Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of data processing, and in particular to a data transmission method, system, device, electronic device, and computer-readable storage medium. Background Art

[0002] In order to detect environmental data such as temperature, humidity, wind speed, and landform in remote areas such as mountains, islands, deserts, and gobi, a large number of environmental sensors have been deployed in these areas to collect relevant environmental data. Since there is no ground base station network coverage in these remote areas, it is impossible to quickly transmit environmental data to the server through the network.

[0003] In one solution, researchers drive a vehicle to the location of the sensor and copy the environmental data in the environmental sensor to a mobile hard disk. This method is time-consuming and laborious, and the efficiency is relatively low. In another solution, a ground terminal of a low-earth orbit satellite is deployed at each location where sensors are concentrated. The ground terminal is connected to the low-earth orbit satellite to send environmental data to the low-earth orbit satellite, and the environmental data is forwarded to the server through the low-earth orbit satellite. However, this solution requires a ground terminal to be deployed at each location where sensors are concentrated, resulting in high deployment costs and operating costs. Summary of the Invention

[0074] Next, the technical solutions in the present application will be clearly and completely described in conjunction with the accompanying drawings in the present application. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.

[0075] In one embodiment, as Figure 1 shown, a data transmission method is provided. Although the logical order is shown in the step schematic diagram, in some cases, the steps shown or described can be executed in an order different from that shown in the drawings. Specifically, the data transmission method can be applied to a mobile device, and the mobile device can move. In one embodiment, the mobile device can be an autonomous vehicle.

[0076] The following will be described in detail respectively. It should be noted that the description order of the following embodiments does not limit the priority order of the embodiments.

[0077] According to Figure 1 the data transmission method shown, the method at least includes steps S110 to S130, which are introduced in detail as follows:

[0078] In step S110, when entering the target area, a local area network is established with at least one data acquisition device in the target area.

[0079] The target area is an area where a local area network can be established with a data acquisition device. Since the coverage range of the local area network is limited, when the mobile device enters the target area, a local area network can be established with the data acquisition devices in the target area. In one embodiment, the target area can be an area where data acquisition devices are concentrated, and the target area includes multiple data acquisition devices.

[0080] As Figure 2Schematic diagram of the movement path of the mobile device shown. The target area A, target area B, and target area C can be areas where data collection devices are concentrated respectively. After the mobile device enters the target area A, it can establish a first local area network with multiple data collection devices in the target area A; after the mobile device leaves the target area A, because the coverage of the local area network is limited, the first local area network will be disconnected; after the mobile device enters the target area B, it can establish a second local area network with multiple data collection devices in the target area B; similarly, after the mobile device leaves the target area B, the second local area network will also be disconnected; after the mobile device enters the target area C, it can establish a third local area network with multiple data collection devices in the target area C; after the mobile device leaves the target area C, the third local area network will be disconnected.

[0081] The data collection device can be an environmental sensor, and the data collected by the environmental sensor can be environmental data such as temperature, humidity, wind force, and / or landform.

[0082] In remote areas such as mountains, islands, deserts, and gobi, because there is no ground base station network coverage, there is no 2G (the 2nd Generation, the second-generation wireless communication technology), 3G (the 3rd Generation, the third-generation wireless communication technology), 4G (the 4th Generation, the fourth-generation wireless communication technology), LTE (Long Term Evolution, long-term evolution technology), or 5G (the 5th Generation, the fifth-generation wireless communication technology) network, nor is there Wi-Fi Internet. Conventional Wi-Fi Internet needs to connect to the Internet through a wireless access point (such as a wireless router). The device searches for and connects to a known Wi-Fi network, and after entering authentication information such as a password, it can access the Internet to realize data interaction between the device and the Internet server.

[0083] The local area network established by the mobile device can be a Wi-Fi Aware network. In a Wi-Fi Aware network, devices can discover each other by actively broadcasting and receiving specific signals, without connecting to a traditional network infrastructure (such as a wireless router) or the Internet, so as to directly establish a connection between devices. For example, in an outdoor scenario without network coverage, devices supporting Wi-Fi Aware can directly discover and connect to each other.

