Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic new energy, and particularly relates to a wire-type wildfire monitoring device for a photovoltaic power collection line. Background Art

[0002] With the rapid development of the photovoltaic new energy power generation industry, the outgoing lines and power collection lines of photovoltaic power stations are also facing increasing operation and maintenance pressures. The construction and maintenance of photovoltaic power collection lines require a large number of intelligent devices to ensure their safe operation. Wire-type wildfire monitoring of photovoltaic power collection lines is an important power grid safety protection measure, aiming to monitor the photovoltaic power collection lines in real time and warn of wildfire risks to ensure the safe and stable operation of transmission lines. With the rapid development of photovoltaic new energy, the threat of wildfires to power collection lines is also increasing day by day. Due to the large number of trees in mountainous and forested areas, the fire spreads relatively quickly and the temperature is relatively high, which easily endangers the transmission lines in this area, causing the lines to trip and, in severe cases, burning the lines. In traditional wildfire monitoring systems, cameras or infrared flame detectors are mostly used for wildfire monitoring. In this monitoring method, the camera needs to work for a long time, consuming a large amount of energy. Moreover, the camera is exposed outdoors all year round, so that the camera will be eroded by wind and rain. This not only may cause dirt and water stains on the lens, resulting in blurred images and requiring regular cleaning to keep the images clear, but also may affect its stability and normal operation. At the same time, the infrared flame detector can only detect open flames and cannot detect fire hazards in time. The traditional monitoring method cannot meet the requirements of real-time and accuracy. Content of the Utility Model

[0003] The utility model provides a wire-type wildfire monitoring device for a photovoltaic power collection line, which can monitor the photovoltaic power collection line in real time, can detect fire hazards in time, and avoid the long-term exposure of visible light cameras outdoors.

[0004] In order to achieve the above object, the present application provides the following technical solutions:

[0005] A wire-type wildfire monitoring device for a photovoltaic power collection line includes a controller, a power supply module, a sensor module, a network communication module, a cloud server, and a remote monitoring server;

[0006] The power supply module, the sensor module, and the network communication module are all electrically connected to the controller;

[0007] The sensor module includes an infrared camera, a visible light camera, and a temperature and humidity sensor;

[0008] The infrared camera collects thermal imaging image data of the environment and feeds back a thermal imaging image signal to the controller;

[0009] The temperature and humidity sensor detects the temperature and humidity data of the environment and feeds back the temperature and humidity detection signal to the controller;

[0010] It further includes a device body, and the device body includes an installation box and a driving mechanism;

[0011] An extension opening is provided on the installation box, the driving mechanism is arranged inside the installation box, the driving end of the driving mechanism is connected to the visible light camera, and the driving mechanism can drive the visible light camera to extend out of the installation box through the extension opening;

[0012] The visible light camera collects the visible light image data of the environment and feeds back the visible light image signal to the controller;

[0013] The controller controls the opening and closing of the driving mechanism and the visible light camera according to the thermal imaging image signal and the temperature and humidity detection signal;

[0014] The controller sends the thermal imaging image signal, the temperature and humidity detection signal and the visible light image signal to the cloud server through the network communication module, and data transmission between the controller and the remote monitoring server is carried out through the cloud server.

[0015] The principle and advantages of the present utility model are as follows:

[0016] Integrating an infrared camera, a visible light camera and a temperature and humidity sensor, the main purpose of this integrated design is to improve the real-time performance and accuracy of the monitoring system. By integrating multiple sensors, data can be obtained in different bands and different environmental conditions to ensure the comprehensiveness of monitoring and be able to detect fire hazards in a timely manner; in the monitoring of photovoltaic power collection lines, wildfire monitoring is an important application scenario. Since these areas are usually located in remote or natural environments with complex conditions, the integrated monitoring device can effectively improve the monitoring efficiency and response speed, which is crucial for preventing the spread of fires;

