Description

The present invention relates to a construction data management method and a program for managing construction data among related parties including a contractor, a building designer, a construction shop, and the like.

When building a building on soft geological ground, the foundation is reinforced by an appropriate construction method suitable for the ground. In the case of ground with a support layer at a deep position, the foundation will be reinforced by pile driving work. In this pile driving work, the pile is generally driven until the tip of the pile reaches the support layer, and the construction method is performed by supporting the tip.

In the construction of such foundation piles, it is confirmed that the tip of the pile has reached the support layer by acquiring the pile driving data at the time of construction. For example, the load current applied to the drive motor during excavation is measured, and it is determined that the tip of the pile reaches the support layer based on the change in the current value.

However, in 2015, when it was discovered that the condominiums in Yokohama were tilted, it became clear that the data for the pile driving work had been tampered with one after another. In addition, it was revealed that Toa Construction Corporation had falsified the construction data and made a false report to the Kanto Regional Development Bureau of the Ministry of Land, Infrastructure, Transport and Tourism in the ground improvement work at Haneda Airport. Such falsification of construction data has developed into a major social problem. On the other hand, in 2016, a large earthquake struck the Kumamoto region of Kyushu, and ensuring the safety and certainty of the foundation work of buildings has become a major social demand.

Therefore, it is necessary to promptly develop a system that ensures the safety and certainty of foundation work by ensuring the certainty and transparency that the ground work data acquired in the ground work such as pile driving work has not been tampered with. Is strongly desired.

◆ Explanation of basic configuration The management server 1, the field terminal 2, the approver terminal 3, and the process manager terminal 4 are connected to each other so as to be able to communicate with each other via the Internet 5.

The management server 1 is a server system including a communication interface, a central processing unit, a large-capacity data storage device, and the like. The management server 1 performs data communication with terminal devices (field terminal 2, approver terminal 3 and process manager terminal 4) accessed via the Internet 5 according to a protocol such as HTTP (HyperText Transfer Protocol).

The management server 1 has a website constructed in a predetermined language such as HTML, PHP, and XML, and responds to requests from each terminal device (field terminal 2, approver terminal 3, and process manager terminal 4). Then, a web page which is data including documents and images written in a digital document description language such as HTML or PHP is transmitted to each terminal device (field terminal 2, approver terminal 3, process manager terminal 4). ..

A unique network address (URL) is given to the management server 1. The user of each terminal device (site terminal 2, approver terminal 3 and process manager terminal 4) specifies the above URL on each terminal device (site terminal 2, approver terminal 3 and process manager terminal 4). By doing so, the management server 1 can be accessed.

Each terminal device (field terminal 2, approver terminal 3 and process manager terminal 4) browses the website with a browser for data including documents and images described in a digital document description language such as HTML. It has become possible. In addition, on the website, predetermined processing can be executed, such as inputting data such as documents and images and authentication information as necessary and transmitting them to the management server 1. Details of these operations will be described later.

The management server 1 is a server system provided with a communication interface, a large-capacity data storage device, and the like, and a central computing device reads a program recorded in an external storage device such as a hard disk device and executes processing according to the program.

As the field terminal 2, for example, a smartphone terminal, a tablet terminal, or a dedicated terminal can be used. The field terminal 2 is connected to the management server 1 via the Internet 5 to communicate with each other and execute processing to realize various functions as described later.

The approver terminal 3 and the process manager terminal 4 are connected to the management server 1 via the Internet 5 to communicate with each other and execute processing to realize various functions as described later.

◆ Explanation of basic functions Next, the basic functions of this embodiment will be described. As described above, the above basic function acquires construction data for each process at the site terminal 2 and transmits it to the management server 1. The management server 1 receives construction data related to each process. The received construction data is stored in the construction data storage unit 21. The process data for each process is stored in the process data storage unit 24 in advance. Then, the data disclosure means 19 combines the received construction data and the stored process data so that the data can be browsed as a website via the Internet.

◆ Characteristic functions The characteristic functions of this embodiment include a login function, a site unit authentication function, and a site code authentication function. It has other characteristic functions, but the details will be described later.

[Login function]
In the present embodiment, when the site terminal 2 is logged in to the management server 1 prior to the transmission of the construction data, the first login step and the second login step are executed.

In the first login step, the field terminal 2 is temporarily logged in to the management server 1. In the first login step, the site terminal 2 receives the terminal position of the site terminal 2 from a GPS satellite (not shown) and transmits it to the management server 1. In the management server 1, the terminal position received from the site terminal 2 is collated with the position of the construction area and authenticated. As a result, the field terminal 2 is temporarily logged in to the management server 1.

The terminal position is information on the position where the field terminal 2 exists when the first login step is being executed. Information on the latitude and longitude where the site terminal 2 is located is received from the GPS satellite to the site terminal 2.
The above construction area is an area where a series of construction works for acquiring construction data managed by this system are carried out. The position of the construction area is stored in the management server 1 in advance, and the terminal position received from the site terminal 2 is collated.
As a result of the collation, the management server 1 authenticates if the terminal position is within the range that can be authenticated, and puts the site terminal 2 in a temporary login state for the management server 1. If the terminal position is outside the range that can be authenticated, it will not be authenticated and login will be refused.

In the second login step, the field terminal 2 is officially logged in to the management server 1. In the second login step, the site terminal 2 transmits the construction area authentication data read from the authentication code installed in the construction area to the management server 1. The management server 1 authenticates the construction area authentication data received from the site terminal 2. As a result, the field terminal 2 is in the official login state for the management server 1.

The authentication code is a code installed one or more in the construction area. For example, the certification code can be installed at the entrance of the construction area. The data obtained by reading the certification code is the construction area certification data. The construction area authentication data corresponding to the construction area is stored in the management server 1 in advance, and the construction area authentication data received from the site terminal 2 is collated.
If the results of the collation match, the management server 1 authenticates and sets the site terminal 2 in the official login state for the management server 1. If the verification results do not match, authentication is not performed and login is refused.

GPS is also a location information confirmation, and location identification is duplicated, but in underground and high-rise buildings, the first login step using GPS is not performed, and only the second login step using the authentication code is executed. For outdoor works such as ground work, the first login step is also performed.

[Field unit authentication function]
In the site terminal 2 in the official login state, the step of authenticating the site unit for each site unit in the construction area is executed.

The site terminal 2 in the official login state transmits the site identification data read from the site code installed for each site in the construction area to the management server 1. The management server 1 authenticates the site identification data received from the site terminal 2.

