Detailed description of the invention
Referring to accompanying drawing, one embodiment is described in detail.
Fig. 1 is the integral structure figure that represents an embodiment, and wherein 102 represent Room every bank, and 115 represent floor.The hoist trunk of elevator is formed in building, and lift car 100 moves across multiple floors in hoist trunk, and is connected with counterbalanced weight 111 by hoist cable 101.Drive rope sheave 103 by electrical motor 105, make thus lift car 100 move.The driving of electrical motor 105 is supplied by power inverter 107 with electric power.In addition, the impulse deviser 106 of coder etc. is arranged on electrical motor 105, impulse deviser 106 is pulsing along with the rotation of electrical motor, by system controller 108, this pulse is counted, can be calculated speed, equivalent position and the miles of relative movement etc. of lift car 100 on hoist trunk moving direction of drive motor 105.On lift car 100, be provided with the elevator cab door 110 engaging with hoistway door 9 and open and close together with hoistway door 9.
In lift car 100 sides, primary importance detecting sensor 3 and second place detecting sensor 4 separate predetermined distance setting in the lifting direction of lift car 100, and the output of each sensor is connected with system controller 108 by logical-arithmetic unit (comparator) 5.In elevator lobby side, tested drafting board 1 is arranged on the door 102 of Room door accordingly with the position-detection sensor 3,4 of photo-electric.Detect tested drafting board 1 by position-detection sensor 3,4, can detect thus the position of lift car in hoist trunk.In addition, by detecting tested drafting board 1, can carry out contraposition (floor is stopped and detected) and detect elevator door opening and closing region (elevator door that allows elevator cab door 110 to open with respect to hoistway door 109 can open and close region) to the height and position of the floor of the floor of lift car and elevator lobby.
As the function of the position detecting device of position-based detecting sensor 3,4, there is floor level again to bit function, in the time having produced small difference of height between lift car 100 and floor 115, tripped because of difference of height for fear of passenger, make elevator action, so that in opening elevator door, the floor of the floor to lift car and elevator lobby is carried out contraposition so that both are consistent again.Conventionally quickly when upper and lower elevator, there is flexible produce because the weight variation of lift car makes hoist cable a large amount of passengers in above-mentioned small difference of height.Position detecting device can detect this small difference of height.
As position-detection sensor, can use the non-contact type detecting sensor of electro-optical pickoff, magnetic pickup device (using the sensor of magnet and use high frequency magnetic field etc.) and electrostatic capacitive.Wherein, tested drafting board is irradiated infrared light etc. and detects its catoptrical reflection-type photoelectricity formula sensor, because hoist cable when earthquake etc. etc. can not hook sensor self or tested drafting board 1, and because orientation can detect by force tested drafting board accurately, so more favourable.But, in the time using infrared light, likely can produce error detection action because of the interference of exterior light and dust, water droplet etc. taking sunshine as representative.
Especially, in the time having there is error detection or fault in the position-detection sensor that can open and close region for detection of elevator door, under some failure mode, although can make elevator be positioned at elevator cab door 110 position not to be opened/closed because of error detection, but can open and close elevator door is opened mistakenly because sensor is identified as elevator door by mistake, although or elevator is positioned at elevator cab door position to be opened/closed, cannot opens and closes and cause passenger to be closed in lift car because sensor is identified as elevator door by mistake.
Fig. 2 represents the detailed structure of door 102 parts of Room door.On the door 102 of Room door, be provided with for the protection of toe and prevent people fall into the toeguard (Toe Guard) 113 in hoist trunk and made by metallic object or plastics etc. such as iron for catoptrical tested drafting board 1.Position-detection sensor 3 and 4 and tested drafting board 1 be arranged on accordingly on lift car 100.Sensor output 3S and the 4S of position-detection sensor 3 and 4 are input in logical-arithmetic unit 5.Logical-arithmetic unit 5 is logical operation circuits, consists of the computing of logic IC or microcomputer.
