The detection signal 68 from the area detection sensor 64 is "O
N ", the flag flg is set to flg = 1,
The presence or absence of a peak is determined, and if there is a peak, the height of the peak is
It is determined whether or not the height of the person is greater than or equal to a predetermined height,
If the peak height is higher than the set value,
The peak number C of the height to be obtained is integrated as C = C + 1,
These processes correspond to detection signals from the area detection sensor 64.
This is repeated until 68 becomes “OFF”. After this, before
The detection signal 68 from the area detection sensor 64 is “OFF”
Becomes greater than the set value because flg = 1.
The number C of height peaks is compared with a threshold value J for determining traffic congestion, and C>
If it is J, it is determined that traffic is congested and deceleration is performed.
On the other hand, if C ≦ J, it is determined that no congestion has occurred
Control is returned to the initial stage and reset. That is, during operation, the downstream end of the high-speed moving section
Pallets 3 are installed in the width direction at the top of the sidewalk
Of the pallet 3 by the distance detection sensor 67
If there is a person on the pallet 3 by monitoring the distance
Is detected, and the area detection sensor 64
Set the position of the distance detection sensor 67 on the pallet 3
It is detected whether or not the prohibited area N has passed, and the control device
At 71, a detection signal from the area detection sensor 64
68 and a detection signal 69 from the distance detection sensor 67.
Is determined based on the number of persons in the no-bound area N based on the
If the number of people exceeds the threshold, it is determined that traffic is
The command 70 is output. As a result, as in the prior art, in the width direction of the sidewalk
When the detection light Y that is emitted is blocked,
The traffic detection sensor 63 such as an optical sensor
Unlike detecting the occurrence, pallet 3 is prohibited
This is a case where people stand side by side in the stop area N.
Even worried about detecting the flow of people less than it actually is
And the flow of people is accurately and reliably grasped, improving accuracy
Can be achieved. In this way, the flow of a person is accurately and reliably grasped.
And smooth operation can be achieved. The detection of traffic congestion on a variable speed moving sidewalk according to the present invention
The system is not limited to only the examples shown above.
Therefore, various changes may be made without departing from the gist of the present invention.
Can of course be added. As described above, the variable speed type of the present invention is
According to the traffic detection system on the moving sidewalk, accurate flow of people
And it can be grasped reliably, which can facilitate driving.
It can provide an excellent effect of
