[0028] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the drawings of the specification. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary persons in the art without creative work should fall within the scope of protection of the present invention.

[0029] Example 1

[0030] Reference Figure 1-Figure 3 , which is the first embodiment of the present invention, and provides a distributed edge computing terminal deployment and configuration method, such as Figure 1 As shown, including:

[0031] S1. Obtain the assembly position of the smart terminal in the substation as a reference point, pre-set the available smart terminals at the reference point, and build a reference point library. The reference point library includes reference points and available smart terminals corresponding to the reference points, including smart terminal models and applicable communication protocols. For example, for reference point A, its available smart terminals include terminal B1, terminal B2...terminal Bn, and these smart terminals may have different communication protocols.

[0032] S2. Compatibility classification is performed on the reference point library corresponding to the adjacent reference points, and the distribution area of ​​the same type of reference points is obtained, and intelligent terminals are deployed at the reference points. The compatibility classification method includes:

[0033] Determine whether the available smart terminals corresponding to two adjacent reference points have a unified or compatible communication protocol. If yes, the two reference points are classified into the same category. In this case, the available smart terminals of the two reference points in the same category may only include terminal B1, terminal B2 and terminal B3. Otherwise, the two reference points do not belong to the same category.

[0034] Check whether the available smart terminals corresponding to two reference points of the same category have a unified or compatible communication protocol with the available smart terminals corresponding to another adjacent reference point. If so, the reference points are classified into the same category. At this time, the available smart terminals of the three reference points of the same category may only include terminal B1 and terminal B2. Otherwise, the reference points do not belong to the same category. Repeat the screening in sequence to screen out smart terminals corresponding to several reference points of the same category with the same compatibility.

[0035] The compatibility judgment logic of the compatibility classification is: for any two adjacent reference points, if there is at least one pair of compatible smart terminals, the two reference points are considered to be compatible.

[0036] The process of compatibility classification is as follows:

[0037] Initialize an empty collection to store the classified reference points.

[0038] For each reference point A, check whether it has been classified into a category in the empty set.

[0039] If not, create a new category C1 and add reference point A to it.

[0040] Then, for each adjacent reference point AN of reference point A, repeat the above compatibility determination process;

[0041] If reference point A is compatible with reference point AN, then reference point AN is added to C1.

[0042] This process is repeated until all adjacent reference points have been checked.

[0043] Finally, add C1 to the empty set to complete the classification.

[0044] S3. According to the spatial distribution of all reference points and the volume of the effective communication area, when several effective communication areas can be included in all the reference points of the spatial distribution, the full coverage of the effective communication area is completed, and several effective communication areas are used as effective node areas. In this process, it is easy for the effective node areas to partially overlap. In order to avoid signal interference, frequency planning is performed for the wireless communication devices in the effective node areas with overlapping parts, that is, by reasonably allocating spectrum resources, it is ensured that the signals between the wireless communication devices in different effective node areas do not interfere with each other.

[0045] As a detailed description, frequency planning methods include:

[0046] After screening out the valid node areas with overlapping parts, first set the frequency in a valid node area as reference frequency one, and set the reference frequency two that does not interfere with reference frequency one for the valid node areas with overlapping parts. Repeat the operation and set the reference frequency three that does not interfere with reference frequency one and reference frequency two for the subsequent valid node areas with the same overlapping parts. And so on, the reference frequency N can be set.

[0047] S4. Select a wireless communication device that can communicate with the largest number of smart terminals corresponding to the same type of reference points in the effective node area, establish a wireless communication device at the center of the effective node area, establish communication between the wireless communication device and the smart terminals corresponding to the reference points in the effective communication area, and establish an edge processing terminal next to the wireless communication device as a distributed node.

[0048] In order to ensure effective communication between the edge processing terminal and all smart terminals in the effective node area, the smart terminal that directly communicates with the above wireless communication device is recorded as the direct connection end, and the smart terminal corresponding to the indirect connection end in the effective node area is selected as the indirect connection end, and the wireless communication system of the indirect connection end is established. The establishment method includes:

[0049] A. Count the number of indirect connection terminals in the same valid node area and determine whether their protocol communications are unified or compatible. If yes, go to B; if no, go to C.

[0050] B. Calculate the cost of setting up a communication converter at the non-direct connection end to obtain the conversion cost, calculate the cost of setting up another wireless communication system in the effective node area to obtain the total cost, and when the conversion cost is higher than or equal to the total cost, go to D; when the conversion cost is lower than the total cost, go to C;

[0051] C. Set up a communication converter at the non-direct connection end, and establish protocol communication between the communication converter and the wireless communication device to complete the communication in the effective node area;

[0052] D. Set up another wireless communication device next to the wireless communication device, establish protocol communication between the other wireless communication device and the non-directly connected terminal, and complete the communication in the effective node area.

[0053] S5. Deploy several distributed nodes and communication channels with the background to complete the distributed deployment of the edge terminals in the substation area.

[0054] As an expanded explanation, when there is partial overlap of the valid node area and there is a reference point in the overlapping part, the smart terminal corresponding to the reference point is marked as a repetitive terminal. When a distributed node receives information from a repetitive terminal, the information is marked as repetitive, and it is verified whether the adjacent distributed nodes receive the same repetitive terminal information. If so, it means that the two distributed nodes are in normal working condition. If not, the two distributed nodes are marked as abnormal and an alarm is issued.

[0055] As an optional embodiment, reference point A, reference point B and reference point C are adjacent reference points, the available smart terminals at reference point A include terminal B1, terminal B2 and terminal B3, the available smart terminals at reference point B include terminal A1, terminal B2 and terminal B3, and the available smart terminals at reference point C include terminal B1, terminal B2 and terminal A3;

[0056] When the communication protocols of terminal AN and terminal BN are incompatible, it can be seen that when deploying terminals at reference points A, B and C, only terminal B2 meets the requirements, and the three terminals B2 are deployed at reference points A, B and C respectively.

[0057] As an optional embodiment, according to the spatial distribution of all reference points and the volume of the effective communication area, when several effective communication areas can be included in all reference points of the spatial distribution, the full coverage of the effective communication area is completed, and several effective communication areas are used as effective node areas. In this process, it is easy for the effective node areas to partially overlap, such as the effective node area 1, the effective node area 2 and the effective node area 3 partially overlap, such as Figure 3 shown.

[0058] The shaded part is the overlapping part of the effective node area one, the effective node area two and the effective node area three. At this time, the frequency is first set in the effective node area one as the reference frequency one, and then the reference frequency two is set for the effective node area two, on the premise that the reference frequency two will not interfere with the reference frequency one, and then the reference frequency three is set for the effective node area three, on the premise that the reference frequency three will not interfere with the reference frequency one and the reference frequency two.
