Hereinafter, embodiments of the construction management system according to the present invention will be described in detail with reference to the drawings based on each embodiment. The present invention is not limited to the contents described below, and can be arbitrarily modified and implemented without changing the gist thereof. In addition, the various numerical values used in each embodiment are all examples, and can be changed in various ways as needed.

<Example 1>
Hereinafter, the configuration of the construction management system according to the present embodiment will be described with reference to FIGS. 1 and 2. Here, FIG. 1 is a schematic view showing the overall configuration of the construction management system according to the present embodiment. Further, FIG. 2 is a block diagram showing a server of the construction management system according to the present embodiment and a device connected to the server.

As shown in FIG. 1, the construction management system according to this embodiment includes position information of a heavy machine 1 such as a hydraulic excavator and a position of a transporter 2 such as a dump truck at a civil engineering construction site (hereinafter, also simply referred to as a construction site). It has a configuration in which information can be transmitted to the server 4 via a predetermined communication means 3. Specifically, the mobile terminal 5a installed on the heavy machine 1 and the mobile terminal 5b installed on the carrier 2 transmit radio waves from a plurality of positioning satellites 6 constituting a global positioning satellite system (GNSS: Global Navigation Satellite System). Receive. After that, the mobile terminals 5a and 5b that have received the radio waves transmit the position information obtained by the calculation using the radio waves to the communication company 8 that integrates the mobile communication network via the communication base station 7. Further, the communication company 8 transmits the location information to the server 4 via the communication line 9.

Here, the heavy machine 1 is a work machine capable of performing loading work on the transport machine 2, and is a machine having a plurality of work functions other than the loading work. Further, as the mobile terminals 5a and 5b, smartphones owned by the drivers of the heavy machine 1 and the carrier 2 can be used. Further, as the mobile terminals 5a and 5b, in addition to communication devices such as smartphones that are supposed to be carried, stationary communication devices that can be used by connecting to a cigarette power source may be used.

In this embodiment, since it is sufficient that the position information of the heavy machine 1 and the carrier 2 can be transmitted, the mobile terminals 5a and 5b do not need to have other high-precision sensors, and are provided with a relatively simple GPS sensor. It is also possible to use only terminals as mobile terminals 5a and 5b. By using such a terminal having only a simple sensor, the cost of the construction management system itself can be reduced.

Then, as shown in FIG. 1, in the construction management system according to the present embodiment, a work terminal 10 for confirmation by the manager of the civil engineering construction site is provided outside the civil engineering construction site. Since the work terminal 10 is provided with a communication device (not shown), it can communicate with the server 4 in both directions via the communication line 9. Therefore, the administrator who operates the work terminal 10 can access the server 4 via the communication line 9, display the work state of the civil engineering construction site on the work terminal 10, and confirm the contents. That is, the work terminal 10 functions as a display unit of the construction management system. Here, the work terminal 10 is a general computer that can perform various calculations and work as well as simply displaying the work state of the civil engineering construction site.

The work terminal 10 may be installed in a building installed inside a civil engineering construction site, or may be a mobile terminal owned by an administrator. In particular, since the mobile terminal owned by the administrator also serves as the work terminal 10, it is possible to grasp the work status of the civil engineering construction site selected by the administrator even when the administrator is working in another place or the like. become.

As shown in FIG. 2, the server 4 has a calculation unit 12, a first storage unit 13, a second storage unit 14, a network interface 15, and an external interface 16.

The arithmetic unit 12 is composed of, for example, a central processing unit (CPU) that performs various arithmetic processes. That is, the calculation unit 12 functions as a control device that collectively controls the server 4. For example, the arithmetic unit 12 performs arithmetic processing related to various data input from the network interface 15 according to the program stored in the first storage unit 13. In addition, the arithmetic unit 12 controls the network interface 15 and also controls the communication of the server 4 with respect to the communication line 9.

The first storage unit 13 is a general main memory (main storage device) that temporarily stores programs and various types of data. Specifically, the first storage unit 13 temporarily stores the program executed by the calculation unit 12, and further temporarily stores various data input to the server 4 and the calculation result by the calculation unit 12. For example, the first storage unit 13 is composed of a dynamic random access memory (DRAM: Dynamic Random Access Memory). The calculation result by the calculation unit 12 is, for example, a result of determining the positions of the heavy machine 1 and the carrier 2, which will be described later, and a result of an area chart showing the transition of these positions in time series.

On the other hand, the second storage unit 14 is a general storage (auxiliary storage device) that permanently stores various types of data. Specifically, the second storage unit 14 permanently stores the calculation result by the calculation unit 12. For example, the second storage unit 14 is composed of a hard disk drive (HDD) or a solid state drive (SSD).

Further, a display 17 which is a display device and a keyboard 18 which is an input device are connected to the external interface 16. The administrator of the server 4 can use and maintain the server 4 by operating the keyboard 18. In addition, the administrator can display the usage status, maintenance and inspection status, and the like on the display 17 and use the displayed output information. Another input device such as a mouse may be connected to the external interface 16, and an output device such as a printer may be connected to the external interface 16.

From such a configuration, in the construction management system according to the present embodiment, the calculation unit 12 of the server 4 executes the display program on the work terminal 10 at the work site, and works on the calculation result of the program via the communication line 9. It will be displayed on the terminal 10. Here, the method of displaying the calculation result on the work terminal 10 may be the display by the Web method or the execution of the program provided in the work terminal 10.

Next, with reference to FIGS. 3 to 5, various determinations, creation of an area chart, and display of determination results in the construction management system according to the present embodiment will be described. Here, FIG. 3 is a schematic view for explaining the construction site and the work area in this embodiment. Further, FIG. 4 is a functional block diagram of the construction management system according to this embodiment. FIG. 5 is a display example of an area chart in the construction management system according to this embodiment.

As can be seen from FIG. 3, in this embodiment, the construction site 100 has two work areas 110 and 120. In the work area 110, the heavy machine 1 and the carrier 2 perform the work. Specifically, in the work area 110, the heavy machine 1 excavates the earth and sand, and when the heavy machine 1 approaches the heavy machine 1 within a predetermined distance range, the heavy machine 1 is loaded into the transport machine 2 to perform the soil harvesting work. Become. On the other hand, in the work area 120, the carrier 2 will perform the work. Specifically, the work area 110 is loaded with earth and sand, and the transporter 2 unloads the earth and sand in the work area 120 and temporarily places the earth and sand. Further, the carrier 2 repeats the work in the work area 110 and the work area 120, and moves between the work area 110 and the work area 120 a plurality of times.

