[0028] In order to enable those skilled in the art of this technology to better understand the solution of the present invention, the following will further elaborate on the present invention in combination with specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.
[0029] The following is a preferred embodiment:
[0030] As Figure 1-2 shown, a tobacco leaf grading monitoring method in this embodiment includes a mounting bracket, on which a grading monitoring terminal is provided. A supplementary light is provided outside the grading monitoring terminal. The grading monitoring terminal is used to detect the tobacco basket tobacco leaves to be weighed, take high-definition photos of the tobacco leaves in the lower tobacco basket, and transmit the tobacco leaf photos to the acquisition host through the network unit;
[0031] The tobacco basket tobacco leaves to be weighed are placed on the weighing platform of the electronic scale. An overweigh integrated machine is placed on one side of the weighing platform of the electronic scale. An RFID is built in on the side close to the tobacco basket tobacco leaves to be weighed. A scale head and a tablet computer are also provided inside. The weighing platform of the electronic scale communicates with the RFID scale head. The weighing sensor weighs the tobacco leaf weight, and conveys the tobacco basket tobacco leaves to be weighed to the overweigh integrated machine. The overweigh integrated machine is transmitted to the acquisition host through the network unit.
[0032] Among them, a POE interface is provided outside the grading monitoring terminal. The internal camera uses multiple glass-coated aspherical lenses. A main control board and a power supply unit are provided inside.
[0033] The main control board communicates with the acquisition host through the network unit, and transmits the information obtained by the grading monitoring terminal taking pictures to the acquisition host.
[0034] The main control board is built in with an LWIP program to configure the parameters of the grading monitoring terminal at the site of the tobacco leaf workstation.
[0035] The grading monitoring terminal can realize near-field photographing, and can truly restore both the whole and details of the tobacco leaves, and the image has no distortion. The support and processing ability of the main control board for high-pixel camera data can process the data output by the camera at high speed, making the image details delicate, clear and real, with less image interference and noise, and high imaging quality; the network unit provides support for the transmission of network data information. The control system of the tobacco leaf grading monitoring terminal uses this functional module to read acquisition status information, tobacco basket information, etc. from other devices on the network, such as the acquisition host and the overweigh integrated machine.
[0036] The acquisition host receives data such as the image, grade, and weight of the tobacco basket tobacco leaves, and saves them in the database for filing; the POE interface can obtain electric energy from the network cable and convert the electric energy on the network into the voltage required for the normal operation of each functional unit inside the tobacco leaf grading monitoring terminal.
[0037] The tobacco leaf purchasing work at the tobacco leaf workstation is relatively heavy, and there are assessments on the completion of daily purchasing volumes. This application has stable and reliable working performance, fast data processing speed, can handle relatively complex work tasks, ensure the normal progress of daily tobacco leaf purchasing work, and the work process is fully automatic without manual intervention and requires little daily maintenance.
[0038] The network unit communicates with the remote purchasing host and the weighing integrated machine through a wired network. On the one hand, it provides electrical energy for the tobacco leaf grading monitoring terminal itself through the network. On the other hand, the network has good reliability and strong anti-interference ability, adapting to the seasonal work requirements of the tobacco leaf workstation and the relatively harsh environment requirements of the tobacco leaf workstation involving agricultural products and various strong electromagnetic interference power equipment.
[0039] The POE interface takes power from the network cable and converts the electrical energy into the voltage required for the grading monitoring terminal to work. The POE interface includes parts such as an EMC function unit, a voltage positive and negative polarity detection function unit, an overvoltage protection function unit, an overcurrent protection function unit, and a voltage conversion function unit. The EMC function unit is composed of an X capacitor, a Y capacitor, a common mode suppression inductor, a differential mode inductor, etc., and can filter and process the electromagnetic interference signals crosstalking through the network cable, so that the power supply entering the device internal is stable and interference-free, ensuring the working reliability of the tobacco leaf grading monitoring terminal; the voltage positive and negative polarity detection function unit is completed through the diode bridge circuit connected in the circuit. If the POE device uses special power supply or the wiring is incorrect, the voltage positive and negative polarity detection function unit can correct it, so that the subsequent circuit can still obtain correct and normal power supply and will not damage the device itself due to external incorrect wiring operations.
[0040] Using the POE interface to connect the device to the network and being able to obtain the electrical energy required for the normal operation of the tobacco leaf grading monitoring terminal itself. The POE interface combines the functions of networking and power supply. Through a dedicated circuit connection method and a dedicated POE switch, network data can be transmitted and electrical energy can be provided simultaneously on the same network interface, which greatly facilitates the use and reduces the workload of on-site wiring.
[0041] The tobacco leaf grading monitoring terminal uses a low-light high-definition camera, which adapts to the environment with insufficient illumination inside the purchasing area of the tobacco leaf workstation and can still obtain clear images under an ambient light intensity as low as 0.1 Lux. An imaging CMOS chip with a signal-to-noise ratio as high as 54 dB is used inside, and the resolution reaches 50 million pixels. The photos of the tobacco leaves in the tobacco basket taken have accurate detail restoration, few noise points, and vivid images.
[0042] Multiple groups of aspherical structured glass lenses are used. After the lenses are processed by the coating process, the light transmittance and the consistency of light refraction are greatly enhanced, making the image projected onto the surface of the CMOS imaging chip clearer and brighter.
