=== Embodiment ===
<< About the environment >>
Before explaining the exhibition system of the present embodiment, the environment (air environment) of the space for accommodating the exhibits will be described.

The environment mainly includes temperature, humidity, and concentration of chemical substances in the air. Chemical substances are diffused into the space mainly from the interior materials of exhibition equipment. In addition, there is a risk that chemical substances may be diffused from the exhibition stand for decorating the exhibits, the work introduction plate, and the work itself. Hereinafter, each condition of temperature, humidity, and chemical substance will be described.

<Temperature>
・ Approximately 20 ° C (a temperature that is comfortable for humans) is good.
・ Avoid sudden changes in temperature as they will induce condensation.

<Humidity>
-Table 1 shows the relative humidity conditions according to the type (material) of the exhibit.

・複合的な展示物の場合は、５５〜６５％ＲＨにすることが一般的である。
・湿度の急激な変化は、結露や表面の剥離を誘発するので、避ける。
・湿度の対策としては、密閉度が高いエアタイト構造の展示設備と調湿剤を併用すればよい。但し、エアタイト構造の展示設備を用いると、化学物質濃度（後述）が高くなるおそれがある。

-In the case of a complex exhibit, it is generally set to 55-65% RH.
・ Avoid sudden changes in humidity as they will induce condensation and surface peeling.
-As a measure against humidity, it is advisable to use an exhibition facility with an airtight structure with a high degree of airtightness and a humidity control agent together. However, if an exhibition facility with an airtight structure is used, the chemical substance concentration (described later) may increase.

<Chemical substance>
-Table 2 shows the types, sources, effects, and control target values (standard values) of chemical substances.

表２に示すように、アンモニア、ギ酸・酢酸、アルデヒド類は、展示設備の内装材などから発生するため、展示物の材質に応じた管理目標値（基準値）内に管理する必要がある。特に、エアタイト構造の展示設備では、化学物質が内部に溜まっていき、経時的に内部の化学物質濃度が高くなるため対策が必要となる。

As shown in Table 2, ammonia, formic acid / acetic acid, and aldehydes are generated from the interior materials of exhibition equipment, so it is necessary to manage them within the control target values (standard values) according to the materials of the exhibits. In particular, in an exhibition facility with an airtight structure, chemical substances accumulate inside and the concentration of chemical substances inside increases over time, so countermeasures are required.

The temperature and humidity can be measured by installing a thermo-hygrometer inside the exhibition equipment, but if a sudden change in temperature and humidity occurs, the change could not be confirmed. .. In addition, as a method for measuring the concentration of a chemical substance, the following methods have been conventionally performed.

-Precision analysis method: Using a pump, the air inside is collected in ultrapure water or an adsorption tube for several tens of minutes to several hours, and analyzed using a dedicated analytical instrument. However, it is necessary to ask a specialized analysis institution, and it takes about 1 to 3 weeks for the results to be obtained.
-Detection tube method: A detector tube and a pump are installed inside the exhibition equipment, air is passed through the detector tube for several hours with a dedicated pump, and the concentration is checked by the discolored length.
-Passive indicator: An indicator with a diameter of about 1 cm is installed inside the exhibition equipment, and the concentration of chemical substances inside is checked from the degree of discoloration after a few days.

In all of these methods, it is necessary to open and close the door, and it takes time and effort, so that the chemical substance concentration has not been measured so much. Therefore, even if the concentration of chemical substances inside the exhibition equipment is high, it may not be noticed and may affect the exhibits.

Further, in the case of an exhibition facility capable of exchanging and accommodating different types of exhibits, it is difficult to manage the exhibits according to the exhibits because the environment suitable for each exhibit is different.

Therefore, in this embodiment, the environment (temperature, humidity, concentration of chemical substances in the air) in the exhibition facility can be easily monitored, so that the air environment suitable for the exhibit can be maintained. ..

<< About the configuration of exhibition system 1 >>
FIG. 1 is a schematic view showing the configuration of the exhibition system 1 of the present embodiment. Further, FIG. 2 is a schematic block diagram of the exhibition system 1.

