When the computer program is executed by a processor, it is used to implement the first aspect of the present invention and various methods that may be involved in the first aspect.

[0060] The beneficial effects of the present invention are as follows:

[0061] 1. The present invention will determine different basic routes according to the different environments of the coal chemical equipment and different staff members, so as to facilitate the rapid evacuation of the staff members, and will optimize the basic routes according to the actual conditions of the equipment placement, so that the present invention can customize and generate corresponding evacuation routes according to the actual conditions of different employee ends. The present invention will determine the environmental attributes of the abnormal equipment. If the environmental attributes are restricted attributes, the corresponding target route strategy will be called to generate a restricted basic route corresponding to each employee end. If the environmental attributes are open attributes, the corresponding radial route strategy will be called to generate an open basic route corresponding to each employee end, so that the present invention can generate different basic routes for evacuation according to the actual environmental conditions, and in combination with the situation where there is equipment blocking during the route process, the corresponding basic routes will be optimized to obtain the corresponding evacuation video. The present invention will customize and generate evacuation routes corresponding to each employee end according to the actual conditions, so as to facilitate rapid response and timely evacuation of personnel.

[0062] 2. The present invention will monitor the parameters of coal chemical equipment through the mechanism model, locate abnormal equipment in time, and generate different basic routes according to the different environments where the equipment is located, so as to facilitate timely evacuation of personnel. When the present invention determines that multiple monitoring parameters of the equipment meet the parameter judgment group, the corresponding equipment will be automatically marked as abnormal equipment. And the present invention will call the corresponding strategy according to the environment where the abnormal equipment is located to generate a basic path that is adapted to the actual situation. When the environmental attribute is judged to be a restricted attribute, due to the ability of the confined space to limit the diffusion of gas, harmful gases accumulate in the space under abnormal circumstances, so that the entire confined space is identified as a dangerous area, then the regional image of the restricted area where the abnormal equipment is located is called, that is, the restricted map, and the judgment distance between the multiple exit positioning points of the personnel positioning point in the restricted map is determined, and the one with the shortest judgment distance is selected as the safety positioning point of the employee end, and the safety positioning point is connected with the personnel positioning point to obtain the restricted basic route corresponding to the employee end. When the present invention determines that the environmental attribute is an open attribute, since gases and substances are usually easier to diffuse and disperse in open spaces, harmful substances under abnormal conditions will not maintain high concentrations in the entire area, but will have an impact around the equipment. The open map where the abnormal equipment is located and the evacuation positioning points of the personnel within the impact range are retrieved to generate an initial ray route with the abnormal positioning point as the endpoint and passing through the evacuation positioning point, and the intersection of the initial ray route and the circular impact area is used as the evacuation positioning point to generate a corresponding open basic route, so that the present invention can generate a basic route that is adapted to the environment in which the equipment is located and matches the corresponding employee end according to actual conditions, so as to facilitate the rapid evacuation of personnel.

[0063] 3. The present invention takes into account that workers may encounter obstacles from other equipment while walking on the basic path. Therefore, multiple recommended routes will be determined based on the shape of the actual equipment, and the shortest route will be displayed, so that the evacuation route finally generated is in line with reality while providing employees with multiple alternative routes to cope with complex situations. The present invention will obtain the equipment positioning points of all coal chemical equipment to optimize the restricted basic route and / or the open basic route, retrieve the top view of the equipment between the optimized starting point and the optimized end point in the restricted basic route and / or the open basic route, and determine the optimized positioning point corresponding to the maximum angle, connect it with the optimized starting point, and continuously check whether there is equipment obstruction between the optimized positioning point and the optimized end point, until there is no equipment obstruction, directly connect to generate multiple recommended routes, and highlight the shortest direct route among them, thereby generating an evacuation route, and the present invention can customize and generate related routes for employees with different attributes based on the employee attributes in the open attributes.

[0069] The technical solution of the present invention is described in detail with specific embodiments below. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0070] The present invention provides a coal chemical safety diagnosis method based on a mechanism model, such as Figure 1 As shown, steps S1-S4 are included:

[0071] S1, determining abnormal equipment based on the judgment information of monitoring parameters of all coal chemical equipment based on the mechanism model, and obtaining environmental attributes of the abnormal equipment, wherein the environmental attributes include restricted attributes and open attributes.

