Application of Internet of Things Technology in Logistics

毕竟都是相互关联的,应用on of Internet of Things technology will fundamentally change the way of production in society, improve people's quality of life, and promote the construction of intelligent cities. As an important core infrastructure of the city, the intelligent logistics system is the lifeline for ensuring the normal operation of the city, and will be rapidly upgraded under the transformation of Internet of Things technology and applications. Considering that the implementation process of intelligent logistics requires different types of IoT technologies to support, from the perspective of perceived execution level, network transmission level to application service level, different types of Internet of Things technologies play a targeted role in the construction of intelligent logistics systems.

First, the perception layer technology is the pioneering technology of the Internet of Things. Objects can only be discovered and interacted by being perceived. The application of the sensory layer technology enables the IoT system to quickly identify target objects in the logistics process. The sensing layer often uses smart label technology, machine vision technology, global positioning system, regional high-precision positioning technology to complete the perception and tracking of objects.

First of all, the use of massive wireless sensors can obtain item status and logistics information in real time, ensuring the authenticity and completeness of remote monitoring information in the background, and can play a huge role in logistics warehouse management and item distribution.

Second, IoT terminals allow logistics managers to monitor the status and location of goods in real time. In the process of tracking the goods, the monitoring personnel can fully understand the distribution speed and the status of the goods in the first time, optimize the transportation routes in a targeted manner, improve the transportation efficiency, and abnormal conditions that may occur (such as the temperature change of the goods in the cold chain). ) Make an urgent response.

Logistics Information Interoperability Sharing Technology and Application National Engineering Laboratory Research believes that with the development of Internet of Things technology, the size of intelligent terminals is getting smaller and smaller, and the power consumption is getting lower and lower, smart tag technology is one of the most important technologies in the field of Internet of Things. It can automatically identify and mark the items in the logistics process and establish a complete digital file.

After the marked items, the complete information of the full cycle will be saved by the smart tag and automatically acquired by the reading device, providing data support for the logistics supply chain management. The technology can be effectively applied to multiple scenarios such as real-time monitoring of goods and transportation vehicles, intelligent scheduling of goods, and intelligent warehouse management of products.

Second, the network transmission layer related technology is an essential element for the realization of the interconnection of all things. Intelligent logistics has systemic and networked features, and must be based on network conditions and communication technologies for information transfer and data processing. Considering that the network of large-scale logistics enterprises covers the whole country and even overseas, the Internet of Things needs to rely on the relevant technologies of the network transmission layer to realize long-distance effective management of logistics.

The existing communication technology is facing the massive connection demand of the Internet of Things, and is developing towards low power consumption and wide coverage. Low-power wide-area LPWAN technology is currently a hot spot. The development of NB-IoT, eMTC, and 5G mobile communication technologies has laid a solid foundation for the low-power, high-performance Internet of Things. NB-IoT is a base station multiplexed cellular network that supports low-power devices in the WAN cellular data connection. It can be deployed directly on GSM networks, UMTS networks or LTE networks. It has fast speed, low cost, low power consumption and coverage. Wide range of features.

The Internet of Things platform based on NB-IoT technology can help logistics enterprises realize information coordination and control in transportation, warehousing, distribution, loading and unloading, packaging, distribution processing, information management and multiple work scenarios, and improve operational efficiency and productivity.

Third, the application service layer enables the Internet of Things technology to fall into various sub-segments to achieve service functions for the masses. For example, in order to share logistics resources and improve resource utilization, the logistics industry can realize the collection, processing and interconnection of information by creating a public service information platform, thereby effectively optimizing resource allocation.

The platform can be built on the basis of collating, analyzing and processing the public information of logistics and transportation, breaking the bottlenecks of many industries including information monopoly and information island, thereby optimizing the traditional logistics system, improving the logistics service level and improving logistics. The level of informationization of activities provides important technical application support for the transformation and upgrading of the logistics industry.

Secondly, the intelligent IoT terminal can effectively improve the voice and image processing capabilities of the logistics system, and help managers achieve efficient use of hardware and software facilities. Coordination and coordination between different systems to achieve interoperability and interaction between different logistics systems.