The exhibition system 1 of the present embodiment includes an exhibition case 10 (corresponding to an exhibition facility) and a management device 20.

The exhibition case 10 includes a storage space 11, a sensor unit 12, a measurement unit 13, and an environment improvement device 114. The inner surface of the storage portion of the exhibit in the display case 10 of the present embodiment (the portion constituting the storage space 11) is covered with a plate material (veneer or the like) on a metal such as an iron plate, and the cloth is glued (or adhesive). The interior is finished by pasting. Therefore, chemical substances (ammonia, formic acid / acetic acid, aldehydes, etc.) as shown in Table 2 may be generated from the interior material.

The storage space 11 is provided inside the display case 10, and is a space in which different types of exhibits (for example, oil paintings, metals, ceramics, etc.) can be exchanged and stored. The display case 10 of the present embodiment has an airtight structure with a high degree of airtightness (air exchange rate is about 0.3 times or less per day), and the inside of the accommodation space 11 is highly airtight. Therefore, when a chemical substance is generated from an interior material or the like, the generated chemical substance is accumulated inside the accommodation space 11, so that the concentration of the chemical substance tends to increase over time. Therefore, in the present embodiment, as will be described later, the chemical substance concentration is detected and countermeasures can be taken.

The sensor unit 12 has a plurality of small sensor probes for measuring the environment in the accommodation space 11 of the exhibition case 10. Specifically, it has a temperature sensor probe 12A for measuring temperature, a humidity sensor probe 12B for measuring humidity, and a chemical substance sensor probe 12C (corresponding to a sensor) for measuring chemical substance concentration.

The chemical substance sensor probe 12C of the present embodiment can detect the concentrations of a plurality of chemical substances (at least ammonia, formic acid / acetic acid in Table 2). Specifically, the chemical substance sensor probe 12C is a chemical substance sensor that combines a sensitive film having different reactivity depending on the type (odor) of the chemical substance and a MEMS (Micro Electro Mechanical System) detection element. With this chemical substance sensor, it is possible to monitor a plurality of chemical substances by using a chemical substance measuring device that combines sensitive membranes having different characteristics and analysis by machine learning of artificial intelligence (AI). The chemical substance sensor is not limited to this, and for example, MSS (Membrane-type Surface stress Sensor) may be used, and a high-sensitivity gas that specifically corresponds to an individual substance may be used. If you have a monitor, you may use it. The sensitivity of the sensor may be at least 30 ppb of ammonia and 170 ppb of acetic acid, and even better if 10 ppb of formic acid can be measured.

Each of these sensor probes (temperature sensor probe 12A, humidity sensor probe 12B, chemical substance sensor probe 12C) is arranged at an inconspicuous position in the accommodation space 11 (in the present embodiment, the lower part of the accommodation space 11).

In the present embodiment, the temperature sensor probe 12A and the humidity sensor probe 12B are separate bodies, but a sensor (temperature / humidity sensor probe) capable of detecting both temperature and humidity may be used.

The measuring unit 13 is a part that measures the environmental data acquired by the sensor unit 12. In the present embodiment, the measuring unit 13 is provided in a portion below the accommodation space 11 of the exhibition case 10, but the present invention is not limited to this. For example, it may be provided on the side of the accommodation space 11. Further, the measurement unit 13 of the present embodiment includes a temperature measurement unit 13A, a humidity measurement unit 13B, and a chemical substance measurement unit 13C. The temperature measuring unit 13A measures the temperature data acquired by the temperature sensor probe 12A. The humidity measurement unit 13B measures the humidity data acquired by the humidity sensor probe 12B. The chemical substance measurement unit 13C measures the data of the concentration of a plurality of chemical substances acquired by the chemical substance sensor probe 12C for each chemical substance.

The environment improving device 14 is a device for improving the air environment in the accommodation space 11, and for example, as shown in FIG. 2, a ventilation device for ventilating, an air purifier device for purifying air, and a dehumidifying device are performed. It has a dehumidifying device and a humidifying device for humidifying. The operation (start / stop) of the environment improvement device 14 is controlled by the management device 20.

