The information necessary for the detection that the installation of the luggage has been completed is, for example, information regarding the load acting on the wire rope 311.

(Input Reception Unit)
The input reception unit 323 receives a setting input of one of a plurality of transport modes of the working machine (mobile crane C). The input reception unit 323 sends information related to the received transport mode to the control unit 324 described later.

The input reception unit 323 may be, for example, a switch operated by the worker. However, the input reception unit 323 is not limited to a switch. For example, the input reception unit 323 may be configured with an icon displayed on a display unit such as a touch panel (display unit 318 in this embodiment). The input reception unit 323 may receive, for example, a mode setting input sent from a remote control device for remotely controlling the work machine. However, the configuration of the input reception unit 323 is not limited to that of this embodiment.

The transport modes are explained below. The transport modes correspond to the types of transport performed by the mobile crane C. The transport modes may be considered as modes for specifying the type of destination location information (e.g., location information of a temporary placement position or location information of an attachment position) acquired by the destination location information acquisition method described below. For example, the transport modes include a temporary placement mode and an attachment mode. The transport modes may or may not include modes other than the temporary placement mode and the attachment mode.

The temporary placement mode is a mode that is selected when the mobile crane C transports the load to a temporary placement position. In other words, the temporary placement mode can be considered as a mode for acquiring position information of the temporary placement position using the destination position information acquisition method described below. In the temporary placement mode, the mobile crane C acquires position information of the temporary placement position (e.g., coordinates of the temporary placement position) in order to transport the load. The temporary placement position is a place where the load is temporarily placed before being transported to the attachment position.

The attachment mode is a mode that is selected when the mobile crane C transports a load to an attachment position. In other words, the attachment mode can be considered as a mode for acquiring the position information of the attachment position using the destination position information acquisition method described below. In the attachment mode, the mobile crane C acquires the position information of the attachment position (e.g., the coordinates of the attachment position) in order to transport the load. The attachment position is, for example, the position where the load is assembled in a building.

(Acquisition Department)
The acquisition unit 325 acquires location information of multiple destinations of the package. The acquisition unit 325 acquires the location information of multiple destinations of the package, for example, from an information reading device 7 described below via the first communication unit 320. The location information of the destinations includes, for example, location information of a temporary placement location and location information of an attachment location. The acquisition unit 325 sends the acquired location information of multiple destinations to a control unit 324 described below.

When the location where the luggage is carried in is far from the location where the luggage is attached, multiple temporary storage locations may be required. In this case, the location information of the destination may include location information of multiple temporary storage locations.

(Control Unit)
The control unit 324 controls the operation of each element of the above-described mobile crane C. The control unit 324 may be a circuit or device having a computing capability.

The control unit 324 may include, for example, at least one of a CPU (central processing unit), an MPU (micro processing unit), and a GPU (graphics processing unit). For example, the control unit 324 may be a control unit dedicated to the position information acquisition system of the delivery destination.

The control unit 324 may also be a control device such as a safety device (e.g., an overload prevention device) provided on the mobile crane C. The functions of the control unit 324 described below may be realized by a single control unit, or may be realized by the cooperation of multiple control units.

When the control unit 324 acquires information about the transport mode from the input reception unit 323, it sets the transport mode of the mobile crane C to the acquired transport mode. For example, a mobile crane C that performs temporary placement transport work is set to the temporary placement mode. On the other hand, a mobile crane C that performs installation transport work is set to the installation mode.

The control unit 324 also acquires position information of multiple transport destinations from the acquisition unit 325. From the acquired position information of multiple transport destinations, the control unit 324 acquires position information (first position information) of the transport destination that corresponds to the information on the transport mode acquired from the input acceptance unit 323 (hereinafter referred to as the "set transport mode").

Specifically, when the set transport mode is the temporary placement mode, the control unit 324 acquires the position information of the temporary placement position from the acquired position information of the multiple transport destinations. In this case, the first position information is the position information of the temporary placement position.

In addition, when the set transport mode is the attachment mode, the control unit 324 acquires the position information of the attachment position from the acquired position information of the multiple transport destinations. In this case, the first position information is the position information of the attachment position. Note that the control unit 324 may acquire the position information of the transport destinations corresponding to all transport modes (first position information) in advance. Then, the control unit 324 stores the position information of the transport destinations corresponding to all transport modes (first position information) in the memory unit 326 (see FIG. 3).

The control unit 324 may also acquire information about the parcel from the information reading device 7 along with the location information of the destination. The information about the parcel may include at least one of the following information: identification information about the parcel, location information about the origin of the parcel, and specification information about the parcel. Note that the location information of the destination may also be considered to be included in the information about the parcel.

In addition, after the control unit 324 transports the luggage W to the location indicated by the acquired destination location information, it transmits the destination location information to the server 8, which will be described later.

