[0030] Embodiment 1

[0031] Figure 1 FIG. is a flowchart of an escape route determination method for a utility tunnel provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation where, without deploying equipment related to the geographic information system for the utility tunnel, the escape route can be quickly and accurately determined according to each module of the escape route determination system. This method can be executed by an escape route determination device for a utility tunnel. The escape route determination device for a utility tunnel can be implemented in the form of hardware and / or software, and the escape route determination device for a utility tunnel can be configured in an electronic device such as a mobile phone, a computer, or a server. As Figure 1 shown, the method includes:

[0032] S110. When the network service providing module receives the device access information of the device to be positioned, determine the device position information of the device to be positioned, and send the device position information to the device positioning module.

[0033] Among them, the device position information is the two-dimensional coordinate information of the device to be positioned in the preset two-dimensional coordinate system corresponding to the target utility tunnel, and the target utility tunnel is a utility tunnel without deploying equipment related to the geographic information system.

[0034] The technical solution provided by the embodiment of the present invention is applied to an escape route determination system, which includes: a network service providing module, a device positioning module, and a route determination module. Among them, the network service providing module is used to provide network services for the target utility tunnel. The network service providing module is determined by multiple wireless access devices deployed in the target utility tunnel according to a triangular network topology structure. Each wireless access device is used to provide network services within a preset range. The device positioning module is used to determine the three-dimensional coordinate information of the device to be positioned in the target utility tunnel. The route determination module is used to determine the escape route corresponding to the device to be positioned. The network service providing module is communicatively connected to the device positioning module, and the device positioning module is communicatively connected to the route determination module.

[0035] A utility tunnel is an underground urban pipeline comprehensive corridor formed by integrating various urban engineering pipelines such as electricity, communication, gas, heating, and water supply and drainage. The target utility tunnel can be a utility tunnel deployed with multiple wireless access devices and without devices related to the geographic information system. It should be noted that devices related to the Geographic Information System (GIS) can be understood as GIS devices.

[0036] The device to be positioned can be understood as the device held by a person in the target utility tunnel. For example, the device to be positioned can be a mobile phone or other mobile terminal devices. Before the device to be positioned uses the network services provided by the network service providing module, it can first send device access information to the network service providing module. It can be understood that the device access information is the request information for the device to be positioned to request the network services provided by the network service module. The device location information can be used to represent the position coordinates of the device to be positioned in the target utility tunnel. In order to accurately determine the device location information of the device to be positioned, a two-dimensional coordinate system corresponding to the target utility tunnel can be constructed according to a preset origin, that is, a preset two-dimensional coordinate system. Under the preset two-dimensional coordinate system, each position in the target utility tunnel has its corresponding two-dimensional coordinate information. The device location information is the two-dimensional coordinate information of the device to be positioned under the preset two-dimensional coordinate system corresponding to the target utility tunnel.

[0037] Specifically, since the utility tunnel is usually an underground environment without network, in order to accurately determine the location of the device to be located, multiple wireless access devices can be deployed in the target utility tunnel according to the triangular network topology structure, so as to provide network services for the target utility tunnel based on the network service providing modules determined by the multiple wireless access devices. It should be noted that, in order to save costs, the target utility tunnel may not be equipped with devices related to the geographic information system, and the positioning process of the device to be located can be achieved through the wireless access devices. That is, when the network service providing module of the escape route determination system receives the device access information sent by the device to be located, according to the device access information of the device to be located and the device coordinate information of the multiple wireless access devices that receive the device access information in the preset two-dimensional coordinate system, the device location information of the device to be located in the preset two-dimensional coordinate system can be determined, and the device location information is sent to the device positioning module communicatively connected to the network service providing module to determine the more accurate three-dimensional coordinate information of the device to be located.

[0038] In the embodiment of the present invention, the method for determining the device location information may be: taking the wireless access device that receives the device access information in the network service providing module as the target access device, and determining the distance information between each target access device in the network service providing module and the device to be located according to the first moment when the device to be located sends the device access information, the second moment when the target access device receives the device access information, and the preset sending speed of the device access information; determining the device location information of the device to be located according to the distance information corresponding to the multiple target access devices in the network service providing module and the device coordinate information of the target access device in the preset two-dimensional coordinate system.

