The invention discloses a coding method and system for simultaneously realizing light intensity adjustment and optical communication, and belongs to the technical field of plant factories. According to the method, the target PWM wave code and the data acquisition instruction frame are subjected to secondary coding, and then light formula detection, dimming symbol reinsertion and optical communication secondary coding after dimming symbol adjustment are performed on the light intensity information of the LED lamp subjected to secondary coding, so that the light intensity of the LED lamp can be controlled, the ambient light intensity is consistent with the target light intensity, and the light intensity of the LED lamp can be controlled. And modulation of an environmental parameter acquisition optical communication instruction can be completed through LED light, so that the functions of plant growth light intensity adjustment and issuing of the environmental parameter acquisition optical communication instructi
