Detailed Description

step 2, when the electric energy meter detects that an electric energy meter event occurs, the electric energy meter sends electric energy meter event information and operation data corresponding to the current state of the electric energy meter event to the concentrator; the electric energy meter event information comprises electric energy meter events and event status words corresponding to the electric energy meter events; the electric energy meter event can be an electricity utilization operation abnormal event or an electricity stealing event or a power failure event;
step 3, the concentrator analyzes the received event information of the electric energy meter and judges that the current electric energy meter event is in an effective state, the concentrator is switched to step 4, and the event pretreatment aiming at the current electric energy meter event is started; otherwise, the concentrator does not process the current electric energy meter event and finishes the reporting processing operation aiming at the current electric energy meter event; that is, once the concentrator determines that the current event of the electric energy meter is not in an effective state, the concentrator does not report the current event of the electric energy meter to the master station;
step 4, the concentrator acquires the electric energy meter event and the event state word in the analyzed electric energy meter event information, and preprocesses the acquired event state word according to a preset event queue data structure; the event queue data structure comprises electric energy meter event reporting time, an electric energy meter address corresponding to the electric energy meter event, an event state word corresponding to the electric energy meter event and the occurrence frequency of the electric energy meter event;
the events of the electric energy meter correspond to the event status words one by one; the reporting time of the electric energy meter event refers to the time when the concentrator receives the electric energy meter event; the occurrence frequency of the electric energy meter events refers to the sequence of the electric energy meter corresponding to the current electric energy meter events; for example, in the current electric energy meter a, the electric energy meter event occurring for the first time is the electric energy meter event a1, the electric energy meter event occurring for the second time is the electric energy meter event a2, the electric energy meter event occurring for the third time is the electric energy meter event A3, the number of occurrences of the electric energy meter event a2 is 2, and the number of occurrences of the electric energy meter event A3 is 3;
step 5, the concentrator establishes an event queue to be processed, and adds each preprocessed event status word into the event queue to be processed so as to wait for event reporting services to be processed uniformly;
the method comprises the steps that a preset electric energy meter event to be copied and read and a preset electric energy meter event not to be copied and read are placed in an event queue to be processed; the event of the electric energy meter to be read needs to be processed by the concentrator; the event of the electric energy meter which is not to be read does not need to be processed by the concentrator; it should be noted that the processing priority of the concentrator for the event processing service of the electric energy meter is higher than that of the concentrator for the ordinary collection service of the electric energy meter; that is, the concentrator processes the electric energy meter event preferentially, and then processes the common acquisition service aiming at the electric energy meter data;
in addition, aiming at the electric energy meter event which is not processed at the next time, the concentrator can process the electric energy meter event to be copied and read which is still in the effective state and is not processed by inquiring the event state word in the event queue to be processed again, so that the problem of loss of the electric energy meter event is avoided;
step 6, the concentrator judges that the electric energy meter event which is positioned in the event queue to be processed and needs to be processed is empty, the concentrator indicates that no electric energy meter event which needs to be processed by the concentrator exists at present, and the concentrator continues to receive the electric energy meter event sent by each electric energy meter;

step a2, the concentrator negates the taken event state word by bit, and performs packaging processing to obtain a packaged event state word message; for example, if the value of the event status word corresponding to one energy meter event is 0, the concentrator should invert the event status word with the value of 0 bit by bit, i.e. modify the value of the event status word from 0 to 1; of course, if the value of the event status word corresponding to an event of the electric energy meter is 1, the concentrator should invert the event status word with the value of 1 bit by bit, i.e. modify the value of the event status word from 1 to 0;
step a3, the concentrator sends the event status word message after the package processing to the electric energy meter;
step a4, after the electric energy meter successfully clears the corresponding event status word according to the event status word message, the electric energy meter sends a successfully cleared feedback information message to the concentrator, and the step a5 is switched to; otherwise, the electric energy meter sends a feedback information message which is not successfully cleared to the concentrator, and the step a7 is carried out;
that is, if the electric energy meter event corresponding to the event status word message sent by the concentrator is B1, after the electric energy meter receives the event status word message sent by the concentrator and corresponding to the electric energy meter event B1, the electric energy meter clears the event status word existing in the electric energy meter event B1 of the electric energy meter, and then after the electric energy meter ensures that the event status word is successfully cleared, the electric energy meter sends a feedback information message of successful clearing to the concentrator;
a5, the concentrator receives the feedback information message which is successfully cleared and sent by each electric energy meter, and analyzes the received feedback information message which is successfully cleared;
step a6, after the concentrator successfully analyzes and clears the feedback information message successfully, the current clearing event state operation aiming at the electric energy meter event is ended;
step a7, the concentrator sends the command of clearing the event status word message to the electric energy meter again, the electric energy meter repeatedly executes the clearing operation aiming at the current event status word message command within the preset times, and the current clearing operation aiming at the event status word is finished after the electric energy meter successfully executes the event status word clearing operation;
and 8, after the concentrator receives the successfully-cleared feedback information sent by the corresponding electric energy meters, the concentrator restarts event collection operation aiming at the event state words of the electric energy meters corresponding to all the electric energy meters:
8-1, the concentrator analyzes an event state word corresponding to an electric energy meter event sent by the electric energy meter;
step 8-2, the concentrator judges whether the event data of the electric energy meter needs to be read according to the analyzed event state word:
when the concentrator judges that the analyzed electric energy meter event is a preset electric energy meter event to be copied, the concentrator takes out each data item of the electric energy meter event corresponding to the event state word according to a preset event queue data structure, and the step is switched to the step 8-3; the data items are data in an event queue data structure and mainly comprise electric energy meter event reporting time, an electric energy meter address corresponding to an electric energy meter event, an event state word corresponding to the electric energy meter event and the occurrence frequency of the electric energy meter event;
when the concentrator judges that the analyzed electric energy meter event is a preset non-to-be-read electric energy meter event, the concentrator reports an event state word message corresponding to the current electric energy meter event to the master station, and finishes the operation of collecting the event of the electric energy meter corresponding to the current event state word;
8-3, when the concentrator judges that the number of the data items corresponding to each analyzed event state word is more than zero, the concentrator requires each electric energy meter to package and send each data item in the electric energy meter, so that the electric energy meter sends the packaged data including the data items to the concentrator; otherwise, turning to the step 8-5;
step 8-4, the concentrator receives and analyzes the packet data sent by the electric energy meter, and caches the received electric energy meter event original message in a concentrator memory;
and 8-5, the concentrator reports the cached original message of the electric energy meter event to the master station, and finishes the operation of collecting the event aiming at each electric energy meter.
Of course, after the concentrator finishes processing the electric energy meter event, the concentrator assigns a processed state identifier to the electric energy meter event which is located in the event pending queue and is finished processing.
In order to save the memory of the concentrator, the active reporting and processing method for the electric energy meter events in this embodiment also limits the number of electric energy meter events permitted to be processed by the concentrator. For example, the number of meter events permitted to be processed by the concentrator is limited to 16.
In addition, different electric energy meter event processing priorities can be given to the electric energy meters in the electric power system, and the concentrator processes the electric energy meter events sent by the corresponding electric energy meters according to the priority of the given electric energy meter event processing priorities. Of course, the master station may also send a preset event reporting time point to the concentrator as needed, and the concentrator reports the processed electric energy meter event original message to the master station at the preset event reporting time point.
