The display condition input part 2201 of application server 110 is accepted the appointment (step 2701) of the display condition relevant with the user that will show there from the viewer.As display condition, for example specify user's name, user ID, department name or floor name.When specifying user's name or user ID, also can be the structure that to specify a plurality of user's names or user ID.In addition, when the viewer specifies user's name or user ID, also can be the structure that the viewer can also refer to the floor name at settled preceding place.At this moment, when the result person of being to use of retrieve position with the viewer during at different floors, be not shown as and exist, perhaps do not show the result of retrieve position.
Below, the operation of making the application server 110 under the situation of the indication that shows user's name " Tanaka is the youth too " the viewer at first is described.
Display condition input part 2201 is notified to user's information treatment part 2202 with the display condition of viewer's appointment, and user's information treatment part 2202 confirms whether specified display condition is user's name or user ID (step 2702).
As the result who confirms during for the specified display condition person of being to use name or user ID ("Yes" of step 2702), judge whether the user of display condition appointment is a plurality of (steps 2703).
When judging ("Yes" of step 2703) when having only a user designated, user's name or user ID are notified to user's Information Management Department 2203.On the other hand, when the user who judges the display condition appointment has ("No" of step 2703) when a plurality of, from a plurality of user's names that are designated as display condition or user ID, select untreated user's name or user ID (step 2704), and user's name or the user ID that selects is notified to user's Information Management Department 2203.Here, user's name " Tanaka is the youth too " is notified to user's Information Management Department 2203.
Receive user's Information Management Department 2203 retrievals and the user's name notified or the corresponding use end message (step 2705) of user ID of the notice of user's name or user ID, and return to user's information treatment part 2202 as replying.In the example of Figure 23, the use terminal that retrieves user's name " Tanaka is the youth too " is " tanaka_pc ", thereby this information just becomes and returns to replying of user's information treatment part 2202.On the other hand, when the result person of the being to use Information Management Department 2203 of retrieval does not have to preserve the use end message corresponding with the user's name notified or user ID, reply necessary fault processing (step 2716) such as mistake.
When user's information treatment part 2202 receives the use end message of being notified by user's Information Management Department 2203 ("Yes" of step 2706), judge whether the use end message of being notified is a plurality of (steps 2707).When the use end message of being notified has only one ("Yes" of step 2707), should use end message to be notified to end message management department 2204.
End message management department 2204 retrieves the end message of being preserved, and extracts notified location information of terminals (step 2708) when receiving the notice of using end message.In the example of Figure 24, F=2, X=10, Y=30 that end message management department 2204 extracts as the positional information of specified use terminal " tanaka_pc ", as the 3m of positional precision, and as obtaining 2003/1/10 17:20 of position time.
When end message management department 2204 does not preserve notified location information of terminals or is judged as ("No" of step 2709) need obtain positional information once more the time, (step 2710) handled in the renewal of executing location information.
As being judged as the condition that to obtain positional information once more, can consider following method: when the request that receives from user's information treatment part 2202, the position acquisition time and the current time of specified use terminal are contrasted, if, then be judged as and obtain positional information once more than older information during predetermined.At this moment, be 2003/10/10 17:40 for example when the current time, and stipulated the information more than 15 minutes is upgraded, and the position acquisition time of the positional information of being preserved is judged as and need obtains positional information once more when being 2003/1/10 17:20.
In addition, the update method of the end message of being preserved as end message management department 2204, judge that whether it is necessary or not when the demonstration request that has from the viewer and upgrade the method for processing except above-mentioned, also can adopt the method for handling by the renewal of the regular enforcing location information of application server.In addition, the terminal type of being preserved when user's Information Management Department that uses terminal also can not carry out the renewal of positional information and handle during as the wired lan terminal.
In addition, in the renewal of positional information was handled, end message management department 2205 carried out the request of the location of designated terminal by location-server interface portion 2206 to location-server 109.Location-server 109 will determine that the result of the position of terminal sends to location-server interface portion 2206, and location-server interface portion 2206 passes to end message management department 2205 with this information.Information such as location information of terminals and positional precision are determined to comprise among the result in the position of terminal.End message management department 2205 receives this result, and upgrades positional information, positional precision and position acquisition time etc.When failure is determined in the position, both can when being made as the sky hurdle, positional information and positional precision upgrade the position acquisition time, can in store positional information content not upgraded yet.
