Operation is controlled handling part 32 as is shown in Fig. 4, has passenger's confirmation unit 32A, the passenger position observation 32B of portion, the abnormal communicating department 32C of passenger, relief judging part 32D in function.
Passenger's confirmation unit 32A is to having or not passenger to confirm in car.The passenger position observation 32B of portion is the pattern that need to observe certain hour by working mode transition in the situation that passenger position has occurred to change, and passenger's position is observed.The abnormal communicating department 32C of passenger, being judged as passenger position state based on passenger position in abnormal in the situation that, passes to relay transmission portion 33 by essential information.Relief judging part 32D, judges being judged as the passenger's of abnormal state relief.
Relay transmission portion 33 is being judged as passenger status when abnormal with the abnormal communicating department 32C of passenger, will to inside-plant passenger, give first aid to chamber 40 to carry out relaying to abnormal relevant view data and/or various sensor information.The passenger chamber of rescue is monitoring room, guard chamber, handler chamber etc.
Also have, passenger gives first aid to chamber 40 to be at least provided with control monitor unit 41.This control monitor unit 41, for example with respect to the salvor who is waiting for, is succoured passenger for it is caught up with in car, has the function to comprising that the image relevant to abnormal state passenger position abnormal circular and essential data show.
Passenger gives first aid to chamber 40 also can be equivalent to the Long-Range Surveillance Unit being connected with control board for elevator 3 by communication networks such as telephone communication circuit, LAN.
Next, the work about as with the abnormal reporting chain of passenger in the car that Shangdi was formed, describes with reference to Fig. 5.
First, operation is controlled handling part 32 and by elevator user, boarding place call button is operated, and carries out the registration that this boarding place is called out floor.Then, operation control handling part 32 drives towards car 6 by towing machine 4 and calls out registration floor.If car 6 arrives at, call out registration floor, operation control handling part 32 makes car door 6b open.
Now, operation is controlled handling part 32 and is made passenger's confirmation unit 32A work of confirming into the passenger of car 6 taking advantage of.The output of this passenger's confirmation unit 32A based on being arranged at the place ahead and monitoring near the occupant detection sensor 13 camera 11f, to having or not passenger to judge (S1).At this, if be judged as, there is no passenger's ("No" of S1), passenger's confirmation unit 32A is standby mode (S2) by working mode transition.And the 32A standby of passenger's confirmation unit is until through predetermined certain hour, and after this standby time ("Yes" of S3) again to having or not passenger to judge (S3 → S1).
At this, if be judged as passenger's ("Yes" of S1), passenger's confirmation unit 32A to be pre-stored within recording device 31 presumptive area human characteristic graph data with a plurality of supervision camera 11f, 11b get into view data compare.Passenger's confirmation unit 32A, based on this comparative result, obtains passenger position (coordinate) and number, and the number information that this is obtained is recorded in recording device 31 (S4).
Then, operation is controlled handling part 32 and is made the passenger position observation 32B of portion work.
This passenger position observation 32B of portion, the passenger position based on this time obtaining by passenger's confirmation unit 32A and last registration, in the passenger position of recording device 31, have unchanged judge (S5) to passenger position in car.In the unconverted situation in position ("No" of S5), operation is controlled the motionless enforcement of handling part 32 former state and is conventionally moved control (S6).Handling part 32 is controlled in operation, after car 6 arrives at object floor, if car door 6b detected, closes (S7), turns back to step S4, repeats to implement same processing.
In step S5, in the situation that the passenger position observation 32B of portion is judged as passenger position and changes ("Yes" of S5), the output based on passenger's fall detection sensor 14 judges that the output of passenger's car floor sensor whether accumbency or the vibration based on causing falling because of passenger detect in car judges whether to have produced the vibration (S8) of falling and causing because of passenger.
Also have, the passenger position observation 32B of portion also can be with passenger's fall detection sensor 14 logical AND (AND) condition with the output of car floor sensor, the location status that is judged as passenger exists abnormal.Or, the passenger position observation 32B of portion, as long as at least the output based on passenger's fall detection sensor 14 is judged as passenger's accumbency, even if car floor sensor does not detect vibration, the location status that also can be judged as passenger exists abnormal.
