[0039] In modern agricultural production, greenhouses provide a stable growing environment for crops. However, this stable environment is often accompanied by the proliferation of pests and diseases. In practical applications, pest control and irrigation of crops in traditional greenhouses require significant labor costs. These problems not only affect the healthy growth of crops but also exacerbate the economic pressure on agricultural production. Therefore, this paper proposes a solution to address these technical issues.
[0040] In response, this specification provides a greenhouse control system, which will be described in detail in the following embodiments.
[0041] See Figure 1 , Figure 1 This is a schematic diagram of the overall structure of a greenhouse pest control system provided in one embodiment of this specification, including: a temperature monitoring device 1, a humidity monitoring device 2, a pest monitoring device 3, a first driving device 41, a second driving device 42, a third driving device 43, a first liquid storage device 5, a second liquid storage device 6, and an irrigation device 7.
[0042] The temperature monitoring device 1, the first driving device 41, and the first liquid storage device 5 are connected in sequence. The temperature monitoring device 1 is configured to control the first driving device 41 to pump the liquid in the first liquid storage device 5 to the irrigation device 7 and spray it out when the temperature of the greenhouse is detected to be higher than a first threshold.
[0043] The humidity monitoring device 2, the second driving device 42, and the first liquid storage device 5 are connected in sequence. The humidity monitoring device 2 is configured to control the second driving device 42 to pump the liquid in the first liquid storage device 5 to the irrigation device 7 and spray it out when the humidity of the greenhouse is detected to be lower than the second threshold.
[0044] The four pests monitoring device 3, the third driving device 43, and the second liquid storage device 6 are connected in sequence. The four pests monitoring device 3 is configured to control the third driving device 43 to pump the liquid in the second liquid storage device 6 to the irrigation device 7 and spray it out when the level of pests detected in the greenhouse is higher than the third threshold.
[0045] Specifically, the temperature monitoring device 1, humidity monitoring device 2, and pest monitoring device are all installed inside the greenhouse and all have logical judgment functions. Users can pre-set parameters according to their needs, namely the first threshold, the second threshold, and the third threshold. After the parameters are set, the temperature monitoring device 1, humidity monitoring device 2, and pest monitoring device 3 will make logical judgments on the monitored data and then issue control commands to drive the corresponding drive devices to pump and spray liquid.
[0046] Among them, the temperature monitoring device 1 and the humidity monitoring device 2 can control different drive devices to pump clean water from the same first liquid storage device 5. That is, when the temperature is too high or the humidity is too low, the irrigation device 7 is controlled to spray clean water. Two drive devices are used because the demand for water in the greenhouse is high when the temperature is too high or the humidity is too low. Therefore, one drive device may not be able to meet the large water supply demand. Two drive devices are needed to work together to ensure the efficient operation of the irrigation device 7.
[0047] The pest monitoring device 3 controls an independent drive device to pump pesticide from the second liquid storage device 6. When there are too many pests in the greenhouse, it controls the irrigation device 7 to spray pesticide to meet the pest control needs.
[0048] In another embodiment of this specification, the temperature monitoring device can be replaced with a temperature and smoke monitoring device to prevent fires.
[0049] In summary, the greenhouse pest control system provided in this specification can intelligently regulate temperature and humidity, accurately control pests, and ensure efficient irrigation through the coordinated operation of multiple drive devices, thereby meeting the needs of crop growth and improving agricultural production efficiency.
[0050] See Figure 2 , Figure 2 This is a schematic diagram of the circuit connection structure of a greenhouse temperature control system according to one embodiment of this specification. Furthermore, in order to control the temperature inside the greenhouse more accurately and efficiently, the temperature monitoring device 1 includes a temperature monitoring module 11 and a first logic control circuit. The signal output terminal of the temperature monitoring module 11 is connected to the first logic control circuit. The temperature monitoring module 11 is configured to send a first control signal to the first logic control circuit when it detects that the temperature of the greenhouse is higher than a first threshold. The first logic control circuit is energized upon receiving the first control signal and controls the first drive device 41 to start.
[0051] Specifically, the temperature monitoring module 11 collects temperature data in real time through a high-precision sensor and performs logical judgment. When the judgment result meets the conditions, it sends a first control signal to the first logic control circuit. The first control signal can be understood as the internal switch of the temperature monitoring module 11 closing when the logical judgment result meets the conditions, outputting a high level to the first logic control circuit, so that the first logic control circuit is turned on, and then the first drive device 41 is started to pump the clean water in the liquid storage device to the irrigation device 7 for spraying.
