In the new standard, the security requirements for mobile phone payment have been added: "Customers can be allowed to use mobile phone payment in the refueling operation area equipped with combustible gas sound and light alarm device, and when the on-site alarm alarms, the use of mobile phones and refueling-related operations should be stopped immediately." Deleted "Mobile communication devices should not be used in gas stations".

The new standard stipulates: the operation site should be equipped with portable or mobile gas detection alarm instrument, continuous detection of oxygen, combustible gas and toxic gas concentration in the tank, when the gas concentration is found to exceed the standard, the operation should be stopped immediately, evacuate personnel, the site should be treated, and the operation can be resumed only after the analysis is qualified, if the operation is interrupted for more than 30min, the gas analysis should be re-carried out before re-entry.

The low-power infrared gas sensor launched by Guangyuan Technology has the characteristics of accurate measurement, long life, small drift and battery power supply, which can make the detector work in battery-powered mode for more than 5 years, and can be directly installed in gas station application scenarios to avoid the problem of stopping construction.

The electrochemical sensor launched by Guangyuan Technology covers more than 30 kinds of toxic gases, of which oxygen performance has reached the first echelon level of imports, leak-proof structure design, excellent long-term stability, and ultra-high cost performance can make portable four-in-one detector manufacturers create a more cost-effective machine.
