Description

Technical Field

[0001] The present invention relates to the technical field of data transmission, and in particular to a data transmission system and method based on an all-optical driver. Background Art

[0002] In the prior art, the data transmission technology of all-optical drivers mainly includes optical port technology and wavelength division multiplexing technology; optical port technology increases the data transmission capacity by increasing the number of optical ports in the network. Optical ports usually refer to the number of optical paths. However, how to effectively increase the number of optical paths without complicating the network topology and increasing the management burden is a key issue in achieving network quality such as high availability, reliability, security, and manageability. The currently widely used optical port expansion methods include optical division multiplexing technology and optical star distribution technology; wavelength division multiplexing technology refers to the transmission of multiple signals by transmitting optical signals of different wavelengths on the same optical fiber. A wavelength division multiplexing system usually includes a wavelength multiplexer and a wavelength separator. The wavelength multiplexer is responsible for transmitting optical signals of different wavelengths on the same optical fiber, while the wavelength separator is responsible for separating and recombining optical signals of different wavelengths. Through wavelength division multiplexing technology, more data can be transmitted within a limited bandwidth, thereby improving the transmission capacity and efficiency of the optical fiber; optical transmission is a technology for transmitting in the form of optical signals between the sender and the receiver. Commonly used optical transmission equipment includes optical terminals, optical MODEMs, optical transceivers, optical switches, etc. The principle of fiber-optic communication is to convert the transmitted information into electrical signals at the sending end, and then modulate it onto the laser beam emitted by the laser so that the intensity of the light changes with the amplitude of the electrical signal, and then send it out through the optical fiber; at the receiving end, the detector converts the optical signal into an electrical signal after receiving it, and restores the original information after demodulation.

[0003] Chinese Patent Publication No.: CN109857690B discloses an application system of a driver, a driver and a data transmission method, including a master chip, a driver and a slave chip; after the first link training is completed, the driver is used to store the equalization parameters corresponding to each rate in the first link training process in a first storage area, and the data stored in the first storage area will not be lost when the driver performs a reset operation; the driver is also used to receive a reset indication and perform the reset operation according to the reset indication; the master chip and the slave chip are used to perform a re-link training triggered by the reset indication; during the re-link training, the driver is also used to call the equalization parameters, and based on the equalization parameters, the training sequence involved in the re-link training is transparently transmitted to the master chip or the slave chip to complete the re-link training between the master chip and the slave chip. It can be seen that the application system, driver and data transmission method of the driver have the problems of large transmission medium loss during long-distance transmission, reduced security due to electromagnetic interference in communication, reduced stability due to the influence of temperature, humidity and other environmental factors on the transmission network, increased delay in data transmission due to the sorting and modulation method of data set during data transmission, and reduced transmission stability due to the disruption of the order after transmission interruption. Summary of the invention

[0004] To this end, the present invention provides a data transmission system and method based on an all-optical driver, so as to overcome the problems in the prior art such as large transmission medium loss during long-distance transmission, reduced security due to electromagnetic interference in communication, reduced stability due to the influence of the transmission network on the environment such as temperature and humidity, increased delay in data transmission due to the sorting and modulation methods of data set during data transmission, and reduced transmission stability due to the disruption of the order after transmission interruption.

[0005] To achieve the above object, the present invention provides a data transmission system based on an all-optical driver, comprising a data sending end, and further comprising:

[0006] a signal processing unit connected to the data transmitting end and used for converting the data to be transmitted outputted by the data transmitting end and transmitted in the form of an electrical signal into data to be transmitted transmitted in the form of an optical signal, comprising a data classification component for classifying the data to be transmitted according to the data distribution type of the data to be transmitted and an all-optical driver connected to the data classification component and used for converting the classified data to be transmitted into data to be transmitted transmitted in the form of an optical signal;

[0007] The all-optical driver includes a modulator for modulating the classified data to be transmitted onto a corresponding optical carrier and determining a modulation mode of the classified data to be transmitted according to a modulation rate of the data to be transmitted;

[0008] A signal transmission unit connected to the signal processing unit and used to transmit the data to be transmitted to a target object in the form of an optical signal, comprising a channel selection component connected to the modulator and used to determine a transmission channel for the data to be transmitted and a plurality of optical fiber transmission channels connected to the channel selection component;

[0009] A control unit is respectively connected to the signal processing unit and the signal transmission unit, and is used to determine the classification method of the data to be transmitted by the data classification component according to the delay time when transmitting a unit data amount when the data classification component is triggered to run or the channel selection component is triggered to run or the modulator is operated in the modulation mode.

