Application of NB-IoT in animal husbandry
Animal husbandry is mainly divided into captivity and stocking, and the northern and western frontiers of China are the main grazing areas.
The advantage of stocking is that the quality of livestock meat is high, and the cost of feed is reduced, but it is followed by many inconveniences in livestock management.
Artificial grazing is the most primitive and direct method, but artificial grazing has some drawbacks:
Manual stocking requires special stocking and waste of manpower
Manual stocking has safety hazards and is at risk of being attacked by wild animals
Manual stocking is not good for systematic management
With the advancement of science and technology, scientific breeding will surely become the trend of future development. The GPS+GPRS animal husbandry positioning system can solve this problem.
However, the size of the cattle and flocks is huge, the capacity of the GPRS communication base station will be insufficient, and the battery life will be problematic. Moreover, the farms are relatively remote, and the signal coverage intensity will be problematic, which may result in data being untransferable...
The birth of NB-IoT technology perfectly solves a series of problems:
NB-IoT can accommodate the communication base station user capacity is 10 times that of GPRS.
NB-IoT has ultra-low power consumption, normal communication and standby current are mA and uA level, module standby time can be up to ten years, no need to replace the battery from birth to slaughter, reducing the workload of workers.
NB-IoT has stronger and wider signal coverage, realizing the normal transmission of data in remote areas.
NB-IoT technology truly breaks through the bottleneck of GPRS technology. This technology has emerged as the times require, and truly realizes the ideas of livestock farmers. In the huge animal husbandry, it must shine.
Application of NB-IoT in remote meter reading

The remote meter reading of NB-IoT technology solves this problem;
NB-IoT remote meter reading also inherits the GPRS remote meter reading function and also has a large capacity. The same base station communication user capacity is 10 times that of GPRS remote meter reading.
Lower power consumption, NB-IoT terminal module standby time can be more than ten years under the same operating environment
New technology signal coverage is stronger (can cover indoors and basements)
Lower module costs, the expected single connection module does not exceed $1, and will be lower in the future. In summary, NB-IoT technology is the product of the development of the new era, solving many problems of previous limitations. The future IoT industry will definitely belong to nb-iot, realize everyone's interconnection, and all things interconnect.
Application of NB-IoT in manhole cover monitoring
Our city is undergoing rapid construction. The underground engineering of the municipal public foundation is increasing. The increase of the manhole cover is inevitable. The manhole cover has a huge effect. If the manhole cover status information cannot be obtained in time, it will likely cause extreme damage to people's lives and property. Big loss. At present, most cities are managed by manual inspections, but the number of manhole covers is huge, and the efficiency of manual inspection is limited. It is often impossible to obtain the status information of the manhole cover in time and accurately, resulting in various safety hazards.
Whether the cover of the manhole cover was destroyed
The theft or destruction of the manhole cover not only directly causes the loss of public property, but also may cause irreparable personal injury and economic loss to nearby pedestrians and vehicles.
How to eliminate these safety hazards has become a top priority. Using NB-IoT to monitor and manage the manhole cover, you can grasp the status information of the manhole cover in time, and use the NB-IoT network to send alarms to the server to notify the management personnel when the manhole cover is moved or destroyed. Avoid damage and loss.
Advantages of manhole cover monitoring using NB-IoT technology
No manual inspection is required, and all data is automatically transmitted to the platform, saving a lot of human resources.
NB-IoT can accommodate the communication base station user capacity is 10 times that of GPRS, which can meet the huge demand for the number of manhole covers.
The NB-IoT has ultra-low power consumption. The normal communication and standby currents are mA and uA. The module standby time can be as long as ten years, which greatly simplifies the maintenance of the manhole cover in the later stage.
NB-IoT has a stronger, wider signal that can be used to cover indoors and basements, enabling true coverage in manhole cover monitoring.
NB-IoT technology breaks through the bottleneck of GPRS technology and will definitely shine in the wireless communication industry in the future.
