Negative oxygen ion monitoring system

The utility model belongs to the technical field of negative oxygen ion monitoring, and particularly relates to a negative oxygen ion monitoring system which comprises a detector body, the top of the detector body is fixedly communicated with an air inlet pipe, and the top of the detector body is fixedly provided with an audible and visual alarm. According to the negative oxygen ion monitoring system, by arranging the filtering monitoring mechanism, when the negative oxygen ion monitoring system is used, after a large amount of dust and impurities are accumulated on a filter screen in a functional pipe to cause blockage, the air speed entering an air inlet pipe through an induced draft fan is reduced, and after a miniature air speed sensor detects that air speed data information is lower than a set value, the air speed is monitored. After the negative oxygen ion detector is started, the negative oxygen ion is fed back to the controller in the negative oxygen ion detector body, and the controller in the negati
