Description

Technical Field

[0001] This application relates to the field of surveillance technology, and in particular to a surveillance sphere. Background Technology

[0002] In construction site operations, monitoring is necessary to ensure worker safety. For example, fixed surveillance cameras can be installed. However, construction sites are typically large, and suitable locations for multiple fixed cameras are often lacking. One related technology uses a non-fixed surveillance PTZ camera, which can be moved flexibly to accurately monitor the workers' work area. However, this type of PTZ camera is usually similar in form to fixed surveillance cameras, and in the complex, open environment of a construction site, it is easily damaged by rain, impacts, etc., compromising equipment safety. Utility Model Content

[0003] The purpose of this application is to at least solve one of the technical problems existing in the prior art, and to provide a control ball that aims to ensure the equipment safety of the control ball and improve its reliability.

[0004] This application provides a control ball, including a base. One side of the base is provided with a metal shell, a battery module and a monitoring camera module, and the other side of the base is provided with a support leg and an antenna module. The height of the antenna module is less than the height of the support leg.

[0005] A status indicator module is provided on the metal casing, and a control motherboard is provided inside the metal casing. The control motherboard is connected to the battery module, the status indicator module, and the monitoring camera module. The control motherboard includes a first communication module, which is connected to the antenna module. The control motherboard is used to receive images captured by the monitoring camera module, transmit the images captured by the monitoring camera module through the first communication module and the antenna module, and indicate the working status of the surveillance ball through the status indicator module. The first communication module includes a cellular communication module.

[0006] According to the technical solution of this application embodiment, it has at least the following beneficial effects: When the surveillance ball is installed on an outdoor construction site, due to the large amount of sand and gravel on the site, the flying sand and gravel can easily hit the surveillance ball and cause damage. Furthermore, due to the large amount of equipment, building materials, and other materials on the site, the surveillance ball is also easily damaged when machines or workers are working. Therefore, the outer shell of the surveillance ball is made of metal, which can greatly enhance its mechanical strength and ensure its equipment safety. In addition, one side of the base is provided with a metal shell and a monitoring camera module, while the other side of the base is provided with a support leg and an antenna module. That is, the antenna module is located at the bottom of the surveillance ball, which can effectively prevent the antenna module from being exposed to rain. The antenna module is designed to withstand damage such as rain, and its height is less than that of the support legs. The open space created by the higher support legs prevents the antenna module from being affected by rain, even though it is located at the bottom of the control sphere. This enhances the reliability of the control sphere by improving the waterproof performance of the antenna module, without affecting its normal operation. In addition, the control sphere includes a battery module, meaning it has a built-in high-capacity battery power supply and does not need to be plugged in, thus enhancing its usability. Furthermore, the first communication module can be a cellular communication module, allowing the control sphere to have its own data SIM card, eliminating the need for Wi-Fi internet access and further enhancing its usability.

[0029] The present application will be further described below with reference to the accompanying drawings.

[0030] like Figure 1 As shown, Figure 1 This is a schematic block diagram of the structure of a deployment ball provided in one embodiment of this application; the deployment ball includes a base 100, one side of the base 100 is provided with a metal shell 200, a battery module 800 and a monitoring camera module 300, and the other side of the base 100 is provided with a support leg 400 and an antenna module 500, the height of the antenna module 500 is less than the height of the support leg 400;

[0031] A status indicator module is provided on the metal casing 200, and a control motherboard 700 is provided inside the metal casing 200. The control motherboard 700 is connected to the battery module 800, the status indicator module, and the monitoring camera module 300. The control motherboard 700 includes a first communication module, which is connected to the antenna module 500. The control motherboard 700 is used to receive images captured by the monitoring camera module 300, and to transmit the images captured by the monitoring camera module 300 through the first communication module and the antenna module 500, as well as to indicate the working status of the surveillance ball through the status indicator module. The first communication module includes a cellular communication module.

[0032] Understandably, a surveillance PTZ camera is a portable intelligent security device that integrates multiple functions such as video surveillance, wireless transmission, and environmental monitoring. In construction site scenarios, surveillance PTZ cameras can solve problems such as difficult cabling, fixed viewing angles, and delayed response in traditional surveillance systems. For example, in large-scale infrastructure projects, surveillance PTZ cameras can be flexibly deployed in high-risk areas such as tower cranes, material storage areas, and deep foundation pits, capturing operational footage through 360° rotation.

[0033] For example, the surveillance ball includes a base 100. One side of the base 100 is provided with a metal shell 200, a battery module 800, and a monitoring camera module 300. The other side of the base 100 is provided with a support leg 400 and an antenna module 500. The material selection of the surveillance ball base 100 takes into account structural strength, environmental adaptability, and electromagnetic compatibility. It can be made of aluminum alloy die-casting process, which has the characteristics of light weight and corrosion resistance; or it can be made of glass fiber reinforced nylon material, which meets the explosion-proof requirements and avoids the static electricity risk that may be caused by metal materials. In one embodiment, the material selection of the metal shell 200 and the base 100 needs to be comprehensively selected based on indicators such as impact resistance, temperature tolerance range, and dielectric constant.

