Description

Technical Field

[0001] The invention relates to the field of electronic floats, and in particular to a vertical electronic float capable of setting multiple levels of float tail brightness and having multiple hook bite reminder functions. Background Art

[0002] In order to fish at night and in poor lighting conditions, people use electronic floats that can make the tail of a vertical float glow. The tail of a vertical electronic float is mostly made of optical fiber material, and usually different colored circular vertical grids are marked on the tail as the "eye" of the float. By using a micro battery to drive a light-emitting diode to illuminate the tail of the float made of optical fiber material, the eye of the float can be clearly displayed in dark environments such as at night, making it convenient for people to watch the float and fish at night.

[0003] However, the brightness of the tail of a common electronic float cannot be adjusted. The brightness of the tail is positively correlated with the voltage of the micro-battery. The electronic float commonly uses a needle-shaped micro-battery with a diameter of about 3.5 mm, and its model is usually CR425, CR316 or CR322. The needle-shaped micro-battery is small in size and light in weight, but has a small capacity and a large internal resistance. The new micro-battery is used in a common electronic float. The voltage and current of the micro-battery change over time, such as Figure 1 As shown. Figure 1It can be seen that the voltage of the micro battery and the working current of the electronic float change greatly during the whole fishing process, especially in the first 1-2 hours of using a new micro battery. The change of the micro battery voltage will cause the brightness of the electronic float tail to change significantly. When the new battery is just used, the battery voltage is high because the power is very sufficient, so the brightness of the electronic float tail is very high. At this time, if the ambient light at the fishing location is very dark, the tail of the electronic float will appear very dazzling and the float will not be clearly visible, causing discomfort to the angler. The optimal tail brightness will vary depending on the individual situation of the angler and the lighting conditions of the fishing environment. Normally, in a fishing environment where the sky is not completely dark after dusk, the tail of the float needs a high brightness so that the angler can see the float clearly; in a fishing environment where the sky is completely dark but there is some lighting, the tail of the float needs a medium brightness; in a completely dark fishing environment where the sky is completely dark and there is no lighting around, the tail of the float needs a lower brightness to have a better viewing effect. If the tail of the float appears high brightness or even super high brightness at this time, the angler will obviously feel the glare of the tail of the float and cannot see the float clearly, thus missing the best time to lift the rod. Normally, in order to have a high tail brightness when the battery voltage is low so that the float of the electronic float can be seen clearly, the designer of the electronic float generally increases the working current of the light-emitting diode to increase the brightness of the tail of the float. However, when the battery voltage is high, the working current and the brightness of the tail of the electronic float will inevitably increase further, which not only makes the tail of the electronic float more dazzling when the battery voltage is high, but also wastes the power of the micro battery, reduces the working time of the micro battery, and increases the cost of the angler to buy the micro battery.

[0004] With the advancement of science and technology, electronic floats using gravity sensing technology have appeared in recent years. When a fish bites the bait and the float moves slightly up and down, the tail of the electronic float emits a red light, reminding the angler to use the pole to stab the fish. The electronic float using gravity sensing technology reduces the difficulty of fishing, greatly improves the efficiency of fishing, and is widely welcomed by anglers. At present, the electronic floats used by anglers are basically this kind of gravity-sensing electronic floats that can change color when biting the hook. However, the common gravity-sensing electronic floats that change color when biting the hook have a relatively simple reminder function, which only has the reminder function of changing color or flashing when biting the hook, and cannot reflect the strength and speed of the fish biting the bait. Compared with fishing with traditional floats, it is a bit like fool-style fishing, lacking the initiative of the angler, reducing the fun of observing the mark fishing, and is disliked by many fishing masters.

[0005] Therefore, we propose a vertical electronic float with multiple settings of float tail brightness and multiple hook bite reminder functions to solve the problems raised in the above-mentioned background technology. Summary of the invention

[0006] The purpose of the present invention is to provide a vertical electronic float with multiple hook bite reminder functions, the brightness of the float tail of which can be independently set according to the lighting conditions of the fishing environment, and after the brightness of the float tail is set, the brightness of the float tail is basically not affected by the voltage change of the battery.

