| The bus black box system is the research target in my article,the design and realization of the bus black box system were thoroughly studied.In the light of modularization and structuring idea,the article gives out the whole design scheme of the system at first,then the simple introduce of the main substance, design requirement , technique target along with the present situation and the development foreground at home of the bus black box system .The article then separately penetrate into the component module of the system.First the design and the realization of the black box module is elaborateed ,which consist of the hard materials choice and the concrete level conversion electric circuit and the hardware electric circuit . On the base of it, software programming begins.Afterwards the article expound to the warning module which Consist of the alarm device component pictures , the hard materials choice and the hardware electric circuit . On the base of it,gives out the software realization of relevant alarm means.Finally CAN's net modular is introduced,it has no exception to give out the software and hardware realization of the whole modular . the modular is a link of the whole system , up to this point , the black box module and the warning module is connected by the CAN's net modular and work well. |
