What control setup 20 and position detecting device 50 were arranged on monitored object passenger conveyors arranges the outside anywhere of pedal 4 in scene.Again, position detecting device 50 passes through sensor as reference position described later.Long-Range Surveillance Unit 30 is positioned at and arranges scene remotely away from monitored object passenger conveyors, is arranged on the central monitoring position connected by communication line 40.Communication line shifter 60 and portable monitor device 70 are arranged on the on-the-spot side of communication line 40.
Be arranged on check the portable audio collecting device 10c of pedal 5 when monitored object passenger conveyors operate along with check pedal 5 together loopy moving to collect the operation noise of passenger conveyors.Again, as fixed type audio collecting device, be namely arranged on the audio collecting device 10a of Machine Room, top 2 and be arranged on the audio collecting device 10b of lower mechanical room 3, collecting the operation noise of the passenger conveyors near Machine Room, top 2 and lower mechanical room 3 with portable audio collecting device 10c simultaneously.
This portable audio collecting device 10c and fixed type audio collecting device 10a, 10b as shown in Figure 2, have: convert tones into the collection line 11 that aud. snl. exports; The aud. snl. that collection line 11 exports is converted to the wireless receiving and dispatching information portion 12 that wireless signal sends; Collection line 11 and wireless receiving and dispatching information portion 12 are provided to the power suppling part 13 of power supply.In the audio collecting device 10c (10a, 10b are too) formed like this, when passenger conveyors operates, once power suppling part 13 provides power supply to collection line 11 and wireless receiving and dispatching information portion 12, the operation noise being about to occur along with the running of passenger conveyors is converted to aud. snl. by collecting line 11, and this aud. snl. is converted into wireless signal by wireless receiving and dispatching information portion 12 and sends.
Here, portable audio collecting device 10c is loopy moving together with inspection pedal 5, and the passenger conveyors operation noise collected by each place on the mobile route of pedal 4 is sent out as wireless signal.The wireless signal be sent out from this portable audio collecting device 10c is received by control setup 20.Same, be arranged on the fixed type audio collecting device 10a of Machine Room, top 2, the operation noise of the winch that the figure near collection Machine Room, top 2 does not show and sprocket wheel etc., and collect multiple pedal 4 by operation noise during Machine Room 2, top.Again, be arranged on the fixed type audio collecting device 10b of lower mechanical room 3, the operation noise of the sprocket wheel that the figure near collection lower mechanical room 3 does not show etc., and collect multiple pedal 4 by operation noise during lower mechanical room 3.
Again, although Fig. 1 illustrates that portable audio collecting device 10c is only arranged on the example that checks pedal 5, audio collecting device 10c also can be arranged on plural inspection pedal 5.
Here, on passenger conveyors, set reference position, this reference position place is provided with position detecting device 50.This reference position conduct, for determining the reference position of the reference position of the abnormal sound scene detected by portable audio collecting device 10c and the collection sound timing synchronization for collection sound moment and portable audio collecting device 10c of making fixed type audio collecting device 10a, 10b.This reference position is arranged on the assigned position on the loopy moving path of pedal band, and the position detecting device 50 being arranged on this reference position detects and checks the moment of pedal 5 by this reference position.Therefore, this position detecting device 50 is called that sensor is passed through in reference position below.
Like this, the reference position that reference position is specified by sensor 50 in the inspection pedal 5 being arranged at portable audio collecting device 10c is by this mobile route (such as, the horizontal part etc. of lower floor as shown in Figure 1) moment, to control setup 20 outgoing position detection signal.This reference position by the formation of sensor 50 is, such as, by arranging proximity transducer and opto-electronic pickup etc. in reference position, is checking in pedal 5 metal sheet etc. installed for identifying this inspection pedal 5.Then, be arranged on the proximity transducer of reference position and opto-electronic pickup etc. and detect passing through of the inspection pedal 5 of metal sheet is installed, and at this by moment outgoing position detection signal.
Again, adopt proximity transducer and opto-electronic pickup as the situation of reference position by sensor 50 although illustrate to have, as an alternative, also inclination sensor can be set in inspection pedal 5.Now, reference position is the place from the horizontal part of lower floor to rake movement.That is, when checking that pedal 5 moves to rake from the horizontal part of lower floor, the rolling mechanism that the figure of pedal 5 does not show moves to heeling condition from horizontality, therefore, using the mobile moment to this angle of inclination as the moment by reference position.
