Abstract

The invention provides a test system based on visible light communication; the test system comprises a test device based on visible light communication, a first visible light communication module, a first light source module, a first light reception module, and a terminal; the test device is used for forming subject information and sending the subject information to the first visible light communication module; the first visible light communication module is used for modulating the subject information into a first drive electric signal, and outputting the first drive electric signal to the input end of the first light source module; the first light source module is driven by the first drive electric signal so as to emit visible light signals carrying the subject information. Students download the test subjects through the internet in the prior art and can use the network to search for answers; the test system and method based on visible light communication can solve said problems, arehigh in safety, and can transmit test subjects without using the internet.

Description

technical field [0001] The present invention relates to the field of education, in particular, to an examination system and method based on visible light communication. Background technique [0002] Paperless exams can save exam resources, standardize exam management, and facilitate candidates to take exams. It is becoming a trend. However, the paperless test needs to connect to the Internet to download the test questions through WiFi or mobile communication network, and the network security requirements are high, and a little carelessness may cause leakage of the test questions. Candidates can look up answers online through WiFi or mobile communication networks, which affects the fairness of the exam. [0003] For the problem in the above-mentioned prior art of connecting to the Internet to download examination questions through WiFi or a mobile communication network, no effective solution has been proposed yet. Contents of the invention [0004] The present invention a...
