Abstract
The invention belongs to the field of sensors, and particularly relates to an optically controlled sensor. The optically controlled sensor comprises a housing, and further comprises a lens, an induction component and a control circuit board, wherein the lens is fixedly connected to the housing; the induction component is connected with the control circuit board; and the control circuit board is mounted in the housing. The optically controlled sensor has the advantages that the sensitivity is high; error action is less; long-term continuous work can be realized; and concentrations of harmful gases can be reduced while air is purified through dust settling, so as to improve and manage a working environment.
Description
Technical field
The invention belongs to sensor field, relate in particular to the sensor of the atomizing de-dusting apparatus of installing in the big lane, a kind of colliery.
Background technology
Coal dust harm is called as one of colliery five the Nature disasters; Dust is to the wearing and tearing of plant equipment; Can bring unsafe factor to production, dust also possibly cause combustion explosion, causes economic loss; Dust also can cause damage to the workman is healthy simultaneously, and the serious harm of so-called dust is shown great attention to by people.In order to solve dust problem; The many atomizing de-dusting apparatus of installing in the down-hole of people; But present most equipment all is Artificial Control or timing controlled, when can not automated spray, particularly workman in big tunnel, down-hole, working; Spill the wet workman who is working or passing by during the atomizing de-dusting apparatus depositing dust easily, workman's work has been caused great inconvenience.
Summary of the invention
Be prone to squirt workman's problem when solving mining atomizing de-dusting apparatus depositing dust, the present invention provides a kind of light control sensor, can respond to the infrared light that human body sends, and controls atomizing de-dusting apparatus automatically and sprays.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of light control sensor, comprise shell, and it is characterized in that also comprising:
Lens are fixedly connected on the shell, are used to enlarge the sensing range of inductive means;
An inductive means is connected with control circuit board, is used to respond to the human body infrared light;
A control circuit board is installed in enclosure, is used for sending the sprinkling signal to the depositing dust atomization mechanism.
Simultaneously, shell one end is provided with the interface that is connected with atomizing de-dusting apparatus, conveniently is connected with atomizing de-dusting apparatus, and is arranged to hemispherical to lens.
Light control sensor of the present invention; Be installed in Da Xiang top, down-hole, adopt hemispherical lens can better enlarge the induction range of inductive means, inductive means adopts human body infrared light and responsive inductor thereof; As the workman through out-of-date; After inductive means perceives the human body infrared light, change the output signal, the watering of control circuit board control atomizing de-dusting apparatus; When inductive means was responded to less than the human body infrared light, then atomizing de-dusting apparatus stopped to spray.
Light control sensor of the present invention is highly sensitive, and misoperation is little, and continuous operation for a long time when depositing dust purifies air, can also reduce the concentration of pernicious gas, improves and the improvement operating environment.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
As shown in Figure 1, a kind of light control sensor is made up of the shell that hemispherical lens is installed 1,5, one inductive means that are connected with control circuit board 5 of control circuit board 4 of being installed in enclosure.Shell 1 one ends are equipped with and are used for the interface that is connected with atomizing de-dusting apparatus.
During use, be connected light-operated inductor with atomizing de-dusting apparatus, be installed on top, big tunnel, down-hole, through the inductive means induction whether the people is arranged, have the people then to stop watering, nobody is watering and lowering dust then.
Claims (3)
1. a light control sensor comprises shell, it is characterized in that also comprising:
