The specific embodiment
Below, with reference to accompanying drawing implementation form of the present invention is described in detail.In the example below, as an example of passenger conveying appliance, exemplify a plurality of steps and step up the escalator that lower floor ground tilts to move.Yet certainly, when mobile moving sidewalk was as diagnosis object in the horizontal direction continuously take a plurality of steps (pedal), the present invention also can use effectively.
(the first example)
At the abnormity diagnostic system of the first example of the present invention shown in Figure 1, supported this truss 3 and upper layer part beam 1 and 2 links of lower layer part beam and be erected between the levels by truss 3 as the escalator of diagnosis object.In the truss 3 of upper layer part beam 1 side, be provided with the actuating device 4 of escalator.Actuating device 4 carries out action control by control desk 5, drives by 6 pairs of drive sprockets 7 of chain drive-belt.And, in the truss 3 of lower layer part beam 2 sides, be provided with in couples driven sprocket 8 with drive sprocket 7.Step chain 9 is wrapped between drive sprocket 7 and the driven sprocket 8, and a plurality of steps 10 link with step chain 9.Actuating device 4 makes drive sprocket 7 rotations, thereby step chain 9 is rotated around between drive sprocket 7 and the driven sprocket 8.As a result, a plurality of steps 10 are along not shown guide rail loopy moving between the stopping port of upper layer side and lower layer side stopping port.
And, by the guardrail 13 that wrapper plate 11 and guardrail board 12 form, the vertical left and right sides that is located at the step 10 of loopy moving.Handrail 14 is installed in the periphery of guardrail board 12.Handrail 14 is to take the handrail that the passenger on step 10 controls, and by being passed for example propulsive effort of above-mentioned actuating device 4, synchronously rotates around guardrail board 12 with the movement of step 10.And operating panel 15 is arranged on the wrapper plate 11 of the upper and lower.Operating panel 15 is provided with various operating switchs 16, be used for the supvr of escalator and maintenance staff's operation, comprise run switch be used to the start/stop of carrying out escalator, be used for when start/stop operate, making alarm switch that the annunciator ring moves etc.The various operating switchs 16 that are located on the operating panel 15 are connected with control desk 5.
In the escalator that as above consists of, can carry out for the diagnosis that makes the abnormity diagnostic system that adopts the first example, make some at least as checking step 10A in a plurality of steps 10 of loopy moving.Mobile set mixer 17a is arranged on the inside that checks step 10A, on one side with checking step 10A loopy moving, collects escalator running sound on one side.And fixed set mixer 17b, 17c that fixed point is collected escalator running sound are arranged on such as on the lower layer side of truss 3 and the upper layer side etc.By the collected escalator running sound of mobile set mixer 17a, be input in the monitor unit 20 as wireless signal.By the collected escalator running sound of fixed set mixer 17b, 17c, be input in the monitor unit 20 as wire signal or wireless signal.In the following description, except the situation of special difference mobile set mixer 17a and fixed set mixer 17b, 17c, they are generically and collectively referred to as collection mixer 17.
Long-Range Surveillance Unit 30 receives the aud. snl. of the escalator running sound that sends via communication network CN from monitor unit 20, resolves by the aud. snl. to the escalator running sound that receives, comes unusually diagnosing escalator.Specifically, Long-Range Surveillance Unit 30, for example, in advance the voice data of collected escalator running sound when normal when the escalator no exceptions is stored, the voice data of voice data by the escalator running sound that will send from monitor unit 20 when normal compares, the abnormal sound composition is extracted out, according to the feature of this abnormal sound composition etc. to unusually diagnosing.These monitor units 20 and Long-Range Surveillance Unit 30 consist of apparatus for diagnosis of abnormality.
In the first example, the voice data of 30 transmission escalator running sounds is resolved and then unusually diagnosing escalator this voice data on Long-Range Surveillance Unit 30 from monitor unit 20 to Long-Range Surveillance Unit.Yet, also can be on monitor unit 20 resolve and then carry out the abnormity diagnosis of escalator to the voice data of escalator running sound, this diagnostic result is sent to Long-Range Surveillance Unit 30.
Here, the details of the monitor unit 20 of the abnormity diagnostic system of the first example carried out more specific description.
