Abstract Subglacial lake exploration is of great interest to the science community. RECoverable Autonomous Sonde (RECAS) provides an exploration tool to measure and sample subglacial lake environments while the subglacial lake remains isolated from the glacier surface and atmosphere. This paper presents an electronic control system design of 200 m prototype of RECAS. The proposed electronic control system consists of a surface system, a downhole control system, and a power transfer and communication system. The downhole control system is the core element of RECAS, and is responsible for sonde status monitoring, sonde motion control, subglacial water sampling and in situ analysis. A custom RS485 temperature sensor was developed to cater for the limited size and depth requirements of the system. We adopted a humidity-based measurement to monitor for a housing leak. This condition is because standard leak detection monitoring of water conductivity may be inapplicable to pure ice in Antarctica. A water sampler control board was designed to control the samplers and monitor the on/off state. A high-definition camera system with built-in storage and self-heating ability was designed to perform the video recording in the subglacial lake. The proposed electronic control system is proven effective after a series of tests.

AbstractIn this paper, we present an improved timed communication buoy system (TCBS). The system had a main float with a new mechanical design and a new electronic control system design, and described several modifications made to the autonomous communication float (ACF) of the improved TCBS. To evaluate the performance of this improved TCBS, a sea trial was conducted in the South China Sea from February to May 2015. During the sea trial, one of the ACFs was successfully released from the TCBS's main float and transmitted back the data collected by the dual acoustic Doppler current profilers (ADCPs) onboard. The preliminary data analysis for the local current conditions is also presented in this paper.

Control Failure

Current, overhaul equipments commonly used in vehicle maintenance have some disadvantages. How to design a diagnosis system easy to grasp and directly reflecting the cause of the failure has a strong value. This paper has designed a PC-based system for automotive electronic control system failure diagnosis. After the system inputs car output signal collected to the computer system, according to comparative analysis of the signal waveform by software, electronic control failure reasons can be diagnosed very conveniently.
