Figure 2 is a flow chart of the off-line power meter inspection and repair operation in the method of power meter communication abnormality detection and notification of the present invention, and is described with reference to Figure 1. At the same time, for the convenience of explanation, the abnormal electricity meter notification unit 323, the abnormal electricity meter management unit 324, the network connection monitoring management unit 325, and the system management terminal 61 shown in Figure 2 are all drawn into two or more, but in fact there is only one or At least one (see Figure 1).

As shown in Figure 2, the meter data capture unit 312 of the southbound system interface module 31 captures a preset time period (such as the previous day or the previous day from 6 a.m. to 6 p.m. The storage unit 313 of the southbound system interface module 31 stores the electric meter data of the multiple electric meter 10 in the storage unit 313 of the southbound system interface module 31. Next, the meter data analysis unit 321 of the core module 32 of the head-end system analyzes the meter data of the plurality of meters 10 captured by the meter data acquisition unit 312 of the southbound system interface module 31, based on the analysis of the meter data As a result, the abnormal electric meters in the plural electric meters 10 and the cause of the abnormality are determined. When the meter data analysis unit 321 finds or determines that the abnormality of the abnormal meter is caused by offline, it will perform the offline meter repair operation or process shown in Figure 2 and follow the offline A1 of the group meter (such as the offline of a large number of or regional meters) With the judgment result of offline A2 of individual meter (such as offline of single, small amount or distributed meter), the following two procedures of inspection and repair work are carried out respectively.

Group meter offline A1 (such as mass or regional meter offline): Obtain, monitor, or determine whether the network connection status of the group meter (or regional meter) is normal or offline through the network connection monitoring and management unit 325. Picture program S11)?

If the network connection status of the group meter is normal, for example, the network connection status shows Start or Alive, the network connection monitoring management unit 325 passes through the head end system core module of the head terminal system 30 32 Obtain or determine whether the electricity meter data of the group electricity meter is to be updated (see procedure S12 in Figure 2)?

If the electricity meter data of the group electricity meter is version updated, the network connection monitoring and management unit 325 confirms or judges whether the group electricity meter is currently connected (see procedure S13 in Figure 2)? If the connection has been restored, the network connection monitoring management unit 325 will reply the offline reason to the abnormal meter management unit 323 as a record or evidence (see the procedure S14 in FIG. 2).

If "the data of the group electricity meter is not version updated" or "the group electricity meter is version updated and the connection has not been restored yet", the network connection monitoring and management unit 325 automatically detects and analyzes the offline reason of the abnormal electricity meter that may be caused, for example The system slows down, the database (DB) has too much data, the hard disk (HD) storage capacity is insufficient, the automatic deletion of the previous meter data setting mechanism is not good, and other offline reasons, and the results of automatic detection and analysis will be passed to the abnormal meter The notification unit 323 notifies the system management terminal 61 (such as the system administrator) by means of short message or application (APP), so that the system management terminal 61 (such as the system administrator) performs system inspection and repair and evaluation of the group electricity meter (abnormal electricity meter). Network connection and communication health indicators, and the repair results are returned to the abnormal meter management unit 324 as a record or evidence (see procedure S15 in Figure 2). Therefore, the network connection monitoring and management unit 325 can analyze the network connection and communication quality of the group electricity meter for the offline A1 of the group electricity meter, so as to establish the network connection and communication quality of the group electricity meter based on the analysis result of the network connection and communication quality.

In addition, if the network connection status of the group electricity meter is offline or abnormal (see procedure S11 in Figure 2), for example, the network connection status shows stop (Stop), the abnormal electricity meter notification unit 323 will send a message or an application (APP ) And other methods to notify the network communication inspection and repair unit 63, so that the network communication inspection and repair unit 63 can perform a wired network (such as a PLC meter module) or a wireless network (such as a RF, NB-IoT meter module) ) Communication quality inspection and repair operations, and the inspection results are returned to the abnormal meter management unit 324 through the application program (APP) as a record or evidence (see procedure S16 in Figure 2).