Specifically, when the set transport mode is the temporary placement mode, the control unit 324 transports the luggage W to the temporary placement position, and then sends position information of the temporary placement position to the server 8. In addition, the control unit 324 may send information about the luggage (specifically, identification information of the luggage) to the server 8 together with the position information of the temporary placement position.

When the set transport mode is the attachment mode, the control unit 324 transports the luggage W to the attachment position and then sends the position information of the attachment position to the server 8. The control unit 324 may also send information about the luggage (specifically, luggage identification information) to the server 8 together with the position information of the attachment position.

The control unit 324 also acquires location information (second location information) of the package's origin that corresponds to the set transport mode. The control unit 324 acquires the location information of the package's origin from, for example, the information reading device 7 described below.

When the control unit 324 obtains the location information of the origin of the package from the information reading device 7, the location information of the origin is, for example, the location of the information reading device 7 detected by the position detection unit 74 of the information reading device 7.

The control unit 324 also acquires location information of the origin of the parcel from, for example, the server 8 described below. In this case, the location information of the origin is the location information of the temporary placement position that the control unit 324 sent to the server 8, and is the location information of the temporary placement position where the transportation has already been completed. In other words, the control unit 324 acquires the location information of the temporary placement position where the transportation has been completed from the server 8 as the location information of the origin for the next transportation.

The control unit 324 also generates a control signal for transporting the luggage W to the destination based on the acquired destination position information (temporary placement position position information or attachment position position information). The control signal is a signal for controlling the actuator 340 that drives the operated function unit 350 (see FIG. 3). The control unit 324 has a function for automatically controlling the operated function unit 350 based on the generated control signal.

The control unit 324 also determines whether or not the transport operation can be performed (hereinafter referred to as "transport operation determination"). Specifically, the control unit 324 determines whether or not the luggage W can be transported to the acquired transport destination (i.e., the temporary placement position or the attachment position). The transport operation determination performed by the control unit 324 is described below.

The control unit 324 acquires performance information corresponding to the acquired crane posture information at the destination. This performance information indicates the maximum load of cargo that the mobile crane C can lift in the posture it will assume at the destination. Such performance information may be calculated by computation or may be stored in advance in the memory unit.

The control unit 324 also acquires the weight information of the cargo from the information reading device 7 described below. Then, based on the acquired performance information and the acquired cargo weight information, the control unit 324 determines whether the mobile crane C can transport the cargo to the destination.

Specifically, if the acquired performance information is greater than the weight of the cargo to be transported, the control unit 324 determines that the mobile crane C can transport the cargo to the destination. On the other hand, if the acquired performance information is less than the weight of the cargo to be transported, the control unit 324 determines that the mobile crane C cannot transport the cargo to the destination. The control unit 324 may display the determination result on the display unit 318.

The control unit 324 acquires information regarding the position of the crane (hereinafter referred to as "crane position information"). The control unit 324 acquires the crane position information (coordinates) based on the position information acquired from the position detection unit 317.

The position information of the crane may be information about the position of the position detection unit 317, or may be information about the position of another part of the crane (e.g., the center of rotation of the rotating body 3).

When the crane position information is information relating to the position of the rotation center of the rotating body 3, the control unit 324 acquires information relating to the position of the boom's rotation center based on the position information acquired from the position detection unit 317, information relating to the crane's attitude acquired from the detection unit 322, and the crane specification data acquired from the memory unit (not shown) (e.g., information relating to the positional relationship between the boom's hoisting start point and the rotation center of the rotating body).

The crane position information may be in local coordinates based on a specified position within the work site, or in global coordinates. When the crane position information is in local coordinates, the control unit 324 converts the position information acquired from the position detection unit 317 into local coordinates as appropriate. The method of acquiring the crane position information is not limited to the present embodiment. The crane position information may be any information that can identify the position of the crane at the work site.

The control unit 324 also acquires information about the position of the hook device 312 (e.g., the coordinates of the hook device 312) based on the detection value of the position detection unit 317. The control unit 324 also acquires position information of the baggage W hung on the hook device 312 based on the detection value of the position detection unit 317.

The control unit 324 acquires information regarding the posture of the crane corresponding to the destination (hereinafter referred to as "crane posture information at the destination"). The control unit 324 calculates the crane posture information at the destination based on the crane position information and the cargo destination position information.

The crane posture information at the destination refers to the posture of the crane when the crane has transported the cargo to the destination. In this way, the control unit 324 has the function of acquiring the crane posture information corresponding to the destination based on the crane position information, crane orientation information, and destination position information of the cargo.

The control unit 324 detects that the ground cutting is complete. The control unit 324 also determines whether the ground cutting is complete.

The control unit 324 determines whether or not the ground cutting is complete based on information (e.g., the load acting on the wire rope 311) acquired from the detection unit 322. Specifically, the control unit 324 determines that the ground cutting is complete when the load acting on the wire rope 311 increases and then becomes constant.

