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 the same time,industrial control based on munication appears and shows tremendous advantages.
munications provides faster connection and data transfer also
has advantages such as charge in information and IP— burst out data transfer and sporadic vast data transfer are supported,which highly adapts to the characteristics and requirements.
After profound research parison between munications 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 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 work cells and interfaces in detail;at last makes great efforts to conclude the interface protocols between the GPRS and external parses the relation of connection between the GPRS and works,makes clear the munication mechanism of GPRS.
Then,a new design of concrete mix control based on GPRS technology is brought the same time,through parison between several wireless data transfer modes,we affirm the advantages of GPRS in remote the basis of it,discusses several means we structure more importance will be attached to the ones the data center server accesses the 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 s
