Description

[Technical Field]

[0001] The present disclosure relates to a management device and a management method. [Background technology]

[0002] Conventionally, there is known a method for managing the work environment in a workplace such as a factory (for example, Patent Document 1). In Patent Document 1, the work environment is managed appropriately by generating a map showing the spatial distribution of the measured values ​​in the workplace using measurements taken by a mobile terminal worn by a worker. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 7243530 Summary of the Invention [Problem to be solved by the invention]

[0004] To protect the safety and health of workers, workplaces that handle designated hazardous substances are required to have their work environment measured periodically by a work environment measurement specialist, and a control classification is notified based on the measurement results. Workplace managers are required to make appropriate improvements to the work environment in accordance with the notified control classification. Although work environment measurements are conducted periodically by a work environment measurement specialist, they are not necessarily conducted frequently. For this reason, it is difficult for managers to meet their requests when they want to know the control classification.

[0005] Furthermore, even if one attempts to carry out work environment measurements simply without relying on a work environment measurement specialist, specialized knowledge is required to position the measuring device, and work environment measurements are time-consuming and costly.

[0006] Furthermore, although the management classification is notified in the form of a report, the cause of the adverse effects cannot be determined by looking at the results alone, and implementing countermeasures takes time and costs money.

[0007] For this reason, there is a need to easily understand the management classification of a workplace, but Patent Document 1 does not mention this point, and there is room for improvement.

[0008] One aspect of the present disclosure aims to easily understand the management classification of a workplace. [Means for solving the problem]

[0009] In order to solve the above problems, a management device according to one embodiment of the present disclosure is a management device that manages the work environment of a workplace, and includes: an acquisition unit that acquires measurement values ​​that indicate the work environment of the workplace, measured by at least one measurement terminal; a map generation unit that generates a map that represents the spatial distribution of the measurement values ​​in the workplace based on the measurement values; an area setting unit that sets a predetermined area on the map; a management classification estimation unit that estimates the management classification of the area as a management classification estimated value based on two different first and second indexes that are calculated from at least one of the measurement values ​​within the area and an interpolated value obtained by interpolating the measurement values ​​within the area; and a display control unit that displays the relationship between the first and second indexes and the management classification estimated value on a predetermined terminal.

[0010] In order to solve the above problems, a management method according to one embodiment of the present disclosure is a management method used in a management device that manages the work environment of a workplace, and includes an acquisition step of acquiring measurement values ​​that indicate the work environment of the workplace, measured by at least one measurement terminal; a generation step of generating a map that represents the spatial distribution of the measurement values ​​in the workplace based on the measurement values; a setting step of setting a specified area on the map; an estimation step of estimating the management classification of the area as a management classification estimated value based on two different first and second indexes calculated from at least one of the measurement values ​​within the area and an interpolated value obtained by interpolating the measurement values ​​within the area; and a display step of displaying the relationship between the first and second indexes and the management classification estimated value on a specified terminal.

[0011] The management device according to each aspect of the present disclosure may be realized by a computer. In this case, the management program that realizes the management device on a computer by causing the computer to operate as each part (software element) of the management device, and the computer-readable recording medium on which the management program is recorded, also fall within the scope of the present disclosure. [Effects of the Invention]

DETAILED DESCRIPTION OF THE INVENTION

[0014] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. The drawings used in the following description are schematic and do not necessarily reflect the actual product. For the convenience of illustration and ease of understanding, the scale and aspect ratios may be changed and exaggerated from the actual product. In the description of the drawings, the same parts are designated by the same reference numerals, and the description will not be repeated.

[0015] The terms "first," "second," "third," etc. used in this disclosure are used to distinguish a certain component from other components and are not intended to limit the number, order, priority, etc. of the components. For example, the presence of the terms "first element" and "second element" does not mean that only two elements, "first element" and "second element," are employed, nor does it mean that the "first element" must precede the "second element."

[0016] The terms "A measurement," "B measurement," "control concentration," "evaluation value," "first evaluation value," "second evaluation value," "first control category," "second control category," and "third control category" in this disclosure are defined in accordance with the "Work Environment Evaluation Standards" established by the Ministry of Health, Labor, and Welfare of Japan. Please refer to the following for these definitions, if necessary. https: / / www.mhlw.go.jp / web / t_doc?dataId=74088000&dataType=0&pageNo=1

[0017] (System Overview) Fig. 1 is a diagram illustrating an overview of a management system 100 according to an embodiment. As shown in Fig. 1, the management system 100 includes a workplace 10 to be managed, a management server 20 used to manage the work environment of the workplace 10, and a user terminal 50 operated by an administrator 40 who manages the work environment of the workplace 10.

[0018] The workplace 10 is, for example, a factory, a warehouse, etc. In such a workplace 10, a worker 11 operates machines, etc. to perform work such as production and processing. Although only one workplace 10 is shown in FIG. 1, the number of workplaces to be managed is not limited to one. The management server 20 may be configured to be able to manage multiple workplaces.

[0019] A plurality of measurement terminals 12 capable of measuring specific parameters within the workplace 10 are installed in the workplace 10. Examples of the specific parameters include six parameters: temperature, humidity, noise, illuminance, dust, and VOCs (volatile organic compounds). However, the types of parameters are not limited to these. The measurement terminals 12 may be configured to measure parameters other than these six parameters. In the example shown in FIG. 1, ten measurement terminals 12 are installed in the workplace 10, but the number of measurement terminals 12 installed in the workplace 10 is not limited to this.

[0020] The measurement terminal 12 continuously measures the temperature, humidity, noise, illuminance, dust, and VOCs inside the workplace 10. The measurement terminal 12 is provided with a communication interface. The communication interface is, for example, Wi-Fi (registered trademark). The measurement values ​​measured by the measurement terminal 12 are transmitted to the management server 20 via a predetermined relay device. The timing at which the measurement values ​​are transmitted to the management server 20 is not particularly limited. For example, the measurement terminal 12 may transmit the measurement values ​​to the management server 20 every 30 seconds.

