The interface device for communicating (IDC) as a bridge for the merger between two different systems based on different protocols and standards can be made of several electronic modules. The two Arduino boards (UNO R3 and MEGA2560 R3) have been constructed as the electronic modules of a gateway become a haft-duplex IDC, and are driven by the touch-tone signal. The research objectives, i.e., assembling some of the hardware for the embodiment of the adapter system, making a program structure, and performing a test of the IDC system. The haft-duplex IDC has been carried out by integrating all components by wiring to form an embedded system. Then, programming the microcontroller modules based on the Arduino software is carried outin six stages. Finally, the simulation test with the provision of conditions is carried out and obtained of six conditions for (i) the circuit of ring detection, (ii) the circuit of voice-operated transmit, (iii) the circuit off/on the hook of the telephone module, (iv) the circuit of tone decoder, (v) dial-up telephone numbers via push buttons and switching IC circuits, and (vi) the circuits of voice recording and storage in the form to playback. The test's success with six conditions has been an indication that the microcontroller-based IDC system is functioning as expected. Completing, the conclusion, and recommendationsrelated to measurement on the various purposes and the real conditions for the half-duplex interface adapter can be implemented.
The prototype of the electronic system aided personal computer for monitoring the condition of the electric power supply have been done. The principle for fabricating the prototype of the electronic system based on the mechanism of handshaking system between electronic systems and line port for a printer. Program embedded on a personal computer with certain specifications for the operation of the system. The prototype of the electronic system consists of 3 (three) main subsystems, namely the diver circuit, sensor circuit, and the circuit of electrical installations analogy. Measuring against the prototype performance is carried out on the port line for the printer, driver circuit, sensor circuit, and electrical installation analogy circuit. The path performance on the port line for the printer is focused on high or low logic on each port. Data port condition is used to process data transmission, while the status and control port conditions are used to process data reception. The performance of the control circuit is very much determined by inputting data from the user so that it is closely related to the data port. The performance of the sensor circuit is very much determined by the condition of the electrical installation analogy, so it is closely related to the status and control ports. The performance of the circuit of electrical installation analogy is marked by the presence of a voltage value, and if the voltage measured in the electrical installation is 220 volts AC, then it is as an installation marker inactive condition. Overall the system is capable of 8 remote monitoring points so that the condition of the electrical power supply through the electrical panel can be monitored at any time.
A miniature sorting of material quality has been made, aided by a prototype of the controller system based on the Mitsubishi FX1N-24MR Programmable Logic Controller (PLC). A number of stages include the manufacture of the conveyor system unit, the electrical system, PLC programming, and performance measurement. The conveyor unit assembling was processed by installing the conveyor belt, dc motor, pneumatic cylinder, solenoid valve, and sensors. The electrical system is an integration of the Mitsubishi FX1N-24MR PLC, switched-mode power supply, miniature circuit breaker (MCB), dc voltage regulator circuit, relays, digital counters, pushbuttons, and selector switches arranged in a 20 x 30 x 15 cm panel box. Mitsubishi PLC system programming is based on algorithmic determination and ladder diagram arrangement assisted by GX Developer (GX Work). Performance measurement in the form of pulse readings is carried out by setting and manufacturing ladder counters and shift registers to count the number of pulses for each material and the accuracy of sorting when the material is detected simultaneously. The system performance is indicated by pulse reading accuracy and sorting timing accuracy. The reading of the pulse from the proximity switch affects the counter calculation to activate the pneumatic cylinder unit in sorting. Sorting for material-A takes 11 pulses, while for material-B, it takes 19 pulses. The synchronization measurement functions when an error occurs in the system in order to maintain the input received is the same as the output in the PLC-based control system.
An electronic device with various purposes needs in-depth study from the very beginning of the idea, before getting the final product. It relates to an essential role in providing user's infrastructure and service. The research objectives are to obtain the electronic circuits, modules, and devices by integrating the wiring. The research methods are conducted in the form of designing, manufacturing, assembling, and diagnosing. Designing stage is to obtain several electronic circuits as a liaison and the manufacturing stage to obtain the printed circuit board. The assembling stage is to obtain the gateway boards which controlled by the Arduino modules and diagnosing stage to obtain the interface device for communicating (IDC) is formed by integrating the wiring. Integrating several electronic circuits, modules, and devices have resulted in an IDC. Operating the IDC uses two different systems, i.e. from the telephony system to the radio-frequency system or vice versa with a half-duplex mechanism.
A control unit based-on web in smarthome system has been designed and constructed. The control unit can be integrated into the smarthome system platform for gate operation via a smartphone. The research objectives, namely (i) integration of hardware and availability of raw files for applications, (ii) programming for control unit, and (iii) availability of control unit and implementation of validation tests. The result of integration is a form of successful hardware handshaking. The programming result is a form of successful software handshaking, including (i) a flowchart-based algorithm, while the syntax structure is based on the Arduino IDE, (ii) the comfiling and uploading stages of the syntax structure to the Arduino UNO R3 module, including the process online control based on RemoteXY version 4.5.1 via a web browser, and (iii) uploading files from personal computers and smartphones based on Android. The availability of the control unit physical building for the validation test process is the achievement of handshaking in hardware and software, in the form of performance measurement of the control unit with 3 (three) kinds of observations, namely (i) “open”, (ii) “close”, or (iii) lock/unlock state. In general, it is concluded that the web-based control unit on the smarthome system for gate operation can function and perform according to plan.
