Description

The present invention relates to a transportation management system that includes a transportation vehicle that transports goods and an information processing device that is communicatively connected to the transportation vehicle.

At work sites where transport vehicles that transport materials such as earth and sand are in operation, transport vehicle management may be performed to understand the work status of the transport vehicles and improve their work efficiency. Patent Document 1 discloses a system for managing transport vehicles at work sites where transport vehicles and loading machines that load materials onto the transport vehicles are in operation. The system in Patent Document 1 includes a transport vehicle equipped with a transmitter that emits radio waves containing specific data that identifies the transport vehicle, and a loading machine equipped with a mobile terminal. The mobile terminal equipped on the loading machine receives radio waves from the transmitter and detects the strength of the received radio waves. The mobile terminal then identifies and manages transport vehicles approaching the loading machine based on the specific data contained in the received radio waves and the strength of the radio waves.

International Publication No. 2015/156018

However, the system in Patent Document 1 cannot identify the contents (type) of the goods being transported by the transport vehicle. For this reason, on-site workers (in most cases, the driver of the transport vehicle) manually record information indicating the contents (type) of the goods loaded by the loading machine. This manual work places a burden on on-site workers and can lead to recording errors or omissions. Therefore, there is a need for technology that can manage the contents of goods being transported by transport vehicles while reducing the workload of on-site workers.

The present invention provides a transportation management system that reduces the workload of on-site workers and enables management of the contents of items transported by transportation vehicles.

The transportation management system of the present invention comprises a first storage unit installed in an area where transported goods are stored and storing first information; a transport vehicle that transports the goods and acquires the first information stored in the first storage unit and transmits first code information corresponding to the acquired first information and identification information that identifies the transport vehicle; and an information processing device that receives the first code information and identification information transmitted by the transport vehicle and manages the contents of the goods transported by the transport vehicle based on the received first code information and identification information.

This invention reduces the workload of on-site workers and enables management of the contents of items being transported by transport vehicles.

Embodiments of the present invention will be described in detail with reference to the drawings. It goes without saying that in the following embodiments, the components (including element steps, etc.) are not necessarily essential unless specifically stated otherwise or considered to be clearly essential in principle.

Example 1
FIG. 1 is a diagram showing the overall configuration of a transportation management system 1 according to a first embodiment. The transportation management system 1 according to the first embodiment is a system for managing the work status of a transportation vehicle 110 that transports materials such as earth and sand. The transportation management system 1 includes a plurality of transmission devices 210-213 installed at a transportation site 100, one or more transportation vehicles 110, a cloud server 400, and an information display device 301. The transportation site 100 includes a loading area 201 where material A, which is a transportation material, is stored and where the material A is loaded onto the transportation vehicle 110, a loading area 202 where material B, which is a transportation material, is stored and where the material B is loaded onto the transportation vehicle 110, and a loading area 203 where material C, which is a transportation material, is stored and where the material C is loaded onto the transportation vehicle 110. The transportation site 100 also includes an unloading area 200 where the transportation material loaded onto the transportation vehicle 110 is unloaded. For example, the transport vehicle 110 loads material A in the loading area 201, moves to the unloading area 200, and unloads the material A loaded on the transport vehicle 110 in the unloading area 200.

(Transportation site 100)
A transmitting device 211 is installed in the loading area 201 to transmit information to the transport vehicles 110 near the loading area 201 and inside the loading area 201. The transmitting device 211 holds information indicating the loading area 201 and transmits a signal 211S indicating the loading area 201. A transmitting device 212 is installed in the loading area 202 to transmit information to the transport vehicles 110 near the loading area 202 and inside the loading area 202. The transmitting device 212 holds information indicating the loading area 202 and transmits a signal 212S indicating the loading area 202. A transmitting device 213 is installed in the loading area 203 to transmit information to the transport vehicles 110 near the loading area 203 and inside the loading area 203. The transmitting device 213 holds information indicating the loading area 203 and transmits a signal 213S indicating the loading area 203. Furthermore, in the unloading area 200, a transmitting device 210 is installed that transmits information to the transport vehicles 110 that are near the unloading area 200 and that have entered the unloading area 200. The transmitting device 210 holds information indicating the unloading area 200 and transmits a signal 210S indicating the unloading area 200. The information held by the transmitting devices 211 to 213 corresponds to the first information of the present invention. Furthermore, the information held by the transmitting device 210 corresponds to the second information of the present invention. The transmitting devices 210 to 213 output signals in accordance with wireless standards such as RFID, Wi-Fi, ZIGBEE (registered trademark), and BLUETOOTH (registered trademark).

