It shows that.

The next delivery zone identification unit 16 shown in FIG. 3 performs a process of identifying the delivery zone to which the transportation vehicle heads next based on the operation plan information 111 stored in the transportation-related storage unit 15. Further, the next delivery zone identification unit 16 includes the cargo information 112 transmitted from the shipping base terminal 3, the loading / unloading order information 113 stored in advance in the transportation-related storage unit 15, and the transportation destination change transmitted from the in-vehicle device 2. Based on the information, it is determined whether or not there is a change in the operation plan from the operation plan information 111. When it is determined that the operation plan has been changed, the next delivery zone identification unit 16 performs a process of changing the delivery zone of the next transportation destination. Here, when there is a change in the operation plan, when the transportation of the product to the planned delivery area is stopped, when the transportation of the product to the unplanned delivery area occurs, the road condition, the weather condition This refers to the case where the driver changes the transportation route due to such reasons.

From the information recorded in the operation plan information 111, the next delivery zone identification unit 16 sets the next transportation destination to the base where the transportation of the product is not completed and the estimated arrival time is the earliest and the delivery zone. Judge.

Further, the next delivery zone identification unit 16 derives the next base to which the transport vehicle heads and the delivery zone from the loading information 112 and the loading / unloading order information 113, and delivers the base and delivery specified from the operation plan information 111. Whether or not there is a change in the transportation plan is judged by comparing with the ward. The next delivery zone identification unit 16 reads the information on the loading order and the unloading order of the corresponding transport vehicle from the loading / unloading order information 113, and the "loading order" is "previous" and the "unloading order" is ". Acquires information on whether "after" or "loading order" is "after" and "unloading order" is "before".

When the "loading order" is "before" and the "unloading order" is "after", the next delivery zone identification unit 16 determines the base and delivery zone of the product with the slowest loading time from the loading information 112. Judged as the destination of transportation. When the "loading order" is "after" and the "unloading order" is "before", the next delivery zone identification unit 16 selects the base and delivery zone of the product having the earliest loading time from the loading information 112. Judged as the destination of transportation. In the example of the transport vehicle No. 1 with the loading information 112 shown in FIG. 5 and the loading / unloading order information 113 shown in FIG. 6, the “loading order” of the loading / unloading order information 113 is “front” and “unloading”. Since the "order" is "after", the next delivery zone identification unit 16 finds that the c delivery zone of the factory A, which is the transport destination of the part 7 having the slowest loading time, is the next transport destination from the cargo information 112. Derive that there is.

Next, the next delivery zone identification unit 16 compares the delivery zone of the base specified from the operation plan information 111 with the delivery zone of the base derived from the cargo information 112 and the loading / unloading order information 113, and operates. Determine if there has been a change in the plan. If each delivery zone is the same, the next delivery zone identification unit 16 determines that there is no change in the operation plan, and determines the base with the earliest estimated arrival time of the operation plan information 111 and its delivery zone according to the operation plan information 111. Judge as the next destination. If each delivery zone is different, the next delivery zone identification unit 16 determines that the operation plan has been changed, and transports the delivery zone of the base derived from the loading information 112 and the loading / unloading order information 113 to the next transportation. Judge that it is ahead.

Further, when the next delivery zone identification unit 16 receives the transportation destination change information from the in-vehicle device 2, it determines that the operation plan has been changed, and sets the base and delivery zone indicated by the transportation destination change information as the next transportation destination. Judge.

The vehicle approach determination unit 17 delivers the transport vehicle based on the vehicle position information indicating the current latitude and longitude of the transport vehicle transmitted from the in-vehicle device 2 and the delivery zone information 114 stored in the transport-related storage unit 15. It is determined whether or not the vehicle has approached the ward, and if it is determined that the ward has been approached, a process of transmitting an approach notification to the worker terminal 4 of the ward is performed.

When the vehicle approach determination unit 17 specifies the next delivery zone of the transport vehicle by the next delivery zone identification unit 16 and receives the notification, the vehicle approach determination unit 17 receives the notification, and the position of the delivery zone specified by the next delivery zone identification unit 16 from the delivery zone information 114. Get information and distance thresholds. The vehicle approach determination unit 17 calculates the distance between the vehicle and the delivery zone from the latitude and longitude included in the vehicle position information received from the vehicle-mounted device 2 and the latitude and longitude of the delivery zone. The vehicle approach determination unit 17 compares the calculated distance with the threshold value, and if it is determined that the calculated distance is less than the threshold value of the delivery area information 114, the vehicle approach notification data is generated.