The site unit is a unit of the site set at least one in the construction area. Usually, a plurality of site units are set in the construction area. It can be rephrased that the construction area is divided into a plurality of site units, and it can be rephrased that an aggregate of a plurality of site units is a construction area.
The site code is a code installed once for each site unit. For example, the site code can be installed within or near the site unit. The data obtained by reading the site code is the site identification data. The site identification data corresponding to each site unit is stored in the management server 1 in advance, and the site identification data received from the site terminal 2 is collated.

The management server 1 authenticates the site identification data. That is, if the verification can be performed, the site terminal 1 can transmit the construction data for each site to the management server. If the verification cannot be performed, the site terminal 1 cannot transmit the construction data for each site to the management server.

[Field code authentication function]
In the field terminal 2, the step of authenticating the field code is executed.
In the site terminal 2, the site code image obtained by capturing the range including the site code and its surroundings is transmitted to the management server 1. The management server 1 authenticates the site code image received from the site terminal 2.

The site code image is an image obtained by photographing a range including the site code and its surroundings. As the site code image, for example, the following can be used. As the site code, for example, a QR code (registered trademark) of about 5 cm square installed by the approver on the upper part of the wall surface of the indoor construction, about 1.8 m above the ground, is used. The site code image can be an image taken in a range of about 9 cm square including the QR code (registered trademark) and its surroundings.
The management server 1 stores the site code image corresponding to the site unit in advance, and receives the site code image taken by the site terminal 2. The management server 1 analyzes both the stored site code image and the received site code image, and compares the analyzed images. As a result of comparing the analysis images, if the agreement between the two is confirmed, the authentication is performed. As a result of comparing the analysis images, if the two do not match, the authentication is rejected. By authenticating the site code image received from the site terminal 2, it is ensured that the site code has not been moved from the installation location of the corresponding site unit.

In the first login step, the management server 1 receives the terminal position of the field terminal 2 received from the GPS satellite (not shown) in the field terminal 2. The management server 1 collates the terminal position received from the site terminal 2 with the position of the construction area stored in the login data storage unit 23.

For the terminal position, for example, latitude and longitude can be used. As the position of the construction area, the latitude and longitude of a predetermined place within or near the construction area can be used. Alternatively, it may be a fixed range based on the latitude and longitude of a predetermined location.

In the second login step, the management server 1 receives the construction area authentication data read from the authentication code installed in the construction area on the site terminal 2. The management server 1 collates the construction area authentication data received from the site terminal 2 with the construction area authentication data stored in the login data storage unit 23.

[Authentication data storage unit]
The authentication data storage unit 22 stores data necessary for executing the site unit authentication function and the site code authentication function described above. That is, the site identification data for each site read from the site code of each site used when executing the site unit authentication function is stored. In addition, the site code image used when executing the site code authentication function is stored.

In the site unit authentication function, the site code is read by the site terminal 2 to acquire site identification data, and the management server 1 receives it. The site code is a code installed once for each site unit. The site identification data corresponding to each site unit is stored in advance in the authentication data storage unit 22, and the site identification data received from the site terminal 2 is collated.

The site code authentication function authenticates the site code for movement or the like. In the site terminal 2, the site code image obtained by capturing the range including the site code and its surroundings is transmitted to the management server 1. In the management server 1, the site code image corresponding to the site unit is stored in advance in the authentication data storage unit 22.

Data is exchanged by these mutual communications, and various functions in the present embodiment are realized.

[Usage Authentication Department]
The usage authentication unit 14 realizes the login function described above. That is, the first login step and the second login step are executed.

In the first login step, the usage authentication unit 14 puts the field terminal 2 in a temporary login state for the management server 1. The usage authentication unit 14 collates the terminal position of the site terminal 2 received from the site terminal 2 with the position of the construction area stored in the login data storage unit 23. As a result of the above verification, if the terminal position is within the range that can be authenticated, the authentication is performed, and the on-site terminal 2 is put into the temporary login state for the management server 1. If the terminal position is outside the range that can be authenticated, it will not be authenticated and login will be refused.

In the second login step, the usage authentication unit 14 sets the field terminal 2 into a formal login state to the management server 1. The usage authentication unit 14 receives the construction area authentication data read from the authentication code by the site terminal 2 and collates it with the construction area authentication data stored in the login data storage unit 23. If the results of the verification match, authentication is performed, and the field terminal 2 is temporarily logged in to the management server 1. If the verification results do not match, authentication is not performed and login is refused.

[Analysis and Certification Department]
The analysis and authentication unit 15 realizes the above-mentioned site unit authentication function and site code authentication function.

In the site unit authentication function, the analysis and authentication unit 15 authenticates the site unit for each site unit in the construction area on the site terminal 2 in the official login state.
The site identification data read from the site code by the site terminal 2 is received, and the analysis / authentication unit 15 collates with the site identification data stored in the login data storage unit 23. If the verification can be performed, the site terminal 1 can transmit the construction data for each site to the management server. If the verification cannot be performed, the site terminal 1 cannot transmit the construction data for each site to the management server.

In the site code authentication function, the analysis / authentication unit 15 authenticates whether the site code has been moved. The site code image taken by the site terminal 2 is received. The analysis / authentication unit 15 performs image analysis on both the stored site code image and the received site code image, and compares the analyzed images. As a result of comparing the analysis images, if the agreement between the two is confirmed, the authentication is performed. As a result of comparing the analysis images, if the two do not match, the authentication is rejected.

[Time Management Department]
The time management unit 16 manages the time timing transmitted from the site terminal 2 with respect to the data received from the site terminal 2 when executing the login function, the site unit authentication function, and the site code authentication function. When the data is not transmitted within a predetermined time according to the content of the transmitted data, a predetermined time over process is performed. In the time-over process, for example, a message having a predetermined content is transmitted to the on-site terminal, the approver terminal 4, and the process manager terminal 5. Details will be described later.

◇ On-site terminal As the on-site terminal 2, a smartphone terminal or a tablet terminal can be used as described above. Further, a dedicated terminal can also be used for the field terminal 2.

The captured image data can be stored in the above-mentioned data storage unit 42.
As described above, the image capture by the camera mechanism 51 is captured by the control of the camera control unit 45 as the operation of the application program of the present invention. Further, as the operation of the application program of the present invention, an image can be taken by the camera mechanism 51 without being controlled by the camera control unit 45.

[Reading control unit]
The reading control unit 48 reads construction data from an external memory such as an SD card inserted in the reading mechanism 52. The construction data read here is transmitted to the management server 1 by the transmission / reception control unit 44 without being stored in the data storage unit 42.
The construction data read from the external memory is, for example, construction data measured or measured by a construction machine.

