Go out corresponding warning sign to set apart from K, visibility is detected by visibility meter, corresponding visibility is found out according to visibility
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, passes through 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, and the corresponding wet and slippery weight coefficient C in ground is found out according to weather condition, leads to
Cross visibility meter and detect visibility, corresponding visibility weight coefficient H is found out according to visibility, calculate safe distance 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, other
The wet and slippery weight coefficient C=C3 in the corresponding ground of weather.
4th kind of method comprises the following steps：Warning dolly determines the position of itself by GPS module, passes through radio 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 pair according to nearest N hours precipitation
