Abstract
The utility model discloses a programmable far infrared automatic dust-fall atomization control device which is formed by a stabilized voltage power supply circuit, a far infrared inductive sensor, a logic control circuit, a microprocessor, an amplification drive circuit and an electric ball valve by communicating connection. The programmable far infrared automatic dust-fall atomization control device senses an infrared signal of a human body by the far infrared inductive sensor, realizes start, stop and automatic atomization in regular time and ensures the safety of workers.
Description
Technical field
The utility model relates to device for reducing dust under the coal mine.
Background technology
Mainly advance back under the coal mine at present, place dust guards such as Feng Daxiang, ginney are opened by manual work, when the staff got into the tunnel, the frequent phenomenon of forgetting unlatching influenced operating environment.
Summary of the invention
The utility model is to overcome artificial deficiency of opening, and has designed a kind of automatic dustfall atomization mechanism.
For achieving the above object, the automatic dustfall atomization mechanism of the utility model is formed by connecting voltage-stabilized power supply circuit, far infrared rays inductive pick-up, logic control circuit, microprocessor, amplification driving circuit and electrical ball valve communication; Wherein,
Described voltage-stabilized power supply circuit adopts the L7805 integrated chip;
Described logic control circuit adopts the HD74LS02 logic chip;
Described microprocessor adopts the AT8951 single-chip microcomputer;
Described far infrared rays inductive pick-up adopts infrared sensing special IC BISS0001.
The utility model is realized regularly opening, stopping through far infrared inductive pick-up induction human infrared signal, and auto spraying has guaranteed staff's safety.
Description of drawings
Fig. 1 is the circuit block diagram of the utility model embodiment.
The specific embodiment
As shown in Figure 1, the utility model is formed by connecting voltage-stabilized power supply circuit, far infrared rays inductive pick-up, logic control circuit, microprocessor, amplification driving circuit and electrical ball valve communication; Its operating principle is: during normal condition, microprocessor is periodically exported high and low level signal by predefined delay time; Through amplification driving circuit; Make periodically adhesive of relay, release, the control electrical ball valve is opened, closing motion, realizes the self-timing spraying.Simultaneously, microprocessor carries out the certain hour time-delay, judges that after personnel passed through, the output control signal made relay adhesive again, opens electrical ball valve, begins spraying.
