[0036] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0037] like Figure 1-Figure 2 As shown, an optical module provided in an embodiment of the present application includes: a microprocessor and a plurality of different types of interfaces on the microprocessor.

[0038] The first side surface of the microprocessor is provided with a first optical transceiver interface 1 - 1 , a first optical fiber bus 2 and a second optical fiber bus 3 .

[0039] The second side of the microprocessor is provided with an optical module side electrical-electrical interface 1-2; the optical module side electrical-electrical interface 1-2 is used to connect the optical module electrical-electrical attachment 4, and, through the machine side electrical-electrical interface 5, connect the machine side processor 5-1 and the power supply. The machine side processor is a machine side MCU, MPU or FPGA.

[0040] The third side of the microprocessor is provided with a second optical transceiver interface 1-3 and a third optical fiber bus 6; the first optical transceiver interface 1-1 and the second optical transceiver interface 1-3 are equipped with optical transceiver circuits, both of which are used to connect the optical-optical interface 7 of the optical module, and the optical transceiver circuit is the IO external optical module side optical transceiver circuit 1-5; the first optical fiber bus 2 and the second optical fiber bus 3 are used for the main channel, and the main channel is for signal transmission between optical modules; the third optical fiber bus 6 is used to connect the optical-optical interface of the machine within the distance range of the optical module.

[0041] The optical-optical interface of the optical module (i.e., the first optical fiber bus 2 and the second optical fiber bus 3) is used for the main channel, which is convenient for fast transmission of information and can realize addressed transmission, avoid broadcast signal interference, and occupy a small space-time communication space.

[0042] The present invention and the optical fiber bus are applied in industrial control environments, and are easy to implement hand-in-hand integrated wiring, realize all-optical topology and all-digital communication, are anti-interference, anti-corrosion, explosion-proof, have excellent bandwidth, high communication rate, long distance, no common ground interference between machines, have good isolation, and can eliminate safety isolation fences.

Among them, the first optical transceiver interface 1-1 and the second optical transceiver interface 1-3 are built-in optical module side photoelectric transceiver conversion circuit.

[0044] In an exemplary embodiment, the shape structure of the optical module is designed based on the application scenario of the field integrated wiring; the shape structure of the optical module includes a T-shaped 8 (such as Figure 3-Figure 4 As shown), H-shaped 9 (as Figure 5-Figure 6 As shown), L-shaped 10 (as Figure 7-Figure 8 as shown) and the cross 11 (as shown Figure 9-10 shown).

[0045] Among them, ①T shape is used for bidirectional wiring; ②H shape is used for unidirectional wiring; ③L shape is used for horizontal and vertical wiring; ④cross shape is used for four-directional wiring.

[0046] The structure of the optical module in the prior art is mostly a small rectangular parallelepiped, with an optical port at one end and an electrical interface at the other end. It is usually plugged in (a few are welded) in the machine to which it belongs. The machine main controller powers the optical module and sends and receives signals through the electrical interface. A certain space must be left outside the optical port for the curvature of the optical fiber. The optical module cannot be separated from the machine, which brings inconvenience to the design and installation of the machine and has requirements for the space where the machine is located. The various external structures of the optical module provided in this application fully consider the application scenarios of on-site integrated wiring, and there is no need to reserve space for the curvature of the optical fiber at the optical port end of the optical module.

[0047] In an exemplary embodiment, Figure 11-Figure 12 As shown, the optical module electrical-electrical accessory 4 specifically includes: an electrical-electrical accessory machine side interface 4-1 of the same specification as the electrical-electrical interface 1-2 on the optical module side and an electrical-electrical accessory optical module side pin 4-3 of the same specification as the electrical-electrical interface 1-2 on the optical module side; the electrical-electrical accessory machine side interface 4-1 is used to connect the optical module; the electrical-electrical accessory optical module side pin 4-3 is used to connect the machine; a shielded metal wire 4-2 is provided between the electrical-electrical accessory machine side interface 4-1 and the electrical-electrical accessory optical module side pin 4-3.

