METHOD FOR REDUCING METAL DETECTION SYSTEM FALSE ALARMS |
摘要 |
A system and method for reducing the occurrence of false alarms in metal detection systems and combination EAS/metal detection systems. The system includes a motion sensor mounted on or near an antenna housing, such as an EAS pedestal, at the entrance/exit of a given interrogation zone. The motion sensor detects movement or vibration of the antenna housing. The sensor transmits signals to a controller that determines if the antenna housing has moved a predetermined amount. The system includes a metal detection module that determines if metal objects are proximate the pedestal. If metal objects are detected, a metal detection alarm is enabled. However, if it is determined that the antenna housing is moving or vibrating at least a predetermined amount, the controller inhibits generation of the metal detection alarm signal. |