In Example 1, the transmitting devices 210-213 output signals 210S-213S, but they do not need to have the function of outputting signals. The transmitting devices 210-213 do not need to be able to output information as long as they hold the information acquired by the transport vehicle 110. For example, the transmitting devices 210-213 may be displays that display two-dimensional barcodes or the like with embedded information. The transport vehicle 110 uses a camera to capture the two-dimensional barcode displayed on the display and acquires the information embedded in the two-dimensional barcode. The transmitting devices 211-213 installed in the loading areas 201-203 and the displays that display the two-dimensional barcodes or the like correspond to the first holding unit of the present invention. Furthermore, the transmitting device 210 and the display installed in the unloading area 200 correspond to the second holding unit of the present invention.

In addition, the information transmitted by transmitting devices 210-213 is not limited to information indicating the area, but may also be identification information that identifies transmitting devices 210-213 (for example, the IP address of the transmitting device, the MAC address of transmitting device 210, or information unique to the transmitting device). While transmitting devices 210-213 are installed in areas 200-203, the installation locations of transmitting devices 210-213 do not necessarily have to be inside areas 200-203. The unloading area 200 and loading areas 201-203 are referred to as areas 200-203. The installation locations of transmitting devices 210-213 may be outside areas 200-203, underground, or in the air, as long as the installation locations allow transport vehicles 110 approaching areas 200-203 to obtain information.

(Transport vehicle 110)
The transport vehicle 110 is a vehicle that carries and transports a load of transported goods. The transport vehicle 110 is, for example, a wheel loader, a truck, or a shovel. The transport vehicle 110 has a receiving device 111, an encoding device 112, and a control unit 113. The receiving device 111 is a device that receives signals output by the transmitting devices 210 to 213, and the encoding device 112 is a device that encodes the signals received by the receiving device 111. The encoding device 112 has a signal code conversion table 114 for converting the received signals into code information.

Figure 2 is a diagram showing the signal code conversion table 114. The signal code conversion table 114 is a table in which the signals 210S to 213S output by the transmitting devices 210 to 213 are stored in association with code information. The encoding device 112 converts the signals output from the transmitting devices 210 to 213 into code information and outputs it by referring to the signal code conversion table 114. For example, when the encoding device 112 receives the signal 210S output by the transmitting device 210, it refers to the signal code conversion table 114 and outputs code information (0x00) indicating the unloading area 200 in which the transmitting device 210 is installed. The code information output by the transmitting devices 211 to 213 corresponds to the first code information of the present invention, and the code information output by the transmitting device 210 corresponds to the second code information of the present invention.

The control unit 113 of the transport vehicle 110 controls the operation of each unit of the transport vehicle 110. The control unit 113 receives code information from the encoding device 112 and transmits the received code information to the cloud server 400 along with the vehicle PIN, load information, and time. The vehicle PIN is identification information for identifying the transport vehicle 110. The load information is information indicating the weight of the goods loaded on the transport vehicle 110. Note that the load information may also be the weight of the transport vehicle 110 including the loaded goods. The time is information indicating the current time output by an RTC (real-time clock). The RTC is incorporated into the processor 131 (see Figure 3), which will be described later.

Figure 3 is a hardware block diagram of the control unit 113 of the transport vehicle 110. As shown in Figure 3, the control unit 113 has a processor 131, a communication interface 132 (hereinafter, interface will be abbreviated as I/F), a main memory device 133, an auxiliary memory device 134, an input/output I/F 135, and a bus 136 that communicatively connects the above-mentioned modules. The input/output I/F 135 is connected to the encoding device 112 and a monitor (not shown). The processor 131 is a central processing unit. The processor 131 is, for example, a CPU (Central Processing Unit), a DSP (Digital Signal Processor), an ASIC (Application Specific Integrated Circuit), etc. The processor 131 has an RTC that outputs the current time. The processor 131 expands and executes programs stored in the auxiliary memory device 134 in the working area of the main memory device 133. The main memory device 133 stores programs executed by the processor 131, data processed by the processor, etc. The main memory device 133 is a flash memory, RAM (Random Access Memory), ROM (Read Only Memory), etc. The auxiliary memory device 134 stores the vehicle PIN, load information, etc. The auxiliary memory device 134 is a hard disk drive (HDD), solid state drive (SSD), etc. The communication I/F 132 transmits the vehicle PIN and load information stored in the auxiliary memory device 134, the time output by the RTC, and the code information encoded by the encoding device 112 to the cloud server 400. Information including the vehicle PIN, load information, code information, and time is called vehicle information. The communication I/F 132 transmits the vehicle information to the cloud server 400 periodically or in response to a request from the cloud server 400.

