Unpowered natural gas filling station with cycle alternate control system and control method

Abstract

The invention provides an unpowered natural gas filling station provided with a cyclic and alternate control system and a control method. Based on a cylinder twining pipe bundle type container trailerassembly provided with an interconnected controllable valve pipeline system, opening-closing regulation and control of valves of independent gas cylinders connected to all gas collection pipes and switching connection between the independent gas cylinders and the gas collection pipes are achieved by detecting the pressure states of all the gas collection pipes, switching of pipelines and gas cylinders between trailers are achieved, and an independent gas cylinder cyclic and alternate switching sequence table and a special memory for pressure switching values are stored in a valve management and control module of the trailer assembly. According to the unpowered natural gas filling station provided with the cyclic and alternate control system and the control method, the time for parking twotrailers at the same time is shortened, and the trailers can have more time to travel to a primary filling station for gas filling.

Description

technical field [0001] The invention relates to a natural gas filling station and a control method, which belong to the technical field of natural gas application, in particular to a non-powered compressed natural gas filling station with a gas bottle circulation alternate control system and a control method. Background technique [0002] With the country's environmental governance, in order to prevent air pollution, it is imminent to control the exhaust of fuel vehicles. Electric vehicles and gas vehicles will gradually replace fuel vehicles. At present, the public transport systems of major cities have gradually adopted natural gas instead of fuel oil as the main power source of vehicles, and the construction of natural gas refueling stations in various places will flourish. [0003] At present, there are two types of natural gas vehicle refueling stations commonly used at home and abroad: 1) the gas refueling stations that use natural gas from the pipeline transportation ...

Problems solved by technology

[0015] In order to solve the technical problem of low filling efficiency and slow speed of the current non-powered gas filling station, the present invention provides a non-powered natural gas filling station with a cycle alternate control system and a control method, through the valve of a single independent gas cylinder Opening and closing control and control of pipeline valves increase the number of combinations of gas cylinders, increase the utilization rate of gas cylinders, increase the filling rate, and reduce the filling time of bicycles, so as to gain more time for bicycles to go to the mother station to inflate ; and by setting a three-way controllable valve pipeline between the two trailers, the switching connection with the gas dispenser is realized, saving manpower
