Description

  The present invention relates to a transportation management system that performs transportation management when a material or the like is transported by a truck or the like.

A fill dam is one of the types of dams, and is a dam embankment built up of natural earth and sand and rocks, unlike concrete dams that are mainly made of concrete. (See, for example, Patent Document 1)
The fill dam has a zone in which “core material” is used, a zone in which “filter material” is used, a zone in which “internal lock” is used, and a zone in which “external lock” is used as rock / sediment materials. Therefore, when the dam is built, the rock and earth and sand materials loaded on the dump truck must be unloaded into the correct zone.

Conventionally, at the filling site of a fill dam, the worker visually confirms the rock and earth and sand material loaded on the dump truck at an appropriate passing point on the site, and the worker checks the load on the dump truck driver. The destination to be lowered is indicated.

  When a worker instructs a driver to go to a destination, the destination is often indicated by a megaphone or a signboard. However, according to such a method, unloading is performed in an incorrect zone due to a human error. There was a problem that there was a fear that an accident might occur in which the worker might come into contact with the dump truck.

  In view of this, it is conceivable to carry out transport management of rocks and earth and sand materials at the filling site of the fill dam with an information communication terminal such as a smartphone carried by a dump truck worker. However, according to such a method, the initial cost for preparing the information communication terminals for the number of dump trucks used in the field and the communication costs for the information communication terminals are necessary, so the new cost is high. A problem occurs.

  This invention solves the said subject, The invention which concerns on Claim 1 is installed in a truck, ID acquisition means which acquires ID uniquely allocated to the onboard equipment used for collection of tolls, Corresponding to the ID acquisition means, the loading material recording means for recording the loading material loaded on the truck, and the loading / unloading zone of the truck based on the loading material recorded on the loading material recording means. It is a transportation management system characterized by comprising determination means for determining whether or not.

  According to a second aspect of the present invention, in the transport management system according to the first aspect of the present invention, the transport management system further comprises a display device that performs display based on the loaded material recorded in the loaded material recording means.

  The invention according to claim 3 is characterized in that, in the transportation management system according to claim 1 or 2, a warning means for performing an operation according to a determination result of the determination means is provided.

  The transportation management system 10 according to the present invention records the loading material corresponding to the ID uniquely assigned to the vehicle-mounted device used for toll collection, and based on this, whether the truck unloading zone is correct or not is recorded. Therefore, it is possible to carry out accurate truck unloading without incurring communication costs of the information communication terminal, without incurring costs, and without relying on workers.

Absent. For example, in transporting debris, various types of debris are transported for each truck. The transport management system 10 of the present invention can be suitably used for transporting such debris. .

  In the present embodiment, the transport management system 10 is assumed to be used at the fill dam site, but the transport management system 10 of the present invention is limited to use at the fill dam site. It is not something. For example, the transportation management system 10 of the present invention can be applied to a construction site on a hill.

  Hereinafter, in the present embodiment, transport management when a predetermined material at the material loading site is loaded on the dump truck 20 and unloaded at a predetermined zone at the fill dam building site will be described. It is assumed that when the dump truck 20 leaves the material loading site and enters the preparation site, it passes through the site gate. In addition, a plurality of dump trucks 20 are used, and the plurality of dump trucks 20 reciprocate between the material loading site and the preparation site and supply each material on the material loading site to the preparation site.

  In the present embodiment, the dump truck 20 which is a transport means can unload the a material loaded at the “a material loading site” at the charge loading site in the “A zone” at the preparation site, The b material loaded at the “b material loading site” at the material loading site can be unloaded at the “B zone” at the preparation site, and the c material loaded at the “c material loading site” at the material loading site. The material can be unloaded at the “C zone” at the preparation site, and the d material loaded at the “d material loading site” at the material loading site is unloaded at the “D zone” at the preparation site. It is assumed.

  In the filling of the fill dam, for example, a material corresponds to “core material”, b material corresponds to “filter material”, c material corresponds to “internal lock”, and d material corresponds to “external lock”. To do.

