Description

Technical Field

[0001] This invention relates to the field of intelligent control, and in particular to a wind-sensing telescopic sprinkler head for intelligent integrated water and fertilizer irrigation. Background Technology

[0002] Existing sprinkler heads use a lifting motor to raise and irrigate the area they cover when needed. However, because the height of the sprinkler head is fixed, it can deviate in strong winds, and the stronger the wind, the greater the deviation, resulting in insufficient coverage and requiring manual water replenishment. Therefore, a device is proposed that can extend and retract the sprinkler head according to the wind force. When the wind is too strong, the sprinkler head can be retracted to bring it closer to the irrigation area, reducing the impact of the wind. When the wind is weak, the sprinkler head can be raised to irrigate a larger area. Summary of the Invention

[0015] To more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings used in the prior art and embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0016] Figure 1 , Figure 2 , Figure 3 This invention provides a schematic diagram of the wind power adjustment module structure for a wind-sensing telescopic sprinkler head used in intelligent integrated water and fertilizer irrigation. Detailed Implementation

[0017] To make the objectives and advantages of the present invention clearer, the present invention will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or more specific embodiments of the present invention and does not strictly limit the scope of protection specifically claimed by the present invention.

[0018] Referring to the accompanying drawings, this invention is a wind-powered telescopic sprinkler head for intelligent integrated water and fertilizer irrigation, including a sprinkler head, a water supply pipe, a time relay, and a lifting motor. The lifting motor is used to control the raising and lowering of the telescopic sprinkler head, and the time relay is used to set the sprinkler head start time period. It also includes a wind power adjustment module and an adjustment mechanism. The wind power adjustment module and the adjustment mechanism are connected. The wind power adjustment module is used to convert wind power signals into electrical signals and send them to the adjustment mechanism. The adjustment mechanism is used to adjust the length of the sprinkler head.

[0019] Specifically, the wind power adjustment module includes a first operational amplifier U1, a second photodiode U2, a first thermistor R1, a second resistor R2, and a first variable capacitor C1. The inverting terminal of the first operational amplifier U1 is connected to one end of the first thermistor R1 and one end of the first variable capacitor C1. The other end of the first thermistor R1 is connected to one end of the second resistor R2. The output terminal of the first operational amplifier U1 is connected to the anode of the second photodiode U2. The cathode of the second photodiode U2 is connected to the adjustment mechanism. The other end of the first variable capacitor C1 is connected to the ground terminal.

[0020] The first thermistor R1 and the second resistor R2 are connected in series, with the other end of the second resistor R2 connected to a power supply. The first thermistor R1 is used to collect air temperature and humidity signals. Changes in wind speed will change the air temperature and humidity. The higher the wind speed, the stronger the wind force. The resistance of the first thermistor R1 will change with the wind force, converting the wind force signal into an electrical signal and feeding it back to the first variable capacitor C1 and the inverting input of the first operational amplifier U1. The non-inverting input of the first operational amplifier U1 sets the wind force signal threshold voltage. When there is a signal output at the output of the first operational amplifier U1, the second photodiode U2 is turned on, and the signal is fed back to the adjustment mechanism through the second photodiode U2. After receiving the signal, the adjustment mechanism will adjust upward or downward. When there is no signal output at the output of the first operational amplifier U1, the opposite is true. At this time, the first variable capacitor C1 acts as a sensitivity adjustment capacitor. Adjusting the capacitance of the first variable capacitor C1 can change the wind force level.

[0021] Specifically, the wind power regulation module further includes a third operational amplifier U3, a fourth operational amplifier U4, a third resistor R3, a fourth resistor R4, a fifth resistor R5, a sixth resistor R6, a seventh resistor R7, a twenty-first resistor R21, a second capacitor C2, a first inductor L1, a first diode D1, a second diode D2, a third diode D3, a first PMOS transistor Q1, a second NMOS transistor Q2, a third transistor Q3, a fourth transistor Q4, a fifth NMOS transistor Q5, a sixth transistor Q6, and a seventh transistor Q7. The non-inverting input of the third operational amplifier U3 and the first operational amplifier... The inverting input of amplifier U1 is connected to the output of the third operational amplifier U3, and the gate of the second NMOS transistor Q2 is connected to the output of the third operational amplifier U3. The source of the second NMOS transistor Q2 is connected to one end of the third resistor R3, one end of the fourth resistor R4, the anode of the first diode D1, and the collector of the third NMOS transistor Q3. The cathode of the first diode D1 is connected to the non-inverting input of the fourth operational amplifier U4 and one end of the fifth resistor R5. The inverting input of the fourth operational amplifier U4 is connected to the power supply. The output of the fourth operational amplifier U4 is connected to the gate of the first PMOS transistor Q1. The source of the first PMOS transistor Q1 is connected to one end of the first inductor L1 and the anode of the third diode D3. One end of inductor L1 is connected to the power supply. The cathode of the third diode D3, one end of the second capacitor C2, and the anode of the second photodiode U2 are connected. The other end of the third resistor R3 is connected to the power supply. One end of the sixth resistor R6 is connected to the power supply. The other end of the sixth resistor R6 is connected to one end of the seventh resistor R7. The collector of the fourth transistor Q4, the anode of the second diode D2, and the source of the fifth NMOS transistor Q5 are connected. The drain of the fifth NMOS transistor Q5 and the drain of the second NMOS transistor Q2 are connected to the power supply. The gate of the fifth NMOS transistor Q5 is connected to the output of the first operational amplifier U1. The other end of the seventh resistor R7 is connected to the base of the third transistor Q3. Connect the other end of the fourth resistor R4 to the base of the fourth transistor Q4; connect the cathode of the second diode D2 to the base of the sixth transistor Q6; connect the collector of the sixth transistor Q6 to the base of the seventh transistor Q7; connect the emitter of the seventh transistor Q7 to the power supply; connect the collector of the seventh transistor Q7 to one end of the second resistor R2; connect the other end of the fifth resistor R5, the emitter of the third transistor Q3, the emitter of the fourth transistor Q4, the emitter of the sixth transistor Q6, one end of the twenty-first resistor R21, and one end of the second capacitor C2; connect the other end of the second capacitor C2, the other end of the twenty-first resistor R21, and the ground terminal.

