Below low-consumption wireless communication detecting device is specifically introduced, it is emphasized that, it is described below
Content be only optimal way, be not intended to limit the present invention:
(1) Infrared Detectors
Infrared Detectors is installed on reclaimer box house certain height position, such as, reclaimer casing
Internal total height is 5 meters, and Infrared Detectors is mountable to 4.5 meters of height and positions, is used for detecting reclaimer casing
Internal old and useless article has arrived 4.5 meters of positions the most, thus reflects that reclaimer box house is the most close
The state filled.Herein, it is used for detecting whether reclaimer box house is close to dress due to Infrared Detectors
Full state rather than have been filled with state, can be that cleaning worker goes to collection site to recycle old and useless articles

During run into and reflect when blocking article or cabinet wall, the infrared light being reflected back is by infrared receiver two pole
Pipe receives, and after being then passed through operational amplifier and rectifying detector process, obtains infrared actual voltage signal,
It is input to the positive input terminal of comparator again；Whether comparator more infrared actual voltage signal intensity is more than infrared
Reference voltage signal intensity, if it does, show that reclaiming box house article has arrived infrared transmitter installation
The position of height, therefore, the infrared light that infrared transmitter sends only is propagated relatively short distance and is i.e. run into and block article
And reflect, so infrared actual voltage signal intensity is stronger；If it is lower, show to reclaim box house
Article do not arrive the position of infrared transmitter setting height(from bottom), and therefore, the infrared light that infrared transmitter sends is propagated
Relatively long distance, just reflects, so infrared actual voltage signal intensity is more weak until running into cabinet wall.
Therefore, when hot outer actual voltage signal intensity is more than infrared reference voltage signal intensity, comparator output is low
Level is to central processing unit；When hot outer actual voltage signal intensity is less than infrared reference voltage signal intensity,
Comparator output high level is to central processing unit, such that it is able to make central processing unit detect, monitored casing is
No reach close to the state filled.
