The specific embodiment
Below, use accompanying drawing that one embodiment of the safety device of passenger conveying equipment of the present invention is described.Fig. 1 has represented the downside end of passenger conveying equipment 40 with block diagram.With about 44 on the railing that forms of handrail 42 below, disposed with ring-type bonded assembly pedal 1.At this above pedal 1 and on the arcuation face of front side, be formed with a plurality of parallel grooves and comb teeth 22 that can projection.Overlapping and disposed floor, gangway 2 with pedal 1 part in the mode of level.On floor, gangway 2, also be formed with a plurality of parallel grooves and comb teeth 22 that can projection.Floor, gangway 2 is static, and disposes main frame 46 on the Width end.Also disposed floor, gangway support beam 3, this floor, gangway support beam 3 is vertical with this guiding parts 46, and two ends are remained on the main frame 46.Floor, gangway support beam 3 is supporting floor, gangway 2.
The face of the front side of floor, gangway support beam 3 has planar portions, and acceleration transducer unit 4 is installed on this planar portions.In addition, in this Fig. 1,, also can be installed on the floor, gangway 2 by degree of will speed up sensor unit 4 though on floor, gangway support beam 3, acceleration transducer unit 4 has been installed.Acceleration signal by acceleration transducer unit 4 detects is directed to control setup 5 via wiring.Control setup 5 has: be used for selecting the not shown filter of the signal of expectation, the signal that is leached by this filter being carried out the operational part 6 and the control part 7 of Integral Processing from acceleration transducer unit 4 detected signals; Wherein, control part 7, integrated value that operational part 6 is calculated and pre-set threshold compare judges have no abnormally, having when unusual, stops passenger conveying equipment 40 or makes its low-speed running.As shown in Figure 1, acceleration transducer unit 4 be set at two side ends, floor, gangway support beam 3 or this floor, gangway support beam 3 on floor, gangway 2 rear side, floor, gangway 2 below, can detect the acceleration/accel of the direct of travel of pedal 1.
Below, the action according to the safety device 50 of the present embodiment of above-mentioned formation is described.When on 1 on the pedal of passenger conveying equipment 40 or pedal 1 and 2 on floor, gangway foreign matter taking place and stop up, the collision phenomenon that is produced by foreign matter can take place on pedal 1 and 2 on floor, gangway.Because this collision can produce the acceleration/accel with big composition on the direct of travel of pedal 1.This acceleration/accel transmits to floor, gangway 2 and floor, gangway support beam 3.So, be configured on the direct of travel of pedal 1 and have the acceleration transducer unit 4 of sensitivity.The chatter phenomena on the floor, gangway 2 in the time of thus, can grasping direct impact.
In addition, in order to make circulation driving brief acceleration sensor unit 4 not produce interference with pedal 1 at pedal 1, below the side, front or floor, gangway 2 of floor, gangway support beam 3, near the back side configuration acceleration transducer unit 4 of floor, gangway support beam 3.Thus, though pedal 1 circulation, not with the acceleration transducer unit case of collision under, can prevent the damage of acceleration transducer unit 4.In Fig. 1, though be provided with the acceleration transducer unit 4 that on the direct of travel of pedal 1, has sensitivity in the side, front of floor, gangway support beam 3, but, then can be more reliably will stop up and the floor, gangway 2 that takes place and the collision phenomenon of pedal 1 separate with other phenomenon by foreign matter if the acceleration transducer unit 4 that will have a sensitivity of vertical is configured in the following etc. of floor, gangway 2 for example.
That is, if on the floor, gangway the 2 enterprising Chang Buhang that work, then have the output of acceleration transducer unit 4 of the sensitivity of vertical, bigger than the output of the acceleration transducer unit 4 that on the direct of travel of pedal 1, has sensitivity.Stop up if foreign matter takes place, the output that then has the acceleration transducer unit 4 of sensitivity on the direct of travel of pedal 1 becomes bigger than the output of the acceleration transducer unit 4 that has sensitivity on vertical.So, because at acceleration transducer unit 4 that has sensitivity on the vertical and the output relation that has the acceleration transducer unit of sensitivity on the direct of travel of pedal 1 is inverse relationship, so, can specificly stop up and the floor, gangway 2 of generation and the collision phenomenon of pedal 1 by foreign matter.
