Industrial guide rail terminal bus structure

Technical Field

The utility model belongs to the technical field of the bus, concretely relates to industry guide rail terminal bus structure.

Background

Currently, the mainstream form of the computer Control system is dcs (distributed Control system). The fieldbus Control system fcs (fieldbus Control system) appears in the later stages of DCS development. With the enhancement and popularization of the performance of the MCU of the embedded digital processor, the industrial Ethernet and the TCP/IP become hot spots of the field bus. For large-scale measuring point application occasions, centralized installation and protection of control equipment, namely installation and use in an electronic room are always the main modes, FCS does not play a role in eliminating the electronic room, and FCS has no obvious advantages in competition with DCS. Another weakness of FCS compared to DCS is the price, which is significantly higher than DCS per single measurement point, especially the MCU of each intelligent unit in FCS requires extra cost for special communication interface in addition to its powerful performance.

The inventor has appreciated that the chip UPD350, as a 32-bit high-performance MCU, is also well suited for intelligent input/output (I/O) nodes in the CCS field, as well as a multi-role MCU in a networked, digitized unit, in addition to its original design orientation as an intelligent USB charging controller.

Under the condition that specific node control is realized by using components such as a UPD350 chip and the like, the conventional FCS still adopts a centralized installation mode among electrons, and cannot be matched with a single MCU chip to realize the aim of eliminating electrons.
