Bar code with answer-choosing function and application of bar code

Abstract

The invention discloses a bar code with an answer-choosing function and application of the bar code and belongs to the field of data acquisition, examination, printing, bar codes and the like. The bar code comprises a start character, question number codes, a separation mark, an answer-choosing box code and a stop character. Currently, answer-choosing data entered manually are low in efficiency and prone to mistakes; if a cursor card reader is adopted to read or question serial numbers and the answer-choosing data are acquired by image processing after scanning of a scanner, professional card reading or scanning equipment is needed, and answer sheets and questionnaires are needed to be printed highly precisely, so that inconvenience is brought to use, cost is high and promotion is difficult. The bar code is characterized in that a combination of the question serial numbers and the answer-choosing box code is adopted, and a corresponding bar code set is printed for each question; when an answer is chosen, a choosing box of the chosen answer is fully filled; during data acquisition, all the question serial numbers and the answer-choosing data can be acquired in a machine-readable manner by adopting a bar code scanner; therefore, the bar code is easy and convenient to use and rapid and accurate, the answer sheets or the questionnaires are low in printing requirements, wide in using range and convenient to promote.

Description

technical field [0001] The invention discloses a bar code with the function of answering questions and its application. In particular, it is composed of the serial number code of the question and answer question and the code of the optional answer box that can be filled manually. The bar code of the answer data and its application. Involves data collection, information consultation statistics, written examinations, printing, bar codes and other fields related to selective answers. Background technique [0002] For a quiz question, choosing one or more answers to answer in the given multiple answers is almost everyone's experience.

Problems solved by technology

One is manual input, although it has been widely used, the disadvantage is low efficiency and error-prone

The second is to use a graphic scanner to scan and input the image of the answer sheet or answer sheet, and the graphic processing software realizes the identification of the selected answer mark and completes the data input. This data collection method is efficient, but it needs a graphic scanner to image Scanning, at the same time, it is necessary to print higher-precision image reference points and optional answer marks, and the bit error rate is relatively high, which is inconvenient to promote

The third is to use a special cursor card reader to read the manually filled answer box to realize data input, such as the answer sheet and cursor card reading system used in the current domestic college entrance examination. This method has a large amount of data collection, high efficiency and low error rate. Low, but requires special cursor card reading equipment, and also needs to print answer sheets with high accuracy, and for different industries, it is also necessary to professionally produce special optional answer sheets in different formats, which makes the application cost high and inconvenient to use. Difficult to promote on a large scale
