Abstract
The full automatic water supply system include water pump, water pipeline and accessorys and it features its industrial control microcomputer, frequency- varying speed regulator, pressure sensor and flow sensor, which constitutes one closed loop control system following automatically the set pressure value and controlled based on furry control theory. It has also printer and alarm executing the relative command of industrial control microcomputer. The present invention can optimize water pump operation, reduce its power consumption and turn on and off water pumps in required number, and it can realize unattended operation.
Description
The invention belongs to field of industrial automatic control, specifically is a kind of water supply of fuzzy control and demonstration, warning system.
Advanced at present full automatic water supply system adopts the automatic water supply system of PLC machine control (Chinese patent CN92216500, title: PLC machine control automatic water supply device).The automatic water supply system of PLC machine control comprises: the force value given circuit, pressure transducer, frequency converter, as speed governing, switching command and fault alarm Programmable Logic Controller PLC machine with control element, the switching pump variable frequency that intermediate sensor, A.C. contactor constitute or the main control circuit of power frequency operation.Its control procedure is: the artificial earlier exit of pump force value of setting, this force value is compared with the observed pressure value and is obtained a difference, and the PLC machine is handled this difference, and the frequency of control of conversion device, thereby control the rotating speed of pump motor, reach the purpose of automatic adjustment pressure of supply water and flow.Its weak point is:
1, setup pressure value is artificially to set according to extraneous water situation, can not be from the required pressure of supply water of motion tracking user, and power consumption presses water system to descend to some extent than Huan, but still exists the space of saving not to be utilized.
2, because be artificial adjusting, operative employee's operant level has determined the quality of reduction effect, and people's operative technique has certain difference, and is subjected to the influence of mood etc. bigger, and this has just restricted reduction effect, and manually-operated that What is more may cause the water supply accident.
3, can't realize unattended.
The purpose of this invention is to provide a kind of fuzzy control theory that utilizes can be from the required pressure of supply water of motion tracking user and the automatic control water system of flow, when satisfying user's needs, make water pump operation at high efficiency range, reduce the water pump power consumption to greatest extent, using water wisely simultaneously, and show parameters such as pressure, flow, failure condition instant alarming in real time.
Technical scheme of the present invention is: the exit of pump pressure and the pipe network flow signal of pressure transducer, flow sensor collection are sent to industry controlled micro-computer, after in industry controlled micro-computer, carrying out Fuzzy Calculation, frequency signal is sent to variable-frequence governor, variable-frequence governor changes the out-put supply frequency and then changes the rotating speed of pump motor, adjust pressure of supply water and flow, pressure transducer, flow sensor will collect new pressure and flow signal and be sent to industry controlled micro-computer and begin next cyclic process; To show that printing, alerting signal are sent to printer and warning device; Send the signal of the pump of opening, cut off the water to the automatic switching protection device, after the A.C. contactor action, variable-frequence governor opens, the power failure machine, sends the open and close valve signal to automatic electromagnetic valve.
Utilize fuzzy control theory in industry controlled micro-computer, to realize it is characterized in that from the required pressure of supply water of motion tracking user and the control of the water yield:
1, by collecting the data statistics of operating experience and operation, (fuzzy control theory calculates the method that adopts: fuzzy reasoning method) make the question blank that exit of pump is set desired pressure value through fuzzy control theory calculating, determine the desired pressure value Ps of each time by question blank, and leave in the PRG3 module.
2, detected pressure and flow value, gather by analog quantity load module (AI1-AI3), carry out mould/number conversion through scale module PRG1 and be transported to pressure filtration module PRG9, obtain observed pressure value Pz, Pz and Ps together deliver to comparison module PRG2 and compare, obtain Pc=Ps-Pz, Pc delivered to carry out Fuzzy Calculation among the Fuzzy Calculation module PRG 3 and determine correspondent frequency signal Zc value, the Zc signal is delivered to the analog output module D01-D0n of each pump through scheduler module PRG6, this signal is changed through next step, is transported to variable-frequence governor.
3, detected flow value Qz is gathered by analog quantity load module AI2, carrying out mould/number conversion through scale module PRG1 is transported to flow filtration module PRG4 and shows in display module DISP6 and deliver to scheduler module PRG6 with the Pc value, after in this module, comparing with a water pump of increase or the condition that reduces by a water pump, a water pump of increase or the signal that reduces by a water pump are delivered to D01-D0n and D0 analog output module, after next step conversion, determine the quantity of process pump.
4, the switching value signal that receives is transported to switching value modular converter PRG7 through switching input module DI1-DIn and converts digital signal to, sends into scheduler module PRG6 and participates in reporting to the police, and is transported to display module DISP3 simultaneously and shows.
5, clock module ET1 is used for providing the standard time to other module.
Beneficial effect of the present invention: the present invention has utilized fuzzy control theory, Fuzzy Calculation is carried out in data statistics to operating experience and operation, make in 1 year with changes of seasons, over time exit of pump is set the question blank of desired pressure value in one day, it is very approaching or equal to set this interval of desired pressure value that industry controlled micro-computer control water pump operates in the top hole pressure value all the time, in this running status, compare with the PLC machine water system of artificial setting and operation, operating in when satisfying user's consumption of native system water pump, pump motor may operate at best high efficiency range, reduced the water pump power consumption to greatest extent, because of not needing manual operation, the unfavorable and accident of having avoided human factor to cause; The reception responding device of native system is aut.eq., therefore, can realize unattended.
