[0044] The first delay module is connected to the bistable module and is used to control the working state of the bistable module to flip from the first working state to the second working state when the duration of the water pump spray module in the working state reaches the first duration threshold, so that the drive module controls the water pump spray module to be in the non-working state.

[0046] According to some embodiments, the first and second duration thresholds are not specifically fixed thresholds. These thresholds can be set according to the actual application scenario.

[0049] The first input terminal of the rectifier circuit is connected to the second terminal of the step-down circuit, and the second input terminal of the rectifier circuit is connected to the second terminal of the AC power supply.

[0051] The input terminal of the voltage regulator and filter circuit is connected to the positive output terminal of the rectifier circuit. The positive output terminal of the voltage regulator and filter circuit is connected to the bistable module, the first delay module, and the second delay module, respectively. The negative output terminal of the voltage regulator and filter circuit and the negative output terminal of the rectifier circuit are grounded. The voltage regulator and filter circuit is used to regulate and filter the first DC voltage to obtain and provide a second DC voltage for the bistable module, the first delay module, and the second delay module.

[0052] According to some embodiments, the AC power supply does not specifically refer to a particular fixed power source. For example, the AC power supply can be an AC power supply that outputs 220V AC voltage; the AC power supply can also be an AC power supply that outputs 380V AC voltage.

[0053] In some embodiments, Figure 2 This is a schematic diagram of a waste mine restoration system provided in an embodiment of this disclosure. Figure 2 As shown, the trigger circuit includes a second switch K2. The first end of the second switch K2 is connected to the first output end of the AC power supply, and the second end of the second switch K2 is connected to the first end of the drive module and the first end of the step-down circuit, respectively.

[0055] The connection point between the first terminal of the twelfth resistor R12 and the first terminal of the fourth capacitor C4 is the first terminal of the step-down circuit, and the connection point between the second terminal of the twelfth resistor R12 and the second terminal of the fourth capacitor C4 is the second terminal of the step-down circuit.

[0056] In some embodiments, the fourth capacitor C4 is used to store the first AC voltage input from the AC power supply, thereby achieving a voltage reduction effect. The fourth capacitor C4 is a non-polarized capacitor, and its capacitance value can be, for example, 0.41uF.

[0057] In some embodiments, the twelfth resistor R12 is used to prevent the release of electrical energy stored in the fourth capacitor C4 due to a disconnection of the subsequent circuit. The resistance value of the twelfth resistor R12 can be, for example, 1 MΩ.

[0058] According to some embodiments, the rectifier circuit may be, for example, a bridge rectifier circuit consisting of four diodes.

[0059] According to some embodiments, the voltage stabilizing and filtering circuit includes a voltage stabilizing circuit and a filtering circuit; wherein, the voltage stabilizing circuit is used to stabilize the first DC voltage input to the rectifier circuit at a second DC voltage, and the filtering circuit is used to filter the second DC voltage, thereby suppressing electromagnetic noise and improving the anti-interference capability of the system.

[0060] In some embodiments, such as Figure 2 As shown, the voltage regulator circuit includes a thirteenth resistor R13, a fourteenth resistor R14, a first diode D1, and a second diode D2; the filter circuit includes a fifth capacitor C5; wherein,

[0061] The connection point between the first end of the thirteenth resistor R13 and the first end of the fourteenth resistor R14 is the input terminal of the voltage regulator filter circuit. The second end of the fourteenth resistor R14 is connected to the positive terminal of the first diode D1. The negative terminal of the first diode D1, the positive terminal of the second diode D2, and the negative terminal of the fifth capacitor C5 are grounded. The connection point between the second end of the thirteenth resistor R13, the negative terminal of the second diode D2, and the positive terminal of the fifth capacitor C5 is the positive output terminal of the voltage regulator filter circuit.

[0062] In some embodiments, the second diode D2 is a Zener diode, also known as a Zener diode. This type of diode utilizes the reverse breakdown state of a PN junction and the phenomenon that the voltage remains essentially constant while the current can vary over a wide range. This Zener diode is a semiconductor device with very high resistance up to the critical reverse breakdown voltage. At this critical breakdown point, the reverse resistance drops to a very small value, and in this low-resistance region, the current increases while the voltage remains constant.

[0063] For example, when the resistance of the thirteenth resistor R13 is 3.6K ohms and the second diode D2 is a 2CW10, the first DC voltage can be regulated to a second DC voltage of 12V through the thirteenth resistor R13 and the second diode D2.

