Detailed description of the invention
Be described referring to the embodiment of accompanying drawing to elevator device 300 involved in the present invention.Fig. 1 is the diagram of block of elevator device 300, there is shown the passenger (elevator user) that carries mobile terminal 10 and sends situation when remote call-in logs in or calling logs in cancellation indicates to elevator 40.Radio transmitters 20 and wireless receiver 30 is provided with near elevator 40.Communication line 45 is provided with between elevator 40 and radio transmitters 20 and between elevator 40 and wireless receiver 30.
Mobile terminal 10 receives the wireless signal sent from radio transmitters 20, and from mobile terminal 10, wireless signal is sent to wireless receiver 30.Because radio transmitters 20 is connected with elevator 40 by communication line 45 with wireless receiver 30, so the setting place of radio transmitters 20 and wireless receiver 30 is unrestricted.
Such as, radio transmitters 20 can be arranged on the entrance of the building being provided with elevator 40, wireless receiver 30 is arranged on elevator lobby.The setting place of radio transmitters 20 and wireless receiver 30 also can be exchanged and wireless receiver 30 is arranged on the entrance of building, and radio transmitters 20 is arranged on elevator lobby.And also radio transmitters 20 and wireless receiver 30 all can be arranged on elevator lobby.
The operation program of the various piece that the elevator device 300 with said structure has below is described.The radio transmitters 20 be arranged near elevator 40 ceaselessly sends wireless signal (step S10) continuously.After passenger approaches elevator 40, the mobile terminal 10 entrained by passenger receives the wireless signal (step S20) sent from radio transmitters 20.
Be confirmed whether to be connected (step S30) with wireless receiver 30 in mobile terminal 10.Confirm as also do not complete connection time, mobile terminal 10 sends connection request (step S40) to wireless receiver 30.Wireless receiver 30 receives the connection request (S50) sent from mobile terminal 10, and sends connection license (step S60) to mobile terminal 10.
According to the signal sent from wireless receiver 30, mobile terminal 10 confirms whether the connection request that self sends obtains license (step S70), when not having to confirm, turns back to receiving condition and step S20.When confirming as connection request and securing permission, be judged as connecting and set up (step S80).Owing to being connected with wireless receiver 30, so the electric wave intensity that mobile terminal 10 is received sends to wireless receiver 30 (step S90).Mobile terminal 10 returns step S20 after transmission terminates, and enters the state of the signal that wait-receiving mode sends from radio transmitters 20.
Now, wireless receiver 30 receives the received signal strength (step S100) sent from mobile terminal 10, the received signal strength received is sent to elevator 40 (step S110).Wireless receiver 30, after transmission and reception signal strength, returns step S100, enters the state of wait-receiving mode from the received signal strength of mobile terminal 10.On the other hand, elevator 40 receives the received signal strength (step S120) sent from wireless receiver 30.
Due to mobile terminal 10 and the information exchange routine between radio transmitters 20, wireless receiver 30 and elevator 40 are arranged to the program shown in Fig. 2, so when the received signal strength only received at mobile terminal 10 reaches the intensity can setting up wireless connections, signal can be sent from mobile terminal 10 to elevator 40.Therefore, the occasion of wireless transmission can carried out effectively, can from mobile terminal 10 one by one to elevator 40 transmission and reception signal strength.
In the above-described embodiments, radio transmitters 20 and wireless receiver 30 are individually formed, but also radio transmitters 20 and wireless receiver 30 can be united and used radio access point (wireless aps) 50.Fig. 3 represents the diagram of block of the elevator device 300 being provided with wireless aps 50.In wireless aps 50, radio transmitters 22 and wireless receiver 32 one are formed.Other structure is identical with the occasion of Fig. 1.
In the example depicted in fig. 3, by using wireless aps 50, the occasion formed separately separately with radio transmitters 20 and wireless receiver 30 is compared, although the degree of freedom arranged declines to some extent, arranges and becomes convenient.In addition, by wireless aps 50 is arranged on elevator lobby, along with carrying the passenger of mobile terminal 10 near elevator 40, received signal strength is grow gradually.On the contrary, along with the passenger carrying mobile terminal 10 leaves elevator, received signal strength dies down gradually.Therefore, by monitoring received signal strength, the moving direction of passenger can be known.
In the following description, assumed wireless transmitter 20 and wireless receiver 30 are arranged in wireless aps 50.