Fig. 2 has represented the installation portion of acceleration transducer unit 4 in detail with block diagram.On acceleration transducer unit 4, substrate 9 is provided with acceleration/accel IC sheet 8.On 4 angles of substrate 9, on being made into a side (right flank among the figure) of rectangular-shaped mounting blocks 10, being fastenedly connected parts 11A～11D by substrate and being fastenedly connected.On mounting blocks 10, have hole from the perforation of side, front to the depths, the piece that inserts in this hole is fastenedly connected parts 12A, 12B mounting blocks 10 is fixed on floor, the gangway support beam 3.
According to present embodiment, even the passenger conveying equipment that has been provided with and has used also can only append by simple construction acceleration transducer unit 4 is set.In addition, when appending the acceleration pick-up of the acceleration/accel that is used to detect vertical, in the side of the mounting blocks 10 that is not used, for example on the side in the left side, become the mode installation base plate 9 of longitudinal direction and acceleration/accel IC sheet 8 is installed on substrate 9 according to the acceleration detection direction and get final product.In the present embodiment, though combination acceleration/accel IC sheet 8 and substrate 9 and constitute acceleration transducer unit 4, the detection of acceleration/accel not necessarily is defined in the IC sheet.In a word, as long as can detect the direct of travel of pedal 1 or the acceleration/accel of vertical.
Be fastenedly connected between substrate 9 and the mounting blocks 10 and be fastenedly connected parts 12A, 12B and be fastenedly connected between mounting blocks 10 and floor, the gangway support beam 3 though be fastenedly connected parts 11A～11D, also can replace and use these to be fastenedly connected mechanism and to use bonding grade to be fastenedly connected method by piece by substrate.Say nothing of, also can substrate 9 be set directly on floor, gangway 2 or floor, the gangway support beam 3 by mounting blocks 10.
Fig. 3 has represented other embodiment of acceleration transducer unit 4 in detail with block diagram.In the embodiment shown in Figure 2, cover above the substrate 9 by resin molding 13.This is in order to prevent the lubricating oil splash that uses or prevent owing to rainwater adheres to acceleration transducer unit 4 et out of orders that cause on passenger conveying equipment 40.Thus, can further improve the reliability of acceleration transducer unit 4.
Fig. 4 has represented the control block diagram of the control setup 5 that the safety device 50 of passenger conveying equipment shown in Figure 1 40 is had.As mentioned above, in the control setup 5 of the safety device 50 of passenger conveying equipment 40, after accepting acceleration transducer unit 4 detected signals, remove and be included in by the low-frequency component in the high pass filter, processes circuit 14 detected acceleration signals.Remove the signal of low-frequency component, carry out biphase rectification by biphase rectification treatment circuit 15.Signal after the rectification carries out integration by Integral Processing circuit 16.High pass filter, processes circuit 14 and biphase rectification treatment circuit 15 and Integral Processing circuit constitute operational part 6.
The acceleration signal handled by operational part 6 in threshold value comparator circuit 17, compares with the threshold value that has preestablished.The comparison of passing threshold comparator circuit 17, when detected signal is judged as when unusual, shutdown feature 18 stops passenger conveying equipment 40.Meanwhile, unusual transmitter unit 19 is unusual to the outside report.Threshold value comparator circuit 17 and shutdown feature 18, unusual transmitter unit 19 have constituted control part 7.Acceleration transducer unit 4 also possesses the not shown break detection circuit 20 of the broken string that is used to detect power lead and signal wire (SW) and GND line.
