Further the management processing section 22, from the detected current position, or when an employee moves to the access point AP _I is not installed the access point AP _I from a region that is located area, wireless device NP _J Is determined to move out of the management area where the current position can be managed, and when it is predicted to move out of the management area, a message instructing a destination input is output via the digital processing unit 21.

When an instruction to display management information is issued from any terminal T, the wireless device ID codes of the wireless devices NP _{1 to} NP _X owned by the designated employee are preset and stored. It is specified based on correspondence information indicating the correspondence between the employee name and the wireless device ID code of the wireless device held by the employee. Then, management information corresponding to the specified wireless device ID code, that is, information such as the current position, the destination information, whether the mobile device is moving, and the required time is read. And a place name representing the current location,
If necessary, a place name indicating the destination, whether or not the user is moving, and the required time are output to the terminal T.

The terminal T is connected to the destination management device CU via the communication line 2, and an operator operates an input device (not shown) to request display of destination management information.
When the desired employee name is input, a request for displaying the destination management information of the employee name is made to the destination management device CU via the communication line 2, and the destination management device CU sends the current position corresponding to the employee name. , Destination information, whether or not the user is moving, and required time. Then, the employee name and the location name of the current position are displayed in association with each other, and when the destination information is notified, the notified destination location name is displayed. At this time, when the user is moving, the destination place name is displayed in a moving mode in which the moving destination is displayed in a display form capable of clearly indicating that the user is moving. For example, the destination name blinks or moves together with the destination name. For example, the character "middle" is displayed. At the same time, the required time is displayed.

Next, the operation of the above embodiment will be described with reference to a flowchart of FIG. 5 showing an example of a destination management process executed by the management processing section 22 of the destination management device CU. In the management processing unit 22, any of the access points A
From P _I, when it is notified that there is a new wireless device NP ₁ ~NP _X participating in the network, the step S
11 to step S12, the wireless device NP specified by the wireless device ID code for which the participation notification has been made.
The current location of the access point AP that sent this notification
Is updated to the place name specified by the ID code.

Next, the process proceeds to step S13, where it is determined whether or not the administrator is going to move outside the management area, that is, outside the area where the access point AP is located and the position of the administrator can be detected by this. judge. This determination is made, for example, when moving from an area where the access point AP is installed to an area where the access point AP is not installed. That is, when the access point AP is installed only inside the company room, the entrance of the company building or this The access point AP closest to the entrance is the outermost access point AP in the management area, and the outdoor side beyond the communicable range of this access point AP is outside the management area. Therefore, the current position of the wireless device NP _{J is} the position of the access point AP closest to the entrance or exit of the company building, and at the time before moving to the current position, for example, the position inside the access point AP in the management area. If it is located near the access point AP such as a passage toward an entrance, it can be considered that the managed person is going to move out of the management area.

When it is determined that the administrator is going to move out of the management area in this way, the flow shifts to step S14, and it is determined whether or not a destination input to move out of the management area has been made. In this determination, for example, it is determined whether or not a place outside the management area is notified as destination information. If the destination information outside the management area is not notified, or if the destination notification is performed but the place is not outside the management area, step S
Moves to 15, the message data for a destination input request the digital processing unit 21 outputs, to manage the wireless device ID code of the wireless device NP _J as moving. Then, control goes to a step S21.

On the other hand, when the ID of the wireless device that has newly joined the network is not notified in step S11, when the movement outside the management area is not detected in step S13, and when the movement outside the management area is detected in step S14, If the destination notification is made, the process directly proceeds to step S21.

In this step S21, the wireless device N
Judge whether the destination information was input from P _J ,
When the destination information is input, the process proceeds to step S22, and after updating the destination information based on the input destination information and the corresponding wireless device ID code, the process proceeds to step S23.

In this step S23, it is determined whether or not the inputted destination information is located outside the management area. If the inputted destination information is outside the management area, the flow shifts to step S24, where the location information of the destination notification position stored in advance and The distance between them is calculated from the position information of the current position, and the time required to reach the destination notification position is calculated based on the calculated distance and the average walking speed of the employee. Then, the arrival time is predicted from the required time and the current time, and is managed in association with the wireless device ID code.

On the other hand, when it is determined in step S23 that the area is within the management area, the movement status monitoring processing shown in FIG. 6 is started. Then, the process returns to step S11.

If the destination information is not input in step S21, the process returns to step S11.

[0047] The moving status monitoring process determines, for example, as shown in FIG. 6, first, in step S51, whether the destination notified position notified by the current location and the wireless device NP _J match.

When it is determined that they do not match, the process proceeds to step S52, where the current position and the destination display position do not match, and it can be considered that the mobile device is moving. to manage. Next, the process proceeds to step S53, where the time required to reach the destination notification position from the current position is predicted from the positional relationship between the current position and the destination notification position, and is managed in association with the wireless device ID code. The required time is, for example, the current position, that is, the access point A
The installation location of P is detected in advance, and the location of the destination notification position, for example, the location of the access point AP if the access point AP is installed, or the location where the access point AP is not installed. If there is, the position information is detected in advance, the position information corresponding to the detected current position and the notified destination is searched and the distance between them is calculated, and the calculated distance and the average walking speed of the employee are calculated. Is calculated based on The present invention is not limited to this. For example, for each access point AP, the distance between each access point AP and each destination based on the access point AP may be calculated and stored as a table representing the distance for each destination. .

Next, the flow shifts to step S54, where the wireless device NP which has sent the destination in step S21 has been notified.
It is determined whether or not the current position has been updated. When the current position has been updated, the process returns to step S51.

When the current position and the destination notification position match, the process proceeds from step S51 to step S58, where the employee determines that the destination notification position has been reached, and
The management of the wireless device ID code as moving is stopped. Then, the movement status monitoring process ends.

Here, the processing in step S12 in FIG. 5 corresponds to the position recognition means, the processing in step S24 in FIG. 5 and the processing in step S54 in FIG. 6 correspond to the required time prediction means, and the processing in step S14 in FIG. Corresponds to the out-of-management-area movement detecting means, and the processing in step S51 in FIG. 6 corresponds to the moving detecting means.

[0052] Therefore, now, enters the building employees M is, and in this doorway is assumed that the access point, for example, AP ₁ is installed, reaches to communicate a position capable of wireless device NP _M is the access point AP ₁ At that point,
Communicating with the wireless device NP _M and the access point AP ₁ is started, the access point AP _1, recognizes the wireless device NP _M, new self access point ID code and a communication from the wireless device NP _M has joined the network adding a wireless device ID code of the wireless device NP _M is previously performed to join notification to the network of the wireless device NP _M against the destination management unit CU by.

[0053] In the destination management unit CU, steps S11 since the join notification is performed and proceeds to step S12, the current position corresponding to the notified wireless device ID code to the access point location name specified by the AP ₁ Update. Then, since the vehicle has entered the company room and has not moved out of the management area, the process proceeds from step S13 to step S2.
Move to 1. If the destination information is not input, the process returns to step S11.

Then, as the employee M moves inside the office,
Access point AP₁ Move out of range
And the access point AP at this point₁ Lost communication with
The next access point, eg AP_Two And wireless devices
NP_M Communication between the employee and
APs are sequentially switched as they move
Will be. Therefore, at each access point AP,

From, with your own access point ID code,
A certain wireless device NP_M Wireless device ID code,
Wireless device NP _M Report that they have joined the network
The information to be notified is transmitted to the destination management device CU.

For this reason, the destination management apparatus CU proceeds from step S11 to step S12, updates the current position information, and proceeds to step S13. However, since the movement is within the management area, the processing proceeds from step S13 to step S13. S
Move to 21. Then, if done input destination information, step S11, S12, S13, will be repeated the processing of S21, each time the join notification is made, the current position corresponding to the wireless device NP _M is accessed location name that corresponds to the point AP _1, the location name corresponding to the AP _2, will be updated in the order and so on ....

[0056] Thus, the current position to be managed by the destination management unit CU, the location name that corresponds to an access point AP _1, the location name corresponding to the AP _2, because is updated and so on ..., by operating the terminal T when you do the destination of the display instruction of employees M, for example, when the wireless device NP _M has been recognized by the access point AP _1, the current position becomes a place name that corresponds to an access point AP _1, for example, "the entrance to the building." Will be displayed as Each time the current position is updated, the access point AP
_The location name corresponding to ₂ and the location name corresponding to the access point AP ₃ are updated.

