Background
In a wireless broadband power communication system, a Central node (CCO, also referred to as a Central Coordinator (cmo)) needs to timely sense an on-network status of a sub-node in a communication network so as to facilitate network management, where the nodes or the sub-nodes in the communication network may be divided into a Proxy node, a Proxy site, a Proxy Coordinator (PCO), and a general node or a site station (sta). Heartbeat detection is a mechanism for detecting whether a station is offline, and generally, whether an opposite side is connected can be detected by sending heartbeat data at certain intervals. For heartbeat detection of a low-voltage power line broadband carrier communication system, conventionally, in a networking process, each station can sense own neighbor stations according to received discovery beacons and record the neighbor stations to form a discovery list. And each discovery site sends a discovery list message in a timing period, and the discovery list message is used for the proxy site to judge whether the discovery site is actively online or not. The proxy site sends the site activity information in the locally maintained discovery list to the CCO through a heartbeat detection message with a fixed period so that the CCO can collect the information whether the whole network site is on line or not. In the sending process of the heartbeat detection message, the low-level proxy station triggers the heartbeat detection message of the high-level proxy station to generate a new heartbeat detection message, and finally the CCO can collect the whole network station. However, both the list message and the heartbeat detection message are found to be periodic, and related network maintenance messages are more, occupy more CSMA (Carrier Sense Multiple Access) time slots, and have a greater influence on services such as meter reading.

Example 1
The embodiment of the invention provides a communication method for detecting heartbeat, which can be used for heartbeat sending and detection of a wireless broadband power communication system, and as shown in figure 1, the communication method for detecting the heartbeat comprises the following steps:
determining that a beacon frame sent by a neighbor node in a communication network is received in a timing period, wherein the beacon frame sent by the neighbor node has increased bits, the bits correspond to device identifications of the nodes in the communication network, and the values of the bits include heartbeat detection information corresponding to the device identifications of the nodes recorded by the neighbor node in the communication network;
updating a network state identifier corresponding to a device identifier of a neighbor node in a local neighbor list to be an active online identifier, wherein the neighbor node may be one or more nodes, a bit value may be 0 or 1, heartbeat detection information may include heartbeat bitmap information in which a bit value in an increased bit is 1, a node having a device identifier corresponding to a bit value in 1 may be an active online, and may also include heartbeat bitmap information in which a bit value in an increased bit is 0, a node having a device identifier corresponding to a bit value in 0 may be an offline, the increased bit may be a bit sequence (having an order), and the order may be a time slot order of the device identifier allocated when the node enters a network;
updating the network state identifier of the equipment identifier corresponding to the bit in the beacon frame sent by the neighbor node in the local neighbor list to be an active online identifier, if the beacon frame does not need to send the beacon frame again by the local node, the process can be ended temporarily, wherein, the network status identifiers of the device identifiers in the local neighbor list can be changed into active online identifiers according to the device identifiers corresponding to the bits with the value of 1, the device identifiers corresponding to the bits with the value of 0 can be ignored or considered to be merged with the local neighbor list, that is, the network status identifier with the device identifier in the local neighbor list has been updated to the active online identifier in the current timing period, however, the value of the bit corresponding to the device identifier in the beacon frame may still be 0 or 1, and when the value of the bit is 0, the network state identifier corresponding to the device identifier in the local neighbor list may not be changed to be offline in the current timing cycle;
and generating local heartbeat detection information through the local neighbor list, and executing the sending of the local heartbeat detection information.
In some implementations, a communication network in an embodiment of the present invention may include a central node (CCO) and a communication node, where the communication node may include a proxy node (PCO) and a general node (which may be referred to as a station or a child node or a node, STA), and roles of the two may be assigned by the central node or set by the communication node (for example, the STA may set the PCO); after the communication node performs the association request, if the central node allows to join the communication network, the central node may allocate, according to the available timeslot resources, an Equipment Identifier (i.e., a Terminal Equipment Identifier, TEI) of the communication node, for example, a value of a 1 st bit of a 0 th byte is 1, which indicates that a site where the TEI is 1 is found, and a value of a 0 th bit of the 1 st byte is 1, which indicates that a site where the TEI is 8 is found, and accordingly, when the communication node is considered to be offline, the central node may recycle the TEI and the corresponding timeslot resources; the communication method for detecting the heartbeat here may be that a current communication node (any one of PCOs or STAs) and a neighbor node are performed, the neighbor node may be a communication node adjacent to the current communication node on a communication connection in a communication network, the neighbor node may also be used as the current communication node in some cases, and in some communication networks, a central node may also have a neighbor node, and at this time, the neighbor node may also be a central node.
