The indoor environment depends on, for example, the operating state of the air conditioning equipment, the open / closed state of the door of the entrance, the heat generated from the lighting fixtures and other electric appliances installed on each floor of the building, and the like. Therefore, in order to accurately grasp the operational issues of various equipment such as air conditioners related to the indoor environment, it is desirable to be able to accurately grasp the current indoor environment. Therefore, it is conceivable to visually grasp the current indoor environment by using contour diagrams that express environmental data such as indoor temperature distribution in different colors according to the values. For example, air conditioning equipment for the entire building. In order to understand the operational issues of, it is necessary to generate a contour diagram of the entire floor. In this case, based on the environmental data collected from the sensors installed discretely in each part of the floor, between the sensor installation locations. The contour diagram will be generated by interpolating the estimated value of the environmental data of. However, it is common for a partition to be installed on the floor to form a space for various purposes such as a living room or a library. Since the partition is usually constructed of a non-breathable plate material or the like, the airflow passing between the two spaces divided by the partition is blocked. Therefore, it is natural that the environmental data of each part of the floor expresses a peculiar difference of a critical value in the partition part, but the environmental data of the environmental data between the installation locations of the sensors discretely installed in each part of the floor. In the contour diagram generated by interpolating the estimated values, almost the same estimated values are calculated on both sides of the partition, so that such a peculiar difference as a critical value does not appear. That is, a contour diagram is generated in which the boundary of the partition is ambiguous and it is objectively clear that the distribution is different from the actual distribution of the environmental data. Therefore, if the indoor environment is grasped using such a contour diagram, there is a risk of misunderstanding the operational issues of various facilities.

Therefore, the present application is an indoor environment analysis device and method that enables appropriate generation of contour diagrams based on environmental data collected from sensors discretely arranged on the floor even on a floor on which partitions are installed. And disclose the program.

In order to solve the above problems, in the present invention, the area of the contour diagram on one side of the partition is color-coded based on the measured value of the environmental sensor on the one side, and the contour diagram on the other side is expressed. The area of is color-coded based on the measured value of the environmental sensor on the other side.

Specifically, the present invention is an indoor environment analyzer, in which the position input operation of each environment sensor installed in each part of the floor and the position input operation of each environment sensor installed on the floor are performed on the setting screen imagining the floor of the property. The floor environment is calculated by interpolating the estimated value of the environmental data between the installation locations of each environmental sensor from the input receiving means that can accept the input operation of the partition position and the measured value of the environmental data collected from each environmental sensor. The contour diagram is provided with a contour diagram generating means that generates a contour diagram in which data is color-coded according to a value based on an actually measured value, an estimated value, and the position information of each environmental sensor received by the input receiving means. When the partition whose position is input by the input receiving means is located between at least one pair of environmental sensors, the generation means is the environmental sensor on one side of the contour diagram area on one side of the partition. The measured value of is expressed by color-coding the area from the environmental sensor on one side to the partition, and the area of the contour diagram on the other side of the partition is based on the measured value of the environmental sensor on the other side. In addition, the area from the environmental sensor on the other side to the partition is color-coded.

Here, the property refers to all the structures forming the indoor space, for example, buildings, factories, plants, research facilities, underground malls, houses, station buildings, railroad cars, buses, aircraft, spacecraft, and all other structures. Is included. The environment sensor is a sensor that measures the indoor environment, and examples thereof include a temperature sensor, a humidity sensor, and various other sensors. Further, the environmental data is data expressing the indoor environment numerically, and examples thereof include temperature data, humidity data, and other data. Further, the partition is a member for partitioning a space, and examples thereof include a wall material and a plate material having no breathability, a perforated wall material and a plate material having a breathability, a curtain, a roll screen, and various other members. Be done.

