The invention discloses an intelligent communication controller based on an ARM (Advanced RISC Machines) technology, and in particular relates to an intellectualized interconnected communication controller which can meet the conventional major communication modes: a TCP/IP (Transmission Control Protocol/Internet Protocol) Ethernet, a MODBUS (Macro-block Mode for B-blocks) industrial communication standard protocol, a PROFIBUS (Process Field Bus) industrial communication standard protocol and a CAN (Controller Area Network) bus communication protocol, belonging to the technical field of communication. The intelligent communication controller takes an ARM-7 chip as a core processor and is provided with configurations such as an Ethernet MAC (Media Access Control) communication processor, an asynchronous communication processor, a CAN communication processor, a timer, a counter, an AD (Analog to Digital) converter and the like; and a UCOS/II (Uprange Computer Output System/II) embedded operating system is adopted for a hardware part, and good interconnection and conversion functions are realized in various communication modes by using the perfect real-time multi-task and multi-thread management function of the operating system. The intelligent communication controller has the advantages of high programming flexibility, high response speed, low bit error rate, high communication efficiency and compatibility with a plurality of mainstream communication modes.
