[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a device for synchronously acquiring images and temperature and humidity of tobacco leaves in a tobacco curing barn, comprising: a temperature and humidity acquisition component, an image acquisition component, an industrial control computer 10, and a data acquisition box 4. The temperature and humidity component includes a temperature and humidity data acquisition device 13 and a temperature and humidity sensing probe 3, which are connected via a data bus. The image acquisition component includes a camera 1 and a barrier component 2, which is used to block the tobacco leaves to ensure that the camera's field of view is within a suitable range. The image acquisition component is connected to the industrial control computer 10 via a network interface. The industrial control computer is equipped with data acquisition and control software and is capable of data storage. The data acquisition box 4 contains the temperature and humidity acquisition component, the image acquisition component, and the industrial control computer 10, and is installed outside the curing barn.
[0025] Specifically, the temperature and humidity sensor 3 monitors and collects temperature and humidity information of the tobacco leaves. Multiple acquisition cameras 1 can be installed at designated locations inside the curing barn to capture real-time images of the tobacco leaves, allowing for observation of the curing process and timely adjustments to ensure the quality of the tobacco curing. Simultaneously, the external baffle components of the acquisition cameras 1 effectively protect them, ensuring a stable viewing angle and minimizing any impact on the tobacco drying quality. The information acquisition components inside the data acquisition box 4 collect and process the tobacco leaf information, providing feedback to operators for convenient adjustments to the temperature and humidity during tobacco drying.
[0026] Reference Figure 1 and Figure 2 The partition assembly 2 includes an upper baffle 7, a top frame 5 fixedly connected to the outside of the upper baffle 7, two U-shaped brackets 6 fixedly connected to the bottom of the upper baffle 7, a lower baffle 8 fixedly connected to the bottom of the U-shaped bracket 10, and a shielding area 9 formed between the upper baffle 7 and the lower baffle 8. The two ends of the upper baffle 7 are longer than the distance between the two U-shaped brackets 6 by at least 5 cm, the distance between the upper baffle 7 and the lower baffle 8 is at least 10 cm, and the distance between the upper baffle 7 and the lower baffle 8 is 5-10 cm. The upper baffle 7 and the top frame 5 are integrally forged using a suitable material. The number of temperature and humidity sensing probes 3 and the number of acquisition cameras 1 are the same.
[0027] Specifically, the upper baffle 7 must be at least 10cm longer than the lower baffle 8, and the widths of the upper baffle 7 and 8 must be consistent. This ensures that the camera 1 is not affected by airflow and that the tobacco leaves being photographed maintain normal ventilation during the baking process. Meanwhile, the outer sides of the U-shaped frames 10 on both sides are secured with mechanical screws and matching nuts or by wrapping themselves with barrier wires. This effectively blocks the expanding lower half of the tobacco leaves, ensuring good acquisition results for the camera 11 while minimizing the impact of the barrier device on the quality of tobacco leaf baking. The top frame and the upper baffle 3 can be integrally forged using suitable materials, facilitating on-site installation of the device.
[0028] Reference Figure 1 and Figure 2 It also includes a field switch 16 for the drying room, a switching power supply 11, and a switch 12. The field switch 16 is located inside the drying room, the switching power supply 11 is located inside the data acquisition box 4, the switching power supply 8 obtains external power supply through the power cord 14, the switch 12 is connected to the acquisition camera 1 through the field switch 16 and the broadband network cable 15, the temperature and humidity data acquisition device 13 is connected to the temperature and humidity sensor probe 3 through the matching line, and the switching power supply 11 is electrically connected to the industrial control computer 10 and the acquisition camera 1 respectively.
[0029] Specifically, the switching power supply 11 obtains external power through the power cord 14 to power other devices, thus connecting the switching power supply 8 to the acquisition camera 11 via the power cord 14 to maintain the power supply to the acquisition camera 1. The switch 6 is connected to the on-site switch 6 in the curing barn via a broadband network cable, providing internet connectivity for the acquisition camera 1, enabling remote control and real-time viewing. The temperature and humidity data acquisition device 13 is connected to the switching power supply 11 via the power cord 14 to ensure normal operation. Simultaneously, the temperature and humidity data acquisition device 13 is connected to the temperature and humidity sensor probe 3 via a matching line to acquire real-time temperature and humidity data. The industrial control computer 10 is connected to the switch 12 via a broadband network cable to stably connect to the internet and enable subsequent remote control. The industrial control computer 10 needs to install data acquisition software to realize the acquisition settings and local storage of various data, thereby realizing real-time information acquisition of tobacco leaf data, reducing the labor intensity of workers, facilitating the control of temperature and humidity in the curing barn, and improving the curing quality of tobacco leaves.
[0030] Working principle: During the tobacco curing process, the acquisition camera 1 captures images of the tobacco leaves and transmits them to the industrial control computer 10 in the data acquisition box 4 to collect the image information. The upper baffle 7 and the lower baffle 8 work together to protect the acquisition camera 1, ensuring good image acquisition while reducing the impact of the device on the tobacco curing quality. The temperature and humidity acquisition component collects the temperature and humidity of the tobacco leaves and transmits it to the temperature and humidity acquisition unit 7 through the matching line. After information processing, real-time monitoring and acquisition of the temperature and humidity of the tobacco leaves can be achieved, which facilitates timely adjustment of the temperature and humidity during tobacco curing and ensures the curing quality of the tobacco leaves.
