The invention aims to provide an information transmission method and an information transmission system for a 5G power distribution network, which can reduce transmission delay and improve monitoring timeliness.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Fig. 1 is a schematic flow chart of an information transmission method for a 5G power distribution network provided by the present invention, and as shown in fig. 1, the information transmission method for the 5G power distribution network provided by the present invention includes:
s101, acquiring a first transmission link from a switch SW of data to be transmitted in a power grid to a base station; acquiring a second transmission link from the switch SW of the data to be transmitted to any switch SW in the power grid and from the corresponding switch SW to the base station;
s102, if the shortest transmission link is the first transmission link, directly transmitting the state data of the switch SW of the data to be transmitted by using the first transmission link; the shortest transmission link is a transmission link with short time delay;
as another specific embodiment, the shortest transmission link is the transmission link with the shortest transmission distance.
And S103, if the shortest transmission link is the second transmission link, transmitting the state data of the switch SW of the data to be transmitted to the switch SW in the second transmission link, and transmitting by using the second transmission link to realize D2D communication of the switch SW.
As a specific example, S103 specifically includes:
when the switch SW of the data to be transmitted and the switch SW in the second transmission link are the same base station, the base station configures the spectrum resources of the switch SW of the data to be transmitted and the switch SW in the second transmission link and sends a signal to the switch SW of the data to be transmitted and the switch SW in the second transmission link;
after the configuration is completed, the state data of the switch SW of the data to be transmitted is transmitted to the switch SW in the second transmission link.
As another specific example, S103 specifically includes:
when the switch SW of the data to be transmitted and the switch SW of the second transmission link are the same base station, before installation, the same preset spectrum resources are configured in the switch SW of the data to be transmitted and the switch SW of the second transmission link, and the state data of the switch SW of the data to be transmitted is directly transmitted to the switch SW of the second transmission link.
Through the two embodiments, D2D communication of different switches SW under the same base station is realized.
As another specific example, S103 specifically includes:
when the switch SW of the data to be transmitted and the switch SW in the second transmission link are different base stations, signaling is sent between the different base stations, and the configured spectrum resource is sent to the switch SW of the data to be transmitted and the switch SW in the second transmission link;
after the configuration is completed, the state data of the switch SW of the data to be transmitted is transmitted to the switch SW in the second transmission link.
As another specific example, S103 specifically includes:
when the switch SW of the data to be transmitted and the switch SW of the second transmission link are different base stations, before installation, the same preset spectrum resources are configured for the switch SW of the data to be transmitted and the switch SW of the second transmission link, and the state data of the switch SW of the data to be transmitted is directly transmitted to the switch SW of the second transmission link.
Through the two embodiments, D2D communication of different switches SW under different base stations is realized.
Signaling interaction is needed among the base stations, and the time needed for information interaction among the base stations is long; moreover, the spectrum resources configured for each base station are different, and the situation that the allocated spectrum resources are not matched occurs to a great extent, as shown in fig. 4, for example, the resources allocated to SW2 by the base station 1 are between frequency points f1 to f2, and the resources allocated to SW6 by the base station 2 are f3 to f2. When D2D communication is performed between SW2 and SW6, the pre-allocated resources are different, and SW2 and SW6 cannot communicate with each other, or if communication is established, SW2 is used as a transmitter, SW2 firstly informs SW6 of the resources performing D2D communication with SW6, and then data transmission is performed, so that time delay is increased.
Therefore, a resource pre-configuration method is proposed, which is applied to a scenario (SW 2 and SW 6) of cross-base-station D2D communication, taking base station 1 as an example, base station 1 allocates two resources to SW2, the first resource is used for D2D communication between different SWs under the same base station and communication between SW2 and base station 1, and the second resource is used for a D2D communication mode of SW2 and SW6 cross-base station.
The first parameter is used to indicate the type or mode of communication, and occupies 1 bit. When configured as "0", it means that the first resource is used for D2D communication, and when configured as "1", it means that the second resource is used for communication.
When SW2, as a transmitter, transmits information to SW6 in a D2D manner, the first parameter is configured to be "1" and added to the header of the information to be transmitted.
And the SW6 is used as a receiver to monitor the first resource and the second resource simultaneously or successively, and receives the information on the second resource after the first parameter is demodulated to be 1.
For "simultaneous or sequential monitoring", specifically:
and simultaneously monitoring: if the SW6 capability is strong, as shown in fig. 4, the SW6 may set the radio frequency channel (or listening range) between f1 and f3, and at this time, the SW6 may listen to green and orange resources at the same time;
monitoring in sequence: if the capability of the SW6 is very weak, as shown in fig. 4, the SW6 can only set the radio frequency channel (or the monitoring range) to be between f1 and f2 to monitor the corresponding resource, and after the SW6 finishes monitoring the corresponding resource, adjust the monitoring range to be between f2 and f3 to monitor the corresponding resource.
A power distribution switch monitoring terminal FTU is arranged in the switch SW;
the distribution switch monitoring terminal FTU has the functions of remote control, remote signaling and fault detection, is communicated with a distribution automation master station, provides the running condition of a distribution system and various parameters, namely information required by monitoring and controlling, including on-off state, electric energy parameters, interphase faults, grounding faults and parameters in fault, executes commands issued by the distribution master station, adjusts and controls distribution equipment, and realizes the functions of fault positioning, fault isolation, quick recovery of power supply in a non-fault area and the like; and the FTU is an intelligent terminal device installed on a distribution room or a feeder. The system can communicate with a remote power distribution substation, sends the operation data of the power distribution equipment to the power distribution substation, and can also receive the control command of the power distribution substation to control and adjust the power distribution equipment.
The FTU has the characteristics of small volume, large quantity, capability of being arranged on an outdoor feeder line, transmitter arrangement, direct alternating current sampling, high temperature resistance, cold resistance, adaptability to outdoor severe environment, small acquired data volume, low requirement on communication speed and high requirement on reliability.
As shown in fig. 2 and 3, the D2D communication between the switches SW of the present invention reduces the transmission delay of the transmission link, thereby improving the timeliness of monitoring.
Corresponding to the method, the invention provides an information transmission system of a 5G power distribution network, which comprises the following steps:
the transmission link determining module is used for acquiring a first transmission link from a switch SW of data to be transmitted in the power grid to the base station; acquiring a second transmission link from the switch SW of the to-be-transmitted data to any switch SW in the power grid and from the corresponding switch SW to the base station;
the first transmission module is used for directly transmitting the state data of the switch SW of the data to be transmitted by using the first transmission link if the shortest transmission link is the first transmission link; the shortest transmission link is a transmission link with short time delay;
and the second transmission module is used for transmitting the state data of the switch SW of the data to be transmitted to the switch SW in the second transmission link if the shortest transmission link is the second transmission link, and transmitting the state data by using the second transmission link to realize the D2D communication of the switch SW.