As shown in Figure 2, monitor unit 20 comprises: be used for carrying out the CPU21 that data are processed; The memory device 22 that the voice data of escalator running sound is stored; Carried out the collection sound time timing time meter 23 of timing the collection sound time of escalator running sound; Be used for from interface (I/F) 24a, 24b, the 24c of the voice data of mobile set mixer 17a and fixed set mixer 17b, 17c input escalator running sound.
CPU21 monitors the run signal from the escalator of control desk 5.When being intended to make the run signal of escalator startup from control desk 5 outputs, CPU21 just makes collection sound time timing with time meter 23 startings, makes simultaneously at least certain collection mixer 17 startup among mobile set mixer 17a and fixed set mixer 17b, the 17c.Then, the collection mixer 17 that has started is collected escalator running sound, by interface 24a-24c this voice data is inputted CPU21.Then, CPU21 stores the voice data of the escalator inputted running sound in the memory device 22 into.
At this moment, when the voice data of the escalator running sound of storing in memory device 22 for the back sends to Long-Range Surveillance Unit 30, what kind of data can identify these data at Long-Range Surveillance Unit 30 is, CPU21 will represent that the running state data of escalator operation state etc. and the voice data of escalator running sound store in the memory device 22 together.Here, the running state data of so-called escalator refers to, is used for the escalator recognition data that expression is the running sound of which escalator; Be used for expression and be the collection mixer recognition data by the collected escalators running sound of which collection mixer 17; Also have in addition, the running state of the escalator during the collection sound is rise operation or decline operation, if carry out the escalator that running velocity switches, is the data such as high-speed cruising or low cruise.
Then, to collection sound time timing with during till the timing of 23 end setup times of time meter, CPU21 stores the voice data of the escalator running sound inputted in the memory device 22 at any time.In the stage of collection sound time timing with the timing of 23 end setup times of time meter, CPU21 stops the collection of the escalator running sound that is undertaken by collection mixer 17, finishes voice data to the storage of memory device 22.Here, above just passable around the time that mobile circulating path rotates a week as long as will collect the timing of sound time is set as escalator with the setting-up time of time meter 23 step 10.
In the first example, the voice data of the escalators running sound that collection mixer 17 is collected is inputted monitor unit 20 at any time, stores at any time in the memory device 22 of monitor unit 20 inside.Yet, also can be provided at collection mixer 17 memory device of the abundant capacity of stored sound data, during collection mixer 17 is collected escalator running sound, this voice data is stored in the memory device of collection mixer 17, after the collection of the escalator running sound that is undertaken by collection mixer 17 finishes, with the voice data input monitor unit 20 of this escalator running sound, store in the memory device 22 of inside of monitor unit 20.
As top enumerate concrete example the explanation at length carried out, adopt the abnormity diagnostic system of the first example, within the specified time after the fewer escalator of interference tones beyond the predicted escalator running sound has just started, make collection mixer 17 collect escalator running sound, and this voice data is stored in the memory device 22 of monitor unit 20.Therefore, in the abnormity diagnostic system of the first example, when adopting the voice data of this escalator running sound to carry out the abnormity diagnosis of escalator, can suppress the adverse effect brought to diagnosis by interference tones as far as possible, carry out accurately the abnormity diagnosis of escalator.
(the second example)
Below, the second example of the present invention is described.The abnormity diagnostic system of the second example, it is different from above-mentioned the first example that its collection mixer 17 is collected the moment of escalator running sound.That is, in the first example, collect escalator running sound within the specified time of collection mixer 17 after escalator just starts.Yet, in the second example, starting at escalator and to start collection mixer 17 after beginning through the standby time of regulation, collection mixer 17 is collected the escalator sound that turns round within specified time thereafter.
After escalator has just started, the supvr that the operating switch 16 of operating panel 15 is operated and staff are near escalator, therefore its footsteps becomes interference tones, and cross in the situation such as low in ambient temperature, the equipment each several part of escalator needed some times before reaching regular event.Therefore, also exist before this during in the sound that sends become interference tones, interference tones surpasses the situation of datum-plane.Therefore, in the abnormity diagnostic system of the second example, start from escalator within the specified time of beginning, make collection mixer 17 not collect escalator running sound and standby, through beginning again after the standby time by the turn round collection of sound of the escalator that collection mixer 17 carries out.