[0048] The electrical-electrical interface 1-2 on the optical module side can be directly connected to the electrical-electrical accessory machine side interface 4-1 by plugging and unplugging. It is used for machine equipment with space and interface types that can be directly plugged and unplugged. It is the focus of the solution of the present invention, the main method to realize and change the user's lack of communication interface, bus and protocol selection rights, and the necessary guarantee for the efficient implementation of the all-optical redundant topology structure. It is one of the foundations of the intelligent architecture.

[0049] In an exemplary embodiment, Fig.13 As shown, the optical module electro-optical accessory 7 specifically includes: an electro-optical transceiver 7-2 on the optical module side and an electro-optical transceiver 7-3 on the meter side; the electro-optical transceiver 7-2 on the optical module side includes a docking fixing nut 7-4, an optical module side light emitting tube 7-5 and an optical module side photosensitive receiving tube 7-6; the electro-optical transceiver on the meter side includes an instrument side light emitting tube 7-8 and an instrument side photosensitive receiving tube 7-7; the optical module side light emitting tube 7-5 corresponds to the instrument side photosensitive receiving tube 7-7; the instrument side light emitting tube 7-8 corresponds to the optical module side photosensitive receiving tube 7-6; the docking fixing nut 7-4 is used to dock the electro-optical transceiver 7-2 on the optical module side and the electro-optical transceiver 7-3 on the meter side. The optical module side light emitting tube 7-5 and the instrument side light emitting tube 7-8 are LD emitting tubes or LED emitting tubes. The meter is connected to the instrument side electro-optical transceiver 7-3 through a metal wire 7-1.

[0050] The electro-optical interface of the optical module connects the electro-optical accessory 7 of the optical module and the electro-optical accessory on the instrument side, and is used to connect instruments and meters that are small in size, have a small amount of data, have a small power reserve, and are not suitable for directly plugging and unplugging the optical module. The electro-optical interface of the optical module is connected to the instrument through the electro-optical accessory 7 of the optical module to realize signal conversion. The optical transceiver device of the electro-optical accessory 7 of the optical module effectively realizes signal isolation, and the connecting wires are conducive to wiring at any angle at close range; the electro-optical interface of the optical module is connected to the instrument through the electro-optical accessory on the instrument side.

[0051] In an exemplary embodiment, the microprocessor is a microprocessor or FPGA 1-6 having a DMA circuit; the microprocessor includes a plurality of DMA channels 1-4. The DMA channels 1-4 are DMA channels of the microprocessor or FPGA.

[0052] In an exemplary embodiment, Fig.14 As shown, the microprocessor is also provided with a four-core 0 / 1 transceiver interface 17, an eight-core TCP / IP transceiver interface 18, and a ten-core 0 / 9 transceiver interface 19.

[0053] This application is based on the circuit structure and appearance structure of the optical module. Through pre-programming, remote and / or protocol control, it can instantly select the optical module that defines the communication bus pins, interfaces and protocols, solve problems such as independent technology communication protocol standards and interface standard methods, improve communication bandwidth and rate, and realize multi-protocol label exchange and multi-modal communication.

[0054] The optical module with optical-optical, optical-electrical, and electrical-electrical interfaces provided in the present application solves the problems of the main communication carrier composed of optical modules and optical fibers in industrial environments, the method of connecting machines, equipment, instruments and systems with full digital communications, isolation, common ground, anti-interference, corrosion resistance, explosion-proof, long transmission distance, and low latency in industrial environments.

[0055] The optical modules with various shapes and structures provided in this application solve the problems of optical fiber wiring and the need to reserve optical fiber curvature space outside the optical port. The optical modules and accessories that can be separated from the machine and equipment solve the problems of the need to separate the optical module from the machine in extreme environments, the working power supply of the optical module, and the need to connect one optical module to multiple machines, equipment, instruments, etc.

