Description

  The present invention relates to a construction management system for a civil engineering work site where loading and transporting of earth and sand is performed using a loading machine and a transporting machine.

  Conventionally, various systems for optimizing a construction plan and construction management of a construction site have been proposed. As an example, a payload meter that measures the weight of a radio terminal or GPS using a GPS to detect the position of a heavy machine such as a loading machine or a transporting machine that is used at a civil engineering construction site where earth and sand are loaded and transported. A management system that enables the base station to acquire the position information and payload data from these heavy equipment and to grasp the status of work at the construction site based on the position information and payload data at the site office It has been proposed (see, for example, Patent Document 1).

  In addition, in the management system described in Patent Document 1, each heavy machine is provided with an IC card writing device, and the work start time and end time are written on the IC card. The IC card reader is provided to read the data on the IC card, and the data is displayed on the monitor as the heavy equipment operation data, or is used for formulating an enforcement plan. In addition, heavy equipment cycle times such as loading, transporting, unloading, and moving to loading places are measured and analyzed, and heavy equipment operation patterns are planned for the purpose of shortening the cycle time.

  On the other hand, in the work site where this product is transported from the place where the product of crushed stone is crushed, vehicles such as dump trucks are used for this transportation, and in order to load products from the product place into this vehicle, hydraulic A loading machine such as an excavator is used, and a system that notifies the loading machine of a vehicle loaded with a product by the loading machine is also proposed (for example, Patent Document 2). reference).

  In the system described in Patent Document 2, each vehicle is equipped with a wireless tag, and a receiver is installed near the product storage area. Whenever the vehicle passes this wireless device, the wireless device is The tag ID is received from the radio tag of the vehicle. Based on the reception result, this radio unit is close to the loading machine that loads the product in the product storage area. When detected, approach information indicating that the vehicle is approaching the loading machine is generated and transmitted to the loading machine. Thus, in the loading machine, when the vehicle on which the product is loaded is approaching, this is notified to the operator of the loading machine.

In addition, in this way, the approach of the vehicle to the loading machine is notified when the vehicle arrives at the position of the loading machine and the loading machine immediately starts loading the product into the vehicle. If the approaching vehicle arrives at the position of the loading machine, but the product is being loaded in the previous vehicle, etc. When the loading operation of the product in the previous vehicle is completed, the loading operation of this vehicle is started. Therefore, even if the receiver detects that the vehicle is approaching, the receiver Do not send approach information to.

  The management system described in Patent Document 1 detects the position and load weight of each work machine, and writes and reads the work start time and end time with an IC card. However, workers at the work site and operators of the work machine cannot know the work status such as the progress of work at the work site, and changes in work Since it can be known only by transmission through a person from the field office, there is a problem that after the change of work is determined, it cannot be known until this transmission is made, and a prompt action cannot be taken.

  For construction managers at site offices, the work machine position information, load weight, and time information cannot accurately grasp the work status of individual work machines, and It is not easy to determine whether or not the proper selection and arrangement of machines are made.

  Furthermore, when a plurality of work sites are close to each other, a work machine is assigned to each work site. In particular, a work machine such as a transport vehicle entering or leaving the work site erroneously enters another work site. There is a case. In order to avoid such a situation, when a worker is usually placed at the entrance of the work site and a work machine at another work site enters, the worker directly contacts the operator of this work machine. I am trying to notify you that it is wrong. However, in this case, such a worker is required at each work site, and when such a worker does not exist, the work machine enters and may hinder the work. is there.

  The present invention has been made in view of such points, and its purpose is to make it easy and reliable for the operator, the operator of the work machine, and the manager of the work to understand the work status at the work site. So that the operator of the work machine can easily grasp the current state of the work machine, and the administrator can easily determine whether the selection and arrangement of the work machine are appropriate. Is to provide a construction management system.

  In order to achieve the above-mentioned object, the present invention is a construction management system in which the work situation at the work site where the loading material is loaded onto the transport vehicle and transported by the loading machine is managed by the management device of the field office. A transmission means for transmitting the vehicle ID assigned to the transportation vehicle is provided for each transportation vehicle, and the vehicle transmitted from the transmission means when the transportation vehicle having the transmission means enters the work site at the work site. A base station for receiving the ID is provided, and the base station is communicable with the base station. When the base station starts receiving the vehicle ID, the time at that time is defined as the arrival time of the transport vehicle at the work site. When it becomes impossible to receive the vehicle ID, the time at that time is set as the departure time from the work site of the transport vehicle, and the vehicle time data of the arrival time and the departure time together with the received vehicle ID is managed. A server for transmission, the loading machine is communicable with the management device, and transmits loading machine time data of its own start time and stop time to the management device. Based on the loading machine time data, information for managing work information between the loading machine and the transport vehicle at the work site is created.

  Further, according to the present invention, the management device obtains the current work amount based on the received vehicle time data and transmits information on the current work amount to the loading machine. Based on the information on the amount of work, the current amount of work at the work site is displayed on the display unit.

  Furthermore, the present invention is characterized in that when there is a change in work at the work site, the management device transmits the work change information together with the current work amount information to the loading machine.

  Further, according to the present invention, the management device determines whether or not the transport vehicle has entered a predetermined work site based on the vehicle ID in the vehicle time data received from the server. When it is determined that the vehicle has entered another work site, the warning information is transmitted to the transport vehicle that has entered the other work site via the server that has transmitted the vehicle time data.