[0072] In actual applications, the coal chemical processing process usually has multiple steps, and the equipment of each process has different characteristics and requirements. Some processes need to be carried out in confined spaces to ensure efficient reactions and process control, such as high-pressure synthesis reactions, catalyst reactions, etc., while other processes are suitable for open spaces to achieve large-scale production. Therefore, the environment in which the coal chemical equipment is located can be a space with confined properties, such as a partially closed place, and the environment in which the coal chemical equipment is located can be an open space with open properties, such as an open air place.

[0073] Therefore, the server will determine the corresponding coal chemical equipment as abnormal equipment based on the judgment information of the monitoring parameters of all coal chemical equipment based on the mechanism model, and obtain the environmental attributes of the abnormal equipment.

[0074] Among them, the mechanism model is an accurate mathematical model established according to the internal mechanism of the object, the production process or the transfer mechanism of the material flow. The mechanism model can be used to judge whether each device in the system is safe. The mechanism model contains a storage unit and a judgment unit. The storage unit is used to store the parameter judgment group, and the judgment unit is used to judge whether the monitoring parameters of each coal chemical equipment are abnormal. The mechanism model can be a processor, and the processor can be a central processing unit, or other general-purpose processors, application-specific integrated circuits, etc., for executing corresponding judgment steps.

[0075] The mechanism model has a parameter judgment group for each monitoring dimension of each device. For example, the monitoring dimension can be temperature, pressure, etc., which is convenient for subsequent automatic judgment of whether the device is abnormal.

[0076] The monitoring parameters are parameters for monitoring coal chemical equipment. The environmental attributes include restricted attributes and open attributes. The restricted attributes are attributes corresponding to restricted spaces, and the open attributes are attributes corresponding to open spaces.

[0077] In some embodiments, step S1 (determining abnormal equipment based on the comparison information of monitoring parameters of all coal chemical equipment based on the mechanism model) includes S11-S12:

[0078] S11, obtaining a parameter judgment group of each of the coal chemical equipment in the mechanism model, and a plurality of monitoring parameters of the corresponding coal chemical equipment.

[0079] It should be noted that the mechanism model pre-sets threshold parameters corresponding to all monitoring dimensions of various types of coal chemical equipment, such as parameters corresponding to high temperature of the equipment, parameters corresponding to high pressure of the equipment, etc. All threshold parameters of each coal chemical equipment are counted to obtain a parameter judgment group.

[0080] It is understandable that the server will obtain the parameter judgment group of each coal chemical equipment in the mechanism model and multiple monitoring parameters of the coal chemical equipment.

[0081] It is not difficult to understand that the parameter judgment group is a plurality of threshold parameters for judging the abnormality of coal chemical equipment. For example, equipment A is in a high temperature state when it exceeds 500°C, and is in a high pressure state when it exceeds 50MPa (megapascals). 500°C and 50MPa are the threshold parameters corresponding to equipment A respectively. The combination of (500°C, 50MPa) is the parameter judgment group corresponding to coal chemical equipment A.

[0082] S12, determining that a plurality of monitoring parameters satisfy the parameter judgment group, and treating the corresponding coal chemical equipment as abnormal equipment.

[0083] It should be noted that the present invention can determine whether each device is safe through the mechanism model, and the mechanism model has a parameter judgment group for each device, such as detecting high temperature, high pressure, leakage and deformation, etc. Some devices may have short-term abnormalities during startup, shutdown or special operation stages, and the mechanism model may take these special stages into account to avoid false alarms.

[0084] Therefore, the mechanism model usually considers multiple parameters, not just a single parameter. The integration of information from multiple parameters can improve the accuracy of the judgment of the equipment status. Only when multiple parameters are abnormal at the same time can it be judged as an equipment abnormality.

[0085] It is understandable that the server will determine that multiple monitoring parameters satisfy the parameter judgment group and treat the corresponding coal chemical equipment as abnormal equipment.

[0086] For example, if device A reaches a high temperature exceeding 500°C and a high pressure exceeding 50MPa (megapascals), device A will be identified as an abnormal device.

[0087] S2, according to the restricted attribute, retrieve the restricted map where the corresponding abnormal device is located, and obtain the exit positioning point of the safe exit area in the restricted map, select and process the corresponding exit positioning point based on the target route strategy, and obtain the restricted basic route of each employee end.

