Description

  The present invention relates to a construction machine operation status management system and a management method, and in particular, receives a machine signal including a parameter or a set value at the time of operation of a construction machine, analyzes the construction cycle based on the operation time of each construction machine, and obtains the construction cycle. The present invention relates to a construction machine operation status management system and a management method for executing at least one of extraction of work that becomes a bottleneck and prediction of future construction progress in securing a planned process from a construction cycle.

  In construction work, construction equipment plays a major role, and the operating status of construction equipment generally greatly affects the work schedule of the entire construction work. Particularly in large-scale construction, multiple construction machines proceed in parallel according to the construction schedule given their respective areas, but even if one unit breaks down or even if no breakdown occurs, for example, For example, if the vehicle hits the hard ground, the construction schedule will be later than expected, and the entire construction schedule will be delayed not only in the area in charge.

  For this reason, construction machinery must always be properly maintained to prevent failures, as well as to determine whether construction is progressing on schedule according to the planned construction schedule, even if there is no abnormality in the construction machinery. In some cases, appropriate measures need to be taken. However, in many cases, such as large-scale construction and tunnel construction, where the construction equipment operates is far from the construction supervisor, it is not easy to grasp the operation status of the construction equipment in real time. It can happen.

  Patent Literature 1 discloses a periodic report that receives information of various sensors provided in a work machine and displays an operation state of the work machine at predetermined intervals, and an emergency report that notifies the sensor output when there is an abnormality in the sensor output. A management server that creates a report and sends the report to a purchaser of a work machine or a maintenance staff of the work machine is disclosed. It is exemplified that a regular report describes data such as daily operating hours and fuel consumption.

  Patent Document 2 discloses that when the work amount is calculated based on the topography of the construction site and the like, the work plan data is created based on the work amount and the unique conditions of the work machine, and the work plan and the work plan are executed. The construction management system which outputs the construction cost of the construction is disclosed.

According to Patent Literature 1, it is possible to grasp the operating status of the work machine in detail including the presence or absence of an abnormality. However, there is no indication as to whether the construction is progressing as planned against the overall work plan.
Further, according to Patent Literature 2, it is possible to calculate a work amount from data of a sensor attached to a work machine or the like and to see a difference from the construction plan data to grasp a delay in work progress. However, even if a delay in the construction plan is recognized, it is not possible to see which work has a problem and how to recover the work.

  Therefore, while grasping the load status of the construction machine from the operation status of the construction machine, the construction cycle is analyzed, and if there is a delay in the work, how much delay is likely to be finally reached, or what work is the problem? It is necessary to realize an operation status management system that can clarify whether there is any problem and link it to the measures.

Next, a specific example of an embodiment for implementing a construction machine operation status management system according to the present invention will be described in detail with reference to the drawings.
FIG. 1 is a block diagram schematically showing an overall configuration of a construction machine operation status management system according to an embodiment of the present invention.
Referring to FIG. 1, a construction machine operation status management system 1 according to an embodiment of the present invention includes a management server 10, a construction machine terminal 20, and a user terminal 30, which are interconnected via a network 5.

  The construction machine operation status management system 1 attaches a construction machine terminal 20 that acquires and outputs a machine signal such as a parameter or a set value at the time of operation of the construction machine to each of the construction machines used at the construction site. At 10, a machine signal is received from each construction machine terminal 20, and an operation time and a load during operation are calculated based on the machine signal of each construction machine, and whether each construction machine is operating normally is determined. That is, while analyzing the soundness, accumulating the operation time and the load during operation, updating the maintenance timing of the construction machine based on the accumulated result, and transmitting the soundness and the maintenance timing to the user terminal 30 when necessary. Notification system.

  The management server 10 of the construction machine operation status management system 1 collectively displays the operation time of each construction machine based on the received machine signal, analyzes the construction cycle based on the operation time of each construction machine, and obtains the obtained construction. From the cycle, we will identify the work that will be the bottleneck in securing the planned process and predict the future construction progress.

  Further, the management server 10 acquires the current position information of each construction machine from the position detecting means for detecting the position of the construction machine, updates and manages the latest position information as the latest position information, and performs construction for the extracted bottleneck work. If a construction machine or a component for construction machinery that can be a work improvement factor or a backup by replacing or adding a machine is available, output it as work improvement information including the list or map, and construct from the list or map. When a member for a machine or a construction machine is selected, a recovery schedule in the case of improvement or backup is simulated and displayed.

  As described above, the construction machine operation status management system 1 determines whether the construction machine or the construction machine member used at the construction site is operating normally, and when an appropriate maintenance timing according to the operation status is delayed in the construction work. If a problem occurs, the user terminal must provide information such as what work is the bottleneck, and which construction machine should be used to recover the delay, and in that case, how much the work schedule can be recovered. 30 is a system that provides powerful information for construction machine operation status management to construction machine operators and maintenance staff, including a construction site operator who is a user.

