A novel Ethernet based processing system for remote source harmonic detectionTELKOMNIKA JOURNAL
This work is carried out to objectively establish a new method to detect harmonics and measure the total harmonic distortion (THD) in a remote source, such as a high voltage transformer. The proposed approach utilized embedded design techniques to construct an embedded processor system with Ethernet intellectual property core to acquire data from a remote harmonics source. The designed system has several notable merits, namely, it is portable that can be applied in the work field, and it avoids workers from being subject to a hazard high voltage shock as well as its simplicity and high accuracy. The harmonics detection and analysis are achieved by inserting a microcontroller system near the high voltage transformer to acquire the necessary data and transmit it to a remote embedded processor system that is used to detect and analyze the harmonics. The microcontroller and the processor systems are connected by a wide-area network (WAN) through Ethernet and transmission control protocol/internet protocol (TCP/IP) protocols. The processor system is accommodated to perform 128 points fast Fourier transform for harmonics detection. Matlab simulations are used to validate the results. It is found that the results match very accurately the simulation results with an error of less than 0.02%.
Influences of Buffer Size and Eb/No on Very Small Aperture Terminal (VSAT) Co...TELKOMNIKA JOURNAL
In data communication of the signal transmitted from the transmitter (Tx) to receiver (Rx) stations
is very influential. Buffer and Eb/No are two parameters that influence the quality of signal. This research
measures those parameters and the relationship among them. This research employs data collected on
the Link STM-1 side in Makassar and Timika operated by PT. Telkom Metra Bogor. The period of data is
carried out for 56 days taken by using Simple Management Network Protocol (SNMP). To analyze the
relationship among those two parameters, we use product moment correlation (PMC) method. The result
correlation of the data buffer and Eb/No with a level of real is 0.05 and then buffer set in modem CDM 700
is 50% with threshold Eb/No 12.1 dB and the modulations used 64-QAM. That resulted correlation of side in
Makassar is 0.648 and the p-value is 0.000. Correlation of side in Timika is 0.722 and the p-value is 0.000.
These results suggest that the two parameters are correlated strong and significant.
Energy scavenging using vibrations from bluetooth controlled DC motorTELKOMNIKA JOURNAL
Wide spectrum of research for application-based solutions has grown due to the requirement of automation of general electrical appliances. A low-cost solution is presented in this paper to control DC motor using Bluetooth module and controlled by an ARM processor. The main objective here is to build an efficient closed loop system which is wirelessly controlled by ARM processor 2103 using Bluetooth module and Bluetooth dongle. The system suggested here is expandable and can be integrated with latest technologies as well. The paper gives the details of the prototype for home automation system and gives the expected results with 0.1% tolerance. It also suggests the ways to integrate this system with the mobile phones and hence control the devices with the mobile handsets. The vibration frequency of the DC motor is used to generate electrical potential using MEMS tecnonlogy. A novel idea of self powered DC motor is thus presented by installing MEMS based energy harvester on the motor shaft.
The paper introduces a system by which we are capable of controlling the usage of electricity to a greater extent. In this system the customer is able to know about the per day consumption of electricity. It also informs the user if any intruder breaks in or about gas leakage while the user is away from the household. In this, we use PIC 16F877A microcontroller, in order to calculate the per day consumption, also a relay network is used to control the appliances/devices connected to it. The presence of intruder and gas leakage is noted with the help of sensors attached with the module. The module as a whole performs automation of home.
- This paper shows an approach for designing a
system which implement a microcontroller-based control module
that receives its instructions and commands from a cellular phone
over the GSM (Global system for mobile communication)
network. The microcontroller then will carry out the issued
commands and then communicate the status of a given appliance
or device back to the cellular phone.This device allows a user to
remotely control and monitor multiple home/office appliances
using a cellular phone. This system will be a powerful and flexible
tool that will offer this service at any time, and from anywhere
that has network coverage. Due to the fact that the combination
and sequential logic circuits have more components soldered
together, inflexible, more difficult to the user, and not
programmable, the 8951 micro controller was chosen because it
can be written to and read from and also has an internal memory
which makes it to be versatile in application and user
friendly. Apart from the micro controller, other electrical /
electronic components used include: resistors, filters, voltage
regulator, transformer, rectifiers, capacitors, DTMF (Dual Tone
Multi Frequency) Integrated circuit etc.
An electric circuits' remote switching system based on gsm radio networkeSAT Journals
Abstract Mobile phone industry is classified among the fastest growing engineering branches. It has to be exploited for vast applications, reliability and affordability. Mobile cellular phone subscribers have reached saturation point; with such information, the basic cell phone that was mainly utilized to make calls will also be utilized for remote switching and control activities. The now developed system is based on the global system for mobile communications (GSM) radio network: it will operate as a very long distance remote switch. Utilizing the daily cell phone, a user will either put on/off any desired electric circuit located in an owned, controlled compound. Two cell phones are provided, one being a mobile transmitter user end and another being referred to as a fixed receiver end. A signal will be sent from the user end to put a consumer’s electric circuit either on or off at the receiver end; afterwards, the receiver end will notify the user-end about the on/off state of the consumer. The particularity of this publication is the system simplicity, yet cheap and safe, so that even very low income cell phone users can enjoy radio frequency (RF) technology’s increasing applications. The software utilized to develop and simulate circuits is the linear technology, LT spice. The calculative theory has quantitatively enriched the methodology. Both the building blocks and the physical implementation diagrams for the system are herein contained. The remote switching system based on GSM radio network has been successfully designed, implemented, tested and its functionality has been examined.

