[0016] [Figure 1] 1 is a block diagram showing the overall configuration of a construction vehicle operation management system according to an embodiment of the present invention; [Figure 2] 1 is a block diagram showing the configuration of a construction vehicle operation management system according to an embodiment of the present invention; [Figure 3] FIG. 2 is a schematic diagram showing operation management information according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0017] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1, the construction vehicle operation management systems A1 to An according to this embodiment are provided on first to n-th construction vehicles M1 to Mn, respectively, which are a plurality (n vehicles), where "n" is a natural number of 2 or more.

[0018] The first construction vehicle M1 is provided with a first construction vehicle operation management system A1 equipped with a first vehicle communication terminal T1, a first head-up display H1, and a first voice generating device K1. The second construction vehicle M2 is provided with a second construction vehicle operation management system A2 equipped with a second vehicle communication terminal T2, a second head-up display H2, and a second voice generating device K2. (Omitted) The nth construction vehicle Mn is provided with an nth construction vehicle operation management system An equipped with an nth vehicle communication terminal Tn, an nth head-up display Hn, and an nth voice generating device Kn.

[0019] In the following description, the first to nth construction vehicle operation management systems A1 to An will be collectively referred to as the construction vehicle operation management system A. The first to nth construction vehicles M1 to Mn will be collectively referred to as the construction vehicle M. The first to nth vehicle communication terminals T1 to Tn will be collectively referred to as the vehicle communication terminal T.

[0020] Furthermore, when the first to n-th head-up displays H1 to Hn are collectively referred to, they will be referred to as head-up displays H. Furthermore, when the first to n-th sound producing devices K1 to Kn are collectively referred to, they will be referred to as sound producing devices K.

[0021] As shown in the figure, the construction vehicle operation control system A is connected to the operation information server B via a communication line N. That is, the construction vehicle operation control system A communicates with the operation information server B via the communication line N. The operation information server B transmits (provides) information necessary for operation control of the construction vehicle M to the construction vehicle operation control system A via the communication line N.

[0022] The construction vehicle M is a vehicle operated at a construction site, and is a dump truck that is loaded with construction materials and travels on the construction site and on public roads outside the construction site. In other words, the construction vehicle M is a transport vehicle that is driven by a driver and travels on the construction site and on public roads outside the construction site.

[0023] In the first construction vehicle operation management system A1, the first vehicle communication terminal T1 is connected to a communication line N. In addition, the first vehicle communication terminal T1 is electrically connected to a first head-up display H1 and a first voice generating device K1 separately from the communication line N.

[0024] In the second construction vehicle operation management system A2, the second vehicle communication terminal T2 is connected to the communication line N. The second vehicle communication terminal T2 is also electrically connected to a second head-up display H2 and a second voice generating device K2 separately from the communication line N.

[0025] In the nth construction vehicle operation management system An, the nth vehicle communication terminal Tn is connected to the communication line N. The nth vehicle communication terminal Tn is also electrically connected to the nth head-up display Hn and the nth voice generating device Kn separately from the communication line N.

[0026] The vehicle communication terminal T corresponds to the traffic management device of the present invention and is, for example, a well-known smartphone or tablet terminal. The vehicle communication terminal T is equipped with a construction vehicle traffic management program as one of its application programs, and functions as a traffic management device when the construction vehicle traffic management program is activated.

[0027] That is, the vehicle communication terminal T is an operation management device that manages the operation of the construction vehicle M by outputting operation management information required by the driver of the construction vehicle M to the head-up display H and the voice generating device K. This operation management information is, for example, as follows:

[0028] (1) Travel speed of construction vehicle M and estimated arrival time at destination (2) Navigation information (displaying right and left turns, etc. according to the registered transportation route) (3) Instructions from the operation manager (such as instructions for one-way traffic or detour routes) (4) Driving rule violation warnings (speeding, sudden braking, route deviation, etc.) (5) Caution points along the transportation route and warnings to be careful when passing through such points

[0029] The vehicle communication terminal T generates operation management information based on the basic operation management information input, for example, when the construction vehicle M starts operating, but as necessary, refers to additional operation management information acquired from the operation information server B. This additional operation management information is information acquired by the operations manager after the construction vehicle M starts operating (when it starts traveling), and is information necessary for the operation management of the construction vehicle M.

[0030] Such a vehicle communication terminal T has the detailed configuration shown in Fig. 2. That is, the vehicle communication terminal T has a first communication unit 1, a second communication unit 2, an operation unit 3, a memory unit 4, a display unit 5, and a calculation unit 6. The first communication unit 1 is electrically connected to an external communication line N, and is also electrically connected to the calculation unit 6. This first communication unit 1 receives operation management information from the operation information server B via the communication line N and outputs the information to the calculation unit 6.

[0031] The second communication unit 2 is electrically connected to the head-up display H and the voice generating device K, and is also electrically connected to the calculation unit 6. The second communication unit 2 transmits the driving control information input from the calculation unit 6 to the head-up display H and the voice generating device K.

[0032] Here, the wireless communication between the second communication unit 2 and the head-up display H and the voice generating device K is a method different from the wireless communication between the first communication unit 1 and the operation information server B via the communication line N. If the vehicle communication terminal T is a smartphone or a tablet terminal, the communication line N is a mobile phone network (telephone line).

[0033] In contrast, the wireless communication between the second communication unit 2 and the head-up display H and the voice generating device K is different from the communication method of the mobile phone network, and is, for example, a short-range communication method such as Bluetooth (registered trademark) or a wireless LAN (Local Area Network) method.

[0034] The operation unit 3 is composed of a keyboard, a mouse, etc., and is electrically connected to the calculation unit 6. The operation unit 3 receives operation instructions input by the driver of the construction vehicle M and outputs them to the calculation unit 6. The operation instructions are, for example, instructions to display operation management information on the head-up display H.

