[0001] The present invention relates to the technical field of electric meter devices, and in particular, to a method, a system, an electronic device, and a storage medium for quickly identifying a newly added electric meter. Background Art

[0002] In practical applications, in order to automatically handle the situation of adding an electric energy meter under a collector, it is necessary to regularly detect whether a new electric energy meter number is added under the collector. In fact, the situation of adding an electric energy meter is less.

[0003] The invention patent with the publication number CN118631786A discloses a method for quickly searching for a rail-mounted electric energy meter, including the following steps: S1: The rail-mounted electric energy meter issues a wildcard address AAAAAAAAAAAA through the 485 channel to start the meter search process; S2: Analyze the feedback on the 485 bus; S3: Process the result analyzed in S2; S4: For the illegal message in S3, refine the processing through a new round of wildcard address AAAAAAAAAAAX; S5: According to the analysis result of the wildcard address AAAAAAAAAAYX, continue to use the processing method in S4, and gradually solve the address conflict by shrinking the position by one bit forward, and perform up to 12 searches to confirm the specific address; this method has a cumbersome detection process, still requires a long time in the case of no newly added electric energy meter, has low efficiency, and does not consider the situation of few newly added electric meters.

[0004] Therefore, providing a method for quickly identifying a newly added electric meter with high efficiency is an urgent problem to be solved at present. Summary of the Invention

[0031] Figure 1 is a flowchart of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] In view of the above problems, the present invention provides a method, system, electronic device and storage medium for quickly identifying newly added electricity meters; the present invention first silences the existing electricity meters through a silent instruction, so that they do not reply to the subsequent adapter address instructions, and only the newly added electricity meters will reply. Since the interference of the existing electricity meters is excluded, the time for detecting new meter numbers is shortened. The collector of the present invention judges whether there are newly added electricity meters and the number of newly added electricity meters by judging whether the data frame is correct, and selects corresponding operations according to specific situations. The first preset time of the present invention can be adjusted and selected according to actual needs, with high flexibility. The present invention sends a full AA adapter address instruction, and the electricity meters that meet the conditions will make a reply.

[0034] Embodiment 1

[0035] As Figure 1 shown, a method for quickly identifying newly added electricity meters, the method is used to control the communication between the collector and the electricity meters, and the method specifically includes:

[0036] S1. The collector sends a silent command to the electricity meter, and the electricity meter that receives the silent command does not reply to the AA adapter address command within the first preset time.

[0037] S2. The collector sends a full AA adapter address command to the electricity meter, and the newly added electricity meter sends a data frame to the collector after receiving the full AA adapter address command.

[0038] S3. If the collector does not receive a data frame, it indicates that there is no newly added electricity meter, and the search ends.

[0039] S4. If the collector receives a data frame, it indicates that only one newly added electricity meter exists. The collector stores its data frame and ends the search.

[0040] S5. If the collector receives garbled characters, it indicates that multiple newly added electricity meters exist, and a normal electricity meter number search operation is started.

[0041] The data frame includes address data.

[0042] The specific normal electricity meter number search operation includes:

[0043] S51. The collector uses the full AA adapter address command with the lowest byte to read the address from the electricity meter in sequence.

[0044] S52. If a correct data frame is received, store its address and continue the next read.

[0045] S53. If no data frame is received, continue the next read.

[0046] S54. If garbled characters are received, perform reduced-address addressing.

[0047] The lowest byte is in BCD code from 00 to 99, and the remaining bytes are AA.

[0048] The collector sends a silent command to all the electricity meters whose addresses have been collected.

[0049] The first preset time is selected as the longest meter search period.

[0050] The first preset time is 300 s.

[0051] In this embodiment, the specific detection steps are as follows:

[0052] 1. The collector performs an operation on the electricity meter through a unicast command, and the electricity meter that receives the operation does not reply to the adapter address command within a period of time (the length of the time can be fixed, such as 300 s (the longest meter search period can be selected)).

[0053] 2. The collector performs the operation in step 1 on all the electricity meters that have been collected.

[0054] 3. The collector collects the downlink electricity meter address data through the full AA adapter. If not, it indicates that there is no new meter number and the meter search ends. If a correct data frame is received, it indicates that a new electricity meter has been installed, stores its meter address, and ends the meter search. If garbled characters are received (multiple electricity meters send data through the RS485 line simultaneously), it indicates that multiple new electricity meters have been added, and the normal meter number search operation is started.

[0055] In the DL / T 645 protocol and the DL / T 698.45 protocol, when the address is all AA, all nodes with this address reply. If some of the address data bytes match and the rest are AA, the electricity meter also replies.

[0056] In this solution, since the existing electricity meters are made not to reply to the adapter command through a command, the interference of the existing electricity meters is excluded when using the adapter to search for meters. If there are no newly added electricity meters, or if only one new electricity meter is added, the collection of the newly added meter numbers can be completed through one adapter reading. In the current existing meter search solutions, because it is necessary to avoid the replies of the meters that have already been searched, multi-round table searching with reduced addressing is required. In the case of no newly added electricity meters or only one newly added electricity meter, such an operation can greatly improve the efficiency of automatically finding meters.

[0057] The normal meter number search steps are as follows:

[0058] 1. Successively use adapters with the lowest byte being BCD codes from 00 to 99 and the rest being AA to read the electricity address

[0059] 2. If a correct response frame is received, store its address and continue with the next reading. (For example, if a correct response frame is read using AAAAAAAAAAAA23, record the address, and then read the address using AAAAAAAAAAAA24)

[0060] 3. If no response frame is received, continue with the next reading.

[0061] 4. If garbled characters are received, perform reduced addressing. (For example, if a garbled frame is read using AAAAAAAAAAAA23, then successively read the addresses using AAAAAAAA0023, AAAAAAAA0123, AAAAAAAA0223 to AAAAAAAA9923).