method was performed through a series of simulations. The numerical results showed the effectiveness of
the proposed control method in controlling the spacecraft attitude in the presence of external disturbances.

Review on Islanding Detection Methods for Photovoltaic InverterNooria Sukmaningtyas
Solar power generation, which is regarded as an ideal environment-friendly manner for power
generation, is getting more and more attention. When photovoltaic inverter is connected to the grid, the
island effect is a special problem to confront. This paper briefly analyzes the island effects and makes a
summary of both domestic and external research progress concerning islanding detection methods; the
islanding detection methods can be divided into two classes: one is grid-side detection; the other is local
detection. The local detection is generally divided into passive methods and active methods. The theory of
advantages and disadvantages of those methods are briefly introduced in this paper. At the end of the
paper, to deal with the disadvantages of those methods that are mentioned, it proposes the research
direction for deeper study of islanding detection methods.
Stabilizing Planar Inverted Pendulum System Based on Fuzzy Nine-point ControllerNooria Sukmaningtyas
In order to stabilize planar inverted pendulum, after analyzing the physical characteristics of the
planar inverted pendulum system, a pendulum nine-point controller and a car nine-point controller for Xaxis
and Y-axis were designed respectively. Then a fuzzy coordinator was designed using the fuzzy
control theory based on the priority of those two controllers, and the priority level of the pendulum is higher
than the car. Thus, the control tasks of each controller in each axis were harmonized successfully. The
designed control strategy did not depend on mathematical model of the system; it depended on the control
experience of people or the control experts. The compared experiments showed that the control strategy
was easy and effective, what was’s more; it had a very good robust feature.
Gross Error Elimination Based on the Polynomial Least Square Method in Integr...Nooria Sukmaningtyas
The measurement data of parameter in the electrical equipment contains many noises in subway
integrated monitoring system. To eliminate the impact of gross error in the measurement data, a
polynomial least square curve fitting algorithm is used in this paper. Based on the Rajda criterion, the
algorithm gives the variance estimation of the noises, and then uses dynamic threshold to detect and
replace the measurement data with gross error by statistical estimation. Finally, a data processing
procedure has been presented to deal with the gross error. The practical application indicates that the
proposed algorithm can effectively eliminate the gross error in many types of measurement signals so as
to ensure the reliability of the monitoring system.

