Embodiment

[0021] as attached figure 1 As shown, the hardware connection diagram of the IoT system. Microcontroller STM32F407 is the core processor, which is connected to the Ethernet interface RJ45 through the Ethernet physical layer transceiver DP83848, so as to realize the signal transmission or reception with the external industrial Ethernet.

[0022] The microcontroller is connected to the sending or receiving of external signals through the serial port, including sending and receiving of human-computer interaction information, and sending of time information.

[0023] The Ethernet physical layer transceiver DP83848 carries on the underlying network communication. The Ethernet interface is used for TCP / IP communication to complete the receiving and sending of data in the network. The serial port is used to receive user-configured parameters and output current system information for system monitoring and debugging.

[0024] Analyze the synchronization accuracy by observing the out...

Abstract

The invention relates to the technical field of network communication apparatuses, and discloses an Internet of Things system. A microcontroller STM32F407 is used as a hardware system core, an Ethernet physical layer transceiver DP83848 is used for performing underlying network communication, and a peripheral interface is responsible for sending or receiving external signals and comprises an Ethernet interface and a serial port. The accurate time synchronization of the IEEE1588 protocol is realized, the synchronization process can be divided into two stages: offset measurement and delay measurement, and the Internet of Things system is suitable for all kinds of application occasions of distributed industrial networks.

Description

technical field [0001] The present invention relates to the technical field of network communication devices, and more particularly relates to an Internet of Things system. Background technique [0002] The Internet of Things is an important part of the new generation of information technology, and the Internet of Things is the Internet where things are connected. This has two meanings: first, the core and foundation of the Internet of Things is still the Internet, which is an extended and expanded network based on the Internet; Exchange and communication, that is, things are closely related. The Internet of Things is an extension of the Internet, including the Internet and all resources on the Internet. Connect sensors, controllers, machines, people and things together in new ways to form a network that connects people and things, things and things, and realizes informatization, remote management control and intelligence. [0003] For the existing network environment, in...