[0007] In order to solve the above technical problems, the present invention is implemented through the following technical solutions: an electronic float with adjustable brightness, including a float body assembly and a float tail assembly. The float body assembly includes a float body with internal threads and a float foot, and the float foot is fixed to the float body by bonding. The float tail assembly includes a micro battery, an external thread of a float tail seat, a sealing ring, a battery plastic insulating fixing ring, a battery positive terminal contact electrode, a battery negative terminal contact electrode, a gravity sensing control circuit board, a non-polar two-color light-emitting diode, a float tail seat, an optical fiber float tail, and a float tail float eye. The micro battery is fixed to the inside of the lower end of the float tail seat by friction, and the gravity sensing control circuit board is powered by the contact electrodes on the gravity sensing control circuit board. The gravity sensing control circuit board is located inside the float tail seat, and includes a sensor that can sense the floating direction, displacement, angle, and / or force changes of the vertical electronic float and a microprocessor that controls the light-emitting diode to emit light. The light-emitting diode is fixed to the upper part of the gravity sensing control circuit board. The optical fiber tail is fixed on the upper part of the tail seat, and the bottom of the optical fiber tail is close to the light-emitting surface of the light-emitting diode, which guides the light of the light-emitting diode to the inside of the entire optical fiber tail, so that the optical fiber tail emits light as a whole. The light-emitting diode emits two colors of light, one color of light is used to display the float, and the other color of light is used for alarm and reminder indication. The sealing ring is mounted on the outside of the lower end of the tail seat. The tail assembly is connected to the float body assembly through an external thread to form a detachable sealing connection. The sealing ring is used to prevent water from entering the inside of the float.

[0008] Preferably, the light emitting diode is an electrodeless two-color light emitting diode with a diameter of 3 mm. The electrodeless two-color light emitting diode can emit two colors of light by applying voltages of different polarities to two electrodes.

[0009] Preferably, the electrodeless two-color light emitting diode emits red and green light, the green light is used to indicate drifting, and the red light is used for alarm and reminder indication.

[0010] An electronic float with adjustable brightness, the working principle of which is as follows: according to actual tests, when the working voltage value of the micro-battery is approximately equal to 2.4V, the brightness of the tail of the commonly used electronic float is relatively high brightness, which is suitable for use in an environment where the sky is not completely dark after dusk; when the working voltage value of the micro-battery is approximately equal to 2.32V, the brightness of the tail of the commonly used electronic float is medium brightness, which is suitable for use in an environment where the sky is completely dark but there is some lighting; when the working voltage value of the micro-battery is approximately equal to 2.25V, the brightness of the tail of the commonly used electronic float is relatively low brightness, which is suitable for use in a very dark environment where there is no lighting at the fishing position. The electronic float of the present invention uses 2.4V, 2.32V and 2.24V as the brightness voltage preset values ​​of the three brightness gears of relatively high brightness, medium brightness and relatively low brightness, respectively. Taking the medium brightness gear as an example, during the operation of the electronic float, the microprocessor in the electronic float of the present invention constantly monitors the working voltage value of the micro battery during the entire fishing process. When the working voltage value of the micro battery is higher than the brightness voltage preset value of the current brightness gear (2.32V, corresponding to the medium brightness gear), the microprocessor uses pulse width modulation technology (PWM) to drive the green light emitting diode used to display the float to emit light, so as to reduce the average working voltage of the green light emitting diode, thereby reducing the average working current of the green light emitting diode to achieve the purpose of reducing the brightness of the green light emitting diode. The brightness of the green light emitting diode is positively correlated with the duty cycle (PWM value) of the positive pulse driving the light emitting diode. The positive pulse signal with a duty cycle (PWM value) equal to 100% corresponds to the highest brightness of the green light emitting diode. The microprocessor uses a specific calculation method to make the brightness of the green light-emitting diode driven by pulse width modulation technology (PWM) basically consistent with the brightness of the green light-emitting diode when the voltage value of the micro-battery is equal to the brightness voltage preset value (2.32V) of the current brightness gear (PWM value = 100%) when the working voltage value of the micro-battery is higher than the brightness voltage preset value (2.32V) of the current brightness gear. Thus, the function of setting the brightness of the tail of the electronic float is realized, and when the voltage value of the micro-battery is higher than the brightness voltage preset value (2.32V) of the current brightness gear, the microprocessor always monitors the voltage value of the micro-battery and adjusts the duty cycle (PWM value) of the positive pulse driving the light-emitting diode in real time according to the voltage value of the micro-battery. Regardless of how the voltage value of the micro-battery changes, the brightness of the tail of the electronic float can basically remain constant. The electronic float of the present invention is powered off within 8 seconds after the electronic float is powered on to realize the sequential cyclic switching of the three brightness gears of high brightness, medium brightness and low brightness, so as to meet the needs of the fishing environment with different lighting conditions at dark.