[0034] For example, the base 100 can employ differentiated assembly schemes on both sides. The side containing the metal casing 200 can be secured with countersunk screws and sealing rings, with conductive foam added at the seams to ensure EMC compliance, or it can be secured using a snap-fit ​​mechanism. The antenna module 500 side can be embedded, for example, by pre-embedding threaded inserts during the injection molding of the base 100, and then using an RF coaxial connector for modular quick-release, facilitating the replacement of antennas with different gains to adapt to varying signal strength environments. The antenna base can be equipped with a three-tiered waterproof structure: an outermost silicone sealing ring to prevent rainwater penetration, a middle PTFE breathable membrane to balance air pressure, and an inner nano-hydrophobic coating to prevent condensation from corroding the circuitry.

[0035] For example, the surveillance camera module 300 is not completely housed within the metal casing 200. This is because the camera 310 needs to be exposed for shooting, and heat dissipation is required through air convection on the exposed part. Furthermore, the co-location interference between the antenna module 500 and the surveillance camera module 300 requires that the distance between them be within a certain range. Therefore, the surveillance camera module 300 can adopt a semi-embedded layout, placing the core components of the camera (CMOS sensor, processing chip) within the metal casing 200, while the lens group, infrared fill light, and other extended components are exposed and can be fixed with an aluminum alloy ring bracket.

[0036] For example, the other side of the base 100 is provided with a support leg 400 and an antenna module 500, the height of which is less than that of the support leg 400. It is understandable that, from a physical protection perspective, the support leg 400 can serve as a buffer zone for the antenna module 500. Because long materials such as steel pipes and scaffolding are commonly handled in construction environments, the support leg 400 will absorb the impact first in the event of an accidental collision. Therefore, the top of the support leg 400 can be made of an elastic material, and the installation position of the antenna module 500 is within the elastic deformation protection range of the support leg 400. This way, even if the control ball falls from a height, it can protect the antenna module 500. Simultaneously, the air convection channel formed by the height difference can accelerate the airflow. The antenna base provides heat dissipation. Furthermore, the open space created by the higher support legs 400 allows the angle between the support legs 400 and the ground to absorb some of the reflected waves when electromagnetic waves radiate at a certain elevation angle. This makes the radiation pattern of the antenna module 500 closer to a free-space mode, preventing the antenna module 500 from being affected by rain or other factors simply because it is located at the bottom of the control sphere. Thus, the reliability of the control sphere is further enhanced by improving the waterproof performance of the antenna module 500, without affecting its normal operation.

[0037] For example, the control motherboard 700, as the core processing unit of the surveillance PTZ camera, can integrate multiple components such as a main control processor, a first communication module, a power management unit, a storage unit, and an interface controller. The main control processor can adopt a multi-core ARM architecture and is responsible for overall system scheduling and basic image processing. The first communication module includes a cellular communication module, therefore, the first communication module includes a 4G / 5G baseband chip and a 4G / 5G data card for data transmission. The power management unit supports wide voltage input and dynamic power consumption adjustment to adapt to the unstable power supply environment of the construction site. The storage unit is used to cache video streams and algorithm models. The interface controller integrates multiple industrial-grade standard interfaces, such as MIPI-CSI for camera 310 connection, PCIe for high-speed data transmission, and GPIO for indication and triggering.

[0038] For example, the first communication module is connected to the antenna module 500. The first communication module includes a 4G / 5G baseband chip and a 4G / 5G data card. The antenna module 500 may include a corresponding antenna for cellular communication. In this way, the control motherboard 700 can send images captured by the monitoring camera module 300 through the first communication module and the antenna module 500.

[0039] For example, in the control motherboard 700, the raw image data is input from the monitoring camera module 300 via the MIPI interface, and then denoised and HDR processed by the ISP (Image Signal Processor). At the same time, the main control processor encodes the video stream into H.265 format and transmits it to the communication module via the PCIe bus. Finally, it is sliced ​​and transmitted to the cloud or user terminal by the 4G / 5G baseband chip or Wi-Fi module.

[0040] For example, the connection between the control motherboard 700 and the status indicator module can be achieved by opto-isolation and relay driving. When the working state of the control motherboard 700 changes, the GPIO output level is used to drive the relay after opto-isolation, ultimately controlling the power supply circuit of the status indicator module.

[0041] For example, the surveillance ball also includes a battery module 800, which is connected to the control motherboard 700. In other words, the surveillance ball provided in this application embodiment can be used without being plugged in, but is powered by a built-in battery, which greatly improves the flexibility of the surveillance ball.