As shown in Figure 3, in the second example, in the inside of monitor unit 20, except the illustrated CPU21 of the first example, memory device 22, collection sound time timing with also having added standby time timing usefulness time meter 25 time meter 23 and the interface 24a-24c.
CPU21 monitors the run signal from the escalator of control desk 5.When being intended to make the run signal of escalator startup from control desk 5 outputs, CPU21 at first makes the standby time timing start with time meter 25.Then, when the timing of 25 end setup times of time meter was used in the standby time timing, CPU21 made collection sound time timing with time meter 23 startings, makes simultaneously at least certain collection mixer 17 startup among mobile set mixer 17a and fixed set mixer 17b, the 17c.The collection mixer 17 that has started is by the voice data input CPU21 of interface 24a-24c with collected escalator running sound.Then, CPU21 stores this voice data in the memory device 22 into.Here, wait by experiment in advance, the required time measured till the equipment each several part of escalator reached regular event during to low temperature, and this is just passable more than time as long as the standby time timing is set to the setting-up time of time meter 25.
Then, identical with the first example, to collection sound time timing with during till the timing of 23 end setup times of time meter, CPU21 stores the voice data of the escalator running sound inputted in the memory device 22 at any time.Be through with stage of timing of setting-up time with time meter 23 in collection sound time timing, CPU21 stops the collection of the escalator running sound that is undertaken by collection mixer 17, and the end voice data is to the storage of memory device 22.
As mentioned above, adopt the abnormity diagnostic system of the second example, begin through within the specified time after the standby time of regulation from starting escalator, make collection mixer 17 collect escalator running sound, and this voice data is stored in the memory device 22 of monitor unit 20.Therefore, in the abnormity diagnostic system of the second example, the improper situation of issuable interference tones after can preventing from collecting mixer 17 and collecting escalators and just started prevents the adverse effect brought to diagnosis by interference tones more reliably, carries out more accurately the abnormity diagnosis of escalator.
(the 3rd example)
Below, the 3rd example of the present invention is described.The abnormity diagnostic system of the 3rd example, it is different from above-mentioned first, second example that its collection mixer 17 is collected the moment of escalator running sound.That is, in first, second example, collection mixer 17 is implemented the collection of escalator running sound when escalator starts.Yet in the 3rd example, collection mixer 17 is implemented the collection of escalator running sound when escalator stops.
Be arranged at the escalator as diagnosis object in the situation in the facility such as shop, facility winding-up and closing the door when escalator is stopped, not having the user around the escalator, and environment is quiet mostly.Therefore, interference tones is fewer, can think that interference tones is below datum-plane.Therefore, in the abnormity diagnostic system of the 3rd example, when having the operation that escalator is stopped to input, make collection mixer 17 within specific time, collect escalator running sound, then, the operation of escalator is stopped.
As shown in Figure 4, in the 3rd example, the CPU21 of the inside of the halt instruction input monitor unit 20 of the escalator that is produced by the operation of operating switch 16.CPU21 can export the control command that stops for the operation that makes escalator to control desk 5.
The halt instruction input CPU21 of the escalator that is produced by the operation of operating switch 16.So CPU21 makes collection sound time timing with time meter 23 startings, and at least certain the collection mixer 17 among mobile set mixer 17a and fixed set mixer 17b, the 17c is started.Then, the collection mixer 17 that has started is by the voice data input CPU21 of interface 24a-24c with collected escalator running sound.Then, CPU21 stores this voice data in the memory device 22 into.
Then, identical with the first example, to collection sound time timing with during till the timing of 23 end setup times of time meter, CPU21 stores the voice data of the escalator running sound inputted in the memory device 22 at any time.Then, be through with stage of timing of setting-up time with time meter 23 in collection sound time timing, CPU21 stops the collection of the escalator running sound that is undertaken by collection mixer 17, and the end voice data is to the storage of memory device 22.Then, CPU21 for the control command that the operation that makes escalator stops, stopping the operation of escalator to control desk 5 outputs.
