Description

Technical Field

[0002] The statements in this section are merely background information relating to this disclosure and do not necessarily constitute prior art.

[0003] In existing technologies, flower care devices typically consist of independent modules such as environmental monitoring systems and automatic irrigation systems, resulting in relatively limited functionality. These devices usually only meet a portion or a few aspects of flower care needs. Due to the dispersed operation of the modules and the lack of effective system integration, multiple devices or equipment need to work together. However, existing devices lack intelligent flower care systems that integrate functions such as watering, supplemental lighting, pest control, and soil loosening. Furthermore, with the integration of functional modules, especially the introduction of camera modules, the required number of pins is increased, leading to insufficient pin resources for the STM32F1 series main control chip, making it difficult to simultaneously meet the needs of multiple modules working collaboratively. At the same time, the integrated device experiences a significant increase in power consumption and low energy efficiency, and cannot achieve automatic switching between different power supply methods.

[0041] Example 1

[0042] like Figure 1 and Figure 3 This utility model provides a low-power multimodal intelligent flower maintenance device, which adopts a dual STM32 main control architecture and is prototyped based on a breadboard. The dual STM32 main control architecture includes two STM32F103C8T6 main control chips, which are respectively referred to as the image acquisition main control chip and the execution function main control chip.

[0060] The watering module is directly connected to the third relay via the YL69 soil moisture sensor to ensure that the water pump starts and stops automatically within the soil moisture threshold.

[0061] The working principle of this utility model is as follows:

[0062] like Figure 1 , Figure 2 , Figure 3 When the INA226 voltage detector detects that the output voltage of the solar panel (115) is higher than the set threshold, the main control chip (302) executes the function via I... 2The controller receives voltage data and controls the PB14 pin to output a high level, driving the first relay to engage, making the NO1 terminal and COM1 terminal conduct, and the system switches to the solar panel power supply mode. At the same time, the main control chip controls the PB15 pin to output a low level, making the second relay disengage, cutting off the lithium battery power supply path to reduce lithium battery consumption. When the INA226 voltage detector detects that the output voltage of the solar panel (115) is lower than the set threshold (e.g., at night or on a cloudy day), the main control chip (302) controls the PB14 pin to output a low level, making the first relay disengage, cutting off the solar panel power supply path; at the same time, it controls the PB15 pin to output a high level, making the second relay engage, making the NO2 terminal and COM2 terminal conduct, and the system automatically switches to the lithium battery (116) power supply mode to ensure normal operation of the device. In addition, the LM1117-3.3V module outputs a 5V voltage through the combined output of the COM terminals of the first and second relays, and outputs a 3.3V voltage at the output terminal to provide a stable power supply for the main control chip.

[0063] like Figure 1 , Figure 3The crop growth images acquired by the OV7670 camera module (107) are compressed by the image acquisition main control chip (301) and transmitted to the execution function main control chip (302) through the USART1 serial port PA9 / TX (303) and PA10 / RX (304). The execution function main control chip (302) uploads the image data to the cloud processing system through the ESP01S WiFi module (117). When the cloud image recognition system detects soil compaction characteristics, it returns a high-level signal to the execution function main control chip (302). After receiving the high-level signal, the execution function main control chip (302) activates channel 1 (PA0) of the TIM2 timer to output a PWM signal (pulse width 2ms) with a period of 20ms and a duty cycle of 10%. This drives the third SG90 servo motor (113) to drive the loosening fork (114) to complete a 180° rotation loosening action. After the loosening fork completes 3 reciprocating motions, the PA0 pin automatically returns to a low level, and the servo motor returns to the initial angle. When the cloud-based analysis of image data identifies pest activity characteristics, the main control chip (302) outputs a 10μs-width 5V TTL pulse signal through the PA4 pin, triggering the ultrasonic transmitter (109) to generate a 40kHz insect-repelling sound wave and simultaneously start the dual-axis gimbal scanning program: Vertical direction control: The first SG90 servo drives the gimbal to complete the 0°→90°→0° pitch scan (one-way time 1.2 seconds) by outputting a 15ms period, 50% duty cycle PWM signal through PB10 (TIM2_CH3). Horizontal direction control: The second SG90 servo drives the gimbal to complete the 0°→120°→0° horizontal scan (one-way time 2 seconds) by outputting a 20ms period, 75% duty cycle PWM signal through PA1 (TIM2_CH2). When the duration of ultrasonic transmission reaches the 300-second threshold preset by the cloud, the PA4 pin automatically drops to a low level, terminating the insect-repelling operation.

[0064] like Figure 1 and Figure 3When the BH1750 (102) light sensor detects that the ambient light intensity is lower than the set value, the execution function main control chip (302) receives the data from the light sensor via I2C and controls the PB8 pin to output a high level, driving the LED supplemental light (101) to light up and provide supplemental lighting for the flowers. When the ambient light intensity reaches the set value, the execution function main control chip (302) controls the PB8 pin to output a low level, turning off the LED supplemental light to save energy. In addition, users can manually adjust the light threshold or directly control the on / off state of the LED supplemental light (101) via the cloud to adapt to the growth needs of different flowers. When the DS18B20 temperature sensor (106) detects that the ambient temperature is lower than the set value, the execution function main control chip controls PB0 to output a high level, the dual relays are energized, NO1 and COM1 are shorted, and the heating element (102) starts working; when the ambient temperature is higher than the set value, the execution function main control chip (302) controls PB1 to output a high level, the dual relays are energized, NO2 and COM2 are shorted, and the cooling element (112) and the cooling fan (111) start working. When the analog voltage value output by the YL69 soil moisture sensor (103) is lower than the humidity threshold set by the cloud, the execution function main control chip outputs a high level on pin PA6, driving the third relay to energize, and the water pump (104) starts to supply water; the user can manually open the water tank door (105) to control the addition of water to the tank. The water pump (104) supplies water until the output voltage of the soil moisture sensor reaches the upper limit of the threshold set by the cloud, at which point the PA6 pin outputs a low level, and the water pump (104) stops working.

[0065] In the description of this specification, the terms "connection", "installation", "fixing", "setting", etc. are interpreted in a broad sense. For example, "connection" can be a fixed connection or an indirect connection through an intermediate component without affecting the relationship between components and the technical effect. It can also be an integral connection or a partial connection.
