Based on the hardware structure, the invention provides various embodiments of the load record generation method of the electric energy meter.
The invention provides a load record generation method of an electric energy meter.
Referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of a load record generation method of an electric energy meter according to the present invention.
In this embodiment, the load record generating method of the electric energy meter includes:
step S10, when detecting that the electric energy meter enters a test mode, acquiring first current time of the electric energy meter;
in the existing load record generation scheme, an external host is communicated with an electric energy meter, and the time of the electric energy meter is modified to generate a load record. The time required for generating one load record by the scheme at least needs 3 seconds, and the method specifically comprises the following steps: first, the process of communicating the external host with the power meter takes 1-2 seconds. The process comprises the steps that an external host generates a time modification command message, the external host sends the time modification command message to the electric energy meter through a communication port of the electric energy meter, the electric energy meter receives the command from a communication port drive receiving cache and analyzes and executes the time modification command, the time of the electric energy meter is modified to the time specified by the command, and the electric energy meter constructs a response message and sends the response message to the external host. Secondly, the command of changing the time of the external host can only change the time to 59 seconds of the previous 1 minute of the next freezing point, and the electric energy meter needs to run for at least 1 second to reach the next freezing point to generate a load record. For example, the next freezing point is 2020, 7, 20, 13 and 00, the external host can only issue a time change command to change the electricity meter to 59 in 2020, 7, 20, and 12, and the external host needs to run for 1 second to 13 in 2020, 7, and 20, 00 to freeze and generate a load record.
Since the calibration standard for load records is generally 28800 load records, if one load record calculation is generated in 3 seconds, 28800 load records require 86400 seconds, namely 1 day. And even if the meter time is changed at such a frequency, such a test cannot guarantee that every time change command is received and successfully responded to by the power meter, since every external communication is not reliable.
Therefore, the existing load record generation scheme takes a long time, and in addition, the time actually required to generate the load record may be longer due to unreliable external communication. Moreover, the communication is unsuccessful, which results in the loss of the load record at some time points, which is extremely disadvantageous for the verification of the subsequent load record.
Therefore, the technical scheme provided by the invention can directly acquire the current time after the electric energy meter enters the test mode by rewriting the software program, determine the generation time sequence of the load record according to the current time, further sequentially adjust the time of the electric energy meter to each generation time point in the generation time sequence, and freeze the target data of the electric energy meter at the adjusted generation time point to generate the load record. Through the mode, automatic generation of load records can be realized, the scheme in the embodiment of the invention does not need to communicate with an external host, the generation time only depends on the adjustment interval time, if the time of the electric energy meter is adjusted every 100ms, one record can be generated every 100ms, and 28800 records can be generated only in 2880 seconds (28800 x 100ms =2880 seconds), namely 48 minutes. In addition, the scheme of the embodiment of the invention does not need to communicate with an external host, so that the condition that the load records of partial time points are missed due to unreliable communication in the prior art can be avoided.
The load record generation method of the electric energy meter of the embodiment is realized by the electric energy meter. In this embodiment, when it is detected that the electric energy meter enters the test mode, the current time of the electric energy meter is obtained, and is distinguished from the subsequent current time of switching to the normal mode, and the current time is recorded as the first current time.
Step S20, determining a first generation time sequence of the load record according to the first current time and a preset rule;
then, a first generation time series of the load records is determined according to the first current time and a preset rule. Specifically, an initial generation time point may be determined according to the first current time, and then the first generation time series of the load record may be determined based on the initial generation time point and a preset rule. The generation time point of the load record is a time point which can be divided by the load record storage interval, and if the load record storage interval is 15 minutes, the generation time point of the load record is 4 time points of 0 minute, 15 minutes, 30 minutes and 45 minutes per hour. The preset rule may be preset based on a calibration standard of the electric energy meter, and includes a detection frequency and a detection number, for example, the calibration standard is to freeze data every 15min and calibrate 28800 records, and correspondingly, the detection frequency may be set every 15min, and the detection number is greater than or equal to the calibration number (greater than this, in order to avoid the situation that load records are obtained without freezing, and the total number of the load records cannot reach the calibration number).
For example, taking the above criteria as an example, if the first current time is 2020 and 7, 20 and 12, then the initial generation time point is determined to be 2020-7 to 20-00: 2020-7-20 13.
