Description
Technical field
The present invention relates to switch cabinet multi-state changing method.
Background technology
Switching between the multimode of switch cubicle experienced by the transformation being manually switched to automatic switchover, although existing transformation substituted for the object (becoming machine by hand) performing and switch, could not operation order be departed from, must perform step by step according to operation order, switch slowly, intelligent low.To interlock switch cubicle group, especially large complicated switch group improves its switch speed, can save a large amount of power-on times, restore electricity as early as possible, is significant to reduction power-off loss.
In view of this, the invention provides a kind of switch cabinet multi-state changing method, switch by intelligence and replace operation order, accelerate switch speed.
Summary of the invention
The object of the present invention is to provide a kind of switch cabinet multi-state changing method, switch by intelligence and replace operation order, realize multistep simultaneously and switch, accelerate switch speed, save power-on time.
In order to reach above-mentioned purpose, technical scheme of the present invention is as follows.
Switch cabinet multi-state changing method, comprises the following steps:
(1) allocation unit conditional code, for each can the state assignment unit conditional code that has of executive module, represent component states by unit conditional code, the switching Ji Shi unit conditional code of component states switches;
(2) setting switches the necessary switching condition of unit conditional code;
(3) assembled state code sequence, according to the assembly corresponding to each state of switch cubicle, the unit conditional code of corresponding assembly is combined as the conditional code sequence of switch cubicle, represents switch cabinet state by conditional code sequence, namely the switching of switch cabinet state is that conditional code sequence switches;
(4) compare conditional code sequence, the similarities and differences of comparison object conditional code sequence and current state code sequence, the unit conditional code of concrete only more same assembly, the intersection of carrying out between different assembly does not compare;
(5) judge switching condition, in conjunction with current state code sequence, the comparative result according to step (4) judges needing to perform its unit conditional code of assembly switched switches whether meet necessary switching condition;
(6) perform switching, perform the unit conditional code meeting necessary switching condition in step (5) and switch;
(7) poll switches, and repeats step (4) to (6) to the switching of completion status code sequence.
In another embodiment, assembly comprise circuit breaker, handcart, cutter, the state correspondence had comprises separating brake, combined floodgate, working position, test position, co-bit, point position.
In another embodiment, necessary switching condition is mutual exclusive conditions dictate between each component states.
The inventive method, multiple states of switch cubicle are represented in the mode of conditional code sequence, computing can be compared between each conditional code sequence, and with necessary switching condition as performing the criterion before switching, the similarities and differences of current state and dbjective state are compared in execution again after switching, the criterion before again switching as execution with necessary switching condition is also until all switchings complete reach target switching.
The inventive method is in the process performing handover operation, as long as meet necessary switching condition namely perform handover operation, without the need to performing step by step according to operation order, multiple handover operation can be performed at one time, remarkable acceleration switch speed, save a large amount of power-on times, restore electricity as early as possible, reduction power-off loss is significant.
In order to further illustrate the present invention, the present invention will be further described by way of example below.

Switch cubicle has cold standby state, namely circuit breaker 0, handcart 0, cutter 0 time switch cubicle be in this state, its conditional code sequence is 000.
According to table 3,4 kinds of states that the present embodiment switch cubicle has, forward another state to from a certain state and have the arrangement of 4 × 3=12 kind, i.e. 12 kinds of switchings, according to existing way be with artificial mode by these 12 kinds switch corresponding to detailed step make operation order, perform when switching and perform by operation order step by step, not intelligent, switch speed is slow.
According to the present invention's spirit, the present invention, but to be performed to step (7) automatic decision by step (4) without operation order when carrying out switch cabinet state and switching.
Illustrate the course of work of step of the present invention (4) to step (7) below.
switch cubicle switches example 1
Spirit of the present invention for displaying is how to realize switch cubicle to be switched to inspecting state by running status by this example.
According to table 3, the conditional code sequence of switch cubicle running status is 110, and the conditional code sequence of switch cubicle inspecting state is 001, namely current state code sequence is 110, and dbjective state code sequence is 001, according to comparison principle of the present invention, the only unit conditional code of more same assembly, comparative result is:
