Forth, this paper takes use of CPLD auxiliary control circuit,the LCD screen and keyboard to achieve local man-machine interface control.The remote monitoring of sensor network nodes is realized by the compilation of PC monitoring software which takes VC++ as the software development platform.To verify the success of transplantation on uC/OS-Ⅱreal-time operating system and the realization of multi-task system,we have done a full experiment. By taking a large number of experiments,we also verify the correctness of the protocol conversion(CAN-TCP/IP) gateway function and traffic status information acquisition function.Finally,through the local LCD screen and a remote PC monitor interface,we get the experimental results.The sensor network nodes developed by this issue meet the design requirements and expectations,provide a reference for the further study of distributed monitoring system.
