Embodiment 1
[0039] This embodiment discloses a non-contact trigger elevator calling method. The non-contact trigger can be a hand, a foot or other objects. The specific content of the method will be described below by taking the foot trigger as an example.
[0040] The elevator includes a distance sensor, and the calling method divides the triggering process into three stages: initial stage-rising stage-triggering stage (see figure 2 ).
[0041] Initial stage (that is, the first time period, shown as t1 time period in the figure): If there is no obstruction within the range of L1, it is determined that the initial stage is established, and the blocking condition of foreign objects is filtered.
[0042] The preferred initial stage t1 time period is 20ms;
[0043] Rising phase (that is, the second time period, represented as t2 time period in the figure): During the process of the foot approaching, the distance between the foot and the sensor keeps decreasing in the comparison of the valu...
Embodiment 2
[0050] This embodiment discloses a device for non-contact triggering of an elevator calling method, and the triggering object may be a hand, a foot or other objects. Taking the foot sensor call as an example, the foot sensor call (uplink sensor call 2 and / or downlink sensor call 3) is arranged on the landing side below the ordinary call 1, about 10cm away from the ground (see figure 1 ). The structures and functions of the uplink induction calling 2 and the downlink induction calling 3 are basically the same except for the difference in direction arrows. For the bottom floor of the elevator, only the uplink induction call is required; for the top floor of the elevator, only the downlink induction call is required; for the middle floors, both uplink induction call and downlink induction call can be configured or only one uplink induction call or one downlink induction call can be configured according to the frequency of use Inductive call. The uplink induction calling 2 and / o...
Embodiment 3
[0052]The sensing range of a single sensor is usually conical, or even point-like ( Image 6 ).
[0053] The characteristics of the one-leg approach call are as follows: first, when a person raises one foot to approach the call, the time without affecting the balance is usually about 100ms. The longer the stay time, the harder it is to maintain balance. Usually, a more practical working condition of foot induction calling is that people hold objects with both hands, so the time for one foot to be kept stable and lifted will not be too long; second, in such a short period of time, passengers are required to focus on one foot It is usually difficult to complete the induction triggering at one point. The feet, especially the toes, usually deviate from the induction center to a certain extent; Usually approach the call from both sides of the call, and in the standing working condition, usually stand in front of the call, and approach the call from the bottom to the top with the t...
