Carpentry-house working clothes control method capable of early warning

Abstract

The invention provides a carpentry-house working clothes control method capable of early warning. The method comprises that critical values A1 and A2 of a switching signal output unit in a comparisoncircuit are set; three work states of a working clothes early warning system are set; an electric signal is formed during measurement of a dust electrode sensor unit, the magnitude of the electric signal is in direction proportion to the dust quality content, and the electric signal is further amplified via a transmitter unit; when a current value after operation of the transmitter unit is lower than A1, the switching signal output unit of the comparison circuit outputs no signal to a controller, and neither an air circular nor a buzzing alarm works; when the current value after operation is greater than or equivalent to A1 and lower than A2, the switching signal output unit of the comparison circuit outputs the signal to the controller, and the air circulator works; and when the current value after operation is greater than or equivalent to A2, the buzzing alarm works. According to the control method, the structure is simple, the performance is stable, hidden safety hazards of a carpentry house can be reduced, and the health of workers is ensured.

Description

【Technical field】 [0001] The invention relates to a control method for carpentry work clothes with early warning function. 【Background technique】 [0002] In the woodworking process, cutting, processing, and grinding are the main processes. Wood dust is produced during this process, which can lead to statutory occupational diseases and, in severe cases, dust explosions. In the online monitoring of dust or the monitoring of occupational hazard factors, fixed-point sampling is often used. During the sampling process, the sampling points and sampling periods cannot truly reflect the dust concentration due to the complexity of the processing procedures and woodworking conditions, and it is these distorted detection values ​​that provide decisive operation adjustment for the ventilation and dust removal system and the explosion-proof system. According to the basis, this brings huge hidden dangers to the health and life safety of workers. Therefore, there is a need for a techni...