[0021] The management server 20 is configured to be able to communicate with the measurement terminal 12 and the user terminal 50 via a communication network 30. The communication network 30 is, for example, the Internet. The location where the management server 20 is installed is not particularly limited, but for example, the management server 20 may be installed in a management center of a business that provides an information provision service regarding the work environment of the workplace 10. The management server 20 may be installed in Japan or outside of Japan. The management server 20 may also be a cloud server.

[0022] The management server 20 has a function of processing the measurement values ​​acquired from the measurement terminals 12, and provides various information relating to the work environment of the workplace 10 to the manager 40. The functions of the management server 20 will be described in detail later.

[0023] The administrator 40 can obtain various information about the work environment of the workplace 10 by accessing the management server 20 using a user terminal 50. The administrator 40 can also use the obtained information to appropriately manage the work environment of the workplace 10. As shown in FIG. 1, the user terminal 50 may be, for example, a laptop PC 51 or a smartphone 52. However, the user terminal 50 is not limited to these and may be a desktop PC, a tablet terminal, or a wearable terminal. If the management server 20 is configured as a cloud server, the administrator 40 can access the management server 20 from any terminal, regardless of time, date, or location, as long as the terminal is in an environment that can connect to the Internet.

[0024] In the workplace 10, working environment measurements are periodically conducted by working environment measurement experts to ensure the safety and health of workers 11. However, as mentioned above, although working environment measurements are periodically conducted by working environment measurement experts, the frequency of such measurements is not necessarily high. Therefore, when a manager 40 wants to know the management classification, it is difficult to satisfy that request. In this regard, the management system 100 according to this embodiment makes it possible to easily estimate the management classification by using measurements taken by the measurement terminal 12.

[0025] (Hardware configuration of management server 20) Next, an example of the hardware configuration of the management server 20 will be described with reference to Fig. 2. Fig. 2 is a block diagram showing an example of the hardware configuration of the management server 20.

[0026] 2, the management server 20 includes a processor 21, a main memory 22, an auxiliary memory 23, and a communication I / F 24. These components are connected via a bus 25 so as to be able to communicate with each other.

[0027] The main memory 22 is composed of a ROM (Read Only Memory), a RAM (Random Access Memory), etc. The auxiliary memory 23 is composed of a HDD (Hard Disk Drive), an SSD (Solid State Drive), etc., and stores measurement values ​​transmitted from the measurement terminal 12. The auxiliary memory 23 also stores a program for processing the measurement values. The program is loaded into the ROM. The processor 21 has a CPU (Central Processing Unit) that performs arithmetic processing, reads the program from the ROM, and executes the program using the RAM as a working area. Note that while FIG. 2 shows one processor 21, this is not limiting, and multiple processors 21 may be provided. Note that when the management server 20 is configured as a cloud server, such a cloud server may be provided with a virtual CPU.

[0028] The communication I / F 24 is implemented as hardware such as a network adapter, various communication software, or a combination thereof, and is configured to be able to realize wireless communication via the communication network 30.

[0029] (Function of processor 21 of management server 20) Next, an example of the functions of the processor 21 of the management server 20 will be described with reference to FIG. 3. FIG. 3 is a block diagram showing an example of the functions of the processor 21. By executing a program loaded into ROM, the processor 21 functions as an acquisition unit 211, a map generation unit 212, an area setting unit 213, an acquisition point setting unit 214, a calculation unit 215, a management division estimation unit 216, a graph generation unit 217, a management division map generation unit 218, and a display control unit 219. Note that the term "unit" here may be replaced with "circuit," "device," or "equipment," or alternatively, "step," "procedure," or "process." That is, the term "unit" may be realized by a program stored in the auxiliary memory 23 as described above, or may be implemented solely by hardware such as elements, devices, boards, and wiring, or by a combination of software and hardware. These functions will be described below.

[0030] The acquisition unit 211 acquires measurement values ​​(temperature, humidity, noise, illuminance, dust, and VOCs) indicating the work environment of the workplace 10 from the measurement terminal 12. More specifically, since the measurement values ​​are stored in the auxiliary memory 23, the acquisition unit 211 acquires the measurement values ​​by referring to the auxiliary memory 23. In other words, it can be said that the acquisition unit 211 acquires the measurement values ​​indirectly from the measurement terminal 12. The acquisition unit 211 outputs the acquired measurement values ​​to the map generation unit 212.

[0031] The map generation unit 212 generates a map showing the spatial distribution of measurement values ​​in the workplace 10 (here, as an example, the spatial distribution of harmful substances) based on the measurement values ​​acquired from the acquisition unit 211. Such a map is also called a heat map. Since the method of generating a heat map is well known, a detailed description thereof will be omitted. Note that, depending on the number and / or installation locations of the measurement terminals 12, there may be spaces without measurement values. For example, if the distance between the measurement terminals is large or if there are circumstances such as the measurement terminals 12 not being able to be installed due to some restriction, there may be spaces without measurement values. In such cases, the measurement values ​​between the measurement terminals may be interpolated. Examples of interpolation methods include linear interpolation, spline interpolation, polynomial interpolation, and bicubic interpolation. By interpolating the measurement values ​​between the measurement terminals in this way, a highly accurate map can be generated.

[0032] The area setting unit 213 sets an area on the map generated by the map generation unit 212. The "area" here refers to an area for which the administrator 40 wants to know the management classification. The method for setting the area is not particularly limited, and for example, the area setting unit 213 may set the area in accordance with input from the administrator 40. If the service provided by the management server 20 is SaaS (Software as a Service), the administrator 40 can send instructions to the management server 20 by operating dedicated software on the laptop PC 51. Such instructions can be considered as input from the administrator 40. The area setting unit 213 outputs the area set in accordance with the input from the administrator 40 to the acquisition point setting unit 214. Note that, in the following description, it is assumed that the area is set on a portion of the map generated by the map generation unit 212, but this is not limiting. The area may also be set for the entire map generated by the map generation unit 212.