From this state, the employee M can, for example, contact another department.
To move, the wireless device NP _M To turn on the audio

You.

In the destination management unit CU, the digital processing unit 2
In step 1, voice recognition is performed after expanding the received voice data. Then, the destination information as a result of the voice recognition is notified to the management processing unit 22.

When the destination information is notified, the management processing section 22 proceeds from step S21 to step S22,
The process proceeds to step S23 after updating the destination that has been notified of the destination information of the wireless device ID code corresponding to the wireless device NP _M. At this time, the destination is "Department A"
Since it is within the management area, the process shifts from step S23 to step S25 to start the movement status monitoring process.

[0060] Then, it is determined whether or not the current position of the wireless device NP _M that has registered as the destination information and the current position information match, in this case not yet moved to the department A, because they do not match goes from step S51 to step S52, the wireless device ID code of the wireless device NP _M and moving manages, further, from the position information of the current position and the destination notification position, based on the distance between them, "department a The required time required to reach "" is estimated, and the required time is managed, for example, "5 minutes", or the required time is added to the current time and managed by the arrival time (step S53).

[0061] Thus, in the terminal T, to display the location name that corresponds to, for example, the access point AP ₁₀ as the current position, "Department A" is displayed as the destination of employees M, this time, the "Department A" movement Since the message is displayed in the middle mode, for example, blinking or is displayed together with the character “moving”, the operator of the terminal T can easily recognize that the employee M is currently moving toward “department A”. It is also possible to recognize the required time or the arrival time. At this time, the current position is also displayed,
You can recognize where you are moving now.

[0062] Then, with the employees M moves, moving outside the communication range of the access point AP _10, the communication with the access point AP ₁₀ at this time is cut next access point AP _I and wireless device NP the communication is started between the _M, the access point AP sequentially cut switched as hereinafter employees M is moved. When the employee M reaches the destination notification position in this case, "department A", since the process proceeds from step S51 to step S58, the the management processor 22, not a moving wireless device ID code of the wireless device NP _M Manage as

Therefore, the terminal T ends the display of the destination name of the employee M in the moving mode. As a result, the destination name of the employee M is not displayed blinking or the like, so that the operator can recognize that the employee M has arrived at the destination notification position.

On the other hand, when the employee M moves from the indoor to the entrance to go out of the office, the access points AP are sequentially switched in accordance with the movement. Then, step S1
1, S12, S13, and S21 are repeatedly performed, and the current position of the employee M managed by the management processing unit 22 is also sequentially updated. Then, the access point AP of the communication partner of the wireless device NP _M is, when switched from the access point AP ₂ is located in one front of the said access point AP ₁ installed in the doorway to the access point AP _1,
The access point AP ₁ is an access point AP which is located outermost in the management area, since it has moved from the access point AP ₂ in the direction of the AP _1, it is predicted to move to the management area outside. Therefore, step S
Then, control goes from step 13 to step S14.

[0065] At this time, the employee M is if doing a destination notification, the process proceeds from step S14 to step S15, in order to carry out the destination request, to send the message data to the access point addressed to AP _1.

Thus, in the digital processing unit 21,
It generates audio digital signal corresponding to the message data for a destination input request, which via the communication line 2, and transmits to the access point addressed AP _1.

[0067] transmitted via a short-range wireless communication interface 11 so the access point AP ₁ receives this, the wireless device NP _M has received this, from the speaker 3 to the voice synthesizing it in the digital processing unit 5 To utter.

Therefore, the employee M can recognize that the destination is not input. And employee M
But, for example, a factory or the like in the same site, when speech input a building outside the destination, which is input to the destination management unit CU via the access point AP _1, the process proceeds to step S23 through step S22 from step S21, the radio device destination information NP _M is updated, since this time is outside the management area, the process proceeds from step S23 to step S24, and the calculated arrival time based on this calculated time required until notified destination, radio It is managed in association with the wireless device ID code of the device NP _M.

As described above, the employee can input the destination by voice, and the input destination information is notified to the destination management unit CU via the access point AP. There is no need to bother to go to a location and do something to describe the destination.
