Chapter 1 Product Overview
ASDU-LS Intelligent Gateway adopts industrial-grade NXP Cortex-A7 processor and loads an
embedded Linux real-time multitasking operating system. It supports a variety of communication
protocols and can realize the functions of information transmission, synthesis, editing, management
and monitoring among various devices, such as automation equipment, smart power meters,
intelligent auxiliary equipment of substation and host computer systems. It can be applied in large
and demanding integrated automation system, dispatching automation system and distribution
automation system etc. It is used for information interaction among intelligent electronic equipment,
such as substation microcomputer, and substation host systems to achieve information exchange
between remote power stations and host computer.
ASDU-LS Intelligent Gateway can also be used as the general control sub-station and the front-end
processor of the integrated automation system to form the middle layer of the automatic system. It
can communicate upward with each system such as master station and communicate downward
with the terminal equipment in the area, which achieves the data collection and transmission of the
terminal equipment. Therefore, it can completely replace the microcomputer sub-station or the front-
end processor.