Position-detection sensor 3 and 4 moving directions at lift car 100 (short transverse) are upper coaxial to be arranged, and the interval that arranges is between the two decided detecting the mode that elevator door can open and close region according to the output signal 5S of logical-arithmetic unit 5.The floor contraposition (make floor level consistent) that elevator carries out lift car 100 and elevator lobby according to final output signal 3S, 4S and 5S is controlled, and detects and represent that the elevator door whether lift car 100 is positioned on each height and position that can open and close safely can open and close region.That is to say, be that signal 5S detects elevator door and can open and close region according to signal 3S and 4S being carried out to logic OR output that computing obtains by logical-arithmetic unit 5, and carry out floor level contraposition processing again according to signal 3S and 4S.Be specifically, length setting by tested drafting board 1 in lifting direction is can open and close the corresponding length L in region 1 with elevator door, and the interval S between two position-detection sensors 3 and 4 is set as being less than length L 1, can implements floor level again to bit function according to both differences thus.
Fig. 3 be illustrated in lifting direction, separate position-detection sensor 3 that predetermined distance (S) arranges and 4 and tested drafting board 1 between arrangement relation, in order to obtain symmetrically up and down floor level again to bit function, rest under the state on floor at lift car 100, the line of centers of position-detection sensor 3 and 4 in lifting direction is consistent with the line of centers of tested drafting board 1.Length L 1 and the more small difference of height of bit function to be detected to length M be the size of predetermining for implementing floor level.
The interval S of position-detection sensor 3 and 4 is set to, and can to carry out to signal 3S and 4S the logic OR output that computing obtains by logical-arithmetic unit 5 according to the movement along with lift car 100 be that signal 5S detects length L 1.That is to say, be set as L1=S+2M, interval S=L1-2M.
Fig. 4 represents till lift car 100 is accommodated to the variable condition of each signal of the floor that tested drafting board 1 is installed.State when (a) in figure represents lift car dock floor to (c), state when (d) lift car 100, because of certain reason, displacement has occurred after expression dock floor.When lift car 100 is as shown in (a) between floor time, position-detection sensor 3 and 4 is not because detecting that tested drafting board 1 is in disconnecting (OFF) state, then, in the time that lift car 100 arrives the destination floor that will stop (becoming the state shown in (b)), position-detection sensor 4 becomes conducting (ON) state because tested drafting board 1 being detected.In addition, when in state shown in (b), 3S and 4S are carried out to OR judgement and the signal 5S that obtains also becomes conducting, can know that thus elevator has arrived elevator door and can open and close region.
After this, after lift car 100 dock floors, become the state shown in (c), each signal all becomes conducting state.In the time that lift car 100 slightly moves towards top and makes, between the floor of lift car 100 and the floor of elevator lobby 115, small difference of height has occurred under (c) state, become the state shown in (d), under this state, because position-detection sensor 3 has exceeded the scope that can detect tested drafting board 1, so logical-arithmetic unit 5 is that signal 3S is that disconnection and signal 4S are that logic operation is carried out in conducting according to the state of each signal, because the result of logic operation is 01, although be positioned at elevator door and can open and close region but occur skew towards top so be judged as lift car 100.Now, if general plan is micro-has down carried out when mobile for lift car 100, because signal 3S is conducting, signal 4, for disconnecting, so the result of logic operation is 10, is now judged as towards below and has occurred skew.
In addition, the information of the impulse deviser 106 for detection of lift car 100 moving directions and the information of the lift car moving direction that obtains according to signal 3S, 4S are compared, being judged as both when inconsistent, elevator is stopped.
In the time that lift car 100 has moved the small difference of height detection length M shown in Fig. 3, becoming the position-detection sensor 3 that only has shown in (d) is the state disconnecting.Therefore,, in the time position-detection sensor 3 being detected for off-state, system controller 108 sends and makes lift car 100 move the instruction that detects the corresponding distance of length M with small difference of height, to again carry out the contraposition of floor stop position.
As mentioned above, only need use location detecting sensor 3 and 4, just can realize elevator door simultaneously and can open and close region measuring ability and floor level again to bit function, thereby can realize multifunction.In addition, when the side in position-detection sensor 3 and 4 becomes off-state because having there is fault, because signal 5S is still conducting, detect so at least can open and close region to elevator door.Again, can be according to the logic AND output signal of position-detection sensor 3 and 4, being determined by logical-arithmetic unit 5 or system controller 108 is that fault has occurred for which in position-detection sensor 3 and 4.
