First, as shown in FIG. 1, the present invention provides a sensor node for continuously measuring and detecting an indoor environment state of a archive, and receiving and transmitting the indoor environment state data of the archives generated by each sensor node. The measuring device composed of a transmission / reception module is installed in each chamber or a predetermined position of the archives and performs a measurement-detection function of the part of the archives and the entire indoor environment. Specifically, each sensor node can affect the records.

This configuration makes it easy to measure and detect the part of the archives and the overall environmental conditions, and the sensor node can be installed even in a narrow space, making it difficult for people to access the indoor environment of the archives. It has the effect of enabling continuous management up to the state.

In addition, the management device consisting of a data logger, a data processing module, a pollution determination module, a control module, and a control module organizes the indoor environment state data of the measured and detected archives using the measuring device and comprehensively processes the indoor environment state. It is designed to determine whether the records are contaminated and to predict whether the records are damaged or damaged, and to take measures when the indoor environment of the archives is not desirable enough to damage the records.

That is, the data logger of the management device automatically records the indoor environment state data transmitted from each transmitting / receiving module of the measuring device, and automatically records the indoor environment state data continuously and continuously records clear indoor environment state data. Function, and the data processing module uses the indoor environment information of the archives recorded in the data logger, which has harmful effects on the records, such as temperature / humidity, fine dust (PM10), sulfur dioxide (SO2), nitrogen oxides (NOx), and ozone. Contamination of pollutants such as (O3), formaldehyde (HCHO), carbon monoxide (CO), volatile organic compounds (VOC), lighting, etc. The configuration provided to the judgment module has the effect of effectively managing data on various kinds of pollutants measured and detected at various places. It is.

In addition, the pollutant determination module, which is a main component of the present invention, uses the indoor environmental state data of the comprehensively processed archives provided by the data processing module to analyze and determine the presence of pollutants that may adversely affect the archives. And provide the result data to the control module accordingly. In other words, the conventional technique of simply measuring and checking the indoor environment of the archives is to measure and manage the concentration of each pollutant by the manpower using the measuring equipment without any special configuration, or to maintain the preservation conditions of the records according to the kinds of archives. Although there was a problem of not only subdividing and maintaining only the rough preservation conditions of the records, the indoor environment management and pollutant control system of the archives of the present invention according to the type of the record is determined by the pollutant determination module. There is an effect that can be managed by subdividing the preservation conditions of each record, and there is an effect that can be divided and managed according to the types of pollutants that can affect the records.

That is, the pollutant determination module calculates the pollutant index by the following calculation method using the comprehensive processed indoor environmental state data provided by the data processing module according to the kind of pollutant and the record. To determine whether the records are contaminated, the indicators indicate the concentration of contaminants on the surface of the records due to contaminants in the archives (R, the same as the amount of contaminants attached to the surface of the records) and the total exposure of the contaminants (Dose). Calculate

The calculation of the concentration of pollutants on the surface of the record (R, the amount of pollutant on the surface of the record) is based on the relationship between indoor air pollutant concentration and related variables in a manner that indicates the inflow and outflow of air into a completely mixed space. The mass balance model can be explained using a mass balance model such as Equation 1, which describes the relationship of the mass balance model. Contaminants are incompressible, ignoring losses due to impingement and diffusion of contaminants when air enters and exits indoors, and contaminants are reduced and eliminated by surface reactions (contact with records) in the interior space. Can be realized by establishing a general assumption for the application of the equation that the interior of the archives is a one-compartment. .

[Equation 1]

(C _i = indoor pollutant concentration (ppm), C ₀ = outdoor pollutant concentration (ppm), I = air exchange rate (ACH: Air Exchanges per Hour), S = strength of indoor pollutant generation (ppm / hr = cm ³ / hr m ³ ), R = interior pollutant adhesion (cm ³ / hr), V = interior volume (m ³ ), t = time (hr), m = mixing coefficient of interior space (0≤m≤1 ))

The concentration (R) of the indoor pollutant is the reduction constant (K) of the pollutant and the mass of the pollutant present (VC), assuming that the pollutant is reduced and eliminated due to the surface reaction (contact with the recording) in the indoor space. ) Can be expressed as Equation (2).

&Quot; (2) "

R = K × V × C

(K = contaminant reduction factor, V = surface area of record, C = contaminant concentration in indoor air)

That is, in relation to Equation 1 and Equation 2, the concentration of the pollutant on the surface of the record due to the pollutant in the archives (R, the amount of pollutant attached to the record surface) is The sum of the generation intensity of the archives indoor pollutants (mIC _i ) and the generation intensity of the archives indoor pollutants (dC _i / dt) over time at the archives indoor and outdoor pollution intensity (mIC ₀ + S). After subtracting, it can be obtained by applying it proportionally to the volume (V) of the archive storage space. The concentration of pollutant on the surface of the record obtained by this calculation method is determined by the reduction factor (K) of the pollutant and the surface area (V) and It can be seen that it is proportional to the concentration of pollutants in the archives indoor air.

In addition, as the other factors of the pollutant indicator, the total dose of pollutant (Dose) is determined by the concentration of pollutant (R (t)) on the surface of the record over time, the amount of pollutant absorbed (Ut (t)) over time, and the exposure time ( Equation 3 related to t) can express the total exposure amount of pollutants over time, and simply summarizing Equation 3 can realize the total exposure amount of the pollutants as equation 4. have.

&Quot; (3) "

&Quot; (4) "

Dose = R × Ut × ED

That is, according to Equation 4, the total exposure amount of the pollutant is It can be calculated by calculating the concentration (R) of contaminants mixed in the indoor air in the archives over time, the amount of pollutant absorption (Ut) of the record during the time, and the exposure period (ED) from the pollutants. .

In addition, the damage index (DI) is calculated by using the contaminant index expressed as the concentration of contaminants on the surface of the record (R, the amount of contaminant attached to the surface of the record) and the total exposure amount of the pollutant (Dose). Calculate to determine whether the records are contaminated with contaminants.

[Equation 5]

D.I = Dose / LOAED or NOAED

(DI = Damage Index, Dose = total exposure of pollutant, LOAED = Lower Observed Adverse Effect Dose, when the damage started, NOAED = No Observed Adverse Effect Dose, just before the damage occurred.

That is, the damage index (DI) is compared with the total exposure (Dose) of the pollutant for the record calculated by Equation (4) with the LOAED and NOAED values of the pollutant according to the record type and the pollutant type previously input to the database. Is in the range of 0.7 to 1 to generate contaminated judgment result data indicating that there is a risk of damage to the record, and when 1 is exceeded, contaminant judgment result data to warn that there is a risk of damage to the record is possible.
