Research On Information Supervision And The Speech Communication System In Specialize Train

With the development of measurement and network technologies,ITS systems could be implemented with more strategies .Vehicle information is always considered as essential element and main contributor in ITS to provide relevant information for strategy determination, driving, safty, information acquisition,ememergency vehicle safty, reliability verficition and so on. Nowadays, to fetch more complete and accurate macro & micro vehicle information,lots of up-to-date technologies and results are applied in Vehicle Information Acquisition Systems.However,some flaws underlie in the system construction and the performance could not meet specific requirements completely.Based on investigation of sensor technology, Zigbee technology and speech communication, the feasibility and advantage of applying wireless sensor network on traffic information collection are data-voice compatible system.In this paper,a new method is proposed to construct advanced Traffic Information Acquisition System. In terms of hardware,circuit design is implemented,where Zigbee chip MC13213 is employed,which is very useful to solve communication blind areas and especially railroad, highway, oil-field, the mineral mountain etc. Particularly for the train of the special mission, this method not only economic valid, but also unique by now.This paper mainly studied to carry out the hardware design base on the Zigbee network. Demonstrated by tests, because of low costs and power supply, the performance is highly Valued in terms of the reliability, compatibility and being open. Hence it could be applied on information collection, intelligent vehicle, and various sensor based information acquisition systems.