  Referring to FIG. 1, the management server 10 includes a control unit 11, an input / output unit 12, a storage unit 13, a display unit 14, a construction machine information management unit 15, a maintenance information providing unit 16, a construction cycle analysis unit 17, and position information. It includes a management unit 18.

  The construction machine information management unit 15 calculates an operation time and a load for each construction machine based on the machine signal received from the construction machine terminal 20, and based on predetermined items and determination criteria, the construction machine and the construction machine members. Analyze the health of The machine signal includes outputs of various sensors attached to the construction machine, set values of an operation panel of the construction machine, and the like. The machine signal includes, for example, the time when the main power of the construction machine is turned on or off, and the time when the hydraulic pump is activated or stopped in a construction machine having a hydraulic drive unit, such as the start of the actual operation unit that contributes to the work. Includes information needed to understand operating time, such as time and end time. In addition, when the construction machine is a drill jumbo, information on a load of the construction machine such as an engine speed and a traveling distance is also included.

The construction machine information management unit 15 refers to information such as how much the actual operation unit contributing to the work has been operated while the main power was on, and whether the load at that time was within a normal range. Analyze the soundness of construction equipment and construction equipment components.
In the soundness analysis, since the items to be determined differ for each construction machine, in the embodiment, the construction machine information management unit 15 determines the predetermined items for each construction machine and the determination criteria such as the upper limit value and the lower limit value for the item. Is stored, and the results of the operation time and load calculation are analyzed for soundness based on the determination criterion table.
Regarding the operation time, in the case of a construction machine that repeats a fixed operation, a standard operation time for each operation may be set in advance, and if the operation time deviates, it may be determined that there is an abnormality in soundness. .

  When the construction machine information management unit 15 determines that there is an abnormality in the soundness of the construction machine, the construction machine information management unit 15 transmits abnormality information to notify the user terminal 30 of the user related to the construction machine that an abnormality has occurred in the soundness. Notice. The construction machine information management unit 15 judges the current situation of each construction machine including the presence or absence of such an abnormality, and in a state where the main power is off (during stop), the main power is on but the actual operation which contributes to the work is performed. The output may be divided into a state in which the unit is not operating (waiting), a state in which the actual operating unit is operating (operating), a state in which an error has occurred (error occurrence), and the like.

  The maintenance information providing unit 16 accumulates the operation time and load for each construction machine, recalculates / updates the maintenance timing based on the accumulated result, and sends the maintenance timing to the user terminal 30 periodically or in accordance with the timing of performing the maintenance. Send. For this reason, the maintenance information providing unit 16 stores the accumulated data of the operation time and the load for each construction machine, and the construction machine newly starts operation. Is calculated and updated in addition to the accumulated operating time and load data for each construction machine that has acquired and stored the calculated operating time and load.

  Regarding the load, the degree of influence on the construction machine may vary depending on the magnitude of the load. Therefore, ranks may be classified based on the magnitude of the load and accumulated data for each rank may be used. For example, in the case of the drifter torque, A to C are ranked according to the magnitude of the torque, and the cumulative time of driving in the torque range of rank A, the cumulative time of driving in the torque range of rank B, and the torque of rank C The cumulative time driven in the range may be used as additional cumulative data. By doing so, it is possible to grasp the operation status more in accordance with the actual situation.For example, maintenance timing for construction machinery that has been used under a high load condition is advanced compared to when operating with a normal load. Timing can be optimized.

  Further, in a construction machine such as a dump truck that mainly travels, a fuel consumption rate based on a traveling distance and a used fuel amount may be included as load data. In this case, the accumulated fuel consumption rate may be obtained and stored from the accumulated traveling distance and the accumulated used fuel amount, and the fuel consumption rate obtained every time fuel is replenished may be continuously stored as load accumulated data. Thereby, if the fuel consumption rate is deteriorated, the maintenance timing can be optimized, such as the maintenance timing is advanced.

  The maintenance timing of the construction machine is desirably based on the accumulated operation time and the accumulated load. However, since the operation time and the load differ from day to day, it is difficult to predetermine the date of maintenance. Accordingly, the maintenance information providing unit 16 recalculates / updates the scheduled maintenance date based on the elapsed date and the cumulative operating time of each construction machine in consideration of the daily work results and outputs the operating time. The correction of the scheduled maintenance date at this time may be performed based on the overall average operation time obtained from the elapsed date and the accumulated operation time, or based on the average operation time obtained from the latest specific period operation time. Is also good. If the overall average operation time or the average operation time is obtained, it is possible to calculate the scheduled date to reach the cumulative operation time for performing the next maintenance.

