As shown in fig. 2 and fig. 3, according to the requirements of the power distribution and utilization communication network and various communication technical characteristics, considering the advantages of various communication technologies to be fully exerted, reducing the application disadvantages of various technologies, and establishing a network structure integrating various technologies with an optical fiber network as a backbone and a wireless technology and carrier communication as an auxiliary in a medium-voltage communication access plane and a low-voltage communication access plane, wherein an OLT represents an optical line terminal; ONU represents an optical network unit; FTU denotes a feeder terminal unit; DTU represents a power distribution terminal unit; TTU denotes a distribution transformer terminal unit.

The communication requirement of the planar power distribution terminal is considered to focus on the reliability requirement, and the power consumption terminal is considered to focus on the communication bandwidth requirement, so that a double-communication channel fusion design is adopted. The specific fusion technology comprises the following steps:
the multi-network cooperation adopts an integration mechanism of internal multiple communication technologies, including 4 modes of EPON and LTE integration, private network multi-band networking, private network multi-band scheduling, wireless private network and wireless public network switching;
(1) EPON and LTE fusion
By adopting an optical carrier wireless RoF technology, an ONU unit of the EPON is used as a TD-LTE base station and a service master station backhaul transmission link unit, a communication technology is integrated in the unit, and an optical carrier is directly utilized to transmit radio frequency signals, so that flexible access of a power distribution and utilization service terminal is realized.
(2) Multi-frequency band networking of private network
A multimode transmission module containing TD-LTE (1.8 GHz frequency band) and LTE230 (230 MHz frequency band) is adopted, multiple communication technologies are integrated in the module, so that micro-grid new energy access service (photovoltaic-charging pile) cross-connection complementary access is realized, and the reliability of the access is improved.
(3) Multi-band scheduling for private networks
A multimode transmission module containing TD-LTE (1.8 GHz frequency band) and LTE230 (230 MHz frequency band) is adopted, multiple communication technologies are integrated in the module, the functions of multi-frequency band and multi-channel transmission and service data stream scheduling are expanded, and the optimal access network of the power distribution terminal is dynamically adjusted according to the occupation condition of the service load bandwidth resources of each network, so that high-bandwidth access is realized.
(4) Wireless private network and wireless public network switching
A multimode transmission module comprising a wireless private network (comprising TD-LTE and LTE 230) and a wireless public network (comprising 4G wireless technology) is adopted, a plurality of communication technologies are integrated in the module, and an optimal access network is automatically switched according to the network communication state at a supporting power service terminal (a concentrator and an intelligent power terminal).
Autonomous self-healing cooperation is achieved by adopting a power distribution terminal relay through base station mode. The function transmission module of the 1.8GHz frequency band TD-LTE extended D2D relay direct base station is adopted, and the distribution terminal can realize normal data transmission by means of the relay terminal by aiming at the distribution network terminal with the coverage area of the distribution terminal which is relatively poor and separated from the core network through the relay direct base station method of the distribution terminal, so that the distribution terminal is separated from a network reconfigurable mechanism under the control of the core network, and autonomous self-healing communication is completed.
The communication engine is configured with a rule base, the communication engine is compared through the rule base, the data is analyzed by matching with a correct protocol object, and the protocol object is stored in the data storage unit. As shown in fig. 6, when the system is started, all the protocols with correct configuration are loaded and stored in a data storage unit in the form of protocol objects, when the system receives equipment data, the corresponding protocol objects are searched in the data storage unit, then the data are analyzed by using the protocol objects, an equipment queue comprises a plurality of equipment types of the internet of things, equipment port numbers and protocol types, and the analyzed data temporarily stores effective data cache areas, and respectively registers data comprising the equipment port numbers, equipment codes, data units, equipment acquisition data and equipment state time.
The protocol object comprises a module protocol and a device protocol, and the uplink data are respectively analyzed according to the corresponding module protocol and the device protocol to obtain the power distribution terminal or the user terminal data.