And S30, sequentially adjusting the time of the electric energy meter to each generation time point in the first generation time sequence, and freezing target data of the electric energy meter at the adjusted generation time point to generate a load record.
Then, the time of the electric energy meter is sequentially adjusted to each generation time point in the first generation time sequence, and target data of the electric energy meter at the adjusted generation time points are frozen to generate a load record. Wherein, the data to be frozen is the data of the related object, such as voltage, and can be specifically set according to the verification requirement; the load record includes the point in time of generation and its target data.
Of course, it can be understood that, in a specific implementation, the first generation time sequence may not need to be generated at one time, the time of the electric energy meter may be adjusted to the initial generation time point, after the corresponding load record is obtained, the next generation time point is determined (the next generation time point is the current time plus load record storage interval), and then the time of the electric energy meter is adjusted to the next generation time point, so as to obtain the corresponding load record, and so on, so as to obtain the load record of each generation time point.
The embodiment of the invention provides a load record generation method of an electric energy meter, which comprises the steps of acquiring first current time of the electric energy meter when the electric energy meter is detected to enter a test mode; then, determining a first generation time sequence of the load record according to the first current time and a preset rule; further, the time of the electric energy meter is sequentially adjusted to each generation time point in the first generation time sequence, and the target data of the electric energy meter at the adjusted generation time points is frozen to generate the load record. By the mode, automatic generation of the load record can be realized, the scheme in the embodiment of the invention does not need to communicate with an external host, and the generation time only depends on the adjustment interval time, so that the time for generating the load record can be greatly saved, and the generation efficiency is improved. In addition, the condition that the load recording of partial time points is lost due to unreliable communication in the prior art can be avoided.
Further, based on the first embodiment described above, a second embodiment of the load record generation method of the electric energy meter of the present invention is proposed. Referring to fig. 3, fig. 3 is a schematic flow chart of a load record generating method of an electric energy meter according to a second embodiment of the present invention.
In this embodiment, the load record generating method further includes:
step S40, when a test mode exit instruction is received, switching the running mode of the electric energy meter to a normal mode;
in this embodiment, when the test mode exit instruction is received, the operation mode of the electric energy meter is switched to the normal mode.
Step S50, acquiring second current time of the electric energy meter, and determining a second generation time sequence of the load record according to the second current time and the preset rule;
and then, acquiring the current time of the electric energy meter in the switching mode, distinguishing the current time from the current time of the electric energy meter in the switching mode, recording the current time as second current time, and then determining a second generation time sequence of the load record according to the second current time and a preset rule. The process of determining the second generated time sequence is consistent with the process of determining the first generated time sequence, and reference may be made to the first embodiment, which is not described herein again.
Step S60, acquiring real-time of the electric energy meter, and freezing target data of the electric energy meter at any generation time point in the second generation time sequence when the real-time is detected to be any time point in the second generation time sequence so as to generate a load record.
And further, acquiring the real-time of the electric energy meter, and freezing the target data of the electric energy meter at any generation time point in the second generation time sequence when the real-time is detected to be any time point in the second generation time sequence so as to generate a load record.
Specifically, when detecting whether the real-time is a certain time point of the second generated time sequence, the real-time of the electric energy meter may be compared with a first generated time point (a generated time point arranged at a first position) in the current second generated time sequence, and if the comparison is successful (i.e., the real-time is the same as the first generated time point), the first generated time point may be deleted to update the second generated time sequence, so as to facilitate subsequent comparison; if the comparison fails, whether the real-time point is smaller than the first generation time point can be detected, if so, the real-time of the electric energy meter is continuously acquired, if so, whether the real-time point is smaller than a second generation time point in the current second generation time sequence is continuously detected, and if not, the first generation time point is deleted to update the second generation time sequence so as to facilitate subsequent comparison.
In addition, in the present embodiment, the load record is generated from the generation time point obtained by matching and the target data corresponding to the generation time point.
In this embodiment, when the operation mode of the electric energy meter is switched to the normal mode, a corresponding second generation time sequence is generated, the real-time of the electric energy meter is acquired, and when it is detected that the real-time is any time point in the second generation time sequence, the target data of the electric energy meter at any generation time point in the second generation time sequence is frozen to generate the load record. By the mode, the load record under the normal mode of the electric energy meter can be automatically generated.