  The maintenance information providing unit 16 outputs a more accurate scheduled maintenance date taking into account the effect of the cumulative load on the scheduled maintenance date obtained from the cumulative operating time. Considering the influence of the cumulative load, for example, the loads are classified into A to C according to the magnitude of the load as in the above example, and the cumulative operation time in the rank A with the large load is determined by a predetermined coefficient. The cumulative operating time of all ranks is calculated by reducing the cumulative operating time of rank C with a small load by a predetermined coefficient and converting the cumulative operating time to the operating time when operating at standard rank B. Is used, and this value is used in place of the above-described overall average operation time or the accumulated operation time for calculating the average operation time.

  As described above, the maintenance information providing unit 16 updates the maintenance timing to an appropriate time based on the accumulated operation time and the accumulated load, and outputs the updated timing. As a result, it is possible to keep operating under a high load condition and to prevent an unexpected trouble such as a failure of the construction machine earlier than the scheduled maintenance timing.

  The construction cycle analysis unit 17 collectively displays the operation times of the respective construction machines, analyzes the construction cycle based on the operation times of the respective construction machines, and extracts a bottleneck operation from the obtained construction cycle or a future construction. At least one of the progress prediction is performed. The construction cycle refers to a series of cycles in the case of construction in which a series of fixed work is repeated to progress the entire construction.

  The operation time of the construction machine does not always correspond to the operation time of the work to which the construction machine is applied. Taking tunnel construction as an example, the main construction equipment used is a drill jumbo for drilling for blasting, a breaker for dropping stones, a wheel loader and dump truck for shedding, and concrete blowing. For drilling machines, drill jumbo is used not only for drilling and charging operations for blasting but also for drilling for installing rock bolts in rock bolt operations. On the other hand, in the sliding work, the wheel loader and the dump truck are performed in cooperation, so that a plurality of construction machines are applied to one work.

  Therefore, the construction cycle analysis unit 17 collectively displays the operation times of the construction machines, allocates the operation times of the construction machines to the respective operations of the construction cycle based on a preset construction cycle, and creates a construction cycle table. . The construction cycle table is a table displayed so that the time required for each work in the construction cycle in the construction order can be grasped.

  In a construction where the entire construction progresses by repeating a series of fixed work, depending on the contents of the construction, the standard work time, which is the standard work time for each work in the construction cycle, should be set from the conventional construction results Can be. By setting a daily start plan based on the standard work time for each work and superimposing the actual work time on the plan, it is possible to grasp the progress with respect to the work schedule from the difference between the two.

  The construction cycle analysis unit 17, based on the difference between the construction start plan and the actual operation time, if the construction cycle is prolonged and the construction is delayed, which work is causing the delay, that is, the cause of the delay Extract the work of the bottleneck that becomes. In addition, a construction progress prediction obtained by simulating the entire schedule when the construction is continued as it is based on the construction cycle is also performed. Extraction of the work that becomes a bottleneck and construction progress prediction can be selectively performed based on the selection of the user from the user terminal 30.

  When the construction cycle analysis unit 17 extracts the work that becomes the bottleneck, the position information and the status of the construction machine or the construction machine member that can be an improvement factor or a backup for the extracted work that becomes the bottleneck are listed or displayed. When a construction machine or a construction machine member that can be output as work improvement information including a map and can be an improvement factor or a backup is selected by a user, a recovery schedule when the selected construction machine or construction machine member is improved or backed up is selected. Is simulated and displayed.

  The construction cycle analysis unit 17 confirms the construction machine used for the work that becomes the bottleneck, extracts the same model or a similar model as the construction machine in use if it is a backup, and uses the same model if it is a capacity increase. When a higher-ranking model having a higher capacity than the construction machine is used as a replacement candidate, or added to a used construction machine to increase the capacity, construction machines that can be used together are extracted and output as a list.

  In one embodiment, such construction machines and members for construction machines for backup and capacity enhancement are listed in advance for construction machines or construction machine members held by the construction company, and the storage locations and maintenance status etc. The construction machine menu list is stored in association with the management server 10 as a construction machine menu list, and the construction machine menu list is referred to when a work that becomes a bottleneck is extracted. At this time, a list of construction machines or members for construction machines owned by the available construction machine rental company or maintenance company may also be obtained and added to the construction machine menu list.

