In the description of the present invention, the meaning of "plurality" is, unless otherwise stated.
The following first briefly introduces the design concept of the embodiment of the present invention:
in the embodiment of the present invention, a humidity adjustment device is mainly taken as an example of a humidifier for detailed description.
Taking an application scenario in which a plurality of humidifiers are installed in the same machine room as an example, as shown in fig. 1, the application scenario is a distribution diagram of a machine room humidifier in the related art, and it can be known from the diagram that each humidifier is independently distributed and independently works, and in this manner, due to the deviation of humidity values at different positions, imbalance of the operating rotation speed of each humidifier fan is easily caused, and the power consumption of the fan is large.
In view of this, the humidity control method and apparatus provided in the embodiments of the present invention, when a plurality of wet film humidifiers in a machine room operate, form a work group by communicating a plurality of humidifiers, and set a host to manage the plurality of humidifiers in the group, so that the plurality of humidifiers operate cooperatively, and can work alternately or jointly; the humidity in the machine room can be controlled, the rotating speed of the fan can be balanced and consistent, and the indoor humidity balance is guaranteed.
Fig. 2 is a schematic diagram of a group control connection of the humidifier according to an embodiment of the present invention. The humidifier comprises a working group, a master machine, a plurality of humidifiers, a plurality of fans, a plurality of communication lines and a plurality of communication lines, wherein the humidifiers which work independently form the working group through the communication lines, the master machine can be arranged in the working group and used for controlling the work of the humidifiers in the working group, the master machine can collect humidity information and fan rotating speed of the humidifiers and send the collected information to other humidifiers in the working group, and therefore data can be exchanged among the humidifiers.
The host can be any humidifier in the work group; or a third party control device such as a computer, a mobile phone, a tablet, etc.
In the embodiment of the present invention, when the host is any one of the humidifiers in the work group, optionally, an address may be set for each humidifier, one humidifier with the smallest address may be set as the host, or one humidifier with the largest address may be set as the host, and so on.
Taking the example shown in fig. 2 as an example, assuming that the addresses of the humidifier 1 to the humidifier N are gradually increased, when the humidifier with the minimum address is used as the host, the humidifier 1 may be selected as the host; when the humidifier with the largest address is taken as the host, the humidifier N can be selected as the host, and N is a positive integer.
The embodiment of the invention provides a brand-new group control scheme for humidifiers, which is mainly characterized in that each humidifier in a group is managed by an appointed host, so that the rotating speed of a fan is balanced, and the humidity in a machine room is balanced.
With respect to the above scenario, the following describes an embodiment of the present invention in further detail with reference to the drawings of the specification.
FIG. 3 is a flow chart illustrating a humidity control method according to an exemplary embodiment, as shown in FIG. 3, including the following steps.
In step S31, determining a humidity value of a humidity adjusting device in a humidity adjusting device group according to a plurality of humidity values acquired by a plurality of humidity sensors corresponding to the humidity adjusting device group, where the humidity adjusting device group includes a plurality of humidity adjusting devices, and one humidity adjusting device corresponds to at least one humidity sensor;
in step S32, determining a target humidity value corresponding to the humidity control device group according to the humidity value of the humidity control device;
in step S33, the target humidity value is sent to at least one humidity control device in the humidity control device group, so that the at least one humidity control device controls the ambient humidity according to the target humidity value.
By the scheme, the humidity adjusting equipment is regarded as a group, the target humidity value corresponding to the group is determined according to the humidity value of each humidity adjusting equipment, the humidity adjusting equipment in the group controls the environment humidity according to the target humidity value, group control over each humidity adjusting equipment in the group is realized, the humidity values received by the humidity adjusting equipment in the group are consistent and are all the target humidity values, and therefore the rotating speeds of fans of the humidity adjusting equipment are kept balanced, and the environment humidity is further kept balanced.
