The interactive method with the zebra crossing system is integrated on a wearable device, and the device integrates various related devices and functions such as ultrasonic induction ranging, RFID (radio frequency identification), a GPS chip, voice broadcasting and the like, so that interaction with the zebra crossing system through the wearable device is realized, and a visually impaired person can sense the approximate distance of a front obstacle and the current position information; when the visually impaired personage walks on the zebra crossing of this project design, this wearable equipment can discern the radio frequency identification label that sets up at the zebra crossing edge, thereby obtains the remaining distance information of zebra crossing and detects the walking route that whether the wearer deviates the zebra crossing through decoding label information, if reach the setting value of deviating then carries out voice broadcast: "Please note: you have deviated from the normal walking path! If the deviation from the set value is not achieved, the residual distance information of the zebra crossing is broadcasted in a voice mode.
When a closer obstacle appears in the road, the wearing device can timely remind the blind people of avoiding the obstacle through voice broadcasting of the obstacle and the distance information of the obstacle. The ultrasonic transmitter is used for transmitting ultrasonic waves to the front, timing is started at the same time of transmitting time, the ultrasonic waves are transmitted in the air and return immediately when encountering an obstacle on the way, the ultrasonic receiver stops timing immediately after receiving reflected waves, and the distance between the ultrasonic receiver and the obstacle is calculated through a time difference distance measuring method. The method is utilized to design a distance measuring circuit, an input end is connected with a port of a wearable device control system, the wearable device control system executes a written program, a pulse signal with a certain frequency is output at the port, the pulse signal is amplified by a triode and drives an ultrasonic transmitting head to send out pulse ultrasonic waves with corresponding frequency; the receiving head converts the ultrasonic modulation pulse into an alternating voltage signal, and the alternating voltage signal is amplified by the operational amplifier and subjected to frequency modulation processing by other elements and then is transmitted to the wearable equipment control system for processing and calculation. The processed obstacle sensing information and distance information are transmitted to a voice module to remind the visually impaired people; when the barrier apart from wearable equipment 50cm, voice module reports: "front 50CM with obstacles"; when the barrier is apart from wearable equipment 100cm, voice module reports: "one meter ahead has an obstacle".
Through set up the radio frequency identification label in zebra crossing both sides, the radio frequency identification label has write in specific information for operations such as recognizer discernment, decoding to the operation such as information acquisition is carried out to the construction wearable equipment operating system, handles, transmits. When the visually impaired people walk on the zebra crossing, the wearable device identifies the tags beside the zebra crossing through the radio frequency identification reader, finally obtains the information of the remaining distance of the zebra crossing and the information of whether the zebra crossing deviates from the route and informs the visually impaired people through voice, so that the visually impaired people can sense the positions of the visually impaired people and can be guided to walk on the zebra crossing correctly.
The specific implementation process is as follows: the zebra crossing edge is provided with the blind brick of radio frequency identification label, installs radio frequency identification reader antenna and recognizer on the wearable equipment, and the recognizer passes through the radio frequency signal of antenna transmission certain frequency, thereby produces induced-current and obtains the energy when radio frequency identification label gets into magnetic field, sends the markedness information such as self code, distance to the recognizer. Then the recognizer collects and decodes the information, and sends the information of the orientation, the distance and the like obtained by decoding to an operating system of the wearable device for processing. Before the radio frequency identification reader reads the information of the blind brick label, three pieces of information need to be written into each label: 1. right (or left); 2. the numbers 1, 2, 3 … …; 3. distance information: 10m, 5m, 0 m. The labels are uniformly placed in combination with the actual length of the zebra crossing, and the increasing sequence of numbers and distance information in the label information is opposite: if the distance between the right side line and the zebra crossing is 1,10m, and the distance between the right side line and the zebra crossing is 2,5m, the left turn is required; otherwise, the left line needs to be turned right. If a right 1, right 2 increment and a left 5, left 4 decrement are read, the decrement should be dropped and the increment should be taken. The operating system of the wearable device processes the decoding information read by the reader, and sends the left distance information and the left-right turn information of the zebra crossing to the voice module to inform the visually impaired people; meanwhile, the reader reads information from the adjacent radio frequency identification tag and detects the signal intensity, and the distance measurement is approximately realized by detecting the signal intensity of the radio frequency identification tag; and processing different signal strengths of the electronic tag RSSI, performing distance classification on the signal strengths to obtain the strongest signal strength, namely the closest distance, comparing the strongest signal strength with the safe distance, and transmitting information to a voice module to warn the visually impaired people to deviate from the zebra crossing route if the strongest signal strength is smaller than the safe distance.
