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.
