目前高层建筑在各类城市中比比皆是。为了防止意外火灾，高层建筑一般均设有消防专用泵组。但是许多设备都因无专人管理，不能定期试机运行，天长日久就会导致泵体卡死、锈死，所以经常会出现在发生火灾时设备不能充分发挥作用的情况，造成不应有的损失。通常老设备的启动/运行转换控制用的是皮碗真空式定时继电器，其定时时间误差大，橡胶容易老化破损，维护不便。电子式定时继电器也存在类似问题。我们采用OMRON公司的可编程序控制器（PLC）对消防泵组进行控制，实现泵组在备用时定期试运行，消防用水时自动启动。硬件无调整元件，成本低，可靠性高，维护方便。而且可以很容易地根据不同需要进行扩展。这样能够有效地杜绝泵体锈死或消防用水时不能及时加压的事故。
