A traditional one-to-one monitoring systems is usually used in the automatic production system, which is designed for small-scale industry. The network type monitoring system is applicable for cross-factory or cross-country automatic production system design for large-scale industry. In comparison, the distributed monitoring system is applied in a large scope, multi-connection monitoring environment to monitor the data retrieving modules distributed in different positions. In theory or in practical use, the Client/Server distributed monitoring system is more efficient than the Host monitoring mode. In spite that it would be theoretically feasible by implementing such structure on the Internet-based distributed monitoring system, it would however be impossible for the front section of remote unit to transmit back the real-time monitoring and data in physical application. Under the restriction of limited bandwidth, the multi-point distributed monitoring would be a challenge to the modern multi-layer network structure for transmitting a larger flow of image monitoring. In order to improve this defect by applying the traditional multi-layer network structure on the limited bandwidth monitoring, this article proposes the design technology by incorporating a load-balance type of network structure with ActiveX object for the front-section user to carry out real-time monitoring of weight, temperature, and gas sensing and rear-section database retrieving. In this respect, the proposed front-section embedded monitoring module shall include the weight, temperature, PLC controller, and gas sensing monitoring modules as well as the TCP/IP communication program and load-balance modules. To study the effect of employing the mobile communication equipment in the monitoring system, this article proposes the front-section mobile communication equipment platform having an embedded J2ME (Java 2 Micro Edition) structure in which the MIDP (Mobile Information Device Profile) application program is used to develop the TCP/IP front-section program and monitor the drive program. Furthermore, such TCP/IP front-section program will also be used to link the middle-layer IntraWeb Server for structuring these two kinds of integrated network systems that feature different communication properties.The load-balancing monitoring system design for integrating mobile communication is able to improve the shortcomings that result from the multi-layer network monitoring system in the aspect of network bandwidth restriction, but can also help industry effectively enhance the efficiency of monitoring software installation during factory expansion and construction while significantly reducing hardware and maintenance investment costs.關聯 TANET 2005 台灣網際網路研討會論文集
