In case of the solution according to the inven-tion, when sporter runs on a treadmill or walks, if need to slow down, sporter can Slow Down or while hand steered treadmill handle reverse pedaling running band forward, now, because the leg speed advanced in years of sporter is lower than the speed of service backward of treadmill belt, the leg that treadmill belt pulls sporter to a certain extent runs backward.In this case, if with the foothold of sporter for benchmark, then treadmill belt tension detector can detect that the treadmill belt tension force in foothold front is less than the treadmill belt tension force at foothold rear, this shows that sporter is intended to reduce the speed of treadmill, now motor speed controller just directly can reduce the rotating speed of motor according to the testing result of treadmill belt tension detector, and does not need sporter to carry out manual operation.Otherwise, if need to accelerate, then sporter can hasten one's steps or trample treadmill belt backward while hand steered treadmill handle, now, because the leg speed advanced in years of sporter is higher than the transmission speed of treadmill belt, the leg of treadmill belt passive movement person to a certain extent pulls and runs backward.In this case, if with the foothold of sporter for benchmark, then treadmill belt tension detector can detect that the treadmill belt tension force in foothold front is greater than the treadmill belt tension force at foothold rear, this shows that sporter is intended to improve the speed of treadmill, now motor speed controller just directly can improve the rotating speed of motor according to the testing result of treadmill belt tension detector, and does not need sporter to carry out manual operation.It is to be noted about this point, no matter be need to accelerate or slow down, sporter hasten one's steps (backward pedal treadmill belt) or Slow Down (forward pedaling running band) time amplitude all without the need to excessive, as long as described treadmill belt tension detector can detect the tension variation before and after foothold.Otherwise, especially when because needs slow down and Slow Down, amplitude is excessive may cause sporter to drop from treadmill.
In the preferred embodiment of above-mentioned automatic speed governing device, when described treadmill belt tension detector detects that the treadmill belt tension force in the foothold front of sporter is greater than the treadmill belt tension force at foothold rear and difference therebetween reaches certain threshold value, described motor speed controller just orders described motor to accelerate, and wherein, when described treadmill belt tension detector detects that the treadmill belt tension force in the foothold front of sporter is less than the treadmill belt tension force at foothold rear and difference therebetween reaches certain threshold value, described motor speed controller just orders described motor deceleration.
In the ideal case, when sporter runs on a treadmill or walks, the treadmill belt tension force before and after its foothold should be roughly equal.Therefore, if the treadmill belt tension force before treadmill belt tension detector detects foothold is greater than the treadmill belt tension force after foothold, then show that sporter is intended to accelerate; Otherwise, if the treadmill belt tension force before foothold is less than the treadmill belt tension force after foothold, then show that sporter is intended to slow down.But due to the individual difference of each sporter, the Tension Difference before and after foothold may be different.Therefore, for each sporter, above-mentioned threshold value also may be different.Such as, for some sporter, it likes being pulled running or walking by treadmill belt at ordinary times, treadmill belt tension force under normal circumstances before its foothold is less than the treadmill belt tension force after foothold, even if when hastening one's steps because of wanting to accelerate, the treadmill belt tension force before its foothold also may be slightly less than the treadmill belt tension force after foothold.In this case, for this sporter, threshold value during above-mentioned acceleration is exactly negative value.Certainly, this special circumstances can be solved by parameter setter of the present invention, specifically refer to detailed description hereafter.
In the preferred embodiment of above-mentioned automatic speed governing device, described treadmill belt tension detector comprises multiple treadmill belt tension pick-up, described treadmill belt tension pick-up is arranged on the main frame of described treadmill, or be arranged on described treadmill, near treadmill belt front and rear housings on, or be arranged on described treadmill belt, or be arranged on the running board below described treadmill belt, for the treadmill belt tension force in the foothold front and rear of detecting sporter.When described treadmill belt tension pick-up is arranged on treadmill belt, it preferably adopts contact tension pick-up.When described treadmill belt tension pick-up is arranged on described main frame, housing or running board, it preferably adopts non-contact tension sensor.These sensors can be arranged on comparatively dense ground, to cover each position of treadmill belt, thus which position of foothold on treadmill belt of no matter sporter, described sensor can detect the treadmill belt tension force before and after the foothold of sporter exactly.
