Description

Street lamp controller upgrading method and network bridge node
Technical Field
The invention belongs to the field of software upgrading, and particularly relates to a street lamp controller upgrading method.
Background
The narrowband Internet of Things (NB-IoT) becomes an important branch of the world-wide Internet. The NB-IoT is constructed in a cellular network, only consumes about 180kHz bandwidth, and can be directly deployed in a GSM network, a UMTS network or an LTE network so as to reduce the deployment cost and realize smooth upgrading.
NB-IoT is an emerging technology in the IoT domain that supports cellular data connectivity for low power devices over wide area networks, also known as Low Power Wide Area Networks (LPWANs). NB-IoT supports efficient connectivity for devices with long standby time and high requirements for network connectivity. It is said that NB-IoT device battery life can be improved by at least 10 years while still providing very comprehensive indoor cellular data connection coverage.
NB-IoT brings great convenience to the intelligent street lamp. 1. The installation and debugging link is simplified, the installation and debugging difficulty for the networking function is greatly reduced, and ordinary street lamp installers can finish the operation without participation of professional engineers. 2. The network stability is enhanced, and each lamp control node has an independent uplink channel which is superior to that of the original scheme that only the gateway node has uplink capacity.
But NB-IoT networks are inherently slow in concurrency and currently the limitations of large operators on the capacity of NB-IoT base stations can result in lower rates on average for a single device. In the street lamp controller based on the NB-IoT technology, since the end software of the controller needs to be upgraded in the problems of change of functional requirements, repair of software Bug, and the like, a problem of how to remotely upgrade the end software of the lamp by the SOTA of the street lamp system based on the NB-IoT technology arises.
Currently, operator platforms of various large NB-IoT communication networks provide an SOTA upgrading scheme, and due to the fact that bandwidth limitation of the NB-IoT networks is considered to avoid influencing service communication of other devices of the same base station in the upgrading process, the SOTA upgrading scheme can limit the number of concurrent upgrading of the same base station, so that NB-IoT streetlamps under the same base station need to be upgraded sequentially, and the upgrading speed of the whole network is low.
How to improve the SOTA upgrading speed of the whole network in the upgrading scheme based on the restriction of the concurrence of the NB-IoT uplink and downlink networks. On one hand, the method adopts a differential package upgrading method for slightly larger software to achieve the purpose of increasing the speed of upgrading the software package each time. However, the differential packet approach has drawbacks: 1. the requirement of the difference algorithm is high, or the upgrade package is not obviously reduced; 2. and each two different versions need to be made into a differential packet, and the management and the upgrading management of the differential packet become very complicated when the versions are multiple.
Disclosure of Invention
The invention aims to solve the problems of low SOTA remote upgrading rate and long upgrading period in the prior art, and provides a novel street lamp controller upgrading method and a network bridge node.
The technical scheme of the invention is as follows: a street lamp controller upgrading method comprises the steps that a base station receives upgrading information sent by a management service platform; the base station selects a bridge node; the base station sends the upgrading information to the selected network bridge node; the network bridge node analyzes the upgrade information and upgrades the node of the network bridge node, and simultaneously forwards the upgrade information to other nodes around through the local network.
Further, the bridge node is a bidirectional double-stranded node.
Further, the base station sends a message whether the node is a bidirectional double-chain node to a certain equipment node connected with the base station; after receiving the message of whether the node is a bidirectional double-chain node or not, the equipment node confirms whether the equipment node has local communication capacity or not, and if the node is the bidirectional double-chain node, the equipment node sends the message of the bidirectional double-chain node to the base station; if the mobile terminal is not provided with the local communication capability and is not the bidirectional double-chain node, sending a message of the bidirectional double-chain node to the base station.
Further, if the base station receives the bidirectional double-chain message sent by the equipment node, the equipment node can be determined to be the bridge node; if the base station receives a message which is not a bidirectional double-chain node or does not receive a message which is a bidirectional double-chain node, the bridge node is reselected.
