Description

Technical Field

[0001] This invention relates to the field of manufacturing technology for special equipment for tea production, specifically a machine that integrates flower cultivation and scenting. Background Technology

[0002] The scenting process of tea includes steps such as fresh flower care, scenting, ventilation and re-scenting, flower removal, and drying of the wet tea leaves. In the traditional process, the fresh flower care and scenting steps are often carried out separately. First, the selected fresh flowers are cared for, and when the flowers have reached 85% of their unfolded state, they are mixed with tea leaves and left to stand. This separate process results in low processing efficiency, and some of the floral fragrance is lost during the flower care process, resulting in less floral fragrance remaining after being mixed with tea leaves, and less floral fragrance being obtained by the tea leaves.

[0003] Furthermore, the ventilation method used is natural airflow, without temperature detection components, making it impossible to obtain the temperature of the tea pile in real time. When the outside temperature changes, it cannot make timely adjustments accordingly. The existing process also lacks intelligent humidity detection functions, making it impossible to obtain the humidity of the environment where the flowers are grown and scented in a timely manner.

[0004] Through research and comparison, the present invention provides an integrated flower cultivation and scenting machine that combines the flower cultivation and scenting steps into one process. That is, when the flowers are being cultivated, the tea leaves are mixed with the flowers to form a tea pile, which increases the amount of floral fragrance that the tea leaves can absorb. It is also equipped with intelligent temperature and humidity detection to achieve automated flower cultivation and scenting.

[0005] Therefore, a flower-growing and scenting integrated machine is proposed. Summary of the Invention

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A flower-growing and scenting integrated machine includes a scenting machine, an electrical control cabinet, and an air conditioner. The scenting machine and the electrical control cabinet are both placed in a prefabricated house. The scenting machine is electrically connected to the electrical control cabinet via wires, and the air conditioner is also electrically connected to the electrical control cabinet. A PLC controller is installed inside the electrical control cabinet. A mounting frame is fixedly installed on the side wall of the scenting machine, and a camera is fixedly installed on the mounting frame. A temperature detection component is fixedly installed inside the scenting machine.

[0008] The electrical control cabinet is equipped with an intelligent control system, which includes a PLC controller, a temperature detection module, a humidity detection module, and an oxygen content detection module. The temperature detection module, humidity detection module, and oxygen content detection module are all electrically connected to the PLC controller.

[0009] More specifically, the scenting machine adopts a multi-layer chain dryer. Multiple conveyor belts are arranged vertically on the machine, staggered and with each pair of adjacent conveyor belts running in opposite directions, causing the scented tea to traverse in an S-shape. The electrical control cabinet contains a PLC controller, integrated circuits, leakage circuit breakers, etc. The cabinet also features a start button, display screen, emergency stop button, power knob, and touchscreen for human-machine interaction. The display screen shows the temperature value detected by the temperature detection component in real time, and also displays images of the scented tea captured by the camera.

[0010] The integrated flower growing and scenting machine also includes conveyor 1, conveyor 2, conveyor 3, conveyor 4, conveyor 5, conveyor 6, and conveyor 7, a shaking screen and a flower mixing machine. The bottom of conveyor 6 is connected to the bottom of the scenting machine and is connected to the bottommost conveyor belt of the scenting machine. Conveyor 5 is located behind conveyor 6. Conveyor 3 is located on the side of conveyor 6 and is connected to conveyor 5. Conveyor 1 is located on the right side of the scenting machine and is connected to conveyor 3. The top of the scenting machine is equipped with a spreading hopper, and conveyor 1 is connected to the spreading hopper.

[0011] Preferably, the temperature detection component includes an electric rod and a temperature probe. The electric rod is fixedly installed on the crossbar of the scenting machine, and the temperature probe is fixedly installed on the output end of the electric rod. The electric rod is electrically connected to the electrical control cabinet via a wire.

[0012] The PLC controller controls the start and extension of the electric rod. When the PLC controller controls the conveyor belt to stop running, it controls the output end of the electric rod to extend downward, so that the temperature probe can be inserted into the tea pile to detect the temperature of the tea pile.

[0013] The camera is connected to the PLC controller via a signal transmission line. The PLC controller is equipped with an image recognition system. The image recognition system detects the image acquired by the camera, analyzes the acquired image to determine whether the flowers are 85% open, and displays the acquired image and data on the display screen of the electrical control cabinet. The PLC controller controls the rotation of the conveyor.

[0014] Preferably, the interior of the scenting machine is connected to the exterior, and the ventilation method is to introduce natural air. The temperature detection module detects the temperature values ​​of the natural air and the tea pile, the oxygen content detection module detects the oxygen content value of the natural air, and the humidity detection module detects the air humidity value inside the prefabricated house.

