| With the information age coming information technology has become a keyword technology that can impulse science and technology and country economy to develop. Appearance is a basic tool that measure and control the information of substance word, and also is the headstream and composement of information industry. The develop level of modern appearance is the importment embodiment of science and technology level and compositive national power. The produce level of appearance reflects the civilization degree. The automatization appearance and control equipment as a industry automatization technology is rdaching at a genuine numeral intelligentize and network age with the driving of high and new technology. Almost years, essence and work elements of automatization appearance are changing with the development of many high and new technology, especially the development of micro-electronics micro-machines new material and new technics, and the extensive application of computer and communicate technology. This realized better function that traditional appearance count not do.And brainpower appearance is coming into being.Brainpower instrument is the outcoming of measure instrument conjointed computer technology, and is a measure instrument that has microcomputer or microprocessor.It has intelligent function because it has the function that can memory ,operate ,logic judge and automatization operate data.This paper adopts the TMS320F2812DSP chip,it is produced by the TI Co.The whole design bases on MMB2004 field bus control system.This task completed the hardware design of hypogyny computer brainpower modules and make the appearances based SCM into the appearances based on DSP.Firstly, this paper introduces the development general situation of industry appearance and introduce the DSP chip TMS320F2812. Secondly, introduces the hardware design of appearance in details, include the main and I/O. This two parts include power circuit,EEPROM circuit,communication circuit,analogue port... |
