[0031] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. The described embodiment is only a part of the embodiment of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of the present invention.

[0032] In one technical solution of the present invention, Figure 1 is a structural block diagram provided according to the specific structure of a high-voltage line protection early warning system of the present invention, such as Figure 1 As shown, the dotted line in the figure is a circuit line, which is implemented as a signal line. The present invention specifically includes: Multiple field-end devices and a cloud server 4, wherein the multiple field-end devices are all communicatively connected with the cloud server 4, wherein the field-end devices are installed at the high-voltage line site to monitor the high-voltage lines in the area and detect objects approaching. Multiple field-end devices are arranged for high-voltage line detection in different areas, and the field-end devices also have a positioning function so that the background server can quickly locate the abnormal area.

[0033] Among them, the on-site equipment includes: a detection unit 1, a monitoring unit 2, a positioning unit 3, a power generation unit 6, and an energy storage unit 5. The detection unit 1, the monitoring unit 2, and the positioning unit 3 are all communicatively connected to the cloud server 4, and the power generation unit 6 is connected to the energy storage unit 5.

[0034] The power generation unit 6 is used to generate electric energy by relying on wind power and solar energy, and the energy storage unit 5 is used to store electric energy and to supply power to the detection unit 1 , the monitoring unit 2 , and the positioning unit 3 respectively.

[0035] The power generation unit 6 includes a solar panel 61 and a wind turbine 62. The energy storage unit 5 includes an energy storage management device 51 and an energy storage battery 52. ​​The energy management device stores the electric energy generated by the power generation unit 6 in the energy storage battery 52 and provides the electric energy in the energy storage battery 52 to the detection unit 1, the monitoring unit 2, and the positioning unit 3.

[0036] The solar panel 61 converts solar energy into direct current, and the wind turbine 62 converts wind energy into electrical energy when there is wind. The electrical energy is transmitted to the energy storage battery 52 for storage, and the energy storage management device 51 manages and distributes the electrical energy in the energy storage battery 52 to provide stable power for all parts of the entire system. Among them, the energy storage management device 51 can specifically adopt JVM-MPPT20. High-voltage lines are often located in remote areas, and traditional power grid power supply may be difficult to cover or costly. The use of solar energy and wind power, two renewable energy sources, can achieve autonomous power supply, reduce dependence on external power grids, and improve system reliability and sustainability. The energy storage battery 52 and the energy storage module can ensure that the system has a stable power supply when solar energy and wind power are unstable.

[0037] The monitoring unit 2 is used to obtain real-time images of the high-voltage line. The monitoring camera is connected to the cloud server 4 through the HTTP protocol. The monitoring camera performs real-time video monitoring of the high-voltage line site and transmits the image data to the cloud server 4 via wired or wireless means.

[0038] The positioning unit 3 is used to obtain the location information of the high-voltage line, and the positioning unit 3 includes a locator, and the locator is connected to the cloud server 4 through the HTTP protocol. The locator can use Beidou positioning or GPS positioning, and specifically can use A7670E.

[0039] Surveillance cameras provide intuitive on-site images, helping managers understand the situation around high-voltage lines in real time, and provide detailed image information when potential threats or failures occur, making it easy to quickly determine the location and nature of the problem so that measures can be taken. Accurately determining the location of equipment is important for equipment management and maintenance. When a failure or maintenance occurs, the equipment can be quickly found to improve maintenance efficiency. Location information can also be used to analyze the environment around high-voltage lines to better plan and deploy early warning systems.

[0040] The detection unit 1 is used to detect an object approaching the high-voltage line, and generates a detection signal when an object is detected approaching the high-voltage line.

[0041] Among them, the detection module includes: a laser detector 11, a radar detector 12 and a control host 13. The laser detector 11 and the radar detector 12 are both communicatively connected to the control host 13. The laser detector 11 is used to detect the high-voltage line through laser, and the radar detector 12 is used to detect the high-voltage line through radar. The control host 13 can generate a detection signal when the laser detector 11 or the radar detector 12 detects that an object is approaching.

