Embodiment Construction

[0009] An automatic control method for hydrogen-natural gas filling station equipment, the method is realized by the following steps: (1) Three storage tanks are installed at the hydrogen-natural gas filling station, and the three storage tanks are filled with gas respectively, so that the three storage tanks The pressure of each storage tank has reached its rated pressure; (2) During the operation of the hydrogen-natural gas filling station, the pressure of the three storage tanks is constantly changing, among which the storage tank with the highest pressure acts as a high-pressure storage tank, and the pressure is in the middle The storage tank with the lowest pressure acts as a medium-pressure storage tank, and the storage tank with the lowest pressure acts as a low-pressure storage tank; (3) When a car comes to the hydrogen-natural gas filling station to refuel, first fill the car's gas cylinder through the low-pressure storage tank, and then Inflate the car's on-board gas ...

Abstract

The invention relates to a control method of a device in a hydrogen-natural gas filling station, in particular to an automatic control method of a device in a hydrogen-natural gas filling station. The invention solves the problems of frequent starting and stopping of equipment and influenced working efficiency of the equipment of the traditional control method of the hydrogen-natural gas filling station device. The automatic control method of the hydrogen-natural gas filling station device comprises the following steps of: 1, setting three storage tanks on a hydrogen-natural gas filling station, respectively charging gas into the three storage tanks; 2, in a process of operating the hydrogen-natural gas filling station, using the storage tank with a highest pressure as a high-pressure storage tank; 3, charging gas to a vehicle-mounted cylinder of a vehicle through a low-pressure storage tank, charging gas to the vehicle-mounted cylinder of the vehicle through a medium-pressure storage tank; and when the pressure of the low-pressure storage tank is lower than half of a rated pressure of the low-pressure storage tank, charging gas to the low-pressure storage tank. The invention is suitable for carrying out automatic control on the device of the hydrogen-natural gas filling station device.

Description

technical field [0001] The invention relates to a method for controlling equipment of a hydrogen-natural gas filling station, in particular to an automatic control method for equipment of a hydrogen-natural gas filling station. Background technique [0002] During the operation of the hydrogen-natural gas filling station (HCNG station), effective control of the working process of its equipment (storage tank) is the key to ensure the safe operation of the hydrogen-natural gas filling station. Due to the lack of integrity of the existing hydrogen-natural gas filling station equipment control method, when it is used for equipment control, the equipment often needs to be started and stopped frequently, which makes the equipment work efficiency low. Based on this, it is necessary to invent a brand-new hydrogen-natural gas filling station equipment control method to solve the problem that the existing hydrogen-natural gas filling station equipment control method easily leads to fr...
