Description

[Technical Field]

[0001] The present invention relates to a site information management system that manages the construction status at a site by a work machine that performs ground investigation, foundation work, and / or foundation work. [Background technology]

[0002] Traditionally, when constructing building structures or civil engineering structures, various types of ground investigations, ground work, and foundation construction are carried out. Ground investigations involve, for example, boring surveys to investigate the N-value, soil quality, and composition of the strata of the ground. Ground work involves construction such as ground improvement methods and pile foundations on the ground below the foundations and foundation slabs to support them. Foundation work involves construction to build the foundations that connect the ground to the structure.

[0003] Various construction methods are used for ground surveys, ground work, and foundation construction. For example, there are various pile foundation construction methods, such as the rotary press-in method, in which a steel pipe pile with a spiral blade at the tip of the steel pipe is rotary-pressed into the ground using a construction machine called a pile driver (see, for example, Patent Document 1).

[0004] When carrying out such ground investigations, foundation work, and foundation construction, it is necessary to record the construction status at each site and prepare a report. For this reason, a construction management system is known that records the construction status of work machines during construction at the site as construction performance data (see, for example, Patent Document 2).

[0005] According to the construction management system disclosed in Patent Document 2, construction performance data is recorded and displayed on a construction management device attached to a work machine on site, and is also transmitted to a data server via the Internet. The construction performance data sent to the data server can then be displayed on a viewing terminal in a site office or the like located away from the construction site. According to Patent Document 2, by displaying the construction performance data on the viewing terminal, the construction status can be grasped from a remote location.

[0007] However, in conventional construction management systems, there is a significant time lag between the time data is acquired from the work machine and the time it can be displayed on the viewing terminal. Due to this time lag, the construction status grasped by the viewing terminal is significantly delayed from the actual construction status at the construction site. As a result, viewers at the site office, etc., are unable to accurately grasp the current construction status at the site, such as the depth of the steel pipe piles, from the viewing terminal.

[0008] If the current construction status on site cannot be accurately grasped, it will be impossible to perform tasks such as instructing on-site workers on the timing of operating work machinery once the construction status reaches a target value, i.e., tasks that require collaboration between on-site workers and viewers in remote locations and require immediacy.

[0009] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a site information management system that can accurately grasp the construction status at a site by work machines performing ground surveys, ground work, and / or foundation work, even from a remote location, with virtually no time delay.

[0014] According to the above configuration, when measurement by the construction management device is started, The construction management device sequentially generates text-formatted transmission data relating to the operating status of the work machine based on sensor data acquired from the sensor continuously or at time intervals of one second or less. The construction management device sequentially generates construction status data for the site based on the ground information of the site previously acquired from the cloud server and the generated transmission data. The management display unit displays the construction status at the site while sequentially updating it based on the construction status data for the site. The gateway transmits the transmission data acquired from the construction management device to the cloud server at intervals of less than one second. The cloud server stores the transmission data acquired from the gateway, and sequentially generates construction status data for viewing based on the previously acquired ground information of the site and the transmission data acquired from the gateway, and transmits the construction status data for viewing to the viewing terminal at time intervals of one second or less in response to a request from the viewing terminal. The viewing terminal displays the construction status at the site while sequentially updating it based on the construction status data for viewing acquired from the cloud server. The construction status data for viewing generated by the cloud server and the on-site construction status data generated by the on-site construction management device are generated based on the same text-format transmission data, and by using text-format transmission data, it is possible to update the data at short intervals. Therefore, the construction status at the site displayed on the viewing terminal can be updated at intervals of less than one second by receiving the construction status data for viewing from the cloud server, and the construction status at the site by work machines performing ground surveys, ground work, and / or foundation work can be accurately grasped with virtually no time delay between the construction management device at the site and the viewing terminal at a remote location. This allows on-site workers and remote viewers to work together to carry out tasks that require immediacy.

[0015] In the first configuration, The construction management device An image of the management display unit displayed based on the on-site construction status data is transmitted to the cloud server via the gateway as construction status image data; The cloud server storing the construction status image data acquired from the gateway, and transmitting the construction status image data to the viewing terminal in response to a request from the viewing terminal; The viewing terminal is The construction status at the site may be displayed on the viewing display unit based on the construction status image data acquired from the cloud server (second configuration).

