Description

Technical Field

[0001] This invention relates to the field of hunting camera technology, and in particular to a remotely activated hunting camera data retrieval device and system. Background Technology

[0002] A hunting camera is a specialized digital camera designed for outdoor activities. It typically features a visible light sensor, an infrared sensor, and a motion sensor. Normally in a low-power standby state, it automatically wakes up when the motion sensor detects movement, and then automatically takes photos and videos using the visible light or infrared sensor. Currently, the main applications of hunting cameras include monitoring wildlife and monitoring forest fires.

[0003] Hunting cameras used for monitoring wildlife or forest fires are typically deployed deep in forests. However, communication base stations are scarce deep in forests, and natural obstacles such as high mountains and trees easily block signal transmission, resulting in poor communication signals and making it difficult to upload the image data stored in the hunting cameras to the network. Current solutions to the problem of retrieving data from hunting cameras deep in the forest involve having staff manually enter the forest to replace the memory cards. This solution is not only time-consuming and labor-intensive, but also inefficient and poses safety risks. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide a remotely activated hunting camera data retrieval device and system.

[0005] This invention provides a remotely activated hunting camera data retrieval device, comprising: an external memory and a camera module mounted on the hunting camera, and a relay module mounted on a data relay device; the hunting camera transmits its captured image data to the external memory for storage; when the data relay device moves near the hunting camera, the relay module sends a pairing signal to the camera module, enabling the relay module and the camera module to establish a communication channel; wherein, the camera module is normally in a low-power mode, and switches to a wake-up mode after receiving the pairing signal from the relay module; the camera module controls the external memory to transmit the image data to the data relay device; the relay module instructs the data relay device to receive the image data, thereby completing the data retrieval.

[0006] This invention utilizes a data relay device to retrieve image data captured by hunting cameras deep in the forest. Compared to manual retrieval methods, it offers advantages such as cost savings and enhanced safety and efficiency. Addressing the limitation of existing hunting cameras' inability to directly access their internal memory, this invention designs a data retrieval device based on external memory. This eliminates the need to modify the existing structure of hunting cameras, solving the problem of remote data retrieval at a lower cost. Furthermore, this invention incorporates a mechanism for intelligent switching between low-power and wake-up modes for the camera-side module of the data transmission device, significantly reducing power consumption and adapting to applications where hunting cameras have limited battery life.

[0007] Furthermore, after the camera module switches to wake-up mode, it switches from wake-up mode to low-power mode if preset sleep conditions are met.

[0008] Furthermore, the preset sleep condition is: the communication channel between the camera module and the relay module disappears after a preset waiting time.

[0009] Furthermore, the camera module includes a main control unit and a high-throughput data transceiver unit; the camera module controls the external memory to transmit the image data to the data relay device, specifically including: the main control unit reads the image data in the external memory, preprocesses the image data, and then transmits it to the high-throughput data transceiver unit; the high-throughput data transceiver unit transmits the preprocessed image data in the form of radio waves, so that the data relay device receives the image data through the relay module.

[0010] Furthermore, the camera module also includes a secondary control unit and a low-throughput data transceiver unit. The camera module is normally in a low-power mode. Upon receiving a pairing signal from the relay module, it switches to a wake-up mode. Specifically, the secondary control unit normally cuts off the power supply to the main control unit and the high-throughput data transceiver unit, causing the low-throughput data transceiver unit to switch to WOR mode and itself to a low-power mode. At this time, the camera module is in a low-power mode. When the low-throughput data transceiver unit is in WOR mode, it detects the presence of a pairing signal at a preset scan cycle. If the low-throughput data transceiver unit detects a pairing signal, it switches from WOR mode to wake-up mode and forwards the pairing signal to the secondary control unit. After receiving the pairing signal, the secondary control unit switches from low-power mode to wake-up mode and restores the power supply to the main control unit and the high-throughput data transceiver unit, enabling them to operate. At this time, the camera module switches to wake-up mode.

[0011] Furthermore, the camera module controls the external storage device to transmit the image data to the data relay device, and also includes: the secondary control unit controls the external storage device to switch from being connected to the hunting camera to being connected to the main control unit, so that the external storage device transmits the image data to the data relay device through the main control unit and the high-throughput data transceiver unit.

