All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
The invention is further described with reference to the following drawings and specific examples, which are not intended to be limiting.
A communication unit in a twice-fused solid insulating ring net cage, as shown in figure 1, comprises,
a communication backplane 1, the communication backplane 1 comprising,
the RS485 serial ports 4 are respectively connected with the external interval unit and the power supply control unit, specifically, the communication unit and the interval unit adopt high-speed serial ports RS485 for communication, the communication unit, the interval unit and the power supply control unit are abandoned to be in multi-connection communication interaction with Ethernet, an optical cable terminal box, an ONU data box and other equipment are omitted, the functions of data acquisition, remote control, fault on-site action, communication and the like of the interval control unit and the power supply control unit are completed, the size is small, the installation is easy, the disassembly and the maintenance are convenient, the installation and the debugging of a field device are facilitated, and the cost is saved;

It should be noted that, in this embodiment, the RS485 serial port 4 is selected for use as the master serial port, and 6 spacing units are provided in this embodiment, because the RS485 serial port 4 communication is more rigorous to the structure requirement of 1 master and multiple slaves, the specific matching resistor needs to be obtained from the design test. At present, a star connection mode is adopted in a main path of a communication unit, and multiple attempts find that a very critical step is to realize a 1 main 6 slave mode: the master and slave matching resistances must be both 120 ohm resistances. Otherwise, data receiving and sending are abnormal, so that a basic link channel cannot be realized, and normal communication cannot be realized between equipment and intervals of the whole communication unit.
In a preferred embodiment, the communication backplane 1 is provided with:
the power interface 7 is arranged at the upper left part of the communication bottom plate 1 and is connected with a direct-current power supply;
and the time-second pulse interface 8 is used for synchronizing the time-second pulse signals to each interval unit.

and the Bluetooth interface 12 is connected with the second communication module 3.
Specifically, the communication backplane 1 is further provided with an indicator light group 13 disposed at the bottom of the communication backplane 1.

The communication unit presets the time interval of collection, and the first communication module 2 collects all interval unit data through traversal of the main serial port according to the time interval.
Specifically, the first protocol encapsulation unit 21 is connected to the 4G interface 14 and/or the ethernet interface 6 and/or the fiber interface 5, and encapsulates the data in the storage unit into a specification suitable for the primary station to receive.
In a preferred embodiment, the second communication module 3 comprises:
the second micro-processing controller 22 is connected with the Ethernet interface 6 and the maintenance module;
a second protocol encapsulation unit 23 connected to the second microprocessor controller 22 and the first protocol encapsulation unit 21;
a second flash memory unit 24 connected to the second microprocessor controller 22;
a light emitting unit 25 connected to the second microprocessor controller 22;
a positioning unit 26 connected to the second microprocessor controller 22;
and a second watchdog 27 connected to the second microprocessor controller 22.
In a preferred embodiment, the first communication module 2 needs to receive a data transmission request from the master station before sending data to the master station, but when the first communication module 2 collects the alarm data, it does not need to receive the data transmission request from the master station, and directly sends the alarm data to the master station. The IEC101/104 protocol has two transmission modes: balanced and unbalanced transport. The balanced transmission mode is adopted in the full-duplex channel structure of point-to-point and a plurality of point-to-point, and only the unbalanced transmission mode is adopted in other channel structures. The IEC101 protocol in the balanced transmission mode is a question-answer + cycle type protocol, namely, a main station end and a substation end can be used as starting stations; and when the method is used for an unbalanced transmission mode, the IEC101 protocol is a question-answering protocol, and only the master station end can be used as a starting station.
In a preferred embodiment, when the interval unit fails, the interval unit directly transmits the recording data of the node at the time when the failure occurs to the second communication module 3, and the second communication module 3 directly performs data encapsulation on the recording and broadcasting data and transmits the data to the master station.
Further, when the interval unit fails, because the occurrence of the fault is very fast, when the master station needs to know the voltage information before, during and after the fault of the time node where the fault occurs, it takes much time to acquire data through the first communication module 2 and store the data in the flash memory chip, and the data cannot be sent to the master station quickly, so that the second communication module 3 needs to bypass the flash memory chip to directly package and send the data, and the time difference of data transmission between the master station and the interval unit is shortened.
In conclusion, the communication unit in the embodiment is small in size, easy to install, disassemble and maintain, convenient for field device installation and debugging, and cost-saving, and because the reserved space of the ring main unit is reduced, the requirements of installation, construction and operation and maintenance are met, and the defects that a large-capacity optical fiber wiring unit and an industrial Ethernet switch cannot be installed due to unreasonable design of the reserved space of most ring main units, and a floor type optical fiber communication equipment box needs to be additionally arranged outside the ring main unit are overcome.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention.
