The specific embodiment
Below, describe with reference to the embodiment of accompanying drawing the safety device of the apparatus of passenger conveyor that the present invention relates to.
Fig. 1 is the block diagram of an embodiment of the safety device of the apparatus of passenger conveyor that the present invention relates to of expression, and Fig. 2 is the summary construction diagram of apparatus of passenger conveyor.
Apparatus of passenger conveyor, for example be that tilted configuration is between floor that separates up and down and floor, and be configured to can be at the escalator 1 that rises or descend and switch between the operation, keystone configuration as this escalator 1 roughly has: ring-type links and the mobile a plurality of steps 2 that circulate, erect the both sides that are arranged on above-mentioned step 2 railing 3, cover the lower inside of above-mentioned railing 3 interior deck 4, cover the outer deck 5 in the outside, bottom of railing 3, supported by railing 3 and with step 2 synchronization-moving moving hand-rails 6.
Wherein, have or not the passenger near the hazardous location in order to detect, a component part as the safety device of escalator 1 for example is provided with the object sensor 7 that utilizes laser beam.Particularly, near the companion way outer deck 5 is provided with object sensor 7, this object sensor has on one side the 71 below elongations to the gangway 61 of moving hand-rail 6, and another side 72 is along the moving direction of step 2 and to the roughly fan-shaped surveyed area 73 of the outer lower portion elongation of moving hand-rail 6.In addition, in Fig. 1, for convenience of explanation, only the side at escalator 1 illustrates sensor 7, but actually, i.e. the sensor of the opposite side relative with diagram sensor 7 of opposite side is arranged at outer deck 5.In addition, in Fig. 1, only illustrate sensor 7, but preferably on the outer deck 5 about the companion way of last step side, pair of sensors is set also in the lower step side.
Fig. 2 is the control system summary construction diagram of the apparatus of passenger conveyor of one embodiment of the invention.As shown in Figure 2, in the escalator 1, sensor 7 is connected with signal processing mechanism 10, send acceptance division 12 by the in-to-in serial communication that is positioned at signal processing mechanism 10, reception is from the data of sensor 7, after in CPU11 data being handled, from interface portion 14 output results.The output of signal processing mechanism 10 is sent to control mechanism 20, by control mechanism 20 startings and the corresponding safe action of state.Has safety gear, described safety gear detects near the object of the gangway 61 of moving hand-rail 6 based on sensor 7 and the first object detection signal of exporting and detect the object that stretches out laterally from moving hand-rail 6 and the second object detection signal of exporting and follow action, starts safe actions different more than two kinds or three kinds thus respectively.As safe action, at first, utilize near be arranged on the companion way loud speaker 251,252 via phonetic synthesis mechanism 24, point out broadcasting to the passenger, and reduce the output frequency of inverter part 21.Thus, reduce the rotative speed of induction motor (IM) 22, make the running velocity of escalator be reduced to safe speed.And then, by telemonitoring portion 23,, confirm the safety management state of escalator to urge it with the management devices circular of this situation of emergency situation to maintenance management company taken place.
In addition, sensor 7 for example makes laser light-projecting portion and the rotation of laser light accepting part, the relative distance between output and the obstacle and the anglec of rotation of laser light accepting part.These data send acceptance division 12 via the serial communication that is arranged at signal processing mechanism 10 and receive at CPU11.These data are data of circle coordinates system, therefore, will detect distance and be made as r, when the anglec of rotation is made as θ, be applied to formula (1), these data are converted to XY plane coordinates data after, generate with sensor 7 be the center and object between coordinate data figure (coordinate data map).
x＝r·cosθ，y＝r·sinθ………(1)
Carry out the coordinate data figure of this coordinate diagram and the fixture of measuring in advance that comprises the escalator main body under the state that is in objects such as not having passenger and luggage overlapping.And, only represented fixture object data in addition, i.e. the plane coordinates data plot of objects such as the passenger of escalator and luggage by removing the coordinate data of fixture, can calculating.According to this plane coordinates data plot, calculate the center-point of object, and be stored in the memory device 13 of signal processing mechanism 10.Every short time gap, for example every 100ms, with these record data in the past certain hour, for example pass by 1 second with interior data storage in memory device 13, thereby monitor the amount of movement of the object center-point of each object, calculate the amount of movement of each object.