[0012] Furthermore, before the secondary control unit controls the external memory to switch from being connected to the hunting camera to being connected to the main control unit, it also: detects whether the external memory is currently transmitting data with the hunting camera; if the external memory is transmitting data with the hunting camera, after a unit of data transmission is completed, it controls the external memory to save the data transmission progress with the hunting camera and pauses the data transmission process with the hunting camera.

[0013] Furthermore, after the camera module switches to wake-up mode, it switches from wake-up mode to low-power mode when preset sleep conditions are met. Specifically, the sub-control unit determines whether the preset sleep conditions are met at a preset judgment period. If the preset sleep conditions are met, then: the external memory switches from being connected to the main control unit to being connected to the hunting camera, the power supply to the main control unit and the high-throughput data transceiver unit is cut off, the low-throughput data transceiver unit switches to WOR mode, and the sub-control unit switches to low-power mode.

[0014] Furthermore, after the secondary control unit controls the external memory to switch from being connected to the main control unit to being connected to the hunting camera, it also: detects whether there is a paused data transmission process with the hunting camera; if there is a paused data transmission process with the hunting camera, it controls the external memory to continue executing the data transmission process.

[0015] Based on the same inventive concept, the present invention also provides a hunting camera data retrieval system, comprising: a hunting camera, a data retrieval device, and a data relay device; the data retrieval device includes: an external memory and a camera-end module disposed on the hunting camera, and a relay module disposed on the data relay device; the hunting camera transmits the captured image data to the external memory for storage; the data relay device moves to the vicinity of the hunting camera; the relay module sends a pairing signal to the camera-end module, enabling the relay module and the camera-end module to establish a communication channel; wherein, the camera-end module is normally in a low-power mode, and switches to a wake-up mode after receiving the pairing signal sent by the relay module; the camera-end module controls the external memory to transmit the image data to the data relay device; the relay module instructs the data relay device to receive the image data; the data relay device returns carrying the image data, thereby completing the data retrieval.

[0021] It should be understood that the described embodiments are merely some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of the embodiments of this application. The terminology used in the embodiments of this application is for the purpose of describing specific embodiments only and is not intended to limit the embodiments of this application. The singular forms "a," "described," and "the" used in the embodiments of this application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. It should be understood that the embodiments of this application are not limited to the precise structures described above and shown in the drawings, and various modifications and changes can be made without departing from their scope. The scope of the embodiments of this application is limited only by the appended claims.

[0022] This invention uses drones as data relay stations to retrieve data stored in hunting cameras, replacing human staff. The basic concept is as follows: the drone flies to the vicinity of the hunting camera, establishes a communication connection with the camera, and synchronizes the data from the hunting camera to the drone's memory; then the drone carries the data from the hunting camera back to the control center, thus completing the data retrieval.

[0023] However, the inventors discovered that most hunting camera manufacturers do not provide an open data interface for the camera's built-in memory, preventing drones from directly accessing the camera's data. To address this, the inventors studied the storage structure of hunting cameras and found that the built-in memory capacity is typically limited, insufficient to meet data storage needs. Therefore, most hunting cameras also include an SD card (Secure Digital Memory Card) slot. By inserting an external SD card into the slot, the hunting camera can save captured image data to the external SD card, thereby expanding its data storage capacity. While drones cannot directly access the data in the hunting camera's internal memory, they can access data from the external SD card. Therefore, this invention allows the hunting camera to store image data on an SD card, and the drone retrieves the image data by reading the SD card.

[0024] Furthermore, due to the difficulty of charging in forest environments, the hunting camera remains in low-power mode most of the time to conserve energy, only switching to wake-up mode upon receiving a wake-up signal. To adapt to applications with limited power, the data retrieval device of this invention also features normal sleep mode and remote activation by the drone.

