The invention discloses a dual-mode communication 4G street lamp controller, which belongs to the field of controllers and comprises an AC-DC unit, a wave trap, a main control chip, a DC-AC unit, a filter, a monitoring module, a Bluetooth mesh module and a 4G module, the wire inlet end of the AC-DC unit is connected with an external power grid and is used for converting alternating current of the power grid into direct current; the wave trap is used for filtering 50hz power frequency interference of the AC-DC unit in a process of converting alternating current into direct current; the main control chip is used for carrying out edge calculation according to the traffic flow data in combination with Bluetooth mesh networking, constructing a wavelet neural network traffic flow prediction model, and achieving the intelligent prediction of the traffic flow through a wavelet neural network, thereby dynamically adjusting the on-off and brightness of street lamps in a certain region. And finally, an electric signal o