Referring to fig. 4, a schematic diagram of humidity acquisition according to an embodiment of the present invention is shown, where a humidity adjustment device group includes a plurality of humidity adjustment devices, and one humidity adjustment device corresponds to at least one humidity sensor. That is, as shown in fig. 4, a plurality of humidifiers are arranged in a computer room according to different server distribution positions, and each humidifier corresponds to a set of humidity sensors, that is, the humidity sensor on the right side of each server in fig. 4.
In fig. 4, the humidifiers are connected to each other through a Can (Controller Area Network) bus, and for any one humidifier, the humidity sensor corresponding to the humidifier is connected to the humidifier through an RS485 interface.
It should be noted that the positional relationship of the set of humidity sensors corresponding to each humidifier shown in fig. 4 is only an example, and may also be in a form that one server corresponds to a plurality of humidity sensors, or a plurality of servers correspond to one humidity sensor, and the like.
Optionally, when determining the humidity value of the humidity adjusting device in the humidity adjusting device group according to a plurality of humidity values collected by a plurality of humidity sensors corresponding to the humidity adjusting device group, there are a plurality of ways, which are listed as follows:
in the first aspect, for any one humidifier, an average value of the humidity values acquired by the humidity sensors corresponding to the humidifier is used as the humidity value of the humidifier.
In the embodiment of the present invention, the host acquires humidity values collected by all humidity sensors, and may represent the acquired humidity values of the humidity sensors by using a matrix H in the following form:
Figure BDA0002336283930000091
wherein m represents the number of the humidifiers, n represents the number of the humidity sensors corresponding to each humidifier, i is more than or equal to 1 and less than or equal to m, j is more than or equal to 1 and less than or equal to n, h ij And the humidity value acquired by the jth humidity sensor corresponding to the ith humidifier is represented.
For any humidifier i, the humidity value of the humidifier can be represented as an average value of the humidity values of the n humidity sensors corresponding to the humidifier, and the calculation formula is as follows:
H avg ＝(∑ j h ij )/n；
the Havg represents the humidity value corresponding to each humidifier, the humidity values are obtained by adding the same row elements in the H matrix and averaging, and the same row elements in the H matrix represent the humidity values collected by each humidity sensor corresponding to the same humidifier.
Suppose humidificationIf the humidifier 1 has 5 humidity sensors, i =1, n =5, the corresponding humidity value for the humidifier 1 is (H) 11 +H 12 +H 13 +H 14 +H 15 )/5。
Optionally, if n in the matrix H represents the number of humidifiers, and m represents the number of humidity sensors corresponding to each humidifier, that is, the same column element in the matrix H represents the humidity value collected by each humidity sensor corresponding to the same humidifier, havg = (∑ e) i h ij )/m。
Still taking the above embodiment as an example, there is m =5,j =1, and for the humidifier 1, the corresponding humidity value is (H) 11 +H 21 +H 31 +H 41 +H 51 )/5。
In a second mode, for any humidifier, a weighted average of the humidity values collected by the humidity sensors corresponding to the humidifier is used as the humidity value of the humidifier.
In this manner, the weight corresponding to each temperature sensor may be determined according to the distance between each humidity sensor and the humidifier corresponding to the group of humidity sensors, for example, the weight of the humidity sensor closer to the humidifier corresponding to the group of sensors is larger, and the weight of the humidity sensor farther from the humidifier corresponding to the group of sensors is smaller; or the weighting of the humidity sensor farther from the humidifier corresponding to the group of sensors is larger, and the weighting of the humidity sensor closer to the humidifier corresponding to the group of sensors is smaller, and the like.
Still taking the above-mentioned humidifier as an example, assume 5 humidity sensors corresponding to the humidifier 1, that the distances between the humidity sensors 1 to 5 and the humidifier 1 are from near to far, and that the weights corresponding to the humidity sensors 1 to 5 are a1, a2, a3, a4, and a5, respectively, where a1+ a2+ a3+ a4+ a5=1.