[GPS data receiver]
The GPS data receiving unit 58 receives the position information of the field terminal 2 from the GPS satellite. The position information of the field terminal 2 received from the GPS satellite is transmitted to the management server 1 by the transmission / reception control unit 44.

In the site code authentication function, the site unit authentication function accepts information for authenticating the site code image transmitted by the site terminal 2.

[Process Management Department]
The process management unit 47 manages the process for executing the login function, the site unit authentication function, and the site code authentication function described above based on the time measured by the internal clock 59. The time management unit 16 embeds a transmission time and an acquisition time in the data transmitted by the site terminal 2 when executing the login function, the site unit authentication function, and the site code authentication function, respectively. These transmission time and acquisition time are used for the time management process by the time management unit 16 of the management server 1 described above.

[Notification control unit]
The notification control unit 47 controls notification by the notification unit 56. The notification by the notification unit can be notified by, for example, a warning sound or a vibration. Alternatively, the warning information may be displayed on the display unit 55.

◇ Approver terminal The approver terminal 3 transmits authentication information such as an ID and password to the management server 1, logs in, and communicates with the management server 1 via the Internet 5. The approver terminal 3 first temporarily logs in to the system with an ID and password unique to the approver, and then officially logs in with the ID and password for each site.

The approver terminal 3 receives a message having a predetermined content transmitted by the management server 1 when the time over process is performed in the time management process by the time management unit 16 of the management server 1 described above.

◇ Process manager terminal Like the approver terminal 3, the process manager terminal 4 temporarily logs in with an ID and password unique to the process manager, and then officially logs in with an ID and password for each site. After that, mutual communication with the management server 1 is performed via the Internet 5.

The process manager terminal 4 receives a message having a predetermined content transmitted by the management server 1 when the time over process is performed in the time management process by the time management unit 16 of the management server 1 described above.

◆ Description of Operation The above system operates as follows to execute the construction data management program of the present invention and implement the construction data management method of the present invention.

◇ Operation of the field terminal (1) Starting the application program First, start the application program on the field terminal 2. The started application program is controlled and operated by the application control unit 21.

Next, a login operation for logging in the field terminal 2 to the management server 1 is executed. In the above login operation, the first login step is performed first, and then the second login step is performed.

(2) First Login Step By the first login step, the site terminal 2 is temporarily logged in to the management server 1.
First, the site terminal 2 transmits the ID and password of the site terminal 2 to the management server 1. In the management server 1, the usage authentication unit 14 inquires about the ID and password stored in the login data storage unit 23 to perform authentication.

Next, in the first login step, authentication is performed using GPS position information. The field terminal 2 receives the terminal position from the GPS satellite and transmits the received terminal position to the management server 1. The terminal position is the latitude and longitude where the field terminal 2 is located when the first login step is being executed.

The management server 1 authenticates the location information received by the usage authentication unit 14, and puts the site terminal 2 in a temporary login state for the management server 1.

The location of the construction area is stored in advance in the login data storage unit 23. The above construction area is an area where a series of construction works for acquiring construction data managed by this system are carried out. The usage authentication unit 14 collates the terminal position received from the site terminal 2 with the position of the construction area stored in the login data storage unit 23.

As a result of the above verification, if the terminal position is within the range that can be authenticated, the authentication is performed, and the on-site terminal 2 is put into the temporary login state for the management server 1. If the terminal position is outside the range that can be authenticated, it will not be authenticated and login will be refused.
In the field terminal 2, the authentication reception unit 46 receives the authentication information from the management server 1 and enters the official login state.

(3) Second Login Step In the second login step, an authentication code is installed at the entrance of a construction area or the like, and the authentication code is read by the site terminal 2 to formally log in. The authentication code is a code installed one or more in the construction area. The construction area is certified using the certification code installed on site. The second login step is performed within a predetermined time from the temporary login using the GPS described above.

First, the on-site terminal 2 reads the authentication code installed at the entrance of the construction area. The reading is performed by the camera mechanism 51, and the camera control unit 45 acquires the construction area authentication data embedded in the authentication code. The acquired construction area authentication data is transmitted to the management server 1.

In the management server 1, the usage authentication unit 14 authenticates the construction area authentication data received from the site terminal 2, and sets the site terminal 2 in the official login state for the management server 1. The login data storage unit 23 stores the construction area authentication data corresponding to the construction area in advance. The usage authentication unit 14 collates the construction area authentication data received from the site terminal 2 with the construction area authentication data stored in the login data storage unit 23. If the results of the collation match, the usage authentication unit 14 authenticates and puts the field terminal 2 in the official login state for the management server 1. If the verification results do not match, authentication is not performed and login is refused.
In the field terminal 2, the authentication reception unit 46 receives the authentication information from the management server 1 and enters the official login state.

By executing the second login step and officially logging in to the site terminal 2, the position of the site terminal 2 can be specified even in a place where the GPS radio wave does not reach. For example, in the case of wide area subway construction, a second login step and logout are performed at the entrance / exit of the construction area. If you use multiple authentication codes, you can handle large public works projects. For example, a first authentication code can be installed near station A at the subway construction entrance 15 m underground, and a second authentication code can be installed at station B 5 km away from it.

(4) Pre-construction processing This is a processing for preparing the above-mentioned site code authentication function.
First, the site code is read by the site terminal 2, and the acquired site identification data is transmitted to the management server 1. By using a Wi-fi repeater or the like, communication is possible even in a place where GPS radio waves do not reach, such as in an underground space. The management server 1 stores the received site identification data in the authentication data storage unit 22 in association with the corresponding site unit.

Next, the on-site terminal 2 photographs a range including the on-site code and its surroundings. The captured site code image is transmitted to the management server 1. The management server 1 stores the site code image received from the site terminal 2 in the authentication data storage unit 22 in association with the site identification data of the corresponding site unit. The site code image stored in the authentication data storage unit 22 is used as an original image for comparative analysis when the site code authentication function is executed.

(5) Reading and shooting the site code In the site terminal 2 in the official login state, the site unit is authenticated by using the site code installed for each site unit in the construction area.

<1> First, the site terminal 2 reads the site code installed for each site unit in the construction area. The reading is performed by the camera mechanism 51, and the camera control unit 45 acquires the site identification data embedded in the site code. The acquired site identification data is transmitted to the management server 1.
In the management server 1, the analysis authentication unit 15 searches for the site code image stored in the authentication data storage unit 22 as the corresponding original image for analysis using the received site identification data as an index.

<2> Next, in the site terminal 2, the site code image obtained by photographing the site code and the range including the surrounding area is transmitted to the management server 1. The camera control unit 45 controls the camera mechanism 51 to perform shooting.

