The optical gates sensor of known type is break beam sensor, and this break beam sensor has for the projector of utilizing emitted light signal and the receptor for detecting launched signal.The typical use of break beam sensor determines whether there is obstacle, and this depends on that the whether received device of launched signal detects (that is, whether light beam is interrupted).
Break beam sensor is generally used for automatically-controlled door equipment (such as lift facility or entrance door).Such as, the elevator cage of lift facility is typically provided with the optical gates sensor that there is obstacle (such as people or object) for detecting elevator cab door front.Known optical gates sensor comprises break beam sensor, this break beam sensor outside elevator cab door (that is, when lift car be in stop place time, between elevator cab door and shaft door) form the light curtain of infrared light.This optical gates sensor can have the transmitter array for utilizing emitted light signal and the receiver array for sensed light signal.When optical gates sensor determines that working as the not received device of launched optical signal detects usually, may there is obstacle in elevator cab door front.
The operation of this lift facility depends on that whether optical gates sensor determination obstacle exists.Such as, before lift car can start to move, usually need to confirm to there is not obstacle, and if optical gates sensor determines to there is obstacle, then can prevent elevator cab door from closing.
But the performance of optical gates sensor depends on the operating conditions of lift facility.And if during operating conditions difference, then can determine to there is obstacle mistakenly.Such as, in the environment of dirty especially swollen or many dirt, the material that partially or completely may block the optical signal at projector and/or receptor place can be deposited on optical gates sensor.Therefore, the accumulation of material can stop receptor the optical signal launched by projector to be detected, thus causes optical gates sensor can not correctly determine to there is obstacle, and therefore stops door closedown and lift car to move.Therefore, the operating conditions of difference may cause optical gates sensor to stop normal operation, consequently lift facility withdraw from use, and restriction enters building.The condition of the assembly of optical pickocff itself that other operating conditions that can affect sensor performance comprises the physical alignment of projector and receptor, electronic noise and can change in time and degenerate.
Lift facility is an example of automatically-controlled door equipment, and in this automatically-controlled door equipment, the running down of operating conditions of optical gates sensor finally can cause optical gates sensor to stop normal operation.But, once optical pickocff could not normal operation, usually just only detect the deterioration causing optical gates sensor to stop the operating conditions of normal operation, because the causal investigation about fault can be initiated subsequently.
Therefore, desirable to provide a kind of test method of optical gates sensor of automatically-controlled door equipment.

Detailed description of the invention
Fig. 1 shows lift car 10, optical gates sensor 100 and proving installation 150.
Lift car 10 can move and have a pair elevator cab door 12 in the vertical shaft (not shown) of lift facility, and this can be controlled to open and close by electric life controller to elevator cab door 12.
Lift car 10 is provided with optical gates sensor 100, and this optical gates sensor 100 is attached to lift car 10 by sensor mount 14.Optical gates sensor 100 comprises the transmitter array 101 for launching infrared signal and the receiver array 105 for sensed light signal.Sensor mount 14 is arranged to transmitter array 101 and receiver array 105 to remain in the space between the walls of lift car 10 and lift well.Especially, sensor mount 14 keeps transmitter array 101 and receiver array 105 toward each other and aims at, make they can lift-well door 12 and be arranged on lift facility position of stopping shaft door between space in limit light curtain 103 between them, this light curtain 103 is by independent infrared signal 104(or light beam) array forms.Transmitter array 101 and receiver array 105 comprise multiple independent projector 102 and receptor 106 separately.
Optical gates sensor 100 also comprises rattler 120, and this rattler is used for, when determining to detect from the not received device 106 of optical signal of projector 102, launching audible alarm, as will be explained in details hereinafter.
Proving installation 150 comprises optical attenuator 152 and hold-down arm 153, and this hold-down arm 153 is for manually remaining on appropriate location by optical attenuator.In the present embodiment, optical attenuator 152 comprises the variable window of coefficient of opacity 154, and the coefficient of opacity of this window 154 is variable.The variable window of coefficient of opacity comprises homogeneous liquid crystal layer.Window is frameless thus avoids edge effect.In other embodiments, optical attenuator can comprise the support window for one or more translucent paillon foil and required paillon foil being kept together.The variable window 154 of coefficient of opacity is enough large, to make two or three independent optical signals 104 of light curtain pass.But should be understood that, the variable window 154 of coefficient of opacity can be greater or lesser, and can be positioned such that to only have an optical signal by it.
