In addition, the load input unit 130 manages the wiring in a wiring sequence, and when the three-phase wiring is normal, by changing and controlling the sequence 1-2-3 to 1-3-2, it is possible to automatically carry out a erroneous test that must be performed manually. have.

The process operation unit 120 controls and manages process operation steps for parallel processing while performing serial communication such as RS232 or RS422 / RS485 for communication and control between the electricity meters 110a... 110n and the load input unit 130. . In this case, the process operation unit 120 may be mounted on a desktop or a PC.

To this end, the process operation unit 120 includes a communication control unit 121, an analysis processing unit 122, a storage conversion unit 123, a process management unit 124, and a comparison determination unit 128 as shown in FIG. 5. can do.

The communication control unit 121 collects measurement information of the electricity meters 110a... 110n while automatically controlling the electricity meters 110a... 110n and the load input unit 130. At this time, the communication control unit 121 controls the load input unit 130 to automatically supply and cut off the load to the electricity meters (110a ... 110n) and to set the information required to set the test items in the electricity meters (110a ... 110n) DLMS ( Device Language Message Specification: IEC62056, an international standard adopted as a remote metering protocol in KEPCO low voltage meters.

The analysis processor 122 analyzes and processes the frames of the collected measurement information. The analysis processing unit 122 assembles and disassembles the collected information frames to analyze and process based on the DLMS protocol system.

The storage conversion unit 123 converts and stores the analyzed and processed measurement information according to the data type.

The process manager 124 manages process tests based on the structure of the master 111 and the slaves 112... To this end, as shown in FIG. 6, the present invention manages the process of the master to control the electricity meters 110a. A slave processor 126 constituting the slave table and a scheduling unit 127 for scheduling the process operation step, based on the master table and the slave table.

In this way, one master process unit 125, M slave process unit 126 and the scheduling unit 127 is provided to separate the process for each wattmeter (110a ... 110n), a problem in the process test of one wattmeter In the event of a failure, test the process of the other meter. In this case, the master processor 125 performs a complex and important function such as generating, terminating, scheduling, and managing slave processes by the number of connected power meters 110a... 110n, and the slave processor 126 performs the master processor ( It performs a relatively simple function of executing and managing process tests of the corresponding electricity meters 110a... 110n, such as a status response to the request of 125).

The slave processor 126 records a separate slave table for each step. The slave processor 126 records and manages the electricity meter ID, slave ID, and result information in the slave table as shown in FIG. 9.

This will be described later in detail.

The comparison determination unit 128 compares the result values before and after the process test process to determine suitability. The comparison determiner 128 compares the result values before and after the process test and determines the suitability through a suitability determination algorithm, thereby reducing the possibility of an error caused by manpower when operating or determining dozens of process test steps.

7 is a diagram illustrating a process operating method for parallel processing of a power meter according to an embodiment of the present invention.

The process test step according to the process operation unit 120 is processed into load input-information collection before the test-setting information change-test execution-information collection after the test-load blocking.

First, in the load input step (S100), load values for power and phase, power input time information for connection setting are input, and input initial TOU program information and the like. After the test information collection step (S200) to collect the information before the test to generate a reference value to compare and analyze the results after the test. In the setting information changing step (S300), the current, phase, duration, TOU program and power meter (110a… 110n) setting information, etc. are changed according to the test scenario, and then the test is performed according to the test scenario in the test execution step (S400). To perform. In the next information collection step after the test (S500) to collect the information after the test. This process test step performs the test by repeating the step of collecting information after changing only the simple setting information according to each step for each test item, and releases the connection through the load blocking step (S600) which is the final step.

8 is a view for explaining in detail the performing step of the electricity meter according to the process operating method for parallel processing of the electricity meter according to an embodiment of the present invention.

Looking at the process operation steps of the electricity meter based on the master and slave structure when performing the process test described above, the master 111 requests the corresponding states from the M slaves 112... 115 and the sles are each of the electricity meters 110a. In response to the request and response to the command of the master 111 in response to the master (111). In this case, the master 111 checks the received response and if all is normal, proceeds to the next step of the test step and performs an algorithm when there is no response or failure in some of the M power meters 110a ... 110n and proceeds to the next step. Detailed steps thereof will be described with reference to FIGS. 8 to 11.

In more detail, first, according to a test step and scheduling, when the load is input (S100), the master 111 requests M slaves 112 ... 115 managing M power meters 110a. After receiving the response to the ready state and proceeding to the next step (S200) after checking the response, when changing the setting information (S300), the master requests M slaves (112… 115) for the setting state and receives a response to the setting state. After confirmation, the next step proceeds, during the test execution, the master 111 requests execution instructions from the M slaves 112 ... 115, receives a response to the test execution (S400), and proceeds to the next step (S500) after confirming the response, collecting information. When the master 111 requests M slaves 112 to 115 for the collection state (S500), receives a response to the collection state, checks the response, and then proceeds to the next step (S600). To slaves 112… 115 Request for and receive a response to the release state (S600).

FIG. 9 is a diagram for describing slave table information according to a process operating method for parallel processing of power meter according to an embodiment of the present invention, and FIG. 10 is a process operating method for parallel processing of power meter according to an embodiment of the present invention. It is a figure for demonstrating master table information.

