Embodiment
The platform of the national emergency communication of merging towards the world, emphasis will develop advanced moving communication satellite and high-speed wideband and the multimedia communication satellite based on ATC technology.The supportability of General Promotion country aspect emergency communication, builds the backup measure of national key telecommunications network.Realize communication network intellectual education ability and the managerial skills of real Incorporate.Promote the operation mode that China is emergent and commercial operation is integrated.Utilize ATC procotol technology, as long as your hand-held set your notebook in other words, which network you can find, and it can lead to.With this, in conjunction with above accompanying drawing, following examples are by the unitary construction of railway anti-disaster emergency satellite communication command system and the description of system dynamic duty that launch in detail the utility model and relate to.
Setting up based on the emergent railway anti-disaster true situation very first time being conveyed to emergency management and rescue center of native system, and can carry out long-range " floor manager " by wired or wireless call form, to reach fast reaction, to process the object putting in place.For realizing this purpose, utilizing satellite communication to set up railway anti-disaster emergency commading system is the important means that ensures railway transportation in wartime and railway recovery commander and contact.The enforcement of these means is to set up rapid, safe, secret, accurate, unimpeded railway anti-disaster emergency satellite communication command system particularly important behave in the present and the future's railway transportation work.
For example Fig. 1 is the topological schematic diagram of the railway anti-disaster emergency satellite communication command system that relates to of the utility model.It has comprised disparate networks connection device of the prior art, as router, switch, fire compartment wall, comprehensive server, and and the VOIP/ voice gateways of PSTN net connection etc.Here said comprehensive server can be panel computer of the prior art or terminal server; It can for client provide disaster monitoring information storage, browse, the integrated service such as statistics, analysis and prediction.Here saidly can make command centre realize voice communication by being connected to telephone set on switch and the telephone set of disaster field to the utilization of VOIP/ voice gateways.
For example Fig. 2, Fig. 3 are to being arranged on I/O motherboard circuit in video server design circuit mainboard figure again again.According to practice, the technological difficulties that will solve concentrate on aspect the fast processing and transmission of video information at system and in realizing.The transmission that adopts IP technology to realize video information is a feature of the technical scheme that relates to of the utility model, and IP/Modem is that Internet protocol/modulator-demodulator is the bridge being situated between between ground satellite station and switch.Native system utilizes FPGA to realize the video compression of wavelet algorithm and transmits at satellite channel, system adopt two-dimensional wavelet transformation and fast zerotree encoding algorithm monitoring site image is carried out to compressed encoding, then via satellite transmission to remote command control centre.Two-dimensional wavelet transformation and fast zerotree image have just been removed image redundancy spatially, and adjacent image is not utilized in the correlation of time domain.In order to improve the performance of supervisory control system, further improve compression ratio, and reach the object of real-time monitoring, must further remove the redundancy of image sequence in time domain.Block motion compensation technology has been widely used in the coding of video sequence image as the means of time domain prediction.In order to remove time domain redundancy, can first do motion compensation to sequence image, then predicated error is made to Coding with Wavelets, but this scheme increases system complexity greatly.In order to make wavelet transformation directly get involved interframe encode, and do not make system hardware too complicated, the utility model according to one be easy to hard-wired 3 D wavelet transformation Sequence Image Coding algorithm.And in advance mutual alignment, the annexation of each functionalization module on mainboard are calculated and set and put in place, for example the binding post Vin11 of the modular circuit in video input circuit mainboard is connected with the video inputs of described switch by interface P2; Binding post IOR34, the IOG32 of the modular circuit in video output circuit mainboard, IOB28 are connected with the CON-out interface of described video output circuit mainboard respectively.Then, then through space fast two-dimensional wavelet transformation verify through FPGA, the sequence image that the setting of sort circuit mainboard can make video image is elapsed time dimension Harr wavelet transformation first,, thereby completes the 3 D wavelet transformation of sequence image.The quick zerotree encoding algorithm of sub-band images utilization 3 D wavelet transformation being obtained is encoded and with the VLSI structure of 3 D wavelet Sequence Image Coding, video image is carried out to emulation and logic synthesis, thereby obtains the scene of taking precautions against natural calamities or command on-the-spot fact.In concrete practice, the modular circuit in video input/output motherboard circuit is respectively that SAA7113 or ADV7123 are reasonable selections.
In sum, the railway anti-disaster emergency satellite communication command system that utility model relates to is the Command Information System of emergency satellite communication fast of the processing of integrated use audio frequency and video, the network communications technology, this system should realize all standing transmission of audio frequency and video in emergency network, meet the demand that railway emergency repair covers to wireless audio and video the wired audio frequency and video of whole network, and applicable to the application of station, goods yard and other industry.In the time that railway generation natural calamity or accident etc. affect the emergency of railway transportation, field rescue staff can be directly connected to by telephone set the leaders of Police Command Center, meeting room, office, timely understanding field condition that like this could be real, also utilize this cover system to set up interim intercommunication facility simultaneously, make field personnel complete internal communication by wireless, wired mode, guarantee to carry out in real time rescue command.
