system.
Operation and maintenance service center seat configuration: It is required to configure the operation and maintenance management personnel according to the scale of the operation and maintenance service center, and scientifically arrange on-duty service according to the Interim Provisions for the Service Support Level of the Public Security Information and Communications Department to ensure the smooth flow of information and communication at any time and with high quality. ;
Quality requirements for operation and maintenance managers: O&M managers must have appropriate technical qualifications. Technical training should be conducted before taking up jobs. During the daily operation, emergency plan drills should be conducted to enable them to reach the preparation level.
Management system requirements: To establish an on-site management personnel on-duty management system and supervision and evaluation system, management software, manual spot checks and other methods should be used for supervision and assessment.
On the other hand is the operational guarantee requirements. In order to allow the operation and maintenance managers to master the normal operation of each system function in real time, a set of operation inspection management system should be established and supervised and evaluated.
Inspection system: The operation and maintenance personnel shall adopt manual/periodic manual inspection, and ensure the normal operation of the operation and maintenance service center through the combination of manual inspection and network management platform;
System operation log: The system operation log should be established. The operation and maintenance management personnel should coordinate and feedback the system failure and warranty;
On-duty report requirements: A report reporting mechanism should be established, historical data should be collected, system operation trends must be discovered in a timely manner, and system fault warning should be performed.
Emergency protection mechanism: emergency plans should be established, emergency drills should be regularly organized, and technical contests can be conducted to improve technical support capabilities.
There are also maintenance requirements. In order to ensure the normal operation of the operation and maintenance service center, it is necessary to establish a daily maintenance and maintenance management system, configure the necessary spare parts, and even establish a redundant system. Maintenance and maintenance of the system should be completed after the supervision and assessment of maintenance work. After major repairs, technical experts should be organized to perform inspections.
Fourth, development prospects.
With the advancement of science, the vigorous development of computers and network technologies, the attention given by management departments to operation and maintenance management, and the government’s promotion of purchasing services, the project construction and operation and maintenance management will gradually separate, with complete intelligence. The operation and maintenance system will be applied in the process of system operation and will mainly develop in three aspects:
The first is to develop in the direction of professional intelligent operation and maintenance management, establish a special operation and maintenance monitoring service center, a sound operation and maintenance mechanism, a professional maintenance team, a complete operation and maintenance assessment performance management, and ultimately form a complete operation and maintenance system. As the scale of construction continues to expand, the importance of management will become more and more important.
The second is to make full use of scientific and technological means, adopt advanced O&M management tools, conduct effective whole-process management of equipment operation and even the entire life cycle of the equipment, evaluate the performance of the equipment's construction and operation results, and provide for future monitoring and resource construction. Powerful basis.
The third is to make full use of the operation and maintenance of big data (ie, data-driven) to provide early warning of system operation failures, and provide means for judging and judging the faults correctly. At the same time, it effectively evaluates the operation of each project and system, and optimizes them in a timely manner. Deal with and effectively improve the effective utilization of monitoring resources and safeguard measures.
