  The cargo handling information storage device 31 stores information related to a plurality of cargo handling works assigned to the operator W or the cargo handling vehicle 1. Specifically, for example, the cargo handling information storage device 31 stores, as the information related to the cargo handling work, information relating to the unloading position and the loading position, information relating to the traveling route at the time of transporting the cargo, and the like for each cargo handling work. Is stored in association with.

  The proficiency evaluation device 32 evaluates the proficiency of the operator W regarding the operation of the cargo handling vehicle 1 based on the measurement result of the biological information of the operator W, that is, the biological information of the operator W measured by the biological information measuring device 2. . A specific method of evaluating the proficiency by the proficiency evaluation device 32 will be described later with reference to FIG.

  The operator information storage device 33 stores, for each operator W, information relating to the operator W who operates (drives) the cargo handling vehicle 1. Specifically, the operator information storage device 33 stores, for example, information on the cargo handling work performed by the operator W in the past, information on the required work time required for the cargo handling work, and information on the operator W during the cargo handling work. Information about the proficiency evaluated based on the biological information is stored. That is, the operator information storage device 33 stores information indirectly representing the biological information of the operator W measured by the biological information measuring device 2 (information related to the proficiency evaluation result by the proficiency evaluation device 32).

  The cargo handling work assignment device 34 uses the cargo handling vehicle 1 for the operator W that operates the cargo handling vehicle 1 in the manned operation mode and the cargo handling vehicle 1 in the unmanned operation mode from a plurality of predetermined cargo handling operations. One or more cargo handling operations to be performed. Then, the cargo handling work allocating device 34 relates to the cargo handling vehicle 1 in the manned operation mode operated by the operator W to which the cargo handling work is assigned and the cargo handling vehicle 1 in the unmanned operation mode to which the cargo handling work is assigned. Submit information. Further, the cargo handling work assigning device 34 provides the operator W who has been evaluated the skill based on the evaluation result of the skill related to the operation of the cargo handling vehicle 1, that is, the skill evaluated by the skill evaluating device 32. On the other hand, the cargo handling work requiring the maneuvering whose proficiency is evaluated to be lower than the predetermined standard is preferentially assigned. Hereinafter, the detailed operation of the cargo handling work assignment device 34 will be described with reference to FIG.

With reference to FIG. 2, a flow when the cargo handling work assignment device 34 assigns cargo handling work will be described.
First, the cargo handling work allocating device 34 determines the operator based on the information related to the cargo handling work acquired from the cargo handling information storage device 31 and the information related to the cargo handling work previously performed by the operator W acquired from the operator information storage device 33. W predicts the work required time required for each of the plurality of cargo handling works (step S1).

  Then, the cargo handling work assignment device 34 provides one or more operators to the operator W such that the time during which the operator W operates the cargo handling vehicle 1 (operating time) exceeds a predetermined time (for example, 2 hours) when performing the cargo handling work. Is assigned (step S2). That is, the cargo handling work allocating device 34 performs the cargo handling work on the operator W based on the work required time predicted in step S1 so that the operator W operates the cargo handling vehicle 1 for at least the predetermined time to perform the cargo handling work. assign. The cargo handling work assigning device 34 that has assigned the cargo handling work to the operator W transmits the information related to the assigned cargo handling work to the cargo handling vehicle 1 operated by the operator W. Further, the cargo handling work allocating device 34 allocates the remaining cargo handling work not allocated to the operator W to the cargo handling vehicle 1 in the unmanned operation mode, and transmits information related to the cargo handling work allocated to the cargo handling vehicle 1. . Thus, the operator W that operates the cargo handling vehicle 1 in the manned operation mode and the cargo handling vehicle 1 in the unmanned operation mode start the cargo handling work assigned by the cargo handling work assignment device 34, and the biological information measuring device 2 uses the cargo handling vehicle 1 The biological information (the pulse rate or the heart rate) of the operator W who is driving is measured.

  Then, the cargo handling work allocating device 34 determines whether the cargo handling work assigned to the operator W in step S2 is completed based on the information on the progress of the cargo handling work received from the cargo handling vehicle 1 (step S2). S3). When it is determined in step S3 that the operator W has not completed the cargo handling work, the cargo handling work assignment device 34 repeats the above step S3. That is, until the cargo handling work assigned to the operator W is completed, the cargo handling work assignment device 34 does not perform the following steps S4 and subsequent steps.