In the present embodiment, optical attenuator 150 is also provided with display panel 156 and controller, and this controller is for the output of the coefficient of opacity and telltale 156 that control the variable window of coefficient of opacity 154.
Also schematically show optical gates sensor 100 in fig. 2, this optical gates sensor 100 comprise respectively with the single projector of transmitter array 101 and receiver array 105 and receptor to 102,106 relevant details.Receptor 106 be provided with photodiode 107(its usually between the receptor 106 of receiver array), for the treatment of photodiode 107 output and launched optical signal 104 detected.Optical gates sensor 100 also comprises controller 110, and this controller 110 makes projector 102 utilizing emitted light signal 104, and determines that launched whether received device 106 of optical signal 104 detects.
Optical attenuator 152 is shown in the deployed position between projector 102 and receptor 106, thus optical gates sensor is in attenuation state, and under this attenuation state, the optical signal 104 from projector has been attenuated a decrement.In the present embodiment, the coefficient of opacity of the window 154 that the coefficient of opacity of optical attenuator 152 is variable can change to limit multiple different decrement, so optical attenuator 152 is arranged to the arbitrary attenuation state be in by optical gates sensor 100 in multiple attenuation state.Differential declines amount is predetermined, but in other embodiments, and the variable panel of coefficient of opacity can be continuous variable.
In use, when receptor 106 can detect launched optical signal, optical gates sensor 100 considered to be in operative condition.Operative condition and receptor 106 do not have to detect when obstacle that the ability of launched optical signal 104 is relevant between projector 102 and receptor 106.Therefore, in use, when there is obstacle (such as people or object) between projector 102 and receptor 106, optical gates sensor is still in operative condition.
The performance of optical gates sensor 100 is subject to the impact of optics door sensor its Ambient operating conditions out of contior.Such as, operating conditions comprises the electronic noise level of gathering and affect optical gates sensor 100 of material (such as dust and dirt) on the projector 102 of transmitter array 101 and/or the receptor 106 of array acceptor 105.Such as, the electronic noise affecting sensor can be produced by the equipment of the power supply of shared optical gates sensor or other electromagnetic interference source.
Whether the decay of optical signal 104 between projector 102 and receptor 106 can be used for the deterioration of Ambient operating conditions of analog sensor, and be used for measuring optical door sensor 100 and continue or stop normal operation.
Fig. 3 shows the test method of the operation window of the optical gates sensor 100 according to the first embodiment of the present invention.In this example, test corresponds to operation window from the optical block (that is, decay) of the optical signal 104 of projector 102 whether within preset limit nargin 20%, as described in detail below.
Optical gates sensor 100 is in baseline state 100(302 at first), under this baseline state, its normal operation is that can be received device 106 from the optical signal 104 of projector 102 detects (between projector 102 and receptor 106 not obstacle when).
Elevator cab door 12 is unlocked (304) and is held open until proving installation 150 and the optical attenuator 152(306 being in deployable state) together with dispose till, under this deployable state, it is oriented to the optical signal 104 of decaying from least one projector 102.In the present embodiment, the single attenuation state of optical gates sensor is only had to be detected, so optical attenuator is configured to carry out attenuate light signal (308) with the decrement of the limit nargin corresponding to 20%.The minimum simulation that limit nargin corresponds to the operating conditions of optical gates sensor 100 worsens, and this minimum simulation worsens preferably optical gates sensor 100 and can bear, and continues normal operation, as hereinafter described in detail simultaneously.
After delay gate is opened, whether the controller for elevator cab door 12 will exist obstacle to determine whether between transmitter array 101 and array acceptor 105 and can initiate a shutoff operation based on determining.This determines the result of the signal testing carried out based on optical gates sensor, and the whether received device 106 of optical signal 104 that this optical gates sensor determination projector 102 is launched detects.Therefore, whether door shutoff operation occurs whether the optical signal 104 showing to have decayed still can use the optical gates sensor 100 being in attenuation state to be detected by corresponding receptor 106.
Therefore, observe the motion (310) of door and determine whether they close or be held open (312).In the present embodiment, this manually carries out by watching door simply.It should be understood, however, that in other embodiments, motion sensor can be provided the movement for detecting gate.
Move if observed in Men Men shutoff operation, then this shows that controller has been determined to there is not obstacle, therefore can infer that the operation window of the optical block of optical gates sensor is greater than 20%(314).This means that optical gates sensor can continue normal operation, although optical signal is 20% decay with decrement.
If observe door to be held open (allowing the delay realized by electric life controller), then can infer that the operation window of the optical block of optical gates sensor is less than or equal to nargin limit 20%(316).Therefore, operator can by by outcome record in maintenance record or remind service personnel this result to respond this result (318), correction action can be taked.Correct action usually can comprise: the transmitter array 101 of clean optics door sensor 100 and receiver array 105 are to remove any dirt or dust that gather.Then this test method can be repeated, to confirm that for the operation window of optical block be within the acceptable limit (that is, within limit nargin 20%).
Fig. 4 shows another test method according to a second embodiment of the present invention.The present embodiment and above-mentioned first embodiment difference are that this embodiment is suitable for optical gates sensor, this optical gates sensor is configured to when the optical signal 104 from projector 102 is not detected by respective receptor 106 (, when determining to there is obstacle), transmitting can be listened and/or visible alarm.In the present embodiment, optical gates sensor has rattler 120(and sees Fig. 2), this rattler 120 sends audible alarm.
First, as mentioned above, optical gates sensor 100 is in baseline state (302).Do not need to arrange elevator cab door 12 to open, can listen and visible alarm because the method depends on.Optical attenuator is deployed (304) so that optical gates sensor is in attenuation state, and under this attenuation state, the optical signal 104 from least one projector 102 is attenuated with the nargin limit, and this nargin limit is 20% in the present embodiment.
Then, determine whether optical gates sensor 100 sends the visual and/or audible alarm (402,404) that instruction receptor 106 can not detect the optical signal 104 from projector 102.As mentioned above, be confirmed as sending with any one in audible alarm if visual, then can infer that the operation window of the optical block of optical gates sensor is less than or equal to the nargin limit (316).As mentioned above, on the contrary, be not all confirmed as having sent with audible alarm if visual, then can infer that the operation window of the optical block of optical gates sensor is greater than the nargin limit (314).
In the present embodiment, optical gates sensor is only provided with rattler, so do not have visible alarm to be determined.
In this exemplary embodiment, visual and/or audible alarm can pass through hand inspection (that is, by listening to or watch respective alarm) and determines.But in an alternative embodiment, proving installation 150 can be provided with control monitor unit, this control monitor unit comprises optical sensor and/or audio sensor (microphone), is configured to the visual and/or audible alarm sent for automatic detecting optical door sensor.Therefore, control monitor unit can be configured to the alarm detecting the particular type sent by optical gates sensor.
Figure 5 illustrates the operation window of measuring optical door sensor 100 according to the third embodiment of the invention and the method for determination operation nargin.In this example, the method determines the approximate value of the operation window of the optical block of optical gates sensor.
As mentioned above, optical gates sensor 100 is in baseline state (302) at first.
In the present embodiment, optical attenuator 152 is configured to increase decrement gradually, the optical signal 104 launched with at least one projector 102 of decaying gradually.Especially, optical attenuator 152 is configured to progressively increase its coefficient of opacity, to increase the decrement that the optical signal 104 from least one projector 102 is attenuated incrementally.Decrement be configured to preset frequency increase by 1%, its be in the present embodiment every 30 seconds once.In other embodiments, button can be provided to increase decrement as required.
Decrement is set to 1%(502 at first) and dispose optical attenuator (504) so that optical gates sensor 100 is in attenuation state, under this attenuation state, the optical signal 104 from projector 102 has been attenuated 1%.Telltale 156 indicates this decrement.In the present embodiment, display actual attenuation amount, but in other embodiments, such as instruction can be provided by many LED.