[0042] Specifically, the laser detector 11 can be of a counter-beam type, where the transmitter continuously emits a laser beam to the receiver. When an object blocks the laser beam, the receiver detects the signal change and transmits the information to the control host 13. The radar detector 12 can be of a counter-beam type, where the transmitter emits radar waves and the receiver receives radar waves. When the radar waves are reflected by an object, the receiver receives the reflected waves and transmits the data to the control module. The control host 13 analyzes and processes the laser and radar data to determine whether an object is approaching the high-voltage line and there is a potential threat to the high-voltage line. Specifically, the control host 13 can be: AL-9480G.

[0043] The laser detector 11 has high precision and strong sensitivity. It can detect even small foreign objects blocking the laser beam around the high-voltage line and detect potential dangers in time. The radar detector 12 can detect objects at a longer distance and is not affected by light and weather conditions. It can detect large or moving objects around the high-voltage line in time, provide information such as position and speed, and help the prevention and control module to make accurate judgments. The prevention and control host 13 is one of the core parts of the system. After receiving laser and radar data, it judges potential threats through preset algorithms and rules, and promptly issues warning signals or activates defense mechanisms to protect the safety of high-voltage lines.

[0044] The control host 13 is connected to the laser detector 11 and the radar detector 12 through the MQTT protocol, and is connected to the cloud server 4 through the HTTP protocol. The control host 13 is also connected to an audible and visual alarm, which is used to emit an audible and visual alarm.

[0045] The cloud server 4 is used for centrally managing the plurality of field-end devices and displaying corresponding real-time images and location information according to the detection signal.

[0046] More specifically, the cloud server 4 communicates with the field device through a switch to implement network communication of the HTTP protocol. The switch is a key device for data transmission, which can forward and route data from different devices to ensure that data is transmitted to the cloud server 4 quickly and accurately.

[0047] As the core data processing center, the cloud server 4 receives data from various field-end devices for comprehensive analysis and processing to achieve comprehensive management of various field-end devices and intelligent early warning of high-voltage lines. The cloud management platform runs in the cloud server 4, which also has the function of image recognition. Through video image recognition and analysis, it can automatically detect abnormal conditions around high-voltage lines. Combined with the comprehensive evaluation of location and prevention and control data, it can more comprehensively understand the safety situation and improve the accuracy and reliability of early warning.

[0048] It should be noted that the above-mentioned cloud management platform and image recognition functions are conventional technical means of the present invention, and this patent does not improve them, so they will not be elaborated on.

[0049] In another technical solution of the present invention, Figure 2 and Figure 3 A flowchart is provided according to a high-voltage line protection early warning method, wherein the method is applied to any of the above-mentioned high-voltage line protection early warning systems, including: The cloud server performs status inspection on the field equipment, and triggers the cloud server alarm when detecting abnormal status of the field equipment. The abnormal status detected by the field equipment includes: the equipment is offline, the equipment voltage is lower than 15V, and the equipment power is lower than 25%.

[0050] like Figure 2 As shown, the cloud server performs status inspection on the on-site equipment, specifically: The cloud server detects whether the on-site equipment is online. When the on-site equipment is offline, the cloud server alarms.

[0051] The cloud server detects the working voltage of the on-site equipment. When the equipment voltage is lower than 15V, the cloud server alarms.

[0052] The cloud server detects the power level of the on-site equipment. When the power level of the equipment is lower than 25%, the cloud server will alarm.

[0053] The on-site equipment detects objects approaching the high-voltage line through a detection unit. When an object is detected approaching the high-voltage line, the monitoring unit obtains the on-site image and sends it to the cloud server. The cloud server alarms and displays the on-site image.

[0054] like Figure 3 As shown, the detection process of the field equipment through the laser detector is as follows: The control host is initialized. When the laser detector is blocked for more than 20 seconds, it is judged as a brief intrusion. The camera saves the images 10 seconds before and after the current moment and transmits them to the cloud server, which then issues an alarm.

[0055] When the laser detector is blocked for more than 60 seconds, it is judged as a continuous intrusion. The camera saves the images 10 seconds before and after the current moment and transmits them to the cloud server, which then issues an alarm.

[0056] When the laser detector is blocked more than three times within 60 seconds, it is judged as repeated intrusion. The camera saves the images 10 seconds before and after the current moment and transmits them to the cloud server, which then issues an alarm.

[0057] The beneficial effects of this technical solution are the same as those of the high-voltage line protection early warning system, so they will not be repeated here.

[0058] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
