Abstract
The invention discloses a Beidou satellite-based inter-vehicle time synchronization system. According to the system, a Beidou global positioning system (GPS) dual-mode synchronization system is adopted and a multi-synchronization source adaptive synchronization technology is adopted to synchronize with an external synchronization clock signal. When the Beidou GPS dual-mode synchronization system normally receives a GPS satellite signal, a Beidou signal and an inter range instrumentation group-B (IRIG-B) time code synchronously, the second synchronization signal transmitted by the GPS and time information serve as the external time reference of a master clock and others serve as hot spares; when the GPS is out of synchronism and has an effective Beidou signal, the second synchronization signal transmitted by the Beidou satellite and the time information serve as the external time reference of the master clock; and when the GPS and the Beidou are both out of synchronism, an iopus private internet gateway-B (IPIG-B) interface receives a time signal optimally selected to serve as the external time reference of the master clock. The system has a reasonable structure, and can realize the vehicle time synchronization control of a vehicle networking system, particularly the time synchronization control of vehicles in movement.
Description
Technical field
The present invention relates to the clock synchronization system between a kind of vehicle.
Summary of the invention
Summary of the invention
The object of the present invention is to provide a kind of rational in infrastructure, good working effect based on the clock synchronization system between the big-dipper satellite vehicle.
Technical solution of the present invention is:
A kind of based on the clock synchronization system between the big-dipper satellite vehicle, it is characterized in that: adopt Big Dipper GPS bimodulus synchro system, adopt many synchronisation sources self-adaptation simultaneous techniques, synchronous with outer synchronizing clock signals; When Big Dipper GPS bimodulus synchro system is simultaneously normal when receiving gps satellite signal and Big Dipper signal and IRIG-B time-code, GPS sends second synchronizing signal and temporal information as the external time reference of major clock, other are as hot reserve; When the GPS step-out and when effective Big Dipper signal is arranged, the Big Dipper sends second synchronizing signal and temporal information as the external time reference of major clock, when the GPS/ Big Dipper all during step-out, IPIG-B interface time of reception signal is preferably as the external time reference of major clock.
Described synchro system is the clock synchronization system in the motor racing.
The present invention is rational in infrastructure, can effectively realize the automobile time synchronized control of car networked system, the particularly time synchronized of automobile control in the motion.
The invention will be further described below in conjunction with embodiment.
In the prior art, how to realize time synchronized control in the vehicle synchro control, particularly motor racing of car networked system, be technician's problem of groping for a long time, but breakthrough is not arranged always.
