However, the present invention is not limited to the embodiment.

[0022] [I] Basic Concept of the Embodiment First, the basic concept of the embodiment will be described. The embodiment relates to a management system. The management system according to the present invention is a system for managing a target site, and the concept includes, for example, a dedicated system for managing the target site, or a system realized by implementing a function for managing the target site in a system equipped with various general-purpose computers (for example, a server, a personal computer, a mobile terminal such as a smartphone, etc.).

[0023] The term "target site" refers to a site that is managed using the management system, and is a concept that includes, for example, a construction site and any site other than a construction site.

[0024] In the following embodiment, the case where the "target site" is a construction site will be described.

[0025] [II] Specific Contents of Each Embodiment Next, specific contents of each embodiment will be described.

[0026] (Configuration) First, the configuration of the management system according to this embodiment will be described. Fig. 1 is a diagram showing the overall configuration of the management system, and Fig. 2 is a diagram showing an example of a construction site.

[0027] 1 illustrates construction sites A to C, but the management system 900 may also be applied to other construction sites. For the sake of convenience, the components (sensor device 1 and on-site terminal 2) installed at construction sites B and C are not shown in the figure.

[0028] "Construction sites" A to C are target sites, and are sites where any construction work, such as building construction or demolition work, is being carried out. As shown in Figure 2, each of the construction sites A to C is surrounded by a temporary fence set up at the boundary between the inside and outside of the construction site, and heavy construction machinery and the like are also installed. When the heavy machinery is in operation, it may generate vibrations and noise.

[0029] The management system 900 in FIG. 1 is a system for managing construction sites A to C, and includes, for example, a sensor device 1, a site terminal 2, and a server device 3.

[0030] (Configuration - Sensor Device) Fig. 3 is a block diagram showing a sensor device. The sensor device 1 in Fig. 1 is a measurement device. Note that any number of sensor devices 1 may be installed at each construction site (only one may be installed, but installing multiple devices will improve accuracy, etc.), but in this embodiment, the description will focus on the sensor devices 101 and 102 installed at construction site A. Note that when there is no need to distinguish between the sensor devices 101, 102, etc., they will be collectively referred to as sensor device 1.

[0031] The "measuring device" is, for example, a device that measures physicochemical quantities at a target site, is installed at the target site, and transmits first physicochemical quantity information, which is information corresponding to the physicochemical quantities measured by the measuring device, to the on-site device. This "measuring device" may be configured to be able to perform any processing (such as calculations related to the measured data, communication processing, etc.) in addition to the measurement.

[0032] "Physicochemical quantity" is a concept that indicates a physical quantity or a chemical quantity, and includes, for example, the magnitude of noise, the magnitude of vibration, dust, odor, amount of light, temperature, humidity, the concentration of a specific gas (toxic gas, etc.), etc. In this embodiment, a case will be described in which the "physicochemical quantity" is the magnitude of noise (i.e., noise) and the magnitude of vibration (i.e., vibration).

[0033] Specifically, the sensor device 1 in FIG. 1 is a device that continuously and repeatedly measures noise and vibration over time, and includes, for example, a communication unit 11, a measurement unit 12, a recording unit 13, and a control unit 14, as shown in FIG. 3.

[0034] (Configuration - Sensor device - Communication unit) The communication unit 11 in Figure 3 is a communication means for communicating with an external device (for example, a site terminal 2 within the same construction site), and can be configured using, for example, any communication circuit, etc. (the same applies to the communication units of other devices).

[0035] (Configuration - Sensor Device - Measurement Unit) The measurement unit 12 in Figure 3 is a measurement means that continuously and repeatedly measures noise and vibration over time, and can be configured using, for example, any noise sensor (including a sound sensor, etc.) and vibration sensor.

[0036] In this embodiment, an example is given in which noise and vibration are measured using one sensor device 1, but the sensor devices 1 may be divided into two types, one dedicated to noise and one dedicated to vibration.

[0037] (Configuration - Sensor device - Recording unit) The recording unit 13 in Figure 3 is a recording means for recording programs and various data necessary for the operation of the sensor device 1, and is configured using, for example, a flash memory as an internal recording device or an external recording device (the same applies to the recording units of other devices).