Nodes (CCO, PCO and STA) in the communication network can be configured, each node can have increased bits, and the communication nodes can also have increased bits; the added bits may be fixed-size bits, or may be expanded following the number of nodes accessing the communication network, and the corresponding node on the bit may add a certain number (N) of bits in the beacon frame according to the sequence of the TEIs allocated when the node ever joins the communication network, for representing the heartbeat detection information of each node in the network, where the ith bit corresponds to a node whose TEI is i, the bit being 0 indicates that the node whose TEI is i is not online, and 1 indicates that the node whose TEI is i is online, N is a positive integer, and i is a positive integer and is less than or equal to N. The bit and the value of the bit in the beacon frame can form heartbeat BITMAP Information (BITMAP), the bit occupied by the heartbeat BITMAP information is approximately equal to the maximum accessible node number of the network, and the heartbeat BITMAP information can be adjusted according to the actual conditions such as the node number of the access communication network.
For the process of counting and sending heartbeat of a child node (or a proxy node), as shown in fig. 2, after the child node accesses the network, a periodic timer for initializing neighbor list information is first started, the neighbor list information mainly stores a flag for identifying whether the neighbor node is valid, and information such as the number of SOF frames (Start of frames, which may be called as Start frames) and beacon frames sent in a timer period, and after the timer expires, the content of the neighbor list (local neighbor list) is initialized to ensure the validity of the child node for the statistics of the neighbor node information, and the neighbor list may include information such as a device identifier of the node, an online identifier corresponding to the device identifier, and the number of SOF frames and beacon frames corresponding to the device identifier.
Specifically, it may be determined that a start frame or a beacon frame of a frame sent by the neighboring node in the communication network is received in the timing period, and the sequence of implementation of the specific determination operation is determined according to a frame sent by the neighboring node in an actual situation, which is not limited herein.
If the sub-node receives the SOF frame from the neighbor node in the network, which indicates that the neighbor node is actively on-line, the neighbor list information stored locally is updated, and the corresponding neighbor table entry flag (network state identifier) is set to be valid, for example, the neighbor table entry flag is updated to be the active on-line (on-line) identifier, so as to indicate that the neighbor node is actively on-line.
If the child node receives the beacon frame from the neighbor node in the network, which indicates that the neighbor node is active online, the neighbor list information stored locally is updated, the corresponding neighbor table entry flag is set to be effective to indicate that the neighbor node is active online, and meanwhile, the number of the received beacon frames is increased by one. The beacon frame count of the neighbor node may be used as one of the basis for reselecting the agent when the agent of the child node changes.
The above process of updating the local neighbor list information according to the SOF frames or beacon frames of the neighbor nodes may be performed in multiple cycles with SOF frames or beacon frames being continuously received.
Then, upon receiving some beacon frames, the beacon frames may also have a predefined time slot allocation, which may inform the communication node receiving the beacon frame that the corresponding beacon frame needs to be sent back within a specified time. For example, the received beacon frame may be a beacon frame (a central beacon or a central beacon) that is sent by a central node and requires a current communication node to send a beacon frame, or may be a beacon frame (a central beacon or a central beacon) that is sent by other nodes in a communication network to the current communication node, and according to beacon allocation information in the received beacon frame, it may be determined whether the beacon frame needs to be sent, and if the current node needs and can send a beacon frame (a proxy beacon or a discovery beacon) at this time, the TEIs of active neighbor nodes in a neighbor list stored locally are merged into a heartbeat BITMAP in a beacon frame received before, as a heartbeat BITMAP of the beacon frame to be sent, and specifically, according to the beacon allocation information in the received beacon frame, it is determined whether the local beacon frame is sent, where the received beacon frame and the local beacon frame both have the bit.
After determining to transmit a local beacon frame, merging the received beacon frame center hop detection information into local beacon frame center hop detection information to be transmitted according to a corresponding relationship between a device identifier corresponding to the active online identifier and the bit in the local neighbor list, more specifically, updating a value of a bit having the corresponding relationship in the received beacon frame to an active online flag value, and meanwhile, according to the received beacon frame center hop detection information (i.e., a corresponding value on each bit and bit), retaining the active online flag value that the bit in the received beacon frame already has, and obtaining a local beacon frame to be transmitted (having merged heartbeat detection information or local heartbeat detection information) according to the current bit and the corresponding value on the bit, and transmits a local beacon frame with the incorporated heartbeat detection information.
For example, as shown in fig. 3, after the neighbor list of the current child node is initialized, the neighbor list is associated with the device identity TEI1-TEI9The corresponding network status identifiers may be all 0 (offline identifier, 1 may represent active online identifier), and after receiving the beacon frame of the neighbor node 1, the corresponding relationship between the bit and the device identifier may be updated and recorded in the neighbor list, at this time, the neighbor list and the device identifier TEI are updated and recorded1-TEI9The corresponding network status identifiers may be respectively 0, 1, 0, 1 in turn, and then the beacon frame of the neighboring node 2 may be received, and the beacon allocation information in the received beacon frame requires the current sub-node to send the beacon frame, so that the current sub-node may updateThe value of the bit, the bit sequence formed by the bit and the bit value of the beacon frame processed by the current child node may be 001010011, and the value (101101110) of the bit corresponding to the device identifier in the received beacon frame is merged with the bit sequence according to the bit or the device identifier, so that the current child node may obtain that the bit sequence of the beacon frame to be transmitted is 101111111, and the bit sequence has merged heartbeat detection information (merged heartbeat tmap); in short, in this embodiment of the present invention, in this timing period, a bit of a beacon frame center-jump BITMAP median value 1 sent by a neighbor node may be merged or updated into local heartbeat BITMAP median values 0 and 1, at this time, a bit of a local heartbeat BITMAP median value 0 is changed to a value of 1, a bit of a local heartbeat BITMAP median value 1 is merged to a value of 1, a bit of a local heartbeat BITMAP median value 1 remains unchanged, a bit of a beacon frame center-jump BITMAP median value 0 sent by a neighbor node may also be merged into a local heartbeat BITMAP, and a bit of a local heartbeat BITMAP median value 0 may not affect a value of each bit in the local heartbeat BITMAP, a bit of a local heartbeat BITMAP median value 1 remains unchanged.
