[Summary]
As described above, according to the present invention, electricity usage information such as ON / OFF of the electricity usage state and the amount of electricity is acquired from a power source such as a distribution board that supplies power to a plurality of devices, and the acquired electricity usage. By analyzing the information, the corresponding tunnel construction process can be determined and recorded. In other words, according to the present invention, the operation information of the equipment or the equipment group can be acquired only from the time series information of the electric power consumed in the corresponding tunnel construction process by the equipment or the equipment group used in the tunnel construction. When recording information based on the process, no human work is required, and the tunnel construction process can be easily and quickly grasped and recorded at any time.

If the cycle time of the tunnel is managed according to the present invention, information based on the tunnel construction process can be accurately acquired in real time without any manual work. Therefore, based on the highly accurate real-time recording, the construction process can be performed. Work efficiency can be further improved by performing progress management or scheduling management.
For example, ready-mixed concrete used for concrete spraying work on a face in tunnel construction is prepared near the wellhead and transported from the wellhead to the vicinity of the face by a mixer truck. If the tunnel length is as long as 10 km, the work time required to transport the ready-mixed concrete by the mixer truck will be large. Therefore, depending on the timing of ordering ready-mixed concrete, there is a possibility that a waiting time may occur on the face side, which may cause a time loss in efficiently performing the spraying work on the face.

On the other hand, according to the present invention, it is possible to acquire information based on the tunnel construction process at any time in the vicinity of the wellhead in real time. Therefore, by managing the progress or scheduling of the construction process based on the record, the kneading timing of ready-mixed concrete can be set quickly and appropriately. Therefore, according to the present invention, it is possible to manage the construction process based on the record of the tunnel construction process at any time to further improve the work efficiency.

Here, as the reference time for managing the cycle time such as progress management or scheduling management, for example, the measured average value of the cycle time in a plurality of devices or a group of devices used in the tunnel construction can be mentioned.
In addition, the power consumed by the equipment used in tunnel construction can be easily measured and obtained by a power meter installed in advance. In addition, the power meter can be easily installed in the equipment. Therefore, the electricity usage information consumed by a plurality of devices or device groups can be obtained with a simple configuration.

As described above, according to the present invention, when recording a tunnel construction process, it is possible to quickly record the tunnel construction process at any time without using human work. In addition, based on the record, the tunnel construction process can be managed at any time.

Then, a power meter 1a to 1e is attached to each distribution board 2V to 2Z. Each of the power meters 1a to 1e can acquire ON / OFF information of the electricity usage state acquired from the device corresponding to one tunnel construction process or the power source corresponding to the device group, and output it as a digital signal. ing.

A management device 10 that executes a cycle time management process described later is connected to the output units of the power meters 1a to 1e. The management device 10 is configured to be able to acquire ON / OFF digital signals output from the power meters 1a to 1e. In the present embodiment, the management device 10 corresponds to the "tunnel construction process recording device" and the "tunnel cycle time management device" described in the means for solving the above problems.

The management device 10 is an information processing device including a computer, and includes an information acquisition unit 11, a process determination unit 12, a storage unit 13, and a management unit 14, as shown in FIG.
The storage unit 13 includes a non-volatile storage device such as a flash memory and a ROM, and a volatile storage device such as a RAM. The information acquisition unit 11, the process determination unit 12, and the management unit 14 are realized by the CPU and software, and are configured to be able to execute the processing necessary for recording and managing the tunnel construction process and the cycle time. The management device 10 may be configured by hardware logic.

Digital signals from the power meters 1a to 1e shown in FIG. 1 are input to the information acquisition unit 11 at any time. In the present embodiment, the information acquisition unit 11 acquires ON / OFF information of the electricity usage state as electricity usage information from each of the power meters 1a to 1e.
The process determination unit 12 analyzes the electricity usage information acquired in time series by the information acquisition unit 11, determines the corresponding tunnel construction process, and transmits it to the management unit 14. The storage unit 13 stores information on the tunnel construction process determined by the information acquisition unit 11 in chronological order and stores cycle time information.

The management unit 14 stores the information of the tunnel construction process and the information of the cycle time determined by the process determination unit 12 in the storage unit 13, and based on the information stored in the storage unit 13, the management unit 14 of the tunnel construction process.

