Problems solved by technology

[0004] However, when the interconnection between two devices is realized through the wireless module, since the wireless module sends data in the form of broadcast, other devices within the communication range of the wireless module can also receive the data, resulting in the existence of the data The possibility of being tampered with, which reduces the security of data transmission, at the same time, the hardware cost of the wireless module is also high

Abstract

The invention discloses a data transmission method based on color light, a sending end device and a receiving end device. The method includes: sending a first color light signal in a directional manner, the first color light signal including a combined color light used to indicate the first color light coding rule; encoding the data to be transmitted according to the first color light coding rule to obtain a second color light The optical signal; the data to be transmitted by the wireless module at least includes the target data to be transmitted; and the second color optical signal of the wireless module is sent directionally.

Description

technical field [0001] The present invention relates to the technical field of optical communication, in particular to a data transmission method based on color light, a sending end device and a receiving end device. Background technique [0002] With the development of the Internet of Things, multiple interconnected devices are widely used in various scenarios. For example, interconnected air conditioners and electric windows are applied to homes. [0003] At present, taking two devices as an example, the interconnection and intercommunication between the two devices is usually realized by setting wireless modules such as Bluetooth and wifi in each device. [0004] However, when the interconnection between two devices is realized through the wireless module, since the wireless module sends data in the form of broadcast, other devices within the communication range of the wireless module can also receive the data, resulting in the existence of the data The possibility of b...
