Concrete form of implementation
Followingly describe with reference to the form of implementation of accompanying drawing to apparatus of passenger conveyor of the present invention.
Fig. 1 is the structure skeleton diagram of a form of implementation of expression apparatus of passenger conveyor of the present invention, the instruction diagram of the velocity curve when Fig. 2 is the deceleration of apparatus of passenger conveyor.
As shown in Figure 1; in the apparatus of passenger conveyor of this form of implementation; electric power is presented to induction AC motor 14 with circuit breaker 11 and contactless switch contact 12 and converter plant 13 via protection from three-phase alternating-current supply 10, by making these induction AC motor 14 rotations apparatus of passenger conveyor is moved.And, export driving instruction 16 and deceleration instructions 17 from the control setup 15 of apparatus of passenger conveyor to converter plant 13, export breakdown signals 18 from converter plant 13 to control setup 15 simultaneously.In addition, safety device 19a, 19b, 19c, the total controlled relay 20 of 19d and vital circuit is connected in series respectively, and the safety device actuating signal of exporting from safety device 19a～19d 21 is admitted to control setup 15.And, have and not shown apparatus of passenger conveyor is carried out the mechanical brake of mechanical braking, and be used to control contactless switch contact 23a, 23b to electromagnetism winding 22 power supplies that discharge this mechanical brake.And then, have the speed detector 14a of the running velocity that detects apparatus of passenger conveyor.In addition, the contact 20a of the total controlled relay 20 of described vital circuit is arranged between control setup 15 and the converter plant 13.And, has rate selection switch 24, any speed in " low speed " this three retainings speed of " speed usually " of the speed operation that this rate selection switch for example can be arranged to the running velocity of apparatus of passenger conveyor " at a high speed " of the speed operation that divides with 40m/, divide with 30m/ and the speed operation that divides with 15m/.
At first, in apparatus of passenger conveyor, set running velocity with rate selection switch 24.The corresponding deceleration/decel of miles of relative movement when running velocity calculating that control setup 15 bases of apparatus of passenger conveyor set and predefined emergency braking.That is, when rate selection switch 24 was set at " at a high speed " with running velocity, the deceleration/decel when setting emergency braking made it meet projectile deceleration history shown in Figure 25.When rate selection switch 24 was set at running velocity " speed usually ", the deceleration/decel when setting emergency braking made it meet projectile deceleration history shown in Figure 26.And when rate selection switch 24 was set at " low speed " with running velocity, the deceleration/decel when setting emergency braking made it meet projectile deceleration history shown in Figure 27.
Below see figures.1.and.2, be set at the running velocity of apparatus of passenger conveyor with any safety device among safety device 19a～19d that " situation in when action is an example under " the state at a high speed, and the processing sequence of the apparatus of passenger conveyor of this form of implementation is described.
For example, after safety device 19a action, safety device actuating signal 21 is output in the control setup 15, and the total controlled relay 20 of vital circuit is disconnected simultaneously.Control setup 15 blocks the driving instruction 16 that sends to converter plant 13.And, when the contact 20a of the total controlled relay 20 of vital circuit is disconnected, stop the driving instruction 16 that sends to converter plant 13 too.Thus, the time point 4 set up at urgent stop condition of the apparatus of passenger conveyor that as shown in Figure 2, is in the normal operating condition 1 in " at a high speed " running velocity is transformed into by converter plant 13 and carries out braking maneuver according to retardation curve 5.That is,, control the output frequency/voltage of converter plant 13, make the rotative speed of induction motor (IM) 14 meet retardation curve 5 by sending deceleration instruction 17 to converter plant 13 from control setup 15.Afterwards, when running velocity that speed detector 14a detects apparatus of passenger conveyor has been reduced to speed below for example 3.0m/ divides, control setup 15 makes contactless switch contact 23a, 23b disconnects, thereby cut off mechanical brake apparatus is discharged the power supply of using electromagnetism winding 22, make the action of not shown mechanical brake, contactless switch contact 12 is disconnected, and cut off to the power supply of converter plant 13 with to the power supply of induction motor (IM) 14.Thus, mechanical brake carries out braking maneuver according to retardation curve shown in Figure 23, apparatus of passenger conveyor is stopped, and apparatus of passenger conveyor is remained on quiescence.
In the above description, situation when the running velocity with apparatus of passenger conveyor is set at " at a high speed " is that example is described, and be set at running velocity when carrying out emergency braking under the state of " usually speed ", common running state 2 beginnings from " speed usually " running velocity shown in Figure 2, brake according to retardation curve 6, be set at running velocity when carrying out emergency braking under the state of " low speed ", common running state 3 beginnings from " low speed " running velocity shown in Figure 2, brake according to retardation curve 7, no matter the running velocity of apparatus of passenger conveyor is set at " at a high speed ", on which the retaining speed in " speed usually " and " low speed ", all can when urgent operation, in predefined predetermined brake distance, apparatus of passenger conveyor be stopped.
In addition, calculate when realizing the required deceleration/decel of predefined predetermined brake distance according to the relevant running velocity of apparatus of passenger conveyor at control setup 15, when result of calculation has surpassed specified value because of certain reason, for example apparatus of passenger conveyor is to surpass the abnormal speed operation of " at a high speed " running velocity, when needing bigger deceleration/decel in order in the stopping distance of regulation, apparatus of passenger conveyor to be stopped, then control setup 15 does not allow converter plant 13 carry out braking maneuver, and make contactless switch contact 23a, 23b disconnects, cut-out discharges the power supply of using electromagnetism winding 22 to mechanical brake apparatus, make the mechanical brake action, contactless switch contact 12 is disconnected, to cut off to the power supply of converter plant 13 and to the power supply of induction motor (IM) 14.Thus, carry out braking maneuver, in predefined predetermined brake distance, apparatus of passenger conveyor is stopped by making mechanical brake.
According to this form of implementation, because can be according to the running velocity of apparatus of passenger conveyor, deceleration/decel with the best carries out emergency braking, so, even in the switchable type apparatus of passenger conveyor that can carry out many retaining switchings to running velocity, also can set certain value for begin till stop required stopping distance from emergency braking, the braking impulsive force that produces in the time of simultaneously can also be with emergency braking reduces to as far as possible little degree.In addition, calculating when realizing the required deceleration/decel of predefined predetermined brake distance according to the running velocity of apparatus of passenger conveyor by control setup 15, if judge when result of calculation has surpassed specified value, when promptly needing bigger deceleration/decel in order in the stopping distance of regulation, apparatus of passenger conveyor to be stopped, then switch so that allowing to give the mechanical brake apparatus of bigger braking force brakes, can in the stopping distance of predesignating, apparatus of passenger conveyor be stopped effectively thus.
And, in this form of implementation, adopt the running velocity of 24 pairs of apparatus of passenger conveyor of rate selection switch to select, but the present invention can certainly be applicable to the mode that adopts other, for example adopt software mode to set in the apparatus of passenger conveyor of running velocity.