The remote drive module is used to control the on / off state of the trigger circuit.

[0070] According to some embodiments, such as Figure 2 As shown, the output terminal of the remote drive module is connected to the control terminal of the second switch K2. Therefore, the on / off state of the second switch K2 can be remotely controlled via a terminal device, such as a mobile phone or computer, thereby realizing remote power on / off functionality, which can improve system efficiency and the convenience and flexibility of system use.

[0071] Alternatively, in one embodiment of this disclosure, such as Figure 2 As shown, the bistable module includes a first relay, a first transistor Q1, a second transistor Q2, a dual-base diode Q3, a first resistor R1, a second resistor R2, a third resistor R3, a fourth resistor R4, and a fifth resistor R5. The first relay includes a first relay coil J1, a first relay switch J1-1, a second relay switch J1-2, a third relay switch J1-3, and a fourth relay switch J1-4; wherein,

[0072] The connection point between the first end of the first resistor R1, the first end of the second resistor R2, and the first end of the first relay coil J1 is connected to the positive output terminal of the voltage regulator filter circuit. The second end of the first resistor R1 is connected to the first end of the third resistor R3 and the collector of the first transistor Q1. The second end of the third resistor R3 is connected to the base of the second transistor Q2 and the first moving contact of the first relay switch J1-1. The base of the first transistor Q1 is connected to the first end of the fourth resistor R4 and the second moving contact of the first relay switch J1-1. The second end of the fourth resistor R4 is connected to the second end of the first relay coil J1 and the collector of the second transistor Q2. The stationary contact of the first relay switch J1-1 is connected to the first base of the dual-base diode Q3 and the first end of the fifth resistor R5. The second base of the dual-base diode Q3 is connected to the second end of the second resistor R2. The emitters of the first transistor Q1, the emitters of the second transistor Q2, and the second end of the fifth resistor R5 are grounded.

[0073] The emitter of the dual-base diode Q3 is connected to the stationary contact of the second relay switch J1-2. The first moving contact of the second relay switch J1-2 is connected to the first end of the first delay module. The second moving contact of the second relay switch J1-2 is connected to the first end of the second delay module. The stationary contact of the third relay switch J1-3 is grounded. The first moving contact of the third relay switch J1-3 is connected to the second end of the first delay module. The second moving contact of the third relay switch J1-3 is connected to the second end of the second delay module. The fourth relay switch J1-4 is connected to the drive module.

[0074] According to some embodiments, when the second switch K2 is closed, since the second moving contact of the first relay switch J1-1 is a normally closed contact, the base of the second transistor Q2 can be grounded through the first relay switch J1-1. As a result, the second transistor Q2 will be in the off state, the first transistor Q1 will be in the on state, and the current flowing through the first relay coil J1 will be lower than the current threshold. That is to say, the first relay will be in the non-working state, and the bistable module will be in the first working state.

[0075] In some embodiments, when the first relay is in a non-operating state, the second moving contact of the first relay switch J1-1 is connected to the stationary contact of the first relay switch J1-1, the first moving contact of the second relay switch J1-2 is connected to the stationary contact of the second relay switch J1-2, the second moving contact of the third relay switch J1-3 is connected to the stationary contact of the third relay switch J1-3, and the fourth relay switch J1-4 is in a closed state.

[0078] Alternatively, in one embodiment of this disclosure, such as Figure 3 As shown, the first delay module includes a first potentiometer W1, a sixth resistor R6, a seventh resistor R7, an eighth resistor R8, and a first capacitor C1; wherein,

[0079] The first terminal of the first potentiometer W1 is connected to the positive output terminal of the voltage regulator filter circuit. The second terminal of the first potentiometer W1 is connected to the first terminal of the sixth resistor R6. The second terminal of the sixth resistor R6 is connected to the first terminal of the seventh resistor R7. The connection point between the second terminal of the seventh resistor R7, the first terminal of the eighth resistor R8, and the positive terminal of the first capacitor C1 is connected to the first moving contact of the second relay switch J1-2. The negative terminal of the first capacitor C1 is grounded. The second terminal of the eighth resistor R8 is connected to the first moving contact of the third relay switch J1-3.

