> Outlines:
In SCADA application and so on in oil field oil well, pipeline,
fuel gas, hot net monitoring, because monitors the scene geography
dispersible, the correspondence network constructs relatively complex,
therefore the GPRS/CDMA migration network becomes in the SCADA
application one mainstream application network way, but this kind of
SCADA system equipment type many, because between software and
hardware communication agreement unification standard, and the very
many domestic and foreign HMI/SCADA monitoring software product not
directly supports through the GPRS/CDMA migration network
communication and the long-distance equipment communication, therefore
between software and the equipment has seriously affected through the
long-distance motion communication transparent transmission question
the automated system performance, the debugging time limit for a
project, the cost and the system is stable.
At present the OPC standard passes through many years
application, is already accepted by each big software and hardware
merchant, becomes the fact software to interlock the standard,
therefore the OPC product which so long as is connected supports the
GPRS application then to be allowed to solve this bottle of diameters
problem.
The three dimensional strength controls promotes the OPC-GPRS
solution, the strength controls MOPC product OPC Server not only to
support RS232/485, the digit dialing, the broadcasting station,
TCP/IP, UDP/IP and so on ordinary physical way data mode gathering,
moreover supports through outside the long-distance GPRS/CDMA
communication and the great distance SCADA monitoring equipment
carries on the communication, such domestic and foreign any supports
the OPC product to control MOPC through the strength to be allowed to
carry on the communication with any long-distance equipment to
complete the scene the monitoring.
Typical characteristic:
The strength controls MOPC to use the independent buffer
management and the data processing process to each GPRS DTU gathering
equipment, cannot because DTU increase affects the overall system the
gathering speed, also cannot because the partial DTU breakdown affect
other DTU correspondence.
The strength controls the OPC product to be allowed foreign to
provide the expansion programming connection, third party software may
the pMOPC product which controls based on the COM way visit strength
gain the monitoring data.
The support many equipment will map OPC Server, may the OPC
connection which will unify the different agreement many equipment
factory communication to outside provide the communication way, then
by will fit out the many kinds of equipment communication unification
package OPCSERVER to provide to other procedures the data, for
instance domestic and foreign SCADA system software like IFIX,
INTOUCH, CITECT and so on.