[0011] The gravity sensing control circuit board in the tail assembly of the electronic float of the present invention is provided with a sensor capable of sensing the direction of the float movement and the change of acceleration, and the sensor transmits the motion state data of the electronic float to the microprocessor. When the underwater fish bites the bait and causes the float to move slightly up and down, the microprocessor can drive the red light emitting diode used for alarm and reminder indication to emit light according to the motion state of the float, and perform a variety of alarm reminder indications. According to the different accelerations of the float moving up and down, the light emitting state of the red light emitting diode will also change accordingly. When the acceleration of the float moving up and down is very small, the red light emitting diode does not emit light to avoid interference signals; when the acceleration of the float moving up and down is small, the red light emitting diode only emits light briefly for about 0.1 seconds, emitting a slight red light to remind the angler to concentrate and not affect the angler to observe the change of the float; when the acceleration of the float moving up and down is large, the red light emitting diode continues to emit light for about 1.5 seconds, reminding the angler to consider lifting the rod to stab the fish; when the acceleration of the float moving up and down is large, the red light emitting diode flashes continuously for about 2 seconds, reminding the angler to lift the rod to stab the fish.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The electronic float of the present invention can be set to three different brightnesses of the float tail, namely high brightness, medium brightness and low brightness, when fishing at dark, so as to adapt to fishing environments with different lighting conditions, thereby achieving the best effect of observing the float and increasing the comfort of fishing.

[0013] The electronic float of the present invention, once a certain brightness level of the float tail is set, can keep the brightness of the float tail basically constant when the operating voltage of the battery is higher than the preset value of the brightness voltage of the current brightness level, and the brightness of the float tail will not change significantly with the change of the battery operating voltage. The common electronic float will not have the situation where the light is glaring and the purpose of the float cannot be seen clearly due to the excessive brightness of the float tail, thereby improving the comfort of the angler in viewing the float.

[0014] Once a certain brightness level of the tail of the float is set, when the working voltage of the battery is higher than the preset brightness voltage value of the current brightness level, in order to achieve constant brightness of the tail of the float, the electronic float of the present invention will automatically reduce the working current of the light-emitting diode, reduce the power consumption of the electronic float at high voltage, and thus extend the working time of the micro battery. When a relatively low brightness level is used, the working time of the micro battery can be nearly doubled compared to the common electronic float, thereby reducing the battery purchase cost of the angler.