With the above analysis device, for the area of the contour diagram on one side of the partition, the value of the environmental data of the partition portion is determined based on the measured value of the environmental sensor on the one side. Then, the estimated value of the environmental data from the environmental sensor on one side to the partition portion is interpolated and calculated based on the measured value of the environmental sensor and the determined value. Therefore, the contour diagram on one side is generated without being affected by the measured value of the environmental sensor on the other side of the partition. The same applies to the area of the contour diagram on the other side.

That is, in the contour diagram generation process performed by the analysis apparatus, the region on one side of the partition and the region on the other side are color-coded in a state of being separated from each other. Therefore, the contour diagram generated by the above-mentioned analysis device is a diagram in which the boundaries of the partitions are clear when the entire portion having the partitions is viewed from a bird's-eye view. This makes it possible to accurately grasp the environmental condition of the floor and accurately grasp the operational issues of air conditioning equipment and the like related to the floor environment.

The present invention can also be viewed in terms of methods and programs. For example, in the present invention, the computer accepts an input operation of the position of each environmental sensor installed in each part of the floor and an input operation of the position of the partition installed on the floor on the setting screen imagining the floor of the property. From the possible input reception processing and the measured value of the environmental data collected from each environmental sensor, the estimated value of the environmental data between the installation locations of each environmental sensor is interpolated and calculated, and the environmental data of the floor is color-coded according to the value. The contour diagram generation process that generates the contour diagram expressed as based on the measured value, the estimated value, and the position information of each environment sensor received in the input acceptance process is executed, and the contour diagram generation process performs the input acceptance process. When the partition whose position is input in is located between at least one pair of environmental sensors, the area of the contour diagram on one side of the partition is based on the measured value of the environmental sensor on one side. The area from the environmental sensor on one side to the partition is color-coded, and the area of the contour diagram on the other side of the partition is based on the measured value of the environmental sensor on the other side. It may be an indoor environment analysis method in which the area from the environmental sensor in the above to the partition portion is color-coded and expressed.

Further, the present invention is, for example, an input receiving means which is an indoor environment analysis device and can receive an input operation of the position of each environment sensor installed in each part of the floor on a setting screen imagining the floor of the property. , From the measured values of the environmental data collected from each environmental sensor, the estimated value of the environmental data between the installation locations of each environmental sensor is interpolated and calculated, and the contour diagram expressing the environmental data of the floor is color-coded according to the value. An indoor environment analysis device equipped with a contour diagram generating means for generating based on actual measurement values, estimated values, and position information of each environment sensor received by the input receiving means, and the input receiving means is on the floor. In addition to accepting input operations for the position of the installed partition, the contour diagram generation means is a contour diagram that expresses the environmental data of the floor between the partition and each environmental sensor close to the partition in different colors according to the value. May be generated.

With the above indoor environment analysis device, method and program, even if the floor is equipped with partitions, contour diagrams based on the environmental data collected from the sensors discretely arranged on the floor are properly generated. It is possible.

It is an electronic device equipped with a battery or the like that supplies power to the device. For example, data of temperature and humidity at a location where a wireless temperature / humidity sensor 6 is installed is sent to an analyzer 2 through a communication network 3 or a wireless access point 4. be able to. The wireless temperature / humidity sensor 6 is installed at an appropriate position on the floor of the building T for which the indoor environment is to be measured by the analysis system 1. The analysis device 2 includes a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), a communication interface, and the like, and realizes various functional units by executing a computer program.

The analysis device 2 realizes various functional units by executing, for example, a computer program for measuring the indoor environment of the analysis system 1. By executing a computer program for measuring the indoor environment, the analysis device 2 generates, for example, image information such as an input reception unit 21 that accepts various input operations and a contour diagram displayed on the monitor of the analysis device 2. Unit 22 (an example of the "contour diagram generation means" in the present application), and a display processing unit 23 (an example of the "contour diagram display means" in the present application) that displays the image data generated by the arithmetic processing unit 22 on the monitor. ) Is realized.

Hereinafter, the method of using the analysis system 1 and the contents of the analysis processing realized in the analysis system 1 will be described.

