Full-automatic hydrogen receiving and filling system of hydrogen refueling station

Abstract

The invention provides a full-automatic hydrogen receiving and filling system of a hydrogen refueling station. The full-automatic hydrogen receiving and filling system comprises a vehicle automatic identification subsystem, a voice prompt and ground light subsystem, a hydrogen robot automatic receiving subsystem and a filling device. The vehicle automatic identification subsystem comprises a field automatic shooting function camera, an entrance guard device and a vehicle information control system, and vehicle information comprises vehicle license plate numbers, transportation units, transportation vehicle conditions and medium parameter conditions. The voice prompt and ground light subsystem comprises a ground sensor, a light indication subsystem and a voice subsystem. The full-automatic hydrogen receiving and filling system has the beneficial effects that the system can integrate a current hydrogen filling machine, personnel and operation; and meanwhile, the change of technological parameters in the filling process is detected in real time, so that the filling safety is ensured, the filling efficiency is improved, and the personnel cost is reduced.

Description

technical field [0001] The invention relates to the field of hydrogen refueling stations, in particular to a fully automatic hydrogen receiving and filling system for a hydrogen refueling station. Background technique [0002] At present, all hydrogen refueling stations on the market use long-tube trailers (TT vehicles) to reach the hydrogen unloading site of the hydrogen refueling station. The hydrogen refueling station sends 2 employees to guide the TT vehicle into the warehouse, connect the hydrogen unloading hose, test the hydrogen dew point, and then purge And replace the hydrogen unloading hose, finally open the control valve, observe for 20 minutes before leaving if there is no abnormality, the whole process requires 2 people to follow and operate, confirm and observe, the whole process takes 40-60 minutes. In the whole process, paper records of hydrogen detection data (dew point, pressure, temperature and other parameters) are still used, as well as operation process...

AI Technical Summary

Problems solved by technology

In the whole process, paper records of hydrogen detection data (dew point, pressure, temperature and other parameters) are still used, as well as operation process confirmation. At the same time, there are safety risks and quality data of hydrogen leakage caused by personnel operation errors and irregular operations. Problems such as non-standard records, and increase the cost of 2 personnel and time costs

The hydrogen filling process is that after the hydrogen is pressurized by the compressor, it is controlled by the hydrogen pipeline and the manual hydrogenation equipment. The hose is connected to the hydrogen storage bottle of the fuel cell vehicle. Two hydrogenation personnel on site perform the hydrogenation operation and turn on the hydrogenation Valve, start the compressor, and then refill the hydrogen fuel cell vehicle. When the refill reaches a certain amount or pressure, manually shut down and disconnect the hydrogenation hose. The whole process requires personnel to check the whole process to detect hydrogen leakage. Filling temperature changes, to ensure that the filling rate is not too large, but also not too small to affect the filling efficiency, wasting manpower and a lot of time and energy
