Description

A kind of solar energy blind guiding bar system

Technical field

This utility model relates to a kind of solar energy blind guiding bar system.

Background technology

Domestic and international existing blind-guiding stick generally only has obstacle detection and voice broadcast function, and expensive.

U.S.'s product is about 300 ~ 400 dollars, Britain reaches 500 pounds, the electronics blind-guiding stick of the energy perception people face height of the up-to-date research and development of Japan, can sense the barrier that the place ahead 2m face highly locates, but it has used two ultrasonic sensing devices, the consumables cost height, the general user be difficult to bear and function more single.

Summary of the invention

The technical problems to be solved in the utility model is existing blind-guide device function singleness, with high costs.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of solar energy blind guiding bar system comprises single-chip microcomputer, ultrasonic listening module, voice module, vibration module and solar-electricity source module; The ultrasonic listening module comprises ultrasound wave transtation mission circuit and ultrasound wave receiving circuit; The outfan of single-chip microcomputer is connected with the input of ultrasound wave transtation mission circuit, voice module and vibration module respectively; The input of single-chip microcomputer connects the outfan of ultrasound wave receiving circuit; The input of described single-chip microcomputer also is connected with push-button unit; The solar-electricity source module is used to each module that work energy is provided.

This utility model is core with the single-chip microcomputer, control system is carried out the sub-module software design, adopt the microprocessor of better performances as controller, it is computing capability efficiently, fast interrupt response and disposal ability and low in power consumption have increased the reliability of blind-guiding stick; The ultrasonic listening module by the emission sound wave pulse time and receive that the difference of the time of echo calculates launch point apart from the distance of barrier, distance is surveyed accurately sensitive, voice unit can be reported the place ahead distance of obstacle to the blind person, and vibration unit is strengthened the prompting to the blind person by vibration.

For improving blind person's at night visibility, also be provided with the LED lighting module, the input of this module connects and by the push-button unit gauge tap, its power supply is provided by the solar-electricity source module.Open the LED lighting module night, can point out the pedestrian to have the blind person to pass by herein, so that the pedestrian initiatively avoids the blind person, ensured the safety of blind person's walking along the street at night.

For ease of maintenance, also be provided with display module, described display module comprises display driver circuit and 8 charactrons, and the input of described display driver circuit connects the outfan of single-chip microcomputer, and the outfan of display driver circuit connects the input of 8 charactrons.Maintenance person is by the display digit on 8 charactrons, can check whether operate as normal of each unit.

The utility model has the advantages that: simple in structure, energy-conserving and environment-protective, detection accuracy height, highly sensitive, reliable and stable, cost performance is high, simple to operate, intelligent blind-guiding device that function is more.
