Problems solved by technology

[0005] However, in actual operation, there are two subjective factors due to the answers of the testees: 1. The testees are unwilling to be verified as being in a state of mental fatigue; Wrong answer
According to previous test experience, the measurement error is relatively large. If this method is applied to the actual mental fatigue detection, the accuracy of the measurement results cannot be guaranteed. have serious deficiencies

Embodiment 1

[0031] refer to figure 1 , a device for stroboscopically testing people's mental fatigue, including a stroboscopic light source, a display unit composed of a plurality of stroboscopic light sources, the light sources in the display unit are divided into two groups, and the luminous frequency of each group Adjustable respectively, one group is used as a test light source to emit a luminous frequency lower than the stroboscopic threshold limit of ordinary people, and randomly displays graphics, text or symbols, and the other group is used as a background light source to emit a frequency higher than ordinary people. The luminous frequency of the flicker threshold limit, the test light source and the background light source strobe at the same time;

[0032] An input circuit is provided for the subject to input the observation result after observing the stroboscopic display unit;

[0033] There is a display screen for displaying information;

[0034] The display unit, the input c...

Embodiment 2

[0048] A method for quantitatively testing people's mental fatigue with stroboscopic flickering, comprising the step of observing a stroboscopic light source by a subject, in the step, the stroboscopic light source observed by the subject is a display unit or a display array;

[0049] If the testee can distinguish the flashing graphics, characters or symbols of the test light source in the display unit or display array, then the tester will observe the display unit or display array for testing after fine-tuning the luminous frequency of the test light source;

[0050] If the subject cannot distinguish the flickering graphics, characters or symbols of the test light source, after fine-tuning the luminous frequency of the test light source, the subject observes the display unit or display array for testing until

[0051] If the subject undergoes a change from distinguishable to indistinguishable or from indistinguishable to distinguishable, then the test luminous frequency of the...

Embodiment 3

[0075] A stroboscopic method for qualitatively testing people's mental fatigue, comprising a step in which the subject observes a stroboscopic light source, and in the step, the stroboscopic light source observed by the subject is a display unit or a display array;

[0076] If the subject can distinguish the flashing graphics, text or symbols of the test light source in the display unit or display array, the subject has not yet reached the level of mental fatigue corresponding to the test frequency;

[0077] If the subject cannot distinguish the flashing graphics, characters or symbols of the test light source, the subject has exceeded the mental fatigue level corresponding to the test frequency.

[0078] If you need to improve the test accuracy, repeat the test many times.

[0079] Adopt the device of embodiment 1, carry out the mental fatigue degree of stroboscopic qualitative test people with this test method:

[0080] Application example 1:

[0081]The testee observes th...

Abstract

The invention discloses a method and a device for quantitatively or qualitatively testing mental fatigue degree of a testee by stroboflash. The quantitative test method comprises the following steps: allowing a testee to observe a stroboscopic light which is a display unit; and if the testee can identify a flashing image on the test light, increasing the frequency of the test light source and observing the display unit, or if the testee cannot identify the flashing image on the test light source, decreasing the frequency of the test light source and allowing the testee to observe the display unit again until the testee undergoes a change from being capable of identifying into being incapable of identifying or from being incapable of identifying into being capable of identifying, wherein the last test light frequency at which the testee can identify the image is the current stroboflash threshold of the testee. The method is not affected by the subjective aim of the testee and can quantitatively or qualitatively test the mental fatigue degree of the testee. The method is very workable, simple and reliable, and test result obtained by the method is accurate and high. The test device has the advantages of stable performance, simple operation, low cost, and convenience for carrying.

Description

technical field [0001] The invention relates to a method and a device for testing people's mental fatigue, in particular to a method and a device for quantitatively or qualitatively testing people's mental fatigue by stroboscopic. Background technique [0002] The determination of human mental fatigue is a difficult problem that has been faced in the work that has special requirements for human mental fatigue, such as: the detection of whether drivers of cars and trains are fatigued, the detection of mental fatigue of pilots, and the detection of certain special types of workers. Mental state testing before work and some scientific research related to mental fatigue, etc. [0003] According to the study of the threshold value of the human body according to ergonomics, it is found that people can distinguish the flickering of the light emitted by the light source with low-frequency flashes. When the frequency of low-frequency flashes increases to a certain value, people will ...