As mentioned above, adopt the abnormity diagnostic system of the 3rd example, within the specified time before the fewer escalator of interference tones beyond predicted escalator running sound stops, make collection mixer 17 collect escalator running sound, and this voice data is stored in the memory device 22 of monitor unit 20.Therefore, in the abnormity diagnostic system of the 3rd example, when adopting the voice data of this escalator running sound to carry out the abnormity diagnosis of escalator, can suppress the adverse effect brought to diagnosis by interference tones as far as possible, carry out accurately the abnormity diagnosis of escalator.
(the 4th example)
Below, the 4th example of the present invention is described.The abnormity diagnostic system of the 4th example is escalator take the automatic operation scheme of the what is called example during as diagnosis object.The escalator of automatic operation scheme, that normally stop or carry out low speed standby operation, approach within the beginning at the appointed time with the conventional speeds operation from detecting the passenger, to compare electric power consumption little with general escalator, and the state that therefore sometimes keeps starting in 24 hours is employed.Therefore, be difficult to collect escalator running sound when escalator starts and when stopping, being necessary in escalator starts some constantly, escalator running sound is collected.
Here, as above narrate, automatically the escalator of operation scheme is detecting before the passenger approaches, be stop or carry out low speed standby operation.In other words, stop or carrying out low speed standby run duration at the automatic escalator of operation scheme, do not have the user on every side.Therefore, stop or carrying out low speed standby run duration at the automatic escalator of operation scheme, interference tones is fewer, can think that interference tones is below datum-plane.Therefore, in the abnormity diagnostic system of the 4th example, when the escalator of automatic operation scheme stops or carrying out low speed standby operation, start collection mixer 17, simultaneously escalator is switched to the conventional operation state.Then, within specified time thereafter, the 17 pairs of escalators of collection mixer running sound is collected, and in the stage after the collection of the escalator running sound that is undertaken by collection mixer 17 finishes, escalator returned to stops or low speed standby running state.
As shown in Figure 5, in the 4th example, occupant detection sensor 18 is connected with control desk 15 with the running timer of being connected 19, and the automatic operation of 5 pairs of escalators of control desk is controlled.That is, control desk 5 makes escalator keep stopping or low speed standby running state usually.When detecting the passenger near escalator by occupant detection sensor 18, control desk 5 switches to operation under the conventional speeds with the operation of escalator, makes simultaneously automatic running timer 19 startings.Then, be through with stage of timing of setting-up time at automatic running timer 19, control desk 5 returns to escalator to stop or low speed standby running state.
Automatically moved the running state of the escalator of control by this control desk 5, can confirm by the run signal of exporting from control desk 5, in the 4th example, from the run signal input monitor unit 20 of this control desk 5.And in the 4th example, the CPU21 of monitor unit 20 inside can export to control desk 5 operation of escalator being switched the control command of indicating.When the control command from the CPU21 of monitor unit 20 inside was output, control desk 5 switches the operation of escalator according to this control command to be controlled.
CPU21 monitors the running state of automatically being moved the escalator of control according to the run signal of exporting from control desk 5.When escalator stopped or carrying out low speed standby operation, CPU21 made collection sound time timing with time meter 23 startings, and at least certain the collection mixer 17 among mobile set mixer 17a and fixed set mixer 17b, the 17c is started.Then, the collection mixer 17 that has started is by the voice data input CPU21 of interface 24a-24c with collected escalator running sound.CPU21 stores this voice data in the memory device 22 into.And, when the collection of the escalator running sound that is undertaken by collection mixer 17 begins, CPU21 is used to indicate the control command that escalator is switched to the operation under the conventional speeds to control desk 5 outputs, between escalator is with the conventional speeds on-stream period, escalator running sound is collected in the collection mixer 17.
Then, to collection sound time timing with during till the timing of 23 end setup times of time meter, CPU21 stores the voice data of the escalator running sound inputted in the memory device 22 at any time.Then, be through with stage of timing of setting-up time with time meter 23 in collection sound time timing, CPU21 stops the collection of the escalator running sound that is undertaken by collection mixer 17, and the end voice data is to the storage of memory device 22.Then, CPU21 is used to indicate escalator switched to control desk 5 output and stops or the control command of low speed standby operation, escalator is returned to stop or low speed standby running state.
