Embodiment
The base station is made of many veneers, and master control borad is preserved the software of whole base station, and when each veneer need carry out software upgrading, master control borad was sent to each veneer to software data, and write in the storage medium of each veneer.Because the processor that the veneer side adopts is lower with respect to the processor host frequency of master control borad side, disposal ability also is lower than master control borad, because the master control borad side is different with the disposal ability of veneer side, the master control borad disposal ability is better than veneer, therefore bottleneck occurred in the veneer side, this bottleneck can influence the data transmission efficiency of master control borad to veneer.The invention provides a kind of method and device of transmitting data between substation plates, to improve the data transmission efficiency of veneer side.Its core concept is to be divided into two relatively independent processes with reading the process of main control board data and process that data write storage medium, and the series process that reads in the prior art and write is changed into the parallel work-flow process.Below introduce implementation procedure of the present invention.
In order to realize this purpose, the invention provides a kind of method of transmitting data between substation plates, write the step that has increased in the middle of the process of storage medium the interim storage of data in the process that reads main control board data and data, promptly at first read main control board data and store temporarily; And then read the data of interim storage and write storage medium.Because buffer area will wait the data of storage medium to be written to store temporarily, therefore realized the parallel work-flow of read-write; Simultaneously; mistake does not appear when guaranteeing read-write in multi-task scheduling function and the semaphore defencive function of the present invention by the Semaphore Mechanism task; make regardless of the speed of writing storage medium; the efficient of accepting message can reach maximum; avoided the inconsistent efficiency that causes of data read and writing speed; save the stand-by period, thereby improved efficiency of transmission.
Simple in order to realize, realize the interim function of storing of data with buffer area in the present invention.
In addition, read in message in the present invention and also be provided with message between task and the storage medium and write task, be responsible for reading the data of interim storage in the buffer area and write storage medium; Only be used for reading the data of master control borad and be stored to buffer area and message reads task.When the veneer side joint was received the data that master control borad sends, message read task and constantly reads the data of coming from master control borad and write buffer area, and message writes task then constantly from the buffer area reading of data and write storage medium.
Simultaneously, after preventing data read and writing parallel work-flow, read-write order difference causes confusion, and provides two kinds of orders that guarantee that data are still read from master control borad according to data to write the method for memory block among the present invention, and concrete implementation step will describe in detail in conjunction with following two embodiment.
The present invention is divided into a plurality of sub-buffer areas with buffer area, because data deposit buffer area in and operation that data are taken out is read task and message by message respectively and write task and finish from buffer area among the present invention, therefore for same sub-buffer area, may occur that message reads task and message writes the situation that task is visited same sub-buffer area simultaneously, for the imperfect problem of the data that deposit storage medium in that prevents to cause in this case, the present invention reads task and message in message and writes and use the Semaphore Mechanism of operating system to guarantee the data write mutual exclusion between the task, promptly or message reads task run, or just write the storage medium task run.Semaphore Mechanism is the mechanism with the exclusive reference problem that solves shared resource.
Below be the detailed process of veneer side data transmission among the present invention:
Message reads the sub-buffer area that task at first finds does not have data, inquire about the semaphore of this sub-buffer area then, if semaphore shows that present message writes task and is not in the executable operations state, then successful picked up signal amount, otherwise, if this moment is because message writes task is in executing state and causes obtaining semaphore, then wait; After the picked up signal amount, message reads task the data of master control borad is write buffer area, and the signalization amount is for can read state.
After writing full this sub-buffer area, message reads task and continues data are write next sub-buffer area according to above-mentioned steps, all writes interim buffer area until the data with master control borad.
Message writes task writes buffer area according to data the data that call over, its process is: the semaphore that at first obtains this sub-buffer area, as in the fruit buffer area data being arranged, and show according to semaphore, message reads task not in operation at present, then successful picked up signal amount, otherwise, if can not get semaphore, then wait for.After obtaining semaphore, message writes task reading of data from this sub-buffer area, deposit data in storage medium, and the signalization amount is can write state.After the data that run through this sub-buffer area, the sequential read that writes buffer area according to data is got next data cached, until the data in the buffer area are all write storage medium.

