Specific embodiment
Multiple console electric-control system is most commonly that two, three host computers of setting, the automatically controlled system of multiple console larger at present
System has five, six host computers.Multiple console because of multiple console electric-control systems more than three host computers and three host computers
Electric control system controls principle is identical, therefore hereafter will be (to correspond to host computer pc1～pc3, and jerk is pressed with three control stations
Button e1～e3), as a example the multiple console electric-control system of three major loop subsystems (major loop subsystem m1～m3), to the present invention
The jerk protection control method of multiple console electric-control system is described in further detail.
Embodiment one:
In the present embodiment, specifically host computer pc1～pc3 carries out man-to-man control to major loop subsystem m1～m3, but its
Control planning is compared with prior art and on-fixed.
As shown in Fig. 2 the jerk of the present embodiment multiple console electric-control system protects the step of control method to include:
1) in multiple console electric-control system the host computer of each control station be connected with main control module by network, main control module
On the basis of control output end is connected with the breaker control end of each major loop subsystem respectively, by the jerk of each control station
The physical connection of button is connected with the input of main control module respectively；
2) main control module distributes a major loop subsystem when the host computer of each control station logs in for each host computer, and
The input signal of the physical connection of the scram button of each control station is passed through the major loop subsystem of Automatic Program associated allocation；
3) when the scram button of any one control station is pressed, main control module is by the major loop subsystem associated by input signal
Chopper disconnect realize jerk protection.
The main control module of the present embodiment is plc main control module, can also adopt other control chips in addition as needed.As
Shown in Fig. 3, the physical connection of the scram button of each control station is connected by the present embodiment respectively with the input of main control module, will
To three input ports of plc main control module, three output points of plc main control module replace the physical connection reconfiguration of former scram button
Circuit for former jerk trip(ping) circuit.When pressing scram button, emergent stop signal is first input into plc main control module, then through plc master
The jerk control program of control module instructs in combination with host computer, controls output corresponding major loop tripping operation.
In the present embodiment, described step 2) detailed step include:
2.1) it is directed to each multiple flag of host computer Initialize installation in advance and resets, and each host computer is corresponding many
The quantity of individual flag is identical with the quantity of the major loop subsystem in multiple console electric-control system；As shown in figure 4, the present embodiment
The flag of middle corresponding host computer pc1 includes flag 11, flag 12 and flag 13, and flag 11 is 1p1, flag 12
For 1p2, identifying 13 is 1p3；The flag of corresponding host computer pc2 includes flag 21, flag 22 and flag 23, flag
21 is 2p1, and flag 22 is 2p2, and mark 23 is 2p3；The flag of corresponding host computer pc3 includes flag 31, flag 32
With flag 33, flag 31 is 3p1, and flag 32 is 3p2, and flag 33 is 3p2, and above-mentioned flag is defaulted as 0, every time on
Electricity initialization once, that is, resets；
2.2) when the host computer of each control station logs in, all unappropriated major loop subsystems are generated list and supplies user to select
Select, and all major loop subsystems that receive user selects, all major loop subsystems that user is selected are distributed to and logged in
Host computer, the major loop subsystem that user is selected, the corresponding home position of both host computers 1 logging in, and other are upper
The corresponding flag of machine forces to set to 0；
2.3) by the major loop subsystem of the input signal associated allocation of the physical connection of the scram button of each control station.
Host computer logs in and specifically refers to log in host computer user program, logs in and selects during host computer user program to prepare to control
Major loop subsystem, enter the major loop subsystem of selection after confirmation, now host computer is by the major loop in plc main control module
The corresponding home position of subsystem 1, other set to 0.Referring to Fig. 5, (1) host computer pc1 logs in, in major loop subsystem selection interface
There is provided major loop subsystem m1～m3 available (one-out-three), user have finally chosen major loop subsystem m2, host computer pc1
In the flag 11～flag 13 of corresponding major loop subsystem m1～m3, flag 12 is set to 1, flag 11, flag 13
Set to 0, host computer pc1 is also by loop choice real-time data sharing on all in the LANs such as host computer pc2, host computer pc3
Position machine；(2) host computer pc2 logs in, due to passing through loop choice real-time data sharing between host computer pc1～host computer pc3, main
Subsystem m2 is unavailable in loop, and host computer pc2 only has major loop subsystem m1, m3 can in major loop subsystem selection interface
Selective (alternative), user have finally chosen major loop subsystem m3, the corresponding major loop subsystem m1～m3's of host computer pc2
In flag 21～flag 23, flag 23 is set to 1, and flag 21, flag 22 are set to 0, and loop is also selected by host computer pc2
Select real-time data sharing to all host computers in the LANs such as host computer pc1, host computer pc3；(3) host computer pc3 logs in, due to
Pass through loop choice real-time data sharing, subsystem m2, m3 are unavailable for major loop between host computer pc1～host computer pc3,
Host computer pc3 only has major loop subsystem m1 in major loop subsystem selection interface, and available (single choice, user have finally chosen
In the flag 31～flag 33 of the corresponding major loop subsystem m1～m3 of major loop subsystem m1, host computer pc3, flag 31
Be set to 1, flag 32, flag 33 are set to 0, host computer pc3 also by loop choice real-time data sharing to host computer pc1, on
All host computers in the LANs such as position machine pc2.No matter which platform host computer exits, it is automatically releasable authority when exiting that is to say, that leading
The corresponding flag of corresponding major loop subsystem in plc main control module can be reset by the right to choose release of loop subsystem.
The major loop subsystem that host computer have selected, the mastery routine of plc main control module just can call corresponding subprogram mould
Block, otherwise program never call, so can improve the plc executing efficiency of plc main control module moreover it is possible to realize the journey of major loop
Sequence interlocks, and improves the safety of whole electric-control system.The flag of the corresponding same major loop of different host computers is being called
During major loop program module, not only interlock between each flag, and, once two other flag of home position 1 is strong
System sets to 0.So can ensure that a major loop only can call once.The unique master that in the present embodiment, receive user selects returns
During subsystems, the major loop subsystem that user is selected distributes to the host computer logging in, the major loop subsystem that user is selected
System, the corresponding home position of both host computers 1 that logs in, and the major loop subsystem that user is selected is corresponding with other host computers
Flag force set to 0.