[0016] According to the above configuration, the viewing terminal displays the construction status at the site on the viewing display unit based on the construction status image data acquired from the cloud server. This allows the same image displayed on the construction management device to be displayed on the viewing terminal while reducing the burden on communication and viewing terminals, enabling on-site workers and viewers in remote locations to work together while viewing the same image.

[0017] In the first configuration, The construction management device The apparatus may have a storage unit for storing the transmission data and the on-site construction status data (third configuration).

[0018] According to the above configuration, the construction management device stores the generated transmission data in the storage unit. Therefore, even if the construction management device is unable to immediately access the cloud server, the transmission data stored in the memory unit can be sent to the cloud server via the gateway when the cloud server becomes accessible.

[0019] In any one of the first to third configurations, The cloud server Along with the ground information of the site, a list of piles to be constructed at the site is obtained in advance. Associating the on-site construction status data for each pile included in the pile list data with the pile list data; The viewing terminal is For a specific pile selected from a list of piles to be constructed at the site, it may be possible to display the current or past construction status at the site based on the corresponding on-site construction status data (fourth configuration).

[0020] According to the above configuration, the viewing terminal can display the current or past construction status at the site for a specific pile selected from a list of piles to be constructed at the site, based on the corresponding site construction status data. Therefore, the viewer can select the pile that he or she wishes to view from among the multiple piles being constructed at the site, and view the current or past construction status of that pile at the site.

[0021] [Embodiment] Hereinafter, a site information management system 100 according to an embodiment of the present invention will be described in detail with reference to the drawings.

[0022] The site information management system 100 according to this embodiment is a system that allows the construction status at a site to be accurately grasped from a remote location with virtually no time delay by recording, displaying, and sharing in real time the construction status at a site by work machines that perform ground work, foundation work, and / or soil investigations.

[0023] In this embodiment, as an example, a case will be described in which information relating to the construction of steel pipe piles by a construction machine 200 is recorded, displayed, and shared by the site information management system 100. The construction machine 200 is, for example, a pile driver such as a pole erection vehicle or a three-point pile driver. The description of this embodiment does not limit the ground work, foundation work, and soil investigation that are the subject of the present invention, nor does it limit the construction method, etc.

[0024] In the following drawings, the same or corresponding parts are denoted by the same reference numerals, and the description thereof will not be repeated. Note that, for ease of understanding, the configurations are shown in a simplified or schematic manner in the drawings referred to below, and some configurations are omitted.

[0025] [Overall configuration] FIG. 1 is a diagram showing a schematic configuration of a site information management system 100 according to an embodiment of the present invention. FIG. 2 is a block diagram showing a schematic configuration of the cloud server 10, construction management device 20, sensor 30, gateway 40, management terminal 50, and viewing terminal 60 that make up the site information management system 100. FIG. 3 is an example of a real-time image showing the construction status at the site, displayed on the construction management device 20. FIG. 4 is an example of a real-time image showing the construction status at the site, displayed on the viewing terminal 60. As shown in FIGS. 1 and 2, the site information management system 100 includes the cloud server 10, the construction management device 20, the sensor 30, the gateway 40, the management terminal 50, and the viewing terminal 60.

[0026] The site information management system 100 can share the status of pile construction at the site in real time by connecting the construction management device 20 and any terminals (management terminal 50, viewing terminal 60) to the cloud server 10 via the Internet. This allows the status of pile construction at the site by the work machine 200 to be accurately grasped even from a remote location with virtually no time delay.

[0027] The cloud server 10, construction management device 20, management terminal 50, and viewing terminal 60 each have communication capabilities via a communication network and are configured to be able to execute application software for recording, sharing, and displaying information related to pile construction.

[0028] The cloud server 10, construction management device 20, sensor 30, gateway 40, management terminal 50, and viewing terminal 60 that constitute the site information management system 100 will be described in detail below with reference to FIGS.

[0029] [Administrative terminal] The management terminal 50 is a terminal such as a PC installed in a head office or the like. The management terminal 50 generates and stores instructions for the work to be performed at the site in advance. The instructions for the work include list data for piles to be constructed at the site, columnar diagram data that is information about the ground at the site, and the like. Before constructing the piles at the site, the management terminal 50 transmits the instructions for the work to the cloud server 10 in advance and registers them.