[0010] Furthermore, the all-optical driver further comprises:

[0011] A light source connected to the modulator to generate the optical carrier;

[0012] A driver is connected to the light source and is used to provide operating power for the light source.

[0013] Furthermore, the data classification component is further used to determine the type of each data packet to be transmitted according to the type of the basic data packet in each data packet to be transmitted.

[0014] If all the basic data packets in each data packet to be transmitted are of the same type and are all single-type data packets to be transmitted, the data classification component records the data packet to be transmitted as a single-type data packet to be transmitted;

[0015] If at least one basic data packet in each packet to be transmitted is a composite type basic data packet / there are at least two types of single type basic data packets in all basic data packets of each packet to be transmitted, the data classification component records the packet to be transmitted as a composite type packet to be transmitted;

[0016] The types of the basic data packets include single-type basic data packets and compound-type basic data packets.

[0017] Furthermore, if the data in a single basic data packet has only one type, the basic data packet is recorded as the single-type basic data packet; if the data in a single basic data packet includes at least two types, the basic data packet is recorded as the composite-type basic data packet.

[0018] Furthermore, the channel selection component is connected to the data classification component, and is used for selecting the data packet to be transmitted under the condition that the type of the data packet to be transmitted is the composite type of data packet to be transmitted.

[0019] Determine the transmission channel corresponding to the single-type data packet to be transmitted according to the number of transmission times of the single-type data packets to be transmitted in the signal transmission unit,

[0020] The priority of the corresponding transmission channel is positively correlated with the number of transmission times.

[0021] Further, the modulator is connected to the data classification component to obtain a modulation rate of the composite type data packet to be transmitted under the condition that the type of the data packet to be transmitted is the composite type data packet to be transmitted,

[0022] Among them, if the modulation rate is greater than the preset modulation rate, it is determined that the modulation real-time performance of the data packet to be transmitted does not meet the requirements, and the modulation order of the composite type of data packet to be transmitted is determined according to the proportion of the data volume of a single composite type of data packet to be transmitted.

[0023] Furthermore, the modulator is connected to the data classification component, and is also used to obtain the data volume ratio of the composite type basic data packet in the composite type data packet to be transmitted when the modulation real-time performance of the data packet to be transmitted does not meet the requirements, and sort the data volume ratio from large to small, and the sorting result corresponds to the modulation order of the optical signal of the composite type data packet to be transmitted.

[0024] The data volume ratio is the ratio of the data volume of a single composite type basic data packet to the total data volume of composite type data packets to be transmitted.

[0025] Furthermore, the control unit is connected to the signal transmission unit to obtain the actual time taken by the signal transmission unit to transmit a unit amount of data to the target object when the data classification component is triggered to run or the channel selection component is triggered to run or the modulator is running in the modulation mode, and calculate the delay time for transmitting the unit amount of data according to the actual time taken for transmitting the unit amount of data.

[0026] Among them, if the delay time is greater than the preset delay time, the control unit determines that the real-time performance of the data transmission does not meet the requirements, and controls the data classification component to classify the data to be transmitted according to the classification method; the delay time is the difference between the actual time taken by the signal transmission unit to transmit a unit of data to the target object and the standard time for transmitting a unit of data.

[0027] Furthermore, the classification method is to determine the type of each data packet to be transmitted according to the startup rate of the driver,

[0028] Wherein, if the startup rate is less than the preset rate, it is recorded as a composite type basic data packet;

[0029] If the startup rate is greater than the preset rate, it is recorded as a single type of data packet to be transmitted.

[0030] The present invention also provides a data transmission method based on an all-optical driver, comprising:

[0031] Obtain the delay time of the data to be transmitted when transmitting a unit amount of data;

[0032] Determining whether the real-time performance of data transmission meets the requirements according to the delay duration;

[0033] If the real-time performance of the data transmission does not meet the requirements, the type of the data packet to be transmitted is determined according to the startup rate of the driver;

[0034] If the real-time performance of the data transmission meets the requirements, the data to be transmitted is classified according to the data distribution type of the data to be transmitted,

[0035] The types of the data packets to be transmitted include single-type data packets to be transmitted and composite-type data packets to be transmitted;

[0036] Determining a modulation order of the composite type of data packets to be transmitted according to the modulation rate of the composite type of data packets to be transmitted;

[0037] Modulating the composite type data packet to be transmitted according to the modulation order;

[0038] Determining a transmission channel for a single-type data packet to be transmitted according to the number of transmissions of the single-type data packet to be transmitted;

[0039] The single-type data packet to be transmitted is transmitted according to the transmission channel.

