System Overview
The dust concentration in the roadway air flow is detected by a dust concentration sensor. When the measured value exceeds the specified value, a signal is sent to the sub-control box to control the electric valve and turn on the spray device, realizing the automatic spray function when the dust concentration exceeds the limit. When there are personnel walking in the roadway, the infrared pyroelectric sensor can detect and send a signal to control the start and stop of the spray device during the personnel’s passage.
The roadway dust suppression can be used as an independent system or connected to the centralized control software platform, enabling on-site display of dust concentration, online monitoring and real-time data upload. The ground software can monitor the dust concentration and the spray status of the dust suppression system in real time, and the start/stop of the spray in the dust suppression system can also be remotely controlled from the ground upper computer, realizing the function of remote centralized control.

System Composition
The roadway dust suppression is mainly composed of a dust concentration sensor, a sub-control box, a spray device, an infrared pyroelectric sensor, etc.

System Features
(1) Automatic spray when dust concentration exceeds the limit, with real-time monitoring and dust suppression on demand;
(2) Automatic spray stop when people or vehicles pass by, ensuring traffic safety and comfort;
(3) Supports networking, remote monitoring of start/stop, and convenient centralized management.