  If it is determined in step S3 that the operator W has completed the cargo handling operation, the proficiency evaluation device 32 controls the operator W to operate the cargo handling vehicle 1 based on the biological information measured by the biological information measuring device 2 during the cargo handling operation. Is evaluated (step S4). The result of the evaluation of the proficiency level in step S4 is stored in the operator information storage device 33 for each cargo handling operation requiring the operation of the evaluation target. The evaluation method in step S4 will be described later with reference to FIG.

  Next, the cargo handling work allocating device 34 determines whether the proficiency of the operator W in controlling the cargo handling vehicle 1 has been evaluated to be lower than a predetermined standard based on the proficiency evaluation result stored in the operator information storage device 33. A decision is made (step S5).

  The cargo handling work assignment device 34 determines in step S5 that the proficiency related to the operation of the cargo handling vehicle 1 is not evaluated below the predetermined reference, that is, the proficiency related to the manipulation required for the cargo handling performed by the operator W. If it is determined in step S4 that the degree has reached the predetermined criterion, it is determined that there is no need to improve the operation skills of the operator W, and no additional cargo handling work is assigned to the operator W. The operator W that has completed the cargo handling operation gets off the cargo handling vehicle 1 and switches to the unmanned operation mode.

  On the other hand, the cargo handling work allocating device 34 determines in step S5 that the proficiency related to the manipulation of the cargo handling vehicle 1 has been evaluated to be lower than the predetermined criterion, that is, the handling related to the manipulation required for the cargo handling performed by the operator W. If the proficiency is evaluated to be lower than the predetermined standard, it is determined that the operating skill of the operator W needs to be improved, and one or more additional cargo handling work is assigned to the operator W (step S6). Specifically, the cargo handling work assignment device 34 is configured to store a plurality of cargo handling work information based on the information related to the plurality of cargo handling work stored in the cargo handling work information storage device 31 and the information related to the skill level stored in the operator information storage device 33. A cargo handling work to be additionally assigned to the operator W is selected from the cargo handling work. At this time, the cargo handling work allocating device 34 selects, as the additional cargo handling work, a cargo handling work requiring a maneuver whose proficiency is evaluated to be lower than a predetermined standard. The cargo handling work allocating device 34 that has assigned the additional cargo handling work to the operator W transmits information related to the additional cargo handling work to the cargo handling vehicle 1 operated by the operator W. In this way, the operator W whose proficiency for the predetermined operation is evaluated to be lower than the predetermined criterion, after completing the assigned additional cargo handling work, gets off the cargo handling vehicle 1 and switches to the unmanned operation mode.

  With reference to FIG. 3, a description will be given of a method of evaluating the proficiency of the operator W regarding the operation of the cargo handling vehicle 1. FIG. 3A shows an example of a change in the pulse rate of the operator W whose proficiency is evaluated to be high, and FIG. 3B shows an example of a change of the pulse rate of the operator W whose proficiency is evaluated to be low. Represents.

  As shown in FIG. 3 (A), the operator W having a high level of proficiency in the operation of the cargo handling vehicle 1 does not become nervous during the operation of the cargo handling vehicle 1 when picking up or placing luggage, for example. No significant fluctuation occurs in the pulse of W. Accordingly, if the measured pulse rate or heart rate of the operator W per predetermined time is close to the pulse rate or heart rate of the operator W in a normal state (for example, 80), the proficiency evaluation device 32 determines that the operator W has a cargo handling vehicle. It is evaluated that the proficiency related to the first operation has reached a predetermined standard. Specifically, for example, if the measured pulse rate or heart rate is maintained at less than 100, the proficiency evaluation device 32 determines that the measured pulse rate or heart rate change (the difference between the minimum value and the maximum value) is 20%. If the measured value is less than 125%, or if the measured rate of change in pulse rate or heart rate (percentage of the maximum value with the minimum value being 100%) is less than 125%, the proficiency level has reached a predetermined standard. Evaluate.