The control setup 20 of on-the-spot side, using as each audio collecting device 10c of data collection module and the collection phenomenon of 10a, 10b and the operation noise of passenger conveyors, be converted to the voice data that can send, and carry out keeping in each week of passenger conveyors (running) as collection data.Namely, based on the detection signal of reference position by sensor 50, from inspection pedal 5 by reference position to carrying out keeping by each week the moment of reference position next time, this is sent to the object of delivering letters of regulation by communication line by the collection data in each week of taking care of.Namely, this control setup 20 receives by portable audio collecting device 10c and fixed type audio collecting device 10a, 10b collection sound, the passenger conveyors operation noise that is sent out as wireless signal, be converted into voice data again, and by the voice data of this passenger conveyors operation noise, such as, the Long-Range Surveillance Unit 30 as the central monitoring position of object of delivering letters is sent to by the communication lines such as telephone line 40.
Control setup 20, such as shown in Figure 2, comprising: wireless receiving and dispatching information portion 21, signal conversion part 22, memory device 23, data transmit-receive portion 24.The wireless signal that the wireless receiving and dispatching information portion 12 that wireless receiving and dispatching information portion 21 receives portable audio collecting device 10c (fixed type audio collecting device 10a, 10b are also identical) sends.The wireless signal that wireless receiving and dispatching information portion 21 receives is converted to voice data by signal conversion part 22.The voice data as prescribed cycle (such as one week) of the passenger conveyors operation noise that signal conversion part 22 is changed by memory device 23 carries out temporary storage.Data transmit-receive portion 24, sends the voice data of the passenger conveyors operation noise be temporarily stored in memory device 23 by communication line 40.
In the control setup 20 of such formation, be sent out as wireless signal once the passenger conveyors operation noise collected by passenger conveyors action audio collecting device 10a, 10b, 10c from each audio collecting device 10a, 10b, 10c, namely this wireless signal is received by wireless receiving and dispatching information portion 21, is converted into voice data and is stored in memory device 23 by signal conversion part 22.Then, the voice data being stored in the passenger conveyors operation noise of memory device 23 reads with the data unit of regulation, and is sent to the Long-Range Surveillance Unit 30 of the central monitoring position be arranged on remotely by communication line 40 from data transmit-receive portion 24.
Herein, portable audio collecting device 10c with check pedal 5 together loopy moving in each site collection passenger conveyors operation noise in the mobile route checking pedal 5, therefore, check that the passenger conveyors operation noise that pedal 5 rounds collected is stored in memory device 23 as voice data successively, the roughly omnidistance operation noise of such passenger conveyors is stored in memory device 23 as voice data, and can send it to Long-Range Surveillance Unit 30.
Again, for control setup 20, foregoing, check pedal 5 at every turn by reference position, namely provide position detection signal from reference position by sensor 50.Like this, control setup 20 can using from checking that pedal 5 is stored in memory device 23 as a data cell by reference position voice data of passenger conveyors operation noise of such a week to returning to this reference position again.Again, the voice data of the passenger conveyors operation noise of the data cell in each week can read from memory device 23 and be sent to Long-Range Surveillance Unit 30.
Similarly, the audio collecting device 10a being arranged on Machine Room, the top 2 and audio collecting device 10b being arranged on lower mechanical room also collects sound with portable audio collecting device 10c simultaneously, therefore, from checking that pedal 5 can be used as a data cell by reference position voice data of passenger conveyors operation noise of such a week to returning to this reference position and is stored in memory device 23.Again, the voice data of the operation noise of the passenger conveyors of each weekly data unit can from memory device 23 reading and sending to Long-Range Surveillance Unit 30.
Long-Range Surveillance Unit 30 comprises: be connected to communication line 40, receive the collection data that the control setup 20 from on-the-spot side sends over, collection data time normal to the collection data in each week received and the passenger conveyors of trying to achieve in advance are compared, is determined with N/R abnormality determination unit.Namely, this Long-Range Surveillance Unit 30 receives the voice data of the passenger conveyors operation noise sended over via communication line 40 arranging on-the-spot control setup 20 from passenger conveyors, carries out the process of the exception for detecting monitored object passenger conveyors based on this voice data.
This Long-Range Surveillance Unit 30, such as shown in Figure 2, has data transmit-receive portion 31, data processing division 32 and abnormal notification unit 33.Data transmit-receive portion 31 is connected with communication line 40, the voice data of the passenger conveyors operation noise that the data transmit-receive portion 24 receiving self-control device 20 obtains via communication line 40 messenger.Data processing division 32, carries out the voice data of the passenger conveyors operation noise that data receiving and transmitting part 31 receives analyzing the exception detecting monitored object passenger conveyors and occur.The data results of data processing division 32 is informed to the surveillant of central monitoring position by abnormal notification unit 33 by image or sound etc.Further, the inside of data processing division 32 is provided with the memory device 34 storing various data and the abnormality determination unit 35 of carrying out abnormality juding.