[0025] Please see Figure 1 , Figure 1This is a schematic diagram of the hunting camera data retrieval system of the present invention. The hunting camera data retrieval system of the present invention includes: a hunting camera 1, a data retrieval device 2, and a data relay device 3. The data retrieval device 2 includes: an external storage device 21, a camera-end module 22 mounted on the hunting camera 1, and a relay-end module 23 mounted on the data relay device 3. The data retrieval device 2 is the remotely activated hunting camera data retrieval device of the present invention. The hunting camera 1 is provided with an external storage interface. The external storage device 21 is installed on the external storage interface of the hunting camera 1. The camera-end module 22 is electrically connected to the external storage device 21 and is used to control the external storage device 21. The relay-end module 23 is paired with the camera-end module 22. Through the communication channel between the relay-end module 23 and the camera-end module 22, signal communication and data transmission between the external storage device 21 and the data relay device 3 can be completed.

[0026] Specifically, the external storage device 21 can be any type of external storage device such as an SD card, TF card, USB flash drive, floppy disk, or optical disk. Its type and model depend on the external storage interface provided by the hunting camera 1. This invention does not limit the type and model of the external storage device. In this embodiment, since the external storage interface provided by the hunting camera 1 is an SD card slot, the external storage device 21 is an SD card.

[0027] Specifically, the data relay device 3 can be any intelligent device with mobility and data reading / writing capabilities, such as a drone, unmanned vehicle, robot, or robotic dog. Considering the complexity of the forest environment, it is difficult to move to the vicinity of the hunting camera via ground routes; therefore, the data relay device 3 in this embodiment is preferably a drone.

[0028] Please see Figure 2 , Figure 2 This is a schematic diagram illustrating the workflow of the hunting camera data retrieval system of the present invention. The workflow of the hunting camera data retrieval system of the present invention for retrieving image data captured by the hunting camera 1 is as follows:

[0029] S0, the hunting camera 1 transmits the captured image data to the external memory 21 for storage.

[0030] S1, the data relay device 3 moves from the control center to the vicinity of the hunting camera.

[0031] S2, the relay module 23 sends a pairing signal to the camera module 22 to establish a communication channel with the camera module 22. Specifically, the relay module 23 broadcasts the pairing signal near the hunting camera via radio waves. After receiving the pairing signal, the camera module 22 within the signal range replies with a pairing response signal to the relay module 23, thereby establishing a wireless communication channel with the relay module 23 that sent the pairing signal.

[0032] S3, the camera module 22 controls the external memory 21 to transmit the image data stored therein to the data relay device 3 through the camera module 22 and the relay module 23.

[0033] S4, under the control of the relay module 23, the data relay device 3 receives the image data transmitted by the external memory 21.

[0034] S5, the data transfer device 3 carries the image data back to the control center, thereby completing the data retrieval.

[0035] Furthermore, due to the difficulty of charging in forest environments, the hunting camera 1 operates in low-power mode most of the time to conserve energy, switching to wake-up mode only upon receiving a wake-up signal. For example, when the sensor on the hunting camera 1 detects the presence of wild animals, the sensor sends a wake-up signal to the hunting camera 1, causing it to switch from low-power mode to wake-up mode and begin capturing image data. Since image data is high-throughput data, transmitting it consumes significant energy. The hunting camera 1 can only transmit data with the data relay device 3 when switched to wake-up mode. Therefore, step S2 specifically includes: S21, the relay module 23 sends a pairing signal to the camera module 22. S22, upon receiving the pairing signal, the camera module 22 sends a wake-up signal to the hunting camera 1 via the external memory 21, causing the hunting camera 1 to switch to wake-up mode. S23, upon receiving the pairing signal, the camera module 22 simultaneously replies with a pairing response signal to the relay module 23, thereby establishing a communication channel with the relay module 23.

[0036] Furthermore, since the camera module 22 of the present invention is mounted on the hunting camera 1 and shares a power supply with it, in order to save power consumption, the camera module 22 of the present invention also needs to have the function of intelligently switching between low-power mode and wake-up mode. For this purpose, the camera module 22 is normally in low-power mode, and after step S21 (i.e., after receiving the pairing signal sent by the relay module 23), it switches to wake-up mode; it only returns to low-power mode when the preset sleep conditions are met.