The control unit 324 detects that the installation of the luggage is complete. The control unit 324 also determines whether the installation of the luggage is complete.

The control unit 324 determines whether or not the installation of the cargo is complete based on information (e.g., the load acting on the wire rope 311) obtained from the detection unit 322. Specifically, the control unit 324 determines that the installation of the cargo is complete when the load of the cargo is removed from the load acting on the wire rope 311 while the crane is suspending the cargo.

(Information reading device)
The information reading device 7 is operated, for example, by workers 90, 92 (see FIGS. 1 and 2) who are outside the mobile crane C (for example, at the location from which the cargo is transported). The information reading device 7 obtains information about the cargo by reading information from an information storage unit 5 provided on the cargo.

The information storage unit 5 stores information about the luggage corresponding to the luggage W to which the information storage unit 5 is attached. The information storage unit 5 may be, for example, an IC tag, a barcode, or a QR code (registered trademark). In the present embodiment, in order to store information about the luggage including the position information of the temporary placement position and the position information of the attachment position, it is preferable that the information storage unit 5 be a QR code that can store a relatively large amount of information.

When the information storage unit 5 is an IC tag, the information storage unit 5 may be, for example, a passive IC tag that uses radio waves from the information reading device 320 as its power source and does not have a battery, or an active IC tag that has a battery.

The information reading device 7 acquires its own location information. The information reading device 7 then transmits the acquired location information to the mobile crane C.

Specifically, the information reading device 7 has a reading unit 71, a communication unit 72, a control unit 73, and a position detection unit 74.

(Reading unit)
The reading unit 71 acquires information from the information storage unit 5 provided in the baggage W. The reading unit 71 sends the acquired information to the control unit 73.

The reading unit 71 is, for example, a QR code reader that reads information from a QR code. The reading unit 71 may be any of various reading devices that have the function of reading information from the information storage unit 5, depending on the configuration of the information storage unit 5. If the information storage unit 5 is an IC tag, the reading unit 71 is, for example, an RFID reader. In this case, the information reading device 7 may include a writing unit for writing information to the IC tag.

The reading unit 71 establishes wireless communication with the information storage unit 5 based on the operation of the worker 90, and reads the information stored in the information storage unit 5.

The information read by the reading unit 71 is, for example, information about luggage. The information about luggage includes location information of the luggage's destination. Furthermore, the information about luggage may include, for example, at least one of the following: luggage identification information, location information of the luggage's origin, luggage specification information, and luggage construction information.

As described above, the location information of the destination of the luggage includes the location information of the temporary placement position and the location information of the attachment position. In other words, the information storage unit 5 stores the location information of the temporary placement position and the attachment position of the luggage as the location information of the destination of the luggage. If there are multiple temporary placement positions, the information storage unit 5 may store the location information of multiple temporary placement positions.

The location information of the temporary placement position and the installation position of such luggage is information that is determined in advance by a construction plan that is made using an application such as BIM (Building Information Modeling) (hereinafter referred to as a "construction plan application").

The location information of the destination of the package is, for example, the coordinates of the destination of the package (hereinafter simply referred to as "destination coordinates"). The destination coordinates may be local coordinates based on a specified position within the work site, or may be global coordinates.

The luggage specification information may include at least one of the following information: information regarding the luggage dimensions (hereinafter referred to as "luggage dimension information"), information regarding the luggage weight (hereinafter referred to as "luggage weight information"), and information regarding the luggage shape (hereinafter referred to as "luggage shape information").

The construction information for the cargo may include information regarding the construction direction of the cargo and/or the construction sequence of the cargo.

(Position detection unit)
The position detection unit 74 is a GNSS antenna for receiving information from a satellite positioning system such as a Global Positioning System (GPS), etc. The position detection unit 74 obtains information (coordinates) relating to its own position from the satellite positioning system.

In this embodiment, the position detection unit 74 is incorporated in the information reading device 7. Therefore, in this embodiment, the information regarding the position acquired by the position detection unit 74 is also information regarding the position of the position detection unit 74.

In this embodiment, the position detection unit 74 acquires information about its own position in response to the operation of the reading unit 71. Specifically, the position detection unit 74 acquires information about its own position at the time when the reading unit 71 reads information from the information storage unit 5.

When the worker 90 reads information from the information storage unit 5 using the information reading device 7, the worker brings the information reading device 7 close to the information storage unit 5. Therefore, the information relating to the position of the position detection unit 74 at the time when the reading unit 71 reads information from the information storage unit 5 is also the position information of the information storage unit 5 (i.e., the luggage). The position detection unit 74 sends the acquired information relating to the position to the control unit 73. Note that the position detection unit 74 may be omitted.

(Communications Department)
The communication unit 72 establishes communication with the first communication unit 320 of the mobile crane C and sends the acquired information to the first communication unit 320.