Message reads task and writes data according to the sequence of addresses of each sub-buffer area, at first obtains the semaphore (step 1) of this sub-buffer area, judges whether this sub-buffer area has data (step 2); If write full data in this sub-buffer area, then wait for; If do not have data in this sub-buffer area, judging then whether present semaphore status is in can write state (step 3), if, be that message writes task not in operation, then successful picked up signal amount (step 4) writes data then, and the signalization amount is for can read (step 5); If can not get semaphore then wait for;
When this sub-buffer area write full after, message reads task will data cached next individual sub-buffer area according to the buffer area sequence of addresses, ablation process is as indicated above, repeats no more.
Message writes task and reads the buffer area data according to the sequence of addresses of sub-buffer area equally: from the first address of buffer area, at first obtain the semaphore of this buffer memory, if do not have data in this sub-buffer area, then wait for; If in this sub-buffer area data are arranged, and at present message reads task in operation, and then successful picked up signal amount reads data cachedly then, and the signalization amount is for writing; Otherwise, if can not get semaphore then wait for;
When reading this sub-data in buffer of sky, message writes task and reads next sub-buffer area data according to the buffer area sequence of addresses, all writes storage medium until the data with buffer area.
Second embodiment: in the present embodiment, one section buffer area is set equally at first, described buffer area is divided into a plurality of sub-buffer areas; Different with first embodiment, in the present embodiment, message reads task and when reading main control board data the data that read is numbered, for example, can search the sub-buffer area that does not have data then with main control board data according to numbering of section, at random write described sub-buffer area, message writes task and write calling over of buffer area originally according to data when reading the buffer area data, and promptly the numbering of data is read, to avoid data corruption.It hereinafter is detailed process.
Message reads task and according to the numbering of main control board data data is write buffer area, at first obtains the semaphore of this sub-buffer area, if write full data in this sub-buffer area, then waits for; If do not have data in this sub-buffer area, and its present semaphore status be in can write state, promptly message writes task in operation, then successful picked up signal amount writes data then, and the signalization amount is for reading; If can not get semaphore then wait for;
After this sub-buffer area has been write completely, message reads the sub-buffer area that the task stochastic searching next one does not have data, to write this sub-buffer area according to the data that the number order of main control board data is numbered the next one then, ablation process is as indicated above, repeats no more.
Message writes task and reads the buffer area data according to the number order of main control board data equally: number from the head of main control board data, at first obtain the semaphore of the sub-buffer area of this data cached correspondence, if do not have data in this sub-buffer area, then wait for; If in this sub-buffer area data are arranged, and at present message reads task in operation, and then successful picked up signal amount reads data cachedly then, and the signalization amount is for writing; Otherwise, if can not get semaphore then wait for;
When reading this sub-data in buffer of sky, message writes task and reads next data of numbering in the corresponding sub-buffer area according to data number, all writes storage medium until the data with buffer area.
In order to use the method for transmitting data between substation plates of the present invention, the present invention also provides a kind of device of transmitting data between substation plates, and Fig. 1 is the structural representation of this device.This device comprises and is used for data are sent to the master control borad 1 of veneer and the veneer 2 of reception main control board data.The message that comprises described veneer 2 reads TU task unit 3, temporary storage cell 4, message and writes TU task unit 5 and storage medium unit 6.
When veneer received master control borad 1 data, message read TU task unit 3 and reads from the data of master control borad and write described temporary storage cell 4, and message writes TU task unit 5 from described temporary storage cell 4 reading of data and write described storage medium 6.
In addition, described temporary storage cell 4 also comprises the semaphore protected location, writes the read-write mutual exclusion that TU task unit and described message read TU task unit to guarantee described message.
