Dsign a residential monitoring distributed optical fiber test system, mainly includes: a light source drive and protection circuit, photoelectric detector circuit and the signal conditioning circuit. Design a set based on DSP technology of remote monitoring system for oil well, using the DSP technology of fiber optic sensor collects vibration signal of the analog to digital conversion, digital filtering, analysis and processing, and the area around the judging result through serial circuit are sent to the district monitoring center. By using the virtual instrument technology to design a set of monitoring center software system, pleted the monitoring center on the esta
