基于CO_2浓度控制的自动补光设备

Automatic light compensation equipment based on CO_2 concentration control

全自动智能温室中已有自动控制设备只能孤立地调节各种农作物生长所需的环境参数。设计了基于CO2浓度控制自动补光设备,包括CO2浓度传感器、信号放大器、电压比较器、单片机、光源驱动电路、声光超限报警电路。通过单片机检测由CO2浓度传感器传来的检测信号,单片机开启光源对植物进行补光,使大棚内的光照可以长期维护于最佳状态。这种控制方式结构简单、可靠、成本低、实用性强。

Environmental parameters for the growth of crops can only be adjusted independently in the current automatic intelligent control equipment. Here we design light compensation equipment based on CO2 concentration control, and the system includes CO2 concentration sensor, signal amplifier, voltage comparators , computer, light-driven circuits and sound and light limit alarm circuit. Output of the CO2 concentration sensor can be detected by computer and then it determines if the light should be compensate to keep the light in the greenhouse is optimal. The control structure is simple, reliable, practical and with lower cost.
