In other words, a slave device among multiple slave devices can have the functions of a master device (primary master or secondary master). In a residential complex cluster containing more than one residential complex, it is reasonable to install a master device connected to the server device in the power company facility (1) via a communication line in each of the residential co-complexes to send the meter data of each residential unit to the electricity company.

In other words, secondary masters (12) and tertiary masters (13) can be connected via wireless communication via a multi-stage protocol that allows relaying to the primary master (11) through another secondary master and does not allow relaying through any slave device. . RF slave devices installed in homes, i.e. first RF slave device (24-1), second RF slave device (24-2), third RF slave device (24-3), fourth RF slave device (24-4), fifth RF slave device (24-5), the sixth RF slave device (24-6), the seventh RF slave device (24-7), the eighth RF slave device (24-8), the ninth RF slave device (24-9) is usually used in surrounding buildings, cars and their installation in low positions easily affected by obstacles such as trucks makes their stability sensitive for wireless communication. On the other hand, secondary masters (12) and tertiary masters (13) are composed of PLC slave devices, i.e. third PLC slave device (22-1), fourth PLC slave, sixth PLC slave device (and RF slave devices (24-3 to 24-24). 9) since you send meter data to the primary host (II) wirelessly, the quality of communication between the secondary masters (12) and the third] masters (13) and the primary master (1 1) is greatly affected by the performance capability of the remote metering. masters (12) and tertiary masters (13) can select another secondary master or primary master (II) as a higher node only, and RF slave devices, that is, the first RF slave device (24-1), the second RF slave device (24-2), third RF slave device (24-3), fourth RF slave device (24-4), fifth RF slave device (24-5), sixth RF slave device (24-6), seventh RF slave device (24-7), eighth RF slave device (24-8), ninth RF slave device (24-9) may not select.

Thus, a stable wireless communication path is established, as the secondary masters (12) and tertiary masters (13) are connected only to the primary master (11) via multi-stage wireless communication, which includes only the secondary masters (12) and tertiary masters (13). can be created and measurement errors can be reduced. The format of a hello packet sent wirelessly in the communication system shown in Figure 1 is shown in the following Table-l: Message High Reservation Node Array Uplink Link Link Type speed complete type number node information failure mode information request response information flag Secondary master devices ( 12) and tertiary hosts (13) periodically or randomly place information, such as a hello packet, on a wirelessly sent signal for routing purposes, indicating that the source node of the signal is the secondary master. Table-? The hello packet in is used for routing (creation of paths) in a traditional communication system using multi-stage wireless communication. The hello packet in Table-1 contains multiple fields, including information about, for example, message type, high-speed mode flag, node type, sequence number, uplink information, link information request, link information response, and link break information. The Message type field contains information indicating the packet type (hello packet). The high-speed flag field contains l-bit information indicating whether the packet sending mode is high-speed or low-speed m1. The high-speed flag field contains l-bit information indicating whether the packet sending mode is high-speed or low-speed. The sequence number field contains a number that uniquely identifies the package. The uplink information field contains information about a uplink (ie, a node in the multi-stage sending path from the sending packet origin node to the primary host 11) relative to the packet sending source. The link information request field contains information requesting send progress quality information about a node adjacent to the receiving node. The link information response field contains progress quality information about the neighboring node in the response to the link information request for a hello packet received from another node. Link breaking information contains information about nodes that cannot communicate, for example, due to poor feed quality. While sending the hello packet shown in Table-P, secondary masters (12) and tertiary hosts (13) write the information indicating that they are master devices in the node type field and, according to the secondary master, write the information about a parent node in the `info field', Secondary hosts The hello packet sent by (12) and tertiary host (13) contains uplink information, but when there is no uplink relative to the primary host (1 l), the topnode