Integration controller of refueling machine and communication protocol updating method used by same

Abstract

The invention provides an integration controller of refueling machines and a communication protocol updating method used by the integration controller. Communication connection between a host and a plurality of different types of refueling machines is established through the integration controller; the integration controller mainly comprises a main control board and a plurality of control circuit boards; and when one control circuit board is replaced, according to the type of the refueling machine connected with the control circuit board to be replaced, a communication protocol corresponding to the type of refueling machine and stored in the control circuit board to be replaced is started for use, so that after the control circuit board is replaced, the control right over a rear refueling machine is smoothly obtained. By controlling the main control board, a plurality of same control circuit boards are enabled to start using different communication protocols, so that the integration controller can be respectively connected with different types of refueling machines and control different types of refueling machines. Therefore, the dilemma that a variety of refueling machine controllers exist in the prior art and are not compatible with one another is replaced; and all the control circuit boards perform a hot swapping function, so that the problem that when a conventional refueling machine controller is damaged, the replacement or the maintenance can be conducted only after all the refueling machines are closed can be solved.

Description

technical field

[0001] The invention relates to a fuel dispenser controller, in particular to a method for updating a communication protocol of the fuel dispenser controller. Background technique

[0002] Most of the means of transportation that the general public rides, such as motorcycles or automobiles, use petroleum as fuel. And when the fuel is exhausted, it is necessary to go to a general gas station or gas filling station to replenish the fuel. Therefore, in countries with well-developed transportation, the location, quantity, and quality of these refueling (gas) stations have become an important key to the development of transportation.

[0003] Such as figure 1 As shown, it is a schematic diagram of gas station configuration in the prior art. A general gas station is mainly composed of a back-end host 1, which is connected to a plurality of controllers 2 and 3 of different types (usually different brands) through a plurality of different communication protocols, ...
