The specific embodiment
As shown in figure 16, employed existing position detecting device is arranged on the lift car 100 usually in elevator.The function of this position detecting device is to detect near the detected body 1 that is arranged on the floor by position detector 114, detect the absolute location of lift car 100 in hoist trunk thus, when the contraposition of the floor of floor of carrying out lift car 100 and elevator lobby, the described position detecting device device that is absolutely necessary.In addition, described position detecting device also is used to other function, for example, unexpectedly open in the place that does not have elevator lobby door 109, detect the elevator door opening-closing adimission area that is called as the elevator door opening-closing zone by position detecting device for fear of the door 110 of lift car.
As position detector, for example can use the detector of various non-contact types such as photo-electric detector, magnetic detector (using the detector of magnet and the detector of use high frequency magnetic field etc.) and electrostatic capacity type detector.The photo-electric detector can detect the stronger detected body of orientation accurately, but because the photo-electric detector uses infrared ray, so to be subjected to easily with the sunshine be the external disturbance light of representative and the influence of dust, water droplet etc.On the other hand, magnetic detector does not have photo-electric detector strong orientation like that in its detection range, but because magnetic detector is not vulnerable to the influence of external disturbance light, water, dust and wet goods, so is normally used for the abominable place of environment and requires the place etc. of high reliability.
In addition, when position detecting device is installed in the top of lift car, for detector on the lift car and detected body are carried out accurate contraposition, must adjust the position relation between the floor of the floor of elevator lobby and lift car.
And, as shown in figure 15, the detected body of some position detecting device is arranged on the threshold part of elevator lobby, compare with the occasion that position detecting device is installed in the top of lift car, because the position relation between the floor of elevator lobby and the floor of lift car is relative to the detector on the lift car with detected body, so, need regulate to support in order to carry out accurate contraposition.
In the position detecting device of the threshold part that detected body is arranged on elevator lobby, owing to being the installation exercise that localization criteria carries out detected body, so do not need detected body is adjusted operation with the elevator lobby.But, since detector need relative with detected body to state under detect, so need to use the photo-electric detector of reflection-type and magnetic detector etc.
Fig. 1 represents the structure of an embodiment, structure shown in Figure 1 by the detected body 1 on the threshold 102 that is installed in elevator lobby, be installed in photo-electric detector 2 on the lift car and magnetic detector 3 accordingly with this detected body 1 and the comparator 4 that the output of each detector compares constituted.Detected body 1 is made by the metallic object of iron etc., and comparator 4 is logical operation circuit (AND, OR, NOT, NOR etc.).In addition, magnetic detector 3 is preferably the detector that uses magnet and travel switch, Hall element, high frequency magnetic field (eddy current type detector etc.) etc.And detector not necessarily leaves no choice but use magnetic detector, for example also can use the detector of electrostatic capacity type.
In elevator, the final output 4S (also can use the output 2S of photo-electric detector and the output 3S of magnetic detector) that use obtains from described detector, floor contraposition to lift car and elevator lobby is controlled, and perhaps detects elevator door and whether is positioned at the position that can open and close safely.
The shape of detected body 1 below is described.
The shape of detected body 1 is configured to compare with the length that the part that photo-electric detector 2 passes through is arranged in the detected body 1, and the length of the part that the detector 3 that is magnetic in the detected body 1 passes through is longer.More specifically, preferably the length of detected body 1 is arranged to compare with guaranteeing magnetic detector 3 detection characteristic (Figure 14) in the horizontal direction, more preferably guarantee fully to cover the length of the detection width of photo-electric detector 2 when detecting detected body 1, even the detection width also can cover photo-electric detector 2 when making the mobility scale in gap surpass Y3 and detect detected body 1 time.For example, when the worst-case value of the gap variation that is caused by the inclination of detected body 1 and lift car displacement in the horizontal direction etc. may reach Y4,, then not talkatively can cover the photo-electric detector fully if the response position of magnetic detector 3 is X4.Therefore, the length of the part that the detector 3 that is magnetic in the detected body 1 need be passed through prolongs and the partly corresponding length of the length of X4.
