Item type:Publication, Wireless Carbon Monoxide Level Control and Monitoring SystemThis paper proposes an online carbon monoxide control and monitoring system. The proposed system comprises an MQ-7 CO gas sensor module, a DHT11 digital temperature and humidity sensor module, an ESP8266 module, and a Relay Module. The ThingSpeak platform is used to create HMI for online monitoring of CO level, temperature, humidity, and status of the ventilation fan. This proposed system can measure CO and monitor all parameters of measurement data, alert users when CO values exceed the set value. In addition, the measured CO values are used to control the ventilation system operation (ON or OFF) to maintain the CO at a non-harmful level. The experiment testing and results with three conditions show that the proposed system can measure and monitor CO level, temperature, and humidity online with satisfying values. The ventilation fan can operate with function as a design procedure and maintain CO at a non-harmful level. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Experimental Verification of Wind Power Generation System Using Diode Bridge Rectifier Circuit with Wind Turbine Simulator(2022-01-01); ; Ohyama, Kazuhiro– This paper presents Wind Power Generation System using Diode Bridge Rectifier (WPGS-DBR method). Experimental results have been obtained by Wind Turbine Simulator (WTS). The WTS emulates wind turbine behavior using a servo motor as a drive system. Mechanical torque references used to drive the motor are calculated using wind turbine data such as wing blade, wind velocity, and wind turbine rotation speed. DBR method has three-mode control for three ranges of wind speed: low, medium, and high, respectively. In low and medium mode, the control system adjusts the armature current of a generator and DC link voltage with a Vector-Controlled Inverter (VCI) to control wind turbine speed. In high mode, the control system modulates the pitch angle of the wind turbine using a pitch angle control system for controlling wind turbine rotational speed. The DBR simplifies the maintenance of WPGS while improving reliability. In addition, the DBR method costs less compared with the WPGS using a PWM converter. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Emulation Technique for Wind Turbines Using Servo Motor and Induction Motor(2024-01-01); ; This paper proposes the emulation technique for wind turbines using two types of motor, servo motor, and induction motor. The focus is on simulating the work process of wind turbines at multi-wind velocity to test the capacity and efficiency of generating three-phase electricity. The wind turbine emulator was created by using a program and mechanical parts. The goal of this emulator is to check the efficiency of wind turbine blades at different wind speeds and to test the accuracy of the simulation method by using a different motor. The first emulator uses a 400-Watt synchronous generator from a wind turbine connected to a 400-Watt servo motor controlled by a servo amplifier. The second emulator uses a 400-Watt synchronous generator from a similar wind turbine connected to a 400-watt induction motor installed with an encoder controlled by an inverter. Motor torque is calculated by using mathematic equations from the LabVIEW program, and the data of the wind turbine blade is simulated by using the ANSYS program. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Resistive-Sensor Interfacing Circuit for Remote Measurement Using CFOA(2024-01-01); ; ; Kaewpoonsuk, AnuchaAn alternative approach to implementing an interfacing circuit for resistive sensor-based remote measurement is presented. The proposed technique uses a Current Feedback Operational Amplifier (CFOA) as an active building block to produce an output voltage linearly related to the resistance of the sensor. Moreover, the accuracy of the output voltage is improved by the enhancement of CFOA. In addition, the proposed circuit provides compensation for the effects of lead-wire resistance. The performance of the proposed technique is discussed in detail and confirmed by PSPICE program simulation and experimental implementation. The resistance decade box is used in the experiment. The maximum error on the output voltage of the experimental results is about 0.4234 %. The experimental results show that the proposed technique provides good performance. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Bitmap picture to toolpaths converter for NC machineA simple method to create the toolpaths from bitmap picture of the workpiece for NC machine is described in this article. Halftone process is used to reproduce a continuous tone picture to binary tone picture for making a prototype picture. The obtained two dimensions picture with halftone process is employed to create the toolpaths of the sample workpiece. The workpiece dimension can be scaled to limitation of work table of NC machine by user with independent of picture resolution. The toolpaths are created as cutter location data (CL) that can be imported to postprocessor for NC machine. The proposed method is developed using visual C# programming language under window environment. Experimental implementation exhibits that the proposed bitmap picture to toolpath converter is efficient for the postprocessor to generate machine command for sculpture the workpiece from bitmap picture. ©ICROS.