On control setup 5 as constituted above, the input feature vector acceleration signal by the phenomenon of enumerating below.(1) acceleration signal that when jump on floor, gangway 2, produces from pedal 1.(2) lean on the acceleration signal that produces when the floor 2, gangway by umbrella etc.The acceleration signal that produces when (3) making floor, gangway 2 and pedal 1 collision by the foreign matter obstruction.Since these each phenomenon, the vibration that on floor, gangway 2 or floor, gangway support beam 3, has feature, and these vibrations are accepted as the characteristic acceleration signal.That is,
(1) from vibration or the collision of pedal 1 when the jumping over of floor, gangway 2:
Because the passenger jumps on the floor, gangway 2 with sudden force, so cause that the energy of vibration is bigger.Its result, the amplitude of the acceleration/accel that produces on floor, gangway 2 is bigger.But, can relax collision, the attenuate high frequency composition by the rubber or the resin of sole.So, be installed in floor, gangway 2 or near the acceleration transducer unit 4 it, detect the acceleration signal that radio-frequency component is faint, low-frequency component is taken as the leading factor.
(2) lean on vibration or collision when the floor 2, gangway by umbrella etc.:
Rely on the rigidity of umbrella front end, paramount frequency band produces the power of excitation.Because the generation state of power is an impulse form, so cause that the energy of vibration is less.So, the amplitude of the acceleration/accel that on floor, gangway 2, is produced, though bigger after collision just finishes, decay immediately.
Vibration or collision when (3) stopping up floor, gangway 2 and pedal 1 collision by foreign matter:
The energy that causes vibration is bigger, also comprises the power of a large amount of radio-frequency components.The acceleration/accel, the amplitude that are produced by this collision are bigger, also comprise a large amount of radio-frequency components.This phenomenon is characterised in that the acceleration/accel that continues to produce long-time collision.
Because according to the difference of the detected acceleration/accel of phenomenon, so in control setup 5, distinguish in such a way by foreign matter and stop up the collision phenomenon on the floor, gangway 2 that produces and to the phenomenon of jumping on floor, gangway 2.Detection signal by acceleration transducer unit 4 output is passed through on high pass filter, processes circuit 14, thereby discharge the influence that causes with jumping over of taking as the leading factor of low-frequency component.Then, the difference of the size by energy is distinguished by foreign matter and is stopped up the collision phenomenon on the floor, gangway 2 that produces and bump phenomenon by leaning on of generations such as umbrella.Therefore, in biphase rectification treatment circuit 15, the acceleration/accel waveform that has carried out filter process is carried out biphase rectification, thereby be transformed into the size of waveform, and in Integral Processing circuit 16, be converted into energy value.
If produce during passenger conveying equipment 40 in running and to jump over phenomenon, then the detected acceleration signal of acceleration transducer unit 4 is carried out Filtering Processing and is only become radio-frequency component by control setup 5, and the integrated value of acceleration signal diminishes.So this moment is because the integrated value of acceleration signal is littler than threshold value, so do not judge and become unusual.
Equally, bump phenomenon if produce to lean on when running passenger conveying equipment 40, then in this less phenomenon of the energy that causes vibration originally, the integrated value of acceleration signal is less.Because the integrated value of acceleration signal is littler than threshold value, does not become unusual so this also judges.In contrast, if when running passenger conveying equipment 40, produce the collision phenomenon that stops up the floor, gangway 2 that causes owing to foreign matter, then owing to cause that the energy of vibration is big, comprise a large amount of radio-frequency components in the acceleration signal that detects, so the integrated value of acceleration signal becomes greatly.So when producing collision because of the foreign matter obstruction, the integrated value of acceleration signal becomes bigger than pre-set threshold.The integrated value of threshold value and measured acceleration/accel is compared by threshold decision circuit 17.When setting threshold, can obviously compare the value of foreign matter obstruction and other phenomenon.
