As shown in fig. 2, an embodiment of the present invention provides an electricity consumption information acquisition system based on broadband carrier and bluetooth communication, including a master station, a concentrator, and a plurality of meter boxes, where a plurality of meter modules are disposed in the meter boxes, and a plurality of first bluetooth modules and a relay module are further disposed in the meter boxes; the first Bluetooth module and the relay module are respectively connected with an ammeter module in a plug connector mode, and the relay module comprises a broadband carrier module and a second Bluetooth module connected with the broadband carrier module through an SPI (serial peripheral interface); a Bluetooth 5.0Mesh network is formed between a first Bluetooth module and a second Bluetooth module in a meter box, and the first Bluetooth module is used for sending the electricity utilization information of each electricity meter module to the relay module through the Bluetooth 5.0Mesh network; the second bluetooth module is used for passing through bluetooth 5.0Mesh network acquire with the power consumption information of each ammeter module that first bluetooth module connects, and send to broadband carrier module, broadband carrier module is used for passing through the power line transmission to the table case outside with the power consumption information of all ammeter modules in the table case through broadband carrier communication mode.
Fig. 3 is a schematic structural diagram of a bluetooth 5.0Mesh network in a meter box according to an embodiment of the present invention; in the embodiment of the invention, the electric meter meets the national grid standard Q/GDW1355-2013, the external interface of the first Bluetooth module is adapted to the electric meter interface, and is physically connected with the electric meter in a connector assembly mode to form a Bluetooth 5.0 acquisition node of the electric information acquisition electric meter terminal. Dozens of Bluetooth 5.0 acquisition nodes are arranged in the meter box, and a Bluetooth 5.0Mesh network is constructed between the nodes. The network transmits the electricity utilization information of each electricity meter node to the relay module.
In this embodiment, the external interface of the relay module is adapted to the interface of the electric meter module, and is physically connected to one of the electric meter modules in the form of a connector, so as to form a relay node of the power consumption information acquisition electric meter terminal. The relay module comprises a second Bluetooth module and a broadband carrier module. The second Bluetooth module realizes communication with a Bluetooth 5.0Mesh network, acquires power utilization information of each node, and transmits the received power utilization information to the broadband carrier module through the SPI bus. The broadband carrier module transmits the electricity utilization information to the outside of the meter box through a power line, and a communication network between the meter boxes based on the broadband carrier communication technology is formed between the meter boxes.
In the embodiment of the invention, aiming at the practical application characteristics of the Bluetooth node in the meter box, the route construction of the Bluetooth 5.0Mesh network is completed by adopting a flooding routing algorithm. The flooding routing algorithm is a simple and efficient routing algorithm, and the basic principle is that a received data message is sent to other nodes on a path until the message is received by a target node. The routing algorithm has the characteristics of good network robustness and high fault tolerance, but easily causes a large amount of data packets and occupies limited resources. In order to solve the problem of low data transmission efficiency caused by a large number of packets possibly generated in the network, in this embodiment, the initial value of the TTL value in the bluetooth 5.0Mesh network is set to 3, and a packet sequence number (SEQ) is maintained to perform duplicate packet detection, and the received packets are discarded. The node processing message flow chart is shown in fig. 4, and the route construction process is as follows: and the node receives the data packet and judges whether the data packet is a target node, if so, the data packet is processed, if not, the TTL value is judged whether to be larger than zero, if not, the data packet is discarded, if so, whether the data packet is a repeated data packet is judged according to the data packet sequence number, if so, the data packet is discarded, and if not, the TTL value is reduced by 1, and the data packet is forwarded.
Further, as shown in fig. 5, a schematic structural diagram of a wideband carrier networking between meter boxes in the embodiment of the present invention is shown; in the embodiment of the invention, the external interface of the relay module is adapted to the interface of the ammeter module, and is physically connected with the ammeter in the form of a connector, so that a conversion node of a Bluetooth communication technology and a carrier communication technology between meter boxes is formed. The relay module is communicated with the Bluetooth acquisition node in the meter box through a Bluetooth 5.0Mesh network, is communicated with the relay modules in other meter boxes through broadband carrier communication to construct a network based on a broadband carrier communication technology, and uploads the power utilization information acquisition to a remote master station through communication interaction with a concentrator.
Specifically, in this embodiment, the meter boxes communicate with each other through a broadband carrier, and the topology structure adopts a tree topology. The inter-meter box module communication has the characteristics of large node number, relatively sparse arrangement and concentrator-side information acquisition source nodes, in the embodiment, a dynamic source routing algorithm (DSR for short) is adopted between meter boxes to plan a path from a source node to a target node, and an improved method is adopted to improve the robustness and the efficiency of the DSR algorithm.
The DSR algorithm is characterized in that a routing mechanism of a source node is used, the header of a data packet of the source node carries a path from the source node to a target node, and only when the data packet initiated by the source node does not contain a complete path reaching the target node, route discovery needs to be initiated to find a route reaching the target node. In order to realize a routing mechanism, each node needs a cache region for storing routing information, the routing algorithm does not need to periodically update the routing information, the intermediate node does not need to store the routing information of the forwarding data packet, the network overhead is low, and the occupation of a channel is reduced.