<3> In the management server 1, both the site code image of the original image stored in the authentication data storage unit 22 and the received site code image are image-analyzed, and the analyzed images are compared. As a result of comparing the analysis images, if the agreement between the two is confirmed, the authentication is performed.
As a result of comparing the analysis images, if the two do not match, the authentication is rejected. In the first authentication refusal, the analysis authentication unit 15 again transmits a retry request for taking and transmitting the site code image to the site terminal 2. When the authentication is refused for the second time in the retry, the analysis authentication unit 15 transmits a notification to that effect to the approver terminal 3.
By authenticating the site code image received from the site terminal 2, it is ensured that the site code has not been moved from the installation location of the corresponding site unit.

<4> The site terminal 2 authenticates the site identification data, and receives the authentication information of the site code image from the management server 1. In the authentication reception unit 46, the site terminal 2 uses the construction data in the site unit. Can be sent to the management server 1.
The above construction data are actual measurement values, process images, and construction data.

On the site terminal 2 that can transmit construction data to the management server 1, one of the operations of "input of actual measurement value", "capture of process image", and "transmission of construction data" is selected.

(5-1) When "Input of actual measurement value" is selected The above actual measurement value is a value obtained by actually measuring dimensions and the like in order to confirm whether the construction site is actually completed as designed. The above-mentioned measured value is input in the field terminal 2 and transmitted to the management server 1.

When "input of actual measurement value" is selected on the field terminal 2, the "actual measurement value input screen" is displayed on the display unit 55. On the actual measurement value input screen, a process performed in the site unit identified by the site code and an input field of the actual measurement value to be input in the process are displayed. In addition, the "process confirmation completed" button is displayed on the actual measurement value input screen so as to be selectable.

Enter the measured measured value in the above measured value input field. When the input of the measured value is completed, the "process confirmation completed" button is pressed to complete the input of the measured value, and the input information is transmitted to the management server 1. The above-mentioned "process confirmation completed" button is a button for transmitting to the server that one process is completed and completed in the case of a process in which a plurality of actually measured value inputs are continuously performed. By pressing the "process confirmation completed" button, the input actual measurement value is transmitted to the management server 1, and the timer of the <tampering prevention process> described below is started.

<Falsification prevention processing>
In order to input the measured value, it takes a certain amount of time, such as while measuring at the site. Tampering is prevented by promptly performing the following operations after input is completed.

When the process confirmation completion button is pressed, the same site code that was first read within the specified time (10 seconds) is read on the site terminal 2, and the site code image is displayed within the next specified time (10 seconds). Take a picture and send it to the management server 1.
The management server 1 analyzes the received site code image, searches for the original image of the authentication data storage unit 22 using the site identification data as an index, compares them, and authenticates if they match.

As a result, it can be confirmed that the user was in that position before and after the input. That is, it can be confirmed that the input person has not been tampered with by leaving the site and inputting within a predetermined time (for example, within 3 minutes).

The procedure for reading the site code and shooting in (5) described above is as follows: <1> → <2> → <3> → <4> Actual measurement value input → Process confirmation completion button → <1> → <2> → <3> → <4>. If you are not at the installation position of the site code until just before the actual measurement value is input, you cannot operate <1> → <2> → <3> → <4>.

Therefore, after the actual measurement value input is selected, the input person leaves the site within a predetermined time (for example, 3 minutes), and no matter where the actual measurement value is input, the time is reached after the process confirmation completion button (immediately after the measurement value input is completed). By operating <1> → <2> → <3> → <4> within (for example, 10 seconds), it is confirmed that the site code is installed.

Conventionally, the input of the measured value for the design in the field work is recorded by writing it in a memo, etc., and is input to the computer device or the like in the later office work. For this reason, there are problems such as a mistake in writing in a memo and a mistake in inputting into a computer device.
In the present embodiment, the measured value is to be input to the on-site terminal at the site. Since the measured value requires an operation such as measuring with a tape measure, for example, it should be within 3 minutes, and once the measured value is input, there should be no other need, so for example, within 10 seconds <1> → <2> → <3> → < Each operation of 4> is requested.

Here, in the above-mentioned falsification prevention processing, both the site code is read / authenticated and the site code image is analyzed / authenticated. For the following reasons. This is because when the site code is moved, it cannot be determined only by reading and authenticating the site code. In addition, it is not possible to determine the impersonation when an elaborately disguised code is photographed only by analyzing and authenticating the site code image.

The same applies when the measured values are continuously input. The next input is made within a predetermined time (for example, within 1 minute) from the final input time, and when the final input is completed, the site code is read and certified within the specified time, and the site code image is taken for analysis and certification. ..

(5-2) When "Shooting of Process Image" is selected In the field terminal 2, the camera control unit 45 and the camera mechanism 51 take a process image within a predetermined time from the above selection.
First, the site code is read within a predetermined time, and the acquired site identification data is transmitted to the management server 1. Then, the site code image is taken and sent to the management server 1.
The management server 1 searches for the original image based on the received site identification data, analyzes the received site code image, and compares it. Authentication is performed by confirming that the two images match.

When the on-site terminal 2 receives the authentication information, the photographed process image is transmitted to the external management server 1. At this time, the captured process image is saved in the management server 1 and is not saved in the site terminal 2. This is to prevent the photo data from being tampered with by the on-site terminal 2.

When the above is completed, perform the above-mentioned <tampering prevention processing>, make sure that the photographer has not moved to another position within the specified time (for example, 1 minute) until shooting, and put the site code in another position. Make sure you haven't moved it.

In "shooting a process image", the shutter button of the camera mechanism 51 functions as a process confirmation completion button.

In the case of photography, you can do the following:
Within the time (1 minute) after selecting the shooting, after the operation of <1><2><3><4> at the installation position of the site code, after leaving the site and pressing the shutter at a different place, the time (1 minute) For example, return to 5 minutes) and perform the operations of <1>, <2>, <3>, and <4> at the same site code installation position.
Move the site code to a different location other than the installation position of the site code within the specified time (for example, 1 minute) after selecting shooting, and press the shutter after the operation of <1><2><3><4> to shoot. Then, within the time (for example, 5 minutes), the site code is returned to the original position and the operations of <1>, <2>, <3>, and <4> are performed.
In the present embodiment, the above operation cannot be performed within a predetermined time (for example, 10 seconds) after the shutter button is pressed, so that it can be confirmed that the user is at the installation position of the site code.

The same applies to the case of continuous shooting. The next shot is taken within a predetermined time (for example, within 1 minute) from the final shooting time, and when the final shooting is completed, the site code is read and certified within the specified time, and the site code image is shot for analysis and certification. ..

