Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An embodiment of the present invention provides an intelligent electric meter management system, an example of a system architecture of which is shown in fig. 1, and the system architecture includes: the system comprises a server 10, an information transmission device 20 and a plurality of intelligent electric meters 30, wherein the intelligent electric meters 30 form a wireless grid network.
The information transmission apparatus 20 is wirelessly connected with the server 10, and at least one of the plurality of smart meters 30 is wirelessly connected with the information transmission apparatus 20.
The following is a brief introduction to a wireless mesh network:
a wireless mesh network, i.e., a wireless mesh network, in which any wireless device node can simultaneously act as an access point and a router, send and receive signals, and communicate directly with one or more peer nodes.
In this embodiment, the information transmission device 20 may be a gateway or a router. In addition, an ethernet module is preset in the server 10, an ethernet module and a zigbee wireless module are preset in the information transmission device 20, and a zigbee wireless module is preset in each smart meter 30. The information transmission apparatus 20 communicates with the server 10 through an ethernet network and communicates with the smart meter 30 through a zigbee wireless network. The smart meters 30 communicate with each other through the zigbee wireless network.
And the server 10 is used for acquiring a control instruction aiming at the target smart electric meter and sending the control instruction to the information transmission equipment 20.
In this embodiment, the control instruction includes, but is not limited to, one or more of a meter reading instruction and a configuration instruction, where the meter reading instruction is used to read meter data, such as total power consumption, and the like, and the configuration instruction is used to configure meter parameters, such as relay state (trip state and closing state), rated power, rated total power consumption, and the like.
And the information transmission device 20 is used for determining an electric meter routing path for transmitting the control instruction to the target intelligent electric meter and sending the control instruction to the target intelligent electric meter according to the electric meter routing path.
In this embodiment, the information transmission device 20 may determine the electric meter routing path by using an igbee routing algorithm. The zigbee routing algorithm can be any one of a Cluster-Tree algorithm, an AODVjr algorithm and a routing algorithm (ZBR) combining the Cluster-Tree and the AODVjr. It is understood that the foregoing is only an example of the igbee routing algorithm, and other non-enumerated algorithms are also within the scope of the present embodiment.
For convenience of understanding, the three zigbee routing algorithms are briefly described as follows:
Cluster-Tree algorithm: the forwarding of the packet data is always forwarded to an upper parent node or a lower child node along a tree structure, for example, the address is A; the routing node with depth D receives the packet data with destination address D, firstly judges whether the routing node is the destination node, and if yes, sends a multiframe back to the upper layer; if not, judging whether the destination node is a child node of the destination node according to the following formula, namely: ar < D < Ar + Cskip (D-1), if the destination node is a child node of the routing node, the packet data is forwarded to the corresponding child routing node or child terminal node, if not, the packet data is forwarded to a parent node Cluster-Tree algorithm of the packet data, which is suitable for occasions with fewer mobile nodes and belongs to static routing. The algorithm has the advantages that the forwarding judgment condition is simple, and a routing table does not need to be stored, so that the routing overhead of a single node is low; the disadvantage is that the packet data forwarding path is not optimal, and the routing node closer to the coordinating node has larger forwarding load, and the energy consumption of the whole network node is uneven. In the tree routing algorithm of the zigbee network, nodes do not need to find a route, and only need to forward data according to the parent-child relationship, so that network loops and control routing overhead can be avoided. However, there are disadvantages that the nodes can only communicate along the tree structure, and when a certain trunk is congested, the nodes can only wait or give up transmission, thereby causing delay and packet loss of data transmission; in addition, the trunk with a large load has a large data traffic, and the trunk with a light load is in an idle state for a long time, so that imbalance of energy consumption is caused, and the life cycle of the network is reduced.
AODVjr algorithm: the method aims at the improvement of an AODV (Ad hoc on-demand distance vector routing protocol) algorithm, and the basic principle is that the route searching and recording are realized by flooding route request packets RREQ, and the optimal path is selected by utilizing the response of a target node to the first arriving RREQ packet. Only the destination node can send the RREP packet, and the problems of invalid RREP packet occurrence and circulation can be avoided. Considering factors such as energy conservation and application convenience, the method simplifies some characteristics of the AODV, but still maintains the original function of the AODV, has the advantage of optimal routing path, and has the disadvantages that a routing searching mode of AODVjr flooding needs a large amount of routing overhead, network congestion is possibly caused, nodes with low protection residual energy are not provided, and the overall routing cost is high. Since the purpose of the AODVjr algorithm is only to pursue the shortest path and ignore other problems. The path with the minimum hop count may have poor signals, the path with the minimum hop count may be very congested, a large amount of energy is consumed for finding the path with the minimum hop count, the path with the minimum hop count is concentrated on a node close to the middle, and the like, and meanwhile, when the route is found by using the AODVjr routing algorithm, the RREQ is forwarded when the number of the RREQ is more than 3 hops, unnecessary loss of energy is caused, and the RREQ has no direction selection, and a broadcast storm is easily caused.
