Abstract


With the maturation and development of Information Technology in the domain of industrial automatism,traditional industrial control emerges several regrets such as low efficiency and resource wasting.At the same time,industrial control based on wireless communication appears and shows tremendous advantages.GPRS communications provides faster connection and data transfer rates.It also has advantages such as charge in information and IP-supporting.Intermittent burst out data transfer and sporadic vast data transfer are supported,which highly adapts to the characteristics and requirements.After profound research and comparison between GPRS communications and traditional industrial control ,we did close connection GPRS technology and especial requirements of transformer control in concrete mix system and brought forward a type of design in industrial control,which uses GPRS technology.After that,we began to research and develop the system of“Remote monitoring system Based on GPRS”.The paper first presents the features of GPRS;then analyzes the functions and relationship of GPRS network cells and interfaces in detail;at last makes great efforts to conclude the interface protocols between the GPRS and external data networks.It parses the relation of connection between the GPRS and Internet networks,makes clear the data communication mechanism of GPRS.Then, a new design of concrete mix control based on GPRS technology is brought forward.At the same time,through the comparison between several wireless data transfer modes,we affirm the advantages of GPRS in remote control.on the basis of it,discusses several means we structure the networks.Here more importance will be attached to the ones the data center server accesses the Internet.Since the technologies of dynamic domain name and port mapping are important and usually used. Since it ,It demonstates the hardware design of data acquisition system including the minimum system design based on the SumSung ARM-core microcontroller S3C44B0X,and the uClinux development environment.The design of GPRS telecommunications is the most important part.The part tells us the way to build connection between GPRS modules and control center and the way to achive data reception and sending in long distance.The part demonstrates how to design the MC35i dial-up program.Analyzes the principle of the point-to-point protocol.Then, demonstrates the buffer pool and self-defined communication protocol to assure data transfer securitly.At last,dissects the design of the monitor center software.