Then, in this embodiment, if it is determined from the position information of the heavy machine 1 and the carrier 2 input to the server 4 that the heavy machine 1 and the carrier 2 exist in the work area 110, the work area 110 It is judged that the work content "soil harvesting" is being carried out. On the other hand, when it is determined from the position information of the carrier 2 input to the server 4 that the carrier 2 exists in the work area 120, "temporary earth and sand storage" which is the work content of the work area 110 is carried out. It is judged that it is. These determinations will be described in detail in the flow described later.

Then, in order to realize the above-mentioned determination of whether or not the work is carried out and to enable the manager of the construction site to easily grasp the construction status of the construction site, the construction management system according to this embodiment is shown in FIG. It has various functional configurations shown in. Specifically, the construction management system according to this embodiment includes a data input unit 21, a heavy machine position determination unit 22, a carrier position determination unit 23, a work area setting unit 24, an area chart creation unit 25, and a work result display unit 26. Will be equipped.

The data input unit 21 acquires the position information of the heavy equipment 1 and the time information corresponding thereto via the communication line 9. In addition, the data input unit 21 also acquires the position information of the carrier 2 and the time information corresponding thereto. That is, the data input unit 21 corresponds to the network interface 15 of the server 4 and the calculation unit 12 that controls the network interface 15, and the function of the data input unit 21 is realized by the control of the network interface 15 by the calculation unit 12. Become. Note that each time information may be acquired by adding it to each position information without acquiring it as independent information.

The heavy equipment position determination unit 22 determines the position of the heavy equipment 1 at each time from the position information and time information of the heavy equipment 1 input to the data input unit 21. That is, the heavy machine position determination unit 22 corresponds to the calculation unit 12 of the server 4, and the position determination of the heavy machine 1 by the heavy machine position determination unit 22 is performed by the calculation unit 12 of the program stored in the first storage unit 13. The function related to is realized.

The carrier position determination unit 23 determines the position of the carrier 2 at each time from the position information and time information of the carrier 2 input to the data input unit 21. That is, the carrier position determination unit 23 corresponds to the calculation unit 12 of the server 4, and the carrier 2 by the carrier position determination unit 23 is executed by the calculation unit 12 of the program stored in the first storage unit 13. The function related to the position determination of is realized.

The work area setting unit 24 sets a work area in which the work is performed by at least one of the heavy machine 1 and the transport machine 2, and the work contents in the work area. In this embodiment, the work area 110 and the work area 120 are set in the construction site 100, the work in the work area 110 is set to "earth collecting", and the work in the work area 120 is set to "temporary earth and sand storage". To. In these actual settings, when the manager of the construction site operates the work terminal 10, various setting contents are input to the server 4 via the communication line 9 and the network interface 15, and the calculation unit 12 inputs the setting contents. This is done by storing in the first storage unit 13 or the second storage unit 14. That is, the work area setting unit 24 corresponds to the calculation unit 12, the first storage unit 13, the second storage unit 14, and the network interface 15 of the server 4, and the constituent devices of these servers 4 function. , Functions related to various settings by the work area setting unit 24 are realized.

The area chart creation unit 25 determines the position transition of the heavy machine 1 (that is, based on the setting information regarding the work area set by the work area setting unit 24 and the determination result of the position of the heavy machine 1 determined by the heavy machine position determination unit 22. , Time-series change of position) is created as a heavy equipment area chart (working machine area chart) that displays information related to the work area. Specifically, the heavy equipment area chart is a time-series display of the work area where the heavy equipment 1 is located in the upper part of FIG. Here, in the case shown in FIG. 5, it can be seen that the heavy machine 1 exists in the work area 110 in the time zone from 8:00 to 12:00 and the time zone from 13:00 to 17:00. Since the time zone from 12:00 to 13:00 is a lunch break, and since 17:00 is outside the working hours, the position information is due to the power of the mobile terminal 5a provided in the heavy equipment 1 being turned off. And the time information is not input to the server 4, and the work area is not displayed.

Similarly, the area chart creation unit 25 changes the position of the carrier 2 (that is, the position) based on the setting information regarding the work area and the determination result of the position of the carrier 2 determined by the carrier position determination unit 23. Create a carrier area chart that displays (time-series changes in) as information related to the work area. Specifically, the carrier area chart is a time-series display of the work area where the carrier 2 is located in the lower part of FIG. Here, in the case shown in FIG. 5, the carrier 2 exists in the work area 110 for 30 minutes from each of 8:00, 9:00, 10:00, 11:00, 13:00, 14:00, 15:00, and 16:00. You can see that you are doing it. Also, work for about 10 minutes from 8:40, 9:40, 10:40, 11:40, 13:40, 14:40, 15:40, and 16:40, respectively. It can be seen that it exists in the area 120.

As with the heavy equipment area chart, the power of the mobile terminal 5b provided on the carrier 2 is turned off because the time zone from 12:00 to 13:00 is a lunch break and after 17:00 is outside the working hours. As a result, the location information and the time information are not input to the server 4, and the work area is not displayed. On the other hand, in the portion where the work area is not displayed except for the time zone when the power is turned off, the carrier 2 is moving between the work area 110 and the work area 120 (that is, an area outside the set range). Corresponds to the time zone.

Then, as shown in FIG. 5, the area chart creation unit 25 creates an area chart in which the heavy equipment area chart and the carrier area chart are arranged side by side, and stores the area chart in the first storage unit 13 or the second storage unit. Record at 14. Regarding the creation of the area chart, the heavy equipment area chart and the form data to be the carrier area chart are combined in advance to form the form to be the area chart, and the heavy equipment area is created in the form of the area chart. Information corresponding to the chart and the carrier area chart (determination result described later) may be recorded.

