[0044] Beneficial effect: In the management method of abnormal events of the electric energy meter provided by the present invention, first, the operating status of the electric energy meter is monitored in real time to obtain target monitoring information; wherein, the electric energy meter is a passive electric energy meter; when it is monitored that the electric energy meter loses power, it is determined whether an abnormal event occurs during the operation of the electric energy meter based on the target monitoring information; if so, a 1-bit storage unit in the electric energy meter is used to record the number of occurrences, occurrence time, event occurrence information, end time and event end information of the abnormal event and write them into the status of the electric energy meter, and the number of occurrences, occurrence time, event occurrence information, end time and event end information of the abnormal event are written into the storage space of the electric energy meter; when the electric energy meter is powered on again, the information recorded in each storage unit in the electric energy meter and the storage space of the electric energy meter are read respectively to restore the information corresponding to the abnormal event.

[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] See also Figure 1 , Figure 1 A flow chart of a method for managing abnormal events of an electric energy meter provided by an embodiment of the present invention, the method comprising:

[0054] Step S11: monitor the operating status of the electric energy meter in real time to obtain target monitoring information; wherein the electric energy meter is a passive electric energy meter;

[0055] Step S12: when it is detected that the electric energy meter loses power, it is determined whether an abnormal event occurs during the operation of the electric energy meter according to the target monitoring information; if so, step S13 is executed;

[0056] Step S13: using a 1-bit storage unit in the electric energy meter to record the number of occurrences, occurrence time, event occurrence information, end time and event end information of the abnormal event and write them into the state of the electric energy meter, and write the number of occurrences, occurrence time, event occurrence information, end time and event end information of the abnormal event into the storage space of the electric energy meter;

[0057] Step S14: when the electric energy meter is powered on again, the information recorded in each storage unit in the electric energy meter and the storage space of the electric energy meter is read respectively to restore the information corresponding to the abnormal event.

[0058] In this embodiment, a method for managing abnormal events of an electric energy meter is provided. This method can not only accurately record the information corresponding to the electric energy meter when an abnormal event occurs, but also avoid the problems of garbled information and errors that occur during the recovery process of the abnormal event.

[0059] The method is described with the processor in the electric energy meter as the execution subject. In this embodiment, the electric energy meter refers to a passive electric energy meter, that is, the electric energy meter does not contain a power supply. In the method, the operating state of the electric energy meter is first monitored in real time to obtain target monitoring information. Because the target monitoring information contains various operating state information of the electric energy meter, the operating state of the electric energy meter and whether the electric energy meter encounters an abnormal event can be determined based on the target monitoring information.

[0060] When power failure is detected in the electric energy meter, if it is determined that an abnormal event has occurred in the electric energy meter based on the target monitoring information, the 1-bit storage unit in the electric energy meter can be used to record the number of occurrences, occurrence time, event occurrence information, end time and event end information of the abnormal event and write them into the status of the electric energy meter, and the number of occurrences, occurrence time, event occurrence information, end time and event end information of the abnormal event can be written into the storage space of the electric energy meter.

[0061] The event occurrence information refers to the information corresponding to the energy meter when an abnormal event occurs, such as the voltage information, current information, power information, and operating condition information corresponding to the energy meter when the abnormal event occurs. The event end information refers to the information corresponding to the energy meter when the abnormal event ends, such as the voltage information, current information, power information, and operating condition information corresponding to the energy meter when the abnormal event ends.

[0062] It should be noted that when the electric energy meter loses power, the electric energy meter will record the relevant information of the abnormal event according to the following steps. That is, step 1: the processor will use a 1-bit storage unit to record the number of occurrences of the abnormal event and write it into the state of the electric energy meter, and then write the number of occurrences of the abnormal event into the storage space of the electric energy meter; step 2: the processor will use a 1-bit storage unit to record the occurrence time of the abnormal event and write it into the state of the electric energy meter, and then write the occurrence time of the abnormal event into the storage space of the electric energy meter; step 3: the processor will use a 1-bit storage unit to record the event occurrence information of the abnormal event and write it into the state of the electric energy meter, and then write the event occurrence information of the abnormal event into the storage space of the electric energy meter; step 4: the processor will use a 1-bit storage unit to record the end time of the abnormal event and write it into the state of the electric energy meter, and then write the end time of the abnormal event into the storage space of the electric energy meter; step 5: the processor will use a 1-bit storage unit to record the event end information of the abnormal event and write it into the state of the electric energy meter, and then write the event end information of the abnormal event into the storage space of the electric energy meter.

