Event-driven remote wireless coalbed methane well station abnormal scene safety monitoring method

Abstract

The invention discloses an event-driven remote wireless coalbed methane well station abnormal scene safety monitoring method, which belongs to the field of information technology. A background difference method and an improved nuclear density target detection algorithm are fused, the background difference method is firstly used for fusing a three-frame differencing algorithm to segment the image into a dynamic background area and a non dynamic background area, a nuclear density algorithm is then used for segmenting a foreground as for the dynamic background area, abnormal scenes (containing interference signals) and normal scenes are separated and processed, and thus, conflicts between algorithm complexity and real-time requirements can be well solved. When the foreground is segmented, through theoretical derivation, the scheme creatively provides a dynamic threshold calculating method. The method has the beneficial effects that the field abnormal scenes are separated from interference information such as movement of a pump and any sign of movement, and only when real abnormal scenes or events happen, field intelligent monitoring equipment gives an alarm to a monitoring center, field image information is sent, and low-cost and high-efficiency remote monitoring can be realized.

Description

technical field [0001] The invention belongs to the field of information technology, and relates to a machine vision-based algorithm for identifying abnormal scenes in coalbed gas well stations, and in particular to an effective identification method for interference scenes that affect the identification of abnormal scenes, such as the regular movement of pumps and wind and grass in coalbed gas well stations. Background technique [0002] Coalbed methane well stations are usually located in barren mountains, with rugged roads and complex terrain. The safety monitoring of gas wells has always been a major issue related to the safe production of gas wells. Regular manual inspections are usually used for safety precautions. Such as the use of video remote monitoring technology, the technically mature wired remote security monitoring, due to the high cost of laying communication lines, enterprises cannot afford it. Wireless solutions (such as using 3G network) to transmit video,...