When using the analysis system 1 of the present embodiment, first, the initial settings (design of contour diagram) as shown below are performed. FIG. 2 is a diagram showing a first example of a setting screen displayed on the monitor of the analysis device 2. When the analysis device 2 performs the initial setting operation, the monitor of the analysis device 2 has a setting screen G01 in which a graphic display floor N1 simulating the floor of the building T in which the wireless temperature / humidity sensor 6 is installed is arranged in the center. Is displayed. Floor N1 shows the entire floor in the building T. For example, as can be seen in FIG. 2, structures such as pillars provided in the building T, elevators and other lifting devices on which a person rides, etc. , Others are illustrated.

On the setting screen G01, an operation of arranging a graphic display simulating the wireless temperature / humidity sensor 6 at a position corresponding to the wireless temperature / humidity sensor 6 installed on the floor of the building T is performed. FIG. 3 is a diagram showing a second example of a setting screen displayed on the monitor of the analysis device 2. The operator of the analysis device 2 operates various icons with the pointer P on the screen of the setting screen G01, and the building T
A graphic display icon (hereinafter referred to as sensor N2) simulating the wireless temperature / humidity sensor 6 is arranged at a position corresponding to the wireless temperature / humidity sensor 6 actually installed on the floor.

Further, on the setting screen G01, in addition to the operation of arranging the sensor N2, an operation of arranging a graphic display simulating the partition is performed at a position corresponding to the partition installed on the floor of the building T. FIG. 4 is a diagram showing a third example of the setting screen G01 displayed on the monitor of the analysis device 2. The operator of the analysis device 2 operates various icons with the pointer P on the screen of the setting screen G01, and the partition N3 is a graphic display simulating the partition at a position corresponding to the partition actually installed on the floor of the building T. To place. The partition N3 is arranged, for example, at a portion corresponding to a wall of a room provided in a corner of the floor, as indicated by reference numeral R1 in FIG. Further, the partition N3 is arranged, for example, at a portion corresponding to a counter that separates the non-closed spaces as indicated by the reference numerals R3 and R4 in FIG. 4 or the non-closed spaces as indicated by the reference numerals R4 and R5. To. In FIG. 4, each partition N3 is shown in contact with the inner wall surface of the floor forming the outer wall surface of the building T, but the partition N3 is from the inner wall surface of the floor forming the outer wall surface of the building T. It may be separated.

In addition, at the time of initial setting, the operation of setting the correspondence between the sensor N2 arranged on the floor N1 on the setting screen G01 and each wireless temperature / humidity sensor 6 actually installed in each part of the floor of the building T is performed. Will be. FIG. 5 is a diagram showing a fourth example of a setting screen displayed on the monitor of the analysis device 2. When the analysis device 2 performs an operation to call up the signal list screen, the monitor of the analysis device 2 displays a setting screen G02 showing a list of correspondences between the sensor N2 and the wireless temperature / humidity sensor 6. The value in the column displayed as "tag name" on the setting screen G02 indicates a unique identifier given to each of the wireless temperature / humidity sensors 6 installed on the floor of the building T. The wireless temperature / humidity sensor 6 has both a temperature measurement function and a humidity measurement function, and outputs both a temperature measurement value and a humidity measurement value. For this reason, two unique identifiers are set for one wireless temperature / humidity sensor and assigned to the temperature measurement function and the humidity measurement function, respectively. Further, the value in the column displayed as "Signal name" on the setting screen G02 indicates a unique name given to each of the sensors N2 arranged on the floor N1 on the setting screen G01. The signal name consists of a four-digit number assigned to each wireless temperature / humidity sensor and a combination of two letters (temperature or humidity). Further, the value in the column displayed as "current value" on the setting screen G02 indicates the current value of the measured value of the environmental data (temperature and humidity data) measured by the wireless temperature / humidity sensor 6. When the measurement data transmitted from each wireless temperature / humidity sensor 6 is not collected by the analysis device 2, "-" is displayed in the "current value" column of the setting screen G02. The correspondence between each sensor N2 and the wireless temperature / humidity sensor 6 can be changed on the setting screen for each sensor, which is called when any column is selected and operated on the setting screen G02. In the analysis system 1, the correspondence relationship between each environmental data transmitted from each wireless temperature / humidity sensor 6 at individual timings and collected by the analysis device 2 in the May rain type and the position on the floor of the building T is displayed on the setting screen G02. It will be specified by referring to the set correspondence table. The wireless temperature / humidity sensor 6 may further have a function of measuring the _{CO 2 concentration.} The wireless temperature / humidity sensor 6 is _{given a tag name for the CO 2} concentration measurement function, and the signal name is composed of a combination of a four-digit number and two characters (concentration).

