[0028] The vehicle-mounted control unit 40 includes a computer system. The communicator 43 is coupled to the vehicle-mounted control unit 40. The communicator 43 performs wireless communication with the management server 8. Vehicle-mounted control unit

[0029] Fig. Figure 4 is a block diagram illustrating a vehicle-mounted control unit 40 according to the embodiment. Both the management server 8 and the vehicle-mounted control unit 40 include a computer system. The vehicle-mounted control unit 40 includes a processor 48, such as a central processing unit (CPU), main memory 49, which includes non-volatile memory such as read-only memory (ROM) and volatile memory such as random-access memory (RAM), a data memory 50, and an interface 51, which includes an input / output circuit. Functions of the vehicle-mounted control unit 40 are stored as a computer program in the data memory 50. The processor 48 reads the computer program from the data memory 50, loads the computer program into the main memory 49, and performs the processing according to the computer program.It should be noted that the computer program can be distributed to the management server 8 via a network.

[0030] Similarly, the management server 8 includes a processor, main memory, data storage, and an interface.

[0031] The processor 48 includes an operating command receiving unit 48A, a control command output unit 48B, an operating data processing unit 48C, an image data processing unit 48D and a lighting control unit 48E.

[0032] The control command receiver 48A receives a remote control command transmitted by the information terminal 5. The control command output unit 48B issues a control command to control the excavator 2A based on the remote control command received by the control command receiver 48A. The control command output unit 48B issues a control command to cause at least one of the rotary head 9, the travel head 10, and the working attachment 11 to operate based on the remote control command received by the control command receiver 48A.

[0033] The operational data processing unit 48C collects operational data from excavator 2A. The operational data collected by operational data processing unit 48C is stored in data storage 50. Operational data processing unit 48C transmits the operational data of excavator 2A stored in data storage 50 to the management server 8.

[0034] The operating data of excavator 2A includes its operating time and location. The operating time includes the operating time of excavator 2A's electric motor 35. The operating data also includes the amount of electrical power consumed by electric motor 35. Furthermore, the operating data includes anomaly data, specifically the nature, location, and time of anomaly occurrence. Excavator 2A is equipped with a variety of sensors that record the operating data. Examples of these sensors include a motor sensor that records the operating time of electric motor 35 and a location sensor that records the excavator 2A's operating location.The position sensor can include a global navigation satellite system (GNSS) receiver, which uses GNSS to determine the absolute location of excavator 2A. The 48C operational data processing unit can collect the operational data of excavator 2A by retrieving the sensor's acquisition data.

[0035] The image data processing unit 48D retrieves image data of the area surrounding the rotating body 9, captured by camera 74. The image data retrieved by the image data processing unit 48D is stored in data storage 50. The image data processing unit 48D then transmits the image data of the area surrounding the excavator 2A, stored in data storage 50, to the management server 8.

[0036] The lighting control unit 48E controls the luminaire 75. The lighting control unit 48E determines the lighting conditions of the luminaire 75, including the lighting start time, lighting duration, and lighting end time. The lighting control unit 48E controls the luminaire 75 based on these defined lighting conditions. If the moving object in the vicinity of the excavator 2A is a person, and at least one section of the excavator 2A is equipped with a person sensor (infrared sensor), the lighting control unit 48E also controls the luminaire 75 so that the person in the vicinity of the excavator 2A is illuminated with automatic tracking lighting based on the detection data from the person sensor. Base station

[0037] Fig. Figure 5 is a left-hand view illustrating a section of excavator 2A according to the embodiment. As shown in Fig. As illustrated in Figure 5, the rotating body 9 includes a vehicle body frame 9A and an upper cover 9B arranged on an upper section of the vehicle body frame 9A. A working device 11 is coupled to a front section of the vehicle body frame 9A. The upper cover 9B is arranged to cover an opening provided on an upper section of the vehicle body frame 9A. The upper cover 9B is opened and closed by actuating the actuator.

[0038] Fig. 6 and Fig. Figure 7 is a diagram describing the operation of the excavator 2A according to the embodiment. When the base station 73 is not in use, it is housed inside the rotating body 9. When the base station 73 is housed inside the rotating body 9, the upper cover 9B is closed. As shown in Fig. As illustrated in Figure 6, the upper cover 9B is opened by the control command output unit 48B when the base station 73 is used. After the upper cover 9B is opened, the control command output unit 48B moves the base station 73 to the outside of the rotating body 9. The control command output unit 48B positions the base station 73 above the rotating body 9. That is, in this embodiment, the base station 73 (an antenna of the base station 73) switches between a state in which it is located inside the rotating body 9 and a state in which it is located above the rotating body 9.

