In distribution bases such as factories and distribution warehouses, there may be multiple locations (hereinafter referred to as delivery areas) where unloading operations are performed within one base. In this case, multiple districts are often located close to each other. In this case, when an approach notification is issued by the approach notification device described in Patent Document 1, the approach notification is simultaneously sent to workers in a plurality of storage areas that are close to each other. In this case, some of the workers who received the approach notice have to wait until the unloading work at the previous delivery area is completed. On the other hand, if the distance used as the standard for the approach notification is set short, the approach notification will not be made until just before the arrival of the transportation vehicle, and the worker will have to wait to unload until the worker arrives at the delivery area.

In addition, in actual transportation situations, pre-prepared transportation plans may be changed suddenly due to road conditions, weather, shipping conditions, etc., so we can flexibly respond to last-minute changes in transportation plans and notify you of the approach. You are required to do the following.

The present invention has been made in view of the above-mentioned problems, and aims to provide advance notification of the arrival of a transport vehicle in a manner that flexibly responds to changes in transport plans and multiple delivery areas in close proximity. .

If there is only one storage area within the base where cargo is unloaded, the "Delivery area" item may be left blank or may contain the same information as the "base". The items "estimated arrival time" and "estimated departure time" are used by the next delivery area identification unit 16, which will be described later, to specify the next delivery area of the transport vehicle. , or if they are arranged in descending order, the "scheduled departure time" and "scheduled arrival time" items may not be included.

In the example of Figure 4, for example, after loading products at the shipping base, car No. 1 first arrives at delivery area a of warehouse C at 10:30, unloads the cargo, leaves at 10:45, and then Arrived at delivery area c of factory A at 13:00, unloaded the cargo, departed at 13:15, arrived at delivery area b of the same factory A at 13:20, and after unloading, at 13:35. Departing... ．． ．． This indicates that this is the plan. The current transportation status indicates that transportation has been completed in warehouse C's storage area a and is now heading to storage area c of factory A.

The cargo information 112 shown in FIG. 3 is information indicating the order in which products that have been loaded onto a transportation vehicle at a shipping base, but whose transportation has not yet been completed, are loaded onto the transportation vehicle. The cargo information 112 is information that is generated by the shipping base terminal 3 and transmitted to the transportation management device 1 when a product is loaded onto a transport vehicle at the shipping base. Further, when the communication unit 14 receives the transportation completion notification from the on-vehicle device 2, the control unit 10 deletes the item of the product whose transportation has been completed. Thereby, the cargo information 112 is updated according to the transportation status. The cargo information 112 is used when determining whether there is a change in the transportation plan from the operation plan information 111 in a process of determining the next delivery area of the transport vehicle by the next delivery area identification unit 16, which will be described later.

FIG. 5 shows an example of cargo information 112. The cargo information 112 shown in FIG. 5 includes "vehicle" indicating the name of the transportation vehicle, "product name" indicating the name of the product being transported, "quantity" indicating the number of products being transported, and the name of the base to which the product is being transported. It has information such as "base" indicating the location, "delivery area" indicating the name of the delivery area where products are unloaded within the base, and "loading time" indicating the time when the product was loaded onto the transport vehicle. In an example of the cargo information 112 shown in FIG. 5, 200 parts 1 destined for delivery area c of factory B are loaded onto transport vehicle No. 1 at 6:51, and 300 pieces of parts 2 of factory B destined for delivery area b are loaded onto transport vehicle No. 1. 200 parts 3 for delivery area A of factory B were loaded at 6:53. ．． ．． Indicates that it has been loaded.

The items "vehicle", "product name", "base", and "delivery area" are not limited to names, and may be any information that identifies them. Further, if there is only one storage area for unloading cargo within one base, the item "Delivery area" may be left blank, or the same information as the "base" may be provided.

The loading and unloading order information 113 shown in FIG. 3 is information indicating whether products are loaded and unloaded from the front of the transportation vehicle or from the back. The loading and unloading order information 113 is used to obtain the unloading order of products from the cargo information 112 in a process of determining the next delivery area of the transport vehicle by the next delivery area identifying unit 16, which will be described later.