Be arranged at the internal storage 34 of the data processing division 32 of Long-Range Surveillance Unit 30, there is following the 1st, the 2nd, the 3rd and the 4th illustrated data area.In 1st data area, for each monitored object passenger conveyors, store " on-the-spot place and the liaison method of passenger " that these passenger conveyors are set etc.In 2nd data area, for each monitored object passenger conveyors, store " specification data that passenger conveyors is intrinsic " of respective story height or trip distance, angle of inclination, operating speed, rotation direction etc.In 3rd data area, store monitored object passenger conveyors normal time adopt audio collecting device 10a, 10b, 10c to obtain in advance " time normal voice data ".When the passenger conveyors such as monitored object is registered, collect these data, and write each self-corresponding region.
Again, once the voice data of the passenger conveyors operation noise sended 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, by the voice data of this passenger conveyors operation noise, to check each of data unit measured for a week that pedal 5 was collected by audio collecting device 10a, 10b, 10c during a week, temporarily be stored in the 4th data area of internal storage 34, i.e. the data area of " supervision voice data ".
The abnormality determination unit 35 of data processing division 32 inside, by the voice data being sent to the passenger conveyors operation noise of Long-Range Surveillance Unit 30 from control setup 20 via communication line 40 collected by audio collecting device 10a, 10b, 10c and monitored object passenger conveyors normal time adopt audio collecting device 10a, 10b, 10c obtain in advance normal time voice data compare, judge whether monitored object passenger conveyors exception occurs.
Namely, abnormality determination unit 35 reads " time normal the voice data " of the 3rd data area being stored in advance in memory device 34 respectively, these voice datas are input in comparator and compare by " the supervision voice data " of the 4th data area of write store 34 at any time.Here, " supervision voice data " and " time normal voice data " read-out by memory device 34 is respectively, using the inspection pedal 5 being provided with audio collecting device 10c by moment of reference position as starting position, the time series data of audio collecting device 10a in the time that this pedal 5 runs one week, passenger conveyors operation noise collected by 10b, 10c.Abnormality determination unit 35 makes these " supervision voice datas " consistent with the respective starting position of " time normal voice data " and is input to comparator, such as, between " supervision voice data " and " time normal voice data ", when the part of difference of sound press level of the abnormality juding threshold value exceeding regulation being detected, judge that monitored object passenger conveyors produces abnormal.
Again, abnormality determination unit 35 is when judging that monitored object passenger conveyors produces abnormal, and reading pre-stored is in " specification data that passenger conveyors is intrinsic " of the 2nd data area of memory device 34.Then based on the comparative result of " supervision voice data " and " time normal voice data ", and " specification data that passenger conveyors is intrinsic " that read from memory device 34, determine abnormal scene.
Specifically, when the reference position corresponding with the starting position of voice data be the horizontal part of lower floor, the rotation direction of passenger conveyors operates for rising, operating speed be 30m/ divide, be formed as length be 8m time, if be judged to be that the time T of abnormal part is 20 seconds from data start position, by supervision voice data, then determine to check that pedal 5 is in the position of the horizontal part advance 10m from lower floor, that is, occur near the Machine Room of the upper layer side after turning back in upper strata abnormal.Again, because the trip distance of passenger conveyors can calculate according to the story height of passenger conveyors and angle of inclination geom, therefore, when the trip distance not storing passenger conveyors is as specification data, the data at story height and angle of inclination also can be adopted to determine abnormal scene.
As mentioned above, once judge that monitored object passenger conveyors occurs abnormal and determines this abnormal scene by abnormality determination unit 35, namely by the abnormal notification unit 33 of Long-Range Surveillance Unit 30 by about the abnormal information of this situation of generation and the information of abnormal scene, the surveillant of central monitoring position is informed, to formulate the maintenance inspection plan of sending service personnel etc. in the mode such as image or sound.
Communication line switching part 60 is located at control setup 20 side of communication line 40, and the collection data of every 1 week be sent out by the control setup 20 from this on-the-spot side are input to beyond Long-Range Surveillance Unit 30.That is, communication line switching part 60 is configured to communication line to be temporarily switched to portable monitor device 70 side from Long-Range Surveillance Unit 30 side.
Portable monitor device 70 has abnormality determination unit, this abnormality determination unit have the passenger conveyors of trying to achieve in advance normal time collection data, by compare this normal time collection data and from communication line switching part 60 input collection data, determine whether exception.Namely, portable monitor device 70 as shown in Figure 3, formed with the functional module roughly the same with Long-Range Surveillance Unit 30, be there is data transmit-receive portion 71, data processing division 72, abnormal notification unit 73, the memory device 74 of data processing division, abnormality determination unit 75 and operation inputting part 76 respectively.These functions are roughly the same with the corresponding function module of Long-Range Surveillance Unit 30.Data transmit-receive portion 71 is configured to can any switching laws wireless receiving and dispatching information portion 77 and wired portion 78 that receives and sends messages.
