Abstract

The safety management system of the present invention includes: a driver authentication section which authenticates a driver of a transportation machine and outputs an authentication result; a health status determination section which measures blood component data of a driver authenticated by the driver authentication section, determines a health status of the driver from the blood component data, and outputs a determination result; and a motive power control section which permits or prohibits operation of the transportation machine by controlling motive power of the transportation machine based on the authentication result and the determination result.

Claims

1. A safety management system comprising:

a driver authentication section which authenticates a driver of a transportation machine and outputs an authentication result;

a health status determination section which measures blood component data of a driver authenticated by said driver authentication section, determines a health status of the driver from the blood component data, and outputs a determination result; and

a motive power control section which permits or prohibits operation of the transportation machine by controlling motive power of the transportation machine based on the authentication result and the determination result.

2. A safety management system according to claim 1, wherein said motive power control section controls starting of an engine of the transportation machine, based on the authentication result and the determination result.

3. A safety management system according to claim 1, wherein said motive power control section controls the motive power of the transportation machine according to whether or not values of each of items of the blood component data are within predetermined ranges.

4. A safety management system according to claim 3, wherein said motive power control section controls the motive power of the transportation machine according to whether or not values of each of specific items of the items of the blood component data are within predetermined ranges.

5. A safety management system according to claim 3, wherein said motive power control section controls the motive power of the transportation machine according to a number of items within the predetermined ranges of each of the items of the blood component data.

6. A safety management system according to claim 1, wherein said driver authentication section authenticates the driver based on a vein pattern obtained by irradiating infrared rays onto a body of the driver.

7. A safety management system according to claim 1, wherein said health status determination section measures the blood component data based on an absorption spectrum obtained by irradiating infrared rays onto a body of the driver.

8. A safety management system according to claim 1, wherein a vein pattern used by said driver authentication section and an absorption spectrum used by said health status determination section are detected by the same sensor section.
