Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without any creative effort belong to the protection scope of the present application.
The core of the application is to provide a communication protocol based on the HEX format.
In order that those skilled in the art will better understand the disclosure, the following detailed description will be given with reference to the accompanying drawings.
A communication protocol refers to the rules and conventions that must be followed by two entities to complete a communication or service. Data communication systems in a plurality of different geographical locations interconnected by communication channels and devices must have a common language between them to enable their co-operation for information exchange and resource sharing. What, how and when to communicate must follow certain mutually acceptable rules. This rule is the communication protocol. In computer communication, a communication protocol is used for realizing the standard between a computer and a network connection, and if the network does not have a uniform communication protocol, information transmission between the computers cannot be identified. The communication protocol refers to a communication rule stipulated in advance by the communication parties, and can be simply understood as a common language used for mutual conversation among computers. The two computers must use a communication protocol when communicating. The SCPI protocol is a communication protocol based on ASCII data format, through which instruments can be remotely interacted, such as configuring instrument parameters, obtaining instrument data, etc. All commands in the SCPI exist in the form of ASCII code character strings, after a user sends character strings to an instrument, data returned by the instrument is also the character strings, and then the user needs to analyze the meanings of the returned character strings by himself. The security of the communication content is not high due to the ASCII as a readable character; moreover, the SCPI itself has no check mechanism, and is applied to a bus with unreliable transmission, which may have a risk of frame error. Modbus is a serial communication protocol, needs to operate the slave according to a register address and a coil address, and only supports continuous transmission of continuous addresses, which causes reduction of communication speed if multiple instructions need to be transmitted. Therefore, the present application provides a communication protocol based on the HEX format with high security and high communication efficiency, the communication protocol provided by the present application is implemented based on the RS232/RS422/RS485 serial bus technology, fig. 1 is a schematic flow diagram of the communication protocol based on the HEX format provided by the embodiment of the present application, and the communication protocol is applied to a host, and includes:

HEX is known collectively as Intel HEX and such files are commonly used to transfer programs and data to be stored in ROM or EPROM. A Hex file is an ASCII text file made up of a line of text conforming to the Intel Hex file format. In the Intel HEX file, each row contains one HEX record. These records consist of hexadecimal-coded numbers corresponding to machine language code and/or constant data.
The function codes mentioned in this embodiment refer to different preset data codes corresponding to different instructions, and the corresponding function codes are written into a data protocol framework according to the instruction type corresponding to the data to be sent.

The HEX format has an encryption attribute, effective data can be obtained only by analyzing the data packet according to a set rule by both communication parties, and the identity information of data to be sent in the sent data packet can be discontinuous, namely the data packet contains data information of any address.

and verifying and writing the identity information, the parameter types and the parameters of the data to be sent and the preset frame into a data protocol frame to generate a data packet.
The default frame check mentioned in this embodiment is one of the most commonly used error checking methods in the field of data communication. A frame of data is treated as a long binary number (for example, a piece of 128-byte information is treated as a 1024-bit binary number), then the data is processed by a specified method, a specific number is obtained as a processing result, finally the specific number is attached to an information code as a check code and then transmitted (or stored) together as a frame, the same processing is carried out when receiving (or reading) is carried out, and whether the specific number and the check code obtained by the check processing are the same or not can be found whether an error occurs in the transmission (or storage) process.
The embodiment provides a preferred solution, and the data protocol framework includes: frame header, frame length, frame number, slave equipment address and programmable data stream; wherein, the function code, number, identity information, parameter type and parameter are written into the programmable data stream.
