A Group Of Intelligent Devices To Net Using Infrared Technology And Field Bus

As the embedded technology becomes more and more popular, various intelligent devices are provided with the function of embedding network,for the sake of implementation of remote monitoring.These devices include industrial equipments,medical equipments,electrical home appliances and some mobile devices(such as bus).Generally,the intelligent equipments in certain extent are gathered,then they are made connecting to network,finally remote monitoring is realized.The main contribution of this paper is give as follows:1.A interface circuit is designed which uses single-chip computer as main controller,SJA1000 as CAN bus controller,and PCA82C250 as the CAN bus driver.It is used connecting intelligent equipment to CAN bus, which realizes cluster.Base on it,the communication technique of the optical media is increased this method is provided with innovation.2.This system also realizes hardware connection between embedded Micro-processing chip SPCE061A and network chip RTL8019AS, transplants real-time embedded operating systemμC/OS-II to SPCE061A so that embedded systems can deal with real-time multi-tasking,transplants TCP/IP in order to complete function of network transfer so that the cluster system can input or output data through the network.3.Give an instance of implementing plan above,which is applied to public transport systems.The research in this paper is practical guide about the development and application of intelligent devices in network using the technique of wireless media.