  The construction machine or the construction machine member that can be an improvement factor or a backup may be displayed and output as an icon on a map centered on the construction site instead of being output as a list. In this case, the construction cycle analysis unit 17 extracts the storage location of the construction machine or the construction machine member selected from the construction machine menu list and displays the storage location on the map centering on the construction site. The icon may be associated with the detailed information of each construction machine or construction machine member, and the output map may be displayed on the user terminal 30, and when the user selects the icon, the detailed information may be displayed. This allows the user to visually determine a construction machine or a construction machine member that is near the construction site and is likely to be used for improvement or backup immediately.

  Delays in work, which is a bottleneck, may be due to defects in construction machines and construction machine components themselves, and in some cases the original performance may not be fully exhibited, and construction may be performed even though construction machines and construction machine components are normal. There are also environmental factors such as the situation on the site, for example, when approaching a harder area than originally expected. The construction cycle analysis unit 17 displays a construction machine or a construction machine member that can be an improvement factor for a work delay or a backup, depending on the state of the construction machine or the construction machine member, for improvement or backup.

  When the construction progress prediction or the simulation of the recovery schedule is performed, the construction cycle analysis unit 17 outputs the simulations side by side so as to be compared with the initial construction plan and referred to. When the construction progress prediction and the simulation of the recovery schedule are continuously performed, these results may be output in juxtaposition so as to be compared with the initial construction plan and referred to.

  The position information management unit 18 acquires the current position information of each construction machine from the position detection means provided in the construction machine or the construction machine terminal 20 and updates and manages it as the latest position information. The acquisition of the position information can determine the direction of the construction machine and the speed at which the construction machine is moving by shortening the interval. Therefore, the latest position information managed by the position information management unit 18 may include the presence / absence of movement, the direction and speed when moving, and the like, in addition to the position information of the construction machine.

The latest position information managed by the position information management unit 18 may be transferred to a storage location of the construction machine menu list stored in the management server 10 to be updated and stored. Thus, for a construction machine whose position can be detected by the position detecting means, the storage location of the construction machine menu list can always be maintained at the latest information.
The position detecting means may use GNSS (Global Positioning Satellite System) in an environment where there is no restriction on the use of radio waves. In an environment where GNSS cannot be used such as in a tunnel, a beacon or fixed base station is installed. Alternatively, a method of detecting the position information may be used.

  The latest position information managed by the position information management unit 18 may be output in association with the current status of each construction machine output by the construction machine information management unit 15. In this case, for example, the construction machine may be displayed in an appropriate position by an icon based on the latest position information on a sketch of a construction site, and may be displayed as a map by changing a color based on the current situation. Good. For example, if a map is displayed such as a green icon during operation and a red icon when an abnormality occurs, the construction personnel can grasp at a glance the current position and status of the construction machine applied to the construction site through the user terminal 30. can do. Further, the construction machine information management unit 15 may provide information such that when the user selects each icon, the detailed operation status of the construction machine is displayed.

The input / output unit 12 of the management server 10 receives an input device such as a keyboard and a mouse for directly inputting commands and data to the management server 10, receives a machine signal from the construction machine terminal 20 via the network 5, It includes communication means for providing information to the machine terminal 20 and the user terminal 30 and the like.
The storage unit 13 stores a program for controlling the management server 10 itself, and also stores related information such as a received machine signal and an operation time, a load, and a maintenance timing obtained based on the received machine signal. The construction machine menu list is also stored in the storage unit 13. The storage unit 13 is embodied by a hard disk, a semiconductor memory, or the like.

The display unit 14 displays a program for controlling the management server 10 itself as necessary, and displays various information stored in the storage unit 13 such as the operation time and load of the construction machine. The display unit 14 is embodied by a display device such as a liquid crystal display.
The control unit 11 controls the operation of the management server 10 according to the control program, and controls each component to perform the above functions.

On the other hand, the construction machine terminal 20 includes a control unit 21, an input / output unit 22, a storage unit 23, a machine signal acquisition unit 24, a machine signal accumulation unit 25, and a position information management unit 26.
The machine signal acquisition unit 24 acquires various signals such as operation state parameters of the construction machine and setting information of the control panel obtained from various sensors attached to the construction machine, and stores them as machine signals. Since the parameters of the various sensors differ depending on the construction machine, they vary depending on the construction machine.

  Since many of the various signals are detected as voltages and currents, the mechanical signal acquisition unit 24 stores the detected various signals together with the elapsed time. Depending on the type of construction machine, not only the type of sensor but also the number of sensors may be different. If there are a plurality of sensors, the machine signal acquisition unit 24 sets a time axis as a reference according to the time at which various signals are received. Above, the signals from the plurality of sensors are stored in correspondence with each other as mechanical signals.

