Concrete form of implementation
Followingly describe with reference to the form of implementation of accompanying drawing to apparatus of passenger conveyor involved in the present invention.
Fig. 1 is the summary pie graph of a form of implementation of expression apparatus of passenger conveyor of the present invention, and the instruction diagram of the velocity curve when Fig. 2 is the apparatus of passenger conveyor deceleration, Fig. 3 are A enlarged drawings partly shown in Figure 2.
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 this induction AC motor 14 is rotated 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, and export breakdown signals 18 to control setup 15 from converter plant 13.In addition, the total controlled relay 20 of safety device 19a, 19b, 19c, 19d and vital circuit is connected in series respectively, and the safety device actuating signal of exporting from safety device 19a～19d 21 is imported into 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 that detects the apparatus of passenger conveyor running velocity.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.
Below referring to figs. 1 through Fig. 3, be example with any safety device among safety device 19a～19d in the situation that apparatus of passenger conveyor is in service when having carried out action, 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 cut off, block the driving instruction 16 that sends to converter plant 13 too.Thus, as shown in Figure 2, the time point 2 that the apparatus of passenger conveyor that is in normal operating condition 1 is set up at urgent stop condition is transformed into by converter plant 13 and carries out braking maneuver according to predefined regulation retardation curve 3.This state-transition, as shown in Figure 3, be for from normal operating condition 1 during the state-transition of carrying out braking maneuver by converter plant 13, by realizing the velocity variations 8 of quadratic curve shape, suppress rapid velocity variations, with the variation of the human discomfort that alleviates the passenger, uneasy sense and body gesture.That is,, control the output frequency and the output voltage of converter plant 13, make the rotative speed of induction motor (IM) 14 meet retardation curve 3 by sending deceleration instruction 17 to converter plant 13 from control setup 15.Afterwards, if speed detector 14a detects the running velocity of apparatus of passenger conveyor and has been reduced to for example 3.0m/ timesharing, control setup 15 disconnects contactless switch contact 23a, 23b, thereby cut off mechanical brake apparatus is discharged the power supply of using electromagnetism winding 22, make not shown mechanical brake action, contactless switch contact 12 is disconnected, to 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.
Below, the supervision of the error state of passenger's drive apparatus braking is described.In the apparatus of passenger conveyor of this form of implementation, preestablish above-mentioned retardation curve 3 and guard condition velocity curve 5.It is that stack allows change velocity contrast 4 and the curve that forms on the running velocity curve in retardation curve 3.And, because converter plant 13 or control setup 15 takes place unusually etc., and cause deceleration instruction 17 can't normal delivery the time, can consider not deceleration/decel, and with other deceleration/decels, the deceleration/decel when for example speed is switched slows down with retardation curve 3.After slowing down with this deceleration/decel, shown in the dotted portion of Fig. 2, the retardation curve 7 of apparatus of passenger conveyor forms the state that intersects with guard condition velocity curve 5, at this moment, the velocity anomaly state has appearred in control setup 15 judgements, and measures time point 6 with this time point as velocity anomaly.Corresponding therewith, control setup 15 disconnects contactless switch contact 23a, 23b, thereby cut off mechanical brake apparatus is discharged the power supply of using electromagnetism winding 22, make the mechanical brake action, contactless switch contact 12 is disconnected, to cut off to the power supply of converter plant 13 with to the power supply of induction motor (IM) 14.Thus, make mechanical brake carry out braking maneuver, apparatus of passenger conveyor is stopped in predefined miles of relative movement, and apparatus of passenger conveyor is remained on quiescence according to retardation curve shown in Figure 27.And guard condition velocity curve 5 is set in the scope that satisfies by the appearance of regulations such as relevant laws and regulations the emergency stopping distance when unusual.
