Abstract
The utility model provides a security control system for pure LNG power boats and ships, including the same functionality and mutually independent first control subsystem and second control subsystem, wherein first control subsystem and second control subsystem all include controller and the display screen, sensor group and the valve unit that connect rather than the electricity. Each other is for the control between two sets of subsystems, and real time monitoring is running state each other, can not be found in real time after avoiding one set of system to break down, one set of subsystem back of breaking down in addition, thus another set subsystem can go beyond one's commission output control signal through the signal distribution module that sets up between two sets of subsystems and control actuating mechanism such as corresponding valve, avoid one set of system failure after this system correspond parts state out of control.
Description
Technical field
The utility model relates to ship control field, particularly relates to a kind of security control system for pure LNG powered ship.
Background technology
Along with the requirement of the overall situation such as national energy structural adjustment and energy-conserving and environment-protective, LNG powered ship obtains extensively promoting and development, in the use of LNG as boats and ships sole power fuel, seems particularly important to its security control.
In general code requirement and actual use, pure LNG powered ship uses two to overlap independently security control system be intended to meet the prerequisite of system redundancy in safety and protection monitoring under, or a set of equipment two independently control system, uses in hardware configuration and function and overlaps the not too large difference of independent security system with two.Two control system are completely independent, and can not communicate each other, when one of them control system breaks down, another one can not carry out emergency treatment to fault automatically in time.And due to two systems completely independent, just result in and not only in hardware configuration, there is the wasting of resources, in actual uses of user, cause use complexity, safeguard loaded down with trivial details, two cover system fitnesss are not high yet.
Utility model content
The technical problems to be solved in the utility model is, under the prerequisite meeting code requirement, provides between a kind of multisystem and can mutually monitor, and break down the security control system for pure LNG powered ship that can automatically process in time.
For achieving the above object, the utility model adopts following technical scheme: a kind of security control system for pure LNG powered ship, comprise the first identical and separate control subsystem of function and the second control subsystem, wherein the first control subsystem comprises the first controller and the first display screen be connected electrically, the first subsystem sensor group and the first subsystem controls valve group, and the second control subsystem comprises second controller and the second display screen be connected electrically, the second subsystem sensor group and the second subsystem controls valve group; First controller of the first control subsystem and the second controller of described second control subsystem adopt CAN communication pattern to be connected; The signal distribution module be electrically connected with the first controller and second controller respectively is also provided with between two control subsystem.
As preferably, security control system is also provided with the common sensor group and public operation valve group that are electrically connected with signal distribution module respectively, both can avoid the repeated configuration of sensor, triangular web also can be avoided to extract signal, and after the system failure, signal cannot by another systems axiol-ogy.
As preferably, security control system is also provided with remote control module, tele-control system adopts CAN communication pattern to be electrically connected with the first controller and second controller respectively, remote control module can overlap the real-time status of control subsystem by tracking display two simultaneously, and realizes the parameter adjustment of two cover control subsystem.
The beneficial effects of the utility model are:
1, two cover control subsystem are connected by CAN communication mode, monitor each other, monitor running status each other in real time, can not be found in real time after avoiding set of system to break down.
2, after set of subsystem breaks down, another set of subsystem can be gone beyond one's commission by the signal distribution module designed between two systems and exported control signal thus control the topworks such as respective valves, avoids this system corresponding component runaway condition after set of system fault.

Shown in figure: 1, the first control subsystem; 2, the second control subsystem; 3, signal distribution module; 4, remote control module; 5, common sensor group; 6, public operation valve; 11, the first controller; 12, the first display screen; 13, the first system sensor group; 14, second system operation valve group; 21, second controller; 22, second display screen; 23, second system sensor group; 24, second system operation valve group.
Embodiment
Below in conjunction with exemplary embodiment, embodiment of the present utility model is described:
The utility model provides a kind of security control system for pure LNG powered ship, comprise the first control subsystem 1 and the second control subsystem 2 that function is identical and separate, wherein the first control subsystem 1 the first display screen 12 of comprising the first controller 11 and being connected electrically, first subsystem sensor group 13 and the first subsystem controls valve group 14, the second display screen 22 that second control subsystem 2 comprises second controller 21 and is connected electrically, second subsystem sensor group 23 and the second subsystem controls valve group 24, first controller 11 of the first control subsystem 1 adopts CAN communication pattern to be connected with the second controller 21 of the second control subsystem 2, two control subsystem are monitored each other, real-time monitoring running status each other, can not be found in real time after avoiding set of system to break down, the signal distribution module 3 be electrically connected with the first controller 11 and second controller 21 respectively is also provided with between two control subsystem, and the common sensor group 5 be electrically connected with signal distribution module 3 respectively and public operation valve group 6.For common signal as signals such as tank temperature pressure, jointly used by signal distributor.Both can avoid the repeated configuration of sensor, triangular web also can be avoided to extract signal, and after the system failure, signal cannot by another systems axiol-ogy.
Security control system is also provided with remote control module 4, remote control module 4 adopts CAN communication pattern to be electrically connected with the first controller 11 and second controller 21 respectively, remote control module can overlap the real-time status of control subsystem by tracking display two simultaneously, and realizes the parameter adjustment of two cover control subsystem.
The part do not set forth in instructions is prior art or common practise.The present embodiment only for illustration of this utility model, and is not used in restriction scope of the present utility model, and the amendment such as the equivalent replacement that those skilled in the art make for the utility model is all thought to fall in this utility model right claim institute protection domain.
