Description

Technical Field

[0001] This utility model relates to the field of camera monitoring technology, specifically a camera monitoring device based on the Internet of Things. Background Technology

[0002] Through IoT technology, managers can monitor the real-time operating status of each wind turbine from a control center far from the wind farm. Whether in an office or via a mobile device, as long as there is an internet connection, they can access the monitoring system to observe the turbine's blade rotation, tower vibration, and other conditions. The IoT-based camera monitoring system provides real-time operating status information for the turbines, reducing the workload and time costs of manual inspections. Maintenance personnel can perform targeted inspections and repairs based on system alarm information, improving the efficiency of fault handling. For example, previously, a comprehensive inspection of all turbines was required periodically; now, the monitoring system can focus on turbines with alarms, significantly shortening the inspection cycle.

[0003] In existing technical solutions, video footage of the working environment of a wind farm can be collected by a monitoring camera during use. The footage can be processed by a microprocessor and transmitted to an external device via a wireless connector, solving the problem of not being able to monitor the working environment of the wind farm during use. However, since the damage to wind turbine equipment in a wind farm is mostly internal, the most obvious sign is a rapid rise in local heat. Since the monitoring camera can only collect video footage, it is too late when the external parts of the equipment are damaged by high temperatures. Utility Model Content

[0024] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0027] Example 1

[0028] Please see Figures 1 to 4 This is the first embodiment of the present invention, which provides an Internet of Things-based camera monitoring device, comprising:

[0029] The base 10 has two lifting cylinders 9 fixedly installed at the middle position of the upper end face of the base 10. The top of the lifting cylinder 9 is equipped with a movable screw seat 20. The top of the movable screw seat 20 is movably provided with a movable platform 6. The top of the movable platform 6 is rotatably equipped with a rotary table 5. A movable block 11 is provided on one side of the movable screw seat 20. The inside of the limiting plate 1 is provided with a limiting groove 12 that matches the movable block 11.

[0030] A fixed frame 3 is fixedly installed on the top of the rotating stage 5, and a fixing bolt 2 is installed on the top of the fixed frame 3. An infrared thermal imager 4 is fixedly installed inside the fixed frame 3.

[0031] Specifically, a limiting plate 1 is fixedly installed at the rear end of the base 10, and an IoT host 19 is set at the top of the base 10.

[0032] Furthermore, the data from the infrared thermal imager 4 can be transmitted to the IoT host 19, and then sent by the IoT host 19 to the station system to assist staff in monitoring the transformer station equipment.

[0033] Specifically, a servo motor 13 is fixedly installed on the upper surface of the moving platform 6, and a transmission shaft 14 is fixedly installed on the output end of the servo motor 13. The interior of the moving platform 6 is a hollow structure, and a drive wheel 15 and a driven wheel 17 are rotatably installed inside the moving platform 6. The driven wheel 17 and the drive wheel 15 are matched with each other, and the power output end of the driven wheel 17 is fixedly connected to the rotary table 5.

[0034] Furthermore, by controlling the rotation of the first servo motor 13, the drive wheel 15 can be rotated, which in turn drives the driven wheel 17 to rotate, thus rotating the rotary table 5 and automatically adjusting the monitoring range of the infrared thermal imager 4.

[0035] In use, the base 10 can be placed inside the transformer station, and the infrared thermal imager 4 (model: FLIR C5) can be installed inside the fixed frame 3. It can be connected to the IoT host 19 through the opening on the side of the fixed frame 3. Then, the infrared thermal imager 4 can be fixed with the fixing bolts 2. Next, the power supply of the lifting cylinder 9 can be turned on, and the lifting cylinder 9 can be started to drive the moving screw seat 20 to lift. The moving screw seat 20 is connected to the limit groove 12 through the moving block 11, thereby limiting the movement trajectory of the moving screw seat 20, thereby adjusting the height of the infrared thermal imager 4. Then, the power supply of the first servo motor 13 can be turned on to control the rotation of the first servo motor 13, so that it drives the drive wheel 15 to rotate, thereby driving the driven wheel 17 to rotate. This will drive the rotary table 5 to rotate, thereby driving the infrared thermal imager 4 to rotate, thereby increasing the monitoring range of the infrared thermal imager 4.

[0036] In summary, by pointing the infrared thermal imager 4 at the corresponding transformer station equipment, the heating status of the equipment inside the wind farm can be monitored in real time. The data from the infrared thermal imager 4 can be transmitted to the IoT host 19, and then sent by the IoT host 19 to the station system, thereby assisting the staff in monitoring the equipment in the wind farm.

[0037] Example 2

[0038] Please see Figure 1 , Figure 2 and Figure 3 This is the second embodiment of the present invention, which provides an improved design for a camera monitoring device based on the Internet of Things.

[0039] Specifically, a ball screw 8 is rotatably mounted inside the movable lead screw base 20. A second servo motor 18 is installed at the power input end of the ball screw 8. The second servo motor 18 is fixedly mounted on the top of the movable lead screw base 20. A lead screw nut seat 7 is sleeved on the outside of the ball screw 8, and the lead screw nut seat 7 is fixedly connected to the movable stage 6. Furthermore, by turning on the power to the second servo motor 18 and controlling its rotation, the second servo motor 18 drives the ball screw 8 to rotate, thereby moving the lead screw nut seat 7. This causes the movable stage 6 to move accordingly, thus automatically adjusting the monitoring range of the infrared thermal imager 4.

[0040] Specifically, a monitoring component 16 is provided on the back of the limiting plate 1. The monitoring component 16 includes a drive motor 161 fixedly installed on the back of the limiting plate 1. An assembly base 162 is fixedly installed on the output end of the drive motor 161. A monitoring camera 163 is fixedly installed on the upper surface of the assembly base 162.

[0041] Furthermore, the drive motor 161 can drive the mounting base 162 to rotate, and the mounting base 162 can drive the monitoring camera 163 to rotate, thus adjusting the monitoring range of the monitoring camera 163.

[0042] In use, the power supply to the second servo motor 18 is turned on, controlling the second servo motor 18 to rotate, which drives the ball screw 8 to rotate, thereby moving the screw nut seat 7. This causes the moving stage 6 to move accordingly, thus automatically adjusting the monitoring range of the infrared thermal imager 4. This allows the infrared thermal imager 4 to be automatically aimed at the equipment to be monitored. At the same time, the drive motor 161 is started, which drives the mounting base 162 to rotate. The mounting base 162 then drives the monitoring camera 163 to rotate, thus adjusting the monitoring range of the monitoring camera 163.

[0043] In summary, the combination of infrared thermal imager 4 and surveillance camera 163 can better improve the overall monitoring effect of the entire device.