[0038] 3 is a control means for controlling the sensor device 1, and is specifically a computer including a CPU, various programs interpreted and executed on the CPU (including basic control programs such as an OS and application programs that are started on the OS and realize specific functions), and an internal memory such as RAM for storing programs and various data (the same applies to the control units of other devices). In particular, the program according to the embodiment is installed in the sensor device 1 via an arbitrary recording medium or a network, thereby substantially configuring each unit of the control unit 14 (the same applies to the control units of other devices).

[0039] (Configuration - Site Terminal) Fig. 4 is a block diagram showing a site terminal. The site terminal 2 in Fig. 1 is a site device. Note that any number of site terminals 2 may be provided at each construction site, but in this embodiment, the description will focus on the site terminal 2 provided at construction site A.

[0040] A "field device" is, for example, a device that performs field management processing to manage a target field based on the measurement results of a measuring device, and is installed at the target field (for example, installed in any building (temporary building, etc.) on the site (construction site, etc.)), and performs field management processing based on first physicochemical quantity information from the measuring device.

[0041] As shown in FIG. 4, the on-site terminal 2 in FIG. 1 includes, for example, a communication unit 21, a recording unit 22, and a control unit 23.

[0042] (Configuration - Site Terminal - Components) The communication unit 21 in FIG. 4 is a communication means for communicating with external devices (for example, the server device 3 and the sensor device 1 within the same construction site).

[0043] The recording unit 22 in FIG. 4 is a recording means for recording programs and various data required for the operation of the on-site terminal 2 .

[0044] The control unit 23 in FIG. 4 is a control means for controlling the on-site terminal 2 .

[0045] (Configuration - Server Device) Figure 5 is a block diagram showing a server device. The server device 3 in Figure 1 is another device. The location of the server device 3 is arbitrary, and for example, it may be installed at any construction site, or it may be installed at any location other than a construction site (such as a data center). The server device 3 may also be configured as a cloud computer consisting of multiple computers distributed across multiple locations.

[0046] "Other devices" refers to, for example, any devices other than the sensor device 1 and the on-site terminal 2 in the management system 900, and includes, as an example, a server device 3, and as a variation, a concept that includes user terminals (personal computers owned by users working at each construction site (i.e., computers assigned to users)), etc.

[0047] The server device 3 in FIG. 1 is a device for managing the construction sites A to C, etc., and includes, for example, a communication unit 31, a recording unit 32, and a control unit 33 as shown in FIG.

[0048] (Configuration - Site Terminal - Each Unit) The communication unit 31 in FIG. 5 is a communication means for communicating with an external device (for example, the site terminal 2 in each construction site).

[0049] The recording unit 32 in FIG. 5 is a recording means for recording programs and various data required for the operation of the server device 3 .

[0050] The control unit 33 in FIG. 4 is a control means for controlling the server device 3 .

[0051] (Processing) Next, the processing executed by the management system 900 according to this embodiment will be described. For example, information storage processing, terminal-side cause-related processing, and server-side cause-related processing will be described. Note that unless a processing entity is specified in the following processing, the control unit of each device will be the processing entity.

[0052] (Processing - Information Storage Processing) First, the information storage processing will be described. Fig. 6 is an explanatory diagram of various data. The "information storage processing" is a processing in which each device included in the management system 900 stores data based on data measured by the sensor device 1.

[0053] ===Data=== Note that in this information storage process, the data shown in the "Data" column in Fig. 6 is used. Note that the characteristics of each piece of data are as described in the "Explanation" column in Fig. 6.

[0054] 6 refers to information indicating the measurement results of noise and vibration measured repeatedly and continuously over time by the sensor device 1, and is, for example, data indicating noise and vibration measured at time intervals (e.g., 0.001 seconds) that are sufficiently shorter than a predetermined time (e.g., 0.1 seconds). In other words, the "raw data" refers to data corresponding to the raw waveforms of the measurement results.

