Referring to fig. 2, in one embodiment, the vibration motor 6 is disposed at the junction of the support rod 11 and the bending portion 12.
In this embodiment, the vibration motor 6 is provided at a moderate distance from the hand of the person holding the interactive smart cane, i.e., it does not cause too close proximity to the hand to make the hand of the person holding the blind fighter uncomfortable, or too far proximity to the hand to make the hand of the person holding the cane feel no vibration.
Referring to fig. 2, in an embodiment, the interactive intelligent cane further includes: and the power switch 8 is used for controlling all the electric devices.
All the electric devices are turned off when the interactive intelligent tactile stick is not used, so that the waste of electric energy stored by the tactile stick can be reduced.
Referring to fig. 2, in one embodiment, the tag reader 1 is a radio frequency identification reader, and the tag of the blind brick on the zebra crossing is a radio frequency tag.
When the blind person walks on the zebra crossing, the radio frequency identification reader emits a radio frequency signal with a certain frequency, and when the radio frequency tag enters a magnetic field, an induced current is generated to obtain energy, and the marking information such as self codes, distance and the like is sent to the radio frequency identification reader.
The radio frequency identification reader collects and decodes information on the radio frequency tag, and sends information such as the azimuth and the distance obtained by decoding to the raspberry group for processing. Three pieces of information need to be written to each tag: 1. right (or left); 2. the numbers 1, 2, 3 … …; 3. distance information: 10m, 5m, 0 m. The radio frequency tag is uniformly placed in combination with the actual length of the zebra crossing, and the increasing sequence of the numbers in the tag information and the distance information is opposite: such as right 1.10m and right 2.5 m. If the read label information is 1.10m on the right and is increased by 2.5m on the right, the label information is a right sideline and a left turn is needed after passing the zebra crossing; 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.
After the raspberry group processes the decoding information read by the radio frequency identification reader, the left distance information and the left-right turning information of the zebra crossing are sent out by a buzzer or a loudspeaker to make different frequencies or/and strong and weak sounds to inform a person holding the blind stick; meanwhile, the reader reads information from the adjacent radio frequency tags and detects the signal intensity, and the distance measurement is realized approximately by detecting the signal intensity of the radio frequency tags; and processing different signal strengths of the radio frequency tags, 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 a person holding the blind stick to deviate from the intelligent zebra crossing path if the strongest signal strength is smaller than the safe distance.
The invention provides an interactive intelligent blind stick, which has the following principle: the distance and the position of the support rod 11 from the current blind brick to the next blind brick are reported through the voice broadcasting module 5, so that a person holding the blind cane can know the distance and the position from the current blind brick to the next blind brick on a zebra crossing, and the person holding the blind cane is effectively guided, and the person holding the blind cane smoothly passes through a traffic light intersection.
A second aspect of the present application provides a zebra crossing comprising: a zebra crossing body; blind bricks arranged at two sides of the zebra crossing body; the blind brick information processing device comprises a label arranged on a blind brick, wherein the label is attached with blind brick information, the blind brick information attached to different blind bricks is different, and the blind brick information comprises blind brick numbers and blind brick positions.
In one embodiment, the tag is a radio frequency tag; zebra crossing still includes: the radio frequency warning lamps are arranged on two sides of the zebra crossing body and used for sensing the lighting state or changing the lighting state after the interactive intelligent blind stick is sensed.
The radio frequency warning lamp can sense the lighting state or change the lighting state after the interactive intelligent blind stick, so that a prompt is given to a vehicle and a driver who will pass through the zebra crossing, and the potential safety hazard of a person holding the interactive intelligent blind stick when the person passes through the zebra crossing is reduced.
The working principle of the zebra crossing provided by the invention is as follows: through setting up blind brick in zebra crossing body both sides to set up the label on blind brick, can make the people of handheld blind cane read the blind brick information on the label, thereby guide the people of handheld blind cane effectively, make the people of handheld blind cane smoothly pass through the traffic lights crossing.
