Description
Technical field
The present invention relates to a kind of converter station status of electric power visually to screen inspection method.
Background technique
Converter valve can generate amount of heat when running, and dedicated valve cooling system is needed to radiate it.Converter valve is to work
The requirement for making environment is also very high, and dedicated HVAC system is needed to keep the constant of temperature in valve hall, humidity and pressure.HVAC system
System failure will lead to valve hall environmental degradation, jeopardize converter valve safety；And valve cooling system catastrophe failure can export tripping.Therefore,
Operation maintenance personnel will pay close attention to power equipment operating status more in daily tour, discovery in time and elimination hidden trouble of equipment.
Soft straight converter station power equipment has used a large amount of PLC and relay, each indicator light under equipment difference operating status
Display situation it is also not identical, therefore the state of indicator light can not be intuitively embodied by modes such as red dot, labels, it is necessary to according to
Current device operating condition ability analysis ratiocination goes out the correct status of indicator light on each PLC and relay.Therefore, under normal conditions
Operation maintenance personnel can only be abnormal by the message discovering device of error listing.
Summary of the invention
In view of this, the purpose of the present invention is to provide a kind of converter station power equipment equipment states visually to screen tour side
Method identifies indicator light with the image recognition algorithm of optimization and quickly judges whether each indicator light has exception, and discovery is set in time
Standby early stage hidden danger guarantees system safety.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of converter station status of electric power visually screens inspection method, provides mobile terminal and visual discrimination system, including following
Step:
Step S1: screen cabinet belonging to the operating condition, facility information, equipment by equipment, refers to the indicator light operating parameter in screen cabinet
Show lamp position set and each operating condition under shield instruction lamp on/off situation typing in cabinet to visual discrimination system；
Step S2: mobile terminal acquires the current operating condition of equipment to be maked an inspection tour, and is sent to visual discrimination system；
Step S3: visual discrimination system is according to the instruction shielded in cabinet under the current operating condition of equipment to be maked an inspection tour and each operating condition
Lamp on/off situation obtains the indicator light standard light on and off situation wait make an inspection tour in screen cabinet belonging to equipment；
Step S4: mobile terminal acquisition is described wait make an inspection tour the indicator light current image data for shielding cabinet belonging to equipment, and is sent to visual
Discrimination system；

Step S542: first dot coordinate of the first row is read, the coordinate is saved, and is set as the first row indicator light coordinate reference
Point；
Step S543: read the next dot coordinate of current row, judge the Y axis coordinate with refer to dot Y axis coordinate difference whether
Less than threshold value；If being less than threshold value, illustrate next dot and with reference to dot in same a line, enter step S544, otherwise, saves
Next dot coordinate, and it is set as next line indicator light coordinate reference points, return step S542；
Step S544: calculate next dot with reference to dot in the X-axis direction at a distance from；
Step S545: judge the distance whether the integral multiple for being d；If the integral multiple of d, then the dot coordinate is effective, and saving should
Coordinate, and the dot coordinate is set as coordinate reference points；Otherwise the origin is invalid；
Step S546: continuing to obtain next dot coordinate, until all adjacent dot coordinate distance judgements are completed.
The beneficial effect is that: the above method has filtered out a large amount of interference data, the large area white of such as reflective formation
Region or border circular areas are effectively reduced operand, realize the quick discrimination of indicator light coordinate.Suitable in mobile terminal list
Machine operation, meeting converter station etc. can only the application scenarios demand that cannot network of single-unit operation.
Further, in the step S52, picture is sheared according to the profile of drafting and is specifically included: judging the quadrangle
It whether is rectangle, if so, shearing picture along rectangular profile；If it is not, the quadrangle is then stretched as rectangle, and zoom to pre-
If shearing picture along profile after size.
Further, the visual discrimination system includes data acquisition unit, data analysis and processing unit and communication unit；
The data analysis and processing unit is separately connected with data acquisition unit and communication unit.
Further, screen cabinet ID is established, the operation that cabinet ID will be shielded, shield the facility information shown in cabinet, shield each equipment in cabinet
Operating condition, the indicator light operating parameter of each operating condition and indicator light coordinate information correspond and typing, obtains each operating condition
Instruction lamp on/off situation in lower screen cabinet.
Compared with the prior art, the invention has the following beneficial effects:
The present invention can calculate automatically the actual conditions of indicator light in each screen cabinet according to the current operating condition of equipment to be maked an inspection tour, and
According to the live image that mobile terminal acquires, identify that quickly judgement is each to indicator light by using the image recognition algorithm of optimization
Whether indicator light has exception, and timely discovering device early stage hidden danger guarantees power equipment safety.