In addition, as other the Design of length method of detected body 1, consider and need to use detected body 1 detect this situation of elevator door opening-closing zone, for example the length setting of detected body 1 can be become the length of the fastened component of using with the switching elevator door identical or less than the length of fastened component.But, this Design of length is being become than the length of fastened component more in short-term, because compare with the zone of the actual fastened component that can open and close elevator door, the length in elevator door opening-closing zone is shorter,, the possibility that the passenger closed the situation in elevator increases so taking place.
And the detection the when length that the part that photo-electric detector 2 passes through is arranged in the detected body 1 for example can require, carries out once again floor contraposition operation according to the detection in elevator door opening-closing zone requires and the detection requirement during by the floor face etc. decides.
Followingly the action example of position detector is described with reference to Fig. 2.
The length of the part of passing through by the detector 3 that is magnetic that prolongs in the detected body 1, even inclination has taken place in detected body 1, because with respect to the response position of photo-electric detector 2, the response position of magnetic detector 3 has sufficient surplus, so can cover photo-electric detector 2.
As other the shape of detected body 1, for example preferred shape shown in Figure 3.In the time of on the threshold 102 that detected body 1 is installed in elevator lobby, the top of detected body 1 is fixed end.For this reason, be that detected body 1 can run-off the straight under the situation of precision of the squareness of threshold 102 of elevator lobby and levelness in the installation site that can't guarantee detected body 1.The maximum position of the gap variation that influenced by this bevelled and produce is roughly in the bottom of detected body 1, so, also can be arranged to only to prolong the length of the part that the detector 3 that is magnetic passes through in the bottom of detected body 1.
As mentioned above, when setting the shape of detected body 1, it is longer than the length that the part that photo-electric detector 2 passes through is arranged in the detected body 1 that length setting by part that the detector 3 that is magnetic in the detected body 1 is passed through becomes, then be not vulnerable to the influence of the gap variation that causes by the displacement of lift car and the inclination of detected body 1 etc., the output that can stably cover photo-electric detector 2 with the output of magnetic detector 3.
Below explanation only will be set than long reason with the corresponding part of position detector (magnetic detector 3) of high reliability when setting the shape of detected body 1.
In normal circumstances, the orientation of magnetic detector than photo-electric detector a little less than, improve relatively difficulty of position detection accuracy.This is because the response position of magnetic detector can change because of the variation in the gap between detector and the detected body.Figure 14 represents that magnetic detector moves in the horizontal direction with respect to detection faces and an example of the detection characteristic of magnetic detector when detecting.As shown in figure 14, move in the horizontal direction and when detecting (direction shown in the arrow 65), response position changes corresponding to the gap Y between magnetic detector 3 and the detected body 1 when magnetic detector 3.When especially detecting detected body 1 on the farther position of ratio gap Y3, magnetic detector 3 just begins response after arriving on the detected body 1.For example, when being Y4 in the gap, the response position of magnetic detector 3 on detected body 1 promptly at the X4 place.Can know that from above-mentioned explanation also with photo-electric detector 2 and magnetic detector 3 time, response position is by magnetic detector 3 decisions, so can't bring into play the position detection with high accuracy function of photo-electric detector 2.
When the gap between magnetic detector and the detected body had produced change, the response position of detector was determined by magnetic detector.The reason that this gap produces change is as follows:
(1) lift car vibrations in the horizontal direction.
In the tractor elevator that uses hoist cable and counterbalanced weight, lift car generally moves along guide rail.Therefore, when distortion has taken place guide rail, lift car will move along this distortion, thereby cause lift car to occur vibrations in the horizontal direction.
(2) inclination of the lift car that causes because of passenger's unbalance loading.
Because the lift car run-off the straight make magnetic detector to face detected body by forward, thereby making to detect apart from equivalence occurring departs from.