[0035] The memory unit 4 is made up of multiple storage devices such as a ROM (Read Only Memory), a RAM (Random Access Memory), and a hard disk, and is electrically connected to the calculation unit 6. This memory unit 4 stores the above-mentioned construction vehicle operation management program in advance and also temporarily stores operation management information.

[0036] The display unit 5 is, for example, a liquid crystal display device, and is electrically connected to the calculation unit 6. The display unit 5 displays the operation control information input from the calculation unit 4 and operational instructions for the driver.

[0037] The calculation unit 6 is equipped with a CPU and an input / output circuit, and is electrically connected to the first communication unit 1, the second communication unit 2, the operation unit 3, the memory unit 4, and the display unit 5. The calculation unit 6 reads out a construction vehicle operation control program (application program) from the memory unit 4, and executes the construction vehicle operation control program on a predetermined OS (Operating System: basic software).

[0038] This calculation unit 6 controls the first communication unit 1, the second communication unit 2, the operation unit 3, the memory unit 4 and the display unit 5 based on the construction vehicle operation management program, thereby causing the first communication unit 1 to acquire operation management information and transmit the operation management information to the second communication unit 2.

[0039] The head-up display H is a display device that displays (projects) a traffic control image G on the windshield W of the construction vehicle M, as shown in Fig. 3. That is, the head-up display H converts traffic control information input from the vehicle communication terminal T into a two-dimensional image, the traffic control image G, and displays it on the windshield W, thereby visually providing the driver with the traffic control information.

[0040] The voice generating device K is a device that outputs the operation control information as sound. That is, the voice generating device K is equipped with a speaker, and converts the operation control information received from the second communication unit 2 of the vehicle communication terminal T into a sound signal and outputs it to the speaker, thereby providing the operation control information to the driver audibly.

[0041] Next, the operation of the first to n-th construction vehicle operation management systems A1 to An according to this embodiment will be described in detail with reference to FIG.

[0042] In the first to n-th construction vehicle operation management systems A1 to An, the first to n-th vehicle communication terminals T1 to Mn provided in the first to n-th construction vehicles M1 to Mn, respectively, output operation management information corresponding to the first to n-th construction vehicles M1 to Mn to the first to n-th head-up displays H1 to Hn, respectively.The first to n-th head-up displays H1 to Hn then display the operation management information corresponding to the first to n-th construction vehicles M1 to Mn as an operation management image G on the windshield W.

[0043] For example, the first vehicle communication terminal T1 provided on the first construction vehicle M1 outputs traffic control information corresponding to the first construction vehicle M1 to the first head-up display H1. Then, the first head-up display H1 displays a traffic control image G required by the driver of the first construction vehicle M1 on the windshield W of the first construction vehicle M1 based on the traffic control information corresponding to the first construction vehicle M1.

[0044] Furthermore, the second vehicle communication terminal T2 provided on the second construction vehicle M2 outputs operation control information corresponding to the second construction vehicle M2 to the second head-up display H2. Then, the second head-up display H2 displays an operation control image G required by the driver of the second construction vehicle M2 on the windshield W of the second construction vehicle M2 based on the operation control information corresponding to the second construction vehicle M2.

[0045] (Omitted) The nth vehicle communication terminal Tn provided on the nth construction vehicle Mn outputs operation control information corresponding to the nth construction vehicle Mn to the nth head-up display Hn. Then, the nth head-up display Hn displays an operation control image G required by the driver of the nth construction vehicle Mn on the windshield W of the nth construction vehicle Mn based on the operation control information corresponding to the nth construction vehicle Mn.

[0046] Here, the traffic control information is used to manage the transportation work performed by each of the first to nth construction vehicles M1 to Mn, i.e., the travel of the first to nth construction vehicles M1 to Mn at the construction site, and as described above, includes the travel speed of the construction vehicle M and the estimated time of arrival at the destination, etc. A traffic control image G based on such traffic control information is displayed for the driver on the windshield W of each of the first to nth construction vehicles M1 to Mn, and

[0047] That is, the construction vehicle operation management system A of this embodiment comprises a vehicle communication terminal T (operation management device) installed on a construction vehicle M that is subject to operation management, and a head-up display H installed on the construction vehicle M that displays an operation management image G on the windshield W based on operation management information acquired from the vehicle communication terminal T (operation management device).

[0048] According to this embodiment, it is possible to provide a construction vehicle operation control system A that makes it easy to acquire and understand operation control information. Therefore, according to this embodiment, it is possible to visually convey operation control information to the driver of the construction vehicle M, thereby contributing to improved safety and smooth operation of the construction vehicle M.

[0049] Furthermore, the construction vehicle operation control system A according to this embodiment further includes a voice output device that outputs the operation control information as sound. According to this embodiment, the operation control information is provided to the driver not only as a visual operation control image G but also as an auditory sound, making it even easier for the driver of the construction vehicle M to obtain and understand the operation control information.

[0050] Furthermore, in the construction vehicle operation management system A according to this embodiment, the operation management information is the traveling speed and estimated time of arrival at the destination of the construction vehicle M. According to this embodiment, the driver can easily and accurately grasp the traveling speed and estimated time of arrival at the destination of the construction vehicle M.

[0051] In the construction vehicle operation management system A according to this embodiment, the operation management information is navigation information. According to this embodiment, the driver can easily and accurately grasp the travel route of the construction vehicle M.

[0052] In the construction vehicle operation management system A according to this embodiment, the operation management information is instructions from the operation manager. According to this embodiment, the driver can easily and accurately understand the instructions from the operation manager.