(Cloud server 400)
1 , the cloud server 400 is communicatively connected to one or more haulage vehicles 110, and receives and manages vehicle information transmitted from each haulage vehicle 110. The cloud server 400 corresponds to the information processing device of the present invention. The cloud server 400 is communicatively connected to the information display device 301, and transmits generated information to the information display device 301 in response to a request from the information display device 301.

The cloud server 400 includes an information processing unit 401 and a memory unit 410. The information processing unit 401 processes vehicle information received from the haulage vehicle 110 and generates and manages information such as the operation status 701 of the haulage vehicle 110, the unloading record 702 of the haulage vehicle 110, and the unloading record by material 703 (see Figure 7). The information processing unit 401 then transmits the information it manages, such as the operation status 701 of the haulage vehicle 110, the unloading record 702 of the haulage vehicle 110, and the unloading record by material 703, to the information display device 301.

Figure 4 is a hardware block diagram of the information processing unit 401 of the cloud server 400. As shown in Figure 4, the information processing unit 401 has a processor 431, a communication I/F 432, a main memory device 433, an auxiliary memory device 434, an input/output I/F 435, and a bus 436. Since each component of the information processing unit 401 is similar to each component of the control unit 113, their description will be omitted as appropriate. The communication I/F 432 receives vehicle information from the haulage vehicle 110, and the processor 431 stores the vehicle information received from the communication I/F 432 in the memory unit 410 via the input/output I/F 435. The processor 431 acquires the vehicle information from the memory unit 410 via the input/output I/F 435, and generates and manages information such as the operating status 701 of the haulage vehicle 110, the unloading record 702 of the haulage vehicle 110, and the unloading record by material 703. Then, in response to a request from the information display device 301, the communication I/F 432 transmits information such as the operating status 701 of the transport vehicle 110 it manages, the unloading record 702 of the transport vehicle 110, and the unloading record by material 703 to the information display device 301.

The storage unit 410 is one or more HDDs, SSDs, etc., and stores various information including vehicle information collected by the cloud server 400, as well as programs executed by the processor of the information processing unit 401. As shown in Figure 1, the storage unit 410 in Example 1 stores a cord material comparison table 411, a cord storage area 412, a status determination table 413, and an information accumulation area 414.

Figure 5 is a diagram showing the code material comparison table 411. The code material comparison table 411 is used to output the contents (type of material) of the goods being transported by the transport vehicle 110 from the code information. The code material comparison table 411 is a table that stores code information corresponding to the signals output by the transmitting devices 211-213, in association with the types of materials managed in the loading areas where those transmitting devices 211-213 are installed. The information processing unit 401 references the code material comparison table 411 and outputs the contents (type of material) of the goods being transported by the transport vehicle 110 from the received code information.

Figure 6 is a diagram showing the status determination table 413. The status determination table 413 is used to identify the status of the transport vehicle 110 from the load information and received code information. The status determination table 413 stores the load status, received code, held code, and status of the transport vehicle 110 in association with each other. The information processing unit 401 references the status determination table 413 and outputs the status of the transport vehicle 110 based on the load status, received code, and held code.

The loading status in Figure 6 is information indicating the loading status of transported goods that can be loaded onto the transport vehicle 110. Specifically, it is either information indicating an "empty" state in which the transport vehicle 110 is not carrying any transported goods, or information indicating a "laden" state in which the transport vehicle 110 is carrying any transported goods. The loading status is determined by the load information received from the transport vehicle 110. For example, if the weight indicated by the load information is smaller than a threshold value, the loading status is an "empty" state, and if the weight indicated by the load information is greater than the threshold value, the loading status is a "laden" state.

