In order to keep up with the latest international technologies which have been achieved recently.
We have to search continuously for the technological methods in order to improve the present situation of the institutions in the Syrian Arab Republic.
This research aims to build a network of Programmable Logic
Controllers (PLCs) with Human Machine Interface (HMI) and
supervisory control and data acquisition (SCADA) system, as well as, studying the most suitable protocols to build the network beside identifying the causes of choosing the protocol.
After studying and identifying it, we had better to use the
automated industrial network to improve the present situation of water company concerning with getting meters data accurately as fast as possible.
We build the mentioned network by means of a group of PLCs, so that, each one could be used to get the data for an avenue in Hama city.
These distributed controllers would be connected by a central
router in order to pass all the data to the water company center. We will use a HMI and SCADA system for showing collected data, controlling, and saving the collected data.
This HMI and SCADA system will be connected to the same
PLCs, and thus, we will get a distributed industrial network.
The weigh feeders constitute an essential part of any production facility, where its
control and supervision system is one of the important things that should be characterized
by precision and reliability.
From this research we will try to develop
the unreliable control and supervision
system of the weigh feeders in mills of raw materials department in Tartous cement and
building materials company. The work Will focus on trying to avoid errors and problems
that the old control system suffered in order to reach the best possible performance of
weigh feeders, facilitate maintenance process and reveal the problems as they happen by
proposing controlled weigh feeders by programmable logical controllers from SIEMENS
corporation with processor (CPU 315-2 PN / DP), and design supervision and collection
data system using software (WINCC Flexible sp3 2008).
We'll apply the steps of the study practical on the weigh feeder of mill of raw
materials, and we will conduct the necessary tests to ensure the validity and accuracy of the
new control system, therefore the range of reliability.
This research aims to design
an effective system for detection of various known and unknown intrusion and
snooping operations which are SCADA systems exposed to, depending on the
idea of Markov Chains and the concept of probability windows.
