Control Distance

Some of the previous research builds controlled robots using devices with limited distance. The remote controlled robot controls the control distance along the rays of the sender's Infrared (IR) ray is not blocked by a 20 meters long Infrared (IR) receiver. The blue tooth controlled robot has a control distance of 40 meters. The controlled Robot Wireless Fidelity controls the maximum range of range specifications of the Access point range used. Maximum coverage ranges for outdoor access points as far as 15 Kilometers. The next   research have to do with a longer distance control than previous research. In this research is Built a robot controlled by utilizes of the Global System Mobile (GSM) communication line. This project uses two Hand phones as a sender and the other one to become receiver. Hand phone sender function is sends control signal to receiver phone. Signals sent are DTMF signals (Dual Tone Multiple Frequency). There are 9 signals control with difference function. Those functions are (1) Turn left (2) Right turn (3) Left rewind (4) Right rewind (5) Rear left (6) Rear Right (7) Stop (8) Move forward (9) Move backward. On the mobile phone receiver signal DTMF in the form of analog signal is converted by Integrated Circuit (IC) MT8870p become Signal Digital. Digital signal from IC MT 8870p is used to be input of Atmel89s52 microcontroller. Atmel89s52 output has not been able to be used for DC motor drive signal so that used transistors amplifier to control the relays. Relay as an electronic switch to connect and disconnect the DC voltage to the motor so that the DC motor can be two-way. DC motors rotating clockwise and counterclockwise. This rotation is used as a robot movement. The research results shown that 9 DTMF key tones can be used to control the robot through the GSM line. Long of distance control as far as location that is accessible GSM signal from BTS (Base Transceiver Station). Further research needs to be done to transmit video signals so that it can be done long distance visual monitor on the movement of the robot.

Robot mampu mengerjakan tugas sesuai dengan program yang dimasukkan ke dalam ‘chip’ sebagai otaknya. Secara umum, sistem kendali robot dilakukan ditempat di mana robot itu berada. Permasalahannya adalah bagaimana jika pemilik robot berada pada jarak yang jauh bahkan berbeda benua dengan robot yang dimiliki tetapi harus tetap bisa untuk mengendalikan robot tersebut. Dengan perkembangan teknologi informasi dan komunikasi menjawab tantangan long distance control system (pengendalian sistem jarak jauh), robot sebagai salah satu icon sistem otomasi tidak hanya dapat dikendalikan secara lokal tetapi mampu dikontrol jarak jauh (remote) dengan menggunakan jaringan internet. Untuk pengontrolan jarak jauh dikembangkan proyek robot yang dapat dikendalikan dari komputer (laptop / notebook) melalui jaringan internet yang diberinama ROBIN (Robot IP Network). Interface pengontrolan dilakukan melalui website untuk menggerakkan robot maju, mundur, kiri dan kanan. Web control dibuat berbasis HTML dilengkapi dengan flash dan javascript. Komunikasi wireless memanfaatkan access point yang di tempatkan pada robot. TCP/IP Starter Kit sebagai penghubung antara website dengan robot berfungsi menerjemahkan perintah yang dikirimkan oleh web untuk dieksekusi mikrokontroller. Antara robot dan pengontrol (Laptop / Notebook), masing – masing diberikan alamat identitas sehingga keduanya dapat saling berkomunikasi. ROBIN merupakan sebuah prototype robot yang pergerakannya dikontrol sebuah website melalui jaringan internet.

Ecg Interpretation

Electrocardiography (ECG) interpretation is an essential skill for physicians as well as for many other health care professionals. Continuing education is necessary to maintain these skills. The process of teaching and learning ECG interpretation is complex and involves both deductive mechanisms and recognition of patterns for different clinical situations (“pattern recognition”). The successful methodologies of interactive sessions and real time problem based learning have never been evaluated with a long distance education model. To evaluate the efficacy of broadcasting ECG rounds to different hospitals in the Southeastern Ontario region; to perform qualitative research to determine the impact of this methodology in developing and maintaining skills in ECG interpretation. ECG rounds are held weekly at Kingston General Hospital and will be transmitted live to Napanee, Belleville, Oshawa, Peterborough and Brockville. The teaching methodology is based on real ECG cases. The audience is invited to analyze the ECG case and the coordinator will introduce comments to guide the case through the proper algorithm. Final interpretation will be achieved emphasizing the deductive process and the relevance of each case. An evaluation will be filled out by each participant at the end of each session. Videoconferencing works through a vast array of internet LANs, WANs, ISDN phone lines, routers, switches, firewalls and Codecs (Coder/Decoder) and bridges. A videoconference Codec takes the analog audio and video signal codes and compresses it into a digital signal and transmits that digital signal to another Codec where the signal is decompressed and retranslated back into analog video and audio. This compression and decompression allows large amounts of data to be transferred across a network at close to real time (384 kbps with 30 frames of video per second). Videoconferencing communication works on voice activation so whichever site is speaking has the floor and is seen by all the participating sites. A continuous presence mode allows each site to have the same visual and audio involvement as the host site. A bridged multipoint can connect between 8 and 12 sites simultaneously. This innovative methodology for teaching ECG will facilitate access to developing and maintaining skills in ECG interpretation for a large number of health care providers.

