This method is not only time-consuming but also frequently suffers from delays due to human error, hindering timely adjustments to environmental factors and potentially damaging crops. Summary of the Invention

[0003] In order to solve the technical problems existing in the background art, the present invention provides an artificial intelligence control device based on the Internet of Things, which helps to realize real-time monitoring of environmental factors in greenhouses and real-time control based on monitoring results, thereby ensuring to a certain extent that crops in greenhouses are protected from damage.

[0021] Example 1: like Figure 1 and Figure 2 As shown, this embodiment provides an Internet of Things-based artificial intelligence control device, including: a microcontroller 1, an environmental factor detection module 2, an alarm module 6, a timing module 4, a communication module 7, a display module 5, and a relay drive circuit 3 for connecting to an environmental actuator.

[0022] The microcontroller 1 and the environmental factor detection module 2 are used to acquire environmental factors inside the greenhouse in real time, including temperature and humidity.

[0023] The environmental factor detection module includes: temperature sensor 2-1 and humidity sensor 2-2.

[0024] Specifically, the microcontroller 1 is connected to the temperature sensor 2-1 to acquire the temperature inside the greenhouse detected by the temperature sensor 2-1 in real time; Microcontroller 1 is connected to humidity sensor 2-2 to acquire the humidity inside the greenhouse detected by humidity sensor 2-2 in real time; The microcontroller 1 is connected to the display module 5 and is used to control the display module 5 to display the acquired environmental factor data (temperature and humidity) in real time and to preset timing thresholds and environmental factor data thresholds through the display module 5. The environmental factor thresholds include a maximum temperature threshold, a minimum temperature threshold, a maximum humidity threshold, and a minimum humidity threshold; the timing thresholds include a first timing threshold and a second timing threshold.

[0025] The microcontroller 1 is connected to the timing module 4 and is used to control the timing module to perform timing when the environmental factors acquired in real time exceed the corresponding preset environmental factor threshold. Specifically, it is used to control the timing module to start timing when either the temperature or humidity obtained in real time exceeds its corresponding preset temperature threshold range and humidity threshold range.

[0026] The timing module 4 includes a first timing module 4-1 for adjusting timing based on temperature and a second timing module 4-2 for adjusting timing based on humidity.

[0027] More specifically, when the real-time temperature is greater than the preset maximum temperature threshold or less than the preset minimum temperature threshold, the first timing module 4-1 is controlled to start timing; when the real-time humidity is greater than the preset maximum humidity threshold or less than the preset minimum humidity threshold, the second timing module 4-1 is controlled to start timing.

[0028] The microcontroller 1 is connected to the alarm module 6 and is used to control the alarm module 6 to trigger an alarm based on the timing duration and a preset timing threshold.

[0029] Specifically, when the timing duration of the first timing module exceeds the first timing threshold, the alarm is activated; when the timing duration of the second timing module exceeds the second timing threshold, the alarm is activated.

[0030] Environmental control equipment includes: heating equipment, refrigeration equipment, dehumidification equipment, and spraying equipment; The microcontroller 1 is connected to the relay drive circuit 3 and is used to send control signals to the relay drive circuit 3 based on the detected environmental factor data to control the working state of the corresponding environmental actuator. The working state includes start and stop.

[0031] The relay drive circuit 3 includes: a heating relay drive circuit 3-1 for connection with heating equipment, a refrigeration relay drive circuit 3-2 for connection with refrigeration equipment, a spray relay drive circuit 3-3 for connection with spray equipment, and a dehumidification relay drive circuit 3-4 for connection with dehumidification equipment.

[0032] The microcontroller 1 is connected to the communication module 7, which is used to send the real-time environmental factor data to the staff's portable terminal through the communication module.

[0033] Among them, communication uses wireless communication modules, such as Zigbee and nFR24l01 communication modules.

[0034] It should be noted that in practical applications, multiple different types of execution devices, as well as corresponding relay drive circuits and timing circuits and thresholds, can be set according to the actual detected environmental factors. For the sake of simplicity, this embodiment takes temperature and humidity as two environmental factors as examples.

[0035] In this embodiment, for ease of explanation and understanding, temperature and humidity are used as examples of environmental factors. The corresponding environmental factor execution devices are heating devices, cooling devices, dehumidifying devices, and spraying devices. The relay drive circuits connected to the environmental factor execution devices are heating relay drive circuits, cooling relay drive circuits, dehumidifying relay drive circuits, and spraying relay drive circuits.