  When the number of sensors is small or the interval of machine signal acquisition is wide and the capacity of the signal is small, the machine signal acquisition unit 24 sends the stored machine signal to the management server 10 via the input / output unit 22 and the network 5. Send to

  When the capacity of the machine signal stored in the machine signal acquisition unit 24 is large, the machine signal integration unit 25 aggregates the machine signal in a predetermined time unit and converts the machine signal into batch data. The signal is transmitted to the management server 10 via the input / output unit 22 and the network 5. Such batching can reduce the communication load.

  The position information management unit 26 acquires the current position information from the position detection unit of the construction machine, and stores the current position information in association with the acquired time. By associating the position information with the time axis serving as a reference for managing the machine signal, it is possible to associate the machine signal with the position information. Thereby, the machine signal acquisition unit 24 or the machine signal accumulation unit 25 may add the position information corresponding to the machine signal output to the management server 10 and transmit the same.

  The construction machine position detecting means includes the GNSS or the like as described above and outputs the position of the construction machine to which the position information detecting means is attached. The position detecting means is independent of the construction machine terminal 20 and the construction machine terminal. The position information management unit 26 may be provided with a position detection unit. In the case where the position detecting means is a device which is attached to the construction machine independently of the construction machine terminal 20, a communication means for transmitting the detected position information to the construction machine terminal 20 or the management server 10 is provided.

  The input / output unit 22 of the construction machine terminal 20 has an input terminal for inputting various signals such as various sensors of the construction machine and setting information of the control panel, and a communication unit for transmitting a machine signal to the management server 10. Including. When there are a plurality of sensors, a plurality of input terminals are provided accordingly. Outputs from the various sensors and the control panel may be input through wiring, and information exchange between the various sensors and the construction machine terminal 20 may be performed by wireless communication such as short-range wireless communication.

The network 5 is a wide area network such as a mobile phone communication network or the Internet.

FIG. 2 is a diagram showing an example of display data of the operation time totals of the construction machines and the accompanying maintenance schedule output from the management server according to the embodiment of the present invention.
Referring to FIG. 2, the display data 200 of the total operation time of each construction machine includes a construction machine column 210 indicating the type of construction machine, a date column 220 indicating a date of interest, an operation time column 230, and a maintenance schedule column 240. Including.

  The display data 200 in FIG. 2 is an example of tunnel construction, and the construction machine section 210 exemplifies a drill jumbo, a breaker, a wheel loader, a dump truck, and a spraying machine. In the date column 220, the time every two hours is indicated by an auxiliary scale, and the operation time of each construction machine obtained by the management server 10 based on the machine signal received from the construction machine terminal 20 corresponds in the form of a bar graph 250. Displayed during the time zone.

  In one embodiment, based on a construction start plan, an initial start plan, that is, a time zone in which each device is to be operated is displayed in the form of a dashed bar graph 260 in a superimposed manner. By displaying the operation times of the respective construction machines in an integrated manner, it is possible to check at a glance whether or not the respective construction machines have been operated as planned. In the example of FIG. 2, the work of the breaker, which was supposed to be completed at 14:00, was not completed as planned but was extended by about one hour, and the work by the wheel loader and the dump truck was also extended accordingly. It indicates that the work was delayed, and that the work scheduled for this day could not be performed.

  The operation time column 230 displays the operation time of the construction machine performed today, that is, the date shown in the date column 220, and the cumulative operation time of operation up to and including today. The cumulative operation time is used to calculate the scheduled maintenance date. However, as described above, the scheduled maintenance date is adjusted according to the load at the time of operation of the construction machine. Therefore, the cumulative operation time displayed in the operation time column 230 is the standard load. The converted operating time may be a cumulative value.

In the maintenance schedule column 240, the maintenance schedule obtained from the cumulative operation time and the cumulative load is displayed in two items, namely, a scheduled maintenance date for mainly performing maintenance and a scheduled replacement date for performing component replacement.
The display data 200 is merely an example, and it goes without saying that the configuration of the table and the contents of the included data are not limited thereto.

FIG. 3 is a diagram illustrating an example of display data of a construction cycle analysis result based on the operation time of each construction machine output from the management server according to the embodiment of the present invention.
Referring to FIG. 3, a construction cycle table 300, which is display data of construction cycle analysis results, is obtained by calculating time in units of work based on the operation status of each construction machine shown in FIG. A column 320 and an operation time column 330 are included.

The work column 310 displays the name of the work to which each construction machine shown in the construction machine column 210 of FIG. 2 is applied, and specifically, a drilling and charging operation corresponding to a drill jumbo and a kosoku work corresponding to a breaker. , A sliding operation corresponding to the wheel loader and the dump truck, a spraying operation corresponding to the spraying machine, and a lock bolt operation are displayed.
In the date column 320, the time zone in which each operation was performed is displayed in the form of a bar graph 350. Further, similarly to the display data 200, the work time zone corresponding to the initial start of construction is displayed in the form of a dashed bar graph 360.

