Abstract
The invention provides a safety monitoring device for chemical production. In a chemical production process, a great number of dangerous chemicals are related, the requirements of a production process are harsh, and production devices are large-sized, continuous and automatic, so that an accident can lead to grave consequences. The safety monitoring device comprises a group of sensors (1) arranged at each monitoring point respectively. The sensors are connected with controllers (2) which are connected with data transmission units (3). The data transmission units are connected with a historical data server (5) through a load balancer (4). The historical data server is connected with an industrial personal computer (6). The safety monitoring device is used for monitoring potential safety hazards in the chemical production process.
Description
Technical field
The present invention relates to the safety monitoring device in a kind of chemical process.
Background technology
Hazardous chemical quantity is many, manufacturing technique requirent is harsh owing to relating to for chemical process, and the maximization of process units, serialization and robotization, in case have an accident, consequence will be extremely serious.Therefore, safety problem in chemical process in occupation of very important position.
Historical experience shows, improves the enterprise security production level nothing more than two approach: one, carry out deeply comprehensively safety analysis and verification, accomplish and prevent trouble before it happens, promptly set up effective prevention system; Two, when danger really takes place, make great efforts to improve operative employee's emergency processing ability, promptly set up the online in real time protection system.Prevention is two complementary links in the safety in production with protection.Effectively preventive means can be got rid of potential safety hazard early, and the emergent and ability that pulls through of enterprise when preventive means has strengthened dangerous the generation greatly in real time.
In the field of safety engineering, the problem that at first will face prevents trouble before it happens exactly.Though a cover favorable protection system is no doubt important, if expection just can be analyzed, pinpoint the problems, it is the most conceivable results of people that danger was eliminated in the initial period.Safety evaluation that Here it is subject matter to be solved.
Summary of the invention
The objective of the invention is provides a kind of Chemical Manufacture safety monitoring device to the problem of above-mentioned existence, estimates tap/dip deep into chemical plant installations potential potential safety hazard in service through comprehensive, real-time computing machine automatic safe.In real time dangerous reason is diagnosed the location.
Above-mentioned purpose realizes through following technical scheme:
The Chemical Manufacture safety monitoring device; Comprise the one group of sensor that is installed in each monitoring point; Described sensor connects controller; Described controller connects data transmission unit, and described data transmission unit connects historic data server through load equalizer, and described historic data server connects industrial computer.