For this reason, the area chart creation unit 25 corresponds to the calculation unit 12 of the server 4, and the heavy equipment by the area chart creation unit 25 is executed by the calculation unit 12 of the program stored in the first storage unit 13. A function related to the creation of an area chart, a carrier area chart, and an area chart combining these is realized.

The work result display unit 26 displays the area chart created by the area chart creation unit 25 on the work terminal 10 at the construction site. In these actual displays, the area chart stored in the first storage unit 13 or the second storage unit 14 is displayed on the network interface 15 and the communication line by the execution by the calculation unit 12 of the program stored in the first storage unit 13. It is transmitted to the work terminal 10 via 9, and the carrier area chart and the work machine area chart are arranged side by side, and the work is performed in a state where the administrator can easily confirm each work. That is, the work result display unit 26 corresponds to the calculation unit 12, the first storage unit 13, the second storage unit 14, and the network interface 15 of the server 4, and the constituent devices of these servers 4 function. , Functions related to various settings by the work result display unit 26 are realized.

In this embodiment, the area chart is displayed on the work terminal 10 with the transporter area chart and the work machine area chart as shown in FIG. 5 arranged one above the other. Then, in the area chart shown in FIG. 5, the manager of the construction site is in a time zone in which the time zone in which the heavy machine 1 exists in the work area 110 and the time zone in which the carrier 2 exists in the work area 110 overlap. , It can be determined that "soil harvesting", which is the work content of the work area 110, has been performed. Further, in the area chart shown in FIG. 5, the manager of the construction site performed "temporary earth and sand storage" which is the work content of the work area 120 during the time zone when the carrier 2 exists in the work area 120. It can be judged as a thing.

The area chart displayed on the work terminal 10 may be automatically displayed in the Web format by executing the program by the calculation unit 12 of the server 4 as described above. Further, the worker of the work terminal 10 (the manager of the construction site) executes the program of the work terminal 10, and the latest loading work record is acquired via the communication means 3, so that the area to the work terminal 10 is reached. The chart may be displayed.

Next, the construction management process in the construction management system according to the present embodiment will be described with reference to FIGS. 6 to 10. FIG. 6 is an area chart creation / display flow by the construction management system according to this embodiment. Further, FIG. 7 is a more specific determination processing flow of step S220 in FIG. 6, and FIG. 8 is a more specific determination processing flow of step S230 in FIG. Further, FIG. 9 is a more specific recording processing flow of step S240 in FIG. 6, and FIG. 10 is a more specific recording processing flow of step S250 in FIG.

First, when the area chart creation display flow is started, the work area and the work contents in the work area are set. In this embodiment, the work area 110 and the work area 120 are set at the construction site 100, the work content of "soil harvesting" is set for the work area 110, and the "soil temporary" is set for the work area 120. The work content of "placement" is set (FIG. 6: step S200). As described above, these settings are set and recorded by the manager of the construction site operating the work terminal 10 and the calculation unit 12 of the server 4. It should be noted that the calculation unit 12 of the server 4 automatically performs each setting and recording by the calculation unit 12 of the server 4 in consideration of, for example, the work situation of the previous day, without triggering the operation by the manager of the construction site. May be set.

Next, the data of the heavy machine 1 and the carrier 2 are input (FIG. 7: step S210). Specifically, the time information (time t1) at the time of acquiring the position information P1 (x1, y1, z1) and the position information P1 from the mobile terminal 5a arranged in the heavy machine 1 via the communication means 3 is transmitted to the server 4. Entered. Further, the position information P2 (x2, y2, z2) and the time information (time t2) at the time of acquisition of the position information P2 are input to the server 4 from the mobile terminal 5b arranged in the carrier via the communication means 3. ..

Next, the calculation unit 12 determines the position of the heavy machine 1 based on the input position information P1 of the heavy machine 1 (FIG. 6: step S220). As a more specific determination flow, first, the range of the work area 110 set in step S200 and the input position information P1 are compared, and it is determined whether or not the heavy machine 1 exists in the work area 110. (Fig. 7: Step S221). When the heavy machine 1 exists in the work area 110 (step S221: Yes), the position flag F1 of the heavy machine 1 is set to the "work area 110" (FIG. 7: step S222).

On the other hand, when the heavy machine 1 does not exist in the work area 110 (step S221: No), the range of the work area 120 set in step S200 is compared with the input position information P1, and the heavy machine 1 is in the work area 120. It is determined whether or not it exists in (FIG. 7: step S223). When the heavy machine 1 exists in the work area 120 (step S223: Yes), the position flag F1 of the heavy machine 1 is set to the "work area 120" (FIG. 7: step S224). Here, in the present embodiment, since it is not assumed that the heavy machine 1 exists in the work area 120 and works, the determination of an unexpected position (for example, step S223 and step) is performed from the viewpoint of simplifying the processing flow. S224) may be omitted.

When the heavy machine 1 does not exist in the work area 120 (step S223: No), it is assumed that the heavy machine 1 does not exist in the set work areas 110 and 120 and exists in other areas, and the position flag F1 of the heavy machine 1 is set. It is cleared and set to "0" (FIG. 7: step S225).

When the position determination of the heavy machine 1 is completed, the position of the carrier 2 is determined based on the position information P2 of the carrier 2 input by the calculation unit 12 (FIG. 6: step S230). Specifically, as in the position determination flow of the heavy machine 1, whether or not the carrier 2 exists in the work area 110 (FIG. 7: step S231) and whether or not the carrier 2 exists in the work area 120. (FIG. 7: Step S233), or the position flag F2 corresponding to each work area is set (FIG. 7: Steps S222, S234, S235). Since the position determination flow of the carrier 2 is the same as the position determination flow of the heavy machine 1, detailed description thereof will be omitted.

Next, by executing the program of the calculation unit 12, the position determination result of the heavy machine 1 is recorded in the area chart, and the area chart in the recorded state is stored in the first storage unit 13 or the second storage unit 14 (FIG. 6: Step S240). As a specific processing flow, first, it is determined whether or not the position flag F1 of the heavy machine 1 is set to the "work area 110" (FIG. 9: step S241). When the position flag F1 of the heavy machine 1 is set to the "work area 110" (step S241: Yes), the current position flag F1 of the heavy machine 1 is the same as the position flag F1-1 in the previous processing flow of the heavy machine 1. It is determined whether or not (FIG. 9: step S242). Here, since the creation display flow of this area chart is repeatedly executed periodically (for example, at intervals of several seconds) unless there is an end instruction described later, the previous position flag F1-1 is one time before. It is a position flag set in the processing cycle.

