[Terminal location management server]
The terminal position management server 15 is a server that manages the positions of the in-vehicle terminal 11 and the portable terminal 12.
Further, the terminal location management server 15 acquires location information of all the terminals 11 and 12 specified by a terminal location specifying unit (not shown).
In the terminal position specifying means of this embodiment, specifically, all the terminals 11 and 12 receive GPS signals from GPS (Global Positioning System) artificial satellites, and the terminal position management server based on the GPS signals, The position information of all the terminals 11 and 12 is obtained as coordinate data (latitude, longitude, altitude as absolute position information).
For this reason, the terminal position management server 15 can grasp the distance between the terminals 11 and 12. For example, the linear distance between the in-vehicle terminal 11 and the portable terminal 12 of the forklift L or the separation distance on the movement route R Can be grasped.

Next, the movement management method of the forklift L1 by the movement management system according to this embodiment will be described.
In the warehouse shown in FIG. 1, a plurality of forklifts L1, L2 and workers M1 to M8 exist, and a passage where the worker M exists and a passage where the worker M does not exist are mixed.
In FIG. 1, there are two forklifts L1 and L2. For convenience of explanation, the in-vehicle terminal 11 of one forklift L1 is used as a reference, and the in-vehicle terminal 11 of the other forklift L2 is carried by an operator M. Similar to the portable terminal 12, it is handled as another terminal.
Furthermore, it is assumed that the forklift L1 needs to move to the shelf (S5-10) of the designated storage shelf S5 based on the entry or exit instruction.
In this case, the movement path R from the current position of the forklift L1 to the designated movement destination includes movement paths R1 to R5, and these movement paths R1 to R5 include at least one work area E. It is a form that passes through.

First, the terminal location management server 15 collects location information of all the terminals 11 and 12.
Next, the article management server 14 develops the positions of all the terminals 11 and 12 on the map information based on the position information of all the terminals 11 and 12.
As a result, the number of other forklifts L2 and workers M existing or close to each of the movement paths R1 to R5 is grasped (see STEP 1 in FIG. 3).
Here, based on the number of terminals 11 and 12 for each work area E in the movement route R, the number of terminals 11 and 12 existing in each of the movement routes R1 to R5 is grasped.
Next, the article management server 14 selects the shortest distance travel route R from the travel routes R having the smallest number of terminals 11 and 12 (see STEP 2 in FIG. 3).

In the situation shown in FIG. 1, the movement route R3 is a movement route R that sequentially passes through the work areas E9, E10, E11, E4, and E8, and the workers M4 and M5 exist in the work area E4. Workers M4 and M5 are present or close to R3.
On the other hand, the movement route R4 is a movement route R that sequentially passes through the work areas E9, E10, E11, E5, and E8, and another forklift L2 and a worker M6 exist in the work area E5. The forklift L2 and the worker M6 exist or are close to R4.
In this case, the number of the other terminals 11 and 12 on the movement route R3 and the movement route R4 is the smallest, and these movement routes R3 and R4 are used when the designated forklift L1 moves, It can be said that this is a travel route R with a small number of passes by M.
Therefore, the article management server 14 selects the travel route R3 having a short distance to the travel destination among these travel routes R3 and R4 as the optimum travel route R.

Next, the article management server 14 transmits the optimal travel route R3 and the position information of all the terminals 11 and 12 from the access point 13 to the in-vehicle terminal 11 in the forklift L1 via the wireless LAN 17 (see STEP 3 in FIG. 3). ).
The in-vehicle terminal 11 displays all the positions of the selected optimal travel route R3 and other terminals 11 and 12 as a map.
By displaying the optimal travel route R3 on the in-vehicle terminal 11 as a map, the driver of the forklift L1 can recognize the travel route R3 to be moved.
Moreover, the driver | operator of the forklift L1 can recognize the position of another forklift L2, and the position of the workers M1-M8 because all the positions of the other terminals 11 and 12 are displayed on the map.