[0088] It should be noted that due to the different environmental attributes of the abnormal equipment, the evacuation routes of the dangerous environment are different. The space corresponding to the restricted attribute is generally a partially enclosed area. When the coal chemical equipment in this area is abnormal, the entire space is dangerous. Therefore, it is necessary to evacuate all personnel in the space with restricted attributes, that is, the confined space. And because there are multiple safe exits in the partially enclosed space, when evacuating, the safe exit closest to each employee end will be selected to generate the evacuation route corresponding to the employee end.

[0089] It is understandable that the server will retrieve the corresponding area map where the abnormal device is located as the restricted map according to the restricted attribute. For example, if the abnormal device A is in the space of restricted attribute, the area map corresponding to the space will be retrieved.

[0090] Furthermore, the exit positioning points of the safe exit area in the restricted map are obtained, and the corresponding exit positioning points are selected and processed through the target route strategy to obtain the restricted basic route of each employee.

[0091] In some embodiments, step S2 (calling the restricted map where the corresponding abnormal device is located according to the restricted attribute, and obtaining the exit location point of the safe exit area in the restricted map, selecting and processing the corresponding exit location point based on the target route strategy, and obtaining the restricted basic route of each employee terminal) includes S21-S25:

[0092] S21, according to the restricted attribute, retrieve a restricted graph where the corresponding abnormal device is located, wherein the restricted graph includes a plurality of safe exit areas.

[0093] It is understandable that the server will retrieve the area map where the abnormal device is located as the restricted map according to the restricted attribute, and the restricted map includes multiple safety exit areas.

[0094] Among them, the restricted map is a regional map where the environmental attributes of the abnormal equipment are restricted attributes, and the safe exit area is the entrance and exit area corresponding to the restricted attribute space.

[0095] For example, if the abnormal device A is in a confined space, then the area map A corresponding to the confined space where the device A is located is retrieved.

[0096] S22, acquiring the center points of the plurality of safety exit areas, and obtaining exit positioning points corresponding to the corresponding safety exit areas.

[0097] It is understandable that the server will automatically obtain the center points of multiple safety exit areas in the restricted map, thereby obtaining the exit positioning points corresponding to the corresponding safety exit areas.

[0098] It is not difficult to understand that the entrance and exit areas are generally regular areas, such as rectangles. Therefore, the center point corresponding to the area can be directly obtained as the exit positioning point, which is convenient for subsequent calculation of the distance between the personnel and the exit positioning point to locate the nearest exit positioning point and generate the corresponding evacuation route.

[0099] S23, determining a personnel positioning point corresponding to the employee terminal in the restricted map according to the positioning information of the employee terminal.

[0100] It is understandable that each employee terminal has a corresponding positioning device. For example, the positioning can be sent through the employee's mobile terminal. Therefore, the server will determine the positioning point corresponding to the corresponding employee terminal in the restricted map as the personnel positioning point based on the positioning information of the employee terminal.

[0101] S24, constructing a coordinate system in the restricted graph, and obtaining a plurality of judgment distances corresponding to the employee end according to the coordinates of the personnel positioning point and the coordinates of all the exit positioning points.

[0102] It is not difficult to understand that after determining the exit positioning points of all safety exit areas in the restricted map and the personnel positioning points corresponding to each employee, the safety exit area closest to each employee will be determined to generate the corresponding evacuation route.

[0103] Therefore, the server will construct a coordinate system in the restricted graph, so that the coordinates of the personnel positioning point and the coordinates of all the exit positioning points can be obtained, and calculations are performed based on the coordinates of the personnel positioning point and the coordinates of all the exit positioning points, so as to obtain multiple judgment distances of each employee end from multiple safety exit areas. It can be understood that the calculation method of the coordinates of the personnel positioning point and the coordinates of all the exit positioning points, and the calculation formula for calculating the distance between 2 points in the coordinate system are the prior art here and will not be repeated here.

[0104] S25, selecting and processing the corresponding exit positioning point according to the determined distance to obtain the restricted basic route of each employee terminal.

[0105] It is not difficult to understand that after obtaining the judgment distance corresponding to each employee end and all safety exit areas, the exit positioning point with the shortest distance will be selected to generate the corresponding restricted basic route.

