The workflow of elevator mobile communication covering system of the present utility model comprises up step and descending step:
Descending step:
Up step:
Retransmitting antenna 34 is forwarded to donor antenna 33 with the terminal signaling that receives, and sends to information source antenna 32 by donor antenna 33;
Therein among embodiment, described power controller 31 comprises power control module 311 and range finder module 312,31 pairs of source signals of described power controller carry out the step of power control, be specially: the range finder module 312 in the power controller 31 is measured donor antenna 33 to the distance of information source antenna 32, is adjusted the power output of the signal of described information source antenna transmission according to described distance by power control module 311.
Present embodiment by adjusting the power output of information source antenna 32, reduces in lift car by 2 terminal signaling to the interference of source signal.
Among embodiment, described distance is directly proportional with the power output of the source signal that described information source antenna sends therein.In the present embodiment, distance and power output are directly proportional, then the distance when lift car 2 and range finder module 312 is more little, then the power output of information source antenna 32 is more little, the decline of power output, then the link load at the terminal to base station receiver of lift car 2 can increase, thereby also disturbs source signal even avoid when terminal is launched with minimum power when too small because of link load.And when the distance increase of lift car 2 with range finder module 312, then improve the power output of information source antenna 32 simultaneously, and reduce the link load of the terminal to base station receiver of lift car 2, strengthen the good coverage effect of back maintenance to guarantee the space link loss.

Among embodiment, described distance is inversely proportional to the decay of described electrically controlled attenuator therein.Because the decay of power controller 312 is more big, then the output of information source antenna 32 is more little, therefore the distance when lift car 2 and range finder module 312 is more little, then increase the decay of power controller 312, thereby make the power output of information source antenna 32 descend, then the link load at the terminal to base station receiver of lift car 2 can increase, thereby also disturbs source signal even avoid when terminal is launched with minimum power when too small because of link load.And when the distance increase of lift car 2 with range finder module 312, then reduce the decay of power controller 312 simultaneously, thereby improve the power output of information source antenna 32, reduce the link load of the terminal to base station receiver of lift car 2, to guarantee that the space link loss strengthens the back and keeps good coverage effect.
Therein among embodiment, the step of adjusting the power output of the source signal that described information source antenna sends according to described distance is specially:
When described donor antenna to the distance of information source antenna is less than default distance threshold, power control module reduces the power output of the source signal of described information source antenna transmission according to predetermined strategy, when described donor antenna to the distance of information source antenna during more than or equal to default distance threshold, the power output that power control module is controlled the source signal that described information source antenna sends is maximum power.As an example, power controller 31 comprises power control module 311 and range finder module 312, and power control module 311 comprises electrically controlled attenuator 3111 and supervising device 3112, then:
When the distance of lift car 2 and information source antenna 32 surpasses default distance threshold, because range finder module 312 is arranged on same horizontal plane with described information source antenna 32, therefore the distance of lift car 2 and information source antenna 32 is the distance of lift car 2 and range finder module 312, power controller 3111 not decay this moment, power output with maximum covers lift car 2, when lift car 2 operations more and more approach near information source antenna 32, and after arriving the distance of setting, electrically controlled attenuator 3111 beginnings add high attenuation according to the strategy that is set in the supervising device 3112, thereby increase terminal to the link load of source device, also disturb source device even avoid when terminal is launched with minimum power when too small because of link load, can not be more approaching until arriving its maximum attenuation degree or lift car 2, when lift car 2 from the nearest position of distance information source antenna 32 away from the time, electrically controlled attenuator 3111 beginnings reduce decay according to the set strategy that is set in the supervising device 3112, guaranteeing that the space link loss strengthens the back and keeps good coverage effect, the distance of undamped or lift car 2 and information source antenna 32 is greater than the measuring range of range finder module 312 up to electrically controlled attenuator 3111.
The above embodiment has only expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
