Under vehicle mode, the speed in the travelled train in this section of wiring region is controlled, specially：According to different grades of beam wind disaster area
Between, control makes the speed of train be down to preset section；
(1) instantaneous wind speed is 14.0-17.0m/s, then control makes the speed of train operation within 30km/h, is 1 grade of blue
Early warning；
(2) instantaneous wind speed is 17.0-20.0m/s, then control makes train running speed within 25km/h, is that 2 grades of yellow is pre-
It is alert；
(3) instantaneous wind speed is 20.0-24.0m/s, then control makes train running speed within 20km/h, is 3 grades orange pre-
It is alert；
(4) instantaneous wind speed is greater than 24.0m/s, then control makes suspension of service, is 4 grades of red early warning.
3. light rail beam wind information collection according to claim 1 and method for early warning, which is characterized in that moved described in step 3
State generates the reference threshold of beam wind calamity source, specially：
Based on aforementioned history beam wind disaster a situation arises data, beam wind strength information-beam wind calamity is obtained using clustering algorithm
The grade interval distribution of evil reference threshold；Sentenced with the beam wind strength information that beam wind information collecting device position is current
It is disconnected, determine the grade interval belonging to it；It is referred to using the beam wind disaster of the grade interval belonging to it as current beam wind intensity feelings
The reference threshold of condition judgement.
4. a kind of light rail beam wind information collection and early warning system, which is characterized in that including：It is distributed in the beam wind information of Light rail
Acquisition device, current signal/numerical signal conversion equipment, the reference threshold device, pre- for dynamic generation beam wind calamity source
Determination device, positioning device, control vehicle device, storage device and the control device of alert program starting.
5. light rail beam wind information collection according to claim 4 and early warning system, which is characterized in that the beam wind information is adopted
Acquisition means are made of beam wind air velocity transducer and beam wind wind transducer.
