Automatic dust-fall spray control system for tunnel, and control method thereof

Abstract

The invention discloses an automatic dust-fall spray control system for a tunnel, and a control method thereof. The system is composed of a dust sensor, a data processor, a control host, a cloud monitoring system and a water spraying device; through arrangement of a dust monitor in a tunnel operation area, a signal is transmitted to a control center and the cloud monitoring system; dust concentration warning values of at least two different levels are preset; when the dust concentration of a monitoring site reaches or exceeds the warning values of different levels set through the dust sensor,a solenoid valve of the water spraying device is controlled to open for spraying water to a workplace for dust fall; and through control over different opening degrees of the solenoid valve and different water flow rates corresponding to the warning values of different levels, dust of the workplace is reduced. According to the control system, through setting of multilevel warning thresholds, harmsare restrained at the embryonic stage; the system is improved through the process that the signal is transmitted to a water valve, and the purpose that different warning values correspond to different flow and flow rates for dust fall is achieved; and resources are saved, and targeted dust fall is performed.

Description

technical field [0001] The invention belongs to the technical field of environmental protection construction, and relates to a spray dust control technology used in engineering construction, in particular to a tunnel automatic dust control spray control system and a control method thereof. Background technique [0002] The existence of dust has a catastrophic impact on the environment, and its harm is mainly manifested in three aspects: First, it pollutes the environment and endangers human health. After long-term inhalation of dust, mild cases will suffer from respiratory inflammation and skin diseases, and severe cases will suffer from pneumoconiosis; the second is to accelerate mechanical wear and shorten the service life of precision equipment. With the improvement of mechanization, electrification, and automation, the impact of dust on equipment performance and service life will become more and more prominent; the third is to reduce the visibility of the working environ...
