Detailed description of the invention
Refer to shown in Fig. 1, the present embodiment provides a kind of substation equipment maintenance and repair operation location and safe early warning method, and its step is such as
Under: step S1: all arrange radio-frequency (RF) tag on the different charging equipments of transformer station；Step S2: upkeep operation personnel are by with oneself
The evaluator carried reads information and the data of described radio-frequency (RF) tag；Step S3: analyze also during according to described information sum factually
Judge that described upkeep operation personnel, in the position of described transformer station, if its position is not in the range of safety zone, then send pre-
Alarming information.
Above-mentioned is core technology field of the present invention, substation equipment maintenance and repair operation location of the present invention and safe early warning side
Method, in described step S1, all arranges radio-frequency (RF) tag on the different charging equipments of transformer station, by described radio-frequency (RF) tag record institute
State various information and the data of different charging equipments in transformer station；In described step S2, upkeep operation personnel are by carrying with
Evaluator read the information of described radio-frequency (RF) tag and data, upkeep operation personnel can be real-time by the evaluator carried with
Read information and the data of described radio-frequency (RF) tag, wherein be may determine that it is which kind of equipment by described information, by described data
Described evaluator and the distance of described radio-frequency (RF) tag can be calculated, thus facilitate deciding on and whether enter deathtrap；Described step
In rapid S3, analyze during according to described information sum factually and judge described upkeep operation personnel in the position of described transformer station, if
Its position not in the range of safety zone, then sends early warning information, and prompting enters deathtrap, it is to avoid mistakenly entering charged chamber and
Step on charging equipment by mistake, so that it is guaranteed that the safety of upkeep operation personnel, improve the safety of operation；If its position is in place of safety
Territory, then upkeep operation personnel can arbitrarily walk about.
In described step S1, the different charging equipments of described transformer station include the equipment of upkeep operation, safe fence, ground connection
Equipment, wall bushing, pipe mother's wire and flat ripple reactance.In order to make upkeep operation personnel no matter from which direction near equipment time
All relevant information and data can be detected by described evaluator, described radio-frequency (RF) tag covers in described power transformation with 360 degree for principle
On the different charging equipments stood, and in described radio-frequency (RF) tag, record has the tag number on the kind of equipment and equipment of the same race, from
And be conducive to the equipment different by the information identification in described radio-frequency (RF) tag and confirm between equipment and described evaluator
Distance.
In described step S3, permissible according to information and the data of the associated radio frequency label of evaluator reading in described step S2
Analyze in real time and judge described upkeep operation personnel in the position of described transformer station, wherein by calculate described evaluator with described
Distance between radio-frequency (RF) tag, it may determine that described upkeep operation personnel are in the position of described transformer station, goes out with the valve Room 10 below
As a example by around line and upkeep operation personnel to illustrate the difference in described transformer station during earth potential upkeep operation charged
The distance between described evaluator and described radio-frequency (RF) tag how is calculated on equipment:
As in figure 2 it is shown, arrange wall bushing label 12 on described wall bushing 11, described first pipe mother's wire 13 is arranged
Pipe mother's wire label 14, and cloth horizontalization ripple reactance label 16 in described flat ripple reactance 15, when upkeep operation personnel close on,
Described evaluator read label information and calculate between described wall bushing 11, pipe mother's wire 14, flat ripple reactance 15 away from
From and position.Specifically, it is judged that range information between described evaluator and described radio-frequency (RF) tag uses mixed positioning algorithm, its
Based on range finding and two kinds of methods of angle measurement, described radio-frequency (RF) tag is positioned, if described evaluator and described radio-frequency (RF) tag away from
It is θ from line and the horizontal line angle for R, described evaluator and described radio-frequency (RF) tag, calculates described according to distance R and angle theta
The coordinate relation of earth potential working personnel and described charging equipment, wherein with the position of described evaluator as initial point, vertical direction
For vertical coordinate, geometrical relationship can obtain: tan (θ)=(x0-x1)/(y0-y1), and (x0-x1)2+ (y0-y1) 2=R2, by solution side
Journey group can be obtained by the particular location coordinate (x of label0-x1), calculate described service work personnel and described set through walls according to this
Pipe 11, described first pipe mother's wire 13 and the direct coordinate relation of described flat ripple reactance 15.If described earth potential working personnel
With described charging equipment close to safe distance, then send early warning information, thus avoid mistakenly entering charged chamber, it is ensured that upkeep operation people
The safety of member, improves the safety of operation.Wherein said safe distance is to be defined as reference with industry, such as described charging equipment
During for 10kV, described service work personnel are 0.4m with the safe distance of described charging equipment, with described charging equipment label are
The center of circle, justifies with 0.4m for radius, closes on deathtrap threshold value using the region in the range of circle as judgement, if service work personnel
Send early warning information during with described charging equipment close to 0.4m, so that it is guaranteed that the safety of upkeep operation personnel, improve operation
Safety.
Be discussed in detail the most again upkeep operation personnel how to calculate during isoelectric level upkeep operation described evaluator with
Distance between described radio-frequency (RF) tag:
During equipotential live line work, carry out as a example by pipe mother's livewire work by insulated flexible ladder, the letter read according to described evaluator
Breath and data, it is judged that the combinational gap between described evaluator and described grounding body and electrical body, if described combinational gap does not exists
In safety range, then send early warning information.Specifically, as it is shown on figure 3, described second pipe mother's wire 31 is provided with the second pipe mother and leads
Line label 32, described grounding body 33 is provided with grounding body label 34, and the evaluator that upkeep operation personnel 35 carry records maintenance and makees
The second distance of industry personnel 35 and the first distance d1 of second pipe mother's wire 31 and upkeep operation personnel 35 and described grounding body 33
D2, along with two distance value real-time change of change in location of upkeep operation personnel 35, wherein said first distance d1 and second away from
From d2's be combinational gap, say, that described combinational gap refers to the distance between described evaluator and described grounding body
With the spacing of described evaluator and described electrical body and.When described first distance d1 and second distance d2's and reach industry
During setting, described evaluator can send early warning information, it is to avoid step on charging equipment by mistake, so that it is guaranteed that the peace of upkeep operation personnel
Entirely, improve the safety of operation.
In the present embodiment, described early warning information alerts, by sounding or luminous arrival of described evaluator, the mesh indicated
, thus upkeep operation personnel can judge whether to be in deathtrap the most intuitively, it is ensured that and the safety of upkeep operation personnel, carry
The high safety of operation.
To sum up, technical scheme of the present invention has the advantage that
Substation equipment maintenance and repair operation location the most of the present invention and safe early warning method, in described step S1, in the different band of transformer station
