The invention will be further explained with reference to the drawings.
Example one

As shown in fig. 1, the device node control system includes a management service platform 1, a base station 2, and a device node 3. 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 maintain an NB connection with the base station 2B and may not have a local connection with 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:
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.

As shown in fig. 2, the method for the management service platform 1 to send data information to the device node 3 includes the following steps:
s21, the device node 3 receives the data information sent by the network service platform 1;
specifically, the network service platform 1 first sends the data information to the base station 2, and the base station 2 sends the data information to the device node 3 through the NB network. The data information includes data information related to the device node 3 and data information related to other device nodes around the device node 3.
S22, the equipment node analyzes and analyzes the data information and extracts the data information related to the equipment node;
specifically, the device node 3 parses the data information related to itself from the data information, stores the data information in a memory in the device node 3, and subsequently performs related operations according to the content in the data information, for example, performs a light turning operation at a certain time point or performs a light dimming operation.
S23, the device node 3 judges whether it has local communication ability, if it has local communication ability, it sends data information relative to other device nodes through local network; if not, sending a message that the local communication capability of the network service platform is not available to the network service platform;
if the device node 3 has local communication capability, the device node 3 belongs to a bidirectional double-chain node and can be used as a bridge node. The device node 3 may send data information to other peripheral device nodes in a broadcast or multicast manner, for example, the data information may include IDs of multiple device nodes and data information corresponding to the IDs, and after receiving the data information, a certain device node compares whether its ID matches the ID in the data information, if so, extracts data information related to itself, and if not, sends the data information to other peripheral device nodes, and at this time, the device node serves as a relay node.
Optionally, the data information may include a hop count for broadcasting the data information, for example, the management service platform 1 sets the hop count for broadcasting the data information to be 5 hops, and the data information is broadcasted every time minus 1 until minus 0, and then the data information is not broadcasted any more.
EXAMPLE III
Fig. 3 is a schematic diagram illustrating a method for uploading information to a management service platform by a device node according to an embodiment of the present invention.
As shown in fig. 3, the method for uploading information to the management service platform 1 by the device node 3 includes the following steps:
s31, device node 3 broadcasts the message of searching for bridge node to the peripheral device nodes;
specifically, since the device node 3 has not sent a message to it through a bridge node before, nor sent a message to it by a bridge node, the device node needs to find a device node that can serve as a bridge when it sends a message to the management service platform 1 for the first time.
S32, the device node 3 capable of acting as a bridge broadcasts a message confirming itself as a bridge node, at which point the bridge node determines.
S33, device node 3 sends its own device information to the bridge node.
And S34, the bridge node sends the equipment node information to the management service platform 1 according to the service strategy.
Specifically, the service policy includes that the bridge node collects information of the peripheral device nodes 3 periodically and forwards the information to the management service platform 1, for example, the bridge node collects information of a plurality of device nodes 3 within 5 minutes, and packages and sends the information to the management service platform 1 when the information arrives within 5 minutes.
S35, the service management platform 1 processes the device node information sent by the bridge node.
The device node information may be state information of the device node, such as voltage current condition, water inlet condition, temperature condition, lamp on-off state, and the like.

The data information is, for example, on/off time setting information, dimming setting information, and the like of the street lamp.
When the device node 3 needs to upload data to the management service platform 1, the local communication module 44 is configured to receive a bridge node finding message sent by another device node, and send the bridge node finding message to the processor 42.
The processor 42 is configured to generate an acknowledgement as a bridge node message based on the find bridge node message and send the acknowledgement as a bridge node message to the local communication module 44 for broadcast or multicast by the local communication module 44 over the local network.
The local communication module 44 is further configured to receive the own device information sent by the other device node, and send the own device information to the processor 42. The processor 42 is configured to transmit the device node information to the management service platform 1 through the NB communication module 41 according to the traffic policy.
The sending of the device node information to the management service platform 1 through the NB communication module 41 according to the service policy includes integrating the device node information sent by one or more other device nodes through local communication within a predetermined time, sending the integrated device node information to the NB communication module 41, and sending the integrated device node information to the management service platform 1 through the NB communication module 41.
