Based on intelligent substation robot cruising inspection system and transformer station's operation monitoring method thereof
Technical field
The present invention relates to a kind ofly, belong to automation of transformation substations control field based on intelligent substation robot cruising inspection system and transformer station thereof operation monitoring method.
Background technology
In transformer station, operate or during operation, no matter be normal operating grid switching operation, the accident treatment in still unusual generation the, or even on-the-spot plant maintenance maintenance all need the special messenger to carry out the monitoring of operation task.At normal power equipment grid switching operation, adopt the operation order system, during work, need the monitoring personnel to call out the names of those voted for while counting ballot-slips, the operating personnel operates according to the operation order content, and the monitoring personnel examine operating personnel's operation, implement with accurate with the safety that ensures operation.The monitoring personnel need more rich knowledge and experience, and field condition and job step are made judgement accurately.But and popularization few people on duty unattended along with transformer station, the operator on duty of transformer station is fewer and feweri.Existing security protection video system is because camera is installed negligible amounts, and the installation site is unreasonable, can not reach the requirement of long distance monitoring.If camera is installed in a large number, system cost is big and maintenance cost is too many.
For addressing the above problem, domestic and international many mechanisms have all carried out deep research to this, and main achievement in research comprises:
1, the patent No. of announcing in State Intellectual Property Office and on December 14th, 2,005 200410024231.2; Name is called and has proposed the technical scheme that an employing robot patrols and examines the converting equipment operation conditions automatically, the main automatic collection that realizes information such as device temperature in the transformer station and visible light videos of this invention in the patent of " distribution equipment intelligence automatic crusing robot ".
2, State Intellectual Property Office and on May 18th, 2011 bulletin the patent No. 201110002034.0, name is called and proposes will " intelligent video system " access to change control system in proper order in the patent of " transformer station that possesses visual and interactivity is along the control system " and replace original manual work affirmation.
Above-mentioned research has all obtained beneficial effect to a certain extent, but still has following problem:
1, " distribution equipment intelligence automatic crusing robot " do not propose to adopt corresponding monitoring method.
2, " possesses suitable control system of visual transformer station " though released the video check of suitable control operation with interactivity; But the video monitoring method of accident treatment and upkeep operation is not proposed; And " intelligent video system " of its use; Need image capture device to be installed at all device locations of transformer station; System complex is invested huge.
