Description

DETAILED DESCRIPTION OF THE INVENTION The present invention detects changes in skin resistance between parts of the human body, analyzes the detection results, and compares them with a preset situation pattern. The present invention relates to a mental status determining device that can reliably grasp a person's mental status and issue an alarm if the mental status of a person is unstable.

The human mind and emotions often become unstable at times, and these phenomena are likely to occur due to, for example, excitement due to mental shock, overwork due to mental labor, temporary lack of sleep, etc. When this mental or emotional state is unstable, it is easy to make mistakes at work, cause traffic accidents, and cause serious injuries, and such unstable situations should be constantly monitored through constant or periodic measurements. It should be possible to prevent major accidents from occurring by monitoring and detecting dangerous mental states and emotional instability.

For this reason, methods have been used to measure a person's mental and emotional state, and one method is called galvanic skin response (CGSR), which involves placing electrodes on the skin of the human body at intervals. The situation of the person to be measured can be determined by the change in resistance value between both electrodes. This is because skin resistance is not simply due to sweat gland activity, but the state of sweating in the palms changes due to physiological changes caused by emotional tension, and the amount of sweating can be used to determine mental and emotional stability or I-i' tension. You will be able to do so. Conventionally, this change in skin resistance is amplified in an analog manner and expressed linearly on a recording line using a pen, etc., and the change in skin resistance expressed in an analog manner is visually interpreted.
A method has been adopted in which the mental and emotional state of the person being measured is analyzed; however, this method involves large individual variations in the person being measured due to the analog expression, and analysis requires skill. It had its flaws and was not common.

In view of the above-mentioned drawbacks, the present invention digitally processes skin resistance changes and compares them with preset emotional patterns to extremely easily measure a person's mental and emotional state, and to provides a mental status determination device that can generate an alarm.

Next, the operation of this embodiment will be explained.

When trying to measure a person's mental and emotional state, the first
As shown in the figure, the measurement begins by placing the cap 7.8 on the finger of the person to be measured and turning on the power switch 3. When a preset emotional pattern occurs, the speaker 2 issues an alarm. It is possible to inform the subject that the subject is emotionally unstable and to make efforts to stabilize the subject.

In this measurement, the electrical resistance between the two fingers is detected between the caps 7 and 8, and this resistance change is transmitted from the battery 21 as a current change to the resistance change detection circuit 22.
The resistance change detection circuit 22 converts the voltage into an analog change and transmits it to the amplifier circuit 23. The amplifier circuit 23 amplifies this analog signal, transmits it to the AD conversion circuit 24, converts it into a digital signal, transmits it to the buffer register 25, temporarily stores it, and
Sampling is performed within the D conversion circuit 24 at a predetermined frequency. When the digital signal stored in the buffer register 25 is input for one cycle and is completed, the digital signal is transferred to the spin register 27 via the multiplexer 26 and is also transmitted to the DA conversion circuit 28 at the same time. This transfer is performed earlier than the next cycle input to the buffer register 25, and the input analog signal is continuously converted into a digital signal and sequentially transferred to the buffer register 25.
5 is stored. One period of the digital signal transferred to the spin register 27 is spun through the multiplexer 26 and simultaneously converted back into an analog signal by the next DA conversion circuit 28, but this spinning is performed multiple times. The input analog signal for one period is converted into multiple types of waveforms, and each analog waveform passes through a filter 29 to extract only the signal of a specific wavelength.The averaging section logic circuit 30 averages the multiple types of analog waveforms. Let me A
The signal is output to the D conversion circuit 31, and the AD conversion circuit 31 converts the averaged signal again into a digital signal and stores it in the buffer 32. The skin resistance change signal thus input is subjected to spectrum analysis and transmitted to the next DP matching section 13. In the correlation function calculation circuit 33, the autocorrelation function of the skin resistance change, which is the analysis signal from the buffer 32, is calculated every short unit time and is transmitted to the similarity calculation circuit 34.
The similarity calculation circuit 34 uses the memorized GSR pattern (skin resistance change from normal to unstable is divided into multiple patterns) and the calculated autocorrelation function to calculate the 81 degrees of the stored GSR pattern according to a predetermined formula. calculate. Then, the fl-calculated degree of similarity is transmitted to the matching unit 35, and the matching unit 35 extracts mental situation patterns that are close to the degree of similarity from the situation pattern memory 38 and compares them, and determines whether the situations are most similar or not. This is performed by the judgment circuit 39, and if the state is unstable (the degree of instability is set in advance), a signal is transmitted to the drive circuit 40, and the drive circuit 40 makes the speaker 2 sound to notify the person being measured. inform.

Furthermore, when measurement signals I/'i are successively inputted to the similarity buffer 36I/'i, the signal processing buffer 36I/'i is temporarily stalled to effectively perform signal processing.

Since the present invention is configured as described above, it is extremely easy to determine the mental and emotional state of the person to be measured based on changes in the human skin resistance.
In addition, it can be accurately determined and the state of instability and tension can be accurately known, so accidents can be prevented and mental burden can be reduced.