Then illustrate that received wireless received signal strength is sent to the timing of wireless receiver 30 by the mobile terminal 10 receiving the wireless signal sent from radio transmitters 20 with reference to Fig. 4.Fig. 4 represents mobile terminal 10 diagram of circuit of the process of the receiving intensity of signal that sends to the radio transmitters 20 that wireless receiver 30 sends in wireless aps 50 of interval at regular intervals.
Time meter that mobile terminal 10 is had by self confirms to enter and receives institute's elapsed time (step S200) after initial state.If also not through the elapsed time of starting at from reception initial state preset, Updating time, and the state (step S210) entering wait-receiving mode.When have passed through the elapsed time preset, receiving the wireless signal (step S20) sent from radio transmitters 20, and received signal strength being sent to wireless receiver 30 (step S90).After the transmission of received signal strength terminates, mobile terminal 10 makes time meter make zero (step S220), and turns back to the step S200 confirmation elapsed time.
As the method determining the above-mentioned time preset, various method can be listed.Such as, the difference of supposition precision that changes because of the miles of relative movement of the passenger of elevator 40 of the above-mentioned time preset and different.The above-mentioned time preset also can be decided according to the correlationship of the distance between radio transmitters 20, the change of received signal strength of sending and the moving velocity of elevator 40 passenger.
Illustrate that referring to Fig. 5 received wireless received signal strength is sent to other timing of wireless receiver 30 by the mobile terminal 10 receiving the wireless signal sent from radio transmitters 20.In the example depicted in fig. 4, according to certain timing from mobile terminal 10 to wireless receiver 30 transmission and reception signal strength, and in this example, the only ability transmission and reception signal strength when received signal strength there occurs change.Namely carry out the transmission of so-called event-driven (Event Driven) mode.Fig. 5 is by the diagram of circuit of mobile terminal 10 to the process of wireless receiver 30 transmission and reception signal strength according to the change of the signal strength received.
Mobile terminal 10 receives the wireless signal (step S20) sent from radio transmitters 20, and is stored in by the wireless received signal strength received in the memory cell that self has (step S230).Previous signal strength is also stored in this memory cell.By the previous received signal strength that is stored in this memory cell compared with this received signal strength received, to calculate variable quantity (step S240) between the two.
Judge the threshold value (step S250) whether having exceeded the variable quantity preset by calculating the variable quantity obtained.When the variable quantity calculated is less than threshold value, turn back to step S20, continue to receive the wireless signal sent from radio transmitters 20.When the variable quantity calculated has exceeded threshold value, be considered as there occurs event, and received signal strength sent to wireless receiver 30 (step S90).
As mentioned above, be event driven program due to signal sets will be sent from mobile terminal 10 to wireless receiver 30, so and at regular intervals interval from mobile terminal 10 compared with the occasion of wireless receiver 30 transmission and reception signal strength, the transmission times to wireless receiver 30 can be reduced.Such as, when elevator 40 passenger rests on a place, when namely large change does not occur received signal strength, do not need transmission and reception signal strength, the communication frequency with wireless receiver 30 can be reduced thus.
Below illustrate and utilize the wireless received signal strength distribution of sending from radio transmitters 20 to infer that passenger takes into the method for the track (namely line of flow) till elevator 40.Fig. 6 represent the electric wave sent from the radio transmitters 20 be arranged near elevator 40 front received signal strength distribution 60 and obtain this received signal strength distribute 60 time the shape of mapping Figure 70 that uses.Fig. 6 (a) be superpose on the planar view of elevator 40 periphery received signal strength distribution 60 and the figure that obtains, Fig. 6 (b) be obtain this received signal strength distribute 60 time the example of mapping Figure 70 that uses.In addition, Fig. 6 (c) be superpose on the planar view of elevator 40 periphery received signal strength distribution 60 and passenger's mobile route and the figure that obtains, Fig. 6 (d) represent obtain this received signal strength distribute 60 time the shape of other mapping Figure 71 that uses.
Near the front side of elevator 40, be provided with radio transmitters 20, and be formed with substantially rectangular elevator lobby 42 in the front of radio transmitters 20, the width of this elevator lobby 42 is slightly wider than elevator 40.The main channel of the wider width taking into elevator for passenger is formed in the anterior end of elevator lobby 42.The width passage 44 narrower than main channel is formed at the sidepiece on the right side of elevator lobby 42.