[0055] 6 is data based on raw data, and is, for example, data having less information than raw data. The term "less information than raw data" refers to a concept indicating, for example, a small amount of information for a certain period of time (for example, 10 minutes), and may be interpreted as indicating a small number of pieces of data.

[0056] In this embodiment, the first data is data corresponding to a part of the raw data, for example, data at a predetermined time interval (0.1 seconds).

[0057] 6 is data based on the first data and has less information than the first data. The phrase "having less information than the first data" refers to a concept that indicates, for example, a small amount of information for a certain period of time (e.g., 10 minutes), and may be interpreted as indicating a small number of pieces of data.

[0058] In this embodiment, the second data is data corresponding to a part of the first data, and is data at a predetermined time interval (10 seconds), for example.

[0059] Processing <Sensor Device> Specifically, regarding processing, first, the sensor device 1 in Figure 1 measures noise and vibration using the measurement unit 12 in Figure 3, generates raw data indicating the measurement results, and stores and accumulates the generated raw data in its own recording unit 13.

[0060] In addition, the sensor device 1 in Figure 1 performs arithmetic processing (e.g., data filtering, statistical processing, or thinning out some of the data) on the raw data it generates, to generate first data (e.g., data indicating noise and vibration at 0.1 second intervals), and repeatedly performs the process of transmitting the generated first data to the on-site terminal 2.

[0061] In this case, the sensor device 1 transmits the first data together with the sensor ID set for itself. By transmitting the sensor ID in this manner, it becomes possible to identify which sensor device 1's measurement results the data is based on.

[0062] <Field terminal> Next, the field terminal 2 in Figure 1 receives and acquires the first data and sensor ID transmitted by the sensor device 1, and stores and accumulates the acquired first data and sensor ID in its own recording unit 22 in a state in which they are mutually associated.

[0063] In addition, the on-site terminal 2 in Figure 1 performs calculations (e.g., data filtering, statistical processing, or thinning out some of the data) on the first data received from the sensor device 1 to generate second data (e.g., data indicating noise and vibration at 10-second intervals), and repeatedly performs the process of transmitting the generated second data to the server device 3.

[0064] In this case, the on-site terminal 2 transmits the second data together with the terminal ID set therein and the above-mentioned sensor ID. By transmitting the terminal ID and the sensor ID in this manner, it becomes possible to know which sensor device 1's measurement results the data is based on and which on-site terminal 2 transmitted the data from.

[0065] <Server device> Next, the server device 3 in Figure 1 receives and acquires the second data, sensor ID, and terminal ID transmitted by the on-site terminal 2, and stores and accumulates the acquired second data, sensor ID, and terminal ID in its own recording unit 32 in a state in which they are associated with each other.

[0066] ===Interpretation of Terms=== Note that the processing executed by the on-site terminal 2 or the server device 3 here may be interpreted as corresponding to "site management processing" (i.e., processing for managing the target site).

[0067] (Processing - Terminal-side Cause-Related Processing) Next, the terminal-side cause-related processing will be described. "Terminal-side cause-related processing" is a site management processing, such as processing to determine whether or not a noise or vibration causing factor exists at a construction site, or to identify one or both of the causing factors, and is processing executed by the site terminal 2. Here, for example, a case will be described in which the site terminal 2 at construction site A is the processing subject when identifying both of the above.

[0068] ===Premise=== It is assumed that construction information for the corresponding construction site (the construction site where the site terminal 2 is installed) is stored in the recording unit 22 of the site terminal 2 at construction site A. "Construction information" is information related to the construction work being carried out at the construction site, and is a concept that includes, for example, information indicating the construction process (information indicating the planned period and time period for each task), information indicating the building that will be the target of the construction work, information indicating the equipment (heavy machinery, etc.) used in the construction work or the range of the installation location of the equipment, information indicating the type of equipment (heavy machinery, etc.) and the content of the work, information indicating the installation location of the sensor device 1 (the construction site where it is installed and the installation location within the construction site), information indicating the construction conditions and construction method, local information such as ground conditions, surrounding area information (zoning, building use, etc.), etc.

