The specific embodiment
Below in conjunction with a description of drawings preferred embodiment of the present utility model.
At first the explanation, in this preferred embodiment, adopted Hall switch inductor 2 and 3 and magnetic stripe 4 as inductor and sensed device.
As shown in Figure 1, in this preferred embodiment, the elevator data measurement unit comprises support 1, two Hall switch inductors 2 and 3,24 magnetic stripes 4, counting machine 5, elevator speed calculating unit 6; Elevator service direction judging unit 7; Elevator position calculating unit 8.In addition, also shown the velocity limiter wheel or the governor tension pulley 9 that rotate with the operation of elevator among Fig. 1, elevator data measurement unit of the present utility model promptly is mounted thereon.Wherein, the center of circle of a plurality of magnetic stripes 4 and velocity limiter wheel or governor tension pulley 9 equidistantly is installed on the outer rim of the velocity limiter wheel of elevator that diameter is D or governor tension pulley 9 and rotates thereupon.Two Hall switch inductors 2 and 3 two position spaced that then are installed on the support 1, on these two positions, Hall switch inductor 2 and 3 can be discerned the magnetic stripe 4 of process.
The working process of device of the present utility model is briefly described as follows: during the elevator operation, drive velocity limiter wheel or governor tension pulley 9 rotations, the a plurality of magnetic stripes 4 that are mounted thereon rotate thereupon, at this moment detect the magnetic stripe 4 of processes by being fixed on Hall switch inductor 2 and 3 on the support 1,5 pairs of Hall switch inductors 2 of counting machine and 3 recognition result are handled then, obtain absolute counting pulse C, elevator speed calculating unit 6 utilizes diameter D and the total number of magnet and the absolute counting pulse C and the respective detection time that detection obtains of velocity limiter wheel or governor tension pulley 9, can obtain elevator speed; Elevator service direction judging unit 7 can obtain the elevator service direction by magnetic stripe 4 is discerned through the sequencing of Hall switch inductor 2 and 3; In addition, 8 couples of count pulse C of elevator position calculating unit and elevator service direction are handled and can be obtained elevator position.
Specify elevator speed calculating unit 6, elevator service direction judging unit 7 and elevator position calculating unit 8 below and calculate the principle of elevator speed, direction and position respectively.
Figure 2 shows that being installed among Fig. 1 drives the relative position scheme drawing that magnetic stripe 4 on velocity limiter wheel or governor tension pulley 9 outer rims launches back and Hall switch inductor 2 and 3, black part is wherein divided expression magnetic stripe 4, white portion is represented the interval between the magnetic stripe 4, this is an embodiment of the installation site of hall sensor 2 and 3, and two hall sensors 2 and 3 can be sensed same magnetic stripe 4 simultaneously in this embodiment.In one embodiment, magnetic stripe spacing=magnetic stripe width=K=30mm, magnetic stripe 4 is apart from the back gauge d=5mm of Hall switch inductor 2 and 3.And Figure 3 shows that another embodiment of the installation site of hall sensor 2 and 3, wherein hall sensor 2 and 3 can be sensed two adjacent magnetic stripes 4 respectively.And in the present embodiment, the length of each magnetic stripe 4 can equal the spacing between it, all is K, then because magnetic stripe 4 all is installed on the outer rim of velocity limiter wheel or governor tension pulley 9, so 2*24K=π * D.
The relation of the output of the service direction of elevator and hall sensor 2 and 3 at first is described.When supposing ascending for elevator, velocity limiter wheel or governor tension pulley 9 clockwises rotate, promptly at this moment in Fig. 2 and 3 each magnetic stripe 4 move right; Otherwise when elevator was descending, its inverse clock rotated, promptly at this moment in Fig. 2 and 3 each magnetic stripe 4 be moved to the left; And suppose Hall switch inductor 2 and 3 output low level when detecting magnetic stripe 4 regional, otherwise output high level.Then when elevator moves, for hall sensor shown in Figure 22 and 3 and the relative installation of magnetic stripe 4, can obtain Fig. 4 and the sequential chart of elevator the time shown in Figure 5 respectively in uplink and downlink, wherein the output of Hall switch inductor 2 is expressed as the A phase, the output of Hall switch inductor 3 is expressed as the B phase, and the count pulse that counting machine 6 is exported is expressed as C (how count pulse C is illustrated below).
