[0004] Another example is that the specification of Chinese Patent CN119484616A discloses a communication data processing system and method based on edge computing, belonging to the technical field of data processing.

[0005] Existing edge devices often have network attack incidents during data transmission, resulting in the interception and tampering of data, causing data leakage and even the dangerous consequences of the terminal being attacked and invaded by viruses. Summary of the Invention

[0006] Aiming at the above-mentioned prior art, the technical problem to be solved by the present invention is that existing edge devices often have network attack incidents during data transmission, resulting in the interception and tampering of data, causing data leakage and even the dangerous consequences of the terminal being attacked and invaded by viruses.

[0007] To solve the above problems, the present invention provides a self - controllable data communication system, including an edge data communication device and a receiving terminal. Data is transmitted between the edge data communication device and the receiving terminal through a relay verification device. There are multiple network transmission paths for data transmission between the edge data communication device and the relay verification device. Wired transmission is performed between the relay verification device and the receiving terminal. The edge data communication device includes a data splitting module, an adjustment output module, a forward receiving module, a reverse receiving module, and a network monitoring module. The forward receiving module is used to collect sensing data. The data splitting module is used to split the sensing data to achieve the conversion of one data into multiple data. The adjustment output module is used to transmit the split sensing data to the relay verification device through different network transmission paths respectively. The reverse receiving module is used to receive the data fed back by the relay verification device. The network monitoring module is used to monitor the fluctuations of multiple network transmission paths.

[0008] A self - controllable data communication system, and its usage method includes the following steps:

[0009] Step 1: The edge data communication device splits the collected complete data into multiple data single - body packets. Assume that there are a total of w network transmission paths;

[0010] Step 2: When there is no obvious network fluctuation in the network transmission paths, different data single - body packets are respectively transmitted through different network transmission paths to the relay verification device, and then the relay verification device sends them to the receiving terminal through a wired transmission method;

[0011] Step 3: When obvious network fluctuations are detected, the w transmission paths are randomly and evenly grouped into a total of n groups, with each group containing m paths, that is, n * m = w. Different groups transmit different data single - body packets, and the m paths in the same group transmit the same data single - body packet at the same time;

[0012] After the data reaches the relay verification device, compare the m data single - body packets transmitted by the m paths in the same group. The data single - body packets with exactly the same data content are regarded as normal data packets, and the network transmission paths corresponding to them are normal paths. The data single - body packets with data content different from the normal data packets are defined as abnormal data packets, and the network transmission paths corresponding to them are abnormal paths. At this time, the relay verification device gives a security feedback to the edge data communication device to stop using the abnormal paths, and at the same time, the relay verification device issues a network warning to the receiving terminal;

[0013] Step 4: When, after a set time, the relay verification device still receives data from the abnormal paths, indicating that the security feedback has failed. At this time, first issue a warning to the receiving terminal again, and then stop the relay verification device from transmitting data to the receiving terminal.

[0014] As a further supplement to the present application, the transfer verification device includes a device body. A connector is fixedly connected to the side end of the device body, and the connector is hardware-connected to the receiving terminal. A controller is fixedly connected inside the device body. The controller includes a transfer system, and the transfer system includes a data transmission module, a data detection module, a security feedback module, an alarm module, a security database, and an abnormal database.

[0015] As a further supplement to the present application, the data transmission module is used to receive data from the edge data communication device and send data to the receiving terminal. The data detection module is used to detect the data single packet. The security feedback module is used to perform security feedback to the edge data communication device. The security database is used to store normal data packets, and the abnormal database is used to store abnormal data packets.

[0016] As another improvement of the present application, an inner cavity is provided inside the device body. A dynamic conductor is slidably connected inside the inner cavity. A secondary conductor is fixedly connected inside the device body. One end of the controller close to the dynamic conductor is electrically connected to a main conductor. In the initial state, the dynamic conductor is located between the main conductor and the secondary conductor and is in contact with each other.

[0017] As a supplementary improvement of the present application, a transmission line is electrically connected to the side end of the secondary conductor, and the end of the transmission line away from the secondary conductor is electrically connected to the connector.