  Furthermore, the present invention has a means for the management device to analyze the work line balance by the work process based on the information on the work capability of the work machine in the work process at the work site, and based on the analysis result, It is characterized by assigning work machines for each work process.

  According to the present invention, the operator of the loading machine at the work site, the operator of the management apparatus, and the supervision of the work can surely confirm the work status and work changes at the work site, Even if a vehicle accidentally enters another work site, the operator of the transporting vehicle can immediately know such a situation, work efficiency can be improved, and the cost for work can be reduced and the addition of environment can be reduced. .

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a configuration diagram showing an embodiment of a construction management system according to the present invention, wherein A and B are construction sites, C is a field office, 1 is a loading machine, 2a, 2b and 2c are transport vehicles, and 3a. , 3b, 3c are IC tags, 4 is a base station, 5 is a server, 6 is a router, 7 is a network, and 8 is a management device.

  In this figure, it is assumed here that two construction sites A and B are set close to each other, but the present invention is not limited to this. Further, instead of the construction sites A and B, different work teams A and B at the same construction site may be used. However, below, it will be described as work sites A and B.

  Here, for convenience of explanation, the operations at these two construction sites A and B are the same, and accordingly, corresponding portions are denoted by the same reference numerals. For this reason, below, one construction site A is demonstrated unless it is required. However, the present invention is not limited to this, and the work contents at the construction sites A and B may be different.

  In the construction site A, here, an operation of transporting a loading material such as earth and sand from the construction site A to the outside is performed. For this purpose, a predetermined number of loading machines 1 and a predetermined number of transporting vehicles 2a, 2b, 2c (hereinafter referred to as the transport vehicle 2a when the transport vehicles at the construction site A are collectively referred to). Here, one loading machine 1 and three transport vehicles 2 are shown, but the present invention is not limited to this.

  The loading machine 1 performs a work of loading a load such as earth and sand at the construction site A into the transport vehicles 2a, 2b, and 2c, and the transport vehicles 2a, 2b, and 2c respectively load the loaded loads outside the construction site A. Transport to location. As the loading machine 1, a hydraulic excavator, a rotary snowplow, a belt conveyor, or the like is used according to the type of load or the situation at the site, and a dump truck or the like is used as the transport vehicle 2.

Each of the transport vehicles 2a, 2b, 2c is provided with IC tags 3a, 3b, 3c in which vehicle IDs assigned to the transport vehicles 2a, 2b, 2c are stored (the IC tags 3a, 3b, 3c are transport vehicles). 2a, 2b, 2c can also be carried by the operator, and hereinafter, the IC tags of the transport vehicles 2a, 2b, 2c at the construction site A will be collectively referred to as IC tags 3a).
Further, the construction site A is provided with a base station 4, and these IC tags 3a, 3b, 3c and the base station 4 are within a range of about 100 m by a wireless LAN compliant with, for example, IEEE 802.11b. Wireless communication is performed continuously or at a short constant cycle (for example, at intervals of 10 seconds). In other words, an area in the range of about 100 m centering on the base station 4 is the construction site A, and when the IC tags 3a, 3b, 3c are in the construction site A, they are periodically connected to the base station 4. If the wireless communication is performed and the IC tags 3a, 3b, 3c are outside the construction site A, the wireless communication with the base station 4 is not performed.

  When the base station 4 can wirelessly communicate with the IC tag 3a, the transport vehicle 2a having the IC tag 3a exists in the construction site A. When the wireless communication cannot be performed, the transport vehicle 2a exists in the construction site A. If the communication with the IC tag 3a that has been in communication is interrupted, it is determined that the transport vehicle 2a having the IC tag 3a has departed from the construction site A, and the IC that has not been in communication so far When communication with the tag 3a is started, it is determined that the transport vehicle 2a having the IC tag 3a has arrived at the construction site A. In this way, the base station 4 detects the departure from the construction site A and the arrival at the construction site A of each transport vehicle 2a used at the construction site A. This detection data is supplied to the server 5 together with the vehicle ID from the IC tag 3 received at this time. The server 5 uses the timer based on the detected data and the vehicle ID to obtain the departure time of the transport vehicle 2 with the vehicle ID from the construction site A and the arrival time at the construction site A. The vehicle time data is stored in association with the ID.

  In this way, the server 5 sequentially obtains the departure time from the construction site A and the arrival time at the construction site A associated with the transportation work of each transport vehicle input to the construction site A, and associates it with the vehicle ID. And stored as vehicle time data. Further, every time the vehicle time data is obtained, the server 5 adds the ID of the server 5 to the vehicle time data, and the management device 8 of the field office C via the router 6 and the network 7 such as the Internet. Sent to. The management device 8 stores the received vehicle time data in a storage unit described later.

  The loading machine 1 is provided with a control device that detects an on (start) operation and an off (stop) operation of a key switch for starting the engine. When the key switch is turned on, the loading machine 1 It is determined that the vehicle has started, and the start time is stored in the memory. When the key switch is turned off, it is determined that the loading machine 1 has stopped, and the stop time is stored in this memory. Here, the loading machine 1 and the field office C can communicate with each other via a wireless communication network such as the network 7 or the satellite communication network, and when the day work is completed, the detected start of the loading machine 1 is detected. The time and end time data are associated with the ID assigned to the loading machine 1 and transmitted as loading machine time data to the management device 8 of the field office C via the wireless communication network.