Further, the local network may include a WIFI network, a zigbee network, or a PLC network.
Further, the bridge node may forward the upgrade information in a broadcast or multicast manner.
The second technical scheme of the invention is as follows: a bridge node comprises an NB communication module, a processor, a memory and a local communication module, wherein the processor is respectively connected with the NB communication module, the memory and the local communication module; the NB communication module is configured to receive the upgrade data information sent by the base station and forward the upgrade data information to the processor; the processor is configured to analyze the upgrade data information, store the information in the memory and upgrade the equipment section of the processor; meanwhile, the upgrading data information is sent to the local communication module; the local communication module is configured to forward the upgrade data information to other nodes using a local network.
Further, the NB communication module is configured to receive a message sent by a base station whether the node is a bidirectional double-chain node; and forwarding the message whether the node is a bidirectional double-chain node to the processor; the processor is configured to reply the message of whether the node is the bidirectional double-chain node to the NB communication module, and the NB communication module sends the message to the base station.
Further, the local network may include a WIFI network, a zigbee network, or a PLC network.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings. 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.
The invention will be further described with reference to the accompanying drawings.
Example one
Fig. 1 is a schematic diagram of an equipment node control system applied to an intelligent street lamp according to an embodiment of the present invention.
As shown in fig. 1, the device node control system includes a management service platform 1, a base station 2 (including base stations 2A,2B,2C), and a device node 3 (including device nodes 3A-3E). A plurality of base stations 2, such as a base station 2A, a base station 2B, a base station 2C, etc., are disposed under one management service platform 1, and a plurality of device nodes 3A, a device node 3B, a device node 3C, a device node 3D, etc., are disposed under one base station 2. The base station 2 and the device node 3 may be connected through an NB-IoT communication network, the device node 3 may be connected through a local communication network, the local communication network may be a PCL network, a Zigbee network, or a Wifi network, and the like, and the base station 2 and the device node 3 may not be connected, for example, in fig. 1, the base station 2B is connected to the device node 3A, the device node 3B, the device node 3C, and the device node 3D, but the base station 2B is not connected to the device node 3E. The device nodes 3 may not be connected to each other, for example, the device node 3A may only remain NB-connected to the base station 2B and not have a local connection to other device nodes.
Since the communication capabilities of each device node 3 in the communication link are different, the device nodes 3 may be divided into a free node, an NB single-chain node, a local single-chain node, and a bidirectional double-chain node. The device nodes 3 of different communication capabilities are characterized as follows:
name (R) Feature(s)
Free node NB link communication failure, local link communication failure
NB single-chain node Normal NB link communication and failure of local link communication
Local single-chain node NB link communication fails, local link communication is normal
Bidirectional double-chain node NB link communication is normal, local link communication is normal
TABLE 1
The device node 3 can be divided into 4 roles from the perspective of whether or not it can proxy for the local device node 3: bridge nodes, bridge candidate nodes, relay nodes, and common nodes. The specific introduction of the device nodes with different roles is shown in the following table:
Figure BDA0002948241280000041
TABLE 2
As can be seen from table 1 and table 2, the bidirectional double-stranded node may be a bridge node and a bridge candidate node, the relay node may be a local single-stranded node or a bidirectional double-stranded node, and the NB single-stranded node may only perform NB communication with the base station 2 and may not be a bridge node and a relay node. And the free node is in the state of losing connection, the state information of the free node cannot be acquired on the management service platform 1, the management service platform 1 cannot transmit commands and data to the free node, and maintenance personnel are needed for maintaining the free node, so that the free node is connected to the network.
Example two
Fig. 2 is a schematic flowchart of a method for selecting a bridge node by a base station according to an embodiment of the present invention.
