The system of the embodiment of the present invention is further optimized on the basis of the above system, and provides a specific method for communication between power equipment.

[0089] like Figure 2 As shown, the power equipment communication transmission system 200 based on the power wireless private network includes a communication module 201, a transmission control module 202, a path planning module 203, a communication parameter adjustment module 204, an encryption module 205, a storage module 206, an information acquisition module 207, a detection module 208, a planning module 209 and an execution module 210.

[0090] Optional, such as Figure 2 As shown, the system also includes a communication module.

[0091] The communication module is used to establish a communication connection between the power equipment and the power wireless private network. Based on the requirements of low latency, reliability and security, a wireless communication protocol with modulation and coding technology is adopted to ensure real-time and stable data transmission of the power equipment in different network environments.

[0092] Wherein, the communication module includes:

[0093] Wireless private network access unit, used to connect power equipment to the power wireless private network, dynamically select the best access method according to the network conditions of the power equipment, including LTE, WiFi and 5G wireless communication technologies, and ensure the communication quality under different network conditions;

[0094] A modulation and coding unit, used to dynamically adjust the modulation mode and coding rate of the communication of the power equipment according to the network bandwidth, signal strength and transmission requirements of the power equipment, so as to ensure that efficient and stable data transmission can be maintained when the network environment changes;

[0095] A multi-path transmission unit, for slicing the communication data of the power equipment and transmitting them in parallel through the data transmission path according to the data transmission path determined by the path planning module by using load balancing and link redundancy technology, so as to ensure that when a transmission path fails or is congested, the system can switch to an alternative path to avoid communication interruption or delay;

[0096] The data cache unit is used to cache the communication data temporarily during the transmission process between the power equipment and the power wireless private network, and retransmit the communication data according to the preset retransmission mechanism when a short-term network fluctuation or transmission interruption occurs, thereby ensuring the integrity and continuity of the data, avoiding the load adjustment or fault handling process of the power equipment from being affected by data loss, and enabling the system to have a fault recovery mechanism and diagnosis and repair functions. When the communication link is interrupted or the performance is degraded, the system can quickly diagnose and switch to a backup path to ensure the continuity of data transmission and the normal operation of the equipment, effectively reducing the downtime of the equipment after a fault occurs, and improving the reliability of the system;

[0097] The frequency band selection unit is used to determine the optimal communication frequency band in the available frequency bands based on real-time monitoring and acquisition of signal strength, interference conditions and bandwidth information, so as to ensure the efficiency and stability of the data transmission process.

[0098] The communication module can further enhance the communication stability and anti-interference ability between power equipment and the power wireless private network, especially in complex network environments, to ensure that power equipment can always maintain efficient and real-time communication. Through the modulation and coding unit in the communication module, the system can dynamically adjust the modulation mode and coding rate according to changes in the network environment to adapt to different network conditions. In addition, the multi-path transmission unit uses load balancing and link redundancy technology to quickly switch to the backup path in the event of network failure or congestion to avoid communication interruption.

[0099] Furthermore, determining the optimal communication frequency band based on the acquired signal strength, interference situation and bandwidth information includes: determining a frequency band list, wherein the frequency band list includes multiple frequency bands for communication transmission; obtaining the signal strength, interference level, bandwidth utilization and transmission delay of each of the frequency bands, and deleting the frequency bands with signal strength lower than a preset threshold and / or interference level greater than a preset level to obtain available frequency bands; determining the priority score of each of the available frequency bands according to the signal strength, the interference level, the bandwidth utilization and the transmission delay, and determining the available frequency band corresponding to the highest priority score as the optimal communication frequency band by sorting the priority scores; when the state of the optimal communication frequency band is unstable, updating the optimal communication frequency band by re-determining the priority score, wherein the state of the optimal communication frequency band includes at least one of the signal strength, interference level, bandwidth utilization and transmission delay.

[0100] Specifically, the specific process of the frequency band selection unit selecting the optimal frequency band includes the following four steps:

[0101] 1) First, initialize the frequency band and build the available frequency band list:

[0102] The frequency band selection unit loads all frequency bands supported by the communication transmission system into the frequency band list, including 2.4GHz and 5GHz frequency bands suitable for the power wireless private network, and uses the frequency band list as a candidate set for selection during real-time monitoring.

[0103] 2) Then monitor the frequency band indicators in real time:

[0104] The signal strength and interference of each frequency band are periodically monitored, such as key indicators such as signal-to-noise ratio, number of interference sources, bandwidth utilization, and transmission delay, and the monitoring results are updated in real time. During this process, the frequency band selection unit excludes frequency bands with signal strength lower than the preset threshold or severe interference.