[0106] In some embodiments, step S25 (selecting and processing the corresponding exit location point according to the determined distance to obtain the restricted basic route of each employee terminal) includes S251-S252:

[0107] S251, selecting the exit positioning point corresponding to the minimum judgment distance as the safety positioning point corresponding to the employee terminal.

[0108] It is understandable that the server will select the exit positioning point corresponding to the minimum judgment distance as the safety positioning point corresponding to the employee terminal.

[0109] S252: Connect the personnel positioning point and the safety positioning point to obtain a restricted basic route of each employee.

[0110] It is understandable that after determining the safety positioning point closest to the personnel positioning point, the personnel positioning point will be connected with the safety positioning point to obtain the restricted basic route of each employee end.

[0111] For example, Figure 2 As shown, abnormal equipment A appears in the restricted diagram A corresponding to the confined space, and there are personnel No. 1 and personnel No. 2 in the area diagram A, as well as safety exit area e and safety exit area t. Select the safety positioning point of safety exit area e closest to personnel No. 1 to connect the restricted basic route corresponding to personnel No. 1, and select the safety positioning point of safety exit area t closest to personnel No. 2 to connect the restricted basic route corresponding to personnel No. 2.

[0112] Through the above implementation, the present invention can automatically determine the evacuation route with the shortest distance to each employee, so that the personnel can quickly respond to the evacuation command and leave the danger zone more quickly.

[0113] S3, based on the open attribute, retrieve the open graph where the abnormal device is located, obtain the abnormal location point of the abnormal device in the open graph, connect the abnormal location point based on the radial route strategy, and obtain the open basic route of each employee end.

[0114] It should be noted that due to the different environmental properties of the abnormal equipment, the routes for evacuating the dangerous environment are different. The space corresponding to the open attribute (i.e., open space) is generally an area that allows relatively free movement and ventilation. Since gases and substances are usually easier to diffuse and disperse in open spaces, harmful substances under abnormal conditions will not maintain high concentrations in the entire area, but will have an impact around the equipment. Therefore, it is only necessary to evacuate personnel in the surrounding area of ​​the corresponding abnormal equipment in the open space. Moreover, since personnel can move freely, when it is determined that abnormal equipment has occurred, personnel cannot determine the evacuation route and direction, and there is a situation where they are closer to the abnormal equipment.

[0115] Therefore, the server retrieves the area map where the corresponding abnormal device is located as the open map based on the open attribute. For example, if the abnormal device B is in the space of the open attribute, the area map corresponding to the space is retrieved.

[0116] Furthermore, the abnormal positioning points of the abnormal equipment in the open graph are obtained, and the abnormal positioning points are connected based on the radial route strategy to obtain the open basic route of each employee end.

[0117] In some embodiments, step S3 (calling the open graph where the abnormal device is located based on the open attribute, obtaining the abnormal location point of the abnormal device in the open graph, and connecting the abnormal location point based on the radial route strategy to obtain the open basic route of each employee terminal) includes S31-S34:

[0118] S31, based on the open attribute, retrieve the open graph where the corresponding abnormal device is located, and obtain the positioning point corresponding to the positioning information of the abnormal device in the open graph as the abnormal positioning point, and the positioning point corresponding to the positioning information of each employee terminal as the personnel positioning point.

[0119] It is understandable that the server will retrieve the map of the area where the abnormal device is located as an open map based on the open attribute.

[0120] The open graph is a regional graph where the environment attribute of the abnormal device is open.

[0121] For example, if the abnormal device B is located in an open space, then the area map B corresponding to the open space where the device B is located is retrieved.

[0122] S32, obtaining the impact distance corresponding to the abnormal device, and obtaining a circular impact area based on the abnormal positioning point as the center and the impact distance as the radius.

[0123] It should be noted that each type of abnormal equipment has a corresponding impact distance, wherein the impact distance is a distance preset manually based on the model of each coal chemical equipment. For example, when a gas leak occurs in equipment B, the impact distance is 100 meters nearby.

[0124] Therefore, the server obtains the impact distance corresponding to the abnormal device, and uses the abnormal positioning point of the abnormal device as the center of the circle and the impact distance as the radius, thereby obtaining a circular impact area corresponding to the abnormal device.

[0125] S33, acquiring all the personnel positioning points within the circular influence area as evacuation positioning points, and the employee ends corresponding to the evacuation positioning points as evacuation ends.