The contents of the initial settings are as described above. The input reception unit 21 mainly controls the processing related to the above series of initial settings. When using the analysis system 1, after the above initial settings are made, the measurement of the indoor environment is started. That is, the analyzer 2 issues an operation instruction to the air-conditioning equipment on the floor of the building T, and starts measuring the indoor environment in an environment where the floor air-conditioning is performed. The analysis device 2 collects environmental data transmitted from each wireless temperature / humidity sensor 6 at predetermined time (for example, 10 minutes). When this collection operation is performed by the analysis device 2, the environmental data (for example, temperature, humidity, CO ₂ concentration) transmitted from the wireless temperature / humidity sensor 6 is associated with the tag name, and the analysis system is associated with the collection time. It is stored in a storage device provided in 1 (for example, a recording device built in the analysis device 2 or a data recording server connected to the communication network 3).

FIG. 6 is a first diagram showing an example of a contour diagram displayed on the analysis device 2. When the analysis device 2 performs an operation requesting the display of the contour diagram, the analysis device 2 displays the contour diagram 2D screen G03 generated based on the measured values of the environmental data collected from the wireless temperature / humidity sensor 6. Will be done. Contour diagram The contour diagram of the 2D screen G03 is a color-coded representation of the environmental data of each part of the floor. In the example shown in FIG. 6, the temperature of each part of the floor is a shaded net according to the value. It is expressed by hanging. From the contour FIG. 2D screen G03 shown in FIG. 6, it can be seen that the region R1 has a relatively lower temperature than the other regions R2, R3, R4, and R5. Further, it can be seen that the region R2 has a substantially uniform temperature distribution. Further, it can be seen that the region R3 has a relatively high temperature as a whole as compared with the other regions R1, R2, R4, and R5. Further, it can be seen that the region R4 has a temperature substantially similar to that of the region R2, but is partially affected by the warm air of the region R5. Further, it can be seen that the central portion of the region R5 has a higher temperature than the peripheral portion, and the variation in temperature distribution is relatively larger than that of the regions R1, R2, R3, and R4.

The process of generating the contour diagram of the contour diagram 2D screen G03 is mainly controlled by the arithmetic processing unit 22. The arithmetic processing unit 22 performs the following processing when generating the contour diagram. That is, the arithmetic processing unit 22 installs each sensor N2 based on the actually measured value of environmental data such as the temperature collected from each wireless temperature / humidity sensor 6 and the position information of the sensor N2 set by the initial setting. Interpolate the estimated value of the environmental data between them. Then, the arithmetic processing unit 22 generates a contour diagram in which the environmental data of the floor is color-coded according to the actually measured value or the estimated value. The contour diagram displayed on the screen G03 is a contour diagram at the time specified on the screen G03 (for example, 2017/02/01 15:10). Further, since it is specified that the temperature is displayed in the environmental data on the screen G03, the contour diagram expressed in different colors according to the measured value or the estimated value of the temperature is displayed on the monitor by the display processing unit 23. To. Further, the arithmetic processing unit 22 stores the generated contour diagram as an image file (for example, jpg format) in the storage device in association with the collection time. The storage device is a data recording server in which the analysis device 2 is connected to the communication network 3. At the same time, the arithmetic processing unit 22 creates a contour diagram color-coded according to the measured and estimated values of _{humidity and CO 2 concentration in addition to the temperature, and stores the contour diagram in the data recording server.} As a result, the contour diagram of temperature, humidity and concentration can be easily switched and displayed on the monitor. In this way, the environmental data of the indoor environment is converted into colors (shades in FIG. 6) and displayed. The arithmetic processing unit 22 may generate a contour diagram each time the time is specified on the screen G03, or stores environmental data such as temperature and humidity collected from the wireless temperature / humidity sensor 6 in the data recording server. The contour diagram may be generated each time the image file is stored, and the image file may be stored in the data recording server.