[0039] The excavator 2A incorporates a mast 76 that extends upwards from the rotating body 9. The base station 73 (the antenna of the base station 73) is located at an upper end section of the mast 76. The mast 76 extends and retracts in an up-down direction. The mast 76 has a telescopic structure and can extend and retract. The mast 76 extends and retracts in such a way that the base station 73 changes between the state in which it is housed inside the rotating body 9 and the state in which it is positioned above the rotating body 9. As shown in Fig. Figure 7 illustrates that the control command output unit 48B extends the mast 76 to its maximum extent when the base station 73 is used.

[0040] In this embodiment, the central axis of the mast 76 and a rotation axis of the rotating body 9 coincide. The central axis of the mast 76 extends in an up-down direction. The rotating body 9 rotates about the rotation axis. The rotation axis of the rotating body 9 extends in an up-down direction. Because the central axis of the mast 76 and the rotation axis of the rotating body 9 coincide, the excavator 2A can easily perform work in a state where the mast 76 is extended. In this embodiment, the excavator 2A can perform work using the attachment 11 in a state where the base station 73 is usable. Crime prevention system

[0041] Fig. Figure 8 is a diagram illustrating the camera 74 and the light 75 according to the embodiment. As shown in Fig. As illustrated in Figure 8, camera 74 can be attached to mast 76. In the figure shown in Figure 8, the camera 74 can be attached to mast 76. Fig. In the illustrated example 8, camera 74 is attached to mast 76 below base station 73. As shown in Fig. As illustrated in Figure 8, the multitude of cameras 74 can be attached to the mast 76. As shown in Fig. As illustrated in Figure 8, the light 75 can be attached to the camera 74. The light 75 can be attached close to the camera 74. For example, the light 75 can be attached to the mast 76 close to the camera 74.

[0042] Camera 74 and light 75 function as a crime prevention system for work site 3. Camera 74 acts as a crime prevention camera. Light 75 acts as a crime prevention light. Excavator 2A remains at work site 3 during periods when no work is being carried out at work site 3. Examples of periods when no work is being carried out at work site 3 are nights and holidays. During periods when no work is being carried out at work site 3, neither a worker nor an operator of work machine 2 is present at work site 3.

[0043] During periods when no work is being carried out at work site 3, camera 74 records images in the vicinity of excavator 2A. For example, if a suspicious person is in the vicinity of excavator 2A, camera 74 records images while simultaneously tracking the suspect automatically. The image data captured by camera 74 of the area around excavator 2A is transmitted to management server 8. This image data is displayed on a monitor connected to management server 8. The displayed image data is then reviewed, for example, by a security guard. If a suspicious person is in the vicinity of excavator 2A, the security guard can confirm their presence. This helps prevent crimes at work site 3.

[0044] It should be noted that the image data processing unit 48D can identify a suspect using image recognition technology, such as artificial intelligence (AI), from images captured by camera 74. The image data processing unit 48D can only transmit image data to the management server 8 if a suspect is detected. Upon detecting a suspect, the image data processing unit 48D can immediately transmit an alert to the management server 8. It can also send an alert to an administrative authority, such as the police. It should be noted that if the image captured by camera 74 is a moving image (video image), both the still image and the moving image in which a suspect is detected can be transmitted to the management server 8 or the administrative authority.

[0045] During periods when no work is being carried out at work site 3, light 75 illuminates the area around excavator 2A. For example, if a suspicious person is in the vicinity of excavator 2A, light 75 will illuminate the suspect while automatically tracking them. This helps prevent crimes at work site 3. Communication procedures

[0046] Fig. Figure 9 is a diagram describing a communication procedure by the communication system 7 according to the embodiment. The communication system 7 includes a fixed base station 77 and the base station 73 (mobile base station) provided at the first excavator 201.

[0047] The second excavator 202 and the third excavator 203 can be deployed at work site 3, which has poor communication conditions, for example, in a mountainous region. Neither the second excavator 202 nor the third excavator 203 is equipped with base station 73. If the second excavator 202 and the third excavator 203 are operating outside the communication range of the fixed base station 77, neither the second excavator 202 nor the third excavator 203 can transmit operational data to the management server 8. The information terminal 5 cannot transmit a remote control command to either the second excavator 202 or the third excavator 203.

[0048] In this embodiment, the first excavator 201, which includes the base station 73, is located at a place where a communication link can be established between the management server 8 and the second excavator 202 and the third excavator 203. The first excavator 201, which includes the base station 73, is located at a place where a communication link can be established between the information terminal 5 and the second excavator 202 and the third excavator 203. The first excavator 201, which includes the base station 73, can be located at a location where, for example, a communication link can be established between the second excavator 202 and the fixed base station 77. The first excavator 201 can be located at the work site 3 where the second excavator 202 performs work. The first excavator 201 can perform work together with the second excavator 202 at work site 3, where the second excavator 202 is performing work.

