The purpose of this utility model provides a kind of power emergency communication network system, can adopt the most rational communication mode, emergency communication between the inner He Da of the feasible region district, and, can realize still can carrying out emergency communication by portable terminal in the situation that satellite-signal can't cover or even the ground communication module can't cover.
In order to realize above purpose, the utility model is achieved through the following technical solutions:
A kind of power emergency communication network system comprises by radio communication: be arranged on broadband satellite in the space, be arranged on ground several ground communication modules and several portable terminals; Described ground communication module the communicating by letter of maintenance and broadband satellite and PERCOM peripheral communication command centre in motion process, this ground communication module is also by wireless with outside power telecom network node communication; Described portable terminal and ground communication module communication nearby.
Be provided with some data link channel in described each ground communication module, described some the data link channel route that backups each other, these some data link channel respectively with broadband satellite, portable terminal and adjacent other ground communication module communications.
The data link channel of described ground communication module and wideband satellite communication are relayed to the multi-service transmission system of PERCOM peripheral communication command centre again through broadband satellite, consist of the wideband satellite communication net.
Between described a plurality of ground communication module and mutual communication the between ground communication module and the PERCOM peripheral communication command centre, consist of wireless digital broadband private network.
Described wireless digital broadband private network carries out transfer of data by the band-spread wireless digital technology.
The signal cover of described ground communication module is 40 ~ 80km.
The signal cover of described portable terminal is 3 ~ 5km.
The utility model compared with prior art has the following advantages:
1, can adopt the most rational communication mode, the emergency communication between the inner He Da of the feasible region district,
2, can also realize still can carrying out emergency communication by portable terminal in the situation that satellite-signal can't cover or even the ground communication module can't cover.
Description of drawings
Fig. 1 is the theory diagram of a kind of power emergency communication network of the utility model system.
Embodiment
Below in conjunction with accompanying drawing, by describing a better specific embodiment in detail, the utility model is further elaborated.
As shown in Figure 1, a kind of power emergency communication network system comprises by radio communication: be arranged on broadband satellite 1 in the space, be arranged on ground several ground communication modules 2 and several portable terminals 3; Described ground communication module 2 keeps in motion process and the communicating by letter of broadband satellite 1 and PERCOM peripheral communication command centre, and this ground communication module 2 is also by wireless with outside power telecom network node communication; Described portable terminal 3 is communicated by letter with ground communication module 2 nearby.In the present embodiment, select the IPSTAR broadband satellite, its bandwidth general export can reach 40G, can satisfy and use the needs application, ensures the various demands of voice, image, data communication service; Ground communication module 2 is used the moving logical technology of satellites, so that in the process of ground communication module 2 (such as automobile) motion on carrier, can keep at any time and the communicating by letter of broadband satellite 1.
Be provided with some data link channel in each ground communication module 2, in the present embodiment, be provided with two data link channel, these two data link channel route that backups each other, it is communicated by letter with broadband satellite 1, portable terminal 3 and adjacent other ground communication modules 2 respectively.Thereby the data link channel of ground communication module 2 is communicated by letter with broadband satellite 1, is relayed to the multi-service transmission system of PERCOM peripheral communication command centre through broadband satellite 1 again, consists of the wideband satellite communication net; Between a plurality of ground communication modules 2 and mutual communication the between ground communication module 2 and the PERCOM peripheral communication command centre, consist of wireless digital broadband private network.
In the present embodiment, wireless digital broadband private network carries out transfer of data by the band-spread wireless digital technology, the band-spread wireless digital technology is the high-speed wideband data transmission technology on the wireless frequency modulation channel, its main thought be exactly the frequency response curve of wireless channel be non-flat forms mostly, in frequency domain, given channel is divided into many orthogonal sub-channels, use a subcarrier to modulate at every sub-channels, and each subcarrier parallel transmission.Like this, although total channel is non-flat forms, has frequency selectivity, but every sub-channels is relatively flat, and what carry out at every sub-channels is narrow band transmission, and signal bandwidth is less than the respective bandwidth of channel, therefore the just greatly interference between the erasure signal waveform, the spread spectrum main purpose is to improve the spectrum of carrier utilance, reduced the phase mutual interference between subcarrier, and this band-spread wireless digital technology is adopted generally militarily.Therefore, the signal cover of ground communication module 2 is 40 ~ 80km, and the signal cover of portable terminal 3 is 3 ~ 5km.
In the present embodiment, ground communication module 2 is arranged on the automobile, is assembled into the multichannel communication car.
Certainly, the instruction that also can accept to be correlated with too to portable terminal 3, ground communication module 2 realizes the transmitted in both directions of signal.
When using, electric power first-aid personnel taking portable terminal 3 is deeply on-the-spot, can communication distance be extended 3 ~ 5km in the zone that the multichannel communication car can't arrive, behind the video of collection site, data, the voice messaging, pass through Technology of Wireless Spread Spectrum, send to multichannel communication car nearby, the multichannel communication car is sent to outside power telecom network node nearby with relevant information, is sent to control center through powerline network again; If near unregulated power communication net node, then the multichannel communication car forms signal through the wideband satellite communication net or/and wireless digital broadband private network, and intelligence is routed on the multi-service transmission system of PERCOM peripheral communication command centre; If distant, and do not have satellite-signal to cover, then form temporary information spread spectrum junction network by many multichannel communication cars, because the spread spectrum repeater span of each car can reach 60 ~ 80km, therefore, can large capacity information be sent out by the mode of relay.Generally speaking, in the scope of 60 ~ 180km, be equipped with 1 ~ 3 multichannel communication car, 2 ~ 6 cover portable terminals 3 can be realized basic all standing.
In sum, a kind of power emergency communication network of the utility model system, can adopt the most rational communication mode, emergency communication between the inner He Da of the feasible region district, and, can realize still can carrying out emergency communication by portable terminal in the situation that satellite-signal can't cover or even the ground communication module can't cover.
Although content of the present utility model has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.After those skilled in the art have read foregoing, for multiple modification of the present utility model with to substitute all will be apparent.Therefore, protection range of the present utility model should be limited to the appended claims.
