Problems solved by technology

[0006] The purpose of the present invention is to provide a personnel identification and monitoring system in the cable tunnel, which solves the problem that the existing substation monitoring system cannot identify the outsiders who have entered by mistake without fingerprint identification, and the monitoring results and video information are not transmitted to the host computer in real time At the same time, the management and control system for outsiders in the power system cannot track outsiders who enter the workplace. It can only monitor outsiders who have registered and received temporary labels. The problem of not being able to effectively track outsiders

Embodiment 1

[0051] Personnel identification and monitoring system in the cable tunnel, including ARM10 processor and Megvii, Face++ face recognition module connected to the processor, C417M-D communication module, tracking module and D203S pyroelectric infrared sensor detection module;

[0052] Processor: Accept the trigger signal sent by the pyroelectric infrared sensor detection module, start the face detection module after receiving the trigger signal; accept the intrusion signal sent by the face recognition module, and start the tracking module after receiving the intrusion signal;

[0053] Face recognition module: collect images of cable tunnels, judge whether there is a face in the image, and when a face appears, perform face recognition to judge whether it is the face image of a tunnel worker, if it is a face image of a tunnel worker image, the module enters dormancy, if it is not a face image of a tunnel worker, the face recognition module sends an intrusion signal to the processor...

Embodiment 2

[0059] The difference between this embodiment and Embodiment 1 is that the face recognition module includes an image acquisition unit, a face detection unit, a feature extraction unit and a feature matching unit;

[0060] Image acquisition unit: collect video images in the tunnel, and send the video images to the face detection unit;

[0061] Face detection unit: detect whether there is a human face in the image collected by the image acquisition unit, and send the face image to the feature extraction unit;

[0062] Feature extraction unit: the feature extraction unit extracts the facial features of the face image to generate the feature vector of the face;

[0063] Feature matching unit: The feature vector extracted by the feature extraction unit of the machine is matched with the pre-entered facial feature vector of the tunnel worker, and the matching similarity result is output. When the similarity is greater than the set threshold, the face recognition module is controlled...

Embodiment 3

[0075] A method for identifying and monitoring personnel in a cable tunnel, comprising the following steps:

[0076] A. Install the pyroelectric infrared sensor detection module in the tunnel, set the trigger wavelength range of the pyroelectric infrared sensor detection module, connect the tracking module to the tunnel robot, and start the system;

[0077] B. The pyroelectric infrared sensor detection module continuously monitors the tunnel to determine whether there is an infrared source within the trigger wavelength range in the tunnel. When there is an infrared source within the trigger wavelength range, enter step C. If there is no trigger wavelength range When the infrared source inside, repeat step B;

[0078] C. The face recognition module starts, collects images in the tunnel, and judges whether the intruder is a tunnel worker. If it is a tunnel worker, go to step B. If not, go to step D;

[0079] D. The tracking module starts, and the tracking module controls the tu...

Abstract

The invention discloses a personnel identification monitoring system in a cable tunnel, characterized in that a processor receives detection information of the pyroelectric infrared sensor detection module; when a person is detected, the processor sends information to the face recognition module, the face recognition module starts to work, collected images are processed, images containing faces are subjected to feature extraction and then compared with image feature vectors in a system database, and a matching result is sent to the processor; and the processor executes the next work accordingto the result, if the work is a tunnel worker, the work is normal, and if the work is a foreign person, the alarm information is sent to the upper computer and instruction information is sent to the tracking module; the tracking module starts to work, and the alarm starts to work to remind that the foreign persons break through via the detection information of the ultrasonic sensor and send the collected video information to the upper computer on line.

Description

technical field [0001] The invention relates to the field of monitoring equipment, in particular to a personnel identification and monitoring system in a cable tunnel. Background technique [0002] With the development of society, electricity has become an indispensable part of our life. As the main way of power transmission, the protection of cables is very important. The power tunnel is used to accommodate a large number of cables laid on the cable support. The existence of the cable tunnel not only protects the cables, but also improves the convenience of cable maintenance and repair. Due to the importance of the cable tunnel, it is very necessary to prevent non-staff personnel from entering the tunnel, causing damage to the cable and preventing casualties from entering the cable tunnel by mistake. [0003] Existing solutions include: substation monitoring system: composed of fingerprint module, processing equipment, camera module, alarm module and storage module. The f...