As above arranging and be formed with the occasion of radio transmitters 20 and elevator lobby 42 and passage 44, by distributing 60 split into grid shapes and obtain mapping Figure 70 by the received signal strength of the actual measurement of sending from radio transmitters 20 or by the received signal strength that numerical operation is obtained.The occasion of the mapping Figure 70 shown in Fig. 6 (b), carries out the segmentation of wide degree by elevator lobby 42 and passage 44 and forms grid 72 on fore-and-aft direction and left and right directions, and the received signal strength near this grid 72 is distributed to each grid 72.
The passenger carrying mobile terminal 10 is in order to take elevator 40 and move and by multiple grid 72.Its result, send from radio transmitters 20 and the wireless received signal strength received by mobile terminal 10 because of mobile terminal 10 via grid 72 difference and change, As time goes on change simultaneously.That is, be sent to wireless receiver 30 by the change of the received signal strength by mobile terminal 10 from mobile terminal 10, the moving state of passenger can be grasped in lift facility 40 side.
The wireless received signal strength received by mobile terminal 10 when the graphical representation passenger of Fig. 7 advances according to the mobile route shown in the line segment A-A ' of Fig. 6 and curve B-B '.Abscissa in figure represents the elapsed time, and ordinate represents received signal strength.Line of flow 82,84 is change curves of the received signal strength changed along with the movement of passenger.The line of flow 82 of passenger straight when going to elevator 40 from main channel (A-A '), along with passenger approaches elevator 40, corresponds to the distance between elevator 40, increases roughly in a linear fashion.On the other hand, when passenger's passage 44 from the side goes to elevator 40, because the received signal strength at side channels place is low, so initial received signal strength value is less.In addition, in the example of above-mentioned Fig. 6 and Fig. 7, because elevator lobby 42 and passage 44 are two-dimensional space, so mapping Figure 70 is set as two-dimensional space, and if three dimensional space time, then mapping Figure 70 is also set as three dimensional space.
Then infer that the method for line of flow 80 is described with reference to Fig. 8 one by one to according to the received signal strength repeatedly sent from mobile terminal 10.Fig. 8 represents the diagram of circuit searching for the example of line of flow 80 from mapping Figure 70 one by one.Fig. 8 (a) represents the process in elevator 40, and Fig. 8 (b) shows in detail the content of the path search processing (step S330) in this process.
Elevator 40 receives the electric wave that sent by mobile terminal 10 as received signal strength E
t0(step S300), and search for its value and mapping the received signal strength E of the electric wave that Figure 70 receives
t0close grid 72 (step S310).By the position (grid numbering) of grid 72 that extracts by searching for and received signal strength E
t0be stored in (step S320) in the memory cell self had temporarily.When extracting multiple grid 72, each grid 72 extracted is carried out to route searching (step S330) process be described in detail in following part.
Elevator 40 receives the received signal strength (step S340) newly sent from mobile terminal 10.The received signal strength newly sent now is set as E
t1.Elevator 40 receives and the received signal strength E stored before this to have in mapping Figure 70
t0multiple grids 72 in each grid 72 be starting point, search for its value and the received signal strength E newly to receive
t1close grid 72 (step S350).In this search, the grid 72 in a scope that search passenger may move to.
Be confirmed whether to exist the grid 72 (step S360) meeting above-mentioned search condition.When searching the grid 72 meeting above-mentioned condition, will receive before this and storing received signal strength E in the memory unit
t0be updated to the received signal strength E newly received
t1.That is, electric field strength E is used
t1grid 72 replace electric field strength E
t0grid 72 (step S370).
Due to know existence respectively with two electric field strength Es
t0and E
t1suitable grid 72, so the slope (value that the difference of received signal strength obtains divided by the distance between grid) (step S380) calculating received signal strength according to these grids 72.On the other hand, when not having to find to meet the grid 72 of above-mentioned search condition, due to the line of flow candidate of passenger can not be regarded as, so delete the grid 72 (step S390) as starting point.The combination (step S400) of search slope and the close grid 72 of the slope of received signal strength.
In this example, carry out two search, namely while carrying out searching for according to the electric field intensity value of Received signal strength, the slope according to the electric field intensity of Received signal strength is searched for simultaneously.By this method, many line of flow can be obtained from multiple starting point.Therefore, judge whether a certain bar line of flow to be considered as arriving the grid 72 (step S410) suitable with elevator 40 preset in elevator 40.When being judged as arriving grid 72, terminate the supposition (step S390) of line of flow 80.And when being judged as not arriving elevator 40, proceed the route searching of step S330.