[0015] Preferably, a temperature sensor is fixedly installed on the mounting bracket, a humidity sensor is fixedly installed on the side wall of the scenting machine, the humidity sensor is electrically connected to the humidity detection module, the temperature sensor is electrically connected to the temperature detection module, and an oxygen content detector is also fixedly installed on the side wall of the scenting machine, the oxygen content detector is electrically connected to the oxygen content detection module.

[0016] The temperature sensor is used to detect the internal temperature of the prefabricated house and feed the temperature value back to the temperature detection module.

[0017] Furthermore, an air conditioner is placed on one side of the air-purifying machine. The air conditioner has heating, cooling, and dehumidification functions. The air conditioner is used to regulate the indoor air temperature and humidity. The PLC controller regulates the temperature of the gas output by the air conditioner based on the temperature value fed back by the temperature sensor.

[0018] The humidity sensor detects the air humidity around the air freshener and feeds the air humidity value back to the humidity detection module. The PLC controller then activates the dehumidification function of the air conditioner based on the humidity value reported by the humidity detection module.

[0019] Furthermore, the oxygen content detector monitors the oxygen content inside the prefabricated house in real time and feeds it back to the oxygen content detection module. The oxygen content detection module determines the oxygen content of the indoor air. If the indoor oxygen content is detected to be low, the signal is transmitted to the PLC controller. The PLC controller controls the air conditioner to increase the airflow and the rate of indoor and outdoor air exchange to ensure that the indoor oxygen content is maintained within a constant range.

[0020] The image recognition system includes an image recognition model that uses a convolutional neural network to recognize images acquired by the camera. The convolutional neural network uses Google Inception V3. The specific steps are as follows: the original image acquired by the camera is converted into a grayscale image, then Gaussian filtering is used to denoise the grayscale image, the denoised grayscale image is binarized to obtain the boundary of the tea leaf area, the original image is cropped according to the boundary, and HourglassNet is used to label the base, tip, and edge points of the petals to comprehensively calculate the petal spread.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. Equipped with an electrical control cabinet, temperature detection components, and oxygen content detection module, etc., the electrical control cabinet and temperature detection components are used to detect and control the ambient temperature inside the prefabricated room and the internal temperature of the camellia pile in real time. Based on the obtained temperature value of the camellia pile, the running speed of the conveyor belt on the scenting machine is adjusted to adjust the scenting time and ensure that the tea leaves absorb the aroma of fresh flowers better.

[0023] 2. A mounting frame is fixedly installed on the side wall of the scenting machine, and a camera is fixedly installed on the mounting frame. The camera is used to observe the mixture of tea leaves and fresh flowers on the scenting machine, obtain real-time images of the flowers, and analyze the degree of flower unfolding. When the degree of flower unfolding reaches 85%, the data is displayed on the screen, and the PLC controller is instructed to control the conveyor to rotate and introduce the flowers into the shaking sieve to remove impurities such as buds and stems in the mixture.

[0024] 3. Temperature probe and electric rod: The electric rod is telescopic and is fixedly installed at the bottom of the crossbar inside the scenting machine. The temperature probe is fixedly installed at the output end of the electric rod. The PLC controls the electric rod to telescopically operate. When the motor stops rotating, the conveyor belt also stops running. At this time, the output end of the electric rod moves downward, so that the temperature probe contacts and extends into the tea pile to obtain the temperature value inside the tea pile and feeds it back to the temperature detection module. The temperature detection module sends the analysis results to the PLC control, and the PLC controller adjusts the motor speed to adjust the overall scenting time.

[0025] 4. A convolutional neural network, Google Inception V3, was used as the image recognition model. Gaussian filtering was used to denoise the grayscale image. The denoised grayscale image was then binarized to obtain the boundary of the tea leaf area. The original image was cropped based on the boundary. HourglassNet was used to annotate the base, tip, and edge points of the petals, and the petal spread was calculated. Attached Figure Description

[0037] The camera 12 is connected to the PLC controller via a signal transmission line. The electrical control cabinet 3 is equipped with an image recognition system, which is electrically connected to the PLC controller.

[0039] The interior of the scenting machine 2 is connected to the exterior, and the ventilation method is to introduce natural air. The electrical control cabinet 3 is equipped with a temperature detection module, a humidity detection module, and an oxygen content detection module.

[0040] A temperature sensor 10 is fixedly installed on the mounting bracket 5, and a humidity sensor 14 is fixedly installed on the side wall of the scenting machine 2.

The indoor temperature sensor 10 detects the air temperature inside the model room 1 and feeds the temperature value back to the temperature detection module. The temperature detection module determines whether the indoor temperature is between 23℃ and 27℃.

