The invention provides a drilling control and data
collection system of a self-elevating platform. The drilling control and data
collection system of the self-elevating platform is a control and data
collection system based on a redundant
programmable logic controller (PLC) and is characterized in that a main
hull equipment drilling PLC, a mud pit PLC, a
mud pump operating platform PLC, a drilling meter PLC and a
drill floor
control equipment PLC are respectively arranged in each area and are respectively conducted with a 412 H processor of a PLC main
station. An iron
roughneck PLC, a
top drive PLC and a hydraulic
power unit PLC are conducted with the 412 H processor, and a
motor variable frequency controller is conducted with the 412 H processor through a CU 320
control unit. The 412 H processor is connected into a driller room switchboard through an
Ethernet network through connection
optical fiber, and a driller control industrial computer is conducted with the driller room switchboard through an
Ethernet network. A generator controls the PLC to be directly conducted with the driller control industrial computer through the
Ethernet network. The drilling control and data collection
system of the self-elevating platform has the advantages of being high in integration level, good in reliability, strong in
operability and the like, and meanwhile, driller control
layout is reasonable and is controlled to display with equipment in a centralized mode, and operating is convenient.