Individual meter offline A2: Obtain, monitor or determine whether the individual meter's network connection status is normal or offline via the network connection monitoring management unit 325 (see procedure S17 in Figure 2)?

If the network connection status of the individual electricity meter is normal, the electricity meter data analysis unit 321 obtains or determines whether the keep alive (KeepAlive; KA) status of the electricity meter data analysis result of the individual electricity meter is non-maintained alive or maintained alive (see section 2). Picture program S18)?

If the alive state of the individual meter is non-sustainable (KA), the abnormal meter notification unit 323 will notify the communication module inspection unit 62 through a short message or an application program (APP) to perform on-site meter inspection and repair operations (see Section 2). Figure program S19).

If the individual power meter maintains alive status (KA), the abnormal power meter management unit 324 records the log data during the abnormal period of the power meter as evidence (see procedure S20 in Figure 2), and then through the abnormal power meter The notification unit 323 notifies the system management terminal 61 (such as the system administrator) through the wired or wireless network 20 to perform remote or online inspection and repair of the individual meter, so as to confirm or judge whether the individual meter is based on the results of the remote or online inspection Return to normal meter reading (see section 2 Picture program S21)? If the system management terminal 61 returns to normal meter reading after the remote or online inspection and repair, the system management terminal 61 responds to the abnormal meter management unit 324 as a record or evidence (see procedure S22 in Figure 2). Conversely, if the individual meter does not resume normal meter reading after the system management terminal 61 is checked and repaired remotely or online, the system management terminal 61 will reply to the abnormal meter notification unit 323 by means of SMS or application program (APP) to notify the communication module to check The repair unit 62 performs on-site meter inspection and repair operations (see procedure S19 in Figure 2).

In addition, if the network connection status of the individual electric meter is offline or abnormal (see procedure S17 in Figure 2), the abnormal electric meter notification unit 323 will notify the network communication inspection and repair unit 63 through a short message or an application program (APP), etc. Use the network communication inspection and repair unit 63 to inspect and repair the communication quality of the wired network (such as used in PLC meter modules) or wireless network (such as used in RF, NB-IoT meter modules), and will check The repair result is returned to the abnormal meter management unit 324 through the application program (APP) or text message, etc., as a record or evidence (see procedure S16 in Figure 2).

Figure 3 is a flow chart of the on-site power meter inspection and repair work of the power meter on the user side in the method for detecting and reporting an abnormality in the power meter communication of the present invention, and is described with reference to Figure 1. As shown in Figure 3, the power meter 10 on the user side includes the meter body and the communication module (such as RF, PLC, NB-IoT...). When the abnormal power meter notification unit 323 of the head-end system core module 32 is notified to check When repairing unit 60 (such as on-site inspection and repair unit), report and on-site inspection and repair operations are carried out respectively according to the abnormal attributes of the meter body and the communication module.

Abnormality of the meter body: The power company or meter unit 50 (such as the meter body unit) is notified via the abnormal meter notification unit 323 through the wired or wireless network 20. The power company or meter unit 50 (such as the meter body unit) can be sent through SMS or application Program (APP) and other methods to receive the information of the abnormal electric meter from the abnormal electric meter notification unit 323, and judge based on the information of the abnormal electric meter. Whether it is necessary to send personnel to the site to check and repair the meter. If there is no need to send someone to the site for repairs (such as natural disasters, regular maintenance and replacement of meters... etc.), the power company or meter unit 50 (such as the meter body unit) can reply to the abnormal meter management unit 324 through the application (APP) For record or evidence. Conversely, if someone needs to be sent to the site for repairs, the power company or meter unit 50 (such as the meter body unit) can notify the repair personnel to go to the site to perform the meter repair work through a text message or an application program (APP) (see the procedure in Figure 3) S31), and reply to the abnormal electricity meter management unit 324 through the application (APP) or text message to record or keep the inspection and repair results (such as abnormal phenomenon, repair status, photo storage certificate...).