[0043] The main control board runs the Android system, is equipped with a sensor interface that can process up to 64 million pixels in real time, and has a hardware imaging accelerator in low-light environments to ensure high-quality images.
[0044] The grading monitoring terminal accesses the local area network using a fixed IP method, adapts to the management regulations requirements of the tobacco leaf workstation for the equipment, and is also convenient for the maintenance, repair, and debugging of the grading monitoring terminal during use.
[0045] The grading monitoring terminal starts to work after the tobacco leaf purchase host verifies the identity of the tobacco farmer and starts the tobacco leaf sale of the current tobacco farmer. When no tobacco leaf purchase is in progress, it is in a sleep state to reduce unnecessary power consumption.
[0046] A dedicated APP for tobacco leaf grading monitoring runs inside the grading monitoring terminal, and the APP is communicatively connected to the tobacco leaf purchase host and the database.
[0047] During the tobacco leaf purchase process of the tobacco farmer, when the weighing and batching machine detects a new tobacco basket on the scale and correctly reads the tobacco basket card number, the grade number of the grade plate, and the weight value of the tobacco basket, it sends the tobacco basket information to the tobacco leaf purchase host. The tobacco leaf purchase host sends a photo-taking instruction to the grading monitoring terminal. After the grading monitoring terminal controls the photo-taking, it sends the photo to the database located in the tobacco leaf purchase host for archiving. At the same time, the tobacco leaf purchase host sends the photo to the upper-level server for archiving.
[0048] The internal camera parameter configuration of the grading monitoring terminal has an obvious impact on imaging. Since the overall color of the tobacco leaves is a relatively single golden yellow tone, as Figure 3 shown, the picture is the tobacco leaf form that is relatively close to the real state. If the internal integrated camera parameter configuration of the grading monitoring terminal is in the default "auto white balance" mode, the camera will automatically adjust the color tone towards white (R255 G255 B255) because of the large area of single-color blocks in the image, resulting in the photo taken presenting as Figure 4 shown, with an overall tendency towards dry light yellow and grayish white tones, making the photo taken deviate significantly from the actual object and thus losing the value and significance of photo archiving. In response to this situation, after the internal integrated camera parameter configuration of the grading monitoring terminal is set to the "daylight white balance" mode, the tobacco leaves taken are as Figure 5 shown, presenting a beautiful and mature golden color, truly restoring the form of the tobacco leaves themselves, and being recognized by the person in charge of the tobacco leaf workstation and the relevant assessment person in charge.
[0049] The grading monitoring terminal can take pictures and archive the tobacco leaves in the tobacco baskets sold by tobacco farmers when the weighing and selling are completed, and save them in the acquisition host and the server at the upper level, which is convenient for information traceability, supervision and management, and makes the tobacco leaf selling process of tobacco farmers more open and transparent.
[0050] It also has the functions of high-definition and high-quality imaging and photographing. The details of the tobacco leaf photos taken are clear and the restoration degree is good, which has a high value for information archiving.
[0051] It conducts network communication with the acquisition host and the weighing and integrating machine on the tobacco leaf acquisition line for linkage control. The tobacco leaf grading and photographing function is automatically completed by the program inside it, without manual intervention, reducing the workload of the staff at the tobacco leaf workstation.
[0052] Based on the above method, a tobacco leaf grading monitoring system in this embodiment includes an installation bracket. A grading monitoring terminal is provided on the installation bracket, and a supplementary light is provided outside the grading monitoring terminal. The grading monitoring terminal is used to detect the tobacco baskets of tobacco leaves to be weighed, take high-definition photos of the tobacco leaves in the lower tobacco baskets, and transmit the tobacco leaf photos to the acquisition host through the network unit;
[0053] The tobacco baskets of tobacco leaves to be weighed are placed on the weighing platform of the electronic scale. A weighing and integrating machine is placed on one side of the weighing platform of the electronic scale. An RFID is built in on the side of the weighing and integrating machine close to the tobacco baskets of tobacco leaves to be weighed. There is also a weighing head and a tablet computer inside. The weighing platform of the electronic scale communicates with the weighing head through RFID. The weighing sensor weighs the weight of the tobacco leaves and conveys the tobacco baskets of tobacco leaves to be weighed to the weighing and integrating machine. The weighing and integrating machine transmits it to the acquisition host through the network unit.
[0054] Among them, a POE interface is provided outside the grading monitoring terminal. The internal camera uses multiple glass-coated aspherical lenses, and a main control board and a power supply unit are provided inside.
[0055] The main control board communicates with the acquisition host through the network unit and transmits the information obtained by photographing by the grading monitoring terminal to the acquisition host.
[0056] The main control board is built in with the LWIP program to configure the parameters of the grading monitoring terminal on-site at the tobacco leaf workstation.
[0057] The above specific implementation manners are only specific cases of the present invention. The patent protection scope of the present invention includes but is not limited to the above specific implementation manners. Any technical solution that conforms to the technical solutions described in the above specific implementation manners of the present invention and any appropriate changes or substitutions made by those of ordinary skill in the relevant technical field shall fall within the patent protection scope of the present invention.
[0058] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
