Problems solved by technology
Whether it is battery replacement or external charging, it is cumbersome, which is not conducive to the promotion of blind navigation smart shoes
[0003] Existing blind navigation smart shoes generally use infrared rays to measure obstacles. The measurement distance should not be too close, let alone detect obstacles that are about to touch the shoes, such as small stones, let alone long-distance obstacles. Objects, such as passing motor vehicles, etc.
[0004] The existing guide shoes have a single alarm form, without comprehensive consideration of the impact of road conditions or the environment

Embodiment Construction
[0019] refer to figure 1 , figure 2 As shown, the micro-ultrasonic and near-infrared navigation blind wearable smart shoes provided by the present invention include soles and uppers. The soles have a thermocouple power generation device, which converts the thermal energy of the feet into electrical energy for use by the power module; from the micro-ultrasonic transceiver 4 and the near The signal of infrared transmitter receiver 3 is converted into sound signal and vibration signal after being processed to remind the blind person of the situation of the obstacle ahead. The sole has a PN junction thermocouple power generation device 11, the power generation device 11 is connected to the electric energy storage 8, the electric energy storage is connected to the microprocessor 7, a miniature ultrasonic transceiver 4 is arranged in the middle of the front end of the shoe upper, and near-infrared emission devices are arranged on both sides of the front end of the shoe upper. Rece...

The invention discloses a miniature ultrasonic and near-infrared navigation wearing intelligent shoe for a blind person. The shoe comprises a shoe sole and a shoe upper. The shoe sole is provided with a power generation device. The power generation device is connected with an electric energy storage. The electric energy storage is connected with a microprocessor. A miniature ultrasonic transceiver is arranged in the middle of the most front end of the shoe upper. The two sides of the most front end of the shoe upper are provided with near infrared emission receivers. The miniature ultrasonic transceiver and the near infrared emission receivers are connected with a signal processor of the shoe sole. The microprocessor is connected with a built-in loudspeaker, a built-in vibrator, a switch, a controller, the signal processor, the near infrared emission receivers and the miniature ultrasonic transceiver. The controller determines the microprocessor to process close-range barrier signals sent by the near infrared emission receivers or remote barrier signals sent by the miniature ultrasonic transceiver, and different responses are made according to the barrier signals so as to perform navigation on the blind person.
Description
technical field [0001] The invention relates to a smart shoe worn by a blind person with micro-ultrasonic and near-infrared navigation, in particular to a smart shoe that converts obstacles and obstacle distances in front of the shoe into sound signals and vibration signals to guide the blind person. Background technique [0002] Traditional smart shoes with navigation functions for the blind are generally equipped with disposable batteries, or rechargeable batteries that need to be charged from the outside to meet the power consumption of various smart devices in the shoes. Whether it is battery replacement or external charging, it is cumbersome, which is not conducive to the promotion of blind navigation smart shoes. [0003] Existing blind navigation smart shoes generally use infrared rays to measure obstacles. The measurement distance should not be too close, let alone detect obstacles that are about to touch the shoes, such as small stones, let alone long-distance obsta...
