In fruit, speed limit of the minimum result of numerical value as current road segment is selected.And the result is fed back into computer.According to above-mentioned side
Method, section speed limit corresponding to each group of road condition monitoring device is just obtained, 6 groups of road condition monitoring devices be present in the present embodiment, then
6 speed limits are calculated in data platform, and the speed limit for further selecting a numerical value minimum in this 6 speed limits is fed back to
Computer, the current speed limit of current road segment is so just obtained.
In the present embodiment, some groups of road condition monitoring devices are set, ensure the accuracy of result, in some groups of road condition monitorings
In speed limit corresponding to device, select numerical value it is minimum as current speed limit corresponding to current road segment, to be before first safely
Carry and provide rational driving suggestion for driver, reduce the generation of driving accident as far as possible.
Further, processor 1001 can call the program of the dynamic adjustment road speed limit stored in memory 1005,
Also perform following operate：
Detect whether current speed limit is less than default speed limit；
If current speed limit is less than default speed limit, outputting alarm information, to notify management corresponding to current road segment
Personnel.
In the present embodiment, it is default if the current speed limit of the present road obtained according to road condition data is 35km/h
The speed limit of present road is 45km/h, and current speed limit is less than default speed limit, then illustrates road conditions corresponding to present road very
It is bad, it may be possible to road ice layer thickness is thicker, wind-force corresponding to current road segment is larger, water accumulating volume corresponding to current road segment is more,
The surface evenness of current road segment is poor, caused by the current road segment more low factor of visibility, illustrates to drive a vehicle in current road segment
Degree of difficulty is larger, then needs to input warning information best friend's siphunculus platform, for arranging corresponding administrative staff to carry out traffic
Commander, with the generation to avoid traffic accident.
Further, processor 1001 can call the program of the dynamic adjustment road speed limit stored in memory 1005,
Also perform following operate：
The difference between the speed limit that the current speed limit and preset display screen are currently shown is detected whether more than default
Threshold value；
If the difference between the speed limit that the current speed limit and preset display screen are currently shown exceedes predetermined threshold value,
The current speed limit is shown in preset display screen.
In an alternate embodiment of the present invention, for example, the speed limit that computer receives is 69km/h, then the speed limit is detected
Whether the difference of the speed limit shown with current display screen exceedes predetermined threshold value, and (for example, threshold value is arranged to 10km/h, threshold value is set
Putting can be modified according to actual conditions, not be limited herein), if for example, the speed limit that current display screen is shown is 89km/h,
The difference for the speed limit that the speed limit of current selected is shown with current display screen has reached 20km/h, then by the speed limit of current selected
Value 69km/h renewals are shown on display screen, display screen and current road segment entrance at a distance of pre-determined distance, such as set this default away from
From for 500m.As shown in figure 3, Fig. 3 is the schematic diagram of a scenario that display screen of the present invention shows the embodiment of speed limit one.
In another optional the present embodiment is invented, if the speed limit of current selected be 69km/h, detect the speed limit and
Whether the difference for the speed limit that current display screen is shown exceedes predetermined threshold value (for example, threshold value is arranged to 10km/h, the setting of threshold value
Can be modified according to actual conditions, be not limited herein), if for example, the speed limit that current display screen is shown is 75km/h, when
The difference for the speed limit that preceding selected speed limit is shown with current display screen is 6km/h, then need not be to the current display of display screen
Speed limit be modified, speed limit 75km/h is still shown on display screen.
In the present embodiment, after current speed limit is obtained according to road condition data, current speed limit is shown with display screen
Speed limit be compared, only the difference between the speed limit that current speed limit and display screen are shown exceedes predetermined threshold value
When, just the renewal of current speed limit is shown on display screen, otherwise the speed limit of the current display of display screen is not modified, this
Sample one, avoid frequently to showing that the speed limit of screen display is modified.
Further, processor 1001 can call the program of the dynamic adjustment road speed limit stored in memory 1005,

The speed limit of present road is 45km/h, and current speed limit is less than default speed limit, then illustrates road conditions corresponding to present road very
It is bad, it may be possible to road ice layer thickness is thicker, wind-force corresponding to current road segment is larger, water accumulating volume corresponding to current road segment is more,
The surface evenness of current road segment is poor, caused by the current road segment more low factor of visibility, illustrates to drive a vehicle in current road segment
Degree of difficulty is larger, then needs to input warning information best friend's siphunculus platform, for arranging corresponding administrative staff to carry out traffic
Commander, with the generation to avoid traffic accident.
Further, in the alternative embodiment of method one of dynamic adjustment road speed limit of the invention, include after step S20：
The difference between the speed limit that the current speed limit and preset display screen are currently shown is detected whether more than default
Threshold value；
If the difference between the speed limit that the current speed limit and preset display screen are currently shown exceedes predetermined threshold value,
The current speed limit is shown in preset display screen.
In an alternate embodiment of the present invention, for example, the speed limit that computer receives is 69km/h, then the speed limit is detected
Whether the difference of the speed limit shown with current display screen exceedes predetermined threshold value, and (for example, threshold value is arranged to 10km/h, threshold value is set
Putting can be modified according to actual conditions, not be limited herein), if for example, the speed limit that current display screen is shown is 89km/h,
The difference for the speed limit that the speed limit of current selected is shown with current display screen has reached 20km/h, then by the speed limit of current selected
Value 69km/h renewals are shown on display screen, display screen and current road segment entrance at a distance of pre-determined distance, such as set this default away from
From for 500m.As shown in figure 3, Fig. 3 is the schematic diagram of a scenario that display screen of the present invention shows the embodiment of speed limit one.
In another optional the present embodiment is invented, if the speed limit of current selected be 69km/h, detect the speed limit and
Whether the difference for the speed limit that current display screen is shown exceedes predetermined threshold value (for example, threshold value is arranged to 10km/h, the setting of threshold value
Can be modified according to actual conditions, be not limited herein), if for example, the speed limit that current display screen is shown is 75km/h, when
The difference for the speed limit that preceding selected speed limit is shown with current display screen is 6km/h, then need not be to the current display of display screen
Speed limit be modified, speed limit 75km/h is still shown on display screen.
In the present embodiment, after current speed limit is obtained according to road condition data, current speed limit is shown with display screen
Speed limit be compared, only the difference between the speed limit that current speed limit and display screen are shown exceedes predetermined threshold value
When, just the renewal of current speed limit is shown on display screen, otherwise the speed limit of the current display of display screen is not modified, this
Sample one, avoid frequently to showing that the speed limit of screen display is modified.