(5-3) When "Transmission of construction data" is selected The site terminal 2 transmits construction data within a predetermined time from the above selection.
First, the site code is read within a predetermined time, and the acquired site identification data is transmitted to the management server 1. Then, the site code image is taken and sent to the management server 1.
The management server 1 searches for the original image based on the received site identification data, analyzes the received site code image, and compares it. Authentication is performed by confirming that the two images match.

The construction data is data acquired by using a measuring device at the construction site, and the site terminal 2 reads it from an SD card or the like by the reading mechanism 52 and transmits it to the management server 1.

The management server 1 receives the construction data transmitted from the site terminal 2. The management server 1 receives the construction data only from the site terminal 2 which has been logged in and authenticated, and does not receive the construction data from other computer devices in principle. Only in the case of an emergency such as a failure of the on-site terminal 2, it can be received with the permission of the approver.

The construction data measured and measured by the construction machine is analyzed by the analysis and certification unit 15 of the management server 1.

When the construction data measured or measured by the construction machine is outside the recordable time set as the set time, the analysis and certification unit 15 of the management server 1 approves the above. A report is transmitted to the person terminal 3.

When the analysis / authentication unit 15 of the management server 1 transmits a report to the approver terminal 3, the analysis / authentication unit 15 also transmits the same report to the process manager terminal 4. This notification will allow the approver to obtain ex post facto permission.

As a result of analysis by the analysis / certification unit 15, if the recording time is out of the predetermined recordable time even though the transmission time of the construction data is within the transmittable time, the management server 1 sends the approver terminal 3 to the approver terminal 3. And send the report.
For example, if the recordable time is set from 9:00 to 17:00 and the transmittable time is set from 9:00 to 18:00, for example, 17:40 in the construction data transmitted at 17:50. This is the case where there is construction data recorded in. Since it is sent within the transmittable time, it can be transmitted from the site, but it cannot be denied that the data may have been corrected by bringing a small notebook computer or the like to the site, for example. In such a case, it is necessary to have the approver explain why the recording was made after the work was completed (the time when the site supervisor or the manager would be absent).

Dedicated software for all construction machines is installed on the management server 1, and data of each model can be processed. The management server 1 makes the construction data read-only so that it cannot be overwritten. Loginable persons (designers, site supervisors, etc.) other than approvers and approvers can only view on the logged-in computer device, smartphone terminal, or tablet terminal. Even if the same software is installed on the computer device, it cannot be tampered with.

The final recording time of the above-mentioned construction data is determined by the analysis of the analysis / authentication unit 15 of the management server 1. That is, the latest recording time is determined among the recording times of the plurality of transmitted construction data. Then, when the transmission time exceeds a certain elapsed allowable time from the final recording time, the analysis authentication unit 15 of the management server 1 transmits a report to the approver terminal 3.

For example, when the allowable elapsed time such as 60 minutes, 90 minutes, 120 minutes, or 150 minutes is set from the last recording time and the transmission time exceeds the allowable elapsed time, why is the transmission within the allowable time from the end of recording? This is because it is necessary to explain to the approver whether or not the process could be completed. By using such processing as a barrier against data tampering, data tampering is prevented.

In the processes (5-1), (5-2), and (5-3) described above, the authentication of the field code image includes the following patterns A and B.
Pattern A: In any of the case of inputting the measured value, taking the process image, and transmitting the construction data, if the site code image to be transmitted after that is analyzed and does not match, the management server performs processing such as the above-mentioned retry request. Received measured values, transmitted data and images are deleted.
Pattern B: The site code image immediately before the work and the site code image immediately after the work are analyzed and compared instead of the site code image registered in advance. In the presence of the site manager, if the above-mentioned retry request is OK, it will be authenticated. In other words, it has not been moved. At the site, the installed site code may be soiled or scratched due to sudden circumstances, so the distance-view images immediately before and after are used.

Associate the process image with the process data.
The captured process image is associated with the site identification data obtained by reading the site code immediately before and after. As a result, the site ID, the site code installation position information, and the like can be associated with the process image.

The site unit is moved and each process of (5) described above is repeated.

(6) Logout processing Logout processing using the authentication code is performed.
The site terminal 2 reads the authentication code and transmits the construction area authentication data to the management server 1.
The management server 1 inquires the process data storage unit 24 about the process scheduled for the work day in the construction area corresponding to the received construction area authentication data (site ID).
If the scheduled process does not remain, the logout permission is transmitted to the site terminal 2. The field terminal 2 receives the logout permission and enters the logout state.
If the scheduled process remains, a notification to that effect is transmitted to the site terminal 2. In this way, when all the construction data of the scheduled process has not been transmitted, a warning is sent to the site terminal 2.

<End irregular processing>
In the above logout process, if irregularity occurs at the end, the management server 1 executes the following process.

A: Leaving the site without reading the authentication code First, it is conceivable that the site terminal 2 will leave the site without reading the authentication code before all the construction data transmission of the scheduled process has been completed. Be done. For example, it landed on the ground during subway construction. In such an irregular situation, the management server 1 detects the inside and outside of the area with GPS, warns the user, and logs out.

explain in detail.
When the application program is started on the site terminal 2, the GPS switch of the site terminal 2 is forcibly turned on by the application program.
When the field terminal 2 reaches a position where it can be positioned by GPS satellites, the position information is transmitted to the management server 1.
The usage authentication unit 14 of the management server 1 has determined that the GPS position information is transmitted from the on-site terminal 2 that has not logged out, and that the process remains.
Then, it checks whether it is inside or outside the GPS area (for example, a radius of 20 m).

In the above verification, the site terminal 2 receives the longitude / latitude information from the GPS satellite, and the management server 1 receives the longitude / latitude information received by the site terminal 2 from the GPS satellite. That is, the site terminal 2 communicates with the management server 1, the management server 1 detects whether or not the site terminal 2 is in the GPS area, and the position information of the site terminal 2 is examined and grasped.

As a result of the above check, if it is outside the area, an alarm will be issued. In the above alarm, the site terminal 2 is instructed to perform any of a process change operation, a process deletion operation, and a process end operation. Even outside the area, if you change or delete the process, you will be logged out. At this time, the management server 1 notifies the approver terminal 3 to that effect. By performing such processing, the person in charge of the field terminal 2 will be asked the reason by the approver, so that the person in charge will follow the process.

As a result of the above inspection, if it is within the area, a display calling attention will be displayed. The above display displays on the screen that the process remains and GPS is detected. As a result, the process is surely left in the state.

