The specific embodiment
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Device connection diagram inside and outside the handle of blind person's radar walking stick that Fig. 1 provides for embodiment of this utility model, this blind person's radar walking stick comprises handle and cane bar, also comprises: be arranged on handle inside, measure the radar installations 1 of obstacle distance; Be arranged on handle surfaces, start the switch 2 of radar installations 1 and send the prompting apparatus 3 of information according to the measurement result of radar installations 1; Be arranged on handle inside, be the battery 4 of radar installations 1 and prompting apparatus 3 power supplies.
The blind person is in walking or by bus etc. in the daily life, can be as required the switch 2 on starting handle surface at any time, under the triggering of switch 2, radar installations 1 is launched sound wave, sound wave is reflected after running into barrier, received by radar installations 1, and then this radar installations 1 can be calculated the distance of barrier with the velometer that the time difference and the sound wave in the reception sound wave moment are propagated constantly according to the emission sound wave in air.If the distance of barrier within the specific limits, then send information to the blind person by prompting apparatus 3.
Blind person's radar walking stick that present embodiment provides is measured the distance that the place ahead cane hinders thing by the radar installations that is provided with in the handle, and is sent information to the blind person, easy to use and safety.
The inside and outside device connection diagram of the handle of blind person's radar walking stick that another embodiment of Fig. 2 this utility model provides, this blind person's radar walking stick comprises: handle, cane bar, radar installations 1, switch 2, prompting apparatus 3, battery 4; Further, radar installations 1 is made up of ultrasound probe 11 and processor 12; Ultrasound probe 11 comprises sonic wave transmitting circuit 111 and sound wave receiving circuit 112; Sonic wave transmitting circuit 111 in the ultrasound probe 11 is launched sound wave under the startup of switch 2, and receives the sound wave that barrier reflects by sound wave receiving circuit 112; Processor 12 calculates the distance of barrier according to the moment of ultrasound probe 11 emission sound waves and the moment of reception sound wave, and controls prompting apparatus 3 according to the distance of barrier and send information.
L＝340*(X2-X1/2；
Wherein, L represents the distance of barrier; The aerial spread speed of ultrasound wave is 340 meter per seconds; X2 is that sound wave receiving circuit 112 receives sound wave constantly; X1 is the 111 emission sound waves moment of sonic wave transmitting circuit; The unit of X2-X1 institute value is second.
Blind person's radar walking stick that present embodiment provides, its radar installations 1 can reach 0.35～4 meter measuring range, calculating when single-chip microcomputer after the distance of barrier, can when entering in the certain limit, distance send control instruction to prompting apparatus 3, control prompting apparatus 3 sends information to the blind person, prompting apparatus 3 in the present embodiment adopts electromagnetic shaker, send the vibrations information by this electromagnetic shaker to the blind person, in addition, prompting apparatus 3 can also adopt such as other devices such as buzzer or voice prompting devices and send information to the blind person.