When end message management department 2205 by the end message preserved of retrieval or upgrade positional information and when successfully obtaining the use location information of terminals of being notified ("Yes" of step 2711), end message management department 2205 replys positional information, positional precision, position acquisition time etc. to user's information treatment part 2202.On the other hand, when failing to obtain the use location information of terminals of being notified ("No" of step 2711), carry out necessary fault processing (step 2716).
In step 2711, user's information treatment part 2202 also can be to using terminal to reply affirmation.At this moment, for example can consider to use PING procotols such as (Packet INternet Groper, packet internet groper) to confirm whether this terminal is in structure of the state that is connected with network or the like.In addition, even also can constitute, be judged as the structure of failing to obtain positional information when getting access to positional information when also failing to confirm replying of self terminal.
The user's information treatment part 2202 that has obtained location information of terminals from end message management department 2205 is in order to determine the position with the user of user's name appointment, generate display message based on these information based on character, perhaps obtain this floor maps and generate the information etc. of icon display in floor maps, send it to user's position display unit 2207 then and show (step 2712) from floor maps management department 2206.
Then, user's information treatment part 2202 judges whether the demonstration of appointed all users' positional information finishes (step 2713), when all users' processing finishes ("Yes" of step 2713), finishes all to handle.Do not finish when handling, also surplus when the user is arranged ("No" of step 2713), the step that repeating step 2704 is later.
The positional information of step 2712 shows to handle both can carry out according to each user as shown in figure 27 like that, also can obtain processing end back (after the "Yes" of step 2713) in all users' positional information and show.In addition, though also can constitute under the situation of the positional information of failing to obtain appointed user, also in user's position display unit 2207, show not the structure of processing.In addition, can be following structure: in step 2701, when the floor name of having specified the current place of viewer, and the user's who is obtained positional information and viewer's floor be not simultaneously, does not show or do not show to exist yet.
Below, with reference to Figure 27 and Figure 28, the operation of the application server 110 the when user that viewed person's appointment is described uses many station terminals.Is that example describes to have specified the user name for the situation of " Jiro Sato ".
Extract the result of the use end message corresponding by user's Information Management Department 2203, extracted a plurality of use end messages ("No" of step 2707) with specified user's name of user's information treatment part 2202 or user ID.In the example of Figure 23, as the use end message of user's name " Jiro Sato ", determined " sato_pc " and " sato_pc2 ", and used end message and terminal type to be notified to user's information treatment part 2202 these.
User's information treatment part 2202 is replied affirmation (step 2801) to each terminal of described a plurality of terminals after these information of reception.As the method for replying affirmation, also can for example use procotols such as PING to confirm whether this terminal is in the state that is connected with network.
When coming the replying of self terminal ("Yes" of step 2802), user's information treatment part 2202 extracts the use terminal (step 2803) of replying, and this is notified to end message management department 2204.Whether notified end message management department 2204 retrievals are preserved and are used location information of terminals (step 2804), and judge whether to carry out the renewal (step 2805) of positional information.
When the result who judges is ("No" of step 2805) when needing the renewal positional information, carry out the renewal (step 2806) of positional information.The processing of step 2805 and step 2806 is identical with the processing of step 2709 and step 2710.
When the result who judges for need not to upgrade positional information, when perhaps after upgrading positional information, successfully getting access to the use location information of terminals ("Yes" of step 2807), judge whether the use terminal that positional information is successfully obtained only has one (step 2808).
When the use terminal of successfully being obtained when positional information only has one ("Yes" of step 28708), select this use location information of terminals (step 2809).On the other hand, the use terminal of successfully being obtained when positional information has ("No" of step 2808) when a plurality of, and having judged whether to obtain terminal type is the use location information of terminals (step 2810) of Wireless LAN terminal.
When successfully to get access to terminal type be the use location information of terminals of Wireless LAN terminal ("Yes" of step 2810), select this use location information of terminals (step 2811).In step 2811, when existing a plurality of terminal types to be the use terminal of Wireless LAN terminal, use location information of terminals from wherein selecting one.As choice criteria herein, for example can consider following method: for example make end message management department 2204 collect user such as key inputs and using terminal information, and selected to have carried out at last the use location information of terminals of key input.
