Description

Technical Field

[0001] This invention relates to the field of automatic control technology for vibrators, and more particularly to an automatic control system for a vibrator used in a fishpond feeder. Background Technology

[0002] In fish and shrimp farming, farmers need to install feeders next to the fishponds to feed the fish and shrimp. The feeder typically needs to evenly transport feed from the storage bin or hopper to the feeding port. Since feed particles may accumulate or clog due to friction, stillness, or other factors, a vibrator can loosen the feed and maintain its fluidity through high-frequency vibration, preventing clogging. Specifically, the feeding speed is controlled by adjusting the amplitude of the vibrator.

[0003] Currently available vibrators require manual adjustment of their amplitude via a knob. During peak daytime usage, when the power supply voltage is low, the vibration amplitude decreases significantly, leading to insufficient feed and affecting the growth of fish and shrimp. Conversely, during off-peak nighttime usage, the power supply voltage is high, causing the vibration amplitude to increase significantly, resulting in abnormal vibration, feed waste, and even vibrator damage. In all these situations, manual adjustment of the vibration amplitude via the knob is necessary, requiring regular inspections, which wastes manpower. Inattentive inspections may also damage the vibrator, lead to feed waste, or cause nutritional deficiencies in fish and shrimp.

[0004] Therefore, there is an urgent need to provide an automatic control system for the vibrator of a fishpond feeder, which can improve the feeding accuracy and uniformity compared to existing technologies. Summary of the Invention

[0005] The purpose of this invention is to provide:

[0006] An automatic control system for a vibrator in a fishpond feeder, and related technologies, to solve technical problems such as how to improve feeding accuracy and uniformity, or a combination thereof.

[0016] The term "decibel" as used in this article refers to the measure of sound intensity.

[0017] This invention provides an automatic control system for a vibrator of a fishpond feeder: It includes an MCU module, an accelerometer, a vibrator control circuit, a microphone, a power supply circuit, and a voltage acquisition circuit. The accelerometer, the vibrator control circuit, the microphone, the power supply circuit, and the voltage acquisition circuit are respectively connected to different interfaces of the MCU module. The power supply circuit provides input voltage to the vibrator. The vibrator control circuit works in conjunction with the power supply circuit to control the vibration intensity of the vibrator. The voltage acquisition circuit acquires the input voltage value of the vibrator. The accelerometer detects the acceleration value of the vibrator. The microphone acquires the sound signal emitted by the vibrator, where the sound signal is a decibel value. The MCU module is used to adjust the vibration intensity of the vibrator based on the detected input voltage value, acceleration value, decibel value, the conduction time of the vibrator control circuit, and / or the input voltage value of the power supply circuit.

[0018] The vibrator control circuit is connected to the MCU module through the GPIO port, controls the transistor Q1 to conduct, the transistor Q1 controls the optocoupler E1 to conduct, the optocoupler E1 controls the conduction time of the thyristor D1, and the vibration intensity of the vibrator is adjusted by controlling the conduction time of the thyristor D1.

[0019] The voltage acquisition circuit isolates the voltage signal through the current transformer PT1, rectifies it through thyristors D3, D4, D5, and D6, and filters it through capacitors C12 and C13 to convert it into a DC voltage signal. This DC voltage signal is then sent to the ADC acquisition interface of the MCU module. The MCU module performs AD conversion on the DC voltage signal to convert it into the input voltage value of the vibrator.

[0020] The accelerometer communicates with the MCU module via an I2C interface. The MCU module reads and writes the accelerometer register values ​​via I2C communication to set and read the acceleration status of the XYZ axes and obtain the acceleration value of the vibrator.

[0021] The MCU module is configured with a normal acceleration range, which is represented as [minimum acceleration value, maximum acceleration value]. The minimum acceleration value is preferably -6g, and the maximum acceleration value is preferably 6g, where g represents gravitational acceleration. When the acceleration value detected by the accelerometer is greater than the maximum acceleration value, the power supply circuit is adjusted to lower the input voltage value provided to the vibrator, and / or the vibrator control circuit is adjusted to shorten the conduction time of the thyristor D1. When the acceleration value detected by the accelerometer is less than the minimum acceleration value, the power supply circuit is adjusted to increase the input voltage value provided to the vibrator, and / or the vibrator control circuit is adjusted to lengthen the conduction time of the thyristor D1.

[0022] During the acceleration adjustment process, the MCU module stops adjusting the power supply voltage and / or the vibrator control circuit until the acceleration value detected by the accelerometer is within the normal acceleration range. When the adjustment time reaches the set time, it indicates that the vibrator is faulty or the power supply voltage is abnormal.

[0023] The analog voltage signal generated by microphone MIC1 is sent to the ADC acquisition interface of the MCU module. The MCU module performs AD analog-to-digital conversion and converts it into decibels.