[0069] Here, we will explain an example in which construction information is used, for example, information indicating the construction process (information indicating the planned time period for each task to be carried out, etc.) and information indicating the installation location of the sensor device 1 (the location where it is installed within the construction site).

[0070] ===Processing=== In general, as explained in the information storage process above, the on-site terminal 2 receives first data (data indicating noise and vibration at 0.1 second intervals) from each sensor device 1, and performs processing using the first data and construction information.

[0071] Specifically, first, the noise level indicated by the first data is compared with a noise threshold (a value predetermined for judgment), and then the vibration level indicated by the first data is compared with a vibration threshold (a value predetermined for judgment).

[0072] The comparison here may be configured to compare a statistical value such as the average, moving average, or median of the noise loudness over a recent specified time period with the noise threshold, or may be configured to compare one or more recent noise loudness values ​​with the noise threshold (the same applies to comparisons in other processes).

[0073] If the noise level is less than the noise threshold and the vibration level is less than the vibration threshold, the above-described comparison process is performed again.

[0074] On the other hand, if the noise level is above the noise threshold or the vibration level is above the vibration threshold, the information indicating the construction progress is referred to and, based on whether the current time (the current time determined by a timing means such as a timer on the on-site terminal 2) falls within the time period during which any work is scheduled to be carried out, it is determined whether a cause of noise or vibration exists at the construction site.

[0075] For example, if the current time falls within the time period when any work is scheduled to be carried out, the cause of the noise or vibration is determined to be present at the construction site, and on the other hand, if the current time does not fall within the time period when any work is scheduled to be carried out (i.e., the current time is during a time period when no work is scheduled to be carried out), the cause of the noise or vibration is determined to be not present at the construction site (i.e., it is determined to be present outside the construction site).

[0076] Next, if it is determined that the cause of the noise or vibration is present at the construction site, the installation positions of the sensor devices 101, 102, etc. in Figure 1 within the construction site A are determined based on the information indicating the installation positions of the sensor device 1, and then the location of the heavy equipment that is causing the noise or vibration is determined taking into consideration the magnitude of the noise or vibration indicated by the first data and the determined installation positions. Any specific determination method may be used, but for example, a determination method may be used that focuses on the fact that the magnitude of noise and vibration attenuates with distance.

[0077] Here, for example, it is possible to configure the system so that the location of each heavy machine can be identified using GPS signals, etc., and after identifying the heavy machine that is at the identified location as the cause of the above-mentioned occurrence, an alert (warning) is output to the identified heavy machine (the same applies to similar processing described below).

[0078] (Processing - Server-Side Cause-Related Processing) Next, the server-side cause-related processing will be described. The "server-side cause-related processing" is a site management processing that determines whether or not a noise or vibration causing factor exists at a construction site and identifies the causing factor, and is a processing that is executed by the server device 3.

[0079] This server-side cause-related processing is processing similar to the terminal-side cause-related processing described above, but performed on the server device 3 side using the second data.

[0080] ====Assumptions= ...

[0081] ===Processing=== In general, as explained in the information storage process above, the server device 3 receives second data (data indicating noise and vibration at 10-second intervals) from the site terminal 2, and performs processing using the second data and construction information.

[0082] Specifically, the noise level indicated by the second data is first compared with the noise threshold, and the vibration level indicated by the second data is also compared with the vibration threshold. Then, by performing processing similar to the terminal-side cause-related processing, it is determined whether a cause of noise or vibration exists at the construction site, and the location of the heavy machinery that is causing the noise or vibration is identified.

[0083] That is, if the magnitude of the noise is less than the noise threshold and the magnitude of the vibration is less than the vibration threshold in the above comparison process, the above comparison process is executed again.

[0084] On the other hand, if the noise level is above the noise threshold or the vibration level is above the vibration threshold, the information indicating the construction process is referenced and whether or not a cause of noise or vibration exists at the construction site is determined based on whether or not the current time (the current time determined by a timing means such as a timer in the server device 3) falls within the time period during which any work is scheduled to be carried out.

