Problems solved by technology

A blockchain only establishes a distributed data verification and management mechanism for part of the data information, and cannot accept other data formats input from the outside. Therefore, it can be said that the executable scripts built on the blockchain involve closed data. and limitations
Most of the existing embedded operating systems are oriented to the control process, they emphasize the control and scheduling of system resources, but ignore the optimization of the communication process between nodes

Embodiment 1

[0057] Such as Figure 7 Shown is a schematic diagram of block chain data update in an embodiment of the present invention, when at a certain moment (time stamp 4), the node operating system (NDOS) of the target node detects that the information summary 2 of the collection node is updated, and the information summary 2 of the collection node The identity information is device number 5 and IP address 5.

[0058] The collection node extracts the information summary 2, collects the node's identity information device number 5 and IP address 5, forms a time stamp 4 and sends it to the target node.

[0059] After the target node receives the data, the node operating system (NDOS) of the target node first merges the data into the end of the data link list, and records the time stamp 4 of this data update.

[0060] The target node compares the summary information under the updated timestamp 4 with the existing summary information in the data link list of the target node. In this emb...

Embodiment 2

[0063] Such as Figure 8 Shown is a schematic diagram of blockchain data update in another embodiment of the present invention. When the node operating system (NDOS) of the target node detects that the data of multiple communication nodes is updated at the same time (time stamp 4), this implementation In the example, the information summary 5 of the collection node is updated, and the identity information of the collection node is device number 5, IP address 5; the information summary 6 of the collection node is updated, and the identity information of the collection node is device number 6, IP address 6.

[0064] The collection node extracts the information summary 5, the collection node's identity information device number 5 and IP address 5, and at the same time the collection node extracts the information summary 6, collects the node's identity information device number 6 and IP address, forms a time stamp 4 and sends it to the target node.

[0065] After the target node r...

Abstract

The invention provides a node operating system integrated with a lightweight block chain. The node operating system is embedded in the data link layer bottom of a communication protocol stack of each communication node. The node operating system comprises an internal managing unit and the lightweight block chain integrated in the node operating system. Library functions of different network protocol stacks are packaged in the internal managing unit, and a protocol stack interface interacting with the library functions of the network protocol stacks is provided. The block chain data of the lightweight block chain defines a unified data chain list. The data chain list comprises sampling node number, timestamp, information abstract and identity information of sampling node. While the communication nodes are communicated mutually, the lightweight block chain only stores the information abstract and the identity information of the sampling node. The node operating system is capable of providing an improvable and developable open platform to a user, so the whole system has the good expandability.

Description

technical field [0001] The invention relates to the technical field of communication electronics, in particular to a node operating system integrated with a lightweight block chain and a method for updating data. Background technique [0002] Blockchain is an important concept of digital currency. It is a series of data blocks associated with encryption methods. Each data block contains a transaction information, which is used to verify the validity of the information and generate the next block, thus forming a Distributed decentralized network. [0003] All the constituent elements in the Internet of Things, such as device nodes and communication resources, are personalized and privatized, and often only serve a single application. This status quo completely violates the vision of IoT data sharing. The architecture basis of the Internet of Things is the wireless sensor network, which is composed of a large number of sensor nodes and uses communication protocols for data tr...
