It is a forklift. The cargo handling vehicle 1 operating in the manned operation mode receives information related to the cargo handling work assigned to the operator W boarding the cargo handling vehicle 1 from the management device 3, and receives the received information related to the cargo handling work to the operator W. By presenting, the operator W is made to perform a cargo handling operation using the cargo handling vehicle 1. For example, a display (not shown) provided in the cargo handling vehicle 1 performs the presentation of information related to the cargo handling work to the operator W. Also, the cargo handling vehicle 1 operating in the unmanned operation mode receives information related to the cargo handling work assigned to the cargo handling vehicle 1 from the management device 3 and operates autonomously based on the received information related to the cargo handling work. Cargo handling work at In addition, the cargo handling vehicle 1 transmits information related to the progress status of the cargo handling work to the management device 3.

  The biological information measuring device 2 is a wearable device that measures biological information of an operator W who is maneuvering (operating) the cargo handling vehicle 1, and uses a pulse rate or a heart rate per predetermined time as the biological information of the operator W. taking measurement. The biological information measuring device 2 transmits the measured biological information of the operator W to the management device 3.

  The management device 3 is configured to be able to communicate with a plurality of cargo handling vehicles 1 and manages cargo handling work using the cargo handling vehicles 1. The management device 3 transmits to each of the plurality of cargo handling vehicles 1 information related to the cargo handling work performed using the cargo handling vehicle 1. Further, the management device 3 receives information related to the progress status of the cargo handling work from the cargo handling vehicle 1 and receives the biological information of the operator W from the biological information measuring device 2.

  The communication relay device 4 relays communication between the cargo handling vehicle 1 and the management device 3. The communication relay device 4 is configured to be communicable with the cargo handling vehicle 1 wirelessly, and is configured to be communicable with the management device 3 by wire or wirelessly.

  The cargo handling work allocation system S includes a cargo handling work information storage device 31, a proficiency level evaluation device 32, an operator information storage device 33, and a cargo handling work allocation device 34 as elements constituting the management device 3. .

  The cargo handling work 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 work information storage device 31 stores, as information related to the cargo handling work, information related to the loading position and the loading position, information related to the travel route when the cargo is transported, etc. for each cargo handling work. It is stored in association with.

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

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

  The cargo handling work allocating device 34 uses the cargo handling vehicle 1 with respect to an operator W that controls 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 work. Assign one or more cargo handling operations. Then, the cargo handling work allocation 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. Send information. Also, the cargo handling work allocation device 34 assigns to the operator W who is the subject of evaluation of the proficiency level based on the proficiency level evaluation result related to the handling of the cargo handling vehicle 1, that is, the proficiency level evaluated by the proficiency level evaluation device 32. On the other hand, a cargo handling operation that requires maneuvering evaluated as having a lower level of proficiency than a predetermined standard is preferentially assigned. The detailed operation of the cargo handling work assignment device 34 will be described below with reference to FIG.

With reference to FIG. 2, the flow when the cargo handling work allocation device 34 allocates the cargo handling work will be described.
First, the cargo handling work allocation device 34 is based on the information related to the cargo handling work acquired from the cargo handling work information storage device 31 and the information related to the cargo handling work performed by the operator W acquired from the operator information storage device 33 in the past. W predicts the time required for each of the plurality of cargo handling operations (step S1).

  Then, one or more cargo handling work allocating devices 34 are provided to the operator W so that the time during which the operator W steers the cargo handling vehicle 1 (driving time) exceeds a predetermined time (for example, 2 hours). Is assigned (step S2). That is, the cargo handling work allocating device 34 performs the cargo handling work on the operator W so that the operator W steers the cargo handling vehicle 1 for at least a predetermined time and performs the cargo handling work based on the work required time predicted in step S1. assign. The cargo handling work allocation device 34 that allocates the cargo handling work to the operator W transmits information related to the allocated cargo handling work to the cargo handling vehicle 1 that the operator W controls. Also, the cargo handling work allocation device 34 allocates the remaining cargo handling work that has not been assigned to the operator W to the cargo handling vehicle 1 in the unmanned operation mode, and transmits information related to the cargo handling work assigned to the cargo handling vehicle 1. . In this way, the operator W who controls 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 becomes the cargo handling vehicle 1. The biological information (pulse rate or heart rate) of the operator W who is maneuvering is measured.

