However, it should be noted that the method and the device for processing environmental monitoring data provided in the embodiments of the present application are not limited to fire monitoring in forest scenes, but may be applied to other scenes where danger may occur, which is not limited in the embodiments of the present application.

The following describes a specific implementation manner of the environmental monitoring data processing method applied to the UPF network element with reference to the embodiments and the accompanying drawings.

Referring to fig. 3, a first flowchart of a method for processing environmental monitoring data according to an embodiment of the present application is shown in fig. 3, where the method may include:

s101: and acquiring a monitoring data packet uploaded by the environment monitoring equipment preset in the environment to be monitored through the user plane tunnel.

In this embodiment, an environmental monitoring device is set in an environment to be monitored, where the environmental monitoring device may be set at least one position in the environment to be monitored according to a monitoring requirement, and in general, in order to ensure safety of the environment to be monitored, a plurality of environmental monitoring devices may be set according to a monitoring range of the environmental monitoring device and an area of the environment to be monitored.

The type of the environmental monitoring device may be determined according to the monitoring requirements for the environment to be monitored, for example, in fire monitoring, the environmental monitoring device may be a device integrated with sensors such as a vision sensor, a smoke sensor, a temperature sensor, etc., and may further include various types of sensors such as a photosensitive sensor, a sound sensor, a gas sensor, a chemical sensor, etc. The visual sensor can generate a detection image of the environment to be monitored by capturing thousands of pixels in light, the smoke sensor can capture the smoke concentration in the environment to be monitored, and the gas sensor can capture the concentration of carbon monoxide, carbon dioxide and other gases in the environment to be monitored.

The environment monitoring equipment is accessed to a 5G core network through a wireless access network, performs data transmission through a user plane tunnel established with a UPF network element in the 5G core network, monitors the environment to be monitored, acquires environment monitoring data, encodes the environment monitoring data according to a tunnel protocol of the user plane tunnel to generate a monitoring data packet, and then sends the monitoring data packet to the UPF network element through the user plane tunnel. When the environment monitoring data is encoded to generate a monitoring data packet, the packet head of the monitoring data packet carries identification information, and the identification information is used for indicating the type of the environment monitoring data in the monitoring data packet.

For example, the user plane tunnel is a GTP tunnel based on the GPRS tunneling protocol (GPRS Tunneling Protocol), and the environment monitoring device generates the monitoring data packet by GTP encoding the environment monitoring data.

In some embodiments, in the process of performing fire monitoring on an environment to be monitored by the environment monitoring equipment, if no fire source appears in the environment to be monitored, the environment monitoring equipment normally performs monitoring work, and when the fire source appears in the monitoring range of the environment monitoring equipment, a gas sensor in the environment monitoring equipment triggers to determine the basic position of the fire source and acquire the concentration of sensitive gas; acquiring a monitoring environment image according to a visual sensor, analyzing the monitoring environment image by environment monitoring equipment, and determining the distance between a fire source and the environment monitoring equipment, the ignition area, the material quality of objects around the fire source and the propagation speed of the fire; acquiring the smoke concentration of the environment to be monitored according to a smoke sensor; according to a photosensitive sensor and a thermal imager in the environment monitoring equipment, thermal imaging data of the environment to be monitored are obtained, and the basic position of a fire source, the distance between the fire source and the environment monitoring equipment, the ignition area, the material quality of objects around the fire source, the propagation speed of the fire, the concentration of sensitive gas, the concentration of smoke and the thermal imaging data are encoded to generate a monitoring data packet.

S102: and decoding the monitoring data packet to obtain environment monitoring data and sign information.

In this embodiment, after receiving a monitoring data packet sent by an environmental monitoring device, the UPF network element decodes the monitoring data packet according to a tunnel protocol of a user plane tunnel to obtain environmental monitoring data and flag information, and the UPF network element determines whether the environmental monitoring data is alarm data according to the flag information. For example, the UPF network element may perform GTP decoding on the monitoring data packet to obtain the environmental monitoring data and the flag information.

In some embodiments, since the UPF network element may establish a user plane tunnel with multiple types of UEs and receive various data reported by the multiple types of UEs, in order to determine alarm data from the data reported by the multiple types of UEs, it is necessary to perform a judgment according to the flag information in the monitoring data packet.

S103: if the flag information is a preset alarm flag, the environment monitoring data is sent to the data center, and the data center generates an alarm processing scheme according to the position information of the environment monitoring equipment, the environment monitoring data and the map information of the environment to be monitored under the condition that the environment monitoring data is the alarm data.

In this embodiment, after the UPF network element analyzes the flag information from the monitoring data packet, it determines whether the value of the flag information indicates that the flag information is a preset alarm flag, and if the value of the flag information indicates that the flag information is the preset alarm flag, it determines that the environmental monitoring data is alarm data, and reports the environmental monitoring data to the data center.

The data center determines the position information of the environment monitoring equipment from the environment monitoring equipment management library according to the identification information of the environment monitoring equipment in the environment monitoring data, and performs data analysis according to the environment monitoring data, the position information of the environment monitoring equipment, the map information of the environment to be monitored, the weather condition, the air humidity, the wind speed, the wind direction and the road condition to generate an alarm processing scheme. The alarm processing scheme may include: rescue routes, rescue protocols, and the like.

After the data center generates the alarm processing scheme, the alarm processing scheme and the environment monitoring data are sent to the fire control center for the fire control center to refer to for rescue.