[0126] It should be noted that since gases and substances are generally easier to diffuse and disperse in open spaces, harmful substances under abnormal conditions will not maintain high concentrations in the entire area, but will have an impact around the equipment. Therefore, it is only necessary to evacuate personnel in the surrounding areas of the corresponding abnormal equipment in the open space.

[0127] Therefore, the server will obtain the personnel positioning point within the circular influence area as the evacuation positioning point, and the employee end corresponding to the evacuation positioning point as the evacuation end.

[0128] S34, obtaining an open basic route of each evacuation end according to the connection line between the evacuation positioning point and the abnormal positioning point.

[0129] It is understandable that the server will connect the evacuation positioning point and the abnormal positioning point to determine the open basic route of each evacuation end.

[0130] In some embodiments, step S34 (obtaining the open basic routes of each evacuation end according to the connection line between the evacuation positioning point and the abnormal positioning point) includes S341-S343:

[0131] S341, generating an initial ray path corresponding to each evacuation end and having the abnormal positioning point as an endpoint according to a connection line between the corresponding evacuation positioning point and the corresponding abnormal positioning point.

[0132] It should be noted that, since abnormal equipment in an open space may have an impact on the surroundings, it is only necessary to evacuate personnel in the surrounding area corresponding to the abnormal equipment in the open space.

[0133] Therefore, the server will determine the evacuation positioning points around the abnormal equipment, and connect the surrounding evacuation positioning points with the corresponding abnormal positioning points to generate an initial ray route with the abnormal positioning point as the endpoint.

[0134] It is not difficult to understand that the initial ray route is a ray route that takes the abnormal positioning point as an endpoint and passes through the evacuation positioning point.

[0135] S342: Determine the intersection of the initial ray path and the outline of the circular impact area as an evacuation positioning point.

[0136] It can be understood that the intersection of the initial ray route and the abnormal circular impact area of ​​the abnormal equipment is determined as the evacuation positioning point.

[0137] S343, obtaining an open basic route of each evacuation end according to the connection line between the evacuation positioning point and the corresponding evacuation positioning point.

[0138] It is understandable that the server will obtain the open basic routes of each evacuation end according to the connection between the evacuation positioning point and the corresponding evacuation positioning point.

[0139] For example, Figure 3 As shown, an abnormal device B appears in the open graph B corresponding to the open space, and there is a person No. 3 in the area graph B. The abnormal positioning point of the abnormal device B is connected with the person No. 3 to obtain an initial ray route with the abnormal positioning point B as the endpoint and passing through the personnel positioning point of the person No. 3, and intersecting with the outline of the circular influence area of ​​the abnormal device B to obtain the evacuation positioning point, and connecting the evacuation positioning point and the evacuation positioning point of the person No. 3 to obtain the open basic route of the person No. 3.

[0140] S4, calling the route optimization strategy to optimize the restricted basic route and / or the open basic route, and obtaining the evacuation route to send to the corresponding employee terminal.

[0141] In actual applications, since employees may be evacuated along restricted basic routes and / or open basic routes and other coal chemical equipment may block the routes, it is necessary to escape from the blocked coal chemical equipment.

[0142] Therefore, the present invention calls up a route optimization strategy to optimize the restricted basic route and / or the open basic route using the outline of the blocked coal chemical equipment to generate an evacuation route that matches the actual situation.

[0143] In some embodiments, step S4 (calling the route optimization strategy to optimize the restricted basic route and / or the open basic route, obtaining the evacuation route and sending it to the corresponding employee terminal) includes S41-S46:

[0144] S41, obtaining the personnel positioning point in the restricted basic route as the optimization starting point, and the safety positioning point as the optimization end point. And / or,

[0145] It is understandable that the server will obtain the personnel positioning point in the restricted basic route as the optimization starting point and the safety positioning point as the optimization end point, and will subsequently optimize the route based on the equipment blocking the middle of the route.

[0146] S42, acquiring the evacuation positioning point in the open basic route as an optimization starting point, and the evacuation positioning point as an optimization end point.

[0147] It is understandable that the server will obtain the evacuation positioning point in the open basic route as the optimization starting point, and the withdrawal positioning point as the optimization end point, and will subsequently optimize the route based on the equipment blocking the middle of the route.

[0148] S43, obtaining the equipment location points of the coal chemical equipment in the restricted graph and / or the open graph.

