A Survey on Industrial Internet With ISA100 Wireless

2020

View full text Add to dashboard Cite

We present a detailed survey of the literature on the ISA100 Wireless industrial Internet standard (also known as ISA100.11a or IEC 62734). ISA100 Wireless is the IEEE 802.15.4-compatible wireless networking standard "Wireless Systems for Industrial Automation: Process Control and Related Applications". It features technologies such as 6LoWPAN, which renders it ideal for industrial Internet edge applications. The survey focuses on the state of the art research results in the frame of ISA100 Wireless from a holistic point of view, including aspects like communication optimization, routing mechanisms, realtime control, energy management and security. Additionally, we present a set of reference works on the related deployments around the globe (experimental testbeds and real-terrain installations), as well as of the comparison to and coexistence with another highly relevant industrial standard, WirelessHART. We conclude by discussing a set of open research challenges.

Industrial wireless is a potential networking solution in many scenarios due to its flexibility and ease of communications in harsh environments. Industrial wireless in gas-sensing and air-quality monitoring applications is essential when wired communications cannot perform the task safely and effectively. A major example of such environments is confined spaces where attaching mobile gas sensors with wires is a major concern for safety and cannot be deployed in some cases. At the National Institute of Standards and Technology (NIST), we developed an end-to-end characterization method for industrial wireless networks. We employed this characterization method to study the end-to-end error and delay performance for a confined-space gas-sensing scenario. We have built the scenario using the NIST industrial wireless test bed, which includes ISA100.11a wireless devices, a channel emulator, and a high-performance programmable logic controller (PLC), where the physical process is simulated. In this work, we studied the effects of the size of the confined space, the relaying, input signal rate, and the impact of the existing workers in the confined space.

“…Therefore, it is necessary to design a wireless gas sensor that can measure NH 3 . In practical applications, there are many occasions where wireless gas sensors are needed, and the environment is usually harsh [ 8 , 9 ]. Ceramics have good mechanical properties, stable physical and chemical properties and do not easily be worn and corroded.…”

A carbon nanotube/Fe3O4 thin film-based wireless passive gas sensor with better performance is proposed. The sensitive test mechanism of LC (Inductance and capacitance resonant) wireless sensors is analyzed and the reason for choosing Fe3O4 as a gas sensing material is explained. The design and fabrication process of the sensor and the testing method are introduced. Experimental results reveal that the proposed carbon nanotube (CNT)/Fe3O4 based sensor performs well on sensing ammonia (NH3) at room temperature. The sensor exhibits not only an excellent response, good selectivity, and fast response and recovery times at room temperature, but is also characterized by good repeatability and low cost. The results for the wireless gas sensor’s performance for different NH3 gas concentrations are presented. The developed device is promising for the establishment of wireless gas sensors in harsh environments.