Taking the example that the same row element in the H matrix represents the humidity value acquired by each humidity sensor corresponding to the same humidifier, the humidity value corresponding to the humidifier 1 is:
(a1H 11 +a2H 12 +a3H 13 +a4H 14 +a5H 15 )/5。
in the third aspect, for any humidifier, the maximum humidity value among the humidity values acquired by the humidity sensors corresponding to the humidifier is used as the humidity value of the humidifier.
Still taking the above-mentioned humidifier as an example, if 5 humidity sensors corresponding to the humidifier 1 are assumed, if the same row element in the H matrix represents the humidity value acquired by each humidity sensor corresponding to the same humidifier, the humidity value acquired by each sensor is: h 11 >H 12 >H 13 >H 14 >H 15 Then the humidifier 1 corresponds to a humidity value of H 11 。
In the fourth aspect, for any one humidifier, the humidity value that is the smallest of the humidity values acquired by the humidity sensors corresponding to the humidifier is used as the humidity value of the humidifier.
Still by way of example in equation three, the humidity value corresponding to the humidifier 1 is H 15 。
And fifthly, regarding any humidifier, taking the median of the humidity values collected by the humidity sensor corresponding to the humidifier as the humidity value of the humidifier.
Also as exemplified in the third formula, the humidifier 1 has a humidity value H 13 。
It should be noted that, in the embodiment of the present invention, the manner of determining the humidity value of the humidifier in the humidifier group according to the plurality of humidity values collected by the plurality of humidity sensors corresponding to the humidifier group is only illustrated by way of example, and any manner of determining the humidity value of the humidifier in the humidifier group according to the plurality of humidity values collected by the plurality of humidity sensors corresponding to the humidifier group is applicable to the embodiment of the present invention.
In an optional embodiment, the target humidity value corresponding to the humidifier group is determined according to the humidity value of each humidifier in the humidifier group and the weight corresponding to each humidifier.
Specifically, the sum of the products of the humidity values of the humidifiers and the weights corresponding to the respective humidifiers is used as the target humidity value corresponding to the humidifier group.
For example, after the host machine determines the humidity values of the humidifiers according to the collected humidity values of the plurality of humidity sensors, the host machine calculates the humidity of the current working condition, namely the target humidity value corresponding to the humidifier group, in a weighting mode.
Setting: q is a weight matrix of 1 x m, and the value of each row of elements in Q represents the weight corresponding to each humidifier; havg is a humidity value matrix of m × 1, and the values of each row element in Havg represent the humidity value corresponding to each humidifier.
Then: target humidity value h avg ＝QHavg。
In an alternative embodiment, the weights of the humidifiers may be determined in a variety of ways, including:
determining the weight corresponding to each humidifier according to the value of each element in the weight matrix, wherein the weight matrix is obtained by dividing a standard humidity matrix by an actual humidity matrix, the elements in the standard humidity matrix are a plurality of preset standard humidity values, and the elements in the same row in the actual humidity matrix represent the actual humidity values corresponding to each humidifier under the same standard humidity value or the actual humidity values corresponding to the same humidifier under different standard humidity values.
For example, a plurality of standard humidity values are manually preset, wherein the standard humidity values represent humidity values in a standard environment, such as 10%, 20%, 30%, 40%, and the like.
In the embodiment of the present invention, the plurality of standard humidity values may be the same or different, and assuming that there are m standard humidity values, which are Hs1, hs2, \8230;, and Hsm, respectively, under each standard humidity value, the actual humidity values of m humidifiers in the humidifier group may be collected through a calibration method, wherein the determination method of the actual humidity value of each humidifier is the same as the method for determining the humidity value of each humidifier according to the humidity value collected by the humidity sensor corresponding to each humidifier, which is listed in the above embodiment, and thus, the description thereof is omitted.
