In order to solve the above problems, the currently adopted solutions are mainly divided into two types, one is to dock only one type or one type of device during platform construction, and the code structure needs to be continuously adjusted for the docking of multiple types of devices. Secondly, a description Protocol similar to a Google Protocol buffer is adopted, and Protocol Buffers are a light and efficient structured data storage format, can be used for structured data serialization or serialization, are suitable for data storage or RPC data exchange format, and can be used for language-independent, platform-independent and extensible serialized structured data formats in the fields of communication protocols, data storage and the like. However, there are still many problems in google proto Buffer when it is applied in the field of internet of things. Firstly, Google Proto Buffer is a custom protocol, which cannot effectively describe the well-defined protocol format, and secondly, Google Proto Buffer does not support bit operation and conditional operation, nor does it support standardized functions.
Specifically, when the internet of things field equipment is used for communication, a bit-defining mode is adopted to transmit data in many times in order to reduce bandwidth requirements, a bit-defining mode is also adopted to define conditions sometimes, if yes, the following data is read, otherwise, the data does not exist, and the Google Proto Buffer is mainly designed for inter-platform communication, does not operate on bits, and does not provide such conditional operation. Moreover, the Google Proto Buffer is only a protocol definition and analysis tool, and does not support the protocol standardization function.
For accessing binary equipment (equipment using binary communication) with inconsistent data types and inconsistent data formats to the same platform, the existing access methods have certain limitations, cannot support the access of any binary equipment, cannot standardize the accessed equipment, and are convenient for platform reading.

In one embodiment of the invention, the message segmentation rule comprises three parts of binary basic information, a message segmentation method and a transfer processing method. Specifically, binary basic information: the endian processing mode of the binary stream is indicated. The message segmentation method comprises the following steps: the general internet of things message can be divided into two major types of messages of fixed length type and variable length type, the fixed length type message generally starts with a message start mark (special character or character string), the definition of protocol length is followed, and the message division is completed by the byte number of the message start mark plus the protocol length; the variable length class means that the message has no fixed length, and the division of the message is realized by the length marked by the start mark and the end mark or the length field. The escape processing method comprises the following steps: because the data with the same value as the start mark or the end mark in the message body needs to be transmitted by using an escape mode, the data access module needs to complete the processing of escape data according to a predefined escape rule, thereby forming independent protocol message data.

In this embodiment, the standard attribute set definition is provided by a third-party internet of things application platform. Based on the method, after the internet of things device protocol data is processed by the random binary device access analysis and standardization system, a standard attribute set which can be used by a third-party internet of things application platform is formed, so that the application platform and the internet of things device are completely decoupled.

s1, predefining rules of any binary equipment access analysis system; wherein the predefining comprises defining a message segmentation rule, defining an original attribute set and defining a standard attribute set; the definition of the message segmentation rule comprises byte order rule definition, message segmentation method definition and escape rule definition; the definition of the original attribute set comprises attribute analysis definition, attribute analysis sequence and reading condition definition; the standard attribute set definition comprises attribute mapping rule definition and attribute set completion condition definition;
s2, receiving the binary data stream sent by the accessed binary equipment, and segmenting and escaping the received binary data stream to obtain the original message data;
s3, analyzing the original message data, filling corresponding attribute values in predefined original attributes to obtain an original attribute set;
and S4, filling the attribute values mapped by the original attribute set into the predefined standard attribute set to form a standard attribute set.
6. The method for arbitrary binary device access parsing and standardization according to claim 5, wherein the step S1 includes the following steps:
s11, storing the predefined message segmentation rule in the message segmentation rule definition module;
s12, storing the predefined original attribute set in the original attribute definition module;
s13, storing the predefined standard attribute set in the standard attribute set definition module.
7. The method for any binary device access parsing and standardizing as claimed in claim 6, wherein the step S2 comprises the steps of:
s21, reading protocol data;
s22, judging whether the protocol message starts or ends, discarding the current byte if the protocol message does not start, returning to S21, if the protocol message ends, entering S23;
s23, segmenting the protocol data by using the message segmentation rule stored in the message segmentation rule definition module, entering the step S24 if the protocol data can be segmented, and returning to the step S21 if the protocol data cannot be segmented;
and S24, performing escaping on the data message forwarded by the data segmentation module through the escaping processing module to obtain the original message data.
8. The method for any binary device access parsing and standardizing as claimed in claim 6, wherein the step S3 comprises the steps of:
s31, according to the message ID of the original message data, obtaining the corresponding original attribute set definition through the original attribute definition module;
s32, traversing the attribute analysis definition in the original attribute set definition in sequence, creating an attribute reader according to the attribute analysis definition, and determining the reading length;
s33, judging whether the attribute analysis condition is satisfied, if so, reading the attribute value of the attribute, if not, returning to the step S32;
s34, judging whether the attribute value of the attribute needs to be converted, if so, converting the attribute value and then putting the converted attribute value into an original attribute set, and if not, directly putting the converted attribute value into the original attribute set;
s35, judging whether all the attributes in the original attribute set traverse, if yes, going to step S4, if not, returning to step S32.
9. The method for arbitrary binary device access parsing and standardizing as claimed in any one of claims 5-8, wherein said step S4 includes the steps of:
s41, traversing all attributes in the original attribute set;
s42, traversing all the defined standard attribute sets;
s43, assigning values to the attributes in the standard attribute set;
and S44, detecting whether the attribute of the standard attribute set is completely assigned, if so, ending the step, otherwise, returning to the step S2.