[0018] As a supplementary improvement of the present application, an electric telescopic rod is also fixedly connected inside the device body. The telescopic end of the electric telescopic rod movably penetrates the device body and contacts the side end of the dynamic conductor. The transfer system also includes an active cut-off module, and the electric telescopic rod is electrically connected to the active cut-off module.

[0019] As a supplementary improvement of the present application, a side cavity is also provided inside the device body. Air flow channels communicating with the inner cavity are provided at both ends of the side cavity, and the air flow channels are respectively located on both sides of the inner cavity. A flexible sealing sleeve is provided inside the side cavity. The two ends of the flexible sealing sleeve are respectively fixedly connected to a pair of inner walls of the side cavity, and the air flow channels communicate with the inside of the flexible sealing sleeve. Air holes communicating with the outside are provided on the inner wall of the side cavity.

[0020] As a supplementary improvement of the present application, a visual inspection rod is provided at the end of the dynamic conductor away from the electric telescopic rod. The visual inspection rod includes a rod body and a pair of end heads fixedly connected to both ends of the rod body. The rod body movably penetrates the device body and extends to the outside, and the pair of end heads are respectively located inside the inner cavity and outside.

[0021] As a supplementary improvement of the present application, magnetic coating is applied to the ends of the pair of rod bodies close to each other, the inner wall of the inner cavity away from the electric telescopic rod, and a partial outer end of the device body.

[0022] In summary, in the present application, a transit verification device is set between the edge network device and the receiving terminal, and multiple network transmission paths are used for data transmission between the edge network device and the transit verification device, while wired transmission is used between the transit verification device and the receiving terminal. Under normal circumstances, multiple network transmission paths are used to transmit different data monomer packets split from the same data respectively, effectively reducing the situation where the complete data is intercepted by lawbreakers. When network fluctuations are detected, the transmission paths are grouped, and the same data monomer packets are transmitted using the paths in the same group. Through the detection of the data monomer packets, the abnormal transmission paths with risks can be effectively judged and fed back to the edge network device to disable them, further improving data security. When the feedback fails, the transmission between the transit verification device and the receiving terminal is disconnected in a timely manner, effectively improving the security of the receiving terminal and its data.

Detailed implementation manners

[0034] The following will make a detailed description of two implementation manners of the present application with reference to the accompanying drawings.

[0035] The 1st implementation manner:

[0036] The present invention provides an autonomous and controllable data communication system. Please refer to Figure 1 , which includes an edge data communication device (denoted by N in the figure) and a receiving terminal (denoted by M in the figure). Data is transmitted between the edge data communication device and the receiving terminal through a transfer verification device. As shown in Figure 3 , there are multiple network transmission paths for data transmission between the edge data communication device and the transfer verification device, and wired transmission is performed between the transfer verification device and the receiving terminal.

[0037] Please refer to Figure 2 , the edge data communication device includes a data splitting module, an adjustment output module, a forward receiving module, a reverse receiving module, and a network monitoring module. The forward receiving module is used to collect sensing data. The data splitting module is used to split the sensing data to achieve the conversion of one data into multiple data. The adjustment output module is used to transmit the split sensing data to the transfer verification device through different network transmission paths respectively. The reverse receiving module is used to receive the data fed back by the transfer verification device. The network monitoring module is used to monitor the fluctuations of multiple network transmission paths.

[0038] An autonomous and controllable data communication system, and its usage method includes the following steps:

[0039] Step 1: The edge data communication device splits the collected complete data into multiple data single packets. Assume that there are a total of w network transmission paths;

[0040] Step 2: When there is no obvious network fluctuation in the network transmission path, different data single packets are respectively transmitted to the transfer verification device through different network transmission paths, and then the transfer verification device sends them to the receiving terminal through a wired transmission method;

[0041] Using multiple network transmission paths to transmit different data single packets split from the same data can effectively reduce the situation where the complete data is intercepted by lawbreakers. Even if one or more network transmission paths are attacked, it is difficult for lawbreakers to obtain the complete data content. This is the first protection measure to improve data transmission security;

[0042] Step 3: When obvious network fluctuations are detected, such as Figure 4 shown in the figure, randomly and evenly group the w transmission paths into n groups, with each group containing m paths, that is, n*m = w. Different groups transmit different data monomer packets, while the m paths in the same group transmit the same data monomer packet simultaneously;