[0085] For example, if the current time falls within the time period when any work is scheduled to be carried out, the cause of the noise or vibration is determined to be present at the construction site, and if the current time does not fall within the time period when any work is scheduled to be carried out, the cause of the noise or vibration is determined to be not present at the construction site (i.e., it is determined to be present outside the construction site).

[0086] Next, if it is determined that the cause of the noise or vibration is present at the construction site, the location of the heavy equipment that is causing the noise or vibration is identified by performing processing similar to the terminal-side cause-related processing.

[0087] (Effects of the Present Embodiment) According to the present embodiment, the on-site terminal 2 performs on-site management processing based on the first data (first physicochemical quantity information) from the sensor device 1, thereby making it possible to appropriately manage, for example, the construction site A. In particular, for example, since the on-site terminal 2 is the processing main body, it is possible to reduce the load on the server device 3 (a device for managing multiple construction sites A to C, etc.) if such a device is used. Furthermore, for example, since the on-site terminal 2 is provided at the construction site A, maintenance of the on-site terminal 2 is facilitated, making it possible to efficiently and appropriately manage the construction site A.

[0088] [III] Modifications to the Embodiments The embodiments of the present invention have been described above, but the specific configurations and means of the present invention can be modified and improved as desired within the scope of the technical ideas of each invention as set forth in the claims. Such modifications will be described below.

[0089] (Regarding the problems to be solved and the effects of the invention) First, the problems to be solved by the invention and the effects of the invention are not limited to those described above, and may differ depending on the implementation environment of the invention and the details of the configuration, and may solve only some of the problems described above or achieve only some of the effects described above.

[0090] (Regarding distribution and integration) Furthermore, the components described above are functional concepts and do not necessarily need to be physically configured as shown in the drawings. In other words, the specific form of distribution and integration of each part is not limited to that shown in the drawings, and all or part of them can be functionally or physically distributed or integrated in any unit depending on various loads, usage conditions, etc. Furthermore, some elements in the management system 900 (for example, the server device 3 or the on-site terminal 2) may be omitted.

[0091] (Regarding Shape, Numerical Values, Structure, and Time Series) The shapes, numerical values, or interrelationships between the structures or time series of the components illustrated in the embodiments and drawings can be modified and improved as desired within the scope of the technical concept of the present invention. For example, the numerical values ​​such as measured values ​​or set values ​​described in this application are given for convenience.

[0092] (Regarding Image Data) The terminal-side cause-related processing described in the above embodiment may also be configured to take image data into consideration. For example, an imaging device (a device that captures image data such as still images or videos) may be installed at the construction site, and the on-site terminal 2 may acquire image data captured by the imaging device and automatically determine the situation within the construction site based on the acquired image data (e.g., automatic determination using AI technology). The obtained heavy equipment information, position, and operation information for the situation within the construction site may be processed in combination with measured noise and vibration data (i.e., first data), thereby improving processing accuracy. This image data may be stored in the on-site terminal 2, or may be transmitted to the server device 3 and stored there. Furthermore, for example, the construction information stored in the server device 3 (information indicating the building to be constructed, information indicating the equipment (e.g., heavy equipment) used in the construction or the range of the installation location of the equipment, information indicating the installation location of the sensor device 1 (the construction site where it is installed and its location within the construction site), etc.) may be updated based on the results of automatic determination from the image data, etc.

[0093] (Regarding Alarms) Furthermore, in relation to the server-side cause-related processing described in the above embodiment, the server device 3 may be configured to output an alarm regarding noise or vibration.

[0094] For example, the noise level indicated by the second data may be compared with a noise threshold, and if the noise level exceeds the noise threshold, warning information indicating that the noise has exceeded the expected level may be output. Alternatively, the noise level may be determined based on the analysis results by identifying a trend in the noise level indicated by the second data over time (e.g., an increasing trend, a flat trend, a decreasing trend, etc.), and if an increasing trend is identified in which the noise will exceed the noise threshold within a predetermined time, warning information (advance warning information) indicating that the noise is likely to exceed the expected level may be output.

[0095] It should be noted that the same processing as for noise may be performed for vibration as well.