When the current position flag F1 and the previous position flag F1-1 are the same (F1 = F1-1) (step S242: Yes), the heavy equipment area chart part of the area chart is displayed from the previous time t1-1 this time. The position up to the time t1 of is set in the "work area 110" (step S243). That is, since the current position flag F1 and the previous position flag F1-1 are the same, it is determined that the heavy machine 1 was present in the work area 110 from the time t1-1 to the time t1. Then, as the determination result, a setting is made to display the "work area 110" between the time t1-1 and the time t1 on the heavy equipment area chart.

On the other hand, when the current position flag F1 and the previous position flag F1-1 are not the same (step S242: No), the position at the current time t1 is set to "work area 110" in the heavy equipment area chart portion of the area chart. (Step S244). That is, since the current position flag F1 and the previous position flag F1-1 are different, it is determined that the heavy machine 1 moves between the time t1-1 and the time t1 and exists in the work area 110 at the time t1. Will be done. Then, as the determination result, a setting is made to display the position of the heavy equipment area chart at time t1 as "work area 110".

Next, when the position flag F1 of the heavy machine 1 is not set to the "work area 110" (step S241: No), it is further determined whether or not the position flag F1 of the heavy machine 1 is set to the "work area 120". (Fig. 9: Step S245). When the position flag F1 of the heavy machine 1 is set to the "work area 120" (step S245: Yes), the current position flag F1 of the heavy machine 1 is the same as the position flag F1-1 in the previous processing flow of the heavy machine 1. It is determined whether or not (FIG. 9: step S246).

When the current position flag F1 and the previous position flag F1-1 are the same (F1 = F1-1) (step S246: Yes), the heavy equipment area chart part of the area chart is displayed from the previous time t1-1 this time. The position up to the time t1 is set in the "work area 120" (step S247). That is, since the current position flag F1 and the previous position flag F1-1 are the same, it is determined that the heavy machine 1 was present in the work area 120 from the time t1-1 to the time t1. Then, as the determination result, a setting is made to display the "work area 120" between the time t1-1 and the time t1 on the heavy equipment area chart.

On the other hand, when the current position flag F1 and the previous position flag F1-1 are not the same (step S246: No), the position at the current time t1 is set to "work area 120" in the heavy equipment area chart portion of the area chart. (Step S248). That is, since the current position flag F1 and the previous position flag F1-1 are different, it is determined that the heavy machine 1 moves between the time t1-1 and the time t1 and exists in the work area 120 at the time t1. Will be done. Then, as the determination result, a setting is made to display the position of the heavy equipment area chart at time t1 as "work area 120".

When the position flag F1 of the heavy machine 1 is not set as the "work area 120" (step S245: No), and after the processing of steps S243, S244, S247, and S248, the position flag F-1 is set to the current position flag F1. The value of is set (FIG. 9: step S249). That is, in step S249, the current position flag F1 is reset as the previous position flag so that the current position flag F1 can be used in the next processing flow.

In this embodiment, since it is not assumed that the heavy machine 1 exists in the work area 120 to work, the determination of an unexpected position (for example, steps S245 to S248) is performed from the viewpoint of simplifying the processing flow. May be omitted.

When the determination result of the heavy machine 1 is recorded in the heavy machine area chart, the position determination result of the carrier 2 is recorded in the area chart by the program execution of the calculation unit 12, and the area chart in the recorded state is the first storage unit. It is stored in 13 or the second storage unit 14 (FIG. 6: step S250). Specifically, as in the case of recording the determination result of the heavy machine 1 on the area chart, whether or not the position flag F2 is the work area 110 (FIG. 10: step S251) and whether or not the position flag F2 is the work area 120 (FIG. 10: step S251). FIG. 10: Step S255), comparison with the previous position flag F2 (FIG. 10: steps S252, S256), setting of a work area in the carrier area chart (FIG. 10: steps S253, S254, S257, S258), And the current position flag F2 is reset to the previous position flag (FIG. 10: step S259). Since the recording flow of the determination result of the carrier 2 is the same as the recording flow of the heavy machine 1, detailed description thereof will be omitted.

When the determination result of the carrier 2 is recorded in the carrier area chart, the update of the area chart consisting of the heavy machine area chart and the carrier area chart is completed, and the updated area chart (state shown in FIG. 5) is displayed on the work terminal. It is displayed at 10 (FIG. 5: step S260). After that, if there is no end instruction of the present creation display flow (step S270: No), the process returns to step S210 and the creation display flow is repeated. The repeating cycle can be appropriately changed depending on various conditions such as the situation of the construction site 100, the distance between each work area, and the performance of the heavy machine 1 and the carrier 2.

As described above, in the construction management system according to the present embodiment, the heavy equipment area chart in which the position of the heavy equipment 1 is displayed as information related to the work area and the position of the carrier 2 are displayed as information related to the work area. An area chart is created in which the carrier area chart is arranged side by side, and the area chart is displayed to the manager of the construction site. Therefore, the manager of the construction site can easily grasp the work contents of the heavy machine 1 and the carrier 2 from the area chart. Then, the manager of the construction site can also plan the work management and optimization of the entire construction site from the grasped work contents.

For example, the manager of the construction site compares the work plan of the day with the number of times of transportation by the carrier 2 by checking the updated area chart at the end of the work of the day, and the number of times as planned. It can be easily determined whether the work is being performed. In addition, the movement time of the two work areas can be easily grasped from the distance between the two work areas displayed on the carrier area chart, and the obstacle of the carrier 2 and the obstacle of the road condition on which the carrier 2 travels can be easily grasped. It is possible to easily find out the possibility that such a situation has occurred.

Furthermore, the construction site manager can determine the presence or absence of work delays and failures by checking the updated area chart during the work hours, and can add additional items in response to the delays or failures. Measures such as throwing in a carrier can be taken.

Then, in the construction management system according to this embodiment, the area chart is created only by acquiring the position information and the time information of the heavy machine 1 and the carrier 2, so that the construction site can be broadly viewed with a relatively simple configuration. It is possible to construct an observation system, simplify the system itself, and reduce costs.

