[0009] Hereinafter, the embodiments will be described in detail with reference to the accompanying drawings.

[0010] <Configuration of construction management system> FIG. 1 is a block diagram showing the configuration of a construction management system S according to this embodiment. As shown in FIG. 1, a construction management system S according to an embodiment of the present invention includes a management terminal 1, a detection unit 2, another terminal 3, and an external server 4.

[0011] The management terminal 1 is a communication terminal such as a smartphone, and the user is, for example, a construction site manager. A dedicated app (construction management application) is installed on the management terminal 1 in this embodiment, and the user can connect, configure, and acquire data from the detection unit 2 based on the operation of the dedicated app.

[0012] The other terminals 3 are communication terminals such as smartphones, and users thereof are, for example, workers at the construction site, construction companies, clients, etc. The other terminals 3 receive the management information transmitted by the management terminal 1 via the Internet 5.

[0013] The external server 4 provides information about the construction site. For example, the external server 4 in this embodiment provides weather forecast information (weather information) via the Internet 5. The management terminal 1 transmits the location information of the construction site to the external server 4 via the Internet 5, thereby obtaining weather forecast information for the area including the construction site from the external server 4. The weather forecast information includes, for example, precipitation, temperature, humidity, wind speed, etc.

[0014] The detection unit 2 is installed at the construction site or on land adjacent to the construction site, and detects (measures) the slope value of the installation location. The installation location of the detection unit 2 is, for example, a sheet pile or pile installed on the boundary between the construction site and the adjacent land, or a building adjacent to the construction site.

[0015] <Examples of using a construction management system> FIG. 2 is a diagram showing an example of use of the construction management system S. As shown in FIG. 2, the construction management system S is used, for example, at a construction site where a worker P2 operates a construction machine M to perform excavation work under the supervision of a site supervisor P1.

[0016] In this example, two detection units 2A and 2B capable of detecting inclination values ​​are used. Detection unit 2A is installed on a sheet pile 11 that separates the construction site from the adjacent land, and detection unit 2B is installed on a building 12 adjacent to the construction site. When in operation, detection units 2A and 2B detect inclination values ​​at predetermined measurement intervals and wirelessly transmit the detected inclination values ​​to the management terminal 1.

[0017] The management terminal 1 in this example of use is a smartphone carried by the site supervisor P1, and stores the tilt values ​​wirelessly transmitted from the detection units 2A and 2B as time-series data, linking them to the date and time of reception.

[0018] At a set time, the management terminal 1 sends time series data for the past few days (for example, two days) and events detected based on the time series data by email to the other terminal 3. Events detected based on the time series data suggest the impact of construction on the surrounding ground and surrounding buildings, such as the change in the inclination value of the sheet piles 11 following a different trend from the cyclical fluctuation of the previous day.

[0019] In this usage example, two other terminals 3A and 3B are used to receive emails sent by the management terminal 1 via the Internet 5. The other terminal 3A is a smartphone carried by a worker P2 at the construction site, and the other terminal 3B is a laptop PC carried by a client P3 who is located in a remote location away from the construction site.

[0020] The construction management system S used in this manner records the changes in slope values ​​at the construction site and its surrounding areas as time-series data, making it possible to evaluate the impact of construction on the surrounding ground and surrounding buildings based on the time-series data.

[0021] <Detection unit configuration> FIG. 3 is a block diagram showing the configuration of the detection unit 2. As shown in FIG. As shown in FIG. 3, the detection unit 2 includes a control unit 21, a battery 22, an angle measurement unit 23, a temperature measurement unit 24, a wireless communication unit 25, and a storage unit 26.

[0022] The control unit 21 is composed of an integrated arithmetic circuit such as a microcomputer equipped with an input / output interface, CPU, ROM, RAM, and RTC (Real Time Clock). By executing a predetermined program, the control unit 21 controls the operation and acquires information from the battery 22, angle measurement unit 23, temperature measurement unit 24, wireless communication unit 25, and memory unit 26. The RTC realizes a time synchronization function that recognizes the time and an alarm function that recognizes a specified time.

[0023] The battery 22 is, for example, a dry cell, and supplies power for operating the detection unit 2. The control unit 21 can measure the remaining battery power by using an AD conversion function.

