Filtering and absorbing device based on bang-bang control

Abstract

The invention relates to the technical field of filter absorbers, and discloses a filter absorber based on bang-bang control, which includes: a temperature sensor for collecting the ambient temperature of the filter absorber in real time and converting it into a temperature signal; a humidity sensor for The ambient humidity of the filter absorber is collected in real time and converted into a humidity signal; the power supply module is used to supply power to the filter absorber; the bang‑bang algorithm control module is used to receive temperature signals and humidity signals; the threshold adjustment module is used to provide power to the bang‑bang algorithm The bang algorithm control module sets the temperature threshold and the humidity threshold, and the bang-bang algorithm control module is used to compare the temperature signal and the humidity signal with the temperature threshold and the humidity threshold respectively, and when the ambient temperature exceeds the temperature threshold or the ambient humidity exceeds the humidity threshold Cutting off the power supply module and generating an alarm signal; and an alarm module, configured to receive the alarm signal for alarming. The invention can preferably improve the service life of the free exciter in the filter absorber.

Description

technical field [0001] The invention relates to the technical field of filter absorbers, in particular to a filter absorber based on bang-bang control. Background technique [0002] Filter absorbers play an important role in filtering out poisonous agents and poisonous smoke in the air-contaminated air in civil air defense fortifications during wartime. Since the free radical exciter in the filter absorber includes a large number of electronic components, it must meet a certain temperature and humidity threshold when working. If this threshold is exceeded, the exciter is prone to short circuit, moisture, failure, etc., which will damage the Its working life is seriously affected. In addition, the free radical generator is usually an embedded component and cannot be replaced. If its working life expires, the filter absorber can only be replaced as a whole, which will cause a lot of waste in the use and maintenance of the entire civil defense fortification during wartime.

Since the free radical exciter in the filter absorber includes a large number of electronic components, it must meet a certain temperature and humidity threshold when working. If this threshold is exceeded, the exciter is prone to short circuit, moisture, failure, etc., which will damage the Its working life has a serious impact on

In addition, the free radical exciter is usually an embedded component and cannot be replaced. If its working life expires, only the filter absorber can be replaced as a whole, which will cause a lot of waste in the use and maintenance of the entire civil air defense fortification during wartime

Since the basement has been in a low-temperature and high-humidity environment for many years, there are frequent cases of early overall replacement due to the expiry of the service life of the free radical generator while the service life of other components has not expired