[0039] Among them, since each wireless access device can provide network services within a preset range, there are multiple wireless access devices in the network service providing module that receive the device access information. The wireless access device that receives the device access information of the device to be located can be taken as the target access device. The first moment can be understood as the moment when the device to be located sends the device access information. The second moment can be understood as the moment when the target access device receives the device access information. The preset sending speed can be understood as the transmission speed of the device access information from the device to be located to the target access device. The distance information can be understood as the distance between the device to be located and the target access device. It should be noted that distance information corresponds to each target access device. The device coordinate information can be used to represent the position information of the target access device in the preset two-dimensional coordinate system.

[0040] Specifically, the wireless access device that receives the device access information in the network service providing module is used as the target access device. Since the wireless access device can provide network services within a preset range, there are multiple wireless access devices in the network service providing module that receive the device access information. For multiple target access devices, the distance information between the current target access device and the device to be located can be determined according to the first moment when the device to be located sends the device access information, the second moment when the current target access device receives the device access information, and the preset sending speed of the device access information. According to the multiple distance information between the multiple target access devices and the device to be located, and the device coordinate information of each target access device in the preset two-dimensional coordinate system, the device position information of the device to be located is determined by using methods such as trigonometric functions.

[0041] Exemplarily, refer to Figure 2 , Figure 2 which is a flowchart example of the escape route determination method. Figure 2 The underground AP network service in corresponds to the network service provided by the network service providing module mentioned in the embodiments of the present invention. The Web service platform corresponds to the device positioning module mentioned in the embodiments of the present invention, and the escape route algorithm service corresponds to the route determination module mentioned in the embodiments of the present invention. Arrange multiple wireless access point (AP) devices in a triangular topology structure to build an AP network in the target utility tunnel to provide AP network services. It should be noted that the AP device corresponds to the wireless access device mentioned in the above embodiments. The positioning process of the device to be located is realized through the underground AP network service, that is Figure 2 the first step in , the APP positioning service. The specific method can be: when the device to be located sends the device access information to the AP device based on the corresponding application (APP), correspondingly, the AP device will receive the device access information. The AP device that receives the device access information is used as the target AP device, that is, the target access device mentioned above. In the AP network, the device to be located may be located inside the triangle corresponding to at least three target AP devices. According to the device coordinate information of at least three target AP devices in the preset two-dimensional coordinate system, the distance between any two of the at least three target AP devices can be determined. The distance information between the device to be located and the target AP device is determined. According to the distance information between the device to be located and the target AP device, the distance between any two of the at least three target AP devices, and the device coordinate information of the at least three target AP devices in the preset two-dimensional coordinate system, the internal position of the device to be located in the triangle corresponding to the at least three target AP devices is determined, so as to determine the device position information of the device to be located.

[0042] S120. When the device positioning module receives the device location information, based on the position mapping algorithm, the device location information, and the height information of the target utility tunnel, determine the three-dimensional coordinate information corresponding to the device location information, and send the three-dimensional coordinate information to the route determination module.

[0043] Among them, the position mapping algorithm can be pre-set and is used to convert the device location information into three-dimensional coordinate information. The height information of the target utility tunnel can be the tunnel height information corresponding to the position of the device to be located in the target utility tunnel. It should be noted that the heights at different positions of the target utility tunnel may be inconsistent. Therefore, in order to accurately determine the three-dimensional coordinate information of the device to be located, the height information of the target utility tunnel corresponding to the device location information of the device to be located can be determined. Optionally, the height information of the target utility tunnel at the location where the device to be located is located can be retrieved from the corresponding database. The three-dimensional coordinate information can be understood as the three-dimensional coordinates of the device to be located. The route determination module can be used to determine the escape route corresponding to the device to be located according to the three-dimensional coordinate information of the device to be located.

[0044] Specifically, when the device positioning module receives the device location information sent by the network service providing module, it can convert the device location information of the device to be located into three-dimensional coordinate information according to the position mapping algorithm in combination with the height information of the target utility tunnel corresponding to the device location information of the device to be located. Among them, the abscissa information in the three-dimensional coordinate information represents the longitude information of the device to be located, and the ordinate in the three-dimensional coordinate information represents the latitude information of the device to be located. Send the three-dimensional coordinate information to the route determination module so that the route determination module can determine the escape route corresponding to the device to be located.

