数字控制系统(Texauto)

TexAuto 控制系统是为纺织空调量身定制的专业自动控制系统。

Beckhoff CX9000 控制器及扩展I/O卡件

Beckhoff EtherCAT 及扩展I/O卡件

其核心控制器采用具备强大运算功能和大容量内存的外形紧凑的德国Beckhoff CX9000 嵌入式PC,结合其最新研发Ethercat总线技术,可实现多套空调室的远程分布式控制,有效地减少了用户在控制器和总线构成上的成本支出。

专业人员依据多年的纺织空调运行经验, 精心设计的控制策略,充分体现在控制器根据外气温湿度,车间回风温湿度及车间温湿度设定值,精确计算出外气焓值, 车间回风焓值, 基准露点及露点焓值, 经比较后控制器在自由冷却 /自由冷却+机械冷却/机械冷却工作模式中做出合理选择,以期最大限度的节省用户的能源消耗。控制器以串级调节PID算法控制喷淋室出口露点温度, 实现对车间温度的稳定控制。控制器以PID分程算法调节喷淋出口风阀/二次回风风阀开度及喷淋水泵转速对车间湿度进行控制,获得了极佳的控制精度。

为纺织空调专业开发的上位机监控软件TexView,可灵活地安装在数量不受限制的以Windows作为操作系统的PC机上, 通过普通以太网与CX9000控制器相连,可显示空调流程,各运行参数的实时或历史数据, 报表, 趋势, 报警记录,对其打印, 并提供不同用户级别完成相应设定/操作的人机界面, 在该电脑中可以记录、存储各个时间段的各种测试值,利于技术人员对系统性能的分析、判断故障。通过该系统中的报警信号,在设备维修人员帮助的情况下,采取准确的措施。同时在空调参数转季时,只需将电脑中的参数重新设定即可。可以大量节省空调运转、维护工人。数控系统电子式开环,闭环式控制系统。可以为纺织厂空调站提供最优化的控制方式。此系统共分为三部分:现场仪表、子控制站和检测数控数据的主控制站。

Automatic control system
TexAuto: an automatic control system for textile air-conditioner- the most advanced system in China
TexView: a supervisory control software

   Its core controller adapts German Beckhoff CX9000 embedded PC, which has powerful computing capability, large capacity memory, and a compact form. Cooperating with the new Ethercat bussing technique, it realizes remote control on several air-conditioning chambers, which cuts down the cost on controller and bus effectively.

Taking their years of experience as a support, experts elaborate on the control strategy, which ensures the controller to calculate the external air enthalpy, workshop return air enthalpy, benchmark dew point and enthalpy of benchmark dew point, according to external temperature, workshop return air temperature and humidity, and the set value. The controller compares and then chooses proper models from free cooling, free cooling & mechanical cooling, and mechanical cooling, which saves energy to the maximum limit. The controller adapts cascade control PID algorithm to control the dew point temperature at the outlet of the spray chamber, ensuring the stable control on the temperature in workshops. The controller uses PID relay algorithm to adjust spray outlet air valve/the opening of secondary return air valve, and the speed of the spray pump to control the humidity of workshops, all of which hit a high degree of accuracy.

TexView, professional supervisory control software specialized for textile air-conditioner, is able to flexibly install in one or more PCs taking Windows as operating system, and then connects by normal Ethernet to Controller CX9000. The air conditioning process will be visible, and the real-time parameters, historical data, reports, trends, and alarm records are available to be printed and on setting/operating man-machine interface for various user levels respectively.
