Embodiment 1
[0029] Embodiment 1, a kind of expressway secondary accident early warning method based on big data, realizes by following steps:
[0030] (1) Actively trigger the early warning device: When an accident occurs, if the accident vehicle personnel are not injured, the vehicle personnel will turn on the trigger switch on the control device closest to the scene to actively trigger the early warning device. The early warning light in the early warning device will flash and the early warning the horn sounded;
[0031] (2) Passive triggering of adjacent early warning devices: starting from the actively triggered early warning device, the controller numbers the early warning devices. The early warning signal, the signal change rule is that the farther away from the starting point, the slower the flashing frequency of the warning light, and the lower the sound of the warning horn. On the contrary, the faster the flashing frequency of the warning light, the louder the sound of the warnin...
Embodiment 2
[0035] Embodiment 2, a method for early warning of secondary accidents on highways based on big data, its steps are consistent with Embodiment 1, the difference is: if the personnel on the accident vehicle dies or is incapacitated or cannot operate the control device due to other reasons, Passers-by connect to the network module of the nearest early warning device through mobile devices. After receiving the trigger signal, the network module transmits it to the controller and triggers the nearest early warning device. At the same time, the monitoring center sends the trigger signal to the adjacent early warning device to realize secondary alarm. Accident warning.
Embodiment 3
[0036]Embodiment 3, a method for early warning of secondary accidents on highways based on big data, its steps are consistent with Embodiment 1, the difference is: if the personnel on the accident vehicle dies or is incapacitated or cannot operate the control device due to other reasons, At the same time, when the monitoring center finds an accident through the electronic monitoring system, the monitoring center remotely triggers the nearest early warning device through the network module to realize the second early warning.
