Wherein, the detection device is an infrared sensor or an ultrasonic detector, or a combination of the two; the ultrasonic sensor includes an ultrasonic transmitter and an ultrasonic receiver.

The alarm device is a vibrator or a speaker, or a combination of both. the

The handle is also provided with an earphone interface, and the earphone interface is connected with the control device.

Both the earphone jack and the loudspeaker are electrically connected to the control device through the WT588D voice processing circuit.

The control device is preferably an AT89C2051 single-chip microcomputer.

The handle is also provided with a lighting source and a lighting switch, and the lighting source is controlled by the lighting switch and powered by a power supply. the

The utility model has the following characteristics:

1. The smart crutches of the present invention can detect surrounding people and obstacles, and inform the person on crutches whether the objects in front are people or other obstacles through voice broadcast and vibration prompts.

2. When using in a dark environment, turn on the lighting source to obtain a better lighting effect, which is convenient for night travel. It also has a warning function for the elderly or blind people with poor eyesight, reminding people around them of their own existence and avoiding collisions.

3. The utility model is simple in structure and easy to use.

Description of drawings

Fig. 1 is the structural representation of the utility model multifunctional crutch.

In the figure: 1-handle, 2-body, 3-illumination light source, 4-power supply, 5-light switch, 6-alarm device, 7-detection device, 8-control device.

Detailed ways

The utility model will be further described in detail below in conjunction with the drawings and embodiments, but the drawings and embodiments are not limitations to the technical solution of the utility model.

As shown in Figure 1, the smart crutches that can detect people and obstacles include a handle 1 and a stick body 2, the handle 1 is provided with a control device 8 and an alarm device 6, and the handle 2 is provided with a detection The device 7 and the power supply 4; the alarm device 6 is electrically connected to the detection device 7 through the control device 8, and the power supply 4 supplies power to the alarm device 6, the control device 8 and the detection device 7 respectively. Wherein, the detection device 7 is an infrared sensor or an ultrasonic sensor, or a combination of the two; the ultrasonic detector includes an ultrasonic transmitter and an ultrasonic receiver.

The alarm device 6 is a vibrator or a speaker, or a combination of the two. the

Further, the handle 1 may also be provided with an earphone jack, and the earphone jack is connected with the control device 8 . Both the earphone jack and the loudspeaker are connected to the control device 8 through the WT588D voice processing circuit. The control device 8 adopts AT89C2051 single-chip microcomputer as the control core, the infrared sensor, the ultrasonic sensor and the vibrator are all connected with the control device 8, and the speaker is connected with the control device 8 through the WT588D voice processing circuit.

The handle 1 is also provided with an illuminating light source 3 and an illuminating switch 5 , and the illuminating light source 3 is powered by the power supply 4 through the illuminating switch 5 . the

The working process of the utility model: when using the crutch, the infrared sensor and the ultrasonic sensor start to detect the road surface information, and send the information obtained by the detection to the AT89C2051 single-chip microcomputer in the control device, and the AT89C2051 single-chip microcomputer judges the detection information, and then controls the The information is sent to the vibrator or to the speaker through the WT588D voice processing circuit; the vibrator vibrates or the speaker plays a prompt voice to prompt the user for road information.

Both the vibrator and the loudspeaker in the above embodiments are used to remind the user according to the detection information, and can be used in combination or alone, for example, only the vibrator or the loudspeaker is used.

Alternatively, an earphone interface is set separately, and the earphone interface is connected with the control device through the WT588D voice processing circuit, and the prompt information is received through the earphone connected to the earphone interface.

In the above embodiments, both the infrared sensor and the ultrasonic sensor are used to detect road surface information, and they can be used in combination or alone, for example, only the infrared sensor or the ultrasonic sensor is used.

The infrared sensor in the above embodiment uses a pyroelectric human body infrared sensor to detect human body information, and an ultrasonic sensor to detect obstacle information. Use the AT89C2051 single-chip microcomputer to judge the human body or obstacle information, and control the speaker to play different prompt voices.

When used at night, the lighting source can be turned on when needed, which can play a lighting role for people with good eyesight; it has a warning effect for the elderly or blind people with poor eyesight, reminding people around them of their own existence and avoiding collisions.
