The most valuable field of application of Internet of Things technology - smart meter reading

In the past few years, communication technology has been the most concerned topic in the Internet of Things industry. Whether it is the current hot LPWAN technology or an evolved version of 5G or existing technologies such as Bluetooth, wifi, and Zigbee, it can attract the attention of the entire industry.

There are several reasons why communication technology is so important:

On the one hand, it is at the core of the Internet of Things (IoT) industry, and it is irreplaceable. It also plays a key role in linking up with others. It can connect sensors and Other Products upwards, and can connect downstream products and industrial applications. Networking business is a very important breakthrough.

On the other hand, communication technology as a basic technology is very important for IoT products and solutions. The homogenization of current hardware product functions is a very common phenomenon. For example, wristband watches and other products have similar functions in the market, but if they can improve on communication technologies, they can support such products to add a wealth of Features.

The Value of Communication Technology for Internet of Things

The application of Internet of Things is very fragmented. Communication technology as a basic technology also needs to be optimized to meet the needs of the Internet of Things. In the following, we analyze the value of the communication technologies that are currently important in IoT applications.

Meter reading

Remote meter reading is one of the most popular Internet of Things applications. Especially in today's society, energy and resources are more and more important. Therefore, we hope to use meters, meters, gas meters and other smart meters, with more accurate data and information to manage users and energy, to provide users with the purpose of efficient use of resources and energy-saving emission reduction.

Traditional meter reading methods face several problems:

Resident users are very scattered and need to invest a lot of manpower to perform on-site meter reading;

The degree of nuisance caused by the meter-reading of households is inconvenient for the residents' lives;

The error of manual meter reading is large and it is easy to measure data inaccurately.

Manual meter reading can not provide accurate data, which is not conducive to the monitoring of the pipeline network, and it is impossible to detect the leakage in time, which may easily lead to poor production and sales.

Users are inconvenient to pay and need long lines;

Water companies and gas companies have a hard time recovering costs;

.......

Therefore, the remote intelligentization of meters through the Internet of Things technology not only facilitates the daily management of public utilities, but also has high economic and social benefits.

Currently, the low-power wide area network technologies represented by NB-IoT and LoRa are very suitable for the meter reading field. If the operator base station covers a dense area, the NB-IoT can be used to make appropriate connections. The use of the LoRa+NB-IoT solution, where the network coverage signal is not so good, can better meet application requirements. In addition, there are also some companies on the market that use the Zigbee+NB-IoT and wired+wireless solutions for corresponding applications according to the actual needs of the project party.

At present, most of the communication module manufacturers in China are involved in meter-reading-related services, among which NB-IoT module manufacturers such as China Mobile Communications, Xinxuntong, and Fangfang Technology all regard meter reading as an important business direction. Xinda, Huaaotong, Anmetong, and Hangzhou Luowan are also deeply involved in the application of LoRa in meter reading.

Security field

Security is a major application market for the Internet of Things, because security is always a basic need of people. In the Internet of Things market, the most important areas of security are video surveillance and smoke alarm monitoring.

Video security Because of the large amount of data to be collected and the low latency, most of the current video surveillance in the city uses a wired connection. For remote areas and mobile object monitoring, 4G and other wireless technologies are required. In the fire alarm application market, there are great differences in application requirements. In this field, communication technologies are required to have long transmission distances, low power consumption, and stable connections. Therefore, technologies such as NB-IoT and LoRa are very suitable.

In the field of security, LongShangTech, XinXinTong, Shanghai PiYuan, BoDa GuangTong, ShengZhe Technology, Delusion Intelligence and other companies have relatively rich products and complete solutions. In addition, the three major domestic operators are also active. The expansion of this application market, driven by operators, security applications are rapidly landing.

Smart City

The smart city is a major infrastructure construction that the country has invested heavily in recent years. Its construction requires the use of various IoT products and technologies. Therefore, the smart city is currently the most important application market for the Internet of Things.

There are many types of projects covered by smart cities, and there are differences in the requirements of each type of application. Therefore, the environmental differences faced by various types of nodes in smart cities are relatively large. For example, the comparison of the physical environment of street lighting, trash cans, and shared bicycles is quite different. Ideally, it is more important for network requirements to focus on lower power consumption and larger connections. Operators' networks such as NB-IoT and eMTC are very suitable for these application scenarios. Scenes such as parking lots, basements, and manhole covers impose higher requirements on the penetration of communication networks. LoRa or LoRa can be used according to the actual needs of the project. The combination of +NB-IoT, of course, requires some additional positioning and management functions, and it needs to integrate RFID, Bluetooth, and other technologies with LPWAN transmission technology.

In the field of smart cities, Huawei, ZTE, MG Smart, Xiamen Jun, Shanghai Mobile, Zero Smart, and many other communications companies have relatively rich application cases.

Car networking

Because of its high added value, high user acceptance, and high market penetration, automobiles have always been a very important application area for electronic information products. The greatest role of IoT communication functions for automobiles is reflected in three aspects:

Remote management of assets;

Video surveillance inside public transport;

Increase the functionality of the car entertainment system.

There are also great differences in the communication technology solutions that need to be used at different levels of car networking. If only asset management of vehicles is adopted, it is more appropriate to adopt GPS+GSM or GPS+NB-IoT solutions. If video monitoring is required, LTE networks are required. The car entertainment system requires LTE networks and future 5G communication technologies.

In the field of car networking, it is also a hotly contested place for all classmates and technology companies, among which communication companies such as Gao Xinxing Wulian, Xinxuntong, U-blox, Telit and Shenzhen Hongdian all regard it as the main business direction.

Industrial area

The huge market volume in the industrial field is also a very important application area of ​​the Internet of Things. The Internet of Things in the industrial field is mainly reflected in three aspects:

Monitor the machinery inside the factory;

Management of plant operators;

Monitor the factory environment.

The more mature monitoring method for industrial equipment is the field bus + wireless transmission method, and the wireless method will be used separately according to the specific needs of the project. The management of the personnel will be managed by means of GPS, RFID, video surveillance, etc. The environment mainly collects information such as temperature and humidity, smoke, etc. Therefore, it is appropriate to adopt LPWAN technology for transmission.

In general, the application scenario of the factory is relatively complex, basically covering the application scenarios of all IoT communication technologies. There are communication companies such as People Networking, Lubangtong, Shanghai Yiyuan and Youfang Science and Technology, which are relatively rich in this field. Product and experience.