[0063] In addition, it should be noted that when the processor executes the above steps, the power stored in the electric energy meter may be exhausted. In this case, if the processor has just completed step 1 and has not yet executed step 2, the processor will not execute step 2 and its subsequent process steps.

[0064] It is understandable that because it takes less time to record a few bits of data than to record the data corresponding to the entire abnormal event, the method can accurately record the number of occurrences, occurrence time, event occurrence information, end time, and event end information corresponding to the abnormal event into the state of the electric energy meter. At the same time, in the process of recording the information related to the abnormal event, the state of writing the number of abnormal event occurrences into the electric energy meter is put first, so that the most important and critical information in the abnormal event can be stored in the electric energy meter, thereby ensuring the accuracy and reliability of the recorded information.

[0065] When the electric energy meter is powered on again, the processor will read the information recorded in each storage unit and the storage space of the electric energy meter respectively, and will recover the information corresponding to the abnormal event based on the read information. Through this data recovery method, the status information recorded in each storage unit can be used to determine whether the information written to the storage space of the electric energy meter is complete and accurate, so that the problem of garbled information and errors can be avoided in the process of recovering abnormal events.

[0066] In addition, when the method is used to recover abnormal events in the electric energy meter, it not only effectively solves the problems of garbled information and errors that occur when recovering abnormal events in the prior art, but also does not increase the cost required to recover abnormal events in the electric energy meter.

[0067] Based on the above embodiments, this embodiment further illustrates and optimizes the technical solution. Figure 2 , Figure 2 A flowchart for recording abnormal events in an electric energy meter provided by an embodiment of the present invention. As a preferred implementation, the above steps: using a 1-bit storage unit in the electric energy meter to record the number of occurrences, occurrence time, event occurrence information, end time, and event end information of abnormal events and write them into the state of the electric energy meter, and writing the number of occurrences, occurrence time, event occurrence information, end time, and event end information of abnormal events into the storage space of the electric energy meter, include:

[0068] Step S101: using the first storage unit in the electric energy meter to record the number of occurrences of abnormal events and write them into the state of the electric energy meter, and writing the number of occurrences of abnormal events into the first storage space of the electric energy meter;

[0069] Step S102: using the second storage unit in the electric energy meter to record the occurrence time of the abnormal event and write it into the state of the electric energy meter, and write the occurrence time of the abnormal event into the second storage space of the electric energy meter;

[0070] Step S103: using the third storage unit in the electric energy meter to record the event occurrence information of the abnormal event and write it into the state of the electric energy meter, and writing the event occurrence information of the abnormal event into the third storage space of the electric energy meter;

[0071] Step S104: determine whether the abnormal event is a delay event; if so, continue to execute steps S105 to S106; if not, end the process;

[0072] Step S105: using the fourth storage unit in the electric energy meter to record the end time of the abnormal event and write it into the state of the electric energy meter, and writing the end time of the abnormal event into the fourth storage space of the electric energy meter;

[0073] Step S106: Use the fifth storage unit in the electric energy meter to record the event end information of the abnormal event and write it into the status of the electric energy meter, and write the event end information of the abnormal event into the fifth storage space of the electric energy meter; wherein the storage space occupied by the first storage unit, the second storage unit, the third storage unit, the fourth storage unit and the fifth storage unit is 1 bit.

