Abstract

An automatic operating unit of man conveyor comprising a first detector for detecting a passenger approaching the entrance/exit of a man conveyor, and a second detector for detecting a passenger passing just in front of a footboard. When the first detector does not detect a passenger but the second detector detects a passenger, a man conveyor stopping on stand-by blocks the starting of the footboard. A man conveyor operating at a low speed at the time of stand-by makes a transition to continuous operation of the footboard at a rated speed and resets to automatic operation when the first detector detects a passenger.

Description

The automatic rotating device of People's Bank of China's belt conveyor

Technical field

The present invention relates to the device that detects the 1st whether approaching detector of passenger and turn round automatically having to People's Bank of China's belt conveyor of passenger's the 2nd detector that passes through to detect, according to the detected state of described detector.

Background technology

In the past, known have People's Bank of China's belt conveyor with escalator, movable sidewalk etc. to make to make the passenger who approaches to take advantage of inlet is detected and starts and turn round, make when the no passenger the self-braking device of above-mentioned running automatically.For example in Japanese patent laid-open 6-87592 communique, Japanese patent laid-open 10-182050 communique, disclosed the device that uses reflection-type occupant detection device.

But, use the reflection-type occupant detection device of energy waves reflection, because detected object thing and environmental conditions and its detect distance change and et out of order easily easily, so the problem below existing.

(1) at a side stopping port detector et out of order and lose the occasion of measuring ability

In the form that step stops when standby, when the detector et out of order of the stopping port opposite with direct of travel, might take place the passenger from reciprocal stopping port take advantage of into situation.This occasion, when detection have from the stopping port of regular direction take advantage of into the passenger time, by make from the walking of negative side passenger always on step to reversing sense make the step starting and make that the passenger drops to may.In addition, though at the detector et out of order and can not to take advantage of from regular direction into the occasion that detects of passenger, also exist the passenger is detected the problem that makes the step fly start from negative side passenger always in the walking on step.

In the form that step turns round with low velocity when standby, considered not take place from negative side passenger always take advantage of into situation, but, continue to keep the running of low velocity, so there is the problem of convenience reduction owing to can not the passenger at stopping port be detected.In addition, under this state, the people to reciprocal stopping port near or from regular direction take advantage of into the passenger when port for drawdown detects, exist and make the passenger be multiplied by the problem that begins to quicken under the state on the step.

Especially, reflection-type occupant detection device is not the device that only the belt conveyor user of People's Bank of China is detected, because to detecting by people on every side, so be easy to generate above-mentioned problem yet.

(2) detection at a side stopping port place detector detects the unsettled occasion that becomes apart from producing to change to make

As the detection unsettled major cause that becomes, can enumerate passenger's clothes and action, detector life-span etc.

In this occasion, in the form that step stops when standby since detect slack-off, so till the passenger takes advantage of to the step, do not produce enough acceleration, the convenience reduction.In addition, detecting extremely slow occasion, when taking advantage of, might produce the anxiety that step starting, passenger drop to into step.

In the form that step turns round with low velocity when standby, since also slack-off when detecting the acceleration that causes because of low velocity when slack-off, so still there is the problem of convenience reduction.

On the other hand, putting down in writing at Japanese patent laid-open 11-292447 communique: as to the passenger whether near the 1st detector that detects, use utilizes the reflection-type occupant detection device of energy waves reflection, as the 2nd detector that the passenger to the position, step dead ahead by People's Bank of China's belt conveyor detects, use the infiltration type occupant detection device of projecting beam.But,, do not consider reflection-type occupant detection device et out of order yet or detect the unstable timer-operated problem that becomes even in this communique.

Summary of the invention

The present invention makes in order to address the above problem, and its purpose is, though provide situation such as detector et out of order, the passenger take advantage of fashionable can et out of order and can improve convenience and the automatic rotating device of People's Bank of China's belt conveyor of maintenance property yet.

The automatic rotating device of People's Bank of China of the present invention belt conveyor is to make in People's Bank of China's belt conveyor standby (stopping), does not detect the passenger and the 2nd detector detects the device that stops the pedal starting when passenger is arranged at the 1st detector.

In addition, the automatic rotating device of People's Bank of China of the present invention belt conveyor is to make in People's Bank of China's belt conveyor standby (low-speed running), does not detect the passenger and the 2nd detector detects when the passenger is arranged and makes the pedal device of running continuously with command speed at the 1st detector.

In addition, be to make as the 1st detector to use the detector of the form that the passenger is detected by the backward wave of energy waves, use the device of the detector of the form that the passenger is detected by the blocking of energy line as the 2nd detector.

In addition, be make by the 1st detector the passenger is detected the pedal moving velocity that starts arrive specified speed before, when the 2nd detector detect the passenger is arranged state continuously for stipulated number when above, make the pedal device of running continuously with command speed.