[0024] The MCU module sets the decibel normal range, which is represented as: [minimum decibel value, maximum decibel value]. When the decibel value of the sound signal detected by the microphone is greater than the maximum decibel value, the MCU module controls the vibrator control circuit to shorten the conduction time of the thyristor D1 and reduce the vibration intensity of the vibrator. When the decibel value of the sound signal detected by the microphone is less than the minimum decibel value, the MCU module controls the vibrator control circuit to lengthen the conduction time of the thyristor D1 and increase the vibration intensity of the vibrator.

[0025] The MCU module acquires the input voltage value of the vibrator from the voltage acquisition circuit and sets the normal voltage range, represented as: [minimum voltage value, maximum voltage value]. When the power supply voltage is high at night and the input voltage value of the vibrator is greater than the maximum voltage value, the MCU module controls the vibrator control circuit to shorten the conduction time of the thyristor D1 and reduce the vibration intensity of the vibrator. When the power supply voltage is low during the day and the input voltage value of the vibrator is less than the minimum voltage value, the MCU module controls the vibrator control circuit to lengthen the conduction time of the thyristor D1 and increase the vibration intensity of the vibrator.

[0026] The vibrator includes an electromagnet, a vibrating plate, an iron plate, and an elastic steel plate. The upper end of the elastic steel plate is fixedly connected to the vibrating plate, and the lower wall of the vibrating plate is fixedly connected to the iron plate. The electromagnet is disposed inside the elastic steel plate and is positioned corresponding to the iron plate. When the electromagnet is energized, it acts on the iron plate, causing the vibrating plate to vibrate. The vibrating plate is equipped with an accelerometer and a microphone.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention monitors the acceleration value, decibel value of the generated sound, and input voltage value of the vibrator to determine abnormal conditions. It can comprehensively consider the possible abnormalities of the vibrator, thereby identifying the cause of the abnormality and making corresponding adjustments to restore the vibrator to normal operation, thus improving the feeding accuracy and uniformity.

[0037] The technical solution of the present invention will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are not all embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention. It should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0038] like Figure 1 As shown, this invention provides an automatic control system for a vibrator in a fishpond feeder, including an MCU module, an accelerometer, a vibrator control circuit, a microphone, a power supply circuit, and a voltage acquisition circuit. The MCU is a microcontroller unit. The accelerometer, vibrator control circuit, microphone, power supply circuit, and voltage acquisition circuit are connected to different interfaces of the MCU module. The power supply circuit provides input voltage to the vibrator. The vibrator control circuit and power supply circuit work together to control the vibration intensity of the vibrator. The voltage acquisition circuit collects the real-time voltage of the vibrator. The accelerometer uses an accelerometer sensor to detect the real-time acceleration value of the vibrator. The microphone collects the sound signal emitted by the vibrator. The MCU module adjusts the vibration intensity of the vibrator based on the voltage, acceleration value, and sound signal, through the vibrator control circuit and / or power supply circuit. This maintains stable vibration intensity, ensuring feeding accuracy and uniformity.

[0039] like Figure 2As shown, the vibrator of the fishpond feeder includes an electromagnet 1, a vibrating plate 2, an iron plate 3, and an elastic steel plate 4. The upper end of the elastic steel plate 4 is fixedly connected to the vibrating plate 2, and the lower wall of the vibrating plate 2 is fixedly connected to the iron plate 3. An electromagnet 1 is installed inside the elastic steel plate 4, and the electromagnet 1 is positioned corresponding to the iron plate 3. When the electromagnet 1 is energized, it attracts the iron plate 3 at a certain frequency. The iron plate 3 is fixed on the vibrating plate 2, thereby causing the vibrating plate 2 to vibrate at a certain frequency and amplitude. An accelerometer and a microphone are installed on the vibrating plate 2.

[0040] The circuit of the MCU module is as follows Figure 3 As shown, the power supply circuit is as follows Figure 4 As shown.

[0041] Vibrator control circuit such as Figure 5 As shown, pin 22 of the MCU module controls transistor Q1 to conduct via a GPIO port (network name: IOA10_CTRL_VIBRATOR). Transistor Q1 controls optocoupler E1 to conduct, and optocoupler E1 controls the conduction time of SCR D1. The MCU module acquires the voltage of the vibrator through a voltage acquisition circuit, such as... Figure 6 As shown, the voltage acquisition circuit isolates the voltage signal through a current transformer PT1, rectifies it through SCRs D3, D4, D5, and D6, and then filters it through capacitors C12 and C13 to convert it into a stable DC voltage signal (network name: IOC3_ADC3_VOLT). This DC voltage signal is connected to the ADC acquisition interface of the MCU module (MCU pin 29). The MCU module performs an analog-to-digital conversion on the DC voltage signal to convert it into the input voltage value of the vibrator. The vibration intensity of the vibrator is directly proportional to the input voltage value and the conduction time of SCR D1; that is, the larger the input voltage value of the vibrator, the longer the conduction time of SCR D1, and the greater the vibration intensity.