FIG. 6 shows an example of the loading and unloading order information 113. The loading and unloading order information 113 shown in FIG. It has a "unloading order" item that indicates whether products are unloaded from the front of the vehicle or from the back. In this embodiment, the loading/unloading order information 113 includes "loading order" being "front" and "unloading order" being "back", or "loading order" being "back" and "unloading". It is assumed that either one of the "download order" is "previous" is stored. In the example of the loading and unloading order information 113 shown in FIG. 6, for example, in transport vehicle No. 1, loading is performed from the front of the vehicle and unloading is performed from the rear.

The delivery area information 114 in FIG. 3 includes the location of each delivery area, the distance threshold between the transport vehicle and the delivery area at which the vehicle approach determination unit 17 determines to send an approach notification, and the person in charge of each delivery area on the day of transportation. This information indicates the worker terminal ID of the worker who is sending the notification, the notification method of the approach notification, the retransmission interval, etc. The delivery area information 114 is used when the vehicle approach determination unit 17 determines whether the transportation vehicle is approaching the next delivery area and determines the worker terminal 4 to which the approaching notification will be sent and the notification method. used for.

FIG. 7 shows an example of the district information 114. The delivery area information 114 shown in FIG. , "Threshold value" indicating the distance threshold between the vehicle and the delivery area for determining that the vehicle has approached the delivery area, "Worker terminal ID" indicating the identification number of the worker terminal 4 that transmits the approach notification, and " When multiple terminals are registered in "Worker Terminal ID", it indicates whether to send notifications to all the registered worker terminals 4 or preferentially send notifications to a specific worker terminal 4. It has information such as ``transmission type'' and ``retransmission interval'' indicating the time interval at which approach notifications are retransmitted.

In the example of Figure 7, for example, if the location is A-ku of base A, the latitude is 34.9653035, the longitude is 138.4188175, and the distance threshold for determining that the vehicle has approached is 5 km, and it is determined that the vehicle has approached. At times, notification is given in the priority order of ID7, ID8, and ID9, indicating that the retransmission interval is 30 seconds.

The items "base", "delivery area", and "transmission type" are not limited to names, and may be any identifying information. When a plurality of worker terminal IDs are included in the "worker terminal ID", they may be separated by commas, spaces, tabs, etc. in order of priority for notification of approach notifications, but the IDs are not limited to these. The "threshold value" and the "retransmission interval" may be different values for each delivery area, or may be the same value.

The approach notification history information 115 shown in FIG. 3 is information indicating the history of whether or not an approach notification regarding the current position of the transport vehicle received from the on-vehicle device 2 has been sent, and whether there has been a response from the worker terminal 4 to the approach notification. The approach notification history information 115 is generated by the vehicle approach determination unit 17 when the communication unit 14 receives vehicle position information from the in-vehicle device 2 and the vehicle approach determination unit 17 determines that an approach notification should be issued in response to the vehicle position information. The approach notification history information 115 is used when the vehicle approach determination unit 17 performs a process of determining whether or not to notify the worker terminal 4 of approach.

FIG. 8 shows an example of the approach notification history information 115. The approach notification history information 115 shown in FIG. 8 includes "Vehicle" indicating the name of the transportation vehicle, "Base" indicating the name of the base to which the transportation vehicle is heading, and "Department" indicating the name of the delivery area of the transportation destination. , "Date" and "Time" indicating the date and time when the transportation management device 1 acquired the vehicle location information indicating the latitude and longitude of the current location of the vehicle from the on-vehicle device 2, and "Latitude" indicating the latitude of the acquired transportation vehicle. , items such as "longitude" indicating the acquired longitude of the transport vehicle, "notification flag" indicating whether or not an approach notification was sent, and whether response information was received from the worker terminal 4 in response to the approach notification. has. When the vehicle approach determination unit 17 determines to notify an approach notification and the communication unit 14 transmits the approach notification data to the worker terminal 4, 1 is recorded in the “notification flag”. Further, when the communication unit 14 receives response information from the worker terminal 4 that received the approach notification, 2 is recorded in the "notification flag". The "notification flag" item is not limited to numbers, and may be any information that can identify whether approach notification data has been transmitted or not, and whether response information from the worker terminal 4 has been received.

