Validation of Sensors has very important effects on the consequences of structural experiments and subsequent analyzing works. This article focus on the problem that if the data collected from the sensors are valid or not. It tested the validation of an target acceleration sensor on a truss structure by using Tree Augmented Naive Bayesian Classifier which is based on machine learning technology whose...
Visualization modeling based on DAQ (Data Acquisition) of SHM (Structural Health Monitoring) system helps nondestructive and Intelligent evaluation on structure. It makes up the shortage of traditional visual methods and speeds up mastering the state of structural health. It promotes the security of structure greatly. Using simulation data from the Key Laboratory of Structural Engineering and Earthquake...
This article expands the tire pressure monitoring system into the vehicle ABS controller. Based on the Matlab tool, the simulation model of the fusion system was established, and three different road conditions were simulated and analyzed. The simulation results showed that the road attachment coefficient has less effect on the tire longitudinal rigidity than the tire pressure, which is necessary...
In recent years, greenhouse technology in agriculture is to automation, information technology direction with the IOT (internet of things) technology rapid development and wide application. In the paper, control networks and information networks integration of IOT technology has been studied based on the actual situation of agricultural production. Remote monitoring system with internet and wireless...
A low cost, fast and convenient method based on electronic nose for determination of ammonia nitrogen in wastewater is developed in this study. The pH of the sample is adjusted to higher than 11 by adding saturated sodium hydroxide solution, through which most of the ammonium ions transform into ammonia and volatilize to the gas phase following Henry's law. A sensor array consist of four metal oxide...
This paper introduces a portable ECG monitor with USB host Interface. This system uses Microprocessor C8051F021 as its controlling core, and SL811HS as USB host Interface chip. Based on this hardware, the paper presents USB host specification stack, specification frame about USB Mass Storage and FAT file system so that the collected ECG signals can be stored in U-Disk without delay. In addition, the...
People have the need to use a novel consumer clock device for home automation, personal security and convenience. This paper presents the design and implementation of the innovative system. The system architecture which is controlled by micro-controller unit (MCU) includes main alarm clock module, lucky module and security module. In the main alarm clock module, we create a novel hourglass clock model...
The design of multi-parameter physiological monitor based on CAN bus is presented. This article describes the design of the hardware and software in the monitor. The monitor with CAN bus receives the physiological parameters which are detected by Cygnal MCU and display the parameters through GUI in ARM/Linux system. This method implements the long transmission of the data and the plug and play of...
Metal oxide arresters (MOAs) are widely used on HV transmission lines for over-voltage protection. However, it is still difficult to carry out its on-line monitoring, because of some bottlenecks such as the installation of sensor, signal transmission and on-site power supply, et al. This paper first discusses the improved acquisition sensor for getting leakage current value and recording the number...
