In order to further realize communication between devices, communication protocols of different devices need to be coordinated. In practice, the inventor finds that, for different communication protocols, not only the coordination of protocol parameters but also the translation of the communicated data packets are needed, so in this embodiment, for the conversion of the communication protocols, the data of the data packets are represented as the embodied data, which is referred to herein as the content specifically referred to by the data in the data packets, for example, the a device represents an OK signal by the letter "a" when sending the data packets, which is advantageous in that, for different devices, regardless of the logic rules in the data packets, the transcoding of the data packets can be realized by using the embodied data as intermediate data. In this embodiment, it is further required to extract a receiving object of the data packet from the first parameter information as a receiving device, and then obtain the communication protocol configuration information of the receiving device to translate the object data to implement translation and transmission of the data packet.

In one embodiment, when any device sends a data packet to a plurality of devices, communication between the current device and the plurality of devices is established;
when the current equipment sends a data packet through the established communication, sequencing the obtained multiple receiving objects according to a sending sequence, and writing a sequencing result into a communication sequence list;
and reading the communication sequence list in a polling mode, translating the read data packet corresponding to the receiving object, and sending the translated data packet to the read receiving object.
In this embodiment, a many-to-many communication scheme implemented by a communication sequence table is provided, and it should be understood that although the communication sequence table is read in a polling manner in the present application, a receiving object in the communication sequence table may be obtained in a multi-thread reading manner or a manner of directly monitoring the communication sequence table in the prior art; in this way, every time transmission of a packet is performed, translation is less prone to errors, and packet transmission efficiency can be ensured.
In one embodiment, a uniform connection interface is established for different communication modes; the connection interface specifies the input and output interfaces for connection attributes and data.
When the embodiment is implemented, the unified connection interface can specify the input/output port of the connection attribute and the data, and the specification of the connection attribute and the data refers to the unification of the interfaces of different communication modes.

In one embodiment, translating the avatar data into a translation data packet for identification by the receiving apparatus according to the second parameter information comprises:
extracting the corresponding relation between the specific image data and the data in the translation data packet from the second parameter information;
and acquiring a communication protocol logic rule according to the type of the corresponding relation, and translating the image-bearing data into data of a translation data packet according to the communication protocol logic rule and the corresponding relation.
In this embodiment, the inventor finds that if the translation is simply performed through the second parameter information, the translation efficiency is low, so that a communication protocol logic rule is formulated in this embodiment for translating the data packet, where the communication protocol logic rule is obtained based on a type having a correspondence between data and data in the translated data packet, where the type refers to a correspondence between different data types, such as a correspondence between numeric data and text data, and a correspondence between boolean data and text data, and by determining these correspondences and selecting an appropriate communication protocol logic rule, the conversion between different communication protocols can be well adapted, so as to improve the efficiency.
For example, the device communication data "a" represents an OK signal, and the device communication data "1" is considered as an OK signal, and the data translation rule module has a customized rule a: a corresponds to 1, and the customization rule b is: 1 corresponds to a, the communication protocol configuration module configures the received a device data "a" of the device B with the translation rule a, and configures the received B device data "1" of the device a with the translation rule B, so that the A, B device can accurately identify the OK signals of both parties; in this example, it is shown that the data request of the a device can be accurately identified and responded by the B device, and the a device can also accurately identify and receive the response data of the B device, although the A, B devices use different communication methods and communication protocols.
In one embodiment, the communication protocol logic rule is a logic conversion rule between the avatar data and the data in the data packet;

and selecting a corresponding communication protocol logic rule from the categories.
In this embodiment, in order to further improve the translation efficiency, the translation of the packet content is implemented by using the classified communication protocol logic rules, the classification information of the packet content is based on the data classification type of the programming language, for example, for C + +, the data type may be classified into data of boolean type, character type, shaping type, floating point type, double floating point type, and the like, and based on the communication protocol logic rules after the classification, an appropriate communication protocol logic rule may be selected to directly translate the packet, thereby improving the translation efficiency.
For example, obtaining a communication protocol logic rule according to the type of the correspondence, and translating the object data into data of a translation data packet according to the communication protocol logic rule and the correspondence includes:
acquiring trigger bit data from the data packet;
extracting the corresponding relation between the position of the data in the data packet and the trigger position from the communication protocol logic rule, and extracting the data from the data packet according to the corresponding relation;
and when the data packet content is in a digital type, calculating the data packet content through the communication protocol logic rule corresponding to the digital type to generate a translation data packet.
As an example, the communication protocol logic rules mainly include:
1. all characters are input in an English half-corner state;
2. true and false are both valid in the lower case input state, and are only judged in the trigger bit, and meanwhile, the trigger bit is an item that the instruction must have, and the first bit is the trigger bit;

7. if the number of the reference data is not-9999 and the translation instruction is null, directly outputting the data corresponding to the number of the reference data;
8. the reference data number being negative greater than-9999, indicating that the data directly references the inverse digit of the original translation data, e.g. reference number-3, reference the third-to-last digit
9. The method comprises the following steps of using 1^16:1 to indicate that data input into the data with the data being more than or equal to 1 and less than or equal to 16 are translated into 1, and using 17:2 to indicate that the data input into the data with the data being more than or equal to 17 is translated into 2;
10. using False + 4, > =,11111000:3, "+" with the left side being the value of the current input data [ equal to ], the right side being the reference data number that needs to be judged at the same time, the two following "," between is the judgment operator, followed by the value compared with the operator, the operators that can be performed are: ! =, > =, <. The meaning of this translation rule is: when the current reference data input is False and the corresponding reference data number is 4 data > =1111000, the output instruction is 3. The situation that two reference data are judged simultaneously is only supported at present;
11. when the input data and the output command are in a data type, the input data is subjected to the operation result of (input data-standard value) × proportionality coefficient + compensation value) to be the output value.