The operation time column 330 displays the operation time of each operation performed today and the average operation time of the operation when a standard operation is performed based on the past results. The advance construction plan is set based on this average operation time, and it can be read that a problem has occurred if there is a large difference between today's operation time and the average operation time.
The management server 10 extracts a work that becomes a bottleneck in the construction cycle from the result of the construction cycle analysis as shown in the construction cycle table 300. The extraction of the work that becomes a bottleneck may be automatically performed following the execution of the construction cycle analysis, or may be performed by a user request from the user terminal 30.

  From FIG. 3, since the difference between the today's operation time and the average operation time is the largest in the slip-off work, the work that becomes a bottleneck may be the slip-out work. As described above, the work having the largest difference between today's operation time and the average operation time may be extracted as the work that becomes the bottleneck, but the construction cycle table 300 in FIG. 3 is as described in FIG. FIG. 9 shows data reflecting the result that the break-out operation by the breaker was delayed and the slip-out time was extended by the influence of the delay. Therefore, in the embodiment, the management server 10 extracts the confusing work that caused the delay as the work that becomes the bottleneck. As described above, in the embodiment, the work that causes the delay first among the continuous works is extracted as the work that becomes the bottleneck.

  In another embodiment, if successive work delays occur, if the delay time of the later work exceeds twice the delay time of the first work, the later work is extracted as work that becomes a bottleneck. I do. For example, if a delay of one hour occurs in the first work and a delay of two and a half hours occurs in the next work, one hour of the delay of the next work is considered to be a delay due to the influence of the first work, and Is considered to be a delay caused by the next work, and as a result, it can be determined that the delay of the next work affects the overall delay.

  In still another embodiment, all the work in which a delay exceeding a preset threshold has occurred is extracted as work that becomes a bottleneck. For example, if a delay of one hour and one and a half hours occurs due to the previous work among the continuous works as described above, if only the later work is extracted as the work that becomes a bottleneck, the earlier work is extracted. This is because a one-hour delay in the work may be overlooked.

FIG. 4 is a diagram illustrating an example of display data of a list of a list of works to be improved and a work that becomes a bottleneck output from the management server according to the embodiment of the present invention.
FIG. 4 is an example of display data relating to a rough work extracted as a work that becomes a bottleneck in the display data of FIG. 3. Referring to FIG. 4, the display data 400 of the work that becomes the bottleneck is the work data that becomes the bottleneck. , A construction machine column 420 indicating construction machines or members for construction machines applied to the work that becomes a bottleneck, an operation time column 430 indicating the current operation time and the average operation time, and an improvement or backup And a corresponding list column 440 indicating construction machines or construction machine members to be used.

  The Kosoku in the bottleneck work column 410 indicates that the work that is the bottleneck of the delay in the current construction is Kosoku work, and the breaker A001-3 in the construction machine column 420 is the construction machine currently applied to Kosoku work. The operating time column 430 indicates that the current operating time is 3.8 hours and 0.8 hours longer than the average operating time of 3 hours.

  In the correspondence list column 440, a classification is made as to whether this delay is to be backed up with the same performance as the applied construction machine, to be replaced with a higher-performance construction machine, or to be added to the applied construction machine. Along with the (segment column 441), construction machines or construction machine members (construction machine / member columns 442) that can be applied correspondingly, the current positions of the respective construction machines or construction machine members (position information columns 443). , And the status (status column 444) are shown in a list format.

For example, if the condition of the breaker A001-3 is bad and a delay is occurring, the same type of breaker A001-2 that can be used as a backup or the unit 5 will operate at its original capacity if it is applied, and further delay will occur. It is possible to take measures to prevent this. In the case where a delay from the start of construction starts due to insufficient capacity of the breaker A001-3, the capacity can be increased by replacing the breaker B021-1 with a higher capacity, the breaker C008-4, or the like. In addition to the breaker A001-3, the capacity can be increased by adding a breaker A001-2 or a breaker B021-1.

  Regarding the position information, for the construction machine or the construction machine member having the position detecting means, the management server 10 can grasp the latest position by the signal from the position detecting means. By updating and managing the information, it can be used as current position information. Also, regarding the construction machine and the construction machine member including the construction machine terminal 20, the management server 10 can grasp the state of the construction machine and the construction machine member by the machine signal received from the construction machine terminal 20. The grasped status of the construction machine can be used for the correspondence list column 440.