  On the other hand, as shown in FIG. 3B, the operator W having a low level of proficiency in maneuvering the cargo handling vehicle 1 may be nervous when manipulating the cargo handling vehicle 1, for example, when picking up luggage or placing luggage. , A large fluctuation occurs in the pulse of the operator W. Therefore, the proficiency evaluation device 32 determines that the measured pulse rate or heart rate per predetermined time of the operator W is greater than the pulse rate or heart rate (for example, 80) of the operator W in a normal state. When the number approaches (for example, 100), it is evaluated that the proficiency of the operator W regarding the operation of the cargo handling vehicle 1 is lower than a predetermined standard. Specifically, the proficiency evaluation device 32, for example, when the measured pulse rate or the heart rate reaches 100, when the measured change in the pulse rate or the heart rate is 20 or more, or When the rate of change of the pulse rate or the heart rate is 125% or more, it is evaluated that the proficiency is lower than a predetermined standard.

  With reference to FIG. 4, an embodiment relating to the assignment of the cargo handling work based on the evaluation result of the proficiency in steps S5 and S6 will be described. In the cargo handling work allocating system S according to the present embodiment, the cargo handling work allocating device 34 allocates the cargo handling work A to I to the three operators WA to WC in step S2, and assigns the remaining cargo handling work J to M. Assigned in step S6.

  In the present embodiment, in step S2, the cargo handling operations A to C are assigned to the operator WA, the cargo handling operations D to F are assigned to the operator WB, and the cargo handling operations G to I are assigned to the operator WC. It is assumed that information relating to the cargo handling work shown in FIG. As shown in FIG. 4A, the information on the cargo handling work includes information on the height of the unloading position and the loading position as information on the work content of the cargo handling work. In the columns of the unloading position and the unloading position in FIG. 4A, “high” indicates a high place, and “low” indicates a low place. Therefore, for example, the cargo handling operation A requires maneuvering of the cargo handling vehicle 1 to pick up luggage in a high place during unloading (loading), and the luggage to a high place when unloading (unloading). It is necessary to steer the cargo handling vehicle 1 for placing the cargo, and the cargo handling work C requires the handling of the cargo handling vehicle 1 for picking up the cargo in the low place when unloading, and the cargo handling for placing the cargo in the low place when unloading. The operation of the vehicle 1 is required.

  Further, in the present embodiment, in step S4, the proficiency level relating to the operation of the cargo handling vehicle 1 for each of the cargo handling operations A to I is determined based on the biological information of the operators WA to WC when performing the cargo handling operations A to I. The operator information storage device 33 that has been evaluated stores information on the operator WA shown in FIG. 4B, information on the operator WB shown in FIG. 4C, and information on the operator WC shown in FIG. It is assumed that information is stored. In the proficiency columns in FIGS. 4B to 4D, “」 ”indicates that the proficiency has reached the predetermined standard, and“ × ”indicates that the proficiency is lower than the predetermined standard. It shows that it was evaluated. Therefore, as for the operator WA, the proficiency of the operation of the cargo handling vehicle 1 for picking up the luggage at a high place and the proficiency of the operation of the cargo handling vehicle 1 for placing the luggage at a high place are evaluated as having reached a predetermined standard. It is also evaluated that the proficiency of the operation of the cargo handling vehicle 1 for picking up the luggage in the place and the operation of the cargo handling vehicle 1 for placing the luggage in a low place have also reached the predetermined standard. For this reason, it is determined in step S5 that the proficiency of the operator WA has not been evaluated lower than the predetermined standard, and it is determined that there is no need to improve the operating skill of the operator WA. M is not assigned.

  On the other hand, with respect to the operator WB, it is determined in step S5 that the proficiency level related to maneuvering required for the cargo handling work D, E is evaluated lower than a predetermined standard. The cargo handling operations D and E both require the operation of the cargo handling vehicle 1 for picking up luggage at a high place. Therefore, the operator WB is evaluated that the proficiency level related to the operation of the cargo handling vehicle 1 for picking up luggage at a high place is lower than a predetermined standard. For this reason, in step S6, the handling operations J and L that require the operator WB to perform the operation whose proficiency is evaluated to be lower than the predetermined standard, that is, the operation of picking up luggage at a high place, are performed as additional cargo operations. Assigned.

