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 the pedal 1 with loop connecting.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 in the mode of level with pedal 1 part.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 in 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, in this planar portions acceleration transducer unit 4 is installed.In addition, in this Fig. 1, although at floor, gangway support beam 3 acceleration transducer unit 4 has been installed, also can be installed on the floor, gangway 2 by degree of will speed up sensor unit 4.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 operational part 6 and the control part 7 of Integral Processing from acceleration transducer unit 4 detected signals; Wherein, control part 7, the integrated value that operational part 6 is calculated and predefined threshold value compare to judge and have or not unusually, having when unusual, stop passenger conveying equipment 40 or make its low-speed running.As shown in Figure 1, acceleration transducer unit 4 be arranged on 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 foreign matters from being blocked occurs for 1 on the pedal of passenger conveying equipment 40 or pedal 1 and 2 on floor, gangway, the collision phenomenon that is produced by foreign matter can occur on pedal 1 and 2 on floor, gangway.Because this collision can produce the acceleration/accel with larger composition at the direct of travel of pedal 1.This acceleration/accel to floor, gangway 2 and floor, gangway support beam 3 transmit.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 the circulation driving brief acceleration sensor unit 4 at pedal 1 not produce interference with 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 situation of acceleration transducer unit collision under, can prevent the damage of acceleration transducer unit 4.In Fig. 1, although be provided with the acceleration transducer unit 4 that has sensitivity at the direct of travel of pedal 1 in the side, front of floor, gangway support beam 3, if but the acceleration transducer unit 4 that will have the sensitivity of vertical is configured in following etc. such as floor, gangway 2, then can be more reliably the floor, gangway 2 that occured by foreign matters from being blocked and the collision phenomenon of pedal 1 be separated with other phenomenon.
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, the output of acceleration transducer unit 4 that has sensitivity than the direct of travel at pedal 1 is large.If the generation foreign matters from being blocked then becomes larger than the output of the acceleration transducer unit 4 that has sensitivity in vertical in the output that the direct of travel of pedal 1 has an acceleration transducer unit 4 of sensitivity.So, owing to have the acceleration transducer unit 4 of sensitivity and be inverse relationship at the output relation that the direct of travel of pedal 1 has an acceleration transducer unit of sensitivity in vertical, so, the floor, gangway 2 that can specificly be produced by foreign matters from being blocked and the collision phenomenon of pedal 1.
Fig. 2 has represented the installation portion of acceleration transducer unit 4 in detail with block diagram.On acceleration transducer unit 4, be provided with acceleration/accel IC sheet 8 at substrate 9.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 the 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 arranged and used also can only append by simple construction acceleration transducer unit 4 is set.In addition, when the acceleration pick-up that appends for detection of the acceleration/accel of 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 at substrate 9 acceleration/accel IC sheets 8 are installed according to the acceleration detection direction and get final product.In the present embodiment, although combination acceleration/accel IC sheet 8 and substrate 9 and consist of 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 by piece and be fastenedly connected between mounting blocks 10 and floor, the gangway support beam 3 although be fastenedly connected parts 11A～11D by substrate, also can replace and use these fastening connection mechanisms and use bonding grade to be fastenedly connected method.Say nothing of, also can by mounting blocks 10 substrate 9 be set directly on floor, gangway 2 or floor, the gangway support beam 3.
Fig. 3 has represented other embodiment of acceleration transducer unit 4 in detail with block diagram.In the embodiment shown in Figure 2, covered above the substrate 9 by resin molding 13.This is in order to prevent the lubricating oil splash that uses at passenger conveying equipment 40 or to prevent owing to rainwater adheres to acceleration transducer unit 4 et out of orders that cause.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 has.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 consist of operational part 6.
