Embodiment
Illustrate embodiments of the present invention below with reference to accompanying drawing.
Fig. 1 is the system pie graph being monolithically fabricated for representing the present invention.In Fig. 1,1 be elevator car, have driving electricity
The motor 2 of ladder and the counterweight 3 for being arranged on the position opposed with car, they are linked respectively via pulley 4 and hoist cable 5.
In addition, installing encoder 6 in motor 2, carried out by the rotation corresponding to motor 2 and the pulse of caused encoder 6
The position detection of elevator.There is the governor sheave 7 for linking and rotating with the car of elevator in addition, install and adjust in governor sheave 7
Fast device encoder 8, using the rotation corresponding to governor sheave 7, the pulse of caused speed regulator encoder 8, can equally be detected
The position of elevator.In addition, installing shield 9a, 9b, 9c in tower, installed in car 1 and pass through each shield for detecting elevator
Position detecting device (PosiTector) 10a, 10b, 10c of this case.Here, shield 9a is arranged on the elevator of each floor
Door sets position, in the case where 10a is blocked, knows that car is located at the elevator door setting position of which floor.Sometimes should
Shield 9a is especially labeled as area's shield.On shield 9b and 9c, the elevator door of each floor set position and
There is no fast running area of elevator door etc. with given interval setting yet.It is transfused in control device 11 installed in motor 2
Encoder 6 pulse information, position and the speed of elevator can be detected, and then can be examined from position detecting device 10b signal
Ce Men areas and shield 9b input state.In safety governor 12, the pulse signal of speed regulator encoder 8 can be used to examine
Position and the speed of elevator are surveyed, and then can be from position detecting device 10c signal detection shield 9c input state.
Fig. 2 is the block diagram of control device 11 and safety governor 12.Safety governor 12, which possesses, to be used for and multiple positions
The I/O interface 16 and MPU13 that detector 10c, speed regulator encoder 8, control device 11 connect.MPU13 possesses position detection part
14 and position recover processing unit 15.The position data that the position detection part 14 is created uses the tune for being arranged on governor sheave 7
The pulse signal of fast device encoder 8 creates positional information.Thus, the influence slided caused by emergent stopping is compiled with motor
Code device is almost consistent with the elevator position of reality compared to considerably less.Recover processing unit 15 and received from position sensor 10C in position
During to signal, the absolute position of position car 1 can be grasped.Thus, if elevator emergency stops, afterwards in the failure of no equipment etc.
In the case of started running with low speed, then receive the input signal from position detecting device 10c, according to the position of speed regulator encoder
The shield 9c that confidence ceases to determine to detect, the position that processing unit 15 grasp car 1 can be recovered by position.Here, with advance
Premised on absolute position when how to determine input position detection means 10c.For example, in advance by each shield 9c positions
Non-volatile storage Jie (not shown) is stored in which floor or positioned at which floor gap, positioned at position of several meters away from ground
Matter.Due in each shield 9c itself and not containing its height and the information of position, therefore detected in position detecting device 10c
The Position Approximate that processing unit 15 grasps car 1 with speed regulator encoder is recovered in shield 9c opportunity, position, it is determined that from the position
The shield 9c detected is arranged on which position in liftway.If it is determined that shield, then processing unit 15 is recovered in position
It is based on being stored in the positional information of the shield of non-volatile memory medium etc. to determine the absolute position of car 1.In safety
When controller 12 completes the grasp of position, IO of the safety governor from I/O interface 16 via communication line 17 into control device 11
Interface 18 sends position data.
Next, control device 11 possesses I/O interface 18 and MPU19.MPU19 possesses：Position detection part 20, the detection of door area
Portion 21, speed instruction department 22 and halt instruction portion 23.Position detection part 20 is based on from the position that safety governor 12 receives
Data recover position data.Door area test section 21 determines whether to detect an area shield 9a.With safety governor 11
Position detection part 15 is handled this case that perceive 9c for condition to carry out the recovery of position data, but sets position in elevator door
And there is car in fast running area of no elevator door etc. in the case of detecting shield 9c, to perceive less than 9a.It is being not provided with
In the case of door area shield 9a, in the case of being fast running area, elevator is made to running at high speed from speedup instruction department 22
Cross.After being transitioned into and running at high speed, if stopping processing unit 23 as generally without door area is differently detected with common traveling
Stop like that and terminate to operate.In addition, if an area shield 9a is also provided with the position same with shield 9c, in MPU19
Nei Men areas test section 21 detects an area, stops elevator like this.Due to when elevator emergency stops, in control device 11
The middle pulse signal using the motor encoder 6 for being arranged on motor 2 creates position, therefore caused by emergent stopping
Hoist cable 5 slip and produce position data and the difference of actual car position.By as in this embodiment with safety control
Device processed uses the encoder of governor sheave, can correctly judge position.
Fig. 3 represents that elevator of the emergent stopping outside door area recovers position data after starting running and be transitioned into what is run at high speed
The flow chart of operating.Emergent stopping (S1) occurs in running at high speed for elevator.After emergent stopping generation, the speed of elevator turns into
0(S2).When control device 11 detects that elevator stops at this case outside an area, Xiang Menqu is started running (S3) with low speed.
In safety governor detection shield 9c (S4).Determine it is which shield 9c based on the positional information of speed regulator encoder,
The positional information of shield based on determination, recover the position data (S5) of elevator in safety governor.Safety governor 12 will
Position data is sent to control device, and control device makes position data recover (S6).Control device 11 confirms there is screening when recovering
Whether the position of shield plate detects an area shield 9a (S7).In the case where being to detect an area shield 9a position, stop
Only terminate operating (S10).Control device 11 does not stop in the case where not detecting an area shield 9a and continues to travel,
Detection is no longer checked and accepted this case that shield 9b, i.e. test position detector 10b, which turns into, closes this case (S8).Controlled hiding
When device 11 processed detects that position sensor 10b turns into closing this case, elevator is set to start speedup (S9) to door area.Control dress
11 are put when detecting that an area shield 9a, confirmation are arrived in a this case that area, stops and terminates to operate (S10).
So in the present embodiment, in the case where elevator emergency stops at fast running area, can also restart in elevator
In the case of restart to travel, with the information creating elevator car from the encoder installed in governor sheave axle can be passed through
The safety governor of railway carriage or compartment position data and the shield for the position detection for being arranged on liftway determine the sedan-chair after emergent stopping
The absolute position in railway carriage or compartment, thus can also elevator be set to be run at high speed outside door area.
