The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it is obvious that the embodiments described below are some, not all embodiments of the present invention.
Referring to fig. 1, a communication terminal based on an all-optical IP address provided in an embodiment of the present invention includes a light source module, a circulator, an all-optical IP address module, a photoelectric processing module, a light source control module, and a main control module. The light source module is used for outputting different pulse light waves; the circulator comprises a first port, a second port and a third port, and the first port is connected with the output end of the light source module; the input end of the all-optical IP address module is connected with the third port and used for reflecting or transmitting pulse light waves to perform all-optical IP address identification and communication; the input end of the photoelectric processing module is connected with the output end of the all-optical IP address module; the light source control module is electrically connected with the light source module and used for adjusting the pulse light waves output by the light source module; the main control module is electrically connected with the light source control module and the photoelectric processing module respectively.
Specifically, as shown in fig. 1, under the control of the main control module, the light source control module may adjust the light source module, specifically, may control the light source module to be turned on and off, and may control the magnitude of the power supply current of the light source module to adjust the light emitting power of the light source module, so as to output different pulse light waves, such as identification pulse light waves and communication pulse light waves. The all-optical IP address module of the receiving side communication terminal reflects the identification pulse light waves and transmits the identification pulse light waves back to the circulator of the transmitting side communication terminal, and the photoelectric processing module of the transmitting side communication terminal performs photoelectric conversion on the reflected identification pulse light waves and then transmits the converted identification pulse light waves to the main control module for analysis, so that the identification of the all-optical IP address of the receiving side communication terminal is completed. The communication pulse light waves are transmitted to the circulator and transmitted to the communication terminal at the receiving side, the all-optical IP address module of the communication terminal at the receiving side transmits and reflects the communication pulse light waves, the transmitted communication pulse light waves are subjected to photoelectric conversion by the photoelectric processing module at the receiving side and then transmitted to the main control module for analysis, so that double-side communication is completed, the reflected communication pulse light waves are transmitted back to the circulator at the communication terminal at the transmitting side, the photoelectric processing module at the communication terminal at the transmitting side performs photoelectric conversion on the reflected communication pulse light waves and then transmitted to the main control module for analysis, and therefore communication verification is completed.
It should be noted that, with continuing reference to fig. 2 and 3, fig. 2 and 3 are timing diagrams of the identification pulsed lightwave and the communication pulsed lightwave, respectively. It will be appreciated that the identification pulsed light waves are used only for identification of all-optical IP addresses, which are not used for transmission of communication data, and therefore need to be distinguished from the communication pulsed light waves used for transmission of data. Specifically, discrimination can be achieved by setting the pulse width of the identification pulse light wave to be larger than the pulse width of the communication pulse light wave. When the address bit of the communication pulse light wave is matched with the all-optical IP address of the all-optical IP address module at the receiving side, the communication pulse light wave can be transmitted by the all-optical IP address module, so that the data bit is analyzed after photoelectric conversion, and communication is realized. Therefore, the identification of the all-optical IP address is carried out by emitting the identification pulse light wave, so that the light source module can emit the communication pulse light wave based on the obtained all-optical IP address, and finally, the communication is realized. Further, when all the address bits are defined to be 1, the communication terminal on the transmitting side communicates with all the communication terminals on the receiving side connected thereto, and when all the address bits are not defined to be 1, specified communication is performed based on the all-optical IP address corresponding to the address bits. In some embodiments, the communication pulsed light wave further comprises a start flag and an end flag for identifying the start and end of processing the segment of the pulsed light wave from the address bit to the data bit in the communication pulsed light wave.
In this embodiment, the light source control module is used to adjust the light source module to output different pulsed light waves, so that when the communication terminal of the embodiment of the present invention is used as a transmitting side, the communication terminal can transmit identification pulsed light waves and communication pulsed light waves for identification of all-optical IP addresses and both-side communication; the identification pulse light wave and the communication pulse light wave which are sent from the opposite side are reflected or transmitted by the all-optical IP address module, so that when the communication terminal of the embodiment of the invention is used as a receiving side, the identification of the all-optical IP address and the transmission of communication data can be completed. Therefore, for the communication terminal based on the all-optical IP address in the embodiment of the invention, the communication of all-optical IP addressing is realized by using the wavelength of the single light source, the traditional communication mode of IP address identification depending on electric signals is improved, and the light wave utilization rate in communication is improved.