As seen, A is angle difference and essentially identical two signals of waveform to some extent with B mutually mutually from Fig. 4 and Fig. 5.In the present embodiment, as shown in Figure 2, because Hall switch inductor 2 is positioned at the left side of Hall switch inductor 3, and the front has supposed that the ascending for elevator correspondence magnetic stripe 4 and move right, therefore when ascending for elevator, the positive rise of the output signal B phase of Hall switch inductor 3 is necessarily early than the positive rise of the output signal A phase of Hall switch inductor 2.Otherwise when elevator was descending, the positive rise of the output signal B phase of Hall switch inductor 3 necessarily was later than the positive rise of the output signal A phase of Hall switch inductor 2.
Can judge the elevator service direction by the output of Hall switch inductor 2 and 3 according to this principle, particular content is as described below.As shown in Figure 4, if A detect mutually level from high to low and B detect mutually and be low level, or A detect mutually level from low to high and B detect mutually and be high level, judge that then the elevator service direction is up, if promptly the positive rise of hall sensor 2 is later than the positive rise of hall sensor 3, then can conclude ascending for elevator.As shown in Figure 5, if A detect mutually level from high to low and B detect mutually and be high level, or A detect mutually level from low to high and B detect mutually and be low level, judge that then the elevator service direction is descending, if promptly the positive rise of hall sensor 2 is early than the positive rise of hall sensor 3, can conclude that then elevator is descending.
Because the utility model need utilize the sequencing of magnetic stripe 4 by two Hall switch inductors 2 and 3 to the judgement of elevator service direction, so the position when requiring two Hall switch inductors 2 and 3 to install must be accurate, can install with reference to Fig. 2 and installation site shown in Figure 3.In this explanation, in real work, in order to guarantee that enough contact surface simultaneously for the detection in the service direction of the uplink and downlink that adapt to elevator, shown in Fig. 2 and 3, requires the edge of two Hall switch inductors 2 and 3 and the edge of magnetic stripe 4 to have apart from d.The value of this d value generally determines that according to tension wheel diameter and actual conditions provide empirical value at this: when K value scope was 2～100mm, d value scope was 1～50mm.It is 4*d=K that desirable d and the value of K are closed, and d is big more, and the angle that A phase and B phase signals are separated by is just more little.
In addition, utilize the output of Hall switch inductor 2 and 3 calculate elevator speed method can for: at first obtain absolute counting pulse C and (promptly do not consider direction by counting machine 6, the only pulse that obtains according to A phase and B level mutually), shown in the position that dotted line indicated in the Figure 4 and 5, with positive rise evening to signal be as the criterion, output count pulse C, for example the positive rise of A phase is later than the positive rise of B phase among Fig. 4, so output and the essentially identical count pulse C of A phase signals, and the positive rise of B phase is later than the positive rise of A phase among Fig. 5, so export and the essentially identical count pulse C of B phase signals.。Secondly, calculate elevator speed V=[(π * D by elevator speed calculating unit 6)/N] * (C/T), wherein: V is an elevator speed, π is a circular constant, and D is the velocity limiter wheel of elevator or the diameter of governor tension pulley 9, and N is the number of magnetic stripe 4, C is a count pulse, and T is the time.At a specific embodiment, D wherein and N are definite values, and it is variable that count pulse C and time T are only arranged, and as seen utilize the count pulse in the unit time to obtain elevator speed V.
In addition, the principle of elevator position calculating unit 8 concrete calculating elevator positions is as described below.In elevator position calculating unit 8, comprise an elevator position self study unit, its self study principle is moved from 1 course for making elevator, and note when just in time running to the integer floor, the comparative counting pulse C of counting machine 5 outputs is (after promptly obtaining current absolute counting pulse, also to calculate:, then former comparative counting pulse is added that current absolute counting pulse can obtain the comparative counting pulse if direction is up in conjunction with the elevator service direction; If direction is descending, then from former comparative counting pulse, deducts current absolute counting pulse and can obtain the comparative counting pulse) value, at this count pulse C that self study process obtains is designated as C0; And also make elevator from the underground operation of 1 course, note when just in time running to the integer floor, the value of the count pulse C0 of counting machine 5 output, so through repeatedly self study, then can obtain elevator position is the data of the corresponding relation of place number of floor levels and corresponding counts pulse C0.For example, as shown in Figure 6, in the self study process, make elevator move, when just in time running to the 2nd layer, suppose that the count pulse C0 of counting machine 5 outputs is 100 from the 1st course; And when just in time running to the 3rd layer, the count pulse C0 that establishes counting machine 5 outputs is 200; When just in time running to the 4th layer, the count pulse C0 that establishes counting machine 5 output is 300, and in addition, when elevator ran to the-1 layer and the-2 layers, C0 was respectively-100 and-200.Limited because of length in Fig. 6, only provided the elevator position and the corresponding relation scheme drawing of corresponding counts pulse C0 value in 4 layers and underground 2 layers on the ground, the related data of other floor can obtain according to this in the reality use.