Further, the management unit 14 outputs information on the tunnel construction process and cycle time, and information on progress status or scheduling management based on the information to a plurality of information processing terminal devices 30A, 30B, 30C, etc. shown in FIG. do. As the information processing terminal devices 30A, 30B, and 30C, devices such as smartphones, tablets, and personal computers can be appropriately used.

Can be sent to. Further, it may be configured so that it can be connected to a communication network.
Next, the cycle time management process executed by the management device 10 of the first embodiment will be described with reference to FIG.

As shown in the figure, when the cycle time management process is executed by the management device 10 of the first embodiment, first, the process proceeds to step S1 and a series of cycle time recording processes are executed. The cycle time recording process is an interrupt process to the main routine, and in the main routine, the progress status management process in step S2 and the scheduling management process in step S3 are substantially simultaneously performed in parallel with the cycle time recording process. Will be executed. In step S4, the presence or absence of processing continuation information is monitored. For example, when the end command input from the operator is confirmed (No), the process ends, and when not (Yes), the process returns to step S1 and continues the process. do.

Next, the cycle time recording process of step S1 executed by the management device 10 will be described with reference to FIG.
As shown in the figure, when the cycle time recording process is executed by the management device 10 of the first embodiment, first, the process proceeds to step S11, and ON / OFF of the power meters 1a to 1e shown in FIG. Monitor the situation. In the following step S12, it is determined whether or not there is an "ON" wattmeter, and if there is no "ON" wattmeter (No), the process is returned to step S11, and if there is an "ON" wattmeter (Yes). ), The process proceeds to step S13. In step S13, since the equipment or equipment group corresponding to the “ON” power meter is operating, it is estimated that the tunnel construction process in which the equipment or equipment group is used is the process during the construction work.

In the following step S14, it is determined whether or not the process requires additional information in order to certify the process during the construction work, and if the additional information is required, the process proceeds to step S15 (Yes), otherwise. (No) The process proceeds to step S16. Here, this determination is made with reference to the relationship between the equipment or equipment group corresponding to the "ON" power meter and the time-series process sequence information that is inevitably determined from the tunnel construction work.

That is, for example, in FIG. 1, two construction processes correspond to each of the devices 3A and 3F, and one construction process corresponds to the other devices 3B to 3E. Therefore, when there are a plurality of steps that use the same device or device group in the plurality of steps, the same device or device group is used only from the ON / OFF status of each wattmeter 1a to 1e. It is not possible to determine which of the plurality of steps is the step during the construction work. Therefore, this is determined by referring to the device or device group corresponding to the "ON" power meter and the information on the process order in the time series (described later).

In step S15, as additional information, information on the time-series process sequence is referred to, and it is determined which of the plurality of processes using the same device or device group is the process during the construction work. Then, the process proceeds to step S15. In step S15, the process determined in step S13 or determined in step S15 is determined as the process being constructed is "started", and this is recorded together with the time-series information.

In the following step S17, it is monitored whether or not the power meter corresponding to the process during the construction work is "OFF", and if it is "OFF", the process proceeds to step S18, otherwise it is a step until it becomes "OFF". Wait at S17. In step S18, it is assumed that the process during the construction work is "completed", and this is recorded together with the time-series information.
In the following step S19, it is determined whether or not there is a remaining next tunnel construction step among the plurality of steps constituting the cycle time, and if there is a next tunnel construction step, the process is returned to step S11, and the next step is performed. If there is no tunnel construction process, it is assumed that one cycle time has been completed by moving to step S20, and a plurality of construction processes recorded in order up to that point are certified as one cycle time, and this is recorded and processing is performed, for example, cycle time. Return to the main routine of management processing.

Next, the operation and operation / effect of the cycle time management process (including the cycle time recording process) executed by the management device 10 will be described together with the tunnel construction work.
As mentioned above, in the construction work of the tunnel, first, a hole is made in the ground (drilling process), an explosive is charged in the hole and blasted (blasting process), and then slipping is performed. (Sliding process). Next, concrete is first sprayed onto the peripheral wall surface of the blasted digging part, then a support work is built, and then a secondary spraying is performed to complete one cycle (the digging part closing process).

