Embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Embodiment
As shown in Figure 1, the hot standby control system of a kind of shield machine, this system comprise hot standby PLC main frame 1, hot standby PLC guest machine 2, two hot standby Ethernet switches 3, switch 4 and under hang standby.Hot standby PLC main frame 1 is connected with a hot standby Ethernet switch 3.Hot standby PLC guest machine 2 is connected with another hot standby Ethernet switch 3.Hot standby PLC main frame 1 adopts the CPU synchronization link to be connected with hot standby PLC guest machine 2, and the CPU synchronization link is mainly used in the transmitting synchronous of the database data of PLC.Adopt synchronization link to connect between two hot standby Ethernet switches 3, the ETY synchronization link of hot standby Ethernet switch is mainly the transmitting synchronous for hot standby diagnostic message.Switch 4 and two hot standby Ethernet switches 3 connect into the Ethernet looped network, the utilization of Ethernet looped network is mainly the redundancy that has strengthened network itself, when occurring 1 place's fault in network when (comprising netting twine physical hazard or exchange fault), system works is unaffected.Under hang and standby with switch 4, be connected.System of the present invention adopts two groups of hot standby PLC controllers and hot standby Ethernet switch, and one group is main process equipment, and one group is stand-by equipment.Control method is as follows, when control system is normally moved, and hot standby PLC main frame normal operation, hot standby PLC guest machine is in holding state, only with hot standby PLC main frame, carries out data and synchronizes; When hot standby PLC hostdown, hot standby PLC guest machine replaces main process equipment operation work within a certain period of time fully.When system is normally moved, the main process equipment normal operation, stand-by equipment is in holding state, only with main process equipment, carries out data and synchronizes.When the main process equipment fault, stand-by equipment can replace main process equipment operation work fully at the switching that is no more than 500ms in the time, has guaranteed the integrality of shield structure control system uninterrupted and current data of executive program flow process when hostdown.And utilize two groups of hot standby Ethernet switches to form an Ethernet looped network, and formed the higher Ethernet topological network of redundancy performance, when having arbitrary place stube cable to damage in the Ethernet looped network, do not affect the device talk work of all websites on whole network.
In order to realize the ETY synchronization link, hot standby ethernet module ETY is very crucial parts, is arranged on respectively in the same groove position of two PLC frames, and the firmware version of ETY also must be consistent.Connection between ETY is called ETY and synchronously connects, and is the passage for other information (comprising diagnostic message) of transmission and reception and hot standby System Dependent.ETY occurs in pairs, is bearing the necessary two kinds of functions of hot standby system redundancy in system.At first, can convey a message, these information are used for judging whether that the wrong or power supply supply discontinuity whole mainframe due to application program causes not response of main PLC, and help PLC to causing the condition of switching to be distinguished.Secondly, ETY becomes by the basis of Ethernet TCP/IP network with redundant fashion control I/O.In ETY module on mainframe, operation I/O scan service could be set up Redundant Ethernet I/O.
In this looped network, under hang standby as follows: foaming system 5; Filling system 6; Guidance system 7; HIM computer 8(or claim man-machine interaction HIM touch-screen), be responsible for real-time parameter to shield machine and show and the assigning of some action commands; Ground monitoring system 9; In distributed I/O website 12(website, distributed I/O module is set), be responsible for as the collection of the input signals such as pressure sensor, flow sensor, switching signal and as the output of the output signal of the control executive components such as relay, electromagnetically operated valve; Operation button switch, be responsible for assigning of the important instruction of shield machine; Wireless I/O transmission equipment 10, be responsible for the signal of Digiplex is received and be transferred to the PLC controller; Other electromechanical equipments, for example the cutterhead frequency converter 11, are responsible for receiving the control command in network and carry out, and the real-time parameter of frequency converter is transferred to the PLC controller.
Set up by hot standby design and Ethernet looped network that control system core PLC is controlled, guaranteed the integrality of shield structure control system uninterrupted and current data of executive program flow process when hostdown, improved the fault-tolerant ability of ethernet communication network on hardware and software, the redundant reliability energy of the shield machine control system that improves greatly.
The foregoing is only preferred embodiment of the present invention,, not in order to limit the present invention, should be pointed out that all any modifications of doing within the spirit and principles in the present invention, be equal to replacement and improvement etc., within all should being included in protection scope of the present invention.