In the elevator actual moving process, count pulse C and elevator service direction can be utilized so, cooresponding elevator position can be calculated.As when elevator when the 1st layer rises to the 2nd layer, the absolute counting pulse C1=100 of counting machine 6 outputs, be up then in conjunction with the elevator service direction, can obtain the comparative counting pulse and equal this absolute counting pulse C1=100, the C0 value that writes down in this comparative counting pulse C1 value 100 and the elevator position self study unit is contrasted, and the current location that can determine elevator is the 2nd layer;
If elevator continues to have risen to the 4th layer from the 2nd layer, the absolute counting pulse C1=201 (admitting of a little error) of counting machine 6 outputs, be up then in conjunction with the elevator service direction, above absolute C1 value 100 add that the current absolute C1 value 201 that obtains obtains current relative C1 value=301, the current location that then can determine elevator is the 4th layer;
Elevator may drop to the 3rd layer then, the absolute counting pulse C1=100 of counting machine 6 output then, and the elevator service direction is descending, so relative C1 value=301 deduct the current absolute C1 value 100 that obtains and obtain current relative C1 value=201 before utilizing elevator to descend, the current location that then can confirm elevator is the 3rd layer.
Certainly is not the situation that just in time rests in the integer floor for elevator, and elevator runs down to underground situation from 0 layer or other floor, also can utilize the mode identical to calculate elevator position with foregoing.
Foregoing only is a preferred embodiment of the present utility model, except the hall sensor 2 shown in Fig. 2 and 3 and 3 and the relative position of magnetic stripe, described two hall sensors 2 and 3 magnet of can also being separated by is arbitrarily laid.For example for the embodiment that always has 24 magnetic stripes 4, these two hall sensors 2 and 30 to 23 magnetic stripe 4 of can being separated by, 0 magnetic stripe 4 of being separated by is a situation shown in Figure 2, and 1 magnetic stripe 4 of being separated by is a situation shown in Figure 3, and other situation can the rest may be inferred.In the present embodiment, have uniform spacing between the magnetic stripe 4, but in actual use, the spacing between the magnetic stripe 4 can be unfixed, have and sense simultaneously or respond to period less than magnetic stripe 4 as long as satisfy hall sensor 2 and 3.In real work, the distance between magnetic stripe plane, 4 place and the hall sensor 2,3 generally is taken as 0mm～50mm.
At first explanation, in this preferred embodiment, adopted Hall switch inductor and magnetic stripe as inductor and sensed device, but in actual applications, also can adopt other the switching regulator sensing unit and sensing unit as: near switch and metal, or photoelectric switch and grating dish etc., though these sensing units belong to dissimilar, the effect that can finish the sensed device of identification and export recognition result.In addition, in this preferred embodiment, can suppose when described sensing unit A and B sense described sensing unit, the recognition result A of described output mutually or B be respectively high level mutually; The recognition result A phase or the B of described output then are not respectively low level mutually otherwise in induction; And counting unit is carried out following processing mutually to the recognition result A phase or the B of described high level or low level form: when the both is high level, and described counting unit output high level; When the both is low level, then described counting unit output low level; The output of the high and low level of counting unit is count pulse C.But in actual applications, also may since other of the difference of inductor or circuit layout need, when described sensing unit A and B sense described sensing unit, the recognition result A of described output mutually or B be respectively low level mutually; The recognition result A phase or the B of described output then are not respectively high level mutually otherwise in induction; And counting unit to the recognition result A of described high level or low level form mutually or B can carry out the processing identical mutually with above-mentioned processing mode, perhaps be different from the following processing of above-mentioned processing mode: when the both is high level, described counting unit output low level; When the both is low level, then described counting unit output high level; The output of the high and low level of counting unit is count pulse C.Those skilled in the art will appreciate that in specific circuit design, can be diversified for the combination of high and low level, does not therefore repeat them here.
The foregoing description only is used to illustrate the utility model; those skilled in the art can make various modifications or replacement to embodiment of the present utility model; and not departing from the bright spirit of the utility model, these modifications or replacement should be considered as dropping in the protection domain of the present utility model.Protection domain of the present utility model is as the criterion with claims institute restricted portion.