The management device 10 always executes the cycle time management process during the tunnel construction work, and monitors the ON / OFF status of the power meters 1a to 1e corresponding to each tunnel construction process (step S11 above). Here, in the first embodiment, among the plurality of tunnel construction processes, first, in the drilling process, the drill jumbo is associated with the equipment 3A in the first construction process, for example.

In the drilling process, the drill jumbo stops after reaching a predetermined position by driving the engine, and the power is turned on after the outriggers are stretched (start of the drilling process). This activates a hydraulic motor to drive the boom and mangauge. Then, when the drill jumbo finishes the drilling work, it descends backward from the face for blasting evacuation. At that time, the corresponding power supply is turned off (completion of the drilling process), and then the vehicle is driven by the engine. Therefore, the management device 10 determines the start time and the completion time of the drilling process from the ON / OFF information acquired from the power meter 1a attached to the distribution board 2V corresponding to the device 3A, and determines this. Can be recorded.

More specifically, the management device 10 determines that the power meter 1a is "ON" by monitoring the ON / OFF status (step S12 above). At this time, in the management device 10, since the device 3A corresponding to the power meter 1a is a drill jumbo, the process during the construction work is either the first construction step or the fifth construction step (see FIG. 1). ..
Therefore, the management device 10 determines that the additional information is necessary (Yes in step S14), and refers to the flag at the start of the cycle time recording process as the additional information in step S15. As a result, it can be seen from the flag at the start of the cycle time recording process that the management device 10 is the first step in one cycle time during the construction work. Therefore, the management device 10 determines that the "drilling process" has been started based on the fact that the power meter 1a is "ON" and the flag at the start of the cycle time recording process, and determines that the "drilling process" has started, and determines this in chronological order. Record with the information (step S16 above).

Further, the management device 10 monitors the state in which the power meter 1a is changed from “ON” to “OFF” (step S17 above), and when the power meter 1a is changed to “OFF”, the cycle time recording process is started. From the flag, it is determined that the "drilling process" has been completed, and this is recorded together with the time-series information (step S18 above). Since this is the first step in one cycle time (Yes in step S19), the ON / OFF status of the power meters 1a to 1e is continuously monitored (step S11 above). Since the same processing steps are also applied to the certification of the subsequent processes during other construction work, detailed description thereof will be omitted as appropriate thereafter.

Next, in the blasting process, for example, as the device groups 3B and 3C in the second construction process, a communication device for sounding a siren and a face lighting device are associated with each other. That is, before the blasting, the electricity of the face lighting device is turned off, and the power of the communication device for sounding the siren is turned on. Then, as shown in FIG. 1, in the second construction step, since there is no other construction step corresponding to the device groups 3B and 3C, it is not necessary to refer to the additional information (No in step S14). Therefore, the management device 10 of the first embodiment has the pre-blasting face illumination in the blasting process from the ON / OFF information acquired from the power meter 1b attached to the distribution board 2W corresponding to the device groups 3B and 3C. It is possible to determine and record the turn-off time, the time before blasting, and the time of blasting.

Next, in the slip-out process, for example, the dust collector and the blower are associated with each other as the equipment groups 3D and 3E in the third construction process. That is, since dust flies after blasting, the dust collector automatically operates according to the detected value of the dust sensor, and the blower is turned on after a time lag. As shown in FIG. 1, the third construction step does not have other construction steps corresponding to the device groups 3D and 3E, so that it is not necessary to refer to the additional information (No in step S14).

Therefore, the management device 10 has ON / OFF information acquired from the power meter 1c attached to the distribution board 2X corresponding to the device 3D, and the power meter 1d attached to the distribution board 2Y corresponding to the device 3E. From the ON / OFF information obtained from the above, the dust collector operation start time and the blower operation start time can be determined and recorded as information corresponding to the start time of the slip-out process.