The acceleration signal processed by operational part 6 in threshold value comparator circuit 17, compares with the threshold value that has preseted.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 consisted of control part 7.Acceleration transducer unit 4 also possesses the not shown break detection circuit 20 for detection of the broken string that goes out 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.The acceleration signal that produces when (1) jumping over to floor, gangway 2 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) being made floor, gangway 2 and pedal 1 collision by foreign matters from being blocked.Because these each phenomenon, on floor, gangway 2 or floor, gangway support beam 3 the characteristic vibration of tools occurs, and these vibrations are accepted as the characteristic acceleration signal.That is,
(1) vibration or the collision during jumping over from pedal 1 to floor, gangway 2:
Because the passenger jumps on the floor, gangway 2 with sudden force, so cause that the energy of vibration is larger.Its result, the amplitude of 2 acceleration/accels that produce is larger on the floor, gangway.But, can relax collision, the attenuate high frequency composition by 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 forces exciting.Because the generation state of power is impulse form, so cause that the energy of vibration is less.So, the amplitude of the acceleration/accel that on floor, gangway 2, produces, although larger after collision just finishes, immediately decay.
(3) by floor, foreign matters from being blocked gangway 2, and vibration or collision during pedal 1 collision:
The energy that causes vibration is larger, also comprises the power of a large amount of radio-frequency components.The acceleration/accel, the amplitude that are produced by this collision are larger, 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 the collision phenomenon on the floor, gangway 2 that is produced by foreign matters from being blocked and to the Leaping phenomenon on floor, gangway 2.Detection signal by acceleration transducer unit 4 output is passed through at high pass filter, processes circuit 14, thereby discharge the impact 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 the collision phenomenon on the floor, gangway 2 that is produced by foreign matters from being blocked and is bumped phenomenon by leaning on of the generations such as umbrella.Therefore, in biphase rectification treatment circuit 15, the Acceleration pulse 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 Leaping phenomenon during passenger conveying equipment 40 in running, the detected acceleration signal of acceleration transducer unit 4 then carries out filtering by control setup 5 and processes and only become radio-frequency component, and the integrated value of acceleration signal diminishes.So this moment is because the integrated value of acceleration signal is less than threshold value, so do not judge into unusual.
Equally, bump phenomenon if produce to lean on when running passenger conveying equipment 40, then in this less phenomenon of the energy that originally causes vibration, the integrated value of acceleration signal is less.Because the integrated value of acceleration signal is less than threshold value, so this does not judge into unusually yet.In contrast, if when running passenger conveying equipment 40, produce the collision phenomenon on the floor, gangway 2 that causes owing to foreign matters from being blocked, then owing to cause that the energy of vibration is large, 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 foreign matters from being blocked, it is larger than predefined threshold value that the integrated value of acceleration signal becomes.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 matters from being blocked and other phenomenon.
In addition, in order further to improve the operating efficiency of passenger conveying equipment 40, the Threshold 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 matters from being blocked.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 in than the little situation of the 2nd threshold value of high threshold, the foreign matters from being blocked that occurs at the passenger conveying equipment 40 and collision that causes is judged to be broken into slightly, 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, be compared in the large situation of the 2nd threshold value of high threshold in the integrated value of acceleration signal, judging passenger conveying equipment 40 can not remain in operation down like this, thereby stops immediately passenger conveying equipment 40, simultaneously, unusual to external notification.By coming in such a manner setting threshold, 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, owing to continuing run duration with low-speed running, can discharge the collision phenomenon that causes owing to foreign matters from being blocked, so, can avoid serious accident between unusual slight.
The control setup 5 of present embodiment has broken string decision circuitry 20.The below describes the action of this broken string decision circuitry 20.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 occurs 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 occured 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 occured.So, only by monitoring incoming signal, just can be easily in early days the situation of the discomfort of acceleration transducer unit 4 be judged.
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 occur 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 above-described embodiment 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 section that substrate is fastenedly connected parts 11A～11D etc.Be fastenedly connected parts 11A～11D at each substrate plain cushion 21A～21D is installed, to be connected with the wiring pattern that extends to through hole section.
In the present embodiment that consists of in the manner described above, each plain cushion 21 plays the effect of the connecting valve of the wiring that connects through hole section.That is, even at 1 place that substrate is fastenedly connected parts 11A～11D loosening phenomenon occurs, also can cut off output signal at the loosening position that occurs.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.
Although 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 consisted of mounting blocks 10 and substrate by conductive material and be fastenedly connected parts 11, as long as the material of plain cushion 21 is carried out duplex, make and are connected the electric conductivity that is that connects a side with substrate, make to be connected parts 11 with substrate to connect a side be non-conductive getting final product.
