Example Embodiment

[0022] Example one:

[0023] An online safety diagnosis and accident handling guidance method for chemical plants, such as figure 1 As shown, including the following steps:

[0024] A') According to the chemical plant GIS model, the area between chemical plant equipment and equipment and buildings is divided into sub-areas, and an area table is established for each sub-area. The area table includes area location, adjacent equipment, adjacent area, adjacent building and Status information, the status information of the area table includes temperature, hazardous gas concentration, hazardous gas type, wind direction and wind force. Such as figure 2 As shown, the method of dividing sub-regions includes: A'1) importing a chemical plant GIS model, removing pipes and equipment whose volume is less than a set threshold; A'2) establishing an external cuboid of the equipment; A'3) connecting a cuboid and chemical Fill the rectangular parallelepiped area between the factory buildings so th...

Example Embodiment

[0034] Embodiment two:

[0035] This embodiment is a further improvement on the basis of the first embodiment. In this embodiment, in step A'5, a second side length threshold is also set, and the second side length threshold is that an accident occurring in the chemical plant area is dangerous When a gas leaks, the distance that the leakage center spreads in time T under no wind conditions; use the side length threshold and the second side length threshold respectively to divide and save the sub-regions; when a fire occurs in the chemical plant area, Use the sub-area corresponding to the side length threshold. When a dangerous gas leak occurs in the chemical plant area, use the sub-area corresponding to the second side length threshold. If a fire and a dangerous gas leak occur at the same time, select the side length threshold and the second side length The division of the sub-areas corresponding to the smaller value in the threshold. This embodiment adopts different side length...

Abstract

The invention relates to the technical field of chemical plant safety, in particular to a chemical plant online safety diagnosis and accident disposal guidance method and system, and the method comprises the following steps: A), building and storing a monitoring table and a plan, and entering a step B if an alarm is given; b) if the trigger condition is not satisfied, closing the alarm, otherwise,triggering the plan and the update table to update the corresponding alarm condition, and displaying the accident handling content; c) reading the monitoring data of the chemical plant in a period T,if the monitoring data meets an alarm condition, giving an alarm, improving the accident level by one level, and displaying the accident grading disposal content of the corresponding level; and D) ifthe monitoring data meets the release condition, releasing the alarm, and returning to the step A. The invention has the substantive effects of assisting the disposal of the accident, displaying thesub-region state of the chemical plant for the operator on duty, making a personnel evacuation scheme in a targeted manner, reducing the accident loss, and improving the personnel safety in the accident.

Description

technical field [0001] The invention relates to the technical field of chemical plant safety, in particular to a chemical plant online safety diagnosis and accident handling guidance method and system. Background technique [0002] The DCS system of a chemical plant is a system that controls the production process and is the most important control center of a chemical plant. 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 and process stations to control many control points in a production process, and the controllers are connected through the network and can exchange data. DCS is divided structurally, including process level, operation level and management level. Management level refers to the factory management information system. From the management level of DCS, the...