[0084] In step S120, within the local area network, receive the data sent by the data collection device.

[0085] In the local area network, communication can be carried out between the mobile device and the data collection device. The mobile device can receive the data sent by each data collection device within the local area network.

[0086] In step S130, the data is sent to the server.

[0087] After receiving the data sent by the data acquisition device, the mobile device can send the data to the server.

[0088] In one embodiment, in order to quickly send the data to the server, the mobile device may include a ground terminal of a satellite. Through the ground terminal of the satellite, the data is quickly sent to the satellite so that the satellite forwards the data to the server. Among them, the satellite may be a low-earth orbit satellite.

[0089] In another embodiment, considering the satellite communication traffic cost and in order to save costs, when the mobile device moves to an area covered by the ground base station network, it can send the data to the server through the ground base station network.

[0090] Adopting the technical solution of the embodiment of the present application, after the mobile device enters the target area, it can form a local area network with the data acquisition devices in the target area, so as to receive the data sent by the data acquisition devices within the local area network; and then it can send the data to the server. The mobile device can move. Therefore, a mobile device can form local area networks in each target area and receive the data sent by the data acquisition devices in each target area. Compared with deploying ground terminals at the locations where each sensor is concentrated, the deployment cost and operation cost can be reduced, and the data can be sent to the server quickly and efficiently.

[0091] Based on the above technical solution, as an embodiment, receiving the data sent by the data acquisition device within the local area network may include: receiving the data volumes sent by each of the data acquisition devices; the data volume is the data volume of the data to be sent by the data acquisition device; obtaining the data transmission rate and the distance to be moved in the target area; determining the moving speed according to the sum of the data volumes, the data transmission rate, and the distance to be moved; moving at the moving speed, and receiving the data sent by each of the data acquisition devices before leaving the target area.

[0092] In one embodiment, as Figure 2 shown, the mobile device can move periodically according to a preset moving path. When the mobile device moves according to the preset moving path, it can form a local area network with the data acquisition devices in the concentrated area of each data acquisition device.

[0093] After the mobile device forms a local area network with the data acquisition device, the data acquisition device can first send the data volume to the mobile device to inform the mobile device of the data volume of the data to be sent by the data acquisition device. After receiving the data volumes sent by each data acquisition device, the mobile device can determine the sum of the data volumes sent by each data acquisition device as the sum of the data volumes to be received within the local area network.

[0094] After the mobile device drives out of the target area, due to the limited coverage of the local area network, the local area network will be interrupted. The mobile device needs to ensure that it receives the data sent by each data acquisition device within the local area network before driving out of the target area.

[0095] The range of the target area can be determined through experiments or calculations. The mobile device can determine the remaining moving distance within the target area, which can be: the total distance of the preset moving path of the mobile device within the target area minus the distance the mobile device has traveled within the target area. The target correspondence between each position within the target area and the remaining moving distance within the target area can be preset. The mobile device can obtain its current position in real time, and thus query the target correspondence according to the current position to determine the remaining moving distance within the target area.

[0096] The mobile device can directly obtain the data transmission rate from the parameters of the local area network or obtain the data transmission rate through experiments.

[0097] The mobile device can determine the moving speed according to the sum of the data volumes, the data transmission rate, and the remaining moving distance. Moving at this moving speed can ensure that before leaving the target area, the mobile device receives the data sent by each data acquisition device within the target area. Among them, the sum of the data volumes can be divided by the data transmission rate to determine the time required to transmit all the data. Dividing the remaining moving distance by this time can obtain the maximum moving speed. The moving speed of the mobile device can be less than or equal to the maximum moving speed.

[0098] Before leaving the target area, the mobile device can maintain the local area network connection. If the mobile device receives the data sent by each data acquisition device before leaving the target area, it can also actively disconnect the local area network connection in advance.

[0099] By adopting the technical solution of the embodiment of the present application, it is possible to determine the moving speed according to the sum of the data volumes, the data transmission rate, and the remaining moving distance. The mobile device moving at this moving speed can ensure that before leaving the target area, it receives the data sent by each data acquisition device, thereby avoiding the problem of missing received data due to too fast moving speed.