NB-IoT application in smart home (smart lock)
With the popularity of the smart home industry in recent years, the frequency of smart locks appearing in life is getting higher and higher. At present, smart locks use non-mechanical keys as the technology for user identification ID.
The mainstream technologies include proximity card, fingerprint recognition, password recognition, face recognition, etc., which greatly improve the security of the access control, but the premise of the above security is the power-on state.
If the smart lock is in the power-off state, it will be ineffective.
In order to improve security, you need
Smart lock has built-in battery
Collect basic data
Transfer data to the server
Collecting abnormal data automatically alerts the user
Because 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 in a closed corridor, a stronger signal coverage is needed to ensure real-time transmission of network data; the number of smart home terminals must be sufficient. The number of connections; the most important thing is to ensure that the equipment cost is controlled within an acceptable range after adding the above functions.
Application of NB-IoT technology to smart home systems
NB-IoT features low power consumption and can be used for up to ten years with only two AA batteries, greatly reducing post-maintenance costs.
Super signal coverage, covering the indoor and basement, ensures signal stability.
A large number of connections to meet the simultaneous connection of multiple terminals in the smart home.
At a low cost, a single NB-IoT chip costs less than $1.
NB-IoT for street light monitoring
When night falls, various, colorful street lights in the city light up.
Putting a beautiful coat on the city, there are huge shortcomings hidden under this beautiful appearance.
Energy waste
Since the night of the city enters the middle of the night, people have begun to rest, and the flow of people on the street has begun to decrease. In some areas, there is no need for excessive street lighting at special times, resulting in wasted energy and increased unnecessary costs.
Maintenance difficulties
Due to the use of manual inspection, a large amount of manpower is required, and the number of street lamps is large, and the real-time status of the street lamps cannot be obtained in time, resulting in extremely low maintenance and troubleshooting efficiency of the street lamps.

NB-IoT application in fire protection system (smoke detector)
There are often fires in news reports.
Every fire is accompanied by a broken family.
Every scene is shocking.
We must improve fire protection awareness and use fire fighting equipment in a reasonable manner to minimize losses and injuries.
The smoke sensor is the sentinel of the fire protection system, which can detect smoke in real time. The sensor detects that the smoke concentration is excessive, sends a message to the background server, and activates the alarm bell.
For broadcast speakers and other related equipment, the server will automatically push information to relevant personnel and departments to achieve intelligent fire safety.
In practical applications, according to fire protection requirements, the installation of smoke detectors is densely distributed, which is inconvenient to route and costly.
The use of NB-IoT wireless smoke detector can avoid the problem of difficult wiring, which greatly saves installation costs;
NB-IoT has a huge number of connections, and the number of smoke detectors that can be connected can reach more than 100,000, which can meet the simultaneous access of a large number of smoke detectors;
NB-IoT has ultra-low power consumption and can operate for ten years in standby mode, greatly reducing maintenance costs after installation;
NB-IoT has super-signal coverage and can cover indoors and basements;
NB-IoT is ultra-low cost, and the chip is estimated to be as low as $1.
NB-IoT is applied to asset location tracking system
With the in-depth development of information technology and various intelligent terminal devices, the demand for personnel and asset positioning will continue to heat up. The application of location services also presents fragmentation features such as asset inventory in smart campuses, medical waste tracking, and pet positioning. . .
Today, most of the trackers on the market are based on GSM, and power consumption is a big problem. Large chip area, high cost, relatively low coverage, etc., this technology happens to be contrary to the needs of the location tracker. The GSM technology is quite backward, resulting in poor product experience of the location tracker. In some countries, GSM has been retired or is facing network retreat, resulting in a shortage of such products and technologies.
The birth of NB-IoT technology and its birth with low power consumption and deep coverage properties make up for the shortcomings of traditional communication technology. This can be used to locate assets tracking whether it is in an indoor or outdoor area. NB-IoT technology, its low power consumption, wide coverage, low cost, small size and other characteristics make it an indispensable communication method in the field of asset tracking.