[0022] Considering that even when the wind force meets the standard, but the wind frequency is too low, the regulating mechanism will repeatedly receive adjustment signals to change the nozzle length. This is addressed by converting the wind frequency signal into an electrical signal for output. The voltage is boosted according to the wind frequency signal frequency. When the voltage reaches the threshold of the second photodiode U2, it can conduct, feeding the signal back to the regulating mechanism to solve the aforementioned problem. It should be noted that this solution requires connecting the other end of the second resistor R2 to the ground terminal, and the connection point between the second resistor R2 and the first thermistor R1 to the collector of the seventh transistor Q7. The implementation process involves simultaneously feeding the signal from the first thermistor R1 to the non-inverting input of the third operational amplifier U3. The inverting input of the third operational amplifier U4 is set with a high-level wind force signal threshold, while the non-inverting input is set with a low-level wind force threshold signal. This creates a feedback interval for the wind force signal between the first operational amplifier U1 and the third operational amplifier U3. The inverting input of the fourth operational amplifier U4 is set with a base voltage signal, which is lower than the on-state potential of the first diode D1 but higher than its off-state potential. When the wind force is low, the output signal of the first operational amplifier U1 turns on the fifth NMOS transistor Q5. The power signal from the fifth NMOS transistor Q5 then passes through the second diode D2 to turn on the sixth transistor Q6. The power signal from the seventh transistor Q7 then passes through the seventh transistor. The base of transistor Q7, the sixth transistor Q6, and the ground terminal form a loop. The emitter signal of the seventh transistor Q7 can be fed back to the first variable capacitor C1 and the inverting input of the first operational amplifier U1 via the collector of the seventh transistor Q7 and the first thermistor R1. When the first operational amplifier U1 stops outputting, the conduction potential of the second diode D2 is lower than that of the third transistor Q3 and the fourth transistor Q4. The base power supply signal loop of the sixth transistor Q6 is powered by the power signal at the sixth resistor R6 and the second diode D2 to the base of the sixth transistor Q6. When the potential of the first variable capacitor C1 continues to rise, the output signal of the third operational amplifier U3 causes the second NMOS transistor to... When Q2 is turned on, the power signal at the second NMOS transistor Q2 reaches the fourth operational amplifier U4 through the first diode D1, and the other path reaches the fourth transistor Q4 through the fourth resistor R4. At this time, the power signal at the sixth resistor R6 forms a loop through the ground terminal of the fourth transistor Q4. The second diode D2 and the sixth transistor Q6 are turned off. When the third operational amplifier U3 has no output, the conduction potential of the first diode D1 is lower than the potentials of the third transistor Q3 and the fourth transistor Q4 due to the fourth resistor R4. The power signal at the third resistor R3 is fed back to the non-inverting input of the fourth operational amplifier U4 through the third resistor R3 and the first diode D1. The fifth resistor R5 is used for signal pull-up.In other words, when the wind force level meets the standard and the wind frequency is high, the first step is to output a signal from the third operational amplifier U3 to turn on the second NMOS transistor Q2. The power signal from the second NMOS transistor Q2 reaches the non-inverting input of the fourth operational amplifier U4 through the first diode D1. The fourth operational amplifier U4 will output a signal to turn on the first PMOS transistor Q1, and vice versa. When the first PMOS transistor Q1 is off, the power signal from the first inductor L1 powers the second capacitor C2 through the third diode D3. When the first PMOS transistor Q1 is on, the first inductor L1 forms a loop through the first PMOS transistor Q1 to the ground terminal, and the second capacitor C2 powers the second photodiode U2. After the first PMOS transistor Q1 turns on again, the power supply voltage of the second capacitor C2 and the power supply voltage of the first inductor L1 are superimposed to complete the voltage boost. However, if the wind frequency is too high, the fourth operational amplifier U4 will repeatedly output a signal to turn on and off the first PMOS transistor Q1, and the final boost amplitude will reach the conduction threshold of the second photodiode U2. Conversely, when the wind frequency is low, the second capacitor C2 will turn on and off. 2. The discharge rate through the twenty-first resistor R21 is higher than the voltage boost rate, thus adjusting the output signal of the regulating mechanism when both high-level wind force and wind frequency meet the standard. At this time, the first variable capacitor C1 acts as a wind frequency sensitivity adjustment capacitor. When the first operational amplifier U1 and the third operational amplifier U3 have no output, the first variable capacitor C1 forms a loop through the first thermistor R1, the second resistor R2, and the ground terminal. The wind force level is provided by the wind force signal feedback range composed of the first operational amplifier U1 and the third operational amplifier U3. That is, when the wind frequency is too high and it is a high-level wind force, the signal is fed back to the first variable capacitor C1 through the first thermistor R1, and the potential of the first variable capacitor C1 continuously rises, eventually causing the third operational amplifier U3 to output. Conversely, when the wind force level is too low, regardless of the wind frequency, the potential at the end of the first variable capacitor C1 is always lower than the potential at the inverting end of the third operational amplifier U3, and the third operational amplifier U3 has no output, thus filtering out excessively high wind frequencies at low wind force levels.