When to fail to get access to terminal type be the use location information of terminals of Wireless LAN terminal ("No" of step 2810), selecting terminal type is the use location information of terminals (step 2812) of wired lan terminal.In step 2812, when having a plurality of use terminal, use location information of terminals from wherein selecting one.As choice criteria herein, for example can consider following method: for example make end message management department 2204 collect user such as key inputs and using terminal information, and selected to have carried out at last the use location information of terminals of key input.

The 6th embodiment
As the embodiment different with second embodiment with the first above-mentioned embodiment, the following describes with warehouse etc. in the relevant embodiment of location management system such as the moving bodys such as goods transport systems of forklift etc.For structure same as the previously described embodiments, be marked with identical label and detailed.In addition, because its structure and above-mentioned first embodiment are basic identical, therefore, be that the center describes with the part different with first embodiment.
Figure 66 is the structural representation of present embodiment.In the present embodiment, suppose to use the use optical signal transmitting portion in the emission part that in first embodiment, illustrates, especially use infrared signal to launch the emission part of ID.
In Figure 66, the Q104 of optical signal detecting portion that is installed in sensitive surface mode up on the forklift Q103 etc. from the peculiar information of emission part Q101～Q102 emission receives, and is notified to terminal Q105 then.Terminal Q105 will be notified to location-server Q107 by base station Q106 from the peculiar information of the Q104 of optical signal detecting portion notice.The structure of the Q104 of optical signal detecting portion, terminal Q105 etc. in the present embodiment and processing are identical with first embodiment.
In the present embodiment, if can be covered by the sending zone of a plurality of emission part Q101 etc., then always can capture the position of forklift Q103 as the whole warehouse of the object of location management.
On the other hand, as long as such as under knowing that area, forklift place is with regard to passable situation, can consider the only method of configuration emission part Q101 on passage.Figure 67 shows the example of watching inside, warehouse from above.
In Figure 67, suppose that Q201～Q206 is the area at forklift place.Suppose between area Q201～Q203 and area Q204～Q206 to be provided with the passage that forklift passes through, forklift must pass in and out each area by this passage.
So,, then just can lock the area at forklift place to a certain extent by the peculiar information of analyzing the forklift reception if the boundary member in each area on passage is provided with sending zone Q207～Q210.For example, when forklift has received the peculiar information of sending zone Q207 and Q208, can judge forklift or be arranged in the some of area Q202 or Q205, or on the passage between these areas.
As the method for the forklift positions in the management warehouse,, it is also conceivable that shown in Figure 68 from horizontal methods that sends peculiar information such as pillars except sending the method for peculiar information shown in Figure 66 from ceiling.At this moment, emission part Q302 so that the horizontal mode of light emission direction be installed on pillar Q301 in the warehouse etc.
Similarly, the Q304 of optical signal detecting portion also is installed on the forklift Q303 in the horizontal mode of sensitive surface.Shown in Figure 68, two Q304 of optical signal detecting portion, Q305 are installed, make its sensitive surface separately with respect to the direction of advance of forklift Q303 towards right-hand and left.Like this, by two optical signal detecting portions are mounted to towards right-hand and left, and judge it is which optical signal detecting portion has received the peculiar information from emission part Q302, can detect forklift Q303 with respect to emission part Q302 towards which direction.
Illustrate under situation about emission part laterally being installed on the pillar to carry out what kind of location management with reference to Figure 69 shown in Figure 68 to forklift.
Identical with Figure 67, the example when Figure 69 shows area to forklift place in the warehouse and manages.Here, in the example of Figure 69, suppose in the passage both sides to have pillar Q401～Q408.Here, the situation of for example considering that emission part is installed and send peculiar information to pillar Q403 direction on pillar Q401.Figure 70 shows the partial enlarged drawing of pillar Q401 and pillar Q402.Shown in Figure 70, emission part Q501 is installed on the pillar Q401, and launches peculiar information to the direction of pillar Q403.Represent to receive from the zone of the peculiar information of emission part Q501 emission with reference number Q502.
