Abstract: A design scheme of intelligent embedded nodes based on μCLinux is given aiming at the on-site network requirements of current automation and control systems in this paper, which adopts 32-bit embedded ARM microprocessor and embedded real-time operating system to realize the detection and control of field data. The system has general Ethernet interface to improve the remote data transmission speed. Under the premise that guarantees the reliability of the control tasks to be completed, every node in system realizes multi-channel data acquisition and control and has the function of network monitoring to keep node test and control integrated in LAN, thereby the security and timeliness of automatic control of equipments are increased and the requirements of integration and advanced for information control are meet. The system has good application prospects in application.
Keywords: embedded System; μCLinux ; Ethernet node