(3) inclination of detected body
Because detected body run-off the straight makes can't maintain a certain distance between magnetic detector and the detected body.Cause that detected body bevelled major cause for example has the squareness of installation site and the levelness of detected body and the error when installing etc.
Followingly illustrate that with reference to Figure 11, Figure 12 and Figure 13 the change in gap gives influence photo-electric detector 2 and magnetic detector 3 and that bring with structure.In Figure 11, the shape of detected body 1 is provided on the moving direction of lift car the structure that has equal length with respect to photo-electric detector 2 and magnetic detector 3.As shown in figure 12, under the situation that detected body 1 is installed with respect to magnetic detector 3 on even keels, because the detection range of 3 pairs of detected bodies 1 of magnetic detector is wideer than the detection range of 2 pairs of detected bodies 1 of photo-electric detector, so can cover photo-electric detector 2 fully.But actually, because the influence of the distortion of the vibrations of aforesaid lift car, guide rail and installation error etc. as shown in figure 13, is difficult to the gap 8 of detected body 1 and magnetic detector 3 is remained necessarily.For this reason, may cause and to cover completely photo-electric detector 2.Therefore, in the present embodiment,, in the detected body 1 and length magnetic detector 3 corresponding parts have been prolonged in order effectively photo-electric detector 2 to be covered.
Fig. 4 represents the structure of second embodiment, its by the detected body 1 on the threshold 102 that is installed in elevator lobby, be installed in photo-electric detector 2 on the lift car and magnetic detector 3 (eddy current type detector etc.) accordingly with detected body 1 and the comparator 4 that the output of each detector compares constituted.Wherein, detected body 1 is made by the metallic object of iron etc., and comparator 4 is logical operation circuit (AND, OR, NOT, NOR etc.).In addition, magnetic detector 3 is preferably the detector that uses magnet and travel switch, Hall element, high frequency magnetic field (eddy current type detector etc.) etc.And detector not necessarily leaves no choice but use magnetic detector, for example also can use the detector of electrostatic capacity type.Again, detected body 1 is configured to by protruding member 5 towards the structure of the outstanding certain distance of hoist trunk direction.
Followingly the essentiality of this outstanding structure is described with reference to Fig. 5.When on adopting the threshold 102 that detected body 1 is installed in elevator lobby, carrying out the structure of position probing, there is the problem that causes the flase drop survey because of the hoist trunk inner structure beyond the detected body 1.Especially because magnetic detector 3 is the detectors that are used for detecting the high metallic object of magneto-conductivity (iron etc.), so the sensitivity of general commercially available detector usually with the area of the metallic object that is called as the standard detection body as standard, be used in area than this as on little metallic object of the area of the metallic object of standard detection body and the complex-shaped metallic object time, it be unclear that magnetic detector and whether can respond.In hoist trunk,, the beam 7 of elevator door apparatus 6 and building etc. is for example arranged as above-mentioned metallic object.Especially in recent years the growth of the elevator of machine House-less is very fast, space in the requirement saving hoist trunk is a development tendency from now on, in this kind hoist trunk, except the said structure thing, a greater variety of and detected body 1 probably also can occur and be in works in the identical gap.In addition, because the situation that is provided with of the element of installation in the hoist trunk is different because of the difference of the situation in building, elevator place, therefore, need provide a kind of be not subjected to element of installation in the hoist trunk that the structure that stably only detected body 1 is detected with magnetic detector 3 under the situation that state influences is set.
In the present embodiment, rely on protruding member 5 between detected body 1 and other works, to form the gap, thereby can prevent that the works beyond 3 pairs of detected bodies 1 of magnetic detector from producing the flase drop survey.
Fig. 6 represents the system architecture of the 3rd embodiment, below with reference to Fig. 6 this system architecture is described.