For example, in the case of subway construction, there is a case where the process work is performed by returning to the subway site after having a meeting at the site office on the ground with the process remaining without logging out underground. If it is within the area, only a display that calls attention is given. Change whether it is "warning" or "display" depending on the inside and outside of the area.

B: When the other irregular field terminal 2 terminates the application program, GPS detects the inside and outside of the area, warns the user, and logs out.

explain in detail.
<A> The application program was terminated with the process remaining.
In this case, the management server 1 displays a warning to the site terminal 2 that "the process cannot be terminated because the process remains", and the application program is not terminated.
<B> The power was turned off.
In this case, the management server 1 displays a warning to the site terminal 2 that "the process cannot be terminated because the process remains", and the application program is not terminated.
<C> Battery is dead (forced OFF depending on the model)
In this case, the warning processing as described in <a> and <b> above cannot be performed. The power is restored, and after the application is started and the login request is processed, the same process as A above is executed.

Here, when the power supply of the site terminal 2 is restored and the application program is restarted with the process of unprocessed construction data transmission remaining, the site terminal 2 is in the initial login standby state.

If the on-site terminal 2 restarted by this power restoration is within the GPS area of the construction area where the process of unprocessed construction data transmission remains and the unprocessed process remains, the management server 1 is the first. Temporarily log in at the login step of. Then, in the second login step, the construction area authentication data is read and the official login is performed. In this way, the processing can be continued without any problem. It is assumed that the battery is usually dead.

In addition, when the on-site terminal 2 restarted by power restoration has a process for which construction data transmission has not been processed remains, the management server 1 refuses to log in to all construction areas other than the construction area where the process remains. do. By changing or deleting the process, the user is logged out and the approver terminal 3 is notified by e-mail or the like. By doing so, the approver will ask the reason, and there is a risk of losing credibility, so that the person in charge of the field terminal 2 will follow the process.

In addition, when the site terminal 2 in which the process for which the construction data transmission has not been processed remains is outside the GPS area of the site where the unprocessed process remains, or when it is outside the scheduled process date, the approver Send a notification to the terminal 3.

If the site terminal 2 at that time is outside the GPS area of the construction area where the unprocessed process remains, login to all construction areas other than the construction area where the process remains is refused. By changing or deleting the process, the user is logged out and the approver terminal 3 is notified by e-mail or the like.

If the site terminal 2 at that time is other than the scheduled process date in the GPS area of the construction area where the unprocessed process remains, the following process is performed.

When changing the process date, change the process date, temporarily log in in the first login step, read the authentication code in the second login step, and become a formal login. The change in the process date is notified from the management server 1 to the approver terminal 3. By doing so, the approver will ask the reason, and there is a risk of losing credibility, so that the person in charge of the field terminal 2 will follow the process.

If the process date is not changed, delete the process and log out without the process. The process deletion is notified from the management server 1 to the approver terminal 3. By doing so, the approver will ask the reason, and there is a risk of losing credibility, so that the person in charge of the field terminal 2 will follow the process.

◇ Operation of management server The management server 1 performs the following processing while communicating with the field terminal 2.
(1) Authentication process for [temporary] login of field terminal (above)
(2) Authentication process for [official] login of field terminal (above)
(3) Pre-construction processing using on-site terminals (described above)
(4) Reading and photographing the site code with the site terminal (described above)
(5) Logout process of field terminal (described above)

The following processes are performed according to the above (1) to (5) described in the above-mentioned operation of the field terminal 2.

◎ If the actual measurement value is not input or the process image is not taken within the specified time, a warning is sent from the management server 1 to the site terminal 2 by e-mail at a predetermined timing (for example, 10 minutes before).

◎ When the input of the actual measurement value of the scheduled process, the shooting of the process image, and the transmission of the construction data are completed, the actual measurement value of the scheduled process is sent from the management server 1 to the approver terminal 3 and the process manager terminal 4 by e-mail or the like. Notify that the input, the shooting of the process image, and the transmission of the construction data are completed.
Even if the actual measurement value is not input or the shooting is not performed within the designated time, the management server 1 notifies the approver terminal 3 and the process manager terminal 4 by e-mail or the like.

Here, the process manager is mainly a subcontractor who is engaged in process coordination with the main contractor and is mainly a manager of the company to which the on-site terminal user belongs.
This system requires notification to the approver for significant processes. The approver is mainly an authority (orderer side, design supervision company, etc.).
From the viewpoint of human error prevention, it is necessary to notify the contractor (terminal subcontractor side, ground investigation company, etc.) in order to protect the process in a small sense. Therefore, we decided to notify the process manager as well.

In addition, this system is for the approver side (the owner / design supervisor on the ordering side) from the viewpoint of falsification prevention. From the viewpoint of human error prevention, it is also a system for contractors (subcontracted geotechnical investigation companies, etc.) (improvement of operational efficiency).

◎ A warning is issued if a logout operation is performed using the authentication code while the specified process remains. In this case, the management server 1 displays a warning to the site terminal 2 that "the process cannot be terminated because the process remains", and the application program is not terminated.

◎ If the site terminal 2 leaves the site without logging out with the authentication code while the specified process remains, GPS detects it and issues a warning. That is, the same process as A of the above-mentioned end irregular process is performed.

◎ Construction data from machines, etc. is received and analyzed only from the site terminal 2. The necessary software (software for construction machines) is installed in advance on the management server 1. Read the recording time of the received construction data. If it is outside the set time, a notification is sent to the approver terminal 3 so that the ex post facto permission can be obtained. However, images taken with a commercially available digital camera are not received, and only images taken with a dedicated application program are received.

◎ Performs overtime transmission standby processing. When the actual measurement value, the photographed image, and the construction data are transmitted from the site terminal 2 after hours, the site terminal 2 is displayed as "standby without moving" so that the user cannot log out. In addition, it warns that the on-site terminal 2 will go out of the area, and waits for consent from the approver terminal 3.

The management server 1 stores the construction data (actual measurement value, process image, construction data) received from the site terminal 2 in the construction data storage unit 21 by the above-mentioned (4) reading of the site code by the site terminal and the processing of shooting. do. Further, the data disclosure means 19 makes it possible to browse the construction data (actual measurement value, process image, construction data) stored in the construction data storage unit 21 via the Internet 5.

In addition, the data disclosure means 19 performs a process of making the process image viewable together with the process data. The process data is design data, allowable value data, actual measurement data, and the like. The process data reflects the input actual measurement value and the like and is stored in the construction data storage unit 21 for viewing.

FIG. 3 is a diagram showing a display example in which the process image and the process data can be viewed by the data disclosure means 19. This is a display example by various terminal devices such as a computer device and a tablet terminal connected to the Internet 5.
The process information (character information such as construction name and construction location and graphic information (bean diagram)) displayed in the process display setting is displayed together with the process image.

