Description

An integrated video monitoring device for power distribution networks Technical Field

[0001] This invention relates to the field of line monitoring technology, and in particular to an integrated device for video monitoring of distribution networks. Background Technology

[0002] The power distribution network is complex and has huge monitoring needs. How to achieve high-quality, low-cost, and minimally manual line monitoring has always been an important issue in the power distribution network field. At the same time, with the continuous development of smart grids, it has become possible to monitor the real-time status of distribution network areas and central lines from multiple perspectives such as electrical, video, temperature and humidity.

[0003] Distribution network monitoring is a crucial component of the power system. Besides real-time monitoring of parameters such as current, voltage, frequency, and temperature within power lines, it also requires collecting image, environmental, and meteorological information about the surrounding area. However, existing monitoring methods rely on ground-based supports to mount sensors, enabling real-time acquisition of image and environmental data from distribution network sites. This approach lacks the ability to measure parameters like current, voltage, frequency, and temperature, resulting in incomplete information collection. Furthermore, the need for additional support structures increases monitoring costs and hinders subsequent maintenance.

[0004] Summary of the Invention

[0005] The present invention aims to provide an integrated video monitoring device for distribution networks to solve the above-mentioned technical problems, realize comprehensive monitoring of distribution network line status data, simplify the installation process, and reduce equipment and maintenance costs.

[0006] To address the aforementioned technical problems, this invention provides an integrated video monitoring device for power distribution networks, comprising a monitoring body, a power supply fixing ring disposed on the monitoring body, a sensor group disposed on the monitoring body, a camera assembly, and a control circuit disposed within the monitoring body; wherein:

[0007] The power-feeding fixing ring is used to fix the monitoring subject on the power distribution line to be monitored and to draw power, thereby supplying power to the control circuit and the camera component.

[0008] The sensor array is used to collect various types of status data and transmit them to the control circuit.

[0009] The signal terminal of the camera component is electrically connected to the control circuit to achieve information interaction; the camera component can realize wireless signal transmission, data transmission and camera control.

[0010] The device provided by the above solution only requires attaching the power-operated fixing ring to the cable of the distribution network line to be monitored to secure the monitoring subject. This allows for the collection of various types of status data from the sensor array and the acquisition of video and image data from the distribution network line, thus achieving comprehensive monitoring of the distribution network line's status. This device effectively simplifies the installation process and reduces equipment and maintenance costs.

[0011] In the above scheme, since the sensor group is installed within the monitoring unit, the installation process only requires pulling the sensors out of the monitoring unit and placing the probes at the monitoring points of the power distribution lines to collect data. The collected data is transmitted from the sensor group to the control circuit, and finally, the camera assembly enables remote data transmission. This process does not require the introduction of new equipment components, thus reducing monitoring costs.

[0012] It should be noted that, to ensure the long-term operation of the camera component, it can also be powered by a rechargeable battery.

[0013] Furthermore, the power-taking fixing ring includes a power-taking ring and an elastic clamp; wherein: the elastic clamp is used to snap onto the distribution network line to be monitored to fix the monitoring body; and to place the distribution network line to be monitored in the power-taking ring; the power-taking ring is used to draw power from the distribution network line to be monitored, thereby supplying power to the control circuit and the camera assembly.

[0014] In the above scheme, the installation process of the power collection fixing ring can be as follows: open the power collection ring and place the cable of the distribution network line to be monitored in the power collection ring, then open the elastic clamp so that the elastic clamp is snapped onto the cable, thereby stabilizing the connection between the power collection fixing ring and the cable, and finally close the power collection ring. The installation process does not require the cable to be de-energized.

[0015] Furthermore, the power-taking ring draws power from the distribution network line to be monitored via CT induction, which can ensure that the device operates / standby on the power supply line 24 hours a day, thereby optimizing the power supply method.

[0016] Furthermore, the sensor group includes an electrical sensor, a temperature sensor, and a humidity sensor; wherein: the electrical sensor is used to monitor the current and voltage values ​​of the distribution network line to be monitored and transmits the monitoring data to the control circuit; the temperature sensor is used to monitor the ambient temperature and transmits the monitoring data to the control circuit; the humidity sensor is used to monitor the ambient humidity and transmits the monitoring data to the control circuit.

[0017] In the above scheme, the sensor group can be set up according to the actual application requirements, and the corresponding sensors / data acquisition devices can be set up for the required multi-dimensional data to achieve comprehensive monitoring of power distribution lines.

[0018] Furthermore, the temperature sensor is an infrared temperature sensor.

[0019] Furthermore, the main control chip of the control circuit is a microcontroller control chip or an embedded control chip.

[0020] Furthermore, the camera assembly includes a rotating platform, a camera, and a wireless transmission module; wherein: the camera is fixed on the rotating platform, and the rotating platform is rotatably mounted on the monitoring body; the control terminal of the rotating platform is electrically connected to the output terminal of the control circuit; the wireless transmission module is electrically connected to the control circuit to realize information interaction; the control terminal of the camera is electrically connected to the output terminal of the control circuit; and the signal output terminal of the camera is electrically connected to the wireless transmission module.

[0021] In the above solution, the rotating platform can be remotely controlled via a wireless transmission module and control circuit, thereby adjusting the camera's shooting angle and enabling more comprehensive acquisition of image and video data. The camera component can act as a gateway within the device, requiring no additional equipment, simplifying wiring, and streamlining the structure of the integrated device. The wireless transmission module allows image and video data, along with data from sensors, to be wirelessly transmitted to the remote terminal.

[0022] It should be noted that the integrated video monitoring device for power distribution networks can act as an integrated fault indicator. When a short circuit or open circuit fault occurs in the line, the sensor group sends up fault information, and the camera assists in visually locating the fault location.

[0023] Furthermore, the camera is a wide-angle camera, and the wireless transmission module is a LoRa wireless transmission module.

[0024] Furthermore, the integrated power distribution network video monitoring device also includes a limiting protrusion, which is located at the connection between the monitoring body and the rotating platform. The limiting protrusion restricts the rotation angle of the camera, preventing damage to the camera due to excessive rotation of the rotating platform.

[0025] Furthermore, the wireless transmission module is equipped with an encryption unit; the encryption unit is used to encrypt the stored and transmitted data, and transmit the data in ciphertext form to improve the security of transmission. Attached Figure Description