Next, in the primary spraying step of the bare digging portion closing step, the spraying robot is associated with, for example, the equipment 3F in the fourth construction step. That is, where the primary spraying work is performed after the slip-out process, the spraying robot stops after advancing to a predetermined position by driving its own engine, and then turns on the compressor to start the primary spraying work. .. Then, after the primary spraying work is completed, the power of the compressor is turned off. Here, as shown in FIG. 1, the fourth construction step includes the sixth construction step as the corresponding other step, so that additional information is referred to (Yes in step S14). Therefore, the management device 10 starts the primary spraying process from the ON / OFF information acquired from the power meter 1e attached to the distribution board 2Z corresponding to the device 3F and the flag at the start of the cycle time recording process. The start time and completion time can be determined and recorded.

Next, in the process of closing the bare digging part, in the process of building the support work (or the process of placing the lock bolt), as the fifth construction process, the drill jumbo of the equipment 3A in the above-mentioned first construction process is used. It is associated. That is, after the completion of the primary spraying, the support construction building process (or the lock bolt driving process) is performed by the drill jumbo.
In the support work construction work (or lock bolt driving work), the drill jumbo stops after advancing to a predetermined position by the drive of the engine, and the power is turned on after the outriggers are stretched, as in the case of drilling. This activates a hydraulic motor to drive the boom and mangauge.

Therefore, the management device 10 is installed before the ON / OFF information acquired from the power meter 1a attached to the distribution board 2V corresponding to the device 3A and the flag at the start of the cycle time recording process. Since the information of the spraying process stored as the process information is the information of the completion time of the primary spraying process (Yes in step S14 above), the start time and the completion time of the support construction construction process (or the lock bolt placing process) (Step S15), and this can be recorded (step S16).
In some cases, a spraying robot that can be built in support work is used, but when using this, the corresponding distribution board and the power meter attached to it are used, and the electric capacity is used as judgment information. It can be distinguished from the spraying work by comparing the difference in the size of.

Finally, in the secondary spraying process of the digging part closing process, the spraying robot is associated with the equipment 3F in the sixth construction process as in the primary spraying process (fourth construction process). .. In the secondary spraying process, the management device 10 receives the ON / OFF information of the power meter 1e attached to the distribution board 2Z corresponding to the device 3F and the flag at the start of the cycle time recording process. Since the spraying process information stored as the construction process information is the information on the completion time of the primary spraying process (Yes in step S14 above), the start time and completion time of the secondary spraying process are determined (step S15 above). , This can be recorded (step S16 above).

As described above, according to the management device 10 of the first embodiment, it is possible to record the construction steps (first to sixth construction steps) of the key points in the tunnel construction at any time. Then, the management device 10 can determine that the construction process of the key points is one cycle time from the start of the drilling process to the completion of the secondary spraying process (step S19), and can record this (step S19). Step S20).

Therefore, according to the management device 10, the tunnel construction process and the cycle time based on the tunnel construction process can be easily recorded. As a result, the operation information of the equipment corresponding to the tunnel construction process, cycle time, etc. in the plurality of equipments 3A to 3F is output to the plurality of information terminal devices 30A, 30B, 30C, etc., so that the entire tunnel construction site It can be used to improve workability and reduce energy consumption.

Further, as described above, in the cycle time management process, the management device 10 executes the progress status management process and the scheduling management process in parallel with the cycle time recording process. , Various management can be performed based on the tunnel construction process and the cycle time based on this. Therefore, the work efficiency can be further improved.

Specifically, in the progress status management process and the scheduling management process, for example, the tunnel construction process corresponding to the predetermined time can be found by comparing the reference cycle time with the current cycle time. Therefore, on the contrary, since it is not obtained from the electricity usage information corresponding to the tunnel construction process corresponding to the predetermined time, it is judged that "the △△ equipment is out of order because it should be XX work", and this is described above. It can be output to the information processing terminal devices 30A, 30B, 30C and the like.

In addition, in the progress management process and scheduling management process, judging from the cycle time recorded so far, it is judged that "○○ work is likely to be completed in 10 minutes", and the next tunnel construction is automatically performed. By outputting the instruction for preparation of the process (for example, the start of mixing concrete) to the information processing terminal devices 30A, 30B, 30C and the like, the construction can be efficiently proceeded. In addition, in anticipation of construction work that consumes a large amount of power and cannot be carried out in duplicate, instructions such as "Because XX work is being carried out on the face, □□ work is prohibited" are output to the above information processing terminal devices 30A, 30B, 30C, etc. By doing so, it is possible to prevent unexpected troubles.

