Embodiment two
Fig. 6 shows another embodiment of information about power acquisition device of the invention.Information about power in the embodiment
Acquisition device includes multiple sub-devices, is divided into multiple groups of A, B, C ... of series connection, includes in parallel connect in each group
The multiple sub-devices connect, such as A1, A2, A3.The quantity of each group neutron device can be different, and electrolyte is from converging to point each time
The numbers of branches of stream can be the same or different.There is the different intensity of light source and/or difference between the sub-device of difference group
Cuvette thickness, such as A1 is identical as the intensity of light source of B1, and cuvette thickness is set to different value or A1 and B1's
The intensity of light source is different, and cuvette is with a thickness of identical value；And it is thick with the sub-device intensity of light source having the same and cuvette organized
Degree, such as A1 and A2 have identical attribute, in this way, the multiple data obtained in same group can be compared to each other to reduce

Sample can further increase the data volume for analysis in limited device space, take into account plant bulk and monitoring is accurate
The requirement of property.
Below with reference to embodiment two, the present invention is further explained.
In all-vanadium liquid flow energy storage system, the flowing of electrolyte is by component " pump " Lai Shixian, and the flow of pump is in reality
In be programmable known quantity, we indicate overall flow rate when flowing through A group sub-device with L (A) (liter)/(minute), accordingly
Overall flow rate when flowing through each group of sub-device is all indicated by L (mark of sub-device group) (liter)/(minute).
The thickness of any group of sub-device cuvette is known quantity, therefore we can calculate according to quantity and thickness
For each sub-device come the flow shared, flow is devised a stratagem really at this time calculates, consideration total flow and thickness unrelated with light source.This
In consider two kinds of situations: if the thickness of one group of sub-device is consistent, the flow velocity of each sub-device electrolyte inside
=L (mark of sub-device) (liter)/(minute)/sub-device quantity；If the thickness of one group of sub-device is inconsistent, basis
Overall apparatus figure is it is found that flow is consistent, and total flow will carry out pro rate according to different-thickness, that is, flow through some in order to guarantee to pass in and out
Flow velocity=L (mark of sub-device) (liter)/(minute) × (thickness of some sub-device)/(all sub-device thickness of sub-device
Summation)；Therefore, according to it is proposed that device total figure, the flow velocity for flowing through each sub-device can be expressed as G (u, v), wherein
U indicates the mark (such as A, B ..., Z) of sub-device group；V indicates sub-device in the position of the sub-device group, as shown in fig. 6, right
In A group, the value range of v is the integer of [1, a].Likewise, we can indicate it with P (u, v) for each sub-device
Thickness.
On the basis for considering flow velocity G (u, v) and thickness P (u, v), we can basis for the setting of the intensity of light source
The voltage of offer and the electric current flowed through determine that, that is, for each sub-device, we have the intensity of light source to indicate F (u, v).In order to
Installation and design production convenience, for each luminous component, we are provided with the LED of same number and type, logical in this way
It can be changed for electric strength by crossing variation supply voltage, and then change the characteristic of its luminous power, so intensity of light source F (u,
V) it can approximately be expressed as function corresponding to supply voltage (the luminous starting of LED is related with its supply voltage characteristic).
Therefore, a three-dimensional data, i.e. F (u, v), P (u, v) and G (u, v) are constructed, a three-dimensional data can be constructed
Space, we indicate the space with D (F (u, v), P (u, v), G (u, v)).The meaning of the corresponding real system in the space can be with
It is expressed as at certain illumination condition F (u, v), the acquisition system that electrolyte is flowed through according to flow velocity G (u, v) with a thickness of P (u, v)
System.From stating it is found that its three-dimensional data space constructs " conditioned space " entirely analyzed for the space.
The color sensor of sub-device is considered at this time, it will collects each sub-device real-time three under " conditioned space "
Primary color data, i.e. R G B tri- values (RGB), indicated with RGB (u, v), this data be exactly entirely analyze " conclusion is empty
Between ".