The vehicle approach determination unit 17 acquires the worker terminal ID of the corresponding delivery zone from the delivery zone information 114, and transmits the generated approach notification data to the communication unit 14. The communication unit 14 transmits the approach notification data to the worker terminal 4 of the delivery zone specified by the next delivery zone identification unit 16.

When the "transmission type" of the delivery area information 114 is all at once, the approach notification data is transmitted to all the registered worker terminals 4, and if the "transmission type" has priority, the priority is given. Data is transmitted to the expensive worker terminal 4. In an example of the delivery zone information 114 shown in FIG. 7, when the approach notification data is transmitted to the worker terminal 4 in the delivery zone a of the base A, the "transmission type" has priority, so the worker with the highest priority. The terminal ID will be transmitted to the terminal of 7. The format of the notification is, for example, e-mail, notification by SMS, push notification, or the like.

Further, the transmission of the approach notification data is repeated until the response information from the worker terminal 4 is received. When the vehicle approach determination unit 17 transmits the transmission of the approach notification data, the vehicle approach determination unit 17 stores the transmission time and receives the response information from the worker terminal 4 until the retransmission interval time stored in the delivery zone information 114 elapses. .. When the response information is not received until the retransmission interval time elapses, the approach notification data is transmitted to the worker terminal 4 again to the approach notification data. When the "transmission type" has priority, the approach notification data may be transmitted again to the worker terminal 4 that has transmitted the data, or may be transmitted to the terminal with the worker terminal ID having the next highest priority.

The control unit 25 adds the measured date and time information to the total measured latitude / longitude information and transmits the information to the communication unit 22. The communication unit 22 transmits the received information to the transportation management device 1 via the network 5.

The input unit 21 accepts the input of the transportation destination change by the driver of the transportation vehicle and the input of the information indicating that the transportation is completed. The input unit 21 is used when the driver determines that the vehicle will be transported to a destination different from the operation plan information 111 due to, for example, road conditions, weather, or the like. From the list of bases and delivery areas displayed on the display unit 24, the driver inputs a new base and delivery area to be next to the input unit 21. The input method may be, for example, a method of selecting from the list of bases and delivery areas displayed on the display unit 24 from a pull-down menu, a method of selecting with a radio button, a method of inputting a number corresponding to the base and the list, and the like. Absent. The control unit 25 generates transportation destination change information including information on a new base and delivery area input by the driver and information on the input date and time, and transmits the information to the communication unit 22.

Obtain information on bases, delivery areas, etc. The cargo information generation unit 34 generates cargo information from the information acquired by the acquisition unit 30 and the date and time of reading, and stores the cargo information in the storage unit 31. The communication unit 32 transmits the generated cargo information to the transportation management device 1 via the network 5.

Next, the functional configuration of the worker terminal 4 will be described with reference to FIG. The worker terminal 4 is used by a worker who unloads a product in a delivery area of a base. The worker terminal 4 has a communication unit 40 that receives an approach notification from the transportation management device 1 and transmits response information to the approach notification, and an input unit 41 that receives response information input by the worker to the received approach notification. , A display unit 42 that displays approach notification information, a storage unit 43 that stores information received by the communication unit 40, and a worker terminal 4 including the communication unit 40, an input unit 41, a display unit 42, and a storage unit 43. A control unit 44 for controlling the operation is provided. The worker terminal 4 may be a communication device such as a smartphone, a wristwatch-type terminal, or a smart watch.

The communication unit 40 receives the approach notification transmitted from the transportation management device 1, and transmits to the transportation management device 1 the response information to the approach notification such as whether or not the unloading can be performed, which the operator has input to the input unit 41. To do. The display unit 42 displays the approach notification information received by the communication unit 40. The input unit 41 receives input of response information from the worker in response to the approach notification. The operator is transmitted information such as YES / NO, possible / impossible, etc. displayed on the display unit 42 to inform the driver that the operator is ready to perform the unloading operation.

Subsequently, the operation of the transportation management system 100 will be described. The main operation of the transportation management system 100 is that the transportation management device 1 identifies the next delivery zone for each transportation vehicle, and when the distance to the delivery zone meets the standard, approaches the worker's terminal. It is an operation to notify.
Therefore, first, the next delivery zone identification process in which the transportation management device 1 specifies the delivery zone to which each transportation vehicle moves next will be described with reference to FIG.

When the product is loaded into the transportation vehicle at the shipping base and the next delivery zone identification unit 16 receives the cargo information 112 from the shipping base terminal 3 or receives the notification of the completion of transportation from the in-vehicle device 2, FIG. Start the process of identifying the next delivery zone to which the indicated transport vehicle is heading.

First, the next delivery zone identification unit 16 acquires the operation plan information 111 from the transportation-related storage unit 15 (step S11), and from the bases and delivery zones in the operation plan information 111 where the transportation of the product has not been completed. , The base and the delivery zone with the earliest estimated arrival time are specified as the next transportation destinations (step S12), and are stored in the vehicle transportation destination information 116 (step S13).

Next, the next delivery zone specifying unit 16 acquires the cargo information 112 and the loading / unloading order information 113 from the transportation-related storage unit 15 (step S14), and from the loading information 112 and the loading / unloading order information 113. , Performs the process of deriving the next transportation destination base and delivery area. In the loading / unloading order information 113, the "loading order" is "before" and the "unloading order" is "after", or the "loading order" is "after" and "unloading" of the corresponding transport vehicle. Either "order" is "before" or "before" is memorized. When the “loading order” is “before” and the “unloading order” is “after” in the acquired loading / unloading order information 113 (step S15; YES), the next delivery zone specifying unit 16 provides the loading information. From 112, the base of the product with the slowest loading time and the delivery area are derived as the next transportation destination (step S16).

When the “loading order” is “after” and the “unloading order” is “before” in the acquired loading / unloading order information 113 (step S15; NO), the next delivery zone specifying unit 16 provides the loading information. From 112, the base and delivery area of the product with the fastest loading time are derived as the next transportation destination (step S17).

Next, the next delivery zone identification unit 16 has the same base and delivery zone stored in the vehicle transportation destination information 116, and the base and delivery zone derived from the cargo information 112 and the loading / unloading order information 113. If it is determined that they are the same (step S18; YES), it is determined that the base and the delivery area stored in the vehicle transportation destination information 116 are the next transportation destinations.

The next delivery zone identification unit 16 includes the base and delivery zone stored in the vehicle transportation destination information 116 in step S13, that is, the base and delivery zone set based on the operation plan information 111, the cargo information 112, and the loading / unloading. When it is determined from the order information 113 that the base derived in step S16 or S17 and the delivery area are not the same (step S18; NO), the operation plan set in the operation plan information 111 has been changed. , It is determined that the base and delivery zone derived from the loading information 112 and the loading / unloading order information 113 are the next transportation destinations (step S19), and the vehicle transportation destination information 116 is modified (step S20).

After that, the next delivery zone identification unit 16 ends the process unless the in-vehicle device 2 notifies the change of the transportation destination (step S21; NO). When the next delivery zone identification unit 16 receives the notification of the change of transportation destination from the in-vehicle device 2 (step S21; YES), the next delivery zone identification unit 16 determines that the base and delivery zone included in the notification of the change of transportation destination are the next delivery zone (step S21; YES). Step S22), the vehicle transport destination information 116 is modified (step S23), and the process ends.

In this way, for each transport vehicle, the next delivery zone to move is confirmed and updated as necessary. This makes it possible to respond to sudden changes in the operation plan.

Subsequently, FIG. 11 showing the flow of the vehicle approach determination process for the process of determining that the transport vehicle has approached the delivery area and transmitting the approach notification to the worker terminal 4 by the vehicle approach determination unit 17. It will be explained with reference to.

When the next delivery zone identification unit 16 specifies the next delivery zone to which the transport vehicle is heading, the next delivery zone identification unit 16 notifies the vehicle approach determination unit 17 to that effect. Upon receiving the notification from the next delivery zone identification unit 16, the vehicle approach determination unit 17 starts the vehicle approach determination process shown in FIG. 11, and the vehicle transportation destination information 116 and the delivery zone information 114 stored in the transportation-related storage unit 15. (Step S31).

