BUSINESS RISK ASSESSMENT SYSTEM

摘要

The work risk determination system according to an embodiment of the present invention is provided at the bottom of the contact portion, the fingerprint recognition unit for determining the user by providing a contact for fingerprint recognition, and whether the fingerprint is in contact with the stored fingerprint, Heart rate recognition unit for sensing the heart rate from the finger in contact with the contact portion, is provided at the bottom of the contact portion, and emits light of different wavelengths through a plurality of LED sensors to measure the light absorption, by the light absorption Oxygen saturation recognition unit for calculating the oxygen saturation degree using the ratio of the obtained pulsating component, is provided on one side of the contact portion, alcohol recognition unit for measuring the blood alcohol concentration through the user's breath and the heart rate recognition unit, oxygen saturation recognition unit and The safety recognition unit may determine a user's work risk based on the value measured by the alcohol recognition unit. According to one aspect of the present invention, the heart rate recognition unit measures the pulse rate per minute, if the pulse rate per minute 60 or more times 100 times or less normal pulse rate, the pulse rate per minute 55 or more times less than 60 times and 100 times or more than 110 times If the first pulse rate, the pulse rate per minute 50 times less than 55 times and 110 times more than 120 times less than the second pulse rate, the pulse rate per minute is defined as less than 50 times and more than 120 third pulse rate, the oxygen saturation recognition unit, Measured by the percentage (%) occupied by hemoglobin saturated with oxygen in all hemoglobin, the ratio is 95% or more the normal ratio, the ratio is 90% or more and less than 95%, the first ratio, the ratio is 75% or more 90 Less than% is defined as a second ratio, and if the ratio is less than 75%, the third ratio. The alcohol recognition unit measures blood alcohol concentration (%), and if the concentration is less than 0.03%, the normal concentration and the concentration is 0.03. % More than If it is less than 0.05%, the first concentration, if the concentration is 0.05% or more and less than 0.10%, the second concentration, if the concentration is greater than 0.10% defined as a third concentration, the safety determination unit, the normal pulse rate, normal ratio, normal Recognize the concentration as '0', recognize the first pulse rate, the first ratio, the first concentration as '1', recognize the second pulse rate, the second ratio, the second concentration as '2', the third pulse rate Recognizes the third ratio, the third concentration as '3', and if the sum of the values measured by the heart rate recognition unit, the oxygen saturation recognition unit and the alcohol recognition unit is '0', determines the work risk as 0 step. If the sum of the values is more than '1' and less than '3', the work risk is judged as one step.If the sum of the numbers is more than '4' and less than '6', the work risk is judged as two stages. '7' or more may be characterized by determining the work risk in three stages.