[0052] In summary, the greenhouse control system provided in this specification achieves precise regulation of water spray volume through the synergistic effect of the temperature monitoring module 11 and the logic control circuit, ensuring a suitable greenhouse environment for crop growth and improving the level of agricultural automation.
[0053] Furthermore, in order to more accurately regulate the humidity inside the greenhouse, the humidity monitoring device 2 includes a humidity monitoring module 21 and a second logic control circuit; the signal output terminal of the humidity monitoring module 21 is connected to the second logic control circuit, and the humidity monitoring module 21 is configured to send a second control signal to the second logic control circuit when it detects that the humidity in the greenhouse is lower than a second threshold. The second logic control circuit is energized upon receiving the second control signal and controls the second drive device 42 to start.
[0054] Specifically, the humidity monitoring module 21 uses a high-precision sensor to collect humidity data in real time and performs logical judgment. When the judgment result meets the conditions, it sends a second control signal to the second logic control circuit. The second control signal can be understood as the internal switch of the humidity monitoring module 21 closing when the logical judgment result of the temperature monitoring module meets the conditions, outputting a high level to the second logic control circuit, so that the second logic control circuit is turned on, and then the second drive device 42 is started to pump the medicine in the liquid storage device to the irrigation device 7 for spraying.
[0055] In summary, the embodiments in this specification achieve precise control of temperature and humidity inside the greenhouse through the synergistic effect of the high-precision temperature monitoring module 11 and the logic circuit, ensuring the optimal state of the crop growth environment and improving yield and quality.
[0056] Furthermore, in order to more accurately monitor pests in the greenhouse, the pest monitoring device 3 includes a pest monitoring module 31 and a third logic control circuit; the signal output terminal of the pest monitoring module 31 is connected to the third logic control circuit, and the pest monitoring module 31 is configured to send a third control signal to the third logic control circuit when it detects that the level of pests in the greenhouse is higher than a third threshold. The third logic control circuit is energized upon receiving the third control signal and controls the third drive device 43 to start.
[0057] Specifically, the four pests monitoring module 31 is a four pests monitoring station that can monitor the types and quantities of pests in the greenhouse in real time through high-precision sensors. Based on the collected data, it makes logical judgments and sends a third control signal to the third logic control circuit when the judgment results meet the conditions. The third control signal can be understood as the temperature monitoring module outputting a high level to the third logic control circuit when the logical judgment results meet the conditions, so that the third logic control circuit is turned on and the third drive device 43 is started, which pumps the insecticide in the liquid storage device to the spraying device.
[0058] In summary, the embodiments in this specification achieve precise control of pests in greenhouses through the synergistic effect of the high-precision pest monitoring module 31 and logic circuits, ensuring a healthy and stable crop growth environment and further improving the yield and quality of crops in greenhouses.
[0059] Furthermore, to facilitate control of the liquid spraying state in the irrigation equipment 7, the greenhouse control system also includes: an auxiliary control circuit 8, an auxiliary drive device 9, and an air compressor device 10; the auxiliary control circuit 8, the auxiliary drive device 9, and the air compressor device 10 are connected in sequence, and the auxiliary control circuit 8 is configured to control the auxiliary drive device 9 to deliver high-pressure gas to the irrigation equipment 7 when the auxiliary switch is closed, and then spray it out after mixing with the liquid in the irrigation equipment 7.
[0060] Specifically, the auxiliary control circuit 8 includes a fourth contactor, a start button, a stop button, and a fourth circuit protection device. One end of the fourth circuit protection device is connected to the positive terminal of the power supply, and the other end is connected to one end of the stop button. The other end of the stop button is connected to one end of the start button. The other end of the start button is connected to one end of the contactor coil. The other end of the contactor coil is connected to the negative terminal of the power supply. Auxiliary contacts are connected in parallel across the start button: one end of the auxiliary contact is connected between the stop button and the start button, and the other end of the auxiliary contact is connected between the start button and the contactor coil.