[0040] Compared with the prior art, the beneficial effect of the present invention lies in that the system of the present invention, by setting a signal processing unit, a signal transmission unit and a control unit, realizes the stability and efficiency of data transmission by classifying data, determining the transmission channel through a channel selection component, determining the modulation mode and modulation order through a modulator, and dynamically adjusting the classification method of the data classification component according to the delay time of a unit data volume, because the data transmission medium has large loss during long-distance transmission, the communication is affected by electromagnetic interference and the security is reduced, the transmission network is affected by the environment and the stability is reduced, the data transmission delay is increased due to data sorting and modulation mode, and the order is disrupted after the transmission is interrupted, which leads to the reduction of transmission stability; since in the data transmission process, complex data such as video and image are transmitted in The high number of transmission times and high complexity during the transmission process lead to lower transmission efficiency and lower transmission stability. By giving priority to the transmission channels corresponding to complex data, it is ensured that complex data can obtain faster transmission channels and more efficient modulation methods, thereby achieving improved transmission efficiency; the impact of electromagnetics on data transmission leads to reduced security of data transmission. By using an all-optical driver to transmit data in the form of optical signals in the transmission medium, signal loss during long-distance transmission is reduced, and data integrity is improved. In an all-optical network, data is always transmitted in the form of light from the source to the destination, and only optoelectronic conversion is performed when entering and leaving the network, achieving reduced losses and delays in the conversion process. At the same time, the all-optical driver uses optical fiber as the transmission medium to achieve an increase in data transmission rate.

[0041] Furthermore, the system described in the present invention classifies data according to the format and presentation structure of the data to be transmitted. Since the data is affected by its own format and presentation structure during the transmission process, the number and rate uniformity of data transmission decreases, thereby causing the data transmission efficiency to decrease. By classifying the data before transmitting the data and transmitting the data according to the classified data packets, the efficiency and stability of data transmission are improved.

[0042] Furthermore, the system of the present invention determines the transmission channel. Since the real-time requirement of data transmission requires adjusting the transmission priority of data of different complexity, data with high real-time requirement, such as voice or video stream, requires more rated transmission times. By increasing the priority of the corresponding transmission channel, it is ensured that complex data can be transmitted to the destination quickly and accurately. For data with low real-time requirement, its priority is appropriately lowered to avoid unnecessary interference with the transmission of complex data, thereby improving data transmission efficiency.

[0043] Furthermore, the system of the present invention determines the modulation order. Since the transmission efficiency is reduced due to the large proportion of data in the data type, the data with a large proportion of data is modulated first to reduce congestion in the transmission process and reduce interference with other transmitted data, thereby improving the real-time and smoothness of data transmission.

[0044] Furthermore, the system of the present invention sets a preset delay time. When the data is sorted and modulated, it may cause delays in data transmission or disruption of the order after transmission interruption, resulting in decreased transmission stability. Therefore, the degree of delay is determined based on the average difference in the delay time per unit data volume, and the characteristics of the driver's drive feedback are recorded as the characteristics of the data type so as to directly correspond the characteristics of the data type when transmitted with the feedback characteristics of the driver, thereby saving the link of traversing the identification type and achieving improved transmission efficiency.

[0054] a signal processing unit connected to the data transmitting end and used for converting the data to be transmitted outputted by the data transmitting end and transmitted in the form of an electrical signal into data to be transmitted transmitted in the form of an optical signal, comprising a data classification component for classifying the data to be transmitted according to the data distribution type of the data to be transmitted and an all-optical driver connected to the data classification component and used for converting the classified data to be transmitted into data to be transmitted transmitted in the form of an optical signal;

[0055] The all-optical driver includes a modulator for modulating the classified data to be transmitted onto a corresponding optical carrier and determining a modulation mode of the classified data to be transmitted according to a modulation rate of the data to be transmitted;

[0056] A signal transmission unit connected to the signal processing unit and used to transmit the data to be transmitted to a target object in the form of an optical signal, comprising a channel selection component connected to the modulator and used to determine a transmission channel for the data to be transmitted and a plurality of optical fiber transmission channels connected to the channel selection component;

[0057] A control unit is respectively connected to the signal processing unit and the signal transmission unit, and is used to determine the classification method of the data to be transmitted by the data classification component according to the delay time when transmitting a unit data amount when the data classification component is triggered to run or the channel selection component is triggered to run or the modulator is operated in the modulation mode.

