4、个模块中 釆用AT89C51单芯片作为下位机，RS485用于上位机与所有AT89C51通信，然 后采集，处理和控制温室参数。每个功能模块电气完全隔离，结点上的任何故障都 不会对其他模块产生任何影响。系统通过每个监控模块分别收集环境信息，并将其 发送到主机PC,在PC配置控制系统中，将获取的参数与设置值进行比较，然后根 据不同生长阶段作物的各种专家智能模糊控制系统，通过模糊控制指令对环境温 度，湿度，CO2浓度，土壤含水量给出相应的操作说明或报警。该系统适用于秦皇岛农村温室，通常在温室内靠近东西端1/4,距北半部中部 （湿帘附近）和南部一半（风扇附近），设置空气温湿度模块，二氧化碳浓度和土 壤含

5、水量模块，根据实际情况，在温室中部添加土壤含水量模块；在主入口高度为 1.5米，设置水箱，根据需要设置滴管的螺线管，并根据土壤含水量模块进行控制； PC放置在温室的主入口。硬件设计在分布式数据采集和控制系统中，山于微控制单元在数据存储方面受到限制， 计算复杂功能较慢，所以釆用PC机，系统采用主从模块，以PC为主机，将位于 场景中的SCM13系统作为从站。在这种分布式系统中，通信是它的关键。一般来说, PC的串行端口是标准的RS232,传输距离更短。在农业控制系统中，通信距离为 数十米或儿公里，因此RS232 / RS485转换器用于实现PC和SCM之间的通信。为 了减少投资，同时考虑到用户便利

6、性和友好的人机交互，我们采用了高于RS486低 于PIV的低价PC；考虑到配置软件的运行,要求运行内存为64 M以上,硬盘为IOGb 以上。温度和湿度，照度和CO2浓度的控制模块每个控制单元由SCNl传感器，信号处理电路，RS485接口和输出电路组成。 二氧化碳浓度通过传感器测量，基于NDIRWI技术，测量范圉为0-2xl03mol通过 传感器，控制系统，通过数字滤波软件，线性插值和温度补偿，CO2浓度输出为符 合UART协议的数字，然后直接输入到SCMO在温湿度测量中选用基于CMoSenS技术的SHTll新型智能传感器。在SHTl 1 中，温湿度传感器，信号放大电路，A/D转换电路，I2C总
