The invention discloses a gas source processing triplet with a network interface and a method for determining normality of a gas source, and the gas source processing triplet is composed of several gas source nodes, a database and a dispatch controller; the gas source nodes comprise a sensor, a sensor data processing module and a wireless network communication device; the dispatch controller comprises a wireless signal processing module, a processor, a register and a gateway; the several gas source nodes are connected and communicated to the dispatch controller through WSN network, and the database is connected and communicated to the dispatch controller; the data collected by the sensor is transmitted to the sensor data processing module through a single bus, and the information is transmitted to the dispatching controller through the wireless network communication device and WSN network, and stored in the database; finally, the upper computer receives the information, displays the gas source information and judges whether the gas source is normal, so that whether to replace the filter, whether the pressure is normal, and whether the gas source processing element is working normally are determined according to the obtained specific information of the gas source.