The received code in Figure 6 is code information received from the transport vehicle 110. The held code is code information held in the code holding area 412, and is code information received immediately before the code information received from the transport vehicle 110.

The transport vehicle status in Figure 6 is information indicating the status of the transport vehicle 110. If the received code and the retained code are the same, the position of the transport vehicle 110 has not changed, and the transport vehicle's status is determined to be stagnant. If the received code and the retained code are different, the transport vehicle's status is determined to have entered the area indicated by the received code. For example, if the received code is code information (0x00) corresponding to the signal output by the transmitter 210 in the unloading area 200, and the retained code is not code information (0x00), the transport vehicle's status is determined to have entered the unloading area 200. If the received code is code information (0x01, 0x10, 0x11) corresponding to the loading areas 201-203, and the retained code is code information different from the received code, the transport vehicle's status is determined to have entered the loading area 201-203 indicated by the received code.

The information processing unit 401 references the status determination table 413 and outputs the status of the transport vehicle from the above-mentioned loading status ('empty' status, 'loaded' status), received code, and held code.

The code storage area 412 is an area that stores past code information received from the transport vehicle 110 as a stored code. The code storage area 412 stores time, vehicle PIN, and code information in association with each other.

The information storage area 414 stores the time, code information, vehicle PIN, load information, loading status, transport vehicle status, and materials in association with each other. The time, code information, vehicle PIN, and load information are information received from the transport vehicle 110. The loading status is the loading status shown in Figure 6, and the transport vehicle status is the status of the transport vehicle shown in Figure 6. The materials are information output by referring to the code material comparison table 411.

The information processing unit 401 outputs the operation status 701 of the transport vehicle 110, the unloading record 702 of the transport vehicle 110, and the unloading record by material 703 shown in FIG. 7 based on the information stored in the information storage area 414. The information processing unit 401 outputs the operation status 701 of the transport vehicle 110 based on the time, vehicle PIN, and loading status stored in the information storage area 414. The operation status 701 of the transport vehicle is information with the horizontal axis representing time and the vertical axis representing the loading status. The loading status is either an "empty" state in which the transport vehicle 110 is not loaded with transported goods, or a "loaded" state in which the transport vehicle 110 is loaded with transported goods.

The information processing unit 401 also outputs the unloading record 702 of the transport vehicle 110 based on the time, vehicle PIN, transport vehicle status, and load information stored in the information storage area 414. The unloading record 702 of the transport vehicle is information with the horizontal axis representing the time and the vertical axis representing the weight of the transported goods. For example, the weight of the transported goods is calculated from the difference between the load information of the transport vehicle that entered the unloading area and the load information immediately thereafter.

The information processing unit 401 also outputs unloading results 703 by material based on the transport vehicle status, load information, and materials stored in the information storage area 414. The unloading results 703 by material is information with the horizontal axis representing the material and the vertical axis representing the weight of the unloaded material. For example, the weight of the unloaded material is calculated from the difference between the load information of the transport vehicle that entered the unloading area and is transporting the material, and the load information immediately thereafter. The weight of the material in (c) of Figure 7 may be the weight of the material unloaded by a single transport vehicle 110, or it may be the total weight of the material unloaded by multiple transport vehicles 110 at the transport site 100.

(Information display device 301)
An information display device 301 is installed in a control room 300 of the transportation site 100. The information display device 301 is, for example, a personal computer, a smartphone, or a tablet. The location where the information display device 301 is installed is not limited to the control room 300, but may also be a control center that comprehensively manages information about the transportation vehicles 110, or may be at the transportation site 100 outside the control room 300. The information display device 301 transmits a request for information to the cloud server 400, receives information generated by the cloud server 400 as a response to the request, and displays it.

The information display device 301 displays various information based on the information received from the cloud server 400. Specifically, the information display device 301 displays the contents of the goods being transported by the transport vehicle 110 based on the information received from the cloud server 400.

Figure 7 is a diagram showing information displayed by the information display device 301. As shown in Figure 7 (a), the information display device 301 displays the operation status 701 of the transport vehicle 110. From the operation status 701 of the transport vehicle 110, the user of the information display device 301 can check the loading status of each transport vehicle 110 in chronological order for each transport vehicle 110.

