Abstract
The design of the vibration monitoring system is based on the hardware of vibration sensor and signal conditioning circuit, virtual instrument as a diagnosis and alarm platform, auxiliary data acquisition card and alarm equipment. When the outside intrudes into the detection range, the vibration signal is generated and collected. The alarm is realized through the linkage of security monitoring system, so the video surveillance and video recording of the detection area are completed. In addition, the system opens the illumination equipment in the detection range to compensate for the environment of the video and deter the illegal intruders. The system includes acquisition of weak vibration signal by vibration sensor,amplification and adjustment of vibration signal by CCTV. This system has high feasibility and wide coverage. It is worth popularizing in security system in the future.