Cluster-Tree + AODVjr Combined routing Algorithm (ZBR): the algorithm combines the advantages of two routing algorithms of Cluster-Tree and AODVjr, and subdivides nodes in the network into 4 classes, namely Coordinator, RN +, RN-and RFD; wherein, the Coordinator RN + and the RN-are all full-function nodes, but the two nodes have the functions of route discovery and message forwarding, and start the AODVjr algorithm to actively search the optimal path when forwarding the message; RN-has a route discovery function, starts a Cluster-Tree algorithm when transmitting data, makes a judgment through self computing capacity, and transmits the message to a father node or one of child nodes; RFD is a reduced function device that can only act as a leaf node, i.e. it can only transmit messages to the parent node, please forward them.
For convenience of understanding, the control instruction transmission process is described below by taking three smart meters 30, two of which are smart meters in the meter routing path (hereinafter referred to as smart meter a and smart meter B, respectively), and one of which is a target smart meter as an example:
the electric meter routing path is intelligent electric meter A → intelligent electric meter B → target intelligent electric meter, the information transmission equipment 20 determines the intelligent electric meter A from the plurality of intelligent electric meters 30 wirelessly connected with the information transmission equipment by analyzing the electric meter routing path, and sends the control instruction and the electric meter routing path to the intelligent electric meter A; similarly, the intelligent electric meter A determines an intelligent electric meter B from a plurality of intelligent electric meters 30 wirelessly connected with the intelligent electric meter A by analyzing an electric meter routing path, and sends a control instruction and the electric meter routing path to the intelligent electric meter B; similarly, the smart meter B determines a target smart meter from the plurality of smart meters 30 wirelessly connected to itself by analyzing the meter routing path, and transmits the control command to the target smart meter.
And the target intelligent electric meter is used for responding to the control instruction under the condition that the networking state is the online state, and sending a response result to the information transmission equipment 20 according to the electric meter routing path.
And the target intelligent electric meter can immediately detect the networking state of the target intelligent electric meter when receiving the control instruction, and responds to the control instruction if the networking state is an online state.
Assuming that the electric meter routing path is intelligent electric meter A → intelligent electric meter B → target intelligent electric meter, the target intelligent electric meter determines the intelligent electric meter B from the plurality of intelligent electric meters 30 wirelessly connected with the target intelligent electric meter through analyzing the electric meter routing path, and sends a response result to the intelligent electric meter B; similarly, the intelligent electric meter B determines the intelligent electric meter A from the plurality of intelligent electric meters 30 wirelessly connected with the intelligent electric meter B by analyzing the electric meter routing path, and sends the response result to the intelligent electric meter A; also, the smart meter a transmits the response result to the information transmission apparatus 20 by resolving the meter routing path.
Otherwise, if the networking state is the offline state, the prompting information for representing the offline state may be fed back to the information transmission device 20 according to the electric meter routing path, so as to be uploaded to the remote server 10 through the information transmission device 20, thereby completing the prompting.
Of course, the target smart meter may also re-determine a new meter routing path for transmitting the response result to the remote server 10, and transmit the response result to the information transmission apparatus 20 according to the new meter routing path, thereby adapting to a complicated and diversified network environment.
The information transmission device 20 is also used for sending the response result to the server 10.
In this embodiment, the server 10 may further store the response result in a database for later tracing.
In other embodiments, the server 10 is further configured to:
and outputting a response result under the condition that the control instruction comprises a meter reading instruction.
When the meter reading instruction is triggered by the user through the user terminal, the server 10 may output the response result to the user terminal, so that the user terminal displays the read meter data, such as the total power consumption, the power consumption, and the like, to the user terminal.
In some other embodiments, the target smart meter is further configured to:
and under the condition that the networking state is the offline state, updating and storing the current electric meter information.
In this embodiment, when the target smart electric meter is offline, the current electric meter information may be automatically updated and stored at preset time intervals, for example, every 1 hour. Of course, a storage time period may also be set, such as continuously recording the electricity meter information of the last 1 month. Therefore, the loss caused by the loss of the information of the electric meter due to the fact that the electric meter is disconnected can be reduced.