Fig. 3 is the schematic diagram of the object detection of one embodiment of the invention, Yi Bian with reference to Fig. 3, Yi Bian the surveyed area of object and the principle of safety gear are described.
At first, the object detection area to sensor 7 describes.According to distance from the gangway 61 of moving hand-rail 6, set first surveyed area 74, when in first surveyed area, detecting object, point out broadcasting.Then, according to distance setting second surveyed area 75 from the gangway 61 of moving hand-rail 6, when in second surveyed area, detecting object, point out broadcasting and escalator stop to handle.At this, have or not object to be called the first object detection signal above-mentioned detection, but in the present embodiment, the first object detection signal is further divided into the first and second above-mentioned surveyed areas and export near the output of the detection of the gangway 61 of moving hand-rail 6.
In addition, have or not object to stretch out from handrail 6 in order to detect, detection has or not identical object to have specified time in the 3rd surveyed area 76, and after detecting this situation, export the second object detection signal, point out broadcasting, and reduce the speed of escalator.At this, the reduction of speed of the escalator that the stopping of the escalator of carrying out when for example detecting object in the second above-mentioned surveyed area 75 handled and carry out when continuing to detect object in the 3rd surveyed area 76 is handled and is called the emergency situation pattern.
Below, the action of the safety device of the apparatus of passenger conveyor in one embodiment of the invention is described.For example, when children's hand during near the gangway 61 of moving hand-rail 6, sensor 7 detects has object to exist in first surveyed area 74.Corresponding with this testing result, control mechanism 20 utilizes near the loud speaker 251,252 that is arranged at the companion way via phonetic synthesis mechanism 24, plays the broadcasting of pointing out of contents such as " gangway of handrail are abnormally dangerous, please beyond this point " to the passenger.Even after this points out broadcasting, if these children's hand during further near the gangway 61 of moving hand-rail 6, sensor 7 detects in predefined second surveyed area 75 and has object.At this moment, control mechanism 20 utilizes loud speaker 251,252 via phonetic synthesis mechanism 24, plays the broadcasting of pointing out of contents such as " escalator will stop, and please note " to the passenger.Simultaneously, make output frequency be reduced to the instruction of 0Hz to inverter part 21 outputs, the rotative speed of induction motor (IM) 22 is reduced, then, after to be reduced to the essence of predesignating be zero speed, escalator 1 is mechanically remained on quiescence in speed by brake equipment.
In addition, when escalator 1 rises operation, when the health that rides in the children on the escalator 1 reaches the outside from moving hand-rail 6, and when keeping this state always, sensor 7 detects and have the object that reaches the outside from moving hand-rail 6 in the 3rd surveyed area 76 (when stretching out outside the moving hand-rail may nipped zone), judges simultaneously whether this object continues to have existed specified time in the 3rd surveyed area 76.And, in each scanning period of sensor 7, judge whether whether this detected object has moved a certain amount of above distance, be placed on the handrail to judge this object.Judging that there has been specified time in this object in the 3rd surveyed area 76, and when detecting this object and handrail with moved further, can be judged as is that passenger's health has stretched out handrail.At this moment, control mechanism 20 utilizes loud speaker 251,252 via phonetic synthesis mechanism 24, to the passenger play " please health is not stretched out handrail, so very dangerous." etc. content point out broadcasting.Simultaneously,, reduce the rotative speed of induction motor (IM) 22, reduce the running velocity of escalator 1 with this by reduce the instruction of frequency to inverter part 21 outputs.Thus, allow before the narrow angle portion of the triangle that the passenger forms between near the moving hand-rail 6 that moves by the outer ornamental portion of the horizontal top of building or adjacent escalator with on crisscross if having time, the posture of danger is returned to normal posture.On the other hand, when the passenger had reached the outside of moving hand-rail 6 with hand suddenly for some reason, sensor 7 detected in the 3rd surveyed area of predesignating 76 and has object.But,,, therefore can continue to make escalator 1 normally to move so control setup 20 can not be judged as emergency situation with it mistakenly because this object does not continue to exist specified time in the 3rd surveyed area 76.
