Description

Driver's electronics of refreshing oneself

Technical field

This utility model relates to electronic machine, the electronic machine of a kind of driver's of can be used for anti-fatigue-driving of more specifically saying so.

Background technology

Vehicle accident brings about great losses all can for country and individual family every year, wherein have is because driver tired driving causes greatly, a lot of people recognize the hazardness of fatigue driving, can effectively not address this problem but have a kind of electronic product easily and effectively up to now.

The utility model content

This utility model is to be the weak point avoid above-mentioned prior art to exist, provides a kind of driver the electric electronics of refreshing oneself, by the stimulation of safety pulse voltage, human body is tingled, short time is eliminated driver's feeling of fatigue, thereby allaying tiredness is driven the hidden danger of bringing, and improves traffic safety.

This utility model technical solution problem adopts following technical scheme:

The refresh oneself construction features of electronics of this utility model driver is that its circuit is formed and comprised:

One single-chip microcomputer produces pulse signal with it, and described pulse signal is exported with the safe pulse signal that is not more than 36V through shaping, amplification;

One FM circuit produces adjustable voltage with frequency modulation potentiometer W1, and described adjustable voltage is converted to digital signal through A/D and adds to the single-chip processor i/o end, adjusts the frequency of single-chip microcomputer output pulse signal with it;

One modulation circuit produces adjustable voltage with amplitude modulation potentiometer W2, adjusts the amplitude of output pulse signal through amplifying circuit with described adjustable voltage;

One booster circuit is controlled booster circuit under the effect of single-chip microcomputer generation pulse signal, the power supply low-voltage is promoted be the working power voltage of pulse amplifying circuit.

The I/O end that construction features of the present utility model also is at described single-chip microcomputer is provided with output control pause switch K2.

Compared with the prior art, the beneficial effects of the utility model are embodied in:

1, this utility model is with electric impulse signal human body to be stimulated, and human body is tingled, and the short time is eliminated driver's feeling of fatigue, thereby allaying tiredness is driven the hidden danger of bringing, and improves traffic safety.

2, this utility model is provided with the Frequency And Amplitude Modulation circuit, by adjusting the frequency and the amplitude of voltage pulse output, can be suitable for the different requirements of different user for twinge degree and sensation.The pulse that frequency is lower produces the sensation of acupuncture more clearly; And frequency when higher because the seriality that stimulates allows the people experience lasting pain; Pulse amplitude hour, human body has the sensation of slight numbness; When pulse amplitude was big, the people knew from experience the sensation that produces twinge, and the amplitude of signal is big more, and is obvious more to the effect of human body.

Description of drawings

Fig. 1 is this utility model structural representation.

Below by the specific embodiment, the utility model is described in further detail in conjunction with the accompanying drawings.

The specific embodiment

Referring to Fig. 1, the circuit structure setting in the present embodiment comprises:

One single-chip microcomputer produces pulse signal with it; Described pulse signal is exported with the safe pulse signal that is not more than 36V through shaping, amplification;

One FM circuit produces adjustable voltage with frequency modulation potentiometer W1, and described adjustable voltage is converted to digital signal through A/D and adds to the single-chip processor i/o end, adjusts the frequency of single-chip microcomputer output pulse signal with it;

One modulation circuit produces adjustable voltage with amplitude modulation potentiometer W2, adjusts the amplitude of output pulse signal through amplifying circuit with described adjustable voltage;

One booster circuit is controlled booster circuit under the effect of single-chip microcomputer generation pulse signal, the power supply low-voltage is promoted be the working power voltage of pulse amplifying circuit.

For the ease of using, can supporting signalization output electrode.

In specifically implementing, at the I/O of single-chip microcomputer end intermittently output control switch K2 is set, this structure setting can make this utility model be operated under the two states: K switch 2 is continuous duty when being disconnection; K switch 2 is the discontinuous operation state when being closed.

During use, the coat connection that signal output electrode and human body is exposed touches, such as contacting on certain position of palm, arm or shank, turn on the power switch K1, select continuously or working method intermittently by pause switch K2, obtain required stimulation mode and degree by frequency modulation and amplitude modulation and get final product.
