[0035] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described in detail below. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0036] Power emergency repair is a key link for quickly restoring power supply in natural disasters or other emergency situations. In the power emergency repair scene, the communication needs of the on-site devices (such as sensors, monitoring cameras, etc.), detection or repair equipment (such as testers, generators, etc.), on-site personnel side devices and repair vehicles need to be met.

[0037] In the power emergency repair scene, the type, location and quantity of devices are uncertain, and the traditional industrial heterogeneous network has low flexibility, so it is difficult to meet the communication needs of the devices in the power emergency repair scene, and it is easy to cause mutual interference of the southward data due to the access of multiple southward data from a single node.

[0038] Based on this, the present application provides a wireless backbone communication system of a heterogeneous network fusion, which can meet the communication needs of the devices in the power emergency repair scene and avoid mutual interference of the southward data.

[0039] The technical solutions of the present application will be described in detail below with reference to the drawings.

[0040] Figure 1 Figure 1 is a structural schematic diagram of a wireless backbone communication system of a heterogeneous network fusion provided by an embodiment of the present application. As shown in Figure 1 The wireless backbone communication system of the heterogeneous network fusion includes a southward access module 11, an Ad-Hoc (point-to-point) data transmission module 12 and at least one northward output module 13.

[0041] The southward access module 11 supports accessing a plurality of first devices, which can be devices operated by a power emergency repair site, emergency rescue equipment, emergency rescue vehicles, and emergency rescue individual devices, etc. The data collected by the first devices can be transmitted to second devices, which can be computers and smart phones, etc., so that the power emergency repair personnel can read the data collected by the first devices through the data displayed by the second devices, and then understand the site situation. In addition, the data collected by the first devices can also be finally transmitted to the related nodes in the point-to-point data transmission module 12, at this time, the destination node of the data (i.e. transmission data) collected by the first devices is the related nodes in the point-to-point data transmission module 12.

[0042] In actual application process, when the southward access module 11 receives the transmission data sent by the first device, the transmission data is sent to the point-to-point data transmission module 12 after protocol conversion.

[0043] The point-to-point data transmission module 12 determines the destination node of the transmission data after receiving the transmission data, plans the target path of the transmission data according to the destination node, and transmits the transmission data according to the target path. In the specific implementation process, the point-to-point data transmission module 12 includes a route detection unit and a data distribution unit. The route detection unit is used to determine the destination node of the transmission data after receiving the transmission data, and plans the target path of the transmission data according to the destination node. The route detection unit can specifically plan the target path according to the shortest time estimation method, so as to maximize the time length of transmitting the transmission data, reduce the data transmission delay, and improve the network resource utilization efficiency. The data distribution unit is used to transmit the transmission data according to the target path.

[0044] When the destination node is a second device connected to the northward output module 13, the transmission data is output from the point-to-point data transmission module 12 and input into the corresponding second device through the corresponding northward output module 13.

[0045] The embodiment of the application adopts the above technical solution, and realizes decentralized data transmission and dynamic routing by adopting a distributed access technology (i.e. a point-to-point data transmission module), so that the application can support any wireless ad hoc network device to freely join or leave the network, and has high flexibility, and thus the application can meet the device communication demand in the power emergency repair scene, and can avoid the mutual interference of southward data by avoiding the access of a plurality of southward data from a single node.

[0046] It should be noted that the heterogeneous network integrated wireless backbone communication system of the present application is implemented by a plurality of wireless ad hoc network devices, each of which includes a southbound access structure, a point-to-point data transmission structure and a northbound output structure, the southbound access structures of all wireless ad hoc network devices constitute a southbound access module 11, and for the same reason, the point-to-point data transmission structures of all wireless ad hoc network devices constitute a point-to-point data transmission module 12, and the northbound output structures of all wireless ad hoc network devices constitute all northbound output modules 13.

[0047] In the embodiment of the present application, the point-to-point data transmission module 12 can be specifically used for:

[0048] When it is necessary to upload the target transmission data sent by the target first device to the preset data center, the point-to-point data transmission module 12 controls the target transmission data to be transmitted to a second device, and the target transmission data is uploaded to the preset data center through the second device, so as to avoid repeated uploading of data.

[0049] The second device is connected with the corresponding northbound output module 13, and is used for uploading the transmission data to the preset data center when receiving the transmission data.

