Contact.
Safe distance D determination method can be any one in following four kinds of methods in step S2：
First method comprises the following steps：Warning dolly determines the position of itself by GPS module, passes through the first radio communication
Module communicates with cloud server, time, road type and the weather condition of itself present position is obtained, according to time and road
Type search goes out corresponding warning sign and set apart from K, finds out corresponding weight coefficient A according to weather condition, calculates safety
Apart from D=K × A.Weight coefficient A includes visibility weight coefficient B and ground wet and slippery weight coefficient C, A=B × C, according to not on the same day
Gas determines visibility weight coefficient B and the wet and slippery weight coefficient C in ground concrete numerical value.Such as：The corresponding visibility weight system of fine day
Number B=B1, cloudy corresponding visibility weight coefficient B=B2, rainy day corresponding visibility weight coefficient B=B3, the corresponding energy of snowy day
Degree of opinion weight coefficient B=B4, greasy weather corresponding visibility weight coefficient B=B5；The rainy day wet and slippery weight coefficient C=C1 in corresponding ground,
The wet and slippery weight coefficient C=C2 in the corresponding ground of snowy day, the wet and slippery weight coefficient C=C3 in the corresponding ground of other weather.
Second method comprises the following steps：Warning dolly determines the position of itself by GPS module, wireless by first
Communication module communicates with cloud server, time and the road type of itself present position is obtained, according to time and road type
Find out corresponding warning sign to set apart from K, visibility is detected by visibility meter, corresponding energy is found out according to visibility
Degree of opinion weight coefficient H, calculates safe distance D=K × H.
The third method comprises the following steps：Warning dolly determines the position of itself by GPS module, wireless by first
Communication module communicates with cloud server, obtains time, road type and the weather condition of itself present position, according to the time and
Road type finds out corresponding warning sign and set apart from K, and the corresponding wet and slippery weight coefficient in ground is found out according to weather condition
C, visibility is detected by visibility meter, and corresponding visibility weight coefficient H is found out according to visibility, calculate safety away from
From D=K × C × H.Such as：The rainy day wet and slippery weight coefficient C=C1 in corresponding ground, the wet and slippery weight coefficient C=C2 in the corresponding ground of snowy day,
The wet and slippery weight coefficient C=C3 in the corresponding ground of other weather.
4th kind of method comprises the following steps：Warning dolly determines the position of itself by GPS module, wireless by first
Communication module communicates with cloud server, obtains time, road type and the nearest N hours precipitation of itself present position（N is
1-5）, corresponding warning sign is found out according to time and road type and set apart from K, is found out according to nearest N hours precipitation
The corresponding wet and slippery weight coefficient M in ground, detects visibility by visibility meter, corresponding visibility is found out according to visibility
Weight coefficient H, calculates safe distance D=K × M × H.