As shown in fig. 2, the method for selecting a bridge node by the base station 2 includes the following steps:
s21, the base station 2 sends a message to a certain device node 3 connected thereto whether it is a bidirectional double-chain node;
s22, after receiving the message of whether it is a bidirectional double-chain node, the device node 3 determines whether it has local communication capability, and if so, it is a bidirectional double-chain node (the bidirectional double-chain node can be used as a bridge node), and sends the message of the bidirectional double-chain node to the base station 2; if the local communication capability is not available, the node is not a bidirectional double-chain node, and a message that the node is not a bidirectional double-chain node is sent to the base station 2.
S23, if the base station 2 receives the two-way double-chain message sent by the device node 3, it is determined that the device node 3 can be used as a bridge node to send SOTA upgrade information; if the base station 2 receives a message that is not a bidirectional double-stranded node, or does not receive a message that is a bidirectional double-stranded node, the bridge node is reselected.
When the base station 2 selects a bidirectional double-chain node as a bridge node, the SOTA upgrade can be started.
Fig. 3 is a schematic diagram of a preferred SOTA upgrading method according to an embodiment of the present invention.
As shown in fig. 3, the flow of the SOTA upgrading method is as follows:
s31, the base station 2 receives SOTA upgrade data information sent by the network service platform 1;
s32, the base station 2 sends the received SOTA upgrade data information to the selected bridge node in fig. 2;
s33, the selected bridge node 3 analyzes the SOTA upgrade data information, and forwards the SOTA upgrade data information to other equipment nodes through the local network;
specifically, the selected bridge 3 parses the SOTA upgrade data information, and upgrades the own device section.
The selected bridge node 3 can send the SOTA upgrading data information to other peripheral equipment nodes in a broadcasting or multicasting mode, and the other peripheral equipment nodes upgrade the self equipment nodes after receiving the SOTA upgrading data information and also forward the SOTA upgrading data information. The local network may be a WIFI network, or a PLC network, etc.
Optionally, the SOTA upgrade data information may include a hop count for broadcasting the data information, and if the management service platform 1 sets the hop count for broadcasting the SOTA upgrade data information to 10 hops, the management service platform does not perform broadcasting any more when the data information is broadcasted once minus 1 until the hop count is reduced to 0.
The SOTA upgrading method uses the NB-IOT network less, can improve the upgrading speed, and avoids the long-time fault of the equipment node caused by too long time consumption in the network upgrading process.
Fig. 4 is a schematic structural diagram of a device node as a bridge node according to an embodiment of the present invention.
As shown in fig. 4, the device node as a bridge node (may be simply referred to as a bridge device node) includes an NB communication module 41, a processor 42, a memory 43, and a local communication module 44. The processor 42 is electrically connected to the NB communication module 41, the memory 43, and the local communication module 44, respectively.
The NB communication module 41 is configured to receive a message sent by the base station 2 whether the message is a bidirectional double-chain node; and forwards the message of whether it is a bidirectional double-stranded node to the processor 42;
and a processor 42 configured to reply the message of whether the node is a bidirectional two-way double-chain node to the NB communication module 41, and the message is sent to the base station 2 by the NB communication module 41.
The NB communication module 41 is further configured to receive the SOTA upgrade data information sent by the base station 2 and forward the SOTA upgrade data information to the processor 42.
And the processor 42 is configured to analyze the SOTA upgrading data information, store the SOTA upgrading data information in the memory 43 and upgrade the equipment section of the processor. Meanwhile, the SOTA upgrade data information is sent to the local communication module 44, and the local communication module 44 sends the SOTA upgrade data information out by broadcasting or multicasting using the local network.
Optionally, the SOTA upgrade data information may include a hop count for broadcasting the data information, and if the management service platform 1 sets the hop count for broadcasting the SOTA upgrade data information to 10 hops, the management service platform does not perform broadcasting any more when the data information is broadcasted once minus 1 until the hop count is reduced to 0.
In the invention, the multiple embodiments all adopt a mode of NB communication network + local communication network, so that the problem of poor parallel transmission capability caused by the simple use of NB communication network in the prior art is solved, the parallel transmission efficiency is improved, and the perception of users is greatly improved.