In entire all-vanadium flow system operation, only the concentration of electrolyte in charge and discharge process constantly into
Row variation, so its variation will construct the mapping relations between " conditioned space " and " conclusion space ".Therefore, it can finally obtain
It indicates considering that vanadium ion is real-time to following functional relation: RGB (u, v)=J (D (F (u, v), P (u, v), G (u, v)), α), J
The mapping relations of conditioned space D (F (u, v), P (u, v), G (u, v)) and conclusion space RGB (u, v) in the case of concentration α.
According to the system structure and functional relation of design: RGB (u, v)=J (D (F (u, v), P (u, v), G (u, v)), α) can
With training data sample as follows: for the electrolyte of known concentration, building the sub-device of limited different-thickness, needle
Different changes in flow rate, different light source variations are simulated to each sub-device respectively, and then the electrolyte of known concentration is carried out
The foundation of data sample changes concentration of electrolyte and continues to repeat the process, to complete all-vanadium flow positive and negative anodes two sides difference vanadium
The foundation of the big data sample of ionic valence condition ratio, the big data sample are the normal data sample as detection information about power.
Fig. 7 shows the normal data sample acquiring method of one embodiment of the invention, we most start to select in general
What is taken is the maximum submodule of thickness；Known concentration electrolyte is sent into the circulator minimized, light source is set as minimum value,
Flow set is maximum value；Start to acquire data on basis herein, if the value difference of RGB is away from obvious at this time, is not close to count
According to the limiting value of division, such as it is integer 0 to 65536 that color, which is divided into integer in many sensors, if three values are all close
The limit, then just etc. long color be blocked, the numerical value of systematic sampling does not identify.Start to increase the intensity of light source at this time, such as
If fruit increasing is not obviously improved still, under the premise of reaching maximum light source, flow value is reduced, but if reaches setting
Minimum discharge also cannot be distinguished if, just data acquisition can only be carried out to the liquid stream of the concentration again with thinner submodule.
After the acquisition of all various concentration liquid streams terminates, the data sample of system is also constructed and is finished.
Fig. 8 shows the process of the information about power detection method of one embodiment of the invention, and this method is built upon conduct
On the basis that the big data sample of normal data sample has obtained, comprising:
It is whether normal (S81) to judge working condition for control system first, therefore controls in the initialization of startup stage
System can acquire the state of each submodule, be able to enter normal workflow to judge whether.If it find that acquisition
There is the case where working state abnormal in each submodule, then system will alarm and identify the abnormal module of specific works.
When the operating status for finding whole system is normal, then starts to carry out actual motion acquisition (S82), receive the information about power and adopt
The color data and intensity of light source data for the electrolyte that acquisition means are sent obtain cuvette thickness data.Next by acquisition
Data carry out data comparison (S83) with the big data sample database having had built up, according to becoming for electrolyte intermediate ion concentration variation
Gesture and curve obtain the vanadium ion concentration (S84) of positive and negative anodes, i.e., according to function RGB (u, v)=J (D (F (u, v), P (u, v), G
(u, v)), α), the value of ion concentration α can be found out, the ion concentration with remaining capacity be it is corresponding, according to ion concentration α's
It is worth remaining capacity and display (S85) it can be concluded that percents.When remaining capacity judges close to 0 or close to 100%, that
System will alarm, and close whole system to prevent from overcharging or over-discharge caused by system injury (S86).It otherwise, will be after
Continuous step S82, persistently monitors information about power in real time.
Through the foregoing embodiment, the detection method of quantity of electricity of the application utilizes normal data sample and collected color data
With intensity of light source date comprision, can in real time, be quickly obtained information about power；Further, using the thought of big data,
The color data under the different intensities of light source and cuvette thickness condition can be collected, to increase the data for analysis
Amount realizes more precisely electric power detection.
