[0038] The two embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0039] First embodiment:

[0040] Figure 1 - Figure 9 The security transmission system for image data includes a data transmission server, a data transmission channel connected to the data transmission server, and a central processing unit mounted in the data transmission server, the input end of the central processing unit is connected to a large-volume determination unit and a channel state monitoring unit;

[0041] The input end of the large-volume determination unit is connected to a data input unit for receiving data to be transmitted, and according to the preset parameters, the data is divided into large-volume data and small-volume data, the input end of the channel state monitoring unit is connected to the data transmission channel, for real-time monitoring of the load state of each channel, including but not limited to data throughput, transmission delay, packet loss rate, CPU / memory occupancy rate, etc., by establishing a mapping model of these indicators and channel load (for example, when the load is too high, the delay and temperature will rise), to realize the quantitative perception and prediction of the 'health' of the channel;

[0042] The output end of the central processing unit is connected to:

[0043] A channel scheduling unit for starting the corresponding data transmission channel according to the data classification result;

[0044] The security protection unit is used for real-time security monitoring and active defense of the data transmission channel, and integrates an intrusion detection system (IDS) and an encryption engine. When a DDoS attack, malicious scanning or data tampering is detected, it not only triggers an alarm, but also directly sends a highest-priority instruction to the alternate control unit, which can immediately cut off the connection of the attacked channel and seamlessly switch the data stream to the emergency storage unit. This deep integration of transmission control and security protection realizes the transition from passive defense to active isolation, and is the key to ensuring the continuity of large-volume data during transmission.

[0045] The data buffer queue unit is used for temporarily storing large-volume data to be transmitted.

[0046] The alternate control unit receives signals from the channel state monitoring unit and the security protection unit.

[0047] The data transmission channel includes a large-volume double-channel coupling, the output end of the alternate control unit is connected with a channel switching executor, and the output end of the alternate control unit is also connected with an alternate conversion component arranged between the channel switching executor and the large-volume double-channel. The channel switching executor and the alternate conversion component are coupled with the large-volume double-channel, and are used for controlling the alternate communication between the data buffer queue and different sub-channels in the large-volume double-channel.

[0048] The channel switching executor can be realized in the way of a pure software-defined network (SDN) strategy, has good scalability, and can adapt to different network protocols and hardware environments. The channel switching executor realizes the rapid switching of data packets between different physical or logical channels through the dynamic issuance of flow table rules by a centralized controller.

[0049] The instructions transmitted to the alternate control unit have priorities: the instruction priority of the security protection unit is the highest, the instruction priority of the channel state monitoring unit is the second, and the reference scheduling instruction issued by the central processing unit has the lowest priority. Through the cooperation of the large-volume determination unit, the channel state monitoring unit and the alternate control unit, a three-level linkage mechanism for transmission data is formed, a dynamic and negative feedback intelligent transmission system is constructed, efficient shunting transmission of large-volume and small-volume data can be realized, the stability and integrity of various data transmission are comprehensively guaranteed, and through the dual synergy of software and mechanical control, intelligent allocation and dynamic compensation of large-volume data transmission can be realized. The frequency of alternate conversion of large-volume data transmission can be effectively compensated physically according to the transmission proportion of large-volume data, which improves the transmission efficiency, effectively relieves the channel congestion problem, guarantees the continuity of data transmission, and has the functions of security protection and timely blocking. Through the synergy of active protection, telecommunication signal blocking and mechanical cutting, a solid security barrier is built for the synchronous transmission of multiple large-volume data, and the safety of data is effectively guaranteed.

[0050] Figure 1 and Figure 6 - Figure 9 The data transmission channel also includes a small-volume single channel arranged in parallel with the large-volume double channel, and the output end of the channel scheduling unit is connected with the small-volume single channel and the large-volume double channel respectively;

[0051] The input end of the channel state monitoring unit is connected with the small-volume single channel and the large-volume double channel respectively, and the output end of the data buffer queue unit realizes the alternating transmission conversion function between the sub-channels in the large-volume double channel through the cooperation of the alternating control unit and the channel switching executor. Through the setting of the alternating control unit, the intelligent conversion type transmission path replaces the traditional data direct connection mode, and the precise execution of the channel alternation and dynamic switching function in the large-volume data transmission not only fully guarantees the synchronous transmission demand of multiple large-volume data, but also flexibly allocates the transmission resources through the intelligent double channel adaptation mechanism, effectively solves the bottleneck problem of large-volume data transmission, significantly improves the fluency and continuity of the transmission process, and promotes the efficiency and safety of multiple large-volume data transmission.