[0074] In this embodiment, the recording process of abnormal events in the electric energy meter is specifically described. Among them, the delayed event refers to the event that the electric energy meter has an abnormal situation and takes a long time to complete, not instantaneously, and will last for a period of time, such as: the overcurrent event, overvoltage event, and overpower event encountered by the electric energy meter. The non-delayed event refers to the event that the electric energy meter has an abnormal situation and is completed instantly, such as: the power failure event of the electric energy meter, etc.

[0075] It should be noted that when a non-delayed event occurs in the electric energy meter, the abnormal situation of the electric energy meter is completed in an instant. At this time, the occurrence time and end time of the abnormal event are the same, and the event occurrence information and event end information of the abnormal event are the same. In this case, when the processor records the relevant information of the abnormal event, it can either execute steps S101 to S103 in sequence; it can also execute steps S101, S102 and S106 in sequence; it can also execute steps 101, S104 and S105 in sequence.

[0076] Through the above process steps, the key information of each part of the abnormal event can be recorded in the electric energy meter in order of priority of the key information in the abnormal event, thereby accurately recording the relevant information when the electric energy meter has an abnormal event during power failure.

[0077] Obviously, the technical solution provided by this embodiment can ensure the accuracy and reliability of recording information related to abnormal events.

[0078] As a preferred implementation, the above step of using the first storage unit in the electric energy meter to record the number of occurrences of abnormal events and write them into the state of the electric energy meter, and writing the number of occurrences of abnormal events into the first storage space of the electric energy meter includes:

[0079] The state flag bit of the first storage unit in the electric energy meter is set to 1, so as to write the number of occurrences of abnormal events into the state of the electric energy meter for recording; wherein the storage space occupied by the state flag bit of the first storage unit is 1 bit;

[0080] Writing the number of occurrences of abnormal events into the first storage space of the electric energy meter, and updating the data stored in the first storage space;

[0081] When the data stored in the first storage space is updated, the status flag of the first storage unit is set to 0.

[0082] When recording the number of occurrences of abnormal events, the state flag of the first storage unit in the electric energy meter is first set to 1. The purpose of this operation is to use the state flag of the first storage unit to identify the number of occurrences of abnormal events and write it into the state of the electric energy meter.

[0083] When the status flag position of the first storage unit in the electric energy meter is set to 1, the number of occurrences of the abnormal event is written into the first storage space of the electric energy meter, and the data stored in the first storage space is updated. When the data stored in the first storage space is updated, the status flag position of the first storage unit is set to 0, so as to wait for the next abnormal event to be triggered.

[0084] Of course, here we only use the example of the processor recording the number of occurrences of abnormal events. According to the same method, the occurrence time, event occurrence information, end time and event end information of the abnormal event can be written into the status of the electric energy meter, and the occurrence time, event occurrence information, end time and event end information of the abnormal event can be written into the storage space of the electric energy meter for recording. I will not go into details here.

[0085] Obviously, through the method provided in this embodiment, the number of occurrences of abnormal events of the electric energy meter can be accurately recorded.

[0086] As a preferred implementation, the electric energy meter is further provided with a sixth storage space which is redundant with the first storage space.

[0087] Since the number of occurrences of abnormal events is the most critical information in the information related to abnormal events compared to other information of abnormal events, in order to ensure the accuracy and reliability of the recovery result when recovering the abnormal events, a sixth storage space that is redundant with the first storage space can also be set in the electric energy meter. That is, the sixth storage space is used to record the number of occurrences of abnormal events.

[0088] As a preferred implementation, the above step of respectively reading the information recorded in each storage unit and the storage space of the electric energy meter to restore the information corresponding to the abnormal event includes:

[0089] Reading the state identifier stored in the state flag bit of the first storage unit;

[0090] If the status flag bit of the first storage unit is set to 0, the data recorded in the first storage space is read to obtain the first read data, and the data recorded in the sixth storage space is read to obtain the second read data;

[0091] Verifying the first read data and the second read data;

[0092] If both the first read data and the second read data pass verification, determining the number of occurrences of the abnormal event according to the first read data to obtain a first read number, and determining the number of occurrences of the abnormal event according to the second read data to obtain a second read number;

[0093] Determine whether the first reading number and the second reading number are equal;

[0094] If yes, the first reading number or the second reading number is determined as the actual number of occurrences of the abnormal event;

[0095] If not, the maximum value of the first reading number and the second reading number is selected to obtain the target reading number, and the target reading number is determined as the actual number of occurrences of the abnormal event.