The contour diagram of the contour diagram 2D screen G03 is not limited to the diagram showing the current environmental data. On the contour diagram 2D screen G03, control button CRs with icons for play, pause, fast forward, rewind, fast forward playback, etc. are arranged, and by clicking these icons with the pointer P, the playback state is displayed. It is possible to perform a change operation. Therefore, the operator of the analysis device 2 can, for example, click the play button or the like on the contour diagram 2D screen G03 to display the contour diagram showing the environmental data of the desired date and time on the analysis apparatus 2 as an animation. When these operations are performed by the control button CR of the contour diagram 2D screen G03, the display processing unit 23 stores the image data of the contour diagram at each time generated by the arithmetic processing unit 22 and stored in the storage device from the storage device. Read and output to the monitor of the analyzer 2.

FIG. 7 is an image showing the processing contents of the image data performed when the control button CR is operated. The image data of the contour diagram sequentially generated by the arithmetic processing unit 22 is stored in the storage device provided in the analysis system 1. The contour diagram image data stored in the storage device is generated and stored every 10 minutes, for example. Then, when the control button CR of the contour diagram 2D screen G03 is operated, the analysis device 2 reads out the image data of the contour diagram at each time stored in the storage device and displays it on the monitor. The contour diagram displayed on the monitor changes according to the playback speed and playback direction specified by the operation of the control button CR. For example, if the fast-forward operation is performed with the control button CR, the contour diagram of each time stored in the storage device is read out one after another in chronological order, and the contour diagram displayed on the monitor is several times faster than the actual speed. It is played back several tens of times faster. Further, for example, if the rewind operation is performed with the control button CR, the contour diagram of each time stored in the storage device is read back in order retroactively, and the contour diagram displayed on the monitor is played back in reverse. .. In the analysis system 1 of the present embodiment, since the image data of the contour diagram at each time is stored in the storage device, each wireless temperature / humidity sensor is used when an operation such as fast forward or rewind is performed by the control button CR. It is not necessary to generate a contour diagram based on the environmental data collected from No. 6, and the contour diagram can be immediately displayed at the reproduction speed and the reproduction direction according to the operation content.

The description of the contour FIG. 2D screen G03 will be continued with reference to FIG. 6 again. A 3D display button F1, a data display switching button F2, a color distribution display switching button F3, and a real-time display switching button F4 are arranged on the contour 2D screen G03. The 3D display button F1 is a button operated when the operator of the analysis device 2 wants to display contour diagrams of a plurality of floors hierarchically. Further, the data display switching button F2 is a button operated when it is desired to display or hide the numerical value of the environmental data displayed superimposed on the contour diagram. Further, the color distribution display switching button F3 is a button operated when it is desired to display or hide the color distribution of the contour diagram. Further, the real-time display switching button F4 is a button operated when the operator of the analysis device 2 wants to display the contour diagram displayed on the contour diagram 2D screen G03 in real time. In this way, the environmental data is displayed as a color (or shade) and as a continuous change. The operator of the analysis device 2 can visually and intuitively grasp the indoor environment of the building T, that is, the air conditioning state. Since the operator of the analysis device 2 can visually and intuitively grasp the change in the indoor environment, the analysis device 2 accurately instructs the air conditioning equipment to adjust _{the temperature and humidity of the indoor environment and the CO 2 concentration.} be able to. In addition, the operator can accurately formulate energy management measures.

