With the advent of the fourth global industrial revolution, high and new technologies such as Internet of things, sensors and information processing systems have been applied in the field of port logistics. In order to comply with this trend, some countries are gradually developing and applying intelligent port technology in the port industry. The construction of intelligent port will help to enhance the comprehensive strength of the port. At the same time, it will bring great improvement to the control of logistics cost and the overall efficiency of logistics. Starting from the development process of the port, this paper introduces the relevant concepts and structures of the intelligent port, and then expounds the development status of the intelligent port at home and abroad by reading relevant materials. According to the concept and research content of the intelligent port, this paper focuses on the analysis of the functions and characteristics of the intelligent port, and introduces the opportunities and challenges faced by the intelligent port, so as to provide reference for the future development of the intelligent port To provide the right basis for the healthy development of the port.
