Our country natural gas resources richer, a
natural gas field minute cloth cover is broad, and often is far away
the area which the industry cities and the population resides
collectively; The gas well extremely disperses in the identical
natural gas field, because it locates the geographical position is
different, mining position respectively different, its natural gas
ingredient and contains the impurity not one. Generally
speaking, except loses in the craft in the collection to need a set
the automatic control instrumental equipment which adapts with the
process unit to come to separate, the measurement, the heat transfer,
the accent presses and so on the process carries on outside the
examination and the control, but also needs to have with looks over
the complete dispatch management system management system which
produces adapts. Our country oil field natural gas mainly
belongs to the oil gas, its distribution situation picks the oil
refinery according to the oil field the position to set up one by one,
oil field original vast, picks the oil refinery geographical position
dispersible, mutually is away from extremely far, therefore the
natural gas company subordinate's various gas conditioning stands
similarly extremely disperses, therefore establishes a security
reliably, stable, the unification, the modern production management
network system is extremely important.
East the earth telecommunication company (KYLAND) designs, the
development, the industry level optical fiber redundant network
system, from the enhancement control network security, the stability,
the reliability focuses, begins from the product production design, to
establish a set to suit the petroleum chemical industry automatic
control system the industry redundant network system. Guarantees
the network system to be able to manage for the enhancement
organization, the production management level, makes the contribution.
According to the natural gas company's regional distribution,
the entire control system network divides into three structures.
1. management levels use KIEN 9000 to compose the 1000M industry level optical fiber
redundant ring net, on meets INTERNET.
2. controls levels use KIEN 6000 to
compose the 100M industry level optical fiber redundant ring net, with
on position machine connected constitution control network.
3. similarly the control network which 2,000 is composed by KIEN, gathers several dozens
kilometers outside the data security, the effective transmission
control room.
Through the use east earth telecommunication company's network
management software, carries on the entire network the effective plan.
Causes the entire network to be safer.
