Exploring the charm of Nanjing's intelligent Traffic: cloud computing Achievements Eagle Eye

Another Monday morning, Zhang as usual tidy up, 8 points, and his wife, daughter on time to go out. Sit in the car, fasten the seat belt, Zhang take out the mobile phone, inquire what. One side of the wife slightly nervously looking at the Zhang, the car Zhang expression easy to put down the phone, start the vehicle, said: "Nothing, all the way is green." ”

To the Magnolia Road, Zhang first 4-year-old daughter Xiao Xi into the Nanjing Bamboo Garden Kindergarten. More than 20 minutes later, he also sent his wife to the newspaper building in the middle of Lung Pan road. Zhang look at the time, just the past half an hour, 9 points to the company no problem.

Can send away after the wife, in just entered Zhongshan East Road, Zhang in front of a car accident occurred. From the scene of the car accident, there should not be too much casualties. In the Zhang still annoyed and delay for a long time to traffic police to ease the transportation, some traffic police have come to the scene. Quickly pull over the accident vehicle and divert the vehicle behind it. Although the accident delayed some kung fu, but Zhang still at 8 o ' clock 50 on time to their work units located in Shanxi Road, the Galaxy building.

Zhang, a general citizen who lives and works in Nanjing, has to go through mornings like this in the morning, sending his wife and daughter to his unit and school. Although in the early rush hour, need to send three people on time to have the pressure, but for Zhang, these are not difficult. Because now out of the door, through the days of Yicheng navigation client verified when the road conditions, adjust their travel routes, and in the event of car accidents, traffic police response speed has been faster than their own direct alarm is much quicker.

This is now Nanjing, an office worker early peak travel not too much worry Nanjing. This is also the charm of Nanjing Wisdom. Behind this intelligent traffic is strong it technology and a stable system. A few days ago, reporters also visited the Nanjing Intercity online Information Technology Co., Ltd., which carries out the construction of the information service system of Jiangsu, and the police, and has a detailed understanding of the service provided by the Nanjing public in the service center. And from the bottom of the system to provide the basic technology of the Nanjing Cloud Storage Technology Co., Ltd., the relevant experts to learn more about the project's "hero"-Intel and Nanjing Cloud to create a cooperative development of data Cube cloud computing integrated machine-operation.

High-speed processing allows the card mouth, camera, such as Eagle Eye

One into the inter-city online Jiangsu, patrol Information Service System service center, the eyes are the three left in the right screen, and about the screen is divided into 9 small screen respectively, which shows Nanjing City and the surrounding areas such as Suzhou, Changzhou, such as the main trunk road traffic situation. And the middle of the screen shows the Nanjing Xin Jie Kou traffic situation, and the corresponding dimensions show the traffic lights, the length of the car queue.

At present, Jiangsu Traffic and patrol Information Service center mainly includes five major systems, that is, video to see transportation control system, real-time road information, SMS issuance system, traffic police control system and high-speed road conditions system. Among them, the real-time road condition system, is refers to on the map to be able to display the red, the yellow, the green three kinds of colors intuitively to show a city road The pass state (red indicates the congestion, the yellow indicates the congestion, the Green Express is unimpeded). And this state, Nanjing residents can be through the mobile phone terminal inquiries, the current Nanjing residents and Zhang like, in front of the first query traffic, and then choose whether to travel.

And the previous article mentioned Zhang met the accident, the traffic police reaction speed why so fast? Cloud creators of experts to answer. In Jiangsu Traffic and patrol information This service system, inter-city online responsible for the platform and large-scale construction, and Cloud Chong is responsible for the bottom of the cloud computing platform and intelligent transportation in the field of transport video analysis.

Traffic police response speed, not a car accident scene someone to the police, but based on the cloud platform, the Traffic management department can be very clear to know which road accident occurred, congestion and so on. "Intelligent traffic, through automatic analysis of video, can be completely proactive analysis of these videos, active alarm." When a road accident occurs, the system will automatically remind the corresponding personnel. "Cloud creators related experts to introduce, based on the rapid computing ability of cloud platform, through the corresponding model, such as a car in a certain section of the time too long to determine whether the accident occurred, and the system for automatic alarm, so that many of the original passive information directly into active understanding, inform and solve the problem.

Because of the powerful data processing capability of cloud computing, the vehicle license plate information taken by many cards is aggregated to a cloud platform, and the speed of the information of a certain license plate is realized from the past few minutes to now 00 seconds. Previously can only query a certain local area of the card to shoot the license information, is now the city or even the province's information query speed as fast.

This is a lot easier to solve when it comes to solving the problem of a licensed vehicle. Or to inquire about vehicles suspected of crime, in the province to take data, not as before need to look for data from various databases, now cloud platform for a few seconds to query the car all information.

Using cloud computing's powerful processing power, coupled with cameras all over the city's intersection, will play a big role in improving traffic congestion. In addition to timely notification to the public of real-time road conditions, car accidents and so on, in a number of details are also reflected. such as traffic lights at the junction of the street, traffic queues, such as to a certain extent, will form an early warning, so as not to cause congestion.

Because of cloud computing, the camera, the card mouth really like Eagle Eye is generally monitoring the city's traffic situation in every corner.

Eagle eyes behind the data Cube cloud computing All-in-one Machine

In the past, all the camera and card data in Nanjing are in the traditional database, but it will take a long time to extract and query. To achieve intelligent traffic, you must have the ability to quickly and access the data extracted. This will refer to the system's "hero" Data Cube cloud computing machine.

The Data Cube cloud computing All-in-one is a new cloud computing database developed by Intel and the cloud, mainly run on the new family of Intel E5 Server, the formation of 2 meters high rack, a rack, 18 servers, processing capacity on all servers are balanced, the data are completely balanced scattered across the nodes.

Data from previous databases can still be read, cloud creators related experts said: "We are not to completely replace the original relational database, because it maintains a complex relationship, we suggest or stay in the original system, only when it can not handle the data, such as massive traffic, a large number of meter data, We suggest a separate cloud computing process. ”

At present, the Nanjing City has nearly 1000 cameras, because the number of high-definition, SD, and so on, the daily amount of data in hundreds of T, and Data Cube cloud computing one of the biggest advantage is large data, massive data real-time processing.

According to the introduction, Data Cube cloud computing machine can be in storage, data processing to achieve such high performance, but also based on hardware and software in two aspects of cooperation. At present, Intel provides E5 new hardware, happier than the previous server hardware 80%, at the same time it is hot and high-temperature hardware, also has a good performance in energy saving. The software level, the All-in-one machine needs a lot of support, which is the cloud storage, which is the cloud created by the Cstor cloud system under the support of the implementation. On top of the storage system, you build a very fast distributed database.

In many areas are mentioned will use cloud computing, but for Nanjing City, it is confident that their city's traffic behind the real cloud computing: All traffic, security camera data on a platform, these massive data to real-time processing, the need for a large number of computers. At the same time, the allocation of these to all nodes, and in the process, some nodes failure, the system can shield the failure, and continue to provide services.

Because of the "eagle Eye" all over the city, because of cloud computing, the ancient city of Nanjing in the preservation of its own unique cultural background, but also added a because of the wisdom brought about by technology.