The passenger position observation 32B of portion is judged as passenger standing place in step S8 not to be had to change, at this, be that passenger is not in car, accumbency and car floor sensor detect vibration in the situation that ("No" of S8), the passenger position observation 32B of portion is needs observing pattern (S9) by working mode transition, standby is until need the schedule time (S10) of observing pattern through this, and changes step S8 into and repeat same processing.
In the situation that the passenger position observation 32B of portion is judged as passenger accumbency or car floor sensor in car and vibration detected in step S8 ("Yes" of S8), operation is controlled handling part 32 and is made the abnormal communicating department 32C work of passenger.The abnormal communicating department 32C of this passenger is sent to relay transmission portion 33 (S11) by the abnormal circular of passenger from recording device 31, and is for waiting for the abnormal patterns of relief by working mode transition.The abnormal circular of this passenger at least comprises that passenger's location status becomes the output etc. of view data, passenger's fall detection sensor 14 and the car floor sensor of the time period before and after the abnormal moment or its.At this, relay transmission portion 33 by the various passengers that obtain from the abnormal communicating department 32C of passenger extremely circular information send to passenger to give first aid to chamber 40, and make it to be shown in control monitor unit 41.
As in 41 pairs of passenger's examples that circular information shows extremely of control monitor unit, can enumerate the situation that the output state of view data, passenger's fall detection sensor 14 and car floor sensor is shown.But from the viewpoint that passenger position abnormal state is reported in early days, control monitor unit 41 exists extremely and reports passenger position state with audio mail, or by making abnormality alarm ring, impel overseer to observe control monitor unit 41.In addition, in the situation that there is multi-section numbering of elevator machine, it is which numbering of elevator machine specifically identifies title on earth that control monitor unit 41 also will show abnormal generation source.
On the other hand, operation is controlled handling part 32 after abnormal communicating department 32C has carried out the abnormal circular of passenger by passenger, forces to make car 6 to arrive at nearest floor, and door is opened wide, the standby (S12) in order to accept relief along with the transformation to abnormal patterns.
Next, operation is controlled handling part 32 and is made to succour judging part 32D work.
Rescuer gives first aid to chamber 40 directly or based on give first aid to the contact of chamber 40 from passenger from passenger, and rushes for scene.Relief judging part 32D until rescuer arrive at during, is judged as rescuer and not yet arrives ("No" of S13), and until the button 18 that arrives at of guidance panel 15 is operating as only standby (S14, S15).
If arrive at corresponding car 6, rescuer operates the button 18 that arrives at of guidance panel 15.So relief judging part 32D is judged as rescuer and arrives at ("Yes" of S13).After this judgement, rescuer guides to boarding place floor (floor) by being judged as the abnormal passenger of location status in car 6.Then, if rescuer operates ("Yes" of S16) to carriage return button 19, operation control handling part 32 is conventionally operation master mode by working mode transition, makes the common restoring running of car 6.
Thereby, according to above embodiment, in car, the abnormal reporting chain of passenger is confirmed passenger's this situation in car 6 that enters, and as long as passenger's position changes, the at least output based on passenger's fall detection sensor 14, having there is variation in the standing place passenger, that is to say that passenger, because of in passenger's crowded situation of falling down, due to illness falling down suddenly each other, can detect passenger's location status immediately extremely.
And, if make the testing conditions of passenger position abnormal state become the logical AND condition of output and the output that car floor sensor produces of passenger's fall detection sensor 14, in car, the abnormal reporting chain of passenger can more correctly detect passenger's the state of falling.
And, if the abnormal state of passenger position in car detected, in car, the abnormal reporting chain of passenger will comprise monitoring image constantly of the captured abnormality detection of camera 11f, 11b or comprise the image of time of time period before and after it and/or the passenger of the output data of passenger's fall detection sensor 14 extremely circulates a notice of communication and gives first aid to chamber 40 to passenger.Thereby, can make rescuer hurry to the scene.
And the abnormal reporting chain of passenger, after circular passenger circulates a notice of information extremely, forces to make car arrive at nearest floor in car, door is opened wide and enter readiness for action.Thereby, can eliminate the uneasiness sense that is stranded caused passenger in car due to the passenger who falls down.Also have, now, if broadcast urgency message from the rattler in car, to outside this content, can further give passenger with the sense of feeling at ease.
On the other hand, if rescuer operates arriving at button 18, and after passenger having been carried out to relief, carriage return button 19 is operated, operation control handling part 32 can change mode of operation into common operation master mode from abnormal patterns.