In Fig. 5, increase by the 3rd position-detection sensor 2, now, as shown in Figure 5, there is tested drafting board 1 on the door 102 that is arranged on Room door, be arranged on accordingly with this tested drafting board 1 logical-arithmetic unit 5 that the position-detection sensor 2,3 and 4 on lift car 100 and the output signal 3S to position-detection sensor 3 and 4 and 4S compare.The length that the shape of tested drafting board 1 is formed the side that the Length Ratio position-detection sensor 3 and 4 of the side that the position-detection sensor 2 of the moving direction of lift car 100 passes through passes through is long.
Position-detection sensor 2 on the moving direction of lift car 100 with position-detection sensor 3 and 4 disalignments, be arranged on different listing, position-detection sensor 3 and 4 is coaxial setting.Can make the output signal 5S mode identical with the output signal 2S of position-detection sensor 2 of logical-arithmetic unit 5 decide the shape of tested drafting board 1 and the arrangement of position-detection sensor 2,3 and 4, can realize elevator door and can open and close by signal 2S and 5S thus the redundancy of the measuring ability in region.Therefore, even if fault has occurred position-detection sensor self, also can continue to maintain elevator door and can open and close the measuring ability in region, can be used as the safety that further improves for subsequent use.
Fig. 6 shows the deployment scenarios of tested drafting board 1 and position-detection sensor 2,3 and 4, wherein, can open and close length L corresponding to region 1 and the more small difference of height of bit function to be detected to length M be the size of predetermining for implementing floor level with elevator door.The position of position-detection sensor 2 is positioned at the central authorities of position-detection sensor 3 and 4 on above-below direction, and it is that signal 5S is consistent with the length that elevator door can open and close region that the interval S between position-detection sensor 3 and 4 and the length y of tested drafting board 1 are set to the OR output that makes by logical-arithmetic unit 5, signal 3S and 4S to be carried out to computing along with the movement of lift car 100 and obtain.
In the tested drafting board 1 of Fig. 6, in order to make position-detection sensor 2 and can to open and close length L corresponding to region with respect to the elevator door being detected by 1 position transduser passing through with it, to be central authorities symmetrical, the length setting of the side that position-detection sensor 3 and 4 is passed through is y, and equal difference upper and lower length y is set as to x, namely be set as L=2x+y, and with respect to the interval S between position-detection sensor 3 and 4, x=S/2.And, length y is set at the floor of lift car and the height of floor from rail top of elevator lobby when consistent, the distance that position-detection sensor 3 and 4 lays respectively at the marginal portion from tested drafting board 1 of the inner side of tested drafting board 1 is the position that small difference of height detects length M, therefore y=S+2M.
Thus, the shape of tested drafting board 1 is set to by obtaining S and y, obtains S=(L-2M)/2, y=(L+2M)/2, and the OR signal 5S that logical-arithmetic unit 5 is exported is identical with the output signal 2S of the 3rd position-detection sensor 2.
Fig. 7 represents till lift car 100 is accommodated to the variable condition of each signal of the floor that tested drafting board 1 is installed.State when (a) in figure represents lift car dock floor to (c), state when (d) lift car 100, because of certain reason, displacement has occurred after expression dock floor.When lift car is as shown in (a) between floor time, position-detection sensor 2,3 and 4 is not because detecting that tested drafting board 1 is in OFF (disconnection) state, then, in the time that lift car 100 arrives the destination floor that will stop (becoming the state shown in (b)), position-detection sensor 2 and 4 becomes ON (conducting) state because tested drafting board 1 being detected.In addition, when in state shown in (b), 3S and 4S are carried out to OR logic operation and the OR output signal 5S that obtains also becomes conducting, and the detection that can make elevator door can open and close region thus realizes dual, can under the state that has improved redundancy, detect thus.
After this, lift car 100 becomes the floor shown in (c) and stops state, and the output of each signal all becomes conducting state.When lift car 100 under (c) state because of passenger quickly upper and lower elevator make that hoist cable is flexible causes lift car 100 slightly to move, while making, between the floor of lift car 100 and the floor of elevator lobby 115, small difference of height has occurred, become the state shown in (d), under this state, because position-detection sensor 3 has exceeded the scope that can detect tested drafting board 1, so signal 4S becomes conducting, logical-arithmetic unit 5 according to the state of signal 3S and 4S (logic operation) although be judged as lift car 100 and be positioned at elevator door and can open and close region but occur skew towards top.On the contrary, if general plan is micro-has down carried out when mobile for lift car 100, because signal 3S is conducting, signal 4 is for disconnecting, so be now judged as towards below and occurred skew.