information field in the hello packet sent by the primary host (11) is blank. Thus, the primary master (ll), secondary masters (12) and tertiary masters (13), and RF slave devices using a pre-existing hello packet format, i.e. the first RF slave device (24-1) and the second RF slave device ( 24-2), third RF slave device (24-3), fourth RF slave device (24- 4), fifth RF slave device (24-5), sixth RF slave device (24-6), seventh RF slave device ( 24-7), it is possible to distinguish between the eighth RF slave device (24-8), the ninth RF slave device (24-9). Using the hello packet shown in Table-F, the secondary masters (12) and tertiary masters (13) are separated from the primary master (1 l), secondary masters (12) and tertiary masters (13) and RF slaves, i.e. primary RF slave device (24-1), second RF slave device (24-2), third RF slave device (24-3), fourth RF slave device (24-4), fifth RF slave device (24-5), sixth RF slave device slave device (24-6), seventh RF slave device (24-7), eighth RF slave device (24-8), ninth RF slave device (24-9) can determine which is a neighbor node and only have one secondary as a parent node can select the main host or the primary host. By sending and receiving the hello packet sent in Table-F. pre-existing devices performing multi-stage wireless communication, while secondary masters (12) and tertiary masters (13) are connected to the primary master (11) by multi-stage wireless communication, which only includes secondary masters (12) and tertiary masters (l3). ensures compatibility with a communication system. It should be noted that the signal sent periodically or randomly over the wireless for routing purposes is described as a hello packet, without limiting it; another packet can be used for routing purposes.

The second] masters (12) and the third] masters (13) are connected to the primary master (11) only a group of PLC slave devices, that is, the third PLC slave device (, the fifth PLC slave device (, the Nth PLC slave device (23-N) ) sends counter data wirelessly. This reduces the work load and sending traffic of the second] masters (12) and the third] masters (l3), which means the PLC slave devices, i.e. the third PLC slave device (22-1), the fourth PLC slave device ( allows establishing a stable communication path between the sixth PLC slave device and reducing measurement errors.

Second] masters (12, 13) each along the path to the primary master (11) one or more secondary masters (12) and tertiary masters (13) and/or one or more RF slaves, i.e. primary RF slave device (24-1), second RF slave device (24-2), third RF slave device (24-3), fourth RF slave device (24-4), fifth RF slave device (24-5), sixth RF slave The device (24-6) is connected via multi-level wireless communication, which includes the seventh RF slave device (24-7), the eighth RF slave device (24-8), the ninth RF slave device (24-9). In general, when constructing a path from a slave device to a master device, the total value of the link costs (reception quality) for all links along the slave-to-master path is calculated as the path cost, and the path with the lowest path cost is selected. For example, secondary masters (12) and tertiary masters (13) are RF slaves, i.e. first RF slave (24-1), second RF slave (24-2), third RF slave (24-3), fourth RF slave device (24-4), fifth RF slave device (24-5), sixth RF slave device (24-6), seventh RF slave device (24-7), eighth RF slave device (24-8), ninth In order to increase the bus cost of a bus containing RF slave device (24-9), it is recommended that RF slave devices, i.e. first RF slave device (24-1), second RF slave device (24-2), third RF slave device (24-3), fourth RF slave device (24-4), fifth RF slave device (24-5), sixth RF slave device (24-6), seventh RF slave device (24-7), eighth RF slave device (24-8), ninth The RF slave device (24-9) can create a path by applying a price to the path cost (reception quality). With this, path selectively leads to RF slave devices i.e. first RF slave device (24-1), second RF slave device (24-2), third RF slave device (24-3), fourth RF slave device (24-4). , fifth RF slave device (24-5), sixth RF slave device (24-6), seventh RF slave device (24-7), eighth RF slave device (24-8), ninth RF slave device (24-9) preferably includes secondary hosts (12) and tertiary hosts (13). Since the secondary masters (12) and tertiary masters (13) are connected to the primary master (1 l) via multi-stage wireless communication, preferably using the secondary masters (12) and tertiary masters (l3), a stable wireless communication path can be established and measurement errors can be reduced. In addition, when there is at least one RF slave device with a suitable path for wireless propagation between any two devices within the primary master (11) and the secondary masters (12) and the tertiary masters (13), that includes the RF slave device. a path can be created. This makes it possible to create a stable communication path and to reduce measurement errors.

