"There are 1 apples left in the fridge, do you need to order?" "Your phone received a message from the fridge. No reply, according to the pre-set settings, the refrigerator will automatically to the online mall under the order, and prompted you to pay online with your mobile phone.

May 21, in Hebei Unicom Intelligent City Experience Hall, staff Yin Fang to reporters to show the wisdom of smart home appliances, such as the future use of intelligent city.

Our province Shijiazhuang, Qinhuangdao and other 6 regional cities, has been listed as the first national intelligent City pilot. Up to now, 11 municipalities in our province have signed the strategic cooperation agreement with the Internet operators in the intelligent city.

Feel the impending footsteps of the city of wisdom, perhaps the world will change for it. "The city is intelligent, change the embellish and silent." "Hebei Unicom product Operations Support Center deputy General Manager Cai explained that such a future, is the use of advanced development concept of urban planning and design, with integrated technology to solve a variety of urban diseases of the new life."

So, what kind of wisdom supports the construction of intelligent city? "Internet of things, big data, cloud computing." "Cai explains, like a tripod, intelligent city based on these three technologies, the integration of the real world and the digital world is established to realize the perception, control and intelligent service of people and objects.

Internet of Things--

Forming a network of people and objects, objects and objects, realizing informatization, remote management control and Intellectualization

How does the fridge perceive the number of apples? How does the phone control the fridge? Refrigerators, mobile phones, courier companies, how to establish contact? The answer is: Internet of things.

The internet has brought about profound changes in our life, however, the network function, the network world again strong also is virtual, and the real world is separated.

The Internet of things allows people to connect with things, things and things. "Cai Introduction, the Internet is the use of communication technologies such as sensors, controllers, personnel and objects, through a new way together to achieve information, remote management control and intelligent network."

"This is inseparable from sensors and embedded systems. Cai said, "If the Internet of things to the human body, the sensor is equivalent to the human eye skin and other senses; the embedded system is the human brain, responsible for handling information from the sensory nervous system and releasing instructions. ”

As ' the senses ' of the object, the sensor makes the object ' live '. "Cai said," Sensors are divided into heat-sensitive, photosensitive, gas-sensitive types, can perceive sound, temperature, displacement, speed, gravity, light and other physical changes, but also can perceive acid, alkali, salt concentration and other chemical and biological changes. ”

In fact, such as GPS locator, two-dimensional code, supermarket commodity bar code, sensors in the life has been widely used. Cai said that in automated production, sensors are used to monitor various production parameters, and in environmental protection, various sensors can monitor water quality. "It is no exaggeration to say that almost every modern project, from space to the ocean, is inseparable from a variety of sensors." ”

The information acquisition needs the sensor, the information processing, the object remote control needs the embedded system.

Cai Introduction, embedded system is a control panel, but integrated computer hardware and software, integrated circuits, electronic applications and many other technologies. "A variety of programs are embedded, and can be based on the data obtained from the sensor network, through the set up a good program to achieve the entire control logic." ”

In our side, embedded in the water meter, electricity meter, can replace the artificial, realize remote meter reading of the special controller, embedded in the light bulb, according to the light intensity automatically adjust the brightness of the lamp controller; Cai said, small to courier Hand Pad (PDA), large to aerospace satellite systems, are embedded system applications.

Through the sensor equipment to various buildings, home appliances, highways, power grids, water supply systems, oil and gas pipelines and other entities, real-time collection of information, through the embedded system docking received information analysis and processing, the release of remote control instructions. This is the process of the internet of things.

"The Internet of Things" is the cornerstone of the city's wisdom construction, is the foundation of Intelligent City application. The technology accumulation in the key field of IoT determines the quality of the city's intelligent construction. "Cai said.

Hui in the data--

Establishing mathematical tools and data models, filtering data and finally realizing intelligent decision

The sensor readings on the factory machine, the video of the monitoring probe ... Staggering amounts of data, rolling in.

"Take Shijiazhuang as an example, at present the city has installed more than 60,000 public security monitoring probes, the amount of data per day will reach PB-Class (1PB=1024TB)." At present, China in 600 cities equipped with 2000多万个 camera, 365 days 24 hours monitoring, data volume is staggering. "Hebei Unicom communication technology expert Chen Zanqiang said.