  In addition, even if it is a break time such as a lunch break, the key switch of the loading machine 1 is turned off and the loading machine 1 is stopped, but at this time, the work of the day is not finished. Therefore, in order to detect the end of the day's work by turning off the key switch of the loading machine 1, for example, information on the scheduled work end time is transmitted to the loading machine 1 from the monitoring device 8 in the field office C in advance. Based on this scheduled work end time, the key switch OFF operation time in the loading machine 1 is set as the work end time of the day. For example, when the scheduled work end time is set to 17:00 and the key switch of the loading machine 1 is turned off (that is, the operation to put the loading machine 1 in a stopped state) is performed after the scheduled work end time. The time when this off operation was performed is set as the end time of the day's work, and when this off operation is performed before this scheduled work end time, the time when this off operation was performed is stored, and thereafter If the key switch of the loading machine 1 is not turned on and the loading machine 1 is not restarted even when the scheduled work end time is reached, the stored time is set as the work end time of the day. In this way, when the work of one day is finished and this work end time is reached, the loading machine time data is transmitted from the loading machine 1 to the monitoring device 8. However, this is an example of a method for detecting the end of a day's work, and other methods may be used.

  Further, the server 5 can receive information from the management device 8 of the field office C via the network 7 and the router 6, and transmits such information from the base station 4 to the loading machine 1 or the transport vehicle 2a. be able to. Thereby, the work information from the management device 8 is transmitted to the server 5, and the server 5 stores the work information in the memory and transmits it to the loading machine 1 and the transport vehicle 2a. Thereby, in the loading machine 1 and the transport vehicle 2a, the received work information is displayed to the operator. Thereby, the operator can know the status of the work and the instruction from the field office C from this work information.

  Further, the loading machine 1 and the transport vehicles 2a, 2b, 2c used at the construction site A are registered and managed by the management device 8 of the site office C as being input to the construction site A. The loading machine 1 and the transport vehicles 2a, 2b, 2c used at the construction site B are also registered and managed by the management device 8 of the site office C as being input to the construction site B. As a result, the transport vehicles 2a, 2b, 2c used at the construction site A accidentally enter the other construction site B, and conversely, the transport vehicles 2a, 2b, 2c used at the construction site B are other construction sites. It is possible to prevent accidental entry into A.

  That is, the IC tags 3a, 3b, 3c provided on the transport vehicles 2a, 2b, 2c used at the construction site A can also communicate with the base station 4 at the construction site B other than the construction site A. For this reason, when this transport vehicle 2a, 2b, 2c accidentally enters another construction site B, the IC tags 3a, 3b, 3c communicate with the base station 4 of this construction site B, and the vehicle The ID is transmitted to the base station 4 of the construction site B. Therefore, when receiving the vehicle ID, the base station 4 at the construction site B transmits the vehicle time data of the transport vehicles 2a, 2b, 2c used at the construction site A to the management device 8 at the site office C. However, in this management apparatus 8, since the vehicle time data of the transport vehicles 2a, 2b, 2c used at the construction site A is received from the base station 4 at the construction site B, it is registered. Based on the information related to each transport vehicle and the construction site, it is determined that the transport vehicle 2a, 2b, 2c corresponding to the vehicle time data at this time has accidentally entered the other construction site B. The corresponding warning information is created and transmitted to the base station 4 of the construction site B that is the transmission source of the vehicle time data. As a result, the base station 4 of the construction site B transmits this warning information to the transport vehicles 2a, 2b, 2c of the construction site A that erroneously entered the construction site B, and enters the other construction site B. A warning that the correct construction site is the construction site A is sent to the operators of the transport vehicles 2a, 2b, 2c.

  This also applies to the case where the transport vehicles 2a, 2b, 2c used at the construction site B accidentally enter another construction site A, thereby monitoring the vehicle at each construction site at each entrance / exit. Without placing any personnel, the transport vehicles 2a, 2b, 2c can easily recognize that they have entered another construction site, and can quickly move to the correct construction site.

  Next, processing for managing the loading work at the construction sites A and B, which is executed by the management device 8 of the site office C, will be described. Here, although the construction site A will be described, it is assumed that there are three transport vehicles 2 that are put into the construction site A, and the vehicle IDs assigned to these transport vehicles, and therefore the terminal device 4 of the construction site A. Vehicle IDs stored in the IC tag 3 of these transport vehicles 2 that wirelessly communicate with each other are assumed to be 3a, 3b, 3c.

  FIG. 2 is a block diagram showing a specific example of the monitoring device 8 in FIG. 1, in which 8a is a data communication unit, 8b is a calculation unit, 8c is a storage unit, 8d is a display unit, and 8e is an input unit.

  In the figure, a monitoring device 8 includes a data communication unit 8a that performs data communication with the base station 4 (FIG. 1), an arithmetic unit 8b that performs arithmetic processing on various data received by the data communication unit 8a, A storage unit 8c for storing various data received by the data communication unit 8a and data obtained by calculation processing by the calculation unit 8b, and various types of data received by the data communication unit 8a and calculation processing by the calculation unit 8b. The display unit 8d includes a liquid crystal display device for displaying the obtained data and the like, and the keyboard for inputting the location of the construction site to be managed and the date on which the work is performed based on the display contents of the display unit 8d. An input unit 8e is provided.

