[0042] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0043] At present, at the power emergency site, the deployment of data access points is divided into four modes: individual soldier, vehicle-mounted, mobile deployment and fixed deployment. Individual soldier deployment mainly refers to portable communication and monitoring equipment provided for individual soldiers or law enforcement personnel. Vehicle-mounted deployment is to install the data access point on the vehicle, and realize dynamic access and transmission of data through the mobility of the vehicle. Mobile deployment refers to the use of movable equipment to realize data access and transmission. Fixed deployment is to install the data access point in a fixed location and access the network through wired or wireless means.

[0044] In the power emergency repair scenario, the relevant equipment at the emergency rescue site communicates with the relevant data network by accessing the data access terminal (including individual terminals, vehicle-mounted terminals, mobile terminals and fixed terminals). However, the existing heterogeneous network access method is difficult to meet the requirements of improving the efficiency and access performance of the access equipment to be accessed (i.e. the relevant equipment at the emergency rescue site) in the power emergency repair scenario.

[0045] Based on this, in order to improve the efficiency and access performance of the access equipment to the data access terminal in the power emergency repair scenario, the present invention provides a heterogeneous network access method and system, and an edge computing device.

[0046] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings.

[0047] Figure 1 1 is a flow chart of a heterogeneous network access method provided by an embodiment of the present invention. The heterogeneous network access method is applied to an edge computing device. Figure 1 As shown, this process includes:

[0048] Step 101: Determine the location and required bandwidth of each data access terminal; the data access terminal includes a single-soldier terminal, a vehicle-mounted terminal, a mobile terminal and a fixed terminal.

[0049] Specifically, individual terminals, vehicle-mounted terminals, mobile terminals and fixed terminals are deployed at the power emergency site. Fixed terminals are mainly used for data relay. Vehicle-mounted terminals and edge computing devices can be deployed on repair vehicles as temporary command carriers for emergency repair teams. Individual terminals are carried by relevant personnel. Mobile terminals support broadband data transmission and can be used to access various devices, such as cameras, to achieve data transmission and sharing.

[0050] A single-soldier terminal may be provided with a positioning module (such as a Beidou positioning module), a WIFI module, a Bluetooth module, a wireless receiving module, and a wireless transmitting module. A vehicle-mounted terminal, a mobile terminal, and a fixed terminal may be provided with a positioning module (such as a Beidou positioning module), a WIFI module, a Bluetooth module, a LoRa (Long Range Radio) module, a wireless receiving module, and a wireless transmitting module.

[0051] The edge computing device can read the location information collected by the positioning module in the data access terminal connected to it, and determine the location of the corresponding data access terminal according to the location information. In addition, the edge computing device can also read the data information in the wireless transmission module of the data access terminal connected to it, determine the nature of the data to be accessed by the corresponding data access terminal according to the data information, and calculate the required bandwidth of the corresponding data access terminal according to the nature of the data to be accessed, wherein the nature of the data to be accessed includes the environmental information and network status of the corresponding data access terminal.

[0052] Step 102: Construct a bandwidth demand spatial distribution map based on the location and required bandwidth.

[0053] Specifically, at the power emergency repair site, the data transmission requirements of different locations and different data access terminals may be different. Therefore, by drawing a spatial distribution map of bandwidth requirements, we can intuitively understand the bandwidth requirements of each area and each data access terminal, so as to carry out more reasonable network planning and resource allocation.

[0054] Step 103: Determine the target locations of individual terminals, vehicle-mounted terminals, and mobile terminals according to the bandwidth demand spatial distribution map.

[0055] Specifically, the whale algorithm can be used to reduce the overlapping area of ​​network coverage at the power emergency repair site and balance the access performance of the entire network. According to the bandwidth demand spatial distribution map, the target positions of individual terminals, vehicle terminals and mobile terminals can be determined. This can avoid the data transmission bottleneck caused by excessive local access data and ensure the best network planning effect.

[0056] Step 104: Determine the target data access terminal of each device to be accessed according to the locations of all target locations and fixed terminals.

[0057] Specifically, a multi-layer game algorithm can be used to determine the target data access terminal of each device to be accessed according to the locations of all target locations and fixed terminals. In the actual implementation process, the target data access terminal can be determined in combination with the unique identification information of the device to be accessed.

[0058] In the embodiment of the present invention, after determining the target data access terminal of each device to be accessed according to the locations of all target locations and fixed terminals, the heterogeneous network access method of the present invention may further include:

[0059] Monitor whether the number of data access terminals changes; when a change in the number of data access terminals is detected, perform the step of determining the location and required bandwidth of each data access terminal until there are no available data access terminals.