[0096] The method for outputting the alarm information is arbitrary, but for example, the alarm information may be displayed on a web page accessible to the user, or the alarm information may be sent to a terminal device used by the user and output, or the alarm information may be output to the corresponding on-site terminal 2 at the site, and output as sound or light via a speaker or alarm lamp installed at the site.

[0097] (Regarding Cooperation (Part 1)) The server device 3 and the on-site terminal 2 may be configured to cooperate with each other to perform processing.

[0098] First, with regard to the server-side cause-related processing described in the above embodiment, the server device 3 compares the noise and vibration magnitude indicated by the second data with the noise threshold and vibration threshold, and if the noise magnitude is equal to or greater than the noise threshold, or if the vibration magnitude is equal to or greater than the vibration threshold, requests the on-site terminal 2 (the on-site terminal 2 that transmitted the second data indicating noise equal to or greater than the noise threshold, or the on-site terminal 2 that transmitted the second data indicating vibration equal to or greater than the vibration threshold) to transmit the first data (Figure 6).

[0099] Next, the on-site terminal 2 that has received the transmission request transmits the first data to the server device 3 .

[0100] Next, the server device 3 receives and acquires the first data transmitted by the on-site terminal 2, compares the noise level indicated by the acquired first data with the noise threshold value, and also compares the vibration level indicated by the first data with the vibration threshold value (i.e., performs the comparison process again).Then, by performing a process similar to the terminal-side cause-related process, it determines whether a cause of noise or vibration exists at the construction site, and also identifies the location of the heavy machinery that is causing the noise or vibration.

[0101] By configuring in this way, it is possible to reliably identify the cause of the problem while normally maintaining the amount of communication (the amount of communication between the on-site terminal 2 and the server device 3) at a relatively small amount.

[0102] The processing performed by the server device 3 and the on-site terminal 2 described here may be construed as corresponding to the "on-site management processing."

[0103] (Regarding Collaboration (Part 2)) Furthermore, "(Regarding Collaboration (Part 1))" may be changed as desired. For example, the server device 3 may be configured to, after receiving and acquiring the first data transmitted by the on-site terminal 2, identify whether a cause of noise or vibration is present at the construction site without performing a comparison process, and also identify the location of the heavy machinery that is causing the noise or vibration.

[0104] (Regarding Abnormalities in the Sensor Device) The sensor device 1 may also be configured to detect abnormalities in the sensor device 1. For example, as described in the information storage process of the embodiment, the recording unit 22 of the on-site terminal 2 stores information in which the first data and the sensor ID are mutually combined, and the recording unit 32 of the server device 3 stores information in which the second data, the sensor ID, and the terminal ID are mutually combined, so the sensor device 1 may be configured to utilize this information.

[0105] For example, the on-site terminal 2 refers to its own recording unit 22 and detects an abnormality in the sensor device 1 based on whether information at expected time intervals (0.1 second intervals) is stored as the first data. If the expected time interval information is stored as the first data, the on-site terminal 2 does not detect an abnormality in the sensor device 1. On the other hand, if the expected time interval information is not stored as the first data (for example, if the time interval is wider than expected or if no information is stored at all), the on-site terminal 2 detects an abnormality in the sensor device 1 corresponding to the first data. If an abnormality is detected, the on-site terminal 2 outputs alarm information indicating that an abnormality has been detected.

[0106] Furthermore, for example, the server device 3 also performs the same processing as the on-site terminal 2. Specifically, the server device 3 refers to its own recording unit 32 and detects an abnormality in the sensor device 1 based on whether information at the expected time interval (10-second interval) is stored as the second data. If the expected time interval information is stored as the second data, the server device 3 does not detect an abnormality in the sensor device 1. On the other hand, if the expected time interval information is not stored as the second data, the server device 3 detects an abnormality in the sensor device 1 corresponding to the second data. If an abnormality is detected, the server device 3 outputs alarm information indicating that an abnormality has been detected.

