Description
Technical field:
Fuzzy control system is used the present invention relates to a kind of steel pipe cool water shower is energy saving.
Technical background：
In steel pipe corrosion-proof line production process, it is necessary to which water sprinkler system sprays steel tube surface after steel pipe is by coating line
Water cools down.Pumping for water pump is taken in production process at present to provide water spray required water.But basis is not worked as
The actual temperature of preceding steel tube surface carrys out the accurate size for controlling water, and control process is more extensive, is unfavorable for the utilization of the energy.
At the same time conventional control methods due to the non-linear of water sprinkler system, complexity and polygon so that control difficulty compared with
Greatly, there is very big hysteresis quality.The present invention uses FUZZY ALGORITHMS FOR CONTROL so that faster, control effect is real-time for control response speed
Property greatly reinforces, and can save mass energy.
The content of the invention：
Present invention the shortcomings that being directed to control method described above, steel tube surface temperature value using collection is as judging whether temperature reaches
To desired foundation, using FUZZY ALGORITHMS FOR CONTROL, field experience and experimental data are integrated into controller, realize that steel pipe cools down
The intelligent control of water spray.It is easy with control, the complicated state being well adapted for when steel pipe cool water shower works and acquirement
Good energy-saving effect.
The purpose of the present invention is mainly achieved through the following technical solutions：
In the present invention, temperature sensor signal Acquisition Circuit obtains corresponding voltage signal, is conveyed to PLC chip and becomes numeral
Amount, by judging the temperature level of current steel tube surface compared with default voltage, PLC chip draws the deviation of voltage
And voltage deviation change rate；
In the present invention, PLC calculates corresponding control signal simultaneously by obtained voltage deviation and voltage deviation rate according to fuzzy algorithmic approach
Corresponding frequency converter output frequency is converted into, is conveyed to frequency converter, the water spray variable-frequency motor connected through Frequency Converter Control turns
Speed, so as to fulfill the control to steel tube surface temperature.

To control variable-frequency motor.
As shown in Figure 2：PLC carries out the magnitude of voltage detected and the magnitude of voltage of the steel tube surface temperature transition of technological requirement
Compare；Obtained from corresponding voltage deviation e andVoltage deviation rate ec is obtained, to voltage deviation and voltage deviation rate
Carry out Fuzzy processing.According to actual electric field experimental data and fuzzy algorithmic approach requirement, three fuzzy sons are set to voltage deviation e
Collect and be：Temperature deviation is big, temperature deviation is moderate, temperature deviation is small, voltage deviation rate ec is set three fuzzy subsets as：Temperature
Change is fast, temperature change is moderate, temperature change is small.The output variable v of fuzzy algorithmic approach is set five fuzzy subsets as：Rotating speed is fast
Speed increase, rotating speed is slowly increased, rotating speed is constant, rotating speed slowly declines, rotating speed rapid decrease.
Show that fuzzy control rule is according to field experience and experimental data：