In the operation management system 10 according to the present invention, the use of the on-board device 21 of ETC used for toll collection is one of the major features. The ETC performs two-way wireless communication using the DSRC (Dedicated Short Range Communication) method between the roadside device installed at the toll booth and the vehicle-mounted device 21 mounted on the vehicle, and pays the toll. It is a system that transmits and receives information necessary for

  Each vehicle-mounted device 21 is assigned a unique ID (equipment-specific information) called a device number, and the ID of the vehicle-mounted device 21 can be read by the bidirectional wireless communication. ing. Such a vehicle-mounted device 21 is attached to all the dump trucks 20 that transport materials for dam building.

  The antenna 11 is means for reading the ID of the vehicle-mounted device 21 as described above. The antenna 11 is provided in each material loading place, on-site gate, and each zone, and can read the read ID to the database system 15. ing. The antennas 11 are installed at a sufficient interval so as not to read the ID of the vehicle-mounted device 21 of the same dump truck 20.

  Note that a suffix (a, G, etc.) corresponding to the installation location is attached to the reference number of the antenna 11. The database system 15 is configured to communicate with each component via a communication line such as the Internet.

  Further, in the present embodiment, an example in which only one antenna 11 is provided in each loading place or zone has been described, but it seems that it is desired to detect the presence of the dump truck 20 (the vehicle-mounted device 21) in a wider range. In this case, a plurality of antennas can be provided in each loading place or each zone.

  An indicator 13 is provided at a position where the driver of the dump truck 20 can visually check, together with the antenna 11G, at the site gate, which is the entrance of the erection site. The display of the display 13 is controlled by a display control signal transmitted from the database system 15.

  An electronic bulletin board 12 that functions as a warning light or the like is provided in each zone at the serving site as a notification means to the driver of the dump truck 20. These electronic bulletin boards 12 operate according to an electronic bulletin board control signal transmitted from the database system 15.

  The database system 15 can be a general one used for information processing, such as a cloud server, but can be used other than the database system 15 as long as it can perform information processing. . For example, a dedicated circuit for performing information processing similar to the database system 15 in the present invention may be provided.

  The database system 15 is connected to each antenna 11, the display 13, and each electronic bulletin board 12 so that information communication is possible. The database system 15 receives ID data from each antenna 11, and The output from 15 is input to each electronic bulletin board 12 and display 13.

Next, an algorithm for processing in the operation management system 10 according to the present invention configured as described above will be described. The algorithm in the operation management system 10 is executed by the database system 15.

  First, processing when the dump truck 20 loads material at the material loading site will be described. In the following example, the dump truck 20 is loaded with the material “a” at the “a material loading field” at the material loading site, is transported by the dump truck 20, and is further “ The explanation is based on the case of unloading the material “a”. Other materials can be considered in the same manner as in the case of the material “a”, and thus description thereof will be omitted.

  FIG. 2 is a diagram showing a flowchart of material loading processing in the transport management system 10 according to the embodiment of the present invention, and FIG. 3 is a diagram schematically showing a state of material loading.

  As shown in FIG. 3, when the dump truck 20 approaches the a material loading place for loading a material, the antenna 11 a can read the ID of the vehicle-mounted device 21 mounted on the dump truck 20.

  In the flowchart of FIG. 2, it is assumed that the ID of the vehicle-mounted device 21 mounted with the dump truck 20 is read as described above.

  In the flowchart of FIG. 2, when the material loading process is started in step S100, it is determined in step S101 whether or not the ID of the vehicle-mounted device 21 is detected.

  If the determination is YES, the process proceeds to step S102, where it is determined whether or not the “loading flag” corresponding to the ID is 0. The “loading flag” is a flag that takes “1” when it is assumed that the dump truck 20 is already loaded with material, and takes “0” otherwise.

  If the determination in step S102 is YES, the process proceeds to step S103, the ID unique to the vehicle-mounted device 21 is recorded in the storage means (not shown) of the database system 15, and then the process proceeds to step S104, corresponding to the antenna 11a. Record the loading material. In this example, the material is “a”.

  In step S105, the time counted by the database system 15 is recorded. In the next step S106, the loading flag is set to 1.

  Recording data as shown in FIG. 8A is stored in the database system 15 by the algorithm of the flowchart as described above. FIG. 8 is a diagram showing an example of the data format of data stored in the database system 15. As shown in FIG. 8, in the present embodiment, the data formats include “vehicle equipment unique ID”, “number plate information”, “loading material”, “acquisition time”, “loading flag”, and “gate passage flag”. Each item is stored. Further, it can be set to store other items. In addition, about "number plate information", it can prepare beforehand corresponding to "vehicle equipment specific ID".

