Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Consider in current relaying protection anti-misoperation and instruct owing to often lacking secondary operation ticket, cause pressing plate leakage throwing, miscarrying, vacation to throw; The effective definite value of relaying protection, not in situations such as definite value districts, causes relay protection operation accident, the invention provides relaying protection method for preventing misoperation.
A kind of relaying protection method for preventing misoperation, comprises, step 1, obtains the first information of relay protection device; Step 2, according to operation task determination secondary device; Step 3, generates secondary operation ticket according to the described first information to the relay protection device in secondary device; Step 4, sends described secondary operation ticket for performing.
Compared with prior art, the moment obtains the first information of relay protection device, and automatically generates secondary operation ticket according to operation task, makes up the blank without secondary operation ticket in operation maintenance personnel relay protection operation, decreases the probability of relaying protection misoperation.
Describe in detail below by an embodiment,
In relay protection device operation, occur misoperation, the invention provides a kind of fool proof method of relaying protection, the method comprises, as shown in Figure 1:
Step 101, obtains the first information of relay protection device;
Because needs formulate generation secondary operation ticket according to the first information of relay protection device and concrete operation task, accurately, in time the first information of acquisition relay protection device is most important.
The collector that wherein first information is connected due to relay protection device gathers, this information comprise following any one: pressing plate throws information of moving back, the definite value of relay protection device and definite value district, secondary device maintenance.
Step 102, according to operation task determination secondary device;
The secondary device that different operation tasks is corresponding different.Operation task is many-sided, such as: throw by scheduling requirement and move back pressing plate; Definite value district is switched by scheduling requirement; Secondary device is maked an inspection tour; Secondary device maintenance etc.
Step 103, the first information according to relay protection device generates secondary operation ticket to the relay protection device in secondary device;
Relaying protection anti-misoperation apparatus generates secondary operation ticket according to selection, then carries out examination & verification and confirms, once will be entered in step 103 by examination & verification.
Step 104, sends secondary operation ticket for performing.
The send mode of secondary operation ticket can be sent by signal.
Wherein, in other specific implementation process, in order to improve the accuracy of relaying protection, avoid operation maintenance personnel to go to the wrong way interval, relay protection operation is slipped up, and can also increase following steps between step 103 and step 104:
Step 105, sends to electron key by the relay protection device open command in secondary device.
Electron key opens screen door or the terminal chamber door of corresponding relay protection device according to open command.This open command can be bundled in operating equipment information and pass to electron key.
On the other hand, in other specific implementation process, in order to improve the accuracy of relaying protection, can also following steps be increased between step 103 and step 104:
Step 106, simulation make secondary operation ticket stubs capable after relaying protection result and store.
This relaying protection result is the simulated operation in relaying protection anti-misoperation apparatus, and the result of this simulated operation is comparatively accurate.
In order to improve the practicality of step 106, after step 104, increase following steps:
Step 107, the second information of relay protection device after reception secondary operation ticket stubs are capable;
After secondary operation ticket stubs are capable; the information of relay protection device can be changed; collect this write information in time and be shared in relaying protection anti-misoperation apparatus; compare with the simulated operation result wherein stored; by analyses and comparison result, both can determine that whether actual relay protection operation was correct.
Step 108, described second information and described relaying protection result are checked, if confirmation, then relaying protection completes; If check exception, send warning signal.
In this relaying protection method for preventing misoperation, ticket is operated to secondary working and implementation status carries out multistage auditing, stopped relay-protection pressing plate miscarrying accident, effectively controlled the generation of all kinds of accident of relay protection device.Adopt electron key to carry out unified management to relay protection device screen door lockset, stopped protective relaying maloperation accident, and stopped to be strayed into run that relay protection device causes touch accident by mistake.