In this way, according to the management device 10, since the progress status management process and the scheduling management process are executed, the timing of electricity usage and the change over time are constantly monitored, and the failure time and failure of the device are constantly monitored from the information. I understand the cause. In addition, in tunnel construction, the faulty part can be found quickly, so that the productivity can be improved. In particular, the more knowledge and experience related to tunnel construction, the more various things can be understood from the recorded data, which can be used for better tunnel construction management.

[Second Embodiment]
Next, a second embodiment of the cycle time management device according to the present invention will be described. The cycle time management device of the second embodiment is an example of determining the corresponding device or device group from the waveform of the electric energy obtained from the electricity usage information, and determining the tunnel construction process. FIG. 5 shows the overall configuration of the second embodiment.

In the second embodiment, the equipment used for tunnel construction is used as in the first embodiment except for the content of information processing based on the electricity usage information, and the above-mentioned construction process is performed in the same manner as in the first embodiment. The cycle time similar to that of the first embodiment is repeated, but in order to facilitate understanding, the number of devices is set to 3A to 3C ... 3F, and the correspondence with the specific devices used for tunnel construction and the concrete The explanation of the correspondence with the specific construction contents will be omitted.

As shown in the figure, in the second embodiment, the power meters 1a and 1b are attached to the distribution boards 2X and 2Y, but the steps are applied to the plurality of devices 3A to 3C ... 3F. It is different from the first embodiment in that it is not arranged so as to correspond to. Further, the management device 10 of the second embodiment is different from the first embodiment in that the outputs of the wattmeters 1a and 1b are not individually monitored, and the electricity usage information of the entire system is monitored.

Here, the inventor of the present application indicates that the waveform of the electric energy shows a unique waveform pattern of the equipment or the equipment group corresponding to each tunnel construction process, and by detecting this unique waveform pattern by the pattern recognition method, each of them We focused on the fact that process information corresponding to the tunnel construction process can be obtained.
That is, as shown in FIG. 5, an image of a unique waveform pattern corresponding to each tunnel construction process is added. For example, in the case of the device 3A, the waveform pattern of the code Ha shown in the figure can be obtained during its operation. In the case of the device groups 3B and 3C, the waveform patterns of the symbols Hb and c shown in the figure can be obtained during these operations. Further, for example, in the case of the device 3F, the waveform pattern of the reference numeral Hd shown in the figure can be obtained during its operation.

Therefore, in the cycle time management device of the second embodiment, these unique waveform patterns are designated as "reference waveforms", and the reference waveform and the waveform of the electric energy acquired in time series are compared by a pattern recognition method. It is presumed that the device or device group associated with the reference waveform that most closely resembles the waveform of the electric energy acquired in time series is used, and the process of using the linked device or device group is the corresponding tunnel. It is determined that it is a construction process and is memorized.

Specifically, as shown in FIG. 6, when the cycle time recording process is executed by the management device 10 of the second embodiment, first, the process proceeds to step S21, and the electric energy amount is used as the electricity usage information of the entire system. Get time series information.
An image of time-series information of the acquired electric energy is shown in FIG. In the example shown in the figure, when the devices 3A to 3F ... Device groups 3B and 3C are operated in this order from the start of the cycle time, the waveform patterns Ha1 to Hd1 ... Hb · c1 corresponding to each are operated. Is acquired together with the time series (time information in the figure). Then, when one cycle time Cy ends, the next cycle time is started, and again, in the order of device 3A to device 3F ... device group 3B, C, Ha2 to Hd2 ... Hb · c2 corresponding to each. Is acquired in chronological order.

In the following step S22, the presence or absence of the corresponding process information (that is, the corresponding tunnel construction process) is detected by comparing with the reference waveform from the waveform of the electric energy obtained from the electricity usage information acquired in time series, and the process information is obtained. If it is detected, the process proceeds to (Yes) step S23, and if not, the process returns to (No) step S21. Then, in step S23, the detected process information is recorded together with the time-series information as the corresponding tunnel construction process, and the process proceeds to step S24. In step S24, it is determined whether or not there is a next tunnel construction process during the cycle time. Then, if there is a next tunnel construction step, the process returns to step S21 (Yes), and if not, the process proceeds to step S25 (No). In step S25, the cycle time is recorded and the process is returned.

