Description

Technical Field

[0001] This invention relates to the field of electronic float technology for rock fishing, specifically to an electronic float device based on attitude sensing and low power consumption control. Background Technology

[0002] Traditional rock fishing floats have the following drawbacks: 1. Limited functionality: Conventional fixed-color floats rely on manual observation of the float's movement, making it difficult to accurately determine the sinking signal of a fish pulling the float at a distance, especially at night. 2. Insufficient sensitivity: The mechanical structure is easily affected by wind and waves, resulting in a high misjudgment rate. Hooking signals rely on physical movements. The bite must be detected through the sinking and tilting of the float, making it easy to miss weak signals in low light conditions. They only reflect the physical pull of the fishing line and are not sensitive to light bites (such as tentative nibbling). 3. Short battery life: Electronic floats often require frequent battery replacements due to high power consumption. 4. Poor environmental adaptability: Traditional floats have drastically reduced visibility in low light, surging waves, or at long distances. Color-changing floats enhance the signal through color contrast, reducing environmental interference. To solve these problems, this invention provides an electronic float device based on attitude sensing and low-power control. Summary of the Invention

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1:

[0028] like Figures 1 to 4 As shown, the present invention provides an electronic float device based on attitude sensing and low power consumption control, including an upper shell 1 and a lower shell 2 formed by threaded connection to form a sealed shell. Specifically, a sealing ring A11 is sleeved on the outside of the threaded portion at the end of the upper shell 1. The sealing ring A11 is located between the upper shell 1 and the lower shell 2 to seal the shell.

[0029] The upper housing 1 houses the electronic control equipment, which includes an electronic control board 4 and a battery pack. The electronic control board 4 integrates a main control unit 41, an attitude sensor 42, and two LEDs 43. The battery pack includes a battery panel 51 and two batteries 52. The battery panel 51 is installed inside the upper housing 1 to form a circuit cavity. The electronic control board 4 is mounted on the battery panel 51 and located within the circuit cavity. The sealed circuit cavity ensures a good working environment for the battery panel 51. The batteries 52 are installed in battery holders outside the electronic control board 4. The batteries 52 are CR425 batteries (200mAh) that support continuous operation for ≥120 hours, which is beneficial for the electronic float's long standby time. Specifically, the main control unit 41 is an STM32C011F4U6 microcontroller, which operates with low power consumption, solving the problem of frequent battery replacements caused by high power consumption in electronic floats. The attitude sensor 42 is a LIS2DW12TR triaxial accelerometer with the following parameters: range: ±8g, sampling rate: 50Hz, high-pass filter cutoff frequency: 0.2Hz. It is used to detect the vertical acceleration of the electronic float to determine if a fish has taken the bait. The two LED lights 43 are driven by an LBSS8402 driver module; for example... Figure 5 As shown, the LBSS8402 driver module adopts a complementary push-pull MOS structure, and a single pin controls the alternating lighting of the two LEDs 43. More specifically, the two LEDs 43 have daytime and nighttime modes. In nighttime mode, the green LED 43 is constantly lit. When the anti-shake mechanism described below is met, it switches to flashing red LED 43 to alert the user that the fish has taken the bait.

[0030] Please see Figures 2 to 4 As shown, the main control unit 41 controls the switching of the two LED lights 43 through a built-in dynamic acceleration threshold algorithm. This algorithm adapts to wind and surge conditions, accurately identifies fish bites, and has a low false alarm rate. Specifically, the dynamic acceleration threshold algorithm includes baseline calibration, triggering conditions, and a debounce mechanism.

[0031] Baseline calibration: After the electronic float enters the water, multiple accelerations of the electronic float are collected by the attitude sensor 42 within a time period T0, and the average value u of the water wave acceleration is calculated by the main control unit 41; where T0 is the time for testing the water wave acceleration in the water area at that location; the setting of T0 varies depending on the sensitivity requirements of different users. The longer the time, the closer the vertical acceleration of the float under the influence of water waves is to the actual situation, adapting to harsh fishing environments and effectively identifying fish bites even in strong winds and waves; the T0 provided in this embodiment is 5 minutes, which is a time that the applicant has obtained after multiple tests and can meet the user's requirements.

[0032] Triggering condition: After time T0, the acceleration a of the electronic float is measured in real time by attitude sensor 42; if a > 2g and the duration is greater than T1, the main control unit 41 will satisfy the triggering condition once; after deducting the effect of acceleration caused by water waves from the actual measured acceleration a of the electronic float, the acceleration of the electronic float is still greater than 2g, and it is considered that there is a high probability that a fish has taken the bait; when the duration of this situation is T1, it can be determined that a fish is taking the bait; the duration T1 here is set to 5 milliseconds, and this value is data that has achieved good results after multiple tests.

[0033] Anti-shake mechanism: The main control unit 41 calculates that if the trigger condition is met 3 times within 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 3 times within time T2, it can be determined that the fish has taken the bait. At this time, the main control unit 41 controls the red LED light 43 to flash frequently to remind the user. The time interval T2 here is set to 5 seconds. This value is data that has achieved good results after multiple tests.

[0034] Please see Figure 1 and Figure 2 As shown, a counterweight 3 is snapped onto the inner bottom surface of the lower shell 2; the detachable and replaceable counterweight 3 can broaden the adaptability to various scenarios, match the draft of the float, and be suitable for fishing grounds in more waters, thus improving adaptability. Specifically, a line guide tube 12 is integrally connected to the top of the inner shell 1, and the top of the line guide tube 12 is coaxially connected to the magnetic ring stepped hole opened on the top of the outer shell 1; the threaded part at the end of the line guide tube 12 is threaded to an internal thread tube 121, which is installed in a groove opened on the bottom of the inner shell 2; a magnetic ring stepped hole coaxially connected to the groove is opened on the bottom of the outer shell 2, and a magnetic ring 13 is installed in the magnetic ring stepped hole; in actual use, the fishing line can pass through the inner ring of one magnetic ring 13 into the line guide tube 12 and out through the inner ring of the other magnetic ring 13 to achieve connection with the fishing line, which is convenient and practical. More specifically, two sealing rings B122 are fitted on the outside of the internally threaded tube 121 to improve the sealing performance; an annular counterweight groove is opened coaxially on the outside of the bottom tube groove inside the lower shell 2, and the counterweight block 3 is matched and installed in the annular counterweight groove; the draft of the electronic float can be adjusted by changing the counterweight block 3 of different densities, and it can adapt to the aquatic environment of different fishing grounds, which is convenient and practical.

[0035] Example 2:

[0036] While retaining all the technical features of the first specific embodiment, in this embodiment, a hanging ring for threading the line is installed at the center of the outer bottom of the lower housing 2. A hanging ring groove is opened at the center of the outer bottom of the lower housing 2. A connecting post integrally connected to one end of the hanging ring is fixedly installed in the hanging ring groove. In actual use, the fishing line can be stably connected to the electronic float simply by passing through the hanging ring, which is convenient and practical.

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