In some embodiments, as shown in fig. 4, the all-optical IP address module is an optical fiber all-optical IP address module, which is made by setting multiple wavelength identifiers on an optical fiber.
In particular, referring to fig. 4, it can be understood that, for the communication terminal according to the embodiment of the present invention, optical modules or elements thereof are connected by optical fibers, and therefore, the all-optical IP address module may employ a method of directly processing a plurality of wavelength identifiers on optical fibers, which are not spaced apart by a certain distance, that is, an optical fiber all-optical IP address module. Specifically, the wavelength identifier may be a fiber grating, a reflective film (sheet), a transmissive film (sheet), or a silicon-based line grating. Because the existing products of the reflecting film (sheet) and the transmitting film (sheet) have larger wavelength width and are not suitable for the existing application scene, the embodiment adopts the fiber grating, can be directly engraved on the optical fiber and is butted with the optical fiber material product, the cost is relatively low, and the fiber grating comprises a reflecting fiber grating, a transmitting fiber grating, a phase fiber grating and the like.
In some embodiments, as shown in fig. 5, the all-optical IP address module employs a core all-optical IP address module, which is made by disposing a plurality of wavelength labels on a silicon substrate.
Specifically, referring to fig. 5, it can be understood that the wavelength identifier in this embodiment uses a silicon-based etched grating, and the wavelength identifier is etched by performing an etching technique on a circuit board such as a silicon substrate, that is, the core-type all-optical IP address module. Specifically, the core-type all-optical IP address module is etched on the circuit board, and the light source module, the photoelectric processing module, the circulator and the like in the communication terminal can also be completely etched on the circuit board, so that all-optical IP chipization is realized. However, the core all-optical IP address module is required to be higher in precision and higher in cost, and therefore, the fiber all-optical IP address module is preferably used.
It should be noted that, wavelength identifiers are used for labeling, the distance between adjacent wavelength identifiers may be used as a coding basis, and j may specifically adopt a binary system or a decimal system. For example, the binary system is based on the reference pitch L, and is 0 when the set spacing distance is less than 1.5 × L, and is 1 when the set spacing distance is greater than 1.5 × L; the decimal is based on the reference pitch L and is decimal by a multiple of 1.5 × L, for example, the pitch is 8 × 1.5 × L to 8.5 × 1.5 × L.
In some embodiments, as shown in fig. 1, the photoelectric processing module includes a photoelectric conversion unit and an analog-to-digital conversion unit. The input end of the photoelectric conversion unit is connected with the output end of the all-optical IP address module, and the photoelectric conversion unit is used for converting optical signals into electric signals; the input end of the analog-to-digital conversion unit is connected with the output end of the photoelectric conversion unit, and the output end of the analog-to-digital conversion unit is electrically connected with the main control module.
Specifically, referring to fig. 1, the photoelectric processing module may adopt a combination of a photoelectric conversion unit and an analog-to-digital conversion unit, specifically, a reflected pulse light wave is processed by the photoelectric conversion unit, so as to convert an optical signal into an analog electrical signal, and further processed by the analog-to-digital conversion unit, so as to convert the analog electrical signal into a digital signal, and the digital signal is transmitted to the main control module to be analyzed. Specifically, the photoelectric conversion unit may implement photoelectric conversion using a PIN photodiode, and may also implement photoelectric conversion using an Avalanche Photodiode (APD). The core processor of the main control module can adopt a single chip microcomputer, a DSP or an ARM, and particularly can use an STM32 series processor.
