“…Both Wi-Fi and Bluetooth technologies work based on radio wave transmission, and a radio wave cannot pass through metal ( Smith & Smith, 2005 ; Hassan et al, 2016 ). In a study by Swain et al (2018) , ZigBee wireless technology sent sensed data from the underground mine to a monitoring station. In this experiment, the researchers experienced packet loss after 135 m and a sudden drop in the signal after 150 m. Path loss for transmitted data is effortless and standard in a non-line-of-sight surrounded environment.…”

Duct air quality monitoring (DAQM) is a typical process for building controls, with multiple infections outbreaks reported over time linked with duct system defilement. Various research works have been published with analyses on the air quality inside ducting systems using microcontrollers and low-cost smart sensors instead of conventional meters. However, researchers face problems sending data within limited range and cross-sections inside the duct to the gateway using available wireless technologies, as the transmission is entirely a non-line-of-sight. Therefore, this study developed a new instrument for DAQM to integrate microcontrollers and sensors with a mobile robot using LoRa as the wireless communication medium. The main contribution of this paper is the evaluation of mesh LoRa strategies using our instrument to overcome network disruption problems at the cross-sections and extend the coverage area within the duct environment. A mobile LoRa-based data collection technique is implemented for various data sensors such as DHT22, MQ7, MQ2, MQ135, and DSM50A to identify carbon monoxide, carbon dioxide, smoke, and PM2.5 levels. This study analyzed the efficiency of data transmission and signal strength to cover the air duct environment using several network topologies. The experimental design covered four different scenarios with different configurations in a multi-story building. The network performance evaluations focused on the packet delivery ratio (PDR) and the received signal strength indicator (RSSI). Experimental results in all scenarios showed an improvement in Packet Delivery Ratio (PDR) and significant improvement in the coverage area in the mesh network setup. The results conclude that the transmission efficiency and coverage area are significantly enhanced using the proposed LoRa mesh network and potentially expanded in larger duct environments.

Подземные работы на различных глубинах с транспортировкой и движущейся выработкой являются сложными по своей природе. В настоящее время в индийских рудниках наиболее часто используется проводная связь. К тому же мобильные сети не могут быть использованы из-за невозможности обеспечить покрытие. Таким образом, при управлении рудниками возникают проблемы персональной передачи данных и распределения работ. Внедрение беспроводных пейджинговых систем с применением маршрутизаторов и/или повторителей в стратегически важных местах помогает информировать рабочих, а также избежать несчастных случаев в отдаленных местах рудника. В данной статье представлена беспроводная пейджинговая система для подземных рудников, которая представляет собой двунаправленную буквенно-цифровую пейджинговую систему, использующую беспроводную сеть ZigBee и программное обеспечение пейджингового терминала. Эта система может быть использована для однонаправленной и широковещательной передачи сообщений для всех пейджеров, работающих в определенной беспроводной сети. Также разработана стратегия размещения модулей маршрутизации и прототипов пейджеров в стволе шахты и движущейся выработки на горизонтах 400 и 500 м под землей в угольных рудниках.
