Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] In the embodiment of the present invention, the entity object is created according to the application data field of the protocol, and the information of each data item in the application data field of the protocol corresponds to each attribute of the entity object; an OPM data table is established and stored, and the OPM The data table describes the corresponding relationship between the information of the data item in the application data domain of the protocol and the attribute mapping of the entity object; when encoding, the received entity object is encoded into a protocol substring accor...

Abstract

The invention discloses an encoding and decoding method and system based on object protocol mapping (OPM). The method comprises the following steps: creating entity objects according to the application data field of a protocol; establishing and storing an OPM data table; during encoding, sequentially encoding the received entity objects into protocol sub-strings according to the attributes of the entity objects, and connecting the protocol sub-strings in series into a protocol string of a protocol data field; during decoding, decoding the protocol string of the received protocol data field into an entity object, reading the OPM data table, acquiring data item information in the application data field of the protocol through attribute reflection of the entity object, and solving the protocol. According to the encoding and decoding method, the protocol is combined with an object-oriented language, so that a program framework is simple, and the code multiplexing rate is high. The method and the system have the advantages of short codes, short development period, high efficiency and high expansibility.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an encoding and decoding method and system based on object protocol mapping. Background technique [0002] In the field of communication technology, various forms of communication protocols are often used as carriers for data communication between various devices with communication functions and computer systems or mobile terminal systems. Since things in the natural language world have various attributes, how to decode and encode user data in the complex application layer is important and difficult for the processing of communication protocols. For example, a simple serial port configuration, described in natural language includes Multiple attributes such as serial port name, baud rate, parity bit, data bit, end bit, etc. [0003] The existing application data information usually carried by a communication protocol is usually in the thousands, and its encoding and decodi...
