It should be noted that the terminal is used for meeting different service requirements, that is, communication requirements of devices in the power system, and may be specifically divided into a basic service and an extended service.
In basic service, for example, a distribution automation terminal realizes automatic monitoring and control of the operation of a distribution network, the distribution automation mainly covers distribution network equipment such as a switching station, a ring network unit, a pole switch and the like, and the communication rate is not lower than 2.4 kbps. The electricity consumption information acquisition terminal is used for acquiring, processing and monitoring electricity consumption information of power users in real time, the electricity consumption data acquisition service is not lower than 1.05kbps according to the communication speed of different users, and the transmission speed is not lower than 2.5kbps for load control instructions. The distributed power supply terminal realizes automation of monitoring and controlling operation of the distributed power supply, and the communication speed is required to be not lower than 4 kbps. The accurate load control terminal is a system protection network which takes interruptible loads as specific control objects and is divided into a millisecond-level control system and a second-level and minute-level control system for realizing rapid load control according to different control requirements, wherein the communication speed requires that the millisecond-level control is not lower than 22.4kbps, and the second-level and minute-level control is not lower than 48.1 kbps.
In the extended service, the electric vehicle charging and replacing station terminal generally comprises various centralized charging stations, a charging pile, shore power, a system main station and the like, and mainly realizes connection of a gateway meter and an automatic Transmission Control Unit (TCU) with the power consumption information acquisition system main station and an internet of vehicles platform, wherein the Transmission rate is not lower than 8 kbps. The power transmission and transformation state monitoring terminal is used for monitoring information such as temperature, weather and field environment of power transmission and transformation equipment and lines in real time. According to the relevant power transmission and transformation standards, the transmission rate of a single video access point of the power transmission and transformation state monitoring service is not lower than 2 Mbps. The comprehensive monitoring terminal of the power distribution substation is used for monitoring the state of power distribution equipment/environment and overhauling the state of power distribution, and mainly comprises a station room (a ring main unit, a power distribution room and the like), temperature measurement, live detection and the like, and a small amount of state monitoring of a power distribution line. The transmission rate of the data acquired by the single terminal is more than or equal to 20 kbps; when image service is included, the transmission communication requirement should be greater than or equal to 256 kbps; when video traffic is involved, the transmission communication requirement should be ≧ 2048 kbps. The switching station environment monitoring terminal monitors the working environment of the switching station in real time through the application of a collection and transmission technology, the transmission rate is not lower than 20kbps, the image transmission rate is not lower than 256kbps, and the video transmission rate is not lower than 2 Mbps. The mobile operation service terminal comprises the functions of on-site patrol operation, patrol sign-in, patrol monitoring and the like. The transmission rate requirements are voice traffic 8-64kbps, video traffic 384kbps-2Mbps, data traffic 64kbps-2 Mbps. The warehouse management terminal establishes an intelligent management system covering the whole warehouse through the application of technologies such as a wireless private network, a robot, a wireless radio frequency and the like, and the intelligent management system is based on different service transmission rate ranges: voice service 8-64kbps, video service 384kbps-2Mbps, and data service 64kbps-2 Mbps.
By acquiring the communication demand of the equipment in the power system in the predetermined area, the number and the type of the terminals can be determined according to the communication demand, so as to facilitate the subsequent deployment of the base station.
Optionally, determining a deployment scenario of the base stations in the predetermined area according to the number and the type of the terminals includes: acquiring coverage information of each base station, wherein the coverage information comprises one of the following: the single-station coverage area, the single-station coverage redundancy coefficient, the area regularity coefficient and the self-station deviation coefficient; obtaining a coverage planning result according to the coverage information of each base station; and taking the coverage planning result as a deployment scheme of the base station in the predetermined area.