When the vehicle approach determination unit 17 receives the vehicle position information indicating the current position of the transportation vehicle from the in-vehicle device 2 (step S32), the vehicle approach determination unit 17 stores the latitude and longitude included in the vehicle position information and the date and time when the vehicle position information is acquired in the transportation-related storage. It is stored in the approach notification history information 115 of the unit 15 (step S33). After that, the vehicle approach determination unit 17 calculates the distance from the latitude and longitude of the received vehicle position information and the latitude and longitude of the delivery zone recorded in the delivery zone information 114 (step S34). After that, the vehicle approach determination unit 17 reads the threshold value from the delivery zone information 114 and determines whether or not the calculated distance is less than the threshold value (step S35).

When the vehicle approach determination unit 17 determines that the calculated distance is equal to or greater than the threshold value (step S35; NO), the vehicle approach determination unit 17 does not perform the process until the next vehicle position information is received. When the vehicle approach determination unit 17 determines that the calculated distance is less than the threshold value (step S35; YES), the vehicle approach determination unit 17 acquires the worker terminal ID and transmission type information of the delivery zone specified from the delivery zone information 114 (step S35; YES). S36). After that, the vehicle approach determination unit 17 generates approach notification data, causes the communication unit 14 to transmit the approach notification data for the worker terminal 4 of the acquired worker terminal ID, and stores the transmission time (step S37). When the transmission item of the delivery zone information 114 is defined as "simultaneous", the approach notification data is transmitted to all the worker terminals 4 registered in the delivery zone information 114, and "priority" is sent. If it is defined as, the approach notification data is transmitted to the worker terminal 4 having a higher priority of the “worker terminal”. When the approach notification data is transmitted, the vehicle approach determination unit 17 stores "1" indicating that the approach notification data has been transmitted in the approach notification history information 115 of the transportation-related storage unit 15 (step S38).

When the vehicle approach determination unit 17 transmits the approach notification data, the vehicle approach determination unit 17 receives the response information from the worker terminal 4 (step S39). When the vehicle approach determination unit 17 receives the response information from the worker terminal 4 (step S40; YES), the vehicle approach determination unit 17 displays “2” indicating that the response information from the worker terminal 4 has been received in the transportation-related storage unit 15. The approach notification history information 115 is stored (step S42), and the vehicle approach determination process is completed. On the other hand, when the vehicle approach determination unit 17 does not receive the response information in response to the transmitted approach notification (step S40; NO), the time of the retransmission interval of the delivery zone information 114 elapses from the time when the approach notification data is transmitted. Until (step S41; NO), the response information is accepted.

When the vehicle approach determination unit 17 does not receive the response information (step S40; NO) and determines that the retransmission interval time of the delivery zone information 114 has elapsed from the time when the approach notification data is transmitted (step S41; YES), Retransmit the approach notification data.

As described above, the transportation management device 1 includes the operation plan information 111 and the loading / unloading order information 113 stored in the transportation-related storage unit 15, the loading information 112 transmitted from the worker terminal 4, and the in-vehicle device 2. Identify the next delivery zone for the transport vehicle based on the destination change information sent by. Further, the transportation management device 1 calculates the distance from the vehicle position information received from the in-vehicle device 2 and the position information of the delivery zone information 114, and registers the calculated distance and the distance threshold value in the delivery zone information 114. It is determined whether or not to notify the approaching worker terminal 4 of the approach. In this way, the transport management device 1 flexibly responds to the change of the immediately preceding transport plan for the worker in the delivery zone to which the transport vehicle transporting between the bases having a plurality of delivery zones heads, and the transport vehicle Can be notified in advance of the arrival of.

Further, the approach notification may be transmitted when other predetermined conditions are met, not limited to the distance or time.

In the above embodiment, the time from receiving the notification to the arrival of the transport vehicle becomes extremely short, such as when the interval between delivery areas is short or when the unloading work in the delivery area does not require time. It may end up. In order to avoid such an event, for example, in step S13, the transport destinations up to n (n is a natural number of 2 or more) are specified and stored in the vehicle transport destination information 116, and in step S19, up to n destinations are stored. It is determined whether there is a change in the transportation destination, the vehicle transportation destination information 116 is updated as necessary in step S20, the estimated time to the n destinations ahead is obtained in step S35, and if it is below the threshold value. , May be notified in step S37. For the second and subsequent delivery areas, the unloading time in the previous delivery area will be taken into consideration in the estimated time.
