Abstract

The invention provides a leakage monitoring and positioning early-warning system in petrochemical industry and an establishment method thereof, relating to a device for prevention, inspection and position determination of gas leakage. The system comprises a host computer system, a central node, a routing node and a terminal node, wherein the software part in the host computer system comprises a geographic information system and a virtual reality control system; all the nodes are wireless network nodes comprising a ZigBee wireless module, a sensor module and a power supply module; and the ZigBee wireless module adopts a ZigBee wireless transport protocol, the sensor module carries a small leakage gas-sensitive transducer, and the power supply module is composed of a direct current cell of 3.6 V and a voltage conversion circuit. The invention achieves the synchronization of environment parameters of all monitoring points, early-warning information of potential accidents and correct positioning information of dangerous sources when an accident occurs in a monitoring center and the whole site, and the invention solves the problems that sudden leakage events can not be monitored and early-warned in time and the site information can not be acquired and transmitted in time in the prior art.

Description

technical field [0001] The technical solution of the invention relates to a device for preventing, checking and determining the location of gas leakage, specifically a leakage monitoring and positioning early warning system in the petrochemical industry and its establishment method. Background technique [0002] Domestic chemical companies are paying more and more attention to production safety accidents. Large chemical companies such as PetroChina and Sinopec have invested a lot of money in equipment renovation and hidden danger management. Over the past ten years, Sinopec has invested 8.47 billion yuan in this area, of which a total of 3.24 billion yuan was invested in the three years from 2001 to 2003. In order to completely eliminate hidden dangers, some petrochemical enterprises have spent decades, invested huge sums of money, and adopted preventive measures such as building fire escapes, installing storage tank cooling water, strengthening fire embankments, installing ...
