The function of judging the comfort of the working environment and adjusting the control leads to the technical problem that the comfort of the working environment cannot be effectively judged and adjusted.

The above is a detailed description of the second embodiment of a working environment monitoring and control device provided by the present application, and the following is an implementation process of the comfort level judgment module provided by the present application based on an expert system.

The input data of the expert system in this application are environmental parameters such as temperature, humidity, differential pressure, ventilation times, _PM2 . For each environmental parameter, it is divided into four different levels, namely excellent, good, fair and unsatisfactory.

The method used to determine the importance of environmental parameter weights is AHP, which uses an ordered hierarchical structure to represent a complex problem. At the same time, it can also rearrange the quality of decision-making solutions based on people's subsequent judgments about the problem. The key to AHP is that it combines qualitative and quantitative analysis, and uses quantitative evaluation instead of qualitative evaluation in the final result. The specific steps of this method are as follows:

1. First, establish a hierarchical structure. Analytic hierarchy process generally divides the problem into three layers, and the connection between each layer is represented by arrow lines. As shown in Figure 3, the three layers are the target layer, the criterion layer, and the scheme layer zi respectively.

2. Constructing the comparison matrix. The purpose of constructing the comparison matrix is to quantify the qualitative evaluation. To realize this process, the nine-level scaling method needs to be introduced into the AHP.

The content of the nine-level scaling method is to use one element as the comparison element 1 for comparison. When _zi and z _j (1) are equally important, then zi _ij takes the value of 1; when zi _i is more important than z _j , then zi _ij takes the value of 3; when z _i is more important than z _j , then z _ij Take the value 5; when zi is more important than z _j , then zi _ij takes the value 7; when zi _i is extremely important than _{z j, then zi ij} _takes _the value 9; for 2, 4, 6, and 8, it is the intermediate Intermediate cases of importance to which 1, 3, 5, 7, and 9 belong.

After comparison, a square matrix A=(a _ij )n×n can be obtained, which is called a pairwise comparison matrix, the ratio of _zi to z _j is a _ij , and the ratio of z _j to _zi is a _ji , And a _ij =1/a _ji , as shown in the following formula:

Taking the indoor environment of the office as an example, by collecting data, we can obtain the comparison relationship of each factor shown in Table 1, as well as the comparison matrix. The comparison matrix A is:

Table 1 Comparison of importance levels among environmental factors

After obtaining the comparison matrix A, find its corresponding eigenvector according to the maximum eigenvalue 7.2844 of the matrix. After (using matlab calculation) and normalizing each element of this feature vector, the weight vector Z can be obtained;

Z=(0.2934 0.0797 0.0354 0.2076 0.1059 0.1389 0.1389).

3. Consistency test of the judgment matrix. If the consistency requirement deviates too much from the standard, there may be a big deviation between the actual situation and the final comprehensive judgment conclusion. Therefore, it is necessary to judge and analyze the consistency index of the judgment matrix. The first step is to calculate the consistency index CI of the judgment matrix. λ _max is the largest eigenvector, and n is the order of the matrix. The calculation formula of the consistency index CI is as follows:

After obtaining the CI, it is also necessary to find out the average random consistency index RI corresponding to the judgment matrix in Table 2.

Table 2 Average random consistency index table

Then, the consistency ratio CR can be calculated, and the calculation formula of the consistency ratio CR is:

The criterion that the judgment matrix satisfies the consistency is that the calculated CR value is smaller than 0.1. When this condition is met, the judgment matrix is considered to meet the standard. Otherwise, the judgment comparison matrix A needs to be re-established. For the judgment matrix A, substituting into the calculation formula of the consistency index CI, the CI can be calculated to be 0.0474;

Select RI according to the order of the judgment matrix A, and then substitute CI into the calculation formula of the consistency ratio CR to obtain a CR of 0.0359. Since 0.0359 is less than 0.1, the weight matrix satisfies the consistency index.