  By operating the input unit 8e or the like, the calculation unit 8b causes the list data (that is, heavy machinery) of the loading machine 1 and the transport vehicles 2a, 2b, and 2c to be input to each construction site A and B shown in FIG. A database of arrangement list data) is created and stored / registered in the storage unit 8c. This heavy equipment arrangement list data is created by the operation of the operator of the input unit 8e, can be displayed on the display unit 8d, and can be corrected and changed.

  When the vehicle time data by the IC tags 3a, 3b, 3c from the base station 4 (FIG. 1) is received by the data communication unit 8a, the calculation unit 8b uses the server 5 added to the vehicle time data. In addition, it is determined whether the vehicle time data is transmitted from the server 5 of the correct construction site A or B based on the heavy equipment arrangement list data stored in the storage unit 8c, and the correct construction site A or B is determined. When the data is transmitted from the server 5, the correct vehicle time data is stored in the area for the corresponding construction site set in the storage unit 8c. When the vehicle time data is not transmitted from the server 5 at the correct construction site A or B, the calculation unit 8b discards the vehicle time data and also stores warning information stored in advance in the storage unit 8c. The corresponding warning information is searched from among them, and is transmitted from the data communication unit 8a to the server 5 that has transmitted the vehicle time data. Thereby, as mentioned above, the warning information concerning the operator of the transport vehicle 2 which entered into another construction site by mistake can be transmitted.

  In this way, the vehicle time data transmitted from the corresponding correct server 5 and received by the data communication unit 8a is stored in the storage unit 8c and is calculated by the calculation unit 8b to create vehicle work list data. And stored in the storage unit 8c. Hereinafter, the vehicle work list data at the construction site A (FIG. 1) will be described.

  FIG. 3 is data showing a specific example of such vehicle work list data, where 10 is the vehicle work list data, 11 is the vehicle ID, 12 is the arrival time, 13 is the departure time, 14 is the dwell time, and 15 is between the vehicles. The cycle time, 16 is a cycle time for each vehicle, and 17a to 17g are vehicle work data.

  In the figure, the vehicle work list data 10 includes vehicle work data 17a to 17g created based on the received vehicle time data, and the vehicle work data 17a to 17g is received vehicle time data. Vehicle ID 11, arrival time 12, departure time 13, residence time 14, inter-vehicle cycle time 15, and vehicle-specific cycle time 16. Here, the vehicle ID 11 is the vehicle ID in the received vehicle time data, the arrival time 12 is the arrival time in the received vehicle time data, and the departure time 13 is the departure time in the received vehicle time data. .

  The staying time 14 is the time during which the transport vehicle 2 stays at the construction site A, and is the time from the arrival time 12 to the departure time 13 in the same vehicle work data 17 (generic name of the data 17a to 17g). When the vehicle time data of the arrival time is received and the next vehicle time data of the departure time by the same IC tag 3 is received, these are stored in the storage unit 8c as the arrival time 12 and the departure time 13 of the vehicle work data 17, respectively. At the same time, the arrival time 12 and the departure time 13 are read out and processed by the calculation unit 8b, and the residence time 14 is created and stored in the storage unit 8c. For example, for the vehicle work data 17a, since the arrival time 12 is 8:10 and the departure time is 8:15, the residence time 14 is 5 minutes (= 0: 05).

  The inter-vehicle cycle time 15 is the time from when the transport vehicle 2 arrives at the construction site A until the next transport vehicle 2 arrives at the construction site A. When the vehicle time data of the arrival time is received, When the vehicle time data of the arrival time is received, these arrival times are stored as the arrival time 12 of the vehicle work data 17, and at the same time, these arrival times 12 are read out and processed by the calculation unit 8b. The difference time is stored in the storage unit 8c as the inter-vehicle cycle time 15 of the vehicle work data that is received later. When a plurality of transport vehicles are put into the construction site A, the transport vehicle 2 that is different from the arrival time of the vehicle time data that is normally received first and the arrival time of the vehicle time data that is received later is accordingly. , For different vehicle IDs. In the example shown in FIG. 3, after the transport vehicle 2a with the vehicle ID 3a arrives at the construction site A at 8:10, the transport vehicle 2b with the vehicle ID 3b next arrives at the construction site A at 8:20. As a result, the inter-vehicle cycle time 15 in the vehicle work data 17b with the vehicle ID 3b is 10 minutes (= 0: 10).

  The cycle time 16 for each vehicle is the time from when the transport vehicle 2 arrives at the construction site A until the same transport vehicle 2 arrives at the construction site A, and the vehicle time data of the arrival time is received. When the vehicle time data of the next arrival time of the same vehicle ID is received, these arrival times are stored as the arrival time 12 of the vehicle work data 17. At the same time, these arrival times 12 are read and calculated. An arithmetic process is performed in the unit 8b, and the time of these differences is stored in the storage unit 8c as the vehicle-specific cycle time 16 of the vehicle work data on which the vehicle time data is received later. When one transport vehicle is put in the construction site A, the cycle time 16 for each vehicle is equal to the cycle time 15 between vehicles. In the example shown in FIG. 3, after the transport vehicle 2a with the vehicle ID 3a arrives at the construction site A at 8:10, the transport vehicle 2a with the same vehicle ID 3a is next to the construction site A at 8:41. As a result, the inter-vehicle cycle time 15 in the vehicle work data 17d with the vehicle ID 3a is 31 minutes (= 0: 31).

