Start process to the operation of escalator 1a to be below described.Run to start to process and mainly confirm step 11 exists with or without passenger and after confirming that step 11 does not have passenger, make escalator 1a start the process usually run.In addition, before operation starts usually for this, starting process as operation, carrying out the process for detecting passenger, at this, this operation is called preparation runs and distinguished with usual operation.The speed that preparation runs can be set to identical with the speed usually run, but preferably becomes the speed than usually running slow the Speed Setting that preparation runs.
Fig. 6 represents that the operation involved by the first embodiment starts the diagram of circuit of process.After receiving at control part 35 instruction running and start to process, start to perform this flow process.First, control part 35 run start to process before using the step 11 that exposes as the object of occupant detection process, judge whether to complete occupant detection process (S411) to all object steps 11.
When being judged as completing occupant detection process to all object steps (S411 is yes), control part 35 is identified as and is in normal condition, by making drive part 31 action bring into operation (S491), and process ends.
On the other hand, when being judged as also not completing occupant detection process to all object steps 11 in S411 (S411 is no), control part 35 utilizes output circuit 36 to make range sensor 51 action, obtain the detection data (S423) of range sensor 51 thus from input circuit 34, and judge in detection range, whether have passenger to exist (S426) according to obtained detection data.
When being judged as there is no passenger in detection range (S426 is no), control part 35 carries out preparation and runs, utilize output circuit 36 to make drive part 31 action, make the step 11 movable length L (S461) on direct of travel exposed, and make flow process enter S411.Thereby, it is possible to carry out occupant detection process to next detection range, and, by repeatedly carrying out above-mentioned steps, occupant detection process can be carried out continuously, until all object steps 11 enter below floor.Make the time of drive part 31 action in running as preparation, the speed run according to length L and preparation in advance calculates and is stored in memory device 41.
When being judged as having passenger to exist in detection range in S426 (S426 is yes), being identified as and there occurs exception, carry out the Recovery processing (S481) specified, and make this flow process enter S491.In Recovery processing, by the handler of abnormal notice escalator 1a, or instruction handler reminds the passenger on step 11 to take more care, or reminds the passenger on step 11 to take more care by broadcast.
Be described running the flow process starting to process above.
Whether start process according to this operation, a range sensor 51 can be used to detect on step 11 all object steps 11 has passenger to exist.
(the second embodiment)
In the present embodiment, the embodiment carrying out occupant detection process in the preparation operation carried out continuously is described.
The structure of the escalator 1a of present embodiment is identical with the first embodiment.
As shown in S461, start in process, to carry out preparation in the operation of the first embodiment and run, in units of each detection range, make drive part 31 carry out stepwise operation.On the other hand, start in process in the operation of present embodiment, during operation starts process, carry out preparation continuously run.Other steps that the operation of present embodiment starts to process are the same with the first embodiment.
Below to carrying out on one side preparation operation continuously, the condition of the moving velocity of the step 11 when detecting the passenger on all object steps 11 is described.
In the present embodiment, the movement speed v of step 11 is set smaller than the angular velocity omega of range sensor.Step 11 is being set as t by the time of detection range, the time light beam 57 of range sensor 51 being moved on the skirt section backplate 22b relative with range sensor 51 detection range length L, when being set as T, can represent with following formula for the condition detecting passenger.
t＞T……(E1)
Formula (E1) can represent with following formula further.
L/v＞L/(ω×r)+τ……(E2)
In formula, τ represents the response time of range sensor 51.Formula (E2) represents the condition only when a horizontal surface detects passenger.As shown in Figure 4, at handrail 16a, between 16b and the wall outside it, there is no space, the occasion that passenger falls towards the outside of handrail 16a, 16b can not occur, the condition of formula (E2) can be used.At handrail 16a, when the both sides of 16b is provided with the protective material preventing from falling, equally also can use the condition of formula (E2).
Fig. 7 represents handrail 16a, and the outside of 16b has the block diagram of the occasion in space.Before escalator 1a brings into operation, at handrail 16a, 16b has the occasion that passenger exists, then, when running beginning, passenger likely falls towards the outside of handrail 16a, 16b.In the present context, except detecting the passenger on step 11, range sensor 51 is also to handrail 16a, and the passenger on 16b detects.Therefore, the driver train that range sensor 51 has, except making light beam 57 except vertical axis scans, can also make light beam 57 move in a different direction and detection range is moved.Therefore, range sensor 51 has three detection ranges.The detection range length of three detection ranges represents with L1, L2 and L3 respectively.Representing with following formula (E3) for the condition detecting passenger now.
L/v＞(3×L/(ω×r)+t1+t2)+τ0……(E3)
In formula, t1 represents that range sensor 51 moves to the time on handrail 16b from step 11 in detection range, t2 represents that range sensor 51 moves to the time of handrail 16a in detection range from handrail 16b, and τ 0 represents the aggregate value of the response time of each movement of range sensor 51.Wherein, detection range length L is length the shortest in three the length L1 of detection range on direct of travel, L2 and L3.
When needs increase detection range further, represent as shown in the formula (E4) for the condition detecting the passenger in all detection ranges.
L/v＞(n×L/(ω×r)+t1+…+tn)+τ0……(E4)
Wherein, t1, t2 ... tn represents that detection position is set in the time needed for each detection range by range sensor 51.
In above condition, when having one or two detection ranges, also can satisfy condition even if movement speed v is common speed and 30m/min.When there being three detection ranges (occasion of formula (E3)), preferably v is set as below 30m/min.When there being detection range (occasion of formula (E4)) of more than four, preferably v is set as below 20m/min.In addition, the movement speed v satisfied condition also can because of can detecting distance r and range sensor 51 setting position and width W etc. and change.
When starting, because step 11 accelerates, so step 11 couples of passengers produce power.In addition, along with the speed of step 11 accelerates, the friction coefficient on step 11 surface may reduce.It is the tendency of inverse ratio that friction coefficient has with 1/2 power of speed.The reason causing friction coefficient to reduce may be accelerate along with speed and cause the temperature of friction face to rise, or makes the concavo-convex influence power reduction etc. to friction coefficient of friction face because of the change of contact condition.In addition, be also likely because step 11 part residing for passenger is in the state especially easily slipped because of the impact of breakage etc.Therefore, be preferably than usually running low speed by the Speed Setting that preparation runs.
When escalator 1a is descending escalator, the passenger on step especially easily slips.The time that the acceleration/accel of step 11 reaches α being set as Ta, the distance of advancing during Ta is set as La, is that v, La and α represent with following formula (E5) by the Speed Setting reached after Ta.
La＝1/2×v×Ta……(E5)
α＝v/t……(E6)
In formula, La is the permissible value that preparation runs passenger's miles of relative movement when starting.This La is being set as about the 1/3 i.e. 120mm of depth direction size of the direct of travel equaling step 11 α is set as 0.1m/sec
2time, v is approximately 0.16/sec (being about 10m/min), and Ta is 1.6sec.Therefore, in order to prevent the passenger on step from slipping, the Speed Setting preferably preparation run is below 10m/min.
By the speed that Speed Setting preparation run is lower than usually running, the speed usually run with employing carries out, compared with the occasion of occupant detection process, can reducing current sinking.That is, by reducing the speed of preparation operation and reducing acceleration/accel, can starting current be reduced, thus can power consumption be reduced.
Operation according to the present embodiment starts process, can be detected on it exist with or without passenger by continuous print preparation operation to all object steps 11.