In addition, be to make the device that after continuous running is shifted, when the detection of the 1st detector has the passenger, returns back to automatic running at pedal once more.

In addition, be to make at the 1st detector not detected the passenger and the 2nd detector detects when the passenger is arranged or detect at the 1st detector and to have before passenger's back step arrives specified speed, the device that the state that the 2nd detector detects the passenger is exported abnormal signal and the experience of abnormality juding information is write down to the outside when above for stipulated number continuously.

The specific embodiment

In order to illustrate in greater detail the present invention, with reference to the accompanying drawings its top stopping port is described.(because the bottom stopping port also is same, its explanation of Therefore, omited.)

Example 1 (claim 1,3,4,6, Fig. 1～4)

In Fig. 1 and Fig. 2, the 1st, the body of People's Bank of China's belt conveyor of escalator etc.; The 2nd, with the synchronization-moving moving hand-rail of pedal (not shown); The 3rd, the floor 4 that is laid on the escalator stopping port is arranged on the interior control panel of truss; The 5th, the ground of stopping port; The 6th, top the 1st detector that constitutes by the reflection-type occupant detection device energy line with the radiation near infrared ray that is arranged on the stopping port bottom, super sonic etc., that utilize its backward wave to detect the whether approaching surveyed area 6a of passenger; The 7th, top the 2nd detector that constitutes with its blocking and to passenger's the infiltration type occupant detection device that passes through to detect by the path that crosses the passenger in the stopping port bottom and projecting beam 7a, by the passenger.

Among Fig. 3,8 be arranged on the bottom stopping port, have bottom the 1st detector with top the 1st detector 6 said functions; 9 be arranged on the bottom stopping port, have bottom the 2nd detector with top the 2nd detector 7 said functions; The 10th, by having or not of passenger being arranged and the starting of People's Bank of China's belt conveyor stopped to send the starting decision maker of instruction by 6～9 detections of above-mentioned each detector; The 11st, the actuating device that the running of People's Bank of China's belt conveyor is stopped to control by instruction by starting decision maker 10; The 12nd, the occupant detection device for detecting fault that the fault of each detector 6～9 is judged; The 13rd, the siren horn that the fault of detector 6～9 is reported to the police; The 14th, the experience memory device that the experience of the fault of detector 6～9 is stored; The 15th, detect the driving machine (not shown) of People's Bank of China's belt conveyor speed, be the speed detector of the moving velocity of pedal; The 16th, to the moving velocity of passenger by 7,9 o'clock pedal of the 2nd detector whether than specified value low judge take advantage of fashionable speed decision maker; The 17th, the low speed of taking advantage of indegree to count to the passenger when the moving velocity of pedal is low speed is taken advantage of into counting machine.

Then, with reference to Fig. 4 the action of this example is described.

The automatic function of motion of stop type when this People's Bank of China's belt conveyor has standby.That is to say, be when no passenger pedal to be stopped and standby, can realize quiet and energy-conservation device with regard to entry into service when detection has the passenger.

At step S1, take advantage of counts N to be set at 0 low speed into counting machine 17.At step S2, People's Bank of China's belt conveyor becomes standby (stopping) state.At step S3, whether 12 pairs of tops of occupant detection device for detecting fault the 1st detector 6 has detected the passenger is judged, enters step S4 not detecting the occasion have, whether top the 2nd detector 7 has been detected the passenger judged.Do not detecting the occasion have, be judged to be no passenger and return step S2.The 2nd detector 7 detects the occasion that the passenger is arranged on top, enters step S5, and 10 outputs of starting decision maker stop starting orders, and the starting by 11 pairs of pedals of actuating device is stoped.And at step S6, occupant detection device device for detecting fault 12 is to the annunciator 13 output abnormality signals of monitor, supervisory control center, fault display device etc., and abnormality juding information is recorded in the experience memory device 14.Here, step S2～S5 constitutes starting decision maker 10.

Like this, in the stopping of People's Bank of China's belt conveyor, when the 1st detector 6 does not detect the passenger and the 2nd detector 7 detects when the passenger is arranged, because the starting to People's Bank of China's belt conveyor is stoped, so, can prevent from after the passenger takes advantage of People's Bank of China's belt conveyor in stopping, to produce the situation of starting in the occasion that can not detect the passenger because of the 1st detector 6 failure and other reasons.

Then, detect when the passenger is arranged, make timer (not shown) starting, remove instruction in the standby of step S8 output People's Bank of China belt conveyor at step S7 when be judged to be the 1st detector 6 at step S3.At step S9 whether the 2nd detector 7 having been detected the passenger judges.Not detecting the occasion that has, wait for through setting-up time at step S10, when through setting-up time, export the halt instruction of People's Bank of China's belt conveyor and return step S2 at step S11.