[0060] Specifically, the edge computing device will continuously monitor whether the number of data access terminals has changed. When the number of data access terminals is monitored to have changed, it indicates that a data access terminal has entered an unavailable state (powered off or leaving the site) or a new available data access terminal has been added. At this time, the edge computing device will re-determine the target data access terminal of each device to be accessed, that is, execute steps 101 to 104 until there are no available data access terminals, and the edge computing device stops monitoring the number of data access terminals. In this way, the present invention realizes the dynamic adjustment of the access of the device to be accessed, and improves the overall access performance of the present invention.

[0061] The embodiment of the present invention adopts the above-mentioned technical solution, introduces edge computing technology, and adopts edge computing devices to determine the location and required bandwidth of each data access terminal. Edge computing technology has the advantages of low latency and high reliability, so that the present invention can improve the efficiency and reliability of obtaining the location and required bandwidth of each data access terminal, thereby improving the efficiency and reliability of the access of the device to be accessed to the data access terminal; and, by determining the target positions of the individual terminal, the vehicle-mounted terminal and the mobile terminal according to the bandwidth demand spatial distribution map, the present invention can realize the deployment of the individual terminal, the vehicle-mounted terminal and the mobile terminal at the optimal position, thereby reducing the overlapping area of ​​network coverage at the emergency site, balancing the access performance of the entire network, and avoiding the occurrence of data transmission bottlenecks caused by excessive local access data; on the basis of determining the target positions of the individual terminal, the vehicle-mounted terminal and the mobile terminal, the present invention also determines the target data access terminal of each device to be accessed according to the positions of all target positions and fixed terminals, so that the present invention can improve the rationality of resource allocation. It can be seen that by determining the target positions of individual terminals, vehicle-mounted terminals and mobile terminals according to the bandwidth demand spatial distribution map, and determining the target data access terminal of each device to be accessed according to the locations of all target positions and fixed terminals, the present invention can improve the access performance of the device to be accessed to the data access terminal.

[0062] Based on a general inventive concept, the present invention also provides an edge computing device. Figure 2 Schematic diagram of the structure of an edge computing device provided by an embodiment of the present invention. Figure 2 As shown, the device comprises:

[0063] The first determination module 21 is used to determine the location and required bandwidth of each data access terminal; the data access terminal includes a single-soldier terminal, a vehicle-mounted terminal, a mobile terminal and a fixed terminal.

[0064] The construction module 22 is used to construct a bandwidth demand spatial distribution map according to the location and the required bandwidth.

[0065] The second determination module 23 is used to determine the target positions of the individual terminal, the vehicle-mounted terminal and the mobile terminal according to the bandwidth demand spatial distribution diagram.

[0066] The third determining module 24 is used to determine the target data access terminal of each device to be accessed according to the locations of all target locations and fixed terminals.

[0067] Optionally, the edge computing device of the present invention may further include:

[0068] The monitoring module is used to monitor whether the number of data access terminals changes. When the number of data access terminals changes, the monitoring module is notified to execute the step of determining the location and required bandwidth of each data access terminal until there are no available data access terminals.

[0069] Based on a general inventive concept, the present invention also provides a heterogeneous network access system. Figure 3 Schematic diagram of a heterogeneous network access system provided by an embodiment of the present invention. Figure 3 As shown, the system includes: a data access terminal module 31, a northbound interface module 32 and the edge computing device 33 as described above.

[0070] The data access terminal module 31 includes a single-soldier terminal, a vehicle-mounted terminal, a mobile terminal and a fixed terminal.

[0071] The edge computing device 33 is used to adopt the heterogeneous network access method as described above to determine the target data access terminal of each device to be accessed in the data access terminal module.

[0072] The data access terminal module 31 obtains the transmission data from the device to be accessed, and inputs it into the target data network (ie, the rear data management system) through the northbound interface module 32 to provide the rear with real-time emergency on-site data information.

[0073] Optionally, the northbound interface module 32 includes a production data northbound interface and an operation data northbound interface. When the transmission data is production data, the transmission data is input into the production data network through the production data northbound interface; when the transmission data is operation data, the transmission data is input into the integrated data network through the operation data northbound interface. In this way, by distinguishing data types, data of different data types are transmitted through different data interfaces, which reduces the risk of data leakage and improves the security of the overall network.

[0074] Optionally, the northbound interface module is also used to determine whether the transmission data needs to be encrypted before sending the transmission data to the corresponding target data network; if the transmission data needs to be encrypted, the transmission data is encrypted and then sent to the corresponding target data network; if the transmission data does not need to be encrypted, the transmission data is directly sent to the corresponding target data network. In this way, by encrypting the transmission data on demand, the amount of calculation of the northbound interface module when performing data encryption can be effectively reduced.