  Then, based on the information related to the progress status of the cargo handling work received from the cargo handling vehicle 1, the cargo handling work allocation device 34 determines whether or not the cargo handling work assigned to the operator W in Step S2 is completed (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, the cargo handling work assignment device 34 does not perform the following step S4 and subsequent steps until the cargo handling work assigned to the operator W is completed.

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

  Next, based on the evaluation result of the proficiency level stored in the operator information storage device 33, the cargo handling work allocation device 34 determines whether or not the proficiency level related to the operation of the cargo handling vehicle 1 by the operator W has been evaluated lower than a predetermined standard. Judgment is made (step S5).

  When the handling work allocation device 34 determines in step S5 that the proficiency level related to the handling of the cargo handling vehicle 1 has not been evaluated to be lower than the predetermined standard, that is, the proficiency level related to the handling required for the handling work performed by the operator W. When it is evaluated in step S4 that the degree has reached the predetermined standard, it is not necessary to improve the handling skill of the operator W, and no additional cargo handling work is assigned to the operator W. The operator W who has completed the cargo handling work gets off the cargo handling vehicle 1 and switches to the unmanned operation mode.

  On the other hand, when it is determined in step S5 that the proficiency level related to the handling of the cargo handling vehicle 1 is evaluated to be lower than the predetermined standard, the cargo handling work allocation device 34 relates to the handling required for the handling work performed by the operator W. If the proficiency level is evaluated to be lower than the predetermined standard, one or more additional cargo handling operations are assigned to the operator W on the assumption that it is necessary to improve the operator W's handling skill (step S6). Specifically, the cargo handling work allocation device 34 is based on a plurality of cargo handling work information stored in the cargo handling work information storage device 31 and a plurality of information related to proficiency stored in the operator information storage device 33. A cargo handling operation to be additionally allocated to the operator W from the cargo handling operation is selected. At this time, the cargo handling work allocating device 34 selects a cargo handling work that requires a maneuvering that is evaluated as having a proficiency level lower than a predetermined standard as an additional cargo handling work. The cargo handling work allocation device 34 that allocates 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. Thus, the operator W who is evaluated that the proficiency level for the predetermined maneuver is lower than the predetermined standard, 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, the evaluation method of the skill level which concerns on the operation of the cargo handling vehicle 1 of the operator W is demonstrated. 3A shows an example of a change in the pulse rate of an operator W who is highly evaluated for proficiency, and FIG. 3B shows an example of a change in the pulse rate of an operator W who is evaluated for low proficiency. Represents.

  As shown in FIG. 3 (A), an operator W who has a high level of proficiency in handling the cargo handling vehicle 1 does not become nervous due to the handling of the cargo handling vehicle 1 when picking up the luggage or placing the luggage, for example. There is no significant variation in the W pulse. Therefore, if the measured pulse rate or heart rate per predetermined time of the operator W is close to the pulse rate or heart rate (for example, 80) of the operator W in normal times, the proficiency level evaluation device 32 may handle the handling vehicle of the operator W. It is evaluated that the proficiency level related to the operation of 1 has reached a predetermined standard. Specifically, the proficiency level evaluation apparatus 32, for example, when the measured pulse rate or heart rate is maintained below 100, the measured pulse rate or heart rate change amount (difference between the minimum value and the maximum value) is 20. If it is less than or when the measured pulse rate or the rate of change of the heart rate (percentage of the maximum value with the minimum value being 100%) is less than 125%, the proficiency has reached the predetermined standard And evaluate.

  On the other hand, as shown in FIG. 3B, the operator W who has a low level of proficiency in maneuvering the cargo handling vehicle 1 may be nervous about maneuvering the cargo handling vehicle 1 when picking up a baggage or placing a baggage. A large fluctuation occurs in the pulse of the operator W. Therefore, the proficiency level evaluation device 32 determines that the pulse rate or heart rate of the operator W measured per predetermined time is higher than the pulse rate or heart rate (for example, 80) of the operator W in normal times and is in tension. If it approaches a number (for example, 100), it is evaluated that the proficiency level of the operator W regarding the handling of the cargo handling vehicle 1 is lower than a predetermined standard. Specifically, the proficiency level evaluation apparatus 32 measured, for example, when the measured pulse rate or heart rate reached 100, when the measured pulse rate or heart rate change amount was 20 or more, or measured. If the rate of change of the pulse rate or heart rate is 125% or more, it is evaluated that the proficiency level is lower than the predetermined standard.

