Description

Technical Field

[0001] This utility model relates to the field of tobacco farmer verification terminal technology, specifically to a tobacco farmer verification terminal device applied to a tobacco leaf processing section grading production line. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] The tobacco farmer verification terminal is a component of the segmented grading production line system. Its functions are: ① to verify tobacco farmer identity using facial recognition; ② to initiate tobacco leaf delivery; ③ to display the current delivery information of the tobacco farmer; and ④ to terminate the current tobacco farmer's tobacco leaf delivery.

[0004] The main workflow of the tobacco farmer verification terminal is as follows:

[0005] 1. Tobacco farmers use facial recognition for identity verification.

[0006] After the tobacco farmer verification terminal establishes a network communication connection with the purchasing host, the tobacco farmer can bring their ID card to the face recognition column for face verification. After successful identity verification, the tobacco leaf delivery can begin.

[0007] 2. Begin the sale of tobacco leaves.

[0008] After the tobacco farmer completes facial recognition verification, the LCD screen of the verification terminal will display the farmer's information, including name, ID number, current delivery status, and remaining delivery quantity. Other information, such as the farmer currently delivering to another purchasing line or insufficient remaining delivery quantity, will also be displayed on the LCD screen.

[0009] The grader checks the tobacco farmer's identity verification information displayed on the LCD screen of the tobacco farmer verification terminal, confirms that the farmer is correct, and clicks the "Start Sale" touch button on the LCD screen.

[0010] 3. Displays the current sales information of tobacco farmers.

[0011] After the tobacco leaves from the tobacco farmers are graded by graders on a modular assembly line, they are packed into baskets and then automatically conveyed to the weighing station for weighing.

[0012] After the tobacco baskets have been weighed normally, information such as weight, grade, and price will be displayed on the LCD screen of the tobacco farmer's verification terminal.

[0013] If the tobacco baskets fail to weigh properly, such as when "tobacco basket card not entered" or "tobacco farmer's remaining quantity is insufficient," the LCD screen on the tobacco farmer verification terminal will display a message prompting staff to handle the issue promptly.

[0014] 4. End the current tobacco leaf delivery for tobacco farmers.

[0015] After the tobacco farmer finished selling his tobacco leaves, the grader clicked the "Submit" button on the LCD screen of the farmer's verification terminal. This concluded the tobacco farmer's tobacco leaf sales process for that particular farmer.

[0016] The tobacco farmer verification terminal is indispensable in the tobacco leaf delivery process. How to improve the performance and ease of use of the tobacco farmer verification terminal through equipment improvement, and improve the efficiency of tobacco leaf delivery, is a problem that needs to be solved.

[0064] The date clock unit circuit includes components such as resistor R94, resistor R95, capacitor C15, backup battery, watch-specific crystal oscillator Y2, chip U8, and diode D15. A 3V3 power supply powers chip U8 through diode D15. During normal power-on operation, chip U8 uses the voltage after passing through the diode from the 3V3 power supply for its operation. After a power outage, chip U8 is powered by backup battery BT1, allowing chip U8 to continue timing and recording the date while the system is not powered on.

[0065] The tobacco farmer verification terminal equipment disclosed in this utility model also includes a power supply adapter, such as...
