Technical Field
[0001] The utility model is applied to the technical field of fiber optic intercom, and particularly relates to an elevator fiber optic IP network intercom conversion device. Background Art
[0002] The existing implementation methods of fiber optic intercom systems are all star structures, which are realized in a point-to-point communication mode. The signals to be transmitted at the elevator end are loaded (or modulated) onto a certain carrier, and then the modulated carrier is transmitted to the fifth-party duty room, and the information is demodulated from the carrier, so as to realize the five-party intercom call required by the elevator. This transmission method is realized by a typical star structure point-to-point transmission method. The disadvantages are that the system structure is relatively single, the data redundancy is serious, the burden on the central manager is heavy, and the security is low. It cannot adapt to large-scale projects with requirements such as multi-duty room linkage or multi-level duty room conversion, such as schools, urban integrations, airports, subway stations, etc.
[0003] The specific disadvantages are as follows:
[0004] I. Single structure: The star structure method has a single dimension. The point-to-point transmission of data circulates between two endpoints A and B, and it cannot meet the data acquisition of the third party C or more parties. The system structure is single;
[0005] II. Heavy burden on the central node: The central node of the star structure needs to handle the communication between all nodes, resulting in an excessive burden on it. This may lead to a decline in system performance, especially in the case of high traffic or high concurrency;
[0006] III. Scattered system distribution and high management cost: In the star structure, after more devices are used, the distribution will be scattered, and it is impossible to achieve highly integrated management and control, resulting in an increase in management costs;
[0007] IV. Low line utilization rate and poor scalability: Each communication line is only used by one central node and one site, resulting in low line utilization rate;
[0008] V. Poor scalability: The scalability of the star structure is also limited because adding new nodes requires direct connection to the central node, which may be physically infeasible or costly.
[0009] Therefore, it is necessary to provide an elevator fiber optic IP network intercom conversion device with a snowflake structure, high scalability, high line utilization rate, high reliability, which can reduce management costs and relieve the burden on the central node. Content of the Utility Model
[0010] The technical problem to be solved by the present utility model is to overcome the deficiencies of the prior art and provide an elevator fiber optic IP network intercom conversion device with a snowflake structure, high expandability, high line utilization rate, high reliability, capable of reducing management costs, and capable of alleviating the burden on the central node.
[0011] The technical solution adopted by the present utility model is as follows: The present utility model includes a general area IP duty room host, a duty room host, a data conversion module, an optical fiber hub, an optical terminal unit, and an elevator intercom. One end of the data conversion module is connected to a plurality of the optical fiber hubs in a parallel connection manner, and the other end of the data conversion module is connected to the duty room host; one end of the optical fiber hub is connected to the optical terminal unit, and the other end can expand the optical fiber hub through parallel connection. The optical terminal unit is connected to the elevator intercom, and the general area IP duty room host communicates with the data conversion module through a local area network.
[0012] From the above, it can be known that the present application has the following effects compared with the prior art:
[0013] I. Adopting a snowflake structure: The snowflake structure is an extension of the star structure. The original dimension tables can be expanded into small fact tables, forming some local "hierarchical" areas, allowing data to communicate with each other and no longer flowing separately between end A and end B;
[0014] II. Alleviating the heavy burden on the central node: The central node of the snowflake structure is no longer the necessary node for all data, but only serves as the last node of the system. The data is released to each sub-dimension for separate processing;
[0015] III. System sub-bureau autonomy, central centralized control, reducing control costs: The snowflake structure divides multiple sub-dimension events, reducing the device stacking due to the increase of events. The central integrates and controls the subset events, and the subset sub-bureaus control, resulting in a reduction in management costs;
[0016] IV. High line utilization rate: The data of each communication line can be controlled by the subset central node or transmitted to the control centers of other subsets or the central center node, resulting in an increase in line utilization rate.