[0107] In addition, the on-site terminal 2 and the server device 3 may be configured to output alarm information indicating that an abnormality in the sensor device 1 has been detected only when both the on-site terminal 2 and the server device 3 detect an abnormality in the common sensor device 1.

[0108] (Regarding Fail-Safe Processing) The server device 3 and the on-site terminal 2 may be configured to perform fail-safe processing related to the management system 900. The term "fail-safe processing" is a concept that indicates processing to deal with a failure that occurs in some element of the management system 900, with the aim of reducing the degree of adverse effects caused by the failure or eliminating the adverse effects.

[0109] For example, if the second data cannot be stored on the server device 3 side due to a failure on the server device 3 side or a communication failure (a communication failure between the server device 3 and the on-site terminal 2), the server device 3 will, after recovery, refer to its own recording unit 32 and determine that the expected time interval information is not stored in the stored second data. In this case, the server device 3 requests the on-site terminal 2 to transmit the necessary data (the second data corresponding to the time period that would have been stored if the failure had not occurred).

[0110] Meanwhile, the on-site terminal 2 generates the requested necessary data based on the first data stored in the recording unit 22 and transmits the generated necessary data to the server device 3. The server device 3 receives the necessary data and records it in the recording unit 32, thereby being able to store the expected time interval information as the second data.

[0111] For example, the on-site terminal 2 can check the communication status between itself and the server device 3, thereby making it possible for the on-site terminal 2 to grasp the occurrence and recovery of the above-mentioned failure. In this case, the second data that should have been sent during the failure period (the second data that could not be sent to the server device 3 due to the failure) can be recorded, and the recorded second data can be sent together to the server device 3 after the failure is recovered.

[0112] (Regarding terminal-side cause-related processing (part 1)) In addition, in the terminal-side cause-related processing described in the above embodiment, the following processing may be configured to be performed to determine whether or not a noise or vibration causing factor is present at the construction site.

[0113] == ...

[0114] Regarding the processing, the on-site terminal 2 may be configured to identify whether or not a cause of occurrence exists at the construction site based on the construction information recorded in the recording unit 22, the past first data accumulated in the recording unit 22, and the most recently received first data. In this case, the on-site terminal 2 may be configured to perform processing using a trained model generated by performing predetermined machine learning. The same applies to the processing for identifying the cause of occurrence. In this case, the on-site terminal 2 may be configured to identify the type of heavy equipment that is the cause of occurrence, or may be configured to identify the heavy equipment itself based on the identified type. The server-side cause-related processing may also be configured in a similar manner.

[0115] (Processing related to factors causing noise or vibration on the terminal side (part 2)) Furthermore, for example, if a factor causing noise or vibration is present at a construction site, the pattern of change over time of the noise or vibration (a pattern of noise or vibration that changes over time) (criterion pattern) may be analyzed in advance and recorded in the recording unit 22, and the on-site terminal 2 may be configured to determine whether or not the factor causing noise or vibration is present at the construction site by determining the degree of agreement between the noise or vibration pattern identified by the received first data and the criteria pattern.

[0116] In this case, a judgment criterion pattern may be generated and recorded for each piece of information indicating the construction process (such as information indicating the planned time period for each task) or for each type of equipment (such as heavy machinery) used in the construction, and the on-site terminal 2 may then refer to the construction information to determine the work currently being performed and the type of equipment currently being used at the construction site, and then identify the judgment criterion pattern corresponding to the identified work or type of equipment, and perform the above-mentioned processing based on the identified judgment criterion pattern.

[0117] The process for identifying the cause of the error may also be configured in a similar manner. The process for identifying the cause of the error on the server side may also be configured in a similar manner.

[0118] (Regarding regional evaluation (part 1)) Furthermore, the construction sites A to C in Figure 1 may be located in multiple relatively distant, different regions (for example, different cities, towns, villages, prefectures, or regions set in advance according to arbitrary rules), and the server device 3 may be configured to perform processing to manage the multiple regions based on the second data.

[0119] The recording unit 32 stores regional-related specific information (information indicating each region (information indicating the name, location, etc.), and information in which the sensor ID and terminal ID indicating the sensor device 1 and the on-site terminal 2 installed at the construction site in each region are mutually associated).

