With the development of science and technology,the emergence of smart greenhouses,smart greenhouses and plant factories has changed the traditional agricultural cultivation methods.In recent years,the scale of greenhouse cultivation has become larger and larger.This method of planting allows the plant growth environment to be controlled artificially,giving full play to land productivity and increasing yield.The plant light control system combined with computer network technology to regulate the growth environment of plants has theoretical research and practical value.Aiming at the light environment regulation of plants growing in the greenhouse,this paper uses a new light source LED as a supplemental light source,wireless network communication,a simple star topology,and each terminal node and Zigbee coordinator through The wireless communication technology composes a network for data transmission and realizes the establishment of the wireless network.The coordinator and the PC end use the serial communication technology for data transmission.The plant lighting control system based on Zigbee wireless network technology sends the supplementary light control instruction information to the Zigbee coordinator through the serial port on the PC side,and then sends the information to each terminal node through the Zigbee wireless network.The LED light source fill light module is used for regulation.The light sensor module sends the collected light data to the terminal node through the I2 C protocol.The terminal node sends it to the coordinator,and then transmits it to the PC.Check,the user performs the supplementary light operation according to the current light data in the greenhouse to complete the scientific supplementary light.In addition,the layout of the LED light sources is arranged,and two types of LED light source arrays with different layouts are designed,and they are analyzed and compared through formula derivation and simulation experiments.The results show that under the condition that the light source height z is 15 cm,the uniformity of the light intensity in the staggered interval arrangement is better than the uniformly spaced uniform arrangement,which improves the resource utilization rate for modern agricultural cultivation.