[0100] Based on the above technical solution, as an embodiment, receiving the data sent by each of the data acquisition devices may include: receiving the data sent by each of the data acquisition devices in ascending order of the data volume sent by each of the data acquisition devices.

[0101] After receiving the data volumes sent by each data acquisition device, the mobile device may arrange each data volume and the number of the data acquisition device corresponding to each data volume in ascending order of the data volume, and receive the data sent by each data acquisition device in ascending order of the data volume.

[0102] In one embodiment, arranging each data volume and the number of the data acquisition device corresponding to each data volume in ascending order of the data volume may obtain Table 1. Then, when receiving the data sent by each data acquisition device, first receive the data sent by the data acquisition device numbered 012, and then receive the data sent by the data acquisition device numbered 003 until all the data sent by each data acquisition device is received.

[0103] Table 1. Data Volume List

[0104] Data acquisition device number Data volume 012 500M 003 650M … … 027 2.5G

[0105] Adopting the technical solution of the embodiment of the present application, because the transmission of small data volumes takes a short time, the transmission can be completed faster, and the waiting time can be reduced. Therefore, the data with smaller data volumes is received first; and if a large data volume is received at the beginning, it may instantaneously occupy a large amount of network bandwidth, resulting in network congestion; in addition, if an error or interruption occurs, the retransmission cost of small data volumes is low. If a large data volume is transmitted first and the transmission fails, the retransmission not only takes time but may also affect the subsequent data transmission. By transmitting small data volumes first, even if problems occur, the impact on the overall data reception is small, the system recovery is easier, and the stability is higher.

[0106] Based on the above technical solution, as an embodiment, before sending the data to the server, the method may further include: preprocessing the data; the preprocessing includes: combining like terms, deleting irrelevant terms, and compressing.

[0107] After receiving the data sent by the data acquisition device, the mobile device may first preprocess the data to reduce the data volume sent to the server and reduce the traffic cost of satellite communication.

[0108] Among them, preprocessing the data may include, but is not limited to, combining like terms, deleting irrelevant items, and compressing the data. Combining like terms may be to merge and integrate data with the same characteristics or attributes to simplify the data structure, improve the data processing efficiency, and the accuracy of analysis. Deleting irrelevant items may refer to identifying and removing data elements, features, or records in the dataset that are irrelevant to a specific analysis objective, task, or model to improve the data quality, optimize the data analysis efficiency, and enhance the result accuracy. Compressing the data may be a process of reducing the storage space or transmission bandwidth requirements of the data through a specific algorithm without losing or minimizing the loss of necessary information to improve the storage efficiency and transmission speed.

[0109] After preprocessing the data, the preprocessed data is sent to the server.

[0110] Adopting the technical solution of the embodiment of the present application, preprocessing the data before sending the data to the server can effectively reduce the amount of data transmitted, save bandwidth, save transmission costs, and improve the transmission efficiency.

[0111] On the basis of the above technical solution, as an embodiment, the mobile device may include a ground terminal of a satellite; the sending the data to the server may include: sending the data to the satellite through the ground terminal of the satellite so that the satellite forwards the data to the server.

[0112] The mobile device may include a ground terminal of a satellite, which may be a ground terminal of a low-earth orbit satellite. The ground terminal may be linked to the low-earth orbit satellite and transmit data at high speed based on a liquid crystal phased array antenna. The liquid crystal phased array antenna refers to changing the dielectric constant of the liquid crystal material by applying different bias voltages to the liquid crystal materials below each antenna element, thereby changing the steering of the liquid crystal molecules, changing the propagation speed of the electromagnetic wave in the delay line, changing the phase of the electromagnetic wave of each antenna element, and finally changing the direction where the maximum gain of the antenna array is located (i.e., the direction of the main lobe of the antenna), that is, achieving the effect of phase scanning. For the liquid crystal phased array antenna, its input is different bias voltages, and the corresponding output is the scanning direction of the main lobe of the antenna array. Compared with the traditional electronic phased array antenna, the liquid crystal phased array antenna has the advantages of low cost and low power consumption.

