System, in daily tour, arranges the wrong potential safety hazard touching charging equipment in the work such as safety measure, is strayed into interval in power system
Touch charging equipment situation to take place frequently by mistake.During substation equipment maintenance and repair, maintainer is adjacent belts faced by during part interval has a power failure
Electricity interval only relies on artificial range estimation safe distance and is difficult to accurately, it is possible to cause maintainer and plant equipment generation electric shock thing
Therefore.External workmen, because of reasons such as duty are the best or is unfamiliar with plant stand, in daily tour, layout safety measure, shows
The wrong potential safety hazard touching charging equipment in the work such as field maintenance, in power system, similar accident event emerges in an endless stream.
Summary of the invention
For the deficiencies in the prior art, it is an object of the invention to provide a kind of transformer station fortune inspection working space three-dimensional security
Monitoring method, sets the area of safety operaton of transformer station's three-dimensional scenic, and personnel and equipment to site activity carry out real-time tracking
And monitoring, it is ensured that itself and the safe distance of charging equipment, and realize space intelligentization monitoring.
To achieve these goals, the present invention adopts the technical scheme that:
A kind of transformer station fortune inspection working space three-dimensional security monitoring method, including step:
Use three-dimensional laser scanner that the working region in transformer station is scanned, set up transformer station according to scanning result
Three-dimensional simulation model, and be illustrated in main website side monitoring device；
According to the different electric pressures of substation field power equipment, the three-dimensional simulation model of transformer station calibrates peace
Region-wide, alarm region and deathtrap；
Use staff and the positional information of plant equipment of wireless location technology Real-time Collection substation field operation,
And by location position in the three-dimensional simulation model of transformer station, when staff or plant equipment enter described alarm region or institute
When stating deathtrap, send alarm；

Real-time carrying out is observed and reports to the police.Improve the level of risk management of transformer substation operation safety, it is ensured that staff and plant equipment
Safety.Develop a set of transformer station maintenance activity space three-dimensional safety monitoring system, by Intelligent Video Surveillance Technology, space without
The mode that line monitoring technology, three-dimensional laser scanning technique combine, sets up the virtual spatial model of transformer station, demarcates safety operation area
Territory, monitoring staff's range of activity, the space safety distance of real-time monitoring results personnel, plant equipment and charging equipment, really
The production that ensures safety is smoothed out.
Accompanying drawing explanation
Fig. 1 is the schematic flow sheet of transformer station of the present invention fortune inspection working space three-dimensional security monitoring method.
Detailed description of the invention
Current during substation equipment maintenance and repair, artificial range estimation safe distance is difficult to accurately, it is possible to cause maintainer and machine
Tool equipment generation electric shock accidents.Therefore this Project-developing goes out a kind of can supervise the personnel of power transformation site activity and equipment in real time
Survey and the intelligent monitor system of security alarm, to guarantee its safety work.
The present invention sets the area of safety operaton of transformer station's three-dimensional scenic, and on this basis, the personnel to site activity
Carry out real-time tracking and monitoring with equipment, it is ensured that itself and the safe distance of charging equipment, and be different from the peace that conventional operation is on-the-spot
Full monitor mode, it is achieved space intelligentization is monitored.The concrete grammar of the present invention is described below.
As it is shown in figure 1, transformer station of the present invention fortune inspection working space three-dimensional security monitoring method, including step:
Working region in transformer station is scanned, according to scanning result by step s101, employing three-dimensional laser scanner
Set up the three-dimensional simulation model of transformer station, and be illustrated in main website side monitoring device；
Step s102, different electric pressures according to substation field power equipment, at the three-dimensional simulation model of transformer station
In calibrate safety zone, alarm region and deathtrap.
Step s103, the staff using wireless location technology Real-time Collection substation field operation and plant equipment
Positional information, and by location position in the three-dimensional simulation model of transformer station, when staff or plant equipment enter described report
When police region territory or described deathtrap, send alarm.
Arrange multiple signal receiving devices at operation field, require that staff and plant equipment carry transmitting signal simultaneously
Label.Wireless location system receives the signal that label is launched, and determines label position by signal analysis, and is sent to main in real time
Stand side monitoring personnel.This label position is calibrated in virtual 3D scene simultaneously, and to entering deathtrap and alarm region
Follow the tracks of target and propose warning message.Staff and plant equipment can also receive the data that main website side monitoring device sends,
Thus obtain the positional information of himself and surrounding.
The field operation of step s104, employing Video Supervision Technique Real-time Collection work of transformer substation personnel and plant equipment is drawn
Face, and it is uploaded to main website side monitoring device.
The positional information collected according to framing signal to diverse location camera acquisition to image process.Not only
Can the field condition of monitoring in real time, moreover it is possible on the basis of the threedimensional model of simulation tracing target, build real-time monitored space
Three-dimensional scenic, the tracking target in monitoring region.
In order to carry out overhaul management, by setting up record of examination tables of data for depositing record of examination.Work as station
When personnel carry out line maintenance, maintenance path monitoring device acquired is stored with the form of three-dimensional coordinate by time series
In log, it is simple to the management of overhaul data and maintenance.
To sum up, this method have employed three-dimensional laser scanning technique, spacing wireless monitoring technology and Intelligent Video Surveillance Technology.
Utilize laser scanner technique can collect three-dimensional space data quickly and accurately, three-dimensional laser measuring instrument is installed, can use
The method of pulsed laser ranging, the digital virtual model of operation field is set up in subregion scanning.One or more signals are installed launch
Device, operating personnel, plant equipment carry signal reception, reflection unit, by powerful signal analysis platform to reception
To information be analyzed process, know the three-dimensional spatial information of personnel, monitoring personnel are in the space operation of working site
Track.
This method is effectively improved the personal safety of execute-in-place operation maintenance personnel, and has ensured that power equipment and construction set
Standby safe handling, improves stability and the reliability of substation operation, decreases unnecessary security incident and property loss,
Thus this method has higher economic benefit and practical value.
