Description
Technical field
The present invention relates to a kind of vehicle timesharing method for limiting speed based on car wireless terminal.
Background technology
Along with increasing of newly-built, highway, national highway and the international road again revised in recent years, greatly alleviate traffic pressure, accelerate vehicular circulation speed, improve carrying capacity.But the Integral lifting of road conditions but brings another problem, overspeed of vehicle problem, a large amount of fact proved, travelling at high way super speed is one of major traffic accidents chief reason, and the casualties caused therefrom and property loss are shocking especially.Overspeed of vehicle oversight mechanism, to the certain deterrent effect of the driver exeeded the regulation speed, can add point penalty with economic penalties, revokes the modes such as driving license, forces driver to observe traffic rules and regulations, can the incidence of reduction accident to a certain extent.
At present for the hypervelocity behavior of vehicle in each period, mainly contain two kinds of supervision schemes:
1, by vehicle monitoring platform according to the different time periods, speed limits different below vehicle-mounted wireless monitoring terminal, car wireless terminal, according to new speed limit, judges whether vehicle is in overspeed condition.When vehicle reaches speed limit, car wireless terminal reminds driver to exceed the speed limit, and by the vehicle monitoring platform of hypervelocity information reporting, after vehicle monitoring platform statistics hypervelocity information, carries out corresponding punishment to driver.This scheme can accomplish to monitor comparatively accurately for the section that network signal is good, but for the section that network signal is bad, because vehicle cannot receive the order that vehicle monitoring platform issues timely, new speed limit cannot be adopted, carry out contrast to judge, easily cause hypervelocity Information Statistics inaccurate.
2, by vehicle monitoring platform according to the different time periods, extract the speed limit that this section is different, according on automobile wireless monitor terminal send out current longitude and latitude and speed, judge that whether vehicle is in this section, and judge whether to be in overspeed condition.When vehicle reaches speed limit, vehicle monitoring platform issues suggestion voice to automobile wireless monitor terminal, reminds driver to exceed the speed limit.After vehicle monitoring platform statistics hypervelocity information, corresponding punishment is carried out to driver.This scheme can accomplish to monitor comparatively accurately for the section that network signal is good, but for the section that network signal is bad, because vehicle cannot upload instant vehicle longitude and latitude and speed, vehicle monitoring platform cannot judge whether vehicle is in overspeed condition immediately, also cannot the hypervelocity information of calculating vehicle.
