Problems solved by technology

[0005] Generally, there is mostly a single communication method between the gateway device and the remote monitoring device. When the on-site environment changes, another gateway device needs to be replaced, which greatly restricts the use of the gateway device and causes waste of resources.
Moreover, the security of the communication between the node module and the gateway device in the IoT communication system is not high

Abstract

The invention aims at providing an Internet of things (IoT) gateway device with strong compatibility and high integration level and communication security. The IoT gateway device provided by the invention is arranged in a communication network composed of at least one node device connected with a field device, and used for communicating with an external communication device, and is characterized by comprising a central node unit used for communicating with each node device based on a predetermined communication rule, a wired communication unit used for communicating with the external communication device in a wired manner, a wireless communication unit used for communicating with the external communication device in a wireless manner, and a network management unit used for implementing network management on the node device, wherein the predetermined communication rule comprises an automatic network access mechanism, an MESH networking mechanism, a time synchronization mechanism and a frequency hopping mechanism; and the network management comprises distributing a network access private secret key and a communication secret key for the node device.

Description

technical field [0001] The invention belongs to the field of the Internet of Things, and in particular relates to an Internet of Things gateway device with strong compatibility, high integration and high communication security. Background technique [0002] With the rapid development of network technology, the exchange and communication of information has gradually expanded from person to person to thing to thing, thus the concept of the Internet of Things came into being. The Internet of Things is to connect things with the Internet through radio frequency identification, infrared sensors, global positioning systems, laser scanners and other information sensing devices in accordance with unified protocol standards, for information exchange and communication, so as to realize intelligent identification and positioning. , tracking, monitoring and management of a network. [0003] The IoT communication system mainly includes two parts: node modules and gateway devices. Where...
