Abstract
The utility model discloses a simple human body fatigue detection device, comprising a unijunction transistor VU, wherein the e end of the unijunction transistor VU is connected with a variable resistor RP and a capacitor C in parallel, the b2 end of the unijunction transistor VU is connected with a resistor R1, the b1 end of the unijunction transistor VU is connected with a resistor R2 and an LED (light emitting diode) VL in parallel, and the resistor R2 and the LED VL are further connected with a power supply GB and a switch S. The simple human body fatigue detection device disclosed by the utility model has a simple structure, is reasonable in design, can test the fatigue degree of the human body by a simple detection method, and is simple, convenient and practical.
Description
Technical field
This utility model relates to a kind of simple human fatigue detection device.
Background technology
Along with the fast pace developing steps in city, the pressure that working clans go to work is also increasing, and fatigue strength is corresponding increase also, but too much weariness working can work the mischief to the health of human body.
Utility model content
Utility model object: the purpose of this utility model is in order to solve deficiency of the prior art, provides a kind of simple human fatigue detection device simple in structure, easy to use.
Technical scheme: a kind of simple human fatigue detection device described in the utility model, comprise unijunction transistor VU, the e end of described unijunction transistor VU is connected in parallel to variable resistance RP and capacitor C, the b2 end of described unijunction transistor VU is connected with resistance R 1, the b1 end of described unijunction transistor VU is connected in parallel to resistance R 2 and light emitting diode VL, and described resistance R 2 and light emitting diode VL are also connected with power supply GB and switch S.
Beneficial effect: this utility model is simple in structure, reasonable in design, fatigue strength that can testing human by simple detection method, simple and convenient practical again.
Brief description of the drawings
Fig. 1 is circuit theory diagrams of the present utility model.
Detailed description of the invention
A kind of simple human fatigue detection device as shown in Figure 1, comprise unijunction transistor VU, the e end of described unijunction transistor VU is connected in parallel to variable resistance RP and capacitor C, the b2 end of described unijunction transistor VU is connected with resistance R 1, the b1 end of described unijunction transistor VU is connected in parallel to resistance R 2 and light emitting diode VL, and described resistance R 2 and light emitting diode VL are also connected with power supply GB and switch S.
This device is the adjustable intrasonic relaxor of frequency of the composition taking unijunction transistor VU as core, the direct driven for emitting lights diode of the oscillator signal VL that unijunction transistor VU exports produces synchronization flash, whether tired comes selftest health, especially glasses by Observation Flash.
The light glimmering by certain frequency sending for light emitting diode VL, untired people can find out that light is in flicker exactly, and tired people is because the retentivity time of eye extends, and makes to find out that light is in flicker.
