Abstract


This article by intelligent sensors embedded systems technology , CAN bus technology , design a CAN bus interface , you can complete the image data , the temperature and humidity of the real-time data acquisition and transmission , and the formation of an intelligent sensor network system . Smart sensor network with video surveillance , acquisition and data of temperature and humidity intelligent analysis of the role of the CAN bus intelligent sensor network node , and the host computer is connected to sub - network system , and further each host computer and the monitoring center Ethernet server networking which constitute the overall intelligent network system can effectively meet the widely distributed and dispersed nodes distributed acquisition and real-time monitoring . A low-cost , low-power , miniaturized , multifunctional intelligent nodes to build a full-featured , low-cost multimedia intelligent sensor networks . Relative to the existing smart sensor an important breakthrough point , this paper, the design of smart sensor , smart sensor image data can be collected and limited network bandwidth , CAN bus to transmit image data . From the content of this article can be divided into three parts: the first part is mainly based on the overall design of the CAN bus intelligent sensor network system . Statement of this topic based on CAN bus structure, function , and network characteristics to the overall design of the system of intelligent sensor network works , introduced last program on the processor and network interface for intelligent sensor network node , select . The second part is the hardware design of intelligent sensor nodes . Smart sensors , power module , data acquisition module , data processing module and network interface module , the design of smart sensor hardware modules were described in detail, and gives specific hardware circuit design schematic diagram , concluded PCB design and debugging on experience . The third part of intelligent sensors embedded LINUX - based software design . Software design involves the establishment of the embedded Linux system , and then based on the Linux 2.6 kernel , smart sensor CAN controller and the temperature and humidity sensor drive design , final design on the application of intelligent sensors to achieve its function is described in detail .