In the coverage information, the coverage area of a single station is a range that can be covered by each base station, and the coverage areas of the single stations corresponding to different application scenarios are also different. For example, the application scenario may employ 230MHz single station coverage, specifically including 30m hangup, 22.4kbps edge rate. In order to satisfy the service reliability, the redundancy coefficient is covered by a single station so that the number of base stations in a predetermined area conforms to the redundancy coefficient. The single station coverage redundancy coefficient is a parameter of a base station which needs to be added in a preset area for ensuring the reliability of the base station, wherein the higher the level of the preset area is, the corresponding single station coverage redundancy coefficient is. For example, the single-station coverage redundancy coefficient of the central urban area is higher than that of the remote suburban area. The area regularity coefficient is a parameter for adjusting the number of base stations with respect to an actual coverage area of a single station, based on the influence of environmental factors such as terrain and topography on each base station. In general, the predetermined area may relate to a mountain, a water area and the like, the actual area is not regular, the single station coverage area is slightly small to a certain extent, and the adjustment can be performed through an area regularity coefficient. The precondition of the single-station coverage area estimation is based on the uniformly distributed site layout and is a balanced network structure, and the position of a general owned property point hardly meets the requirement of the balanced network structure, so that a self site deviation coefficient needs to be introduced. Namely, the self site deviation coefficient is a parameter for adjusting the uniform distribution of the base stations, and the calculated number of the base stations can be more accurate through the parameter.
Further, a coverage planning result can be obtained according to the coverage information of each base station, and the coverage planning result is used as a deployment scheme of the base stations in the predetermined area. And obtaining the minimum number of base stations meeting the coverage requirement in the predetermined area based on the coverage planning result.
optionally, the coverage planning result includes the number of base stations, and obtaining the coverage planning result according to the coverage information of each base station includes: the number of the base stations is equal to the area of a power supply area/the area covered by a single station x a redundancy coefficient, wherein the redundancy coefficient is equal to the self-station deviation coefficient x the area regularity coefficient x the redundancy coefficient covered by the single station.
In the implementation process, the coverage planning result includes, but is not limited to, the number of base stations, where the number of base stations can be obtained by the following formula: the number of the base stations is equal to the area of a power supply area/the area covered by a single station x a redundancy coefficient, wherein the redundancy coefficient is equal to the self-station deviation coefficient x the area regularity coefficient x the redundancy coefficient covered by the single station. Because the formula relates to the coverage information of each base station, the calculated number of the base stations is more accurate.
It should be noted that, in practical application, each base station has the same performance parameter, and the performance parameter of each base station can be adjusted according to actual requirements to adapt to different application scenarios.
Optionally, the method further comprises: and determining a deployment scheme of a backhaul network according to the deployment scheme of the base station, wherein the backhaul network is used for the base station to carry out data backhaul.
The determining the deployment scheme of the backhaul network according to the deployment scheme of the base station includes: acquiring the position information of each base station, wherein the position information at least comprises a geographical position and a network address; establishing a network return channel according to the position information of each base station; and determining a deployment scheme of the backhaul network according to the network backhaul channel. Furthermore, the service information of the terminal corresponding to the position information of the base station is transmitted through the backhaul network, which not only meets the requirement of information resource transmission, but also realizes data sharing of each base station.
It should be noted that, after determining the deployment scenario of the core network according to the deployment scenario of the base station and the required capacity of the communication network, the method further includes: establishing a data channel between a core network and a background service system; and determining a deployment scheme of the bearer network according to the data channel. The deployment scheme of the bearer network comprises a first router and a second router, wherein the first router is used for bearing production control services, and the second router is used for bearing management information services. By the method, a safe transmission channel can be provided for different service requirements.
an alternative embodiment of the invention is described below.
Fig. 2 is a schematic architecture diagram of a power system communication network deployment according to an alternative embodiment of the present invention, and as shown in fig. 2, the power system communication network deployment may be applied to construct a 230MHz wireless private network, and specific functions of each constituent part are as follows:
Core network equipment: and the system is responsible for terminal authentication and authentication, data encryption, IP address management, mobility management and the like, and is communicated with the service master station through a backbone communication network.