Received signal strength more becomes stronger close to radio transmitters 20, and more leaves radio transmitters 20 and become more weak.Therefore, when the change slope of received signal strength is precipitous, the moving velocity that can be speculated as the passenger carrying mobile terminal 10 is fast, and can be speculated as elevator 40 passenger and be eager to hurry on a journey.Now, although passenger does not also arrive the grid 72 implemented elevator 40 and call out, the controller of elevator 40 still carries out hall call, by making elevator car arrives in advance, makes passenger can take into elevator in time.In addition, although radio transmitters 20 sends with stable output, being subject to the impact of the receiving function of the mobile terminal 10 that elevator 40 passenger holds, may there is large change in received signal strength.Therefore, in the search of received signal strength, need to calculate similarity.
In the estimation method of the line of flow shown in Fig. 8, the received signal strength of electric wave and slope thereof according to being sent to elevator 40 from mobile terminal 10 infer line of flow.But other method also can be adopted to replace said method.As shown in Figure 9, also line of flow 80 can be inferred according to the pattern of the received signal strength repeatedly sent by mobile terminal 10.The diagram of circuit of Fig. 9 represents that the example of line of flow 80 inferred in advance by elevator 40 according to the changing pattern of special received signal strength.
Be subject to the impact of the structure at the turning of building etc. or the material of wall, the change of received signal strength can produce certain moduli formula.Below the pattern that received signal strength changes is called changing pattern 90.From the change of received signal strength, extract the changing pattern 90 corresponding with turning or wall, determine concrete place thus.The grid 72 corresponding with locality and changing pattern 90 are stored in the mode of combination meter in the memory cell self had in elevator 40.
Figure 10 represents an example of this combination meter.The combination of the time dependent changing pattern 90 of receiving intensity with the position of the grid 72 of the locality of this changing pattern of generation is preserved in the mode of form 110.Such as, at grid position (10,30) place has occurred that As time goes on received signal strength produces the changing pattern of peak value, has occurred that As time goes on received signal strength carries out the changing pattern of S deformation at grid position (50,50) place.
Below return Fig. 9 to be described.In elevator 40, received received signal strength stores in the memory unit in the mode of time series data.The received signal strength (step S430) that elevator 40 mobile terminal receive 10 newly sends, and according to received received signal strength, time series data is upgraded (step S440).Then, elevator 40 extracts feature mode (step S450) from received signal strength time series data.Pattern match (step S460) is carried out to the feature mode of time series data and changing pattern 90, is confirmed whether to there is the changing pattern 90 (step S470) matched.
When confirming as the changing pattern 90 existing and match, determine the grid position (step S480) of the locality corresponding with this pattern.Owing to determining locality, so by determined grid 72 being marked and drawed on mapping Figure 70 to derive line of flow 80.When there is not the pattern matched, being judged as that the pattern that can extract from time series data of current point in time is insufficient, returning step S430, enter the reception readiness for action of the new received signal strength data of wait-receiving mode.
In the occasion of the elevator lobby that elevator lobby is the channel attached broad view with many etc., because radio wave propagation is good, so the variable quantity of received signal strength is merely able to detect according to the works at turning etc. or the change of wall material.By obtaining the changing pattern 90 changed along with time lapse being changed to the ad-hoc location of characteristic change and the received signal strength of this specific location of received signal strength as shown in Figure 10 in advance, can infer in above-mentioned place and line of flow 80.
Due to the line of flow 80 elevator 40 passenger can be inferred, so passenger does not need in elevator 40 car and elevator lobby carries out the calling login of elevator 40 or calls out the cancellation logged in, and can carry out calling out the cancellation logging in or call out login with remote mode before taking into elevator 40.Carry out elevator 40 referring to Figure 11 and Figure 12 to the line of flow 80 that elevator 40 goes out by inference to call out or the method for cancelling calling is described.Figure 11 be along with passenger close to or grid 72 position of leaving the regulation mapped on Figure 70 to carry out the diagram of circuit during cancellation that calling logs in or calling logs in of elevator 40.Figure 12 is the calling boundary treatment S550 represented in the login process shown in Figure 11, cancel boundary treatment S560 and take into the diagram of circuit of detailed content of boundary treatment S570.
