Formula, due to train metal car body stop, to compartment in signal attenuation it is serious, it is impossible to the letter of high bandwidth is provided
Breath service, because passenger's density is especially big in compartment, passenger needs the wireless network of high bandwidth, particularly
Subway, because the online number of peak value is huge, can not often get through operator's phone in peak time；Or train
Under full load conditions, average to have more than 5 people per square meter, human body is to wireless signal serious shielding, it is impossible to reach
High-quality wireless coverage effect.
The content of the invention
It is used for train and terrestrial wireless bridge-set and side wireless communication it is an object of the invention to provide one kind
Method, for solving the congestion of train operation peak period wireless data service, covering effect of signals in the prior art
The technical problem of difference.
To reach above-mentioned purpose, technical scheme proposed by the invention is：
One kind of the present invention is used for train and terrestrial wireless bridge-set, and it includes：Communicate wirelessly to each other

Vehicle-mounted AP and car antenna are included, the trackside radio bridging device includes trackside AP and trackside antenna,
Radio bridging device communicates interconnection with in-vehicle wireless communication system on the car, the trackside wireless bridge tipping
The interconnection that communicated with ground base station is put, wireless data service is provided for passenger.
Wherein, radio bridging device includes text, Voice ＆ Video for the service that passenger provides on the car
Service.
Wherein, radio bridging device is located at train head and the tailstock on described car.
Wherein, described trackside radio bridging device is located at train driving by tunnel or track, and
And provided with some groups of trackside radio bridging devices, when train passes through, by one group of nearest trackside wireless bridging
Device is communicated interconnection with the onboard wireless bridge-set, and wireless data service is provided for passenger.
It is used for the side wireless communication of train and terrestrial wireless bridge-set using described in as above any one
Method, it includes：Be installed on the car on train radio bridging device with located at train through some in way
The step of trackside radio bridging device is using segmentation interconnected communication.
Compared with prior art, the invention is used for train and terrestrial wireless bridge-set and side wireless communication
Method, it can allow the covering of row in-vehicle wireless network to provide high band by disposing radio bridging device in train
Wide Connection Service, train head, tailstock deployment wireless vehicle ground access point AP, it is to avoid train leads to ground
The limitation of telecommunications services, train head, the tailstock are two-way with ground communication wireless bridging, are prevented effectively from unidirectional logical
Letter is obstructed and influences intra-train communication demand for services.
Brief description of the drawings
Structural representations of the Fig. 1 for the present invention for train and terrestrial wireless bridge-set.
Embodiment
Below with reference to accompanying drawing, give the present invention further elaboration.
Accompanying drawing 1 is referred to, in this embodiment, the one kind is used for train and terrestrial wireless bridge-set,
It includes：Radio bridging device 1 and some trackside radio bridging devices 4 on the car communicated wirelessly to each other, 5,
6、7.Wherein, radio bridging device 1 includes vehicle-mounted AP11 and car antenna 12, institute on described car
Stating trackside radio bridging device 4 includes wireless bridge tipping on trackside AP41 and trackside antenna 42, the car
1 is put to communicate with in-vehicle wireless communication system 2 interconnection, the trackside radio bridging device 4,5,6,7
Communicated interconnection with ground base station, and wireless data service is provided for passenger.Vehicle-mounted AP11 and trackside AP41
It is the wireless access point apparatus for track traffic.
In this embodiment, illustrate only by taking the vehicle head part of train 100 as an example, tail part is again provided with car
Radio bridging device 1, located at train by way of tunnel or the side of track 3 trackside radio bridging device 4,5,
6th, 7, in other embodiments, can be according to communication only by taking which part trackside radio bridging device as an example
Need to add more trackside radio bridging devices.
Wherein, radio bridging device 1 includes text, audio for the service that passenger provides and regarded on above-mentioned car
Be taken in small doses at short intervals business, and other kinds of web services.
It should be noted that radio bridging device 1 is located at train head and the tailstock on described car.Root
According to for the communication system of the track traffics such as subway, it is necessary to according to This train is bound for XXX carry out different channels it is wide
The distribution of degree.
Specifically, described trackside radio bridging device 4,5,6,7 is located at train driving by way of tunnel
