Bài viết này đề xuất hệ thống phun sương dập bụi tự động cho khu vực chế biến than trên cơ sở ứng dụng công nghệ IoT. Hệ thống này cho phép giám sát thời gian thực nồng độ bụi, cảnh báo khi vượt ngưỡng cho phép, tự động bật/tắt hệ thống phun sương dập bụi theo nồng độ bụi đo được nhằm đảm bảo điều kiện làm việc an toàn cho người lao động, góp phần nâng cao tuổi thọ cho máy móc, thiết bị. | Journal of Mining and Earth Sciences Vol. 63 Issue 1 2022 95 - 104 95 Building an automatic system based on IoT technology for monitoring and suppressing dust at the coal processing area Huy Duy Nguyen 1 Duong Thuy Nguyen 1 Phong Cao Khong 2 Thinh Van Nguyen 3 Trong Duc Vu 4 1 Faculty of Information Technology Hanoi University of Mining and Geology Vietnam 2 Faculty of Electromechanics Hanoi University of Mining and Geology Vietnam 3 Faculty of Mining Hanoi University of Mining and Geology Vietnam 4 Mao Khe Coal Company - Vinacomin Vietnam ARTICLE INFO ABSTRACT Article history Coal mining is one of the industries that makes many contributions to Received 8th Sep. 2021 the national economy. However this industry also has many negative Accepted 20th Dec. 2021 impacts on the environment especially in areas mining processing Available online 28th Feb. 2021 storing and transporting coal. Although coal mining companies use dust Keywords suppression methods such as the use of high pressure water jets or fixed Automatic monitoring sprinkler or misting systems. However they do not suppress dust frequently can affect to coal quality due to consume too much water. Diode rectifier Besides coal mines can not real-time monitor dust density in the air also Insulation resistive affect to the health of workers as well as reduces the life of machinery Unearthed network. and equipment. Therefore the design and implementation of an automatic coal dust suppression and monitoring system is essential for coal mining industry in Vietnam. This article proposes an automatic dust suppression system for coal processing area based on IoT technology. The system allows real-time monitoring of dust density warning when exceeding the allowable threshold automatically turning on off the mist spraying system according to the measured dust density to ensure safe working conditions for workers as well as the life of machinery and equipment increased.