[0023] Specifically, the wind power adjustment module also includes a multi-level output circuit, which includes a first connection terminal P1, an eighth resistor R8, a first light-emitting diode LED1, and a second output terminal OUT2. One end of the first connection terminal P1 is connected to the cathode of the third diode D3, the other end of the first connection terminal P1 is connected to one end of the eighth resistor R8, the other end of the eighth resistor R8 is connected to the anode of the first light-emitting diode LED1, and the cathode of the first light-emitting diode LED1 is connected to the second output terminal OUT2.

[0024] Considering that multiple gear adjustments can increase the range of use, the first connection terminal P1 is connected to the multi-gear output circuit. The principle is that the eighth resistor R8 and the first light-emitting diode LED1 are connected in series to make the eighth resistor R8 first drop the voltage. When the boost value of the current stage circuit is higher than the conduction threshold of the first light-emitting diode LED1, the first light-emitting diode LED1 conducts and outputs a signal to the second output terminal OUT2. The second output terminal OUT2 is connected to the adjustment mechanism.

[0025] Specifically, the wind power adjustment module also includes a ninth resistor R9, a tenth resistor R10, an eleventh resistor R11, a twelfth resistor R12, a thirteenth resistor R13, and a fourteenth resistor R14.

The other end of the thirteenth resistor R13 is connected to one end of the fourteenth resistor R14 and the non-inverting input of the first operational amplifier U1. The other end of the fourteenth resistor R14 is connected to the ground terminal.

[0026] Considering power supply stability, the voltage divider of the ninth resistor R9, tenth resistor R10, and eleventh resistor R11 provides the wind power signal threshold voltage to the inverting input of the third operational amplifier U3, and the voltage divider of the twelfth resistor R12, thirteenth resistor R13, and fourteenth resistor R14 provides the wind power signal threshold voltage to the non-inverting input of the first operational amplifier U1. At the same time, the connection terminals of the twelfth resistor R12 and the thirteenth resistor R13 are connected to the drains of the second NMOS transistor Q2 and the fifth NMOS transistor Q5, which can reduce the number of resistors used.

[0028] The purpose of setting the fifteenth resistor R15, the sixteenth resistor R16, and the seventeenth resistor R17 is to discharge the parasitic capacitance of the MOSFET connected to them.

[0029] Specifically, the wind power adjustment module also includes an eighteenth resistor R18, the two ends of which are connected in series between the collector of the sixth transistor Q6 and the base of the seventh transistor Q7;

[0032] By coupling the second photodiode U2 and the fifth phototransistor U5, the signal output of the first output terminal OUT1 can be amplified, while isolating and reducing signal interference.

[0033] Specifically, the multi-level output circuit also includes a nineteenth resistor R19, a twentieth resistor R20, a second light-emitting diode LED2, a third light-emitting diode LED3, a third output terminal OUT3, and a fourth output terminal OUT4. One end of the nineteenth resistor R19 is connected to one end of the eighth resistor R8, the other end of the nineteenth resistor R19 is connected to the anode of the second light-emitting diode LED2 and the twentieth resistor R20, the cathode of the second light-emitting diode LED2 is connected to the third output terminal OUT3, the other end of the twentieth resistor R20 is connected to the anode of the third light-emitting diode LED3, and the cathode of LED3 is connected to the fourth output terminal OUT4.

[0034] The number of adjustable levels can be increased by using the nineteenth resistor R19, LED, the twentieth resistor R20, and the third LED3. When signal isolation is required, the first LED1, the second LED2, and the third LED3 can be replaced with phototransistors.