In this embodiment, splitting the protocol into the module protocol and the device protocol is equivalent to respectively analyzing the uplink data of the power distribution terminal or the user terminal by the corresponding module protocol and the device protocol, and the analysis results are synthesized to obtain the complete data of the power distribution terminal or the user terminal. Whether in a module protocol configuration or a device protocol configuration, the design ideas and the implementation principles are consistent. After the protocol configuration is mainly familiar with the protocol, the fields of each data type are split in an XML node mode according to rules agreed by the system, and the fields supported by the system at present comprise byte types, short integer, long integer, array, fixed-length character strings, unfixed-length character strings, bitwise and equipment packages and the like and can be continuously expanded according to actual requirements. Aiming at the conditions that the data length of some equipment is not fixed or the protocols are special, the system simultaneously reserves a corresponding interface, and a developer realizes the interface to self-define and analyze the data, thereby improving the compatibility and the expandability of the system to various protocols.
When the system receives the equipment data, the corresponding protocol object is searched in the memory, and then the data is analyzed by using the protocol object. The protocol is used as a system plug-in and supports hardware-like 'hot plug': when the system runs, the new protocol is added and modified, and the protocol object is triggered to be generated and updated in the memory.
The protocol standardization configuration unit splits the equipment data into two parts according to the protocol, then carries out data type conversion so as to realize data analysis, and the storage format of the equipment data is set to be BSON/JSON, so that the data of the whole system can be represented by adopting a unified model.
The high concurrency terminal access unit adopts a bidirectional channel to carry out data transmission, and the bidirectional channel registers interesting events. Compared with the existing IO operation, the method has the characteristics of block-oriented, non-blocking and high scalability, has the file access interface of lock and memory mapping files, has high speed, and is suitable for high-concurrency application scenes.
The interesting events comprise a client-side receiving client-side connecting event, a client-side connecting server-side event, a reading event and a writing event. The server and client each maintain an object that manages a Channel, referred to as a Selector, that can detect events on one or more channels (channels). Taking a server as an example, if a Read event is registered on a Selector of the server, at a moment, the client sends some data to the server, the blocking I/O will call the Read () method to Read the data in a blocking manner, and the server of the NIO will add a Read event to the Selector. The processing thread of the server polls the Selector, processes the events if the event of interest arrives when the Selector is accessed, and blocks the processing thread until the event of interest arrives if the event of interest does not arrive.
Considering the connection requirements of a large variety of distribution terminals or user terminals, the system adopts NIO technology to design and realize TCP and UDP communication engines on technical architecture. Meanwhile, multithreading control is added, the thread pool technology is adopted to dynamically allocate and adjust the thread number, the events such as connection, reading and writing are processed asynchronously and efficiently, and the throughput rate and the concurrency number of the system are effectively improved.
As shown in fig. 5, the data analysis unit firstly circularly reads and analyzes the uplink data information of the device through the module protocol, judges whether the length of the next field is enough to be read, analyzes the field data if the length is enough, otherwise records the current step, and then ends the instruction until all the fields are completely read or the data length is insufficient; and then circularly reading and analyzing by the equipment protocol, judging whether the length of the next field is enough, analyzing the field data if the length of the next field is enough, otherwise recording the current step, ending the instruction, and stopping reading until all the fields are completely read or the data length is insufficient.
The distribution terminal and the electricity consumption terminal are configured with a transmission protocol regulated by the equipment management platform to realize the encoding and decoding process of the message, and the equipment management platform is enabled to add a custom rule to realize the service function of message forwarding by setting a rule engine of the distribution terminal or the user terminal equipment, so that the real-time state and the historical data of the distribution terminal or the user terminal equipment are displayed.
The transmission protocol configuration is specifically divided into fields of various data types in an XML node mode according to system convention rules.
It should be emphasized that the examples described herein are illustrative rather than limiting, and therefore the invention includes, but is not limited to, the examples described in the detailed description, as other embodiments derived from the technical solutions of the invention by a person skilled in the art are equally within the scope of the invention.
