Abstract In recent years there has been an increasing selection of commercially available electronic components specified for very high temperature (200C+) operation, driven by the needs of harsh-environment applications such as oil and gas exploration/production, aerospace, heavy industrial, and automotive. However, there remains a significant technical challenge to integrate these components into reliable, high performance systems. We previously presented a complete reference design of a precision multichannel sensor data acquisition and control system rated to 200C, including characterized hardware, firmware, and software. The design is based around low power 16 bit SAR ADCs and an ARM® Cortex®-M0 processor and is optimized for high resolution and high throughput measurements while maintaining low power and a small footprint. In this paper we present the test results of this system over temperature. The reference platform is available off the shelf, including hardware design files, processor firmware source code, and PC software for data logging and display, providing engineers a rapid development tool for prototyping and a faster path to production for complex harsh-environment applications.

Abstract In recent years there has been an increasing selection of commercially available electronic components specified for very high temperature (200°C+) operation, driven by the needs of harsh-environment applications such as oil and gas exploration/production, aerospace, heavy industrial, and automotive. However, there remains a significant technical challenge to integrate these components into reliable, high performance systems. In this paper we present a complete reference platform implementation of a precision multichannel sensor data acquisition and control system rated to 200°C. The design offers a complete sensors-to-bits solution using a low power 16-bit, 600kSPS SAR ADC and an ARM® Cortex®-M0 based microcontroller. The signal chain is optimized for precision performance and accurate measurements while maintaining low power and a small footprint. The reference platform is available off the shelf, including hardware design files, processor firmware source code, and PC software for data logging and display, offering design engineers a rapid development tool for prototyping and a faster path to production for even complex harsh-environment applications, reducing design risk and evaluation time.

An increasing number of industries are calling for low power electronics that operate reliably at temperatures of 175°C and higher. Many of these applications require a precision data acquisition signal chain in order to digitize analog data so that it can be collected and processed. We have previously presented a new 600 kSPS SAR ADC that is rated at 210°C to meet these needs. However, the design of the supporting circuitry for a SAR ADC to achieve optimum performance is not trivial, especially over this wide temperature range. In this work we discuss the design of a complete data acquisition circuit building block that will take an analog sensor input, condition it, and digitize it to an SPI serial data stream. We will also discuss some of the practical aspects of fabricating the circuit to survive this harsh environment. This circuit reference design will be published and available off the shelf to designers of harsh environment systems.

Abstract With the rapid development of the Internet of Things and information technologies, more and more manufacturing systems become cyber-enabled, which significantly improves the flexibility and productivity of manufacturing. Furthermore, a large variety of online sensors are also commonly incorporated in the manufacturing systems for online quality monitoring and control. However, the cyber-enabled environment may pose the collected online stream sensor data under high risks of cyber-physical attacks as well. Specifically, cyber-physical attacks could occur during the manufacturing process to maliciously tamper the sensor data, which could result in false alarms or failures of anomaly detection. In addition, the cyber-physical attacks may also illegally access the collected data without authorization and cause leakage of key information. Therefore, it becomes critical to develop an effective approach to protect online stream data from these attacks so that the cyber-physical security of the manufacturing systems could be assured. To achieve this goal, an integrative blockchain-enabled method, is proposed by leveraging both asymmetry encryption and camouflage techniques. A real-world case study that protects cyber-physical security of collected stream data in additive manufacturing is provided to demonstrate the effectiveness of the proposed method. The results demonstrate that malicious tampering could be detected in a relatively short time and the risk of unauthorized data access is significantly reduced as well.

As a renewable energy source, wind energy has received more and more attention, and the wind power industry has also been advocated and developed by countries all over the world. In the production and use of wind turbines, the design and manufacturing technology of wind turbine bearings is very important. In order to ensure the reliable operation of the wind power main bearing after installation and realize the longest life of it, this paper designs a bearing test bench that can test the performance of the wind power main bearing. It can analyze the temperature, displacement, load, and moment of the key parts of the 5 MW wind power main shaft bearing. The solid modeling of the experimental platform was carried out using the 3D modeling software SolidWorks. Hydraulic loading system and test monitoring system are designed to realize the drive and control of the test bench. Through the established mathematical model, the central load of the hub is converted into the axial cylinder load and the radial cylinder load of the test bench to simulate the actual working conditions of the tested bearing. The test results show that the test bench meets various loading requirements and can reliably complete the task of testing wind power main bearings.

Abstract With the rapid development and maturity of communication technology, integrated computer technology and sensor technology, small sensors with sensing, computing and communication capabilities have begun to appear all over the world. The sensor network composed of these small sensors has received a lot of attention. This paper studies the low-power wide-area communication gateway for power data transmission. Based on the analysis of the energy consumption strategy of the power data transmission process, the low-power wide-area communication gateway for power data transmission is developed, and the developed gateway was tested. According to the peer test results of the gateway, the packet loss rate of the gateway within 100m is relatively good. Therefore, when arranging network nodes, try to control the transmission distance of the gateway within 100m. The energy consumption test shows that the energy consumption of the gateway is basically in an ideal state.

Abstract The lubricity of drilling fluid resistant to high-temperature over 200℃ is still one of the technological breakthroughs. In this study, the graphene modified with sodium dodecylbenzene sulfonate (SDBS) was selected as a resistant to high-temperature lubricant. Our results show that the drilling fluids have high stability after aging at 240°C with the assistance of the SDBS/graphene. Excitingly, the tribological performance test results revealed that the SDBS/graphene exert excellent anti-friction and anti-wear properties. Compared with the base slurry, the friction coefficient and wear rate of the SDBS/graphene slurry are reduced by 76% and 59%, respectively. The deposited film composed of graphene, Al2O3, SiO2, Fe2O3, FeSO4 actualized the protection of the sliding contact zone, proving that the sulfonate group on the SDBS/graphene contributed to prompt the deposition of the graphene and bentonite and then enhanced tribological properties of the drilling fluids. Overall, the graphene modified with SDBS is expected to solve the difficulty to form effective deposited film and poor lubricity of the drilling fluid under high-temperature.