The communication unit 72 and the first communication unit 320 are connected for communication via a network such as the Internet. The method of connection between the communication unit 72 and the first communication unit 320 is not particularly limited. The method of connection between the communication unit 72 and the first communication unit 320 may be, for example, a wireless LAN such as WiFi (registered trademark), or Bluetooth (registered trademark), etc.

(Control Unit)
The control unit 73 sends the information obtained from the reading unit 71 to the mobile crane C via the communication unit 72. Specifically, the control unit 73 sends the information related to the cargo obtained from the reading unit 71 (location information of the transport destination) to the mobile crane C via the communication unit 72. In this embodiment, the control unit 73 sends all of the location information of the transport destination obtained from the reading unit 71 to the mobile crane C.

The control unit 73 sends information about the location of the luggage obtained from the position detection unit 74 (i.e., location information about the luggage's origin) to the mobile crane C.

(server)
The server 8 corresponds to an example of a terminal, and is communicatively connected to the mobile crane C via a network such as the Internet. The server and the crane may be connected by wire or wirelessly. From the viewpoint of simplifying the system configuration, the server may be provided, for example, within the body of the crane.

The server 8 receives information from the mobile crane C. The server 8 then stores the acquired information. In addition, the server 8 sends the stored information to the mobile crane C in response to a request from the mobile crane C. The specific configuration of the server 8 is described below.

The server 8 includes a server-side communication unit 81, a control unit 82, and a memory unit 83.

(Server side communication unit)
The server-side communication unit 81 establishes communication with the second communication unit 321 of the mobile crane C to receive information from the mobile crane C. The server-side communication unit 81 may also send information to the mobile crane C.

The server-side communication unit 81 and the second communication unit 321 of the mobile crane C are connected for communication via a network. The server-side communication unit 81 and the second communication unit 321 may also be connected via a local area network.

(Control Unit)
The control unit 82 acquires the first position information from the second communication unit 321 of the mobile crane C via the server-side communication unit 81.

As described above, when the set transport mode is the temporary storage mode, the mobile crane C (specifically, the control unit 324 of the mobile crane C) transports the luggage W to the temporary storage position and then sends position information of the temporary storage position to the server 8. This position information of the temporary storage position corresponds to an example of the first position information acquired by the control unit 82.

In addition, when the set transport mode is the attachment mode, the mobile crane C (specifically, the control unit 324 of the mobile crane C) transports the cargo W to the attachment position and then sends position information of the attachment position to the server 8. This position information of the attachment position corresponds to an example of the first position information acquired by the control unit 82.

The control unit 82 may obtain information about the luggage (specifically, luggage identification information) from the mobile crane C, along with location information about the temporary placement position or the installation position.

The control unit 82 stores the position information of the temporary placement position and the position information of the attachment position acquired from the mobile crane C in the memory unit 83. In addition, when the control unit 82 acquires information about the luggage from the mobile crane C, the control unit 82 stores the position information of the temporary placement position and the position information of the attachment position acquired from the mobile crane C in the memory unit 83 in association with the information about the luggage.

In response to a request from the mobile crane C, the control unit 82 sends the position information of the temporary placement position stored in the memory unit 83 to the mobile crane C as the position information of the baggage's origin. This request may include information about the baggage (specifically, baggage identification information).

The control unit 82 sends the position information of the temporary storage position corresponding to the information about the luggage (specifically, the luggage identification information) to the mobile crane C as the position information of the luggage's origin. In other words, the mobile crane C obtains the position information of the temporary storage position where the transportation has already been completed from the server 8 as the position information of the origin for the next transportation (e.g., installation transportation work).

(Memory unit)
The storage unit 83 stores information. Specifically, the storage unit 83 stores position information of the temporary placement position and position information of the attachment position acquired from the control unit 82. The storage unit 83 may store the position information of the temporary placement position and the position information of the attachment position in association with information related to the luggage (specifically, identification information of the luggage). The storage unit 83 may store the position information of the attachment position as a log related to installation.

<Destination location information acquisition process>
1 to 7, the transport operation of the mobile crane C will be described below. Fig. 4 is a flowchart of a destination position information acquisition process (destination position information acquisition method) in a temporary placement transport operation performed by the mobile crane C.

Figures 4 to 6 are also flowcharts of the temporary placement and transportation work carried out at the work site. The flowcharts shown in Figures 4 to 6 show the work carried out by the worker and the processing carried out by the mobile crane C when the mobile crane C transports the cargo W from the source to the destination.

Figure 7 is a flowchart of the destination location information acquisition process (destination location information acquisition method) during installation and transportation work performed by mobile crane C.

The order of the processes in the flowcharts shown in Figures 4 to 7 may be changed as appropriate to the extent that there is no technical contradiction. Furthermore, the processes in the flowcharts shown in Figures 4 to 7 may be omitted as appropriate.