[0061] See Figure 2When the start button SB2 is closed, the contact coil of the fourth contactor KM4 is energized, the main contacts of the fourth contactor close, and the auxiliary contact (normally open) closes, forming a self-locking circuit. After the start button SB2 is released, current flows through the auxiliary contact to keep the coil energized, and the auxiliary drive device 9 continues to operate. When the stop button SB1 is pressed, the coil is de-energized, the main contacts and auxiliary contacts open, and the auxiliary drive device 9 stops operating.
[0062] The first drive device 41, second drive device 42, third drive device 43, and auxiliary drive device 9 in the embodiments of this specification can specifically be a three-phase motor or other forms of power device. The first circuit protection device 123, second circuit protection device 223, third circuit protection device 323, and fourth circuit protection device can be thermal fuses, air circuit breakers, thermal relays, or other overload protection components; this specification does not impose specific limitations on these embodiments. Figure 2 As shown, FU1, FU2, FU3, and FU4 are thermal circuit breakers, QF is an air circuit breaker, and FR1, FR2, FR3, and FR4 are thermal relays.
[0063] Furthermore, the auxiliary drive device 9 can pump air into the air compressor, which compresses the air to form high-pressure gas, which is then transported through pipelines to the irrigation equipment 7 and sprayed evenly after being mixed with the liquid.
[0064] In one embodiment of this specification, the air compressor 10 is equipped with a pressure sensor to monitor the gas pressure in real time. When the gas pressure is higher than a preset pressure threshold, the compressor stops working; when the pressure is less than or equal to the preset pressure threshold, the air compressor starts automatically.
[0065] In summary, the embodiments of this specification, by setting up auxiliary control circuit 8 and auxiliary drive device 9, achieve precise control of irrigation equipment 7, ensure uniform mixing of liquid and high-pressure gas during the irrigation process, further improve the spraying effect, optimize the crop growth environment, and enhance the overall management efficiency of greenhouse.
[0066] Furthermore, in order to make the liquid spraying more even, the irrigation equipment 7 includes: a first spraying device 71, a second spraying device 72, and a support base 73; the first spraying device 71 and the second spraying device 72 are respectively connected to both sides of the support base 73, and the bottom of the support base 73 is provided with a pulley 74. The support base 73 is configured to move through the pulley 74 and drive the first spraying device 71 and the second spraying device 72 to move.
[0067] Specifically, the first liquid storage device 5 outputs its stored liquid through the first pipeline, and the second liquid storage device 6 outputs its stored liquid through the second pipeline. The downstream of the first and second pipelines merge into a main pipeline, which branches downstream into the third and fourth pipelines, respectively connecting to the first spraying device 71 and the second spraying device 72, ensuring uniform liquid distribution and achieving all-round coverage spraying. The air compressor outputs high-pressure gas through the fifth pipeline, which branches downstream into the sixth and seventh pipelines, respectively connecting to the first spraying device 71 and the second spraying device 72. The high-pressure gas and liquid mix within the spraying devices, causing the liquid to be sprayed out in a mist, resulting in a wider coverage area and a finer spraying effect, effectively improving irrigation uniformity. The spraying range is adjusted by moving the support base 73 via the pulley 74, further enhancing irrigation uniformity.
[0068] In one embodiment of this specification, the first spraying device 71 and the second spraying device 72 can rotate independently relative to the base and adjust their angles to adapt to the different growth needs of crops, flexibly adjust the spraying direction, and ensure that crops receive uniform irrigation.
[0069] In summary, the embodiments described in this specification achieve comprehensive coverage of the irrigated area through refined pipeline design and flexible spray device configuration, ensuring that each crop receives uniform water and nutrients, thereby significantly improving crop yield and quality.
[0070] Furthermore, the first spraying device 71 includes a first nozzle array 711 and a first mixing chamber 712. The first mixing chamber 712 has a columnar structure, and the first nozzle array 711 is evenly distributed on the sidewall of the first mixing chamber 712 and communicates with the first mixing chamber 712. The second spraying device 72 includes a second nozzle array 721 and a second mixing chamber 722. The second mixing chamber 722 has a columnar structure, and the second nozzle array 721 is evenly distributed on the sidewall of the second mixing chamber 722 and communicates with the second mixing chamber 722.