[0120] The server device 3 generates information indicating the characteristics of vibrations or noise in each region based on the second data, sensor ID, and terminal ID stored in the recording unit 32, and the region-related specific information, and outputs (e.g., displays) the generated information.

[0121] Specifically, although this is optional, for example, construction information may be referenced, and from the second data stored in the recording unit 32, noise or vibration patterns when no work is being performed at each construction site may be identified, and the identified patterns may be compiled by region (for example, by taking the average or adopting only a portion), thereby identifying noise or vibration patterns in each region when no work is being performed.

[0122] Furthermore, for example, by performing the same processing as above, noise or vibration patterns in each area when work is being performed may be identified, and these patterns may be applied to perform the above-mentioned processing.

[0123] (Regarding Regional Evaluation (Part 2)) Furthermore, the vibration-related characteristics explained in "Regional Evaluation (Part 1)" may be combined with earthquake-related items.

[0124] For example, after a disaster such as an earthquake occurs, the ground vibration characteristics of the area may be evaluated based on the first data accumulated in the on-site terminal 2. Also, for example, after a disaster such as an earthquake occurs, the ground propagation velocity may be evaluated based on the second data accumulated in the server device 3. Then, for example, information indicating the results of the identified ground vibration characteristics may be collected on the server device 3 side, and the information may be output (display output, etc.) as appropriate, so that the information can be reflected in the design of a building, etc.

[0125] Furthermore, for example, when a disaster such as an earthquake occurs, the server device 3 may be configured to determine based on the second data received that the magnitude of the vibration is at the level at which the disaster occurs, and then output an earthquake occurrence auxiliary alert to assist functions such as the so-called earthquake alert (alerts output by the Japan Meteorological Agency, etc.).

[0126] (User Terminal) In the above embodiment, the "other device" is the server device 3, but this is not limiting. For example, the above-mentioned user terminal may be used as the other device. In this case, the functions of the server device 3 described above may be provided in the user terminal, so that the user terminal performs the same processes as the server device 3 instead of the server device 3. Note that, for example, by providing only some of the functions of the server device 3 in the user terminal, the server device 3 and the user terminal may cooperate with each other to perform the above-mentioned processes.

[0127] (Regarding raw data, first data, and second data) Furthermore, in the above embodiment, as described in the "Explanation" column of Figure 6, it has been explained that the first data has less information than the raw data, and the second data has less information than the first data, but this is not limited to this, and the amount of information may be changed as desired.

[0128] For example, the raw data, the first data, and the second data may all have the same amount of information. Specifically, the sensor device 1 may transmit the same amount of data as the raw data as the first data to the field terminal 2, and the field terminal 2 may transmit the same amount of data as the first data as the server device 3. That is, for example, the raw data may be transmitted in the order of the sensor device 1, the field terminal 2, and the server device 3.

[0129] Furthermore, for example, the first data and the second data may have the same amount of information and may have less information than the raw data. Specifically, the first data and the second data may have the same information.

[0130] (Construction Sites) Although the management system 900 is described in FIG. 1 as being applied to multiple construction sites, the application target is arbitrary. For example, it may be configured to be applied to only one construction site. Furthermore, while FIG. 1 illustrates a case where construction sites A to C are located on different premises, this also applies when construction is being carried out at multiple locations on the same site. In other words, the sensor device 1 and the on-site terminal 2 may be installed at multiple locations within the same construction site.

[0131] 1 may be installed near the corresponding construction site. For example, they may be configured to be installed outside a temporary fence of a neighboring site or an adjacent factory on the same site.

[0132] (Interpretation of Terms) The raw data or the first data in Fig. 6 may be interpreted as corresponding to "first physico-chemical quantity information," and the second data may be interpreted as corresponding to "second physico-chemical quantity information." The construction information described above may be interpreted as corresponding to "construction-related information" (i.e., information related to construction at the target site). Furthermore, processes other than the above-mentioned specially mentioned processes may also be interpreted as falling under the category of "site management process" if they are processes for managing the target site.
