NB-IoT is very popular, what can it do? [Copy link]

I believe everyone is familiar with the English name NB-IoT, but what exactly can it do? You may be a little confused. Today, let's give some examples of NB-IoT applications in real life.

1. Application of NB-IoT in smart home (smart lock)

With the popularity of the smart home industry in recent years, smart locks are appearing more and more frequently in our lives. Currently, smart locks use non-mechanical keys as a technology to identify user IDs.

Mainstream technologies include: induction cards, fingerprint recognition, password recognition, facial recognition, etc., which greatly improve the security of access control.

However, the above security is based on the premise that the power is on. If the power is off, the smart lock is useless.

In order to improve security, the smart lock needs to have a built-in battery, collect basic data, transmit the data to the server, and automatically alert the user when abnormal data is collected.

Since the smart lock is not easy to disassemble after installation, the smart lock battery is required to have a long service life.

If the door is located in a closed corridor, stronger signal coverage is required to ensure real-time transmission of network data.

There are many smart home terminals, so a sufficient number of connections must be ensured.

The most important thing is that after adding the above functions, the equipment cost can be kept within an acceptable range.

(Applying NB-IoT technology to smart home systems)

1. NB-IoT has the characteristics of low power consumption. It can be on standby for ten years using only two AA batteries, greatly reducing the subsequent maintenance costs.

2. Super strong signal coverage, which can cover indoors and basements, ensuring signal stability.

3. Massive connections to meet the needs of simultaneous connection of multiple terminals in smart homes.

2. Application of NB-IoT in remote meter reading

Water vapor meters are closely related to our lives and are used in every household.

The most primitive method is to manually read meters and collect statistics. With the development of society, manual meter reading has derived various disadvantages:

1. Low efficiency

2. High labor costs

3. Recording data is prone to errors

4. The owner is wary of strangers and will not be able to enter the house

5. Difficulty in maintenance and management, etc.

GPRS remote meter reading came into being. It solves a series of problems of manual meter reading and is more advanced, efficient and safer than manual meter reading.

However, GPRS remote meter reading also has disadvantages that prevent it from being widely promoted:

1. The user capacity of communication base stations is small

2. High power consumption

3. Poor signal

The remote meter reading of NB-IoT technology solves this problem:

1. NB-IoT remote meter reading inherits the GPRS remote meter reading function and also has massive capacity. The communication user capacity of the same base station is 10 times that of GPRS remote meter reading.

2. Lower power consumption. Under the same operating environment conditions, the standby time of the NB-IoT terminal module can be more than ten years.

3. The new technology provides stronger signal coverage (can cover indoors and basements).

4. Lower module cost.

In summary, NB-IoT has great application space in remote meter reading.

3. Application of NB-IoT in fire protection system (smoke detector)

Fires are often reported in the news. Every fire is accompanied by the destruction of homes and the death of people. Every scene is shocking.

Only by raising fire awareness and using fire-fighting equipment properly can we minimize losses and injuries.

The smoke sensor is the sentinel of the fire protection system. It can detect smoke in real time. When the sensor detects that the smoke concentration exceeds the standard, it will send information to the background server and activate related equipment such as alarms and broadcast speakers. The server will automatically push information to relevant personnel and departments to realize intelligent fire safety.

Using NB-IoT can fully meet the requirements:

1. Using NB-IoT wireless smoke detectors can avoid the problem of difficult wiring and greatly save installation costs.

2. NB-IoT has a large number of connections, and the number of smoke detectors connected at the same time can reach more than 100,000, which can meet the needs of connecting a large number of smoke detectors at the same time.

3. NB-IoT has ultra-low power consumption and can work for ten years in standby mode, greatly reducing the maintenance cost after installation.

4. NB-IoT has super strong signal coverage, which can cover indoors and basements.

4. Application of NB-IoT in manhole cover monitoring

Our city is under rapid construction, and with the increase in underground projects of municipal public infrastructure, the increase in manhole covers is inevitable.

Manhole covers play a huge role. If the status information of manhole covers cannot be obtained in time, it may cause great losses to people’s lives and property.

At present, most cities use manual inspection methods to manage manhole covers. However, the number of manhole covers is huge, and the efficiency of manual inspection is limited. It is often impossible to obtain manhole cover status information in a timely and accurate manner, which leads to various safety hazards.

The theft or destruction of manhole covers will not only directly cause loss of public property, but may also cause irreparable personal injury and economic losses to nearby pedestrians and vehicles.

By using NB-IoT to locate, monitor and manage manhole covers, you can get timely information on the status of the manhole covers, and use the NB-IoT network to send an alarm to the server to notify management personnel when the manhole cover is moved or damaged, thereby minimizing damage and losses.

Advantages of using NB-IoT technology for manhole cover monitoring:

1. No more manual inspections are needed, and all data is automatically transmitted to the platform, saving a lot of human resources. 2. The communication base station user capacity that NB-IoT can accommodate is 10 times that of GPRS, which can meet the huge demand for manhole covers.

3. NB-IoT has ultra-low power consumption, and the normal communication and standby currents are at the mA and uA levels. The module standby time can be up to ten years, which greatly simplifies the later maintenance of manhole cover monitoring.

4. NB-IoT has stronger and wider signal coverage, which can cover indoors and basements, truly achieving full coverage in manhole cover monitoring.

5. NB-IoT technology breaks through the bottleneck of GPRS technology and will surely shine in the wireless communication industry in the future.

5. Application of NB-IoT in street light monitoring

But there are huge shortcomings hidden under this gorgeous appearance:

1. Energy waste: As the city enters the second half of the night, people have begun to rest and the flow of people on the street begins to decrease. Some areas do not need too much street lighting at special times, resulting in energy waste and unnecessary cost increase;

2. Difficult maintenance: Due to the use of manual inspection, a large amount of manpower is required, and the number of street lights is huge. The real-time status of street lights cannot be obtained in time, resulting in extremely low efficiency in street light fault maintenance and troubleshooting.

The monitoring center is the center for the operation, maintenance, processing, statistics, analysis and supervision of the entire street light monitoring system. It centralizes data management and monitoring, and implements operations such as target locking and quick search. It can also customize control strategies to control the street lights on both sides of the road to be fully lit, fully turned off, and lit at intervals in different time periods.

Tianwang Interconnect is a professional Internet of Things company in China that has the ability to develop a complete set of systems for smart hardware, cloud platforms, and mobile applications, focusing on the research and development and production of Internet of Things products. It was the first to launch a full set of smart terminal solutions in China, including NB-IoT smart locks, NB-IoT public version solutions, 4G door locks, GPRS door locks, and CAT 1 door locks. NB-IoT smart lock landing project: In February 2019, China Mobile completed the introduction of NB-IoT smart lock products, and NBIoT smart lock projects have been launched in batches in Shenzhen, Guangdong, Kunming, Yunnan, Changsha, Hunan, Nanning, Guangxi, and Nanjing, Jiangsu. Each project includes a smart door lock developed based on narrowband Internet of Things (NB-IoT) communication technology, supplemented by a supporting rental management platform, Internet of Things device management platform, and mobile APP and mini-programs.

NB-IoT can play the following roles:

1. The NB-IoT wireless network can realize distributed remote control of the monitoring center.

2. Street light fault detection function, actively reporting the location of faulty street lights through NB-IoT.

3. NB-IoT has a large communication capacity, so there is no need to worry about too many or too dense street lights causing individuals to be unable to communicate.