In addition, referring to fig. 6, an embodiment of the present invention further provides a communication system based on an all-optical IP address, including multiple optical splitters and a communication master station. The plurality of light splitters are connected in series; the communication master station is connected with the optical splitter at one end of the plurality of optical splitters which are connected in series, and adopts the communication terminal based on the all-optical IP address according to the embodiment of the invention; the communication substations are respectively connected with the optical splitters in a one-to-one correspondence manner, each communication substation is respectively used for communicating with the communication master station, and each communication substation adopts the communication terminal based on the all-optical IP address.
Specifically, referring to fig. 6, a schematic structural diagram of a communication system based on an all-optical IP address according to an embodiment of the present invention is shown. It will be appreciated that a plurality of splitters are utilized in series so that serial communication can be established between the communication master station and the plurality of communication substations. Specifically, the communication master station and the communication substations both adopt the communication terminal based on the all-optical IP address of the embodiment of the present invention, so that the light source module of the communication master station can emit identification pulsed light waves, thereby completing all-optical IP address identification for each communication substation, and compiling an all-optical IP address routing table; furthermore, the light source module of the communication master station can also send out communication pulse light waves, so that the communication with one or more communication sub-stations of the target all-optical IP address is completed. Since serial communication is used, only the communication master station and the communication slave station can establish communication, but the communication slave station cannot establish communication. In some embodiments, the optical splitter may employ an optical coupler.
It can be understood that the communication terminals according to the embodiments of the present invention are used as the communication master station and the communication slave station in the communication system according to the embodiments of the present invention, so that two-party communication can be established. When the communication master station is used as a transmitting side, the light source control module is used for adjusting the light source module to output different pulse light waves, so that the identification pulse light waves and the communication pulse light waves can be transmitted for identification of all-optical IP addresses and communication between the two parties; when the communication sub station is used as a receiving side, the identification pulse light wave and the communication pulse light wave which are transmitted from the opposite side are reflected or transmitted by the all-optical IP address module, so that the identification of the all-optical IP address and the transmission of communication data can be completed. Therefore, for the communication system based on the all-optical IP address in the embodiment of the invention, the communication of all-optical IP addressing is realized by using the wavelength of the single light source, the traditional communication mode of IP address identification depending on electric signals is improved, and the light wave utilization rate in communication is improved.
In addition, as shown in fig. 7, an embodiment of the present invention further provides a communication method based on an all-optical IP address, which is applied to a communication system based on an all-optical IP address in the embodiment of the present invention, and includes the following steps:
all-optical IP address recognition is carried out on all-optical IP address modules of a plurality of communication substations by utilizing a light source module and a light source control module of a communication master station so as to obtain an all-optical IP address routing table, wherein the all-optical IP address routing table consists of all-optical IP addresses of all communication substations;
and establishing a communication link between the communication substation corresponding to the target all-optical IP address and the communication master station according to the target all-optical IP address and the all-optical IP address routing table.

It can be understood that the all-optical IP address recognition of each communication substation is completed by reflecting and recognizing the pulsed light waves to the all-optical IP address module of each communication substation through the light source module of the communication master station, and thus a routing table including all-optical IP addresses of all communication substations can be compiled.

and the circulator of the communication master station receives the reflected first communication pulse light wave and is processed by the photoelectric processing module to complete communication verification.
It can be understood that, when the communication master station is used as a transmitting side, the first communication pulsed light wave transmitted by the light source module of the communication master station is transmitted by the all-optical IP address module of the target communication substation on the receiving side, that is, the target communication substation receives communication data to complete communication; and on the other hand, the data is reflected by an all-optical IP address module of the target communication substation at the receiving side, namely the communication master station determines that the communication data is transmitted to the receiving side, so that the communication verification is realized.
In some embodiments, the method comprises the following steps:
a light source module of the target communication substation outputs a second communication pulse light wave, the second communication pulse light wave is transmitted to an all-optical IP address module of the communication master station through a circulator to be reflected and transmitted, and the transmitted second communication pulse light wave is analyzed by a photoelectric processing module of the communication master station;
