Description of drawings

Accompanying drawing is used to provide further understanding of the present utility model, and constitutes the part of description, is used from explanation this utility model with embodiment one of the present utility model, does not constitute restriction of the present utility model.In the accompanying drawings:

Fig. 1 is the built-in electrical block diagram of intelligent blind walking stick that this utility model provides;

Fig. 2 is the external structure sketch map of the intelligent blind walking stick that provides of this utility model.

The specific embodiment

Below in conjunction with accompanying drawing the intelligent blind walking stick that this utility model provides is described.

Shown in Fig. 1 and Fig. 2 are common, the structural representation of the intelligent blind walking stick that provides for this utility model, comprise handle 7 and vertical rod 8, establish a cavity in handle 7 inside, control circuit board 11 is installed in the cavity, wherein, control circuit board 11 comprises: single-chip microcomputer 1, be used for sending the gsm communication module 2 that the GPS processing module 3 of bland person walking stick current location information, bland person walking stick current location information that GPS processing module 3 is obtained outwards send to single-chip microcomputer 1.Wherein, the GPS processing module can comprise: GPS OEM plate, a RS-232 and Transistor-Transistor Logic level modular converter, and GPS OEM plate is connected with single-chip microcomputer with the Transistor-Transistor Logic level modular converter by RS-232; The gsm communication module can comprise: gsm module, the 2nd RS-232 and Transistor-Transistor Logic level modular converter, gsm module is connected with single-chip microcomputer with the Transistor-Transistor Logic level modular converter by the 2nd RS-232.And in actual applications, the single-chip microcomputer model can be the MSP430 single-chip microcomputer.

Work process to control circuit board 1 is introduced below:

Step 101:GPS processing module 3 receives the satellite-signal that indicates the blind person position by receptor, and this satellite-signal is decoded into latitude and longitude information, then this latitude and longitude information is sent to single-chip microcomputer 1;

Step 102: the latitude and longitude information from GPS processing module 3 that 1 pair of single-chip microcomputer receives is handled, and is translated into the GSM messaging format, is sent to gsm communication module 2 then;

Step 103:GSM communication module 2 at first reads the tutorial phone number of the blind person who prestores in the single-chip microcomputer 1, and what will receive then sends to corresponding guardian from blind person's positional information of single-chip microcomputer 1 with the form of note.

In this step, can preset sending frequency, for example: 30min/ time, then gsm communication module 2 sends blind person's positional information according to preset sending frequency to blind person guardian.

As seen, after the GPS processing module sends to single-chip microcomputer with the blind person's positional information that obtains, after single-chip microcomputer is handled this blind person's positional information, send to the guardian by the gsm communication module with the form of note, thereby make things convenient for the guardian in time to monitor blind person's track route, understand the position at blind person place at any time.

In addition, the intelligent blind walking stick that provides of this utility model also has the go forward side by side function of lang sound prompting of measurement road obstacle distance.Concrete, this intelligent blind walking stick vertical rod 8 is provided with ultrasonic sensor and places window 9, in ultrasonic sensor is placed window 9 ultrasonic sensor 4 that is used to detect the road barricade thing is installed, and ultrasonic sensor 4 is electrically connected with single-chip microcomputer 1.And, single-chip microcomputer 1 also is connected with the speech chip 5 that is used for voice suggestion road barricade thing, and this speech chip 5 is connected with speaker and earphone interface respectively, wherein, speaker is installed in the speaker sound releasing hole 10, and speaker sound releasing hole 10 is arranged on the joint of handle 7 and vertical rod 8; And earphone interface 12 built-in being installed in the vertical rod 8.Wherein, the model of speech chip can be speech chip YYH402.

On specific implementation, ultrasonic sensor 4 comprises dispensing device and receiving system, when dispensing device sends ultrasound wave forward, single-chip microcomputer picks up counting, just reflect when this ultrasound wave is met barrier, form echo, single-chip microcomputer stopped timing when receiving system received this echo.By single-chip microcomputer this interval is carried out computing, just can calculate the distance of obstacle distance bland person walking stick.When meeting the predeterminable range scope, the obstacle distance that is calculated then carries out voice suggestion by speech chip.For example, if in the dead ahead effect, then can be arranged on scope is when having barrier in 2 meters, then to carry out voice suggestion; If (utilize action of gravity to remain the range finding angle and be about 60 degree) effect in the front lower place, when the scope that then can be arranged on surpasses 1.5 meters, then carry out voice suggestion.And this voice prompt can be broadcasted by speaker, makes things convenient for the blind person to hear.In addition, the blind person also can receive earphone on the earphone interface, thereby by earphone receiving barrier voice prompt.

In addition, the intelligent blind walking stick that this utility model provides also is built-in with power module 6, is used for respectively to single-chip microcomputer 1, GPS processing module 3, gsm communication module 2, ultrasonic sensor 4, speech chip 5 power supplies.

In sum, by the intelligent blind walking stick that uses this utility model to provide, both can pass through the automatic measurement road obstacle distance of ultrasonic sensor, and when reaching preset range, carry out voice suggestion, not only do not need the blind person frequent beat ground, alleviated blind person's the burden of walking, and, this kind device also has the obstacle detection distance and effective advantage, and, make things convenient for the blind person in time to understand traffic information by voice suggestion.Therefore, this device provides a great convenience for blind person's trip.

In addition,, realized blind person's current location is in time sent to the guardian with the form of note, thereby made things convenient for the guardian in time to monitor blind person's track route, understood the position at blind person place at any time by GPS processing module and gsm communication module.

It should be noted that at last: the above only is preferred implementation of the present utility model, be not limited to this utility model, although this utility model is had been described in detail with reference to aforementioned embodiments, for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned embodiments is put down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
