The intelligent blind road system comprises one or more electronic identification devices 10, wherein the electronic identification devices 10 are preferably buried under the ground of the blind road, and can also be on the surface of the blind road or above the ground. The detecting device 20 can be carried by the blind person, or can be arranged on a walking stick or other articles carried by the blind person.

In the present invention, the electronic identification device 10 may further include a signal transmitter for transmitting a signal with blind track information. The detecting device 20 receives the signal with the blind road information sent by the electronic identification device 10 and acquires the information therein for prompting or guiding the blind to walk.

The electronic identification means 10 may also comprise a signal reflector for reflecting a detection signal emitted by the detection means 20 for detecting the electronic identification means 10. The detection device 20 sends out a detection signal, the detection signal is transmitted to the signal reflector of the electronic identification device 10, the detection signal is reflected back through the signal reflector, and after the reflection signal is received by the detection device 20, relevant information is obtained from the reflection signal and used for prompting or guiding the blind to walk.

In this embodiment, the electronic identification device 10 includes a housing, a radio frequency module disposed within the housing, and a signal reflector and/or a signal emitter. The housing of the electronic identification device 10 is a non-metallic housing. Since the electronic identification device 10 needs to be buried underground for a long time, the housing may be made of a material that is moisture-proof, hydrochloric acid-proof, corrosion-proof, and extrusion-resistant. The signal reflector comprises a first identification antenna, when the first identification antenna receives a detection signal sent by the detection device 20, the detection signal is transmitted to the radio frequency module, the radio frequency module demodulates and modulates the detection signal and sends a reflection signal through the first identification antenna, the reflection signal is received by the detection device 20, and related information is obtained from the reflection signal and used for prompting or guiding the blind to walk. In the present invention, the probe signal is preferably an ultrasonic wave, and may be another type of probe signal.

The electronic identification means 10 can also actively transmit a signal with blind track information by means of a signal transmitter. The electronic identification device 10 may further include a memory for storing blind track information and the signal transmitter includes a second identification antenna. The radio frequency module modulates the blind track information on a carrier wave, then transmits the modulated signal through the second identification antenna, and the detection device 20 receives the signal with the blind track information transmitted by the electronic identification device 10, and obtains related information from the signal for prompting or guiding the blind to walk. In the present invention, the blind track information carried by the signal emitted by the electronic identification device 10 may be: warning information, prohibition information, instruction information, direction information, road surface condition information, construction information, route information, turn information, stop information, prohibition information, traffic light information, avoidance information, and the like.

In the present invention, the first identification antenna and the second identification antenna may be two different antennas, or may be the same antenna.

The detecting device 20 can also give different prompts or directions for different users, and is suitable for different users to walk. For example: when the blind person A and the blind person B respectively carry a detection device 20 to pass through the electronic identification device 10 at the intersection, the traffic light at the current intersection is a green light and is changed into a red light within 30 seconds, the blind person A is a young person, the walking speed is similar to that of a normal person, and the blind person B is an old person and is busy in walking speed. Then for the blind a he can walk through the crossing before the traffic light changes to red, so that the prompt or guide given by the detecting means 20 is: and continuing to move forward to pass through the intersection. For the blind b, he cannot walk through the crossing before the traffic light changes to red, so the prompt or guide given by the detecting device 20 is: the front crossing waits for passing.
