The movable type collection mixer 10c that is arranged on inspection pedal 5 moves to collect the running sound of passenger conveyors along with inspection pedal 5 together circulates when the monitored object passenger conveyors turns round.Again; As fixed type collection mixer, promptly be arranged on the collection mixer 10a of Machine Room, top 2 and be arranged on the collection mixer 10b of Machine Room, bottom 3, collect near the running sound of the passenger conveyors Machine Room, top 2 and the Machine Room, bottom 3 simultaneously with movable type collection mixer 10c.
This movable type collection mixer 10c and fixed type collection mixer 10a, 10b are as shown in Figure 2, have: the collection line 11 that converts tones into aud. snl. output; Convert the aud. snl. of collection line 11 outputs into wireless receiving and dispatching information portion 12 that wireless signal sends; Collection line 11 and wireless receiving and dispatching information portion 12 are provided the power suppling part 13 of power supply.In the collection mixer 10c (10a, 10b are too) that constitutes like this; When passenger conveyors turns round; In case power suppling part 13 provides power supply to collection line 11 with wireless receiving and dispatching information portion 12; Be about to be accompanied by the running sound that the running of passenger conveyors takes place and convert aud. snl. into by collection line 11, this aud. snl. is converted into wireless signal through wireless receiving and dispatching information portion 12 and sends.
Here, portable collection mixer 10c moves with 5 circulations of inspection pedal, and the collected passenger conveyors running sound in each place on the mobile route of pedal 4 is sent out as wireless signal.The wireless signal that is sent out from this movable type collection mixer 10c receives through control setup 20.Same, be arranged on the fixed type collection mixer 10a of Machine Room, top 2, collect the running sound of winch that near the figure the Machine Room, top 2 do not show and sprocket wheel etc., and the running sound when collecting a plurality of pedals 4 and passing through Machine Room 2, top.Again, be arranged on the fixed type collection mixer 10b of Machine Room, bottom 3, collect the running sound of sprocket wheel that near the figure the Machine Room, bottom 3 do not show etc., and the running sound when collecting a plurality of pedals 4 through Machine Room 3, bottom.
Though Fig. 1 illustrates the instance that portable collection mixer 10c only is arranged on an inspection pedal 5, collect mixer 10c and also can be arranged on the plural inspection pedal 5 again.
Here, on passenger conveyors, set the reference position, be provided with position detecting device 50 at this place, reference position.This reference position conduct is used for confirming the reference position of the detected unusual sound scene of movable type collection mixer 10c and is used to make the collection sound moment of fixed type collection mixer 10a, 10b and the collection sound moment synchronization basic standard position of portable collection mixer 10c.This reference position is arranged on the assigned position on the circulation mobile route of pedal band, and the position detecting device 50 that is arranged on this reference position detects the moment of inspection pedals 5 through this reference position.Therefore, this position detecting device 50 below is called the reference position and passes through sensor.
Like this; The reference position through sensor 50 in reference position that the inspection pedal 5 that is arranged at portable collection mixer 10c is stipulated in through this mobile route (for example; The horizontal part of lower floor as shown in Figure 1 etc.) the moment is to control setup 20 outgoing position detection signals.This reference position constitutes through sensor 50, for example, through proximity transducer and opto-electronic pickup etc. are set in the reference position, the metal sheet that is used to discern this inspection pedal 5 etc. is installed in inspection pedal 5.Then, the detections such as proximity transducer and opto-electronic pickup that are arranged on the reference position are equipped with the passing through of inspection pedal 5 of metal sheet, and at this through outgoing position detection signal constantly.
Again, adopt proximity transducer and opto-electronic pickup as the situation of reference position, alternatively, also can in inspection pedal 5, inclination sensor be set through sensor 50 though illustration has.At this moment, the reference position for from the horizontal part of lower floor to place that rake moves.That is, inspection pedal 5 is when the horizontal part of lower floor moves to rake, and the rolling mechanism that the figure of pedal 5 does not show moves to heeling condition from horizontality, therefore, will to mobile moment at this angle of inclination as the moment through the reference position.
The control setup 20 of on-the-spot side; To be the running sound of passenger conveyors as the collection phenomenon that respectively collects mixer 10c and 10a, 10b of data collection module; Convert the voice data that can send into, and take care of as collecting data in each week of passenger conveyors (running).Promptly; Based on the detection signal of reference position through sensor 50; From inspection pedal 5 through the reference position to next time through reference position take care of in each week till constantly, this is sent to the object of delivering letters of regulation through communication line by each all collection data certainly.Promptly; This control setup 20 receives the passenger conveyors that is sent out through movable type collection mixer 10c and fixed type collection mixer 10a, 10b collection sound, as the wireless signal sound that turns round; Be converted into voice data again; And, for example, send to Long-Range Surveillance Unit 30 as the central monitoring position of the object of delivering letters through communication lines such as telephone line 40 with the voice data of this passenger conveyors running sound.
