[0026] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1 -Attached Figure 7 It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0027] This application proposes an industrial-scale post-processing plant telephone dispatch system, which adopts the following technical solutions:

[0028] An industrial environment redundant dispatch telephone system includes a telephone network, wherein the telephone network includes: a main dispatch network and a redundant dispatch network connected to each other;

[0029] The main dispatching network includes a star topology, a tree topology, a mesh topology, a bus topology and / or a ring topology; the telephone network is necessary in an industrial-scale post-processing plant. The purpose of the dispatching telephone system is to implement a system for dispatching workers at different positions under different levels and different working conditions in an industrial-scale post-processing plant. Unlike wireless networks, wired telephone networks have a more stable working state and are not affected by the instability of wireless network base stations. For example, if there is a problem with the power supply system of a wireless network base station, the communication nodes within the coverage of the wireless network base station cannot work normally. The various topological structures of the main dispatching network are actually changed according to different plant site conditions, process requirements, plant conditions and dispatching management requirements. According to the actual plant site conditions, the structure of the main dispatching network can also be combined, that is, at least two topological structures can be combined according to actual needs.

[0030] The redundant dispatch network is used to actively make up for the lack of the main dispatch network function when part or all of the main dispatch network fails, so as to realize the dispatch function of the redundant dispatch telephone system in the industrial environment. There are also many topological structures for the realization of redundant dispatch network, but they are all designed for different possible failures of the main dispatch network.

[0031] Preferably, Figure 1As shown, the black solid circle is the main node of the main dispatching network; the gray solid circle is the main node of the redundant dispatching network; the white solid circle is the sub-node of the main dispatching network and the sub-node of the redundant dispatching network. The solid line is the connection between the main node and the sub-node in the main dispatching network, and the dotted line is the connection between the main node and the sub-node in the redundant dispatching network. When the main dispatching network is a star topology structure, the redundant dispatching network includes: a first redundant central node and N first redundant sub-nodes; the first redundant central node is connected to the N first redundant sub-nodes respectively; the first redundant central node is connected to the main node of the main dispatching network, and the setting positions of the N first redundant sub-nodes are respectively the same as the N sub-nodes of the main dispatching network. In this technical solution, the redundant dispatching network is essentially also a telephone dispatching network with a star topology structure, which is equivalent to a complete copy of the main dispatching network. In addition, each main node and sub-node of the main dispatching network are connected to the corresponding nodes of the redundant dispatching network one by one. Once the main node of the main scheduling network fails, the first redundant central node of the redundant scheduling network can replace the main node of the main scheduling network to perform scheduling work on the sub-nodes of the main scheduling network, which will not affect the development of various tasks of the industrial-scale post-processing plant. If a sub-node of the main scheduling network fails, the first redundant sub-node of the redundant scheduling network corresponding to the main scheduling network will communicate with the main node of the main scheduling network through the first redundant central node. The star topology of the redundant scheduling network includes a main node and N sub-nodes connected to the main node; the distance between the sub-node and the main node includes the same or different distances.

[0032] Preferably, Figure 2As shown, the black solid circle is the main node of the main scheduling network; the gray solid circle is the main node of the redundant scheduling network; the white solid circle is the sub-node of the main scheduling network and the sub-node of the redundant scheduling network. The solid line is the connection between the main node and the sub-node in the main scheduling network, and the dotted line is the connection between the main node and the sub-node in the redundant scheduling network. When the main scheduling network is a tree-type topology structure, the redundant scheduling network includes: a second redundant central node and M second redundant sub-nodes; the second redundant central node is connected to the main node of the main scheduling network; at the important nodes of each sub-node in the main scheduling network, a second redundant sub-node directly connected to the second redundant central node is set. The tree-type topology structure is a tree structure. There is a main node of the main scheduling network at the top, and below the main node are multiple child nodes, and below the child nodes are multiple grandchild nodes, and so on, a main scheduling network with a tree structure can be formed. In this technical solution, due to the disadvantage of the main scheduling network with a tree structure, if a problem occurs in a child node, the grandchild nodes below the child node will lose contact with the main node of the main scheduling network, and the grandchild nodes will also lose contact with each other. In order to overcome the above technical problems, a redundant scheduling network can be set up. The redundant scheduling network in this technical solution is to connect the second redundant central node with the main node of the main scheduling network, and then connect the child nodes and grandchild nodes in each main scheduling network to the second redundant central node respectively. That is, the redundant scheduling network formed is a star topology. This structure avoids the loss of connection of the structure below the entire branch when a problem occurs in a branch in the tree structure. Under normal circumstances, the value of the main scheduling network as a tree structure is that the scheduling instructions are transmitted from top to bottom, which allows the branches of the post-processing plant to understand the instructions step by step, and the upper-level nodes decompose the instructions according to the actual situation of the department.

