Abstract

The invention discloses an online learning method based on visible light communication. Downlink: a network receiving and sending module of a visible light signal receiving/sending device connects theInternet to obtain network information, the network information is sent to an LED driving module after being encoded and modulated, the LED driving module drives the on and off of a corresponding LEDlamp of an LED transmitting array according to the sizes of levels, the LED lamp emits yellow light, and illumination is realized while the signal is transmitted; after a light signal detection module of a mobile learning terminal detects a yellow light signal, a signal processing module converts the yellow light signal into a voltage signal and processes the voltage signal, then the original information is restored by a signal demodulation module and a signal decoding module to be obtained by the mobile learning terminal; and an uplink signal is transmitted by the mobile learning terminal tothe visible light signal receiving/sending device through green light in the same way. A mobile monitoring terminal obtains network surfing record and setting network access permissions. The invention further discloses a system for implementing the method.

Description

technical field [0001] The invention relates to the field of online learning, in particular to an online learning method based on visible light communication and a system for implementing the method. Background technique [0002] With the widespread popularity of mobile terminals, Internet addiction is becoming an increasingly serious problem. Teenagers are weak in resisting the temptation of the Internet, and a large number of learning resources and information must be obtained through the Internet. [0003] At present, there are two main solutions to green Internet access: 1. Install software such as "Grey Box" and "Green Internet Manager" on children's mobile terminals. Guide children to surf the Internet greenly; 2. Telecom operators use servers to provide green Internet surfing services for users in need. When a user accesses the Internet, it will be analyzed by the blocking servers installed in various regions, and if it matches the data in the database, the harmful ...
