SCANNING METHOD AND SYSTEM FOR A MULTIPLE LIGHT BEAM SYSTEM
摘要
<p>A method and system for scanning a multiple light beam system, such as a safety light curtain, uses a plurality of transmission signals including two or more synchronization signals for synchronizing a beam receiver module with a beam transmission module. The system has transmitter circuitry which generates the transmission signals for driving light sources of the transmission module and receiver circuitry which receives corresponding transmitted signals. The receiver circuitry generates a scanning initialization signal using an uninterrupted synchronization signal among the reception signals for synchronizing the receiver module with the transmission module and scans the receiver module in response to generation of the scanning initialization signal.</p>
