Electronic protector and traffic obstacle early warning system

The utility model discloses an electronic protector and a traffic obstacle early warning system. An electronic protector is arranged on a vehicle and at a traffic barrier; through sending and receiving obstacle signals of the 433M wireless communication modules between the electronic protectors, an alarm prompt is effectively sent out when different 433M wireless communication modules enter the mutual communication range, a driver is effectively reminded to pay attention when the reaction distance is enough, and therefore collision accidents are effectively reduced. The 433M wireless communication module has transmitting and receiving functions at the same time, so that a driver is prompted to pay attention when the reaction distance is enough, the operator at a traffic barrier is prompted to pay attention, the transmission of collision accidents is further reduced, and the loss of property economy and the injury to the operator are reduced; meanwhile, the key circuit, the positioning module, the display modu