In the control setup 20 that constitutes like this; In case collection mixer 10a, 10b, the collected passenger conveyors running sound of 10c are sent out as wireless signal from each collection mixer 10a, 10b, 10c during the passenger conveyors action; This wireless signal is promptly received by wireless receiving and dispatching information portion 21, is converted into voice data and is stored in memory device 23 through signal conversion part 22.Then, the voice data that is stored in the passenger conveyors running sound of memory device 23 is read with predetermined data unit, and is sent to the Long-Range Surveillance Unit 30 that is arranged on central monitoring position remotely through communication line 40 from data transmit-receive portion 24.
Here; Portable collection mixer 10c together circulates mobile with inspection pedal 5 and in the mobile route of inspection pedal 5, collects passenger conveyors running sound at various places point; Therefore; The passenger conveyors running sound that inspection pedal 5 rounds collected is stored in the memory device 23 as voice data successively, and the roughly omnidistance running sound of passenger conveyors is stored in memory device 23 as voice data like this, and can send it to Long-Range Surveillance Unit 30.
Again, foregoing for control setup 20, inspection pedal 5 is each through the reference position, promptly from the reference position through sensor 50 position detection signal is provided.Like this, control setup 20 can be with being stored in the memory device 23 as a data unit through the voice data of reference position to the passenger conveyors running sound that returns such week till this reference position again from inspection pedal 5.Again, Long-Range Surveillance Unit 30 read and sent to the voice data of the passenger conveyors of each all data cell running sound can from memory device 23.
Likewise; The collection mixer 10a that is arranged on Machine Room, top 2 also collects sound with movable type collection mixer 10c simultaneously with the collection mixer 10b that is arranged on the Machine Room, bottom; Therefore, can be used as a data unit through the reference position to the voice data of the passenger conveyors running sound that returns such week till this reference position from inspection pedal 5 is stored in the memory device 23.Again, the voice data of the running sound of the passenger conveyors of each weekly data unit can be from memory device 23 reading and sending to Long-Range Surveillance Unit 30.
Long-Range Surveillance Unit 30 comprises: be connected in communication line 40, receive the collection data that the control setup 20 from on-the-spot side sends over; Each all collection data that receives and the passenger conveyors collection data just often of trying to achieve are in advance compared, and judging has N/R abnormality juding portion.Promptly; This Long-Range Surveillance Unit 30 receives the voice data that the passenger conveyors running sound that sends over via communication line 40 of on-the-spot control setup 20 is set from passenger conveyors, is used to detect the abnormity processing of monitored object passenger conveyors based on this voice data.
This Long-Range Surveillance Unit 30, for example as shown in Figure 2, have data transmit-receive portion 31, data processing division 32 and abnormity notifying portion 33.Data transmit-receive portion 31 is connected with communication line 40, receives from the data transmit-receive portion 24 of control setup 20 via communication line 40 the turn round voice data of sound of the passenger conveyors that obtains of being delivered letters.It is unusual that data processing division 32, the voice data of the passenger conveyors running sound that data receiving and transmitting part 31 is received carry out that analyzing and testing monitored object passenger conveyors takes place.Abnormity notifying portion 33 gives the data analysis result notification of data processing division 32 through image or sound etc. the surveillant of central monitoring position.Further, the inside of data processing division 32 is provided with various memory of data 34 and the abnormality juding portion 35 that carries out abnormality juding of storing.
Be arranged at the internal storage 34 of the data processing division 32 of Long-Range Surveillance Unit 30, have following the 1st, the 2nd, the 3rd and the 4th illustrated data area.In the 1st data area, for each monitored object passenger conveyors, storage is provided with " on-the-spot place and passenger's the liaison method " of these passenger conveyors etc.In the 2nd data area, for each monitored object passenger conveyors, " specification data that passenger conveyors is intrinsic " of separately story height or trip distance of storage, angle of inclination, operating speed, rotation direction etc.In the 3rd data area, store " voice data just often " that the monitored object passenger conveyors just often adopts collection mixer 10a, 10b, 10c to obtain in advance.When for example being registered, collecting these data, and it is write each self-corresponding zone as the passenger conveyors of monitored object.