(Operation example 1)
First, the process of acquiring destination position information when the mobile crane C transports the cargo W from the origin position T0 to the destination position T1 shown in Fig. 1 will be described. The task of transporting the cargo W from the position T0 to the position T1 corresponds to a temporary placement task (first transport task). The position T0 is also the loading position of the cargo W.

Figure 1 shows a mobile crane C placed at a work site. A truck 91 is also shown around the mobile crane C. A load W that has been brought to the work site by the truck 91 is placed on the truck's loading platform. Also, around the load W is a worker 90 holding an information reading device 7.

Also, around the mobile crane C, there is a position T1, which is the destination of the transport. Position T1 is an example of a temporary storage position where the cargo W is temporarily placed.

First, in step S101 of FIG. 4, the operator of the mobile crane C inputs the transport mode setting via the input reception unit 323. In this example, the operator inputs the temporary placement mode via the input reception unit 323.

The transport mode setting does not need to be changed if the transport work does not change. In other words, if temporary placement transport work is to be performed repeatedly, the worker can set the transport mode to the temporary placement mode before the first temporary placement transport work. The worker can input the transport mode setting to the input reception unit 323 by operating a remote control terminal that is communicatively connected to the mobile crane C.

In step S102 of FIG. 4, the input reception unit 323 receives a transport mode setting input from the operator. The input reception unit 323 then sends information about the received transport mode to the control unit 324.

In step S103 of FIG. 4, the control unit 324 sets the acquired transport mode as the transport mode of the mobile crane C. In this example, the control unit 324 sets the temporary placement mode as the transport mode of the mobile crane C.

In step S104 of FIG. 4, a worker 90 standing near the luggage W placed at the position T0 from which the luggage W is transported operates the information reading device 7 to obtain information about the luggage from the information storage unit 5 provided on the luggage W.

The information about the parcel acquired by the information reading device 7 in step S104 includes location information about the destination of the parcel W. In addition, the information about the parcel acquired by the information reading device 7 in step S104 may include identification information about the parcel and/or specification information about the parcel.

The location information of the destination of the luggage includes the location information of the temporary placement location and the location information of the attachment location. In this example, the location information of the temporary placement location is the coordinates of the destination location T1. Furthermore, the coordinates of location T1 are global coordinates. However, the coordinates of location T1 may also be local coordinates based on a specified location within the work site.

The position information of the mounting position is the coordinates of position T2 (see FIG. 2). In this example, the coordinates of position T2 are global coordinates. However, the coordinates of position T2 may also be local coordinates based on a specified position within the work site.

In step S105, the information reading device 7 (specifically, the position detection unit 74) acquires information (coordinates) regarding its own position.

The position detection unit 74 obtains information about its own position when the reading unit 71 reads information from the information storage unit 5.

When the worker 90 reads information from the information storage unit 5 using the information reading device 7, the worker brings the information reading device 7 close to the information storage unit 5. Therefore, the information regarding the position of the position detection unit 74 at the time when the reading unit 71 reads information from the information storage unit 5 is also the position information of the information storage unit 5 (i.e., the luggage W). In other words, the position information acquired by the position detection unit 74 in step S105 is the position information of the origin of the luggage W (i.e., the position information of position T0).

The mobile crane C may also obtain the origin location information by another means. For example, in a construction plan performed using a construction planning application, if the origin location information (in this example, the location where the cargo W is brought in) is predetermined, the mobile crane C may obtain the origin location information from the construction planning application or a server. In this case, step S105 may be omitted.

In step S106, the information reading device 7 sends the acquired information about the cargo to the mobile crane C. The information reading device 7 may also send the location information of the transport source together with the information about the cargo to the mobile crane C.

In this example, the information about the luggage that the information reading device 7 sends to the mobile crane C in step S106 includes the coordinates of the destination position T1 (see FIG. 1) and the coordinates of the destination position T2 (see FIG. 2). In addition, the information about the luggage that the information reading device 7 sends to the mobile crane C in step S106 includes identification information about the luggage W and/or specification information about the luggage.

In addition, in step S106, the information reading device 7 may automatically send information about the cargo to the mobile crane C when the processing of step S104 (or step S105 if step S105 is performed) is completed.

Alternatively, in step S106, the information reading device 7 may, in response to a request from the mobile crane C, send information about the cargo to the mobile crane C after the processing of step S104 (or step S105, if step S105 is performed) is completed.

The following process is performed by the mobile crane C (specifically, the control unit 324). In step S107, the control unit 324 of the mobile crane C acquires information about the cargo from the information reading device 7 via the first communication unit 320 and the acquisition unit 325.

Next, in step S108, the control unit 324 acquires destination location information corresponding to the set transport mode (in this example, temporary placement mode) from information regarding the locations of multiple transport destinations included in the acquired information about the luggage (specifically, location information of the temporary placement location and location information of the attachment location). In this example, in step S108, the control unit 324 acquires location information (e.g., coordinates) of position T1, which is the destination (temporary placement location).

