Embodiment 1

[0021] An auxiliary disposal method for chemical plant emergencies based on electronic plans, such as figure 1 As shown, the present embodiment comprises the following steps: A) establishes an electronic plan, and the electronic plan includes object, accident type, plan content, tracking table, tracking trigger condition and release condition, and the tracking table record object tracks and monitors when the accident type occurs The data items are manually determined according to the plan and the structure of the chemical plant. The content of the plan includes the accident disposal method and the tracking disposal method. The tracking disposal method is the disposal method of the monitoring data items in the tracking table when the tracking trigger conditions are met. Execution: A1) Import the GIS model of the chemical plant, divide the area between the equipment of the chemical plant and between the equipment and the building into sub-areas, and establish a regional supervisi...

Embodiment 2

[0027] On the basis of the first embodiment, this embodiment further improves the setting of the side length threshold. On the basis of Embodiment 1, in step A15, a second side length threshold is also set, and the second side length threshold value is when the accident that occurs in the chemical plant area is a dangerous gas leakage, and under no wind conditions, the leakage center is at The distance spread within T time; respectively use the side length threshold and the second side length threshold to divide the sub-regions and save them separately; when a fire occurs in the chemical plant area, use the sub-area corresponding to the side length threshold, when the chemical plant area When dangerous gas leakage occurs, the sub-region corresponding to the second side length threshold is used, and if fire and dangerous gas leakage occur at the same time, the division of the sub-region corresponding to the smaller value between the side length threshold and the second side leng...

Abstract

The invention relates to the technical field of chemical plant safety supervision, in particular to an electronic-plan-based auxiliary disposal method for emergency accidents in a chemical plant. Theelectronic-plan-based auxiliary disposal method for the emergency accidents in the chemical plant comprises the following steps that (A) an electronic plan is established; (B) chemical plant DCS dataare read to obtain current monitoring data of the chemical plant, if the monitoring data of the chemical plant meets an alarm condition, a step C is carried out, otherwise, the step (B) is repeatedlycarried out; and (C) the electronic plan corresponding to the alarm condition is triggered, and the accident disposal method and a tracking table of the triggered electronic plan are displayed to operators on duty, latest chemical plant DCS data are read, if the data in the tracking table meets a tracking triggering condition, an alarm is issued, the corresponding tracking disposal method is displayed, and the step B is carried out for continue execution. The electronic-plan-based auxiliary disposal method for the emergency accidents in the chemical plant has the substantial effects that the efficiency and rationality of accident disposal are improved, the enlargement of the accidents can be found in time, and the status of chemical plant areas is tracked.

Description

technical field [0001] The invention relates to the technical field of chemical plant safety supervision, in particular to an electronic preplan-based auxiliary treatment method for chemical plant emergencies. Background technique [0002] The production process control of chemical plants has gone through manual operation control, conventional instrument control, computer centralized control and DCS control. Among them, DCS is the English abbreviation of Distributed Control System (Distributed Control System), also known as Distributed Control System. The main features of DCS are "decentralized control" and "centralized management". DCS usually uses several controllers, that is, process stations to control many control points in a production process, and the controllers are connected through the network and can exchange data. The production control operation adopts a computer operation station, which is connected to the controller through the network, collects production d...
