Description

Technical Field

[0001] The present invention relates to the technical field of floating rock fishing electronic floats, and particularly relates to an electronic float device based on attitude sensing and low-power control. Background Art

[0002] Traditional rock fishing floats have the following defects: 1. Single function: Conventional fixed-color-source floats rely on manual observation of the actions of the Awa floats. At night and at long distances, it is impossible to accurately judge the signal of the fish pulling the float down by the fixed color source. 2. Insufficient sensitivity: The mechanical structure is easily interfered by wind and waves, and the misjudgment rate is high. The biting signal depends on physical actions. It is necessary to judge the biting by mechanical movements such as the sinking and tilting of the floating wave. When the light is insufficient at night, weak signals are easily missed. It can only reflect the physical pulling of the fishing line and is not sensitive to the biting of light-biting fish (such as tentative pecking at bait). 3. Short battery life: Electronic floats often require frequent battery replacement due to high power consumption. 4. Poor environmental adaptability: The recognition rate of traditional floating waves drops sharply under low light, surging waves or long-distance conditions. The color-changing floating wave strengthens the signal through color light contrast and reduces environmental interference. To solve the above problems, the present invention provides an electronic float device based on attitude sensing and low-power control. Summary of the Invention

Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Embodiment 1:

[0028] As Figures 1 to 4 shown, the present invention provides an electronic float device based on attitude sensing and low-power consumption control, including an upper housing 1 and a lower housing 2 that are threadedly connected to form a sealed housing. Specifically, a sealing ring A 11 is sleeved outside the threaded portion at the end of the upper housing 1, and the sealing ring A 11 is located between the upper housing 1 and the lower housing 2 for sealing the housing.

[0029] An electronic control device is installed inside the upper housing 1. The electronic control device includes an electronic control board 4 and a battery assembly. The electronic control board 4 integrates a main control unit 41, an attitude sensor 42, and two LED lights 43. The battery assembly includes a battery board 51 and two batteries 52. The battery board 51 is installed inside the upper housing 1 to form a circuit cavity. The electronic control board 4 is installed on the battery board 51 and is located inside the circuit cavity. The sealed circuit cavity ensures a good working environment for the battery board 51. The battery 52 is installed in a battery holder outside the electronic control board 4. The battery 52 uses a CR425 battery (200 mAh) to support continuous operation for ≥120 hours, which is beneficial for the long-term standby of the electronic float. Specifically, the main control unit 41 is an STM32C011F4U6 microcontroller, which runs with low power consumption and solves the problem of frequent battery replacement of the electronic float due to high power consumption. The attitude sensor 42 is an LIS2DW12TR three-axis accelerometer, and its parameters are set as follows: range: ±8g, sampling rate 50 Hz, high-pass filter cut-off frequency 0.2 Hz, which is used to detect the acceleration of the electronic float in the vertical direction to determine whether a fish has taken the bait. The two LED lights 43 are driven by an LBSS8402 driving module. As Figure 5 shown, the LBSS8402 driving module adopts a complementary push-pull MOS structure, and a single pin controls the alternating lighting of the two LED lights 43. More specifically, the lighting of the two LED lights 43 has a daytime mode and a nighttime mode. In the nighttime mode, the green LED light 43 that is lit is constantly on. When the debounce mechanism described below is satisfied, it switches to the red LED light 43 that is lit and flashes to remind the user that a fish has taken the bait.

[0030] Please refer to Figures 2 to 4 shown, the main control unit 41 controls the on / off of the two LED lights 43 through a built-in dynamic acceleration threshold algorithm. Through the dynamic acceleration threshold algorithm, it can adapt to the wind and surge environment, accurately identify when a fish has taken the bait, and has a low false alarm rate. Specifically, the dynamic acceleration threshold algorithm includes baseline calibration, trigger conditions, and a debounce mechanism;

[0031] Baseline calibration: After the electronic float enters the water, within the time T0, multiple accelerations of the electronic float are collected through the attitude sensor 42, and the main control unit 41 calculates the mean value u of the water wave acceleration. Among them, T0 is the time for testing the water wave acceleration in the water area at this location. The setting of T0 varies according to different users' requirements for sensitivity. The longer the time, the closer the acceleration of the float in the vertical direction affected by the water wave collected is to the actual situation, adapting to harsh fishing environments, and can effectively identify when a fish has taken the bait even in strong winds and waves. In this embodiment, the provided T0 is 5 minutes, which is the time obtained by the applicant through multiple tests and can meet the requirements of users.

[0032] Trigger condition: After T0 time, the acceleration a of the electronic float is measured in real time through the attitude sensor 42; if au>2g and the duration is greater than T1, the main control unit 41 satisfies the trigger condition once cumulatively; the influence of the acceleration caused by water waves is deducted from the actual measured electronic float acceleration a. At this time, the electronic float acceleration is still greater than 2g, and it is considered that there is a high probability that the fish is biting the hook; when this situation lasts for T1, it can be determined that it is an indicator of the fish biting the hook; the duration T1 here is set to 5 milliseconds, which is the data that has achieved better results after many tests.

[0033] De-bounce mechanism: If the main control unit 41 calculates that the trigger condition is met three times within the time T2, it controls the LBSS8402 driver module to drive the two LED lights 43 to switch on and off; that is, when the trigger condition is met three times within the time T2, it can be determined that the fish has taken the hook deeply. At this time, the main control unit 41 controls the red LED light 43 to flash to remind the user; the time interval T2 here is set to 5 seconds; this value is the data that has achieved better results after multiple tests.

[0034] See also Figure 1 and Figure 2 As shown, the counterweight 3 is snap-fitted and installed on the bottom surface of the lower shell 2; the counterweight 3 is detachable and replaceable, which can broaden the adaptability scenario, match the draft depth of the float, and be suitable for fishing grounds in more waters, thereby improving adaptability. Specifically, the top of the upper shell 1 is integrally connected to the threading tube 12, and the top of the threading tube 12 is coaxially connected to the magnetic ring stepped hole opened at the top of the upper shell 1; the threaded portion at the end of the threading tube 12 is threadedly connected to the internal threaded tube 121, and the internal threaded tube 121 is installed in the pipe groove opened at the bottom of the lower shell 2; the outer bottom of the lower shell 2 is provided with a magnetic ring stepped hole coaxially connected to the pipe groove, and a magnetic ring 13 is installed in the magnetic ring stepped hole; in actual use, the fishing line can be passed through the inner ring of one magnetic ring 13 into the threading tube 12 and out from the inner ring of the magnetic ring 13 at the other end, thereby realizing the connection with the fishing line, which is convenient and practical. More specifically, two sealing rings B122 are sleeved on the outside of the internal threaded tube 121 to improve the sealing performance; an annular counterweight groove is coaxially opened on the outside of the bottom tube groove in the lower shell 2, and the counterweight block 3 is matched and installed in the annular counterweight groove; the electronic float draft can be adjusted by changing the counterweight block 3 of different density, and it can adapt to the water environment of different fishing grounds, which is convenient and practical.

[0035] Example 2:

[0036] On the basis of retaining all the technical features in the specific embodiment one, in this embodiment, a ring for threading is installed at the center position of the outer bottom of the lower shell 2, and a ring groove is opened at the center position of the outer bottom of the lower shell 2. The connecting column integrally connected to one end of the ring is fixedly installed in the ring groove. In actual use, the fishing line only needs to pass through the ring to achieve a stable connection with the electronic float, which is convenient and practical.

[0037] Obviously, those skilled in the art can make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these modifications and variations.