[0049] If the first excavator 201, which includes the base station 73, is located in a position where it can communicate with both the second excavator 202 and the management server 8, the operational data processing unit 48C of the second excavator 202 can transmit the operational data of the second excavator 202 to the management server 8 via the base station 73 provided at the first excavator 201. The operating command receiving unit 48A of the second excavator 202 can receive the remote control command from the information terminal 5 via the base station 73 provided at the first excavator 201. The control command output unit 48B of the second excavator 202 can issue a control command to initiate the operation of the second excavator 202 based on the remote control command.

[0050] Similarly, if the first excavator 201, which includes the base station 73, is located in a position where the first excavator 201 can communicate with both the third excavator 203 and the management server 8, the vehicle-mounted control unit 40 of the third excavator 203 can transmit the operating data of the third excavator 203 to the management server 8 via the base station 73. The vehicle-mounted control unit 40 of the third excavator 203 can issue a control command to initiate the operation of the third excavator 203 based on the remote control command received via the base station 73.

[0051] If a worker or operator of excavator 2A (202 and 203) at work location 3 carries a mobile device 78, and the first excavator 201, which includes base station 73, is located where it can communicate with the mobile device 78, the worker or operator can use the mobile device 78. If the first excavator 201, which includes base station 73, is located where it can communicate with both the mobile device 78 and the management server 8, the mobile device 78 can communicate with the management server 8 via base station 73.

[0052] If, for example, the vehicle-mounted control unit 40 of the second excavator 202 cannot communicate with the base station 73, the mobile device 78 can receive the operating data of the second excavator 202 from the vehicle-mounted control unit 40 of the second excavator 202. The mobile device 78 can receive the operating data of the second excavator 202 from the vehicle-mounted control unit 40 of the second excavator 202 via a different communication method than the communication method of the base station 73 of the mobile communication network. For example, the mobile device 78 can receive the operating data of the second excavator 202 from the vehicle-mounted control unit 40 of the second excavator 202 via a wireless local area network (LAN) or a wireless personal area network (PAN). An example of a wireless LAN is WiFi (registered trademark). An example of a wireless PAN is Bluetooth (registered trademark).After receiving the operating data from the second excavator 202, the mobile device 78 can transmit the operating data of the second excavator 202 to the management server 8 via the base station 73. The same applies to the third excavator 203. Effects

[0053] As described above, according to the embodiment, the base station 73 is provided on the excavator 2A, and the excavator 2A functions as a mobile base station, thereby improving the communication environment of the work site 3. As with reference to Fig. As described in section 9, if the first excavator 201 is located at the work location 3 of the second excavator 202 with the base station 73, the vehicle-mounted control unit 40 of the second excavator 202 can transmit the operating data of the second excavator 202 to the management server 8 via the base station 73, even if the work location 3, where the second excavator 202 is working, is outside the communication range of the fixed base station 77.

[0054] In this embodiment, the excavator 2A is equipped with a crime prevention system that includes at least one camera 74 and one light 75. Thus, the crime prevention system monitors the area around the excavator 2A while it remains at work site 3 during periods when no work is being carried out at work site 3, thereby preventing crimes at work site 3. Other embodiments

[0055] In the embodiment described above, data associated with the base station 73, such as the amount of data transmitted by the base station 73, can be stored in the data storage device 50. The data associated with the base station 73 can be transmitted from the vehicle-mounted control unit 40 of the first excavator 201 to the management server 8. The data associated with the base station 73 can also be transmitted from the vehicle-mounted control unit 40 of the first excavator 201 to a communication service provider, for example, an internet service.

[0056] In the embodiment described above, the mast 76 can extend and retract, and when the base station 73 is used, the mast 76 extends so that the antenna of the base station 73 is located above the rotating body 9. The base station 73 can also be used in a state where its antenna is housed inside the rotating body 9.

[0057] In the embodiment described above, the mast 76 may neither extend nor retract. The mast 76 may be in an extended position, so that the antenna of the base station 73 is permanently located above the rotating body 9. The antenna of the base station 73 can be permanently positioned above the rotating body 9 by attaching the non-extending mast 76 to the rotating body 9, positioning the upper end section of the mast 76 above the rotating body 9, and arranging the antenna of the base station 73 at the upper end section of the mast 76. The base station 73 can be continuously operational. A communication device capable of using the base station 73 can be continuously able to communicate via the base station 73.For example, both the second excavator 202 and the third excavator 203 and the mobile terminal 78 described above can be constantly able to communicate with the management server 8 or the information terminal 5 via the base station 73.

[0058] In the embodiment described above, the working machine 2 equipped with the base station 73 can be a bulldozer 2B or a dump truck 2C. Reference symbol list
