Below in conjunction with accompanying drawing, describe the specific embodiment of the present invention in detail.
Metering data system for transmitting provided by the invention in system, comprises main harvester, or an individual standby harvester of N (N 〉=2) and a charge system used as shown in Figure 5, and a plurality of service processors also can a shared harvester.
Of the present invention as follows to the metering data transmission method of gathering from service processor:
Service processor has disposed main harvester, an one or more standby harvester used, and a plurality of service processors also can a shared harvester.After service processor produces metering data, send with harvester, use " transmission → wait acknowledge → overtime repeating transmission " mechanism to main; Main with harvester use " verification → receive → reply " mechanism, echo reply message after receiving metering data, the metering data of receiving can be transferred to BS and handle; Service processor is received in the time of setting and is mainly replied this process of transmitting end with harvester.Transmission can walk abreast and carry out, and promptly once sends and does not receive as yet when replying, and just can carry out the next one and send, and is full up to sending buffering area, and each the transmission uses different serial numbers to distinguish, and has the serial number of paid-in metering data correspondence in the response message.
If service processor is after through the time of setting, do not receive main response message with harvester, can resend this metering data, if do not receive main response message (among the present invention all service processors have been sent to lead with harvester but do not receive that the metering data of replying is called " metering data that may repeat (transmission) ") yet with harvester, can think main lost efficacy with harvester, metering data transfers to send to standby harvester, and comprise that step is as follows this moment:
1. send " shaking hands " message to standby harvester, whether normal with being connected of standby harvester to confirm, whether standby harvester work is normal;
2. standby harvester returns " shake hands and reply " message;
3. service processor will send to and lead with harvester but do not receive that the metering data of response message sends to guest machine by sending " may repeat the metering data of (transmissions) " message;
4. standby harvester receives " may repeat the metering data of (transmission) ", be kept in (independent) repetition buffering area, temporarily be not transferred to BS and handle, and echo reply message, described " metering data that may repeat " corresponding serial number comprised in the response message;
5. service processor will receive that the serial number of the metering data that standby harvester is replied notes.
On the one hand with all send to main with harvester but do not receive that the metering data of replying sends to spare processor, on the other hand new metering data (being referred to as " normal billing data " among the present invention) is directly sent to standby harvester, after standby harvester is received new metering data, the serial number that record is corresponding, this metering data is sent to BS, and echo reply message, comprise corresponding serial number in the response message.Simultaneously, service processor timing or not timing send " shaking hands " message to main with harvester, whether detect the master resumes work with harvester, after the master resumes work with harvester, can return " shaking hands " response message, after this, service processor then no longer sends to standby harvester, new metering data is issued the main harvester of using, adopt multiple inquiry mechanism simultaneously, promptly main with harvester but do not receive and reply and send to the metering data of standby harvester to issuing in the past, inquire about it with harvester and whether receive to leading, specifically may further comprise the steps:
6.1 service processor is inquired about to main the serial number of " metering data that may repeat " of above-mentioned preservation with harvester;
6.2 if the master receives that with the metering data that harvester returns this serial number correspondence then service processor is to the message of the metering data of standby this serial number correspondence of harvester transmission deletion, the metering data deletion of the correspondence that standby harvester is preserved;
If 6.3 the master does not receive that with the metering data that harvester returns this serial number then service processor is to the message of the metering data of standby this serial number of harvester transmission release, the metering data of the correspondence that standby harvester will be preserved is transferred to BS and handles.
Fig. 1-1 shows the message structure that the charging transfer of data sends among the present invention, two kinds of message structure forms are arranged: using form one when sending the metering data that the normal billing data maybe may repeat, promptly transmission command context wherein is respectively " sending the normal billing data " and " metering data that transmission may repeat ", serial number is the unique identifier (Identity of each metering data message, be called for short ID), the message of form one is carried metering data; Form two inquiry main whether receive metering data and send with harvester to standby harvester use when deletion/release may repeat metering data, sending command context is respectively " inquiry ", " deletion ", " release ", and message is carried the serial number of the metering data message that needs inquiry/deletion/release.
Fig. 1-2 is the message structure that the metering data transmission is replied, for the message of receiving that contains " transmission normal data ", " data that transmission may repeat ", " deletion ", " release " transmission order, response result is " successfully receiving ", for containing the message that " inquiry " sends order, according to the actual conditions response result may be " metering data of inquiry receives " or " metering data of inquiry does not receive ", carries the corresponding serial number that sends message in the message structure that the metering data transmission is replied.
Fig. 2 is the handling process that service processor sends data, and as shown in the figure, at first execution in step 200, service processor judges at first whether the master interrupts with harvester, if interrupt then execution in step 210, whether the timed sending handshake information recovers operate as normal to detect the master with harvester; If do not interrupt, execution in step 220, check whether service processor sends buffering area is empty, if be empty, represent that no metering data needs to send, directly return, if be not empty, promptly send metering data to be sent is arranged in the buffering area etc., execution in step 221, take out a bag metering data,, then directly send if these data are new data, if these data were for sending, then execution in step 222, and at first check in its repeating transmission time that whether surpasses setting and still do not receive response message, if not, then continue to wait for, do not send, if, execution in step 223, judge to retransmit number of times and whether surpass the repeating transmission number of times set (the repeating transmission number of times of setting can be 1 time or repeatedly), if not, execution in step 224, metering data sends with harvester to current master, send number of times and add 1, if when being checked through this metering data and retransmitting number of times above the restriction of set point, execution in step 230 judges whether that standby harvester working properly is in connection status, if have, execution in step 231, it is set to current harvester, and sends to this standby harvester issuing main data with harvester as the metering data that may repeat to send.This process flow loops is carried out.
