HUMAN ERROR PREVENTION SYSTEM

摘要

PROBLEM TO BE SOLVED: To prevent or suppress occurrence of human error such as the working mistakes by reading the bar code information out of a work instruction bar code and a result display bar code and collating these bar code information with each other via a work management computer. SOLUTION: The work information is expressed in a working sheet 1 and a work instruction bar code 2 and offered to a worker. At the same time, a bar code showing an additive is previously stuck on an additive container 4. The worker selects an additive and reads the bar codes 2 and 3 by a bar code reader 5. These reading results are collated with each other by a work management computer A. Based on the propriety of the collation result, a voice signal is transmitted through a speaker. Thus the worker can immediately know the propriety of his additive selection and then selects an additive again if the first selection is wrong. Then the worker puts the selected additive in a material carrier contained 7 by a prescribed amount and weighs the additive by a gauge 8. This weighing result is compared with the information acquired from the bar code 2 by the computer A. Then the propriety or excess/deficiency of the weighed value is displayed.