[0033] The acquisition point setting unit 214 sets an acquisition point for acquiring a measurement value measured by the measurement terminal 12 in the area set by the area setting unit 213. The method for setting the acquisition point is not particularly limited, but for example, the acquisition point setting unit 214 may set the acquisition point in the area according to input from the administrator 40, similar to the area setting unit 213. The acquisition point setting unit 214 outputs the acquisition point set in the area to the calculation unit 215.

[0034] The calculation unit 215 acquires an interpolated value (hereinafter, sometimes simply referred to as an interpolated value) obtained by interpolating the measurement value of the acquisition point set by the acquisition point setting unit 214 and / or the measurement values ​​around the acquisition point. When the position of the acquisition point is within the measurement range of the measurement terminal 12, the calculation unit 215 may acquire the measurement value measured by the measurement terminal 12 at that position as the measurement value of the acquisition point. On the other hand, when the position of the acquisition point is outside the measurement range of the measurement terminal 12, the calculation unit 215 may acquire the interpolated value obtained by interpolating the measurement values ​​around the acquisition point using the interpolation process described above. Note that there may be cases where all of the positions of the acquisition points are within the measurement range of the measurement terminal 12, cases where all of the positions of the acquisition points are outside the measurement range of the measurement terminal 12, or cases where the positions of the acquisition points are both within and outside the measurement range of the measurement terminal 12.

[0035] The calculation unit 215 calculates the first evaluation value and the second evaluation value for the A measurement using the measurement values ​​and / or interpolated values ​​of all the acquired points. Hereinafter, the "first evaluation value and the second evaluation value for the A measurement" may be simply referred to as the A measurement value. The calculation unit 215 acquires the maximum value within the area and uses this maximum value as the measurement value for the B measurement. Note that the calculation unit 215 may also use the value of any point within the area as the measurement value for the B measurement. Hereinafter, the "measurement value for the B measurement" may be simply referred to as the B measurement value.

[0036] The calculation unit 215 normalizes the A measurement value and the B measurement value using a predetermined method. The normalized A measurement value will be referred to below as the "A measurement management class." Also, the normalized B measurement value will be referred to below as the "B measurement management class." The calculation unit 215 outputs the A measurement management class and the B measurement management class to the management class estimation unit 216.

[0037] The management division estimation unit 216 estimates the management division of the area as a management division estimated value using the A measurement management division and B measurement management division calculated by the calculation unit 215. Specifically, the management division estimation unit 216 calculates the management division estimated value of the area by averaging the A measurement management division and the B measurement management division. In this way, the A measurement management division and the B measurement management division according to this embodiment can be said to be indexes for estimating the management division of the area. The management division estimation unit 216 outputs the calculated management division estimated value to the graph generation unit 217 and the management division map generation unit 218.

[0038] The graph generating unit 217 generates a graph using the A measurement management category and the B measurement management category.

[0039] The management division map generation unit 218 generates a management division map using the management division estimated value calculated by the management division estimation unit 216. The management division map generated by the management division map generation unit 218 is a different map from the map representing the spatial distribution generated by the map generation unit 212.

[0040] The display control unit 219 displays predetermined information on the user terminal 50. For example, the display control unit 219 displays on the user terminal 50 the management division estimated value calculated by the management division estimation unit 216, the graph generated by the graph generation unit 217, the management division map generated by the management division map generation unit 218, etc.

[0041] (An example of a map showing the spatial distribution of measurements) FIG. 4 shows an example of a map representing the spatial distribution of measurement values ​​(here, as an example, the spatial distribution of hazardous substances) generated by the map generation unit 212. As shown in FIG. 4, the map represents the spatial distribution of measurement values ​​using color shading, color variations, etc., when viewed from above the workplace 10. Such a map allows the manager 40 to visually grasp the spatial distribution of hazardous substances and easily recognize areas with high and low concentrations of hazardous substances. Note that while the map in FIG. 4 is represented in two dimensions, it is not limited to this and may be represented in three dimensions.

[0042] (An example of GUI and / or CUI using dedicated software) FIG. 5 shows an example of a GUI (Graphical User Interface) and / or CUI (Character-based User Interface) of dedicated software displayed on a display 511 of a laptop PC 51. Such dedicated software is provided by the management server 20. The manager 40 can use the dedicated software provided by the management server 20 by accessing the management server 20 via the laptop PC 51. As shown in FIG. 5, the manager 40 can obtain information about the work environment of the workplace 10 and instruct the process of estimating the management classification of the workplace 10 by operating the GUI and / or CUI of the dedicated software displayed on the display 511 using a mouse, keyboard, etc.

[0043] As shown in FIG. 5, a map of the workplace 10 generated by the map generation unit 212 is displayed on the left side of the display 511. Assume now that the manager 40 wants to know the management classification for a specific area of ​​the workplace 10. In this case, the manager 40 can use a mouse to set an area indicated by a rectangular shape called A1 on the map. FIG. 5 shows an example in which the manager 40 sets the area A1 in a portion of the map, but as described above, the manager 40 may also set an area for the entire map. If the display 511 is configured as a touch panel, the manager 40 can set the area A1 using his fingertip.

[0044] When the administrator 40 sets an arbitrary area (here, A1) in the GUI of the dedicated software, a first signal indicating that the area has been set is transmitted from the laptop PC 51 to the management server 20. Upon receiving the first signal, the management server 20 assigns a uniquely distinguishable name to the area set by the administrator 40. In the example shown in FIG. 5, the management server 20 assigns the name "Area A1" to the area set by the administrator 40. As a result of this process, the name "Area A1" is displayed in the area name display region 60. By checking the display 511, the administrator 40 can know that the name "Area A1" has been assigned to the area he or she set. Note that the area name may be programmed so that the administrator 40 can input it himself or herself.