During carrying out the collection of escalator running sound by collection mixer 17, when occupant detection sensor 18 detect the passenger near the time, the collection of the escalator running sound that is undertaken by collection mixer 17 is stopped.When not having the passenger, as long as it is just passable again to carry out the collection of escalator running sound by collection mixer 17.Specifically, when detect by occupant detection sensor 18 passenger near the time, control desk 5 makes the timing of automatic running timer 19 begin to monitor unit 20 output occupant detection signals simultaneously.When from control desk 5 input occupant detection signal, the CPU21 of monitor unit 20 just makes the collection of the escalator running sound that is undertaken by collection mixer 17 stop, and will collect simultaneously the timing of sound time and reset with time meter 23.When automatic running timer is through with stage of timing of setting-up time, CPU21 makes collection sound time timing with time meter 23 startings again, starts simultaneously collection mixer 17, the collection of the escalator running sound that beginning is undertaken by collection mixer 17.
As mentioned above, adopt the abnormity diagnostic system of the 4th example, automatically the escalator of operation scheme be stop or carry out low speed standby operation.Estimating do not have user, the fewer moment of interference tones around the escalator, making collection mixer 17 collect escalator running sound, and this voice data is stored in the memory device 22 of monitor unit 20.Therefore, in the abnormity diagnostic system of the 4th example, when adopting the voice data of escalator running sound to carry out the abnormity diagnosis of escalator, can suppress the adverse effect brought to diagnosis by interference tones as far as possible, carry out accurately the abnormity diagnosis of escalator.
(the 5th example)
Below, the 5th example of the present invention is described.The abnormity diagnostic system of the 5th example, it is the example when the escalator as diagnosis object is provided with voice output for output guiding sound, during carrying out the collection of escalator running sound by collection mixer 17, controlling in order to make by the caused guiding sound of this voice output does not become interference tones.
As shown in Figure 6, in the 5th example, be provided with voice output 40 at the escalator as diagnosis object.This voice output 40 is connected with control desk 5 by contact 41, according to the voice output instruction from control desk 5, by loud speaker 42 the guiding sound such as destination guiding and notice guiding is exported repeatedly.
As mentioned above, adopt the abnormity diagnostic system of the 5th example, during carrying out the collection of escalator running sound by collection mixer 17, the output of the guiding sound that is undertaken by sound guiding device 40 is stopped.Therefore, in the abnormity diagnostic system of the 5th example, can effectively prevent from being become by sound guiding device 40 caused guiding sound the improper situation of interference tones, use accurately the abnormity diagnosis of escalator of the voice data of escalator running sound.
(the 6th example)
Below, the 6th example of the present invention is described.The 6th example is when carrying out the collection of escalator running sound by collection mixer 17, this event is shown with telltale, so that on-the-spot maintenance staff etc. can hold an example of running-active status.
The explanation of doing such as above-mentioned each example, the collection of the escalator running sound that is undertaken by collection mixer 17 does not rely on on-the-spot maintenance staff's etc. operation, automatically implements under the control of monitor unit 20.Therefore, when the maintenance staff does not recognize that the collection of the escalator running sound that is undertaken by collection mixer 17 is being implemented, sometimes the running-active status of escalator is felt awkward.For example, in the example that describes as the 3rd example, even the maintenance staff wants to make escalator to stop and operating switch 16 is operated, before the collection of the escalator running sound that is undertaken by collection mixer 17 finished, escalator still continued operation.And, in the example that describes as the 4th example, sometimes there is not the passenger, escalator is but from stopping or low speed standby running state is switched to the conventional operation state.And, in the example that describes as the 5th example, sometimes guide the output of sound to stop.In these cases, the meeting such as maintenance staff feels awkward to the running-active status of such escalator.Therefore, in the 6th example, when carrying out the collection of escalator running sound by collection mixer 17, this event is shown with telltale, so that maintenance staff etc. recognize escalator running sound is collected, make it not feel awkward.
As shown in Figure 7, in the 6th example, as the optional position around the escalator of diagnosis object, telltale 50 is set so that maintenance staff etc. can easily confirm.Telltale 50 is connected with monitor unit 20, according to moved control from the output of monitor unit 20.