[0080] According to some embodiments, when the first relay coil J1 is in a non-operating state, the positive output terminal of the voltage regulator filter circuit can charge the first capacitor C1. Therefore, the first charging voltage at the connection point between the second terminal of the seventh resistor R7, the first terminal of the eighth resistor R8, and the positive terminal of the first capacitor C1 gradually increases. When this first charging voltage is greater than the peak point voltage of the bipolar diode Q3, since the first moving contact of the second relay switch J1-2 is connected to the stationary contact of the second relay switch J1-2, the bipolar diode Q3 will output a positive pulse signal, causing the second transistor Q2 to switch from the cutoff state to the conduction state, and the first transistor Q1 to switch from the conduction state to the cutoff state. The current flowing through the first relay coil J1 will not be lower than the current threshold, that is, the first relay will be in an operating state, and the bistable module will switch from the first operating state to the second operating state.

[0081] In some embodiments, when the first relay is in the working state, the first moving contact of the first relay switch J1-1 is connected to the stationary contact of the first relay switch J1-1, the second moving contact of the second relay switch J1-2 is connected to the stationary contact of the second relay switch J1-2, the first moving contact of the third relay switch J1-3 is connected to the stationary contact of the third relay switch J1-3, and the fourth relay switch J1-4 is in the open state.

[0082] At this time, since the first moving contact of the third relay switch J1-3 is connected to the stationary contact of the third relay switch J1-3, the charge stored in the first capacitor C1 can be released through the eighth resistor R8 to ensure the accuracy of the next charging time.

[0083] According to some embodiments, the resistance of the first potentiometer W1 can be, for example, 50K ohms; the resistance of the sixth resistor R6 can be, for example, 160K ohms; the resistance of the seventh resistor R7 can be, for example, 68K ohms; the resistance of the eighth resistor R8 can be, for example, 10 ohms; and the capacitance of the first capacitor C1 can be, for example, 47uF.

[0085] The first terminal of the second potentiometer W2 is connected to the positive output terminal of the voltage regulator filter circuit. The second terminal of the second potentiometer W2 is connected to the first terminal of the ninth resistor R9. The connection point between the second terminal of the ninth resistor R9 and the first terminal of the tenth resistor R10, and the positive terminal of the second capacitor C2, is connected to the second moving contact of the second relay switch J1-2. The negative terminal of the second capacitor C2 is grounded. The second terminal of the tenth resistor R10 is connected to the second moving contact of the third relay switch J1-3.

[0086] According to some embodiments, the positive output terminal of the voltage regulator filter circuit can charge the second capacitor C2. Therefore, the second charging voltage at the connection point between the second terminal of the ninth resistor R9, the first terminal of the tenth resistor R10, and the positive terminal of the second capacitor C2 gradually increases. When this second charging voltage is greater than the peak voltage of the bipolar diode Q3, since the second moving contact of the second relay switch J1-2 is connected to the stationary contact of the second relay switch J1-2, the bipolar diode Q3 will output a positive pulse signal again, causing the second transistor Q2 to switch from the on state to the off state, and the first transistor Q1 to switch from the off state to the on state. The current flowing through the first relay coil J1 will be lower than the current threshold, that is, the first relay will be in a non-operating state, and the bistable module will switch from the second operating state to the first operating state.

[0087] According to some embodiments, the resistance of the second potentiometer W2 can be, for example, 2.2M ohms; the resistance of the ninth resistor R9 can be, for example, 560K ohms; the resistance of the tenth resistor R10 can be, for example, 10 ohms; and the capacitance of the second capacitor C2 can be, for example, 470uF.

[0088] Alternatively, in one embodiment of this disclosure, such as Figure 2 As shown, the drive module includes a second relay, an eleventh resistor R11, a third capacitor C3, and a first switch K1. The second relay includes a second relay coil J2 and a fifth relay switch; wherein,

The fifth relay switch is connected to the water pump spray module.

[0090] According to some embodiments, when the fourth relay switch J1-4 is in the closed state, the second relay coil J2 will be in the working state due to being energized, thereby causing the fifth relay switch to be in the closed state, so that the water pump spray module is in the working state.

[0095] The motor is connected to the water pump via the fifth relay switch. The motor is used to control the working status of the water pump so that the water pump delivers water to the water inlet and nutrient solution filling module.

[0096] According to some embodiments, Figure 3 This is a schematic diagram of the structure of a water pump spray module provided in an embodiment of this disclosure. Figure 3 As shown, the water inlet and nutrient solution filling module includes a water pump inlet, a control valve, a nutrient solution storage tank, a sampling valve, a proportioning mixer, a liquid outlet valve, a water inlet control valve, and a water flow indicator; among which,