[0052] Figure 1 - Figure 5 The alternating conversion assembly includes a physical switcher 1 arranged on the data transmission server, the left end of the physical switcher 1 is connected with a switching lever 3, the upper and lower ends of the switching lever 3 are both fixedly connected with a connecting contact block 2, and the connecting contact block 2 is matched with the sub-channel in the large-volume double channel;

[0053] The physical switcher 1 comprises a flexible isolation box 11 fixedly arranged on the data transmission server, and a pair of electromagnetic control devices 14 symmetrically arranged in up-down direction is fixedly connected to the right inner wall of the flexible isolation box 11. The electromagnetic control devices 14 are coated with a magnetic isolation coating, which effectively avoids the influence of the magnetism of the electromagnetic block on the performance of the data transmission server, and avoids the mutual influence between the two electromagnetic control devices 14. The left end of the electromagnetic control device 14 is fixedly connected with an extension bar 13, the left end of the extension bar 13 extends to the outside of the flexible isolation box 11, and is rotatably connected with a hinge joint 12. The flexible isolation box 11 is also slidably connected with the extension bar 13. Through the cooperation of the hinge joint 12, the electromagnetic control device 14 drives the deformation of the flexible isolation box 11. The flexible isolation box 11 drives the hinge joint 12 to tilt the exchange rotating rod 3. The left end of the hinge joint 12 is hingedly connected with the exchange rotating rod 3. The alternate conversion assembly serves as a physical protection control layer between the channel switching actuator and the large-volume double channel, which can provide further control and compensation for large-volume data transmission process. By using mechanical delay and cutting, it effectively relieves the load pressure of large-volume double channel data transmission, and effectively guarantees the cutting effect of safety protection. The physical switcher 1 can be driven by the electromagnetic control device 14 to produce tilt deformation, and further can drive the exchange rotating rod 3 to tilt. When the exchange rotating rod 3 produces up-down tilt, it can effectively realize the alternate conversion connection of the large-volume double channel, so that the large-volume data in the data buffer queue unit can be effectively transmitted in parallel in the large-volume double channel. The problems of transmission failure, delay fracture or data loss caused by large-volume data transmission are effectively avoided, the continuity of large-volume data transmission is maintained, and further a solid safety guarantee is provided for the synchronous transmission of multiple large-volume data, and the safety of data is effectively guaranteed.

[0054] Figure 1 - Figure 5The upper and lower inner walls of the electromagnetic control 14 are fixedly connected with electromagnetic blocks, the output end of the alternate control unit is connected with the electromagnetic blocks, the alternate control unit can independently control the two electromagnetic controls 14, the alternate control unit can realize the elongation deformation of the electromagnetic control 14 when the two electromagnetic blocks are in repulsion, can realize the stretching deformation of the electromagnetic control 14 when the two electromagnetic blocks are in attraction, and can effectively realize the supporting effect of the elastic isolation box 11 and the hinge joint 12 under the elastic effect of the electromagnetic control 14 when the electromagnetic blocks do not produce magnetic effect. The supporting spring fixedly connected between the upper and lower inner walls of the electromagnetic control 14 is sleeved outside the electromagnetic blocks, which can further guarantee the supporting effect of the electromagnetic control 14 on the elastic isolation box 11 and the hinge joint 12. When it is necessary to cut off the connection between the data buffer queue unit and the large-volume double-channel, the effectiveness of the horizontal cutting of the exchange rotating rod 3 can be effectively guaranteed, the execution efficiency of the alternate conversion is improved, the reliability and response speed when cutting off are guaranteed, and the safety and effectiveness of data transmission are guaranteed.