In addition, the information display device 301 displays the unloading record 702 of the transport vehicle 110, as shown in (b) of Figure 7. From the unloading record 702 of the transport vehicle 110, the user of the information display device 301 can check the weight of the transported goods unloaded by the transport vehicle 110 in chronological order for each transport vehicle 110.

In addition, the information display device 301 displays unloading records by material 703, as shown in Figure 7(c). From the unloading records by material 703, the user of the information display device 301 can check the weight of materials unloaded in the unloading area 200 by material.

(Operation of the transportation management system)
FIG. 8 is a diagram illustrating the operation of the transportation management system 1. The operation of the transportation management system 1 will be described with reference to FIG. 8. When the transportation vehicle 110 enters the loading area 201, the receiving device 111 receives a signal 211S output by the transmitting device 211. The receiving device 111 transmits the received signal 211S to the encoding device 112. The encoding device 112 converts the signal 211S into code information (e.g., 0x01) by referring to the signal code conversion table 114, and transmits the code information to the control unit 113. The control unit 113 acquires the vehicle PIN, time, and load information, and transmits the vehicle PIN, time, and load information together with the code information to the cloud server 400. The same operation occurs when the transportation vehicle 110 enters the other loading areas 202 and 203, so a description thereof will be omitted.

When the transport vehicle 110 enters the unloading area 200, the receiving device 111 receives the signal 210S output by the transmitting device 210. The receiving device 111 transmits the received signal 210S to the encoding device 112. The encoding device 112 converts the signal 210S into code information (e.g., 0x00) by referring to the signal code conversion table 114, and transmits it to the control unit 113. The control unit 113 transmits the vehicle PIN, time, and load information along with the code information to the cloud server 400.

The communication I/F 432 of the cloud server 400 receives the vehicle information (code information, vehicle PIN, time, and load information) sent by the control unit 113. The processor 431 of the information processing unit 401 stores the received vehicle information in the information storage area 414. The processor 431 also references the code material comparison table 411 to output materials from the received code information and stores them in the information storage area 414. The processor 431 also stores the loading status ('empty' status, 'loaded' status) determined based on the load information and the status of the transport vehicle output based on the status determination table 413 in the information storage area 414. The processor 431 then associates the received code information with the vehicle PIN and time and stores it as a stored code in the code storage area 412.

The communication I/F 432 receives a request from the information display device 301 and, as a response to the request, transmits to the information display device 301 the operation status 701 of the haulage vehicle 110, the unloading record 702 of the haulage vehicle 110, or the unloading record by material 703, all of which are shown in FIG. 7. When the communication I/F 432 receives a request from the information display device 301, the processor 431 generates information such as the operation status 701 of the haulage vehicle 110, the unloading record 702 of the haulage vehicle 110, and the unloading record by material 703. The communication I/F 432 then transmits the generated information such as the operation status 701 of the haulage vehicle 110, the unloading record 702 of the haulage vehicle 110, and the unloading record by material 703, to the information display device 301.

(Operation flow of the receiving device 111)
9 is a flowchart showing the operation performed by the receiving device 111 of the haulage vehicle 110. As shown in FIG. 9, when the receiving device 111 of the haulage vehicle 110 receives a signal from the transmitting devices 210 to 213 (V101: Yes), it transmits the received signal to the encoding device 112 (V102). The receiving device 111 determines whether or not a signal has been received from the transmitting devices 210 to 213 at a predetermined sampling period (V101). If no signal has been received from the transmitting devices 210 to 213 (V101: No), this flow ends. Then, this flow is executed again at the next sampling period.

(Operation flow of the encoding device 112)
FIG. 10 is a flowchart showing the operation performed by the encoding device 112 of the transport vehicle 110. As shown in FIG. 10, the encoding device 112 determines whether or not a signal has been received from the receiving device 111 (V201). If it is determined that a signal has been received from the receiving device 111 (V201: Yes), the encoding device 112 refers to the signal code conversion table 114 (see FIG. 2) and converts the received signal into code information (V202). The encoding device 112 then transmits the code information to the control unit 113 (V203). If a signal has not been received from the receiving device 111 (V201: No), the encoding device 112 performs the determination of V201 again after a predetermined time has elapsed.