[0045] The management server 20 also detects the management concentration (mg / m 3 ) is displayed on the display 511. The "control concentration" here is an index used when determining the control classification from the work environment measurement results in order to judge whether the state of the work environment regarding hazardous substances is good or bad in the process of promoting work environment management. Such control concentration is set by the manager 40. The management server 20 displays the control concentration for area A1 set by the manager 40 in the area 61. By this process, the control concentration of "1.4" is displayed in the area 61 showing the control concentration. This allows the manager 40 to check the control concentration for area A1. Note that the control concentration for dust has been used as an example here. Regarding things other than dust, the expression "control value" is used instead of control concentration for temperature, humidity, noise, and illuminance. Therefore, temperature is shown as a control value (°C). Humidity is shown as a control value (%RH). Noise is shown as a control value (dB). Illuminance is shown as a control value (lx). For VOCs, the control concentration (mg / m 3 ) is shown.

[0046] After confirming the name of the area he or she has set (here, area A1) and the control concentration of area A1, manager 40 sets the number of measurement points in the X-axis and Y-axis directions of area A1. The X-axis direction is the horizontal direction in FIG. 5, and the Y-axis direction is the vertical direction in FIG. 5. This also applies to the subsequent drawings. Furthermore, the X-axis direction is also the horizontal direction when viewed from above of workplace 10, and the Y-axis direction is also the vertical direction when viewed from above of workplace 10.

[0047] In the example shown in Figure 5, the manager 40 sets the number of measurement points in the X-axis direction of area A1 to "6" as shown in area 62. The manager 40 also sets the number of measurement points in the Y-axis direction of area A1 to "4" as shown in area 63. According to the guidelines of the Ministry of Health, Labor and Welfare of Japan, measurement A is performed at the intersections of equal intervals of 6 m or less drawn vertically and horizontally around the workplace, with at least five measurements being taken per unit workplace. The manager 40 can set the number of measurement points in the X-axis direction and the Y-axis direction so that the acquisition points in area A1 meet the guideline criteria. However, they do not necessarily have to meet the guideline criteria. After setting the number of measurement points in the X-axis direction and the Y-axis direction, the manager 40 clicks the display button shown in area 64. If the manager 40 wants to change the number of measurement points in the X-axis direction and the Y-axis direction, he or she can click the delete button shown in area 65 and set the desired number of measurement points again.

[0048] When the administrator 40 clicks the display button shown in area 64, a second signal indicating that the display button has been clicked is transmitted from the laptop PC 51 to the management server 20. Upon receiving the second signal, the management server 20 sets acquisition points for area A1 according to the number of measurement points in the X-axis direction and the number of measurement points in the Y-axis direction. Details of the acquisition point setting will be described with reference to FIG. 6. FIG. 6 is a diagram illustrating the acquisition points set for area A1.

[0049] As shown in FIG. 6, the management server 20 sets the acquisition points so that they are equally spaced along the X-axis and Y-axis directions. As a result, six acquisition points are set at equal intervals along the X-axis direction in area A1, and four acquisition points are set at equal intervals along the Y-axis direction. That is, according to the number of measurement points set by the administrator 40, the acquisition points are set in a grid pattern in area A1 so that they are equally spaced along the X-axis and Y-axis directions. In the example shown in FIG. 6, 24 acquisition points PA are set. In this embodiment, these 24 acquisition points PA are defined as "measurement points of measurement A." The management server 20 acquires measured values ​​and / or interpolated values ​​measured by the measurement terminal 12 at all 24 acquisition points PA. The management server 20 calculates the first evaluation value and the second evaluation value for measurement A using the measured values ​​and / or interpolated values ​​of all acquisition points.

[0050] The calculation method for the first evaluation value and the second evaluation value will be described below. When measurements are taken on the same work day, the first evaluation value is expressed by Equation 1. Furthermore, the second evaluation value is expressed by Equation 2.

[0052]

number

[0053] Here, EA1 indicates the first evaluation value, M1 indicates the geometric mean value of the measurement values ​​of the A measurement, σ1 indicates the geometric standard deviation of the measurement values ​​of the A measurement, and EA2 indicates the second evaluation value.

[0054] It should be noted that the A measurement in this embodiment is not performed by placing actual measuring devices at 6 m intervals as specified in the guidelines. The A measurement in this embodiment means a virtual measurement, and therefore the first evaluation value and the second evaluation value are estimated values.

[0055] The management server 20 acquires the maximum value within area A1 and uses this maximum value as the B measurement value. The maximum value within area A1 may be the largest value among the measured values ​​and interpolated values ​​within area A1. The management server 20 may also use the value of an arbitrary point within area A1 selected by the administrator 40 as the B measurement value. As shown in FIG. 6, the administrator 40 may select the radio button shown in area 66 to instruct the management server 20 to set the measurement value of a desired coordinate in area A1 as the B measurement value. The administrator 40 may also select the radio button shown in area 67 to instruct the management server 20 to set the measurement value of a desired measurement terminal 12 as the B measurement value. In FIG. 6, the acquisition point from which the B measurement value is acquired is shown as acquisition point PB.

[0056] If a measurement value exists at acquisition point PB, management server 20 acquires the measurement value, and if a measurement value does not exist, acquires an interpolated value, and can use the acquired measurement value or interpolated value as the B measurement value.

[0057] In work environment measurements, measurements called "A measurement" and "B measurement" are carried out, and the "control classification" is determined by comparing the results with the control concentration. The control classification is an index for evaluating whether the work environment is being managed appropriately.

[0058] Following this example, in this embodiment, the management server 20 estimates the management category using the first and second evaluation values ​​related to measurement A and the measurement value B. Conventionally, the results of measurement A and measurement B were compared with a judgment table to evaluate the management category in one of three stages, from first to third.

