4) data of stipulations one are converted into the data of stipulations two in data processing module one, enter the handling process of stipulations two data, enter the data processing module two of stipulations two, proceed stipulations conversion or transmission, perhaps do other processing.The data of stipulations one are resolved out at data processing module one, do corresponding processing according to the result, such as: transmit leg is carried out corresponding etc., then convert the data format that stipulations two and stipulations one processing module all are familiar with to, enter the data processing module of stipulations two, carry out the stipulations conversion, or do other processing.
The aforesaid a kind of intelligent protocol expanded conversion method based on embedded platform, it is characterized in that: described data transmit-receive module comprises data buffer zone one, is used for holding the data processing module of other stipulations or the data that will send that data transmit-receive module sends over.The data buffering of data transmit-receive module holds all data that need to send by this data transmit-receive module, and data may be from any data processing module, also may be from other data transmit-receive modules.
The aforesaid a kind of intelligent protocol expanded conversion method based on embedded platform, it is characterized in that: described data processing module is included as data buffer zone two, is used for holding data transmit-receive module and divides the data that send.
The beneficial effect that the present invention reaches:
The intelligent protocol expanded conversion method based on embedded platform of the present invention by every kind of stipulations being set up a data transceiver module and data processing module, is carried out the conversion of stipulations, can realize the data transaction of different protocol types.
Description of drawings
Fig. 1 is data flow figure in the stipulations transfer process of the present invention.
Embodiment
Fig. 1 is data flow figure in the stipulations transfer process of the present invention.Suppose, there are stipulations one and 2 two kinds of data of stipulations to carry out the stipulations conversion, the data flow of this stipulations conversion method as shown in Figure 1, the data of stipulations one type at first access by the communication interface of embedded platform, does data according to concrete protocol type distribution after data are received and process, according to the result that data are processed, data or be converted into the type of data format that data processing module one and data processing module two can both be identified, enter the handling process of stipulations two data, perhaps do other processing.The data of stipulations two types are also processed such as the processing procedure of stipulations one.
The realization of this method cooperatively interacts by data transmit-receive module and data processing module.
Data transmit-receive module: data transmit-receive module is the implementation method towards communication protocol, for each communication protocol that need to use, for example TCP, UDP, RS485, Webservice etc. will set up a realization, the distribution of the reception of responsible data/transmission and data.Like this, no matter transfer of data adopts any communication protocol, all only needs to increase the data transmit-receive module of response, and when communication protocol did not increase, the implementation method that newly-increased data only need be called the specific data transceiver module got final product.
Data transmit-receive module also needs to be responsible for the distribution of data, with the data of receiving, simply resolves, and makes a thorough investigation of the result who resolves, and send corresponding data processing module with data.
Data processing module: data processing module is the implementation method towards stipulations, the specific data processing module of the foundation that the stipulations of each type are required to be.The major function of data processing module comprises that data are processed and data transaction, and data processing function comprises judging whether data are legal, resolution data, response data, translation data and be sent to data transmit-receive module.The processing of newly-increased protocol type data only needs to increase corresponding data processing module.
Functional module multiplexing: data transmit-receive functional module and data processing function module all are reusable, and the quantity that increases deal with data is multiplexing existing functional module then.Adopting different communication protocol to access in the situation of data of multiple protocol type, functional module multiplexing so that the realization of system is simple.Data for new access dispose corresponding data transmit-receive module and data processing module for it, can realize the stipulations conversion to data.The multiplexing functional module that refers to when setting up new data transaction flow process, only need be called corresponding data transmit-receive module and data processing module once setting up arbitrarily matched combined use.
The realization of stipulations conversion method of the present invention relies on the hardware resource of embedded platform and the functional module that software approach is set up.Set up the master control framing program for whole stipulations conversion, be responsible for entering, withdrawing from of program, the loading of functional module, and other are such as functions such as house dogs.
For concrete communication protocol is set up independently data transmit-receive module, this data transmit-receive module comprises a data buffering area and holds the data that will send that other functional modules send over.
For concrete stipulations are set up independently data processing module, this data processing module also comprises a data buffering area and holds data transmit-receive module and divide the data that send.
Set up configuration file, be all data configuration data transmit-receive module and data processing modules.
The present invention is illustrated according to the preferred embodiment, should be appreciated that but above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the form of equivalent transformation obtains, all drops within protection scope of the present invention.
