GUIDING DEVICE OF MOVING BODY

Japanese Patent JPS5938809

A

PURPOSE:To make the maintenance of labellings unnecessary and to prolong the life of them, by using radioactive nuclides as labellings and discriminating them to guide the running direction. CONSTITUTION:Labellings consisting of radioactive nuclides such as 60Co and 54Mn are laid on the running path of a moving body. These labellings are detected by a detector 3 mounted on the moving body, and a running and steering control circuit 18 is driven to guide the moving body. Right-turning, left-turning, and straight-going are distinguished from one another by these labellings in accordance with classifications of radioactive nuclides. The detector 3 is constituted by storing an NaI sensor 9 and a radiation-electric converter 10 in a lead shielding body 8, and a detected radiation intensity is amplified by an amplifier 12 and is discriminated by discriminators 13a-13c and is measured by scalers 14a-14c. This result passes through an operator 15, and the direction of left-turning, right-turning, or straight-going is discriminated in accordance with the promissory condition of each labelling by a labelling discriminator 16.