[0045] In the embodiment of the present invention, the determination method of the three-dimensional coordinate information can be: perform a mapping process on the device location information according to the position mapping algorithm to determine the device longitude and latitude information corresponding to the device location information; determine the three-dimensional coordinate information of the device to be located according to the height information of the target utility tunnel and the device longitude and latitude information.

[0046] Among them, the device longitude and latitude information is understood as the longitude information and latitude information corresponding to the device location information. After the abscissa information in the device location information is subjected to a mapping process, the longitude information in the device longitude and latitude information can be obtained. After the ordinate information in the device location information is subjected to a mapping process, the latitude information in the device longitude and latitude information can be obtained.

[0047] Specifically, perform a mapping process on the device location information according to the position mapping algorithm to obtain the device longitude and latitude information corresponding to the device to be located. Perform a mapping process on the height information of the target utility tunnel using the position mapping algorithm, and combine it with the device longitude and latitude information to obtain the three-dimensional coordinate information of the device to be located.

[0048] Exemplarily, in combination with the above example, refer to Figure 2 , the position mapping algorithm can be a virtual positioning and GIS positioning mapping algorithm, which is used to convert the device position information corresponding to the preset two-dimensional coordinate system, that is, virtual positioning, into three-dimensional coordinate information. That is, when the web service platform receives the device position information of the device to be located, through the virtual positioning and GIS positioning mapping algorithm, the device position information is scaled by a preset ratio to obtain the device longitude and latitude information corresponding to the longitude and latitude information. Correspondingly, the height information is scaled proportionally to obtain the adjusted height information. According to the device longitude and latitude information and the adjusted height information, the three-dimensional coordinate information of the device to be located is obtained, so as to process the three-dimensional coordinate information based on the escape route algorithm service to determine the escape route of the device to be located.

[0049] S130. When the route determination module detects a disaster point in the target utility tunnel, determine the location information of the disaster point in the target utility tunnel, and determine the target escape route according to the exit location information, three-dimensional coordinate information, and disaster point location information of at least one target escape exit, and feedback the target escape route to the device to be located.

[0050] Among them, the target escape exit is an escape exit in an open state. The disaster point can be understood as a dangerous position in the target utility tunnel. Optionally, when detecting the target utility tunnel, it can be detected from multiple dimensions such as temperature and humidity and / or toxic gas and / or pipeline pressure to determine whether there is a disaster point in the target utility tunnel. For example, when the temperature at a certain position in the target utility tunnel exceeds a preset value, this position can be used as the disaster point in the target utility tunnel. The disaster point location information can be understood as the three-dimensional coordinate information corresponding to the disaster point. There are multiple escape exits in the target utility tunnel, but the escape exits may be in a closed state or an unopenable state, so the state of the escape exits can be detected to determine the escape exits in an open state. The escape exits in an open state can be used as the target escape exits. Optionally, the escape exits that are currently in a closed state but can be normally opened can also be used as the target escape exits. The target escape route can be the optimal escape route, that is, the route that the person holding the device to be located can escape from the target utility tunnel fastest.

[0051] Specifically, the route determination module detects the target utility tunnel in real time from multiple dimensions such as temperature and humidity, and / or toxic gas, and / or pipeline pressure. When the value corresponding to a certain position in the target utility tunnel in a certain dimension exceeds the preset value, that position is taken as the disaster point, and the three-dimensional coordinate information corresponding to that position is taken as the disaster point position information. When a disaster point is detected in the target utility tunnel, each escape exit of the target utility tunnel is detected to determine the escape exits that are in an open state or can be in an open state, and these escape exits are taken as the target escape exits. The three-dimensional coordinate information of at least one target escape exit, that is, the exit position information, is determined. According to the exit position information of at least one target escape exit, the three-dimensional coordinate information of the device to be located, and the disaster point position information, the target escape route corresponding to the device to be located is determined, and the target escape route is fed back to the device to be located. Optionally, the route determination module can feed back the target escape route to the device positioning module, so that the device positioning module feeds back the target escape route to the device to be located or displays it on the display interface corresponding to the device positioning module.

[0052] It should be noted that each module of the escape route determination system can process multiple devices to be located simultaneously and feed back the corresponding target escape routes to the corresponding devices to be located.