[0033] Preferably, the second redundant sub-node directly connected to the second redundant central node is set at the important node in each sub-node in the main scheduling network, including: setting the second redundant sub-node directly connected to the second redundant central node according to the artificially designated important sub-node, and / or setting the second redundant sub-node directly connected to the second redundant central node at the sub-node with high frequency selected in the next year according to the data of the frequency of telephone use each year. Due to the large site distribution of some industrial-scale post-processing plants, the number of sub-nodes is large. However, in actual working conditions, the dispatching phone will not touch some sub-nodes and sub-nodes at all. Then how to optimize the redundant scheduling network of the main scheduling network is the technical problem to be solved by this technical solution. In this technical solution, the important sub-nodes are artificially selected as the sub-nodes of the redundant scheduling network, so that the above problems can be solved. Alternatively, the number of the second redundant sub-nodes connected to the second redundant central node is changed according to the frequency of use of the sub-nodes of the redundant scheduling network in the previous year.

[0034] Preferably, Figure 3As shown, the black solid circle is the main node of the main scheduling network; the gray solid circle is the main node of the redundant scheduling network; the white solid circle is the sub-node of the main scheduling network and the sub-node of the redundant scheduling network. The solid line is the connection between the main node and the sub-node in the main scheduling network, and the dotted line is the connection between the main node and the sub-node in the redundant scheduling network. When the main scheduling network is a network topology structure, the redundant scheduling network includes: a third redundant central node and K third redundant network nodes; the third redundant central node is connected to the main node of the main scheduling network; J key nodes among the K third redundant network nodes are connected to the third redundant central node, and network connections with the remaining KJ third redundant network nodes are set at the J key nodes. In this technical solution, the network topology structure of the main scheduling network may also fail. For example, a large-scale failure occurs in the network topology, resulting in the inability of some terminals that have not failed to communicate with other sub-nodes. In order to solve the above technical problems, a third redundant central node can be set in the redundant scheduling network, and K third redundant network nodes can be set on important sub-nodes of the main scheduling network, so that even if the failure of the network topology structure causes some important end nodes to lose contact, the third redundant central node of the redundant network node can still reach the important sub-nodes. In this technical solution, the topological structure of the redundant network is essentially a star topological network structure. Of course, each sub-node of the star topological network structure is connected to different important sub-nodes of the main scheduling network, so that other sub-nodes connected to the sub-nodes of the main scheduling network can also communicate with other sub-nodes of the main scheduling network that have not failed.

[0035] Preferably, Figure 4 As shown, the gray solid circle is the main node of the redundant scheduling network; the white solid circle is the sub-node of the main scheduling network and the sub-node of the redundant scheduling network. The solid line is the connection between the sub-nodes in the main scheduling network, and the dotted line is the connection between the main node and the sub-node in the redundant scheduling network. When the main scheduling network is a ring topology structure, the redundant scheduling network includes: a fourth redundant central node and L fourth redundant network nodes; the redundant scheduling network is star-shaped; the fourth redundant central node serves as the center of the star distribution; the L fourth redundant network nodes serve as the edges of the star distribution, and are respectively connected to the fourth redundant central node; the fourth redundant network node is connected one by one with the nodes on the ring of the main scheduling network with a ring topology structure. In this technical solution, if a sub-node of the main scheduling network fails, the entire main scheduling network will fail. If the redundant scheduling network is set as a network with a star topology structure, the above problem can be solved.

