First, in fig. 3 a, in section 1, brake current-order i*Zero state, brake torque T be in order to Fetter pulley and output the state of enough moments of torsion, car speed V is zero.
Section 2 is to make brake current-order i*Stepped increased state, accompany with this, flowed in solenoid coil Brake electric current i also increase.Here, brake current-order i is made*(or the increased purposes of brake electric current i), it is to pass through Brake electric current i increases are made to make so as to weaken the brake torque T of the brake force as brake from car 104 and balance weight The brake force of 106 unbalance caused moment of torsion and brake 102 turns into poised state.In section 2, with brake electric current i Increase, produce electromagnetic force in solenoid coil, turn into the action that brake torque T is weakened, but because the state is system Dynamic device torque T be more than from car 104 and balance weight 106 it is unbalance caused by moment of torsion state, so car 104 is motionless and car Speed V holdings zero are constant.In addition, now make brake current-order i*Change stepwise, be because it is contemplated that brake 102 Response.
Section 3 shows to secure brake current-order i in the timing for detecting car speed V*State.Detect sedan-chair Railway carriage or compartment speed V, show that brake torque T becomes less than the state of the unbalance caused moment of torsion from car 104 and balance weight 106. Now pass through fixed brake current-order i*, so as to the brake force by being used as brake 102 brake torque T with From the difference of car 104 and the unbalance caused moment of torsion of balance weight 106, to establish the state of the acceleration of car 104.
In section 4, because detected car speed V has exceeded target car speed V*, thus make brake electric Stream instruction i*Reduce, reduce the car speed V of car 104.
Section 5 shows to make reduced brake current-order i once*From the value reduced again increased state. In this case, because car speed V drops to substantially zero for the time being, after second, untill the setting in motion of car 104 Need the more time.The phenomenon easily occurs in the case of the slower brake of response of the magnetic flux to curent change, by This needs the more time untill passenger is rescued, and passenger is felt uneasy.
Next, Fig. 3 b the 1st control method is illustrated.Untill section 1~3, the 1st control method substantially with Fig. 3 a control method is identical.
In section 4, in the case of Fig. 3 a control method, from brake current-order i*Zero value is dropped to for the time being Rise, make brake current-order i again*Increase steppedly.On the other hand, will be in the sedan-chair of section 3 in the 1st control method Brake current-order i during 104 setting in motion of railway carriage or compartment one time*Information-storing device 34, the car speed in section 4 are arrived in keeping in advance The timing of V vanishing, by brake current-order i*Control and refer to for the brake electric current taken care of in advance in information-storing device 34 Make value.In section 5, by brake current-order i*It is set as the brake current-order taken care of in advance in information-storing device 34 Value, reduces afterwards.Accordingly, in section 5, the time untill the setting in motion of car 104 after second can be shortened, can Realize rescuing as early as possible for passenger.
Next, Fig. 4 a the 2nd control method is illustrated.Untill section 1~3, the 2nd control method substantially with 1st control method is identical.
In the 2nd control method, by the brake current-order i in 3 car of section, 104 setting in motion one time*In advance Information-storing device 34 is arrived in keeping, and car speed V is less than parameter such as target car speed V in section 4*Timing, will make Dynamic device current-order i*Control the brake current instruction value to be taken care of in advance in information-storing device 34.In section 5, it will make Dynamic device current-order i*It is set as the brake current instruction value taken care of in advance in information-storing device 34, reduces afterwards.In the feelings Under condition, in section 5, car 104 is in the state of motion, is opened so can further shorten the car 104 after second Time untill beginning to move, rescuing as early as possible for passenger can be realized.
Next, Fig. 4 b the 3rd control method is illustrated.Untill section 1~3, the 3rd control method substantially with 1st control method is identical.
In the 3rd control method, by the brake current-order i in 3 car of section, 104 setting in motion one time*In advance Information-storing device 34 is arrived in keeping, is less than parameter such as target car speed V in car speed V in section 4*Timing, will brake Device current-order i*Control the brake current instruction value to be taken care of in advance in information-storing device 34.In section 5, it will brake Device current-order i*It is set as the brake current instruction value taken care of in advance in information-storing device 34, afterwards, periodically increases Reduce afterwards.In this case, in section 5, car 104 is in the state of motion, so can further shorten second Time after secondary untill the setting in motion of car 104, rescuing as early as possible for passenger can be realized.
