The early warning device of claim 4, wherein, The controller comprises: a main control board connected with the vehicle identification device and the radar, for generating a control signal when the pre-warning trigger information and / or the feature information is received; the control signal is also used for controlling a state parameter of the warning indicator for generating the warning information, wherein the state parameter comprises intensity and / or frequency.

6. The early warning device of claim 5, wherein, The warning indicator comprises: a display connected with the main control board, for displaying visual warning information for prompting the vehicle entering the right-turn lane or the secondary lane when the control signal is received; and / or a horn connected with the main control board, for emitting audible warning information for prompting the vehicle entering the right-turn lane or the secondary lane when the control signal is received; a red-blue warning light connected with the main control board, for emitting visual warning information for prompting the vehicle entering the right-turn lane or the secondary lane when the control signal is received.

7. The early warning device of claim 6, wherein, The application further comprises: a noise detector connected with the main control board, for detecting noise intensity of the target area and generating a noise intensity signal; the main control board is further used for controlling the volume of the horn to change correspondingly when the noise intensity signal is received.

8. The early warning device according to any one of claims 1 to 7, characterized in that The application further comprises: a 4G module in communication connection with the controller and a management system, for transmitting the warning information and running state information of the controller to the management system.

9. The early warning device according to any one of claims 1 to 7, characterized in that The application further comprises: a battery connected with at least one of the controller, the detector, the identification device and the warning indicator, for providing working power; a solar photovoltaic assembly connected with the battery, for photovoltaic power generation and providing to the battery.

10. The early warning device of claim 9, wherein, The application further comprises: a stand column, the bottom of which is fixed on a support part; a fixed base assembly fixed at one end of the stand column away from the support part, for fixing and supporting the warning indicator and the controller; a support fixed at the bottom end of the fixed base assembly away from the stand column, for fixing and supporting the detector and the identification device. A photovoltaic frame is fixed at the bottom end of the bracket on the side away from the column, used to fix and support the solar photovoltaic module.