[0071] Specifically, the first mixing chamber 712 is connected to the first and sixth pipes, and the second mixing chamber 722 is connected to the second and seventh pipes. After the high-pressure gas and liquid are fully mixed in their respective mixing chambers, they are evenly sprayed out through the nozzle array to form a fine mist with a wider coverage area. The first and second mixing chambers 712 and 722 are stacked and connected on both sides of the support base 73 to ensure synchronous spraying on both sides, further enhancing spray uniformity. The number and arrangement of nozzles in the columns of the first nozzle array 711 and the second nozzle array 721 are not specifically limited and can be flexibly adjusted according to actual needs to adapt to different irrigation scenarios.
[0072] In another embodiment of this specification, the first spraying device includes a first two-fluid atomizing nozzle array and a first nozzle support frame. The first two-fluid atomizing nozzle array is uniformly fixed on the first nozzle support frame. The second spraying device includes a second two-fluid atomizing nozzle array and a second nozzle support frame. The second two-fluid atomizing nozzle array is uniformly fixed on the second nozzle support frame. The first nozzle support frame and the second nozzle support frame are symmetrically connected to both sides of the support base.
[0073] In summary, the embodiments described in this specification achieve efficient and uniform irrigation through scientific pipeline layout and nozzle design.
[0074] Furthermore, the first logic control circuit includes a first relay 121, a first contactor 122, and a first circuit protection device 123; the first relay 121 is connected to the auxiliary contacts of the first contactor 122, and the first circuit protection device 123 and the main contacts of the first contactor 122 are sequentially connected to the first driving device 41.
[0075] Specifically, the AC220V to DC24V transformer is connected to the positive terminal of the power supply to convert 220V AC power to 24V DC power. The AC220V to DC24V transformer, temperature monitoring module 11, first relay 121, auxiliary contacts of first contactor 122, and negative terminal of the power supply are connected in sequence. The positive terminal of the power supply, first circuit protection device 123, main contacts of first contactor 122, and first drive device 41 are connected in sequence. When the temperature monitoring module 11 detects that the temperature is greater than the first threshold, the switch inside the temperature monitoring module 11 closes and outputs a high level. The coil of first relay 121 is energized and its contacts close. The coil of first contactor 122 is energized, its auxiliary contacts close, its main contacts close, and the first drive device 41 starts, drawing clean water from the clean water tank and pumping it to the irrigation equipment 7 for spraying.
[0076] In summary, the embodiments in this specification, through precise temperature control and circuit protection mechanisms, ensure that the system sprays water to cool down in a timely manner under high temperature conditions, effectively preventing crops from being damaged by high temperatures and ensuring the stability and safety of the crop growth environment.
[0077] Furthermore, the second logic control circuit includes a second relay 221, a second contactor 222, and a second circuit protection device 223; the second relay 221 is connected to the auxiliary contacts of the second contactor 222, and the second circuit protection device 223, the main contacts of the second contactor 222, and the second drive device 42 are sequentially connected.
[0078] Specifically, the AC220V to DC24V transformer, humidity monitoring module 21, second relay 221, auxiliary contacts of second contactor 222, and negative power supply are connected in sequence. The positive power supply, second circuit protection device 223, main contacts of second contactor 222, and second drive device 42 are connected in sequence. When the humidity monitoring module 21 detects that the humidity is less than the second threshold, the switch inside the humidity monitoring module 21 closes and outputs a high level. The coil of second relay 221 is energized and its contacts close. The coil of second contactor 222 is energized, its auxiliary contacts close, its main contacts close, and the second drive device 42 starts, drawing clean water from the clean water tank and pumping it to the irrigation equipment 7 for spraying.
[0079] In summary, the embodiments in this specification, through intelligent humidity monitoring and circuit control, ensure timely water replenishment of the system in dry environments, effectively preventing crop damage due to water shortage, and further improving the suitability of the crop growth environment and yield stability.
[0080] Furthermore, the third logic control circuit includes a third relay 321, a third contactor 322, and a third circuit protection device 323; the third relay 321 is connected to the auxiliary contacts of the third contactor 322, and the third circuit protection device 323, the main contacts of the third contactor 322, and the third driving device 43 are sequentially connected.
[0081] Specifically, the AC220V to DC24V transformer, the pest monitoring module, the auxiliary contacts of the third relay 321 and the third contactor 322, and the negative terminal of the power supply are connected in sequence. The positive terminal of the power supply, the third circuit protection device 323, the main contacts of the third contactor 322, and the third drive device 43 are connected in sequence.
