As for the humidity, the water electrodes can increasingly high concentrations of easily generated scale, the impact of the effect of steam generated, so in accordance with set procedures, the main control of the controller will work in the host after a certain period of time to open the drainage valve (according to different drainage water cycle settings), ranked out of high concentrations of water, automatically add new water to ensure a good humidifier humidification efficiency, and extend the useful life of the host.

随着加湿的进行，电极罐中的水浓度越来越高，极易产生水垢，影响蒸汽产生效果，因此根据程序设置，主控制控制器将在主机工作一定时间后打开排水阀（可根据不同水质设定排水周期），排掉高浓度的水，自动补充新水，确保加湿器良好的加湿效率以及延长主机使用寿命。

Here is the main content.The control unit of this system use 8031 as the controller of CPU. It can collect the pressure singals of the gasoline tank and adjust the big and small of the fuel vapor pressure, cooperating with steam pressure sensor and electromotion valve.

主要内容有以下几点：(1)测控系统的控制部分是以8031单片机为CPU的控制器，它配合蒸汽压力传感器和电动调节阀完成油箱内信号采集和汽油蒸汽压力调节功能。

The process of powder soution preparation operates each soution tank gade, they are bocked off. it coud assure the best reaction time invariabeness consistency of every soution tank, avoid any direct touch of prefabricated tank iquid storage tank, the automatic contro system ised with eve sensor, to gain the exactitude consistency. When the eve reaches ow, the soenoid vave open, the powder feeding started. Opposite, the eve reaches high, the circe process stop.

干粉溶液制备过程是通过各个溶液槽分级逐步完成的，溶液槽之间隔开，保证每个溶液槽内的最佳反应时间和恒定浓度，避免在预制槽和药液储存槽之间有任何直接通路，自动控制系统与储存槽上的液位控制器相连，一旦液位达到低位，触发进水电磁阀打开，干投机启动，投加量安装水量设定，以获得精确浓度，当液位达到最高点，此循环过程就停止，当然搅拌器还按设定时间继续工作。

With convincing data the intercomparison of the performances on PID control,Fuzzy control and P-Fuzzy-PI control is given.

锅炉汽包水位控制系统由汽包、水位变送器、控制器和给水调节阀组成，如图1所示。

This equipment uses the mesa structure, has the controller, the sensor (electro-optical type, inductance type, color, magnetic induction type), the revolving encoder, the electric motor, the conveyor belt, the air cylinder, the solenoid valve, the direct-current power supply, the air filtration reductor, the programming practice kneading board and so on, the constitution model integration of machinery teaching training installment.

该装置采用台式结构，配有控制器、传感器（光电式、电感式、颜色、磁感应式）、旋转编码器、电动机、输送带、气缸、电磁阀、直流电源、空气过滤减压器、编程练习面板等，构成典型的机电一体化教学训练装置。
