Double-point fixed type power frequency electromagnetic field intensity combined alarm system and operation method thereof

Abstract

The invention provides a double-point fixed type power frequency electromagnetic field intensity combined alarm system and an operation method thereof, and belongs to the technical field of power frequency electromagnetic field intensity monitoring and alarming. The system comprises a power frequency electromagnetic field intensity detection device, a production control center data processor, an alarm center data processor, a ventilation device and a mobile terminal. According to the invention, inspection and onsite working frequency of workers can be reduced; occupational diseases of the workers, and contact time and contact intensity of harmful factors are reduced; alarms are timely given out, thereby facilitating timely maintenance of devices and increasing of service lifetime of the devices, it is ensured that devices can be in good use states for a long time, shut-down overhaul frequency is reduced and safe production time is increased; casualty accidents of personnel are reduced; an accident and abnormal situation database is established, so cost required for the accidents and the abnormities is reduced and disposal time is reduced; and through the accumulation of big data, data abnormity reasons are judged, load conditions of the devices are known and when parts of the devices are in a high-load condition for a long term, companies can be reminded for increasing the number of the devices, so load of the single device can be reduced.

AI Technical Summary

Problems solved by technology

[0005] Compared with the combination of human inspection and equipment monitoring, the initial investment of human inspection is low, and the follow-up investment is high. The accumulation of abnormalities is not discovered by the inspectors until an accident occurs. In severe cases, it will lead to production stoppage and social and economic
