Description

Technical Field

[0001] The present invention belongs to the field of security monitoring, and in particular relates to a monitoring system combining a remote network monitoring camera and a drone, for realizing remote and mobile monitoring. Background Art

[0002] Current remote monitoring technology mainly relies on fixed-mounted network cameras to achieve real-time monitoring and video playback through remote devices. Although the monitoring range can be expanded through pan-tilt control and multi-camera combination, the fixed nature of the camera limits the flexibility of monitoring. On the other hand, drones can provide a wider monitoring perspective, but the operation is complicated and limited by the signal distance, making it difficult to achieve long-term fixed-point monitoring. Therefore, there is an urgent need to develop a new monitoring system that can combine the advantages of fixed monitoring and mobile monitoring. Summary of the invention

[0003] In view of the above-mentioned defects of the prior art, the object of the present invention is to provide a remote monitoring system combining aerial monitoring by drones and ground monitoring by surveillance cameras, comprising:

[0004] The drone cabin includes a drone placement cabin and a drone parking platform. The drone placement cabin has an openable and closable cabin body. When the openable and closable cabin body is opened, the space above the drone parking platform is opened to form a flight space for the drone to take off and land.

[0005] The drone is placed in the drone placement cabin and on the drone parking platform when stopped, and takes off or lands from the drone parking platform through the flight space when taking off or landing. The drone includes a drone body and a camera module and a wireless communication module integrated on the drone body;

[0006] A surveillance camera, comprising a surveillance module, an interactive module, a wireless network module, a data processing module, and a power module;

[0009] The drone, surveillance camera, drone cabin, server and terminal equipment are connected through signals, and the drone cabin and surveillance camera are connected through interactive module signals;

[0010] When the drone is in flight, the drone cabin transmits the drone flight signal to the surveillance camera through the interactive module. The communication method between the drone and the surveillance camera or server is narrowband transmission;

[0011] When the drone lands on the drone parking platform, the drone cabin transmits the drone landing signal to the monitoring camera through the interactive module. The communication method between the drone and the monitoring camera or server is broadband transmission, or data is directly transmitted through a data cable.

[0012] Preferably, the wireless network module includes at least one of 4G, 5G, WiFi, and Bluetooth, and the power supply module includes at least one of a solar cell, a storage battery, and a plug-in cord.

[0013] Preferably, the surveillance camera further comprises a control pan / tilt, which is connected to a zoom lens, which can change the focal length. The zoom lens can change the shooting range by changing the focal length without changing the shooting distance.

[0014] Preferably, the UAV cabin is fixedly connected to the top of the monitoring camera or the UAV cabin and the monitoring camera are arranged separately, and the cabin body is made of waterproof material.

[0015] Preferably, the drone parking platform is provided with a charging device for charging the drone.

[0016] Preferably, the drone also includes a video compression module for compressing video data transmitted by the drone in flight to reduce the amount of data transmission.

[0023] It should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme of the present invention are shown in the drawings, while other details that are not closely related to the present invention are omitted.

[0024] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0025] Example:

[0026] like Figure 1-2 As shown, a remote monitoring system combining aerial monitoring of a drone and ground monitoring of a surveillance camera comprises: a drone cabin 300, including a drone placement cabin 310 and a drone parking platform, wherein the drone placement cabin 310 has an openable and closable cabin body, and when the openable and closable cabin body is opened, the space above the drone parking platform is opened to form a flight space for the drone to take off and land;

[0027] The drone 200 is placed in the drone placement cabin and on the drone parking platform when stopped, and takes off or lands from the drone parking platform through the flight space when taking off or landing. The drone 200 includes a drone body and a camera module 210 and a wireless communication module 220 integrated on the drone body;

[0028] The surveillance camera 100 includes a surveillance module 110, an interaction module 120, a wireless network module 130 and a power module 140;

[0029] The server 400 receives or sends transmission signals from the drone 200, the drone cabin 300, the monitoring camera 100 and the terminal device 500, and stores the video data transmitted by the monitoring camera 100 and / or the drone 200;

[0030] The terminal device 500 is used to display the video images captured by the drone 200 and / or the surveillance camera 100, and input operation instructions to the drone 200 and / or the surveillance camera 100. The specific terminal device 500 can be a smart phone or a computer. The user can send operation instructions such as take-off, landing, steering, acceleration of the drone 200 and monitoring angle of the surveillance camera 100 through a dedicated application or web interface. ;

[0031] The drone 200, the surveillance camera 100, the drone cabin 300, the server 400 and the terminal device 500 are connected via signals.