In the above-described first embodiment, it is assumed that the work related to one heavy machine 1 and one carrier 2 is managed and grasped, but a plurality of heavy machines and a plurality of carriers are used depending on the construction site. In some cases. Further, in the above-described first embodiment, two work areas are set at one construction site 100, which is a constant enclosed space, but two work areas are included so as to include a plurality of work areas connected by a general transportation road. In some cases, the construction site is constructed. A construction management system assuming such a case will be described below with reference to FIGS. 11 to 15 as the second embodiment.

That is, as a further becomes different from that in Example 1, with the mobile terminal 5a ₁ independent in each vehicle of heavy equipment 1a _1, 1a _2, 5a ₂ are arranged, each vehicle transporter _2a 1 to 2A region _n, independently The mobile terminals 5b _{1 to} 5b _n are arranged.

Further, as shown in FIG. 12, in this embodiment, there are three work areas 130, 140, 150 separated from each other. The three work areas 130, 140, 150 are connected by a general transportation road 160.

Here, in the work area 130, work related to embankment such as constructing an embankment is performed. Further, in the work area 140, work related to soil collection for excavating and carrying out earth and sand used for embankment work is performed. Further, in the work area 150, the work of discarding the excrement (for example, rubble) that is not suitable for embankment is performed among the earth and sand excavated in the work area 140. In this embodiment, each carrier loaded with earth and sand by the heavy machine 1a ₂ in the work area 140 travels on the transportation road 160 to reach the work area 130, unloads the earth and sand in the work area 130, and the heavy machine 1a ₁ moves. A work plan is envisioned to embank the earth and sand to build an embankment. Meanwhile, earth removal, which is determined to be unsuitable for embankment in the working area 140, by heavy equipment 1a ₁ loaded on another transporter, the transporter of dumping is loaded is the work area 150 traveling haul road 160 A work plan is envisioned to reach and unload the soil in the work area 150.

Then, in the present embodiment, the position information of the heavy equipment 1a _1, 1a ₂ and transporter _2a 1 to 2A region _n to be input to the server 4, either one or transporter of heavy machinery is present in the work area 130 If it is determined that the work area 130 is being used, it is determined that the work content of the work area 130, "filling", has been carried out. Further, it is determined that the position information of the heavy equipment 1a _1, 1a ₂ and transporter 2a ₁ to 2A region _n to be input to the server 4, either one or transporter of heavy machinery is present in the work area 140 Then, it is determined that "soil harvesting", which is the work content of the work area 140, is being carried out. Furthermore, the position information of the transporter 2a ₁ to 2A region _n to be input to the server 4, when any one of the transporter is determined to be present in the working area 150, a work in the work area 150 "discharge It is judged that "soil" is being carried out. These determinations will be described in detail in the flow described later.

Next, as shown in FIG. 13, the construction management system according to the present embodiment includes a data input unit 21, a heavy machine position determination unit 22, a carrier position determination unit 23, a work area setting unit 24, and an area chart creation unit 25. In addition to the work result display unit 26, an ID management unit (identification information management unit) 27 is further provided. ID management unit 27 manages the identification information attached to heavy equipment 1a _1, 1a ₂ and transporter _2a 1 _{~2a n.} For example, ID management unit 27, heavy equipment 1a _1, 1a ₂ mobile terminal 5a ₁ provided, 5a _2, and the transporter _2a 1 to 2A region portable terminal _5b 1 provided _{n ~5b n} calling number (Smartphone If so, the telephone number) is acquired, and the heavy machine ID is set for each heavy machine corresponding to each calling number, and the carrier ID is set for each carrier. Further, the ID management unit 27 manages the position information and the time information, which are the data input to the data input unit 21, by allocating them to each heavy machine ID or carrier ID.

That is, the data input unit 21, each data without being distinguished from heavy equipment 1a _1, 1a ₂ and transporter _2a 1 to 2A region _n is inputted, ID management unit 27, heavy equipment 1a ₁ the respective data , corresponding to 1a ₂ or transporter _2a 1 to 2A region _n, it is a function of differentiated management for each heavy equipment ID or transporter ID. Therefore, the ID management unit 27 corresponds to the network interface 15 of the server 4, the calculation unit 12 that controls the network interface 15, and the second storage unit 14 that records each ID and the transmission number of each mobile terminal in association with each other. The function of the ID management unit 27 is realized by controlling the network interface 15 by the calculation unit 12 and storing the data in the second storage unit 14.

Then, the heavy equipment position determination unit 22, the carrier position determination unit 23, and the area chart creation unit 25 correspond to each heavy equipment ID or each carrier ID (that is, based on each identification information), and the heavy equipment 1a ₁ , 1a performing each judgment and processing for each of the ₂ and transporter _2a 1 _{~2a n.} Further, the area chart creation unit 25 creates a heavy machine area chart of all the target heavy machines and a carrier area chart of all the target carriers, and completes an area chart in a state where these are combined and arranged. To do. For example, as shown in FIG. 14, the positions of each heavy machine and each carrier are displayed by the work areas 130, 140, 150 between 8:00 and 17:00.

As shown in FIG. 14, in this embodiment, the heavy equipment area chart of the heavy equipment 1a ₁ is displayed in chronological order at the top, and the heavy equipment area chart of the heavy equipment 1a ₂ is displayed in chronological order at the bottom. Further, between the two heavy areas chart, transporter area chart corresponding to the respective transporter 2a ₁ to 2A region _n are displayed in chronological order. Here, in the case shown in FIG. 14, it can be seen that the heavy machine 1a ₁ exists in the work area 130 in the time zone from 8:00 to 12:00 and the time zone from 13:00 to 17:00. Further, it can be seen that the heavy machinery 1a ₂ exists in the work area 140 in the time zone from 8:00 to 12:00 and the time zone from 13:00 to 17:00.