By the way, each sensor is simply based on the measured value of the environmental data collected from each wireless temperature / humidity sensor 6 and the position information of the sensor N2, without performing any special arithmetic processing on the partition installed on the floor. When the estimated value of the environmental data between the installation locations of N2 is interpolated and calculated, the following contour diagram is generated. FIG. 8 is a diagram showing an example of a contour diagram according to a comparative example. The partition of each sensor N2 is simply based on the measured value of the environmental data collected from each wireless temperature / humidity sensor 6 and the position information of the sensor N2, without performing any special arithmetic processing on the partition installed on the floor. When interpolating the estimated value of the environmental data between the installation locations, the airflow blocking effect exerted by the partition is not taken into consideration in the interpolation calculation. Is not expressed. That is, the estimated value of the environmental data in the partition portion has almost the same value in both side portions sandwiching the partition. Therefore, in the contour diagram generated using such an estimated value, for example, as shown in FIG. 8, the boundary of the partition partitioning the regions R1, R2, R3, R4, and R5 is ambiguous. It is objectively clear that such contour diagrams differ from the distribution of actual environmental data. Therefore, when such a contour diagram is displayed on the monitor of the analysis device 2, the operator of the analysis device 2 misunderstands the environmental condition of the floor of the building T, or causes an operational problem such as air conditioning equipment on a specific floor. It may be overlooked. Therefore, in the analysis system 1 of the present embodiment, the following processing is performed in the processing of generating the contour diagram.

<First example of division processing by partition>
FIG. 9 is a first diagram showing an outline of internal processing when generating a contour diagram. For example, it is assumed that the locations indicated by the reference numerals P01 to P11 in FIG. 9 are the locations where the sensor N2 is arranged by the initial setting. Then, it is assumed that the region in which the reference numerals P09 to P11 are arranged is separated from the area in which the reference numerals P01 to P08 are arranged by a partition. When the sensor N2 and the partition N3 are set to such a positional relationship in the initial setting, the arithmetic processing unit 22 extracts, for example, the sensor N2 closest to the partition from the plurality of sensors N2 arranged on P01 to P11. Processing is performed.

FIG. 10 is a second diagram showing an outline of internal processing when generating a contour diagram. As a process of extracting the sensor N2 closest to the partition from the plurality of sensors N2 arranged on P01 to P11, for example, the shortest distance from each sensor N2 to the partition is calculated for all of P01 to P11, and among them. One example is the process of extracting the ones that are relatively close to each other. For example, if the positional relationship between the sensors N2 arranged on P01 to P11 and the partition is as shown in FIG. 9, the sensor N2 closest to the partition is as shown in FIG. , P04 to P11 are extracted.

FIG. 11 is a third diagram showing an outline of internal processing when generating a contour diagram. After the process of extracting the sensor N2 closest to the partition is performed, the process of setting virtual sensors (P21 to P24, P27 to P30) at positions close to the sensor N2 in the partition is performed. In addition, the locations where the sensors N2 are arranged (P01 to P11), the locations where the virtual sensors are set (P21 to P24, P27 to P30), and the locations that serve as the start and end points of the partition (P25 and 26) are designated. A process to generate polygons by setting as nodes of the display model used for displaying contour diagrams and arranging triangular areas (hereinafter referred to as "tiles") defined by a grid (broken line in FIG. 11) connecting each node vertically and horizontally. Is done.

FIG. 12 is a fourth diagram showing an outline of internal processing when generating a contour diagram. After the process of generating the polygon is performed, the process of calculating the estimated value of the environmental data at each node of the polygon is performed. The estimated value of the environmental data in each virtual sensor is calculated using the environmental data of the sensors N2 actually arranged in the vicinity. For example, the environmental data of the virtual sensor arranged on P22 is estimated to be the same value as the environmental data of the sensor N2 arranged on the nearest P06. The values of the environmental data of the virtual sensors arranged at P21, P24, P27, and P28 are estimated in the same manner as the values of the environmental data of the virtual sensors arranged at P22. Further, for example, the values of the environmental data of the virtual sensors arranged at the locations (P26) surrounded by the three locations (P04, P05, P07) are, for example, the sensors N2 arranged at P04, P05, and P07, respectively. It is estimated to be the average value of the environmental data of. Further, the value of the environmental data at the end (start point or end point) of the partition located at the position (P25) between the two locations (P23, P28) is, for example, the value of the environmental data of the sensors N2 arranged at P23 and P28, respectively. Estimated to be the average value of environmental data.