  In FIG. 1, when one day of work is completed (that is, when the key switch for ending the day of work is turned off by the loading machine 1 at the construction site A as described above), as described above. The loading machine time data is transmitted from the loading machine 1 to the management device 8 of the field office C. In this management device 8, in FIG. 2, the loading machine time data is received by the data communication unit 8a, and is calculated by the calculation unit 8b to create loading machine operation data, which is stored in the storage unit 8c. In this calculation process in the calculation unit 8b, loading machine operation data of the loading machine 1 is created.

  FIG. 4 is a diagram showing a specific example of such loading machine operation data, wherein 18 is loading machine operation data, 19 is a start time, 20 is a stop time, 21 is an operation time, 22 is a daily operation time, 23a Is the first half work time data, and 23b is the second half work time data.

  In the figure, from the received loading machine time data, the first half work time data 23a for the first half work of the day (from when the loading machine 1 is first started to stop) and the second half work (loading). The second half work time data 23b for the machine 1 from the second start to the stop) are created and stored as loading machine operation data 18 in the storage unit 8c.

  The first half work time data 23a and the second half work time data 23b include a start time 19 that is a start time in the received loading machine time data, a stop time 20 that is also a stop time, an operation time 21, and a daily The operation time 22 is included.

  The operation time 21 is obtained for each of the first half work time data 23a and the second half work time data 23b, and is the time from the start time 19 to the stop time 20. In the illustrated example, the operation time 21 of the first half work time data 23a is 12: 00-8: 00 = 4: 00 (4 hours), and the operation time 21 of the second half work time data 23b is 17: 00-12. : 45 = 4: 15 (4 hours 15 minutes).

  The daily operating time 22 is a daily operating time of the loading machine, and is the total time of the operating time 21 of the first half working time data 23a and the working time 21 of the second half working time data 23b. 0: 00 + 4: 15 = 8: 15 (8 hours 15 minutes).

  The time between the stop time 20 of the first half work time data 23a and the start time 19 of the second half work time data 23b is recognized as a lunch break time (lunch break time), and is associated with the loading machine operation data 18 and the storage unit. Store in 8c.

  In addition, here, the work is the first half of the morning work and the second half of the afternoon work, but if the night work is performed and there is a break between the afternoon work and the night work, loading is performed. As the machine operation data 18, the first half work time data 23a becomes morning work time data, the second half work time data 23b becomes afternoon work time data, and the night work time data is added thereto. The end time of the day work is the time at which the end of the night work is detected by setting the work end time as described above for the night work. Then, the time between the stop time 20 of the afternoon work time data 23b and the start time 19 of the night work time data is detected as a break time.

  The residence time 14, the vehicle cycle time 15, and the vehicle cycle time 16 in the vehicle work list data 10 shown in FIG. 3 are obtained by removing such rest time.

  FIG. 5 is a diagram showing the vehicle work data in the vehicle work list data 10 shown in FIG. 3 when arriving at the construction site before the break time and leaving the construction site after the break time. The portions corresponding to FIG. 3 are denoted by the same reference numerals and redundant description is omitted.

  In this figure, in this case, from the loading machine 1, for example, vehicle time data with an arrival time of 11:50 is received by the data communication unit 8a from the transport vehicle 2a with the vehicle ID 3a and stored in the storage unit 8c. If the vehicle time data having a departure time of 12:50 is received from the same transport vehicle 2a and then stored in the storage unit 8c from the same transport vehicle 2a and stored in the storage unit 8c, the stored vehicle 8a is stored in the storage unit 8c. In the vehicle work data 17h, the arrival time 12 is 11:50 as it is, and the departure time 13 is 12:50 as it is. And when this departure time 13 is memorize | stored, the calculating part 8c reads these arrival time 12 and departure time 13, calculates these, and calculates | requires the residence time 14 of the transport vehicle 2a at this time, Between the arrival time 12 at 11:50 and the departure time 13 at 12:50 at this time, the break time (12: 0 to 12:45) detected from the loading machine operation data 18 shown in FIG. Therefore, except for the break time of 0:45 (45 minutes), 12: 50-11: 50-0: 45 = 0: 15 is set as the residence time of the transport vehicle 2a at this time, and this is the vehicle work. The residence time is 14 in the data 17h.

  The same applies to the inter-vehicle cycle time 15 and the vehicle-specific cycle time 16 in the vehicle work list data 10 shown in FIG. 3, and the break time is excluded.

  In this way, even if there is a break time, the dwell time 14 at the construction site of the transport vehicle 2, the cycle time 15 between vehicles, and the cycle time 16 for each vehicle are obtained as excluding the break time. Thus, the actual working time can be obtained accurately, and the loading work can be properly managed.

  In the vehicle work list data 10 shown in FIG. 3, each transport vehicle 2 arrives at the construction site, and every time the loading material 1 such as gravel is loaded by the loading machine 1, a new vehicle is departed. Although the work data 17 is completed and increases, as the new vehicle work data 17 is completed, the vehicle work aggregation is performed based on the vehicle work list data 10 that has been created by the calculation unit 8b (FIG. 2). When the list data is created and updated, and the work for one day is completed, the vehicle work total list data obtained by totaling the one day work is created and stored in the storage unit 8c.