[0030] [Cloud Server] Instructions regarding work content sent from the management terminal 50 to the cloud server 10 are stored in the cloud server 10. Furthermore, when the construction management device 20 is connected to the cloud server 10, the cloud server 10 sends instructions regarding work content, including list data of piles to be constructed at the site and columnar diagram data (especially N-values), to the construction management device 20. For example, AWS (Amazon Web Services, a cloud service provided by Amazon Inc.) can be used as the cloud server 10.

[0031] When measurement by construction management device 20 begins, cloud server 10 acquires data (transmission data) generated by construction management device 20. Furthermore, based on the data (transmission data) and the stored columnar diagram data and pile list data, cloud server 10 generates data (construction status data to be viewed) for viewing the construction status of the site on viewing terminal 60. The data (construction status data to be viewed) is transmitted to viewing terminal 60 in response to a request from viewing terminal 60.

[0032] [Sensor] The sensors 30 detect the operating status of the work machine 200 at the pile construction site as sensor data and input the sensor data to the construction management device 20. Examples of the sensors 30 include a GNSS (Global Navigation Satellite System) sensor 31, a depth sensor 32, a flow rate sensor 33, and a current sensor 34. Each sensor detects the operating status of the work machine 200 continuously or at time intervals of one second or less and inputs the sensor data to the construction management device 20.

[0033] [Construction management device] The construction management device 20 acquires sensor data from the sensor 30 and records and displays the construction status at the site by the work machine 200. The construction management device 20 has a control unit 21, a management display unit 22, a communication unit 23, and a memory unit 24. The control unit 21 includes a transmission data generation unit 25 and a site construction status data generation unit 26. The control unit 21 controls the operation of the management display unit 22, the communication unit 23, and the memory unit 24.

[0034] The transmission data generation unit 25 sequentially generates transmission data in text format relating to the operating status of the work machine 200, based on the sensor data acquired continuously or at time intervals of one second or less from the sensor 30. The sensor data includes data necessary for managing the piles, such as pile position information from the GNSS sensor 31, pile depth from the depth sensor 32, the amount of grout (cement milk) injected from the flow rate sensor 33, and current value from the hydraulic or current sensor 34. Note that the sensor data may also include, for example, hydraulic torque (if the pile driver is not an electric auger), press-in force (push-in force of the pile), or penetration amount (managed by the amount the steel pipe pile penetrates into the ground in one rotation), depending on the type of pile and construction method.

[0035] The site construction status data generating unit 26 sequentially generates site construction status data based on the ground information of the site acquired in advance from the cloud server 10 and the transmission data.

[0036] The storage unit 24 stores list data of piles to be constructed at the site and columnar diagram data, which are acquired in advance from the cloud server 10. The storage unit 24 also stores transmission data in text format generated by the transmission data generation unit 25 and on-site construction status data generated by the on-site construction status data generation unit 26.

[0037] The management display unit 22 displays the construction status at the site based on the construction status data for the site (see FIG. 3).

[0038] [gateway] The gateway 40 mediates communication between the cloud server 10 and the construction management device 20. Transmission data generated by the construction management device 20 is transmitted to the cloud server 10 via the gateway 40 at time intervals of one second or less.

[0039] [Viewing device] The viewing terminal 60 is used to view and check the construction status of piles in real time in a site office or the like that is distant from the work machine 200 at the construction site. The viewing terminal 60 is able to acquire data (construction status data for viewing) generated by the cloud server 10 and display the construction status at the site by the work machine 200. There are no particular restrictions on where the viewing terminal 60 is installed, and it may be near the work machine 200 at the construction site or in another remote location. The viewing terminal 60 may be a PC terminal, a tablet terminal, a mobile information terminal such as a smartphone, etc.

[0040] The viewing terminal 60 has a control unit 61, a viewing and display unit 62, a communication unit 63, and a storage unit 64. The control unit 61 controls the operation of each of the viewing and display unit 62, the communication unit 63, and the storage unit 64.

[0041] [Operation] Next, the operation of each part of the construction site information management system 100 when the construction machine 200 installs a steel pipe pile will be described.

[0042] The instructions for the work to be performed at the site, which are acquired from a management terminal 50 installed at a head office or the like, are stored in advance in the cloud server 10. The instructions for the work include a list of piles to be constructed at the site, columnar diagram data that is information about the ground at the site, and the like.

[0043] When the construction management device 20 is connected to the cloud server 10, instructions on the work content, including list data of piles to be constructed at the site and columnar diagram data (especially N values), which are pre-stored in the cloud server 10, are sent to the construction management device 20.