In step S108, the control unit 324 may acquire position information (first position information) of the transport destinations corresponding to all transport modes. In this case, the control unit 324 may store the position information (first position information) of the transport destinations corresponding to all transport modes in the memory unit 326 (see FIG. 3).

The above steps S101 to S108 are the process of acquiring destination location information during temporary placement and transportation work. Below, we will explain the operation of mobile crane C after acquiring destination location information.

First, referring to Figure 5, we will explain the process when the mobile crane C operates based on the operator's operation.

In step S201 of FIG. 5, the control unit 324 of the mobile crane C displays the acquired source position information (in this example, the coordinates of position T0) and destination position information (in this example, the coordinates of position T1) on the display unit 318.

For example, the control unit 324 displays the source position information (position T0 in this example) and the destination position information (position T1 in this example) on the display unit 318. It is preferable that the source position information and the destination position information are displayed in a manner that allows the worker to intuitively recognize the source position and the destination position.

In addition, in step S201, the control unit 324 may display information on the operation for moving the hook device 312 to position T0 (hereinafter referred to as "crane operation information") on the display unit 318 based on the acquired position information of the transport source (in this example, the coordinates of position T0).

The crane operation information may be, for example, the operation direction and operation amount of the operation input unit 319. In addition, the crane operation information may include, for example, information regarding the posture that the crane can take when moving the hook device 312 to position T0 (hereinafter referred to as "crane posture information").

In addition, in step S108, when the control unit 324 has acquired the destination position information (first position information) corresponding to all transport modes, the control unit 324 may acquire the destination position information corresponding to the set transport mode (in this example, the temporary placement mode) from the memory unit 326. Thereafter, the control unit 324 displays the origin position information (in this example, the coordinates of position T0) together with the acquired destination position information (in this example, the coordinates of position T1) on the display unit 318.

In step S202, the operator of the mobile crane C operates the operation input unit 319 to move the hook device 312 to position T0.

In step S203, the worker 90 (slinger) hooks the sling wire rope 316 onto the cargo W at the appropriate time.

In step S204, the worker operates the operation input unit 319 to transport the luggage W to position T1. Then, the worker 92 in the vicinity of position T1 detaches the luggage from the hook device 312.

In step S205, the control unit 324 determines whether or not the transport of the luggage W has been completed. The state in which the transport of the luggage W has been completed may be considered as a state in which the luggage W has been transported to the destination (position T1 in this example) and the luggage W has been detached from the hook device 312.

The control unit 324 calculates the position of the luggage W hung on the hook device 312, and when the calculated position of the luggage W matches the position indicated by the destination position information (position T1 in this example), it determines that the luggage W has been transported to the destination.

The control unit 324 also determines that the luggage W has been placed at a specified position at the destination based on information obtained from the detection unit 322 (e.g., the load acting on the wire rope 311).

If it is determined that the transportation of the luggage W is complete (in this example, the temporary placement of the luggage W is complete) ("YES" in step S205), the control unit 324 transitions the control process to step S206.

If it is determined that the transportation of the luggage W has not been completed ("NO" in step S205), the control unit 324 repeats the control process of step S205.

In step S206, the control unit 324 sends the location information of the destination of the package (in this example, the coordinates of position T1) along with the identification information of the package to the server 8. The control unit 324 may also send the time when the package is completed along with the location information of the destination of the package (in this example, the coordinates of position T1) to the server 8. The server 8 stores the acquired information as a log in the memory unit 83.

The above is an explanation of the processing when the mobile crane C operates based on the operation of the worker. Next, referring to FIG. 6, the processing when the mobile crane C transports cargo W by automatic control will be explained. Note that even when the mobile crane C operates by automatic control, there may be cases where an operator is on board the operator's cab 313 of the mobile crane C.

First, in step S301 of FIG. 6, the control unit 324 generates a control signal (also referred to as a first control signal) for moving the hook device 312 from the origin position T0 to the destination position T1 based on the acquired origin position information (in this example, the coordinates of position T0) and destination position information of the luggage W (in this example, the coordinates of position T1).

In addition, in step S301, the control unit 324 of the mobile crane C generates a control signal (also called a second control signal) for moving the hook device 312 from its current position to position T0 based on the position information of the current position of the hook device 312 and the acquired position information of the transport source (in this example, the coordinates of position T0).

The control signal is a control signal (also referred to as a first control signal) for automatically controlling the actuator 340 that drives the operated functional unit 350 of the mobile crane C. For example, the control signal includes a control signal for rotating the boom, a control signal for raising and lowering the boom, a control signal for extending and retracting the boom, and/or a control signal for raising and lowering the hook device 312.