  FIG. 6 is a diagram showing a specific example of such vehicle work summary list data, where 24 is the vehicle work summary list data, 25 is the vehicle ID, 26 is the number of times of transportation, 27 is the amount of soil, 28 is the average residence time, 29 Is the average vehicle cycle time, 30a to 30c are vehicle work total data, and 31 is total data.

  In the figure, based on the vehicle work list data 10 shown in FIG. 3, vehicle operation total data 30 a to 30 c and total total data 31 are created by the calculation unit 8 b for each vehicle ID and accordingly for each transport vehicle 2. Then, it is stored in the storage unit 8c as vehicle work total list data 24.

  Here, the vehicle work list data 10 includes vehicle work total data 30a, 30b, and 30c with vehicle IDs 25a, 3b, and 3c, and these vehicle work total data 30a, 30b, and 30c are up to the present. The number of transports 26, the amount of soil transported 27 to date, the average residence time 28 to date, and the cycle time by vehicle average to date.

  Here, if the vehicle work list data 10 shown in FIG. 3 is based on the work up to now, the number of times of transportation 26 is the number of times of transportation for each of the transportation vehicles 2a, 2b, 2c, and the vehicle work list shown in FIG. According to the data 10, the transport vehicle 2a (vehicle ID = 3a) is three times up to the present, the transport vehicle 2b (vehicle ID = 3b) is twice, and the transport vehicle 2c (vehicle ID = 3c) is two times until the present. It will be transported.

The amount of soil 27 is the total transport amount (m ² ) up to the present of the loading material such as the earth and sand for each transport vehicle 2a, 2b, 2c. In the storage unit 8c, a load amount (a single transfer amount) is previously input from the input unit 8e (FIG. 2) and stored for each of the transport vehicles 2a, 2b, and 2c. Is multiplied by the calculation unit 8b, and the soil volume 27 is obtained and stored in the storage unit 8c. Here, any of the transport vehicles 2a, 2b, 2c has a loading capacity of 5.5 m ³ up to the present time, and therefore the soil volume 27 of the transport vehicle 2 a is 5.5 m ³ × 3 times = 16.5 m ^3. The soil volume 27 of the transport vehicles 2b and 2c is 5.5 m ³ × 2 times = 11 m ³ .

  The average residence time 28 is the average time until the present residence time 14 for each of the transport vehicles 2a, 2b, 2c in the vehicle work list data 10 shown in FIG. 3, for example, the vehicle of the transport vehicle 2a with the vehicle ID 3a. The work total data 30a is (0: 05 + 0: 05 + 0: 04) / 3≈0: 05 (rounded to the nearest minute).

  The average vehicle cycle time 29 is the average time to date of the vehicle cycle time 16 for each of the transport vehicles 2a, 2b, and 2c in the vehicle work list data 10 shown in FIG. 3, for example, transport with a vehicle ID of 3a. The vehicle work total data 30a of the vehicle 2a is (0: 31 + 0: 32) / 2≈0: 05 (rounded to the nearest minute).

The total sum data 31 is data represented by the total number of driving times 26 and the total amount of soil 27 in each of the transport vehicles 2a, 2b, 2c (vehicle IDs 3a, 3b, 3c). Therefore, the transport count 26 in the total sum data 31 is 3 + 2 + 2 = 7, and the soil volume 27 is 16.5 + 11 + 11 = 38.5 m ³ .

  The vehicle work summary list data 24 created in this way is stored in the storage unit 8c, but is read from the storage unit 8c by the operation of the display command in the input unit 8e (FIG. 2), and the display unit 8d. (FIG. 2). As a result, the operator of the management device 8 and the supervision of the construction site can grasp the current amount (soil volume) of each transport vehicle 2 and the daily amount of this day. Reward for transportation work can be calculated easily and accurately from the amount of shipment, and the total amount of shipment per day (total soil volume) can be grasped, so whether the progress of construction is appropriate or not Judgment can be easily made. In addition, since the average residence time and average cycle time per day of each transport vehicle 2 can be grasped, it becomes possible to easily determine the work status such as the suitability of the load capacity and the presence or absence of failure for each transport vehicle 2. .

  Further, as shown in FIG. 4, the daily work is completed, and the loading machine operation data 18 for the day is created as shown in FIG. 4, and the daily vehicle work summary list data 24 is created as shown in FIG. Then, based on the loading machine operation data 18 and the vehicle work totalization list data 24, the calculation unit 8b (FIG. 2) totals the work of the heavy equipment (loading machine 1 and transport vehicle 2) for one day. Heavy machine work data is created and stored in the storage unit 8c.

  FIG. 7 is a diagram showing a specific example of such heavy machinery work data, wherein 32 is heavy machinery work data, 33 is the number of loadings, 34 is heavy machinery operating time, and 35 is pitch time.