[0058] Specifically, embodiments of the data classification component include Hadoop and Spark.

[0059] Specifically, embodiments of the channel selection component include an electro-optical switch, a magneto-optical switch, a photoelectric converter, an electro-optical converter, and a fiber optic coupler.

[0060] Specifically, the technical parameters of the all-optical driver include: 64-way optical cross-connect backplane for optical direction switching, and the switching time is ≤4ms; support for driving the micro-electromechanical optocoupler module kit and the 64-way optical cross-connect backplane to switch the optical fiber signal from any port to any other port.

[0061] In practice, the system of the present invention is provided with a signal processing unit, a signal transmission unit and a control unit. Since the data transmission medium has large losses during long-distance transmission, the communication is subject to electromagnetic interference, resulting in reduced security, the transmission network is affected by the environment, resulting in reduced stability, the data sorting and modulation method leads to increased data transmission delay, and the order is disrupted after the transmission is interrupted, resulting in reduced transmission stability, the stability and efficiency of data transmission are achieved by classifying the data, determining the transmission channel through the channel selection component, determining the modulation method and modulation order through the modulator, and dynamically adjusting the classification method of the data classification component according to the delay time of the unit data volume; since the complex data such as video and image are transmitted during the transmission process The high number of times and complexity lead to lower transmission efficiency and lower transmission stability. By giving priority to the transmission channels corresponding to complex data, we ensure that complex data can obtain faster transmission channels and more efficient modulation methods, thereby improving transmission efficiency. The impact of electromagnetics on data transmission leads to reduced security of data transmission. By using an all-optical driver to transmit data in the form of optical signals in the transmission medium, signal loss during long-distance transmission is reduced, and data integrity is improved. In an all-optical network, data is always transmitted in the form of light from the source to the destination, and only optoelectronic conversion is performed when entering and leaving the network, thereby reducing losses and delays in the conversion process. At the same time, the all-optical driver uses optical fiber as the transmission medium to increase the data transmission rate.

[0062] Specifically, the all-optical driver further includes:

[0063] A light source connected to the modulator to generate the optical carrier;

[0064] A driver is connected to the light source and is used to provide operating power for the light source.

[0065] Specifically, the data classification component is further used to determine the type of each data packet to be transmitted according to the type of the basic data packet in each data packet to be transmitted.

[0066] If all the basic data packets in each data packet to be transmitted are of the same type and are all single-type data packets to be transmitted, the data classification component records the data packet to be transmitted as a single-type data packet to be transmitted;

[0067] If at least one basic data packet in each packet to be transmitted is a composite type basic data packet / there are at least two types of single type basic data packets in all basic data packets of each packet to be transmitted, the data classification component records the packet to be transmitted as a composite type packet to be transmitted;

[0068] The types of the basic data packets include single-type basic data packets and compound-type basic data packets.

[0069] In implementation, the system of the present invention classifies data according to the format and presentation structure of the data to be transmitted. Since the data is affected by its own format and presentation structure during the transmission process, the number and rate uniformity of data transmission decreases, thereby causing the data transmission efficiency to decrease. By classifying the data before transmitting the data and transmitting it according to the classified data packets, the efficiency and stability of data transmission are improved.

[0070] Specifically, if the data in a single basic data packet has only one type, the basic data packet is recorded as the single-type basic data packet; if the data in a single basic data packet includes at least two types, the basic data packet is recorded as the composite-type basic data packet.

[0071] Specifically, the channel selection component is connected to the data classification component to select the data packet to be transmitted under the condition that the type of the data packet to be transmitted is the composite type of data packet to be transmitted.

[0072] Determine the transmission channel corresponding to the single-type data packet to be transmitted according to the number of transmission times of the single-type data packets to be transmitted in the signal transmission unit,

[0073] The priority of the corresponding transmission channel is positively correlated with the number of transmission times.

[0074] Specifically, the types of data to be transmitted include video, pictures, and text.