[0096] In the process of recovering the number of occurrences of abnormal events, the status identifier stored in the status flag of the first storage unit can be read first. If the status flag of the first storage unit is set to 0, it means that the data stored in the first storage space and the sixth storage space are complete. At this time, the data recorded in the first storage space and the sixth storage space are read respectively to obtain the first read data and the second read data.

[0097] Then, the first read data and the second read data are verified. If the first read data and the second read data pass the verification, it means that the first read data and the second read data have not been tampered with or missing. At this time, the number of occurrences of the abnormal event is determined based on the first read data and the second read data, respectively, to obtain the first read number and the second read number.

[0098] Afterwards, it is determined whether the first reading number and the second reading number are equal. If the first reading number and the second reading number are equal, the first reading number or the second reading number is determined as the actual number of occurrences of the abnormal event. If the first reading number and the second reading number are not equal, it means that one of the mutually redundant first storage space and the sixth storage space does not record the complete information of the number of occurrences of the abnormal event. At this time, the maximum value of the first reading number and the second reading number is determined as the actual number of occurrences of the abnormal event.

[0099] Obviously, through the technical solution provided in this embodiment, the number of occurrences of abnormal events can be accurately restored.

[0100] As a preferred implementation, the above step of respectively reading the information recorded in each storage unit and the storage space of the electric energy meter to restore the information corresponding to the abnormal event includes:

[0101] Reading the state identifier stored in the state flag bit of the first storage unit;

[0102] If the status flag of the first storage unit is set to 1, and it is determined based on the data recorded in the first storage space that the number of occurrences of the abnormal event has not been fully recorded, the record information corresponding to the abnormal event is restored based on the data recorded when the electric energy meter is powered on again.

[0103] In the process of recovering the information corresponding to the abnormal event, if it is found that the status flag of the first storage unit is set to 1, and the data written in the first storage space is not fully recorded, it means that the first storage unit has completed recording the status of writing the number of abnormal event occurrences into the electric energy meter, but the first storage space has not had time to fully record the number of abnormal event occurrences.

[0104] In this case, it is necessary to retain the status identifier stored in the status flag bit in the first storage unit, and restore the record information of the abnormal event according to the data recorded when the electric energy meter is powered on again.

[0105] Obviously, through the technical solution provided by this embodiment, the relevant information of the abnormal event can be accurately restored.

[0106] As a preferred implementation, the above step of respectively reading the information recorded in each storage unit and the storage space of the electric energy meter to restore the information corresponding to the abnormal event includes:

[0107] Reading the state identifier stored in the state flag bit of the first storage unit;

[0108] If the status flag of the first storage unit is set to 0, and it is determined based on the data recorded in the first storage space that the number of occurrences of the abnormal event has been completely recorded, it is determined that the record information of the abnormal event is lost.

[0109] In the process of recovering the information of abnormal events, if it is found that the status flag of the first storage unit is set to 0, and it is determined based on the data recorded in the first storage space that the number of occurrences of abnormal events has been completely recorded, it means that the number of occurrences of abnormal events recorded in the first storage space is the number of occurrences corresponding to the last abnormal event that occurred in the electric energy meter, and the number of occurrences of the latest abnormal event is written to the state of the electric energy meter but not stored in the first storage unit, and the time of occurrence of the latest abnormal event is not written into the first storage space of the electric energy meter. In this case, it is determined that the recorded information of the abnormal event is lost. That is, the electric energy meter does not record the latest abnormal event when the power is off.

[0110] Obviously, the technical solution provided in this embodiment can ensure the accuracy and reliability when recovering from abnormal events in the electric energy meter.