[0015] The electronic float of the present invention adopts three different lighting reminder modes of a red light emitting diode, namely, short-term lighting, continuous lighting, and continuous flashing, to indicate the magnitude of the change in the movement state of the float, which is convenient for anglers to judge the specific situation of fish biting the hook and choose the corresponding rod lifting strategy, thereby increasing the fun of fishing and avoiding fool-style fishing.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 2—8, the present invention provides a technical solution: an electronic float with adjustable brightness, including a float body component and a float tail component. The float body component includes a float foot 1, a float body 2, a float body battery compartment 3 and a float body internal thread 4. The float foot 1 and the float body 2 are fixedly connected, the float body battery compartment 3 is located at the upper part of the float body 2, and the float body internal thread 4 is used to connect the float tail component. The float tail component includes a micro battery 5, a float tail seat external thread 6, a sealing ring 7, a battery plastic insulating fixing ring 8, a battery positive terminal contact electrode 9, a battery negative terminal contact electrode 10, a gravity sensing control circuit board 11, a non-polar two-color light-emitting diode 12, a float tail seat 13, an optical fiber float tail 14, and a float tail eye 15. The float tail seat 13 is hollow inside and can accommodate the micro battery 5 and the gravity sensing control circuit board 11. The micro battery 5 is in contact with the positive contact electrode 9 and the negative contact electrode 10 of the battery on the gravity sensing control circuit board 11, and provides power for the gravity sensing control circuit board 11. The outer portion of the lower end of the float tail seat 13 is provided with an external thread 6 and a sealing ring 7 of the float tail seat, which form a separable sealed connection with the float body assembly. The stepless two-color light-emitting diode 12 is located at the upper part of the float tail seat 13, and the pins of the stepless two-color light-emitting diode 12 are welded and connected to the light-emitting diode driving pad on the gravity sensing control circuit board 11. The optical fiber tail 14 is fixedly connected to the float tail seat 13 through the upper through hole of the float tail seat 13, and the lower surface of the optical fiber tail 14 is in close contact with the upper luminous surface of the stepless two-color light-emitting diode 12. The outer surface of the optical fiber tail 14 is printed with a color or monochrome tail mesh 15. The gravity sensing control circuit board 11 is provided with a sensor IC1 and a microprocessor IC2 that can sense the floating movement direction and acceleration changes. The ADC input terminal of the microprocessor IC2 is connected to the positive contact electrode 9 of the battery. The output terminal of the PWM-1 of the microprocessor IC2 is connected to the 1st pin of the stepless two-color light-emitting diode 12, and the output terminal of the PWM-2 of the microprocessor IC2 is connected to the 2nd pin of the stepless two-color light-emitting diode 12. The microprocessor IC2 contains a data register that can be stored when the power is off, which is used as a brightness setting register that can be stored when the power is off to store the brightness voltage preset value of the current brightness gear. The present invention can set three brightness gears of high brightness, medium brightness, and low brightness. The three brightness gears correspond to three different brightness voltage preset values, respectively. These three different brightness voltage preset values ​​will be adjusted accordingly according to the production process of the electronic float and the selection of components.

[0028] Working principle: When the electronic float is in use, the micro battery 5 is inserted into the bottom of the float tail seat 13 of the float tail assembly. The micro battery 5 provides power to the gravity sensing control circuit board 11 through the contacts of the battery positive terminal contact electrode 9 and the battery negative terminal contact electrode 10 of the gravity sensing control circuit board 11. After the gravity sensing control circuit board 11 is powered on, it enters the initial setting working state. The microprocessor IC2 controls the PWM-1 pin to output a low level and controls the PWM-2 pin to output a positive pulse voltage. At this time, the 1st pin of the electrodeless two-color light-emitting diode 12 is about 0V, and the 2nd pin is a positive pulse voltage. The red light-emitting tube of the electrodeless two-color light-emitting diode 12 used for alarm and reminder indication does not emit light, and the green light-emitting tube used to display the purpose of the float emits light. Then, the microprocessor IC2 measures the working voltage of the micro battery and calculates the average value of the current voltage value (e.g., 2.9V), and reads the brightness voltage preset value of the current brightness level in the brightness setting register that can be stored during power failure (e.g., 2.4V, corresponding to high brightness). Then, the microprocessor IC2 calculates the brightness preset value of the current brightness level (e.g., 2.4V, corresponding to high brightness) according to the formula: PWM value = (brightness voltage preset value of the current brightness level (e.g. 2.4V) - brightness voltage reference value (e.g. 2.0V)) / (average value of the current voltage value (e.g. 2.9V) - brightness voltage reference value (e.g. 2.0V)) * 100% (duty cycle) = 44%.

[0029] Note: The brightness voltage reference value is about 2.0V, which varies slightly according to the performance parameters of the green LED in the electrodeless dual-color LED 12. According to the above formula, selecting a suitable brightness voltage reference value can make the brightness of the green LED of the present invention remain basically constant when the voltage of the micro battery is higher than the brightness voltage preset value of the current brightness level.

