[0090] Determine whether the connection quality index of each terminal device under the intelligent power distribution gateway is lower than the ideal connection threshold. If so, it is determined to be a normally connected terminal device; if not, it is determined to be an abnormally connected terminal device;

[0091] If it is determined to be an abnormally connected terminal device, based on the communication protocol list of the abnormally connected terminal device, each terminal device within the transmission coverage of the communication protocol is determined and recorded as an optional transfer target terminal device;

[0092] Calculate the matching degree of each optional transfer target terminal device, select the optional transfer target terminal device whose matching degree meets the abnormal connection terminal device, and record it as the transfer target terminal device to be selected;

[0093] Based on each candidate transfer target terminal device covered within the transmission range of the communication protocol of the abnormally connected terminal device, an intelligent distribution gateway transfer terminal device management model is established to generate the optimal decision plan for the transfer target terminal device.

[0094] This solution monitors and analyzes the connection quality of heterogeneous terminal devices under the intelligent power distribution gateway in real time, identifies abnormally connected terminal devices, and establishes an intelligent power distribution gateway transfer terminal device management model based on the selected transfer target terminal devices within the communication protocol coverage of the abnormally connected terminal devices, thereby achieving the optimal decision-making plan for the transfer target terminal devices, thereby reducing the network congestion risk of the intelligent power distribution gateway and reducing the performance resource overhead of the terminal devices.

[0095] Reference Figure 2 As shown in the figure, based on the operation data of heterogeneous terminal devices, the connection status of each terminal device is analyzed in real time, and the connection quality indicators of each terminal device are evaluated, including:

[0096] Based on the operation data of heterogeneous terminal devices, pre-process the operation data of each terminal device;

[0097] Extracting the operation characteristics from the operation data of each terminal device to obtain the operation characteristic parameters of the terminal device;

[0098] Based on the operation characteristic parameters of the terminal device, each operation characteristic parameter is assigned the same weight to obtain the operation characteristic weight of the terminal device;

[0099] Calculating a connection quality index of the terminal device according to an operation characteristic parameter of the terminal device and an operation characteristic weight of the terminal device;

[0100] Among them, the calculation expression of the connection quality index of the terminal device is:

[0101]

[0102] Where Q is the connection quality indicator of the terminal device, Wi is the i-th operation feature weight of the terminal device, U i is the i-th operating characteristic parameter of the terminal device.

[0110] The transmission loss formula is:

[0111]

[0112] Where G is the transmission loss rate of the terminal device, φ is the distance attenuation factor, D' is the transmission distance of the terminal device, D is the maximum transmission coverage value of the communication protocol, Y is the transmission loss parameter of the terminal device, log 10 is the logarithmic function with base 10.

[0113] It can be understood that by analyzing the communication protocol list of abnormally connected terminal devices, determining the transmission coverage of each communication protocol, and combining the loss item parameters in the communication request response data, the transmission loss rate of the terminal device is calculated, and the terminal devices that meet the transmission conditions are screened out as optional transfer target terminal devices, which helps to improve connection stability and reduce transmission losses.

[0114] It should be noted that the transmission condition refers to the abnormally connected terminal device as the central position, and considers the transmission loss rate of the optional transfer target terminal device within the coverage of the communication protocol. When the transmission loss rate is sufficient to affect the transfer quality, this part of the terminal devices is filtered out to ensure that the transferred data will not be lost.

[0121] Calculate the matching score of the optional transfer target terminal device through an average weighted algorithm according to the transmission loss rate score of the optional transfer target terminal device, the compatibility score of the optional transfer target terminal device, and the stability score of the optional transfer target terminal device;

[0122] Among them, the average weighted algorithm expression is:

[0123] P=G×W G +H×W H +B×W B

[0124] Where P is the matching score of the optional transfer target terminal device, G is the transmission loss rate score of the optional transfer target terminal device, H is the compatibility score of the optional transfer target terminal device, B is the stability score of the optional transfer target terminal device, and W is the Gis the matching score weight, W H is the compatibility score weight, W B is the stability score weight.

[0125] It should be noted that the transmission loss rate of the optional transfer target terminal device is converted into a percentage format and mapped to the standard scoring rule of the transmission loss rate. For example, if the transmission loss rate is less than or equal to 5%, the score is 10, and if it is between 5% and 10%, the score is 8. The quantitative score is set according to the industry standard or specific requirements, which will not be described in detail here.

[0129] Based on the communication request response data and communication protocol transfer operation data of each candidate transfer target terminal device, the intelligent distribution gateway transfer terminal device management model is substituted, and the candidate transfer target terminal device with the minimum transmission rate and the maximum matching degree is used as the output under the constraint condition to generate the optimal decision plan for the transfer target terminal device;

[0130] Among them, the management model expression of the intelligent power distribution gateway transfer terminal equipment is:
