Abstract
The invention belongs to the field of sensors, and particularly relates to a voice operated sensor comprising a housing, an induction component and a control circuit board, wherein the housing is connected with the interface of a spray dust-settling device; the induction component is connected with the control circuit board; and the control circuit board is mounted in the housing. The voice operated sensor provided by the invention has the advantages that the sensitivity is high; the misoperation is less; long-term continuous operation is realized; and the concentration of harmful gas can be reduced while the dust-settling is carried out for air purification, which improves and controls working environment.
Description
Technical field
The invention belongs to sensor field, relate in particular to a kind of coal mine evacuation working face acoustic control sensor that atomizing de-dusting apparatus uses when blowing out.
Background technology
Along with greatly developing of colliery, people recognize the harm of dust gradually, and 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, and dust also can cause damage to the workman is healthy simultaneously.
When especially coal mine evacuation working face is blown out, can produce amounts of dust, use atomizing de-dusting apparatus to carry out depositing dust usually to this problem people and handle; But all need Artificial Control; Flexibility ratio is low, can not realize the automation of spraying preventing that to people the down-hole dust from having caused inconvenience.
Summary of the invention
The problem that atomizing de-dusting apparatus can not spray depositing dust flexibly when blowing out for solving coal mine evacuation working face; The present invention provides a kind of acoustic control sensor; Can control atomizing de-dusting apparatus through induction sound size and carry out spraying operation; Improve the sprinkling flexibility, practiced thrift cost of labor, realized automation.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of acoustic control sensor, comprise shell, and it is characterized in that also comprising:
An inductive means is connected with control circuit board, is used to respond to sound;
A control circuit board is installed in enclosure, is used for sending the sprinkling signal to the depositing dust atomization mechanism.
Described shell one end is provided with the interface that is connected with atomizing de-dusting apparatus.Described inductive means sends level signal when sensing the sound that is not less than 115dB.
Acoustic control sensor of the present invention; Be installed near the driving face of down-hole;, send acoustic control sensor sensing parts level signal when sensing the sound that is not less than 115dB, the watering of control circuit board control atomizing de-dusting apparatus, and inductive means only sends signal when induction is not less than the sound of 115dB; Can effectively filter out sound, the impact sound of hammer and people's Conversation Voice that coal-winning machine produces, thereby realize the only purpose of sprinkling when driving face is blown out.
Acoustic control transducer sensitivity of the present invention is high, and misoperation is little.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 acoustic control sensor is made up of shell 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 the acoustic control inductor with atomizing de-dusting apparatus, be installed near the development end of down-hole, the sound when blowing out through inductive means induction development end is controlled the sprinkling depositing dust of atomizing de-dusting apparatus.