In the example of Figure 8, as of 15:04 on May 10, 2019 on the second line, car No. 1 has not approached the c delivery area of factory A and has not been notified, but on the third line At the time of 15:05, it has reached a point with a latitude of 34.967258 and a longitude of 138.42169, and the distance has become less than the threshold, indicating that the notification has been received.

The vehicle transport destination information 116 shown in FIG. 3 is information indicating the base and delivery area to which the transport vehicle will transport the product next. The vehicle transport destination information 116 is generated when the next delivery area specifying unit 16 identifies the base and its delivery area as the next destination of the transport vehicle through the next delivery area identification process described later, and is generated according to the progress of transportation. Updated.

FIG. 9 shows an example of the vehicle transport destination information 116. The vehicle transport destination information 116 shown in FIG. 9 includes "vehicle" indicating the name of the transport vehicle, "base" indicating the name of the base to which the transport vehicle is heading, and "distribution area" indicating the name of the transport destination. It has the following items. The items "vehicle", "base", and "delivery area" are not limited to names, and may be any information that identifies them. In the example of FIG. 9, at the moment, car No. 1 is being transported to delivery area c of factory A, car No. 2 is being transported to delivery area a of factory F, and so on. ．． ．． It shows that.

The next delivery area identification unit 16 shown in FIG. 3 performs a process of identifying the next delivery area to which the transport vehicle will go based on the operation plan information 111 stored in the transportation related storage unit 15. Further, the next delivery area identification unit 16 uses cargo information 112 transmitted from the shipping base terminal 3, loading and unloading order information 113 stored in advance in the transport-related storage unit 15, and transport destination change transmitted from the on-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 the next delivery area identification unit 16 determines that there has been a change in the operation plan, it performs a process of changing the delivery area of the next transportation destination. Here, cases where there is a change in the operation plan include cases where products are no longer transported to a planned delivery area, products are transported to an unplanned delivery area, road conditions, weather conditions, etc. This refers to cases where the driver changes the transportation route due to reasons such as:

The next delivery area identifying unit 16 selects, from the information recorded in the operation plan information 111, a base and its delivery area where the product transportation has not been completed and has the earliest expected arrival time as the next transportation destination. I judge that.

Further, the next delivery area identification unit 16 derives the base and its delivery area to which the transport vehicle will go next from the cargo information 112 and the loading/unloading order information 113, and the base and delivery area identified from the operation plan information 111. By comparing with the ward, it will be determined whether the transportation plan needs to be changed or not. The next delivery area identification unit 16 reads information on the loading order and unloading order of the corresponding transportation vehicle from the loading and unloading order information 113, and the "loading order" is "before" and the "unloading order" is " Information on whether the loading order is "later" and the "unloading order" is "front" is obtained.

When the “loading order” is “before” and the “unloading order” is “after”, the next delivery area identification unit 16 determines the base and delivery area of the product with the slowest loading time from the cargo information 112. It is determined that the destination is When the “loading order” is “later” and the “unloading order” is “front,” the next delivery area identification unit 16 determines the base and delivery area of the product with the earliest loading time from the cargo information 112. It is determined that the destination is In the example of transport vehicle No. 1 with the loading information 112 shown in FIG. 5 and the loading/unloading order information 113 shown in FIG. Since "order" is "later", the next delivery area identification unit 16 determines that delivery area c of factory A, which is the destination of the part 7 with the slowest loading time, is the next destination from the cargo information 112. It is derived that there is.

Next, the next delivery area identification unit 16 compares the delivery area of the base identified from the operation plan information 111 with the delivery area of the base derived from the cargo information 112 and the loading/unloading order information 113, and Determine whether there has been a change in plans. If the respective delivery areas are the same, the next delivery area identification unit 16 determines that there is no change in the operation plan, and, according to the operation plan information 111, identifies the base with the earliest scheduled arrival time in the operation plan information 111 and its delivery area. It is determined that it is the next destination. If the respective delivery areas are different, the next delivery area identification unit 16 determines that there has been a change in the operation plan and selects the delivery area of the base derived from the cargo information 112 and the loading/unloading order information 113 for the next transportation. It is determined that it is the first.

Further, upon receiving the transport destination change information from the on-vehicle device 2, the next delivery area identification unit 16 determines that there has been a change in the operation plan, and selects the base and delivery area indicated by the transport destination change information as the next transport destination. I judge that.