[0036] Preferably, when the main scheduling network is a ring topology structure, the redundant scheduling network includes: a fourth redundant central node and L fourth redundant network nodes; the redundant scheduling network is distributed in a star shape; the fourth redundant central node serves as the center of the star distribution; the L fourth redundant network nodes serve as the edges of the star distribution, and are respectively connected to the fourth redundant central node; the fourth redundant network nodes are connected one-to-one with the important nodes on the ring of the main scheduling network with a ring topology structure; the important nodes are determined based on the network failure rate and the importance of the area of ​​the industrial-scale post-processing plant.

[0037] Preferably, Figure 5 As shown, the black solid circle is the main node of the main scheduling network, and the gray solid circle is the main node of the redundant scheduling network; the white solid circle is the sub-node of the main scheduling network and the sub-node of the redundant scheduling network; the black thick line is the bus of the main scheduling network, and the white square line is the bus of the redundant scheduling network. When the main scheduling network is a bus topology structure, the redundant scheduling network includes: a fifth redundant central node, P fifth redundant network nodes and a redundant bus; the fifth redundant central node and the P fifth redundant network nodes are all connected to the redundant bus; the fifth redundant central node is set at the same position as the central node of the main scheduling network, and the P fifth redundant network nodes are respectively set at the important sub-nodes of the main scheduling network. The failure of the bus topology structure is usually that when there is a problem with the bus, the entire main scheduling network will have problems, regardless of whether there are problems with other nodes connected to the bus. The present technical solution sets a redundant bus, and the redundant bus plays a role when the bus of the main scheduling network fails.

[0038] Preferably, Figure 6As shown, the black solid circle is the main node of the main scheduling network, the gray solid circle is the main node of the redundant scheduling network; the black thick line is the bus of the main scheduling network. The black line is the connection between the main node and the sub-node in the main scheduling network and the bus; the dotted line is the connection between the main node and the sub-node of the redundant scheduling network. When the main scheduling network is a combination of a star topology and a bus topology, the redundant scheduling network includes: a star topology redundant scheduling network composed of a sixth redundant central node and q sixth redundant network nodes; the sixth redundant central node is used as the central node of the star topology redundant scheduling network; the q sixth redundant network nodes are respectively connected to the branch nodes of the bus topology structure hanging on the main scheduling network in a one-to-one correspondence. In some factory situations, in order to prevent failures, the main scheduling network can be a combination of a star topology and a bus topology. That is, the backbone network is a bus topology, and then each sub-node hanging on the bus itself can be used as a central node of a star topology, and the central node connects multiple sub-nodes. In this case, if the bus topology fails, that is, the bus fails, the entire main scheduling network fails, and the redundant scheduling network is still needed to play a role. Similarly, the redundant scheduling network in the technical solution is a star topology network. The sixth redundant central node, as a central node, is directly connected to q sixth redundant network nodes, thus directly bypassing the bus of the main scheduling network; and if the bus of the main scheduling network fails, the sixth redundant central node can not only connect to the q sixth redundant network nodes, but also establish connections with other nodes connected to the sixth redundant network node.

[0039] Preferably, Figure 7 As shown, the black solid circle is the main node of the main dispatching network, and the gray solid circle is the main node of the redundant dispatching network; the solid line is the connection between the main node and the sub-node of the main dispatching network; the dotted line is the connection between the main node and the sub-node of the redundant dispatching network. When the main dispatching network is a combination of a star topology and a ring topology, the redundant dispatching network includes: a network topology consisting of a seventh redundant central node and S seventh redundant network nodes; the seventh redundant central node is connected to the central node of the star topology of the main dispatching network; the S seventh redundant network nodes are respectively connected to the sub-nodes in the ring topology of the main dispatching network. In this technical solution, the star topology and the ring topology already have a strong ability to prevent network problems caused by value failures. However, if the redundant dispatching network is added, the reliability of the main dispatching network can be improved, especially for some industrial-scale post-processing plants with extremely high safety. In this technical solution, the redundant dispatching network is a network topology, which can realize the selection of alternative network paths in various fault conditions and achieve a very low failure rate of the dispatching telephone system.

[0040] In summary, the present application includes at least one of the following beneficial technical effects:

[0041] When the main dispatching network fails, the redundant dispatching network that matches the structure of the main dispatching network can be quickly started to achieve normal operation of the industrial-scale post-processing plant.

[0042] The above are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Any feature disclosed in this specification (including the abstract and drawings), unless otherwise stated, can be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.