In addition, in order further to improve the operating efficiency of passenger conveying equipment 40, the threshold setting of the integrated value of the acceleration signal set by control setup 5 can be become many grades.At this moment, can differentiate the seriousness of the situation of foreign matter obstruction.For example, in the integrated value of setting 2 kinds of threshold values of size, acceleration signal than the 1st threshold value of low threshold value greatly and under than the little situation of the 2nd threshold value of high threshold, the foreign matter that takes place on passenger conveying equipment 40 stops up and the collision that causes is judged to be broken into slightly, and is unusual to external notification when passenger conveying equipment 40 is switched to low-speed running.So-called mile abnormality for example refers to, the situation of foreign matter and 2 collisions of floor, gangway and damage comb teeth 22.
With respect to this, under the integrated value of acceleration signal likened to the big situation of the 2nd threshold value of high threshold, judging passenger conveying equipment 40 can not remain in operation down like this, thereby stops passenger conveying equipment 40 immediately, simultaneously, unusual to external notification.By coming setting threshold in such a manner, can be under the collision of the degree of losing of comb teeth 22, do not stop and proceeding low-speed running, thereby reduce the reduction of operating efficiency.In addition,, can discharge owing to foreign matter stops up the collision phenomenon cause owing to continuing run duration with low-speed running, so, can avoid serious accident between unusual slight.
The control setup 5 of present embodiment has broken string decision circuitry 20.Action to this broken string decision circuitry 20 describes below.As mentioned above, the acceleration transducer unit 4 of safety device 50 possesses not shown power lead and output line, GND line.The output signal of acceleration transducer unit 4 comprises certain compensation (offset) amount.
In the acceleration transducer unit 4 according to above-mentioned formation, a certain in possible each line broken string takes place and produces fault.So broken string decision circuitry 20 monitors the compensation rate that is included in by in the acceleration signal of high-pass filter 14 inputs always.If this compensation rate is zero and long-term lasting, judge that then broken string has taken place for power lead and output line.In addition, if detected acceleration signal is equivalent to maximum auxiliary voltage and this state continues for a long time, then judges the GND line broken string has taken place.So,, just can be easily in early days the situation of the discomfort of acceleration transducer unit 4 be made judgement only by monitoring incoming signal.
Fig. 5 has represented other embodiment of acceleration transducer unit of the present invention in detail with lateral plan.Can detect and be fastenedly connected coming off of the substrate 9 that might take place when parts 12 are fastenedly connected on floor, gangway 2 or substrate by bolt etc. at degree of will speed up sensor unit 4 and be fastenedly connected parts 11 and fluff.The difference of the foregoing description is, substrate is fastenedly connected parts 11A～11D to be non-conductive and to be provided with the signal output terminal that connects acceleration/accel IC sheet 8 and the wiring pattern of the through hole portion that substrate is fastenedly connected parts 11A～11D etc.Be fastenedly connected at each substrate plain cushion 21A～21D is installed on parts 11A～11D, to be connected with the wiring pattern that extends to through hole portion.
In the present embodiment that constitutes in the manner described above, each plain cushion 21 plays the effect of the connection switch of the wiring that connects through hole portion.That is,, also can cut off output signal at the loosening position that takes place even loosening phenomenon takes place at 1 place that substrate is fastenedly connected parts 11A～11D.At this moment, the output signal of acceleration transducer unit 4 continues zero state for a long time, thereby broken string decision circuitry 20 (with reference to Fig. 4) can detect the loosening phenomenon that substrate is fastenedly connected parts 11.
Though in the present embodiment, substrate is fastenedly connected parts 11 and adopts non-conductive structure, even mounting blocks 10 adopts non-conductive material also can obtain same effect.When being made of mounting blocks 10 and substrate conductive material and being fastenedly connected parts 11, as long as the material of plain cushion 21 is carried out duplex, making what is connected a side with substrate 9 is electric conductivity, makes to be fastenedly connected parts 11 with substrate to be connected a side be non-conductive getting final product.
