[New concept of instrument network in China] A year ago, if we refer to the Internet of Things, everyone's impression may still remain at the conceptual stage. Because at that time, there were no clear understandings such as "What is the networking between things and things?" "What kind of application scenarios are realized?" However, in less than a year in recent times, the Internet of Things has come to the people of Ningbo, Zhejiang, with lightning.

In May of this year, the narrow-band Internet of Things basic network NB-IOT has covered the whole city; the daily use of electricity meters, water meters, charging piles, telephone poles are all equipped with communication modules; and the production equipment in the factory can already communicate with each other. . I believe in the near future, "letting every sand have its own IP address" will no longer be a joke.
Internet of Things basic network has covered the whole city
People talk to people. The sound is transmitted through the air to the other person's ear. People and people call and the signal is transmitted over the air through the mobile network. In the Internet of Things, dialogues between things and things also require a medium. At present, the network recognized by the world as being the most stable and suitable for the Internet of Things is called narrow-band Internet of Things, and its English and Ningbo are quite fatal, called NB-IOT. In May this year, the NB-IOT network has achieved citywide coverage in Ningbo.
According to Li Haidong, assistant general manager of China Telecom Ningbo Manufacturing and Internet Integration Center, NB-IOT is similar to the original 2G communication. The difference is that 2G is a communication protocol based on communication between people and is suitable for real-time calls, while NB- IOT is the communication method of communication between objects and things.
"To use this kind of network, we need a communications chip. Just like we have a mobile phone, we can access the Internet to talk and access the Internet," said Li Haidong.
Relevant person in charge of China Telecom Ningbo Branch also revealed to reporters that in June, some of China Telecom’s mobile phone call frequency bands will also use NB-IOT communication, which will make call quality more stable. In addition, the future of car networking, driverless can not be separated from NB-IOT.
Water meters have communication capabilities
With the basic network, a large number of application products have also entered the lives of the general public.
It is understood that the nation’s first NB-IOT smart water meter produced by Ningbo Water Meter Co., Ltd. has settled in Ningbo Yaojiang Garden District in June this year after it was first launched in Shenzhen. At present, 80 intelligent water meters have been connected to Ningbo's smart water system. The network service module is provided by Telecom and Unicom, and the chips are manufactured by Huawei.
According to Qin Wei, director of the office of the Ningbo Water Meter Company, the average leakage rate of tap water in China is now about 20%, and the direct economic losses caused by leakage losses exceed 10 billion yuan each year. If we can stop damages in time, even if it is a percentage drop, we will not only save money, but it will also become an increasingly precious water resource. The intelligent water meter installed with the IoT communication module can not only remotely read the meter, fail alarm, but also have a large flow alarm function. Once there are problems such as pipeline rupture, water leakage, etc., the smart water meter will immediately report to the control system to provide the specific location of the fault. The water company can stop the water supply and repair according to the information in time to prevent the waste of water resources.
Not only water meters, including gas meters produced by Ningbo water meters, but also electric meters and heat meters produced by Samsung Oaks will be equipped with communication modules.
Recently, Ningbo Xinshengzhong Piezoelectric Co., Ltd. has also launched two new applications based on the Internet of Things. One of the “electric stewards†connected the distribution facilities with the Internet of Things and added a large number of sensing devices. In this way, real-time monitoring of all distribution facilities in the city can be realized, equipment and equipment can be analyzed from various types of data, and fault early warning and real-time operation and maintenance can be implemented to ensure the safety and efficiency of electricity consumption for enterprises and households.
Another "Yi-Yi-Charging" charging station with an Internet of Things module can be shared. Consumers can buy the charging post and install it. After installation, they can connect it to the Internet. When they do not use the charging post, they can open it to other owners and charge it. cost.
Industrial Internet of Things flourished, with 3 billion Swords worth 30 billion yuan
In Ningbo's industrial sector, the intelligent manufacturing ecosystem centered on the Internet of Things technology is also rapidly building.
In the sneakers flying weaving model factory built by the Cixing Group, the styles on footwear orders can be modeled by computers. These data are like a common language between machines. Through the control layer, production tasks are sent to each With the use of 3D flying weaving technology, the Taiwan Feida knitting machine uses a shoe's upper to be molded in seconds.
“We currently sell 180,000 sets of intelligent knitting machines in the world. The next step will be to provide an overall intelligent solution based on customer requirements. Then we will introduce various types of raw material suppliers and integrate them into a unified cloud platform. Li Lijun, chairman of the Cixing robot, said.
In order to further develop the internet of things industry in Ningbo, at the end of May this year, the Ningbo Internet of Things Industrial Park officially settled in Jiangbei. The industrial park will introduce a large number of upstream and downstream enterprises such as sensors, core components and software integrators around the Internet of Things technology. At the same time, the "Ningbo City Industrial Internet of Things Action Plan for Three Years" was officially issued in June. The goal is to achieve a breakthrough in the main business income of Ningbo's industrial IoT industry by more than 30 billion yuan in three years. Ningbo will accelerate its advancement into the national industry. The Internet of Things benchmarking city.
According to Chen Bingrong, director of the Municipal Economic and Information Commission, Ningbo's industrial IoT industry has a certain foundation, with about 130 companies, and the production value in 2016 is about 17 billion yuan.
“Ningbo City Industrial Internet is still in its early stages of exploration. It has a small number of companies and is mainly concentrated in the low end of the value chain. The total scale is too small. Industrial clusters have not yet been formed and the industrial chain needs to be further extended. We must base ourselves on the basics, seize the three major areas of sensors, transmission networks, and integration services to create industrial chains and industrial support.†Chen Bingrong said that there are huge business opportunities behind the Internet of Things, such as data transmission and storage services, the Internet of things platform, and data analysis. Services, etc., Emerging market opportunities abound, depending on whether we can seize the opportunity to nurture new industries, new formats, and new models.