[0050] In a specific example, it is assumed that the first device includes a sensor 1, a sensor 2 and a sensor 3, the second device includes a target computer and a target smart phone, and the wireless ad hoc network device includes a wireless ad hoc network device 1, a wireless ad hoc network device 2, a wireless ad hoc network device 3 and a wireless ad hoc network device 4. The distances between the three sensors are relatively far, so the wireless ad hoc network device 1 is arranged near the sensor 1, the wireless ad hoc network device 2 is arranged near the sensor 2, the wireless ad hoc network device 3 is arranged near the sensor 3, and the wireless ad hoc network device 4 is arranged near the target computer.

[0051] In actual application, at the beginning, the data collected by the sensor 1 is input into the target computer after sequentially passing through the wireless ad hoc network device 1, the wireless ad hoc network device 2, the wireless ad hoc network device 3 and the wireless ad hoc network device 4; the data collected by the sensor 2 is input into the target computer after sequentially passing through the wireless ad hoc network device 2, the wireless ad hoc network device 3 and the wireless ad hoc network device 4; the data collected by the sensor 3 is input into the target computer after sequentially passing through the wireless ad hoc network device 3 and the wireless ad hoc network device 4. Later, a repairman comes to the vicinity of the sensor 3 and checks the data collected by the sensor 3, at this time, the smart phone carried by the repairman is the target smart phone (the repairman can also use other devices to replace the smart phone), since the target smart phone is closer to the wireless ad hoc network device 3 than the target computer, the wireless ad hoc network device 3 can send the data collected by the sensor 3 to the target smart phone, since each second device will upload the data collected by the first device to the preset data center when receiving the data, in order to avoid the data collected by the sensor 3 being repeatedly uploaded to the preset data center and causing resource waste, the data collected by the sensor 3 is no longer sent to the target computer but only sent to the target smart phone.

[0052] In the embodiment of the application, the point-to-point data transmission module 12 can be further used for:

[0053] For the target path that has been planned, if all the transmission nodes corresponding to the target path do not change, the corresponding transmission data is continued to be transmitted by using the target path.

[0054] If some of the transmission nodes corresponding to the target path change, the corresponding transmission data is re-planned for the target path.

[0055] According to the foregoing example, for the sensor 1, it is assumed that the data collected by the sensor 1 is input to the target computer in sequence through the wireless ad hoc network device 1, the wireless ad hoc network device 2, the wireless ad hoc network device 3 and the wireless ad hoc network device 4. In this case, when the wireless ad hoc network device 1, the wireless ad hoc network device 2, the wireless ad hoc network device 3 and the wireless ad hoc network device 4 do not change, the data collected by the sensor 1 is always input to the target computer in sequence through the wireless ad hoc network device 1, the wireless ad hoc network device 2, the wireless ad hoc network device 3 and the wireless ad hoc network device 4. However, if the wireless ad hoc network device 1, the wireless ad hoc network device 2, the wireless ad hoc network device 3 and the wireless ad hoc network device 4 change, for example, the wireless ad hoc network device 4 fails and the wireless ad hoc network device 5 is added, the target path planning is performed again, for example, the data collected by the sensor 1 is input to the target computer in sequence through the wireless ad hoc network device 1, the wireless ad hoc network device 2, the wireless ad hoc network device 3 and the wireless ad hoc network device 5. In this way, the resource consumption of the point-to-point data transmission module 12 is reduced, and the data transmission efficiency of the power emergency repair site is improved.

[0056] In the embodiment of the present application, as shown in Figure 1 The southbound access module 11 includes a first wired interface, a first wireless interface and a first protocol conversion unit.

[0057] The first wired interface and the first wireless interface are used to receive the transmission data sent by the first device and send the transmission data to the first protocol conversion unit.

In this way, the interface types are rich, so that the present application can meet the access requirements of various first devices.

[0059] The first protocol conversion unit is used to send the transmission data to the point-to-point data transmission module 12 after protocol conversion.

[0060] In the embodiment of the present application, the LoRa interface can access the southbound access module 11 in a wired manner. In this way, the data received by the LoRa base station can be retrieved in a wired manner, reducing the difficulty of obtaining data in the LoRa base station.

[0061] In the embodiment of the present application, as shown in Figure 1As shown, the northbound output module 13 includes a data type detection unit, a second protocol conversion unit and an interface unit.

[0062] The data type detection unit is configured to identify and verify the data format of the transmission data after receiving the transmission data sent by the point-to-point data transmission module 12, and send the transmission data to the second protocol conversion unit after the transmission data is verified.

[0063] The second protocol conversion unit is configured to send the transmission data to the interface unit after protocol conversion.

[0064] The interface unit is configured to send the transmission data to the second device connected thereto.

The secret data can be production data.
