Embodiment Construction

[0028] Below in conjunction with accompanying drawing and embodiment the present invention will be further described

[0029] A kind of intelligent communication controller based on ARM technology of the present invention (as attached figure 1 shown), including:

[0030] The network transformer is used for isolation, so that the Ethernet physical layer can adapt to various PHY chips, and can prevent damage caused by static electricity and lightning.

[0031] Using a suitable PHY chip to communicate with the MAC communication controller is a key part of the hardware design. In the wiring process, special attention should be paid to the distance between TX+ / TX- and RX+ / RX- not exceeding 2mm, and the distance between two pairs of lines should exceed 3mm. The circular arc routing can make the communication function achieve a better effect.

[0032] During hardware design, it is necessary to conduct repeated experiments on the size and position of each terminal resistor in order...

Abstract

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.

Description

technical field [0001] The present invention relates to the technical field of communication, specifically referring to an embedded ARM processor, an embedded real-time operating system UCOS / II and TCP / IP communication protocol analysis, MODBUS communication protocol analysis, PROFIBUS communication chip configuration and protocol analysis, and CAN communication protocol analysis, Compatible with multiple mainstream communication methods, good interconnection and conversion functions. Background technique [0002] In the existing technology, MODBUS, PROFIBUS, and CAN are still the main communication methods of many control equipment and signal acquisition equipment, while Ethernet has fast communication speed, low bit error rate, convenient configuration of communication equipment, and general PC can be used It has become a very popular communication method to realize this function through the network port without adding special conversion equipment. Therefore, the above-me...