[0043] After the data arrives at the transit verification device, compare the m data monomer packets transmitted by the m paths in the same group. Regard the data monomer packets with exactly the same data content as normal data packets, and the network transmission paths corresponding to them are normal paths. Define the data monomer packets with different data content from the normal data packets as abnormal data packets, and the network transmission paths corresponding to them are abnormal paths. At this time, the transit verification device gives a security feedback to the edge data communication device to stop using the abnormal path, and at the same time, the transit verification device issues a network warning to the receiving terminal;

[0044] When there are network fluctuations, it may be a normal fluctuation situation, or there may be a situation where the network is maliciously attacked. Moreover, the transmission paths without fluctuations are not necessarily safe paths. Therefore, at this time, there is an insecure risk in the network data transmission between the edge data device and the transit verification device, and it is difficult to judge the security status of each transmission path. Therefore, in order to improve data security and judge the status of network transmission paths, the operation in Step 3 is carried out; for the same data monomer packet transmitted by the m paths in the same group, if the data monomer packets transmitted by m' paths among them are the same (including data packet size, storage time, data content, etc.), it indicates that the above data monomer packet has not been tampered with, and to a certain extent, it also indicates that the corresponding m' paths are safe, and they are recorded as normal paths. If the data monomer packets transmitted by another part of the paths are inconsistent with the above data monomer packet (including any item such as data packet size, storage time, data content, etc.), it indicates that this data monomer packet may have been tampered with, then record the corresponding transmission path as an abnormal path, and perform security feedback, warning and other operations in Step 3. On the one hand, make the edge data communication device no longer use the abnormal path for data transmission. On the other hand, through the network warning, enable personnel to timely perform security detection on the abnormal transmission path to reduce the probability of additional losses. This is the second protection measure to improve data transmission security.

[0045] Step 4: When, after the set time, the transit verification device still receives data from the abnormal path, it indicates that the security feedback has failed (it may be that the transit verification device has received a malicious attack resulting in the failure of the feedback, or it may be that the edge data communication device has received an attack resulting in the failure of the response). At this time, first issue a warning to the receiving terminal again, and then stop the transit verification device from transmitting data to the receiving terminal, so that malicious attacks or viruses are not easily transmitted to the receiving terminal through the transit verification device. This is a protection measure to improve the security of the receiving terminal and its data.

[0046] Please refer to Figure 5 and Figure 6 The transit verification device includes a device body 1. A connector 2 is fixedly connected to the side end of the device body 1. The connector 2 is hardware-connected to the receiving terminal. A controller 3 is fixedly connected inside the device body 1. The controller 3 includes a transit system. The transit system includes a data transmission module, a data detection module, a security feedback module, an alarm module, a security database, and an abnormal database. The data transmission module is used to receive data from the edge data communication device and send data to the receiving terminal. The data detection module is used to detect data single packets. The security feedback module is used to give security feedback to the edge data communication device. The security database is used to store normal data packets. The abnormal database is used to store abnormal data packets.

[0047] The second implementation method:

[0048] On the basis of the first implementation method, the following specific settings are made for the transit verification device: Please refer to Figure 6 and Figure 7 An inner cavity 101 is opened inside the device body 1. A dynamic conductor 5 is slidably connected inside the inner cavity 101. A secondary conductor 6 is fixedly connected inside the device body 1. One end of the controller 3 close to the dynamic conductor 5 is electrically connected to a main conductor 4. In the initial state, the dynamic conductor 5 is located between the main conductor 4 and the secondary conductor 6 and is in contact with each other. The side end of the secondary conductor 6 is electrically connected to a transmission line 7. One end of the transmission line 7 away from the secondary conductor 6 is electrically connected to the connector 2.

[0049] An electric telescopic rod 8 is also fixedly connected inside the device body 1. The telescopic end of the electric telescopic rod 8 movably penetrates the device body 1 and contacts the side end of the dynamic conductor 5. The transit system further includes an active cut-off module. The electric telescopic rod 8 is electrically connected to the active cut-off module;

[0050] Through the setting of the above structure, in step four, while stopping the transit verification device from transmitting data to the receiving terminal, the following physical disconnection operations can also be performed: Combining Figure 8 As shown, the electric telescopic rod 8 is started through the active cut-off module, so that the electric telescopic rod 8 extends, pushing the dynamic conductor 5 to gradually move away from the main conductor 4 and the secondary conductor 6, thereby disconnecting the connection between the main conductor 4 and the secondary conductor 6, so that the controller 3 cannot continue to transmit data to the receiving terminal through the transmission line 7 and the connector 2, thereby further improving the security of the receiving terminal on the basis of step four.

