论文摘要
在本文中,我们提出了一个可靠且低延迟的远距离广泛区域(Lorawan)解决方案,以在主要事故风险(FMAR)的工厂中进行环境监测。特别是,一种用于感知工业工厂内有毒炎性气体的低功率可穿戴设备的设计目的是避免发生特殊的风险和不必要的事故。此外,检测到的数据必须紧急,可靠地传递到远程服务器,以触发预防性的即时操作,以改善机器操作。在这些情况下,由于货架设备和软件的可用性,洛万被确定为最适合需求的通信技术。因此,我们在延迟和可靠性方面评估了劳拉万的技术限制,我们提出了一种完全兼容的解决方案来克服这些限制。提出的解决方案通过使用下行链路控制数据包(DCP)设想了协调的端设备(ED)传输。实验结果验证了所提出的方法在经过考虑的FMAR方案的服务要求方面。
In this article, we propose a reliable and low-latency Long Range Wide Area Network (LoRaWAN) solution for environmental monitoring in factories at major accident risk (FMAR). In particular, a low power wearable device for sensing the toxic inflammable gases inside an industrial plant is designed with the purpose of avoiding peculiar risks and unwanted accidents to occur. Moreover, the detected data have to be urgently and reliably delivered to remote server to trigger preventive immediate actions so as to improve the machine operation. In these settings, LoRaWAN has been identified as the most proper communications technology to the needs owing to the availability of off the shelf devices and software. Hence, we assess the technological limits of LoRaWAN in terms of latency and reliability and we propose a fully LoRaWAN compliant solution to overcome these limits. The proposed solution envisages coordinated end device (ED) transmissions through the use of Downlink Control Packets (DCPs). Experimental results validate the proposed method in terms of service requirements for the considered FMAR scenario.