[0113] The mobile device may be linked to a low-earth orbit satellite through a ground terminal based on a liquid crystal phased array antenna and send data to the low-earth orbit satellite. The low-earth orbit satellite, as a relay node, forwards the data to a ground measurement and control station, and the ground measurement and control station may upload the data to a cloud server. After receiving the data, the cloud server parses and deeply processes the data.

[0114] By adopting the technical solution of the embodiment of the present application, in places where the ground base station network coverage is unavailable, data can be directly sent to the satellite through the ground terminal on the mobile device, so as to quickly send the data to the server, enabling the server to process the data, improving the efficiency of transmitting the data to the server, and ensuring the timeliness of data processing.

[0115] Based on the above technical solution, as an embodiment, the local area network is a Wi-Fi sensing network. The establishment of the local area network with at least one data collection device in the target area may include: sending a discovery beacon frame; receiving the synchronization beacon frame sent by the at least one data collection device in response to the discovery beacon frame. Receiving the data sent by the data collection device within the local area network may include: receiving the service discovery frame sent by the data collection device within the local area network; extracting the data from the data body field of the service discovery frame.

[0116] The mobile device can act as the initiator of the Wi-Fi sensing network, establish the Wi-Fi sensing network, and maintain the normal operation of the Wi-Fi sensing network. The mobile device and multiple data collection devices send and receive signaling messages through the Wi-Fi sensing network, enabling the data collection device to quickly transmit data to the mobile device through a Wi-Fi Direct link when the mobile device passes by the data collection device. The mobile device is equipped with a Wi-Fi sensing transceiver module, a Wi-Fi Direct transceiver module, and a ground terminal.

[0117] The Wi-Fi sensing network is a low-power local area network defined by the Wi-Fi Alliance and has relatively wide applications in the Internet of Things field. The communication range of the Wi-Fi sensing network is a circular area with a radius of 100 meters. The mobile device can act as the initiator to establish the Wi-Fi sensing network, and multiple data collection devices join the network.

[0118] The Wi-Fi sensing network has three roles, namely the master device, the non-master synchronization device, and the non-master non-synchronization device. The establishment process of the Wi-Fi sensing network may include: the mobile device acts as the master device and sends a discovery beacon frame, which is used to discover numerous data collection devices to form a Wi-Fi sensing network, and numerous data collection devices randomly become the roles of the non-master synchronization device or the non-master non-synchronization device; the master device and the non-master synchronization device in the group send synchronization beacon frames; within the group, the master device, the non-master synchronization device, or the non-master non-synchronization device can send and receive service discovery frames to obtain specific information.

[0119] After the Wi-Fi sensing network is successfully established, each device in the network has an interface address (6 bytes) to distinguish different devices. Any device in the Wi-Fi sensing network can communicate one-to-one with any other device, one-to-many with multiple devices, or broadcast communicate in the network. The communication messages can be carried in the service discovery frame.

[0120] On the premise of conforming to the Wi-Fi sensing protocol, the devices in the Wi-Fi sensing network use the service discovery frame to send and receive specific messages to each other. The format of the service discovery frame is as Figure 3 shown. Among them, Category refers to the type of this frame as a Public Action Frame; Action Field refers to the public action frame related to the specified manufacturer; OUI refers to the Organizationally Unique Identifier; OUI Type refers to the type of OUI; Attributes refer to the attributes, including service description attributes and manufacturer-specific attributes. In the manufacturer-specific attributes, Attribute ID refers to the number of the manufacturer-specific attribute; Length refers to the byte length sum of OUI and Body; OUI refers to the number of the manufacturer; Body refers to the specific information of the manufacturer.

[0121] To better understand the format of the service discovery frame specified in an embodiment of the present application, Table 2 shows Figure 3 the simplified representation of the service discovery frame described, and the Body field in Table 2 is the Figure 3 data body (Body) field in

[0122] Table 2. Simplified Format of Service Discovery Frame

[0124] Table 3 is the definition and description of the message ID in Table 2.