In the broadband carrier communication of this embodiment, when a data packet sent by a source Node does not include a complete path, the source Node initiates a route discovery request packet RREQ, carries a destination Node address and a sequence number of a unique identifier, and places the source Node address at the head of a Node List. The intermediate Node judges whether to continue forwarding and adds the address into the Node List until finding the route reaching the target Node, and replies a route response packet RREP. Specifically, the route discovery process is as shown in fig. 6, and the broadband carrier networking process between the plurality of relay nodes and the concentrator includes the following steps:
s1, a source Node initiates a routing request packet, the routing request packet carries a destination Node address and a serial number of a unique identifier, and the source Node address is placed at the head of a Node List;
s2, the intermediate node judges whether the node is a target node, if yes, a routing response packet is replied; if not, go to step S3;
s3, judging whether the route to the target node is contained, if yes, replying a route response packet, and if not, entering the step S4;
s4, judging whether the data packet is a repeated data packet, if not, entering the step S5; if yes, judging whether the address is added into the Node List, if so, discarding the data packet, and if not, entering the step S5;
and S5, adding the Node address into the Node List and then forwarding.
Further, in this embodiment, in the broadband carrier networking process, when it is detected that a node is not accessible through the route maintenance mechanism, the upper node and the lower node at the failure location establish a new route by initiating list operation. When a message is transmitted in a complete route, the DSR algorithm detects connectivity between the node and the next node through a route maintenance mechanism. When a traditional DSR algorithm finds that a node is not communicated, a routing error packet RERR is sent to a source node, the source node carries out communication or initiates routing discovery to search a complete path according to other routing information of a buffer area of the source node, and the problem that the communication delay is large, a channel is occupied and the like is caused by the mode that the node is not communicated, so that the DSR algorithm is not suitable for being applied to a system with high real-time requirement. In this embodiment, an improved idea is adopted to optimize the DSR algorithm for the case of node communication failure, and a basic idea is that when a routing maintenance mechanism detects that a node is obstructed, upper and lower nodes at a failure location establish a new route by initiating list operation, so as to quickly recover a complete route. As shown in fig. 7, in this embodiment, a complete path for communication between a source node a and a target node E is a-B-C-D-E, and when a route maintenance mechanism detects that a communication fault occurs at a node C, nodes B and D that hop up and down to the node C are located. Path planning is done by establishing a new route between nodes B and D. Taking fig. 7 as an example, two new paths, namely a-B-G-D-E and a-B-F-G-D-E, can be planned, and a new complete route is finally selected as a-B-G-D-E according to the principle of fewer hops.
For the condition that the arrangement among meter boxes is relatively sparse and the number of network nodes is large in the electricity utilization information acquisition system, the improved DSR algorithm adopted by the embodiment of the invention can be better suitable for practical application, and the efficiency and the real-time performance of the electricity utilization information acquisition system are improved.
Further, as shown in fig. 8, in this embodiment, the first bluetooth module includes an interface circuit, a power supply circuit, a bluetooth communication module and an antenna, the bluetooth communication module passes through the interface circuit is connected with the ammeter module, the power supply circuit is used for getting points from the ammeter module, and supplies power to the bluetooth communication chip after converting 12V dc voltage into 3.3V, the bluetooth communication module passes through the antenna sends out bluetooth signal, and communicates with the bluetooth module in the ammeter case and organizes the network.
Fig. 9 is a schematic circuit diagram of the interface circuit in this embodiment. In the embodiment, the interface circuit is used for realizing physical connection and electrical information interaction with the electricity meter end, and meets the standard Q/GDW 1355-2013. The electric meter can adapt to electric meters of different manufacturers, and has the characteristics of strong universality and low cost. As shown in fig. 10, which is a schematic circuit diagram of the power supply circuit in this embodiment, the power supply circuit obtains power from the electric meter module, and realizes that 12V changes into 3.3V, and supplies power to the bluetooth chip, and the power supply chip in the selected power supply circuit has high conversion efficiency, and reduces power consumption. As shown in fig. 11, it is a schematic circuit diagram of the bluetooth communication module in this embodiment, wherein the model of the main chip of the bluetooth communication module is nRF 52840. In this embodiment, the bluetooth communication module converts the information interacted with the electric meter module into a bluetooth signal, radiates to the air interface through the antenna, and performs communication networking with other bluetooth 5.0 nodes in the meter box.

In this embodiment, simulation and actual test optimization are performed in combination with the electric meter structure, and the antenna can achieve higher gain to achieve radiation efficiency.
Specifically, in this embodiment, the relay module further includes an EMC protection circuit, as shown in fig. 13, where the EMC protection circuit is disposed on an SPI interface between the second bluetooth module and the broadband carrier communication module.
