Description
Technical field
The present invention relates to computing system and calculation method field, especially a kind of water volume in water tank measuring and calculating with liquid level regulation
System and its calculation method.
Background technique
Skyscraper secondary water supply system is a kind of using relatively broad supply equipment, in work by city planting ductwork from
Water flows into storage in water tank, then extracts water out out of water tank by the booster pump that relevant device controls secondary water supply system and adds
Pressure is sent to user pipe and is used for skyscraper resident, guarantees the just common water of user, and in water supply process, water system is mating
Remote control float valve can real-time control water tank water level, guarantee that cistern water level is constantly in a high position.
In actual use, since water tank upper end is open state, water tank water level inside is constantly in highest in,
In this way, water in water tank will can be just finished by longer period of time, because containing chlorine in tap water when resident's water consumption is few
Gas, and the water in water tank is because use is slower, exposure cannot be replaced will cause water quality in air for a long time on tap water surface
It degenerates, influence is brought on the safe water of resident.Based on disadvantages mentioned above, currently advanced technology use liquid level sensor into
The control of row cistern water level sets water tank dynamic high, medium and low three water levels (such as setting water tank by liquid level sensor
Half is peak level), liquid level sensor is connected with water system main control board, when cistern water level is lower than water level in setting
When, the normally closed solenoid valve on the remote control float valve that connect with city planting ductwork of main control board control is opened, thus be water tank it is interior into
Row moisturizing, when water level is in setting high water level, remote control float valve closing is no longer intake, this ensure that water tank keeps certain water
Position, and the water energy in water tank is updated within a short period of time, causes water by dirt slowly so that water be prevented in water tank to use
Dye.
In secondary water supply system, need to count neighbours living using the water in water tank.Existing water consumption
Statistics is generally divided into contact and non-contact measurement, and most flow measurement is contact type measurement, as restriction flowmeter,
Pitot tube flowmeter, spinner flowmeter (such as common water meter), turbine flowmeter etc., such methods need in measurement pipeline
It is inserted into measurement device, structure is relative complex, and at high cost, precision is relatively poor, and what is be applicable in is the big measurement of fluid flow of flow velocity,
Therefore application has limitation.
Using the contactless flow of contactless measurement in respect of electromagnetic flowmeter and ultrasonic flowmeter etc., wherein
Electromagnetic flowmeter is using Faraday's electromagnetic induction law, and the flow that liquid is measured by Magnetic Sensor, flow velocity are to total
Amount is summarized, and the use of electromagnetic flowmeter has some limitations, for example fluid to be measured must be conductive liquid, and tie
Structure is more complicated, and cost is relatively high, therefore is not suitable for counting water tank water consumption.Ultrasonic flowmeter principle is to pass through
The speed that ultrasonic wave is propagated in a liquid is measured to detect the flow velocity of fluid, when flow velocity difference, ultrasonic wave is propagated in a liquid
Speed can change, available so different flow velocity and flow, and then total amount is summarized；Ultrasonic flowmeter
Any liquids and gases can be measured, but there is also certain limitations, for example temperature is excessively high to be unable to measure, when measurement needs
The place of being measured has the straight pipe of certain length just to can be carried out normal measurement, more demanding to measuring condition, if in pipeline
It also will affect its measurement accuracy there are large quantity of air, and its there is also structures more complicated, relatively high drawback of cost.
A storage of the urban water supply water tank (such as skyscraper secondary water supply system use water tank) as urban water supply
The related metering device such as water meter, flowmeter will not be usually arranged due to cost in water peak adjusting device before and after water tank, this

It is counted, if water meter can not be given and manage after cell inner water tank or when water run, drip, leak occur for water tank preceding pipeline
Personnel clearly prompt.If using in existing cell water system reinstall insertion in the complete pipeline including water tank
Formula water meter, the metrical instruments such as flowmeter, due to needing to change again pipeline, while mounting condition is limited, will lead to that difficulty of construction is big,
At high cost, effect is poor, while tune school is inconvenient after installation, needs to increase appendage, and it is also high to check cost.
Since above-mentioned water meter (including standard machinery rotator type water meter), ultrasonic flowmeter, electromagnetic flowmeter etc. rely on
Fluid flowing measures flow velocity, then in such a way that algorithm is cumulative dynamic measuring water consumption calculating basis is provided, by
To the influence of caliber, material temperature, environment, electronic component performance, algorithm and instrument installation site, variable factors are more, calculate essence
Degree will receive bigger influence.Simultaneously because the lower small flow of water flow velocity with the water period, uniformly exist initial-flow it is big or
The big problem of person's measurement error, phenomena such as being not allowed or can not measure there is also metering, therefore the measurement effect that cannot have reached.
In the water supply in city, entire city peak regulation water tank enormous amount, if each node do not have measuring instrument or
Measuring instrument metering inaccuracy, will lead to each node can not obtain accurately with water flow, and water undertaking also just can not be timely
The accumulative water data and real-time water data for effectively obtaining each node, can not obtain the domestic water of each node resident
Rule, cannot be instruct water factory more effectively produce and pipe network water delivery scheduling and cell secondary water supply system Energy Saving Control provide
Effective data are supported.

In water supply in order to overcome existing city, because each water tank node does not have measuring instrument or measuring instrument metering not
It accurately, cannot be that water factory is instructed more effectively to produce and pipe network water delivery scheduling and cell secondary water supply system Energy Saving Control, it can not
Accurately pipeline leakage provides the drawbacks of valid data are supported between analysis water outlet of water tank and user, and the present invention provides uses
Based on the data that the liquid level sensor installed in existing cell secondary water supply system water tank detects, combined data acquisition is single
Under member, information process unit, control unit collective effect, using completely new algorithm, integrated flow is combined using actuarial with estimation
Mode (usual actuarial time daily accounting is about 90%, and evaluation time accounting is about when 10%) can effectively obtain the non-moisturizing of water tank