[0042] The circuit part of the accelerometer, such as Figure 7 As shown, the accelerometer communicates with the MCU module via an I2C interface at a rate of 200kHz. The MCU module reads and writes the accelerometer register values ​​via I2C to set and read the acceleration data along the XYZ axes. The network names are IOB4_SCL0 and IOA14_SDA0, corresponding to pins 35 and 36 of the MCU module. The microphone circuitry is as follows... Figure 8 As shown, the analog voltage signal (network name: IOC4_ADC4_VOICE) generated by the microphone MIC1 is connected to the ADC acquisition interface (MCU pin 28) of the MCU module. The MCU module performs AD analog-to-digital conversion and converts it into a sound signal.

[0043] The optocoupler E1 is model MOC3052S-TA1, the thyristor D1 is model BTB08-800CW, the accelerometer uses accelerometer sensor U1, model SC7A20H, the microphone MIC1 is model MIC-4013-G-G00, the power supply module U3 in the power supply circuit is model DA10-220S05G9N4, the MCU module U2 is V8520, and the current transformer PT1 is model AXPT107F-1.

[0044] The MCU module sets the normal acceleration range, which is represented as: [minimum acceleration value, maximum acceleration value]. The minimum acceleration value is preferably -6g, and the maximum acceleration value is preferably 6g, where g represents gravitational acceleration. The accelerometer operates at a voltage of 1.7~3.6V, a temperature of -40℃~85℃, and detects acceleration within a range of -16g~16g. Acceleration is directly proportional to voltage. Since the operating voltage is a sinusoidal AC current, acceleration is maximum when the voltage is at the peak or trough of the sine wave. When the acceleration value detected by the accelerometer exceeds the maximum acceleration value... When the acceleration value is below the minimum acceleration value, adjust the power supply circuit to lower the voltage supplied to the vibrator, and / or adjust the vibrator control circuit to shorten the conduction time of the thyristor D1; when the acceleration value detected by the accelerometer is less than the minimum acceleration value, adjust the power supply circuit to increase the voltage supplied to the vibrator, and / or adjust the vibrator control circuit to lengthen the conduction time of the thyristor D1; until the acceleration value detected by the accelerometer is within the normal acceleration range, stop adjusting the power supply voltage and / or the vibrator control circuit. When the adjustment time reaches the set time, it indicates that the vibrator is faulty or the power supply voltage is abnormal, and repair is required.

[0045] The MCU module sets the decibel normal range, which is represented as: [minimum decibel value, maximum decibel value]. The minimum decibel value is preferably 60dB, and the maximum decibel value is preferably 90dB. When the decibel value of the sound signal detected by the microphone is greater than 90dB, the MCU module controls the vibrator control circuit to shorten the conduction time of the thyristor D1 and reduce the vibration intensity of the vibrator. When the decibel value of the sound signal detected by the microphone is less than 60dB, the MCU module controls the vibrator control circuit to lengthen the conduction time of the thyristor D1 and increase the vibration intensity of the vibrator.

[0046] The MCU module acquires the voltage value of the vibrator from the voltage acquisition circuit and sets the normal voltage range, represented as: [minimum voltage value, maximum voltage value]. When the power supply voltage is high at night, and the voltage value of the vibrator acquired by the voltage acquisition circuit is greater than the maximum voltage value, the MCU module controls the vibrator control circuit to shorten the conduction time of the thyristor D1 and reduce the vibration intensity of the vibrator. When the power supply voltage is low during the day, and the voltage value of the vibrator acquired by the voltage acquisition circuit is less than the minimum voltage value, the MCU module controls the vibrator control circuit to lengthen the conduction time of the thyristor D1 and increase the vibration intensity of the vibrator.

[0047] This invention primarily uses accelerometer-detected acceleration values ​​to determine the normality of vibrator vibration intensity. Microphone-detected decibel values ​​serve as an auxiliary indicator, mainly used to identify abnormal vibrations, such as an electromagnet striking an iron plate. Voltage detection is used to analyze the causes of excessively high or low vibration intensity for easier control. If the acceleration value is within the range of -6g to 6g, but the sound exceeds 90dB, the vibrator is considered malfunctioning, and the vibration intensity should be reduced immediately. If the sound cannot be reduced below 90dB, the vibrator should be stopped, and the user should inspect it. If the operating voltage is lower than the rated voltage, the vibration intensity should be increased. If the acceleration cannot be maintained within the normal range, operation should be stopped, and the user should check the power supply line for abnormalities. If the operating voltage is 30% higher than the rated operating voltage, to protect the vibrator, operation should be stopped immediately, and the vibrator should be restarted only after the voltage returns to normal.

[0048] This invention monitors the acceleration value, decibel value of the generated sound, and input voltage value of the vibrator to determine abnormal conditions. It can comprehensively consider the possible abnormalities of the vibrator, thereby identifying the cause of the abnormality and making corresponding adjustments to restore the vibrator to normal operation, thus improving the feeding accuracy and uniformity.

[0049] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, and is not intended to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention do not depart from the essence and scope of the technical solution of the present invention.