[0055] Figure 1 and Figure 6 - Figure 9 The output end of the central processing unit is also connected with a safety risk prompting unit and an emergency storage unit. The input end of the emergency storage unit is connected with the data buffer queue unit. The output end of the safety risk prompting unit is connected with an alarm arranged on the data transmission server. The output end of the emergency storage unit is connected with a storage arranged in the data transmission server. The arrangement of the safety risk prompting unit and the emergency storage unit can timely store the untransmitted data when judging that there is a safety risk in the data transmission process and the data transmission is abnormal, so as to avoid data loss and tampering. In addition, the safety risk prompting unit and the emergency storage unit can remind the technical personnel to timely handle the risk or abnormality in the form of warning, so as to reduce the loss caused by the continuous risk.

[0056] Figure 1 and Figure 6 - Figure 9 The input end of the large-volume determination unit is also connected with a judgment parameter setting unit. The input end of the judgment parameter setting unit is connected with a data port arranged on the data transmission server and a cloud database connected with the data transmission server. The arrangement of the judgment parameter setting unit can set and update the judgment standard of the large-volume determination unit, so as to guarantee the accuracy of the large-volume determination after the software and hardware are updated, and to realize the continuous safety guarantee of the large-volume data transmission after the software and hardware are updated. The applicability and accuracy of the large-volume determination standard in different software and hardware environments are effectively improved.

[0057] The technical personnel input the basic range of data size classification judgment into the judgment parameter setting unit through the data port, for example, when the size of a single data is ≤2MB, it is judged as small volume data, and when the size of a single data is >2MB, it is judged as large volume data, then the judgment parameter setting unit transmits the received parameter data to the large volume judgment unit, so that the large volume judgment unit can classify the received data according to the parameter setting and transmit it to the central processing unit; after continuous data replacement and software and hardware update, the data transmission channel is continuously widened and the transmission speed is continuously improved, then the cloud database transmits the updated data size classification judgment basic range of the data transmission server to the judgment parameter setting unit and iterates the data, for example, the size of the small volume data is updated and iterated to ≤5MB, and the size of the large volume data is updated and iterated to >5MB, then the judgment parameter setting unit transmits the updated and iterated data to the large volume judgment unit, so that the large volume judgment unit can re-judge and classify the data after receiving the data subsequently.

[0058] Figure 1 and Figure 6 - Figure 9 The input end of the central processing unit is also connected with a channel threshold value acquisition unit, the input end of the channel threshold value acquisition unit is connected with the channel state monitoring unit and the large volume judgment unit respectively, the channel threshold value acquisition unit can judge the margin of the large volume double channel running space according to the attributes of the large volume data to be transmitted, such as size, quantity and real-time state of the large volume double channel, so as to assist the central processing unit in dynamically regulating and controlling the subsequent large volume data transmission, avoid channel congestion and data packet loss caused by continuous transmission, ensure the integrity and comprehensiveness of multiple large volume data transmission, and also evaluate the safety of the large volume double channel according to the running space, detect whether there is malicious attack data, assist the security protection unit in timely security protection of data transmission, and play an effective security monitoring role.

[0059] Figure 1 and Figure 6 - Figure 9 The output end of the security protection unit is connected with the data transmission channel, and the input end of the security protection unit is also connected with the channel threshold value acquisition unit, the setting of the security protection unit not only can protect the safety of each data transmitted in the data transmission channel, but also can resist the data in time when malicious attack occurs, ensure the reliability and real-time performance of all data transmission, and cooperate with the channel threshold value acquisition unit, when more security protection space and higher security protection level are needed, the connection between the data buffer queue unit and the large volume double channel can be effectively cut off, so as to avoid the continuous entry of subsequent data into the channel and ensure the safety of subsequent data.