In step S302, the control unit 324 moves the hook device 312 to the origin position T0 (baggage loading position) based on the second control signal. Note that in the case of a second or subsequent temporary placement and transport operation, the origin position (hereinafter referred to as the "origin position for the second or subsequent transport") may differ from position T0. In that case, the second control signal is a control signal for moving the hook device 312 from the current position to the origin position for the second or subsequent transport.

In step S303, the worker 90 (slinger) hooks the sling wire rope 316 onto the cargo W at the appropriate time.

In step S304, the control unit 324 transports the luggage W from position T0 to position T1 based on the generated first control signal. After that, the worker 92 in the vicinity of position T1 detaches the luggage from the hook device 312.

In step S305, the control unit 324 determines whether the transport of the luggage W has been completed. The method for determining whether the transport of the luggage W has been completed is as described above.

If it is determined that the transportation of the luggage W is complete (in this example, the temporary placement of the luggage W is complete) ("YES" in step S305), the control unit 324 transitions the control process to step S306.

If it is determined that the transportation of the luggage W has not been completed ("NO" in step S305), the control unit 324 repeats the control process of step S305.

In step S306, the control unit 324 sends the location information of the destination of the package (in this example, the coordinates of position T1) along with the identification information of the package to the server 8. The control unit 324 may also send the time when the package is completed along with the location information of the destination of the package (in this example, the coordinates of position T1) to the server 8. The server 8 stores the acquired information in the memory unit 83 as a log related to installation. Such a log related to installation can be used for performance management.

After that, if the temporary placement and transport operation is to be repeated, the process returns to step S301 and repeats the control processing of steps S301 to S306.

The above is an explanation of the process when the mobile crane C transports cargo W under automatic control.

(Operation example 2)
Next, the process of acquiring destination position information when the mobile crane C transports the cargo W from the origin position T1 to the destination position T2 shown in Fig. 2 will be described. The task of transporting the cargo W from the position T1 to the position T2 corresponds to the installation transport task (second transport task). The position T1 is also the temporary placement position in the above-mentioned operation example 1.

Figure 2 shows a mobile crane C placed at a work site. The mobile crane C shown in Figure 2 may be the same model as the mobile crane C shown in Figure 1, or it may be a different model. Also, the mobile crane C shown in Figure 2 may be the same crane as the mobile crane C shown in Figure 1.

In addition, around the mobile crane C, there is a position T1, which is the source of transport, and a position T2, which is the destination of transport. Position T1 is the position where the cargo W is temporarily placed during the temporary storage operation.

In addition, around position T1, there is a worker 92 holding an information reading device 7. Although not shown in the figure, there are also workers around position T2, which is the destination.

First, in step S401 of FIG. 7, the operator of the mobile crane C inputs the transport mode setting via the input reception unit 323. In this example, the operator inputs the installation mode via the input reception unit 323.

The transport mode setting does not need to be changed if the transport work does not change. In other words, if the installation transport work is to be performed repeatedly, the worker only needs to set the transport mode to the installation mode before the first installation transport work.

In step S402 in FIG. 7, the input reception unit 323 receives a transport mode setting input from the operator. The input reception unit 323 then sends information about the received transport mode to the control unit 324.

In step S403 of FIG. 7, the control unit 324 sets the acquired transport mode as the transport mode of the mobile crane C. In this example, the control unit 324 sets the attachment mode as the transport mode of the mobile crane C.

In step S404 of FIG. 7, a worker 92 standing near the luggage W placed at the position T1 from which the luggage W is transported operates the information reading device 7 to obtain information about the luggage from the information storage unit 5 provided on the luggage W.

The information about the parcel acquired by the information reading device 7 in step S404 includes at least location information about the destination of the parcel W. In addition, the information about the parcel acquired by the information reading device 7 in step S404 may include identification information and/or specification information about the parcel.

The location information of the destination of the package includes the location information of the temporary placement location and the location information of the attachment location. In this example, the location information of the temporary placement location is the coordinates of location T1. Furthermore, the location information of the attachment location is the coordinates of location T2 (see FIG. 2).

Note that in the installation transport work of this example, position T1 is the origin of transport, but in the temporary placement transport work of operation example 1, it is the destination. In other words, the position information of the destination of the luggage means the position information of the position that will be the destination in the temporary placement transport work or the installation transport work.

In addition, in step S404, the information reading device 7 (specifically, the position detection unit 74) may acquire information (coordinates) regarding its own position.

When the worker 92 reads information from the information storage unit 5 using the information reading device 7, the worker 92 brings the information reading device 7 close to the information storage unit 5. Therefore, the information regarding the position of the position detection unit 74 at the time when the reading unit 71 reads information from the information storage unit 5 is also the position information of the information storage unit 5 (i.e., the luggage W). This position information of the luggage W is also the position information of the transport source of the luggage W.

In step S405, the information reading device 7 sends the acquired information about the luggage to the mobile crane C. If the information reading device 7 has acquired the luggage position information in step S404, the information about the luggage may be sent to the mobile crane C along with the luggage position information (in this example, the coordinates of the position T1 from which the luggage is to be transported).