Referring to FIG. 9, the slave process records information generated at each step in the slave table. At this time, the slave table records and manages the electricity meter ID, slave ID, and result value information. In this case, Result may be recorded as one of 'P' successful, 'F' failed, and 'T' as a result value after data transmission and reception between the electricity meters 110a... 110n and the load input unit 130.

Referring to FIG. 10, the master process adds information such as Test Item1 (Test Item Large Classification), Test Item2 (Test Item Subclass), Process Index, and Retry number to the slave table to record the Master Table. In this case, 'L' in the process index is a load setting step, 'M' is a electricity meter setting step, 'A' is an execution step, and 'I' is an information collecting step.

The master process checks the table information from the response of the slaves 112... 115 to proceed to the next step or retry step. The table information check can be performed as follows.

1.If Result = ‘P '(success), proceed to next step (record P flag)

2.If Process Index = 'L' (Load Setting Step), 'M' (Power Meter Setting Step), 'A' (Step) and Result = 'F' (Fail), 'T' (Timeout), Retry normal setup and proceed to next step

3. If Process Index = 'I' (information gathering step) and Result = 'F' (failure) or 'T' (time out), proceed to next step (record F, T flag)

Referring to the drawing, when the process index is 'L' and 'M' during Test N, the retry algorithm is applied to the electricity meter 3 and the electricity meter 4 having the results of 'F' and 'T' respectively, whereas the process index is 'I'. If is, go to the next step. In other words, if it is an important item in the test phase by placing information such as process index (Process Index = 'L'-load setting step, 'M'-electricity meter setting step, 'A'-execution step), automatic test step through retransmission algorithm Improvements in testing phases, such as progress, can lead to more efficient test systems.

 FIG. 11 is a diagram for describing a method of operating a process for parallel meter processing based on recording table information configured as shown in FIGS. 9 and 10.

Referring to Figure 11, the process test step according to the present invention is carried out in the step of load input-information collection before the test-change the configuration information-test execution-information collection after the test-load blocking and testing as in the scenario as shown in FIG. Changes, validations, test runs, and information gathering steps may be repeated for different sub-item tests.

Process test according to the present invention can be divided into 20 large category test items (Test 01 ~ Test 20), the Nth test item (Test N) of the N-1 step, N-2 step, N-3 step, There may be Nn test, and all tests are carried out in order in order to put the load in each step at the same time and proceed in the same test condition.

Each step again includes Nn.1 setting information and an event execution request-response step (N-1.1, N-2.1, N-3.1 ,, Nn.1) and an Nn.2 information collection request-response step (N−1). 1.2, N-2.2, N-3.2 ,,, Nn.2), and the total time required for Test N is (T1 + T2) × n (n: by test item) when each required time is T1, T2. Number of test steps) + β (time required for other steps such as connection establishment and disconnection). This equation can be expressed as the total time required for Test N = (T1 + T2) × n + β.

At this time, in the setting information and event execution request-response step of Nn.1, T1 (setting information) is a step of checking the electricity meter time change, load setting change, event occurrence time, etc. by controlling the electricity meter or load input unit 130 for each test step. And event execution request-response time) can be within a few tens of seconds, and in the Nn.2 information gathering request-response step, T1 (setting information and configuration information) takes about 10 minutes to read 6,240 LPs in 9600bps serial communication. Event execution request-response time is much shorter than T2 (information gathering request-response time).

In addition, the total time required for the N-th test item (Test N) of the M power meters 110a... 110n is a time obtained by adding only the M process wait times α to the total time required for Test N. The equation may be expressed as Test N total time required for M power meters 110a... 110n = (T1 + T2) × n + β) + α.

If there is no response or normal response in the test step among the M meter tests (110a… 110n), the meter meter (110a… 110n) in question has to perform the process again, so that the test is performed in multiples of T1 + T2 hours. It may take longer. Therefore, in the case of T1, which takes a short time within a few seconds, if it is a failure or a timeout rather than a normal response, it will retry the step before moving on to the next step. By adding only the test time of the test, a more efficient method in terms of time can be saved.

In addition, the N-n.2 information gathering step results only in the state where the setting information change confirmation is normal in the preliminary step N-n.1 setting information and the event execution step. This is because the result value when the setting information is not normal may affect the suitability of the test result. Therefore, when a problem occurs, retry the Nn.1 setting information and the event execution step having a relatively short time, and increase the success rate of the normal response through retransmission, and greatly affect the overall time required in the next step. You may not.

In particular, when a plurality of power meters (110a… 110n) at the same time when the test does not come in response to the next step proceeds to the next step only proceeds to the normal response by retrying only the setting information and the event execution step of Nn.1 It is reliable as a test result when the success rate is increased, and when the Nn.1 setting information and the event execution step are normal and the next Nn.2 information collecting step is performed.

FIG. 12 is a diagram for describing a scenario to which a method of operating a process for parallel meter processing is applied based on recording table information configured as shown in FIGS. 9 and 10.

Referring to FIG. 11, the present invention is roughly classified into about 20 test items for each function in order to perform a process test, and each test item is classified into 10 stages on average. For example, the history recorder function of power meter includes power failure, recovery, time change, demand power recovery, manual demand power recovery, program change, current limit and current limit release, remote load switching, sag generation and swell generation.
