基于485网络的蔬菜大棚温湿度控制系统设计
- 随着蔬菜大棚技术的普及,温室大棚数量不断增多,对于蔬菜大棚来说,最重要的一个管理因素是温湿度控制。温湿度太低或太高,都会影响蔬菜的生长,甚至导致蔬菜死亡,所以要将温湿度始终控制在适合蔬菜生长的范围内。传统的温度控制是在温室大棚内部悬挂温度计,工人依据读取的温度值来调节大棚内的温度。如果仅靠人工控制既耗人力,又容易发生差错。现在,随着农业产业规模的提高,对于数量较多的大棚,传统的温度控制措施就显现出很大的局性。为此,在现代化的蔬菜大棚管理中通常有温湿度自动控制系统,以控制蔬菜大棚温度,适应生产需要

基于ARM 与WINCE 的RS485 驱动程序设计
- 随着工业设备控制要求的日益复杂,嵌入式的工业控制系统成为必然趋势。由于RS485 具有良好的抗干扰性、传输距离长和多站能力等优点,在工业控制领域中应用最广泛。为了开发基于ARM9 内核和Windows CE 5.0 系统的RS485 驱动程序,首先给出了硬件电路设计,接着阐述了Windows CE 系统的驱动模型以及中断处理方法;然后详细描述了RS485 驱动程序的具体设计过程,包括驱动程序的结构设计、关键函数设计、驱动程序的注册和加载等。实验结果表明,RS485 驱动程序运行稳定可靠。
CAN与RS485区别
- CAN与RS485区别 CAN总线有如下基本特点 ◎ 废除传统的站地址编码,代之以对通信数据块进行编码,可以多主方式工作; ◎ 采用非破坏性仲裁技术,当两个节点同时向网络上传送数据时,优先级低的节点主动停止数据发送,而优先级高的节点可不受影响继续传输数据,有效避免了总线冲突; ◎ 采用短帧结构,每一帧的有效字节数为8个,数据传输时间短,受干扰的概率低,重新发送的时间短; ◎ 每帧数据都有CRC校验及其他检错措施,保证了数据传输的高可靠性,适于在高干扰环境下使用;