Again; In case the voice data of the passenger conveyors running sound that sends over from control setup 20 via communication line 40 is received by data transmit-receive portion 31; The data processing division 32 of Long-Range Surveillance Unit 30 is about to the voice data of this passenger conveyors running sound, with inspection pedal 5 around between one-period by collection mixer 10a, 10b, 10c collect one week amount each of data unit; Temporarily be stored in the 4th data area of internal storage 34, i.e. the data area of " supervision voice data ".
Data processing division 32 in-to-in abnormality juding portions 35; The voice data and the monitored object passenger conveyors that send to the passenger conveyors running sound of Long-Range Surveillance Unit 30 via communication line 40 from control setup 20 that collection mixer 10a, 10b, 10c is collected just often adopts collect mixer 10a, 10b, voice data just often that 10c obtained in advance compares, whether judgement monitored object passenger conveyors takes place unusually.
Promptly; Abnormality juding portion 35 reads " voice data just often " of the 3rd data area that is stored in memory device 34 in advance respectively; At any time " the supervision voice data " of the 4th data area of write store 34 is input to these voice datas in the comparator and compares.Here; " supervision voice data " and " voice data just often " that memory device 34 is read are respectively; With the inspection pedal 5 that the is provided with collection mixer 10c moment through reference position position to start with, the time series data of the passenger conveyors running sound that collection mixer 10a in the time in this pedal one week of 5 operations, 10b, 10c are collected.Abnormality juding portion 35 makes these " supervision voice datas " consistent with the starting position separately of " voice data just often " and be input to comparator; For example; Between " supervision voice data " and " voice data just often "; When the part of the difference that detects the sound press level that surpasses the abnormality juding threshold value of stipulating, it is unusual to judge that the monitored object passenger conveyors produces.
Again, abnormality juding portion 35 is judging that the monitored object passenger conveyors produces when unusual, and reading pre-stored is in " specification data that passenger conveyors is intrinsic " of the 2nd data area of memory device 34.Based on the comparative result of " supervision voice data " and " voice data just often " and " specification data that passenger conveyors is intrinsic " that from memory device 34, reads, confirm unusual scene then.
Specifically; When with cooresponding reference position, the starting position of voice data be that the rotation direction of horizontal part, the passenger conveyors of lower floor is the 30m/ branch, forms length when being 8m for the running of rising, operating speed; If begin from the data starting position, be 20 seconds by keeping watch on the time T that voice data is judged to be unusual part; Confirm that then inspection pedal 5 in the advance position of 10m of the horizontal part from lower floor, that is, takes place unusually near the Machine Room of the upper layer side from turning back in the upper strata after.Again; Since the trip distance of passenger conveyors can according to the story height of passenger conveyors and angle of inclination geom calculate; Therefore under the situation of the trip distance of not storing passenger conveyors, also can adopt the data at story height and angle of inclination to confirm unusual scene as specification data.
As stated; In case judge that through abnormality juding portion 35 this unusual scene takes place unusually, also to confirm the monitored object passenger conveyors; Promptly the abnormity notifying portion 33 through Long-Range Surveillance Unit 30 will be about the information that unusual this situation takes place and the information of unusual scene; Notify surveillant with modes such as image or sound, send the maintenance inspection plan of service personnel etc. with formulation to central monitoring position.
Communication line switching part 60 is located at control setup 20 sides of communication line 40, will be from the control setup 2 of this scene side
0 be sent out per 1 the week the collection quantitative data input beyond Long-Range Surveillance Unit 30.That is, communication line switching part 60 constitutes and can communication line temporarily be switched to portable monitor unit 70 sides from Long-Range Surveillance Unit 30 sides.
Communication line switching part 60; After Long-Range Surveillance Unit 30 detects the unusual of monitored object passenger conveyors and notifies the surveillant; Send service personnel to the scene; After checking upkeep operation at the scene and repairing, and the maintenance inspection result's who is obtained by side at the scene data maintenance personnel are switched.Through this blocked operation, communication line temporarily switches to portable monitor unit 70 from Long-Range Surveillance Unit 30, portable monitor unit 70 carry out with the equal diagnosis of Long-Range Surveillance Unit 30 as simple diagnosis.
Here, control setup 20 be provided with the place in the Machine Room, top 2 with Machine Room, bottom 3 such carry out easily wired connection local time, select to use wired portion 77 that receives and sends messages of portable monitor unit 70.On the other side, control setup 20 be provided with the place in the optional position of truss 1 wired connection select to use wireless receiving and dispatching information portion 77 at need.