[0149] It is not difficult to understand that the server will obtain the location points of the coal chemical equipment in the restricted graph and / or the open graph as the equipment location points.

[0150] S44, determining that the connection line between the optimization start point and the optimization end point does not have the equipment positioning point, and obtaining an evacuation route according to the connection line between the optimization start point and the optimization end point.

[0151] It can be understood that the line between the server optimization starting point and the optimization end point does not have the equipment positioning point, that is, there is no equipment obstruction in the restricted basic route and / or the open basic route, so the optimization starting point and the optimization end point are directly connected to obtain the evacuation route.

[0152] S45, determining that the connection line between the optimization starting point and the optimization end point has the equipment positioning point, and generating an evacuation route according to the equipment positioning point, the optimization starting point and the optimization end point.

[0153] It can be understood that the server determines that the device positioning point is located at the line between the optimization start point and the optimization end point, that is, there is a device obstruction in the restricted basic route and / or the open basic route.

[0154] Therefore, an evacuation route is generated based on the equipment positioning point, the optimized starting point, and the optimized end point.

[0155] In some embodiments, step S45 (determining that the line between the optimization start point and the optimization end point has the equipment positioning point, and generating an evacuation route according to the equipment positioning point, the optimization start point and the optimization end point) includes S451-S4510:

[0156] S451, determining that a connection line between the optimization start point and the optimization end point has the device positioning point, and using the corresponding device positioning point as a blocking positioning point.

[0157] It is understandable that the server will determine that there is a device positioning point at the connection line between the optimization start point and the optimization end point, and use the corresponding device positioning point as a blocking positioning point. It is also understandable that when determining that there is a blocking device positioning point, the corresponding device positioning point is used as a blocking positioning point.

[0158] S452, retrieve a top view outline of the coal chemical equipment corresponding to the blocking positioning point closest to the optimization starting point.

[0159] It is understandable that when there are one or more blocking positioning points, that is, there are one or more equipment blocking, it is necessary to select the blocking positioning point closest to the optimization starting point to optimize the route first. After the optimization is completed, the new route generated has the ability to directly bypass the subsequent blocking positioning points.

[0160] Therefore, the server will retrieve the top-down outline of the coal chemical equipment corresponding to the blocking positioning point closest to the optimization starting point.

[0161] S453: Obtain a segmentation line according to a line connecting the optimization start point and the optimization end point.

[0162] S454, segmenting the top-view contour image based on the segmentation line, and counting the contour pixel points on one side of the segmentation line in the top-view contour image to obtain a first pixel point set, and counting the contour pixel points on the other side of the segmentation line to obtain a second pixel point set.

[0163] It is not difficult to understand that when there is an obstructing coal chemical equipment, personnel need to bypass the equipment and can choose to bypass one side or the other side of the equipment, so two paths will be generated, and then a subsequent judgment will be made whether there is still equipment blocking the way.

[0164] Therefore, the server segments the top-view contour image based on the dividing line, and counts the contour pixel points on one side of the dividing line in the top-view contour image to obtain a first pixel point set, and the contour pixel points on the other side of the dividing line to obtain a second pixel point set.

[0165] S455: Connect the optimization starting point and all the contour pixel points in the first pixel point set to obtain a first connecting line.

[0166] It can be understood that the optimization starting point is connected to all the contour pixel points in the first pixel point set respectively to obtain the first connecting line.

[0167] S456: Connect the optimization starting point and all the contour pixel points in the second pixel point set to obtain a second connecting line.

[0168] It can be understood that the optimization starting point is connected to all the contour pixel points in the second pixel point set respectively to obtain the second connecting line.

[0169] S457, obtaining a first angle according to the first connecting line and the dividing line, and obtaining a second angle according to the second connecting line and the dividing line.

[0170] S458, selecting the contour pixel point corresponding to the largest first angle as the first optimized positioning point, and selecting the contour pixel point corresponding to the largest second angle as the second optimized positioning point.

[0171] It is understandable that the server will select the contour pixel point corresponding to the largest first angle as the first optimization positioning point, and select the contour pixel point corresponding to the largest second angle as the second optimization positioning point, that is, select points on both sides of the top-down contour map of the blocked coal chemical equipment to facilitate subsequent connection with the optimization starting point to bypass the blocked coal chemical equipment.