When elevator 40 judges whether to need to carry out calling out the cancellation logging in or call out login, the position of being undertaken calling out by hypothesis elevator 40 passenger, determining the position that can take and determine these three positions, position that can cancel, can judging easily to log in or cancellation that calling logs in the need of carrying out calling out.These positions are called calling border 110, take border 120 and cancel border 130.Distance from each border 110 ~ 130 to elevator 40 is assumed to (calling border 110 distance to elevator 40) > (cancelling the distance to elevator 40 border 130) > (taking the distance to elevator 40 border 120).At this, in elevator 40, management represents the information having carried out logging in or eliminate login.In addition, by calling log in time meter measure from calling start at institute's elapsed time.
Elevator 40 adopts any one line of flow estimation method above-mentioned to infer line of flow 80, to obtain the direct of travel of elevator 40 passenger and current position.And, decide the grid 72 (step S500) suitable with current location according to the expression direct of travel of passenger and the information of current location, confirm determined grid 72 and call out border 110, take border 120 and cancel which border consistent (step S510) in border 130.
Passenger not on any one border above-mentioned time, confirm calling log in time meter (step S520).This is at which time point occur to confirm to call out.The occasion that time meter there occurs time-out is logged in calling, because this calling is the calling occurred before very early, probably lost efficacy in the lifting of current lift car, so cancel calling to log in time meter, and memory recall state (step S530).After this, in order to process new calling, return step S500, wait-receiving mode received signal strength.
When elevator 40 passenger is present in calling border 110, takes border 120 and cancels any one border in border 130, such as, determine its grid position (step S480) according to the step shown in Fig. 9.Then confirm passenger is arranged in which border (step S540) on above-mentioned three borders.
When inferring or be judged as that elevator 40 passenger is positioned at calling border 110, perform calling boundary treatment (step S550).Now, elevator 40 confirms the direct of travel (step S551) of passenger according to the change of line of flow.Confirm as be direction close to elevator 40 time, carrying out stored calls logging status (step S554) while calling logs in.Elevator 40 makes calling login time meter start timing, takes elevator 40 ready (step S555) for passenger is actual.
When the direct of travel confirming as elevator 40 passenger is the direction leaving elevator 40, confirm calling logging status (step S552).If undertaken calling out the state logged in by step S554, then cancel this login, and memory recall state (step S553).
When confirming to infer or be judged as that passenger is positioned at cancellation border 130 on the border by step S540, perform and cancel boundary treatment (step S560).Now, elevator 40 confirms the direct of travel (step S561) of passenger according to the change of line of flow.If leave the direction of elevator 40, be confirmed whether to have been undertaken calling out logging in (S562) by step S554.When having carried out logging in calling, cancel this login, and memory recall state (step S563).Log in owing to eliminating calling, so make calling log in time meter zero, be new login ready (step S564).
When the direct of travel confirming as elevator 40 passenger is the direction close to elevator 40, be confirmed whether to have been undertaken calling out logging in (step S565) by step S554.When having carried out calling out login, the possibility taking elevator 40 due to passenger is high, so calling login is maintained effective.When not carrying out calling and logging in, because passenger is close to elevator 40, so be considered as passenger, to take the possibility of elevator 40 high, again infers line of flow (step S566) according to the method shown in Fig. 8 or Fig. 9.
If confirming as elevator 40 passenger in the step S540 of Figure 11 has entered when taking border 120, elevator 40 has performed and has taken boundary treatment (step S570).Passenger be positioned at take border time, estimate that this passenger can take elevator 40 substantially.Therefore, elevator 40 confirms that in step S554, whether carried out calling logs in (step S571).When having carried out calling out login, making calling log in time meter zero, having made it possible to confirm whether passenger takes elevator (step S573).If when carrying out calling login and be in cancellation state (S553) in step S554, again infer line of flow according to the method shown in Fig. 8 or Fig. 9, it can be used as and judge that passenger takes elevator 40 or leaves the judgement material (step S572) of elevator 40.
As mentioned above, three borders are set according to the position at elevator 40 passenger place, thus elevator can according to the line of flow 80 of passenger judge easily passenger be close to and prepare taking elevator, still to merely walk past near elevator.Its result, elevator 40 can carry out calling out the cancellation logging in and call out login automatically.
Only the calling of lift car is logged in the examples described above and be illustrated, and passenger by logging in its destination floor that will go in advance in mobile terminal 10, such as when mobile terminal 10 is connected with wireless receiver 30, only need to elevator 40 sending destination floor information, just while login calling, the login of destination floor can be carried out.