Then,,, enter step S12, take advantage of fashionable speed decision maker 16 to judge that from the output of speed detector 15 speed of pedal is whether more than specified speed when the 2nd detector 7 detects when the passenger is arranged at step S9.If less than specified speed, then enter step S13, low speed is taken advantage of whether the counts N of counting machine 17 is to judge more than 5.As be less than 5 times, times N is added 1, in step S16, travel to automatic running and return step S2.In addition, be more than 5 as counts N, then in step S17, People's Bank of China's belt conveyor is turned round continuously with command speed, at step S18 output abnormality signal, report to the police, and abnormality juding information is recorded in the experience memory device 14 by annunciator 13.Here, step S3, S7～S9, S12, S13 constitute occupant detection device device for detecting fault 12, and step S17 constitutes starting decision maker 10.

Like this, at step S8, before the moving velocity of the pedal of starting arrives more than the specified speed, in 7 detections of the 2nd detector passenger's number of times being arranged is occasion continuous more than the stipulated number, owing to turn round continuously with command speed, utilize the dwindling etc. of detection distance of the 1st detector 6, under the state that pedal is not enough quickened, can prevent that the passenger from taking advantage of the situation on the pedal.

In addition, not detecting at the 1st detector 6 has the passenger, and the 2nd detector 7 detects the occasion that the passenger is arranged, or after 6 detections of the 1st detector have the passenger, the 2nd detector 7 detects that passenger's state is arranged is occasion continuous more than the stipulated number before pedal arrives specified speed, with abnormal signal to for example monitor, the supervisory control center, fault display devices etc. are exported, and owing to leave the experience of abnormality juding, so the fault of the 1st detector and the reduction of detectability can be informed as soon as possible, can improve maintenance, and after returning back to automatic running, also just can be when maintenance etc. above-mentioned experience be confirmed.

In addition, when the speed that is judged to be pedal at step S12 when specified speed is above, make the counting N of counting machine 17 be back to 0 at step S15, S16 turns round automatically in step.

In addition, here, the speed that the 2nd detector 7 is detected the pedal the when passenger is arranged becomes more than the specified speed as condition, also just can detect when the passenger is arranged from the 1st detector 6 to this, detect to the 2nd detector 7 and arranged as condition passenger's elapsed time.

Example 2 (claim 2～6, Fig. 1～3, Fig. 5)

The automatic function of motion of low-speed running type when People's Bank of China's belt conveyor of example 2 has standby.That is to say, make pedal standby movably with low velocity during no passenger, when detection had the passenger, beginning is running automatically, realizes quiet and energy-conservation.

Then, with reference to Fig. 5 the action of this example is described.In addition, because fundamental operation is same with Fig. 4, so mainly the point different with Fig. 4 described.

At step S1, take advantage of counts N to be set at 0 low speed into counting machine 17.At step S21, People's Bank of China's belt conveyor becomes standby (low speed) state.At step S3 whether the 1st detector 6 has been detected the passenger and judged, entered step S4 not detecting the occasion have, whether the 2nd detector 7 has been detected the passenger judged.As detection the passenger is arranged, enters step S22, People's Bank of China's belt conveyor is turned round continuously with command speed, at step S23 output abnormality signal, by annunciator 13 report to the police and with abnormality juding information be recorded in the experience memory device in.And, wait for that at step S24 6 detections of the 1st detector have the passenger, have the passenger to return back to automatic running afterwards in step S25 as detection, and are back to step S21.Here, step S22, S24, S25 constitute running return mechanism automatically.In addition, at step S26, the standby command of output People's Bank of China belt conveyor.

Like this, at pedal after continuous running is shifted, when 6 detections of the 1st detector have the passenger, owing to return back to automatic running once more, even it is so former thereby cause the reduction of the detectability of the 1st temporary transient detector 6 because of environment and passenger's clothes etc., also can carry out answer, and can improve convenience to automatic running.

In addition, not detecting at the 1st detector 6 has the passenger and the 2nd detector 7 detects the occasion that the passenger is arranged, output abnormality signal and to this warning, and owing to leave the experience of abnormality juding, so can inform the reduction of the fault and the detectability of the 1st detector 6 as soon as possible, and can improve maintenance, and after returning back to automatic running, can also be when maintenance etc. the experience of transferring to continuous running be confirmed.

In addition, in above-mentioned each example, the 1st detector 6 is to use reflection-type occupant detection device, this be since can from away from the position of stopping port to the passenger whether near the cause that detects.But the 1st detector 6 is not limited to reflection-type occupant detection device, as long as it is just passable to the approaching situation of stopping port to detect the passenger, even the detector of other form also is enough to use.
