当某一空调有故障报警产生，其对应的PLC控制器将变为红色或黄色报警，以显示不同程度的警情；
当PLC与上位机软件监控系统间的通讯中断时，该PLC会变暗，以提醒维护人员查看设备连接状况
3.空调监控画面
21
说明：
与人机界面控制功能相似，此画面为空调监控画面，可直观地查看并设定温湿度、风速、风机频率，选择工作模式、季节模式、排风机启停模式，启停风机，设定PID参数、阀门开度、除湿上下限、消排毒时间…
23
根据空调的运转状况，加热、表冷、加湿段的蒸汽、水阀开度都会表现出颜色变化的动态效果
风机扇叶也会根据实际转台呈现出转动的动画效果
初效滤网、中效滤网阻塞时，会以红色警戒色提醒操作人员处理，风机异常会有WARNING红色字样提示操作人员切换至报警记录窗中查看
4.报警画面
24
说明：
此页为报警画面，可在报警记录窗中查看当前报警，及历史报警记录
报警记录窗中的报警信息默认为红色字显示，绿色字代表已解除的警情，报警时间和恢复时间都会被记录，报警值与恢复值、警情处理人员的信息也会被记录下来
报警记录窗右侧为温湿度报警限值设定窗
5.报表画面（实时报表和历史报表）
实时报表
24
说明：
报表查询画面，可查询当前空调运转参数的实时报表，也可以通过设定查询时间段，查询历史数据报表，并进行保存、打印、页面设定等操作
6.趋势曲线画面（实时趋势曲线和历史趋势曲线）
实时趋势曲线
实时趋势曲线画面，可动态添加、删除、隐藏变量曲线，对不同变量的变化趋势进行比较分析
25
历史趋势曲线
历史趋势曲线画面中，可对变量的历史变化趋势，分时分段的进行查看，在趋势曲线显示框下部为曲线数值框，当取样游标点击曲线时，会获取当前变量值，同时变量的最大、最小、平均值在数值框中也有体现
26
7.事件记录画面
说明：
事件记录画面中，普通用户可以进行密码修改的相关操作，管理员可对用户进行添加、删除和密码管理操作；此外，所有成员的登陆、操作信息会被记录下来，有利于管理者对空调控系统的管理
26
六、 结束语
台达HVAC解决方案配合SCADA监控系统的生动展示，使得整体方案无论在功能操作还是画面展示效果方面都得到了客户的认可。网络互连与信息互通
“随着汽车配件产品个性化程度的提高，未来，一条产品线上同时生产多种轮型，快速切换产线将变得十分普遍。由于全球信息的快速交互，以及动态商业模式的形成，许多即时的合作订单将会产生，这也要求轮毂生产线具备快速的应急反应能力。”这些都是刘双勇看在眼里的大势所趋。
刘双勇是侯旭所在的中信戴卡装备工程有限公司的总工程师，他意识到以数字化信息技术和前沿工业软件为基础，制造型企业正在经历一次生产方式的全面革新。因此，中信戴卡不断探索工业生产管理高度集成的可能。
