Nowadays, with the rapid development of communication technology, the communication industry is about to enter the 5G era. Data transmission will be more intensive, and the amount of data exchange will become larger and larger. Especially for M2M communication, because the deployment range of equipment is generally wider, and wireless equipment must avoid frequent battery replacement, LoRaWAN technology was born, and it shines in the field of Internet of Things applications.
First, the service life will be a great advantage. In the era of conforming to the Internet of Things, frequent battery replacement of IoT devices needs to be avoided. Frequent battery replacement is more troublesome, which requires the equipment to be able to achieve a long battery life. And LoRaWAN has a very good performance in terms of battery performance. Taking water meter application as an example, LoRaWAN can provide a service life of up to ten years, which basically meets the application scenarios of water meters.
In the second aspect, long-distance transmission has to be mentioned. Looking at the past wireless transmission technology, in many cases it is a short-distance transmission, including WiFi, the transmission distance ranges from a few meters to a few hundred meters. It is different now. For future IoT devices, frequent deployment of device nodes will increase costs under different environmental applications. The LoRaWAN technology can support a transmission distance of tens of kilometers, and the architecture is very simple, which reduces the equipment cost and use cost of the network to a certain extent.
In the third aspect, flexible network construction can be completed. Mr. Kenny Pai also said that LoRaWAN can support not only private networks but also public networks, which is entirely up to the user or operator. Judging from the current development situation, LoRaWAN technology is increasingly used in multiple vertical markets, and solutions are becoming more and more complete.
Fourth, it has constituted a complete ecosystem. For a standard, the most important thing is not a single device, but a complete ecological architecture resume. Now, with more and more manufacturers and the market participating in LoRaWAN technology, LoRaWAN network has formed a very large coverage in the world, and can also provide a very complete solution for users to adopt.
Mr. Kenny Pai also emphasized, “To be precise, LoRaWAN is a product of LoRa. Based on this product, we hope to establish a standard to provide a common platform for product use, communication and information exchange.
Smart agriculture
For agriculture, low-power and low-cost sensors are urgently needed. The application of sensors such as temperature, humidity, carbon dioxide, and salinity is of great significance for agriculture to increase yields and reduce water consumption. These data indicators will not change significantly in a short time, and the amount of data is small and requires real-time performance. Not high, so LoRaWAN is undoubtedly the best choice.
Smart building
For the renovation of the building, sensors such as temperature and humidity, safety, harmful gas, and water flow monitoring are added, and the monitored information is uploaded regularly, which facilitates the supervision of managers and also makes users more convenient. Generally speaking, the communication of these sensors does not need to be particularly frequent or to ensure a particularly good quality of service. At the same time, a portable home gateway can meet the needs, so LoRaWAN is a more suitable choice in this scenario.
Automated manufacturing
In the automated industrial production environment, a large number of intelligent technologies are applied, and various information and data are converged in the network. Therefore, the characteristics of the selected network are directly related to the execution quality of the production plan. Some scenarios require frequent communication and ensure good quality of service (QoS). At this time, NB-IoT is a more suitable choice; while some scenarios require low-cost sensors with low-power and long-life batteries to track equipment and monitor Status, LoRaWAN is a reasonable choice at this time.
Smart logistics
The geographical scope of the logistics industry is very broad, so the first choice when choosing a network is low investment and long working life. In order to be able to track the pallets and determine the location and status of the goods, what the freight company needs is that the facilities involved in the entire logistics process are under the network coverage, so not only the network nodes are required to be economical enough for large-scale installation, but also have the flexibility to make it It can be installed on a transportation vehicle as a mobile gateway. In this way, the NB-IoT technology that needs to rely on 4G base station network deployment obviously cannot meet this requirement, and LoRaWAN's low cost, high battery life, high mobility, and the stability of communication during high-speed movement make it unique in the field of intelligent logistics. Lead the way.
Stator and rotor laminations are an important part of motors and generators. The stator and rotor laminations are made of electrical steel by cutting and stamping. Usually the laminations are circular, and for those large motors or generators, the laminations are fan-shaped. Usually the thickness of the stator and rotor laminations is 0.2mm, 0.35mm, 0.5mm, 0.65mm, but depending on the application, there are thinner or thicker laminations. We are able to produce motors of various sizes from 100mm to 1250mm outer diameter. For larger motors or generators, we can also produce stator segment laminations.