  In addition, for the operator WC, it is determined in step S5 that the proficiency level related to the maneuver required for the cargo handling work I is evaluated to be lower than the predetermined standard. On the other hand, it is evaluated that the proficiency related to the maneuver required for the cargo handling work H has reached the predetermined standard. Therefore, the operator WC is evaluated that the proficiency related to the operation of the cargo handling vehicle 1 for picking up luggage in a low place is lower than a predetermined standard. For this reason, in step S6, for the operator WC, the handling operations K and M that require the operation whose proficiency level is evaluated to be lower than the predetermined reference, that is, the operation of picking up the luggage in a low place, are the additional handling operations. Assigned.

In the above embodiment, the following effects can be obtained.
(1) Based on the measurement result of the biological information of the operator W, the proficiency of the operation of the cargo handling vehicle 1 is evaluated, and based on the evaluation result, the proficiency of the operator W is evaluated as being lower than a predetermined standard. A cargo handling operation that requires a controlled operation is assigned. For this reason, by assigning the cargo handling work requiring the maneuvering evaluated as having low proficiency to the operator W who is not good at manipulating the cargo handling vehicle 1, it is possible to efficiently improve the maneuvering skill of the operator W. .

  (2) If the proficiency level is evaluated to be lower than the predetermined standard for the operator W, an additional cargo handling operation is assigned. If the proficiency level is not evaluated to be lower than the predetermined standard, the additional handling operation is performed. Is not assigned. That is, the operator W whose proficiency has been evaluated to have reached the predetermined standard can quickly complete the cargo handling work without performing any additional cargo handling work. On the other hand, for the operator W whose proficiency is evaluated to be lower than the predetermined criterion, more time for operating the cargo handling vehicle 1 can be given by allocating additional cargo handling work, and it is possible to promote improvement of the steering skill. it can.

  (3) The cargo handling work assigned to the operator W from the plurality of cargo handling works based on the information on the plurality of cargo handling works stored in the cargo work information storage device 31 and the information on the skill level stored in the operator information storage device 33. Is selected. For this reason, if the operator information storage device 33 stores the proficiency in advance, it is possible to allocate the cargo handling work based on the evaluation result of the proficiency without measuring the biological information of the operator W.

  (4) The proficiency evaluation device 32 evaluates the proficiency based on the measurement result of the pulse rate or the heart rate. According to this configuration, a pulse meter or a heart rate monitor that can be easily worn can be adopted as the biological information measuring device 2.

  (5) The proficiency evaluation device 32 evaluates the proficiency based on the change amount or the change rate of the pulse rate or the heart rate per predetermined time. According to this configuration, the proficiency level can be evaluated based on a change in the pulse rate or the heart rate using the pulse rate or the heart rate of the operator W in a normal state as a reference value.

  (6) In steps S1 and S2, the cargo handling work assignment device 34 predicts the required work time for each of the cargo handling work, and the time during which the operator W operates the cargo handling vehicle 1 exceeds the predetermined time regardless of the skill level. One or more cargo handling operations are assigned to the operator W as described above. According to this configuration, it is possible to give the operator W an opportunity to operate the cargo handling vehicle 1 for at least a predetermined time (for example, 2 hours) regardless of the proficiency level, and it is possible to suppress a decrease in the operating skill.

  The present invention is not limited to the above embodiment, and the above configuration can be appropriately changed. For example, the above embodiment may be implemented with the following modifications, or may be implemented in combination with the following modifications.

  If it is determined in step S5 that the proficiency is not lower than the predetermined criterion, that is, if the proficiency related to the maneuver required for the cargo handling work performed by the operator W has reached the predetermined criterion, in step S4. Even in the case of evaluation, additional cargo handling work may be assigned to the operator W. In this case, in order to give the operator W whose proficiency is evaluated to be lower than the predetermined criterion more time to operate the cargo handling vehicle 1, the cargo handling work allocating device 34 sets the operator W whose proficiency is evaluated to be lower than the predetermined criterion. On the other hand, as compared with the other operators W whose proficiency has reached the predetermined standard, the cargo handling work is performed so that the working time of the cargo handling work becomes longer or the workload of the cargo handling work is increased. Is preferably assigned.

