The invention discloses a combined control method and system for unloading gas from a high-pressure pipe bundle vehicle to a gas unloading column. The combined control method comprises the following steps that a first controller of the high-pressure pipe bundle vehicle establishes communication connection with a second controller of the gas unloading column, after a gas unloading pipe of the high-pressure pipe bundle vehicle is connected with a hydrogen inlet pipe of the gas unloading column, the first controller and the second controller are triggered to generate gas unloading preparation signals, after the second controller generates the gas unloading preparation signal, a purging system of the gas unloading column is controlled to purge a pipeline in the gas unloading column, after purging is completed, the second controller generates a gas unloading signal and sends the gas unloading signal to the first controller, and the first controller and the second controller control the high-pressure pipe bundle vehicle and the gas unloading column to perform hydrogen unloading operation. According to the combined control method and the system for unloading gas from the high-pressure pipe bundle vehicle to the gas unloading column, the hydrogen unloading operation can be automatically carried out, the safety is improved, and manpower is saved.
Description
technical field [0001] The invention relates to the technical field of hydrogen unloading control, in particular to a combined control method and system for unloading gas from a high-pressure tube bundle vehicle to an unloading column. Background technique [0002] With the application and promotion of hydrogen fuel cells, more and more cars use hydrogen fuel cells, and hydrogen refueling stations have become an important infrastructure for popularizing hydrogen fuel. [0003] The current hydrogen refueling station basically uses a hydrogen tube bundle vehicle as a means of hydrogen transportation. The hydrogen tube bundle vehicle transports the hydrogen from the hydrogen production plant to the hydrogen refueling station, and uses the unloading column to transport the hydrogen in the tube bundle vehicle to the storage tube bundle of the hydrogen refueling station. Usually, the tube bundle pressure of the hydrogen tube bundle truck is about 20MPa, but the connection between ...