The article management server 14 transmits the optimal travel route R3 and the position information of all the terminals 11 and 12 from the access point 13 to the in-vehicle terminal 11 in the forklift L1 via the wireless LAN, while existing or close to the optimal travel route R3. Information indicating that the forklift L1 is scheduled to approach is transmitted from the access point 13 to the terminals 11 and 12 via the wireless LAN 17.
As a result, the driver of another forklift L2 recognizes that the forklift L1 is scheduled to pass the movement route R3 through the in-vehicle terminal 11 and the workers M1 to M8 through the portable terminal 12.

Next, the article management server 14 determines whether or not there is another terminal 11 or 12 on the selected optimum movement route R3, and if another terminal 11 or 12 exists, the optimum movement route R3. In FIG. 3, the in-vehicle terminal 11 announces that there are other terminals 11 and 12 (see STEP 4 in FIG. 3).
Specifically, the corresponding forklift L2 and the worker M are highlighted on the display unit of the in-vehicle terminal 11, or a warning sound for notifying the presence of the other forklift L2 and the workers M4 and M5 is output.
In the case of FIG. 1, since another forklift L2 is not present or close to the movement route R3, only the workers M4 and M5 are subject to the notification expression.
As a result, the driver of the forklift L1 can recognize the presence of workers M4 and M5 that are likely to pass each other on the movement route R3 to be moved.

Next, the article management server 14 issues a warning at the in-vehicle terminal 11 of the forklift L1 (see STEP 5 in FIG. 3), and forks the workers M4 and M5 carrying terminals 12 on the optimum travel route R3. An instruction is given to issue a warning notifying that L1 is approaching (see STEP 6 in FIG. 3).
At the portable terminal 12 carried by the workers M4 and M5, a warning sound is given.
As a result, the workers M4 and M5 who carry the portable terminal 12 that is present or close to the optimal travel route R3 recognize that they are present or close to the travel route R3 of the forklift L1.

If there is no other forklift L2 or worker M on the optimal travel route R3, the article management server 14 issues a warning to the in-vehicle terminal of the forklift L1 and does not give an instruction.
Accordingly, the driver of the forklift L1 can recognize that there is no other forklift L2 or the operator M on the optimum movement route R3 by not giving a warning after the optimum movement route R3 is displayed.
In addition, when the number of the other terminals 11 and 12 is the same and the movement distance to the destination is the same distance, there are a plurality of optimum movement routes R. May be selected.

The mobility management system and mobility management method according to this embodiment have the following effects.
(1) Since all the other terminals 11 and 12 in the movement route are taken into consideration and the optimum movement route R for the forklift L1 is selected from the plurality of movement routes R, for example, the movement time of the forklift L1 is reduced. Increase the likelihood of being
(2) After selecting the travel route R that is optimal for the movement of the forklift L1, the positions of all the other terminals 11, 12 are displayed on the in-vehicle terminal 11, so that the driver of the forklift L1 The route R can be specifically recognized, and the positions of all the other terminals 11 and 12 can be grasped.

(3) When another terminal 11, 12 is present or close to the selected moving route R, the forklift L1 moves along the selected moving route R, and the forklift L1 and another terminal 11, 12 approach each other. The terminal 11 and the other terminals 11 and 12 warn that the forklift L1 and the other terminals 11 and 12 are approaching each other. Accordingly, the driver of the forklift L1 is recognized to approach the other terminals 11 and 12, while the driver of the other forklift L2 having each of the other terminals 11 and 12 and the operator M can approach the forklift L1. Can be recognized.
(4) Of the travel routes R having the smallest number of other terminals 11 and 12 that are present or close to the travel route R leading to a specific destination, the travel route R having the shortest travel distance is optimal for the forklift L1. Since the travel route R is selected, the travel time of the forklift L1 that travels along the optimal travel route R is different regardless of whether the forklift L1 is in the optimal travel route R or not with another terminal 11, 12. This is shorter than the travel time for moving the travel route R.
