Design And Implementation Of A Man-machine Interface For The Embedded System MMB2004

The development of computer technology, communication technology and network technology, has promoted the development of embedded system. Because an embedded system has conspicuous characteristic of small, strong performance, low power dissipation, high dependability and face to application, it has already widely applied to extensive fields such as the military security department, household appliances, network communication, industry control.The combination of the embedded system and communication technology will enormously strengthen the intelligence and flexibility of the network, greatly enhance the communication functions, and realize the interconnection among various kinds of communication systems. Fieldbus control system is a representative embedded system. Fieldbus is a correspondence network which connects with the bottom equipments or instruments in process control and manufacturings automation, it's also a integration of modern correspondence network and control system. With the continuous development of the fieldbus, it is easy to sample and deal with the signals, but how can we set up a information platform through which we can rectify the status of the system and interferewith it? That's exactly the problem we'll solve in this article------man-machineinterface based on embedded.Focused on the environment of the industry field intelligent equipment's embedded software component platform, this paper designs communication subsystem based on embedded system MMB2004 and man-machine interface.This paper systemically introduces the developing procedure for the whole system,including how to design hardware and software system, also introduces the realization of function communications, and programs software to test this subsystem function.The updated embedded system MMB2004 has been debugged and will be used in the new project. By the test ,it is proved that is feasible, reliable and universal. This is the profitable attempt to develop the software component in the embedded and man-machine interface high real time operation system. Which make users and systems communicate with each other readily.
