Title:
MULTIPLE-OPTICAL-AXIS PHOTOELECTRIC SENSOR, AND SAFETY MANAGEMENT SYSTEM USING SAME
Document Type and Number:
WIPO Patent Application WO/2011/024920
Kind Code:
A1
Abstract:
Disclosed is a safety management system wherein two multiple-optical-axis photoelectric sensors (100, 200) are arranged along a path (L) via which work (W) is conveyed to a dangerous region. The downstream sensor (100) is used as a safety management sensor and the upstream sensor (200) is used as a muting sensor. The disclosed safety management system is provided with: a detection-pattern accumulation means that, at least while the muting sensor (200) has an optical axis that is blocked, accumulates detection-pattern information that represents patterns of light incidence/blockage for the optical axes of said sensor (200); and a control means. The control means determines whether or not changes in the accumulated detection-pattern information are consistent with changes in patterns of light incidence/blockage for the optical axes of the safety management sensor (100) while said sensor (100) has an optical axis that is blocked. If it is determined that the two sets of changes are consistent, the control means turns output from the safety management sensor (100) on, and if it is determined that the two sets of outputs are not consistent, the control means turns output from the safety management sensor (100) off.