[0060] Figure 1 Figure 9 The data input unit inputs each type of data that needs to be transmitted into the bulk quantity determination unit. The bulk quantity determination unit determines each type of data according to the range of the parameter setting, and classifies the bulk quantity data and the small quantity data after the determination, and transmits them to the central processing unit. The central processing unit controls the processing according to the received data. When there is only small quantity data, the small quantity single channel in the data transmission channel is started to work by the channel scheduling unit, and the small quantity data is directly transmitted and output through the small quantity single channel, which improves the efficiency of small quantity data transmission and effectively reduces the energy loss of data transmission and the use loss of the data transmission channel. When there is only bulk quantity data, the bulk quantity double channel in the data transmission channel is started to work by the channel scheduling unit, and the bulk quantity data is transmitted to the data buffer queue unit at the same time. The control instruction of the alternate conversion is transmitted to the alternate conversion control unit, so that the alternate conversion control unit controls the channel switching actuator to alternately connect the data buffer queue unit and the bulk quantity double channel. The transmission pressure is relieved by the alternate conversion transmission of the bulk quantity data in the bulk quantity double channel, which ensures the continuity, integrity and comprehensiveness of the bulk quantity data transmission, and further improves the safety of the bulk quantity data transmission. When there is both bulk quantity data and small quantity data, the small quantity single channel and the bulk quantity double channel in the data transmission channel are started to work by the channel scheduling unit, so that the small quantity data can be transmitted and output in a direct connection manner. At the same time, the central processing unit controls the alternate conversion transmission of the bulk quantity data by the above-mentioned control effect, which effectively plays a role in shunting the data transmission and avoids the occupation of the channel by the data, thereby ensuring the effectiveness of independent shunting transmission and the stability and integrity of various data transmission. In addition, when the data transmission channel is enabled by the transmission channel starting unit in the central processing unit, the safety protection unit is also controlled to start, so as to play a safety protection role on the data transmission channel, thereby effectively avoiding the risk of abnormal access and data tampering during data transmission.

[0061] ​After receiving the alternate conversion instruction transmitted by the central processing unit, the alternate control unit controls the alternate conversion assembly according to the amount and proportion of the required large amount of data transmission. When the amount and proportion of the required large amount of data are small, the electromagnetic blocks in the two electromagnetic control devices 14 are simultaneously energized, so that the corresponding two electromagnetic blocks generate an attractive electromagnetic effect between them. Then, through the cooperation of the electromagnetic control device 14, the extension bar 13 and the hinge joint 12, the elastic isolation box 11 is deformed as a whole, driving the exchange conversion rod 3 and the contact block 2 to move to the right, directly connecting with the sub-channel of the large amount of double-channel, realizing the constant connection between the channel switching actuator and the large amount of double-channel. Then, the alternate control unit controls the channel switching actuator according to the intermittent period or conversion frequency of the alternate conversion, so that the large amount of data in the data buffer queue unit can be distributed according to the channel switching actuator, forming an alternate conversion transmission between the sub-channels of the large amount of double-channel, thereby effectively realizing the intelligent parallel row transmission of the large amount of data, improving the transmission efficiency, relieving the congestion of the data transmission channel, effectively avoiding the problems of transmission failure, delay fracture or data loss caused by large amount of data transmission, and maintaining the continuity of large amount of data transmission.

[0062] When it is judged that the data volume and the proportion of the required large volume data are large, the large volume dual channel cannot effectively perform complete transmission of the large volume data according to the alternate switching frequency of the channel switching actuator, and then the alternate control unit physically intervenes in the control of the alternate switching assembly, and controls the two electromagnetic control units 14 in the elastic isolation box 11 according to the intermittent period or the switching frequency of the alternate switching, first controls the two electromagnetic blocks in the electromagnetic control unit 14 located at the lower side to generate an attractive electromagnetic force, drives the electromagnetic control unit 14 to generate a shrinkage deformation to the right, and keeps the two electromagnetic blocks in the electromagnetic control unit 14 located at the upper side in a constant de-energized state, and then the electromagnetic control unit 14 located at the lower side can drive the elastic isolation box 11 to generate a downward tilt through the extension bar 13 and the hinge joint 12, synchronously drive the exchange shaft 3 to generate a downward tilt, make the lower side on-off contact block 2 connected with the lower side channel in the large volume dual channel, realize the connection of the data buffer queue unit and the channel, and output the large volume data; then the alternate control unit cuts off the current entering the electromagnetic blocks in the electromagnetic control unit 14 located at the lower side, the electromagnetic control unit 14 located at the lower side generates an elongation reset deformation under the elastic action of itself and the cooperation of the supporting spring, at the same time, the two electromagnetic blocks in the electromagnetic control unit 14 located at the upper side are energized to generate an attractive electromagnetic action, and then the electromagnetic control unit 14 located at the upper side generates a shrinkage deformation, and then the electromagnetic control unit 14 located at the upper side can drive the elastic isolation box 11 to generate an upward tilt through the extension bar 13 and the hinge joint 12, synchronously drive the exchange shaft 3 to generate an upward tilt, the lower side on-off contact block 2 is disconnected with the lower side channel in the large volume dual channel, and the upper side on-off contact block 2 is connected with the upper side channel in the large volume dual channel, realizes the connection of the data buffer queue unit and the channel, and outputs the large volume data; such alternate switching control can not only realize the alternate switching channel transmission of the large volume data, but also reduce the running load of the large volume dual channel through physical delay, avoid the performance damage caused by long time full load running.