[0037] Please see Figure 3 , Figure 3 This is a schematic diagram of the internal structure of the camera module of the remotely activated hunting camera data retrieval device of the present invention. The camera module 22 of the present invention specifically includes: a main control unit M1, a high-throughput data transceiver unit M2, a low-throughput data transceiver unit M3, and a secondary control unit M4.

[0038] The main control unit M1 is used to read image data from the external memory 21, preprocess the image data, and then transmit it to the high-throughput data transceiver unit M2. The high-throughput data transceiver unit M2 is used to transmit the preprocessed image data in the form of radio waves, enabling the data relay device 3 to receive the image data through the relay module 23. The main control unit M1 is also used to control the operation of the high-throughput data transceiver unit M2 in transmitting the preprocessed image data. In one embodiment, the high-throughput data transceiver unit M2 is a Wi-Fi chip and / or a Bluetooth chip.

[0039] The low-throughput data transceiver unit M3 is used to receive the pairing signal sent by the relay module 23 and forward the received pairing signal to the secondary control unit M4. The secondary control unit M4 controls the power supply of the main control unit M1 and the high-throughput data transceiver unit M2 according to the pairing signal, so that the camera module 22 switches between low-power mode and wake-up mode.

[0040] Specifically, the low-throughput data transceiver unit M3 has a WOR (Wake on Radio) mode. In WOR mode, the low-throughput data transceiver unit M3 detects the presence of a radio-based pairing signal at a preset scan cycle. If a pairing signal is detected, it enters wake-up mode; during the remaining time outside the preset scan cycle, it is in low-power mode. In one embodiment, the low-throughput data transceiver unit M3 is a LoRa chip.

[0041] Please see Figure 4 , Figure 4 This is a schematic diagram illustrating the workflow of the main control unit, high-throughput data transceiver unit, low-throughput data transceiver unit, and secondary control unit in the camera module of the present invention. The workflow of the main control unit M1, high-throughput data transceiver unit M2, low-throughput data transceiver unit M3, and secondary control unit M4 includes the following steps:

[0042] SA0, the camera module 22 is initially in low power mode. At this time, the secondary control unit M4 cuts off the power supply to the main control unit M1 and the high-throughput data transceiver unit M2. The secondary control unit M4 itself is in low power mode, and the low-throughput data transceiver unit M3 is in WOR mode.

[0043] Because the main control unit M1 and the high-throughput data transceiver unit M2 consume a lot of power, in order to save energy, the secondary control unit M4 cuts off the power supply to the main control unit M1 and the high-throughput data transceiver unit M2 when image data transmission is not required. Meanwhile, the power consumption of the secondary control unit M4 and the low-throughput data transceiver unit M3 is quite low in low-power mode and WOR mode. Therefore, the power consumption of the camera module 22 in low-power mode (below 70μA) will hardly burden the power supply of the hunting camera 1.

[0044] SA1, when the low-throughput data transceiver unit M3 is in WOR mode, it detects whether a pairing signal exists at a preset scan cycle.

[0045] SA2, if the low-throughput data transceiver unit M3 detects a pairing signal, the low-throughput data transceiver unit M3 switches from WOR mode to wake-up mode, and at the same time forwards the pairing signal to the sub-control unit M4.

[0046] SA3, after receiving the pairing signal, the secondary control unit M4 switches from low power mode to wake-up mode, and at the same time restores the power supply to the main control unit M1 and the high-throughput data transceiver unit M2, so that the main control unit M1 and the high-throughput data transceiver unit M2 are powered on and working. At this time, the camera module 22 switches to wake-up mode.

[0047] SA4, the secondary control unit M1 controls the external memory 21 to switch from "connected to the hunting camera 1" to "connected to the main control unit M1".

[0048] Furthermore, to prevent data integrity issues from occurring when the hunting camera 1 is transmitting data with the external memory 21 during step SA4, a step is included before step SA4: the sub-control unit M4 detects whether the external memory 21 is transmitting data with the hunting camera 1; if the external memory 21 is transmitting data with the hunting camera 1, after a unit of data transmission is completed, the external memory 21 is controlled to save the data transmission progress with the hunting camera 1 and the data transmission process with the hunting camera 1 is paused.

