The principle of the present invention is described as follows:
Anchoring positioning control system is as the important component part of anchoring system device, the configuration of its control system device and property
Can directly determine the safety and reliability of anchoring system, existing anchoring positioning control system generally uses high-performance
PLC, it is achieved centralized Control, but this kind of control system Financial cost is high, and meanwhile, once this Control System NetWork interrupts, then part
Winch cannot be carried out operation, and safety and redundancy are relatively low, can have a strong impact on the use of a whole set of four-point mooring alignment system.For
This kind of present situation, the design provides a kind of jack-up unit four-point mooring positioning control system and control method thereof, structurally, bag
Include man-machine interaction assembly, control unit assembly, power drive assem and performance element assembly；Man-machine interaction assembly, for operation
Information transmission between person and performance element assembly provides the assembly supported；Control unit assembly, realizes controlling for control system
Function provides the assembly of hardware support, is mainly made up of bridge controller, stem controller and ship stern controller, and bridge controls
Device, stem controller and ship stern controller all configure the PLC of low side, carry out communication by EPA between each controller,
Realize decentralised control, see Fig. 2, the PLC of each controller configuration and all include that switch, CPU(are for turning the control instruction of reception
Turn to control signal), digital signal input/output module (DI DO), analogue signal input/output module (AI AO), respectively control
The switch of device processed all carries out communication by the CPU of EPA Yu each controller, and the switch of bridge controller passes through work
Industrial Ethernet and touch screen, the switch of stem controller, the switch of ship stern controller carry out communication；Power drive assem,
Power management and the assembly of power distribution is provided, mainly by main pump motor starter and control pump motor starter group for equipment
Becoming, during work, power drive assem starts or stops main pump group and controls pump group according to the control signal received；Execution unit set
Part includes four pumping plants and four positioning winch, and two of which pumping plant and two positioning winch are positioned at the two ends of stem, other two
Individual pumping plant and two positioning winch are positioned at the two ends of ship stern.
In above-mentioned control system, between touch screen, bridge controller, stem controller, ship stern controller, there is communication number
According to exchange, accordingly, it would be desirable to analyze the running status of system under communication failure condition, to reduce the equipment operation damage under extreme case
Evil and the danger produced, improve the stability of equipment control performance the most to greatest extent；First, by analyzing touch screen and ship
The ruuning situation of system when bow controller or ship stern controller generation communication failure, finds the control of system and runs not by this event
The impact of barrier, this is because, in native system, touch screen is only used as the Surveillance center of system running state, and touch screen is not involved in control
System, the control parameter arranged by touch screen is all write the power down of PLC and keeps Zone R (to control parameter and be saved in this district so that be
When system occurs communication failure, controlling parameter can be saved), when there is communication failure, only lose system running state
Overall monitor, be not result in the danger of system exception；Secondly, by analyzing bridge controller and stem controller or ship stern control
The ruuning situation of system during device generation communication failure processed, owing to the control function of native system is by stem controller and ship stern control
Device processed realizes, and bridge controller is only only completed transmission and the winch fortune relevant with pumping plant of driver's cabin control panel control signal
The display of row state, therefore, when driver's cabin control panel does not possesses operating right, bridge controller is logical with bow stern controller
Letter interrupts, and does not interferes with the use of system, even bridge controller does not powers on, it is also possible to the control authority of winch switched to
On-site control case carries out the operation of winch；When driver's cabin control panel has operating right and cab panel does not carries out any behaviour
When making, bridge controller and the communication disruption of bow stern controller, then the winch state before and after interrupting keeps consistent, will not be to equipment
Produce uncontrollable influence factor, now, control authority is switched to on-site control case and also winch can be carried out normal operating；When
When driver's cabin control panel possesses operating right and operates, bridge controller interrupts suddenly with the communication of bow stern controller,
Then the winch after communication disruption maintains the mode of operation before interrupting, and now, the scram button of cab panel need to be used to make equipment
Emergency shutdown, jerk needs to switch to winch control authority on-site control case after resetting, and restart motor could be by machine
Carry out normal operating.