But the figures are only one tip of the iceberg. The internet age, especially social networks, E-commerce, mobile communications has brought human society into a large data age.

According to Victor, author of The Big Data Age, 2013, the world's data can reach about 1.2 kilobytes. A digital movie can be compressed into 1GB, while an AI byte is equivalent to 1 billion GB, a chak Byte = 1024 bytes.

Although the data is massive, the data is not rubbish. Data mining and analysis can create huge social and economic benefits.

"The biggest contribution of big data to smarter cities is intelligent decision-making based on predictive function." "Chen Zanqiang said that from the hospital medical data, can analyze the early stage of infectious disease, from micro-BO micro-letter content, can find a certain tendency group ... It's all about the use of big data.

Technicians filter data by establishing mathematical tools and data models. On this basis, according to the different data uses in the intelligent city, put forward the scientific inference method, construct the forecast system of the city operation, and finally realize the intelligent decision.

The analysis and excavation of large data can change human life in the subtle place.

By analyzing and dealing with traffic data such as vehicle flow over the years, the pipeline department can predict the time and place of congestion in advance, and provide important predictive reference for the timely early warning and the evacuation traffic pressure.

"Large data analysis can even help reduce the incidence of crime," he said. Chen Zanqiang said that through the socialization and predictive analysis of historical cases, crime trends and crime patterns could be found, common ground and relevance could be identified, and the relevant departments could be provided with reference.

Sometimes, the way big data is used can be subtle and subtle. For example, the uninterrupted record of each user's clicks on the page, through the analysis of these data can optimize their content and Web page structure, tracking user Weibo "status updates" and "preferences" can design the best ads to earn revenue ...

"Large data mining can not only become a source of corporate competitiveness, but also become a part of national competitiveness." Chen Zanqiang that data is becoming a huge economic asset, a new century of "minerals" and "oil". "The challenges of education, transportation and environmental protection in the modern world are likely to be resolved in the future through innovative means such as large data," he said. ”

Where the clouds are deep

Provide a unified operational support platform to jointly provide supercomputing capabilities and storage space

The explosion of large data growth, the cloud computing data center emerged.

"Traditional computing power and storage space cannot handle such massive and irregular unstructured data." "This needs to be adapted to the data platform for large data analysis," Cai said.

The salient feature of cloud computing data Center is the large amount of basic hardware and software resources. Currently in the field of personal application of the most prominent is "private cloud", such as Baidu Cloud storage, thunder cloud on demand.

Applications run somewhere in the cloud, and users do not need to know where to run. Cai explains: "Through cluster applications, computing power and storage capacity are distributed on a large number of distributed computers, rather than on local computers, these decentralized capabilities are aggregated through application systems, providing a unified operational support platform for providing supercomputing capabilities and storage space." ”

Cloud computing enables users to obtain application services in any location using a variety of terminals. Yin Fang that the resources requested by the individual are "cloud" rather than fixed tangible entities. "Users need only one monitor, one client, they can access the data center through the network to gain computing power and storage space." ”

Intelligent cities urgently need such a powerful information processing system.

"Depending on the virtualization architecture of the cloud computing platform, whether it is government or business, there is no need to build computer rooms and physical servers alone." "Cai said.

In the intelligent city, through the integration of transportation, medical, taxation, water conservancy and other government resources, the establishment of a public cloud computing data center, can break the city's functional system of the original fragmentation, eliminate the duplication of resources, improve resource utilization, to achieve information sharing.

Up to now, 11 regional cities have deployed large-scale cloud computing data centers. Has built China Unicom Langfang Cloud Base, to provide more than 40,000 cloud computing racks, call center 7,500 seats, for the intelligent city of Hebei province and public government cloud provides a reliable guarantee.

In addition to allowing you to experience 10 trillion of computing power per second, cloud computing can also provide virtualization and on-demand billing services.

"Simply put, computing power, storage capacity will become a commodity, like hydropower, easy access, on-demand billing, low cost." Yin Fang said, "Cloud" is a huge pool of resources, you want to use the cloud resources, you can open a separate faucet, how much water you use, how much charge.

"The intelligent city will eventually form a platform, the overall technical framework of the two major technical systems." Cai said that the Intelligent City Integrated management platform based on large data mining and analysis, the data acquisition system based on IoT and the cross regional resource allocation system based on cloud computing.