Here, in the second embodiment, as the "reference waveform", waveform patterns Ha, Hd, Hb · c, etc. may be stored in the storage unit 13 in advance, or from the power sources of a plurality of devices. The waveform pattern information set based on the power amount information acquired in time series may be used.
Now, in the second embodiment, of the plurality of devices 3A to 3D ..., from the time when the device or device group corresponding to the tunnel construction process of the Nth (where N is a natural number) starts to operate to when it ends. The electricity usage information acquired in chronological order shall be referred to as "Nth process information". Further, the waveform of the electric energy obtained from the Nth process information is called "Nth process waveform", and the waveform of the electric energy set or the waveform of the set electric energy corresponding to the Nth tunnel construction process. Is referred to as the "Nth reference waveform".

That is, in the second embodiment, when the "reference waveform" stored in the storage unit 13 in advance is used, in the example shown in FIG. 8, counting from the beginning of the cycle of the cycle time Cy (time 9:00), Of the plurality of devices 3A to 3C ... 3F, the electricity usage information acquired in chronological order from 9:00 when the device 3A corresponding to the first tunnel construction process started operation to 10:00 when it ended was ". First process information ". The waveform of the electric energy obtained corresponding to this "first process information" is the "first process waveform Ha1" in the figure, which is preset to correspond to the first tunnel construction process. The “reference waveform” is the “first reference waveform Ha” shown in FIG.

The process determination unit 12 uses the N-th reference waveform (in FIG. 5) from the waveform of the electric energy obtained from the electricity usage information acquired in time series (Ha1, Hd1, Hb · c1 ... In the example of FIG. 8). The waveforms corresponding to Ha, Hd, Hb · c ...) To be shown are detected as the Nth step waveform by the pattern recognition method. Thereby, the tunnel construction process corresponding to the Nth process information can be determined. The degree of collation (evaluation standard) at the time of comparison by pattern recognition can be expressed by a correlation coefficient or a known evaluation standard such as a convolution integral value.

Further, in the second embodiment, when the "Nth reference waveform" is set from the comparison information of the waveform patterns and the "Nth reference waveform" is used, it is set as corresponding to the Nth tunnel construction process. When the waveform of the power amount is called the "Nth reference waveform", the process determination unit 12 acquires a cyclic power amount waveform pattern from the power amount waveform obtained from the electricity usage information acquired in time series. Occasionally, the waveform pattern can be set as the Nth reference waveform corresponding to the Nth process information.

As a specific process, for example, the management device 10 executes the reference waveform setting process shown in FIG. 7 in parallel. In this process, first, the process proceeds to step S31 to acquire time-series information on the electric energy, and in the following step S32, the presence or absence of a start trigger is monitored. As the start trigger, for example, as shown in FIG. 8, a threshold value Wt is set for the reference electric energy Wk, and when a rising change of the electric energy exceeding this threshold value Wt is detected, the waveform pattern is set. It can be a start trigger.

When the start trigger is detected, the process proceeds to step S33, the reference waveform information generation process is executed, and in the subsequent step S34, the presence or absence of the end trigger is monitored. As the end trigger, for example, as shown in FIG. 8, a threshold value Wt is set for the reference electric energy Wk, and a waveform pattern is obtained when a falling change in the electric energy exceeding this threshold value Wt is detected. Can be the end trigger of.

Thereby, in the example shown in FIG. 8, the time points of 9:00 and 10:00 can be detected at the start time and the end time of the waveform pattern, respectively. In this example, since the start trigger is detected at 9:00 (step S32), the reference waveform information generation process (step S33) including the filter process is started, and the end trigger is detected at 10:00 (step S32). Step S34) and the reference waveform information generation process (step S33) are completed, and the waveform pattern obtained during that process is stored in the storage unit 13 as reference waveform information (step S35).