[0049] SA5, the main control unit M1 reads the image data stored in the external memory 21, performs preprocessing such as compression, encoding and protocol conversion on the image data, and transmits the preprocessed image data to the high-throughput data transceiver unit M2.

[0050] SA6, the high-throughput data transceiver unit converts the preprocessed image data into radio waves for transmission, so that the data relay device 3 receives the image data through its relay module 23.

[0051] Because the main control unit M1 reads the image data in the external storage 21 and transmits the image data to the data relay device 3 through the high-throughput data transceiver unit M2, the external storage 21 is connected to the main control unit M1, that is, it is connected to the data relay device 3 through the main control unit M1 and the high-throughput data transceiver unit M2.

[0052] SA7, the secondary control unit M4 determines whether a preset sleep condition is met at a preset judgment period. In this embodiment, the preset sleep condition is: a preset waiting time after the communication channel between the camera module 22 and the relay module 23 disappears. After obtaining the image data, the data relay device 3 leaves the hunting camera 1 and returns to the control center, causing the connection between the camera module 22 and the relay module 23 to be interrupted due to the long distance (i.e., the communication channel disappears). Therefore, after the preset waiting time after the communication channel between the camera module 22 and the relay module 23 disappears, the secondary control unit M4 can determine that the data transmission has been completed, and the camera module 22 should enter a low-power mode.

[0053] SA8, if the preset sleep conditions are met, the secondary control unit M4 controls the external memory 21 to switch from "connected to the main control unit M1" to "connected to the hunting camera 1", then cuts off the power supply to the main control unit M1 and the high-throughput data transceiver unit M2, causing the low-throughput data transceiver unit M3 to return from wake-up mode to WOR mode, and finally returns itself from wake-up mode to low-power mode. At this time, the entire camera module 22 returns to low-power mode.

[0054] Furthermore, after the secondary control unit M4 controls the external memory 21 to switch from being connected to the main control unit M1 to being connected to the hunting camera 1, it also detects whether there is a paused data transmission process with the hunting camera 1; if there is a paused data transmission process with the hunting camera 1, it controls the external memory 21 to continue executing the data transmission process.

[0055] Furthermore, after the relay module 23 and the camera module 22 establish a communication channel, the data relay device 3 can also send a command signal to the camera module 22 through the relay module 23. Upon receiving the command signal, the low-throughput data transceiver unit M3 of the camera module 22 forwards the command signal to the hunting camera 1 through the secondary control unit M4 and the external memory 21. The hunting camera 1 responds accordingly to the command signal, thereby achieving remote control of the hunting camera 1. For example, if you want to adjust a certain shooting parameter of the hunting camera 1, the conventional approach is to adjust the shooting parameter by operating the buttons on the hunting camera 1. However, in this embodiment, the relay module 23 mounted on the drone (i.e., the data relay device 3) can send a command signal containing "adjust shooting parameters," enabling remote adjustment of shooting parameters without being physically present at the site.

[0056] This invention offers the following technical advantages: 1. This invention uses a data relay device (drone) to retrieve image data captured by hunting cameras deep in the forest. Compared to manual retrieval, this method is more cost-effective, safe, and efficient. 2. Addressing the limitation of existing hunting cameras in directly accessing their built-in memory, this invention designs a data transmission device based on external memory. This data transmission device is applicable to any hunting camera with an external memory interface, making it widely applicable. Furthermore, since this data transmission device is an external accessory for the hunting camera, it requires no modification to the existing camera structure, resulting in very low modification costs. This solves the problem of remote data retrieval from hunting cameras with relatively low equipment upgrade and maintenance costs, offering high cost-effectiveness. 3. After installing the data transmission device of this invention, the hunting camera's external memory can flexibly switch between "connected to the hunting camera" and "connected to other devices (data relay device)" without risking data loss during switching. 4. The present invention also designs a mechanism for intelligent switching between low-power mode and wake-up mode for the camera module of the data transmission device, which greatly reduces the power consumption of the camera module and adapts to the application scenario of hunting camera with limited power.

[0057] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and the present invention also intends to include these modifications and variations.