In the time that lift car 100 has moved the small difference of height detection length M shown in Fig. 3, becoming the position-detection sensor 3 that only has shown in (d) is the state disconnecting.Therefore,, in the time position-detection sensor 3 being detected for off-state, system controller 108 sends and makes lift car 100 move the instruction that detects the corresponding distance of length M with small difference of height, again to carry out story height contraposition control.
By adopting structure as above, owing to the interval of the shape of tested drafting board 1 and position-detection sensor 2,3 and 4 being set as to make the output signal 5S of logical-arithmetic unit 5 can obtain identical output on all positions of hoist trunk with respect to the output signal 2S of position-detection sensor 2, region measuring ability and floor level can be opened and closed again to bit function so can realize elevator door simultaneously, thereby multifunction can be realized.In addition, even if the either party in each position-detection sensor has occurred fault, also can open and close region to elevator door and detect, therefore, error detection etc., can improve the redundancy of whole system including preventing.And, owing to being just set to 2 row at horizontal direction position-detection sensor and the detected plate portion thereof of hoist trunk, so can, in improving redundancy, realize the miniaturization of accommodation space, make also can install in limited small space.
Fig. 8 is the modification of the shape of tested drafting board 1 and the position of position-detection sensor 2,3 and 4, as shown in Figure 8, there is the tested drafting board 1 that is arranged on Room every bank 102, be arranged on accordingly the position-detection sensor 2,3 and 4 on lift car and the output signal 3S to position-detection sensor 3 and 4 and 4S with this tested drafting board 1 and compare and the logical-arithmetic unit 5 of computing.
The same with Fig. 5, the length that the shape of tested drafting board 1 is configured to the side that the Length Ratio position-detection sensor 3 and 4 of the side that the position-detection sensor 2 of lift car 100 moving directions passes through passes through is long, but top is formed smooth shape, make can not exceed the door 102 of Room door, thus, can eliminate in the time having there is earthquake etc. hoist cable etc. and hook the danger on tested drafting board 1 top.
Position-detection sensor 2 on the moving direction of lift car 100 with position-detection sensor 3 and 4 disalignments, be arranged on different listing, position-detection sensor 3 and 4 is coaxial setting.Can make the output signal 5S mode identical with the output signal 2S of position-detection sensor 2 of logical-arithmetic unit 5 determine the shape of tested drafting board 1 and the arrangement of position-detection sensor 2,3 and 4.
Fig. 9 shows the shape of tested drafting board 1 and the position of position-detection sensor 2,3 and 4, wherein, and length L 1 and the more small difference of height of bit function to be detected to length M be the size of predetermining for implementing floor level.The upper-lower position of position-detection sensor 2 is identical with the upper-lower position of position-detection sensor 4, and position-detection sensor 3 and the length y of 4 interval S and tested drafting board 1 are set to and make by logical-arithmetic unit 5, signal 3S to be carried out to computing with 4S and the OR output signal 5S that obtains equals can open and close the corresponding length in region with elevator door along with the movement of lift car 100.In addition, the length y of the side that the length L of the tested drafting board 1 of the side that position-detection sensor 2 passes through is passed through than position-detection sensor 3 and 4 is long, and difference is between the two x.Namely be set as L=x+y, x=s.And, length y is set at the floor of lift car and the height of floor from rail top of elevator lobby when consistent, the distance that position-detection sensor 3 and 4 lays respectively at the marginal portion from tested drafting board 1 of the inner side of tested drafting board 1 is the position that small difference of height detects length M, therefore y=S+2M.
Till that lift car 100 is accommodated to the variable condition of each signal of the floor that tested drafting board 1 is installed is identical with Fig. 7.
By adopting structure as above, compared with the occasion of Fig. 5, because the shape of tested drafting board 1 is formed the door 102 that can not exceed entrance hall, so in the time having there is earthquake etc., can not hook sensor et out of order and error detection etc. because of hoist cable etc.