  With respect to the construction machine or the construction machine member that does not include the position detection unit or the construction machine terminal 20, the construction machine operator or maintenance person may appropriately input the information from the user terminal 30 or the like and provide the management server 10. . In one embodiment, a construction machine operator or maintenance person periodically obtains information on the location and status of construction machines and construction machine members owned by related construction machine and construction machine member manufacturers and rental companies. Then, by inputting the information from the user terminal 30 or the like and providing it to the management server 10, the number of menus displayed in the construction machine column 420 is increased and the possibility of correspondence is expanded.

  In addition, as shown in the lower left of FIG. 4, the display data 400 of the work that becomes a bottleneck is provided with radio buttons for selecting a malfunction of the construction machine or a lack of the capacity of the construction machine when a cause of the work delay is assumed. Alternatively, when the user selects, only the candidates corresponding to the selected item may be displayed in the correspondence list column 440.

  Each construction machine or construction machine member in the construction machine / member column 442 is displayed in a selectable manner on the screen of the user terminal 30. For example, when the user double-clicks with a mouse or the like, the selected construction machine or construction machine member is displayed. The information of the members is transmitted to the management server 10, and the management server 10 simulates a recovery schedule when the selected construction machine or the member for the construction machine is applied, and transmits the simulated schedule so as to be displayed on the user terminal 30.

  The correspondence list column 440 shown in FIG. 4 is a case where the work improvement information is output as a list, but the construction machine or the construction machine member that can be an improvement factor or a backup is displayed as an icon on a map centering on the construction site. May be output. In this case, when the user double-clicks the icon with a mouse or the like, information on the selected construction machine or construction machine member is transmitted to the management server 10, and the management is performed in the same manner as in the case of output as the above list. The server 10 simulates the recovery schedule and sends it to the user terminal 30 for display.

FIG. 5 is a diagram illustrating a simulation result of the recovery schedule output from the management server according to the embodiment of the present invention.
Referring to FIG. 5, the simulation result 500 includes an initial construction plan 510, a construction progress prediction 520, and a recovery schedule 530. In the example of FIG. 5, with respect to the initial construction plan 510, the construction progress prediction 520 when the construction is continued as it is with the current construction delayed and the recovery schedule 530 when the countermeasures against the delay are obtained are both obtained. In this case, when only one of them is performed, the initial construction plan 510 and the construction progress prediction 520 or the initial construction plan 510 and the recovery schedule 530 are displayed side by side.

  The recovery schedule 530 in FIG. 5 shows the recovery schedule when the breaker C008-4 is selected as the replacement construction machine in FIG. Although the current breaker A001-3 has a delay of about one month from the construction progress forecast 520, the construction is completed one week ahead of the initial construction plan 510 by replacing the breaker with a high-capacity type. You can read.

In addition, replacing the breaker with a high-capacity type incurs additional costs, such as transportation and rental costs, which are not included in the initial construction plan. Also, if the construction period is changed, the construction costs such as labor costs will be changed accordingly.
In one embodiment, the management server 10 combines the basic cost such as the labor cost registered in advance, the cost associated with the operation of each construction machine, the transportation cost, and the like for the construction cost, and reduces the construction cost when the backup and the improvement are performed. It is configured to calculate the change estimate and display it together with the recovery schedule 530.

  As described above, when the current construction delay occurs, the user such as a construction worker can easily determine how much delay will occur with respect to the initial construction plan 510 by the construction progress prediction 520 if the current operation results are maintained. The recovery schedule 530 is confirmed by selecting and simulating construction machines or construction machine members effective for recovery of the construction schedule from the display data 400 of the work that becomes the bottleneck shown in FIG. 4. The appropriate countermeasure can be selected. At this time, by additionally displaying the cost according to the recovery schedule 530 as described above, the user can more comprehensively select a countermeasure.

FIG. 6 is a diagram illustrating an example in which the operation status of the construction machine according to the embodiment of the present invention is displayed on a map.
FIG. 6 shows one display form of data transmitted from the management server 10 to the user terminal 30. Taking tunnel construction as an example, each construction transmitted from the construction machine terminal 20 to a construction machine applied to tunnel construction. A display example is shown in which the position and the operation status of each construction machine obtained from the machine signal of the machine and the position information of each construction machine transmitted from the position detection means are displayed at a glance.

  Referring to FIG. 6, a construction site map 600 displays a tunnel 610 under construction and a drill jumbo 620, a breaker 630, and a wheel loader 640 applied to the tunnel construction as a construction site map. The tunnel 610 shows a state in which the construction has progressed from the wellhead 611 to the face 612.

  Each construction machine is displayed as an icon, and is displayed at a corresponding position on the map corresponding to the position of each construction machine obtained from the position information. In the case of moving, a moving display 631 of a triangle indicating the moving direction indicates that the moving is in the direction of the moving display 631. The moving speed may be displayed by changing the number of the moving displays 631 of the triangle. Further, the icons may be displayed in different colors depending on the operation status of each construction machine such as operating, moving, adjusting, and stopping.

