Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0033] Such as figure 1As shown, the bus integrated positioning information device includes a central control unit 1, a display unit 2, a communication interface 3, a control key 4, a vehicle speed mileage sensor 5 and a GPS module 6 to transmit signals to the central control unit 1 through the integrated position data module 7; The central control unit 1 transmits the processed signal to the dispatching information center through the communication interface 3 and the communication module. The communication module connected to the communication interface 3 adopts GPRS or CDMA-1X module.

[0034] see figure 2 , the integrated position data module 7 is composed of four parts such as the storage module 8 of the scheduled running stroke and its direction data, the parameter selection (and validity discrimination) sub-module 9, the trajectory dat...

Abstract

A comprehensive positioning device of bus consists of central control unit, display unit, communication module and control key, transducer of bus speed mileage and GPS module .It features that signal is transmitted to central control unit by comprehensive position data module and processed signal is transmitted to information center by central control unit through communication interface and communication module.

Description

technical field [0001] The invention relates to vehicle positioning information technology, in particular to a comprehensive bus vehicle positioning information device controlled by a computer program. It belongs to the field of traffic information electronic technology. Background technique [0002] In the prior art, the GPS positioning device and the "mileage positioning" vehicle terminal system are mainly used for passenger vehicle positioning and information collection, processing and transmission based on positioning. But all can not satisfy the requirement of bus management demand and vehicle-mounted information device. The main reason is that the existing GPS positioning device is limited by the objective conditions of urban road traffic, such as high-rise buildings on both sides of the road, serious direct occlusion and image interference, or roadside trees are shady, or serious occlusion attenuation of overpasses and tunnels, The GPS satellite positioning system r...
