[0029] For the camera proposed in this utility model, please refer to [link / reference]. Figure 1 ,include:
[0030] Camera unit 10, the camera unit 10 includes a camera module 11 and a first housing 12, the camera module 11 being fixedly mounted on the first housing 12; and
[0031] The sensing body 20 includes a sensing module and a second housing 23. The sensing module includes two infrared sensors 21 and two Fresnel lenses 22. The two infrared sensors 21 are fixed on the same side in the second housing 23. The two Fresnel lenses 22 are disposed on the surface of the second housing 23. Each Fresnel lens 22 covers one infrared sensor 21.
[0032] The first housing 12 is connected to the second housing 23. The electronic control system is located in the second housing 23 and the first housing 12. The camera module 11 and the sensor body 20 are both electrically connected to the electronic control system.
[0033] In the technical solution of this utility model, the camera can be applied outdoors, such as in a courtyard. The camera integrates an infrared sensor 21 and a camera module 11, realizing multi-functional monitoring. Among them, the infrared sensor 21 can effectively improve the image quality of the camera at night and enhance the real-time response and prevention capabilities required for monitoring.
[0034] The camera unit 10 is mainly used to realize the camera function, and the sensing body 20 is mainly used to realize the infrared sensing function. An electronic control system for controlling the operation of the camera is located in the first housing 12 and the second housing 23. The electronic control system is electrically connected to an external circuit and can achieve communication with smart devices such as mobile phones and computers. Users can issue control commands through corresponding control programs to achieve simultaneous or time-sharing operation of the camera and infrared sensing, thereby improving the practicality of the camera. Specifically, the first housing 12 encloses a first receiving cavity, in which the camera module 11 and the electronic control system are fixed. The camera module 11 includes a lens, an image sensor, a voice coil motor, and other structures. Light focused by the lens is refracted and forms an inverted real image on the image sensor. The light signal received by the image sensor is converted into an electrical signal, which is then sent to an image processing chip (such as a DSP or ISP) for further processing, including amplification, filtering, and color correction, ultimately forming a digital signal and outputting it in a standard format (such as RGB, YUV, etc.) for subsequent display or... For storage and use, the entire camera module 11 is fixed in the first housing 12, achieving functions such as fixation and waterproofing. The first housing 12 is located above the second housing 23, which encloses to form a second receiving cavity. The sensing module is fixed in the second receiving cavity. The sensing module includes two infrared sensors 21 and two Fresnel lenses 22. Both infrared sensors 21 are fixed in the second receiving cavity. For example, a limiting plate can be fixed in the second receiving cavity, and the infrared sensors 21 can be glued to the limiting plate, or the limiting plate can have a limiting groove, and the infrared sensors 21 can be glued to the limiting groove. There is no limitation here. In order to improve the focusing of the infrared sensors 21, two Fresnel lenses 22 are fixed on the outer surface of the second housing 23. The Fresnel lenses 22 can be fixed on the outer surface of the second housing 23 by snap-fit. Then, sealant is used to seal the surface to prevent water seepage and dust ingress when the camera is used outdoors. It is understood that the infrared sensors 21 can be active infrared sensors 21 or passive infrared sensors 21. There is no limitation here.
[0035] Further, please refer to Figure 2 To achieve wide-angle sensing and recognition by the sensing module, the end face of the second housing 23 facing the first housing 12 is defined as the reference surface. The distance between the two infrared sensors 21 and the reference surface is set at equal intervals. In this way, the two infrared sensors 21 are set at the same height on the camera, which can make the detection range of the sensing module wider and cover more spatial areas. At the same time, by using the Fresnel lens 22, the detection area of the infrared sensor 21 can be divided into several bright areas and dark areas, so that moving objects entering the detection area can generate changing pyroelectric infrared signals on the sensor in the form of temperature changes, thereby realizing wide-angle sensing and recognition.