  With reference to FIG. 4, the Example which concerns on the allocation of the cargo handling work based on the evaluation result of the skill level in step S5, S6 is demonstrated. In the cargo handling work assignment system S according to the present embodiment, the cargo handling work assignment device 34 assigns the cargo handling works A to I to the three operators WA to WC in step S2, and assigns the remaining cargo handling works J to M. Assign in step S6.

  In this embodiment, in step S2, cargo handling operations A to C are assigned to the operator WA, cargo handling operations D to F are assigned to the operator WB, cargo handling operations G to I are assigned to the operator WC, and a cargo handling operation information storage device is provided. 31 is premised on storing information related to the cargo handling operation shown in FIG. As shown in FIG. 4 (A), the information related to the cargo handling work includes information related to the height of the loading position and the loading position as information related to the work content of the cargo handling work. In the column of the loading position and loading position in FIG. 4A, “high” indicates a high place and “low” indicates a low place. Therefore, for example, the cargo handling operation A requires the handling of the cargo handling vehicle 1 for picking up a load at a high place at the time of unloading (loading), and the load at a high place at the time of loading (unloading). It is necessary to maneuver the cargo handling vehicle 1 for placing, and the cargo handling operation C requires maneuvering of the cargo handling vehicle 1 for picking up the low load at the time of picking up, and cargo handling for placing the load at the low location at the time of loading. The vehicle 1 needs to be operated.

  Further, in this embodiment, in step S4, based on the biological information of the operators WA to WC when performing the cargo handling work A to I, the proficiency level related to the handling of the cargo handling vehicle 1 for each cargo handling work A to I is determined. The operator information storage device 33 that is evaluated includes information related to the operator WA shown in FIG. 4B, information related to the operator WB shown in FIG. 4C, and information related to the operator WC shown in FIG. It is assumed that information is stored. In the proficiency level columns in FIGS. 4B to 4D, “◯” indicates that the proficiency level has reached a predetermined standard, and “×” indicates that the proficiency level is lower than the predetermined standard. It shows that it was evaluated. Therefore, the operator WA is evaluated as having reached a predetermined standard in the level of proficiency in handling the handling vehicle 1 for picking up loads at high places and handling the handling vehicle 1 for placing loads in high places. The proficiency level related to the handling of the cargo handling vehicle 1 for picking up the luggage at the place and the handling of the cargo handling vehicle 1 for placing the luggage in the low place is evaluated to have reached a predetermined standard. For this reason, it is determined in step S5 that the proficiency level of the operator WA has not been evaluated to be lower than the predetermined standard, so that it is not necessary to improve the operator WA's handling skills. M is not assigned.

  On the other hand, for the operator WB, it is determined in step S5 that the proficiency level related to the maneuvering required for the cargo handling operations D and E has been evaluated to be lower than a predetermined standard. The cargo handling operations D and E both require the handling of the cargo handling vehicle 1 to pick up a load at a high place. Therefore, it is evaluated that the operator WB has a lower level of proficiency regarding the handling of the cargo handling vehicle 1 for picking up loads at high places than the predetermined standard. For this reason, in step S6, the cargo handling operations J and L that require the operator WB to evaluate the skill level to be lower than the predetermined standard, that is, the handling of picking up the high load, are added as additional cargo handling operations. Assigned.

  Further, for the operator WC, it is determined in step S5 that the proficiency level related to the maneuvering required for the cargo handling work I has been evaluated to be lower than a predetermined standard. On the other hand, it is evaluated that the proficiency level related to the maneuvering required for the cargo handling work H has reached a predetermined standard. Therefore, it is evaluated that the operator WC has a lower level of proficiency regarding the handling of the cargo handling vehicle 1 for picking up a low load than a predetermined standard. For this reason, in step S6, the handling operations K and M that require the operator WC to evaluate the skill level to be lower than the predetermined standard, that is, the operation to pick up the low load, are added as 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 level related to the handling of the cargo handling vehicle 1 is evaluated, and based on the evaluation result, the proficiency level is evaluated to be lower than a predetermined standard for the operator W. Cargo handling operations requiring assigned maneuvers are assigned. For this reason, it is possible to efficiently improve the operator W's maneuvering skill by allocating a cargo handling operation that requires maneuvering evaluated as having low proficiency to the operator W who is not good at maneuvering the cargo handling vehicle 1. .

