Specifically, for enterprises with toxic gas diffusion danger sources, management and maintenance of emergency evacuation basic data can be realized in emergency preparation and management stages, such as entry, update and supplement of necessary emergency management information, and basic data support is provided for emergency evacuation rescue under accident conditions. The emergency evacuation base data may include a vector map of an enterprise (e.g., a petrochemical enterprise), geographic information data (which may take the form of aerial imagery and may be merged with the vector map), operator and manager information for various production facility zones, and the like. The vector map data can adopt an editable space data open file format, is drawn and managed in a mode of a plurality of layers, and can comprise position information of an enterprise internal production device, equipment, an enterprise operation part and an operation part, houses, roads, material storage points, emergency evacuation difficulty avoidance points and the like.
For example, a GIS (Geographic Information System) technology may be used to obtain a vector map of Geographic Information about a petrochemical enterprise. In order to ensure scientific and dynamic display of emergency evacuation routes, a vector map covering the geographic information of the whole enterprise needs to be constructed. The geographic information of petrochemical enterprises is generally formed by superposing a high-definition aerial image map and a thematic vector map. The aerial photography image map can be replaced by a commercial satellite image map, and the thematic vector map is used for indicating position information of an enterprise internal production device, equipment, an enterprise operation part and an operation part, house, roads, material storage points, emergency evacuation difficulty avoidance points and other information.

In the embodiment of the present invention, the leakage accident source location information of the toxic gas leakage mainly refers to a specific production apparatus that acquires the toxic gas leakage. And several manufacturing facilities used to perform a certain process flow are generally referred to within an enterprise as a manufacturing facility area. However, the present invention is not limited to this, and an area where a specific production apparatus is located may be referred to as a production apparatus area.
The mobile terminal used by the field personnel can be connected with (for example, connected to a network) the enterprise emergency command system, and the field personnel can transmit the position information of the leakage accident source of the toxic gas leakage to the enterprise emergency command system through the mobile terminal. And the position information of the leakage accident source of the toxic gas leakage can be acquired through a telephone alarm way of field personnel.
For example, a complete petrochemical enterprise emergency command system and emergency mobile terminal software can be constructed. The emergency command system can be integrated with other accident emergency command systems of an enterprise into the same set of emergency command center equipment. For example: a large screen is used as a display carrier, and comprehensive display and decision command of emergency evacuation information are realized based on a GIS. The emergency command system is provided with a toxic gas leakage alarm receiving and processing module.
In a production device area where toxic gas leakage easily occurs in an enterprise, emergency mobile terminals can be equipped for field personnel (which can include operating personnel, management personnel and maintenance personnel) in the production device area, such as: the APP matched with the emergency command system can be downloaded at the mobile phone intelligent terminal. Or a special mobile terminal which is pre-configured with emergency mobile terminal software can be configured, and the mobile terminal is provided with emergency mobile terminal software which can communicate with the emergency command system. When toxic gas leaks, the mobile terminal can be used as a carrier for emergency evacuation information uploading, instruction issuing and information query of accidents. The field personnel can communicate with the emergency command system through the mobile terminal to give an alarm to the enterprise emergency command center. For example: and clicking an alarm button on the mobile terminal to send an alarm signal to the emergency command center, starting an alarm receiving and processing module of the emergency command center, and determining the position information of the leakage accident source with toxic gas leakage by the emergency command center directly according to the received alarm signal. For example: reasonable terminal numbers can be configured in advance for mobile terminals of field personnel, each terminal number is provided with a determined production device area, and position information of a leakage accident source with toxic gas leakage can be determined in other suitable modes. The field personnel can also directly dial the telephone of the emergency command center to alarm. Other suitable alarm means may also be employed.
In addition, on-site personnel can directly input information such as accident units, accident devices, accident equipment, equipment accident damage positions and damage degrees, accident substances, current working states of the accident devices and the like, wherein toxic gas leaks.

In the embodiment of the invention, the enterprise geographic information, the real-time meteorological data and the leakage accident source position information are imported into a preset Gaussian smoke mass integral model so as to dynamically simulate the toxic gas leakage diffusion condition, and the toxic gas leakage diffusion condition is displayed based on a GIS platform.
For example, the gaussian smoke group integral model may be packaged into a callable function method, and development and calling are performed through a main GIS platform API (Application Programming Interface), so that the gaussian smoke group integral model is effectively combined and applied in a B/S system (Browser/Server, information distribution system) with the geographic information page of the vector map in step S100. And simultaneously, according to the application requirements of the model, automatically reading important parameters in the enterprise geographic information, the real-time meteorological data, the position information of the leakage accident source and the like, such as the longitude and latitude coordinates of the leakage accident source, the environmental stable wind direction, the wind speed, the effective height of the leakage accident source, the leakage rate in the diffusion process and the like.

For example: the G805 production facility of the current 26-unit tank field has toxic gas leakage, and the toxic gas leakage accident affects the 23, 25, 26 and 27-unit tank fields in fig. 2, and the degree of the effect is shown by three dark and light ellipses (roughly in the diagonal direction of the connecting line between the lower left and the upper right in the figure) in the figure, wherein the dark elliptic region at the innermost side shows the maximum degree of the effect, and related personnel (including operators, managers and the like) in the affected production facility regions (including the 23, 25, 26 and 27-unit tank fields) need to be evacuated to an emergency evacuation point as soon as possible.
And S500, determining personnel evacuation paths corresponding to the production device areas in real time according to the real-time influence degree, the leakage accident source position and the vector map.

For example, referring to fig. 2 again, the emergency evacuation point at the lower right corner of the drawing is the finally determined optimal evacuation point, and an optimal evacuation path from the central point of the production facility area to the emergency evacuation avoidance point is respectively given for the 23/25/26/27 unit tank areas, for example: the arrowed lines of the implementation in fig. 2.