Whether according to present embodiment, can detect near the object of the gangway 61 of moving hand-rail 6 simultaneously and detect by a sensor 7 has object to be in the state that reaches the outside from moving hand-rail 6.Therefore, can be when reducing components number, guarantee the safety of the narrow angle portion of the safety of gangway 61 of moving hand-rail 6 and triangle, thus, can in cost-cutting, guarantee the safety of escalator 1.In addition, owing to can judgment object be temporarily to reach the outside from moving hand-rail 6, still reach the outside and have the danger of being clamped from moving hand-rail 6 constantly, therefore, can only when emergency situation has taken place, just take adequate measures by the narrow angle portion of triangle.In addition, can also judge whether inspected object is the fixed obstacles such as advertisement that are arranged on outer deck department etc.Thus, can prevent that escalator 1 from moving with the emergency situation pattern under unnecessary situation, and can when keeping operating efficiency, guarantee the safety of height.In addition, detecting object, and, pointing out broadcasting, can impel the passenger to avoid emergency situation by phonetic synthesis mechanism 24 having detected object when moving hand-rail 6 has reached the outside near during the gangway 61 of moving hand-rail 6.And, near the hazardous location or when having reached the hazardous location, enter the emergency situation pattern the passenger by making escalator 1, can help the passenger to take to avoid the action of emergency situation reliably.
In addition, in the present embodiment, the escalator of carrying out in the time of will in the second area 75 during first and second surveyed areas 74,75 of the first object detection signal take place can to export when unusual, detecting object 1 stop to handle the emergency situation pattern that is set at.The reduction of speed of the escalator of carrying out in the time of in addition, will detecting object in the 3rd surveyed area 76 and continue to exist 1 is handled the emergency situation pattern that also is set at.But self-evident, the present invention is not limited to this, also can suitably set according to environment for use of apparatus of passenger conveyor etc.
Below, the configuration of object sensor 7 and the variety of use form are described.
At first, as mentioned above, preferably on Fig. 1 not shown the companion way of step side about outside object sensor 7 also is set on the deck.At this moment, there is no need to use all the time whole measuring abilities of each object sensor.For example, when escalator 1 rises operation, because the effect of handrail outlet has been played in 61 of the handrail gangways of the companion way of lower step side, so we can say that the danger of the accident that sandwiches at this place is very little.At this moment, use the essentiality of the first object detection signal (first and second surveyed areas 74,75 all can) of object sensor 7 little.Thus, can not use the first object detection signal, perhaps can not produce the first object detection signal itself.At this moment, the situation of last step side companion way is just in time opposite with above-mentioned situation, and to stretch out the use essentiality of the second object detection signal of the 3rd surveyed area 76 of situation from handrail little from detecting.Thereby, can not use the second object detection signal, perhaps can not produce the second object detection signal itself.Thus, in the escalator of operation that rises, can use second object detection signal of lower step side senser and the first object detection signal of last step side sensor in Min. ground.
In addition, if the bidirectional escalator that can between rising/decline operation, switch, when the type of service with above-mentioned rising operation escalator switches to the type of service of the operation that descends, can use first object detection signal of lower step side senser and the second object detection signal of last step side sensor in Min. ground.
As mentioned above, by near the deck outside about the oscilaltion mouth of apparatus of passenger conveyor sensor being set, four sensors promptly are set, can detect more reliably and have or not object near the gangway of moving hand-rail and have or not object to reach the outside, and can carry out safe action from moving hand-rail.