(Operation flow of the control unit 113)
11 is a flowchart showing the operation executed by the control unit 113 of the transport vehicle 110. As shown in FIG. 11 , the processor 131 of the control unit 113 determines whether or not code information has been received from the encoding device 112 (V301). If it is determined that code information has been received from the encoding device 112 (V301: Yes), the processor 131 acquires the vehicle PIN, load information, and time (V302). Then, the processor 131 transmits the vehicle information (code information, vehicle PIN, load information, and time) to the cloud server 400 via the communication I/F 132 (V303). If code information has not been received from the encoding device 112 (V301: No), the processor 131 performs the determination of V301 again after a predetermined time has elapsed.

(Information processing flow by cloud server 400)
12 is a flowchart showing the information processing operation executed by the processor 431 of the cloud server 400. The information processing operation executed by the processor 431 will be described in detail with reference to FIG. 12. The processor 431 receives vehicle information (code information, vehicle PIN, load information, and time) transmitted from the transport vehicle 110 via the communication I/F 432 (C101). Next, the processor 431 reads the stored code (the code information received immediately before the received code information) from the code storage area 412 (C102). The processor 431 also reads the cord material comparison table 411 from the storage unit 410 (C103) and the status determination table 413 from the storage unit 410 (C104).

Next, the information processing unit 401 refers to the status determination table 413 to determine the status of the transport vehicle 110 (C105). If it is determined that the transport vehicle 110 entered the loading area empty, the process proceeds to C106. On the other hand, if it is determined that the transport vehicle 110 entered the unloading area 200 loaded, the process proceeds to C107. If it is determined that the transport vehicle 110 entered the loading area empty, the processor 431 refers to the code material comparison table 411 that was read and acquires the material corresponding to the received code (C107). The processor 431 then stores the acquired material as loading information in the information storage area 414 of the memory unit 410 (C108). From the vehicle PIN, time, and loading information stored in the information storage area 414, it is possible to determine the time the transported goods were loaded, the transport vehicle 110 on which the goods were loaded, and the material of the goods.

If it is determined that the transport vehicle 110 has entered the unloading area 200 while loaded, the processor 431 acquires the material corresponding to the retention code (C107). The processor 431 then stores the acquired material as unloading information in the information storage area 414 of the memory unit 410 (C109). From the vehicle PIN, time, load information, and unloading information stored in the information storage area 414, it is possible to determine the time to unload the transported goods, the transport vehicle 110 that will unload the transported goods, the material of the transported goods, and the weight of the transported goods to be unloaded.

(Information output flow by cloud server 400)
FIG. 13 is a flowchart showing the information output operation executed by the processor 431 of the cloud server 400. The information output operation by the information processing unit 401 will be described in detail with reference to FIG. 13 . First, the processor 431 determines whether a request has been received from the information display device 301 in the management room 300 via the communication I/F 432 (C201). If it is determined that a request has been received (C201: Yes), the processor 431 collects necessary information from the information storage area 414 and generates information to be transmitted to the information display device 301 (C202). Then, the processor 431 outputs the generated information via the communication I/F 432 (C203). The information output by the information processing unit 401 includes the operation status 701 of the transport vehicle 110, the unloading record 702 of the transport vehicle 110, and the unloading record by material 703, all of which are shown in FIG. 7 .

As shown in FIG. 7, the information display device 301 uses information received from the cloud server 400 to display the operating status 701 of the transport vehicle 110, the unloading record 702 of the transport vehicle 110, and the unloading record by material 703.

(Effects of Example 1)
The cloud server 400 can refer to the code material comparison table 411 and manage the contents (materials) of the goods being transported by the transport vehicle based on the code information and vehicle PIN received from the transport vehicle 110. This eliminates the need for on-site workers (especially the driver of the transport vehicle 110) to manually manage the contents of the goods, thereby reducing manual management errors and the workload of on-site workers.

In addition, since the cloud server 400 stores the code material comparison table 411, the contents of the items transported by the transport vehicle 110 can be centrally managed on the cloud server 400.

By providing transmitters 210-213 at the transport site 100 and a receiver 111 on the transport vehicle 110, code information can be obtained simply by the transport vehicle 110 approaching areas 200-203. This reduces the workload of on-site workers.