[0056] like Fig.15As shown, another embodiment of the present application provides a fully optical redundant topology structure based on optical modules, including: multiple optical modules shown above; multiple optical modules are connected through two or more optical fiber buses; the optical fiber bus includes a first optical fiber bus 2, a second optical fiber bus 3 and a third optical fiber bus 6; the first optical fiber bus 2 and the second optical fiber bus 3 are used for the main channel, and the main channel is the signal transmission between the optical modules; the third optical fiber bus 6 is used to connect the optical-optical interface of the machine within the distance range of the optical module; each optical fiber bus is processed in parallel and communicates independently, even if one optical fiber bus is damaged or fails, the optical buses of other channels can still operate normally, and data is not easily lost; in addition, the multiple optical fiber buses form a redundant topology structure, which can compare the data of the multiple optical buses to determine whether the transmitted data is accurate, thereby improving the accuracy of the transmitted data.

[0057] The optical module side electrical-electrical interface 1 - 2 of the optical module is used to connect to the optical module electrical-electrical accessory 4 , and, through the machine side electrical-electrical interface 5 , to connect to the machine side processor and power supply.

[0058] The electro-optical interface of the optical module is used to connect the electro-optical accessories of the optical module and the electro-optical accessories on the instrument side.

[0059] The first optical transceiver interface 1 - 1 and the second optical transceiver interface 1 - 3 of the optical module have built-in optical transceiver circuits, and are both used to connect the optical-optical interfaces of the optical module.

[0060] Fig.15 The system also includes intelligent equipment 12, a meter 13, an instrument 14, a host computer 15 and a host computer 2 16; wherein the meter 13 is provided with a meter-side electro-optical interface 13-1.

[0061] In industrial control environments, although some machines currently use optical buses, they are only alternative applications to existing technology buses and have not been systematically studied and widely used. They still follow the master-slave broadcast communication method of the existing protocol and fail to give full play to the interactive communication advantages of optical modules. In addition, their optical buses and interfaces are fixed and cannot be changed instantly on site.

[0062] For a long time, the control and communication between people and machines have been hierarchical control systems, which have obvious centralized, multi-level, and master-slave characteristics, with closed-loop feedback at the same level. The topology structures are single or combined bus, ring, tree, star, and mesh topologies. Currently, only the mesh topology structure achieves redundancy, and the others all achieve hot redundancy (also known as hot standby) in parts known to be prone to failure. It is local redundancy, and message sending is broadcast. The communication bus, interface, and protocol are all imported technologies. Due to the node restriction characteristics of the hierarchical control system, the improvement of the level of intelligence and emergency management is seriously affected.

[0063] For a long time, when users purchase machines, equipment, instruments, systems, etc. involving communications, the communication bus, interface and protocol are all determined by the manufacturer. Different manufacturers provide different buses, interfaces and protocols. Not only do users have almost no choice, but it also brings many disadvantages to construction, transformation and operation and maintenance during the system integration process. It is also the main factor that restricts and hinders the improvement of productivity.

[0064] The present application provides a fully optical redundant topology structure based on the above-mentioned innovative optical modules, which solves the digital and intelligent architecture of machines, equipment, instruments and systems, and solves the requirements of preventive plan design, intelligent handling of emergencies, and remedial emergency control for emergency management.

[0065] The all-optical redundant topology based on optical modules, the optical fiber bus and custom bus, interface and protocol based on optical modules have a very high industrial information security index. It can map machines, equipment, instruments and systems to efficiently realize intelligent architecture, and enable large industrial Internet systems to be highly intelligent. It can realize the unified bus, interface, protocol and its standards of the all-optical topology of machines, equipment, instruments and systems, and thus realize all-digital communication.

[0066] This application can also unify the fieldbus protocol to give users the right to choose; enable the iteration and synchronization of machines, equipment, systems and ecological AI; enable the digitalization and intelligence of industrial manufacturing, and the construction of fast and efficient construction, and realize industrialization and standardization.

[0067] like Fig.15 As shown, taking two buses as an example, the all-optical redundant topology is connected via more than two buses, more than two working power supplies and more than two channels of the machine. Therefore, when an emergency occurs, control can be achieved through other channels, thereby achieving emergency management control; achieving new quality productivity and high-quality sustainable development; and achieving the coexistence of centralization and decentralization.

[0068] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] This article uses specific examples to illustrate the principles and implementation methods of this application. The description of the above embodiments is only used to help understand the method and core ideas of this application. At the same time, for those skilled in the art, according to the ideas of this application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting this application.