Similarly, in the case shown in FIG. 14, it can be seen that the carriers 2a ₁ and 2a ₂ alternately exist in the work area 140 and the work area 130. That is, the carriers 2a ₁ and 2a ₂ work (pick up soil) in the work area 140, then travel on the transport road 160 and arrive at the work area 130 to perform the work (filling), and these works are performed at 8 o'clock. It can be seen that it repeats between 17:00 and 17:00. Further, the transporter 2a _n, in a predetermined time period, the work area 140, work area 150, a work area 130, it can be seen that present in the work area 140 and the work area 150,. That is, the transporter 2a _n, after working (soil picking of dumping) in the work area 140, the task of performing the work arrives at the work area 150 traveling haul road 160 (dumping) the morning and in the afternoon It can be understood that it is done once. Further, it can be grasped that the soil is collected in the work area 140 in the morning, travels on the transportation road 160, arrives at the work area 130 in the afternoon, and is filled.

Next, the construction management process in the construction management system according to the present embodiment will be described with reference to FIG. In the area chart creation display flow in this embodiment, processing related to ID is added as compared with the case of Example 1.

First, the work area and the work content are set in the same manner as in the first embodiment (FIG. 15: step S200a). In this embodiment, the work content of "filling" is set in the work area 130, the work content of "soil harvesting" is set in the work area 140, and the work content of "soil removal" is set in the work area 150. ..

Then, the input data of heavy equipment 1a _1, 1a ₂ and transporter _2a 1 to 2A region _n is performed (FIG. 15: Step S210a). Specifically, the position information P1a ₁ (x1a ₁ , y1a ₁ , z1a ₁ ), P1a ₂ (x1a ₂ ) from the mobile terminals 5a ₁ , 5a ₂ arranged on the heavy equipment 1a ₁ , 1a ₂ via the communication means 3. , Y1a ₂ , z1a ₂ ) and the time information (time t1a ₁ , t1a ₂ ) at the time of acquisition of the position information are input to the server 4. Furthermore, through the communication means 3, the position of the transporter _2a 1 to 2A region _n to arranged the portable terminal _5b 1 _{~5b n} information _{P2a 1 (x2a 1, y2a 1} , z2a 1) ~P2a n (x2a n, y2a _{n, z2a n),} and time information at the time of acquisition of the position information (time _t2a 1 _{~t2a 2)} is input to the server 4.

Next, similarly to step S220 and step S230 of the first embodiment, is performed (step S220A) determination of the position of the heavy equipment 1a _1, 1a _2, followed by the position of the transporter _2a 1 to 2A region _n determined It is performed (step S230a). Then, similarly to step S240 and step S250 of Example 1, heavy equipment 1a _1, 1a ₂ of the decision result is recorded in the area chart (step S240a), followed by the transporter _2a 1 to 2A region _n of the determination result area chart Is recorded in (step S250a).

Then, when the update of the area chart including the heavy equipment area chart and the transporter area chart is completed through each of the above steps, the updated area chart (state shown in FIG. 14) is displayed on the work terminal as in step S260 of the first embodiment. It is displayed in 10 (step S260a). After that, if there is no end instruction of the present creation display flow (step S270a: No), the process returns to step S210a and the creation display flow is repeated. As in the case of the first embodiment, the repetition cycle can be appropriately changed depending on various conditions such as the condition of the construction site, the distance between each work area, and the performance of the heavy machine and the carrier.

As described above, in the construction management system according to the present embodiment, two heavy areas chart displayed as information related to each position of the heavy equipment 1a _1, 1a ₂ in the work area, the transporter 2a ₁ of to 2A region _n An area chart is created in which each position of the above is arranged side by side with n transporter area charts displaying information related to the work area, and the area chart is displayed to the manager of the construction site. Therefore, the administrator of the construction site can easily grasp the work by heavy equipment 1a _1, 1a ₂ and transporter _2a 1 to 2A region _n from the area chart. Then, the manager of the construction site can also plan the work management and optimization of the entire construction site from the grasped work contents.

Further, in the construction management system according to the present embodiment, as in the case of the first embodiment, the occurrence of various delays or failures can be easily found, and an additional carrier is introduced in response to the delays or failures. Etc. can be taken. Further, as in the first embodiment, it is possible to construct a system for observing the construction site from a broad perspective with a relatively simple configuration, and it is also possible to simplify the system itself and reduce the cost.

<Example 3>
In the first and second embodiments, the manager of the construction site who confirms the area chart which is the determination result of the positions of the heavy machine and the carrier is supposed to read the work status of the heavy machine and the carrier, but the server. It is also possible to analyze the area chart on the 4th side, display the result so that the work situation can be grasped more easily, and change the work plan. A construction management system in which such a case is assumed will be described below with reference to FIGS. 16 to 23 as the third embodiment.

Here, FIG. 16 is a functional block diagram of the construction management system according to this embodiment. 17 and 18 are explanatory views for explaining the analysis of the area chart. Further, FIG. 19 is a discriminant analysis flow by the construction management system according to the present embodiment, FIG. 20 is a more specific setting flow of step S280 of FIG. 19, and FIG. 21 is a more specific flow of step S290 of FIG. FIG. 22 is a more specific work plan change flow of step S300 of FIG. FIG. 23 is an example of displaying work records in the construction management system according to this embodiment. The same description as in Example 1 and Example 2 will be omitted.

First, also in this embodiment, the construction site shown in FIGS. 11 and 12 of the second embodiment and the work at the construction site are assumed. In this embodiment, the number of transporters is set to 3 (n = 3) from the viewpoint of convenience of explanation.

On the other hand, in this embodiment, the work plan is set and whether or not to change the work plan is determined based on the analysis result of the area chart. In order to realize such a function, as shown in FIG. 16, the construction management system according to this embodiment includes a data input unit 21, a heavy machine position determination unit 22, a carrier position determination unit 23, and a work area setting unit 24. In addition to the area chart creation unit 25, the work result display unit 26, and the ID management unit 27, a work plan setting unit 28, an area chart analysis unit 29, and a work plan change unit 30 are provided.

Work plan setting unit 28 sets the work plan by heavy equipment 1a _1, 1a ₂ and transporter _2a 1 _{~2a n.} For example, the number and amount of embankment work and the number and amount of soil removal work can be set in units of one day or half a day. In these actual settings, when the manager of the construction site operates the work terminal 10, various setting contents are input to the server 4 via the communication line 9 and the network interface 15, and the calculation unit 12 inputs the setting contents. This is done by storing in the first storage unit 13 or the second storage unit 14. That is, the work plan setting unit 28 corresponds to the calculation unit 12, the first storage unit 13, the second storage unit 14, and the network interface 15 of the server 4, and the constituent devices of these servers 4 function. , Functions related to various settings by the work plan setting unit 28 are realized.

