Description of the invention: [Technical field to which the invention pertains] The present invention relates to a visually impaired person, in particular to a system for integrating a zebra crossing to guide a visually impaired person through a zebra crossing. [Prior Art] Eight straight in two! i live 'for example, 'going from home to the bus stop waiting for the A car, preparing for the road on the zizi road π, etc., for the general vision of 10 15 people may be a breeze, but for the visually impaired, However, it is a matter of a lot of articles. _Friends in life ^: weak = other sensory organs to detect their relative to the environment; set the basis for judging choices when they are away. In modern cities, the degree of traffic chaos has far exceeded the scope of self-processing. Peng left on the road. The government has a guide brick to guide visually impaired friends. However, (4) it is often visible that the roads are blocked by locomotives or other sundries. In addition, according to Wan Mingmei (2_); show that the domestic guide bricks sometimes lead the visually impaired to the danger zone, although =:, guide: brick still has a positive guiding role. If you go to a bad brother without a blind brick, the visually impaired will be at a loss. At this stage, it is very rare for the visually impaired to cross the road. The traffic intersection at the 20th district (such as Taipei City) is equipped with a switch button. When the switch is converted to a green light, it can be provided, but there is no paste. U informs the visually impaired. A small number of metropolitan areas and the green light fixtures of the Qiming School are equipped with touch slaves. When the visually impaired users press the button, they will make a sound in the green light state, prompting to use 4 201002912 ^ = more roads, but _ The interest rate and the number of seconds can't be strong, and the zebra crossing/direction has guidance' and the sound will interfere with the nearby home. 10 15 According to the research of Bingjieli (1999), the number set at the intersection is:, yes, normal operation', that is, the failure rate is 70%, and the damage rate is too high, causing the visually impaired to save money for the green; There is no uniform standard for Qian Zhuchun's voice. It is easy for the visually impaired to produce confusion in judgment. The study also pointed out that when visually impaired people cross the road, they mainly listen to the sound of vehicles (67%), "people are (4) (23%). Therefore, only a small number of visually impaired people rely on the aforementioned devices to ride through. When some of the Qing people cross the intersection, they still follow the situation of the vehicle's engine material or the sound of the stop, and the situation of the vehicle at the intersection is 'inferred from the pedestrian number to determine whether to cross the road. This way actually exists. There is a problem of considerable security. On the road, 'the road 4 and some of the sidewalks are not equipped with blind obstacles. It is impossible to guide the visually impaired to the starting point of the zebra crossing. It can only be explored by visually impaired friends based on experience or road vehicle sounds. In the environment to the intersection. The domestic patent bulletin (Announcement No.: 518965) has a voice guide device for providing visually impaired friends, and a color sensor is installed on the mirror to inform the red and green recording, but it is misunderstood. (5) It is impossible to provide high reliability. Another patent bulletin (Announcement No.: 563525) provides a traffic guide device, and the electromagnetic device is installed under the guide vane. When the transferer stands at the position and the green light When the shell is up, the electromagnetic principle can be used to communicate the visually impaired person with the cane or the sole, but there is no road information, green light seconds and direction guiding function. [Invention] 5 20 201002912 The main purpose of the present invention is to provide a whole person. The state 'and guides the visually impaired to safely cross the zebra crossing.
