Automatic control system for gas-distribution station
ACS GDS is intended for the control and automation of one- or two-thread gas-distribution stations of different
capacities.
MAIN TASKS TO BE SOLVED
Execution of automatic control programs in emergency situations.
Tap control
Ability to query gas flow rate calculators via interface, calculation of summary gas flow rate and control of gas odor system.
Data acquisition, processing and archiving.
Automatic transmission of emergency and warning signals to the workstation operator and the recording of each emergency event.
Change of warning and emergency setups from the built-in and remote operator workstation.
Control of exhaust ventilation, emergency light and acoustic signaling.
Good condition monitoring of all operating mechanisms of technological equipment, continuously runs self-diagnostics on all system modules and supply units.
Displays information about process flows and the state of equipment graphically via the remote operator workstation.
Integration with the protection signaling system.
Integration with the fire signaling system.
Interaction with remote control & monitoring system supporting the command transmission via communication
line from the operator to control objects, and remote control devices in operator house.
Data transmission to information-control systems via interface lines, telephone lines or radio channel.
Provides uninterrupted electricity supply support of ACS GPA and automation devices in the event of voltage
loss from an uninterrupted supply assembly with the use of a back up battery (from 2 to 8 hours).
