摘要
设计采用了ARM7内核嵌入式处理器LPC2103,软件采用μC/OS-Ⅱ操作系统;提出了基于GPRS和GPS的嵌入式蔬菜大棚湿度控制系统的硬件结构以及软件设计方法,使用SHT75湿度传感器检测蔬菜大棚内的湿度,设计了GPS、GPRS、湿度检测以及控制电路;使用μC/OS-Ⅱ操作系统进行系统软件多任务管理,设计了4个任务,实现GPS数据获取、GPRS发送信息、湿度检测以及控制功能;实验选取一个种植黄瓜的蔬菜大棚,当湿度高于80%时,开启换气扇,低于70%时,开启水泵,实现了湿度的自动控制。
The design uses ARM7 core embedded processor LPC2103 and μC/OS-Ⅱ operation system. Hardware structure and software relation method of the vegetable greenhouse supervisory control system is proposed. SHTT5 sensor is used to detect humidity signal. μC/OS-Ⅱ operation system is used to manage multi--task software. Four tasks which include initial task, GPS data deceive, GPRS data transmit and humidity supervisory control are used in order to realize the unction of the system. Every task＇ s relation method is given. When cucumber greenhouse humidity is above 80%, the ventilator is work. When humidity is below 70%, the water pump is work. The greenhouse humidity is controlled automatically.