In said structure; Starting operation or finish to run etc. in the time period that the people is few, ambient noise is few the running sound of the passenger conveyors that control setup 20 input portable collection mixer 10c and fixed type collection mixer 10a, 10b collect at the facility that is provided with the monitored object passenger conveyors.Then, this running sound is as the voice data that can send, based on the detection signal of reference position through sensor 50, by several weeks of keeping in week.Further, these each all collection data by keeping are sent to Long-Range Surveillance Unit 30 through communication line 40.
Long-Range Surveillance Unit 30 is accepted the voice data that sends over from the control setup 20 of on-the-spot side through communication line 40.Then, through the unusual judging part 35 of data processing division 32, compared to determine the voice datas just often of several weeks no abnormal by the voice data that receives in week and the passenger conveyors of trying to achieve in advance.
In case detect the unusual of monitored object passenger conveyors among this abnormality diagnostic result, promptly after notifying the surveillant, send service personnel to the scene.Service personnel is checked upkeep operation and repairing to the monitored object passenger conveyors at the scene.After this operation, under the situation that operation is accomplished, on-the-spot service personnel need obtain and be used to confirm the unusual data of having eliminated.
As this unusual confirmation method of eliminating; The running sound that consideration will collect the passenger conveyors of mixer 10c, 10a, 10b collection once more sends to Long-Range Surveillance Unit 30; Analyze passenger conveyors running sound at this Long-Range Surveillance Unit 30, and the result is sent to service personnel.
But, be PHS circuit etc. at communication line 40, under the lower situation of speed of transmission, the time of delivering letters of passenger conveyors running sound needs more than the dozens of minutes.Therefore, operation during this period can't stop, and service personnel can't be rushed towards the next scene of safeguarding, produces unnecessary waiting time.
In this embodiment, when side was obtained maintenance inspection result's data at the scene, the operation through service personnel switched to portable monitor unit 70 sides with communication line switching part 60.Through this blocked operation, communication line switches to portable monitor unit 70 sides from Long-Range Surveillance Unit 30 sides, and therefore, the running sound of the passenger conveyors that collection mixer 10c, 10a, 10b collect after the maintenance inspection operation is input to portable monitor unit 70.Portable monitor unit 70 has the diagnosis function identical with Long-Range Surveillance Unit 30, and after the maintenance inspection operation, the running sound of the passenger conveyors that collection mixer 10c, 10a, 10b are collected relatively has N/R simple diagnosis with voice data just often.The result of this simple diagnosis, in case confirm not have unusually after the maintenance inspection operation, being about to this affirmation does not have unusual data to be kept in the portable monitor unit 70, and stops maintenance inspection or repair work.
Like this, do not have unusual affirmation to be undertaken after the maintenance inspection operation, therefore do not have unusual data to obtain at short notice then and there by the portable monitor unit 70 of side at the scene.Therefore, under the communication line 40 low-tach situation, need not spend the above time of delivering letters of dozens of minutes, send to Long-Range Surveillance Unit 30, therefore can carry out the diagnosis after maintenance inspection and the repair work effectively what passenger conveyors turned round sound.
Service personnel is confirmed after the normal recovery of passenger conveyors at the scene, and communication line switching part 60 is switched to Long-Range Surveillance Unit 30 sides, makes communication line 40 return normal coupled condition, simultaneously Long-Range Surveillance Unit 30 is sent diagnosis requirement arbitrarily.Like this, Long-Range Surveillance Unit 30 basic data of carrying out behind the condition improvement of passenger conveyors is collected.
Again, in this embodiment, communication switching part 60 constitutes the switching that manually communicates circuit, but also can constitute after the switching through automatically being connected to communication line 40 after the predefined time.Like this, can avoid forgetting the connection recovery of communication line 40.
As above; In the diagnostic device of the passenger conveyors of this embodiment; To after the maintenance inspection of monitored object passenger conveyors and repairing, collection mixer 10a, 10b, 10c collect passenger conveyors running sound to service personnel in the roughly whole stroke of passenger conveyors at the scene.Then, this collection mixer 10a, 10b, the collected passenger conveyors running sound of 10c are provided with on-the-spot control setup 20 by passenger conveyors and convert voice data into.This voice data is not sent to the Long-Range Surveillance Unit 30 that is arranged on central monitoring position remotely through communication line 40, but is sent to portable monitor unit 70.Portable monitor unit 70; The voice data (supervision voice data) of this passenger conveyors running sound is compared with the voice data just often that is just often obtained in advance; Carry out unusual simple and easy judgement, and will have the information untill further notice of no abnormal scene to give portable monitor unit 70.