The management device 20 is a device for managing the display case 10, and is provided so as to be able to communicate with each part of the display case 10 (measurement unit 13, environment improvement device 14, etc.). The communication method is not particularly limited, and may be wired or wireless (wireless LAN, Bluetooth, etc.). Further, the management device 20 may be provided near the display case 10 or may be provided away from the display case 10. For example, the management device 20 may be provided in a separate room that is easy to monitor. Further, the management device 20 may be a personal computer, a smart device, or may be configured in the cloud. Further, the management device 20 and the display case 10 may be integrally provided.

The management device 20 of the present embodiment includes a data processing unit 21, a recording unit 22, a control unit 23, a device start / stop unit 24, and an alarm unit 25.

The data processing unit 21 receives each data measured by the measuring unit 13 and performs data processing, and compares the data with the management value (reference value) of the environment described later. Each data should be monitored regularly or continuously.

The recording unit 22 is a portion for recording each data measured by the measuring unit 13. By providing the recording unit 22, past data can be referred to, and sudden changes in the environment (temperature, humidity, chemical substances) can be detected. In addition, the recording unit 22 stores environment management values (reference values) predetermined for each type of exhibit.

The control unit 23 controls the environment in the accommodation space 11 to be within the control value based on the comparison result of the data processing unit 21. Specifically, each device of the environment improvement device 14 is operated (started) by the device start / stop unit 24, or the alarm unit 25 is made to give an alarm.

The device start / stop unit 24 is a portion that starts / stops the environment improvement device 14, and starts or stops the environment improvement device 14 according to an instruction from the control unit 23. As a result, when the air environment in the display case 10 deteriorates, the environment can be automatically improved.

The alarm unit 25 gives an alarm according to the instruction of the control unit 23. The type of alarm is not particularly limited, and may be, for example, display on a screen at the time of measurement, lighting (light emission) of a lamp of a specific color, alarm, contacting a terminal such as an administrator's smartphone. Further, the combination of the above-mentioned alarms may be used. As a result, the occurrence of abnormal values can be recognized in real time (abnormalities can be prevented from being overlooked), and air environment measures such as ventilation can be taken at the optimum timing.

<< About the management method of exhibits >>
First, the exhibit is stored in the storage space 11 of the display case 10 (corresponding to the storage process), and the type of the exhibit is set. The method of setting the type of the exhibit is not particularly limited. For example, a button (not shown) is provided in the display case 10 for each type of the exhibit so that the operator or the like presses the button corresponding to the exhibit. You may. Alternatively, the type of the exhibit may be set on the management device 20 side, or the type of the exhibit may be automatically detected by using artificial intelligence (AI) or the like. As a result, the control values (reference values) of the environment (temperature, humidity, chemical substances) corresponding to the exhibits are set. For example, when an oil painting is accommodated in the accommodation space 11, it is set to an environmental control value (see Tables 1 and 2) suitable for the oil painting. Further, when the metal is accommodated in the accommodation space 11, the control value of the environment suitable for the metal (see Tables 1 and 2) is set.

Next, each sensor probe of the sensor unit 12 measures the environment (temperature, humidity, chemical substance) of the accommodation space 11 (corresponding to the environment measurement process), and each measurement unit of the measurement unit 13 measures the acquired environment data. Measure each.

Then, the data processing unit 21 of the management device 20 processes the data of the measurement unit 13 and compares it with the management value (reference value) set for the exhibit (corresponding to the data processing process). When the measured value deviates from the control value, the control unit 23 controls to keep the environment within the control value (corresponding to the control process). That is, each device of the environment improvement device 14 is started by the device start / stop unit 24, and an alarm is issued by the alarm unit 25.

Further, in the present embodiment, since the data is recorded in the recording unit 22, a sudden change in temperature or humidity can be detected. Even when there is such a sudden change in temperature or humidity, the control unit 23 performs the above operation.

As a result, in the exhibition system 1 of the present embodiment, the inside of the accommodation space 11 of the exhibition case 10 can be maintained in an environment (temperature, humidity, chemical substance concentration) suitable for the exhibit.
