Description
Technical field
The utility model belongs to elevator signal soverlay technique field, specifically, relates to a kind of numerical differentiation distribution system for elevator mobile communication quorum sensing inhibitor.
Background technology
Along with the fast development of urban construction, the elevator as one of degree of depth covering covers the Focal point and difficult point having become wireless network and covered.Elevator signal just existing herein covers scheme and compares explanation, indicates traditional solution Problems existing, proposes a kind of brand-new elevator solu, and set forth the technical advantage of new departure in conjunction with real case.
Along with the fast development of urban construction and the in short supply of urban land, rise residential and work in high level building get more and more, the region that the room in building, elevator, basement and civil air defense constructions and installations etc. are important, and mobile phone uses day by day frequent.But in elevator, quite weak, the more situation of place mobile phone signal such as basement is signal blind zone, cannot meet normal communication.And these places are also have higher traffic demand, so the wireless signal in these places must meet the demands.
The so-called degree of depth covers and just refers to that in building, deeper wireless signal covers, and refers generally in lift car, the Code in Hazardous Special Locations such as basement and civil air defense constructions and installations.The degree of depth in these places is covered there is suitable importance, except the weak problem of mobile phone signal wider in building can be solved, also solve the problem of telephone call difficulty when to run into emergency events in these Code in Hazardous Special Locations simultaneously, become a safeguard, the degree of depth therefore covered for lift car cell phone network covers engineering becomes a convenient project.
The architectural feature of elevator, becomes the blind area of quorum sensing inhibitor:
(1) elevator is generally positioned at the center of building, signal serious shielding;
(2) elevator hoistways is long and narrow, has tunnel effect, causes wireless signal loss to be accelerated;
(3) elevator is across firm armored concrete, and outdoor signal is difficult to cover whole hoistway;
(4) lift car is metal structure, has very strong screen effect to signal.
Add up according to relevant data, complaint about the poor signal in the place such as elevator, basement remained high in recent years, particularly rise residential, very large to the complaint amount in these places, due to the unique texture in these places, the difficulty that wireless signal is covered strengthens.It is a kind of during the degree of depth covers that elevator signal covers, and is also the problem that various places mobile operator and administration departments compare headache, also have impact on the brand image of operator to a certain extent.
Along with the development of Building technology, the application of New Building Materials, make building cover higher and higher, each metropolitan super-high buildings is increasing, and what architecture indoor quorum sensing inhibitor was become is more difficult, also more urgent, become the Focal point and difficult point that wireless network covers.
In prior art, the technical scheme covered for elevator comprises following three kinds:
One, in elevator hoistways, directional antenna is installed
Every 4 ~ 6 layers, one side platy directional antenna or Yagi antenna covering hoistway are installed in elevator hoistways, need feeder line to be fixed on the wall of hoistway.This mounting means will be constructed in elevator hoistways, except needing the cooperation of property, elevator company, also there is following problem: (1) fixes up an aerial wire, fixing feeder line, and difficulty of construction is large, the time is long; (2) jitter in elevator, when antenna, signal is better, away from dtr signal during antenna; (3) if elevator hoistways is longer, in hoistway, feeder loss strengthens, and also will increase the dry usage quantity active equipment such as putting; (4), if antenna comes off can cause potential safety hazard to elevator safety operation, there is antenna in the past and came off, caused the thing of elevator faults in later maintenance difficulty.
Two, fix up an aerial wire in Mei Ceng elevator hall
In order to solve the quorum sensing inhibitor in lift car, can fix up an aerial wire in elevator hall, to cover lift car.This scheme easy construction, without the need to the cooperation of elevator company, also can not impact elevator safety operation.If but multi-section elevator shares an elevator lobbies, adopt coverage effect in this way just undesirable, also will consider the impact of thickness on loss of signal of elevator shaft wall and elevator door in addition.In this method elevator, signal neither be very stable, and when antenna, signal is better, away from dtr signal during antenna.
Three, elevator trailing cable covers solution
Adopt netting twine or optical fiber as transmission medium, netting twine or optical fiber are bound in the trailing cable of elevator, distance connection unit and antenna are put into the top of lift car, such antenna moves up and down together with lift car, guarantees that antenna only covers lift car.Expanding element is placed in the Vertical Shaft for Light-Current of building, and master unit is then placed in base station machine room.It is more effective that the program compares the first two scheme, but still need to lay netting twine or optical fiber, and netting twine or optical fiber move with elevator, and easily distortion fractures, and brings suitable difficulty to later maintenance.
