Detailed ways

In order to better understand the technical solutions of the present utility model, the following specific examples are described in detail:

The utility model relates to an integrated sensing terminal system for a power distribution room, which comprises an integrated sensing terminal arranged in the power distribution room, an operation and maintenance monitoring background and an interactive terminal.

Referring to FIG. 1 , the integrated sensing terminal includes an integrated sensing head 1 and a bracket for supporting the integrated sensing head. An infrared thermal imaging camera 11 and a visible light camera 12 are respectively provided on the front surface of the integrated sensing head 1 , and a signal antenna 13 for PD signal monitoring is provided on the top of the integrated sensing head 1 . The above three sensing components constitute the most important three sensing devices of the integrated sensing terminal.

Among them, partial discharge signal monitoring is based on the partial discharge signal analysis and diagnosis algorithm of deep convolutional network, which realizes the accurate identification of partial discharge type and typical interference. Deep convolutional networks (CNN) have made breakthroughs in the field of image recognition, especially in large image processing. The PRPD maps and PRPS data commonly used in partial discharge detection and analysis are essentially two-dimensional matrices with large sizes. It has a certain similarity with the data format of digital images. In addition, due to the influence of field conditions, the data in this matrix will also have phase shifts and different amplitudes, while the deep convolutional network has the translation of input samples. , scaling, and distortion invariance. Therefore, the project uses a CNN-based deep learning model to identify and diagnose partial discharge data.

Infrared signal monitoring includes image overheating equipment, feature area extraction of components, area temperature detection and abnormal warning. First, establish a data set containing multiple power equipment images, and label the power equipment contained in each power equipment image, and use this as input to train the neural network and Bayesian network; use the trained neural network to treat The recognized power equipment images are recognized, and multiple recognition results are output; the trained Bayesian network is used to screen the recognition results of the neural network, and the most accurate recognition results corresponding to the power equipment images to be recognized are screened out.

Visible light signal monitoring is based on the video image anomaly detection algorithm based on fast regional convolutional neural network and mixed Gaussian model, which realizes the automatic identification of foreign body intrusion, personnel tracking and safety hazards in power distribution rooms. The invasion of small animals, garbage, kites, drones and other foreign objects in the power distribution room and the entry of personnel into the security warning area may often cause equipment failure and personal accidents. The harm should not be underestimated. It is impossible to predict when it will happen. The recognition algorithm of foreign objects in video images based on Faster Regional Convolutional Neural Network (Faster-RCNN) realizes real-time detection and real-time alarm of foreign objects intrusion in power distribution rooms, which has the advantages of high accuracy and fast recognition speed. The Gaussian Mixture Model (GMM) is used to track and detect intruders and objects. The principle is to establish multiple Gaussian models for each pixel point, and predict the several states of the pixel points that may appear tiny rhythms. When the background appears When there is a small change, it still conforms to a Gaussian model, so as to exclude small external disturbances. The algorithm is mainly used in the extraction of moving targets in a fixed background, and has strong anti-interference ability to slight external disturbances. In addition, the front end surface of the integrated sensing head 1 is provided with a fill light 14, which is used to fill the monitoring area when the brightness of the external environment is insufficient during the 24-hour visible light signal monitoring.

See Figure 2. The back of the integrated sensing head 1 is also provided with a temperature sensor 15 and a humidity sensor 16 to monitor the environmental status of the monitoring area in real time. The bottom of the integrated sensing head 1 is provided with a communication interface, which is used to connect with the private power network. The integrated sensing head 1 is also provided with a working status indicator light 17. When an abnormality is found in monitoring, it can be prompted by lights of different colors, so that the on-site inspection personnel can quickly locate the abnormal point. The integrated sensing terminal is powered by 220v power supply or POE. Each integrated sensing terminal is connected to the operation and maintenance monitoring background through the power intranet, and the operation and maintenance monitoring background is connected to each interactive terminal. The interactive terminal can be the tablet or smartphone of the on-site operation and maintenance personnel, so that the inspection personnel can quickly locate the abnormal point for quick maintenance; it can also be the web version of the PC or the data center platform of the software version, so that the operation and maintenance personnel can monitor the overall situation.
