What technologies does logistics information technology include?

According to the functions and characteristics of logistics, logistics information technology includes computer technology, network technology, information classification and coding technology, bar code technology, radio frequency identification technology, electronic data exchange technology, global positioning system (GPS), geographic information system (GIS) and so on.

1. Bar code technology

Bar code technology is an automatic identification technology which is produced and developed in the practice of computer application. It provides us with a way to identify and describe the goods in logistics.

2.EDI technology

EDI refers to the use of computer networks to transmit and exchange structured data through electronic means and standardized formats. The three elements of EDI system are EDI software and hardware, communication network and data standardization.

3. Radio frequency technology

Radio frequency identification technology is a non-contact automatic identification technology, which automatically identifies the target object through radio frequency signals and obtains relevant data. The identification work can work in various harsh environments without human intervention.

4.GIS technology

Geographic information system is the product of many disciplines. Based on geospatial data, it provides all kinds of spatial and dynamic geographic information in time by using geographic model analysis method. It is a computer technology system for geographical research and geographical decision-making.

5.GPS technology

Global Positioning System (GPS) has the ability of real-time three-dimensional navigation and positioning in the sea, land and air. In the field of logistics, GPS can be applied to automatic positioning, tracking and dispatching, railway transportation management and military logistics.

Extended data:

Logistics information technology is an important symbol of logistics modernization and the fastest developing field of logistics technology. From bar code system used for data acquisition to microcomputer and Internet in office automation system, various terminal devices and computer software are developing with each passing day.

At the same time, with the continuous development of logistics information technology, a series of new logistics concepts and new logistics management methods have emerged, which has promoted the reform of logistics.

In supply chain management, the development of logistics information technology has also changed the way for enterprises to gain competitive advantage by applying supply chain management. Successful enterprises support their business strategy and choose their business by applying information technology. Using information technology can improve the efficiency of supply chain activities and enhance the management decision-making ability of the whole supply chain.

In China, various logistics information application technologies have been widely used in all aspects of logistics activities, which have had a far-reaching impact on the logistics activities of enterprises.

1 magnetic stripe technology: magnetic stripe (card) technology bonds a thin layer of directionally arranged iron oxide particles with resin in the form of paint, and sticks it to a non-magnetic substrate such as paper or plastic. A magnetic stripe is essentially the same as a magnetic tape or disk used in a computer. It can be used to record letters, characters and numerical information.

The advantage is that data can be read and written many times, and the data storage capacity can meet most requirements. Because of its strong adhesion, the device is widely used in many fields, such as credit cards, bank ATM cards, air tickets, bus tickets, ticketing cards, membership cards and so on. However, the anti-theft performance and storage capacity of magnetic stripe cards are far behind some new technologies, such as chip card technology.

Speech recognition technology: it is a technology that converts speech into text information through recognition. Its biggest feature is that it doesn't need to input information manually, and it is especially suitable for those who have to use their hands and feet to collect information or whose keyboard typing ability is not high.

However, the biggest problem of speech recognition is the recognition rate, so it is difficult to apply it continuously and efficiently. It is more suitable for occasions where phonetic symbols are used repeatedly.

Visual recognition technology: Visual recognition system is a distinctive image analysis and recognition system, which can collect limited information of symbols, characters, numbers and other image contents.

The application obstacle of visual recognition technology is also the recognition rate of some irregular or unclear images, and the data format is limited, so contact scanners are usually used for scanning. With the development of automation, vision technology will develop in a more precise and professional direction, and will be combined with other automatic identification technologies.
