Described obstacle information suggestion device comprises ultrasonic transmitter, ultrasonic receiver, controller and warning reminding device, described ultrasonic receiver, controller are electrically connected successively with the warning reminding device, ultrasonic receiver receives the echo-signal that the ultrasonic transmitter ultrasonic waves transmitted runs into the barrier reflection, via controller carries out date processing, sends alarm signal by the warning reminding device again.Because ultrasound wave is relatively sensitiveer, this method of ultrasound examination barrier of utilizing is not only convenient but also accurate, and simultaneously above-mentioned device volume is less, lighter.
Described obstacle information suggestion device also comprises range finder module, ultrasonic receiver receives the echo-signal that the ultrasonic transmitter ultrasonic waves transmitted runs into the barrier reflection, via controller carries out date processing, calculate the distance of barrier by range finder module, judge the position of barrier, send alarm signal by the warning reminding device again.Range finder module can calculate the distance of barrier, judge the position of barrier after, send alarm signal by the warning reminding device again and remind user to prepare for avoiding barrier.
Described apparatus for guiding blind main body is that the front is provided with opening and has the blind-guiding stick of cavity, described obstacle information suggestion device places in the cavity of blind-guiding stick, and the ultrasonic transmitter of obstacle information suggestion device and ultrasonic receiver place in the crutch of blind-guiding stick opening correspondence position.This set helps hyperacoustic transmitting and receiving, and the obstacle information suggestion device is placed in the blind-guiding stick, the convenient use.
Described warning reminding device is loudspeaker.
Described obstacle information suggestion device also comprises mike and the memorizer that is electrically connected with described controller.Mike and memorizer are set, and user can be stored in the bin by the different signal language of microphone records oneself with hobby according to the custom of oneself, such as according to the different mining of distance with different promptings.
Described warning reminding device is a vibration prompting device.
Described vibration prompting device is located at the upper hand contact position of blind-guiding stick.This set position helps user and feels vibrations.
Described blind-guiding stick is provided with two openings, a close bottom, and a close upper end, each has been driven corresponding ultrasonic transmitter and the ultrasonic receiver that a secondary obstacle information suggestion device is set and has put.Make the test specification of apparatus for guiding blind wider.
Described blind-guiding stick is provided with on and off switch with respect to the position of staff contact, and described on and off switch protrudes in the crutch surface.Help user and find switch, opening power.
A kind of apparatus for guiding blind described in the utility model owing to be provided with the obstacle information suggestion device on the apparatus for guiding blind main body, not only solved blind person's guide problem, and has saved spending for the blind person again.
Description of drawings

Fig. 2 is this utility model embodiment 2 block diagrams.
Fig. 3 is this utility model embodiment 3 block diagrams.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and preferred embodiment.
Embodiment 1
As shown in Figure 1, the described a kind of apparatus for guiding blind of present embodiment comprises the obstacle information suggestion device of blind-guiding stick and setting and blind-guiding stick inside and is the power supply of obstacle information suggestion device power supply.The obstacle information suggestion device comprises ultrasonic transmitter, ultrasonic receiver, controller and loudspeaker, described ultrasonic receiver, controller are electrically connected successively with loudspeaker, ultrasonic receiver receives the echo-signal that the ultrasonic transmitter ultrasonic waves transmitted runs into the barrier reflection, via controller carries out date processing, send the caution voice by loudspeaker again, remind user that barrier is arranged.Because ultrasound wave is relatively sensitiveer, this method of ultrasound examination barrier of utilizing is not only convenient but also accurate, and simultaneously above-mentioned device volume is less, lighter.Blind-guiding stick is exactly described apparatus for guiding blind main body, and loudspeaker are exactly described warning reminding device.Blind-guiding stick is provided with two openings with respect to the place ahead of user and the front of blind-guiding stick, an opening is near the bottom, another opening is near the upper end, and each has been driven corresponding ultrasonic transmitter and the ultrasonic receiver that a secondary obstacle information suggestion device is set and has put.Make the test specification of apparatus for guiding blind wider.The switch of described power supply is positioned at the position with respect to the staff contact of apparatus for guiding blind, and described on and off switch protrudes in the crutch surface.Help user and find switch, opening power.
During use, user is earlier with the opening on the hands touch blind-guiding stick, make opening towards the place ahead, opening power, ultrasonic transmitter will constantly send ultrasonic signal, when there is barrier in the place ahead, ultrasonic receiver receives the echo-signal that the ultrasonic transmitter ultrasonic waves transmitted runs into the barrier reflection, via controller carries out date processing, and sending the voice reminder user by loudspeaker again has barrier, and user just can be according to reminding the cut-through thing.
Certainly, in the obstacle information suggestion device, can also add range finder module, ultrasonic receiver receives the echo-signal that the ultrasonic transmitter ultrasonic waves transmitted runs into the barrier reflection, and via controller carries out date processing, calculate the distance of barrier by range finder module, judge the position of barrier, send alarm signal by the warning reminding device again, how far the distance of prompting barrier has, user can determine oneself action to avoid barrier and prepare by prompting.
Embodiment 2
As shown in Figure 2, the present embodiment difference from Example 1 only is that the obstacle information suggestion device of present embodiment also is provided with mike and the memorizer that is electrically connected with described controller.Mike and memorizer are set, and user can be stored in the bin by the different signal language of microphone records oneself with hobby according to the custom of oneself, such as according to the different mining of distance with different auditory tone cueses.
Embodiment 3
As shown in Figure 3, present embodiment and embodiment 1, only be that as Fig. 2 difference the warning reminding device of the obstacle information suggestion device of present embodiment is a vibrator, vibrator is exactly described vibration prompting device, and vibrator is located at the upper hand contact position of blind-guiding stick.This set position helps user and feels vibrations.User judges by the sensation vibrations whether the place ahead has barrier, finishes its cut-through thing.