The area chart analysis unit 29 is set in the work area setting unit 24 based on the transporter area chart and the work machine area chart (that is, the area chart in the state of being displayed side by side) created by the area chart creation unit 25. Analyze whether or not the work is being carried out. In addition, the area chart analysis unit 29 creates a work content chart in which the analysis result corresponds to the passage of time. Therefore, the area chart analysis unit 29 corresponds to the calculation unit 12 of the server 4, and the analysis and work contents by the area chart analysis unit 29 are executed by the calculation unit 12 of the program stored in the first storage unit 13. Functions related to chart creation are realized.

Here, the work content chart is a graph showing whether or not the work content is carried out for each work area, which is shown in FIG. 17B, in chronological order. As a method of creating the work content chart (that is, an area chart analysis method), first, in the area chart shown in FIG. 17A, a portion (time zone) in which the heavy machine and the carrier exist in the same work area. ) Is extracted, and the extracted time zone is displayed for each work area. That is, in this embodiment, as shown in FIG. 17A, the portion surrounded by A in the carrier area chart of the carrier 2a ₁ and the portion surrounded by A'in the heavy machine area chart of the heavy machine 1a ₂ are surrounded. Since the parts overlap, it can be determined that the heavy machine 1a ₂ and the carrier 2a ₁ exist in the work area 140 from 8 o'clock to 8:30, and the overlapping part is the work area 140 of the work content chart ( It is displayed as the part surrounded by A'' in the time series of earth and sand removal). Similarly, the overlapping portion between the heavy equipment area chart of the heavy equipment 1a ₂ and the transportation equipment area chart of the transportation equipment 2a _{1 to} 2a ₃ in other time zones is also extracted and displayed in the time series of the work area 140.

Further, in this embodiment, as shown in FIG. 17A, the portion surrounded by B in the carrier area chart of the carrier 2a ₁ and the portion surrounded by B'in the heavy machine area chart of the heavy machine 1a ₁ are surrounded. Since the parts overlap, it can be determined that the heavy machine 1a ₁ and the carrier 2a ₁ exist in the work area 130 from 9 o'clock to 9:30, and the overlapping part is the work area 130 of the work content chart ( It is displayed as the part surrounded by B'' in the time series of earth and sand for embankment). Similarly, the overlapping portion of the heavy machine area chart of the heavy machine 1a ₁ and the carrier area chart of the carriers 2a _{1 to} 2a ₃ in other time zones is also extracted and displayed in the time series of the work area 130.

In other words, the area chart analysis unit 29 calculates the logical product of the positions of the heavy machinery and the carrier for each work area, and the work of embankment in the work area 130 or soil collection in the work area 140 is performed. It means that we are analyzing whether or not it is.

Further, in the work area 150, since the soil removal work is set so that the heavy machinery does not need to work, it can be estimated that the soil removal work is carried out if the carrier exists, and the carrier The display of the work area 150 in the area chart is displayed as it is as the display of the work in the work area 150. In this embodiment, the portion where the carrier 2a ₃ exists in the work area 150 (the time zone from 10:00 to 10:30 and the time zone from 15:30 to 16:00) is the work content chart. It is displayed in the time series of the work area 150 (exhaust of unnecessary soil and the like).

In other words, the area chart analysis unit 29 analyzes whether or not the soil removal work in the work area 150 is performed only by the position of the carrier in the work area 150 where the heavy machinery is not planned to exist. You will be doing.

When such a work area chart is created, the relevance of each work area is extracted in consideration of the movement of the carrier. Specifically, the carrier 2a ₁ exists in the work area 140 from 8 o'clock to 8:30, and then exists in the work area 130 from 9 o'clock to 9:30. It can be determined that the portion surrounded by A ″ in the time series of the work area 140 and the portion surrounded by B ″ in the time series of the work area 130 correspond to each other. Therefore, as shown by the arrow C in FIG. 17B, the earth and sand collected and carried out in the work area 140 in the time zone of A ″ are carried in in the work area 130 in the time zone of B ″. It is analyzed that it has been filled. Similarly, work in other time zones can also be associated (indicated by arrows in FIG. 17B), and the flow of each work content is analyzed.

From the above, the area chart analysis unit 29 determines whether or not the set work content is implemented based on the presence or absence of the overlapping display portion with the transport machine area chart and the work machine area chart. That is, the work area chart defined by the overlapping display portion is displayed in the form of progress of each work area and each work content, and the progress is analyzed.

The area chart analysis unit 29 also analyzes the work status based on the movement time from a predetermined work area to another work area in the carrier area chart. Specifically, as shown in FIG. 18, the travel time from the work area 130 to the work area 140 of each carrier is calculated, and it is analyzed from the travel time whether or not an obstacle occurs in the operation of the carrier. Has been done. In this embodiment, the moving time Δt1 of the carrier 2a ₃ (the part shown by E in FIG. 18) is the moving time Δt2 of the carrier 2a ₁ (the part shown by F in FIG. 18) and the moving time of the carrier 2a ₂ . It is longer than Δt0 (the part indicated by G in FIG. 18). Therefore, it can be analyzed that some kind of failure has occurred in the operation of the carrier 2a ₃ , and further, since the moving time Δt2 of the carrier 2a ₁ is equivalent to the moving time Δt0 of the carrier 2a ₂ , the failure. Can also be analyzed as temporary.

The work plan change unit 30 compares the work plan set by the work plan setting unit 28 with the work content chart created by the area chart analysis unit 29, determines whether or not to change the work plan, and determines whether or not to change the work plan. Decide what to change. Therefore, the work plan change unit 30 corresponds to the calculation unit 12 of the server 4, and the work plan change unit 30 determines and changes the program by executing the program stored in the first storage unit 13. The function related to is realized. For example, if a service failure, which is analyzed from the moving time Δt1 of transporter 2a ₃ shown in FIG. 18 was analyzed to not solved, the working plan change unit 30 to perform the change of work program, such as changing the travel course become.