After all the environmental data values (measured values and estimated values) at each node of the polygon are calculated, the interpolation calculation of the environmental data in each tile of the polygon is performed, and the pattern is followed by the values calculated by the interpolation calculation. Graphic data with painting (gradation) that changes continuously is generated for each tile. Then, polygons in which the generated graphic data is fitted into each tile are displayed as contour diagrams.

<Second example of division processing by partition>
FIG. 13 is a fifth diagram showing an outline of internal processing when generating a contour diagram. As the internal processing when generating the contour diagram, the mode of the second example shown below may be applied instead of the mode of the first example described above. That is, as the process of determining the position of the virtual sensor in the partition, in addition to the process of determining the position of the virtual sensor in the partition, for example, the intermediate point of the pair of nearby sensors N2 is set as the position of the virtual sensor in the partition. The process of determining is mentioned. For example, the shortest distance from each sensor N2 to the partition is calculated for all of P01 to P11, and after the process of extracting those having a relatively short distance from them is completed, the intermediate point of each extracted sensor N2 is partitioned. Determined as the position of the virtual sensor in.

For example, if the positional relationship between the sensors N2 arranged on P01 to P11 and the partition is as shown in FIG. 9, the sensors N2 closest to the partition are arranged on P04 to P11. What is is extracted. Therefore, for example, when the position of the partition which is the intermediate point when viewed from each position (P04 to P11) of the extracted sensor N2 is determined, if it is the intermediate point between P05 and P06 in the partition, it is shown in FIG. As described above, P42 is determined as the position of the virtual sensor. P41, P45, and P46 shown in FIG. 13 are also determined in the same manner as P42.

FIG. 14 is a sixth diagram showing an outline of internal processing when generating a contour diagram. After the process of determining the position of the virtual sensor in the partition is performed, the location where the sensor N2 is arranged (P01 to P11), the location where the virtual sensor is set (P41, P42, P45, P46), and The start and end points (P43, 44) of the partition are set as the nodes of the display model used for displaying the contour diagram, and the triangular tiles defined by the grid connecting each node (broken line in FIG. 14) are arranged vertically and horizontally. The process of generating the arranged polygons is performed.

FIG. 15 is a seventh diagram showing an outline of internal processing when generating a contour diagram. After the process of generating the polygon is performed, the process of calculating the estimated value of the environmental data at each node of the polygon is performed. In this second example as well, as in the first example, the estimated value of the environmental data in each virtual sensor is calculated using the environmental data of the sensors N2 actually arranged in the vicinity, but the calculation method is It is slightly different from the first example above. In this second example, since each virtual sensor is arranged at an intermediate point between neighboring real sensors, the intermediate value of the measured values indicated by the pair of real sensors is adopted as the estimated value of the environmental data in the virtual sensor. To. For example, the environmental data of the virtual sensor arranged on P42 is estimated to be an intermediate value of the environmental data values of the respective sensors N2 arranged on P06 and P05 nearby. As the intermediate value, the value obtained by dividing the total value of the environmental data value of the sensor N2 arranged on P05 and the environmental data value of the sensor N2 arranged on P06 by 2 (that is, the average value) is taken. Alternatively, a value corresponding to the difference between the distance from P05 to the virtual sensor and the distance from P06 to the virtual sensor may be taken. When the former average value is taken, as shown in FIG. 15, the value of the environmental data of the sensor N2 on P05 is "19.2 ° C", and the value of the environmental data of the sensor N2 on P06 is "18.9 ° C". If ", the estimated value of the environmental data of the virtual sensor on P42 is" 19.1 ° C. ", which is the average value of both.