[0036] First, temperature, humidity, and timing thresholds are preset via the display module. Temperature and humidity sensors monitor the greenhouse temperature and humidity in real time and transmit the data to the microcontroller. The microcontroller then sends the received real-time temperature and humidity readings to a worker's portable terminal via the communication module, where they are displayed in real-time. Simultaneously, the received temperature and humidity readings are compared to the preset temperature and humidity thresholds. If the detected temperature exceeds the preset maximum temperature threshold, a signal is sent to the refrigeration relay drive circuit. The refrigeration equipment is activated by closing the relay in the refrigeration relay drive circuit to cool the greenhouse. At the same time, the first timing module starts timing. If the temperature of the greenhouse is less than the preset maximum temperature threshold within the preset first timing threshold, the alarm will not sound. If the temperature of the greenhouse is not less than the preset maximum temperature threshold within the preset timing threshold, the alarm will sound.

[0037] If the detected temperature is lower than the preset minimum temperature threshold, a signal is sent to the heating relay drive circuit. The relay in the heating relay drive circuit closes, causing the heating equipment to work and heat the greenhouse. At the same time, a timer is started. If the temperature of the greenhouse is higher than the preset minimum temperature threshold within the preset timer threshold, the alarm will not sound. If the temperature of the greenhouse is not higher than the preset minimum temperature threshold within the preset timer threshold, the alarm will sound.

[0038] If the detected humidity is less than the preset minimum humidity threshold, a signal is sent to the spray relay drive circuit. The relay in the spray relay drive circuit closes, causing the spray equipment to work and spray the greenhouse. At the same time, the timer is started. If the humidity in the greenhouse is greater than the preset minimum humidity threshold within the preset timer threshold, the alarm will not sound. If the humidity in the greenhouse is not greater than the preset minimum humidity threshold within the preset timer threshold, the alarm will sound.

[0039] If the detected humidity exceeds the preset maximum humidity threshold, a signal is sent to the dehumidification relay drive circuit. The relay in the dehumidification relay drive circuit closes, causing the dehumidification equipment to operate and spray the greenhouse. Simultaneously, a timer is started. If the humidity in the greenhouse is less than the preset maximum humidity threshold within the preset timer threshold, the alarm will not sound. If the humidity in the greenhouse is not less than the preset maximum humidity threshold within the preset timer threshold, the alarm will sound.

[0040] Example 2: In this example, the relay drive circuit currently used in actual use is as follows: Figure 2 As shown, since microcontrollers typically control multiple relay drive circuits, the currently used relay drive circuits cannot visually indicate which relay drive circuit is running. In addition, when the voltage output by the microcontroller is too low, the current through the relay coil will be too low, making it impossible to drive the relay normally.

[0041] To address these issues, the relay driver circuit in this embodiment connects a light-emitting diode in parallel across the coil. When the microcontroller outputs a high level, the LED will light up when the relay starts normally, allowing operators to visually identify which relay driver circuit is operating. Furthermore, by connecting a pull-up resistor connected to VCC in parallel at the microcontroller output, the base input current of the transistor is increased, thereby achieving the purpose of driving the relay and avoiding the problem of the relay coil failing to start when the microcontroller output voltage is too low.

[0042] Specifically, such as Figure 3 As shown, the relay driving circuit provided in this embodiment includes: a first resistor R1, the first end of which is connected to the output port of the microcontroller 1 and the first end of the second resistor R2, and the second end of the first resistor R1 is connected to the power supply VCC; the second end of the second resistor R2 is connected to the base of the transistor Q1, and the emitter of the transistor Q1 is grounded; the collector of the transistor Q1 is connected to the anode of the first diode D1, the cathode of the second light-emitting diode D2, and the first terminal KA-5 of the relay coil; the second terminal KA-4 of the relay coil, the cathode of the first diode D1, and the anode of the second light-emitting diode D2 are connected to the power supply VCC through a third resistor R3; the common terminal K1-1 of the relay switch K1 is connected to the first pin J-1 of the connector J1; the normally closed contact common terminal K1-3 of the relay switch K1 is connected to the second pin common terminal J1-2 of the connector J1.

[0043] In this embodiment, the microcontroller can be an STM32 series microcontroller.