[0042] In some embodiments of the present application, the base 100 is provided with a support frame 210 on one side of the metal housing 200. The support frame 210 is disposed inside the metal housing 200, and the control motherboard 700 is disposed inside the support frame 210.

[0043] refer to Figure 2 , Figure 2This is a schematic diagram of the internal structure of the control ball according to another embodiment of this application; the base 100 has a support frame 210 on one side of the metal shell 200, and the support frame 210 is disposed inside the metal shell 200. The control motherboard 700 is disposed inside the support frame 210. In this way, the metal shell 200 serves as the first level of protection and can directly withstand external impacts such as flying stones and falling tools commonly seen on construction sites; the support frame 210 serves as the second level of buffer and can be made of magnesium alloy or carbon fiber composite material to disperse the impact force throughout the frame, thereby reducing the acceleration transmitted to the control motherboard 700; furthermore, the silicone shock-absorbing pad between the control motherboard 700 and the support frame 210 can serve as the third level of protection, and its damping coefficient can effectively absorb high-frequency vibration energy, avoiding fatigue fracture of PCB solder joints. In addition, the metal shell 200 serves as the main heat dissipation body and can quickly dissipate the heat generated by the control motherboard 700 through conduction; the support frame 210 also quickly dissipates the heat generated by the control motherboard 700 through conduction. In addition, the metal casing 200 acts as a Faraday cage, which can attenuate external electromagnetic interference. The support frame 210 can form an internal shielding layer through surface nickel plating, forming a dual-cavity structure with the casing, which limits the radiated noise of the control motherboard 700.

[0044] In some embodiments of the present application, the control ball is provided, and the metal shell 200 is a three-section integrally formed metal shell including a first shell 230, a second shell 240 and a third shell 250 connected in sequence. The first shell 230 and the third shell 250 are vertically arranged, and the second shell 240 is inclined relative to the first shell 230 and the third shell 250.

[0045] refer to Figure 3 , Figure 3 This is a schematic diagram of the structure of a control ball provided in another embodiment of this application; the metal shell 200 is a one-piece molded metal shell, and the metal shell 200 has a three-section design, including a first shell 230, a second shell 240, and a third shell 250 connected in sequence. The first shell 230 and the third shell 250 are vertically arranged, while the second shell 240 is inclined relative to the first shell 230 and the third shell 250. This inclined design of the second shell 240 creates an active water-guiding mechanism, making its waterproof performance far superior to that of traditional vertical shells. When rainwater impacts the shell, rapid drainage can be achieved through the inclined surface of the second shell 240.

[0046] For example, the connection between the third housing 250 and the second housing 240 can also adopt a concave guide channel design, so that all rainwater flowing down the inclined surface is forced into the channel and discharged through the drainage holes on both sides.

[0047] For example, the three-segment asymmetric structure can significantly improve overall rigidity through stress redistribution. When the shell is subjected to lateral impact, the inclined surface of the second shell 240 decomposes the horizontal impact force into axial pressure and tangential force, thereby improving the overall bending stiffness. The inclined angle of the second shell 240 makes it a preferential zone for plastic deformation, protecting the internal control motherboard 700 under impact. Furthermore, the discontinuous curvature design changes the natural frequency of the structure, which can shift and enhance the resonance peak. Combined with the damping material of the internal support frame 210, this reduces the failure rate of the control ball under vibration.

[0048] In some embodiments of this application, the surveillance camera module 300 includes a camera 310 and a rotating pan-tilt unit 320 connected to each other. The rotating pan-tilt unit 320 is used to drive the camera 310 to rotate and shoot. The rotating pan-tilt unit 320 is connected to the control motherboard 700.

[0049] In this embodiment, the monitoring camera module 300 includes a camera 310 and a rotating pan-tilt unit 320 connected to each other. The camera 310 can be a 400W pixel camera 310, which can shoot 2K resolution high-definition video, supports H.265 video encoding, dual bitstream, etc.

[0050] For example, the gimbal 320 is used to drive the camera 310 to rotate and shoot. The gimbal 320 is connected to the control motherboard 700, which can control the rotation of the gimbal 320, thereby causing the camera 310 to rotate and shoot. In addition, control commands can be sent through the communication module in the control motherboard 700 to remotely control the horizontal and vertical movement of the camera 310.

[0051] In some embodiments of the deployment ball provided in this application, the first communication module is connected to the antenna module 500 to realize the first communication connection with the management platform terminal. The control motherboard 700 is also used to transmit images captured by the monitoring camera module 300 to the management platform terminal in real time through the first communication connection.