  In the figure, heavy equipment work data 32 is composed of a loading number 33, a heavy equipment operating time 34, and a pitch time 35. The loading number 33 is the total sum data 31 of the vehicle work total list data 24 shown in FIG. 4, that is, the total number of times the transport vehicles 2a to 2c are transported on that day, and the heavy equipment operating time 34 is the work time excluding the rest time on that day, and is shown in FIG. This is the daily operating time in the operating data 18. The pitch time 35 is the time required for one transport operation of the transport vehicle 2 and is represented by heavy equipment operating time 34 ÷ loading number 33. In this case, pitch time 35 = 8: 15 ÷ 7 = 1:10 (1 hour 10 minutes).

  The heavy machinery work data 32 is also read from the storage unit 8c and displayed on the display unit 8d by a predetermined operation of the input unit 8e of the monitoring device 8 (FIG. 2). Thereby, since the index for managing the productivity of the construction site can be obtained from the pitch time 35, it becomes possible to improve the productivity at the construction site based on the index.

  In the above description, the display of the vehicle work summary list data 24 (FIG. 6) and the heavy machinery work data 32 (FIG. 7) on the display unit 8d has been described. However, the vehicle work list data 10 is displayed according to the operation of the input unit 8e. (FIG. 3) and loading machine operation data 18 (FIG. 4) can also be displayed on the display unit 8d. Thereby, it is possible to grasp the work status of each heavy machine.

  As described above, the monitoring device 8 displays data such as the work status at the construction site on the display unit 8d, and this can be grasped by the operator or the construction site supervisor. Work result information and work change information are transmitted as notification information from the device 8 to the loading machine 1 at each construction site. In the loading machine 1, the notification information is received and displayed on a display unit provided in the loading machine 1. As a result, work results and work changes are notified to the operator of the loading machine 1.

  Such notification information is created based on the above-described various data stored in the storage unit 8c by a predetermined operation at the input unit 8e of the monitoring device 8, and is instructed by the input unit 8e from the data communication unit 8a. To the loading machine 1 at the construction site. The notification information may be automatically generated at a predetermined time interval and transmitted to the loading machine 1 or may be transmitted in response to a request from the loading machine 1. . However, the construction information change notification information is automatically transmitted to the corresponding loading machine 1 immediately after the information necessary for the change notification is input by the input unit 8e and created by the calculation unit 8b. The

  FIG. 8 is a diagram showing a specific example of a work result information screen (work result display screen) displayed on the display unit of the loading machine 1 in FIG. Is a current work amount, 38 is a current work amount, 39 is a work achievement level, 40 is work information, and 41 is a work change notification unit.

  The work result display screen 36 shown in FIG. 8A is for notifying the operator of the loading machine of only the work result. The target work amount 37, the current work amount 38, and the work achievement degree 39 of today. And work information 40 is displayed.

Today's target work amount 37 is input from the input unit 8e of the monitoring device 8 (FIG. 2), is stored in the storage unit 8c, and is transmitted when notification information is transmitted to the loading machine 1. The notification information is created by reading from the storage unit 8c. Further, the current work amount 38 is the soil amount 27 of the total summary data 31 in the current vehicle work summary list data 24 shown in FIG. 6, and is stored when the notification information is transmitted to the loading machine 1. The notification information is created by reading from the unit 8c. The work achievement degree 39 is a ratio of the current work amount 38 to the today's target work amount 37 represented by a graph and a numerical value. As shown in the figure, the current work amount 37 = 300 m ^{3 of} the present day, If the work amount is 38 = 210 m ³ , the work achievement degree is 39 = 70%.

  Further, the work information 40 represents today's work contents and work places, and here, as an example, the work contents are excavated earthwork and the work place is “cinch number 33-35”.

  As described above, the work result display screen 36 is displayed on the display unit of the loading machine 1 so that the construction site where the work should be performed can be confirmed when starting the work. The work can be performed without fail, and the operator of the loading machine 1 can grasp the progress of the work at the present time.

  When notifying the operator of the loading machine 1 of the work content, as shown in FIG. 8B, a work change notification unit 41 is added to the display content of the work result display screen 36 shown in FIG. Is displayed. Here, from the excavation earth work at the construction site of “Tightening number 33-35” shown in FIG. 8A, the slope shaping at the construction site of “Tightening number 40” shown in FIG. 8B. This shows the case where the work is changed.

  In this way, when there is a change in the work content, the operator of the loading machine 1 can know the work content to be changed along with the work results from the screen, which is more reliable than the message from the worker or the like. Therefore, it is possible to grasp the work contents to be changed and to deal with the change immediately.

  Note that the change notification of the work content is also notified to the corresponding transport vehicle.

  When performing construction, the work involves multiple work processes. To achieve the target work within the specified period, each work process must be performed efficiently and in a balanced manner. It is necessary to be able to For this reason, when construction is performed, the line balance of a series of work processes for this work is analyzed, and the type and number of work machines used in each work process are determined.

  For example, when excavation work is performed at the construction site, excavation work using excavation work machines such as backhoes, soil improvement work using soil improvement machines, loading work using loading machines such as backhoes, dump trucks, etc. There is a soil transporting work with a transport vehicle, a leveling work for leveling the excavated ground with a bull tosa, a compacting work for compacting the leveled ground with a roller, etc., but the line balance of such work By analysis, the number of work machines used as backhoes or dump trucks for each work process is determined.

  FIG. 9 is a list showing the work capacity per hour and the target work amount of the work machine used in each work process for performing such line balance analysis, 42 is a work capacity list, and 43 is a work machine. Name 44, work machine type, 45 work ability, 46 work name, 47 remarks, 48 is a target value.