[0042] If the indoor temperature is less than 23℃, the PLC controller will control the air conditioner 4 to deliver hot air into the prefabricated house 1 to raise the temperature. If the detected temperature is greater than 27℃, the PLC controller will control the air conditioner 4 to output cold air to lower the temperature inside the prefabricated house, so that the temperature inside the prefabricated house 1 is maintained between 23℃ and 27℃.

[0043] The electric rod 11 is electrically connected to the PLC controller via wires. The electric rod 11 is fixedly installed on the middle crossbar of the scenting machine 2. A temperature probe 13 is fixedly installed on the output end of the electric rod 11. The temperature probe 13 is made of stainless steel. The temperature probe 13 is used to periodically extend into the surface and interior of the flower tea pile to detect the surface or interior temperature of the flower tea in order to obtain a more accurate temperature value.

[0044] The image recognition model is based on a convolutional neural network to recognize images acquired by the camera. The convolutional neural network uses Google Inception V3. The specific steps are as follows: the original image acquired by the camera is converted into a grayscale image, then Gaussian filtering is used to denoise the grayscale image, the denoised grayscale image is binarized to obtain the boundary of the tea area, the original image is cropped according to the boundary, and HourglassNet is used to label the base, tip, and edge points of the petals to comprehensively calculate the petal spread.

[0045] Example 1

[0046] During the flower-growing process, press the start button on the electrical control cabinet to start the entire system.

[0047] Fresh flowers are manually placed onto conveyor 218, where they fall onto conveyor 17 and are then transported into spreading hopper 26. The spreading hopper 26 smooths the flowers and spreads them evenly on the conveyor belt of the scenting machine, achieving a thickness of 20cm-30cm. The flowers are then transported layer by layer on the conveyor belt of the scenting machine.

[0048] When detecting the surface or internal temperature of the flower tea, the PLC controller controls the motor 16 to stop rotating, starts the electric rod 11 so that the output end of the electric rod 11 extends downward, so that the temperature probe 13 contacts the surface and / or internal part of the flower tea to obtain the temperature of the flower tea. The detection time lasts for 2 seconds. After 2 seconds, the output end of the electric rod 11 is retracted, and the motor 16 starts and continues to rotate.

[0049] The temperature value obtained by the temperature probe 13 is transmitted to the temperature detection module for identification. The PLC controller adjusts the speed of the motor 16 according to the temperature value obtained by the temperature probe 13. If the temperature value detected by the temperature probe 13 is close to 40°C, the speed of the motor 16 is reduced to increase the curing time. If the temperature detected by the temperature probe 13 is close to 48°C, the speed of the motor is increased to reduce the overall curing time.

[0050] Flowers pass through the conveyor belt at the bottom of the scenting machine. Images captured by a camera are transmitted to a neural network system for image processing. The system determines whether the flowers are 85% open and displays the images and data on the screen of the electrical control cabinet 3. Flowers then fall onto conveyor six 22. If the flowers are less than 85% open, they fall onto conveyor five 21, then pass through conveyor three 19 and conveyor one 17 back to the scenting machine for further conditioning. This cycle continues.

[0051] If the flowers are detected to have reached 85% unfolding, the PLC controller controls conveyor 420 to rotate horizontally. Conveyor 420 is rotated to a position below conveyor 622, with its other end above the feed inlet of vibrating screen 24. Flowers passing through conveyor 622 fall onto conveyor 420, which then transports them to vibrating screen 24. Vibrating screen 24 removes impurities such as buds and stems from the flowers. The screened flowers then fall onto conveyor 7. Simultaneously, manual... Tea leaves and fresh flowers are poured into conveyor seven. The tea leaves and fresh flowers are transported to the flower mixing machine 25 via conveyor seven. The flower mixing machine is started to stir the mixture of tea leaves and fresh flowers. The stirred mixture of tea leaves and fresh flowers is transported to conveyor one 17 via conveyor two 18, and then enters the spreading hopper 26 on the scenting machine via conveyor one 17. The tea and flower mixture flows through the scenting machine, conveyor six 22, conveyor five 21, conveyor three 19 and conveyor one 17 in sequence, and is scented for 8 to 12 hours.

[0052] The electric motor 16 on the scenting machine 2 is a right-angle reducer servo motor, which stably outputs torque to drive the automatic opening and closing screening drum 13 to rotate precisely, meeting the needs of different processes. The servo motor has a high-precision position control function, and its encoder resolution is as high as 10,000 pulses per revolution, which can accurately control the rotation angle of the drum. Whether it is static scenting, tea flower turning and mixing, or separating tea and flowers, it can accurately position and ensure that each process link is executed in place.