[0075] During implementation, the system of the present invention determines the corresponding transmission channel. Since the real-time requirement of data transmission requires adjusting the transmission priority of data of different complexity, data with high real-time requirement, such as voice or video stream, requires more rated transmission times. By increasing the priority of the corresponding transmission channel, it is ensured that complex data can be transmitted to the destination quickly and accurately. For data with low real-time requirement, its priority is appropriately lowered to avoid unnecessary interference with the transmission of complex data, thereby improving data transmission efficiency.

[0076] Specifically, the modulator is connected to the data classification component to obtain the modulation rate of the composite type data packet to be transmitted under the condition that the type of the data packet to be transmitted is the composite type data packet to be transmitted,

[0077] Among them, if the modulation rate is greater than the preset modulation rate, it is determined that the modulation real-time performance of the data packet to be transmitted does not meet the requirements, and the modulation order of the composite type of data packet to be transmitted is determined according to the proportion of the data volume of a single composite type of data packet to be transmitted.

[0078] Specifically, the modulation rate is the ratio of the amount of data packets to be transmitted modulated by the modulator per unit time to the unit time.

[0079] Specifically, the general value range of the preset modulation rate is [9.34 GHz, 9.46 GHz], and the preferred embodiment of the preset modulation rate is 9.4 GHz.

[0080] Specifically, the modulator is connected to the data classification component, and is also used to obtain the data volume ratio of the composite type basic data packet in the composite type data packet to be transmitted when the modulation real-time performance of the data packet to be transmitted does not meet the requirements, and sort the data volume ratio from large to small, and the sorting result corresponds to the modulation order of the optical signal of the composite type data packet to be transmitted.

[0081] The data volume ratio is the ratio of the data volume of a single composite type basic data packet to the total data volume of composite type data packets to be transmitted.

[0082] During implementation, the system of the present invention determines the modulation order. Since the transmission efficiency is reduced due to the large proportion of data in the type of data, the data with a large proportion of data is modulated first to reduce congestion in the transmission process and reduce interference with other transmitted data, thereby improving the real-time and smoothness of data transmission.

[0083] Specifically, the control unit is connected to the signal transmission unit to obtain the actual time taken by the signal transmission unit to transmit a unit amount of data to the target object when the data classification component is triggered to run, the channel selection component is triggered to run, or the modulator is running in the modulation mode, and calculate the delay time for transmitting the unit amount of data according to the actual time taken for transmitting the unit amount of data.

[0084] Among them, if the delay time is greater than the preset delay time, the control unit determines that the real-time performance of the data transmission does not meet the requirements, and controls the data classification component to classify the data to be transmitted according to the classification method; the delay time is the difference between the actual time taken by the signal transmission unit to transmit a unit of data to the target object and the standard time for transmitting a unit of data.

[0085] Specifically, the general value range of the standard duration is [400 μs, 500 μs], and the preferred embodiment of the standard duration is 420 μs.

[0086] Specifically, the general value range of the preset delay time is [20μs, 30μs].

[0087] Preferably, the preferred embodiment of the preset delay time length is 26 μs.

[0088] Specifically, the classification method is to determine the type of each data packet to be transmitted according to the startup rate of the driver,

[0089] Wherein, if the startup rate is less than the preset rate, it is recorded as a composite type basic data packet;

[0090] If the startup rate is greater than the preset rate, it is recorded as a single type of data packet to be transmitted.

[0091] Specifically, the startup rate is the speed at which the drive can read data after it starts.

[0092] Specifically, the general value range of the preset rate is [100MB / s, 160MB / s].

[0093] Preferably, the preferred embodiment of the preset rate is 120 MB / s.

[0094] In implementation, the system of the present invention sets a preset delay time. When setting the data sorting and modulation method, it may cause delays in data transmission or disrupt the order after transmission interruption, resulting in decreased transmission stability. Therefore, the degree of delay is determined based on the average difference in the delay time per unit data volume, and the characteristics of the driver's drive feedback are recorded as the characteristics of the data type to directly correspond the characteristics of the data type when transmitted with the feedback characteristics of the driver, thereby saving the link of traversing the identification type and achieving improved transmission efficiency.

[0098] If the real-time performance of the data transmission does not meet the requirements, the type of the data packet to be transmitted is determined according to the startup rate of the driver;

[0099] If the real-time performance of the data transmission meets the requirements, the data to be transmitted is classified according to the data distribution type of the data to be transmitted,