Display example 1 is a standard type. A table of process information is displayed side by side on the process image associated with the process.
Display example 2 is a telop type. The characters of the process information are superimposed on the displayed process image and displayed.

The viewer can select the display position, display size, display color, etc. set by the approver. For example, the following can be specified.
Display method: Telop type Display position: Lower left Display size: 1/4 of the photo
Display color: Black Character frame: None By making it possible to select such a display method, it is possible to make the browsing display easier to see according to the needs.

Both the standard type and the telop type are displayed to the last, and are not written and saved in the process image or process data.

Images and the like to be viewed on the management server 1 can also be viewed on the site terminal 2. Therefore, the image can be stored in the internal memory of the field terminal 2. However, since the image file cannot be transmitted from the internal memory of the field terminal 2 to the management server 1, it does not cause falsification.

When the process image is displayed on various terminal devices by the data disclosure means 19, the process image can be displayed in an order according to the importance of the process image.

The above importance is set for each process image.
Specifically, the process chart (for example, the setting of process A) is uploaded to the management server 1 in advance. The uploaded process chart is stored in the process data storage unit 24. The importance is set in advance for each scheduled process image. The captured process image is received from the site terminal 2. Immediately analyze the image and acquire the shooting time and site identification data. The process A set by the recorded site identification data (construction ID and site code position information) is searched and stored so as to be displayed according to the importance according to the preset process image.

For example, if the importance is "2-ABC", "2" is the importance for submission to the government office. "ABC" is displayed when viewed by the "A" owner, the "B" construction company, and the "C" specialized company. In other words, you can log in with a unique ID and browse, and you can see whether it is the owner or the construction company, so the display is changed depending on the browsing ID. This makes it easier to browse. For example, if the importance is "ALL", all viewers can view it. The importance is an item that requires the approval of the approver.

◆ Modification example 1
In the first embodiment, it is possible not to analyze and authenticate the site code image.
For example, in the case of ground construction, the position is specified by GPS in the first login step, and the measured value, process image, and construction data can be transmitted by authenticating the authentication code in the second login step. In this modification 1, it is possible to deal with a case where authentication by analysis of a site code image is difficult due to weather or an external force in outdoor work.

Also in this modification 1, the second login using the authentication code is performed. The construction area certification data read from the certification code is used in association with the process image.

◆ Modification example 2
In the second modification, in the first embodiment, the single steps are combined and the steps are set and handled.
For example, (a) station A (measured value input), (b) station B (measured value input & process image shooting), and (c) construction data transmission are set as a process set, and (a) and (b) are If it is not completed, (c) will not be possible. The process is completed when (c) is completed.
By doing so, if it is within the set time, the process is set regardless of the construction order, and the work error of repeating the simple process is prevented.

For example, if there are about 20 simple processes, the number of notifications will increase. Of the simple processes from No. 1 to No. 20, No. 18, No. 20, No. 6, and No. 2 are indispensable, and if the final process is No. 4, from 9:00 to 17:00 within the set time, No. 18 , 20th, 6th, 2nd, and 4th are completed, you will be notified. The management server 1 and the site terminal 2 communicate with each other each time a simple process is completed, and the site terminal 2 displays how many essential processes remain.
Make it possible to individually set whether to use the field code or not. For example, it corresponds to construction work in which the same work is repeated at different sites, such as ground surveys.

The model premised on the second modification is as follows.
For example, in the case of a residential ground survey, it is possible to conduct a residential ground survey on the same day at only three locations. Although the location is different in a large condominium, if the survey contents are the same because they are close to each other, the simple process is to take pictures of the north, south, west, and east sides of the planned construction site (each simple process 1). No., No. 2, No. 3, No. 4). Although these are essential photographs, it is not necessary to notify the approver each time a photograph is taken.

What is important is the ground construction data acquired by the survey machine. Survey point No. 1, No. 2. No. 3, No. 4 (simple processes No. 5, No. 6, No. 7, and No. 8, respectively).

As the input of the measured value, "there is water on the site" and "there is no water on the site" is set as the simple process No. 9, and as the transmission of the construction data (No. 1 to No. 4) is set as the simple process No. 10.

As long as it is within the working time (9:00 to 17:00), the process work order does not matter. However, the final work process is set as simple process No. 10 (construction data is transmitted).

The process setting of the modification 2 will be described.
The simple process No. 10 should not be completed unless the simple process Nos. 1 to 9 are completed at the site.
When the simple process No. 10 is completed, the work process is completed, and the management server 1 notifies the approver terminal 3 and the process manager terminal 4 by e-mail or the like that the simple process No. 10 is completed.
By doing so, if the completion of the work process is notified, the simple steps 1 to 9 are also completed at the same time. The process manager can check the contents of the process execution and prevent work mistakes of field workers in advance in order to improve customer satisfaction.

In the second modification, from the viewpoint of preventing work mistakes, the site terminal 2 and the management server 1 communicate with each other every time the simple processes 1 to 9 are completed, and which simple process remains in the site terminal 2 is determined. Display it to prevent forgetting to work.
By eliminating these small mistakes, process managers (such as subcontracted geotechnical investigation companies) can prevent invisible losses due to mistakes and increase customer satisfaction.
In this way, the process setting function prevents forgetting the work process.

In the second modification, the notification at the completion of each simple process and the use of the site code can be set individually. That is, in the process setting, the next operation can be individually set for each completion of the simple process.
・ Notify either the approver terminal 3 or the process manager terminal 4 ・ Notify both the approver terminal 3 and the process manager terminal 4 ・ Request / do not read the site code

For example, when the simple process 1 (simple photography) is completed, if "notify the completion by e-mail only to the process manager", the worker does not operate anything and the process manager is the worker. However, the process manager, who knows that the work has started at the site and is familiar with the work contents, says that it takes about 1.5 hours to complete the work. Since there is an absolute worker at the site until the simple process 10 is completed after confirmation, the retake of the out-of-focus photograph may be instructed by a call or an email to the site terminal.

For example, when the construction data acquisition position of the simple process 5 is important, the approver installs the site code on the wooden stake or the chopstick in advance at the construction position of the site, and within the time (for example, 10 seconds) after shooting, the site. You can only read the code and instruct to send it.
Although it cannot be confirmed by the site code image outdoors, reading the site code within a predetermined time after shooting in the GPS area definitely means that the position was shot.

In this way, depending on the location of the site and the work content, it is possible to finely set for each simple process whether to notify anyone or not to use the site code.

