浇灌是弥补自然降水在数目上的不足与时空上的不均，保证适时适量地满足作物生长所需要水分的重要措施。以往的农田浇灌，很多没有配套完整的浇灌系统，注水时只能采用大水漫灌或人工洒水。不但造成水的浪费，而且往往由于不能及时注水、过量注水或注水不足，难以控制水均匀度，对植物的正常生长产生不利影响。我国事一个水资源短缺，水旱灾难频繁的国家。固然水资源的总量居*六位，但是人均占有量约为世界人均水量的1/4，排在世界110位，已被联合国列为13个贫水国家之一，同时，我国水资源的分布很不均匀，有些地区的人均占有量甚至低于世界zui贫水的国家埃及和以色列的水平。我国农业用水量约为总用水量的80%，农业浇灌用水的利用率普遍低下，水的利用率仅为45%，而水资源利用率高的国家已达70%～80%。建立农田节水浇灌的自动化系统，采用高效的注水方式已势在必行。一方面可以集中治理，加强控制;一方面可以按时按需定量供水，严格控制浇灌用水量，达到节水用水目的，另一方面，可以通过自动量测设备，实施精确计量，为按方收费提供依据，促进用水观念更新，为农业生产和人民生活带来巨大的社会效益和经济利益。笔者利用组态软件作为开发平台，开发的农田节水浇灌自动控制系统，已在江苏省泰兴市农业科学研究所节水浇灌示范区得到应用。

         2 节水浇灌自动化控制系统的总体结构

          泰兴市农科所节水浇灌示范区的130亩土地，主要由固定喷灌区，大蓬滴灌区，露地微灌区，草坪喷灌区，低压管道输水浇灌区等部分组成，主要采用滴灌、喷灌、微喷灌和低压管道输水浇灌四种浇灌方式。整个灌区采用自动控制系统，在分干管的放水孔口设置电磁阀和信号收发设备，通过电缆传输到泵房内的控制中心，控制中心根据需水的孔口数目确定打开电磁阀的个数，自动或手动开机浇灌。由泵站出水口沿浇灌区设主干管，主干管沿线再设分干管，分干管上共设有36个给水口，由电磁阀控制后连接支管，每个给水口设置用户给水信号开关一只，当用户需要供水时，按动信号开关，控制中心就会有相应的声光报警提示，控制中心可以远程控制水泵和相应的电磁阀，实现供水，当达到预定的浇灌量水量时，可以自动停泵或封闭电磁阀。控制系统主要是利用PC机远程控制一台水泵、四台加压泵以及36个电磁阀来实现各种浇灌方式。整个控制系统由3个现场控制单元，每个现场控制单元由继电器输出模块，数字量输进模块，开关电源，控制电源等组成，根据系统要求，本系统采用每十六个控制量由一个现场控制单元控制。节水浇灌自动化控制系统的总体结构如图1所示。