Next, the construction management process in the construction management system according to the present embodiment will be described with reference to FIG. Here, in the processing flow in the present embodiment, the work plan setting (step S280), the area chart analysis (step S290), and the work plan change (step S300) are added as compared with the case of the second embodiment. The contents of steps S200b, S210b, S220b, S230b, S240b, and S250b are the same. Further, the display of the work result (step S310) corresponds to step 260a of the second embodiment, and the confirmation of the completion of the work (step S320) corresponds to the step 270a of the second embodiment. Therefore, in the following, step S280, step S290, and step S300 will be described in detail.

When the setting of the work area and the work content (FIG. 19: step S200b) is completed, the work plan is set (FIG. 19: step S280). Specifically, as shown in step S2800 of FIG. 20, the planned embankment work amount for today (working day) in the work area 130 is set to Gm ³ . Further, based on the set embankment work amount planned value, the embankment carry-in frequency planned value is set to N times. Here, the planned value of the number of embankments brought in is calculated from the formula of N = G / G0. G0 is the standard load capacity of the carrier. Further, the planned value of the number of embankments carried in in the morning of the work day is set to M times, and the planned value of the number of embankments carried in in the afternoon of the work day is set to K times (K = NM). Then, today's soil removal number planned value in the work area 150 is set to S times.

Each of these planned values may be appropriately determined by the manager of the construction site, or may be automatically determined according to the work results of the previous day. Further, in this embodiment, since the work contents are embankment and soil discharge, the above-mentioned embankment carry-in count planned value and soil discharge count planned value are set, but the setting contents are set according to the work content. Will be changed accordingly.

Next, when the area chart is updated, the area chart is analyzed (FIG. 19: step S290). Specifically, the area maps of heavy machinery and transporters (that is, heavy machinery area charts and transporter area charts) are analyzed by the area maps for each work area by the work area chart creation method and analysis method as described above. Then, the analysis result is recorded in the first storage unit 13 or the second storage unit 14, and further, the work area chart and the analysis result such as the occurrence status of the failure are displayed on the work terminal 10 (FIG. 21: step S2910). ).

Subsequently, totaling is performed for each work content based on the work area chart (FIG. 21: step S2920). In the work situation shown in FIG. 17B, the number of embankments carried in in the morning in the work area 130 is 4 times, the number of embankments carried in the afternoon is 5 times, and the total number of embankments carried in is 9 times. In addition, the number of embankments carried out in the morning in the work area 140 is 6 times, the number of embankments carried out in the afternoon is 5 times, and the total number of embankments carried out is 11 times. Further, the number of times of soil removal in the morning in the work area 150 is calculated as one, the number of times of soil removal in the afternoon is one, and the total number of times of soil removal is two.

When the aggregation is completed for each work content, a determination process of whether or not to change the work plan is performed from the analysis result of the area chart (FIG. 19: step S300). For example, in this embodiment, a method is adopted in which the work situation in the morning is observed and analyzed, and the work plan in the afternoon is reviewed according to the result.

Specifically, first, it is determined whether the number of embankments brought in in the morning is as planned (FIG. 22: step S3010). That is, it is determined whether or not the number of embankment loadings P in the morning is equal to the planned value m. When the number of embankment loadings P in the morning is equal to or greater than the planned value m, the work plan is not changed (FIG. 22: steps S3020 and S3030). If the number of embankments carried in in the morning P is larger than the planned value m, the work plan may be changed in step S3030 to reduce the number of embankments carried in in the afternoon.

On the other hand, when the number of embankments brought in in the morning P is less than the planned value m, additional arrangements for the carrier are made (FIG. 22: step S3040). The additional arrangement may be made by the manager of the construction site by displaying the necessity of the additional arrangement on the work terminal 10, or may be automatically made by the calculation unit 12 of the server 4.

When the processes of steps S3020, S3030, and S3040 are completed, it is determined whether or not there is a traffic obstacle between the work areas (FIG. 22: step S3050). Specifically, it is determined whether or not the movement time Δt between work areas is within a preset range (Δt _min ≦ Δt ≦ Δt _max ) and that state continues. After that, if there is no traffic obstacle, the work plan is not changed (FIG. 22: step S3060), and if there is a traffic obstacle, the work plan is changed (FIG. 22: step S3070). For example, in the situation of FIG. 18, although Δt1 is longer than the normal time Δt0, Δt2 has returned to Δt0, so that it is determined that there is no traffic hindrance.

Regarding the method for determining whether or not the work plan has been changed, the criteria for determining whether or not the work plan has been changed will be appropriately determined depending on how the issues at the construction site are set at the time of determination, regardless of the number of times the embankment is carried in or whether or not there is a traffic obstacle. It is possible to change.

When the determination process for changing the work plan is completed, the work result from the analysis result of the area chart is displayed on the work terminal 10 via the communication means 3 (FIG. 19: step S310). Specifically, as shown in FIG. 23, the work content, work time, number of work times, and work soil amount are displayed for each work area. The working time, the number of working times, and the amount of working soil will be determined in the analysis step (S290) of the area chart described above.

As described above, in the construction management system according to the present embodiment, the created area chart is automatically analyzed by the calculation unit 12 of the server 4, and the analysis result is provided to the manager of the construction site. Become. As a result, the manager of the construction site can more easily grasp the work status at the construction site, and further, it is possible to optimize the work status of the entire construction site at an early stage from the work contents.

Further, in the construction management system according to the present embodiment, since the calculation unit 12 of the server 4 determines whether or not the work plan has been changed, the burden on the manager at the construction site is reduced and the failure at the construction site is early. It will be possible to eliminate it.

The contents of the analysis and the change of the work plan in this embodiment can also be applied to the construction site where one heavy machine and one carrier work as in the first embodiment. That is, the processing related to the analysis and the change of the work plan in the third embodiment may be added to the construction management system of the first embodiment.

Further, in any of the above-described embodiments, it was assumed that the mobile terminal was installed in the heavy machine and the carrier, but the worker at the construction site was also allowed to carry the mobile terminal, and the worker An area chart may be created including the position information. This makes it possible to manage the work of the situation including workers in addition to heavy machinery and transporters.
