Embodiment 1

[0018] The invention relates to a method for alarming process parameters when a chemical plant is started, such as figure 1 As shown, it includes the following steps: (1) input the activation condition, termination condition, process alarm limit and condition confirmation alarm value of the process parameters into the configuration table in the server through the configuration tool; (2) input the DCS real-time data through the data acquisition tool The real-time data table of the server; (3) compare the real-time data with the activation condition, termination condition, process alarm limit and condition confirmation alarm value in the inference engine, and input meaningful comparison results into the result table; (4) The customer service end reads the data from the result table of the server, and according to the comparison result, an alarm is issued. When an alarm is issued, the consequences of exceeding the limit and handling suggestions are automatically popped up. The saf...

Abstract

The invention relates to a technological parameter alarming method during the starting of a chemical engineering device, and mainly solves the problem that in the prior art, the chemical engineering device is easy to operate mistakenly and low in security coefficient when starting. The problem is well solved by the technical scheme that the technological parameter alarming method during the starting of the chemical engineering device comprises the following steps of: 1, inputting activation conditions, ending conditions, process alarm limit and condition confirmation alarm value of technological parameters into a configuration list in a server; 2, inputting DCS real-time data into a real-time data list in the server; 3, performing comparison in an inference engine, and inputting the significant comparison result into a result list; 4, reading data from the result list of the server by a client, and alarming according to the comparison result; the technological parameter alarming method during the starting of the chemical engineering device can be applied to the technological parameter alarming when the chemical engineering device starts.

Description

technical field [0001] The invention relates to a method for alarming process parameters when a chemical plant is started. Background technique [0002] The chemical plant is becoming increasingly large-scale, the coupling relationship between each link of the plant is getting closer, and the driving process is becoming more and more complicated, which brings more and more challenges to the safety of driving. [0003] The start-up of a chemical plant includes multiple processes, such as heating up, boosting pressure, establishing liquid level, establishing reflux, establishing circulation, and so on. Every step of operation requires strict conditions, and once it is not operated properly, it may lead to abnormal accidents, and there are many accidents caused by this. According to the survey of foreign professional institutions, accidents during driving account for more than 20% of the accidents in the entire chemical production. [0004] In China, there are few devices tha...