  Next, the process when the dump truck 20 that has started from the material loading site as described above passes through the gate at the erection site will be described.

  FIG. 4 is a view showing a flowchart of the process at the time of passing the gate in the transport management system 10 according to the embodiment of the present invention, and FIG. 5 is a view schematically showing the state of the process at the time of passing the gate.

  As shown in FIG. 5, since the dump truck 20 carries the loaded a material to the building site, the ID of the vehicle-mounted device 21 mounted on the dump truck 20 can be read by the antenna 11G when passing through the site gate. It becomes like this.

  In the flowchart of FIG. 4, it is assumed that the ID of the vehicle-mounted device 21 mounted with the dump truck 20 is read as described above.

  In FIG. 4, when the process at the time of gate passage is started in step S200, it is determined in step S201 whether or not an ID unique to the vehicle-mounted device 21 is detected.

  Subsequently, in step S202, it is determined whether or not the stack flag in the recording data corresponding to the ID is 1. If the loading flag is not 1, the process proceeds to step S206 and the display 13 is not displayed. This is because, when the loading flag is not 1, the dump truck 20 equipped with the vehicle-mounted device 21 is highly likely to be a dump truck that exits the erection site.

  In step S203, it is determined whether or not the gate passage flag is 1. Here, the “gate passing flag” is a flag that takes “1” when it is assumed that the dump truck 20 has already passed the field gate, and takes “0” otherwise. is there.

  If the determination in step S203 is YES, the dump truck 20 on which the vehicle-mounted device 21 is mounted is considered to be a dump truck that exits from the building site, so the process proceeds to step S207 and the gate passing flag is set to 0. Set.

  If the determination in step S204 is NO, the process proceeds to step S204, the recorded data is referred to, an instruction corresponding to the loaded material is displayed on the display unit 13 and, together with this, a license plate for confirmation. Display information. In step S205, the gate passing flag is set to 1.

With respect to the dump truck 20 entering the preparation site by the algorithm of the flowchart as described above, the recording data as shown in FIG. 8B is stored in the database system 15 and the dump truck exiting from the preparation site. With respect to the truck 20, recording data as shown in FIG. 8 (D) is stored in the database system 15. Next, processing when the dump truck 20 that has passed through the gate unloads in the A zone of the building site. Will be described.

  FIG. 6 is a diagram showing a flowchart of the unloading process in the transport management system 10 according to the embodiment of the present invention, and FIG. 7 is a diagram schematically showing the state of the unloading process.

  As shown in FIG. 7, when the dump truck 20 approaches the A zone for the unloading of the material a, the ID of the vehicle-mounted device 21 mounted on the dump truck 20 can be read by the antenna 11A.

  In the flowchart of FIG. 6, it is assumed that the ID of the vehicle-mounted device 21 mounted with the dump truck 20 is read as described above.

  In FIG. 6, when the unloading process is started in step S300, it is determined in step S301 whether an ID unique to the vehicle-mounted device 21 is detected.

  If the determination in step S301 is yes, the process proceeds to step S302, and it is determined whether or not the correspondence between the unloading zone and the loaded material of the recording data is correct. In this example, it is determined whether the “A zone” and the “a material” match.

  If the determination in step S302 is YES, it is considered that the correct material has been unloaded, so the process proceeds to step S303, displaying that the correct unloading has been performed on the electronic bulletin board 12, and subsequently, step S304. To set the loading flag to 0.

  On the other hand, if the determination in step S302 is NO, the wrong material may be unloaded, so the process proceeds to step S305 to display on the electronic bulletin board 12 that correct unloading has not been performed and the dump truck. Inform the 20 drivers of the error. In the present embodiment, the electronic bulletin board 12 is used as a warning / notification means for the driver of the dump truck 20, but any warning / notification means can be used.

  With respect to the dump truck 20 that has been unloaded according to the algorithm of the flowchart as described above, record data as shown in FIG. 8C is stored in the database system 15.

  As described above, the transportation management system 10 according to the present invention records the loading material corresponding to the ID uniquely assigned to the vehicle-mounted device 21 used for toll collection, and based on this, the truck material is recorded. Since it is determined whether or not the unloading zone is correct, it is possible to carry out accurate truck unloading without incurring communication costs for information communication terminals, without incurring costs, and without relying on workers. .