[0059] Here, the conventional method for determining control classifications will be explained with reference to Table 1. However, because Table 1 is publicly available information, detailed explanations for all cases will be omitted and only representative cases will be explained. If the first evaluation value and the B measurement value are below the control concentration, the substance is classified into the first control classification. If the second evaluation value is below the control concentration and the B measurement value is above the control concentration and below 1.5 times the control concentration, the substance is classified into the second control classification. If the second evaluation value exceeds the control concentration or the B measurement value exceeds 1.5 times the control concentration, the substance is classified into the third control classification.

[0060] [Table 1]

[0061] The traditional three-level evaluation system makes it difficult to determine whether a work environment is on the safe side or the dangerous side within the same management category. For example, if a work environment is rated as Level 1, it is difficult for a manager 40 to determine whether it is close to Level 2 or far from Level 2. According to the definitions of the Ministry of Health, Labor and Welfare of Japan, Level 1 refers to a state in which work environment management is deemed appropriate, Level 2 refers to a state in which work environment management is deemed to have room for improvement compared to Level 1, and Level 3 refers to a state in which work environment management is deemed inappropriate. Therefore, if a work environment is rated as Level 1, but is close to Level 2, it may be desirable to improve the work environment. However, with the traditional three-level evaluation system, even if a work environment is close to Level 2, it is simply rated as Level 1, leading managers 40 to believe that work environment management is appropriate.

[0062] Therefore, in this embodiment, the A measurement value and the B measurement value are normalized between "0 and 3" based on the conventional judgment table (see Table 1 above). Normalization will be specifically described. When the conventional A measurement corresponds to "first evaluation value < control concentration," the A measurement value is normalized between "0 and 1" depending on the magnitude of the first evaluation value. When the conventional A measurement corresponds to "second evaluation value ≦ control concentration ≦ first evaluation value," the A measurement value is normalized between "1 and 2" depending on the magnitude of the first evaluation value and the second evaluation value. When the conventional B measurement corresponds to "second evaluation value > control concentration," the A measurement value is normalized between "2 and 3" depending on the magnitude of the second evaluation value. When the conventional B measurement corresponds to "B measurement value < control concentration," the B measurement value is normalized between "0 and 1" depending on the magnitude of the B measurement value. When the conventional B measurement corresponds to "control concentration ≦ B measurement value ≦ control concentration × 1.5," the B measurement value is normalized between "1 and 2" depending on the magnitude of the B measurement value. Furthermore, in the case of the conventional B measurement where "B measurement value > control concentration × 1.5" applies, the B measurement value is normalized between "2 and 3" depending on the magnitude of the B measurement value. As described above, the normalized value of the A measurement value is the "A measurement control category," and the normalized value of the B measurement value is the "B measurement control category." The normalized "A measurement control category" and "B measurement control category" are expressed as numbers between 0 and 3, and are also expressed as numbers consisting of an integer part and a decimal part. As described above, according to this embodiment, the evaluations of the A measurement and the B measurement, which were previously evaluated in three stages, are subdivided to estimate the control category, making it easier for the manager 40 to determine whether the same control category is on the safe side or the dangerous side.

[0063] (Management category estimation) The management server 20 uses the A-measurement management category and the B-measurement management category to estimate the management category of area A1 as a management category estimate. Specifically, the management server 20 calculates the management category estimate of area A1 by averaging the A-measurement management category and the B-measurement management category. FIG. 7 shows an example of how the calculated management category estimate is displayed. The management server 20 may display the management category estimate on the display 511 using, for example, a color bar. In the example shown in FIG. 7, the management category estimate is "1.6." Area A1 is colored in the color corresponding to "1.6" on the color bar. This display allows the administrator 40 to visually recognize the calculated management category estimate by numerical value and color.

[0064] (Graph showing measurement control category A and measurement control category B) FIG. 8 shows an example of a graph displayed on the display 511. The horizontal axis of FIG. 8 represents time, and the vertical axis represents the A measurement management category and the B measurement management category. Based on the time specified by the administrator 40, the management server 20 can display the time-dependent changes in the A measurement management category and the B measurement management category as a two-dimensional graph on the display 511. This allows the administrator 40 to visually grasp how the A measurement management category and the B measurement management category are changing over time. This makes it easier for the administrator 40 to grasp the change patterns, trends, and other change tendencies of the A measurement management category and the B measurement management category. This allows the administrator 40 to devise improvement measures for the work environment in accordance with the change patterns and trends, enabling appropriate management of the work environment.

[0065] 8, the display of the management classification estimated value is omitted, but the configuration may be such that when the administrator 40 places the cursor on any time axis, the management classification estimated value at that time is displayed. For example, when the administrator 40 places the cursor on the time axis indicating 17:35:00, the management classification estimated value that is the average of the A measurement management classification and the B measurement management classification at that time is displayed.

[0066] (Management classification map) 9-10 show examples of the A-measurement management division and the B-measurement management division displayed on the display 511. In FIGS. 9-10, the horizontal axis represents the A-measurement management division, and the vertical axis represents the B-measurement management division. The management division estimated value, which is the average of the A-measurement management division and the B-measurement management division, is plotted at the position indicated by the symbol 70. A diagram showing the relationship between the A-measurement management division and the B-measurement management division and the management division estimated value in two-dimensional coordinates is called a "management division map." In FIGS. 9-10, when the management division estimated value is plotted in the rectangular area indicated by "R1," the estimated management division corresponds to the conventional first management division. Furthermore, in FIGS. 9-10, when the management division is plotted in the L-shaped area indicated by "R2," the estimated management division corresponds to the conventional second management division. Furthermore, in FIGS. 9-10, when the management division is plotted in the L-shaped area indicated by "R3," the estimated management division corresponds to the conventional third management division. According to such a management classification map, the manager 40 can visually grasp which of the A-measurement management classification and the B-measurement management classification has the most dominant influence on the management classification. The estimated management classification value of the plot 70 shown in Figure 9 is "0.75."