[0052] refer to Figure 4 and Figure 5 , Figure 4 This is a circuit diagram of a control motherboard 700 provided in another embodiment of this application. Figure 5This is a circuit simulation diagram of a control motherboard 700 provided in another embodiment of this application. In this embodiment, the control motherboard 700 includes a first communication module. The control motherboard 700 includes multiple power interfaces. The control motherboard 700 is used for power distribution and signal processing of the control ball. That is, the control motherboard 700 can provide reasonable power supply to modules with different operating voltages, process the working status information through the MCU, output it to the status indication module for indication, and transmit the images captured by the monitoring camera module 300 to the management platform terminal in real time through the first communication connection, and output the working status information to the management platform terminal through the first communication module.

[0053] In one embodiment, the inputs of the control motherboard 700 include a power input (DC 10.8~12.6V), and the outputs of the control motherboard 700 include a power supply for the camera 310 (output voltage DC 12V), a power supply for the status indicator module (output voltage DC 12V), and a power supply for the first communication module (output voltage DC 9~24V).

[0054] In some embodiments of the deployment ball provided in this application, the control motherboard 700 includes a second communication module. The control motherboard 700 establishes a second communication connection with the user terminal through the second communication module to send deployment ball status prompts to the user terminal.

[0055] Understandably, the control motherboard 700 can transmit images captured by the monitoring camera module 300 to the management platform terminal in real time through the first communication connection. That is, remote monitoring and remote playback can be realized through the first communication connection. In order to see the prompts more intuitively, a second communication module can be added. The control motherboard 700 establishes a second communication connection with the user terminal through the second communication module. That is, the control motherboard 700 establishes a second communication connection with the workers on the construction site through the second communication module. In this way, when the working status of the surveillance camera changes, such as when the power is low, it can be directly sent to the user terminal of the workers on site through the second communication connection.

[0056] In some embodiments of the present application, the status indication module includes an indicator horn and at least one indicator light 220, which are disposed on the surface of the metal housing 200.

[0057] refer to Figure 3 In this embodiment, the status indication module includes multiple indicator lights 220, and the indicator speaker and multiple indicator lights 220 are all disposed on the surface of the metal casing 200. Thus, when the status indication module is triggered to indicate, the indicator speaker can be triggered to broadcast the corresponding indication content, and the multiple indicator lights 220 can be controlled to flash, thereby increasing the reminder through the combination of sound and light.

[0058] In some embodiments of the control ball provided in this application, the battery module 800 is disposed within the support frame 210.

[0059] In this embodiment, the battery module 800 is disposed inside the support frame 210. The metal housing 200 and the support frame 210 can simultaneously protect the control motherboard 700 and the battery module 800, further improving the reliability of the control ball.

[0060] In some embodiments of this application, the control ball also includes a power meter 900, which is disposed on the surface of the metal casing 200 and connected to the battery module 800.

[0061] In this embodiment, the control ball also includes a power meter 900, which is disposed on the surface of the metal casing 200 and is directly connected to the battery module 800, thereby directly detecting the power level of the battery module 800 and displaying the current power level through the power meter 900.

[0062] In some embodiments of the present application, the base 100 is provided with a quick-release plate on one side of the metal housing 200, which is used to install an external tripod.

[0063] In this embodiment, the control ball has two different installation methods, including the support leg 400 provided at the bottom of the base 100, which can be placed and used immediately, and the external tripod set by the quick-release plate.

[0064] Understandably, the tripod's support enhances the stability and safety of the surveillance camera, as construction sites often have uneven ground or soft soil. The tripod's three-point support structure can effectively adapt to various complex terrains, preventing the equipment from tilting or tipping over due to uneven ground. Furthermore, its adjustable height allows for flexible adjustment of the monitoring angle, covering blind spots that are difficult for traditional fixed cameras to reach.

[0065] In one embodiment, before construction begins, workers select a suitable tripod and quickly install the surveillance camera in key areas of the construction site, such as material storage areas, tower crane operating areas, or near deep foundation pits, using a quick-release plate. The tripod height is then adjusted to approximately 1.5 meters to ensure the monitoring view covers the main work area, and all fixing screws are tightened to prevent loosening. After the surveillance camera is powered on, the control motherboard 700 inside the metal casing 200 automatically starts, initializes the system, the first communication module searches for signals and connects to the project management platform, and the second communication module connects to the workers' mobile phones. Workers view the real-time footage via a mobile app. After confirming there are no blind spots in the monitoring range, the surveillance camera officially begins operation.

[0066] During construction, the surveillance sphere operates 24 / 7, while the monitoring camera module 300 captures high-definition video streams and saves the images to a local SD card, transmitting them in real-time to the management platform terminal via the first communication module. In case of heavy rain, the tilted design of the metal casing 200 effectively diverts rainwater, preventing water accumulation from affecting equipment operation. When the monitoring points need to be adjusted at different stages of construction, the shock-resistant design of the control motherboard 700 protects the core components from vibration damage during relocation.

[0067] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
