Step C ": should according to the adjustment of the re-imaging length of the re-imaging length of first light pattern or second light pattern by the controller The running speed of runway to determine that an object is located at the position of the runway, and accordingly adjusts the running speed of the runway, Wherein the runway is at least divided into adjacent to one first sensing area of the first sensor and one adjacent to first sensing area One second sensing area.

33. the runway control method of treadmill as claimed in claim 32, it is characterised in that step C " further include:

When the re-imaging length and second light pattern of first light pattern re-imaging length at least one of them less than one first Default value, which determines that the object is located at first sensing area of the runway, and the controller accordingly increases the runway The running speed.

34. the runway control method of treadmill as claimed in claim 32, it is characterised in that step C " further include:

When at least one of them of the re-imaging length of the re-imaging length and second light pattern of first light pattern is greater than one first Default value, which determines that the object is located at second sensing area of the runway, and the controller accordingly reduces the runway The running speed.

35. the runway control method of treadmill as claimed in claim 32, it is characterised in that runway control method further include:

Step D ": according to the re-imaging length of first light pattern and the re-imaging length of second light pattern, determine the object position In the position of the runway, wherein the runway, which is at least divided into, provides one first detection zone and the neighbour of component adjacent to first signal It is bordering on the second signal and one second detection zone of component is provided.

36. the runway control method of treadmill as claimed in claim 35, it is characterised in that step D " further include:

When the re-imaging length of first light pattern is greater than the re-imaging length of second light pattern, which determines that the object is located at Second detection zone of the runway.

37. the runway control method of treadmill as claimed in claim 35, it is characterised in that step D " further include:

When first light pattern re-imaging length less than the second light pattern re-imaging length, the controller determine the object be located at should First detection zone of runway.
