For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.
[0030] like Figures 1 to 6 As shown, an embodiment of the utility model provides an outdoor camera 100, including a casing 1, a lens 2 is provided on the surface of the casing 1, a heating component, a protective plate 3 and a camera 4 are provided inside the casing 1, and the camera 4 faces the lens 2; the protective plate 3 is arranged between the camera 4 and the lens 2, and the protective plate 3, the casing 1 and the lens 2 form a receiving cavity, the heating component is arranged in the receiving cavity, the heating component includes a heating wire 5 and a heat conducting plate 6, the heating wire 5 is connected to the heat conducting plate 6, the heat conducting plate 6 faces the lens 2, the protective plate 3 is provided with a first through hole 7, and the heat conducting plate 6 is provided with a second through hole 8, and the first through hole 7 and the second through hole 8 both correspond to the camera 4.
[0031] Based on the above technical solution, the camera 4 faces the first through hole 7 on the protective plate 3 and the second through hole 8 on the heat conducting plate 6. External light enters the camera 4 from the lens 2 through the first through hole 7 and the second through hole 8. The camera 4 serves as a camera subject for capturing and transmitting images.
[0032] In this embodiment, a heating component is provided inside the camera, which is the key to preventing ice formation. The heating component includes a heating wire 5 and a heat conducting plate 6, and the heating wire 5 is connected to the heat conducting plate 6. When the heating wire 5 is energized, heat is generated. Since the heat conducting plate 6 faces the lens 2, the heat generated by the heating wire 5 can be evenly radiated and transferred to the surface of the lens 2 through the heat conducting plate 6. The protective plate 3 is used to protect the camera 4 and isolate the heat radiation of the heating wire 5. The accommodating cavity enclosed by the protective plate 3, the housing 1 and the lens 2 provides an installation space for the heating component. The heat generated by the heating component accumulates in the accommodating cavity, forming a relatively closed constant temperature area, which effectively prevents the lens 2 from freezing. Compared with the method of using an external scraper to prevent fogging and deicing, the outdoor camera 100 of this embodiment generates heat through a built-in heating component and evenly transfers the heat to the lens 2 to prevent the lens 2 from freezing, ensuring that the outdoor camera 100 can work normally even in a low temperature environment, thereby improving reliability and stability.
[0033] In practical applications, either only one camera 4 or multiple cameras 4 may be provided, and this embodiment does not impose any specific limitation.
[0034] As an implementation method, Figure 2 and Figure 3 As shown, a heat-insulating cotton board 9 is also provided inside the casing 1 , and the heat-insulating cotton board 9 is filled between the protective plate 3 and the heat-conducting plate 6 . The heat-insulating cotton board 9 is provided with a third through hole 10 , and the third through hole 10 corresponds to the camera 4 .
[0035] Specifically, the main function of the heat preservation cotton board 9 is to reduce heat loss and improve the heat preservation effect. In an outdoor low-temperature environment, the heat generated by the heating component is easily dissipated to the outside through the gaps in the housing 1 or the material itself, causing the temperature of the surface of the lens 2 to drop, thereby affecting the deicing effect. In this embodiment, the heat preservation cotton board 9 is filled between the protective plate 3 and the heat conducting plate 6 to reduce heat loss, form a relatively stable temperature field in the accommodating cavity, and maintain the temperature of the surface of the lens 2 in a constant range, thereby preventing ice from forming.
[0036] As an implementation method, Figure 2 and Figure 3 As shown, the heating wire 5 is attached to the side of the heat conducting plate 6 close to the protection plate 3 , and the heating wire 5 surrounds the second through hole 8 .
[0037] Specifically, the heating wire 5 is directly attached to the side of the heat conducting plate 6 to ensure that the heat can be quickly transferred to the heat conducting plate 6. The heat conducting plate 6 is a heat transfer medium, and its good thermal conductivity can evenly distribute the heat to the entire plate surface.
[0038] In this embodiment, on the heat conducting plate 6, except for the position of the second through hole 8 (to avoid interference with the camera 4), the heating wire 5 can be attached to other positions. The heating wire 5 is arranged in a winding manner at various locations on the plate surface to increase the contact area between the heating wire 5 and the heat conducting plate 6 as much as possible. This can ensure that the heat is evenly distributed on the heat conducting plate 6 and can also reduce heat loss and waste.
[0039] As an implementation method, Figure 3 As shown, a mounting groove 11 is provided on the side of the heat conducting plate 6 close to the protective plate 3 , and the heating wire 5 is embedded in the mounting groove 11 .
[0040] Specifically, by setting the mounting groove 11 on the heat conducting plate 6 and embedding the heating wire 5 therein, it can be ensured that the contact between the heating wire 5 and the heat conducting plate 6 is closer, so that heat can be transferred from the heating wire 5 to the heat conducting plate 6 more quickly and effectively, thereby improving the heat transfer efficiency.
[0041] In this embodiment, since the heating wire 5 is embedded in the mounting groove 11, its layout can be more regular and orderly, and the heat distribution can be further optimized by adjusting the shape, size and position of the mounting groove 11. In addition, embedding the heating wire 5 in the mounting groove 11 can improve the stability of the heating component and prevent the heating wire 5 from shifting or falling off during use. The design of the mounting groove 11 makes the installation of the heating wire 5 easier and faster.
