The invention relates to a multi-network redundancy method for a system for testing the dynamic performance of a fuel cell vehicle, and the method comprises the following steps: 1), building a communication network for the system for testing the dynamic performance of the fuel cell vehicle; 2), building a redundancy communication network through employing a double-network redundancy mode, wherein the redundancy communication network comprises a main communication network and a standby communication network, a network card and line concentrator on a communication node in the communication network of the system are respectively provided with a main unit and a standby unit, and the main unit and the standby unit respectively communicate with the main communication network or the standby communication network through a corresponding network card and line concentrator. Compared with the prior art, the method is advantageous in redundancy double networks, load balance, high reliability and wide application range.
Description
technical field [0001] The invention relates to the technical field of network communication of a vehicle performance test system, in particular to a multi-network redundancy method for a fuel cell vehicle power performance test system. Background technique [0002] Fuel cell vehicles, due to their advantages of zero emission, high efficiency, clean fuel and renewable, are regarded as an important research and development direction for the sustainable development of the automobile industry. During the research and development of fuel cell vehicles, it is necessary to test its environmental adaptability, road driving condition adaptability, power system durability and reliability, and overall vehicle performance. Therefore, a set of laboratory testing equipment is needed which integrates the tested components of the fuel cell engine (including monomers, stacks, etc.), the core power components of the real vehicle, and the simulation system of the real vehicle road environment...
