Problems solved by technology

Although the above BEB algorithm can solve the delay problem caused by data collision, when n>10, the waiting time is too long and the data transmission delay jitter is too much, which is not conducive to the solution of real-time problems
In addition, there are still problems such as voltage incompatibility and weak anti-interference in the application of the existing protocol conversion gateway in the field of ships.

Embodiment Construction

[0035] Such as figure 1 , a conversion method of a protocol conversion gateway, the method realizes the conversion of the protocol through the gateway, and the method comprises the following steps:

[0036] Step 1: The power module works to reduce the voltage to the working voltage of each module and drive the circuit.

[0037] Step 2: The command sent by the upper computer is received by the Ethernet module, and the electrical signal is converted into data and stored in the receiving array in the controller module 3 .

[0038] Step 3: The controller module analyzes the data in the receiving array according to the protocol to extract valid data, and stores the valid data in the sending array in the controller module.

[0039] Step 4: The sending array in the controller module sends the data to the data transceiver module, and through the magnetic isolation of the data isolation module integrated in the same chip, the data is converted into a differential signal and transmitte...

Abstract

The invention discloses a conversion method of a protocol conversion gateway. The conversion method mainly improves the Binary Exponential Backoff (BEB) algorithm of the CSMA / CD protocol in the existing gateway, and re-constrains the message backoff time. In order to realize the protocol conversion transmission. The method can effectively reduce the delay jitter under data overload and improve the real-time performance of data transmission. The invention also has the characteristics of strong anti-interference and suitable for marine use.

Description

technical field [0001] The invention relates to the field of communication protocol conversion, in particular to a conversion method for a protocol conversion gateway suitable for industrial Ethernet communication. Background technique [0002] Fieldbus technology is rich in categories, such as RS485, RS232, CAN bus. Due to the different structures and protocols of different buses, the communication between different bus devices needs to convert different bus protocols through protocol conversion gateways to realize the interconnection and intercommunication of different communication interfaces. Due to the narrow space of the ship engine room (the area with dense equipment on board), the equipment arranged in this space is compact in layout, and the signals interfere with each other seriously. At the same time, when the protocol converter processes the data from each bus, it needs to process the data, so the real-time performance of the signal is very important. The binary...
