Description

Technical Field

[0001] This invention relates to the field of intelligent control technology for hydrogen refueling, specifically to a vehicle-station bidirectional interactive collaborative control system for the hydrogen refueling process. Background Technology

[0002] Existing hydrogen refueling station control systems mostly employ a one-way command transmission mode, where only the vehicle sends a refueling request, and the refueling station executes the refueling process according to fixed parameters. This mode cannot achieve two-way real-time data interaction between the vehicle and the station. This mode has many drawbacks: First, the station cannot obtain the real-time operating status of the on-board hydrogen storage tanks, which can easily lead to overheating and overpressure refueling safety risks. Second, the refueling parameters lack precise algorithm support, making them unable to be adaptively adjusted, resulting in low refueling efficiency and easy equipment damage. Third, the communication method does not take into account explosion-proof requirements and protocol compatibility, making it difficult to adapt to different vehicle models. Furthermore, it lacks a two-way vehicle-to-station identity verification and data traceability mechanism, which cannot meet the industry's safety supervision and acceptance requirements. At the same time, existing technologies are easily circumvented by competitors, making it difficult to form a technological protection barrier. Summary of the Invention

[0003] This invention addresses the shortcomings of existing technologies by providing a vehicle-station bidirectional interactive hydrogen refueling process collaborative control system. This system solves the problems of poor safety, low efficiency, untraceable data, and susceptibility to circumvention associated with traditional unidirectional hydrogen refueling control. It enables bidirectional collaborative, safe, controllable, and highly efficient hydrogen refueling operations throughout the entire vehicle-station process, while also meeting industry acceptance and patent protection requirements.

[0004] Technical solution

[0005] System overall structure: On-board hydrogen system terminal (100) Vehicle-mounted controller (101) The hydrogen storage tank assembly sensor unit (102) includes a pressure sensor, a temperature sensor, and a leak detection sensor. Wireless communication unit (103) Identity authentication chip (104) Hydrogen refueling machine interaction module (200) Wireless communication interface (201) Data transmission unit (202) Hydrogenation control execution unit (203) Emergency stop interlocking unit (204) Multiprotocol parsing unit (205) Station-side edge control host (300) Two-way data verification module (301) Dynamic parameter calculation module (302) Safety interlock control module (303) Local storage and communication unit (304) Cloud-based collaborative management platform (400) Data storage unit (401) Regulatory traceability unit (402) Report generation unit (403) Workflow

[0006] After the vehicle stops at the hydrogen refueling station, the on-board hydrogen system terminal (100) and the hydrogen refueling machine interaction module (200) establish a connection through a short-range intrinsically safe wireless or contact interface to complete two-way identity authentication and verify the vehicle and hydrogen refueling station qualification information. The hydrogen storage cylinder group sensor unit (102) collects cylinder group pressure, temperature and leakage data in real time. After being processed by the vehicle controller (101), the data is uploaded to the hydrogen refueling machine interaction module (200) in real time through wireless encrypted communication. The multi-protocol parsing unit (205) identifies the communication protocol of the compatible vehicle model, converts heterogeneous data into a standard format, and transmits it synchronously to the station edge control host (300), while uploading the operating parameters of the station's compressor, hydrogen storage, and cooling system. The two-way data verification module (301) performs real-time comparison of vehicle-station data. If the data matches, the hydrogen refueling process begins. If the data deviation exceeds the standard, an interlock shutdown is immediately triggered. The dynamic parameter calculation module (302) adaptively calculates the hydrogenation pressure, flow rate, and pre-cooling temperature based on the temperature rise rate and initial pressure of the on-board bottle group, combined with the thermodynamic filling model, and generates control commands to be sent to the hydrogenation control execution unit (203). During the hydrogen refueling process, the vehicle and station continuously exchange data in both directions and dynamically adjust the hydrogen refueling parameters. When abnormalities such as over-temperature, over-pressure, leakage, or communication interruption occur, the safety interlock control module (303) drives the emergency stop interlock unit (204) to cut off the gas source. The entire hydrogenation process data is synchronously uploaded to the cloud-based collaborative management platform (400) to complete data storage, regulatory traceability, and compliance report generation.

Detailed Implementation Example 1

[0010] The vehicle-mounted hydrogen system terminal (100) is integrated and installed in the hydrogen storage compartment of the hydrogen commercial vehicle. The hydrogen storage cylinder group sensor unit (102) is connected to the vehicle-mounted hydrogen storage cylinder group to complete the wiring and debugging. After the vehicle enters the hydrogen refueling station, the vehicle-mounted hydrogen system terminal (100) is paired with the hydrogen refueling machine interaction module (200) through short-range intrinsically safe wireless and completes two-way qualification verification through the identity authentication chip (104). The multi-protocol parsing unit (205) automatically adapts to the vehicle communication protocol. The vehicle-mounted terminal uploads cylinder group pressure, temperature and temperature rise rate data in real time. The station edge control host (300) calculates the hydrogen refueling parameters in combination with the thermodynamic filling model. The hydrogen refueling machine completes the refueling according to the dynamic parameters. The data is synchronized bidirectionally throughout the process. In case of abnormality, the system will stop immediately. The hydrogen refueling data is uploaded to the cloud for filing. Example 2

[0011] This system is applied to newly built standardized hydrogen refueling stations. The hydrogen refueling machine interaction module (200) is integrated into the hydrogen refueling machine, and the station-side edge control host (300) is installed in the station control cabinet, connecting to the existing compressor, cooling, and hydrogen storage equipment in the station. For different brands and models of hydrogen fuel cell vehicles, the system automatically completes protocol adaptation through a multi-protocol parsing unit, without the need to modify the equipment in the station and the vehicle terminal, realizing unattended intelligent hydrogen refueling. No manual intervention is required throughout the process, and the generated hydrogen refueling data reports are directly used for safety acceptance and operation audit. When the network is interrupted, the system independently completes the entire process control based on the local edge control host to ensure hydrogen refueling safety.