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

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

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

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

  (6) In steps S1 and S2, the cargo handling work allocating device 34 predicts the time required for each cargo handling work, and the time that the operator W operates the cargo handling vehicle 1 exceeds a predetermined time regardless of the level of proficiency. As described above, one or more cargo handling operations are assigned to the operator W. According to this configuration, regardless of the level of proficiency, the operator W can be given an opportunity to steer the cargo handling vehicle 1 for at least a predetermined time (for example, 2 hours), and a reduction in maneuvering skill can be suppressed.

  The present invention is not limited to the above embodiment, and the above configuration can be changed as appropriate. For example, the embodiment described above may be modified as follows, or may be implemented by combining the following modifications.

  If it is determined in step S5 that the proficiency level has not been evaluated lower than the predetermined standard, that is, if the proficiency level related to the maneuvering required for the cargo handling operation performed by the operator W has reached the predetermined standard, in step S4 Even when it is evaluated, an additional cargo handling operation may be assigned to the operator W. In this case, in order to give a lot of time for maneuvering the cargo handling vehicle 1 to the operator W evaluated that the proficiency level is lower than the predetermined standard, the cargo handling work allocation device 34 has the operator W evaluated that the proficiency level is lower than the predetermined standard. On the other hand, the cargo handling work is performed so that the working time of the cargo handling work becomes longer or the work amount of the cargo handling work is larger than that of the other operator W evaluated that the proficiency level has reached the predetermined standard. Is preferably assigned.

  In step S6, when it is not possible to assign a handling operation that requires a maneuver that is evaluated as having a proficiency level lower than a predetermined standard to the operator W (for example, when there is no unallocated handling operation), You may assign the cargo handling operation | work which does not require the operation evaluated that the skill level is lower than a predetermined standard. That is, the invention of the present application is not limited as long as it assigns a priority to the operator W with a cargo handling operation that requires maneuvering evaluated as having a lower proficiency level than a predetermined standard compared to other cargo handling operations. There is no denying the assignment of cargo handling work.

  -It is not necessary to assign the same number of cargo handling operations to each of the plurality of operators W in step S2. Similarly, it is not necessary to assign the same number of cargo handling operations 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 cargo handling operations requiring the maneuvering evaluated as having a lower proficiency level than the predetermined standard. That is, the cargo handling work allocation device 34 allocates a lot of cargo handling work in order to give more time for maneuvering the cargo handling vehicle 1 to the operator W as the number of maneuvers evaluated as having a lower proficiency level than the predetermined standard. It is preferable.

  ・ Even if the proficiency level is evaluated to be lower than the predetermined standard, if there are few cargo handling operations that require maneuvering evaluated as the proficiency level is lower than the predetermined standard, the additional cargo handling work 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 that is evaluated that the proficiency level of the operation related to one cargo handling work I is lower than a predetermined standard, the cargo handling work allocating device 34 has the same work content as the cargo handling work I. Only the included cargo handling work K may be assigned as an additional cargo handling work, or it is determined that the proficiency level of the cargo handling work I is based on incorrect biological information, and no additional cargo handling work is assigned. May be.

  The proficiency level evaluation device 32 may evaluate the proficiency level related to the operation of the cargo handling vehicle 1 based on the pulse rate of the operator W and biological information other than the heart rate. 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 employed as the biological information measuring device 2. 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 be transmitted to the management device 3 without passing the cargo handling vehicle 1.

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

  The proficiency level evaluation target is not limited to the handling of the cargo handling vehicle 1 for picking up loads at high places or low places and the handling of the handling vehicle 1 for placing luggage at high places or low places. For example, the handling of the cargo handling vehicle 1 for transporting the cargo for a long distance, the handling of the cargo handling vehicle 1 for transporting the cargo by traveling in a narrow passage, and the handling of the cargo handling vehicle 1 for transporting the cargo by changing direction. Maneuvering may be an evaluation target of proficiency. In this case, the information related to the cargo handling work stored in the cargo handling work information storage device 31 includes, for example, information related to the cargo handling distance, information related to the cargo handling space, Information regarding whether or not to change the direction of the package is included.

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