Abstract
The utility model provides a liquid level automatic control device based on singlechip, including water pump and control unit, control unit includes setting liquid level changer in aqueous to reaching a digital liquid level with liquid level changer signal connection and observing and controling the appearance, the switch and the digital liquid level observing and controlling appearance of water pump are connected, the screen of digit liquid level observing and controlling appearance is double screen LED's liquid level switches screen, the outer glass screen who still is equipped with a protective's whole thickness for 2mm of liquid level switches screen. The utility model has the advantages of: can real -time demonstration liquid level, make things convenient for looking over of staff to can set for the upper and lower limit of change control height wantonly, strengthen digital show with the LCD display change for double screen LED in the display part, convenient on -the -spot staff watches also to have very high luminance under abominable operational environment, be 2mm's glass screen with display screen plus whole thickness, reach instrument board duplicate protection, it is not fragile under abominable operational environment.
Description
Technical field
This utility model relates to Liquid level field, particularly relates to a kind of SCM Based liquid automatic control
Device.
Background technology
The scheme of existing solution liquid automatic control has following two big classes: one is floating-ball level switch type control
Mode class processed: traditional Liquid level is to be realized Liquid level by floating-ball type liquid-level switch, this mode is only
The point position being fixedly installed before dispatching from the factory can be used to carry out Liquid level, the height of water level can not be shown in real time,
And can not arbitrarily set change upper and lower limit and control height.
Another kind of by PLC, secondary instrument and floating-ball fluid level transmitter, magnetic flap level gauge, ultrasonic level gage etc.
The control system of other field instruments composition: as too big in the one-shot measurement component size using magnetic flap level gauge,
Cannot be used for narrow and small installation environment；With the control system of secondary instrument and other kinds of liquidometer composition due to
It is not unified in the error increase at double that the advance rower that dispatches from the factory makes to measure surely；Use PLC with other kinds
Liquidometer in the case of there will be cost and greatly increase.
Utility model content
The utility model proposes a kind of SCM Based liquid-level auto-control device,.
The technical solution of the utility model is achieved in that a kind of SCM Based liquid automatic control fills
Putting, including water pump and control parts, described control parts include a fluid level transmitter being arranged in water,
And a digital liquid level measurement and control instrument being connected with fluid level transmitter signal, the switch of water pump is surveyed with digital liquid level
Control instrument connects；The liquid level display screen that screen is double screen LED of described digital liquid level measurement and control instrument, described liquid level shows
Being additionally provided with an integral thickness shielded outside display screen is the glass screen of 2mm.
As preferably, described digital liquid level measurement and control instrument is a single-chip microcomputer, this single-chip microcomputer is connected to reset circuit,
Key circuit, water level signal Acquisition Circuit, display circuit, optical alarm circuit and water pump add water circuit.
As preferably, described water level signal Acquisition Circuit includes level sensor, the water level voltage being sequentially connected with
Change-over circuit, amplifying circuit, filter circuit and A/D converter, described display circuit includes being sequentially connected with
Display decoding circuit and display, described water pump adds D/A converter that water circuit includes being sequentially connected with, adds water
Display lamp, photoinduction switch and water pump.
Compared with prior art, the utility model has the advantage of: display liquid level that can be real-time, facilitate work
Make checking of personnel, and can arbitrarily set change upper and lower limit control height；In display part by LCD screen
Change to double screen LED and strengthen digital-scroll technique, also there is under severe working environment the highest brightness convenient existing
Staff's viewing of field；It is the glass screen of 2mm by additional for a display screen integral thickness, reaches instrument board
Duplicate protection, is hardly damaged under severe working environment.
Accompanying drawing explanation
Fig. 1 is fundamental diagram of the present utility model.
In figure: 1, fluid level transmitter；2, water pump；3, digital liquid level measurement and control instrument；4, glass screen.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, to the technical side in this utility model embodiment
Case is clearly and completely described, it is clear that described embodiment is only that this utility model part is implemented
Example rather than whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art
The every other embodiment obtained under not making creative work premise, broadly falls into this utility model and protects
The scope protected.
Embodiment: seeing Fig. 1, a kind of SCM Based liquid-level auto-control device, including water pump 2 and control
Parts processed, described control parts include a fluid level transmitter being arranged in water 1, and one becomes with liquid level
Sending the digital liquid level measurement and control instrument 3 that device 1 signal connects, the switch of water pump 2 is connected with digital liquid level measurement and control instrument 3；
The liquid level display screen that screen is double screen LED of described digital liquid level measurement and control instrument 3, outside described liquid level display screen also
It is provided with the glass screen 4 that integral thickness shielded is 2mm.
As preferably, described digital liquid level measurement and control instrument 3 is a single-chip microcomputer, and this single-chip microcomputer is connected to the electricity that resets
Road, key circuit, water level signal Acquisition Circuit, display circuit, optical alarm circuit and water pump 2 add water circuit.
As preferably, described water level signal Acquisition Circuit includes level sensor, the water level voltage being sequentially connected with
Change-over circuit, amplifying circuit, filter circuit and A/D converter, described display circuit includes being sequentially connected with
Display decoding circuit and display, described water pump 2 adds D/A converter that water circuit includes being sequentially connected with, adds
Water display lamp, photoinduction switch and water pump 2.
Fluid level transmitter 1 is put in measured water or in other kinds of liquid, fluid level transmitter 1
According to the change of water level, the electric current correspondence being converted into 4-20mA exports in liquid level controlling instrument, measure and control instrument
4-20mA electric current is converted to level value, it is achieved the real-time display of liquid level, and according to user's field requirement
The high high position of setting, a high position, low level, low low-side switch amount report to the police output to control the execution machines such as water pump 2, valve
Structure.And liquid level controlling instrument can match the output of 4-20mA electric current or RS485 communication function, facilitates networking