This is b It makes it possible to simplify the structure of the primary host (ll). In addition, in the second collection method, the number of PLC slave devices managed by the primary master 11 is less than in the first collection method, which means that the number of RF slave devices participating in the communication system can be increased by an equal number of differences. According to the communications system shown in Figure 1, the secondary masters 12 and tertiary masters 13 act as multi-level powerline communication coordinators (concentrators) in the settlement complexes 32, 33 and also relay in multi-stage wireless communications. act as slave devices (pseudo slave devices) that perform functions. Therefore, the communication system shown in Figure 1 can control and efficiently use wireless resources as a single wireless system, for example, avoiding wireless signal interference. This makes it possible to provide a communication system that can communicate efficiently with dependent devices provided in various environments such as a residential complex or a home. EDIT 2 First] master (11) primary master (11), secondary masters (12) and tertiary masters (13), PLC slave devices ie first PLC slave device (21-1), second PLC slave device (, fourth PLC slave device (, fifth PLC slave device ( and RF slave devices i.e. first RF slave device (24-1) second RF slave device (24-2), third RF slave device (24-3), fourth RF slave device) device (24-4), fifth RF slave device (24-5), sixth RF slave device (24-6), seventh RF slave device (24-7), eighth RF slave device (24-8), ninth RF slave Creates and manages network configuration information for a network containing devices (24-9). (11) and includes multi-level communication path information between each slave device, etc. Network configuration information is a component in the operation of the primary master. It takes time and effort to regenerate the network configuration information to rebuild the network if it is lost due to a glitch or primary host failure. Therefore, to temporarily stop the primary host or replace the primary host, it is necessary to shut down the communication system for an extended period of time. Embodiment 2 provides a communications system that can easily regenerate a primary host network even when the primary host's operation is interrupted or fails. Figure 7 is a sequential diagram illustrating the backup of network configuration information according to Arrangement 2 of the present invention. The primary host (11) creates a backup ID as the credential for the primary host (11). This backup ID is part of the network configuration information. The primary master 11 periodically wirelessly sends a backup signal containing network configuration information (including redundant ID) to at least one of the secondary masters 12 and tertiary masters 13. Network configuration information may include a timestamp indicating when the backup signal was sent. When receiving the backup signal wirelessly, the secondary hosts 12 and tertiary hosts 13 store network configuration information in nonvolatile memory 53. When an administrator replaces the primary host (11) with a new primary host (i.e., a different primary host) due to a primary host failure, the backup ID is replaced by a maintenance terminal (not shown in the figures) that can communicate with the primary host (1 l) is entered. the substitution primary master 11 sends an information signal containing the spare 1D to the secondary masters I2 and tertiary masters 13. When wirelessly receiving the acknowledgment signal, the secondary masters 12 and the third] masters 13 wirelessly send a reply signal to the replacement primary master II. The substitute primary master 11 wirelessly sends a request signal requesting network configuration information to at least one secondary master 12, which is the transmit source node of the response signal. The secondary master (12) compares the backup 1D in the backup signal with the backup 1D in the information signal. If the redundant 1Ds match, the secondary master 12 wirelessly sends a restore signal to the replacement primary master 11 containing network configuration information stored in nonvolatile memory 53. If the backup 1Ds match, the secondary master 12 wirelessly sends the restore signal even if the sending source of the information signal and the original primary master which has recovered from the request signal failure, or the replacement primary master 11. According to the procedures shown in Figure 7, if the faulty state on the primary host is corrected or a faulty primary host is replaced with a new primary host, the time required to rebuild the network can be shortened by making a backup of the network configuration information from the secondary host. Since the secondary master stores the network configuration information in non-volatile memory, the network configuration information is saved even if the secondary master is powered off. The first] master device (11) may divide the network configuration information into multiple parts. The size of each piece can be at most a length that can be sent over the network in a single transmission. The primary master (ll) allocates administrative identification numbers (page numbers) to parts. The first] master (1 l) periodically wirelessly sends multiple signals, each containing one of the parts and one of the identification numbers, to at least