摘　　要：光照是植物生长和发育的重要环境因子之一,在植物组织培养过程中,为了更好地利用LED光源对组培室内植物进行补光,节约能源和提高补光效率,设计了一种基于STM32的植物补光调控系统;系统采用STM32作为微控制器,设计植物补光总控中心和补光调控节点电路,补光总控中心通过RS485通信模块与安装在组培室内的多个补光调控节点进行指令和数据的通信,补光调控节点根据补光总控中心的任务指令和补光参数,协调补光调控节点的各个电路模块之间相互工作,实现按时、按量对组培室内的植物进行补光;经过实验测试结果表明,该系统环保、易操作且性能稳定可靠,能够实现补光的同时节约能源,进而减少了组培室的育苗成本,为在植物组培室内实现植物的补光提供参考。Light is one of the important environmental factors for plant growth and development.An STM32 plant light supplement control system is designed in order to make better use of LED light source for plants in tissue culture room,save energy and improve the efficiency of light supplement.STM32 is used as the microcontroller to design the plant light supplement control center and the control nodes.The control center communicates the instructions and data with the multiple light supplement control nodes,installed in the tissue culture room,through the RS485 communication module.According to the instructions and the light-supplementing parameters,control nodes coordinate each module to work with each other,so as to achieve the light supplement on time,on demand and according to quantity.The experimental results show that this system is environmentally friendly,easy to operate,stable and reliable.It can save energy while replenishing light,thus reducing the seedling raising cost of tissue culture room,which is a reference of supplement light in tissue culture indoor plant.