When illustrated passing through sometime collects the collection of mixer 17 enforcement escalators running sounds in above-mentioned the first to the 4th example, monitor unit 20 is presented at the event of collecting by 17 pairs of escalator runnings of collection mixer sound on the telltale 50 to telltale 50 output action instructions.Then, when the collection of the escalator running sound that is undertaken by collection mixer 17 finishes, to telltale 50 output halt instructions, the display action of telltale 50 is finished.And, also can work as monitor unit 20 when receiving the indication that is intended to escalator running sound is collected from the Long-Range Surveillance Unit 30 of central monitoring position, to telltale 50 output action instructions, make telltale 50 carry out display action, implement simultaneously the collection of the escalator running sound that undertaken by collection mixer 17.
As mentioned above, adopt the abnormity diagnostic system of the 6th example, during carrying out the collection of escalator running sound by collection mixer 17, the event that 50 pairs of telltales are carrying out the collection of escalator running sound shows.Therefore, in the abnormity diagnostic system of the 6th example, the maintenance staff is waited recognize the collection of carrying out escalator running sound, make its running-active status to escalator not feel awkward.
(the 7th example)
Below, the 7th example of the present invention is described.The abnormity diagnostic system of the 7th example, that the voice data that escalator is about to the escalator running sound before the emergent stopping is stored in the memory device 22 of monitor unit 20 inside, its voice data is resolved, and then can carry out an abnormality diagnostic example of escalator.
On the escalator as diagnosis object, generally be provided with the safety device that when abnormal, moves, make the escalator emergent stopping.When making the escalator emergent stopping when the action of this safety device, some equipment breakage etc. occuring sometimes unusual, if can confirm the abnormal sound of this moment, may make problem do sth. in advance solution before stopping.Therefore, in the 7th example, start to stopping period from escalator, monitor unit 20 often makes collection mixer 17 collect escalators running sounds, on one side and with this voice data on one side overwrite store in the internal storage 22.And, in the address writing address directive of voice data on memory device 22 of storing, can from the position of this address pointer, specify the voice data of the escalator running sound in a week that is equivalent to step 10.
As shown in Figure 8, in the 7th example, CPU21 monitors the run signal from the escalator of control desk 5.When being intended to start the run signal of escalator from control desk 5 outputs, at least certain collection mixer 17 among mobile set mixer 17a and fixed set mixer 17b, the 17c is started, and the collection mixer 17 that has started is by the voice data input CPU21 of interface 24a-24c with collected escalator running sound.Then, CPU21 stores the voice data of the escalator inputted running sound in the memory device 22 at any time, simultaneously with the address writing address directive of the stored sound data on the memory device 22.
Being used for of memory device 22 is stored as ring-type with voice data in stored sound data storage device zone, during the address that is assigned with on arriving this memory area last, returns address foremost, begins therefrom the voice data overwrite.During escalator operation, the voice data of sound one side overwrite stores in the memory device 22 on one side CPU21 turns round escalator as described above.When the run signal that is intended to make escalator to stop from control desk 5 output, CPU21 stops the collection of the escalator running sound that is undertaken by collection mixer 17, finishes to the storage of the voice data of memory device 22.
Thus, in memory device 22, preserve the voice data of the escalator running sound before escalator is about to stop, can from the position of address pointer, specifying the voice data of the escalator running sound that stops the last week.Therefore, when escalator emergent stopping, can by its voice data is resolved, detect the said equipment breakage etc.
As mentioned above, adopt the abnormity diagnostic system of the 7th example, the voice data of the running of the escalator before being about to stop sound being saved in the memory device 22 of monitor unit 20 inside.Therefore, in the abnormity diagnostic system of the 7th example, when escalator emergent stopping, its voice data is resolved, thereby the major cause that can detect emergent stopping is equipment breakage etc., can deal with problems ahead of time.
Above-mentioned the first to the 7th example exemplifies an application examples of the present invention, and technical scope of the present invention is not limited to the illustrated content of above-mentioned each example.That is, technical scope of the present invention is not limited to the disclosed concrete technology item of above-mentioned each example, also comprises the various distortion that are easy to derive from the disclosure content, change, substitute technology etc.
