Application And Analysis Of Internet Of Things In Warehousing And Logistics

1, introduction

The development of information technology centered on the Internet of things is known as the third information technology revolution. Since 2010, the Chinese government has attached great importance to the development of the Internet of things. A series of industrial policies and plans for the development of the Internet of things have been promulgated, and the Internet of things has risen to a national strategy.

We believe that the development of the Internet of things is not a sudden change, but a gradual process of deepening the integration of the whole network from the aspects of automatic information extraction, information integration, local networking of goods, intelligent service and control of local system.

The idea of the Internet of things was first put forward based on RFID/EPC technology. Later, the idea of the Internet of things was promoted and improved with the breakthrough of various perceptual technologies and network technologies.

When the technology of Internet of things was first put forward in the world in 1999, the logistics industry was placed high hopes. Because of its core position in the logistics industry, the warehousing industry launched the exploration of the Internet of things technology for the first time in RFID/EPC.

From the end of 2003, China's warehousing industry began to explore the application of IOT technology based on RFID/EPC. In 2004, -2006 also experienced a hype of Internet of things applications.

At present, RFID and other IOT technologies have many successful cases in the warehousing industry, but most of them are limited to intelligent warehouse management and automation operation.

2, the main Internet of things technology applied in warehousing industry

The Internet of things is the "Internet of things". It is an intelligent network system that realizes the intelligent identification, location, tracking, monitoring and management of the Internet through various sensor devices, RFID technology, video recognition technology, infrared sensing, global positioning system, laser scanner and other information sensing devices.

The Internet of things mainly has three levels of structure: the perception layer, the network layer and the application layer. According to the Internet of things architecture, the Internet of things has three major technical systems, one is the perception technology system, the two is the communication and network technology system, and the three is the intelligent technology system.

The most commonly used Internet of things perception technologies in warehousing industry are RFID technology, GPS technology, sensor technology, video recognition and monitoring technology, laser technology, infrared technology, Bluetooth technology and so on. In the Internet of things technology, the core technology of the Internet of things is often using the network technology directly connected to the internal LAN of the enterprise, leaving the interface with the expansion of the Internet and wireless network.

3. Application of Internet of things in warehousing industry

Application of sensing technology:

According to Hua Xia

In ordinary warehousing systems, besides the most widely used technologies, such as bar code automatic identification, "electronic label assistant picking system" is also widely used.

The so-called electronic tag is not a RFID tag, but a system that uses electronic indicator labels to pick up jobs.

With this system, the order of the warehousing order is decomposed by computer system, pmitted to the shelves, and the auxiliary picking system is displayed by electronic means.

This system is simple, practical and widely applied.

In the past two years, wireless network technology has been adopted to pmit picking data, and no field wiring is needed to build the system, which greatly facilitates the application of technology.

In advanced warehousing and distribution systems, the automatic delivery and sorting system also uses laser, infrared and other technologies to perceive, locate and count items, and make full automatic quick sorting.

In addition, in order to visualize warehouse operation and implement video surveillance in warehouse, a video perception monitoring system has been adopted in some warehousing systems, and good results have been achieved.

In 2010, a system based on auxiliary voice picking was also applied in China.

This system is decomposed by the warehouse information system to store orders, forming voice prompt information. With the help of wireless network and earphones worn on the picking staff, the picking order is sent to the picking clerk to complete the picking operation.

In addition, with the development of Internet of things technology, in 2010, the food logistics center in Wuxi and the garlic cold storage base in the Jining Internet of things used the sensor technology of temperature and humidity to integrate sensor technology and other sensing technologies, and to perceive physical information such as temperature and humidity in real time, so that the sensing technology could be further applied.

Application of intelligent storage network and pmission technology

The biggest trend of modern logistics is networking and intellectualization.

In manufacturing enterprises, modern warehousing and distribution centers are often combined with enterprise production systems. Warehousing systems as part of production systems play a very important role in enterprise production management.

The network architecture of enterprise internal system is always an independent network system built by internal LAN.

Logistics companies face a wide range of logistics networks. The information management of warehousing and networking is often combined with the Internet system and the enterprise LAN.

Logistics centers and stores and distribution points

Information pmission is often aided by Internet technology.

Since 2010, WLAN technology has also been widely applied in the storage industry Internet of things system.

Intelligent warehouse operation and control technology

According to the statistical analysis of relevant data, the intelligent terminal technology of storage industry includes robotics, RF handheld terminals, voice prompts terminals, video surveillance terminals, unmanned vehicles and so on.

With these technologies, the automatic handling of items, automatic stacking and stamping of robots, automatic identification of items, and intelligent manual picking are realized.

In the intelligent warehouse management and control system, the combination of Internet of things technology and WMS technology has achieved warehousing, intellectualization and automation.

There are not many intelligent control and management of logistics process. The Internet of things and logistics informatization still remain in general applications such as automatic identification, automatic perception, automatic positioning, process tracing, online tracing and online scheduling.

The application of intelligent management technology, such as expert system, data mining, network convergence and information sharing optimization, intelligent scheduling and line automation adjustment and management, still has a big gap.

At present, only in the enterprise logistics system, part of the logistics system can also be combined with the enterprise production management system seamlessly, intelligent operation; in some fully intelligent and automated logistics center, the logistics information system can be fully automated and intelligent logistics operation.