INS/GPS integrated navigation system is studied in this paper for the hypersonic UAV in order to
satisfy the precise guidance requirements of hypersonic UAV and in response to the defects while the
inertial navigation system (INS) and the global positioning system (GPS) are being applied separately. The
information of UAV including position, velocity and attitude can be obtained by using INS and GPS
respectively after generating a reference trajectory. The corresponding errors of two navigation systems
can be obtained through comparing the navigation information of the above two guidance systems.
Kalman filter is designed to estimate the navigation errors and then the navigation information of INS are
corrected. The non-equivalence relationship between the platform misalignment angle and attitude error
angle are considered so that the navigation accuracy is further improved. The Simulink simulation results
show that INS/GPS integrated navigation system can help to achieve higher accuracy and better antiinterference
ability than INS navigation system and this system can also satisfy the navigation accuracy
requirements of hypersonic UAV.
Research on Space Target Recognition Algorithm Based on Empirical Mode Decomp...Nooria Sukmaningtyas
The space target recognition algorithm, which is based on the time series of radar cross section
(RCS), is proposed in this paper to solve the problems of space target recognition in the active radar
system. In the algorithm, EMD method is applied for the first time to extract the eigen of RCS time series.
The normalized instantaneous frequencies of high-frequency intrinsic mode functions obtained by EMD are
used as the eigen values for the recognition, and an effective target recognition criterion is established.
The effectiveness and the stability of the algorithm are verified by both simulation data and real data. In
addition, the algorithm could reduce the estimation bias of RCS caused by inaccurate evaluation, and it is
of great significance in promoting the target recognition ability of narrow-band radar in practice.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

focuses on the implement of monitoring terminal in following text.
Figure 1. Overall architecture of the monitoring system
3. Design of the Monitoring Terminal
The monitoring terminal consists of microcontrollers, sensors, the circuit of MF RC500
and a GSM module. Once the abnormal parameter data appear, processor will arrange the
abnormal message, initiate the data transmission and then send them out to control center [2].
Microcontroller module is W77E58, which is used as a master chip. The W77E58 is a fast 8051
compatible microcontroller with a redesigned processor core for no waste of clock and memory
cycles. As a result, the execution of 8051 instruction is faster than the original 8051 at the same
crystal speed. Typically, the instruction execution time of W77E58 is 1.5 to 3 times faster then
that of traditional 8051. Also, the W77E58 contains 32 KB Flash EPROM, two enhanced serial
ports and provides operation voltage from 4.5V to 5.5V [3].

The value of parameters is measured in the system including air temperature, air
humidity and information of entrance guard etc. The sensors and MFRC500 are combined to
collect the real-time environment parameter data and hand over these data to microcontroller
processor for further handling and storage. The microcontroller determines whether the data are
normal or not. Once the abnormal parameter data appear, processor will arrange the abnormal
message, initiate the data transmission, and then send them out to control center. C51
language is adopted according to the features of data and C language for system development.
Software design mainly includes three parts: collecting and displaying temperature and humidity
of base stations, reading and decoding short messages, encoding and sending temperature and
humidity. The block diagram of the monitoring terminal is shown as in Figure 2.
3.1. Sensor Design
SHT10 is Sensirion’s family of surface mountable relative humidity and temperature
sensors. The sensor integrates sensor elements plus signals processing on a tiny foot and
provides a fully calibrated digital output. A unique capacitive sensor element is used for
measuring relative humidity while temperature is measured by a band-gap sensor. The sensor
is seamlessly coupled to a 14bit analog to digital converter and a serial interface circuit. This
results in superior signal quality, a fast response and insensitivity to external disturbances
(EMC). A unique capacitive sensor element is used for measuring relative humidity while
temperature is measured by a band-gap sensor [4]. It has output of standardized digital signal,
small size and low power consumption. This sensor can measure in the range of -40-123.8℃
and 0%-100% relative humidity. Under the conditions of 25℃ and 3.3V, the relative humidity
accuracy can reach ±4.5%R.H., while temperature accuracy is ±0.5℃.
In the paper the measurement resolution of is 14 bit for temperature and 12 bit for
humidity. Because of nonlinear relation between digital output and relative humidity (RH) for the
sensor SHT10, the data from SHT10 must be processed before being converted to actual
physical quantity. For compensating non-linearity of the humidity sensor, it is recommended to
convert the humidity readout (SORH) with the following formula [4]:
RHlinear=c1+c2*SORH+c3*SORH

The values of humidity coefficients are given in Table 1:
Table 1. SHT10 humidity conversion coefficients
SQRH C1 C2 C3
12bit -4.000 0.0405 -2.8000E-6
In case of temperature, the following formula is used to convert digital readout (SOT) to
temperature value [4]:
T=d1+d2*SOT (2)
The values of temperature coefficients are given in Table 2:

RH value is calculated at 25℃ in the formula (1), but actual test temperature is variable
in a certain range. Therefore the temperature coefficient is considered for the sensor SHT10
according to the following formula [4], namely, coefficients for the temperature compensation
are given in Table 3.
RHtrue=(T-25)*(t1+t2*SORH)+RHlinear (3)
The values of temperature compensation coefficients are given in table3. The flow
diagram of SHT10 software design is shown in Figure 3. Temperature and humidity are
calculated with the following programs:

MFRC500 is a member of a new family with highly integrated reader ICs for contactless
communication on 13.56MHz which supports all protocol layers of the ISO 14443A [5]. The
paper gives a solution of design and implementation for RFID R/W device based on the key
character and internal structure of MF RC500 chip, the R/W operating to Mifare1 card is
processed by the control and communication between P89C51 and MF RC500. The aim is to
provide the required understanding of the MIFARE RF interface (ISO 14443A) to design
application specific antennas and matching circuits to achieve the best performance for a
communication with a contactless MIFARE card [6]. Receiving circuitry and EMC filter are as
shown in Figure 4 [7]. As well as antenna circuit shown in Figure 5 [8]. The flow diagram of read

3.3. Circuit of GSM Terminal
Sony Ericsson GR47 is selected which belong to a new generation of Sony Ericsson
Mobile Communication GSM/GPRS modules. The GR47 module provides Chinese language,
and provides four transmission modes including voice, data, short message, and FAX. The
module works in frequency bands EGSM 900/1800 MHz, power voltage 3.3-3.5V [9]. The
product can be used in machine-to-machine applications and man-to-machine applications
where there is a need to send and receive data (by SMS,CSD, HSCSD, or GPRS), and make
voice calls by the GSM network [9].
Microcontroller presents a pulse to the ON/OFF signal connection of GR47, which is
designed to exceed 0.5 seconds but less than 1.0 second [8]. When SM is prepared to be sent,
the microcontroller sends AT commands to the radio device via serial interface ports. The
digram of GR47 design is as shown in Figure 7. In order to reduce electrical current, R1 and
R2(R1=R2=3.6kΩ) are used. (R3=3.6kΩ, R4=12kΩ) [10].
Figure 7. The diagram of the GR47 and W77E58
At present, there are two usual modes: Text and PDU (Protocol Data Unit). It is easy
and simple to receive and send for Text mode, but Chinese short message cannot be received
and sent. However these can be realized for PDU mode which includes three codes: 7-bit, 8-bit
and UCS2. Among these codes, ordinary ASCII characters are sent for 7-bit code, data
information for 8-bit code, Unicode characters for UCS2 code. In this paper, PDU mode is
adopted, whose data frame structure is as in Table.4.
Table 4. PDU data package structure
SMSC PDU type MR DA DIP DCS VP UDL UD
In PDU data frame structure, SMSC field stands for short message center address; as
well as PDU type for data package type, MR data package for sent information, DA for
destination address, DIP for protocol identifier and DCS for short message code mode. Code of
digit or character is ‘00’, and code of Chinese is ‘08’ for Unicode adopted in this paper. VP
stands for valid time of short message as well as UDL for the length of data and UD for the
content of specific short message [11].

4. Implementation and Results
The realizations of proposed system functions rely on mobile communication between
computer and microcontroller based on GSM. The system comprises a control center composed
of a server, a GSM module and a database system, and monitoring terminal composed of
microcontrollers, sensors, a MF RC500 and a GSM module in the base station. The value of
parameters is measured at every base station, including air temperature, air humidity, the
information of entrance guard etc. The sensors and MFRC500 are combined to collect the real-
time environment parameter data and hand over these data to microcontroller processor for
handling and storage.The microcontroller determines whether the data are normal or not. Once
the abnormal parameter data appear, processor will arrange the abnormal message and initiate
the data transmission and send it out to control center. The flow diagram of the monitor terminal
is shown in Figure 8.

5. Conclusion
This paper proposes a remote monitoring system base on SM. The most significant
features of the system are applications of RF and GSM technology. The results show that it can
meet the basic requirements of sensor accuracy, communication and so on. In addition, the
system has good extensibility and compatibility. The operation and implementation cost of the
system has been reduced by the use of SMS. Besides, it is easy to install and upgrade. For
example, when the number of monitoring information increases, the communication mode of
system can be designed based on GPRS. Because the GR47 module can support GRPS, the
hardware of system does not need to change. There are wide application prospects because of
limitlessness of terrain and being suitable for remote monitor.