The m groups of Hact humidity data, namely m groups of actual humidity data can be obtained by corresponding m times of calibration to the m standard humidity values, each group of actual humidity data comprises the actual humidity values of the m humidifiers under the current calibration, namely a group of actual humidity data comprises the m actual humidity values, so that the actual humidity matrix is an m multiplied by m matrix, wherein the same row of elements can represent the actual humidity values corresponding to all humidifiers under the same standard humidity value, or the actual humidity values corresponding to the same humidifier under different standard humidity values. The standard humidity matrix is related to the standard humidity matrix, and when the standard humidity matrix is a1 x m matrix, the same row of elements in the actual humidity matrix represent the actual humidity values corresponding to all the humidifiers under the same standard humidity value; if the standard humidity matrix is an mx 1 matrix, the same row element in the actual humidity matrix represents the actual humidity value corresponding to the same humidifier under different standard humidity values.
Let Hs denote the standard humidity matrix and Hact denote the actual humidity matrix, and when Q is 1 × m, hs is 1 × m, and Hact is m × m, QHact = Hs, and let Q matrix row and be 1, Q is obtained by right-dividing Hact by Hs.
When Q is mx 1, hs is mx 1, hact is mxm, hactQ = Hs, and Q is left-divided Hact by Hs assuming a Q matrix column sum of 1.
In an alternative embodiment, if the standard humidity matrix is divided by the actual humidity matrix, there are a plurality of weight matrices; when determining the weight corresponding to each humidifier according to the value of each element in the weight matrix, the value of each element in the target weight matrix may be used as the weight corresponding to the corresponding humidifier, where the target weight matrix is a weight matrix in the plurality of weight matrices, multiplied by the actual humidity matrix, and having the smallest variance with the standard humidity matrix.
Wherein, suppose that 10 humidifiers are in a certain humidifier group, the weight matrix Q comprises 10 elements Q1, Q2, 8230, Q10 corresponding to the humidifiers 1 to 10, wherein Q1+ Q2+ \8230 + Q10=1; hact is a 10 × 10 matrix; hs is a matrix of 1 × 10.
Under the constraint condition of Q1+ Q2+ \8230 ++ Q10=1, the optimal solution of the equation QHact = Hs, namely Q obtained when the variance D of Q × Hact and Hs is minimum, is the target weight matrix, and the target weight matrix is the optimal solution of the minimum value of the variance of Q pairs (Hs-Hact).
Suppose Q Hact = H, H is a matrix of 1 × 10, each element in the H matrix is H1, H2, H3, \\ 8230, each element in H10, hs is Hs 1 、Hs 2 、Hs 3 、…、Hs 10 Then:
D＝(H1-Hs 1 )^2+(H2-Hs 2 )^2+(H3-Hs 3 )^2+…+(H10-Hs 10 )^2。
if the values of the elements in the target weight matrix are 0.11,0.1,0.09,0.1,0.15,0.05,0.07,0.13,0.09, and 0.11, respectively, and correspond to the humidifiers 1 to 10, the values of the elements in the target weight matrix can be directly used as the weights corresponding to the humidifiers, for example, the weight corresponding to the humidifier 1 is 0.11, the weight corresponding to the humidifier 2 is 0.1, \8230, and the weight corresponding to the humidifier 10 is 0.11;
alternatively, when determining the weight of the corresponding humidifier according to the value of each element in the target matrix, the weights may also be proportional, for example, the weight corresponding to the humidifier 1 is 0.22, the weight corresponding to the humidifier 2 is 0.2, \ 8230, the weight corresponding to the humidifier 10 is 0.22, and the like.
And determining a second mode, and taking the ratio of the first preset value to the number of the humidifiers in the humidifier group as the weight corresponding to each humidifier.
Assuming that the first preset value is 1 and the number of the humidifiers is N, the weight corresponding to each humidifier is 1/N.
And determining a third mode, setting the weight corresponding to the target humidifier in the humidifier group as a second preset value, and setting the weights corresponding to other humidifiers as a third preset value, wherein the target humidifier is part or all of the currently working humidifiers, and the second preset value is larger than the third preset value.
