Problems solved by technology

At this time, when any device needs to communicate with another device, it needs to go through two sets of conversion devices for secondary conversion, which brings about an increase in delay after conversion through various conversion devices, that is, each conversion generally has 1-5ms Delay, more fault points, more wiring harnesses, difficulty in finding fault points, increased cost, too much space occupied, etc.

Embodiment 1

[0018] Example 1: see Figure 1-Figure 4 , A conversion system that supports multiple communication buses at the same time. The conversion system includes a hardware platform and a software system. The hardware platform consists of an ARM processor 1, a power module 2, a data storage module 3, a data cache module 9, and two RS485 The transceiver module 5, the CAN transceiver module 6, and the Ethernet PHY chip 7 form a hardware platform. The data buffer module can increase the data processing capacity of the system and reduce the possibility of data buffer overflow. The ARM processor 1 communicates with The data storage module 3, the RS485 transceiver module 5, the CAN transceiver module 6, and the Ethernet PHY chip 7 are connected. The SPI peripheral pins are connected to the on-board cable socket and connected to other devices through the cable. This module is the main device of the device. Control module. The power supply module is used to supply power; the data storage modu...

Embodiment 2

[0019] Example 2: see Figure 1-Figure 3 , A method to support multiple communication bus conversion at the same time, the method is as follows: 1) Connect CAN, SPI, RS485, and Ethernet to the field bus respectively; 2) Configure the computer’s 485 interface with the device Interface connection, and use the configuration software to configure the priority of each interface data frame address bit, software layer conversion protocol and sending interface, and four communication interface communication parameter configurations such as baud rate, master-slave mode, etc., and store them in the storage module , The last configuration parameters are automatically loaded each time the power is turned on; 3) When a certain field bus sends data to the interface, the data frame enters the ARM processor and the application layer protocol module through the corresponding communication module, according to the settings of the interface and parameter configuration It can be MODBUSRTU protocol...

Description

Technical field [0001] The invention relates to a communication conversion device, in particular to a system and method for simultaneously supporting conversion of multiple communication buses into other multiple communication buses, and belongs to the technical field of communication buses. Background technique [0002] CAN is the abbreviation of Controller Area Network (CAN), and it is one of the field buses widely used internationally. SPI is the abbreviation of Serial Peripheral Interface. It is a high-speed, full-duplex, and synchronous communication bus. Because of its simplicity and ease of use, more and more chips integrate this kind of communication. protocol. RS485 is a widely used method of network layout. It is simple and convenient to implement. There are many instrument sensors that support RS485. And Ethernet (Ethernet) is the most common communication protocol standard adopted by existing local area networks. [0003] At present, these several communication metho...
