<p>PURPOSE:To monitor directly a moving of individual stored goods or a non-moving thereof, and to improve a reliability of a monitoring system by judging positions of the stored goods based on received optical signals of optical axis units provided at both ends of each row and each column so as to face one another. CONSTITUTION:In a storage area 1 m by n storage pits 2 are arranged in a shape of m rows by n columns matrix and storage containers are housed in the pits 2. At both ends of individual m rows by n columns, optical axis units 10 are provided so as to face one another. The optical axis unit 10 outputs a light being sent through an optical fiber, through a lens, and receives and reflects the light by a concave mirror and a reflecting mirror to transfer the light to outside by the optical fiber. Also, the optical axis unit 10 is adjusted in its optical axis by a driving source unit remotely and bi-directionally operated in a vertical and horizontal directions. An input light and an output light of the optical axis unit 10 are received by a sub-master unit 20 or a slave unit 30, and a movement of the container is judged by a shut-off time of the optical axis caused by the movement of the storage container and finally sealing/monitoring informations are given to a monitoring staff through a personal computer.</p> |
