The invention discloses a method and equipment for guaranteeing a visually impaired person to pass through a traffic light based on an SDN, and a medium, and relates to the technical field of assisting the visually impaired person. The method comprises the following steps: sending a wireless signal to a crossroad through wireless network equipment; under the condition that the blind guiding device recognizes the wireless signal, the blind guiding device is connected through the wireless network device; an interconnection interface between the wireless network device and the corresponding controllable signal lamp is opened through the SDN controller, and the time information and the timestamp information of the corresponding controllable signal lamp are compared; under the condition that comparison is completed, the blind guiding equipment sends time information corresponding to the controllable signal lamp and sends a signal to auxiliary blind guiding equipment, and the auxiliary blind guiding equipment comprises intersection auxiliary equipment and mobile auxiliary equipment. According to the method, visual impaired people are assisted in analyzing road conditions, the influence of severe weather can be avoided, early warning is performed in advance, external personnel are informed for assistance, and traveling of the visual impaired people is jointly protected.
