The accompanying drawings are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate the invention and together with the embodiments of the invention, serve to explain the invention. In the drawings:
fig. 1 is a schematic diagram of a module structure of the present invention.
Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the invention; all other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The novel networking control system based on Zigbee provided in this embodiment, as shown in fig. 1, includes:
a Zigbee node: the Zigbee nodes may be various types of internet of things devices such as sensors, actuators, or controllers. Each Zigbee node has a unique identification number, called a short address, for identification and addressing in the Zigbee network. The nodes communicate with neighboring nodes via wireless channels and transmit data by establishing a network topology. Zigbee nodes typically consist of a microcontroller, wireless transceiver and associated sensors or actuators. The microcontroller is responsible for processing the computing and control tasks of the node, and the wireless transceiver is responsible for wireless communication with other nodes. The nodes may send and receive data packets over the wireless channel, which may contain sensor readings, actuator instructions, or network management information. In a unified network architecture system, zigbee nodes implement connections with ethernet devices by communicating with Zigbee gateways or other Zigbee nodes. The node may send a data packet to the Zigbee gateway, and then the gateway forwards the data packet to the ethernet device, or may directly perform point-to-point communication with other Zigbee nodes. Zigbee nodes typically have low power consumption characteristics and can be battery powered and run for long periods of time.
Second, zigbee gateway: the main function is to connect the Zigbee network and the Ethernet, and realize data exchange and communication between the Zigbee network and the Ethernet. In a unified network architecture system, a Zigbee gateway plays an important bridge role. It is not only a Zigbee node, which can communicate with other Zigbee devices, but also a gateway, which can forward data in the Zigbee network to the ethernet, and transmit data from the ethernet to the devices in the Zigbee network. Zigbee gateways typically have an ethernet interface and a wireless transceiver. The ethernet interface is used to connect to ethernet devices, and generally uses an ethernet protocol for data transmission. The wireless transceiver is configured to wirelessly communicate with Zigbee nodes and is capable of receiving and transmitting Zigbee data packets in an appropriate frequency band (e.g., 2.4GHz, 900MHz, or 868 MHz). Key functions of the Zigbee gateway include data forwarding, network management, and security guarantee. It receives the data packet from the Zigbee node and forwards it to the corresponding target device or other Zigbee node according to the target address. At the same time, it is also responsible for processing the data packets from the ethernet device and delivering them to the appropriate Zigbee device. The data forwarding function enables the Zigbee network and the Ethernet to communicate with each other, and integration and interoperation of a unified network architecture system are achieved.
Third, ethernet device: ethernet devices are various devices connected to ethernet in a unified network architecture system, such as PCs, servers, routers, etc. Ethernet is widely used in various fields as a general network protocol. By connecting to the ethernet, these devices can communicate and exchange data with devices in the Zigbee network. Ethernet devices use Ethernet protocols for data transmission and are typically connected to a local area network or the internet using a standard Ethernet interface, such as an Ethernet interface. They may communicate with the Zigbee gateway via ethernet to enable connection to the Zigbee network. The ethernet device may send a data packet to the Zigbee gateway and then forward the data by the gateway to devices in the Zigbee network or directly communicate point-to-point with the Zigbee node. Ethernet devices play an important role in unified network architecture systems. They can exchange and communicate data with other ethernet devices through ethernet interfaces, and at the same time connect with devices in the Zigbee network through Zigbee gateways. In this way, the ethernet device may interact with various Zigbee devices through the Zigbee network, so as to implement integration and interoperation of the application of the internet of things. Ethernet devices in a unified network architecture system may have a variety of functions and applications. For example, the PC can exchange data with various sensor devices through a Zigbee network to realize environment monitoring and data acquisition; the server can communicate with a large number of control devices through a Zigbee network, so that intelligent home or industrial automation control is realized; the router can be used as a relay node in the network and is responsible for forwarding data packets, managing network topology and the like.
Fourth, network protocol conversion module: which is responsible for converting Zigbee protocols and ethernet protocols. Because Zigbee and ethernet use different communication protocols, a network protocol conversion module is required to implement data format conversion and exchange between the two. One of the main functions of the module is to encapsulate a data packet of the Zigbee protocol into a data packet of the ethernet protocol or parse the data packet of the ethernet protocol into data of the Zigbee protocol. In the data encapsulation process, the network protocol conversion module converts and encapsulates the payload and control information of the Zigbee data packet so as to enable the payload and control information to conform to the format and specification of the Ethernet protocol. Similarly, in the data parsing process, it parses the ethernet packet into a data structure of the Zigbee protocol, so as to facilitate processing and identification of the Zigbee device. The network protocol conversion module may also handle address mapping and conversion between different network protocols. For example, it may map the short address of the Zigbee device to the IP address of the ethernet device or map the IP address of the ethernet device to the short address of the Zigbee device. This address mapping and translation mechanism allows for proper addressing and communication between Zigbee devices and ethernet devices.
Fifthly, a network management module: the network management module is responsible for managing aspects of network configuration, device discovery, security and the like of the whole system. The system provides monitoring, control and management capability for the whole network, and ensures the normal operation and safety of the network. The network management module can monitor the state of the Zigbee network, including node connection, topology structure update, network expansion and the like. It can identify the newly added Zigbee node and assign it a short address and network parameters. Through the joining and leaving operations of the nodes, the network management module can dynamically adjust the network topology structure and maintain the stability and reliability of the network. The network management module is also responsible for management of network configuration. It may provide a user interface or command line tool for setting network parameters, adjusting communication frequency and power, etc. Such configuration management functions allow users to customize the network as needed to meet specific application requirements. In a unified network architecture system, the network management module also handles security issues. It can provide the functions of identity verification, data encryption, secure communication, etc. to protect confidentiality and integrity of communication data. Through the encryption algorithm and key management mechanism, the network management module can ensure that only authorized devices can access the system and protect the data from unauthorized access and tampering.
Sixth, the security encryption module: the security encryption module ensures confidentiality and integrity of communication data in the transmission process by using an encryption algorithm and a key management mechanism. One of the main functions of the secure encryption module is data encryption. It encrypts the data to be transmitted using one or more encryption algorithms, making it unreadable to unauthorized visitors during transmission. Common encryption algorithms include symmetric encryption and asymmetric encryption. Symmetric encryption uses the same key to encrypt and decrypt data, while asymmetric encryption uses a pair of keys, one for encryption and the other for decryption. The secure encryption module is responsible for generating, storing and managing these keys and performing encryption and decryption operations during data transmission using the appropriate keys. In addition to data encryption, the secure encryption module is also responsible for integrity verification of data and tamper resistance. By using techniques such as hash functions or message authentication codes, the secure encryption module may generate a digital signature of the data for verifying whether the data was tampered with during transmission. The receiving end can verify the validity of the digital signature by using the corresponding key so as to ensure the integrity of the data. In addition, the security encryption module can also provide an identity verification function. It can be used to verify the identity of the device and to ensure that only authorized devices can access the system. The secure encryption module may enable authentication between devices and establish a secure communication link using techniques such as key exchange protocols and digital certificates.
It is noted that relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