[0053] Exemplarily, in combination with the above example, refer to Figure 2 , the web service platform sends the three-dimensional coordinate information of the device to be located to the escape route algorithm service, so that when the escape route algorithm service detects a disaster point in the target utility tunnel, according to the disaster point position information, the exit position information of at least one target escape exit that is in an open state or can be in an open state, and the three-dimensional coordinate information of the device to be located, the target escape route corresponding to the device to be located is determined. The escape route algorithm service can feed back the target escape route and the exit position information of the corresponding target escape exit to the web service platform, so that the web service platform feeds back the target escape route to the device to be located through the information service of the corresponding application program, so that the device to be located can obtain the target escape route.

[0054] Optionally, the method further includes: displaying the three-dimensional coordinate information of at least one device to be located, the disaster point position information, the exit position information of at least one target escape exit, and the target escape route on the display interface of the device positioning module.

[0055] Among them, the display interface can be an interface for displaying the three-dimensional coordinate information of at least one device to be located, the location information of the disaster points of the target utility tunnel, the location information of at least one target emergency exit, and the target emergency escape route. Through the content displayed on the display interface, the corresponding staff can clearly understand the internal situation in the target utility tunnel, thus ensuring the safety of the personnel in the target utility tunnel.

[0056] Specifically, since each module of the escape route determination system can process at least one device to be located, the route determination module of the escape route determination system can determine the target escape route corresponding to each device to be located. Then, the route determination module can send the target escape routes of at least one device to be located to the device positioning module. The three-dimensional coordinate information of at least one device to be located, the location information of the disaster points of the target utility tunnel, the location information of at least one target emergency exit, and the target escape routes of at least one device to be located are displayed on the display interface of the device positioning module.

[0057] Exemplarily, in combination with the above example, refer to Figure 2 , taking the display interface as a browser interface as an example for illustration. Through the escape route algorithm service, the target escape routes of at least one device to be located can be determined and fed back to the web service platform, so as to display the three-dimensional coordinate information of each device to be located, the location information of the disaster points of the target utility tunnel, the location information of at least one target emergency exit, and the target escape route through the browser interface of the web service platform.

[0058] The technical solution of this embodiment is applied to an escape route determination system, which includes a network service providing module, a device positioning module, and a route determination module. The network service providing module is used to provide network services for the target utility tunnel. The network service providing module is determined by multiple wireless access devices deployed in the target utility tunnel according to a triangular network topology structure. Each wireless access device is used to provide network services within a preset range. The network service providing module is communicatively connected to the device positioning module, and the device positioning module is communicatively connected to the route determination module. When the network service providing module receives the device access information of the device to be positioned, it determines the device position information of the device to be positioned and sends the device position information to the device positioning module. Among them, the device position information is the two-dimensional coordinate information of the device to be positioned in the preset two-dimensional coordinate system corresponding to the target utility tunnel, and the target utility tunnel is a utility tunnel without devices related to the geographic information system. Based on this, it is possible to accurately determine the device position information of the device to be positioned without deploying devices related to the geographic information system for the target utility tunnel, providing data support for subsequent determination of the three-dimensional coordinate information of the device to be positioned. When the device positioning module receives the device position information, it determines the three-dimensional coordinate information corresponding to the device position information based on the position mapping algorithm, the device position information, and the height information of the target utility tunnel, and sends the three-dimensional coordinate information to the route determination module. When the route determination module detects a disaster point in the target utility tunnel, it determines the disaster point position information of the target utility tunnel, and determines the target escape route according to the exit position information, three-dimensional coordinate information, and disaster point position information of at least one target escape exit, and feeds back the target escape route to the device to be positioned, so that the person holding the device to be positioned can quickly escape from the target utility tunnel according to the target escape route. The present invention solves the problem of untimely escape caused by relying on the memory of staff in the prior art.

[0060] Figure 3 It is a flowchart of an escape route determination method for a utility tunnel provided by Embodiment 2 of the present invention. This embodiment of the present invention is a refinement of the step of "determining the target escape route according to the exit position information, three-dimensional coordinate information, and disaster point position information of at least one target escape exit" on the basis of the above embodiment. The specific implementation manner can refer to the technical solution of this embodiment. Among them, the same or corresponding technical terms as those in the above embodiment will not be elaborated here. As Figure 3 shown, the method includes:

[0061] S210. When the network service providing module receives the device access information of the device to be located, determine the device location information of the device to be located, and send the device location information to the device positioning module.

