Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified as follows:
A kind of communication sharing data area design management method that is applied to the various communication interfaces gateway comprises step: in driving service layer, in memory headroom, open up earlier the communication sharing data area of a zone as various communication interfaces and agreement; Set up a communication sharing data area access interface again;
Said communication sharing data area comprises: communication interface data field, communications protocol configuring area, Debugging message output area and running state information district; Said communication interface data field has a plurality of, and each communication interface data separation is agreement IO data field and communication packet data field; The IO point data that agreement IO data area stores is corresponding with communications protocol, the input and output message of communication packet data area stores communication interface gives over to the protocol-driven debugging and uses;
For the advanced row communication protocol analysis of all communication interfaces of user application layer, again through the communication interface data field in the said communication sharing data area access interface visit communication sharing data area; In the time of visit, according to the corresponding relation between the corresponding communications protocol in communication interface data field, distinguish different data access authorities with client layer, communications protocol can only be visited corresponding communication interface data field under its normal authority;
For the zones of different in the communication sharing data area different operation interface and operating right are arranged:
1) agreement IO data field is operated before, need open agreement IO data field; The communications protocol corresponding with the data field has the authority to the read-write of agreement IO data field, writes only to limit to the input data to carry out, and other operations only possess read right;
2) the communication packet data field is the renewal of being accomplished the communication sharing data area by the backstage service function that provides of management system of communication sharing data area when the transmitting-receiving of letter literary composition automatically, is used for debugging or keeping watch on to communications protocol;
3) the communication protocol configuring area is that the backstage service function that the management system by the communication sharing data area provides is resolved the configuration data that configuration file obtains;
4) state in communications protocol changes, or to the communication sharing data area when operating, the management system of communication sharing data area can be deposited corresponding information in the said running state information district;
5) Debugging message output area storage: when the user debugs, can from other districts, read information and come, deliver to host computer and show.
Required service function and the operation-interface of operation communication sharing data area comprises: consultative management function, agreement IO data field read and system's backstage service function;
The consultative management function comprises: the Register Cancel of agreement, the configuration operation of agreement stop, to inspection and the prompting of communications protocol to the boundary limitation of the authority of different communication interface data district visit and data;
Agreement IO data field read: opening, closing and read-write interface to the communications protocol data field; Wherein to carry out the inspection of operating right; Communications protocol can only be read and write own corresponding protocols IO data field; To the read right that has only of its agreement IO data field, when carrying out read-write operation, also to check simultaneously read/write address whether correctly, whether the situation of the visit of crossing the border arranged;
System's backstage service function, comprise user's Debugging message write and the writing of management, protocol running state information, configuration file is resolved and the communications protocol debugging.
The step of said communication sharing data area operation:
At first, when starting, accomplish the parsing of system protocol configuration and writing of communications protocol configuring area;
Then, communications protocol is registered startup one by one, and opens required communication interface data field,
Next, operation is upgraded in the preservation of carrying out communication, IO reading and writing data, Debugging message output, running status and transmitting-receiving message;
When communications protocol need be closed, close agreement IO data field earlier, nullify communications protocol then.
The content of said configuration data comprises: protocol name, protocol number, protocol analysis function pointer, agreement IO counts and agreement IO dot address distribution condition.
Specific in this example:
As shown in Figure 1; The data interval that interactive mode is employed in two communications more between existing communications protocol carries out the copy operation of data; Thisly operate in that agreement is few, be suitable under the simple situation of data structure; But increase along with communications protocol quantity and diversity are complicated, use will occur when carrying out data interaction between this agreement to agreement seriously rely on, functional check increases, the logical relation of several data intervals complicated, be not easy to problem such as transplanting.
Scheme among Fig. 2; All communications protocol are all passed through unified communication shared region data access interface and are conducted interviews; Operation is unitized, according to the corresponding relation between communication interface data field and agreement and the interface, distinguishes different data access authorities; Communications protocol can only be under its normal authority the visit data district, visit plays a very good protection to data; The consultative management function can realize the work coordination between agreement so that understand operating state each other between agreement simultaneously for the interface that the user provides consultative management; Because the isolation of agreement and data interval, agreement can be transplanted in the system in identical data sharing district at an easy rate.
As shown in Figure 3; Sharing data area comprises and the corresponding communication interface of agreement data field, communications protocol configuring area, Debugging message output area, running state information district that wherein the communication interface data field is divided into agreement IO data field and communication packet data field two parts again.Agreement IO data field comprises the IO point data corresponding with agreement, and the communication packet data field is to be used for the input and output message of memory communicating interface, gives over to the protocol-driven debugging and uses.
Step for the operation of communication sharing data area shown in Figure 4:
At first, startup accomplishes the parsing of system protocol configuration and writing of communications protocol configuring area when being provided; Agreement is registered startup one by one then; And open required communication interface data field, next be exactly the operations such as preservation renewal of carrying out communication, IO reading and writing data, Debugging message output, running status and transmitting-receiving message.Close the data field when agreement need be closed earlier, nullify agreement then, such as two of time-division operations even a plurality of communications protocol on a hardware interface.