[0125] Table 3. Definition and Description of Message ID

[0126]

[0127]

[0128] The mobile device broadcasts and sends a discovery beacon frame. After the data acquisition device receives the discovery beacon frame, the data acquisition device sends a synchronization beacon frame to the mobile device, thus completing the establishment of the local area network between the mobile device and the data acquisition device.

[0129] After the local area network is established, the mobile device can receive the service discovery frame sent by the data acquisition device within the local area network. The data body field of the service discovery frame contains the data sent by the data acquisition device. The mobile device can extract the data from the data body field of the service discovery frame.

[0130] By adopting the technical solution of the embodiment of the present application, in an area without ground base station network coverage, the mobile device can establish a Wi-Fi sensing network with the data acquisition device, so as to communicate with the data acquisition device in the Wi-Fi sensing network and obtain the data sent by the data acquisition device, realizing the rapid and efficient acquisition of the data in the data acquisition device.

[0131] On the basis of the above technical solution, as an embodiment, the method may further include: receiving the Wi-Fi direct connection addresses sent by each of the data acquisition devices. The receiving the data sent by each of the data acquisition devices may include: establishing a Wi-Fi direct connection link with the data acquisition device according to the Wi-Fi direct connection address sent by the data acquisition device; and receiving the data sent by the data acquisition device through the Wi-Fi direct connection link.

[0132] After the mobile device establishes a Wi-Fi sensing network, the mobile device can broadcast a message (as shown in Table 4) in the Wi-Fi sensing network to notify a plurality of data acquisition devices to report the data volume of the collected data. After receiving the message as shown in Table 4, the data acquisition device can send a message as shown in Table 5 to report the Wi-Fi direct connection address and the data volume.

[0133] Table 4. Message for the mobile device to notify the data acquisition device to report the data volume

[0134]

[0135] Table 5. Message for the data acquisition device to report the Wi-Fi direct connection address and the data volume

[0136]

[0137]

[0138] After receiving the Wi-Fi direct connection address sent by the data acquisition device, the mobile device can establish a one-to-one Wi-Fi direct connection link with the data acquisition device according to the Wi-Fi direct connection address sent by the data acquisition device, and receive the data sent by the data acquisition device through the Wi-Fi direct connection link.

[0139] Continuing with the embodiments described above, when the amount of data received by the mobile device is as shown in Table 1, the mobile device, in the order of Table 1, starts from the data acquisition device with the smallest amount of data and successively establishes Wi-Fi direct connections with numerous data acquisition devices to transfer data at high speed. The mobile device first establishes a Wi-Fi direct connection with the data acquisition device numbered 012 in Table 1. The data acquisition device numbered 012 transfers data to the mobile device at high speed through the Wi-Fi direct connection. Then, the mobile device establishes a Wi-Fi direct connection with the data acquisition device numbered 003 in Table 1. The data acquisition device numbered 003 transfers data to the mobile device at high speed through the Wi-Fi direct connection, and so on. After the mobile device receives the data from all data acquisition devices, the mobile device notifies the numerous data acquisition devices of the message that the data transmission is complete as shown in Table 6, and then disbands the Wi-Fi sensing network.

[0141]

[0142] The mobile device continues to move along the preset travel path. When moving to the next target area, it forms a Wi-Fi sensing network in the same way. Numerous data acquisition devices join the Wi-Fi sensing network, and the data acquisition devices transfer data to the mobile device at high speed through Wi-Fi direct connections. Finally, the mobile device performs preprocessing operations such as combining like terms, deleting irrelevant items, and integrating and compressing all data to reduce the overall amount of data and form a compressed data packet.

[0143] Adopting the technical solution of the embodiment of the present application, the mobile device can transfer data with each data acquisition device in turn without relying on intermediate devices such as routers. As long as the device supports Wi-Fi direct connection, a connection can be quickly established, and data can be transferred at any time and anywhere, without being restricted by a specific network environment. The operation is simple, saving the time and effort of setting up the network; reducing the forwarding link of intermediate devices, the data is directly transferred between devices, the path is shorter, the transmission delay is low, and a higher data transmission rate can be achieved.

[0144] To facilitate better implementation of the data transmission method of the present application, the present application also provides a data transmission system based on the above data transmission method.