[0067] As shown in FIG. 10, the management server 20 may plot the calculated management classification estimates so that their changes over time can be seen. FIG. 10 shows plots 70, 71, 72, 73, 74, and 75, progressing over time. In the example shown in FIG. 10, it can be seen that the management classification estimate in area A1 deteriorates from "0.75" to "1.15" over time. Furthermore, in the example shown in FIG. 10, the change in the A-measurement management classification is greater than the B-measurement management classification. This allows the manager 40 to infer that the A-measurement management classification is the cause of the deterioration in the work environment and to develop appropriate countermeasures. This allows the manager 40 to appropriately manage the work environment.

[0068] The management server 20 may simultaneously display the images shown in FIGS. 7, 8, and 9 on the display 511.

[0069] (Processing flow) Next, the flow of processing by the management system 100 according to this embodiment will be described with reference to Fig. 11. Fig. 11 is a sequence chart showing an example of processing by the management system 100 according to this embodiment.

[0070] In step S101, the measurement terminal 12 installed in the workplace 10 continuously measures specific parameters (e.g., temperature, humidity, noise, illuminance, dust, and VOCs) inside the workplace 10. The measurement terminal 12 transmits the measured values ​​to the management server 20 via a predetermined relay device. For example, the measurement terminal 12 may transmit the measured values ​​to the management server 20 every 30 seconds.

[0071] In step S102, the management server 20 acquires the measurement values ​​from the measurement terminal 12 via the communication network 30.

[0072] In step S103, the management server 20 generates a map representing the spatial distribution of the measurement values ​​in the workplace 10 (here, as an example, the spatial distribution of harmful substances) based on the measurement values ​​acquired in the process of step S102.

[0073] In step S104, the administrator 40 sets an area for which the administrator wants to know the management classification on the map generated in the processing of step S103. Here, it is assumed that area A1 has been set (see FIG. 5). The administrator 40 also sets the number of measurement points in the X-axis direction and the Y-axis direction of area A1 (see FIG. 5).

[0074] In step S105, the management server 20 sets the area A1 on the map generated in the processing of step S103 in accordance with the input from the administrator 40. The processing proceeds to step S106, and the management server 20 sets acquisition points for the area A1 according to the number of measurement points in the X-axis direction and the number of measurement points in the Y-axis direction in accordance with the input from the administrator 40 (see FIG. 6).

[0075] In step S107, the management server 20 acquires the measured values ​​and / or interpolated values ​​of all acquisition points set in the processing of step S106. The management server 20 calculates the first evaluation value and the second evaluation value for the A measurement using the measured values ​​and / or interpolated values ​​of all acquisition points. The management server 20 also acquires the maximum value within area A1 and uses this maximum value as the B measurement value. The management server 20 normalizes the A measurement value and the B measurement value between "0 and 3" based on a conventional judgment table to calculate the A measurement management category and the B measurement management category.

[0076] In step S108, the management server 20 estimates the management class of area A1 as a management class estimated value using the A measurement management class and the B measurement management class calculated in the processing of step S107. Specifically, the management server 20 calculates the management class estimated value of area A1 by averaging the A measurement management class and the B measurement management class.

[0077] In step S109, the management server 20 displays the management category estimated value calculated in the processing of step S108 on the user terminal 50. The user terminal 50 may display the management category estimated value using a color bar (see FIG. 7), may display the time-dependent changes in the A-measurement management category and the B-measurement management category in a two-dimensional graph (see FIG. 8), or may use a management category map to display the relationship between the A-measurement management category and the B-measurement management category and the management category estimated value in two-dimensional coordinates (see FIGS. 9 and 10).

[0078] The processing flow in the sequence chart shown in FIG. 11 is an example, and steps may be deleted, new steps may be added, or the processing order may be changed within the scope of the invention.

[0079] As described above, the management method of this embodiment includes an acquisition step (S102) of acquiring measurement values ​​indicating the work environment of the workplace 10 measured by at least one measurement terminal 12, a generation step (S103) of generating a map showing the spatial distribution of the measurement values ​​in the workplace 10 based on the measurement values, a setting step (S106) of setting a specified area on the map, an estimation step (step S108) of estimating the management classification of the area as a management classification estimated value based on two different first and second indexes calculated from at least one of the measurement values ​​within the area and an interpolated value obtained by interpolating the measurement values ​​within the area, and a display step (S109) of displaying the relationship between the first and second indexes and the management classification estimated value on a specified terminal.

[0080] (Action and effect) As described above, according to this embodiment, the following advantageous effects can be obtained.

[0081] The management server 20 is a management device that manages the work environment of the workplace 10. The management server 20 includes an acquisition unit 211 that acquires measurements indicating the work environment of the workplace 10 measured by at least one measurement terminal 12, a map generation unit 212 that generates a map showing the spatial distribution of the measurement values ​​in the workplace 10 based on the measurements acquired by the acquisition unit 211, and an area setting unit 213 that sets a predetermined area (e.g., area A1) on the map generated by the map generation unit 212 based on input from the manager 40. The management server 20 also includes a management classification estimation unit 216 that estimates the management classification of area A1 as a management classification estimate value based on two different first and second indices calculated from at least one of the measurement values ​​in area A1 and an interpolated value obtained by interpolating the measurement values ​​in area A1, and a display control unit 219 that displays the relationship between the first and second indices and the management classification estimate value on a predetermined terminal (e.g., user terminal 50). The "first index" here corresponds to the A measurement management classification. Also, the "second indicator" here corresponds to measurement management category B.