[0063] In the process of data transmission, the channel state monitoring unit can collect the operating temperature of the small volume single channel and the large volume double channel in the data transmission channel, and then synchronously transmit the state data to the central processing unit, the channel threshold acquisition unit and the alternate conversion control unit. The alternate conversion control unit can determine the operating load state of the large volume double channel according to the operating temperature of each channel, and then compensate the alternate conversion instruction transmitted by the original central processing unit according to the determination result. When the temperature of the sub-channel increases, indicating that the operating load of the sub-channel is large, the sub-channel with normal temperature is continuously transmitted with large volume data, the transmission on time of the sub-channel with normal temperature is increased, and the transmission of the sub-channel with temperature increase is reduced. After the temperature of the sub-channel with temperature increase returns to normal, the alternate conversion instruction transmitted by the original central processing unit is controlled again. While ensuring the large volume data transmission rate, the dynamic control of large volume data transmission is also effectively realized, the transmission mechanism of the large volume double channel is optimized, the problems of transmission failure, delay fracture or data loss caused by large volume data transmission are effectively avoided, and the continuity of large volume data transmission is maintained, thereby providing a solid security guarantee for the synchronous transmission of multiple large volume data and effectively ensuring the security of data.

[0064] When data compensation occurs, the alternate conversion control unit can control the switching frequency of the channel switching executor when it performs alternate conversion transmission of the large volume data in the data buffer queue unit. When the switching frequency of the channel switching executor reaches the limit range, the alternate conversion control unit controls the alternate conversion assembly to realize the delay waiting of large volume data transmission through the frequency control of physical connection and disconnection, so as to avoid the continuous congestion of large volume channel, the performance damage caused by full load state, and the data transmission abnormality and other problems.

[0065] When data compensation occurs, the alternate conversion control unit has controlled the alternate conversion assembly, and then the alternate conversion control unit continues to control the delay of the inclined alternate action of the alternate conversion assembly, so as to relieve the operating pressure of the large volume double channel. The central processing unit can control the transmission to the data buffer queue unit according to the continuous full load operating state of the large volume double channel transmitted by the channel state monitoring unit, relieve the pressure in the data buffer queue unit, and send a risk prompt to the technician through the safety risk prompt unit, so that the technician takes corresponding measures.

[0066] The channel threshold acquisition unit can predict the running load state of each channel of the mass data dual-channel according to the mass data occupancy ratio data transmitted by the mass quantity determination unit, and then judge the channel threshold according to the temperature data fed back by the channel state monitoring unit. When the temperature change is within the predicted range, it means that the alternating conversion transmission function between the mass data dual-channel, the data buffer queue unit and the alternating control unit is effective, and the transmission process of the mass data is stable and continuous. When the temperature change exceeds the predicted range, it means that the mass data dual-channel appears data transmission abnormity; the channel threshold acquisition unit transmits the result of its judgment to the central processing unit. When the central processing unit receives effective mass data transmission, it continues to transmit the mass data to the mass data dual-channel through the data buffer queue unit and the alternating control unit. When it receives abnormal mass data transmission, it first controls the data buffer queue unit to temporarily suspend the continuous transmission of mass data, and sends a control instruction to the security protection unit to make the security protection unit carry out targeted protection on the mass data dual-channel, and to investigate and verify the data in the mass data dual-channel, block abnormal access and data tampering attacks, and ensure the safety of the mass data dual-channel transmission data;

[0067] While the security protection unit is carrying out targeted protection on the mass data dual-channel, the channel threshold acquisition unit can continuously predict and judge the state of the mass data dual-channel. After judging that the running state of the mass data dual-channel is restored, it transmits data to the central processing unit. The central processing unit restores the transmission function of the data buffer queue unit and the general protection function of the security protection unit.

