Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further illustrated, but not as the foundation limited the present invention.
Embodiment.Elevator speed control method, runs elevator and is divided into startup speed-raising stage, constant velocity stage and deceleration stop layers stage; The described deceleration stop layers stage is occurred by the triggering apart from node; And the speed-time curve starting speed-raising stage and deceleration stop layers stage is fixing.The triggering method of described distance node is: bottom lift car, set out the laser transimitter that light direction is level, and multiple distance node is set on hoistway, described comprising apart from node is arranged on the blind hole on hoistway and the optical receiver in blind hole, and every 2 corresponding floors of distance node, 2 distance nodes of each floor lay respectively at above and below floor, the triggering of distance node when being respectively used to uplink and downlink, when elevator cage operation is to distance objective position certain distance, the emergent light of laser transimitter shines into blind hole, optical receiver is made to receive optical signal, thus trigger the generation in deceleration stop layers stage.Multiple perpendicular straight arranged location correction node is also provided with in described hoistway, location correction node is made up of the optical receiver in blind hole and blind hole, after the deceleration stop layers stage of elevator triggers, laser transimitter shines into each blind hole one by one, and make optical receiver receive optical signal, when optical signal received by each optical receiver, just can monitor the actual position of lift car, by this actual position with the theoretical velocity curve in deceleration stop layers stage is carried out to the theoretical position value that integration obtains and compares, as produced difference, then control towing machine fine setting rotating speed, thus lift car accurate stop layers in continuous error modulation can be made.Described each distance node is only when there is calling signal in the floor that this distance node is corresponding, and the triggering of this node could really come into force, and this triggering of no person will be left in the basket.Because elevator is to when running first floor, its running velocity is all adopt independent master mode, thus the solution of the present invention be also all for 2 floors more than operation scheme.
Mode of operation of the present invention (for 7 floor rooms):
Be provided with the Top Runby node of 3rd floors in the hoistway of elevator between 1-2 building, be provided with the Bottom Runby node of 1st floor and the Top Runby node of 4th floors between layer 2-3, by that analogy, as shown in Figure 1.
When lift car is parked in 1st floor, now there is calling signal in N building (not comprising 2), then elevator starts according to fixing formula, first the startup speed-raising stage arrives constant velocity stage again, the S1 to S (N-1) that constant velocity stage triggers all cannot come into force, therefore the deceleration stop layers stage can not be triggered, until elevator cage operation is to triggering SN, the then deceleration stop layers stage starts, in the deceleration stop layers stage, the operation of car constantly triggers range correct node again, so both can monitor the actual position of lift car, by this actual position with the theoretical velocity curve in deceleration stop layers stage is carried out to the theoretical position value that integration obtains and compares, as produced difference, then control towing machine fine setting rotating speed, thus lift car accurate stop layers in continuous error modulation can be made.
In like manner, when lift car is parked in 7th floors, now there is calling signal in N building (not comprising 6), then elevator starts according to fixing formula, first the startup speed-raising stage arrives constant velocity stage again, the D7 to D (N+1) that constant velocity stage triggers all cannot come into force, therefore the deceleration stop layers stage can not be triggered, until elevator cage operation is to triggering DN, the then deceleration stop layers stage starts, in the deceleration stop layers stage, the operation of car constantly triggers range correct node again, so both can monitor the actual position of lift car, by this actual position with the theoretical velocity curve in deceleration stop layers stage is carried out to the theoretical position value that integration obtains and compares, as produced difference, then control towing machine fine setting rotating speed, thus lift car accurate stop layers in continuous error modulation can be made.
When having multiple floor to have calling signal simultaneously, it is impossible simultaneous that triggering due to distance node comes into force, there is a sequential in it, therefore its can trigger and come into force first distance node time to reduce speed now stop layers, thus can stop successively according to the approach order of lift car, without the need to precalculating, simply effectively.