[0032] The wireless network module 130 includes at least one of 4G, 5G, WiFi, and Bluetooth, and the power module 140 includes at least one of a solar cell, a storage battery, and a plug-in cord.

[0033] In this embodiment, the monitoring camera 100 also includes a control pan-tilt head 150, which is connected to a zoom lens. The zoom lens can change the focal length. The zoom lens can change the shooting range by changing the focal length without changing the shooting distance. At the same time, the control pan-tilt head 150 can also rotate left and right or up and down to adjust the monitoring viewing angle, thereby achieving the effect of multi-directional and multi-screen monitoring functions.

[0034] like Figure 1 As shown, the drone cabin 300 is fixedly connected to the top of the monitoring camera 100. Of course, in other embodiments, the drone cabin 300 and the monitoring camera 100 can also be connected in a split manner. The cabin is made of waterproof material to prevent water from entering the equipment and causing damage.

[0035] Furthermore, the drone parking platform is provided with a charging device for charging the drone 200, which may specifically be an invalid charging device, a charging socket, a charging contact, etc.

[0036] In this embodiment, when the drone 200 is in flight, the video data transmission between the drone 200 and the surveillance camera 100 adopts a narrowband transmission method, such as a narrowband Internet of Things (NB-IoT) or a narrowband long-distance communication (NB-LTE) method. The transmission method is designed for low power consumption and long-distance communication, and is suitable for the drone 200 to perform stable video transmission in a wide area.

[0037] Narrowband transmission helps reduce power consumption and improve signal penetration, thus enabling long-distance communication.

[0038] In order to efficiently transmit video data under narrowband conditions, the drone also includes a video compression module 230. The video compression module 230 can use encoding such as H.265 / HEVC (High Efficiency Video Coding) to significantly reduce the amount of data while ensuring video quality.

[0039] The compressed video data is transmitted in real time to the surveillance camera 100 or the server 400 through the wireless communication module 220 of the drone 200, and is pushed to the user's terminal device 500 in real time. During the entire transmission process, appropriate error correction and retransmission mechanisms are used to ensure the reliability of video transmission.

[0040] According to the network conditions and the flight environment of the drone 200, the system can dynamically adjust the video compression rate and transmission parameters to achieve the best transmission effect under different conditions. For example, in the case of weak signal strength or network congestion, the system can reduce the video resolution or frame rate to reduce the amount of data and ensure the stability of transmission.

[0041] When the drone 200 performs a flight monitoring mission, in order to ensure the real-time nature of the video data and adapt to the long-distance narrowband transmission conditions, the video data is transmitted in a low bit rate mode. This mode reduces the amount of data by reducing the bit rate of the video, thereby adapting to the low data rate characteristics of narrowband transmission and ensuring that the monitoring data can be transmitted in real time.

[0042] When the drone 200 completes the monitoring task and returns to the drone parking platform, the system automatically switches to broadband data transmission mode, or directly transmits data through the built-in connection line. At this time, the drone 200 transmits high-definition video data to the monitoring camera 100 or the server 400, and overwrites the previous compressed video data, and also uploads the high-definition data to the server 400. In this way, the user can view a clearer monitoring picture when needed, while retaining the real-time and continuity of the monitoring process.

[0043] In this embodiment, the user remotely connects to the surveillance camera 100 through a mobile phone or computer to view the surveillance images in real time. When the surveillance range needs to be expanded, the user can remotely control the drone 200 to take off, and the drone 200 will transmit the real-time surveillance images back. The user can view the images of the surveillance camera 100 and the drone 200 at the same time on the same terminal device.

[0044] In addition to remote control, the drone 200 can also have certain autonomous flight capabilities, such as automatic obstacle avoidance, fixed-point hovering, automatic return, etc., and fixed-point trajectory cruising to improve monitoring efficiency and safety. These functions are usually implemented through sensors (such as GPS, gyroscopes, visual sensors, etc.) and flight control systems on the drone 200; they can also be implemented through the preset of the terminal device 500; they can also be implemented through the intelligent recognition algorithm of the monitoring camera 100 and the triggering of the detector.

[0045] The above embodiments 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 the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention.