[0024] The angle measurement unit 23 measures the tilt value of the location where the detection unit 2 is installed. For example, the angle measurement unit 23 is made up of an IMU (Inertial Measurement Unit), and measures three-axis acceleration and three-axis angular velocity, and outputs them to the control unit 21.

[0025] The temperature measurement unit 24 is made up of, for example, a temperature sensor, measures the temperature of the location where the detection unit 2 is installed, and outputs the temperature information to the control unit 21. This temperature information is used to correct the temperature error of the angle measurement unit 23.

[0026] The wireless communication unit 25 performs wireless communication with the management terminal 1 using a communication method such as BLE (Bluetooth Low Energy).

[0027] The storage unit 26 is configured using a rewritable nonvolatile memory such as an EEPROM. The information stored in the storage unit 26 includes information for each detection unit 2 set at the time of shipment from the factory, information set from the management terminal 1, information set by the operation of the detection unit 2, and measurement data acquired by measurement.

[0028] The information set from the management terminal 1 includes the measurement interval and installation direction. The measurement interval is a setting parameter that determines the interval at which the detection unit 2 measures the tilt value, and is set in units of minutes, for example. The installation direction is a setting parameter that specifies the installation direction of the detection unit 2, and a value that can identify whether it is horizontal or vertical is set.

[0029] <Functional configuration of the detection unit and management terminal> The detection unit 2 (control unit 21) includes a tilt value acquisition means, a measurement time information acquisition means, a tilt value storage means, and a tilt value transmission means as functional components realized by the cooperation of hardware and software.

[0030] The tilt value acquisition means acquires the tilt value measured by the angle measurement unit 23. For example, the tilt value acquisition means of this embodiment acquires the tilt value from the angle measurement unit 23 at a measurement interval set by the management terminal 1.

[0031] The measurement time information acquisition means acquires measurement time information (including the measurement date and measurement time) of the tilt value measured by the angle measurement unit 23.

[0032] The tilt value saving means saves the acquired tilt value, etc. in the memory unit 26 every time the tilt value acquiring means acquires a tilt value from the angle measuring unit 23. For example, the tilt value saving means of this embodiment stores the acquired tilt value in the memory unit 26 in association with the date and time of measurement.

[0033] The tilt value transmitting means transmits the tilt value acquired by the tilt value acquiring means from the angle measuring unit 23 or the tilt value stored in the memory unit 26 to the management terminal 1. For example, the tilt value transmitting means can transmit the tilt value stored in the memory unit 26 and the measurement date and time to the management terminal 1 in response to a data transmission request from the management terminal 1, or can transmit the tilt value and the measurement date and time to the management terminal 1 at the timing when the tilt value acquiring means acquires the tilt value from the angle measuring unit 23.

[0034] The management terminal 1 includes, as functional components realized by the cooperation of hardware and software, an inclination value storage means, a management information transmission means, a construction site information acquisition means, and an automatic measurement interval adjustment means.

[0035] The tilt value storage means receives and stores the tilt values ​​transmitted from the detection unit 2. For example, the tilt value storage means of this embodiment stores the tilt values ​​linked to measurement time information as time-series data.

[0036] The management information transmitting means transmits management information including the inclination values ​​received from the detection unit 2 and events detected based on the inclination values ​​to another terminal 3 via the Internet 5. For example, at a set time, the management information transmitting means of this embodiment transmits time series data for the past few days (for example, two days) and events detected based on the time series data by email to another terminal 3. Note that events detected based on the time series data suggest the impact of construction on the surrounding ground and surrounding buildings, such as, for example, the inclination value of a sheet pile changing in a manner different from the cyclical fluctuation of the previous day.

[0037] The construction site information acquisition means acquires information about the construction site from the external server 4 via the Internet 5. For example, the construction site information acquisition means of this embodiment acquires weather forecast information for the area including the construction site from the external server 4 by transmitting location information of the construction site to the external server 4 via the Internet 5.

[0038] The automatic measurement interval adjustment means automatically adjusts the interval at which the detection unit 2 measures the inclination value based on the weather forecast information acquired by the construction site information acquisition means. For example, the automatic measurement interval adjustment means of this embodiment determines whether the construction site area will be sunny, normally rainy, or stormy based on the acquired weather forecast information, and automatically adjusts the measurement interval according to the determination result. For example, when the precipitation rate in the weather forecast information is 0 to 1 mm / h or less, it is determined to be sunny, and the measurement interval is set to once per day. Furthermore, when the precipitation rate in the weather forecast information is 2 to 4 mm / h or less, it is determined to be normally rainy, and the measurement interval is set to once per hour. Furthermore, when the precipitation rate in the weather forecast information is 5 mm / h or more, it is determined to be stormy, and the measurement interval is set to once per minute.

