Petroleum and chemical equipment leakage monitoring system based on wireless sensor network (WSN)

Abstract

The invention relates to a petroleum and chemical equipment leakage monitoring system based on wireless sensor network (WSN), comprising a monitoring centre, a wireless sensor network and a local area network (LAN), wherein the wireless sensor network is formed by the connection of a remote control terminal, a plurality of wireless sensors disposed in a monitoring area and easy to generate leakage parts and a personnel computer (PC) machine; the PC machine and the monitoring centre are both connected to the LAN. The design of the invention is reasonable; the leakage detection function to petroleum and chemical equipment is realized in a manner of combining the wireless sensor network with the monitoring centre; the system can perform warning processes to site accidents, as well as supplies a reliable basis for processing leakage accidents in time; the safe running of production is ensured and the automatic level of production management is improved.

Description

technical field [0001] The invention belongs to the field of petrochemical monitoring equipment, in particular to a WSN-based chemical equipment leakage monitoring system. Background technique [0002] Petroleum, chemical and petrochemical industry is one of the pillar industries of our country and plays a pivotal role in the development of the national economy. Most of the raw materials and auxiliary materials used in the petrochemical production process are flammable, explosive or highly (highly) toxic substances. Once leaked, they will easily form explosive mixtures that will burn and explode, causing casualties, environmental pollution, and even ecological disasters. Many petroleum and chemical companies pay more and more attention to safety production accidents and have invested a lot of money in equipment transformation and hidden danger control, such as: building fire exits, installing storage tank cooling water, strengthening fire embankments, installing flow meters,...

AI Technical Summary

Problems solved by technology

But adopt above-mentioned technical scheme to still have the following problems: (1) adopt the monitoring technology of wired monitoring equipment to be relatively backward, and monitor or alarm alarm by artificial on-duty monitoring in the monitoring center, take preventive measures by the operator, this mode is unfavorable for the accident Rapid emergency response after the occurrence, and the effect in accident early warning is even worse; (2) The technical research on the real-time acquisition of emergency information at the accident scene lags behind, and there is a lack of corresponding emergency information collection equipment; (3) Field equipment monitoring sensor data collection, fusion , the level of intelligence and automation of analysis is still very low; (4) After the accident, due to factors such as dense smoke (fog), high toxicity, and high temperature, it is difficult for personnel to approach the scene, and it is very difficult to confirm the source of the accident or the leak point. deal with great difficulty