Shown in Figure 70, the transmitting powers of adjusting emission part Q501 etc. are so that regional Q502 is no more than pillar Q403, thus, when the optical signal detecting portion on being installed in forklift receives from the peculiar information that emission part Q501 sends, can detect the discrepancy of the area Q204 of the relative Figure 69 of forklift.
Here, shown in Figure 68 like that with two Q304 of optical signal detecting portion, Q305 towards direct of travel and towards right and be installed on the both direction on a left side under the situation on the forklift Q303, when receiving at the Q304 of optical signal detecting portion that installs towards direct of travel towards the right side on the forklift Q303, can judge that forklift Q303 has entered area Q204 from peculiar information that the emission part Q501 of Figure 70 sends.
Similarly, when the Q305 of optical signal detecting portion that installs towards direct of travel towards a left side receives from peculiar information that emission part Q501 sends, can judge that forklift Q303 has entered area Q204.
Figure 71 shows other method that emission part is installed on pillar.In Figure 71, emission part Q601 and Q602 are installed in respectively on pillar 401 and the pillar 403, and send peculiar information face-to-face.Represent sending zone with reference number Q603, Q604 from the peculiar information of each emission part.The advantage that two emission parts are installed like this is to regulate easily the output of emission part.
In Figure 70, though need to regulate transmitting power so that the zone that can receive from the peculiar information of emission part Q501 does not exceed pillar Q403, if but transmitting power too a little less than, then can near the pillar Q403 in the area between pillar Q401 and the pillar Q403, produce and to receive the zone of peculiar information, thereby can't detect the discrepancy of forklift.Therefore, in the structure of Figure 70, need accurately to regulate the transmitting power of emission part Q501.
Relative with it, when shown in Figure 71, sending respectively under the situation of peculiar information from emission part Q601, the Q602 that is installed on the pillar of both sides, when receiving the peculiar information of either or both, forklift Q303 just can judge that forklift comes in and goes out with respect to the area, therefore, even if sending zone Q603, the Q604 of each emission part more or less overlap, and be also no problem.Thus, there is the advantage of regulating the transmitting power of emission part Q601, Q602 easily.
But, in the structure that reference Figure 68～Figure 71 describes, when forklift Q303 (retreats) when mobile backward, only with the optical signal detecting portion that has received peculiar information towards the discrepancy that can't judge with respect to the area, therefore, in order to judge the discrepancy with respect to the area, needing forklift is in the additional information of advancing or retreating.Perhaps, also can consider to judge the trend of forklift according to the history that is installed in the peculiar information that the optical signal detecting portion on the forklift received.
For example, when the optical signal detecting portion on the forklift Q303 of being installed in is receiving the peculiar information that sends between pillar Q401 and pillar Q402 after, when receiving the peculiar information that between pillar Q401 and pillar Q403, sends again, can judge that forklift Q303 has entered area Q204 from passage.In addition, when receiving the peculiar information that between pillar Q401 and pillar Q403, sends once more afterwards more than the continuous process certain hour, can judge that forklift Q303 may leave area Q204 from passage.At this moment, can be to have left really by being received in the peculiar information that sends between other the pillar by the optical signal detecting portion that is installed on the forklift Q303, judging from area Q204.
Identical with Figure 70 and Figure 71, if send peculiar information emission portion installing between the pillar Q401 of passage both sides and pillar Q402 etc., can judge then forklift Q303 is positioned at which area on the passage.
In Figure 66～Figure 71, to the example of forklift as the object that carries out location management is illustrated, but also can consider to be applied to operating personnel carries the situation of the PDA terminals such as (Personal Digital Assistant, personal digital assistants) with optical signal detecting portion or optical signal detecting portion is installed in situation on the helmet or the like.In addition, the place of carrying out location management also is not limited to the warehouse, can consider to be applied to various indoor environments such as factory and love scene.
As with the system of the system similarity that in Figure 68～Figure 71, illustrates, can enumerate system by the discrepancy of using detection light such as infrared ray sensor to be blocked to survey people etc.But native system and in the past the difference of system be can determine to enter into the forklift in area.In system in the past, pass through though can detect object, can not determine the object that passes through.To this, in native system, the Termination ID by each terminal that will distribute on the forklift to be installed sends to server, can determine which forklift enters into the area.
