Item type:Publication, Identity checking system by visible light(2014-01-01); ; Dumrong, JirattawutA new identity checking system by visible light can fulfill some limitations of QRCode and RFID technology wherewith this system can check further distance. This paper is a model to be applied to other areas. In this system, the communication between LED Blinking and camera consists of transmitter and receiver. Transmitter is a microcontroller to control LED for blinking pattern one pattern for one identity of object and save in database. Receiver consists of camera to detect LED blinking by image processing. When detecting LED blinking receive code for identity of object then get code to check identity with database. This system can be applied to various such as security, advertising, identify system, and etc. © 2014 IEEE. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Implementation of ECG portable device for real-time signal monitoring(2017-11-24); ; ; Aoyama, H.In this paper presents a system for heart rate signal analysis in ECG (Electrocardiography) format using STM32f7 board. Electrode is used for recording the signal with stick on body in lead 2 orientations. Signal processing method are used upper average, slope and interval checking algorithm to process ECG signal in real-time. In experiment, to acquire a frequency of heart beat and display ECG signal and heart rate on STM32f7 board compare with wearable device that result have error rate less than 1%. This system is portable to use and sufficient battery for recording signal to analyze and monitor throughout the day. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Low pass filters based on bernstein-balazs operators(2017-11-24); ; ; Janchitrapongvej, K.This paper presents a design of low-pass filter by using Bernstein-Balazs operators. It has more parameters than classical Bernstein polynomials. The parameters and can adjust maximally flat, slope of linear phase and constant of delay. In the results, the proposed method shows the magnitude response has maximally flat, linear with non-minimum phase and nearly constant delay. The example of applications of this proposed method is desired to design the gain equalizer at -1dB and confirm the stability of the approximated transfer function by Mihailov’s criterion. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, On development of train control and signaling simulation(2016-01-24); Vijittanasan, AlongkonThe increasing of transportation demand in Thailand requires a lot of human resources to support the future railway system. Therefore, we have developed an in-house fixed-block train control simulation system to be used as a tool for helping learners to understand train control procedures. The train control simulation system combines of train model, signaling control hardware, and controlling and signaling simulation software. ROCO train models and switches are controlled by the z21 controller box which are in-turn commanded by controlling and signaling simulation software through Wi-Fi. The train control software gets train position from RFID reader that installed on train model to read RFID tags under the rail. The software can control train model movement respecting to the defined timetable. Leaner able to reserve a route, the software will check for the availability of tracks and switches throughout the route and then reserve and set the status of the corresponding switches to the correct positions in order to ensure the route safety.
