Equipment Remote Management System Analysis And Design,

The rapid development of the emerging technology such as the computer technology, the communication technology and so on in recent years, has promoted the various fields moving towards automation and information, thus speeding up the adjustment and promotion of industrial structure. Traditional remote management system demands a mass of manpower to complete most of the work. Therefore the operational status of the equipment can't be acquired in time which resulting in high production cost and low efficiency. It's not adapted to the developmental tendency of information.In this thesis, a new communication mode combined with Ethernet and GPRS is used to build a remote management system to the present situation. This new communication mode can chose different communication mode to complete the remote management depending on different problem which has extended applications of the system.In the first chapter the meaning and background of this paper are introuduced briefly as well as the developing situation. In the following chapters the general design concept, terminal hardware design, software design are accomplished respectively. Finally, the testing and debugging of the system are done.In the hardware design, Micro-controller unit is designed with the ARM microcontroller LPC2378 as its core. The chip with isolation technique is used to design three functional interfaces of RS-232, RS-485 and CAN which are used for acquiring service data. At the end, the communication modules of GPRS and Ethernet are designed. In the software design, the analysis and design of the remote terminal, the communication protocols and the remote management center based on the concept of functional decomposition and modularization are completed.This system can realize the transmission of the service data, handle and store service data. The fault warning function will work when the equipment is out of work. Also the warning information and controll information can be sent to control and manage the remote terminal. According to the remote management, it can effectively achieve not only the preventative maintenance of the equipment but also less the probability of unusual condition and improve the operating efficiency of equipment.The testing of the Ethernet communication and the GPRS communication was done respectively in laboratory. The testing results indicate that the system is reliable with good function. The desired objective is accomplished.