[0030] Note: The PWM value = duty cycle of the positive pulse voltage.

[0031] The microprocessor IC2 controls the duty cycle (e.g., 44%) of the positive voltage of the PWM-2 pin according to the calculated PWM value to reduce the average operating voltage of the green LED in the stepless two-color LED 12 to adjust the brightness of the green LED. During the continuous operation of the electronic float, the microprocessor IC2 continuously monitors the voltage of the battery and adjusts the duty cycle (PWM value) of the positive pulse of the PWM-2 pin at any time according to the above formula to achieve the function of setting the brightness of the green LED and keep the brightness of the tail of the float basically constant at any time when the voltage of the micro battery is higher than the preset value of the brightness voltage of the current brightness level.

[0032] After entering the initial setting working state after power-on, the microprocessor IC2 will immediately overwrite the brightness voltage preset value of the next gear (e.g. 2.32V, corresponding to medium brightness) into the brightness setting register that can be stored after power-off after reading the brightness voltage preset value of the current brightness gear (e.g. 2.4V, corresponding to high brightness) of the brightness setting register that can be stored after power-off as the temporary brightness voltage preset value of the current brightness gear. Then, after waiting for about 8 seconds of gear adjustment delay, the brightness voltage preset value of the current brightness gear (e.g. 2.4V, corresponding to high brightness) read just when powering on is overwritten into the brightness setting register that can be stored after power-off, and then the red light-emitting diode is turned on to light up for about 0.3 seconds, and the interval is about 0.2 seconds. The rhythm of light flashes for 2 seconds, indicating that it has entered the normal working state. During the approximately 8-second delay period of the initial setting working state, the red LED of the stepless two-color LED 12 will feedback the current brightness level setting, flashing 3 times at high brightness, 2 times at medium brightness, and 1 time at low brightness. The flashing rhythm of the red LED each time is about 0.5 seconds, and the interval is about 1 second.

[0033] Since the brightness setting register of the microprocessor IC2 is a data register that can store data when power is off, the brightness voltage preset value of the current brightness gear can be saved when there is no power. Therefore, if there is a power outage during the time period of the initial setting working state, the brightness setting register that can store data when power is off stores the brightness voltage preset value of the next gear (for example, 2.32V, corresponding to medium brightness) after power is off, and the brightness gear switching function is realized after power is turned on again. The three brightness gears of high brightness, medium brightness, and low brightness are switched in sequence, and the three brightness gears correspond to three different brightness voltage preset values. After entering the normal working state and then powering off, the brightness setting register that can store data when power is off stores the brightness voltage preset value of the current brightness gear (for example, 2.4V, corresponding to high brightness), so the brightness gear will not be switched, thereby realizing the memory storage function of the brightness gear after fishing is completed. If the ambient light conditions for fishing are similar again, there is no need to set the brightness gear every time the power is turned on.

[0034] The red light-emitting tube of the stepless two-color light-emitting diode 12 is used for alarm reminder indication. The microprocessor IC2 controls the PWM-1 pin to output a positive pulse voltage and controls the PWM-2 pin to output a low level. At this time, pin 1 of the stepless two-color light-emitting diode 12 is a positive pulse voltage, and pin 2 is about 0V. The green light-emitting tube of the stepless two-color light-emitting diode 12 does not emit light, and the red light-emitting tube emits light and the brightness is adjustable according to the duty cycle (PWM value) of the positive pulse voltage to provide an alarm reminder indication.

[0035] The gravity sensing control circuit board 11 in the float tail assembly is equipped with a sensor IC1 and a microprocessor IC2 that can sense the floating movement direction and acceleration changes. When the underwater fish bites the bait and causes the float to move slightly up and down, the gravity sensing control circuit board 11 can convert the slight movement state into an electrical signal, drive the red light-emitting tube to emit light, and give an alarm reminder.

