Description

Two-way communication method and device for hydrogen fueling including improved safety check-in procedure Technical Field The present disclosure relates to a communication technology for hydrogen fueling from a station or dispenser to a hydrogen fuelling mobile body, and more particularly, to a hydrogen fuelling process capable of improving safety, compatibility, efficiency and reliability of hydrogen fuelling, a bidirectional communication method for the hydrogen fuelling process, and an apparatus using the bidirectional communication method. Background The statements in this section merely provide background information related to exemplary embodiments and may not provide any of the prior art. A hydrogen vehicle or a hydrogen electric vehicle refers to a zero-emission vehicle that is powered by electric energy generated by a reaction between high-pressure hydrogen gas stored in the vehicle and atmospheric air. Hydrogen electric vehicles are also known as Fuel Cell Electric Vehicles (FCEVs). Most hydrogen electric vehicles use hydrogen as an energy source to generate electricity using a fuel cell system. Among the hydrogen electric vehicles, only pure water (H 2 O) is discharged during power generation, and the hydrogen electric vehicle has an advantage of removing ultrafine dust from the atmosphere during traveling, and thus, the hydrogen electric vehicle is regarded as an environmentally friendly moving body of the next generation. Hydrogen electric vehicles are widely recognized as a technology with potential for use across various industries based on the fact that hydrogen exists on earth indefinitely as a fuel and the energy generation process is environmentally friendly. The hydrogen fuel moving body refers to a moving body that generates electric energy using hydrogen as an energy source or fuel and drives a motor using the electric energy. The hydrogen fuel moving body may include not only the above-described hydrogen electric vehicle but also an overhead moving body, an industrial truck, a train, a ship, and an airplane, and may include a device that generates electric energy using hydrogen as fuel and operates using the electric energy. Most hydrogen electric vehicles deliver high-pressure hydrogen gas safely stored in a hydrogen fuel storage tank and oxygen gas introduced through an air supply system to a fuel cell stack, and generate electric power through an electrochemical reaction between the hydrogen gas and the oxygen gas. The generated electric energy is converted into kinetic energy via the driving motor to operate the hydrogen electric vehicle, and the hydrogen electric vehicle traveling on the road discharges pure water only through the discharge outlet. Meanwhile, the concept of a hydrogen-fueled vehicle that is not a hydrogen electric vehicle also refers to a vehicle that uses hydrogen as a fuel, and the hydrogen-fueled vehicle uses heat generated by directly combusting hydrogen in an Internal Combustion Engine (ICE) to run an electric motor. The method of supplying hydrogen fuel to a hydrogen fuelled automobile is not significantly different from the method of supplying hydrogen fuel to a hydrogen electric vehicle. In the control technology for supplying hydrogen to a vehicle using hydrogen as a fuel, the final control objective is to operate a Compressed Hydrogen Storage System (CHSS) of a fuel cell within a limit temperature and a limit pressure required for safety of hydrogen fueling. In the past, when wireless or wired communication technology and calculation technology for control are not mature, conventional hydrogen electric vehicle hydrogen fueling processes, control technology, and protocols for hydrogen fueling processes have been defined, and thus, conventional technology cannot appropriately reflect the progress of recently developed Information and Communication Technology (ICT). Thus, conventional hydrogen fueling techniques for hydrogen electric vehicles are inefficient, slow, and unsuitable for high volume hydrogen fueling. In particular, in hydrogen fueling communication, most hydrogen fueling control equipment uses unidirectional infrared communication means in wireless communication, and therefore, even in wireless-based hydrogen fueling communication, limitations and drawbacks of unidirectional communication still exist. Disclosure of Invention Technical problem In order to solve the above-described problems, an object of the present disclosure is to provide a hydrogen fueling process of a hydrogen fueling moving body, and in a communication protocol for the hydrogen fueling process, to provide a hydrogen fueling process capable of overcoming limitations and disadvantages of conventional one-way communication and improving safety, compatibility, efficiency, and reliability of the hydrogen fueling, a communication protocol negotiation for the hydrogen fueling process, a fueling protocol negotiation, a fueling parameter negotiation method, a monitoring control meth
