The receptor that measurement mechanism has at least one projector and sets.The ray that projector transmitting can be received by receptor.Receptor can directly or with the control unit being connected coordinate and trigger reaction according to the ray receiving.Optionally can also make parasite become the component part of measurement mechanism.Here, parasite directly or by one or more parasites reflexes to receptor by the ray of being launched by projector.In an illustrated embodiment, projector is preferably designed to light source, and it is with appreciiable or sightless range of wavelength transmitting light beam.Correspondingly, receptor has photosensitive ranges of sensors, and it has realized the reception of light beam.
In conjunction with two transition conditions in Figure 1A and 1B, the first embodiment of the present invention is described.Wherein show the lift facility 10 of simplification, have upper lift car A1 and lower lift car A2, both can be substantially move along travel direction z in independently vertically on the common moving track 11 of lift facility 10, such as lift well 11.For this reason, lift car A1, A2 can be furnished with actuating device and each lift car A1, A2 are furnished with a drg, or such as being connected in central drive system, in order to realize along the independent of moving track 11, moves.The annex in addition with other, uses so that the lift car of lift facility can move independently.Lift car can also on even keel under the corresponding configuration of moving track or to other direction running.
Measurement mechanism is set, and it has the first projector such as comprising, such as the first photoelectric measuring device 20 of light source 21, and this light source is arranged in the lower area of lift car A1, as schematically shown in Figure 1A and 1B.What be specially adapted to light source is light-emitting diode, the light of its transmitting bunchy.Applicable is laser diode or solid statelaser better.
In addition, measurement mechanism 20 also comprises the first receptor 22, and it is included in the photosensitive first sensor region 22 of the upper area of lower lift car A2.Sensor region 22 can adopt photodiode, phototransistor or other photosensor.
The design of the first light source 21 and set-up mode are that it is the first ray with the bunchy of light beam L1 form with the first angle W1 transmitting with respect to travel direction z.Light beam L1 is orientated downwards in an illustrated embodiment.
A kind of transition condition (distance between car is S1) has been shown in Figure 1A, and wherein, upper lift car A1 moves down with speed v 1, lower lift car A2 static (v2=0).Shown in the moment, light beam L1 is mapped on the wall of the lift well 11 of the arbitrary position above lower lift car A2.
If the relative distance of two lift car A1 and A2 is reduced to minor increment S2 (as shown in Figure 1B), light beam L1 shines the sensor region 22 of receptor first.
According to the present invention, the default or setting means of the first angle W1 is that, as long as reach minor increment S2 when upper and lower lift car A1, A2 approach, the first light beam L1 just shines first sensor region 22.Therefore, at this, irradiate constantly and can trigger reaction R1 by the first receptor 22,24 detecting light beam L1 and this receptor 22,24, it is such as further arriving control setup or allied equipment by wire or connecting device 23.
The present invention allows different embodiments or the structural level of measurement mechanism.
In the simplest embodiment, can directly when shining sensor region 22 for the first time, trigger light beam L1 reaction.Sufficient condition is in this case, in the meaning that sensor region 22 extends on surface, has certain size, even this size can be guaranteed also can realize in the situation that lift facility 10 rocks by receptor 22,24 detecting light beam L1 reliably.
Another embodiment of the invention is shown in Figure 2.Shown in this figure after detecting light beam L1 by the photosensitive segmentation 22.1 of sensor region 22 first the transition condition of shorter time.
These sectional optimizations can be evaluated individually, and it has respectively independent electrical interface.Corresponding evaluation system 24 (or the in the situation that of Fig. 3 24 and 28) is preferably set in different embodiments, in order to which segmentation that can shine in segmentation 22.1-22.n according to the first light beam L1, triggers suitable reaction (R1, R2, R3, R4).
If supposed and distance identical in Figure 1A and 1B, shown in moment distance be less than S2.
Because upper lift car A1 continues to move with the downward lift car A2 of speed v 1, " luminous point " producing by light beam L1 shifts left.Measurement mechanism can so design now, programmes or set, and makes send early warning as reaction or bring lift facility 10, particularly lift car A1 and/or A2 into modes of warning when the segmentation 22.1 that shines for the first time sensor region 22.If other segmentation 22.4 of definite sensor region 22 before luminous point has surpassed now, can trigger final reaction (such as brake equipment or anti-fall drg by lift car A1, A2 above and/or under triggering carry out emergency braking).The mode of this two-stage provides extra reliability and has helped avoid wrong triggering.
Now, by means of Fig. 2, set forth another embodiment of the invention.As shown in by the arrow of sensor region 22 belows, if the relative distance between lift car A1, A2 reduces with speed v 1, luminous point is with speed v 1
*be moved to the left.This speed v 1
*permission passes through to calculate acquisition speed v1 in the situation that using simple trigonometric function method.If angle W1 is such as being 45 degree, v1=v1
*, because tan45=1.If angle W1 is greater than 45 degree, v1
*also be greater than v1.If angle W1 is less than 45 degree, v1
*be less than v1, realize and slow down or slow down.By this type of, slowed down and can be reduced the size of sensor region 22, this is favourable, because corresponding sensor is more expensive.
Figure 3 illustrates another modification.This modification is preferred, because it provides larger reliability.As shown in the figure, two photoelectric measuring devices have been adopted.The first measurement mechanism is similar to a system setting shown in the drawings.The second measurement mechanism can have identical structure, but proximate mirror is arranged in the upper area of lower lift car A2 symmetrically.Corresponding the second sensor region 26 is arranged in the lower area of lift car A1.
In an illustrated embodiment, two angles are identical, i.e. W1=W2.Described angle can also differently be preset or set.In the situation that if the embodiment of photoelectric measuring device is identical and W1=W2, two photoelectric measuring devices are at identical time signaling, or trigger reaction R3, R4 in the identical time.
Schematically illustrated in the drawings, receptor triggers respectively reaction.This type of reacts according to the difference of the embodiment of equipment, programming or setting and difference.Illustrate in the drawings, receptor can send signal or information by wire or other connecting device 23 or 27.Then or processed before triggering reaction, or such as directly triggering reaction by opening a switch, wherein switch is the parts of vital circuit for this signal or information.
Exist and much complete the possibility that triggers reaction.Each embodiment depends on respectively the different details of each lift facility 10.If in lift facility 10 such as each lift car A1, A2 have self a vital circuit, the vital circuit of lift car A1, A2 above and/or under can interrupting by one or more receptors.
In lift facility 10, preferably each lift car A1, A2 have self a vital circuit, wherein, and a plurality of safety elements, such as safe contact or safety switch are arranged in circuit series.Corresponding lift car A1 or A2 are only in vital circuit and can move during all safe contact closure being incorporated into wherein thus.Vital circuit is connected with actuating device or the brake unit of lift facility 10, in order to interrupt travelling of corresponding lift car A1 or A2 in needs this type of whens reaction.
The present invention can also apply to the described vital circuit of replacement to be furnished with in the lift facility of safety bus system.
Replaceable or be additional to and disconnect vital circuit, can also trigger the drg of each lift car A1, A2.
Replaceable or additional also has, and can trigger the possible anti-fall drg of each lift car A1, A2.
According to the difference of embodiment, can trigger one or more following reactions by receptor 22,24 or 26,28:
-disconnect the vital circuit of at least one lift car A1, A2,
-to elevator control gear transmission of signal,
-trigger the brake equipment of at least one lift car A1, A2,
-trigger the anti-fall drg of at least one lift car A1, A2,
-at least one lift car A1, A2 are transformed into alert status,