In this example, the information about the luggage that the information reading device 7 sends to the mobile crane C in step S405 includes the coordinates of the temporary placement position T1 (see FIG. 1) and the coordinates of the attachment position T2 (see FIG. 2), which are the position information of the destination. In addition, the information about the luggage that the information reading device 7 sends to the mobile crane C in step S405 includes the identification information of the luggage W and the specifications information of the luggage.

The following process is performed by the mobile crane C (specifically, the control unit 324). In step S406, the control unit 324 of the mobile crane C acquires information about the cargo from the information reading device 7 via the first communication unit 320.

Next, in step S407, the control unit 324 acquires the location information of the destination (i.e., the location information of the attachment position) corresponding to the set transport mode (in this example, the attachment mode) from the information on the locations of the multiple transport destinations included in the acquired information on the luggage (specifically, the location information of the temporary placement location and the location information of the attachment location). In this example, in step S407, the control unit 324 acquires the location information (e.g., coordinates) of position T2, which is the transport destination (attachment location).

In step S408, the control unit 324 acquires the origin position information from the server 8. In this example, the origin position information is the position information (e.g., coordinates) of the temporary placement position, position T1.

As described above, when the set transport mode is the temporary placement mode, the mobile crane C (specifically, the control unit 324 of the mobile crane C) transports the luggage W to the temporary placement position, and then sends position information of the temporary placement position to the server 8. This position information of the temporary placement position becomes the position information of the transport source in the installation transport work.

The mobile crane C (specifically, the control unit 324) sends a request to the server 8 to obtain the location information of the origin. This request includes the identification information of the cargo. The server 8 obtains the location information of the origin from the memory unit 83, which corresponds to the identification information of the cargo included in the request received from the mobile crane C. The server 8 then sends the location information of the origin to the mobile crane C.

The processing of step S408 is not limited to the above timing and may be performed at any appropriate timing. Also, in step S404, if the information reading device 7 (specifically, the position detection unit 74) has acquired information regarding its own position (i.e., the position information of the origin of the luggage W), the control unit 324 may acquire the position information of the origin from the information reading device 7. In this case, the processing of step S408 may be omitted.

The above steps S401 to S408 are the process of acquiring destination location information during the installation and transportation work. The operation of the mobile crane C after acquiring destination location information is the same as the process shown in Figures 4 and 5.

<Actions and Effects of the Present Embodiment>
In the present embodiment having the above configuration, the mobile crane C acquires information about the cargo from the information reading device 7. The mobile crane C then acquires destination position information (i.e., position information of the temporary placement position) corresponding to the set transport mode (e.g., temporary placement mode) from the multiple destination position information contained in the acquired cargo information. In this way, the mobile crane C according to this embodiment can efficiently acquire destination position information of the cargo.

[Embodiment 2]
Next, a second embodiment of the present invention will be described with reference to Fig. 8. The mobile crane C2 according to this embodiment does not include the input receiving unit 323 that is included in the mobile crane C according to the first embodiment. The rest of the configuration of the mobile crane C2 is the same as that of the mobile crane C according to the first embodiment.

On the other hand, the information reading device 7B according to this embodiment includes an input receiving unit 75 in addition to the components of the information reading device 7 according to the above-described first embodiment. The rest of the configuration of the information reading device 7B is the same as the configuration of the information reading device 7 according to the first embodiment.

In this embodiment, first, the worker inputs the transport mode setting via the input reception unit 75 of the information reading device 7B. If the work performed by the mobile crane C corresponding to the information reading device 7B is a temporary placement transport work, the worker inputs the temporary placement mode via the input reception unit 75. Also, if the work performed by the mobile crane C corresponding to the information reading device 7B is an installation transport work, the worker inputs the installation mode via the input reception unit 75.

The input reception unit 75 then receives the transport mode setting input from the worker. The input reception unit 75 then sends information about the received transport mode to the control unit 73. The control unit 73 sets the acquired transport mode in the information reading device 7 as the transport mode of the mobile crane C.

Next, similar to step S104 in FIG. 4 and step S404 in FIG. 7, a worker near the luggage W placed at the origin position T0 (in the case of FIG. 4) or position T1 (in the case of FIG. 7) operates the information reading device 7B to obtain information about the luggage from the information storage unit 5 provided on the luggage W.

Next, the control unit 73 acquires the location information of the destination corresponding to the set transport mode (temporary placement mode or attachment mode) from the information on the locations of the multiple transport destinations included in the acquired information on the luggage (specifically, the location information of the temporary placement position and the location information of the attachment position).

Then, the information reading device 7B sends the destination location information corresponding to the set transport mode to the mobile crane C. Other operations of the information reading device 7B are the same as those of the information reading device 7 in the above-described embodiment 1.