[0036] In one embodiment of this utility model, please refer to Figure 2 The second housing 23 is provided with a sealing element 24, which has two sealing grooves 24a. Each infrared sensor 21 is located at the bottom of a sealing groove 24a, and each Fresnel lens 22 covers a sealing groove 24a. Specifically, with the central axis of the second housing 23 in the longitudinal direction as a reference line, the two sealing grooves 24a are equidistant from the reference line defined in the transverse direction, so that the two infrared sensors 21 are symmetrically distributed on the second housing 23. This helps to achieve more uniform detection area coverage and improve the overall performance of the sensing module. At the same time, the Fresnel lens 22 can cover the opening of the sealing groove 24a, so that the infrared sensor 21 is in a sealed space, reducing the degree of interference of the infrared sensor 21 from external factors such as water vapor and dust in the air.
[0037] Further, please refer to Figure 2 To achieve 360-degree infrared sensing detection, the second housing 23 is equipped with a circumferential transmission mechanism 30. The circumferential transmission mechanism 30 includes a first rotary motor 31 and a transmission gear set 32. The transmission gear set 32 includes at least a meshing first gear and a second gear. The first rotary motor 31 is electrically connected to an electronic control system. The first gear is located on the output shaft of the first rotary motor 31. The first housing 12 is connected to the second gear to rotate circumferentially relative to the second housing 23. Specifically, the first rotary motor 31 is electrically connected to the electronic control system. When circumferential rotation of the infrared sensor 21 is required, the system controls the intelligent device to issue a circumferential rotation command. Under this command, the electronic control system drives the first rotary motor 31 to rotate. The first rotary motor 31 drives the first gear on its output shaft to rotate. In this process, the first gear and the second gear can mesh with any number of gears through the required transmission ratio. Alternatively, the first gear can directly mesh with the second gear, thereby driving the second gear to rotate. It can be understood that the first rotary motor 31 and the transmission gear set 32 can be set at any angle, as long as the second gear can rotate circumferentially. The first housing 12 has an insertion section that inserts into the second housing 23. The insertion section is fixedly connected to the inner diameter of the second gear, thereby driving the first housing 12 to rotate circumferentially relative to the second housing 23, realizing the 360-degree rotation of the infrared sensor 21 in the circumferential direction.
[0038] In one embodiment of this utility model, please refer to Figure 2The first housing 12 includes a first rotating part 121 and a second rotating part 122. The first rotating part 121 is connected to a second gear. The second rotating part 122 is fixedly equipped with a second rotary motor 13 and a camera module 11. The second rotary motor 13 is electrically connected to an electronic control system. The output shaft of the second rotary motor 13 is rotatably inserted into the first rotating part 121, so that the second rotating part 122 tilts relative to the first rotating part 121. The camera module 11 is fixedly installed in the second rotating part 122. Specifically, the first rotating part 121 has an insertion section and two connecting arms. The insertion section is inserted into the second housing 23 to connect to the second gear. The two connecting arms are arranged opposite each other to form a rotation space. The second rotating part 122 is located in the rotation space and connected to the two connecting arms. A second rotary motor 13 is fixed to one side of the rotating part 122 near a connecting arm. The output shaft of the second rotary motor 13 is rotatably inserted into the connecting arm. The side of the second rotating part 122 near the other connecting arm is connected to the connecting arm through a structure such as a rotating shaft. The second rotary motor 13 is placed horizontally so that the central axis of the output shaft is parallel to the horizontal line. When the second rotary motor 13 rotates, the first rotating part 121 can only rotate in the circumferential direction. The other directions are constrained by the second housing 23, so it cannot drive the first rotating part 121 to rotate. At this time, the first rotating part 121 gives the second rotary motor 13 a reaction force. Under this reaction force, the second rotating part 122 tilts relative to the first rotating part 121, so that the camera module 11 can realize multi-angle shooting.
