Industry internet field broadband bus architecture system
First Claim
1. An industry internet field broadband bus architecture system, wherein the system comprises a bus controller and at least one bus terminal, and the bus controller is connected with the respective bus terminals over a two-wire data transmission network, wherein:
- the bus controller is synchronized in clock with the respective bus terminals;
allocates time slices for the bus controller and the respective bus terminals; and
transmits first data to be transmitted, in their respective time slices;
the bus terminals are configured to transmit second data to be transmitted, in their respective time slices;
wherein the bus controller is further configured to acquire the data, and then determine whether the data are real-time data or non-real-time data; and
if the data are real-time data, to store the real-time data into a first real-time data container;
otherwise, to store the non-real-time data into a first non-real-time data container;
the bus terminals are further configured to acquire the data, and then determine whether the data are real-time data or non-real-time data; and
if the data are real-time data, to store the real-time data into a second real-time data container;
if the data are non-real-time data, to store the non-real-time data into a second non-real-time data container;
wherein the bus controller is configured to determine whether the bus controller operates in the time slice thereof, and if the bus controller operates in the time slice thereof, to retrieve the real-time data from the first real-time data container in the time slice as the first data to be transmitted, and to transmit the first data; and
if the real-time data container is empty, to retrieve the data from the first non-real-time data controller as the first data, and to transmit the first data; and
the bus terminals are configured to determine whether the bus terminals operate in their respective time slices, and if the bus terminals operate in their respective time slices, to retrieve the real-time data from the second real-time data container in the time slices as the second data to be transmitted, and to transmit the second data; and
if the real-time data container is empty, to retrieve the data from the second non-real-time data controller as the second data, and to transmit the second data.

Abstract
The invention relates to an industry internet field broadband bus architecture system based on the two-wire data transmission network widely used in the traditional industry control system, so that the system can provide high-performance Ethernet communication without modifying original wiring and topologies, thus providing a high-performance, highly reliable, highly real-time, and highly secured solution to switching an industry control system field layer network from a traditional field bus to an industry Ethernet bus.
