Embodiment 1

[0039] use figure 1 The system and method, the pressure pipeline is a group, fill 200 yuan of hydrogen, press the filling button, start filling, judge whether the pressure of the low-pressure pipeline PT-603 is less than 35Mpa-75Mpa, if it is less than open the bypass valve SV-6010.5 seconds , to collect and judge whether the pressure of the gas storage tank PT-601 is less than 1Mpa or greater than or equal to 35Mpa (less than 1Mpa indicates that there is a leak, and equal to 35Mpa indicates that the gas storage tank is full), and if so, stop hydrogenation.

Embodiment 2

[0041] use figure 1 The system and method, the pressure pipelines are two groups, add 200 yuan of hydrogen, press the filling button to start filling, when there are two pressure pipelines, judge whether the pressure of the low-pressure pipeline PT-603 is less than 35Mpa-75Mpa, if it is less than Then open the bypass valve SV-60 for 10.5 seconds, collect and judge whether the pressure of the gas storage tank PT-601 is less than 1Mpa or within the range of 35Mpa-75Mpa (less than 1Mpa means there is leakage, and the range of 35Mpa-75Mpa indicates that the gas storage tank is full ), if it is, stop the hydrogenation, otherwise start to judge whether the pressure difference between the low-pressure pipeline and the gas storage tank PT-603 minus PT-601 is greater than 5Mpa, if it is, open the SV-602, start metering, and check whether the pressure of the low-pressure pipeline PT-603 is If it is not less than 35Mpa, close the bypass valve SV-601, judge whether the pressure of the gas...

Embodiment 3

[0043] use figure 1 The system and method, the pressure pipeline is divided into three groups, fill 200 yuan of hydrogen, press the filling button to start filling, the hydrogenation process is: judge whether the pressure of the low pressure pipeline PT-603 is less than 35Mpa-75Mpa, if it is less than, open the side Open the valve SV-60 for 10.5 seconds, collect and judge whether the pressure of the gas storage tank PT-601 is less than 1Mpa or within the range of 35Mpa-75Mpa (less than 1Mpa indicates that there is leakage, and the range of 35Mpa-75Mpa indicates that the gas storage tank is full), if If yes, stop hydrogenation, otherwise start to judge whether the pressure difference between the low-pressure pipeline and the gas storage tank PT-603 minus PT-601 is greater than 5Mpa, if yes, turn on SV-602, start metering, and check whether the pressure of the low-pressure pipeline PT-603 is less than 35Mpa, If it is not less than 35Mpa, close the bypass valve SV-601, judge whet...

Abstract

The invention provides an electric control system of a hydrogen gas adding machine and a gas adding method thereof. The system comprises a power supply and battery management module, a gas adding machine central control module, an operation executing mechanism module, a transaction information reading-writing-displaying module and a communication module. The power supply and battery management module, the operation executing mechanism module, the transaction information reading-writing-displaying module and the communication module are connected with the gas adding machine central control module. The operation executing mechanism module comprises an electromagnetic valve, an array type input keyboard and an emergency stopping operation button. The transaction information reading-writing-displaying module comprises a liquid crystal information display screen, a gas adding machine price and adding amount display screen, and an IC card information reader-and-writer. The communication module comprises a POS machine, a printer and a flowmeter sensor. According to the electric control system, modular type selecting and designing are utilized; and the modules are connected through cables, thereby realizing clear hardware structure and high convenience in fault removing and maintenance.

Description

technical field [0001] The invention relates to an electric control system of a hydrogen filling machine and a filling method. Background technique [0002] Hydrogen is recognized as the cleanest energy source on earth. It has the characteristics of colorless, odorless, and non-toxic. After burning hydrogen, it will generate water without any pollution, and it can release huge heat. Therefore, it is an advanced and promising energy source. [0003] With the wide application and rapid development of hydrogen energy technology in China, the market demand for hydrogen filling machines is increasing. At the same time, the research and application of hydrogen filling machines are also developing at a high speed. Many domestic enterprises are conducting research and improvement of hydrogen filling machines through the combination of independent innovation and technology introduction. At the same time, with the development of technologies such as embedded technology, touch screen...