The said system structure by the detected body 1 on the threshold 102 that is installed in elevator lobby, be installed in photo-electric detector 2 on the lift car and magnetic detector 3 (eddy current type detector etc.) accordingly with detected body 1 and the comparator 4 that the output of each detector compares constituted.Wherein, detected body 1 is made by the metallic object of iron etc., and comparator 4 is logical operation circuit (AND, OR, NOT, NOR etc.).In addition, magnetic detector 3 is preferably the detector that uses magnet and travel switch, Hall element, high frequency magnetic field (eddy current type detector etc.) etc.And detector not necessarily leaves no choice but use magnetic detector, for example also can use the detector of electrostatic capacity type.Again, detected body 1 is configured to by protruding member 5 towards the structure of the outstanding certain distance of hoist trunk direction.It is adjacent with trim board (fascia plate) 113 that the installation site of detected body 1 is set to.In addition, the installation site of detected body 1 not only can be arranged to adjacent with trim board 113 in the horizontal direction, but also can be arranged to for example adjacent with the lower end of trim board in vertical direction and be connected.
Below the essentiality of the installation site of this detected body 1 is described.When determining the installation site, need consider whether master's hoist cable 101, stern fast, governor (all not having diagram) etc. can come in contact or twine (with reference to Fig. 7 and Fig. 8) with detected body 1 when earthquake takes place.Especially when the frequent in recent years long period type earthquake that takes place had taken place, the shaking degree of above-mentioned strip shape object may be aggravated significantly, so need consider whether can to come in contact or twine with the strip shape object when in hoist trunk equipment being set.
The phenomenon that strip shape object and detected body 1 contact or twine takes place when the width of the horizontal direction of detected body 1 is narrow easily.Therefore, by detected body 1 is arranged on be difficult to because of width is wide the trim board 113 that comes in contact or twine with the strip shape object near, can prevent that when earthquake takes place strip shape object and detected body 1 from coming in contact or twining.
According to above embodiment, can play following effect.That is, in the present embodiment, by detected body 1 is arranged on be difficult to the trim board 113 that comes in contact or twine with the strip shape object near, can form and be difficult to the structure that comes in contact or twine.
Fig. 9 represents the structure of the 4th embodiment, below with reference to Fig. 9 this structure is described.。
The comparator 4 that this structure is installed in two photo-electric detectors 2 on the lift car and two magnetic detectors 3 accordingly by the detected body 1 on the threshold 102 that is installed in elevator lobby, with detected body 1 and the detector output of detector set that photo-electric detector 2 and magnetic detector 3 are formed compares constitutes.Wherein, detected body 1 is made by the metallic object of iron etc., and comparator 4 is logical operation circuit (AND, OR, NOT, NOR etc.).In addition, magnetic detector 3 is preferably the detector that uses magnet and travel switch, Hall element, high frequency magnetic field (eddy current type detector etc.) etc.And detector not necessarily leaves no choice but use magnetic detector, for example also can use the detector of electrostatic capacity type.
The structure example of using two groups of photo-electric detectors 2 and magnetic detector 3 is used during as the reliability that improves position detecting system at needs etc.But, as shown in figure 10, when wanting detector with identical type to be set together, exist between the detector of identical type to produce the problem of disturbing.The photo-electric detector can be subjected to the interference of light each other, and magnetic detector can be subjected to the interference in magnetic field each other, therefore, when the adjacent detector that identical type is set of needs, needs spaced apart the setting.So, in the occasion of Figure 10, need the width of the detected body 1 of additive incrementation, make can not produce interference between each detector in the horizontal direction.
In the time of on the threshold 102 that detected body 1 is installed in elevator lobby, owing to the increase of the elevator of machine House-less and the requirement of building aspect etc. in recent years, the situation that width is set of detected body 1 may take place to guarantee.Therefore, need carry out miniaturization to set detected body and detector.
In the present embodiment, alternately be provided with by detecting the different detector of principle, must consider in the time of can guaranteeing that detector with identical type is set together by the size of detector for avoiding disturbing required distance.According to above-mentioned setting, can save the space of detector, and also check-out console and detector can be set in the place of space requirement strictness.
