Wave server constructs a public safety network of metro line Line 4

"Lead" November 2012 a city subway line Line 1 opened operation so far, has become the most important travel vehicles, but with the increasing number of passengers, how to ensure the orderly operation of the subway in the case, to ensure the safety of passengers, but also become the focus of the subway management department. Therefore, in the latest construction of metro line Line 4, a city subway again into the wave company, responsible for the subway police video surveillance, public security computer network system construction work, hope through the tide in the field of public security accumulation of experience, through the information means to maintain the public safety of the subway.

Along with the subway safety incidents, the subway public security has to be worried, but also aroused the Chinese government's strong concern, to protect the subway public safety has become the most concerned about the project. After the opening of a city subway line, the South section of line Line 2 was completed, on November 8, 2013, a city subway line Line 4 also ground-breaking construction.

The subway operates in a relatively small and closed underground space, which is crowded and vulnerable to attack and destruction. How to maintain the stability of Metro public security and improve the rapid deployment and management of public safety through information technology means has become the most important part of the construction of subway projects, and has tested the information system of the Metro Public security departments on prevention, management and control.

Because in the first two period of the subway construction, the tide has been responsible for information construction, so the construction of the Line 4 line, again introduced Wave company, responsible for the subway police video surveillance, public security computer network two systems construction work. Hope that through the tide in the field of public security accumulation of experience, through information means to maintain a city subway line Line 4 public security. Line Line 4, the first phase of the project length of about 20.8km, all for the underground line, set up 18 stations, including 18 command and control center, subway Police monitoring room and all kinds of special rooms.

Subway safety management personnel proposed in the Metro line Line 4 project, video surveillance, computer network system as the core part, accounting for 70%-80%, only on duty on the active monitoring to find problems, it is difficult to achieve rapid deployment, the subway safety management staff hope that from the passive remedial type of the development of proactive predictive security management method, Hope that through the wave of video surveillance system to achieve the warning and prevention of events.

The second brain and the third eye coordinate stability

Public Security Video Surveillance System (CCTV) as the "Third Eye" of line Line 4-mainly by the stations, car park, car, control center, police station, public Security Bureau, such as video surveillance system expansion and access, such as the composition of the rail transit stations for real-time monitoring, in order to timely detect, deter and combat illegal and criminal acts, Provide video forensics for investigation and detection.

The Subway Public Security Administration department takes the subway Public Security Branch Command Center as the main body, the police station, the police stations as the supplementary three level management system. Computer network system through the network with the Municipal Public Security Bureau, so that the first-line office of the subway police personnel can access the network of public security, inquires about the "comprehensive information", quickly judge, check the exact identity of the suspect and related information, real-time login "truthfully filing system", "crackdown on reporting system", "Daily Police Situation", "Public Security bulletin" and other information. The system is mainly composed of office automation system, access police system and video conferencing system, which needs all kinds of video server, data backup and system security Management Server, central server and so on to run. The Subway Public Security Administration Department has made the system the "second brain" of the Public Security Department.

These two systems need a large number of video server, video Analysis server, Management Server, database server, video server, data backup and system security Management Server, central server, etc. to do the system support. The average daily flow of a city subway is 220,000 people, the peak is up to 500,000 traffic, this will produce a lot of information data, the high load processing of the server hardware equipment requirements are extremely harsh. Must satisfy the massive data processing performance request, but also must achieve the RAS characteristic above 99.99% in the stability, the other massive equipment management convenience also needs to consider.

60 four-way server Protection 2 platforms 1800 monitoring points effective management

Over the years, the tide has been serving a city subway, with excellent product strength and quality service, for a city subway line Line 1, line Line 2, and Line 4 line of public safety system construction escort. According to the project target requirement of line Line 4 and the actual use of previous projects, the tide chooses to adopt nearly 60 efficient, stable and independent four-way server nf8560m2 as the hardware support of the system.

As the most important central part of line Line 4, the computer network system must carry tens of thousands of times each day the crime suspect inquiry, the report reorganization, the information information and so on work brings the system pressure, in addition also has to handle from 1800 monitors the network 24 hours at any time uploads the data information to face the data load pressure, all these to the product reliability, Manageability requirements are very high. For these needs of users, the wave provides a four-way rack-type server nf8560m2, using the Intel Xeon E7 high-end processor performance fully meet the requirements, at the same time with the wave of independent research and development design of the Rui Jie management system, can provide the subway safety remote system Monitoring, maintenance, management, control functions, In this way, even if the data System administrator is in the field, the whole system can be managed and maintained in real time through the remote management module.

The monitoring, maintenance and management of the hardware platform of the Metro Public Safety Network system not only has a high requirement for timeliness, but also requires the continuity and integrity of the information, which has a high reliable and stable requirement for the key vulnerable parts of the server. Wave nf8560m2 products key components such as power supply, system fans, hard drives are supported hot plug, especially the power can support the 1+1+1 two-level hot standby, three power supply even if two power supply damage, still have a power supply can ensure the normal operation of equipment. Such a level of redundancy, can make in a single point of failure, without downtime for system maintenance, greatly improve the reliability of the system. Especially in the face of the 24-hour upload video data brought by the data load pressure, support hot-swappable hard drive and fan to the reliable operation of the system is more indispensable to ensure the continuity of the subway public Safety network hardware platform work,

During the construction of line Line 4, the whole wave of cooperation is fully invoked to meet the needs of various projects. On the Line 4 line system and communication equipment environment to the strict standard test platform to build the simulation, after a one-month high pressure stability test, tide nf8560m2 smoothly through the subway special environmental testing, such as moisture-resistant high temperature and so strict requirements.

(Harsh public security communication equipment use environment)

The subway environment is usually more closed, the air circulation is poor, especially in the summer if the temperature is too high or too high humidity, it is easy to produce static electricity led to the motherboard short-circuit, while the subway station will resonate with the ground, easy to reduce the hard disk power supply life, these harsh environment is a wave of nf8560m3 to the great test. The tide provides the solution one is in the computer room to increase the dehumidification equipment, two times to the machine time-sharing operation, in the morning and evening peak and weekend crowd, start all system software, and people, close unnecessary system software, thus reducing the overall temperature of the machine. For Shockproof, in the hard drive carrier, placed a thin but good toughness of the shock pad, so as to effectively resist the subway and the ground resonance.

In addition, the wave also aimed at the subway police Room predictability of the special problems, the customization of services. With the system design side of the line plan, for its reservation space, in the case of the subway special cabinet, taking into account the heat and normal use, specially for a city Subway design short rack-type rail, to free enough space to meet demand. Not only the smooth solution to the problem, while avoiding the adjustment of the line caused by delay and expense, such intimate service is not comparable to other foreign companies.

8 working days to deploy 60 units to meet the management needs of 600,000 people

In a city of metro line Line 4, the first phase of the project, 18 Station Foundation pit, more than 60 equipment, wave only spent 8 working days, fast and efficient implementation of debugging completed. A city subway line Line 4 related responsible person said: "In the time tight task heavy situation, as the manufacturer can such positive response, unlimited provision of a large number of equipment and technical support, to fight is to see the technical strength and strong service team." Believe that in the future of more subway public safety Network system construction, there will be more wave of products and figures. ”