And, when carrying out speed-down action near the speed of guard condition velocity curve 5, may occur arriving that higher limit with emergency stopping distance is close apart from this state, so, according to signal from speed detector 14a output, the time point of setting up from the urgent stop condition of apparatus of passenger conveyor of safety device 19a～19d action etc. 2, in control setup 15, carry out cumulative calculation, to calculate lasting operating range, and when the lasting operating range of calculating has surpassed certain value, it is unusual that emergency stopping distance has appearred in judgement, thereby make contactless switch contact 23a, 23b disconnects, and to cut off mechanical brake apparatus is discharged the power supply of using electromagnetism winding 22, makes the mechanical brake action, contactless switch contact 12 is disconnected, to cut off to the power supply of converter plant 13 with to the power supply of induction motor (IM) 14.Thus, make mechanical brake carry out braking maneuver, apparatus of passenger conveyor is stopped in predefined miles of relative movement.
And, occur unusual and cause control setup 15 normally under the state of recognition speed information at speed detector 14a for example, when if the urgent stop condition of apparatus of passenger conveyor of safety device 19a～19d action etc. is set up, then do not allow converter plant 13 carry out braking maneuver, and the time point of setting up at urgent stop condition 2, make contactless switch contact 23a by control setup 15,23b disconnects, to cut off mechanical brake apparatus is discharged the power supply of using electromagnetism winding 22, make the mechanical brake action, contactless switch contact 12 is disconnected, to cut off to the power supply of converter plant 13 with to the power supply of induction motor (IM) 14.Thus, make mechanical brake carry out braking maneuver, apparatus of passenger conveyor is stopped according to retardation curve shown in Figure 23.And, take place unusual at converter plant 13, when breakdown signal 18 outputs to control setup 15, also carry out identical processing, promptly, do not allow converter plant 13 carry out braking maneuver, and the time point of setting up at urgent stop condition 2, by control setup 15 contactless switch contact 23a, 23b are disconnected, to cut off mechanical brake apparatus is discharged the power supply of using electromagnetism winding 22, make mechanical brake action, contactless switch contact 12 is disconnected, to cut off to the power supply of converter plant 13 with to the power supply of induction motor (IM) 14.Thus, make mechanical brake carry out braking maneuver, apparatus of passenger conveyor is stopped according to retardation curve shown in Figure 23.
According to this form of implementation, because regardless of the size cases of loading, all can in predefined stopping distance, apparatus of passenger conveyor be stopped where necessary,, can improve safety so the performance of apparatus of passenger conveyor is satisfied effectively by the relevant laws and regulations governing criterion.And,, also can replenish foot, so can in predefined stopping distance, apparatus of passenger conveyor be stopped by mechanical brake even former thereby when causing the braking of converter plant insufficient because of some.And, to switch to running velocity that the switching timing of carrying out braking maneuver by mechanical brake apparatus is set in apparatus of passenger conveyor and reach 1.0～4.0m/ and divide this constantly from carry out braking maneuver by converter plant, thus, then not only can brake apparatus of passenger conveyor effectively, but also apparatus of passenger conveyor is stopped in predefined stopping distance by converter plant.
And, the contact 20a that the action of safety device 19a～19d is carried out the total controlled relay 20 of vital circuit of master control partly is set by the driving instruction at converter plant, driving instruction is blocked in action with the response safety device, can effectively apparatus of passenger conveyor be switched to braking mode when safety device moves.And, by velocity curve is set, make and be the quadratic curve shape changing the velocity curve that is converted to when carrying out braking maneuver from normal operating condition by converter plant 13, braking maneuver is carried out smoothly, can alleviate human discomfort and uneasy sense that braking maneuver causes the passenger thus, the attitude change with the passenger is controlled at Min. simultaneously.And, when speed detector 14a takes place can't obtain the velocity information of apparatus of passenger conveyor unusually, the braking maneuver that control setup 15 is carried out converter plant 13 lost efficacy, and make mechanical brake apparatus carry out braking maneuver, thus, apparatus of passenger conveyor is stopped in predefined stopping distance.