It is to be noted that, before a neighboring node (not serving as a first neighboring node) transmits a beacon frame or a SOF frame, the first neighboring node may receive the beacon frame that was transmitted by a second neighboring node (one or more nodes) adjacent to the first neighboring node, and obtain heartbeat detection information corresponding to each device identifier, that is, a bit value corresponding to a corresponding bit, where a value of a bit in the beacon frame transmitted by the first neighboring node may include not only heartbeat detection information corresponding to the device identifier of the node recorded by the first neighboring node, but also heartbeat detection information corresponding to the device identifier of the node recorded by the second neighboring node, and the beacon frame transmitted by the first neighboring node has merged heartbeat detection information.
The embodiment of the invention also provides a communication method for detecting the heartbeat, which comprises the following steps:
receiving a beacon frame sent by a node in a communication network in the communication method for detecting the heartbeat, and storing heartbeat detection information in the beacon frame;
starting a current timing cycle, executing heartbeat detection of nodes of the communication network, and determining whether nodes corresponding to equipment identification in the heartbeat detection information are active online or not;
and when determining that the node corresponding to the equipment identifier in the heartbeat detection information is not actively online, sending an offline indication message to the node which is not actively online.
For the heart beat statistical processing of the central node, as shown in fig. 4, after the central node is powered on, the locally stored heart beat bitmapp is initialized to be all 0. After receiving the beacon frame of the sub-node in the network, the heartbeat BITMAP in the beacon frame is merged with the heartbeat BITMAP stored locally, and the heartbeat BITMAP is stored locally for heartbeat detection.
For the heartbeat detection processing of the central node, as shown in fig. 5, after the network networking is completed, the central node starts a period timer for timing processing of the heartbeat detection. After the heartbeat detection timer is overtime, the central node judges whether each child node is online according to a heartbeat BITMAP stored locally, the value of a bit i in the BITMAP is 0, the child node with the TEI being i is not online, and the value of the bit i being 1 indicates that the child node with the TEI being i is online. For the child node judged to be offline, if the value of the bit corresponding to the device identifier of the child node in the beacon frame received by each central node does not appear to be 1 after the timing period is ended or the network state identifier corresponding to the device identifier of the child node in the neighbor list stored by the central node is not updated to be an active online identifier, the central node sends an offline indication message to the child node, and if the value of the bit corresponding to the device identifier of the child node in the beacon frame received by each central node appears to be 1 before the timing period is ended or the network state identifier corresponding to the device identifier of the child node in the neighbor list stored by the central node is updated to be an active online identifier, the central node judges that the child node is online. After each heartbeat detection processing period is completed, the central node initializes all heartbeat BITMAP stored locally to be 0.
For performing heartbeat detection on the nodes of the communication network, the central node is used as the communication node, and the network state of the nodes in the communication network is obtained through the beacon frame central hop BITMAP sent by each node in the communication network.
The embodiment of the invention carries heartbeat bitmap information of each node in a beacon frame, a periodic timer for initializing a neighbor list is started after a child node accesses a network, the child node updates the neighbor list information stored locally after receiving an SOF frame or a beacon frame of the neighbor node and is used for heartbeat statistics, the child node updates the heartbeat bitmap in the received beacon frame according to the neighbor list information stored locally before sending the beacon frame and is used as the heartbeat bitmap of the beacon frame to be sent, a central node updates the heartbeat bitmap information stored locally after receiving the beacon frame of the child node in the network so as to be used for heartbeat detection, and the central node performs heartbeat detection processing in a periodic mode. The time length of the timing period of the heartbeat detection of the central node is longer than the time length of the initialization period of the neighbor list of the child node.
The embodiment of the invention reduces the sending of network maintenance messages by carrying the heartbeat bitmap for marking whether each node in the network is on line in the beacon frame, and the collection of the heartbeat detection information does not depend on each node to report the heartbeat detection message specially, thereby reducing the occupation of the CSMA time slot by the non-meter reading service of the system and improving the effective utilization rate of system resources; meanwhile, the central node and the child nodes do not need to store a large amount of heartbeat-related content locally, the processing flow is simple and easy to implement, and the implementation complexity is reduced.