[0062] Wherein, the device location information is the two-dimensional coordinate information of the device to be located in the preset two-dimensional coordinate system corresponding to the target integrated pipe gallery, and the target integrated pipe gallery is an integrated pipe gallery without devices related to the geographic information system deployed.

[0063] S220. When the device positioning module receives the device location information, based on the position mapping algorithm, the device location information, and the height information of the target integrated pipe gallery, determine the three-dimensional coordinate information corresponding to the device location information, and send the three-dimensional coordinate information to the route determination module.

[0064] S230. When the route determination module detects a disaster point in the target integrated pipe gallery, determine the disaster point location information of the target integrated pipe gallery, and determine the matrix information corresponding to the target integrated pipe gallery according to the exit location information of at least one target escape exit, the three-dimensional coordinate information, and the disaster point location information.

[0065] Wherein, the matrix information can be used to characterize the positional relationship between the exit location information, the three-dimensional coordinate information, and the disaster point location information.

[0066] Specifically, the route determination module detects the target integrated pipe gallery in real time from multiple dimensions such as temperature and humidity and / or toxic gas and / or pipeline pressure, so that when the value corresponding to a certain position in the target integrated pipe gallery in a certain dimension exceeds the preset value, that position is used as the disaster point, and the three-dimensional coordinate information corresponding to that position is used as the disaster point location information. According to the exit location information of at least one target escape exit, the three-dimensional coordinate information, and the disaster point location information, determine the relative positional relationship between the exit location information, the three-dimensional coordinate information, and the disaster point location information. Based on the relative positional relationship, initialize the exit location information, the three-dimensional coordinate information, and the disaster point location information into an adjacency matrix to obtain the matrix information corresponding to the target integrated pipe gallery.

[0067] Exemplarily, according to the path planning diagram corresponding to the target integrated pipe gallery, determine the relative positional relationship between the exit location information of at least one target escape exit, the three-dimensional coordinate information of the device to be located, and the disaster point location information. Based on the relative positional relationship, initialize the exit location information, the three-dimensional coordinate information, and the disaster point location information into an adjacency matrix to generate an unweighted undirected graph data structure. It should be noted that since the exit location information, the three-dimensional coordinate information of the device to be located, and the disaster point location information are all three-dimensional coordinate information, therefore, the obtained adjacency matrix has one more adjacency matrix representing height information compared to the adjacency matrix corresponding to the two-dimensional coordinate information.

[0068] S240. Process the matrix information based on the shortest path determination algorithm to determine at least one shortest path information corresponding to the device to be located.

[0069] Among them, the shortest path determination algorithm can be used to determine the shortest path between the three-dimensional coordinate information of the device to be located and the exit position information of at least one target escape exit. Since there is at least one target escape exit in the target utility tunnel, there may be at least one shortest path information between the target escape exit and the device to be located. The shortest path information can be used to represent the shortest path between the target escape exit and the device to be located.

[0070] Specifically, process the matrix information through the shortest path determination algorithm to determine at least one shortest path information between at least one target escape exit and the device to be located, so as to determine the target escape route corresponding to the device to be located through the at least one shortest path information.

[0071] Exemplarily, in combination with the above example, the shortest path determination algorithm is the Dijkstra algorithm for illustration. Generate an unweighted undirected graph according to the matrix information corresponding to the target utility tunnel, and determine the shortest path between the vertex corresponding to the device to be located and the vertex corresponding to the target exit position in the unweighted undirected graph through the Dijkstra algorithm to obtain at least one shortest path information.

[0072] S250. Determine the target escape route according to at least one shortest path information, and feedback the target escape route to the device to be located.

[0073] Specifically, evaluate at least one shortest path information to determine the target escape route from at least one shortest path information, and send the target escape route to the device positioning module so that the device positioning module feeds it back to the device to be located.

[0074] In the embodiment of the present invention, the shortest path information includes at least one section information. The method for determining the target escape route according to the shortest path information may be: determine the path evaluation attribute corresponding to each shortest path information according to the preset weight coefficient corresponding to at least one section information in each shortest path information; determine the shortest path information corresponding to the maximum path evaluation attribute as the optimal path information, and determine the target escape route based on the optimal path information.

