Description
Technical field
This utility model belongs to filter plant field, specifically, relates to the DCS control of a kind of boiler replenishing water pump
System processed.
Background technology
The generation that the major part of China refluxes to avoid boiler spilling water as far as possible, improves small pump work efficiency,
Reducing unnecessary waste of energy, the most effective method controls small pump intermittent water application exactly.According to pot
The practical situation of cylinder, makes an inner room confession system, allows small pump be operated according to a confession system.So
Substantially can accomplish to there is a need to just supply, it is not necessary to just stop, reach purpose that is energy-conservation and that reduce small pump maintenance.
For being exactly when drum water is full between small pump, it is shut off small pump；When water level decreasing certain depth,
It is then turned on small pump and carries out moisturizing.
Between taking at present, the method for system is artificially according to liquid level, determines small pump timing start-up, shuts down
Realize.This method is to small pump start and to be spaced definite proportion really downtime fuzzyyer, blames post workman
The heart is appointed to require the highest.Manually tuning to open control accuracy the highest, person works measures greatly, and small pump work efficiency is not
Height, if cannot avoid flooded conditions in time in addition, it is also possible to accident can be caused to occur.
So, for the technician, it would be highly desirable to the problem of solution is to develop the DCS of a kind of boiler replenishing water pump
Control system, reasonable in design, there is manually and automatically two kinds of control modes, can realize under automated manner
The fully automatic operation of system, by monitoring the ANOMALOUS VARIATIONS of controlled parameter in real time, sends alarm signal, reports to the police
Point out personnel control small pump start and stop on duty etc., it is ensured that production safety, reduce causality loss, reduce electricity
The purpose that can be lost, is suitable to promote.
Summary of the invention
The technical problems to be solved in the utility model is to overcome drawbacks described above, it is provided that a kind of boiler replenishing water pump
DCS control system, reasonable in design, there is manually and automatically two kinds of control modes, permissible under automated manner
Realize the fully automatic operation of system, by monitoring the ANOMALOUS VARIATIONS of controlled parameter in real time, send alarm signal,
Alarm operator on duty controls small pump start and stop etc., it is ensured that production safety, reduces causality loss, reaches fall
The purpose of low electric energy loss, is suitable to promote.
For solving the problems referred to above, this utility model be the technical scheme is that
A kind of DCS control system of boiler replenishing water pump, it is characterised in that: include controller and connect control
Device connects A/D converter, and A/D converter connects the pressure transducer being placed in boiler；Described control
Device connection has keyboard, input control circuit, watchdog circuit, outputting circuit for relay, warning circuit, refers to
Indication lamp circuit and the time relay；Described outputting circuit for relay connects circuit for controlling motor.
As the technical scheme of a kind of optimization, described controller connects manual automatic transfer switch.
As the technical scheme of a kind of optimization, described controller uses AT89C51 single-chip microcomputer.
As the technical scheme of a kind of optimization, described indicator light circuit be connected to a red led and
Green indicating lamp.
Connect as the technical scheme of a kind of optimization, described warning circuit and watchdog circuit and have buzzer siren.
Owing to have employed technique scheme, compared with prior art, this utility model is reasonable in design, has
Manually and automatically two kinds of control modes, can realize the fully automatic operation of system, by reality under automated manner
Time monitor the ANOMALOUS VARIATIONS of controlled parameter, send alarm signal, alarm operator on duty controls small pump and opens
Stop, it is ensured that production safety, reduce causality loss, reduce the purpose of electric energy loss, be suitable to promote.
The utility model is described in further detail with detailed description of the invention below in conjunction with the accompanying drawings simultaneously.
Accompanying drawing explanation
Fig. 1 is the structured flowchart of a kind of embodiment of this utility model.
Detailed description of the invention
Embodiment:
As it is shown in figure 1, the DCS control system of a kind of boiler replenishing water pump, control including controller and connection
Device connects A/D converter, and A/D converter connects the pressure transducer being placed in boiler；Described control
Device connection has keyboard, input control circuit, watchdog circuit, outputting circuit for relay, warning circuit, refers to
Indication lamp circuit and the time relay；Described outputting circuit for relay connects circuit for controlling motor.
Described controller connects manual automatic transfer switch, has manually and automatically two kinds of control modes,
The fully automatic operation of system can be realized under automated manner.
Described controller uses AT89C51 single-chip microcomputer.Described indicator light circuit be connected to one red
Color display lamp and green indicating lamp.Described warning circuit and watchdog circuit connect buzzer siren.
Work process is: is automatically detected the pressure condition of drum by wellhead pressure sensor, then will detect
Analog data be sent to A/D converter, A/D converter be sent to monolithic after being converted to digital signal
Machine, is analyzed contrast by single-chip microcomputer, it is judged that the operating mode of small pump: fill the state that still do not fills, so
After adjusted oil pumper by Intelligent Single-Chip Based and run time and downtime, and by display device display timing
Time and small pump accumulative operation working time；Relay output element uses the time relay and middle relay
Device, (is set as 30s) for the previous period in start and sends alarm signal and have display lamp display small pump
Operation conditions, prompting periphery staff withdraws on-the-spot guarantee safety work.
This utility model is reasonable in design, has manually and automatically two kinds of control modes, permissible under automated manner
Realize the fully automatic operation of system, by monitoring the ANOMALOUS VARIATIONS of controlled parameter in real time, send alarm signal,
Alarm operator on duty controls small pump start and stop etc., it is ensured that production safety, reduces causality loss, reaches fall
The purpose of low electric energy loss, is suitable to promote.
This utility model is not limited to above-mentioned preferred implementation, and anyone should learn at this utility model
Enlightenment under the structure change made, every have with this utility model same or like as technical scheme,
Belong to protection domain of the present utility model.