Fig. 5 is the block diagram for the control system for showing brake current-order.In Figure 5, the control of brake current-order System by ASR (speed control), the ACR (current controller) 503 of control brake electric current, brake coil model 504, Model 505, brake current-order generating unit 506, brake current-order maintaining part 507 and the car speed of brake main body The grade of detector 508 is formed.In addition, in the present embodiment, open input speed instruction V*Switch 501, break from control loop ASR (speed control) 502 is opened.
Car speed detector 508 inputs car speed (Vre) 509, detects the car speed of car 104, and detection is tied Fruit is output to brake current-order generating unit 506 and brake current-order maintaining part 507.Brake current-order generating unit 506 generate brake current-order (brake current instruction value), and the brake electric current that will be generated according to car speed Instruction is output to brake current-order maintaining part 507.When car 104 is started to move by brake current-order maintaining part 507 Brake current instruction value keeping arrive information-storing device 34, will be in information-storing device 34 in 104 next setting in motion of car Middle taken care of brake current instruction value is output to current controller 503 as brake current-order.Accordingly, in car During 104 next setting in motion, the brake electricity with being taken care of in information-storing device 34 is flowed into model (brake main body) 505 Flow the corresponding brake electric current of command value.
Fig. 6 is the flow chart for illustrating the generation processing of brake current-order.Hereinafter, brake is illustrated using Fig. 6 The specific action of current-order generation processing 32.
First, braking force control portion 20 opens according to the result for rescuing operation start processing 30 to judge to rescue operating Beginning instruction is ON (beginning) or OFF (stopping) (step S101), when it is OFF to rescue operation start instruction, end processing, Operation start instruction is rescued when being ON, is transferred to step S102 processing.Here, on rescuing operation start instruction as ON's Condition, generally carry out in the case where passenger is trapped in car and motor etc. can not be driven due to some abnormal etc. Setting.In addition, as operation condition now, it is also desirable to which brake 102 is operating normally.Turn on rescuing operation start instruction OFF condition, in usual operating or implementation is rescued when reaching the position that can be opened the door of nearest floor in operation process Set.In addition it is also possible to manually set ON (beginning)/OFF (stopping).
Next, braking force control portion 20 judges whether car speed V is zero (step S102), is zero in car speed V In the case of, whether car 104 is in halted state by brake 102, it is determined that being situation that car moves for the first time (step S103).In the case of car 104 for the first time motion, by making brake electric current i increases now be used as system to weaken The brake torque T of the brake force of dynamic device 102, in order that from car 104 and the unbalance and caused moment of torsion of balance weight 106 with making The brake force of dynamic device 102 is in poised state, and braking force control portion 20 makes brake current-order (current-order) i*Increase (step Rapid S105), terminate the processing of the routine (routine).
On the other hand, in step s 103, in the case of after the motion of car 104 is for the second time, braking force control portion The brake current instruction value (current value) taken care of in information-storing device 34 setting is arrived brake current-order (electric current by 20 Instruction) i*(step S104).In addition, keeping describes to the timing of information-storing device 34 below in step S108.Afterwards, brake Power control unit 20 makes brake current-order (current-order) i*Increase (step S105) from set current instruction value, terminate Processing under the routine.According to the resolution ratio of control brake 102, to determine to make brake current-order i*Increased value.
On the other hand, in step S102, in the case that car speed V is not zero, i.e. be on the move in car 104 In the case of, braking force control portion 20 is by brake current-order (current-order) i*Fixed (S106).Now, by car speed It is not that brake current-order i is fixed under zero situation to spend V*, so as to which brake 102 will not be discharged completely, it can be ensured that braking Piece and the state of pulley friction.
Next, braking force control portion 20 judges whether car 104 is first motion (step S107), at the beginning of car 104 In the case of secondary motion, (the step of information-storing device 34 is arrived into brake current instruction value (current instruction value) keeping when moving S108), afterwards, it is transferred to step S109 processing.
Braking force control portion 20 be determined as in step s 107 the motion of car 104 be not first in the case of or in step After rapid S109 processing, judge whether car speed V is more than target car speed V*(step S109).In addition, target car Speed V*, generally to safeguard running speed or the speed lower than safeguarding running speed is set, but can also be set as specified Speed.
In step S109, it is more than target car speed V in car speed V*In the case of, braking force control portion 20 in order to Car 104 is slowed down by brake torque, make brake current-order i*Reduce (step S110), terminate the place under the routine Reason.
