Abstract

The invention provides an adaptive multi-protocol converter which comprises a main controller, CAN transmitting and receiving circuits, RS232 interface circuits, RS485 interface circuits and an Ethernet transmitting and receiving circuit, wherein the CAN transmitting and receiving circuits, the RS232 interface circuits, the RS485 interface circuits and the Ethernet transmitting and receiving circuit are externally connected with the main controller. Through the four interface modes, namely, RS232, RS485, CAN and Ethernet, the versatility and the reusability of the multi-protocol converter are achieved, iterative development and resource waste are reduced, and cost is saved.

Description

Technical field [0001] The invention relates to the field of communication technology, in particular to an automatic matching type intelligent multi-protocol converter. Background technique [0002] At present, with the widespread promotion of intelligent communication control technology, the use of automatic control equipment in various industries has become more and more common. However, due to the differences in the application fields of equipment, the production technologies involved have their own strengths and technical standards in many industries. It is not uniform, so in the process of large-scale system integration, communication interfaces and protocols between devices are often inconsistent. It takes a lot of effort to coordinate the communication interface protocols between different devices. One of the solutions is to select or develop a dedicated protocol converter, but the reusability is not high, which will lead to multiple repeated developments, a great waste of...