[0036] According to the different maximum instantaneous relative acceleration of the float's up and down movement (after subtracting 1G of gravity acceleration), the luminous state of the red light-emitting tube of the stepless two-color light-emitting diode 12 will also change accordingly. Three different luminous reminder modes, namely short-term luminescence, continuous luminescence and continuous flashing, are used to indicate the magnitude of the change in the float's movement state, and it has a variety of hook bite reminder indication functions. When the acceleration of the float's up and down movement is very small (the maximum instantaneous relative acceleration is less than 0.05G), the red light-emitting tube of the stepless two-color light-emitting diode 12 does not emit light to avoid interference signals. When the acceleration of the float's up and down movement is small (the maximum instantaneous relative acceleration is 0.05G-0.1G), the duty cycle (PWM value) of the positive pulse voltage of pin 1 of the stepless two-color light-emitting diode 12 is set to 30%, and the red light-emitting tube of the stepless two-color light-emitting diode 12 briefly emits light for about 0.1 seconds to remind the angler to concentrate. Since the red light-emitting tube emits light dimly and for a very short time, it does not affect the angler's observation of the changes in the float. When the acceleration of the float's up and down movement is large (the maximum instantaneous relative acceleration is 0.1G-0.5G), the duty cycle (PWM value) of the positive pulse voltage of pin 1 of the stepless two-color light-emitting diode 12 is set to 60%, and the red light-emitting tube of the stepless two-color light-emitting diode 12 continues to emit light for about 1.5 seconds, reminding the angler to consider lifting the rod to stab the fish. When the acceleration of the float's up and down movement is large (the maximum instantaneous relative acceleration is greater than 0.5G), the duty cycle (PWM value) of the positive pulse voltage of pin 1 of the stepless two-color light-emitting diode 12 is set to 100%, and the red light-emitting tube of the stepless two-color light-emitting diode 12 flashes continuously for about 2 seconds with a light-emitting rhythm of about 0.3 seconds and an interval of about 0.2 seconds, reminding the angler to lift the rod to stab the fish.

The rhythm of each flashing of the red light-emitting diode is about 0.5 seconds, and the interval is about 1 second; S2. During the gear adjustment delay of about 8 seconds, if the electronic float is disconnected due to the micro battery (5) being unplugged, since the brightness voltage preset value of the current brightness gear in the brightness setting register that can be stored during power failure has been replaced by the brightness voltage preset value of the next brightness gear, when the power is turned on next time, the brightness voltage preset value of the next brightness gear is used as the brightness voltage preset value of the current brightness gear, thereby completing a brightness gear switch; the three brightness gears of high brightness, medium brightness and low brightness are switched in sequence in a cycle; S3. If the electronic float does not lose power during the gear adjustment delay of about 8 seconds, the microprocessor IC2 will overwrite the preset brightness voltage value of the current brightness gear read at power-on into the brightness setting register that can be stored when power is off, and then drive the red light emitting diode to light for about 0.3 seconds and flash quickly for 2 seconds at an interval of about 0.2 seconds, indicating that the initial setting working state has been completed and the normal working state has been entered; after entering the normal working state, the power is cut off again, and the brightness setting register that can be stored when power is off stores the preset brightness voltage value of the current brightness gear, so the brightness gear will not be switched.