Further, on the basis of the target smart electric meter being offline, the target smart electric meter is further configured to:
sending a heartbeat signal to the server 10 through the information transmission device 20 according to the electric meter routing path; under the condition of receiving a heartbeat confirmation signal returned by the information transmission equipment 20 according to the electric meter routing path, determining that the networking state is switched from the offline state to the online state; wherein, the heartbeat confirmation signal is returned to the information transmission device 20 by the server 10 after receiving the heartbeat signal.
In this embodiment, when the target smart electric meter is offline, a heartbeat signal is sent according to a certain frequency. If the target intelligent electric meter is recovered to be on-line from off-line, the heartbeat signal can be successfully sent to the information transmission equipment 20 according to the electric meter routing path, the heartbeat signal is forwarded to the server 10 by the information transmission equipment 20, and the server 10 feeds back a corresponding heartbeat confirmation signal based on the heartbeat signal. Therefore, if the target smart meter receives the heartbeat confirmation signal, the target smart meter can be determined to be recovered to be on-line from off-line. To enable networked self-diagnostics.
Further, on the basis that the target smart meter is restored from offline to online, the target smart meter is further configured to:
under the condition that the networking state is switched from the offline state to the online state, sending the current electric meter information to the information transmission equipment 20 according to the electric meter routing path;
the information transmission device 20 is further configured to send the current electricity meter information to the server 10.
In this embodiment, the process of the target smart meter sending the current meter information to the information transmission device 20 may refer to the process of the target smart meter sending the response result to the information transmission device 20, which is not described herein again. The server 10 may update the database upon receiving the current meter information to achieve timely synchronization of the meter information.
Further, on the basis that the target smart meter is restored from offline to online, the target smart meter is further configured to:
under the condition that the networking state is switched from the offline state to the online state, sending a configuration synchronization request to the information transmission equipment 20 according to the electric meter routing path, wherein the configuration synchronization request is used for requesting the latest electric meter parameters;
the information transmission device 20 is also used for sending a configuration synchronization request to the server 10;
the server 10 is further configured to obtain the latest electric meter parameters based on the configuration synchronization request, and send the latest electric meter parameters to the information transmission device 20;
the information transmission equipment 20 is further configured to send the latest electric meter parameters to the target smart electric meter according to the electric meter routing path;
and the target intelligent electric meter is also used for storing the latest electric meter parameters.
In this embodiment, the target smart meter may send a configuration synchronization request to the information transmission device 20 at a designated configuration synchronization time, for example, at 1 minute after the online is recovered, so as to obtain the latest meter parameters of the server 10, such as a new relay state, a new rated power, and a new rated total power consumption.
The process of sending the configuration synchronization request to the information transmission device 20 by the target smart meter may refer to the process of sending the response result to the information transmission device 20 by the target smart meter; similarly, the process of sending the latest electric meter parameter to the target smart electric meter by the information transmission device 20 may refer to the process of sending the control instruction to the target smart electric meter by the information transmission device 20, which is not described herein again. Therefore, the electric meter parameters of the target intelligent electric meter can be updated timely.
Furthermore, on the basis that the target intelligent electric meter obtains the latest electric meter parameters, the electric meter parameters comprise relay states, and the relay states comprise a tripping state and a closing state; and
the target smart meter is further used for:
determining a latest relay state based on the latest electricity meter parameters;
under the condition that the latest relay state is a tripping state and the current relay state is a closing state, controlling a relay of a target intelligent electric meter to execute tripping operation;
and controlling the relay of the target intelligent electric meter to execute the closing operation under the condition that the latest relay state is the closing state and the current relay state is the tripping state.
In this embodiment, the target smart meter may update the current relay state based on the minimum relay state, and if the current relay state and the minimum relay state are the same, the trip/close operation is not performed. Based on the embodiment, the remote management of the intelligent electric meter can be realized, and the intelligent electric meter is applied to a rented room market or a student apartment to realize the functions of remote arrearage tripping, recharging and closing.
In some other embodiments, the target smart meter is further configured to:
under the condition that the networking state is an offline state and the current relay state is a closing state, judging whether the current power utilization information meets a preset tripping condition; and if the current power utilization information meets the preset tripping condition, controlling a relay of the target intelligent electric meter to execute tripping operation.
In this embodiment, the target smart meter may automatically determine whether the current power consumption information needs to be tripped according to the current meter parameter when the target smart meter is offline, for example, the preset tripping condition is that the current total power consumption exceeds the rated total power consumption, and for example, the target smart meter performs a tripping operation when the current power exceeds the rated power. This enables self-management of the smart meter without remote manipulation of the server 10.
In addition, in order to show the topological network of the electric meter management system to the user in time, the server 10 may further output a schematic diagram of the connection between the information transmission device 20 and the smart electric meters 30 and the connection between the smart electric meters 30 to the user side.