Taking the environment of an ordinary office as an example, the standard of various environmental parameters that the human body is most comfortable in the office is first collected. Each criterion is then subdivided into four evaluation levels, which are excellent, good, fair and unsatisfactory. Taking temperature as an example, the most comfortable temperature in the human body is in the range of 20 to 26 °C, so the range can be subdivided into: excellent as [21, 25]; good as [20, 21)∪(25, 26]; generally as [18, 20)∪(26, 28]; the discomfort is (-∞, 18)∪(28, +∞), and the unit is °C.

Single-factor evaluation is performed on the seven basic environmental parameters. In single-factor evaluation, the membership function of each factor needs to be determined first. In this application, the assignment method is used to determine the membership function, and a rectangular distribution fuzzy function is selected. Linear distribution functions such as the rectangular distribution function are more conducive to programming, take less time to calculate, have better rapidity and stability, and are more conducive to real-time display of data.

Also taking the temperature parameter in the office environment as an example, the membership function can be obtained. The membership function is used to judge the evaluation of each parameter. The membership function is:

Among them, R(x) ₁ , R(x) ₂ , R(x) ₃ and R(x) ₄ represent excellent, good, fair and unsatisfactory in the evaluation set, respectively.

In the same way, the membership functions of other environmental parameters can be obtained, and it is assumed that the final evaluation results are shown in Table 3.

Table 3 Evaluation results of various environmental parameters

Then the fuzzy relation matrix R can be obtained:

Finally, only the fuzzy relation matrix R and the weight vector need to be used for fuzzy transformation to obtain the final result. The calculation formula of the result B is:

After calculation, B=(0.2934 0.0797 0.3132 0.3135), the result shows that the proportion of the environmental health at this time is "excellent" is 29.34%, the proportion of "good" is 7.97%, and the proportion of "average" is 31.32 %, while the proportion that considered "discomfort" was 31.35%. Therefore, the environmental quality at this time should be "uncomfortable".

In the calculation formula of result B, the operator in ZoR is the intersection operator of fuzzy sets. There are several different operators in fuzzy operations. For example. M(∧, ∨) operator, M(∧, e) operator, M(g, ∨) operator and M(g, e) operator.

M(∧, ∨), ∧ represents the process of taking small, and ∨ represents the process of taking large. This operator belongs to the main factor salient type operator. If there are many evaluation factors and the weight difference between the factors is not large, the ideal comprehensive results cannot be obtained.

M(∧, e) This operator uses ∧ as the multiplication operation in matrix operations and the bounded sum e operation as the addition operation in matrix operations. Bounded sum: a⊙b=min(a+b,1). But this will ignore some less important factors, making the results less objective.

M(g, ∨) This operator uses ordinary multiplication as the multiplication operation in the matrix operation, and uses the logical addition ∨ as the matrix addition operation. This operator is of weighted average type, but due to the use of logical addition, some secondary data will be lost, which will affect the quality of comprehensive evaluation to a certain extent.

M(g, e) This operator uses ordinary multiplication as the multiplication operation in matrix operations, and bounded sum e as the addition operation in matrix operations. The operator also belongs to the weighted average type, because it adopts a bounded sum, which can comprehensively consider all factors, and can obtain a satisfactory comprehensive evaluation result with a degree of membership not greater than 1.

In order to make the evaluation results more objective and credible, the M(g, e) operator is used in this operation, and a relatively ideal result is obtained.

Based on the judgment of comfort, comprehensive control of equipment is carried out. The adjustment control module 103 controls the corresponding equipment through wifi, adopts the fuzzy-PID control method for adjustment, and controls the adjustment of the temperature and humidity of the air conditioner, the start and stop of the humidifier, the exchange and stop of the fan, the operation of the air purifier, the negative oxygen ion generator, etc. Start and stop so that the temperature range is 21 ~ 25 ℃, the humidity range is 40% ~ 60%, the indoor and outdoor pressure difference is in the range of -5066 ~ 5066Pa, the ventilation frequency is 3 ~ 5 (times/h), the range of PM2.5 0～35μg/m ³ , CO2 concentration range is 350～450ppm, Tvoc concentration range is 0～270Ppb, negative oxygen ion range is more than or equal to 2000 (pieces/cm ³ ).

As mentioned above, the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand: The technical solutions described in the embodiments are modified, or some technical features thereof are equivalently replaced; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions in the embodiments of the present application.