The cloud server 400 can output the loading status ('empty' status, 'laden' status) based on the load information received from the transport vehicle 110. This allows the loading status of the transport vehicle to be grasped and instructions given to the transport vehicle in the 'empty' status, making it possible for the transport vehicle to work efficiently.

The cloud server 400 can manage the status of the transport vehicle 110 (see Figure 6) based on the received code and stored code corresponding to the code information received from the transport vehicle 110. This allows the user to know the location of the transport vehicle 110 and whether the transport vehicle 110 is stalled. As a result, it is possible to give instructions to stalled transport vehicles 110, etc., and to have idle transport vehicles work efficiently.

The user of the information display device 301 can check the displayed operation status 701 of the transport vehicle, the unloading record of the transport vehicle 702, and the unloading record by material 703. By checking the operation status 701 of the transport vehicle, the user can understand the loading status over time. Furthermore, by checking the unloading record 702 of the transport vehicle, the user can understand the unloading record over time. Furthermore, by checking the unloading record by material 703, the user can understand the unloading progress and volume for each material.

By installing transmitters 210-213 in both the loading areas 201-203 and the unloading area 200, it is possible to manage both the materials loaded in the loading areas 201-203 and the materials unloaded in the unloading area 200.

Example 2
In the first embodiment, an example has been described in which the transport vehicle 110 installs transmitting devices 210 to 213 in the loading areas 201 to 203 and the unloading area 200 at the transport site 100, and manages the unloading record of the transport vehicle 110. In the second embodiment, not only the unloading record of the transport vehicle 110 but also the shipping record of the shipping vehicle 510 is managed.

Figure 14 is a diagram showing the overall configuration of a transportation management system 2 of Example 2. In addition to the configuration of Example 1, Example 2 includes a transmitting device 601 installed in a shipping vehicle 510 at a transportation site 500, and a receiving/processing device 611 installed on the shipping route along which the shipping vehicle 510 travels. The receiving/processing device 611 corresponds to the transmitting/receiving device of the present invention. The receiving/processing device 611 receives and processes the signal output by the transmitting device 601. Similarly to Example 1, the transportation management system 2 of Example 2 also includes a cloud server 400 having a memory unit 410 and an information processing unit 401, and an information display device 301 installed in a management room 300.

The transmitting device 601 of the shipping vehicle 510 outputs identification information, load information, and time for identifying the shipping vehicle 510. The receiving processing device 611 receives and processes the information output by the transmitting device 601. The receiving processing device 611 transmits the processed information to the cloud server 400. The cloud server 400 stores the identification information, load information, and time for identifying the shipping vehicle 510 received from the receiving processing device 611 in the memory unit 410.

15 is a diagram showing information displayed by the information display device 301 of Example 2. The cloud server 400 generates a shipping record for the shipping vehicle 510 based on the identification information for identifying the shipping vehicle 510, the load information, and the time stored in the memory unit 410. The information display device 301 installed in the management room 300 sends a request to the cloud server 400 in response to a user instruction or periodically, and the cloud server 400 sends information indicating the shipping record to the information display device 301 in response to the request. As shown in FIG. 15, the information display device 301 displays a shipping record 801 for the shipping vehicle based on the information received from the cloud server 400. The shipping record 801 for the shipping vehicle is information in which the horizontal axis represents time and the vertical axis represents the weight of the transported goods. The weight of the transported goods is calculated from the load information. The user of the information display device 301 can check the weight of the transported goods shipped by the shipping vehicle 510 in chronological order from the displayed shipping record 801 for the shipping vehicle 510.

The cloud server 400 of Example 2 is also capable of generating shipping records by material. The cloud server 400 stores a table that associates the identification information of the shipping vehicle 510 with the material of the transported item transported by this shipping vehicle 510. The cloud server 400 references this table and converts the identification information received from the reception processing device 611 into the material of the transported item. The cloud server 400 then generates shipping records by material based on the converted material of the transported item, load information, and time. The information display device 301 displays shipping records by material (not shown) based on information indicating shipping records by material received from the cloud server 400.

(Effects of Example 2)
A user of the information display device 301 according to the second embodiment can check the weight of the shipped goods in chronological order from the shipping record 801 of the shipping vehicle 510 .

A user of the information display device 301 in Example 2 can check the weight of the shipped goods for each material from the shipping record by material. Other effects are the same as in Example 1.
