Under the situation that enters into step S7, relatively control part 30 carries out the detection of 3 rotation directions in the drive division.Particularly, relatively control part 30 is according to the phase place of impulse singla pls-s1 with the impulse singla pls-s2 of detector 72b of the detector 72a of pedal speed detector 7, the rotation direction of detection pedal.
In addition, relatively control part 30 is according to the phase place of impulse singla pls-hr1 with the impulse singla pls-hr2 of detector 24b (R) of the detector 24a (R) of the handrail speed detector 20 on right side, the rotation direction of the handrail on detection right side.Similarly, relatively control part 30 is according to the phase place of impulse singla pls-hl1 with the impulse singla pls-hl2 of detector 24b (L) of the detector 24a (L) of the handrail speed detector 20 in left side, the rotation direction of the handrail on the left of detecting.
Next, in step S8, relatively control part 30 judges whether the rotation direction of handrail in the rotation direction of handrail on rotation direction, right side of pedal and left side is identical.And relatively control part 30 enters into step S9 under the situation that is judged as the rotation direction unanimity, is being judged as under the inconsistent situation of rotation direction, is judged as and has produced heavy fault, enters into step S17 described later.
Under the situation that enters into step S9, relatively control part 30 carries out velocity correction and handles in processing after this.In this velocity correction is handled, at first, carry out handling with the velocity correction of the comparison of the speed of the handrail on right side based on the speed of pedal, next, carry out velocity correction processing based on the comparison of the speed of the handrail in the speed of pedal and left side.Wherein, be simplified illustration, in the flow process of Fig. 8, only illustrate based on the velocity correction of the comparison of the speed of the handrail on the speed of pedal and right side and handle.Below, this velocity correction processing is elaborated.
In step S9, relatively control part 30 judges that the difference of handrail speed Vhr1 on pedal speed Vs1 and right side is whether in the setting value ± Δ V (being equivalent to the 1st permissible range) that stipulates.And relatively control part 30 enters into step S10 under the situation that is judged as the condition that satisfies step S9, under the situation that is judged as the condition that does not satisfy step S9, enters into step S14.
Under the situation that enters into step S10, relatively control part 30 generates the instruction speed Vr of the handrail on right side according to following formula (1).In addition, under the situation of the instruction speed Vl of the handrail on the left of obtaining, use following formula (2).
Vr＝Vs1+(Vs1-Vhr1) (1)
Vl＝Vs1+(Vs1-Vhl1) (2)
Relatively control part 30 makes pedal consistent with the speed of handrail by providing the new instruction speed of obtaining like this (speed value after being equivalent to proofread and correct) to speed variable 33 (R), 33 (L), being controlled to.
Next, unspecified step S11～S18 is still described.
Entering into from step S2 under the situation of step S11, relatively control part 30 judges whether the difference of pedal speed Vs1 and Vs2 has not continued with interior state more than specified time t1 (being equivalent to the 1st specified time) second at the setting value ± Δ Vs of regulation.And, be not judged as under the situation that continues (that is, returning in the setting value ± Δ Vs of regulation) in difference through specified time t1 front running board speed Vs1 and Vs2, relatively control part 30 carries out the later processing of above-mentioned steps S3.On the other hand, be judged as under the situation of continuation, be judged as and produced heavy fault, entering into aftermentioned step S17.
Next, entering into from step S4 under the situation of step S12, relatively control part 30 judges whether the handrail speed Vhr1 on right side and the difference of Vhr2 have not continued with interior state more than specified time t2 (being equivalent to the 2nd specified time) second at the setting value ± Δ Vh of regulation.And, be not judged as under the situation that continues (that is, returning in the setting value ± Δ Vh of regulation) through the handrail speed Vhr1 on the preceding right side of specified time t2 and the difference of Vhr2, relatively control part 30 carries out the later processing of above-mentioned steps S5.On the other hand, be judged as under the situation of continuation, be judged as and produced heavy fault, entering into aftermentioned step S17.
Next, entering into from step S6 under the situation of step S13, relatively control part 30 judges whether the handrail speed Vhl1 in left side and the difference of Vhl2 have not continued with interior state more than specified time t3 (being equivalent to the 2nd specified time) second at the setting value ± Δ Vh of regulation.And, be not judged as under the situation that continues (that is, the handrail speed Vhl1 in left side and the difference of Vhl2 return in the setting value ± Δ Vh of regulation before through specified time t3), relatively control part 30 carries out the later processing of above-mentioned steps S7.On the other hand, be judged as under the situation of continuation, be judged as and produce heavy fault, entering into aftermentioned step S17.
