Problems solved by technology

[0012] (1) The detection switching circuit system is complex and costly, and the failure of the detection switching circuit will make the entire redundant control system unable to work normally
[0013] (2) In some occasions, it is necessary to exchange data between the master and the slave in real time to ensure that the slave can obtain the information of the controlled object in real time, but the use of the detection switching circuit in the traditional redundant system is not conducive to the real-time communication between the master and the slave

Abstract

This invention relates to CAN main line redundancy control system of fuel cell generating system, including the main engine and its the main line swicher, driven machine and its the main line awicher, the CAN main line, the implementing agency, the controlled object. Between the main engine and driven machine carries on the exchange of information using the CAN main line communication, in the normal condition, the main engine controls the controlled object through the implementing agency, thus when the main line swicher of main engine is open, the driven machine swicher is cut off, and when the main engine is in fault, the main line swicher of the main engine is cut off, the main line swicher of the driven engine is open so that the control to the object is completed by the driven engine.

Description

technical field [0001] The invention relates to a fuel cell, in particular to a CAN bus dual-machine redundant control system applied to a fuel cell power generation system. Background technique [0002] An electrochemical fuel cell is a device that converts hydrogen and oxidants into electrical energy and reaction products. The internal core component of the device is the membrane electrode (Membrane Electrode Assembly, referred to as MEA). The membrane electrode (MEA) is composed of a proton exchange membrane and two porous conductive materials, such as carbon paper, sandwiched between the two sides of the membrane. On the two boundary surfaces of the membrane and the carbon paper, there are even and finely dispersed catalysts for initiating electrochemical reactions, such as metal platinum catalysts. Conductive objects can be used on both sides of the membrane electrode to draw the electrons generated during the electrochemical reaction through an external circuit to for...
