Embodiment Construction

[0047] The invention provides a method for realizing the real-time performance of a broadband bus in the field layer of the industrial Internet, which is suitable for a two-wire data transmission network. In the embodiment of the present invention, by determining the number of devices on the bus, time slices are allocated to devices on each bus, so that each bus device can operate within the time slices it occupies, and the time slices of different bus devices That is to say, through the embodiment of the present invention, only one device at most performs data operations on the bus in different time slices, avoiding collision and blockage of transmission data on the bus, and ensuring the real-time performance of data transmission.

[0048] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodime...

Abstract

The invention discloses an industrial Internet field layer broadband bus real-time performance realization method. The method comprises steps: a bus controller determines the number of bus terminals connected with the bus controller, the bus controller distributes a time slice for each bus terminal according to the number of bus terminals, the time slice is sent to the bus terminal, and thus, the bus terminal operates in the distribution time; and in addition, in the case of data transmission in a bus system, through removing Ethernet/IP message header information, the message length is shortened, transmission delay is reduced, a bus scanning period is shortened, and the real-time performance of the bus system is further improved. Through the embodiment of the invention, at most one device performs data operation on the bus in different time slices, the message length is shortened, transmission data collision and blockage on the bus are avoided, and the data transmission real-time performance is ensured.

Description

technical field [0001] The invention relates to the technical field of information processing, in particular to a method for realizing the real-time performance of a field layer broadband bus of the industrial Internet. Background technique [0002] With the development of Internet technology, various buses are widely used in industrial field automation to realize real-time monitoring of the industrial field by the control terminal, and according to different application fields, the requirements for data transmission rates are also different, especially for servos and robots. For systems with high precision requirements, the timely transmission of field data and control data directly affects the performance of the system, and there is still a bottleneck in the real-time performance of the current bus. [0003] The real-time performance of the existing Ethernet data transmission is poor. Since the Ethernet adopts the CSMA / CD collision detection method, when the network load i...