Communication line switching part 60, Long-Range Surveillance Unit 30 detect monitored object passenger conveyors exception and after notifying surveillant, send service personnel to scene, after carrying out Inspection and maintenance operation at the scene and repairing, and by should side obtains at the scene the data maintenance personnel of maintenance inspection result switch.By this blocked operation, communication line is temporarily switched to portable monitor device 70 from Long-Range Surveillance Unit 30, and portable monitor device 70 carries out the diagnosis equal with Long-Range Surveillance Unit 30 as simple diagnosis.
Herein, the set-up site of control setup 20 Machine Room, top 2 and lower mechanical room 3 such easily carry out wired connection local time, wired portion 77 that receives and sends messages of choice for use portable monitor device 70.On the other side, the set-up site of control setup 20 truss 1 optional position wired connection at need, choice for use wireless receiving and dispatching information portion 77.
In said structure, being provided with the starting operation or terminate in the time periods that people is few, ambient noise is few such as operation of facility of monitored object passenger conveyors, control setup 20 inputs the operation noise of the passenger conveyors that portable audio collecting device 10c and fixed type audio collecting device 10a, 10b collect.Then, this operation noise, as the voice data that can send, based on the detection signal of reference position by sensor 50, takes care of a few week by week.Further, this is sent to Long-Range Surveillance Unit 30 by the collection data in each week of taking care of by communication line 40.
Long-Range Surveillance Unit 30 accepts the voice data sended over from the control setup 20 of on-the-spot side by communication line 40.Then, by the abnormality determiner 35 of data processing division 32, several weeks have been compared to determine without exception by the voice data during voice data received in week and the passenger conveyors of to try to achieve in advance normal.
Once the exception of monitored object passenger conveyors be detected in this abnormality diagnostic result, namely after notifying surveillant, send service personnel to scene.Service personnel carries out Inspection and maintenance operation and repairing to monitored object passenger conveyors at the scene.After this operation, when operation completes, on-the-spot service personnel needs to obtain for confirming the abnormal data eliminated.
As this abnormal confirmation method eliminated, consider that the operation noise of the passenger conveyors again audio collecting device 10c, 10a, 10b collected is sent to Long-Range Surveillance Unit 30, analyze passenger conveyors operation noise at this Long-Range Surveillance Unit 30, and result is sent to service personnel.
But be PHS circuit etc. at communication line 40, when speed of transmission is lower, the time of delivering letters of passenger conveyors operation noise needs more than dozens of minutes.Therefore, operation during this period cannot stop, and it is on-the-spot that service personnel cannot rush towards next maintenance, produces unnecessary wait time.
In this embodiment, when side obtains the data of maintenance inspection result at the scene, by the operation of service personnel, communication line switching part 60 is switched to portable monitor device 70 side.By this blocked operation, communication line is switched to portable monitor device 70 side from Long-Range Surveillance Unit 30 side, and therefore, after maintenance inspection operation, the operation noise of the passenger conveyors that audio collecting device 10c, 10a, 10b collect is input to portable monitor device 70.Portable monitor device 70 has the diagnosis function identical with Long-Range Surveillance Unit 30, and after maintenance inspection operation, the operation noise of the passenger conveyors collected by audio collecting device 10c, 10a, 10b compares with voice data time normal carries out there is N/R simple diagnosis.The result of this simple diagnosis, once not abnormal after confirming maintenance inspection operation, do not have abnormal data to be kept in portable monitor device 70 by this confirmation, and stops maintenance inspection or repair work.
Like this, do not have abnormal confirmation to be undertaken by the portable monitor device 70 of side at the scene after maintenance inspection operation, so there is no abnormal data can obtain then and there at short notice.Therefore, when communication line 40 low speed, do not need to spend the time of delivering letters more than dozens of minutes, passenger conveyors operation noise is sent to Long-Range Surveillance Unit 30, therefore effectively can carry out the diagnosis after maintenance inspection and repair work.
After service personnel confirms the normal recovery of passenger conveyors at the scene, communication line switching part 60 switched to Long-Range Surveillance Unit 30 side, make communication line 40 return normal coupled condition, Long-Range Surveillance Unit 30 is sent simultaneously and diagnose requirement arbitrarily.Like this, the basic data after Long-Range Surveillance Unit 30 carries out the condition improvement of passenger conveyors is collected.
Again, in the present embodiment, communication switching part 60 is configured to the switching manually carrying out communication line, but after the time preset, is automatically connected to communication line 40 after also can being configured to switching.Like this, the connection forgetting communication line 40 can be avoided to recover.