3. The electronic float according to claim 1, characterized in that: After the brightness level is set, at any time when the voltage of the micro battery (5) is higher than the preset brightness voltage value of the current brightness level, the electronic float maintains the luminous brightness of the tail of the float substantially constant; the setting method of the electronic float maintaining the luminous brightness of the tail of the float substantially constant comprises the following steps: S1, the electronic float enters the initial setting working state after power-on, and the microprocessor IC2 reads the brightness voltage preset value of the current brightness level of the brightness setting register that can be stored when power is off; S2, the microprocessor IC2 reads the voltage value of the ADC input terminal of the microprocessor IC2, that is, the voltage value of the micro battery (5), and calculates the average value of the current voltage value to reduce the error; S3, the microprocessor IC2 calculates the PWM value of the PWM-2 pin of the microprocessor IC2, that is, the duty cycle of the positive pulse voltage, according to the brightness voltage preset value of the current brightness gear and the average value of the current voltage value, according to the formula: PWM value = (brightness voltage preset value of the current brightness gear - brightness voltage reference value) / (average value of the current voltage value - brightness voltage reference value) * 100%; if the average value of the current voltage value is less than the brightness voltage preset value of the current brightness gear, the PWM value is set to 100%; the brightness voltage reference value is about 2.0V, which changes slightly according to the performance parameters of the green light emitting diode in the electrodeless two-color light emitting diode 12; S4, the microprocessor IC2 controls the PWM-1 pin of the microprocessor IC2 to output a low level, and controls the PWM-2 pin of the microprocessor IC2 to output a positive pulse of the PWM value. At this time, the 1st pin of the stepless two-color light-emitting diode (12) is approximately 0V, the 2nd pin of the stepless two-color light-emitting diode (12) is the positive pulse voltage of the PWM value, the red light-emitting tube of the stepless two-color light-emitting diode (12) does not emit light, and the green light-emitting tube of the stepless two-color light-emitting diode (12) for displaying the drifting target emits light according to the duty cycle (PWM value) of the positive pulse voltage; therefore, the brightness of the green light-emitting tube of the stepless two-color light-emitting diode (12) is controlled by the microprocessor IC2, and the green light-emitting tube illuminates the drifting tail and drifting target (15) through the optical fiber drifting tail (14), thereby realizing the function of setting the brightness; S5, the microprocessor IC2 repeats steps S2-S4. When the voltage of the micro battery (5) slowly decreases, the microprocessor IC2 increases the duty cycle (PWM value) of the positive pulse voltage at pin 2 of the electrodeless two-color light emitting diode (12) according to the preset brightness voltage value of the current brightness level and the average value of the slowly decreasing current voltage value, and increases the brightness of the green light-emitting tube of the electrodeless two-color light-emitting diode (12) according to the calculation formula, thereby realizing the function of the electronic float to keep the brightness of the light basically constant.

When an alarm is required, the processor IC2 controls the PWM-1 pin to output a positive pulse voltage and controls the PWM-2 pin to output a low level. At this time, the 1st pin of the stepless two-color light-emitting diode (12) is a positive pulse voltage, the 2nd pin is approximately 0V, the green light-emitting tube of the stepless two-color light-emitting diode (12) does not emit light, and the red light-emitting tube of the stepless two-color light-emitting diode (12) used for alarm indication emits light and the brightness is adjustable according to the duty cycle (PWM value) of the positive pulse voltage; S2. According to the different maximum instantaneous relative acceleration of the float moving up and down (after deducting 1G of gravity acceleration), the luminous state of the red light-emitting tube of the stepless two-color light-emitting diode (12) will also change accordingly; when the acceleration of the float moving up and down is very small (the maximum instantaneous relative acceleration is less than 0.05G), the red light-emitting tube of the stepless two-color light-emitting diode (12) does not emit light to avoid interference with the signal; when the acceleration of the float moving up and down is small (the maximum instantaneous relative acceleration is 0.05G-0.1G), the processor IC2 sets the duty cycle (PWM value) of the positive pulse voltage of the first foot of the stepless two-color light-emitting diode (12) to 30%, and the red light-emitting tube of the stepless two-color light-emitting diode (12) briefly emits light for about 0.1 seconds to remind the angler to concentrate. Since the red light-emitting tube emits light dimly and for a very short time, it is not The angler is affected in observing the change of the float; when the acceleration of the float moving up and down is relatively large (the maximum instantaneous relative acceleration is 0.1G-0.5G), the processor IC2 sets the duty cycle (PWM value) of the positive pulse voltage of the first foot of the stepless two-color light-emitting diode (12) to 60%, and the red light-emitting tube of the stepless two-color light-emitting diode (12) continues to emit light for about 1.5 seconds, reminding the angler to consider lifting the rod to stab the fish; when the acceleration of the float moving up and down is very large (the maximum instantaneous relative acceleration is greater than 0.5G), the processor IC2 sets the duty cycle (PWM value) of the positive pulse voltage of the first foot of the stepless two-color light-emitting diode (12) to 100%, and the red light-emitting tube of the stepless two-color light-emitting diode (12) continuously flashes for about 2 seconds at a rhythm of about 0.3 seconds and about 0.2 seconds, reminding the angler to lift the rod to stab the fish.