[0051] Moreover, since the movement control of the electric telescopic rod 8 on the dynamic conductor 5 is unidirectional, even if the electric telescopic rod 8 retracts, it does not have the ability to control the movement of the dynamic conductor 5, and the dynamic conductor 5 still stays at the moved position. Therefore, even if there is an external attack or virus intrusion into the controller 3 later, it is difficult to restore the connection between the main conductor 4 and the secondary conductor 6 by manipulating the controller 3, that is, it is difficult to restore the connection between the transit verification device and the receiving terminal.

[0052] Please refer to Figure 9 , a side cavity 102 is also formed inside the device body 1. Air flow channels 103 communicating with the inner cavity 101 are formed at both ends of the side cavity 102, and the air flow channels 103 are respectively located on both sides of the inner cavity 101. A flexible sealing sleeve 10 is arranged inside the side cavity 102. The two end ports of the flexible sealing sleeve 10 are respectively fixedly connected to a pair of inner walls of the side cavity 102, and the air flow channels 103 communicate with the inside of the flexible sealing sleeve 10. Air holes 104 communicating with the outside are formed on the inner wall of the side cavity 102. Inert gas is filled in the inner cavity 101, the air holes 104 and the flexible sealing sleeve 10. In the initial state, the dynamic conductor 5 is located between the main conductor 4 and the secondary conductor 6, and the inert gas is located on the side of the dynamic conductor 5 away from the electric telescopic rod 8. When the electric telescopic rod 8 pushes the dynamic conductor 5 to move, the dynamic conductor 5 will squeeze the inert gas, causing it to enter the side cavity 102, and then enter the side of the dynamic conductor 5 close to the electric telescopic rod 8 through the air flow channel 103, that is, located between the main conductor 4 and the secondary conductor 6, which not only realizes the stability of the air pressure, but also the inert gas plays a protective role in the electrical contact among the main conductor 4, the dynamic conductor 5 and the secondary conductor 6. The flexible sealing sleeve 10 is in an incompletely opened state in the initial state, and its function is to maintain the air pressure balance in the inner cavity 101. Since the electric telescopic rod 8 enters the inner cavity 101 and occupies a certain space, the movement of the dynamic conductor 5 will cause an unbalanced air pressure state on both sides of it. At this time, excessive gas can enter the flexible sealing sleeve 10, causing it to expand outwards, and the excess air in the side cavity 102 can be discharged to the outside through the air holes 104.

[0053] A visual inspection rod 9 is provided at one end of the dynamic conductor 5 away from the electric telescopic rod 8. The visual inspection rod 9 includes a rod body 91 and a pair of end heads 92 fixedly connected to both ends of the rod body 91. The rod body 91 movably penetrates through the device body 1 and extends to the outside. The pair of end heads 92 are respectively located inside the inner cavity 101 and the outside. Magnetic coatings are applied to one ends of the pair of rod bodies 91 close to each other, the inner wall of the inner cavity 101 away from the electric telescopic rod 8, and the partial outer end of the device body 1 (that is, Figure 9 the position where the outside end head 92 in Figure 6 contacts the device body 1). Through the setting of the magnetic coating, the visual inspection rod 9 can be in Figure 9 the initial state shown in Figure 7 and Figure 8After being moved by China Mobile, the position can be kept stable and not easily moved randomly, so that the dynamic conductor 5 is not easily moved.

[0054] When the dynamic conductor 5 is pushed by the electric telescopic rod 8, the dynamic conductor 5 will push the visual inspection rod 9 to move outwards together, exposing the rod body 91 to the outside. Without the staff noticing the warning prompt sent by the receiving terminal, it can give a visual reminder to the staff's naked eyes, enabling them to timely discover the abnormal data transmission situation.

[0055] Combined with the current actual requirements, the above-mentioned implementation manner adopted in this application, the protection scope is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.