Assuming that there are 10 humidifiers in the group of one humidifier, the humidifier working in the first cycle is 1 and 10 humidifiers; the humidifiers working in the second period are a humidifier 2 and a humidifier 9; the humidifiers operating in the third cycle are the humidifiers 3 and 8, \8230, the humidifiers currently operating in the first cycle are the humidifiers 1 and 10, so that the weights corresponding to the humidifiers 1 and 10 can be set to a second preset value, for example, 0.5, and the weights corresponding to the other humidifiers are set to a third preset value, for example, 0, and then the Q matrix can be represented as [0.5;0;0;0;0;0;0;0;0;0.5].
Optionally, the target humidifier may also be a humidifier with the largest humidity value and/or a humidifier with the smallest humidity value, etc.
Specifically, according to the measured humidity values of the humidifiers, the weight corresponding to the device with the largest humidity value and/or the humidifier with the smallest humidity value in each humidifier is set to be a fourth preset value, and the weights corresponding to the other humidifiers are set to be fifth preset values.
When measuring the humidity values of the humidifiers, a set of humidity data measured by a calibration method in the manner described in the determination method can be adopted, wherein the humidity data comprises the humidity values measured by m humidifiers under a certain standard humidity value.
For example, if the fourth preset value is 1, the fifth preset value is 0, and 10 humidifiers are used in total, where the humidifier 3 is the largest humidity value and the humidifier 5 is the smallest humidity value, Q = [0;0;1;0;0;0;0;0;0;0]; alternatively, Q = [0;0;0;0;1;0;0;0;0;0], etc.
In an optional embodiment, when the target humidity value is sent to at least one humidity adjusting device in the humidity adjusting device group, the target humidity value is sent to a part or all of the humidity adjusting devices in the humidity adjusting device group that are working in the present period.
The humidity adjusting device working in the period is determined according to the control rule, and if the control rule is a master-slave rule, the humidifier working in the period is taken as a master humidifier, and when the master humidifier is failed or the master humidifier is only adopted and cannot reach the expected humidity according to the preset requirement (for example, within the preset time), part or all of the backup humidifier can be started.
Assuming that the control rule is a polling rule, the polling period is one week, and 2 polling devices are provided, it indicates that two humidifiers work in each period, for example, 10 humidifiers are in a group of the total humidifiers, and the humidifier working in the first period is 1 and 10 humidifiers; the humidifiers working in the second period are a humidifier 2 and a humidifier 9; the humidifiers working in the third cycle are the humidifier 3 and the humidifier 8, the humidifiers working in the fourth cycle are the humidifier 4 and the humidifier 7, the humidifiers working in the fifth cycle are the humidifier 5 and the humidifier 6, the five cycles are a cycle, and after the fifth cycle is finished, the humidifier is continuously returned to be the first cycle of the work of the humidifier 1 and the humidifier 10.
When the humidifiers operating in the present cycle are the humidifier 4 and the humidifier 7, the target humidity value may be sent to some or all of the humidifiers 4 and 7.
It should be noted that, the humidifier required to operate in each period under the polling rule may be determined according to the position of each humidifier in the machine room, so as to ensure that the humidity of the machine room is balanced.
The polling rule and the main-standby rule listed in the embodiment of the invention are both control schemes capable of improving the room humidity measurement precision to a certain extent, and are beneficial to maintaining the stability and uniformity of a humidity field in a machine room. The polling rule can increase the service life and the operation stability of IT (Internet Technology) equipment, is favorable for prolonging the overall service life and saves energy.
In consideration of the fact that in the related art, under the mode that each humidifier works independently, humidity in a machine room is distributed unevenly, so that humidity sensors are inconsistent, the humidifiers work independently, the humidifier has different sizes, cannot exert collective force, and the humidifier cannot work at the optimal working point due to excessive loss of the humidifier.