[0044] When measurement by the construction management device 20 begins, acquisition of sensor data from the sensor 30 begins. When pile construction by the work machine 200 begins, the sensor 30 detects the operating status of the work machine 200 as sensor data continuously or at time intervals of one second or less and inputs the data to the construction management device 20.

[0045] The transmission data generation unit 25 of the construction management device 20 sequentially generates text-format transmission data relating to the operating status of the work machine 200, based on sensor data acquired continuously or at time intervals of one second or less from the sensor 30. The transmission data includes instantaneous data and integral data of hydraulic pressure or current and voltage, which are data relating to the operating status of the work machine 200.

[0046] The generated transmission data in text format is sequentially stored in the storage unit 24 and is also transmitted to the cloud server 10 via the gateway 40 at time intervals of 1 second or less (for example, at 0.5 second intervals).

[0047] Furthermore, in the construction management device 20, the on-site construction status data generator 26 sequentially generates on-site construction status data based on the ground information of the site previously acquired from the cloud server 10 and the transmission data. The on-site construction status data is data that associates the columnar diagram data (particularly the N value) with the instantaneous data and integral data of hydraulic pressure or current contained in the transmission data.

[0048] The management display unit 22 of the construction management device 20 displays the construction status at the site based on the on-site construction status data. FIG. 3 is an example of a real-time image displayed on the construction management device 20 showing the construction status at the site. The real-time image displayed on the construction management device 20 displays a graph correlating the log data (particularly the N value) with the instantaneous and integrated data of hydraulic pressure or current contained in the transmission data. Numerical values ​​are also displayed for detailed items such as the auger rotation direction, excavation depth (m), excavation speed (m / min), instantaneous current (A), pile circumference fixing liquid (L), foot protection liquid (L), and instantaneous flow rate (L / min). This real-time image is updated at intervals of 1 second or less (for example, every 0.5 seconds).

[0049] The on-site construction status data also includes list data of piles being constructed at the site. Therefore, for example, an operator of the work machine 200 can display a list of piles on the management display unit 22 and select a pile being constructed from the list of piles to display the construction status of that pile in real time. In addition, by selecting a pile whose construction has been completed from the list of piles, the construction status of that pile can be checked later.

[0050] Meanwhile, the cloud server 10 stores the transmission data acquired from the gateway 40. It also sequentially generates construction status data for viewing based on the previously acquired ground information of the site and the transmission data. Like the on-site construction status data, this construction status data for viewing includes data for displaying a graph correlating the log data (particularly the N value) and the instantaneous data and integral data of hydraulic pressure or current included in the transmission data. Meanwhile, detailed items included in the on-site construction status data, such as the auger rotation direction, excavation depth (m), excavation speed (m / min), instantaneous current (A), pile perimeter fixing liquid (L), foot protection liquid (L), and instantaneous flow rate (L / min), may be omitted. The cloud server 10 also sequentially stores the generated construction status data for viewing.

[0051] In response to a request from a viewing terminal 60 installed in a site office or the like, the cloud server 10 transmits the construction status data for viewing to the viewing terminal 60 at time intervals of one second or less.

[0052] The viewing display unit 62 of the viewing terminal 60 displays the construction status at the site based on the construction status data for viewing acquired from the cloud server 10. FIG. 4 is an example of a real-time image displayed on the viewing terminal 60 showing the construction status at the site. The real-time image in FIG. 4 displays a graph correlating the log data (particularly the N value) with the instantaneous data and integral data of the hydraulic pressure or current contained in the transmission data. This real-time image is updated at time intervals of 1 second or less (for example, every 0.5 seconds), just like the construction management device 20.

[0053] The construction status data for viewing includes a list of piles being constructed at the site, just like the on-site construction status data. Therefore, a viewer who is located, for example, in a site office or a head office away from the site, can display the list of piles on the viewing display unit 62 and select a pile currently being constructed from the list of piles to view the construction status of that pile in real time. In addition, by selecting a pile whose construction has been completed from the list of piles, the construction status of that pile can be checked later.

[0054] On-site construction status data and viewing construction status data are Acquisition of sensor data (acquisition of operation information of the work machine 200 in real time) Integration with ground information (combined with ground data from the construction site) · Generation of construction status data (organization and analysis of data based on processing rules) The data is created according to a common processing procedure (algorithm), but the "real-time images" displayed based on each data differ depending on the user's purpose.