According to the environment monitoring data processing method provided by the embodiment, the environment to be monitored is monitored by using the environment monitoring equipment, the monitoring data packet is uploaded to the UPF network element in the core network through the user plane tunnel, and the UPF network element reports the environment monitoring data to the data center when determining that the environment monitoring data is alarm data, so that the data center generates an alarm processing scheme according to the environment monitoring data. By utilizing the technical advantages of ultra-high speed, ultra-low delay and ultra-large connection of a core network, environment monitoring data acquired by environment monitoring equipment in an environment to be monitored are reported to a data center, environment real-time monitoring and timely data reporting are realized, and the real reliability of the data is ensured, so that the data center can perform accurate data analysis, favorable data support is provided for rescue workers, the safety of the rescue workers can be ensured, timely rescue can be realized, and the life and property safety of the masses is ensured.

In one possible implementation, the method may further include:

sending first notification information to the SMF network element, wherein the first notification information comprises: the identification information of the environmental monitoring device is used for enabling the SMF network element to determine the position information of the environmental monitoring device according to the identification information of the environmental monitoring device, and second notification information is sent to the data center, wherein the second notification information comprises: location information of the environmental monitoring device.

In this embodiment, when the environmental monitoring device registers in the core network, the environmental monitoring device will report its own location information to the core network, and the SMF network element will manage the location information of the environmental monitoring device. After the UPF network element determines that the mark information is a preset alarm mark, sending first notification information to the SMF network element, and informing the SMF network element that the environment monitoring data reported by the environment monitoring equipment is alarm data, wherein the first notification information carries the identification information of the environment monitoring equipment.

After the SMF network element receives the first notification information, the location information of the environment monitoring equipment is determined according to the identification information of the environment monitoring equipment, and the location information of the environment monitoring equipment is sent to the data center through the NEF network element.

In one possible implementation, the second notification information further includes: the data center is used for determining that the environment monitoring data is alarm data under the condition that the preset alarm mark is received.

In this embodiment, if the data center receives various types of data sent from the UPF network element and other channels, the data center cannot determine that the environmental monitoring data is alarm data in the received environmental monitoring data, so that the data center needs to be informed that the environmental monitoring data is alarm data.

The method comprises the steps that a cell of a preset alarm mark is configured in an SMF (surface management function) network element in advance, after the SMF network element receives first notification information sent by a UPF network element and determines that the UPF network element receives alarm data sent by environment monitoring equipment, the SMF network element carries the cell of the preset alarm mark in second notification information sent by a data center, the second notification information sent by the SMF network element and the environment monitoring data reported by the UPF network element take identification information of the environment monitoring equipment as matching marks, and the data center determines that the environment monitoring data is alarm data after determining that the environment monitoring data, the position information and the preset alarm mark corresponding to the environment monitoring equipment are received.

For example, in Fire monitoring, a Fire alarm cell is configured in an SMF network element, and if the identification information of the Fire alarm cell, that is, a flag bit is 1, the environmental monitoring data is determined to be alarm data.

According to the environment monitoring data processing method provided by the embodiment, the cell of the preset alarm mark is configured in the SMF network element, so that the SMF network element can inform the data center that the received environment monitoring data is the alarm data, an alarm processing scheme is timely generated according to the environment monitoring data, and timely rescue is guaranteed.

In one possible implementation manner, if the user plane tunnel is in an idle state, before the monitoring data packet uploaded by the environmental monitoring device through the user plane tunnel, which is preset in the environment to be monitored, is obtained in S101, the method may further include:

receiving a tunnel recovery notification sent by an AMF network element, wherein the tunnel recovery notification comprises: the method comprises the steps that an AMF network element sends an interface identifier and a UPF tunnel identifier of a UPF network element to a base station to which the environment monitoring equipment belongs, so that the environment monitoring equipment and the UPF network element recover the bearing of a user plane tunnel based on the identifier of the base station to which the environment monitoring equipment belongs, the base station tunnel identifier, the interface identifier and the UPF tunnel identifier of the UPF network element.

Generally, after registering to a core network and establishing a user plane tunnel with the core network, when no fire source exists in the environment to be monitored, the environment monitoring device does not need to report the environment monitoring device, in this case, if the user plane tunnel keeps a link state all the time, resources of the core network are wasted, so in general, the user plane tunnel between the environment monitoring device and the core network is in a broken link state when data transmission is not performed, and is only recovered when the data transmission is required.

In this embodiment, when the environment monitoring device monitors a fire source in the environment to be monitored, a service request is initiated to an AMF network element in the core network, the core network is notified that the environment monitoring device needs to report environment monitoring data, after the AMF network element receives the service request, an interface identifier and a UPF tunnel identifier of the UPF network element are sent to a base station to which the environment monitoring device belongs, the base station to which the environment monitoring device belongs sends the base station identifier and the base station tunnel identifier to the UPF network element through the AMF network element, and the base station to which the UPF network element and the environment monitoring device belong restores the load of the user plane tunnel according to the base station identifier, the base station tunnel identifier, the interface identifier of the UPF network element and the UPF tunnel identifier, so that the environment monitoring device performs data transmission with the UPF network element through the user plane tunnel by the base station to which the environment monitoring device belongs.

S17: the SMF network element sends the second notification information to the data center through the NEF network element.

S18: the UPF network element sends the environment monitoring data to the data center.

In another possible implementation, before the environment monitoring device reports the environment monitoring data to the data center through the core network, the environment monitoring device first needs to establish a user plane tunnel with the core network.

Referring to fig. 5, a second flowchart of the environmental monitoring data processing method provided in the embodiment of the present application is shown in fig. 5, and before the monitoring data packet uploaded by the environmental monitoring device preset in the environment to be monitored through the user plane tunnel is obtained in S101, the method may further include:
