The Design And Analyze Of Wireless Monitor Network For Railway

With the Perfection and development of WLAN, it has found wide application in every aspect of our society. WLAN, as a new type of wireless net technology, has its overwhelming Superiority in the net consisting of military communication. In view of the requirement of the information network consisting, how to apply the WLAN technology to railway safety information network will be a very urgent and necessary. Task study the request sets off from the project originally , discuss the actual need that the signal transfers under complicated geographic conditions , transfer having brought forward one kind of wireless paragraph division, fiber-optical concentrates the network assembling forming a train of thought, to transfer monitoring information. In the paper, the author has resolved the problem between video information collecting and the network transmission under complicated landform. Has discussed system frequency and given one kind of lessening to reduce oneself disturbs; According to the actual testing, put the wireless channel error on the theory discussion, and gave a method of network optimization. The results show that, the scheme designs to be able to satisfy the network designing need and the parameter optimization can improve the network function.Compared with other tradition design, this system has been needless to lay large amount of line cable in construction, and cost less. The project has resolved the difficult problem monitoring data transmission along the rail line successfully, has certain social value in the field of the railroad safety. To forming lower peculiar environment networks such as express highway, border defense, system also has reference value at the same time.