After all the environmental data values (measured values and estimated values) at each node of the polygon are calculated, the interpolation calculation of the environmental data in each tile of the polygon is performed as in the first example above, and the calculation is performed by the interpolation calculation. Painted graphic data in which the pattern changes continuously according to the set values is generated for each tile. Then, polygons in which the generated graphic data is fitted into each tile are displayed as contour diagrams.

<Third example of division processing in partition>
FIG. 16 is an eighth diagram showing an outline of internal processing when generating a contour diagram. In the third example, a case where the partition does not form a closed space as in the first and second examples but is a mere optotype will be described as an example. That is, although the sensor N2 is initially arranged at the locations indicated by the reference numerals P01 to P11 in FIG. 16 as in the first example and the second example, the region where the reference numerals P01 to P06 are arranged and the reference numerals P07 It is assumed that the partition between the regions where ~ P11 is arranged does not separate the two regions. When the sensor N2 and the partition N3 are set to such a positional relationship in the initial setting, the arithmetic processing unit 22 extracts, for example, the sensor N2 closest to the partition from the plurality of sensors N2 arranged on P01 to P11. Processing is performed.

FIG. 17 is a ninth diagram showing an outline of internal processing when generating a contour diagram. When the process of extracting the sensor N2 closest to the partition is performed from the plurality of sensors N2 arranged on P01 to P11, for example, as shown in FIG. 17, P04 to P7, P09 as the sensor N2 closest to the partition. , P11 are extracted. Then, a process of determining the intermediate point of each extracted sensor N2 as the position of the virtual sensor in the partition is performed. In the example shown in FIG. 17, among the locations (P04 to P7, P09, P11) extracted as the sensor N2 closest to the partition, the intermediate point P52 between P05 and P06 in the partition and the middle between P09 and P11 in the partition. The point P51 is determined as the position of the virtual sensor.

FIG. 18 is a tenth diagram showing an outline of internal processing when generating a contour diagram. After the process of determining the position of the virtual sensor in the partition is performed, the location where the sensor N2 is arranged (P01 to P11), the location where the virtual sensor is set (P51, P52), the starting point of the partition, and the like. The end point (P53) is set as a node of the display model used for displaying the contour diagram, and a polygon in which triangular tiles defined by a grid connecting each node (broken line in FIG. 18) is arranged vertically and horizontally is generated. Processing is done.

FIG. 19 is an eleventh diagram showing an outline of internal processing when generating a contour diagram. After the process of generating the polygon is performed, the process of calculating the estimated value of the environmental data at each node of the polygon is performed. In the third example as well, as in the first and second examples, the estimated value of the environmental data in each virtual sensor is calculated using the environmental data of the sensors N2 actually arranged in the vicinity. Further, as the value of the environmental data at the end of the partition, basically the same as in the first and second examples, for example, the average value of the environmental data of the sensors N2 actually arranged in the vicinity is used. The peculiar point of this third example is that the number of environmental data of the neighboring sensor N2 referred to when calculating the value of the environmental data at the end of the partition is larger than that of the first and second examples. is there. That is, while the environmental data values of the partition ends in the first and second examples are the average values of the environmental data values of the two neighboring sensors N2, the partition ends in the third example are taken. As the value of the environmental data of the unit, as shown in FIG. 19, the average value of the environmental data values of the four sensors N2 located at four locations (P05, P04, P07, P09) in the vicinity of the partition end is taken.

After all the environmental data values (measured values and estimated values) at each node of the polygon are calculated, the interpolation calculation of the environmental data in each tile of the polygon is performed as in the first and second examples above. Painted graphic data in which the pattern changes continuously according to the value calculated by the interpolation calculation is generated for each tile. Then, polygons in which the generated graphic data is fitted into each tile are displayed as contour diagrams.
