Think single-chip microcomputer, PLC or other can play the electronic devices and components of phase same-action.
Present invention additionally comprises a kind of total surplus line oxide real-time detection method, the method comprises the following steps:
The first step, draws water sample: under the control of the control unit, water pump action, and water intaking valve 5 is opened, and water pump is automatic
Drawing water sample, the water sample drawn is by water intaking valve 5 automatically in the transparent tube of sensing chamber, and control unit is to regulation valve 6 simultaneously
It is automatically adjusted, it is achieved that the flow of water sample is controlled, according to the flow-control of water sample in fetch water number of times and the regulation valve 6 of water pump,
Control unit can calculate the water yield flowed in transparent tube automatically, thus controls the amount of the water sample pumped into, and be automatically drained out or mend
Foot water sample, until rated value, additionally also ensure that the stationary flow in transparent tube and fixed total amount.Meanwhile, photelectric receiver
The detection light change by transparent tube that 16 monitor and detection room sample Level Detection light sources II 12 send, control unit passes through photoelectricity
The feedback signal of receptor 16 determines the amount injecting water sample.
Second step, adds reagent: under the control of the control unit, laxative pump 10 action, laxative pump 10 is in the control of program
Automatically drawing quantitative detectable in medicine bottle 2 down, the amount of reagent is by programme-control, and detectable is added in transparent tube
Detection water sample in.
3rd step, result detects: after adding detectable, and detectable reacts, in course of reaction with detection water sample
The color of detection water sample changes, and the detection light that sensing chamber's sample color detection light source I 11 sends changes the most therewith, light
The detection light change that electricity receptor 16 monitor and detection room sample color detection light source I 11 sends, and feedback signal is sent to control
Unit processed, thus obtain the total surplus oxide content value of water sample.After obtaining measurement result, outlet valve 7 is opened reacted
Water sample is discharged.
4th step, pipeline-cleaning and dredging: under the control of the control unit, laxative pump 10 regular working, thus periodically from
Medicine bottle draws medicament and enters reative cell 15, then automatically control opening of outlet valve 7, reagent is discharged from outlet pipe, from
And reative cell and outlet valve system are carried out, prevent medicament Crystallization Plugging pipeline.Pipeline blockage is caused owing to condensing crystallization
The main component that medicine is medicament, and this medicament is dissolved in water, so whole system can be entered by system by drawing reagent
Row cleans, thus keeps pipeline unimpeded.
During above-mentioned detection process and pipeline-cleaning, the liquid level in medicine bottle 2 can be monitored by control system the most automatically,
When liquid level is less than threshold, audible and visible alarm can be sent and remind operator to add reagent.Medicine bottle level monitoring method can use such as
Lower two kinds of methods, one of which monitoring method is:
Medicine bottle Level Detection light source I 208, medicine bottle Level Detection light source II 207 and medicine bottle Level Detection light source N206 are to medicine
Bottle 2 sends the detection light of specific wavelength, and its wavelength is 450-589nm, medicine bottle Level Detection photelectric receiver I 201, medicine bottle liquid
Position detection photelectric receiver II 202 and medicine bottle Level Detection photelectric receiver N203 be respectively medicine bottle Level Detection light source I 208,
The photelectric receiver that medicine bottle Level Detection light source II 207 is corresponding with medicine bottle Level Detection light source N206.Along with detecting system works
During medicament draw use, the liquid level of ampoule will be gradually reduced, and after liquid level drops to a certain degree, then can cause medicine
Bottle Level Detection photelectric receiver I 201, medicine bottle Level Detection photelectric receiver II 202 and medicine bottle Level Detection photelectric receiver
N203 sends signal intensity respectively, when liquid level be reduced to medicine bottle Level Detection photelectric receiver I 201 send signal when, then
System judges that liquid level is too low, sends sound and light alarm and adds medicament with prompting operator.
The second detection method is: medicament is loaded in medicine bottle by operator, then defeated to control unit by guidance panel
Entering the agent capacity of current medicine bottle, starting device enters fully automatic working state, and control unit starts to calculate current agent capacity
The number of times that can use, when the number of times that equipment draws medicament reaches the maximum that control unit calculates when, system can send
Sound and light alarm, to point out operator to add medicament.After adding medicament, operator again adds medicament and inputs on guidance panel
Pharmaceutical quantities, starting device enters fully automatic working state, and control unit meeting repeat the above steps, to reach without operator's moment
Purpose on duty.
