As shown in fig. 2, in order to obtain a priority score of an implementation effect of a protocol function in each access protocol, and improve a fitting degree of the priority score and the implementation effect of the protocol function, the inventor proposes that the method for obtaining the priority score includes:

The function implementing step refers to the number of steps of the function instruction to implement the corresponding protocol function.
S202: and scoring the function instructions corresponding to different protocols according to the parameter information and a preset scoring rule, and obtaining the priority score. For example: presetting an identification of a function implementation step as A, wherein the highest score is 10, when the function implementation step of the function instruction is smaller than or equal to 10, A=10-n+1, and when the function implementation step of the function instruction is larger than 10, A=0; the method comprises the steps that a code complexity mark is preset to be B, the highest score is 10, when parameters in a function instruction are complex, B=B-3, when the flow of the function instruction in the function instruction is more, B=B-3, when the parameters to be calculated in the function instruction are more, B=B-4, wherein the judgment of the complexity, the flow and the parameters to be calculated of the parameters in the function instruction can be carried out in a threshold setting mode, if the number of the parameters in the function instruction exceeds a preset parameter threshold, the parameters in the function instruction are complex, and the corresponding score is obtained to be B=B-3; the method comprises the steps that whether an identifier of a standard protocol is C or not is preset, the highest score is 10, C=10 when an access protocol corresponding to a function instruction is the standard protocol, and C=2 when the access protocol corresponding to the function instruction is a non-standard protocol; presetting an identification of a signaling network flow as D, wherein the highest score is 10, when the signaling network flow of the function instruction is smaller than or equal to 512 bytes, D=10, when the signaling network flow of the function instruction is larger than 512 bytes and smaller than or equal to 1024 bytes, D=8, when the signaling network flow of the function instruction is larger than 1024 bytes and smaller than or equal to 2048 bytes, D=1, and when the signaling network flow of the function instruction is in other range, D=1; presetting an identification of a transport layer protocol as E, wherein the highest score is 10, E=5 when the transport layer protocol corresponding to the function instruction is TCP (transmission control protocol ), and E=3 when the transport layer protocol corresponding to the function instruction is UDP (user datagram protocol ); presetting an identifier of a security parameter as F, wherein the highest score is 10, F=10 when the security parameter of the function instruction is a digital certificate, F=5 when the security parameter of the function instruction is private encryption and decryption, and F=0 when the function instruction is a plaintext; the flag of whether the heartbeat connection is preset to be G, the highest score is 5, G=5 when the function instruction is the heartbeat connection, and G=0 when the function instruction is not the heartbeat connection. Further, when the function instruction does not implement the corresponding protocol function, the corresponding priority score is 0, and when the function instruction can implement the corresponding protocol function, the corresponding priority score is a+b+c+d+e+f+g, so as to complete the determination of the priority score. The foregoing is merely an example, and is not intended to limit the parameter information or the scoring rule specifically, and those skilled in the art may configure or adjust the components of the highest score and the parameter information in combination with the service scenario, which is not described herein.

For example: according to the connection function requirements, determining function instructions meeting the connection function requirements, sorting the function instructions meeting the connection function requirements according to priority scores, acquiring a first priority list, acquiring the function instruction with the highest priority score in the first priority list, further acquiring an access program corresponding to the function instruction with the highest priority score, and acquiring the corresponding relation between the equipment to be accessed and the access program according to the number of the equipment to be accessed in the connection function requirements. And further determining a first access mode.
S303: acquiring a second access mode which can meet the corresponding function in the special function requirement and has higher priority score according to the special function requirement and the priority score; and the second access mode uses a private protocol to access the equipment. For example: according to the special function requirements, determining function instructions meeting the special function requirements, sorting the function instructions meeting the special function requirements according to the priority scores, acquiring a second priority list, acquiring the function instruction with the highest priority score in the second priority list, further acquiring an access program corresponding to the function instruction, and acquiring the corresponding relation between the equipment to be accessed and the corresponding access program according to the number of the equipment to be accessed in the special function requirements.
S304: and determining a final access mode of the equipment to be accessed according to the first access mode and/or the second access mode.

if the first access mode can meet the corresponding function in the special function requirement, taking the access program in the first access mode as the access program in the second access mode; because the first access mode uses the standard protocol to access the device, the number of accessible devices of the standard protocol is more, and the CPU and the memory occupy more, so that the first access mode is preferentially used, and the private protocol can be avoided, for example: if the access program in the first access mode can meet the corresponding function in the special function requirement, the priority score corresponding to the access program is properly increased, the access program in the first access mode is used as the access program in the second access mode, multiplexing of the heartbeat link in the first access mode is realized, and new connection establishment is reduced.

s402: and executing a special function request of the equipment by using an access program of a second access mode in the final access mode to finish the function execution, wherein the special function request of the equipment corresponds to the special function requirement of the equipment to be accessed.
In some embodiments, according to the second access manner, the step of executing the device function request includes:

By periodically releasing the connection between the equipment and the access program, the repeated request performance is ensured, and the situation that multiple access modes are always connected on line is avoided.
In some embodiments, when the device connection function request fails to execute, a next function instruction in a first priority list is acquired according to the first priority list, where the first priority list is a priority ordered list of function instructions meeting the device connection function requirement, and the first priority list is ordered from high to low, and device access is performed according to an access procedure corresponding to the next function instruction.