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

When the next delivery area for the transportation vehicle is identified by the next delivery area identification unit 16 and the vehicle approach determination unit 17 receives a notification thereof, the vehicle approach determination unit 17 determines the position of the next delivery area specified by the next delivery area identification unit 16 from the delivery area information 114. Get information and distance thresholds. The vehicle approach determination unit 17 calculates the distance between the vehicle and the delivery area based on the latitude and longitude included in the vehicle position information received from the on-vehicle device 2 and the latitude and longitude of the delivery area. The vehicle approach determination unit 17 compares the calculated distance with a threshold value, and when determining that the calculated distance is less than the threshold value of the delivery area information 114, generates approach notification data.

The vehicle approach determination unit 17 acquires the worker terminal ID of the corresponding delivery area from the delivery area 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 area specified by the next delivery area identification unit 16.

When transmitting approach notification data, if the "transmission type" of the delivery area information 114 is all at once, the data will be transmitted to all registered worker terminals 4, and if the "transmission type" has priority, the data will be sent to all registered worker terminals 4. The data is sent to the higher worker terminal 4. In the example of the delivery area information 114 shown in FIG. 7, when approach notification data is sent to the worker terminal 4 of delivery area a of base A, the "transmission type" has priority, so the worker with the highest priority The message will be sent to the terminal with terminal ID 7. The format of the notification is, for example, email, SMS notification, push notification, etc.

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

Next, the functional configuration of the in-vehicle device 2 shown in FIG. 1 will be described with reference to FIG. 3. The on-vehicle device 2 includes a measurement unit 20 that measures the latitude and longitude of the current location of the transportation vehicle, and an input unit 21 that receives input from the driver to change the next delivery area and input information indicating that transportation has been completed. , a communication unit 22 that transmits the latitude and longitude information measured by the measurement unit 20 and a notification of a change in delivery area to the transport management device 1, a storage unit 23 that stores information, and a display unit 24 that displays the information received by the communication unit 22. and a control unit 25 that controls the operation of the in-vehicle device 2.

The measurement unit 20 measures the latitude and longitude of the current location at regular intervals. For example, there are 1Hz positioning that measures once per second, and 10Hz positioning that measures 10 times per second. The control unit 25 adds information on the measured date and time to the information on the measured latitude and longitude, 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 receives an input of a change of destination of transportation by the driver of the transportation vehicle and an input of information indicating that transportation has been completed. The input unit 21 is used when the driver determines that the vehicle will be transported to a destination different from that in the operation plan information 111 due to road conditions, weather, etc., for example. The driver inputs a new base and delivery area to the input unit 21 from the list of bases and delivery areas displayed on the display unit 24. The input method may be any method, such as selecting from a pull-down list of bases and delivery areas displayed on the display unit 24, selecting using radio buttons, or inputting numbers corresponding to bases and the list. do not have. The control unit 25 generates transport destination change information including information on the new base and delivery area input by the driver, and information on the input date and time, and transmits it to the communication unit 22. When the communication unit 22 receives the transport destination change information, it transmits it to the transport management device 1 via the network 5.

Obtain information on bases, districts, etc. The cargo information generation section 34 generates cargo information from the information acquired by the acquisition section 30 and the date and time of reading, and stores it in the storage section 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 explained with reference to FIG. 3. The worker terminal 4 is used by a worker who unloads products at the delivery area of the base. The worker terminal 4 includes a communication unit 40 that receives an approach notification from the transport management device 1 and transmits response information thereto, and an input unit 41 that receives response information input by a worker in response to the received approach notification. , a display unit 42 that displays information on approach notifications, a storage unit 43 that stores information received by the communication unit 40, and a worker terminal 4 that includes the communication unit 40, the input unit 41, the display unit 42, and the storage unit 43.

The worker is sent information that informs the driver that the worker is ready to perform the unloading work, such as YES/NO, possible/impossible, etc. displayed on the display unit 42, for example.

Next, the operation of the transportation management system 100 will be explained. The main operation of the transportation management system 100 is that the transportation management device 1 identifies the next delivery area for each transportation vehicle, and when the distance to the delivery area satisfies a criterion, it approaches the worker's terminal. This is an action to notify.
First, the next delivery area identification process in which the transport management device 1 identifies the next delivery area to which each transport vehicle will move will be described with reference to FIG.