  In this figure, the work capacity list 42 shows excavation, soil improvement, loading, soil transport, leveling, and compacting work, as shown by Tsuna name 46, taking excavation work as an example. The backhoe of excavation work and loading work is determined so that the work machine used in each work process is represented as work name 43, such as a dump truck being used for soil transport work. Is done. Further, as the work machine used, as shown in work machine type 44, the backhoe is BH0.7 and the dump truck is DP10t.

The work capacity per hour of each work machine used in each work process is acquired from predetermined materials as indicated by work capacity 45. For example, excavation amount and loading per hour of backhoe BH0.7 is 64.51M ^3, soil transportation amount per hour of the dump truck DP10t is 8.07m ^3. Therefore, in order to transport the soil of 64.51m ³ of excavation and loading amount per hour of the backhoe in the same hour, 644.51m ³ ÷ 8.07m ³ = 8 DP10t dump trucks This is described in Remark 47, although it is necessary. In the remark 47, necessary items are described.

  As the target value 48, for example, the number of workable days, the target soil transport amount per day, the target compaction soil amount per day, and the like are described.

  Each data of the work capability list diagram 42 is input by the operator from the input unit 8e in the management apparatus 8 (FIG. 2) of the field office, and is stored as the work capability list diagram 42 under the processing of the calculation unit 8b. Stored in the unit 8c. Then, by the operation of the input unit 8e, the calculation unit 8b performs work line balance in a series of work processes set in the work name 46 of the work capability list diagram 42 based on the data of the work capability list diagram 42. Analyze

  FIG. 10 is a diagram showing an analysis example of work line balance, 49 is a work machine, 50 is a work amount per hour, 51 is a work amount per day, 52 is a pitch time, 53 is a work balance rate, 54 Is the work line organization loss rate.

  FIG. 10A shows a work machine 49, one excavating machine BH, one loading machine BH, eight dump trucks, one leveling bull tozer, and compaction work. The work line balance when the work type using one roller is type A is shown.

In this case, as shown as the work amount 50 per hour according to the work capability list 42 shown in FIG. 9, the excavation work amount per hour of the excavating machine BH and the loading work per hour of the loading machine BH the amount is 64m ^3, soil transportation amount per hour of the dump truck eight is a 8m ³ × eight = 64m ^3, work amount of the day, the work time of the day as 7 hours As shown as the work amount 51 per day, all are 64 m ³ × 7 = 448 m ³ . The work machines other than these are also as illustrated in FIG.

In addition, the amount of soil transport per hour for 11 dump trucks is 8m ³ × 11 units = 88m ³ , and the daily work amount of the loading machine BH and the dump truck is 2 loading machines BH. 128m ³ × 7 hours = 896m ³ , 11 dump trucks 88m ³ × 7 hours = 616m ³ , reaching the target soil transport amount of 600m ³ per day shown in the list of work capacity shown in FIG. However, the excavation amount of the excavating machine BH per day is 448 m ³ , and it will not be in time for loading by the loading machine BH or transportation by the dump truck.

  As shown in the drawing, the pitch time 52 becomes 0.015625 at the maximum by excavation work by the excavating machine, and this excavation work is a bolt neck process.

  The work line balance rate 53 is 0.68, the work line organization loss rate 54 is 0.32, and the work line balance rate is improved as compared with the case of FIG.

In the analysis shown in FIG. 10 (b), it is assumed that the soil improvement work is preceded by 2.5 days, and therefore the work amount 52 per day is 57 m ³ × 7 hours × 2 .5 days = 998 m ³ .

  10C shows two excavating machines BH as shown as the working machine 49, and the other working machines are of the type C as in the case of FIG. 10B.

In this case, as shown as the work amount 50 per hour according to the work capability list diagram 42 shown in FIG. 9, the work amount per hour of the two excavating machines BH is 128 m ³ and the work per day. The amount is 128 m ³ × 7 hours = 896 m ³ , which is equal to the daily work amount of the two loading machines BH and 11 dump trucks that have reached the target soil transport amount per day.

  In addition, as shown in the drawing, the pitch time 52 becomes a maximum of 0.0125 in the spread leveling operation, and this spread leveling operation becomes the bolt neck process.

  The work line balance rate 53 becomes 0.79 and the work line organization loss rate 54 becomes 0.21, which further improves the work line balance rate compared to the case of FIG.

  In this manner, the obtained work line balance analysis result is stored in the storage unit 8c, and can be read from the storage unit 8c and displayed on the display unit 8d by an instruction operation from the input unit 8e.

  FIG. 11 is a diagram showing the analysis result of the work line balance shown in FIG.

  FIG. 11A shows the arrangement of work machines in each work process for each of types A, B, and C. Data of the work machine 49 in FIGS. 10A, 10B, and 10C is shown. It is based on.

  FIG. 11B shows the work line balance rate, the work line organization loss rate, and the planned amount of soil transport per day for each of types A, B, and C. The work line balance rate is shown in FIG. The work line knitting loss rate is also based on the work line knitting loss rate 54 and the work line knitting loss rate 54 is the same as the work line balance rate 53 in (b) and (c). Based on daily soil transport by dump trucks.

  FIG. 11C is a graph showing the work line balance rate and the work line organization loss rate of types A, B, and C.