[0082] As described above, in workplaces 10 where hazardous substances are handled, work environment measurements are periodically conducted by work environment measurement experts. However, these measurements are not necessarily frequent. Therefore, it is difficult to satisfy the manager 40's request when he or she wants to know the control classification. In contrast, as in the above configuration, the control classification can be easily estimated by using the measured values ​​and / or interpolated values ​​measured by the measurement terminal 12. Furthermore, because the measurement terminal 12 can perform measurements continuously, the number of terminals installed in the workplace 10 can be reduced, and the control classification can be continuously estimated.

[0083] Furthermore, since the management classification can be continuously estimated, the manager 40 can continuously monitor the management classification to determine whether the deterioration of the working environment is occurring in the short term or the long term.

[0084] Furthermore, a plurality of measurement terminals 12 may be installed in the workplace 10. The management server 20 may further include a calculation unit 215 that calculates the first index and the second index. The area setting unit 213 may set a plurality of acquisition points PA arranged in a grid pattern on the area A1 based on input from the manager 40. The calculation unit 215 may acquire measured values ​​and / or interpolated values ​​at each of the plurality of acquisition points PA, and calculate the first index (measurement management category A) using the measured values ​​and / or interpolated values ​​at each of the plurality of acquisition points PA. The calculation unit 215 may calculate the second index (measurement management category B) using measured values ​​and / or interpolated values ​​in the area A1 acquired based on a predetermined condition. The "predetermined condition" here may be the maximum value in the area A1, or may be specified by the manager 40.

[0085] Even if one were to conduct a simple work environment measurement without relying on a work environment measurement specialist, specialized knowledge would be required to position the measurement instrument, and it would be time-consuming and costly to move the measurement instrument to each measurement point and measure at all of them. In contrast, as described above, by setting multiple acquisition points PA arranged in a grid pattern in area A1 and acquiring measured values ​​and / or interpolated values ​​from the multiple acquisition points PA, A measurement can be performed without actually installing a measurement instrument. Furthermore, the location where A measurement is performed can be freely changed. Therefore, with the above configuration, there is no need to position the measurement instrument, reducing the time and cost required for measurement.

[0086] Furthermore, even if the source of harmful substances changes, the appropriate measurement point B can be identified without specialized knowledge by using a configuration that automatically selects the maximum value.

[0087] Furthermore, the calculation section 215 may calculate the first index and the second index so that the first index and the second index have a decimal point.

[0088] With the conventional three-level evaluation, it was difficult to determine whether the same control category was on the safe side or the dangerous side. In contrast, with the above configuration, by subdividing the evaluations of the A and B measurements, which were conventionally evaluated on a three-level scale, and estimating the control category, the manager 40 can more easily determine whether the same control category is on the safe side or the dangerous side. For example, if the calculated control category estimate value is "0.9," it would be classified as the conventional first control category, but since it is closer to the conventional second control category, the manager 40 can determine that there is still room for improvement in work environment management, and can manage the work environment appropriately.

[0089] In addition, the display control unit 219 may display a two-dimensional coordinate with the first index (A measurement management category) and the second index (B measurement management category) as intersecting axes on a specified terminal (e.g., user terminal 50), and display the management category estimated value on the two-dimensional coordinate.

[0090] As described above, in the past, the management classification was reported in a report, but the cause of the adverse effects could not be determined by simply looking at the results, and implementing countermeasures was time-consuming and costly. In contrast, with the above configuration, for example, as illustrated in FIG. 10, since the change in the A measurement management classification is greater than that in the B measurement management classification, the manager 40 can infer that the cause of the deterioration in the work environment is the A measurement management classification and can develop countermeasures appropriate to the cause. This can reduce the time and cost required for countermeasures. Furthermore, a visually recognizable display configuration makes it easier for even a manager 40 lacking specialized knowledge to determine the management classification and notice environmental changes, etc.

[0091] Furthermore, the display control unit 219 may display the changes over time of the first index (measurement management category A) and the second index (measurement management category B) on a predetermined terminal (for example, the user terminal 50).

[0092] According to the above configuration, the manager 40 can easily grasp the change patterns, trends, and other change tendencies of the A measurement management category and the B measurement management category. This allows the manager 40 to plan improvement measures for the work environment according to the change patterns and trends, and to appropriately manage the work environment.

[0093] Other Embodiments In the above embodiment, an example has been described in which the manager 40 sets one area A1 on the map of the workplace 10, but the number of areas that can be set on the map of the workplace 10 is not limited to one. The manager 40 can set two or more areas on the map of the workplace 10. This point will be described with reference to Fig. 12. Fig. 12 shows another example of the GUI and / or CUI of dedicated software displayed on the display 511 of the laptop PC 51.

[0094] If the administrator 40 wants to know the management classifications of areas other than area A1, the administrator 40 can use the mouse to set areas A2 and A3 on the map, as shown in FIG. 12. When the administrator 40 sets an area, a first signal indicating that the area has been set is transmitted to the management server 20. Upon receiving the first signal, the management server 20 assigns uniquely distinguishable names to the areas set by the administrator 40. In the example shown in FIG. 12, the management server 20 assigns the names "Area A2" and "Area A3" to the areas set by the administrator 40. In addition to "Area A1," the area name field 60 also displays the names "Area A2" and "Area A3." By checking the display 511, the administrator 40 can see that the names "Area A2" and "Area A3" have been assigned to the areas he or she set.

[0095] Furthermore, management server 20 causes display 511 to display the control concentration for the area set by manager 40. As a result, a control concentration of "2.4" is displayed in area A2, and a control concentration of "2.8" is displayed in area A3.

[0096] After confirming the name and control concentration of the area that the manager 40 has set, the manager 40 sets the number of measurement points for area A2 and area A3. The management server 20 then sets acquisition points based on the set number of measurement points and estimates the control classifications of areas A2 and A3 as control classification estimates in the same manner as described above. In this way, by setting two or more areas on the map of the workplace 10, the manager 40 can simultaneously grasp the control classifications of two or more areas in the workplace 10. This enables the manager 40 to appropriately manage the work environment.