[0042] As an implementation method, Figure 2 and Figure 4 and Figure 5 As shown, a plurality of cameras 4 are provided inside the housing 1, and the plurality of cameras 4 are arranged in a horizontal and vertical array; the mounting groove 11 includes a plurality of first groove bodies 111 and a plurality of second groove bodies 112, and the plurality of first groove bodies 111 are arranged at intervals along the horizontal direction, and the second groove body 112 is arranged between two adjacent first groove bodies 111 and connects two adjacent first groove bodies 111, and the second groove body 112 and the two adjacent first groove bodies 111 form a U-shaped structure, and the openings of the two adjacent U-shaped structures are arranged back to back.
[0043] Specifically, the camera of this embodiment is a panoramic camera, and multiple cameras 4 are arranged in horizontal and vertical arrays, and each camera 4 corresponds one by one to the first through hole 7, the second through hole 8 and the third through hole 10. Such a layout can expand the camera's shooting range, realize multi-angle and multi-directional monitoring, and achieve a wider field of view coverage.
[0044] Among them, the first groove body 111 and the second groove body 112 can be integrally formed, and the second groove body 112 and the two adjacent first groove bodies 111 form a U-shaped structure, or in other words, the first groove body 111 and the second groove body 112 form an S-shaped groove structure surrounding the second through hole 8, and the heating wire 5 is embedded in the groove body, so that the contact area between the heating wire 5 and the heat conducting plate 6 can be increased to the maximum extent.
[0045] As an implementation method, Figure 2 As shown, at least two temperature control probes 12 are disposed inside the housing 1. The at least two temperature control probes 12 are arranged at intervals, and the temperature control probes 12 are used to detect the temperature inside the accommodating cavity.
[0046] Specifically, by setting at least two temperature control probes 12 at intervals, the temperature data of different positions in the accommodating cavity can be obtained, which helps to more accurately obtain the overall temperature distribution in the accommodating cavity, rather than just the temperature of a single position. The working state of the heating component (or heating wire 5) is accurately adjusted according to the temperature data to achieve a preset target temperature or temperature range.
[0047] For example, two temperature control probes 12 are arranged in the accommodating cavity. Even if one of the temperature control probes 12 fails, the other temperature control probe 12 can still continue to work and provide temperature monitoring data. This redundant design ensures that the camera will not fail completely due to the failure of a single component, thereby improving the reliability of the camera.
[0048] As an implementation method, Figure 6 As shown, a control mainboard 13 is disposed inside the housing 1, and the control mainboard 13 is used to control the heating wire 5 according to the temperature in the accommodating cavity.
[0049] Specifically, the control mainboard 13 can automatically adjust the working state of the heating wire 5 according to the real-time temperature data in the accommodating chamber, so that the temperature of the surface of the lens 2 is maintained in a constant range, thereby preventing ice from forming. When the temperature in the accommodating chamber reaches a preset range, the control mainboard 13 can automatically reduce the heating power of the heating wire 5 or turn off the heating wire 5.
[0050] For example, when the temperature control probe 12 detects that the temperature in the constant temperature zone reaches T0 = 0 degrees freezing point, a signal is transmitted to the control mainboard 13 to start the heating wire 5 to heat, and the temperature in the accommodating cavity is controlled at Th = 5 degrees through the radiation effect of the automatic heating wire 5 and the heat conducting plate 6. When the control mainboard 13 receives the low temperature signal from the temperature control probe 12, the heating wire 5 is immediately started for heating, and the constant temperature function is started according to the signal of the temperature control probe 12.
[0051] As an implementation method, Figure 1 and Figure 6As shown, the outdoor camera 100 further includes a protective cover 14 , which is connected to the top of the housing 1 .
[0052] Specifically, the protective cover 14 can shield the top of the housing 1, prevent snow, rain, frost and other moisture from directly contacting the top of the housing 1, reduce the risk of ice on the top of the housing 1, ensure the camera continues to operate stably, and will not be affected by ice accumulation. In addition, the protective cover 14 can also prevent dust, dirt and other debris from accumulating on the top of the housing 1.
[0053] As an implementation method, Figure 2 and Figure 3 As shown, the housing 1 includes a first shell 15 and a second shell 16 , the first shell 15 and the second shell 16 are detachably connected, and the lens 2 is disposed on the surface of the first shell 15 .
[0054] Specifically, the detachable connection between the first housing 15 and the second housing 16 makes it easier to repair and replace components of the outdoor camera 100. When the temperature control probe 12 or the control mainboard 13 fails, the first housing 15 or the second housing 16 can be removed to quickly replace or repair the failed component, thereby improving maintenance efficiency.
[0055] As an implementation method, Figure 1 and Figure 6 As shown, the outdoor camera 100 also includes a support 17, which is rotatably connected to the bottom of the housing 1, so that the outdoor camera 100 can be rotated and adjusted at multiple angles. According to actual needs, the shooting angle of the camera is automatically adjusted to meet the monitoring needs in different scenes. For example, the camera angle can be adjusted to cover a wider area, or to focus on monitoring a specific area.
[0056] In a second aspect, an embodiment of the utility model provides a monitoring system, including an outdoor camera 100 .
[0057] Specifically, the monitoring system supports remote monitoring and control functions, and can remotely view monitoring images, adjust camera angles, set monitoring parameters, etc. through terminal devices such as mobile phones and computers. In this embodiment, the outdoor camera 100 can collect video and audio data of the monitoring area in real time, has anti-icing properties, and can work normally under low temperature weather conditions.
