The pattern design based on PLC fountain
Abstract
In traditional fountain control system design good control circuit， once can’t
change pattern and water spraying time such issues ， the design with Siemens
s7—200 PLC design can adapt to different season， different occasions of hydraulic
requirements the pattern of the fountain system purpose. Figure fountain control
system is the main task of the change of style， water fountain in order to achieve
regular change of the water fountain style purpose. Press the start button, and
fountains device started to work， and press the stop button, fountain control device
to stop working 。 Work by pattern choice fountain way switch and a single
step/continuous switch decision。 When a single step/continuous switch choose single
step， fountain can only choose switch is set according to the pattern, run a cycle way;
When a single step/continuous switch choice， according to the pattern for fountain
switch selector way， operation DuoGe circulation， press the stop button until。
Figure cycle way choice to select a fountain of hydraulic switch pattern, the paper
presents the design of four kinds of water spray pattern cycle。 PLC control system
small volume and powerful function， high reliability， and has a greater flexibility
and expansibility characteristic. PLC control system, and designs fountain not only
realized the automatic conversion pattern fountain of hydraulic style， improve the
reliability of system and security, and， beautification our living environment, make
our life more comfortable and comfortable environment。 So PLC control system has
some of the engineering application and dissemination value.
Key words： PLC control, pattern fountain system