Further, based on the first and second embodiments described above, a third embodiment of the load record generation method of the electric energy meter of the present invention is proposed.
In this embodiment, the load record generating method further includes:
and step A, when the switching of the operation mode of the electric energy meter is detected, clearing the historical load record of the storage area so as to store the generated load record into the cleared storage area.
In this embodiment, when it is detected that the operation mode of the electric energy meter is switched, that is, the test mode is switched to the normal mode or the normal mode is switched to the test mode, the historical load record of the storage area may be cleared, that is, the load record generated in the previous mode is cleared, and then the load record generated in the current mode is stored in the storage area after the clearing.
By the method, the load data generated in the previous mode can be prevented from being mixed with the load data generated in the current mode, so that the accuracy of the subsequent data detection result and the accuracy of the verification result of the load record can be ensured.
Further, based on the first embodiment described above, a fourth embodiment of the load record generation method of the electric energy meter of the present invention is proposed.
In this embodiment, after the step S30, the method further includes:
step B, acquiring the number of current load records in real time, and detecting whether the number reaches a preset threshold value;
in this embodiment, the number of current load records is obtained in real time, and whether the number reaches a preset threshold is detected, where the preset threshold is preset based on the calibration standard of the electric energy meter, that is, the number is calibrated 28800 times.
If the number reaches a preset threshold, executing the step C: and executing load record verification operation.
If the number reaches a preset threshold value, the load record is generated completely, and at the moment, the load record verification operation can be executed, namely self-verification is carried out.
Specifically, the step C includes:
step C1, acquiring an initial time point from the first generation time sequence as a target time point;
step C2, generating a record searching command according to the target time point, and inquiring the load record according to the record searching command to obtain an intermediate inquiry result;
in this embodiment, an initial time point is obtained from the first generation time sequence as a target time point; and then, generating a record searching command according to the target time point, and inquiring the load record according to the record searching command to obtain an intermediate inquiry result. In the query, it is queried whether the load record corresponding to the target query time in the record search command exists or not, and whether the data of the load record exists or not, and certainly, it may also be detected whether the data meets the preset requirement or not, and the intermediate query result may be a query success or a query failure.
As an implementation, during the query, the query program may be rewritten, and then the load record may be queried according to the record search command, so as to obtain an intermediate query result.
As another embodiment, step C2 includes:
step C21, the record searching command is put into a communication port drive cache of the electric energy meter so as to start a load recording module of the electric energy meter to perform record query;
and step C22, inquiring the load record through the load record module according to the record searching command to obtain an intermediate inquiry result.
As another embodiment, during query, the record searching command is put into a communication port drive cache of the electric energy meter to start a load recording module of the electric energy meter; and then, querying the load record through a load record module according to the record searching command to obtain an intermediate query result. By the method, the query program does not need to be rewritten, only the code for placing the record searching command into the communication port drive cache of the electric energy meter needs to be added, and the code of the query part can be used for prolonging the original code, so that the development efficiency can be improved, the development time can be saved, and the ROM and RAM resources of the electric energy meter processor can be saved.
Step C3, sequentially obtaining next time points from the generated time sequence as the target time points, and executing step C2: generating a record searching command according to the target time point, inquiring the load record according to the record searching command to obtain an intermediate inquiry result until the load record is inquired in a traversing way to obtain a final inquiry result, and by the mode, traversing verification can be completed on all 28800 records, and if the 28800 records are inquired in a master station terminal communication mode, at least 28800 times of communication is needed, so that the verification time of the 28800 records can be greatly saved, and the test efficiency is improved.

That is, the generation time points of the first generation time series are sequentially acquired, and the corresponding record search command is generated for searching.
Of course, it will be appreciated that the self-assay protocol described above is equally applicable to the normal mode.
In this embodiment, a record search command is automatically constructed, the constructed record search command is placed in a communication port drive cache of the electric energy meter, a message of a load record data reading command read by the master station is simulated, and all load records are searched in a protocol manner to obtain a query result, so as to verify whether the load records meet requirements. By the aid of the method, automatic verification of the load record can be realized, verification time can be greatly saved and verification efficiency is improved compared with a method of performing verification through external communication.
