Description
Technical Field
The invention relates to the technical field of material management, in particular to an intelligent material monitoring and management technology based on an NB-IOT (network b IoT) technology, a pressure sensor technology and a temperature and humidity sensor technology.
Background
New IoT connections are all industrial internet of things (IIoT) solutions, requiring low power wide area network (LPWA) technology to provide efficient connections, ubiquitous coverage, and competitive service payment models for low bandwidth solutions. Industrial internet of things applications may also require seamless coverage in remote environments where maintaining a connection at all times consumes power and shortens the life of the solution, which if on site can run for ten years or more. Narrowband internet of things (NB-IoT) technology is a promising solution.
Narrowband internet of things (NB-IoT) is a new wireless technology standardized by 3GPP in 2016. It rises rapidly as LPWA technology, supports a large number of novel industrial internet of things IIoT devices, including intelligent parking lots, utilities, wearable devices, and industrial solutions. This is because it can efficiently connect large device groups, each NB-IoT network cellular base station can support up to 5 million devices, while greatly reducing power consumption and covering areas that cannot be reached by traditional cellular technologies.
NB-IoT greatly improves network efficiency and can support a large number of new connections using only a portion of the available spectrum. The high network efficiency of NB-IoT also greatly reduces power consumption, allowing battery life to exceed 10 years. In addition, the NB-IoT may penetrate deep underground and into enclosed spaces, providing 20+ dB indoor coverage.
NB-IoT infrastructure technology is less complex than traditional cellular modules, simplifying OEM design, development and deployment. At the same time, it provides the same reliable and true security and privacy functions as LTE mobile networks, including support for user identity confidentiality, entity identity verification, data integrity and mobile device identification.
The NB-IoT has obvious advantages in the application of the Internet of things, and is incomparable with the traditional cellular network technology and short-distance transmission technologies such as Bluetooth and Wi-Fi. Firstly, the coverage is wider, the NB-IOT has 20dB gain compared with the existing network under the same frequency band, and the coverage area is enlarged by 100 times.
Secondly, the support capability of massive connection is realized, and 10 ten thousand connections can be supported by one sector of NB-IOT. Currently, there are about 500 ten thousand physical sites around the world, and assuming NB-IOT is deployed completely and three sectors are provided for each site, the number of accessible internet of things terminals is 4500 hundred million.
Meanwhile, the power consumption of the NB-IOT is lower, namely 1/10 at 2G, and the standby time of the terminal module can be as long as 10 years. Will also be lower in cost, with module costs expected to fall within $ 5. With the scale effect and the technical evolution brought by market development in the future, the power consumption and the cost are expected to be further reduced.
Furthermore, in terms of supporting big data, the data collected by the NB-IoT connection can be uploaded directly to the cloud, while bluetooth, Wi-Fi, etc. technologies do not have such convenience.
There are various types of mounds in factories, construction sites, etc., such as: jade, coal pile, waste material, garbage and other materials with irregular shapes and sizes. These mounds also need to be handled by the manager.
However, the following difficulties mainly exist in the management of the stacking materials (especially, the logistics, transportation, metering, inventory management and the like related to the bulk materials) through investigation:
1. the occupied area of the piled objects is larger, and the occupied area is increased along with the stacking of the objects;
2. in general, a manager registers and records materials entering and exiting, but does not monitor the existing total material warehouse and verify the consistency of the quantity of the materials entering and exiting;
3. the place of piling is generally abominable, and is difficult to supply power in the open air, and some piling such as: coal and the like are not easy to be electrified for avoiding fire monitoring equipment;
4. the places where the objects are piled up generally bring certain difficulties to network construction and data transmission outdoors;
5. the place where the piled materials are generally outdoors, so that great challenges are brought to security work;
6. some of the piled materials are inflammable materials (such as chemical raw materials) and the temperature of the piled materials needs to be monitored, so that fire hazard is prevented, and unnecessary economic loss is avoided;
7. some of the piled materials need to be moisture-proof, so that humidity needs to be monitored and early-warned.
Monitoring and supervision of the condition of a masonry is extremely important in many areas.