  Further, when each icon is selected by the user at the user terminal 30, the detailed status of the construction machine, for example, specifications such as processing capacity, and data such as current parameters such as the current oil pressure and load during operation are displayed. Is also good. Alternatively, a live camera may be installed at the construction site, and when the icon is selected, the detailed status of the construction machine and the live video may be selectively displayed on the user terminal 30.

  Further, the management server 10 classifies and displays which construction is currently being performed or the current construction progress of the construction site in accordance with the operation status of the construction machine operating at the construction site. That is, in the example of FIG. 6, since the drill jumbo 620 is drilling toward the face 612, a predetermined area in which the drill jumbo 620 operates is displayed as the drilling charge area 616. Further, for example, in a time zone before the operation of the drill jumbo 620, a portion from the wellhead 611 to a portion where the sprayer has sprayed the concrete is displayed as the lining concrete area 615 on the construction site map 600. In such a divided display, the construction cycle and the construction machine applied to each work are stored in advance in association with each other, and the area range and the division displayed according to the operating position and the operation state of the construction machine are associated with each other. It can be realized by saving the data.

  As described above, the management server 10 outputs the information such as the machine signal and the position information of each construction machine so that the entire situation of the construction site can be grasped at a glance. Be able to make accurate decisions and instructions. If the construction site map 600 is displayed on a large-sized display or the like, the entire operation status is shared by the workers at the construction site, and for example, the next operation can be set up at an appropriate timing.

FIG. 7 is a flowchart illustrating a construction machine operation status management method according to an embodiment of the present invention.
Referring to FIG. 7, the construction machine terminal 20 attached to each construction machine acquires a machine signal from the construction machine and outputs it to the management server 10 in step S100. Each construction machine terminal 20 includes a communication unit, and individually outputs a machine signal to the management server 10 via a communication line such as a mobile communication line or the Internet. In a case where the number of the construction machine terminals 20 is large and the communication line is congested, in one embodiment, a construction terminal for temporarily integrating the output from each construction machine terminal 20 is further provided at the construction site, and the construction terminal is provided. The collected machine signals and position information are collectively transmitted to the management server 10.

  When the construction machine or the construction machine terminal 20 is provided with the position detecting means, the position of the construction machine is detected by the position detecting means simultaneously with or before and after the construction machine terminal 20 acquires the machine signal from the construction machine, When the terminal 20 outputs the acquired machine signal to the management server 10, the position information of the construction machine is also transmitted.

The management server 10 that has received the machine signal stores the machine signal received in step S110, calculates the operating time and the operating load of the construction machine based on the received machine signal, and analyzes the soundness thereof.
Next, in step S120, the management server 10 accumulates the operation time and load for each construction machine, recalculates and updates the maintenance timing based on the accumulated result, and transmits the corrected maintenance timing to the user terminal 30. The transmission of the maintenance timing may be performed periodically, or may be transmitted at a timing that requires maintenance.

  The management server 10 collectively displays the operation times of the construction machines, and analyzes the construction cycle based on a preset construction cycle (step S130). The result of calculating the construction cycle by the analysis of the construction cycle is transmitted to the user terminal 30, and displayed so that it is easy to grasp which work was performed at which time zone and whether the work was performed as originally planned. At this time, if the analysis result of the construction cycle is not particularly delayed, an end button for terminating the analysis process may be displayed on the user terminal 30 if the delay has not occurred, and the analysis process may be terminated by the user's selection. Is displayed, the user terminal 30 displays a selection button on whether to extract the work that will be the bottleneck for the delay or to perform the future construction progress prediction when continuing the current operation status. Wait for the user to make a selection.

  It is determined whether the result selected by the user is the extraction of the work that becomes the bottleneck (step S140). If the extraction of the work that becomes the bottleneck is selected, the management server 10 extracts the work that becomes the bottleneck, Work improvement information including a construction machine or construction machine member that can be an improvement or a backup, which is information for improving the work, and a list or map of the extracted construction machine or construction machine member position information and its status. And transmits it to the user terminal 30 (step S150). At this time, the position information received by the management server 10 together with the machine signal is used.

When the user selects a construction machine or a construction machine member to be improved or backed up from the work improvement information in step S160, the management server 10 recovers the construction when the selected construction machine or construction machine member is applied. The schedule is simulated and transmitted to be displayed on the user terminal 30 (step S170).
If the result selected by the user in step S140 is the future construction progress prediction, the management server 10 executes the future construction progress prediction in step S155, and compares the future construction progress prediction with the initial construction plan. It is transmitted to the user terminal 30 so that it is displayed together with the display as possible.
