Gas determines the specific value of visibility weight coefficient B and the wet and slippery weight coefficient C in ground.Such as: fine day corresponding visibility weight system
Number B=B1, cloudy day 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 wet and slippery weight coefficient C=C1 in rainy day 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 is the following steps are included: warning trolley determines the position of itself by GPS module, by wireless communication
Module is communicated with cloud server, obtains time and the road type of itself present position, is searched according to time and road type
Distance K is arranged in corresponding warning sign out, detects visibility by visibility meter, finds out corresponding visibility according to visibility
Weight coefficient H calculates safe distance D=K × H.
The third method is the following steps are included: warning trolley determines the position of itself by GPS module, by wireless communication
Module is communicated 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 setting distance K, finds out the corresponding wet and slippery weight coefficient C in ground 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 wet and slippery weight coefficient C=C1 in rainy day 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.
Fourth method is the following steps are included: warning trolley determines the position of itself by GPS module, by wireless communication
Module is communicated with cloud server, obtains time, road type and nearest N hours precipitation (the N 1- of itself present position
5) corresponding warning sign, is found out according to time and road type, distance K is set, found out pair according to nearest N hours precipitation
The wet and slippery weight coefficient M in the ground answered, detects visibility by visibility meter, finds out corresponding visibility according to visibility and weighs
Weight coefficient H, calculates safe distance D=K × M × H.