[0017] The controller controls the opening and closing of the visible light camera according to the thermal imaging image signal and the temperature and humidity detection signal. Based on the fusion analysis of the infrared thermal imaging and the environmental temperature and humidity data, the hot spot information captured by the infrared thermal imaging technology is combined with the environmental temperature and humidity data, which helps to reduce false alarms. For example, by identifying that although the temperature is high but the humidity is high, the situation may not pose a fire risk, thus improving the accuracy of the alarm and being able to detect fire hazards in a timely manner; according to the thermal imaging image signal and the temperature and humidity detection signal, the opening and closing of the visible light camera can be accurately controlled, which not only reduces unnecessary energy consumption but also extends the service life of the device. The visible light image data is collected to directly view the on-site environment, and the visible light image provides direct on-site visual information for the operation and maintenance personnel. This intuitive information is very crucial for the rapid assessment of the on-site situation and decision-making;

[0018] The controller controls the driving mechanism to drive the visible light camera to extend or retract into the installation box according to the thermal imaging image signal and the temperature and humidity detection signal. When it is necessary to collect visible light image data of the environment, the visible light camera is turned on when it extends out of the installation box. When it is not necessary to collect visible light image data of the environment, the visible light camera is turned off when it retracts into the installation box, which can avoid being eroded by wind and rain, prevent dirt and water stains from appearing on the lens, resulting in blurred images, and prevent dust, moisture and other corrosive substances from eroding. It is especially suitable for outdoor or harsh environments.

A second sliding groove is formed on the left side wall of the second sliding frame. The second rack is slidably sleeved in the second sliding groove along the front and rear directions. The rear end of the second rack penetrates through the rear side wall of the installation box and extends out of the installation box, and is slidably sleeved on the rear side wall of the installation box. The left side of the second rack meshes with the second gear. The mounting plate is fixedly connected to the front end of the second rack. The visible light camera is fixedly installed on the mounting plate;

[0024] The micro motor is electrically connected to the controller. The controller controls the opening and closing of the micro motor and the visible light camera according to the thermal imaging image signal and the temperature and humidity detection signal.

At the same time, the micro motor drives the first gear to rotate, driving the first rack to move to the right, driving the baffle to seal the outlet. After the visible light camera is retracted into the installation box, the installation box can be closed and sealed to prevent dust, moisture, and other corrosive substances from eroding, especially suitable for outdoor or harsh environments;

[0026] According to the thermal imaging image signal and the temperature and humidity detection signal, when it is necessary to collect visible light image data of the environment, the controller drives the second gear to rotate in the reverse direction again, driving the second rack to move forward, driving the visible light camera to extend forward out of the installation box. At the same time, the micro motor drives the first gear to rotate synchronously in the reverse direction, driving the first rack to move to the left, driving the baffle to slide to the left to open the outlet, facilitating the visible light camera to extend out of the installation box. At the same time, the controller starts the visible light camera to collect visible light image data of the environment.

[0027] Furthermore, the power supply module includes a storage battery and a solar power supply module.

[0028] Beneficial effects: Through the combined power supply of the storage battery and the solar module, the solar power supply module converts solar energy into electrical energy, providing an environmentally friendly and sustainable energy acquisition method for the monitoring system.

[0035] Beneficial effects: When the infrared camera detects an abnormal temperature rise, the smoke sensor can further confirm whether there is smoke generated, so as to more accurately identify the wildfire risk; smoke sensors usually have high sensitivity and can quickly respond to the presence of smoke. This is particularly important for wildfire monitoring, because early detection can significantly reduce the risk of fire spread. Combining temperature and humidity data with smoke data can more accurately determine the location and intensity of the fire source.

[0036] Further, it includes a timer module, the timer module is electrically connected to the controller, and the controller controls the sensor module to detect environmental data according to the signal of the timer module.

[0037] Beneficial effects: The controller controls the detection frequency of the sensor module through the timer module, preventing the sensor module from having too many invalid detection operations due to too fast detection frequency, and reducing energy consumption.
