Description
Technical field
The present invention relates to a kind of V-type filter tank perseverance method for controlling water level.
Background technique
Relatively advanced one of the technique filter tank of the current world's technique in V-shaped filter tank, and automatic constant water level control is the filter tank
Key link, by the adjustment to water regulating valve out by each filter tank water level control in a certain range.PID instruction is generallyd use to adjust
Section, less effective, water outlet valve regulation excessively frequently reduce the service life, the requirement for reaching permanent water level that can not be best, therefore
It replaces PID to instruct with a kind of new thinking, preferably realizes the permanent water level control in V-type filter tank.It is efficient to reach filter tank
Cross drainage.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide one kind to replace PID control mode from design pattern,
Preferably realize the permanent water level control in V-type filter tank.
The purpose of the present invention is achieved through the following technical solutions: a kind of V-type filter tank perseverance method for controlling water level, including
Following steps:
S1: the upper limit Wh and lower limit WL (the fluctuation model that namely filter tank liquid level W allows that filter tank need to be adjusted are determined first
It encloses)；
S2: the regulating time (namely acquiring the time interval of each filter tank liquid level of V-type) of acquisition filter tank liquid level is determined；
S3: judge current time acquisition level value whether S1 determine range in, if in the range filter tank without
It need to be adjusted, if not in the range, filter tank need to carry out necessary adjusting, specific method sees below step:
If the super upper limit Wh of the collected level value of S31, subtracts upper limit value Wh with collection value, if collected level value is low
In lower limit WL, then lower limit value WL is subtracted with collection value；
S32: current time collected level value Wn and the collected level value Wn-1 of previous moment are subtracted each other as filter
Liquid level changes △ W in a cycle time interval of pond；
S33: step S31 is multiplied with the value of step S32 as filter tank adjustment marks K；
S34: product K in step S33 if it is greater than zero, then with the value of step S31 divided by the value of step S32, and multiplied by
The minimal adjustment unit K0 of regulating valve, and with existing regulated value (i.e. existing valve opening) Kn plus (when collection value is greater than the upper limit
When value) or to subtract the result calculated (when collection value is less than lower limit value) be exactly the final regulated value calculated；
If the product in step S33 is equal to zero, increase on the basis of existing regulated value Kn (when collection value is greater than the upper limit
When value) or subtract a minimal adjustment unit (when collection value is less than lower limit value)；
If the product in step S33 less than zero, keeps existing regulated value Kn constant.
It is preferred that filter back washing and stopping the pond stage without permanent water level regulation.
It is preferred that the minimal adjustment unit of regulating valve is set as 2 degree.
The beneficial effects of the present invention are: V-type filter tank, as the most important technique filter tank of two factory of water, its stable water supply is right
It is not small that full factory completes monthly, annual water supply target contribution.The more stable permanent water level that ensure that V-shaped filter tank of the present invention supplies water.
Detailed description of the invention
Fig. 1 is control flow chart of the invention.
Specific embodiment
Technical solution of the present invention is described in further detail with reference to the accompanying drawing, but protection scope of the present invention is not limited to
It is as described below.
As shown in Figure 1,
The filter tank W- scale liquid level
Liquid level changes in a cycle time interval of the filter tank △ W-
The filter tank K- adjustment marks
The filter tank K0- regulating valve adjusts unit scales every time
The filter tank Kn- adjusts threshold values
The filter tank the Wh- Liquid level upper limit
The filter tank WL- Liquid level lower limit
Wn- current time liquid level
Wn-1- last moment liquid level
A kind of V-type filter tank perseverance method for controlling water level, includes the following steps:
S1: the upper limit Wh and lower limit WL (the fluctuation model that namely filter tank liquid level W allows that filter tank need to be adjusted are determined first
It encloses)；
S2: the regulating time (namely acquiring the time interval of each filter tank liquid level of V-type) of acquisition filter tank liquid level is determined；
S3: judge current time acquisition level value whether S1 determine range in, if in the range filter tank without
It need to be adjusted, if not in the range, filter tank need to carry out necessary adjusting, specific method sees below step:
If the super upper limit Wh of the collected level value of S31, subtracts upper limit value Wh with collection value, if collected level value is low
In lower limit WL, then lower limit value WL is subtracted with collection value；
S32: current time collected level value Wn and the collected level value Wn-1 of previous moment are subtracted each other as filter
Liquid level changes △ W in a cycle time interval of pond；
S33: step S31 is multiplied with the value of step S32 as filter tank adjustment marks K；
S34: product K in step S33 if it is greater than zero, then with the value of step S31 divided by the value of step S32, and multiplied by
The minimal adjustment unit K0 of regulating valve, and with existing regulated value (i.e. existing valve opening) Kn plus (when collection value is greater than the upper limit
When value) or to subtract the result calculated (when collection value is less than lower limit value) be exactly the final regulated value calculated；
If the product in step S33 is equal to zero, increase on the basis of existing regulated value Kn (when collection value is greater than the upper limit
When value) or subtract a minimal adjustment unit (when collection value is less than lower limit value)；
If the product in step S33 less than zero, keeps existing regulated value Kn constant.
In a preferred embodiment, filter back washing and stop the pond stage without permanent water level regulation.
In a preferred embodiment, the minimal adjustment unit of regulating valve is set as 2 degree.
The present invention uses from design pattern and replaces PID control, preferably realizes the permanent water level control in V-type filter tank.To
Reach filter tank high efficiency filter water.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, it is noted that all
Made any modifications, equivalent replacements, and improvements etc. within the spirit and principles in the present invention should be included in guarantor of the invention
Within the scope of shield.