According to above-mentioned steps, elevator 40 logs in by inferring that the line of flow 80 of passenger can carry out calling out automatically or calls out the cancellation logged in., because elevator 40 passenger does not now also know the action of elevator 40 side, so passenger needs to carry out to press entrance hall button etc. log in the meaningless action such as destination floor.Therefore, calling logs in and calls out the mobile terminal 10 entrained by cancellation notice passenger logged in by elevator 40.Referring to the diagram of circuit shown in Figure 13, Notification Method when notifying passenger is described.Figure 13 represents that elevator 40 will represent the example of having carried out calling out the message informing mobile terminal 10 logged in by radio transmitters 20.
In order to calling be logged in or call out the cancellation notice mobile terminal 10 logged in, first elevator 40 carries out calling and logs in (step S700).Then, elevator 40 will represent that having carried out calling out the message logged in sends to radio transmitters 20 (step S710) by the wireless receiver 30 connected by communication line 45.On the other hand, radio transmitters 20 receives the message (step S720) of being sent by elevator 40, and message is sent to mobile terminal 10 (step S730).
Message communicating be requirement must carry out the program of replying time, be set with the time-out of response.There occurs the occasion of time-out because mobile terminal 10 does not carry out replying, radio transmitters 20 sends the information (step S740) representing and cannot communicate to elevator 40.Now, elevator 40 confirms the message (step S750) representing communication failure.Elevator 40 confirms result of communication (step S760).In the occasion of communication failure, the condition notification passenger that calling cannot be logged in.Now, in order to make passenger carry out calling login in elevator lobby side, elevator 40 being stopped, cancelling the calling (step S762) logged in step S554.
During carrying out above action, if mobile terminal 10 have received the message (step S770) of sending from radio transmitters 20, then the message of sending is presented on the read out instrument self had (step S772).After this, mobile terminal 10 sends response (step S774) to message to radio transmitters 20.
When have sent the response of mobile terminal 10 to the message of sending from mobile terminal 10 to wireless receiver 30, wireless receiver 30 confirmation message response (step S742) of radio transmitters 20 by being connected by communication line 45.Then, acknowledgement messaging is sent to elevator 40 (step S744) as " communicating successfully ".Elevator 40 confirmation message in step S750.After this, judging result of communication (step S760), proceeding process when communicating successfully.
The cancellation that calling logs in or calling logs in is being shown in above-mentioned steps on mobile terminal 10, also the information that in mobile terminal 10, storage is relevant with the destination floor that passenger will go to can be arranged in, perform the step of the message authentication of the elevator 40 shown in step S750 according to the acknowledgement messaging of the mobile terminal 10 shown in step S774, transmit destination floor information thus.Now, if communicate successfully, then elevator 40 can also log in destination floor, thus can improve the degree of automation further.
Referring to Figure 14, the above-mentioned line of flow 80 being inferred elevator 40 passenger by elevator 40 is described, automatically carries out calling out the cancellation logging in or call out login, this thing is notified the countermeasure of the passenger after the mobile terminal 10 entrained by passenger.When the diagram of circuit of Figure 14 represents that elevator 40 have sent message that expression logged in and the instruction relative to this message by radio transmitters 20 to mobile terminal 10, mobile terminal 10 replys the example that this instruction requires.
Mobile terminal 10 is after radio transmitters 20 receipt message (step S770), the read out instrument of self shows message (step S772), carries out urging elevator 40 passenger input for the instruction of this message and destination floor (step S780).At this, instruction is " calling logs in " and " cancellation that calling logs in ".
As repeat-back, the instruction that passenger inputs by mobile terminal 10 and destination floor send to radio transmitters 20.Radio transmitters 20 confirms by wireless receiver 30 instruction (step S782) that mobile terminal 10 sends.Radio transmitters 20 sends instruction and destination floor (step S784) to elevator 40.Elevator 40 confirms the instruction of being sent by radio transmitters 20 and destination floor (step S786).
Then, elevator 40 is resolved (step S788) the instruction of sending and destination floor, when instruction logs in for calling, logs in (step S790) passenger named destination floor.When instruction is the cancellation of calling login, cancels the calling logged in and log in (step S792).