[0105] 3) Then calculate the frequency band priority:

[0106] For available frequency bands, priority scores are calculated based on various indicators. The priority score of each available frequency band is obtained by performing preset operations on signal strength, interference level, bandwidth utilization and transmission delay.

[0107] 4) Dynamic selection of the optimal frequency band:

[0108] The frequency band priority scores are sorted, and the frequency band with the highest score is selected as the current optimal frequency band, which is updated and used as the main channel for data transmission. If the monitored optimal frequency band is unstable, such as reduced signal strength or increased interference, the communication transmission system will recalculate the frequency band priority score and switch to the new optimal frequency band in real time.

[0109] The frequency band selection unit can quickly and accurately select the applicable frequency band in different network environments to ensure the efficiency and reliability of power equipment communication. In addition, the frequency band selection unit can dynamically adjust the frequency band according to the real-time network situation to reduce the impact of signal interference and network congestion on data transmission, thereby improving the reliability and stability of communication. In areas with dense power equipment or when interfered by external wireless signals, the frequency band selection unit can effectively optimize the data transmission path and ensure the efficient operation of the communication transmission system.

[0110] Furthermore, the priority score of each of the available frequency bands is determined based on the signal strength, the interference level, the bandwidth utilization and the transmission delay, including: determining the signal strength score, interference situation score, bandwidth utilization score and transmission delay score respectively based on the signal strength, interference level, bandwidth utilization and transmission delay of the available frequency band and corresponding preset thresholds; for each of the available frequency bands, determining the priority score by taking the weighted sum of the signal strength score, interference situation score, bandwidth utilization score and transmission delay score of the current available frequency band.

[0111] Exemplary methods for determining the priority score include:

[0112] Priority score = ω1*S+ω2*(1-I)+ω3*B-ω4*D

[0113] Among them: S is the signal strength score, I is the interference score, B is the bandwidth utilization score, D is the transmission delay score, w1, w2, w3 and w4 are the weights of the corresponding frequency band indicators respectively.

[0114] The process for determining the signal strength score includes:

[0115] First, determine the range of signal strength in the power wireless private network. For example, divide the signal strength into five intervals: very weak (greater than or equal to 0 and less than 30dBm), weak (greater than or equal to 30 and less than 50dBm), medium (greater than or equal to 50 and less than 70dBm), strong (greater than or equal to 70 and less than 90dBm) and very strong (greater than or equal to 90dBm). Then set the scoring rules, such as setting the corresponding scoring rules by using the segmented scoring method according to the signal strength interval. Different signal strength intervals correspond to different fixed scores: the very weak interval score is 20 points, the weak interval score is 40 points, the medium interval score is 60 points, the strong interval score is 80 points, and the very strong interval score is 100 points. According to the real-time monitored frequency band signal strength value, determine the signal strength interval in which it is located, and then calculate the signal strength score according to the set scoring rule, recorded as S.

[0116] The process for determining the interference score includes:

[0117] First, define the interference level. For example, it can be divided into no interference, slight interference, moderate interference and severe interference. Then set the scoring rules and set the corresponding scores for each interference level. For example, the score for no interference is 100 points, the score for slight interference is 80 points, the score for moderate interference is 60 points, and the score for severe interference is 40 points. Finally, calculate the interference score and determine the interference level based on the real-time monitored frequency band interference. Calculate the interference score according to the set scoring rules and record it as I.

[0118] The process for determining the bandwidth utilization score includes:

[0119] First, determine the bandwidth utilization range from 0% to 100%, and then set the scoring rules. For example, if the score is set by an inverse proportional function, when the bandwidth utilization is 0%, the score is 100 points. As the bandwidth utilization increases, the score gradually decreases, and when the bandwidth utilization is 100%, the score is 0 points. Finally, calculate the bandwidth utilization score. According to the bandwidth utilization value of the frequency band monitored in real time, the bandwidth utilization score is calculated according to the set scoring rules and recorded as B.

[0120] The process for determining the transfer delay score includes:

[0121] First, determine the range of transmission delay, such as dividing the transmission delay into five intervals, namely very low (greater than or equal to 0 and less than 10ms), low (greater than or equal to 10 and less than 50ms), medium (greater than or equal to 50 and less than 100ms), high (greater than or equal to 100ms) and very high (greater than or equal to 200ms or more). Then set the scoring rules, and set the corresponding scoring rules according to the transmission delay interval using the segmented scoring method. Different transmission delay intervals correspond to different fixed scores, with a very low interval score of 100 points, a low interval score of 80 points, a medium interval score of 60 points, a high interval score of 40 points, and a very high interval score of 20 points. Finally, calculate the transmission delay score, and determine the transmission delay interval in which it is located based on the real-time monitored frequency band transmission delay value. Calculate the transmission delay score according to the set scoring rules and record it as D.