[0172] S459, connecting the first optimization positioning point and the second optimization positioning point with the corresponding optimization starting point, and taking the first optimization positioning point and the second optimization positioning point as the current optimization starting point, repeating the above steps until there is no device positioning point at the connection line between the corresponding optimization starting point and the optimization end point, connecting the optimization starting point and the optimization end point, and generating multiple recommended routes.

[0173] It can be understood that the first optimization positioning point and the second optimization positioning point are connected to the corresponding optimization starting point, and the first optimization positioning point and the second optimization positioning point are used as the current optimization starting point, and the above steps are repeated until there is no device positioning point at the connection line between the corresponding optimization starting point and the optimization end point, and the optimization starting point and the optimization end point are connected to generate multiple recommended routes.

[0174] like Figure 4As shown, the top view outline of the coal chemical equipment may be an irregular shape. The server will determine the two points on the outermost side of the top view outline relative to the dividing line (the line connecting the optimization starting point and the optimization end point) as the first optimization positioning point and the second optimization positioning point, thereby generating two recommended routes. If there are still obstructing equipment from the first optimization positioning point and the second optimization positioning point to the optimization end point, the first optimization positioning point and the second optimization positioning point will continue to be generated until there is no obstructing coal chemical equipment.

[0175] S4510, selecting the shortest route among the plurality of recommended routes as a direct route, and selecting the remaining recommended routes as alternative routes, highlighting the direct route, and generating an evacuation route.

[0176] S46, sending the evacuation route to the corresponding employee terminal.

[0177] Through the above implementation mode, the present invention will recommend the shortest route as the direct route, and the remaining recommended routes as alternative routes, and highlight the direct route, so that the user can choose the shortest direct route for evacuation. If an emergency occurs, the alternative route can also be selected for evacuation. The present invention can adopt a flexible and effective evacuation route, thereby improving the flexibility and practicality of responding to emergencies.

[0178] Based on the above embodiment, it also includes A1-A3:

[0179] A1, obtaining the employee attributes of the evacuation end, wherein the employee attributes include maintenance attributes and operation attributes.

[0180] It is understandable that if there are maintenance workers in the circular impact area, if it is found that the abnormal equipment can be repaired by personnel, the server will obtain the employee attributes of the evacuation end, and the employee attributes include maintenance attributes and operation attributes. The maintenance attribute is the attribute corresponding to the operating employee, and the operation attribute is the attribute corresponding to the maintenance employee.

[0181] A2, determining that the employee attribute of the evacuation end is a maintenance attribute, and using the evacuation positioning point corresponding to the evacuation end as a maintenance positioning point.

[0182] It is understandable that the server determines that the employee attribute of the evacuation end is a maintenance attribute, that is, there are maintenance workers in the circular impact area, and then uses the evacuation positioning point of the corresponding evacuation end as a maintenance positioning point.

[0183] A3, generating a maintenance route according to the connection line between the abnormal positioning point and the maintenance positioning point, and sending the maintenance route to the evacuation end corresponding to the maintenance positioning point.

[0184] It is understandable that the server will generate a maintenance route based on the connection between the abnormal positioning point and the maintenance positioning point, and send the maintenance route to the evacuation end corresponding to the maintenance positioning point.

[0185] It is not difficult to understand that the maintenance location point and the abnormal location point corresponding to the maintenance worker will be connected to generate a maintenance route, and the maintenance route will be sent to the evacuation end corresponding to the maintenance work.

[0186] In order to better realize the coal chemical safety diagnosis method based on the mechanism model provided by the present invention, the present invention also provides a coal chemical safety diagnosis system based on the mechanism model, such as Figure 5 As shown, including:

[0187] A judgment module, used to determine abnormal equipment based on the judgment information of the monitoring parameters of all coal chemical equipment based on the mechanism model, and obtain the environmental attributes of the abnormal equipment, wherein the environmental attributes include restricted attributes and open attributes;

[0188] A restricted processing module is used to retrieve the restricted map where the abnormal device is located according to the restricted attribute, obtain the exit location point of the safe exit area in the restricted map, select and process the corresponding exit location point based on the target route strategy, and obtain the restricted basic route of each employee terminal;

[0190] The optimization module is used to call the route optimization strategy to optimize the restricted basic route and / or the open basic route, and obtain the evacuation route and send it to the corresponding employee terminal.