Then, when a plurality of cycle time information is acquired, a matching process for comparing the plurality of reference waveform information with each other is performed (step S36), and when the reference waveform information to be collated with each other is obtained, it is referred to as "reference waveform". ". In the example shown in FIG. 8, when the Nth process waveform Ha2 corresponding to the first process waveform Ha1 is obtained, the waveform pattern Ha2 is set as the Nth reference waveform Ha corresponding to the Nth process information.

Then, the presence or absence of the next reference waveform required to configure one cycle time is determined (step S37), and the above processing is performed until the reference waveforms required to certify the tunnel construction process constituting the cycle time are prepared. Will be continued. Then, once the reference waveforms required for certification of the plurality of tunnel construction processes constituting the cycle time are prepared, each tunnel construction process can be determined by comparing the time-series information with the plurality of tunnel construction processes. ..

After the reference waveform setting process is completed, in the cycle time recording process described above, the waveform corresponding to the set Nth reference waveform (for example, Ha) is obtained from the waveform of the amount of power obtained from the electricity usage information acquired in time series. By detecting as the Nth process waveform (for example, Han) by pattern matching (template matching), the Nth construction process can be determined as the tunnel construction process corresponding to the Nth process information. The waveform of the actual amount of electricity changes at any time due to various factors. Therefore, it is preferable to appropriately revise the reference waveform, such as appropriately performing the reference waveform setting process and performing the low-pass filter process so as to follow such a change with time.

Further, according to the cycle time management process of the management device 10 of the second embodiment, the determination is made by the waveform analysis of the power consumption as compared with the one which is determined from the ON / OFF information as in the first embodiment. Therefore, more detailed progress management and scheduling management can be performed.
For example, in the management device 10 of the second embodiment, in the progress status management process of step S2 and the scheduling management process of step S3 described above, the management unit 14 performs a process related to the progress status or scheduling management of the tunnel construction process. Based on the comparison result between the Nth process waveform and the Nth reference waveform during the cycle time under control, the operating state of the device or the device group corresponding to the Nth process information can be evaluated. ..

Further, in the management device 10 of the second embodiment, when the management unit 14 executes the process related to the progress status of the tunnel construction process or the scheduling management, the Nth process waveform in the cycle time being managed and the Nth process waveform in another cycle time are executed. Based on the comparison result with the N process waveform, the operating state of the device or the device group corresponding to the Nth process information in the cycle time under control can be evaluated.

Furthermore, in the management device 10 of the second embodiment, the management unit 14 sets the length of the period of the Nth process waveform in the cycle time under management when executing the process related to the progress status of the tunnel construction process or the scheduling management. Based on this, it is possible to evaluate the construction status during the cycle time by the equipment or equipment group corresponding to the Nth process information.

It goes without saying that various modifications are possible without departing from the gist of the invention.

The management device or the tunnel construction process recording device shall have various modes as long as it is substantially realized in the cycle time management system of FIG. 1 or FIG. 5 illustrated in the first to second embodiments. Can be done.

For example, in the first to second embodiments, the storage unit 13 of the management device 10 has shown an example corresponding to the “process information recording unit”, but the present invention is not limited to this, and is described in the means for solving the problem. The "process information recording unit" can correspond to any storage device constituting the cycle time management system. For example, the storage devices of the information processing terminal devices 30A, 30B, and 30C may be associated with each other. Further, for example, a cloud can be used.

The same applies to the "process determination unit". In the first to second embodiments, the process determination unit 13 of the management device 10 corresponds to the process determination unit 13, but the control device 10 is not limited to this. Without providing the process determination unit 12, the management device 10 may be provided with an information acquisition unit 11 and a management unit 14, and a "process determination unit" may be provided on the side of the information processing terminal devices 30A, 30B, and 30C.
In this case, for example, the management unit 14 outputs various information input to the information acquisition unit 11 as it is to the information processing terminal devices 30A, 30B, 30C, and causes the information processing terminal devices 30A, 30B, 30C to perform the "process". The program can be configured to execute the process corresponding to the "determination unit", return the result to the management unit 14 of the management device 10, and continue the other processing that continues based on the acquisition result. The same applies to the execution of processing related to progress status or scheduling management.