An alternative embodiment is: and in the mode, all the humidity adjusting devices can work at balanced rotating speed, so that a control scheme that all the humidifiers work consistently is realized, the rotating speeds of the fans are kept balanced, the humidity in the machine room is kept balanced, the humidifiers work at the optimal working point is ensured, and energy is saved.

s54: judging whether Q has a solution, if so, executing S55, otherwise, returning to S51;
s55: and calculating the weight corresponding to each humidifier according to the solution of Q.
FIG. 6 is a flowchart illustrating a complete method for humidity control, according to an exemplary embodiment, including the following steps:
s61: acquiring humidity values acquired by humidity sensors corresponding to the humidifiers through a bus;
s62: for each humidifier, determining the humidity value of the humidifier according to the humidity value of the humidity sensor corresponding to the humidifier;
s63: calculating a target humidity value corresponding to the group of humidifiers according to the humidity value of each humidifier;
s64: sending the target humidity value to each humidifier;
s65: calculating a humidification requirement through a novel PID control algorithm;
s66: and controlling the humidifier by combining control rules of round inspection, main standby and the like.
In the embodiment of the invention, after the target humidity value is determined, the host can calculate the humidification requirement based on a PID control algorithm, and when the humidification requirement is calculated, the humidification requirement is mainly calculated according to the obtained target humidity value and the final humidity value required by the adjusted environment.
For example, the target humidity value is 60%, and the humidity value of the room environment is adjusted to 70%, that is, the final humidity value is 70%, the humidifier is controlled to continuously adjust the ambient humidity to reach the desired final humidity value, that is, the ambient humidity is adjusted from 60% to 70%, based on the calculation of the PID control algorithm.
In general, a PID control algorithm is mostly used for accurately controlling temperature and humidity in a temperature and humidity controller, and the PID controller is an automatic controller for controlling according to a deviation proportion (P), an integral (I) and a derivative (D). The proportion, integral and differential coefficients of the PID all have default set parameters, generally, the temperature and the humidity can be well controlled by using the default parameters, but relatively ideal parameter values can be found sometimes through debugging in specific special engineering, and the adjustment method can be carried out according to the action principle of the parameters in the whole PID process.
In the embodiment of the present invention, some optional adjusting methods include:
when humidification reaches the target humidity value very quickly, but the humidity overshoot is large: the proportion coefficient is too large, so that the proportion is too high before the set humidity is reached, and the P value can be adjusted to be small; alternatively, the differential coefficient is shown to be too large, rendering the response insensitive to the subject and allowing for large values of D.
When humidification often fails to reach the target humidity value, the time less than the target value is more: the proportion coefficient is too small, the humidification proportion is not enough, and the P value is increased; or, the integral coefficient is too small, the constant deviation is not sufficiently compensated, and the value I is increased.
When the target humidity value can be basically controlled, but the upper deviation and the lower deviation are large and frequently fluctuate: the differential coefficient is too small, the response to the instant change is not fast enough, the reflecting measure is not strong, and the D value is increased; or the integral coefficient is too large, so that the differential reaction is submerged and passivated, and the value of I is reduced.
When the influence of the working environment is large and fluctuation is caused when the change is slight, the surface differential coefficient is too small, the reaction to the instant change is not fast enough, the reaction cannot be carried out in time, the D value is increased, and the like.
In the embodiment of the invention, the PID control algorithm has the advantages of simple principle, easy realization, wide application range, mutual independence of control parameters, simpler selection of parameters and the like.
In addition, it should be noted that the humidity control method recited in the embodiment of the present invention is also applicable to temperature control, for example, temperature control in a machine room, and common temperature adjusting devices include an air conditioner, a fan, a heating pipe, and the like.
The temperature control device group control method is also the same reason when being applicable to a temperature control scene, carries out group control aiming at the temperature control device in the temperature control device group, according to the non-professor that the temperature sensor that the temperature control device corresponds gathered, confirms the target temperature value that the temperature control device group corresponds, can issue at least one temperature control device in the temperature control device group afterwards to the temperature balance etc. under the environment such as assurance computer lab.