The same with the second embodiment of the present invention, determine whether optical gates sensor sends and represent that receptor 106 fails the visible alarm 402 from the optical signal 104 of projector 102 or audible alarm 404 to be detected.
If can to listen or visible alarm is confirmed as sending, then the operation window that can determine optical block is between the decrement 0% of original state (baseline state) corresponding to optical gates sensor and the decrement 1% corresponding to current attenuation state (510).But in this example, when decrement is 1%, optical gates sensor does not send can be listened or visible alarm.
After delay 30 seconds, optical attenuator increases decrement (506) with increment 1%, remains on deployed position (504) simultaneously.In other embodiments, as optical attenuator 152 comprises the example of many interchangeable paillon foils, optical attenuator can leave from deployable state, and making it possible to increases decrement.Alternatively, for continuous print attenuation state, different optical attenuators can be used.
The method continues this circulation, until determine to indicate receptor 106 fail to detect from projector 102 optical signal 104 listen or visible alarm sends.In this example, when the decay of optical gates sensor has been increased to 13%, this situation has occurred once.Therefore, operation window is confirmed as (510) between corresponding between 12% of optical gates sensor normal operation and correspond to optical gates sensor stopping normal operation 13%.
Therefore, operation window can compare (512) with the nargin limit, and this operation window corresponds to the deterioration level of the operating conditions of optical gates sensor, and this deterioration level preferably optical gates sensor can be born, and continues normal operation simultaneously.In this exemplary embodiment, the nargin limit is 20%, and proving installation 150 is provided with the internal memory for storing the nargin limit and the processing unit for carrying out determination operation nargin based on current attenuation amount and attenuation incrementation.Therefore, in this example, determination operation nargin (12%-13%) is less than the nargin limit (20%) (514).Alarm sends to indicate operation window to be less than the nargin limit (518) on telltale 156.
In optional example test, operation window can be confirmed as being greater than the nargin limit (516), and such as, this operation window can be 23%.In the test of such example, proving installation display operation nargin and this operation window can exceed the instruction of the nargin limit on telltale 156.
Figure 6 illustrates the illustrated examples of the tolerance limit of optical gates sensor, this Fig. 6 diagrammatically show the diagram of curves of optical gates sensor 100 along with the deterioration of time variations performance, supposes for making the dirt of the degradation of sensor or dust accumulate in the surface of optical gates sensor 100 with constant rate of speed.Show the performance relevant with the optimum operation condition of optical gates sensor, in this optimum operation condition, preferred ambient operating conditions (that is, do not have dust or accumulating foulants on optical gates sensor 100 and do not affect the obvious electronic noise of sensor).Diagram of curves summary is that the performance of deterioration to optical gates sensor of its hypothesis all operations condition has identical linear effect.
The optimum operation condition this graph illustrated for optical gates sensor 100 be 75% operating limit.This means that optical gates sensor 100 can not detect at the optical signal of optimum operation condition for launch for 75% time.
As illustrated on the graph, 0 month time, the baseline state of sensor is only 95%, this means that reality (and non-optimal) operating conditions causes the performance of sensor to reduce 5%.This may be to have accumulated on sensor 100 or due to the bad aligning of transmitter array 101 and receiver array 105 due to a certain amount of material.Because more material stacking is on a sensor with shading light signal, so the baseline state of sensor worsens in time.Use baseline setting operation after 4 months, sensor will arrive operating limit.
Diagram of curves also show and uses that to correspond respectively to decrement be the result that 5%, 10% and 15% three kinds different nargin limit carry out measuring optical door sensor change operation nargin in time.First, each test all can cause operation window to be greater than the determination of the nargin limit.After 1 month, use the nargin limit be 15% test will produce alarm.On the contrary, use the nargin limit be 5% test can not produce alarm until 3 months in the past till.Therefore, arranging nargin limit is 5%, 10% and 15% can to cause before optical gates sensor fault producing alarm in 1 month, 2 months and 3 months.
Therefore, can find out, the fault of optical gates sensor can be enable to be avoided according to said method test operation nargin.