The Wireless Acquisition Data System Simulator Design on Automatic Weather Monitoring Station is means of collecting, monitoring, and controlling some long distance subsystems. Automatic weather monitoring station is device for receiving data by a censor in use to gauge some weather parameters. In this Research we develop an automatic weather monitoring station design simulator by creating a subsystem in the form of prototype, using Digital Pin and Analog Pin from the microcontroller. Sensor characteristics are considered to measure several weather parameters. The principles of a system function are it will have to collect data from some subsystems to accommodate in a database, able to control and deliver instructions to the subsystem. The communication system makes the use of radio frequency by means of Frequency Shift Keying (FSK) method through Handy Talky (HT), picked out because advantages of lower power consumptions and long range of transmission. Additional advantages are, although catastrophes, data communication using HT allows to keep fast transmission. The transmission of data using HT media require a signal converter by which HT is operated by analogue signal (sound), while censor and microcontroller by digital signal and, therefore, Modulation and Demodulation techniques are necessary. The Modulation functions to convert digital signal into analogue, and just the opposite to the Demodulation, the Modulation and Demodulation processes  is using IC TCM3105. The results of the trial suggest that system design has proper functions, the communication process in this system is two-ways communication, the process was fast working in either transmitter mode or receiver mode.

Radio frequency (RF) systems in space applications are usually designed for a single task and its requirements. Flexibility is mostly limited to software-defined adaption of the signal processing in digital signal processors (DSP) or field-programmable gate arrays (FPGA). RF specifications, such as frequency band selection or RF filter bandwidth are thereby restricted to the specific application requirements. New radio frequency integrated circuit (RFIC) devices also allow the software-based reconfiguration of various RF specifications. A transfer of this RFIC technology to space systems would have a massive impact to future radio systems for space applications. The benefit of this RFIC technology allows a selection of different RF radio applications, independent of their RF parameters, to be executed on a single unit and, thus, reduces the size and weight of the whole system. Since most RF application sin space system require a high level of reliability and the RFIC is not designed for the harsh environment in space, a characterization under these special environmental conditions is mandatory. In this paper, we present the single event effect (SEE) characterization of a selected RFIC device under proton irradiation. The RFIC being tested is immune to proton induced single event latch-up and other destructive events and shows a very low response to single failure interrupts. Thus, the device is defined as a good candidate for future, highly integrated radio system in space applications.

Digital signal processing (DSP) is an area of engineering that “has seen explosive growth during the past three decades” (Mitra, 2001). Its rapid development is a result of significant advances in digital computer technology and integrated circuit fabrication (Smith, 2002; Jovanovic-Dolecek, 2002). Diniz, Silva, and Netto (2002) state that “the main advantages of digital systems relative to analog systems are high reliability, suitability for modifying the system’s characteristics, and low cost.”

Fuzzy Pid Controller

This paper presents a robust fuzzy proportional-integral-derivative (PID) controller for brushless DC motor (BLDCM) control system. The hardware circuit of the BLDCM control system is designed and implemented using a digital signal processor (DSP) TMS320LF2407A and a monolithic BLDCM controller MC33035 as the core. Furthermore, a fuzzy PID controller, which combines the advantages of good robustness of fuzzy controller and high precision of conventional PID controller, is employed in the hardware system, thereby yielding a digital, intelligent BLDCM control system. Experimental results have shown that the control system can run steadily and control accurately, and have convincingly demonstrated the usefulness of the proposed fuzzy PID controller in BLDCM control system.