After the product is loaded onto the transport vehicle at the shipping base and the next delivery area identification unit 16 receives the cargo information 112 from the shipping base terminal 3 or receives a notification of the completion of transportation from the on-vehicle device 2, the next delivery area identification unit 16 performs the process shown in FIG. The process of identifying the next delivery area to which the indicated transport vehicle is headed is started.

First, the next delivery area identification unit 16 acquires the operation plan information 111 from the transportation-related storage unit 15 (step S11), and selects from among the bases and delivery areas in which the product transportation has not been completed in the operation plan information 111. , the base and delivery area with the earliest scheduled arrival time are identified as the next transportation destination (step S12), and stored in the vehicle transportation destination information 116 (step S13).

Next, the next delivery area identification 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 cargo information 112 and the loading/unloading order information 113. , performs processing to derive the base and delivery area that will be the next transportation destination. The loading/unloading order information 113 includes whether the "loading order" of the corresponding transport vehicle is "front" and the "unloading order" is "back", or the "loading order" is "back" and "unloading". Either "order" is "previous" or "previous" is stored. If the "loading order" of the acquired loading and unloading order information 113 is "before" and the "unloading order" is "after" (step S15; YES), the next delivery area identification unit 16 determines the loading information. 112, the base and delivery area of the product with the slowest loading time are derived as the next transportation destination (step S16).

If the "loading order" of the acquired loading and unloading order information 113 is "later" and the "unloading order" is "front" (step S15; NO), the next delivery area identification unit 16 determines the loading information 112, the base and delivery area of the product with the quickest loading time is derived as the next transportation destination (step S17).

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

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

Thereafter, if there is no notification of a change in transportation destination from the on-vehicle device 2 (step S21; NO), the next delivery area identification unit 16 ends the process. When the next delivery area identification unit 16 receives a notification of a change in transportation destination from the on-vehicle device 2 (step S21; YES), it determines that the base and delivery area included in the notification of a change in transportation destination are the next delivery area ( Step S22), the vehicle transportation destination information 116 is corrected (step S23), and the process ends.

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

Next, FIG. 11, which shows the flow of the vehicle approach judgment process, will be described with respect to the process by the vehicle approach judgment unit 17 to judge that the transport vehicle has approached the delivery area and to send an approach notification to the worker terminal 4. Refer to and explain.

When the next delivery area identification unit 16 specifies the next delivery area to which the transport vehicle is heading, it notifies the vehicle approach determination unit 17 of this fact. When the vehicle approach judgment unit 17 receives the notification from the next delivery area identification unit 16, it starts the vehicle approach judgment process shown in FIG. (Step S31).

When the vehicle approach determination unit 17 receives vehicle position information indicating the current position of the transport vehicle from the on-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 was acquired in a transport-related memory. The information is stored in the approach notification history information 115 of the unit 15 (step S33). Thereafter, 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 area recorded in the delivery area information 114 (step S34). Thereafter, the vehicle approach determination unit 17 reads the threshold value from the delivery area information 114, and determines whether the calculated distance is less than the threshold value (step S35).

If the vehicle approach determination unit 17 determines that the calculated distance is equal to or greater than the threshold (step S35; NO), it does not perform any processing until the next vehicle position information is received. If the vehicle approach determination unit 17 determines that the calculated distance is less than the threshold (step S35; YES), it acquires the worker terminal ID and transmission type information of the designated delivery area from the delivery area 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 to the worker terminal 4 of the acquired worker terminal ID, and stores the time of transmission (step S37). When the transmission of the approach notification data is defined as "all at once" in the transmission item of the delivery area information 114, the approach notification data is sent to all worker terminals 4 registered in the delivery area information 114, and is set to "priority". If it is defined, the approach notification data is transmitted to the worker terminal 4 having a higher priority of "worker terminal". When the vehicle approach determination unit 17 transmits the approach notification data, it 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).

After transmitting the approach notification data, the vehicle approach determination unit 17 receives 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 stores “2” indicating that the response information from the worker terminal 4 has been received in the transportation-related storage unit 15. It is stored in the approach notification history information 115 (step S42), and the vehicle approach determination process is ended. On the other hand, if the vehicle approach determination unit 17 does not receive response information to the transmitted approach notification (step S40; NO), the retransmission interval of the delivery area information 114 has elapsed from the time when the approach notification data was transmitted. (Step S41; NO), response information is accepted.

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

As explained 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 section 15, the cargo information 112 transmitted from the worker terminal 4, and the on-vehicle device 2. The next delivery area for the transport vehicle is determined based on the transport destination change information sent from the system. In addition, the transportation management device 1 calculates a distance from the vehicle position information received from the in-vehicle device 2 and the location information of the delivery area information 114, and registers it in the delivery area information 114 by comparing the calculated distance with the distance threshold. It is determined whether or not to notify the worker terminal 4 of the approach. In this way, the transport management device 1 allows workers at the delivery area where the transport vehicle transports between bases with multiple delivery areas to proceed, by flexibly responding to changes in the transport plan at the last minute. You can be notified of the arrival in advance.

[Modified example]
The present invention is not limited to the above embodiments, and various modifications and applications are possible. In the above specific example, the vehicle approach determination unit calculates the distance from the latitude and longitude received from the in-vehicle device 2 and the latitude and longitude of the delivery area set in the delivery area information 114, and if the calculated distance is less than the threshold, , although it has been explained that an approach notification is notified, the present invention is not limited to this, and the latitude and longitude of the transportation vehicle can be set by setting the maximum latitude, minimum latitude, maximum longitude, and minimum latitude of the delivery area in the delivery area information 114. If the vehicle is within the specified range, a notification of the approach may be given.

Furthermore, although it is assumed that the transportation-related storage unit 15 stores the operation plan information 111 in advance, the operation plan information 111 may not be stored therein. The next delivery area specifying unit 16 may determine the base and delivery area specified from the cargo information 112 and the loading/unloading order information 113 as the next transport destination, and store it in the vehicle transport destination information 116.

In the embodiment described above, the distance threshold is set as a criterion for notifying the approach notification, but the threshold may be set for the time until arrival. The time it takes to arrive is basically calculated by dividing distance by speed. Further, for example, by linking with a navigation system, setting the next destination as the destination, and obtaining the estimated time of arrival from the navigation system, the time until arrival in consideration of road conditions etc. may be calculated.
Furthermore, the distance is not limited to a straight line distance, but may be an actual travel distance based on map information.
Moreover, the approach notification may be transmitted not only when distance or time but also when other predetermined conditions are met.

In the above embodiment, when the interval between delivery areas is short, or when unloading work at the delivery area does not require much time, the time from receiving the notification until the transport vehicle arrives becomes extremely short. There are cases where this happens. In order to avoid such an event, for example, in step S13, up to n (n is a natural number of 2 or more) destinations are specified and stored in the vehicle transportation destination information 116, and in step S19, up to n destinations are specified and stored in the vehicle destination information 116. Determine whether there is a change in the transportation destination, update the vehicle transportation destination information 116 as necessary in step S20, calculate the expected time to n destinations in step S35, and if it is less than the threshold, , may be notified in step S37. In addition, for the second and subsequent delivery areas, the unloading time at the previous delivery area is taken into consideration in the estimated time.

Although a product is exemplified as an object to be transported, the type of cargo, packaging style, etc. may be arbitrary, such as parts, materials, agricultural products, marine products, delivery products, etc.

Further, in the above embodiment, for example, the program executed by the CPU of the control unit 10 of the transportation management device 1 was stored in the storage unit 11 in advance. However, the present invention is not limited thereto, and the above program can be stored in a computer readable recording medium (CD-ROM (Compact Disc Read-Only Memory), DVD (Digital Versatile Disc), MO (Magneto), for example. In addition to being able to be applied by storing the program on a storage device (such as an optical disc), the program can also be applied by storing the program in a storage on the Internet and downloading it.

In addition, when the functions of the transport management device 1 are executed by sharing between an OS (Operating System) and an application program, or by cooperation between the OS and an application program, only the application program is stored in a recording medium, storage, etc. It's okay. It is also possible to superimpose a program on a carrier wave and distribute it via a network. Then, the above-described process may be designed to be executed by starting this program and executing it under the control of the OS in the same way as other application programs.

Furthermore, the present invention is not limited to the embodiments described above, and can be implemented in other forms by making appropriate changes.