After service processor receives the response message that harvester sends, flow process by Fig. 3 is handled, at first execution in step 300, judge whether this response message leads " shaking hands " response message of returning with harvester, if response message is " shaking hands " response message, execution in step 311, judge the response message of receiving of sending with harvester of shaking hands of whether leading, if not processing finishes, if, execution in step 312, judge whether the main of service processor record is interruption with the current state of harvester, if show that the master has recovered operate as normal with harvester, continue execution in step 313, the master is set to current harvester with harvester, execution in step 314, and whether service processor sends to the master to the serial number that repeats buffering area and receives with inquiry " metering data that may repeat to send " with harvester.If response message is not " shaking hands " response message, execution in step 321, judge whether the transfer of data response message, promptly to the replying of " transmission normal data ", " data that transmission may repeat ", if, execution in step 330, " transmission normal data " transmits response message whether to judge this response message, if, execution in step 332, with the metering data deletion of the transmission success of the serial number correspondence that comprises in the described response message, process of transmitting finishes service processor from send buffering area; If not execution in step 331, response message are that service processor is saved in the serial number of this metering data in the repetition buffering area to the replying of " data that transmission may repeat " message, execution in step 332 then, with the metering data deletion that sends in the buffering area; If not transfer of data response message, execution in step 322, the response message of " data of inquiry are received " (data are " data that may repeat (transmission) ") of whether judging this response message, if, execution in step 325, its serial number is issued standby harvester, notify its deletion the corresponding metering data that repeats to send, if not, execution in step 323, notify standby harvester to discharge this metering data, transfer of data is handled to BS; Execution in step 324 then, the serial number in the repetition buffering area that the deletion processor is preserved.
Gathering pusher side mainly is to receive the message that service processor sends, and returns suitable response message, and it is as follows that it handles thinking: at any time harvester has been received the handshake information of service processor, all can send the response message of shaking hands and respond.After harvester is received the normal billing data, it is transferred to BS handles, in the serial number buffering area, note its serial number simultaneously, send the response message that successfully receives to service processor.The serial number buffering area can be preserved the serial number of the metering data of receiving in nearest a period of time, whether be used to inquire about serial number repeats, when receiving query messages, just in the serial number buffering area, search, if find, the metering data that this serial number correspondence then is described successfully receives, otherwise does not receive, and sends corresponding response message.If what harvester was received is the metering data that possible repeat, then it can be sent to BS and handle, but be kept at earlier in the possibility repeating data buffering area, products for further is handled.After service processor is sent deletion message, just,, repeat the data dump in the buffering area if release message then is sent to corresponding data BS and handles with the data deletion of corresponding serial number in the repeating data buffering area.Specifically in conjunction with the accompanying drawings 4, implementation is: execution in step 400, harvester receives the message of service processor, judge whether handshake information, if execution in step 401 sends the response message of shaking hands and responds, otherwise, execution in step 410 judges whether to comprising the message of normal billing data, if, execution in step 411, it is transferred to BS handles, execution in step 412 is noted its corresponding serial number in the serial number buffering area simultaneously, execution in step 413 sends the response message that successfully receives to service processor; If not comprise the message of normal billing data, execution in step 420, judge whether to comprise the message that may repeat (transmission) metering data, if, execution in step 440, may repeat (transmission) metering data and be kept in the data buffer zone, and execution in step 441, the response message that successfully receives sent to service processor; If not comprise the message that may repeat (transmission) metering data, execution in step 421 judges whether to comprise the message of the data that inquiry may repeat, if, execution in step 430, judge the serial number whether the data correspondence that may repeat that will inquire about is arranged in the serial number buffering area, if execution in step 432 is arranged, send and accepted response message, otherwise execution in step 431 sends and does not accept response message; If not comprise the message of the data that inquiry may repeat, execution in step 422, judge whether to comprise the message of the data that deletion may repeat, if, execution in step 423, the metering data that deletion repeats to send from the data buffer zone that may repeat, execution in step 425 sends and successfully receives response message; If neither comprise the message of the data that deletion may repeat, execution in step 424 is sent to BS with the metering data in may the repeating data buffering area, and execution in step 425 sends and successfully receives response message.
Although the disclosed method and system that relates to the metering data transmission has been carried out special description with reference to embodiment, those skilled in the art can understand, under the situation that does not depart from scope and spirit of the present invention, can carry out all conspicuous modification of form and details to it.Therefore, embodiment described above is illustrative and not restrictive, and under the situation that does not break away from the spirit and scope of the present invention, all variations and modification are all within the scope of the present invention.
