Research Of Taxi Location System Based On CDMA

This paper introduced a taxi location system which combined with several technologies such as GPS, digital communications, computer network and geographical information system. This system is provided with many functions, it can monitor, attempt and manage the taxi. At the same time, this system insured the chauffeur and his property in safety. This taxi location system is the way to realize the effective information management.This study based on the requirement of taxi location system, adopted a novelty method in design after reference to the location system which popularity currently. We selected the CDMA network as the wireless communication in this project, combined whit the technologies of domain name server and Internet application, the mobile station can communicated with management center. The location information be adopted from the GPS receiver at currently, if the GPS signal is too faintness to be received by the GPS receiver, we can ask for the GPSOne as assistant of GPS receiver. This method insured the location information of the vehicle effective as long. The mobile station can send the taking note of driver to management center, these data provided the foundation of the customs bureau for the business tax, this technology induced the management of revenue in concision and precision.This paper investigated the ABC of GPS technology, the CDMA network and the GPSOne at first, also illuminated the method of wireless joint about communication and the characteristic of the internet link. Then, we introduced the method of hardware design and software design particularity, described the functions of several comparatively independence parts, such as the control of GPS receiver, the drive of CDMA communication module, the operation of Liquid Crystal Display. Lastly, we introduced the function and design method...
