Abstract

A safety management system includes a user authentication section which authenticates a user of a particular facility and outputs an authentication result, and a health status determination section which measures blood component data of a user authenticated by the user authentication section. The health status determination section determines a health status of the user from the blood component data and outputs a determination result. An entry regulating section permits or prohibits entry by the user to the particular facility based on the authentication result and the determination result.

Claims

1. A safety management system comprising:

a sensor that irradiates infrared light onto a portion of skin of a user of a particular facility, the sensor receiving the light passed through the portion of the skin of the user, the sensor acquiring, from the received light, optical information related to a vein pattern of the portion of the skin of the user and blood component data of the user including a plasma protein level and a lactic acid level;

a user authentication section including a processor that processes the optical information to acquire the vein pattern, the user authentication section authenticating the user based on the vein pattern and outputting an authentication result;

a health status determination section including a processor that processes the optical information to acquire the blood component data of the user the health status determining section determining whether values of the plasma protein level and the lactic acid level in the blood component data measured by the health status determination section are within pre-registered blood component data values indicating an appropriate health status of the user for operating equipment inside the particular facility, and the health status determination section outputting a determination result, wherein the health status determination section is configured to correct ranges of the pre-registered blood component data values based on previously acquired blood component data of the user; and

an entry regulating section which permits or prohibits entry by the user to the particular facility based on the authentication result and the determination result.

2. A safety management system according to claim 1, further comprising, in addition to or instead of said entry regulating section, an operation regulating section which permits or prohibits operation of equipment inside the particular facility based on the authentication result and the determination result.

3. A safety management system according to claim 1, wherein the blood component data of the user consists of the plasma protein level and the lactic acid level.

4. A safety management system according to claim 1, wherein the pre-registered blood component data values are set based on an age and gender of the user and individual differences.
