Description
Technical Field
The invention belongs to the technical field of power systems, and particularly relates to an intelligent monitoring system for a transformer area terminal.
Background
The outdoor transformer is an extremely important environment in the link of the whole power distribution network, and in windy and rainy days, linear short-circuit objects fall between two phases to cause line short circuit and lead to damage of a line fuse. Based on this phenomenon, manual inspection is a work often faced by power workers, including periodic inspection, special inspection, night inspection, fault inspection, and pole-climbing inspection. Wherein, regular inspection is also called normal inspection, and through regular inspection of transformer platform district, can discover the problem to in time solve the problem, usually for patrolling and examining once at least every month. The special inspection refers to the inspection of the line after a disaster condition occurs. Night patrol is to inspect the defects of the wire connector and the insulator. The fault inspection means that when a line has a fault, fault inspection needs to be performed immediately to find out the cause of the fault and repair the line in time. When the parts at the upper part of a higher tower are not clear or are in doubt in ground inspection, the pole climbing inspection needs to be carried out.
However, manual inspection cannot monitor a transformer area for 24 hours, inspection cannot be performed in severe weather conditions, a fault occurrence point cannot be judged in advance when a fault occurs, timely treatment cannot be performed after the fault occurs, and emergency repair can be performed only by checking the fault occurrence position. Night inspection is also very dangerous to workers because night light is not as good as daytime, but many abnormal situations such as the phenomenon that the load is too large and the connector burns red require inspection at night. The pole climbing inspection also requires a worker to climb the pole for inspection, and is not safe and labor-saving.
Therefore, it is meaningful to provide an intelligent system which can replace workers to inspect and monitor transformer areas.

The image information marked with the classification label is used as a training data set, the training data set is used for training the classification neural network to obtain a learning classification model, and the specific training method is the existing classification model training method and is not detailed herein.
It should be noted that, when training the learning classification model, the more label data is input, the higher the data quality is, the better the final model is, the more feature memory is given to the target, the higher the recognition rate of the target is, and the image recognition capability of different scenes and different angles can be handled. In order to obtain more label data, image information of a target area under different scenes needs to be acquired, most of camera installation in the existing monitoring system is fixedly installed, the whole monitoring area is monitored, under the condition, a training data set needs to be acquired by adopting a mode of manual shooting or unmanned aerial vehicle shooting, on one hand, the cost of acquiring the training data set is high, on the other hand, due to the fact that image information of the target area under different scenes (such as bad weather of wind blowing, rain, snow and the like and light influence generated by rising and falling of the day) needs to be acquired, great influence can be generated on manual shooting or unmanned aerial vehicle shooting under the bad weather of rain, snow and the like, and the danger is high.
The transformer station area terminal intelligent monitoring system is provided with the rotatable telescopic mounting support, can rotate and stretch through the remote control, can remotely adjust the shooting angle of the camera, deals with various emergency conditions of the power distribution rack (for example, the situation that the camera is shielded by objects such as branches), improves the acquisition efficiency of the training data set, and provides a more effective scheme for acquiring the training data set of the learning classification model.
In this embodiment, the classification result obtained by the image detection unit 202 by the image information includes: normal fuses and fault fuses. If the classified result is a faulty fuse, the alarm processing unit 203 generates an alarm signal, and then transmits the alarm signal to the monitoring terminal through the communication unit 204. And the maintenance personnel in the power distribution station area process the abnormal conditions according to the alarm signal.
Optionally, the communication unit 204 is a TTU interface module, and the monitoring terminal may be a power grid TTU or a monitoring client.
In the intelligent monitoring system for the transformer station terminal of the embodiment, the image acquisition device 1 is arranged and used for acquiring image information of a target area in real time, the data processing chip 2 processes the received image information according to a preset learning classification model to obtain a classification result, generates an alarm signal according to the classification result and transmits the alarm signal to the monitoring terminal. The monitoring system can pre-judge the position of a fault in advance, and after the fault occurs, rush repair personnel can directly go to the fault occurrence point to carry out rush repair operation, the monitoring system has timeliness and promptness, all abnormity occurring in a transformer area can be monitored in 24 hours, and the insecurity of the personnel in night patrol is avoided.
The intelligent monitoring system for the transformer area terminal is provided with a learning classification model which is trained in advance, image information collected in real time in the transformer area is processed according to the preset learning classification model to obtain a classification result, an alarm signal is generated according to the classification result, and the alarm signal is transmitted to the monitoring terminal through the communication interface. The monitoring system only needs to effectively combine the connecting network TTU and the communication network without adding a special communication network or depending on a monitored site, does not need huge flow charge, only needs to upload abnormal event types and corresponding pictures, and has low flow consumption.
