In some possible implementations, the exception handling logic provided herein may include alarm logic and alarm data upload logic. In particular, the alarm logic may comprise the steps of: configuring an alarm condition of an acquisition point, and if the acquisition point value is greater than a preset value, sending alarm information; the gateway saves the alarm information and a database; when data is collected, when the data is monitored to be checked and alarmed, reading alarm information in a database, and if the alarm condition is met, sending the alarm information to the database; and skipping not to process if the alarm condition is not met. The reporting process of the alarm information is the same as that of the data, only the alarm information is reported preferentially, and the collected related parameter information is reported after the alarm information is reported.

Specifically, the first preset pressure is used for representing a numerical range reaching the alarm, but does not reach a dangerous numerical range, and indicates that the current pressure is abnormal, but the pressure is not in a dangerous interval, and the first preset pressure can be temporarily stored in a storage module of the monitoring device and is to be centrally uploaded to the server. The second preset pressure is used for indicating that the current pressure reaches a dangerous range and immediate measures are required. And therefore immediately sent to the server. Or to the relevant terminal. Thus, it can be appreciated that the intensity of the alarm represented by the first alarm information is less than the intensity of the alarm represented by the second alarm information. Meanwhile, the relevant parameters of the gas system such as flow, temperature and the like can be monitored by adopting the logic, and the application does not limit the type of the specific monitoring parameters.

Optionally, the gas remote monitoring method in the embodiment of the present application further includes:

acquiring accumulated time length;

Specifically, those skilled in the art can upload parameters and upload exception information by adding a time attribute. The setting of the period of time may be a real-time period, a fixed local period, or a non-fixed period. According to the use frequency or the importance degree of the system in different time periods, the time periods with different interval lengths are set, so that the system requirements are met, and meanwhile, diversified selections are provided.

acquiring a first temperature of a gas system;

In some possible embodiments, the first temperature is format converted and packaged and then sent to the server. It can be understood that the collected first temperature may be packaged and partitioned according to the actual range of the temperature, the temperature collecting device, the temperature collecting time, and other factors, and sent to the server. Through operations such as conversion packing, data transmission speed is improved, and data processing efficiency is improved. Of course, parameters such as pressure and flow rate may be processed by the processing logic, and the application is not limited thereto.