The physical and protocol specifications of the communication module conform to national network protocols, and the communication module can be directly embedded in a corresponding power terminal, so that the implementation complexity is reduced.
In addition, the wireless private network management system is used for configuration management, performance management, fault management, software management and the like of a wireless network; and configures an interface server with an Amplitude Modulation (AM) system.
The method for realizing the deployment processing of the communication network of the power system based on the architecture comprises the following specific steps:
Base station planning
and the base station planning is based on the terminal planning, and the coverage planning and the capacity planning are comprehensively considered so as to finally determine the power wireless private network base station planning scheme. At present, a wireless private network is mainly limited in coverage, the capacity utilization rate is low, and the capacity limitation is not required to be considered temporarily in a planning stage.
1. Coverage planning
Coverage planning is an important method in network planning, and various path loss, link balance and coverage influence factors in the propagation process need to be considered in the coverage planning, so that the maximum possible coverage area of each base station is determined based on the factors, and the minimum number of base stations meeting the coverage requirement in an area is estimated.
In the implementation process, a coverage planning method is adopted to plan a specific power supply area, and the details are as follows:
(1) Single station coverage area
According to the top-level design formulation guide, a specific power supply area is calculated according to the area single-station theoretical coverage area plan under the typical scene of '30 m hang-up, 22.4kbps edge rate', and the reference values are shown in table 1:
TABLE 1
Note that all of the above specific power supply areas employ 230MHz coverage.
(2) Single station coverage redundancy factor
In order to meet the requirement of high service reliability, the number of base stations needs a certain redundancy coefficient according to the technical guide of planning and designing of wireless private network of electric power.
The single station coverage redundancy coefficients of various power supply areas are shown in table 2:
TABLE 2
(3) Coefficient of area regularity
Mountain bodies, water areas and the like can be deducted from the area of the power supply area generally, the actual area is irregular, the scale is smaller due to the fact that single-station area estimation is adopted, the coefficient adjustment is carried out on the coverage radius of various power supply areas according to the actual scene conditions of various cities and the different scenes of different regions of different cities and cities. The area regularity coefficient is shown in table 3:
TABLE 3
(4) coefficient of self station deviation
The precondition of single-station coverage area estimation is based on uniformly distributed station layout and is a balanced network structure, and the position of a general owned property point hardly meets the requirement of the balanced network structure and needs to introduce an owned station deviation coefficient.
in the implementation process, the values of the site deviation coefficients of the specific areas are shown in table 4:
TABLE 4
(5) Coverage planning results
According to the number of base stations, which is the area of the power supply area/the coverage area of a single base station, multiplied by a redundancy coefficient (wherein, the redundancy coefficient is the self-site deviation coefficient multiplied by the area regularity coefficient multiplied by the single-station coverage redundancy coefficient), the number of base stations for planning various power supply areas in a specific area based on coverage planning can be calculated and obtained as shown in table 5.
TABLE 5
2. Base station planning conclusion
The limitation of capacity does not need to be considered at this time, and the coverage planning is the final planning result.

The capacity of the core network is reasonably determined according to the number of base stations planned in the coverage area and service demand prediction.
The key unit of the core gateway needs redundancy configuration, and the area with larger network scale considers local or allopatric disaster recovery.
2. Number of configurations
in this embodiment, the core networks are configured according to a deployment mode of the local cities, and 2 sets of core networks are configured for each local city.
(III) Back haul network planning
1. Network principle
The base station return channel should preferably select the company's own transmission resources, and the channel can be leased when the conditions are not met, and the leased channel should meet the requirements of security, reliability and network management.
The return channel line side adopts an end-to-end 1+1 or 1:1 protection mode, the network where the return channel line side is located needs to provide telecommunication-level service guarantee, and the service end-to-end switching time is less than 50ms under the fault condition.
