Tobacco grade keyboard input method

Abstract

The invention discloses a tobacco grade keyboard input method. A keyboard comprises a button matrix, a single chip microcomputer, a display and a communication interface, wherein the button matrix is a matrix with four rows and seven columns, buttons of the button matrix include direct definition buttons and additional definition buttons, the direct definition buttons include following buttons: upper impure, upper slightly green, upper twisted, upper orange, middle lower impure, middle slightly three, middle twisted, middle orange, fully mature, lower slightly two, lower twisted, lower orange, smooth, upper reddish brown, undergrade and bluish yellow, and the additional definition buttons comprise four digital buttons: button 1, button 2, button 3 and button 4. By the tobacco grade keyboard input method, input of tobacco grade information can be completed only by operating the buttons for one time or two times, so that the tobacco grade information can be input into a computer system quickly, effectively and accurately, and economic loss caused by input of noneffective grades or wrong grades is avoided.

Description

technical field [0001] The invention relates to a tobacco leaf grade input method, in particular to an accurate, simple and quick tobacco leaf grade keyboard input method. Background technique [0002] According to the "National Standard of the People's Republic of China" GB2635-92 "Cured Tobacco", flue-cured tobacco is divided into 42 grades, and the definition of grade division is as follows: [0003] class ID grade code grade name color parts wait group 1 C1F Nakajuichi F-orange C-Central premium smoke Positive group 2 C2F Nakajuji F-orange C-Central premium smoke Positive group 3 C3F Zhongjusan F-orange C-Central premium smoke Positive group 4 C1L Zhong Ningyi L-Lemon Yellow C-Central premium smoke Positive group 5 C2L middle lemon L-Lemon Yellow C-Central premium smoke Positive group ...

AI Technical Summary

Problems solved by technology

[0011] In the first method, the grade can be input through the character input keyboard provided by the computer. According to the difference in the number of grade characters, the input and grade confirmation of the tobacco leaf grade can be completed by inputting 2-4 characters, but due to the combination of input characters Arbitrary, the input bit error rate will be very high. In the actual use process, if the user is not familiar with the coding of the grade, it is likely to cause an invalid grade or a wrong grade input, resulting in a deviation in the determination of the tobacco grade and directly causing economic losses.

[0012] In the second method, since the selectable grades are all fixedly displayed by the system, there is no problem of input errors. However, due to the large number of 42 grades, it takes more time to browse the interface to search when selecting a certain grade Corresponding grades, and the grade code arrangement is relatively similar, it may cause wrong selection due to visual fatigue and other reasons during long-term repeated operation selection, resulting in serious consequences

[0013] However, in the actual tobacco leaf grade confirmation work, most of the people involved in the work are agricultural population, who know little about information technology, and it is difficult to require them to maintain high accuracy in complex human-computer interaction operations. It is a major contradiction in the process of agricultural production informatization
