Abstract

The invention discloses an optical communication transmitting power adjustable circuit, which is applied to an optical communication sensor of the Ethernet, and comprises a difference-to-single-ended circuit, a light transmitting tube, an energy storage inductor, a current modulation circuit, a current collection circuit and a current monitoring circuit, and is characterized in that the difference-to-single-ended circuit converts a difference signal in the Ethernet into a single-ended signal, and transmits the single-ended signal to the light transmitting tube; the light transmitting tube converts a single-end signal into a light signal, the current collection circuit acquires a current value of the light transmitting tube and sends the current value to the current monitoring circuit, the current monitoring circuit adjusts the current modulation circuit according to the current value so as to adjust the energy storage inductor, the energy storage inductor outputs a stored current to the light transmitting tube, and the input current of the light transmitting tube is adjusted. Therefore, the transmitting power of the light transmitting tube is adjusted, the function of adjusting the transmitting power of the light transmitting tube is realized, and the consistency and stability of short-distance and long-distance data transmission of optical communication are ensured.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to an optical communication transmission power adjustable circuit. Background technique [0002] Optical communication sensors are often used for straight-line data transmission between AGVs. Due to the requirements of industrial development and the complex and changeable factory environment, the requirements for wireless communication transmission data volume are getting higher and higher, and the requirements for optical communication transmission distance are getting farther and farther. , the emission power requirements of optical communication sensors are increasing. [0003] In the prior art, the transmission distance of traditional optical communication sensors has certain requirements, and the emitted light of the optical communication sensors is realized by using modulated infrared light. The transmission power of traditional optical communication sensors is ...