[0055] That is, the real-time image displayed on the on-site construction management device 20 based on the on-site construction status data is composed of detailed numerical data and graphs so that the operator of the work machine 200 can accurately grasp the pile construction status (Figure 3). In contrast, the real-time image displayed on the viewing terminal 60 based on the construction status data for viewing is configured to be a graph-centered image so that a manager located, for example, in a site office or head office away from the site, can easily understand the situation at the pile construction site (Figure 4).

[0056] [Effects of the embodiment] According to the on-site information management system 100 according to the present embodiment described above, when measurement by the construction management device 20 is started, The construction management device 20 sequentially generates transmission data in text format relating to the operating status of the work machine 200 based on the sensor data acquired from the sensor 30 continuously or at time intervals of one second or less. The construction management device 20 sequentially generates construction status data for the site based on the ground information of the site acquired in advance from the cloud server 10 and the generated transmission data. The management display unit 22 displays the construction status at the site while sequentially updating it based on the construction status data for the site. The gateway transmits the transmission data acquired from the construction management device 20 to the cloud server 10 at time intervals of one second or less. Cloud server 10 stores the transmission data acquired from the gateway, and sequentially generates construction status data for viewing based on the previously acquired ground information of the site and the transmission data acquired from the gateway. Then, in response to a request from viewing terminal 60, cloud server 10 transmits the construction status data for viewing to viewing terminal 60 at time intervals of one second or less. The viewing terminal 60 displays the construction status at the site while updating it sequentially based on the construction status data for viewing acquired from the cloud server 10. The construction status data for viewing generated by the cloud server 10 and the on-site construction status data generated by the on-site construction management device 20 are generated based on the same text-format transmission data, and by using text-format transmission data, it is possible to update the data at short time intervals. Therefore, the construction status at the site displayed on the viewing terminal 60 can be updated at intervals of less than one second by receiving construction status data for viewing from the cloud server 10, and the construction status at the site by the work machine 200 performing ground surveys, ground work, and / or foundation work can be accurately grasped between the construction management device 20 at the site and the viewing terminal 60 at a remote location with virtually no time delay. This allows on-site workers and remote viewers to work together to carry out tasks that require immediacy.

[0057] [Image display of construction management device on viewing terminal] As described above, the viewing terminal 60 displays the construction status at the site using real-time images based on the construction status data for viewing acquired from the cloud server 10, but in addition, it may be configured to display the same images as the real-time images displayed on the construction management device 20. An example of a means for displaying the images displayed on the construction management device 20 on the viewing terminal 60 will be described below.

[0058] The construction management device 20 acquires (captures) an image (see FIG. 3) displayed on the management display unit 22 based on the on-site construction status data as construction status image data. The data format is, for example, JPEG. The construction management device 20 transmits the construction status image data to the cloud server 10 via the gateway 40. The time interval for updating the construction status image data is arbitrary, but can be, for example, every 5 seconds.

[0059] Cloud server 10 stores the construction status image data acquired from gateway 40, and transmits the construction status image data to viewing terminal 60 in response to a request from viewing terminal 60. Viewing terminal 60 displays the construction status at the site on viewing display unit 62 based on the construction status image data acquired from cloud server 10.

[0060] In addition, since the construction status image data is data of the image displayed by the construction management device 20, if the construction management device 20 can display multiple types of images, the image selected by the construction management device 20 will be the construction status image data, but this is not limited to this.

[0061] As described above, the viewing terminal 60 can display the construction status at the site on the viewing display unit 62 based on the construction status image data acquired from the cloud server 10. This allows the same image displayed on the construction management device 20 to be displayed on the viewing terminal 60 while reducing the burden on communication and the viewing terminal 60, making it possible for on-site workers and viewers in remote locations to work together while viewing the same image.

[0062] [Variations] The embodiments disclosed herein are illustrative in all respects and are not intended to be limiting. The technical scope of the present invention is not interpreted solely by the above-described embodiments, but is defined by the claims. The technical scope of the present invention also includes all modifications within the meaning and scope of the claims.

[0063] After the piles are installed at the site, the construction status data for each pile (on-site construction status data or browsing construction status data) may be associated with the pile plan. In this case, the pile plan and the construction status data for each pile can be associated with GNSS data. [Industrial Applicability]

[0064] The present invention can be applied to a site information management system. [Explanation of symbols]