[0075] Among them, for at least one shortest path information between the target escape exit and the device to be located, each shortest path information may include at least one section information. The preset weight coefficient can be used to characterize the difficulty of passing through each section information. The path evaluation attribute can be obtained by summing up the preset weight coefficients corresponding to all section information in the shortest path information. The path evaluation attribute can be used to characterize the difficulty of passing through the shortest path information. The optimal path information can be the shortest path information corresponding to the maximum path evaluation attribute.

[0076] Specifically, for at least one shortest path information between the target escape exit and the device to be located, perform a summation process on the preset weight coefficients of at least one section information corresponding to the current shortest path information to obtain the path evaluation attribute corresponding to the current shortest path information. From the path evaluation attributes corresponding to at least one shortest path information, determine the maximum path evaluation attribute, and use the shortest path information corresponding to the maximum path evaluation attribute as the optimal path information. Determine the path corresponding to the optimal path information as the target escape route.

[0077] Optionally, when a disaster point is detected in the target escape route, update the location information of the disaster point, and generate a warning prompt message based on the updated location information of the disaster point and the three-dimensional coordinate information of the device to be located; determine an alternative escape route according to the updated location information of the disaster point and the path evaluation attribute of at least one shortest path information corresponding to the device to be located; feedback the alternative escape route and the warning prompt message to the device to be located.

[0078] Among them, the warning prompt message can be used to prompt the person holding the device to be located of the updated location information of the disaster point. The alternative escape route can be selected from at least one shortest path information, and it is the optimal path that avoids the updated location information of the disaster point.

[0079] Specifically, when escaping from the target utility tunnel according to the target escape route, new disaster points may be added to the target escape route. Therefore, the target escape route can be detected in real time to update the location information of the disaster point when a disaster point is detected in the target escape route. Generate a warning prompt message according to the updated location information of the disaster point and the three-dimensional coordinate information where the device to be located is currently located, so as to remind the person holding the device to be located of the warning distance information between the current position and the updated location information of the disaster point based on the warning prompt message. According to the updated location information of the disaster point and the path evaluation attribute of at least one shortest path information corresponding to the device to be located, determine the shortest path information that does not include the updated location information of the disaster point and has the largest path evaluation attribute, that is, determine the alternative escape route. Feedback the alternative escape route and the warning prompt message to the device to be located, so that the person holding the device to be located can escape from the target utility tunnel according to the alternative escape route.

[0080] The technical solution of this embodiment is applied to an escape route determination system, which includes: a network service providing module, a device positioning module, and a route determination module. The network service providing module is used to provide network services for the target utility tunnel. The network service providing module is determined by multiple wireless access devices deployed in the target utility tunnel according to a triangular network topology structure. Each wireless access device is used to provide network services within a preset range. The network service providing module is communicatively connected to the device positioning module, and the device positioning module is communicatively connected to the route determination module. When the network service providing module receives the device access information of the device to be positioned, it determines the device position information of the device to be positioned and sends the device position information to the device positioning module. Wherein, the device position information is the two-dimensional coordinate information of the device to be positioned in the preset two-dimensional coordinate system corresponding to the target utility tunnel, and the target utility tunnel is a utility tunnel without devices related to the geographic information system. Based on this, it is possible to accurately determine the device position information of the device to be positioned without deploying devices related to the geographic information system for the target utility tunnel, providing data support for subsequent determination of the three-dimensional coordinate information of the device to be positioned. When the device positioning module receives the device position information, it determines the three-dimensional coordinate information corresponding to the device position information based on the position mapping algorithm, the device position information, and the height information of the target utility tunnel, and sends the three-dimensional coordinate information to the route determination module. When the route determination module detects a disaster point in the target utility tunnel, it determines the disaster point position information of the target utility tunnel, and determines the matrix information corresponding to the target utility tunnel according to the exit position information of at least one target escape exit, the three-dimensional coordinate information, and the disaster point position information. Based on the shortest path determination algorithm, the matrix information is processed to determine at least one shortest path information corresponding to the device to be positioned. According to at least one shortest path information, the target escape route is determined and fed back to the device to be positioned, so that the person holding the device to be positioned can quickly escape from the target utility tunnel according to the target escape route. The present invention solves the problem of untimely escape caused by relying on the memory of staff in the prior art. Through the various modules of the escape route determination system, it is possible to quickly and accurately determine the target escape route without deploying devices related to the geographic information system for the target utility tunnel, saving the operation cost of the target utility tunnel and ensuring the safety of the personnel in the target utility tunnel.