[0068] After judging that the running state of the large-volume double channel is continuously abnormal, data is directly transmitted to the safety protection unit, so that the safety protection unit controls the leveling and cutting of the alternating control unit. The alternating control unit cuts off through the switching actuator, and simultaneously controls the electromagnetic blocks in the two electromagnetic control units 14 to generate repulsive electromagnetic force, which drives the electromagnetic control unit 14 to elongate, directly drives the exchange rotating rod 3 to move up through the elastic isolation box 11, the extension bar 13 and the hinge joint 12, so that the contact block 2 is quickly disconnected from the large-volume double channel, the data transmission is cut off, the continuous spread of malicious attack data is avoided, and the safety of subsequent large-volume data is ensured. The channel threshold acquisition unit simultaneously transmits the continuously abnormal data to the central processing unit, so that the central processing unit stores the large-volume data in the storage through the emergency storage unit, and sends an emergency instruction to the data buffer queue unit, so that the data buffer queue unit can transmit the data in it to the storage through the emergency storage unit, effectively avoiding the problem of data loss caused by subsequent power failure and other abnormal conditions. At the same time, the central processing unit also starts the alarm through the safety risk prompt unit, sends a risk prompt to the technician, prompts the technician to take effective emergency measures in time, and when the data transmission server is re-applied subsequently, the data in the storage can be re-transmitted to the large-volume determination unit for re-determination and transmission.

[0069] Second embodiment:

[0070] Figure 1 - Figure 9 The safety transmission system of image data is shown. The output end of the central processing unit is also connected with a shunt auxiliary unit. The output end of the shunt auxiliary unit is connected with the data buffer queue unit and the small-volume single channel respectively. The shunt auxiliary unit can build a temporary transmission channel between the data buffer queue unit and the small-volume single channel. When the large-volume double channel transmission is saturated, it can also dynamically assist the transmission path of the large-volume data according to the state of the small-volume single channel, realize the synergistic effect of the large-volume double channel and the small-volume single channel, promote the safety and comprehensiveness of the large-volume data transmission, and promote the rate of multiple large-volume data transmission.

[0071] Figure 1 - Figure 9 In the process of data transmission, the channel threshold acquisition unit predicts whether the large-volume double channel appears full load state according to the large-volume data occupation ratio and the state data of the large-volume double channel. When it is judged that the full load state appears, the judgment structure is transmitted to the central processing unit. The central processing unit generates an auxiliary control effect according to whether the small-volume single channel is enabled or not.

[0072] When the small-volume single channel is not enabled, the central processing unit sends control signals to the shunt auxiliary unit, the channel scheduling unit and the data buffer queue unit at the same time, so that the channel scheduling unit starts the small-volume single channel, and the shunt auxiliary unit builds a temporary shunt path between the data buffer queue unit and the small-volume single channel, so that part of the large-volume data in the data buffer queue unit can be transmitted and output through the small-volume single channel, effectively relieving the transmission pressure of the large-volume double channel, ensuring the transmission efficiency and continuity of the large-volume data, and effectively starting the intelligent allocation of the data transmission channel, avoiding the transmission failure, delay lag or data packet loss of the large-volume data;

[0073] When the small-volume single channel has been enabled, the central processing unit transmits control signals to the data buffer queue unit, so that the data buffer queue unit further slows down the transmission of the large-volume data, avoiding the congestion of the large-volume double channel caused by continuous transmission, effectively ensuring the safety and effectiveness of the large-volume data transmission, and the large-volume transmission unit also transmits risk prompt data to the safety risk prompt unit, so that the safety risk prompt unit can start the alarm, so that the technical personnel can handle according to the state of the large-volume data transmission full load at this time, avoiding the performance damage or hardware damage of the data transmission server caused by the continuous accumulation of data.

[0074] In combination with the current actual demand, the protection scope of the above-mentioned embodiments of the present application is not limited to this, various changes made within the knowledge range of those skilled in the art without departing from the concept of the present application still fall within the protection scope of the present application.