[0039] Further, please refer to Figure 2 The first housing 12 is equipped with a searchlight 14, which is electrically connected to the electronic control system. The searchlight 14 and the infrared sensor 21 are arranged on the same side of the camera. Specifically, the searchlight 14 is fixedly mounted on the second rotating part 122. The searchlight 14 can generate a concentrated and bright beam of light for long-distance illumination, thereby improving the recognition capability of the infrared sensor 21 and the camera module 11 in the direction of the beam.
[0040] Further, please refer to Figure 2 The second housing 23 also includes two supplementary lighting modules. Each supplementary lighting module includes an infrared light supplementary lighting plate 41 and a visible light supplementary lighting plate 42. Both the infrared light supplementary lighting plate 41 and the visible light supplementary lighting plate 42 are provided with supplementary light sources. The infrared light supplementary lighting plate 41 and the visible light supplementary lighting plate 42 are arranged on the same side of the second housing 23 as the infrared sensor 21.
[0041] The outer surface of the second housing 23 is also provided with a total internal reflection lens 25 and an infrared lens 26. The total internal reflection lens 25 is aligned to cover the visible light supplement plate 42, and the infrared lens 26 is aligned to cover the infrared light supplement plate 41. In this way, the infrared light and visible light supplement emitted by the supplement light module can meet the needs of different monitoring scenarios. The color of the visible light is preferably white.
[0042] Further, please refer to Figure 2 To meet the multi-angle supplementary lighting requirements, the central axis of the second housing 23 along the longitudinal direction is defined as the reference line, and the two sets of supplementary lighting modules are arranged in a mirror-symmetrical manner along the reference line. In each supplementary lighting module, the infrared supplementary lighting plate 41 and the visible light supplementary lighting plate 42 are arranged towards the total internal reflection lens 25 along the same tilt direction relative to the reference line. The reference line of the infrared supplementary lighting plate 41 in each supplementary lighting module is located outside the visible light supplementary lighting plate 42. The two sets of supplementary lighting modules are arranged in the transverse direction as infrared supplementary lighting plate 41-visible light supplementary lighting plate 42-visible light supplementary lighting plate 42-infrared supplementary lighting plate 41. In this way, the light emitted by the tilted supplementary lighting plates passes through the total internal reflection lens 25, making the light more concentrated and projected onto the target area, thus improving the supplementary lighting effect. At the same time, the symmetrical layout of the two supplementary lighting modules helps to achieve uniform light distribution.
[0043] In one embodiment of this utility model, please refer to Figure 1 To enable the camera unit 10 and the sensor body 20 to rotate synchronously in the circumferential direction, the camera also includes a mounting bracket 50. The second housing 23 is rotatably connected to the mounting bracket 50. In one embodiment, the bottom of the second housing 23 is provided with multiple semi-circular holes, which are arranged in a circumferential matrix to form an arc of arbitrary length. On the side of the mounting bracket 50 facing the bottom of the second housing 23, multiple hemispherical protrusions are provided. The hemispherical protrusions are adapted to the semi-circular holes, and the multiple hemispherical protrusions are arranged in a circumferential matrix to form a complete circle. Thus, by applying a circumferential force to the sensor body 20, the sensor body 20 can be rotated, so that the camera unit 10 and the sensor body 20 can rotate synchronously in the circumferential direction. In another embodiment, a mechanism of motor and gear can also be used to enable the camera unit 10 and the sensor body 20 to rotate synchronously in the circumferential direction. It can be understood that by setting the spacing between every two semi-circular holes and hemispherical protrusions, the unit rotation angle of the sensor body 20 can be changed.
[0044] This utility model also proposes a monitoring system, which can be a mobile robot or an integrated device such as a drone. The monitoring system includes a camera and a mounting bracket 50, wherein the camera is connected to the mounting bracket 50. The specific structure of the camera is as described in the above embodiments. Since the monitoring system proposed by this utility model adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
[0045] The above are merely exemplary embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the technical concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
