Centralized monitoring system and method for gas alarm apparatus of iron works

Abstract

The invention discloses a centralized monitoring system and method for a gas alarm apparatus of iron works. For a gas alarm apparatus without a communication interface and 4-20mA standard signal output, a signal isolator and a data acquisition module are adopted for signal acquisition; for a gas alarm instrument with a communication interface, a serial port server is used for acquisition, and theacquired signal is sent to a switch. The system comprises a real-time monitoring module, an alarm statistics module, a point inspection management module, a statistics report module and a content monitoring image of a point inspection record report, so that a user can perform centralized monitoring. The system has the advantages that the system achieves the tracking and management of the use condition of the on-site gas alarm apparatus, so that safety management personnel in an office can monitor and manage the gas leakage condition of a whole plant and the operation condition of the alarm apparatus through a computer, thereby effectively improving the safety management efficiency and the safety management level. After the system is put into use, the gas poisoning accidents do not occur, the design objective of the system is achieved, and an ideal effect is achieved.

Description

technical field [0001] The invention relates to the technical field of ironmaking safety equipment, in particular to a centralized monitoring system and method for a gas alarm instrument in an ironmaking plant. Background technique [0002] According to Article 6.1.29 of the "Standardized Evaluation Standards for Safety Production in Metallurgical Enterprises (Ironmaking)", the blast furnace tuyere platform, large platform for furnace top maintenance, hot blast stove operation platform, coal injection drying furnace, gravity dust collector, and dust removal in the casthouse in front of the furnace Fixed carbon monoxide monitoring and alarming devices (gas alarming devices) should be installed on the operating platforms of gas detectors and other gas purification equipment and facilities. The ironworks of Liuzhou Iron and Steel Co., Ltd. has a wide range of sites. Combined with the site environment and standard requirements, there are more than 250 sets of gas alarms installe...

AI Technical Summary

Problems solved by technology

As most of the blast furnaces enter the late stage of furnace operation, the phenomenon of gas leakage increases, the gas alarm device alarms frequently, and there are occasional gas poisoning accidents among the on-site staff

In addition, the safety management personnel went to the site for inspections many times and found that the post workers often did not pay enough attention to the alarm phenomenon of the gas alarm device, and did not take measures to control the hidden dangers of gas leakage as required, which buried hidden dangers for safety management.
