The course of work of present embodiment is as follows:
The circulation of system water, aeration and sterilization control procedure:
The level condition of LT1 liquid level sensor reflection RA1 reactor is when low level and a high position are connected simultaneously, at X0 and the X of PLC
1, when input end all is high level, show that this reactor is full, through PL output terminal Y
0Engage relay J1 opens 1# and promotes water pump P 1, all disconnects X to a LT1 liquid level sensor high position and low level
1And X
0When all being low level, show that this reactor is discontented, disconnect relay J 1, stop 1# and promote water pump P 1, if then keep original state when having only low level to connect through PLC output terminal Y0.After the LT1 liquid level sensor is being delayed time certain hour, also there is not actuating signal for the second time, show that this system's use is in light load, system drives relay J 23 by Y15 will transfer system's aerator to the intermittent mode operation by continuously-running duty, make system ensure the demand of each microbial activity.The level condition of LT2 liquid level sensor reflection RA4 reactor controls 2 equally
#The start and stop of water pump P 2 have so just constituted the water cycle of wash-down water.The level condition of LT3 liquid level sensor reflection elevated tank, when high-order and low level contact all disconnect, X
5And X
4When all being in low level, PLC drives Y
2Engage relay J3 opens moisturizing solenoid valve EC1, to the elevated tank moisturizing, and when LT3 liquid level sensor low level and a high position are all connected, the X of PLC
5And X
4When all being in high level, PLC disconnects relay J 3, stops to the elevated tank moisturizing.LT6 liquid level sensor high signal connection signal is delivered to the X of PLC
BDuring input end, showing has water to flow through, Y
5Make relay J 5 actions open ultraviolet disinfecting flowing water is carried out disinfection, and time-delay, be killed to guarantee most bacterium of flowing through water.By realizing the operational mode of above automatic adjustment system, keep system stability, make the effect of processing remain at same level, reach water saving, purpose of energy saving simultaneously.
The temperature constant control procedure of reactor: the temperature conditions of TT1 temperature sensor reflection RA1 reactor, signal is from X
EInput end enters PLC, after comparing through the A/D conversion and with setting numerical value (as 30 ℃), and when the RA1 reactor temperature is lower than setting numerical value, Y
8Make relay J 10 actions, connect RA1 reactor internal heater and begin heating.When heating in the RA1 reactor surpasses setting numerical value, the Y of PLC
8Relay J 10 is disconnected, promptly stop heater heats, thereby realize the thermostatic control of RA1 reactor.Equally, TT2 temperature sensing management the well heater of RA2 reactor, realizes the thermostatic control of RA2 reactor.
Control procedure between the lavatory: the signal reflection people of infrared sensor goes into the particular location behind the lavatory.When between the 1# lavatory people being arranged in front of the door, infrared sensor IRT9 will have people's signal to deliver to the X of PLC
18, make relay J 22 actions in Y1A output, connect door motor and open the door, treat that the people enters after, close the door and lock, avoided second people to go into the lavatory.The signal of human inductor MT1 is delivered to X
CInput end, the Y of PLC
6Output makes relay J 8 actions, the operation of opening vent fan, " people is arranged " pilot lamp and voice suggestion and background music between the 1# lavatory.When human inductor MT1 induced signal disappears, the Y of PLC
6Disconnect relay, stop the operation of vent fan, " people is arranged " pilot lamp and voice suggestion and background music.As the other infrared sensor IRT1 of w.c.pan, will there be people's signal to deliver to the X of PLC
10, and when leaving after an action of the bowels, Y
AJust drive relay J 12, opens solenoid valve EC3 realizes water flushing w.c.pan.Equally at the other infrared sensor IRT2 of urinal, will there be people's signal to deliver to the X of PLC
11, Y
BDrive relay J 13 and send a brief burst, urinal is drenched, when treating that the people leaves after an action of the bowels, Y
BDrive relay J 13 again and send a bath pulse, opens solenoid valve EC4 realizes the water flushing urinal.Equally, washing one's hands or drying infrared sensor is when staff is arranged, and opens corresponding solenoid valve or hand dryer immediately.When human desires goes out the lavatory, need go out that to leave be by infrared sensor IRT10 in the door, with the signal input X that monitors
19, also make the Y1A output of PLC make relay J 22 actions, unblank and will connect door motor again and realize opening the door for the second time, be convenient to the people and leave.Thereby the automatic control function of complete noncontact between the realization lavatory.When the colour of sky is secretly imported the X1C of PLC to light sensor GT to a certain degree with signal, at Y
17Make relay J 25 connect illuminating lamp LG between lavatories and since during 0 o'clock to 5 o'clock the end user seldom, illuminating lamp LG still is in closed condition, to realize using electricity wisely.
The remote monitoring of system and the implementation procedure of warning: the RS232 interface of PLC is linked to each other with modulator-demodular unit, utilize telephone line (or network line) to link to each other, form a whole network with office terminal (modulator-demodular unit, computer).Can be with communication network being kept at system's service data of tens days of continuous recording in the internal memory, comprise service data every day: number of run and per a few hours of going into lavatory number of times, lift pump are write down the once thermograph of two reactors, are sent on the server of operation control.Also network system can be formed in some similar lavatories, carry out the unified management of concentrating, realize the remote monitoring of supvr, understand full detail this system.By lavatory Unified coding record product operation conditions, be convenient to unified management.Operation troubles is reported to the police: alarm, is dealt on supvr's mobile phone by telephone wire to modulator-demodular unit with the RS232 port of intermittent mode by controller again.Make the supvr in the very first time, obtain situation, the tissue maintenance.Can be sent between all lavatories receiving common information in the network.