Next, entering into from step S9 under the situation of step S14, relatively control part 30 judges that the difference of handrail speed Vhr1 on pedal speed Vs1 and right side is whether in the setting value ± Δ Ve (being equivalent to the 2nd permissible range) that stipulates.And relatively control part 30 is judged as and has produced light fault under the situation that is judged as the condition that satisfies step S14, enters into step S15, under the situation that is judged as the condition that does not satisfy step S14, is judged as and has produced heavy fault, enters into step S17.
Herein, as Δ Ve, set than the big value of in the judgement of step S9, using of Δ V.And, in control part 30 relatively,, difference transfers to the processing of step S15, S16 if in ± Δ Ve, then being judged as light fault, if difference has surpassed ± Δ Ve, then judge the processing of attaching most importance to fault and transferring to step S17, S18.
Under the situation that enters into step S15, relatively the handrail speed on control part 30 generation notice pedals and right side is the unusual alarm L of light fault.In addition, relatively control part 30 is shown to passenger conveyors self with this alarm L, and sends to servicing center (not shown) as alarm signal.And then relatively control part 30 generates pedal speed Vs1 as the handrail speed command value Vr on right side in step S16.
Next, enter under the situation of step S17 at some from step S11, S12, S13, S14, relatively control part 30 produces heavily failure warning H and unusual as the detection of pedal speed.In addition, relatively control part 30 is shown to passenger conveyors self with this alarm H, and sends to servicing center (not shown) as alarm signal.And then in step S18, relatively control part 30 stops pedal and handrail.
The comparison process of above-mentioned steps S9, S14, at first, according to relatively carrying out of the speed of the handrail on the speed of pedal and right side, next, according to relatively carrying out of the speed of the handrail in the speed of pedal and left side.And, according to judged result based on each comparison process, the velocity correction processing of execution in step S10, S16, the alarm of step S15, S17 handle and step S18 stop to handle.
Like this, the handrail driving control device in the present embodiment 1 uses 2 detectors to obtain each speed of pedal, right armrest, left side handrail respectively.Like this, by each detector is made as redundancy structure, whether the detection speed that can judge rightly is normal.Its result can not produce owing to the unusual handrail speed that causes of speed detection of pedal speed detector 7 is unusual, and the speed that also can not produce owing to handrail speed detector 20 detects the unusual handrail speed correction that causes unusually.That is, can prevent the state of passenger conveyors 1 action under pedal speed and the inconsistent state of handrail speed.
In addition, by each detector is made as redundancy structure, can detect the rotation direction (hand of rotation) of pedal 2 and handrail 10 respectively.Its result can also prevent the state that pedal 2 and handrail 10 turn round on reversing sense with identical speed.
In addition, possess can with the regulation setting value ± Δ V be set at handrail speed the correction boundary value, with the regulation setting value ± Δ Ve be made as the pedal speed of passenger conveyors and the deviation limits value of handrail speed, carry out the structure of the comparison judgment processing in 2 stages.Its result, the difference of pedal speed and handrail speed not setting value ± Δ V with interior situation under, can survey the travel light fault state of load of imaginary above handrail that produced.And, if, then can arouse passenger's attention because the load that the passenger causes increases.And then, if continue to produce this warning, then it is also conceivable that the unusual of handrail driving system, so progress chart (schedule) that can the schedule maintenance operation.
In addition, if the difference of pedal speed and handrail speed not setting value ± Δ Ve with interior situation under, ground same, passenger on the passenger conveyors might fall, so judge the fault of attaching most importance to, passenger conveyors stopped, thereby can prevent that the passenger from falling.Thus, the phenomenon that passenger conveyors moves in the inconsistent mode of the speed of pedal and handrail can not appear, so can prevent that the passenger from falling.
As mentioned above,, possess, can implement the structure that velocity correction processing, alarm are handled, stopped to handle reliably by each speed detector is made as redundancy structure according to embodiment 1.Its result can access and can detect pedal speed and the not synchronous state of handrail speed reliably, carries out the handrail driving control device with the cooresponding suitable processing of velocity deviation.And then, can distinguish and judge light fault, heavy fault according to the comparison judged result of having used 2 kinds of setting values, can carry out and the cooresponding suitable processing of faulty condition.
In addition, handrail driving control device of the present invention can also be applicable to about be provided with the situation of many handrail driving machines.Fig. 9 be in the handrail driving control device that is illustrated in the embodiments of the present invention 1 about have the figure of the configuration under the situation of many handrail driving devices.Even as shown in Figure 9, about be provided with under the situation of many handrail driving machines, also can use handrail driving control device of the present invention, can obtain same effect.