In the second modification, a temporary login by GPS and a formal login by an authentication code are required. All the operations of steps 1 to 10 are OK if they are within the GPS area and within the time, and OUT if they are outside the GPS area and outside the time.

In the second modification, the construction area certification data is associated with the process image. Outdoor work such as ground surveys can be done even in heavy rain. Mandatory reading of the site code and acquisition of the site code image may cause deterioration of accuracy and unsafe behavior due to rainfall. Using GPS, the authentication code only needs to be read once for associating with the process image.

For example, as in the above example, if the work content of the ground survey is the same and three houses are constructed on the same site (vacant lot for sale), if three houses are photographed, it will be almost the same. All the steps are similar. If this happens, careless mistakes will occur, such as making a mistake, forgetting something, and taking a picture of blurring (it is difficult to check with a small digital camera LCD in rainy weather). Because I forgot to take one photo, it took time and effort to take it again. In other words, the management side spent time and money solving careless mistakes of workers. In the second modification, this can be prevented and such waste is eliminated.

Previously, nothing was known until the worker returned to the company, but in the modified example 2, it is possible to check the construction data and the process image when the worker is at the site. You can also give additional instructions and retake instructions on the spot. In this way, it leads to improvement in accuracy. It solves the problems of contractors in many fields such as ground survey / ground construction, house survey, and periodic maintenance and inspection of machinery and equipment.

Second Embodiment FIG. 4 is a system configuration diagram illustrating a second embodiment of the present invention.
The second embodiment is added with a function of additionally creating and setting a process. The management server 1 has a process creation unit 43 that performs the additional function. As a result, in the operation of the application program of the field terminal 2, a process is added and transmitted to the management server 1, and the management server 1 accepts and sets the process. When the process is not set in advance, it is possible to perform shooting or input of the measured value which is not set in advance.

With the on-site terminal 2 officially logged in, display the "on-site process creation" menu, and select taking a process image or inputting an actual measurement value displayed there.

When shooting is selected, after the process image is taken, the station and input items, if any, are input, and the photographic importance is input and transmitted.
If you select the actual measurement value input, enter the actual measurement value.

In this case, the construction area certification data read from the certification code is associated with the image file of the process image and the process created at the site.
Generally, in order to easily organize images later with a photo organizing software or the like, searchable data is recorded in an image file. Otherwise, the image file will only tell you the shooting time. In other words, it is the same as the image taken by a conventional digital camera.

In this system, in order to associate the captured process image with the corresponding process data, the construction area authentication data read from the authentication code is associated with the image file.

For example, when an unexpected accident occurs at the site and it is taken as a process image, select the option "Accident process" in the "Create site process" menu of the site terminal 2 and create a new site process. do.
Take a process image in the newly created on-site process "accident process".
Then, for example, the following information is input / set and transmitted to the management server 1.
-Measured value input: "Accident near the stairs on the 2nd floor! No injuries ”
-Photo importance: Initial value "ALL", no change-Notification: Initial value "Approver", no change Here, "Notification" means from management server 1 to approver terminal 3 and process manager terminal. It is a notification by e-mail or the like sent to 4. For example, in the case of an accident process, when a process image is taken in the accident process and received by the management server 1, the approver terminal 3 and the process manager terminal 4 are notified by e-mail.

By doing so, it is possible to take a picture other than the process expected in advance and input the measured value, which is necessary according to the individual site situation such as an accident or consultation.

In the first embodiment described above, in (5) reading and photographing the site code by the site terminal, one of "actual measurement value input", "shooting of process image", and "construction data transmission" is selected.
Actions at the site are expected in advance, and the results can be recorded on the website in real time via the Internet by inputting actual measurement values and taking process images to record the finished product for the process. I am trying to do it.

In this second embodiment, both "taking a process image" and "inputting an actually measured value" are performed in a series of flows.
In the field process (accident process, etc.), in order to convey unexpected things on the website in real time via the Internet, in order to convey information that cannot be transmitted only by photographs, taking process images (accident photographs) and inputting measured values This is because it is necessary to perform both (explanation of the site situation) in a series of steps.

Here, in the second embodiment, when the site code is not used, the construction area authentication data (site ID, etc.) read from the authentication code read at the time of login is recorded in the internal memory of the site terminal 2.

When the accident process is selected by the menu operation, the accident shooting becomes possible, and when the shutter is pressed, the accident process is transmitted to the external server and transmitted to the management server 1 within a predetermined time.
When the management server 1 receives "selection of accident process by menu operation" from the site terminal 2, the accident process is created by the reception time name, and the construction area authentication data read from the authentication code is associated with the accident process image. Write the construction area certification data read from the certification code in the accident process image and save it in an accident folder separate from the process.

When "select an accident process by menu operation", the accident process is created by the reception time name on the management server 1 when the accident process is selected. If you select "Enter accident measurement value in the menu", you can enter the accident measurement value. For example, "Crane tipping over! Zero injuries! ] Is possible for input.

In "Select accident process by menu operation", the photo importance can be set to ALL (viewable by all) in advance. The display of the accident process can also be set. Therefore, the accident process image is stored in the management server 1 in a state where it can be browsed on the Internet. In this browsing display, the accident process image can be searched by the construction area authentication data, and the accident process actual measurement value associated with the search can be displayed. The on-site process is a process that is not set in advance, such as an accident process or a consultation process. Set the expected events for each site.

The process image data taken by the application program is transmitted to the external management server 1 and is not stored in the site terminal 2. This is to prevent the photo data from being tampered with by the on-site terminal 2. Further, the reason for transmitting the process image data to the external management server 1 is that the image that failed to be photographed can be deleted within a certain period of time (for example, 10 seconds) after the shutter is pressed.

At this time, when logging in, the construction area authentication data read from the authentication code is used. Therefore, the measured value input items can be viewed in real time on the management server 1 according to the importance of the photograph, and the approver terminal 3 is notified.

As described in the first embodiment, it is an important purpose to accurately prevent falsification of the process image, process control, and site control. In the second embodiment, in addition to falsification prevention, process management, and site management, it is possible to easily and quickly convey information such as photography of the accident site and consultation on problems at the site. Therefore, instead of using the site code as the location information, we decided to use the authentication code for everything.

In the second embodiment, initial values are set in advance for process name, photo importance, notification, and actual measurement value input, and can be displayed and selected on the site terminal 2. For example, an accident process, an emergency consultation process, a snapshot process, and the like. That is, the initial values of the photo importance, notification, and actual measurement value input are set according to each. It is possible to simplify the manual input in the field by the field terminal 2 as much as possible and reduce the risk of erroneous input and erroneous conversion.