[0039] It is desirable that the automatic measurement interval adjustment means automatically adjusts the measurement interval of the detection unit 2 based on measurement interval adjustment conditions preset by the user and weather forecast information. For example, the user presets a measurement interval for fine weather, a measurement interval for normal rainy weather, and a measurement interval for stormy weather, and then applies the measurement intervals set based on the weather forecast information.

[0040] According to this construction management system S, the manager of the construction site can evaluate the impact of construction on the surrounding ground and surrounding buildings by obtaining the tilt values ​​measured by the detection unit 2 via the management terminal 1. Furthermore, the measurement interval of the tilt values ​​measured by the detection unit 2 is automatically adjusted based on weather forecast information. Therefore, for example, during stormy weather when construction is likely to affect the surrounding ground and surrounding buildings, the measurement interval can be shortened to strengthen monitoring of the surrounding ground and surrounding buildings. Furthermore, during non-stormy weather (sunny weather or normal rainy weather), the measurement interval can be lengthened to reduce the number of measurements by the detection unit 2, thereby saving power. Furthermore, because the measurement interval is automatically adjusted based on weather forecast information, it not only reduces the burden on the user compared to manually adjusting the measurement interval, but also prevents users from forgetting to change the measurement interval or accidentally changing it.

[0041] The processing procedure of the management terminal 1 for realizing the above-described automatic measurement interval adjustment function will be described below with reference to FIG.

[0042] <Processing procedure for automatic measurement interval adjustment> FIG. 4 is a flowchart showing the processing steps for automatically adjusting the measurement interval in the management terminal 1. 4, the management terminal 1 acquires weather forecast information from the external server 4 (S1), and then determines whether the weather at the construction site will be sunny, usually rainy, or stormy based on the rainfall amount (rainfall amount per hour) in the acquired weather forecast information (S2). Next, the management terminal 1 determines whether the weather determined this time is the same as the previous time (S3), and if the result of this determination is YES, returns to the upper routine.

[0043] If the determination result in step S3 is NO, the management terminal 1 determines whether the currently determined weather is fine, normal rainy weather, or stormy weather (S4), and if it determines that it is fine weather, it selects the measurement interval for fine weather set by the user (S5). Also, if the management terminal 1 determines that it is normal rainy weather in step S4, it selects the measurement interval for normal rainy weather set by the user (S6), and if it determines that it is stormy weather, it selects the measurement interval for stormy weather set by the user (S7). Thereafter, the management terminal 1 sends a measurement interval change request to the detection unit 2 to change the measurement interval (S8).

[0044] Although the embodiments have been described in detail above, the present invention is not limited to the specific embodiments, and various modifications and changes are possible within the scope of the claims. In addition, it is also possible to combine all or a plurality of components of the above-described embodiments.

[0045] For example, in the above-described embodiment, the management terminal 1 includes the construction site information acquisition means and the automatic measurement interval adjustment means, but the detection unit 2 may include the construction site information acquisition means and the automatic measurement interval adjustment means.

[0046] Furthermore, the automatic measurement interval adjustment means in the above-described embodiment automatically adjusts the measurement interval of the detection unit 2 based on weather forecast information, but it may also automatically adjust the measurement interval of the detection unit 2 based on disaster information or construction schedules.

[0047] For example, disaster information includes information on earthquakes, typhoons, tsunamis, volcanic eruptions, etc., which may affect the ground and buildings around the construction site, so when a disaster occurs, the measurement interval of the detection unit 2 is shortened. This makes it easier to determine whether a change in the slope value is due to construction or a disaster.

[0048] Furthermore, the construction schedule identifies days when the construction site is likely to be affected by the ground and surrounding buildings (for example, the planned excavation date) and days when the impact is unlikely (for example, the planned survey date), so on days when the impact is likely to be felt, the measurement interval of the detection unit 2 is shortened. This makes it possible to more accurately evaluate the impact of construction work on the surrounding ground and surrounding buildings. [Explanation of symbols]