one of the secondary masters 12 and tertiary masters 13. This wireless transmission is carried out, for example, during a period during which the sending of the hello packet and the sending of the counter data request signal by the primary host 11 can be performed. When multiple signals containing parts and credentials are received, secondary hosts (12) and tertiary hosts (13) combine parts according to their identification numbers to form network configuration information and store network configuration information in nonvolatile memory (53). In this way, the primary host 11 can back up the network configuration information while maintaining the telemetry performance without interrupting the sending of the hello packet and the meter data request signal. The substitute primary master 11 may wirelessly send the information signal and the request signal to the secondary masters 12 and tertiary masters 13 at predetermined times. While the new primary host is being set up, for example, when the new primary host is set up late at night, even when the administrator is not in the area, the administrator can pre-set the time to send the notification signal and demand signal on the primary host. In this way, the replacement primary host 11 can automatically retrieve backed up network configuration information from the secondary hosts 12 and the third] hosts 13. The first] host device (ll) can create a network credential. First] master (1 1), second] masters (12) and third] masters (13), PLC slave devices, i.e. first PLC slave device (, third PLC slave device (, Mth PLC slave device (22- M), fifth PLC slave device (23-1), sixth PLC slave device (23- 2), Nth PLC slave device (23-N) and RF slave devices, i.e. first RF slave device (24-1), second RF slave device (24-2), third RF slave device (24- 3), the fourth RF slave device (24- 4), the fifth RF slave device (24- 5), the sixth RF slave device (24- 6), the seventh RF slave device (24- 7), the eighth RF slave device (24- 8), the ninth RF slave device (24- 9) communicate with each other using network credentials. The second] hosts (12) and the third] hosts (13) store the network credential in nonvolatile memory (53). The second] masters 12 and the third] masters 13 receive the notification signal and the reply signal wirelessly from the substitute first] master 11 . Here, if the spare 1Ds match, the secondary masters 12 and the third] masters 13 wirelessly send the network configuration information stored in nonvolatile memory 53 to the replacement first] master 11 without using the network credential. The first] master 11 may back up multiple copies of the same network configuration information (or part) to more than one secondary master 12, 13. Additionally, when the amount of free space in non-volatile memory 53 on the second] hosts (12, 13) is low, the primary host 11 may divide the network configuration information into parts and save the different parts in more than one second] host (12, 13). Figure 8 is a sequential diagram illustrating the backup of network configuration information according to a variation of Arrangement 2 in the present invention. Before receiving the backup signal wirelessly, the primary host 11 splits the network configuration information. In addition, the replacement primary master 11 wirelessly sends a request signal to all secondary masters 12 and third] masters 13 that store partitioned network configuration information, and from these second] masters (12) and third] masters (13) wirelessly receives a restore signal. Substitute first] restores the master device (11) network configuration information. The communication system according to Regulation 2 provides a communication system that can easily regenerate a primary host network and resume operation in a short time, even when the operation of the primary host is interrupted or fails. Above, the communication system according to the present invention is explained according to the regulations, but the communication system is not limited to the regulations. Arrangements consisting of arbitrary combinations of structural elements in arrangements and variations thereof, as well as various modifications in arrangements which are understandable to those skilled in the art, are considered within the scope of the present invention as long as the essence of the present invention is not deviated. the third] can be implemented as hardware in the main devices (13) and as a program run by their control circuits. In addition, the First PLC slave device (21-l) shown in Figure 4 and the RF slave device shown in Figure 5, the first RF slave device (24-1), show configurations where the watt-hour counter is integrated into other circuits, but the watt-hour counter is integrated into other circuits. -The clock counter and other circuits can also be supplied as separate modules. In this case, the slave device receives its meter data from the residential watt-hour meters. In addition, in the communications system according to Regulations 1 and 2, the slave devices are not limited to watt-hour meters and may be other meters, such as gas or water meters that can operate using at least one communications protocol, including powerline communications and wireless communications. In addition, the communication system according to Arrangement 1 or Z can be configured from multiple communication devices different from management devices for meters and communication devices.