As mentioned above, before passenger takes into elevator 40, according to the line of flow of elevator 40 passenger, the intention of the passenger carrying mobile terminal 10 can be reflected in the calling automatically carried out by elevator 40 and log in.When the calling that there is no need logs in, logging in by cancelling the calling that there is no need, the operating efficiency of elevator 40 can be improved,
In the above-described embodiments, the transmission level when radio transmitters 20 be arranged near elevator 40 being sent signal is set as certain transmission level, but only transmission level is set as certain transmission level, and the received signal strength of certain level might not be obtained between the mobile terminal 10 of same position.Such as, be provided with the occasion of door in building, when door opening and closing, received signal strength can change a lot.
Illustrate that received signal strength to there occurs the search example of the grid 72 when sharply changing because of the opening and closing of door referring to Figure 15 and Figure 16.Figure 15 represents the status example of the door opening and closing received signal strength change list 200 recording received signal strength change, the line of flow generation step considering received signal strength change when the flow chart of Figure 16 is shown in building entrance and building and is provided with.The in this case search example of grid 72.
An opening and closing received signal strength change list 200 is provided with in the memory storage that elevator 40 has.In this opening and closing received signal strength change list 200, in the position of grid 72 being provided with door, store the received signal strength 212 when received signal strength 210 when door is opened and door are closed in mode side by side.Such as, in the position of door (20,30) being arranged at interior of building, when door is in open state, if when mobile terminal 10 is positioned at this position, then the received signal strength 210 of mobile terminal 10 is 60%.On the other hand, in same position (20,30), when door is in closed condition, the received signal strength 212 of mobile terminal 10 is 20%.Equally, forming door position (100, the 50) place with outside border, when door is in open state, the received signal strength of mobile terminal 10 is 15%, and when door is in closed condition, received signal strength is cut off (0%).
The method of the line of flow search using the door opening and closing received signal strength change list 200 with above-mentioned information to carry out is described referring to Figure 16.Figure 16 shows the step namely mapping in region of search and Figure 70 searches for or without door.After elevator device 40 receives the wireless received signal strength (step S800) sent from radio transmitters 20, confirm, in the search of former door opening and closing received signal strength change list 200, to confirm with or without door candidate (step S810).If when not finding the grid 72 as door candidate in former search, the grid 72 (step S820) that search coincide with the received signal strength of door opening and closing received signal strength change list 200, and store door candidate (step S830).If also do not find a candidate in this search, be judged as there is no a candidate.
If searched door candidate in the search of former door opening and closing received signal strength change list 200, then search for door opening and closing received signal strength change list 200 (step S840).Search changes the grid 72 (step S850) of the door section matched with the received signal strength received in step S800.When not searching with the grid 72 that door is suitable, cancel door candidate (step S860).When having searched with the grid 72 that door is suitable, being judged as that the probability that there is passenger near door is high, and having determined passenger position (step S870).
In the above-described embodiments, mapping Figure 70 generates uniform grid 72, and as shown in Fig. 6 (a), the change of received signal strength there is thickness, so carry out generating mesh according to this thickness, more accurately can determine line of flow.At this, as shown in Fig. 6 (d), generate and there is the mapping Figure 70 changing corresponding uneven grid 74,76 to received signal strength.
In mapping Figure 70 of Fig. 6 (a), due to grid 72 is formed as uniform grid, so need huge grid 72 memory capacity, and search needed for time long.And in this example, owing to only generating small grid 74 for received signal strength locally there is part jumpy, and large grid 76 is generated to the little part of change, so while reducing the memory capacity mapping Figure 71, search time can be shortened.
As mentioned above, according to the present embodiment and variation, the change of received signal strength of mobile terminal entrained by elevator 40 passenger away from elevator 40 car the line of flow of passenger can be inferred.Further, by inferring line of flow, can carry out in elevator side calling out the cancellation logging in or call out login, so the operating efficiency of elevator can be improved before passenger takes into elevator.
And, by at elevator setting radio access point (AP), the line of flow of elevator passenger can be inferred, so can accomplish that the occasion only taking the possibility of elevator large passenger carries out calling login according to the electric field intensity change on the electric field intensity mapping graph of the electric wave sent from AP.Meanwhile, because mobile terminal only needs to return received signal strength to elevator side, so do not need to export the transmission of mobile terminal side carry out universalization or unitize.
In addition, in above-mentioned the present embodiment and variation, by arranging the device logging in the high line of flow of frequency in advance, the time needed for line of flow supposition can be shortened.