[0097] (correction processing) 9 and 10, it has been explained that the A measurement management category and the B measurement management category are displayed in two-dimensional coordinates. In this display mode, the management server 20 may correct the A measurement management category or the B measurement management category (the first index or the second index) according to the A measurement management category or the B measurement management category (the first index or the second index). This point will be explained with reference to FIGS. 13 to 16.

[0098] FIG. 13 shows areas where the A measurement management category or the B measurement management category is subject to correction. In FIG. 13, the two-dimensional coordinates are classified into seven areas (areas 80 to 86). Areas 80, 84, and 86 are areas that are not subject to correction. Area 83 is an area where the A measurement management category is corrected to "1.0". Area 81 is an area where the B measurement management category is corrected to "1.0". Area 85 is an area where the A measurement management category is corrected to "2.0". Area 82 is an area where the B measurement management category is corrected to "2.0". Area 80 corresponds to "area R1" in FIG. 9. The area obtained by adding together areas 81, 83, and 84 corresponds to "area R2" in FIG. 9. The area obtained by adding together areas 82, 85, and 86 corresponds to "area R3" in FIG. 9.

[0099] First, an example of a case where correction is not required will be described. As shown in plot 90 in FIG. 14, the A measurement control class is "1.5" and the B measurement control class is "1.4". Therefore, the calculated control class estimated value is "1.45". As shown in FIG. 14, when plot 90, i.e., the control class estimated value, is in area 84, the A measurement control class and the B measurement control class are not subject to correction. In the example shown in FIG. 14, a case where the control class estimated value is in area 84 has been described, but the same applies when the control class estimated value is in areas 80 and 86, and the A measurement control class and the B measurement control class are not subject to correction.

[0100] Next, referring to FIG. 15, a case where the A measurement management section is subject to correction will be described. In FIG. 15, as shown in plot 91, the A measurement management section is "0.3" and the B measurement management section is "1.3." Therefore, in this case, the average of the A measurement management section and the B measurement management section is "0.8." Plot 91 corresponds to the conventional second management section, but this "0.8" is a value below 1, which may cause discomfort to the administrator 40. Therefore, if the average of the A measurement management section and the B measurement management section is below the integer value of the higher of the A measurement management section and the B measurement management section, the management server 20 corrects the lower value to the integer value of the higher. Applying this specifically to the example of FIG. 15, the higher of the A measurement management section and the B measurement management section is "1.3," which is the B measurement management section. Therefore, the "integer value of the higher value" is "1." Because the average of the A-measurement management category and the B-measurement management category, "0.8," is below this "1," the management server 20 corrects the A-measurement management category from "0.3" to "1.0" (see plot 92). As a result of this correction, the estimated management category is calculated as "1.15," averaging the corrected A-measurement management category, "1.0," and the B-measurement management category, "1.3." With this correction, the calculated estimated management category exceeds 1, so the administrator 40 does not feel uncomfortable. Note that while FIG. 15 shows the estimated management category moving from plot 91 to plot 92, this is merely an illustration of the correction. After the correction, the numerical value indicating the estimated management category is displayed as "1.15," but please note that the position where the estimated management category is displayed on the management category map is plot 91, not plot 92. In other words, even after the correction, the position where the estimated management category is displayed on the management category map does not change.

[0101] Next, with reference to FIG. 16, a case where the B measurement management category is subject to correction will be described. In FIG. 16, as shown in plot 93, the A measurement management category is "2.2" and the B measurement management category is "0.2." Therefore, in this case, the average of the A measurement management category and the B measurement management category is "1.2." Plot 93 corresponds to the conventional third management category, but this "1.2" is a value below 2, which may cause discomfort to the administrator 40. Therefore, using the same method as described above, the management server 20 corrects the B measurement management category from "0.2" to "2.0" (see plot 94). With this correction, the estimated management category is calculated as "2.1" by averaging the "2.2" of the A measurement management category and the "2.0" of the corrected B measurement management category. With this correction, the calculated estimated management category exceeds 2, so the administrator 40 will not feel uncomfortable. The plot of the estimated management category in FIG. 16 is the same as that in FIG. 15. That is, in Figure 16, the estimated control class value is shown as having moved from plot 93 to plot 94, but this is merely an illustration of the above correction. When the above correction is made, the numerical value indicating the estimated control class value is displayed as "2.1," but please note that the position where the estimated control class value is displayed on the control class map is plot 93, not plot 94.

[0102] Although it has been described that multiple measurement terminals 12 are installed in the workplace 10, this is not limiting. For example, a configuration may be adopted in which only one measurement terminal 12 is used to measure the parameters of the workplace 10. It is also possible for the worker 11 to wear the measurement terminal 12 and move around the workplace 10 thoroughly, thereby measuring the parameters of the workplace 10 using only one measurement terminal 12.

[0103] [Software implementation example] The function of the management device can be realized by a program that causes a computer to function as the management device, and a program that causes a computer to function as each control block of the management device.

[0104] In this case, the management device includes a computer having at least one device (e.g., a processor) and at least one storage device (e.g., a memory) as hardware for executing the program. The computer executes the program to realize each function described in each embodiment.

[0105] The program may be stored non-transitory on one or more computer-readable storage media. The storage media may or may not be included in the management device. In the latter case, the program may be supplied to the management device via any wired or wireless transmission medium.

[0106] In addition, some or all of the functions of each control block can be realized by a logic circuit. For example, an integrated circuit in which a logic circuit that functions as each control block is formed is also included in the scope of the present disclosure. In addition, the functions of each control block can also be realized by, for example, a quantum computer.

[0107] Furthermore, each process described in each embodiment may be executed by AI (Artificial Intelligence). In this case, the AI ​​may run on the management device or on another device (for example, an edge computer or a cloud server).
