System characteristics
The signal collector in the switch output type vibration optical cable alarm system is an intelligent switch output alarm device, which forms an optical cable intrusion detection alarm system with the vibration sensing optical cable and the general switch input type alarm host. The system has strong anti-interference ability and good reliability. Besides detecting intrusion in many ways, it can also shield false alarms caused by most environmental factors. The circuit part of the signal collector has taken safe and reliable lightning protection measures. In addition, an assistant software for on-site acquisition and analysis of optical cable signals is added, which can select the appropriate discrimination mode and sensitivity in special application places (when the 8-bit dip switch setting on the circuit board cannot meet the on-site situation). The collector shell is made of high-strength engineering plastic, which is light in material and has reliable sealing and waterproof performance.
principle of operation
When the optical cable sensor is affected by external vibration, some characteristics of the transmitted light in the optical cable will change. By configuring special sensing equipment and collecting and analyzing signals, the changes of light characteristics can be detected.