  In step S6, when it is not possible to assign the operator W a cargo handling work requiring maneuvering whose proficiency is lower than the predetermined standard (for example, when there is no unassigned cargo handling work), A cargo handling operation that does not require maneuvering whose proficiency is evaluated to be lower than a predetermined standard may be assigned. That is, the invention of the present application is only required to assign, to the operator W, a cargo handling work requiring maneuvering whose proficiency is evaluated to be lower than the predetermined standard in preference to other cargo handling works. It does not deny the assignment of cargo handling operations.

  The same number of cargo handling operations does not have to be assigned to each of the plurality of operators W in step S2. Similarly, the same number of cargo handling operations need not be assigned to each of the plurality of operators W in step S6. In this case, in step S6, it is preferable to allocate more cargo handling operations to the operator W as the number of cargo handling operations requiring maneuvering whose proficiency is evaluated to be lower than the predetermined reference is increased. That is, the cargo handling work allocating device 34 allocates more cargo handling work to give the operator W more time to operate the cargo handling vehicle 1 as the number of maneuvers whose proficiency is evaluated to be lower than the predetermined reference increases. Is preferred.

  ・ Even if the proficiency level is evaluated as lower than the predetermined standard, if the proficiency level is evaluated as lower than the predetermined standard and there are few cargo operations that require maneuvering, additional cargo operations may be reduced. Alternatively, no additional cargo handling work may be assigned. That is, for example, in the above-described embodiment, for the operator WC evaluated that the proficiency of the operation related to one cargo handling work I is lower than the predetermined reference, the cargo handling work assignment device 34 assigns the same work content as the cargo handling work I. Only the included cargo handling work K may be assigned as the additional cargo handling work, or it is determined that the evaluation of the proficiency level related to the cargo handling work I is based on incorrect biological information, and the additional cargo handling work is not assigned. You may.

  The proficiency evaluation device 32 may evaluate the proficiency related to the operation of the cargo handling vehicle 1 based on the biological information other than the pulse rate and the heart rate of the operator W. That is, as long as the degree of tension of the operator W can be measured, a device other than the pulse meter and the heart rate monitor may be adopted as the biological information measuring device 2. Further, the biological information measuring device 2 may transmit the measured biological information to the management device 3 via the cargo handling vehicle 1 or may transmit the measured biological information to the management device 3 without passing through the cargo handling vehicle 1.

  -If the proficiency related to the operation of the cargo handling vehicle 1 can be evaluated, the evaluation method may be appropriately changed. For example, the proficiency evaluation device 32 maintains the number of times the measured pulse rate or heart rate reaches the pulse rate or heart rate of the operator W during tension, and maintains the pulse rate or heart rate of the operator W during tension. The proficiency may be evaluated based on time.

  The proficiency evaluation target is not limited to the operation of the cargo handling vehicle 1 for picking up luggage at a high place or a low place and the operation of the cargo handling vehicle 1 for placing luggage at a high place or a low place. For example, the handling of the cargo handling vehicle 1 for transporting the cargo over a long distance, the handling of the cargo handling vehicle 1 for traveling the cargo in a narrow passage, and the handling of the cargo handling vehicle 1 for changing the direction and transporting the cargo. The maneuver may be a proficiency evaluation target. In this case, the information on the cargo handling work stored in the cargo handling information storage device 31 includes, as the information on the work content of the cargo handling work, for example, information on the transport distance of the cargo, information on the transport space of the cargo, And information on the presence / absence of a change of direction when carrying the load.

  The proficiency evaluation device 32 also evaluates the proficiency based on the required time required for the cargo handling work by the operator W, that is, the information on the time during which the cargo handling vehicle 1 was operated and the measurement result of the biological information. Good. Specifically, for example, when the required time for the cargo handling work is longer than a predetermined time and the predetermined condition related to the measured pulse rate or heart rate is satisfied, the proficiency evaluation device 32 It may be evaluated that the proficiency related to the maneuver required for the vehicle is lower than a predetermined standard. Alternatively, the proficiency level evaluation device 32 is used for the cargo handling work when the required time for the cargo handling work is longer than a predetermined time or when a predetermined condition related to the measured pulse rate or heart rate is satisfied. It may be evaluated that the proficiency related to the determined maneuver is lower than a predetermined standard.
