Accidents occurred at night time are mainly due to carelessness of human being such as sleepiness. To avoid that we design and develop a control system based on intelligent electronically controlled automotive braking system. It consists of IR transmitter and receiver circuit, control unit, pneumatic breaking system. The IR sensor is used to monitor the eye blink movement. If the eye blink movement varies beyond the normal condition set 3 sec the IR sends the control signal to the breaking system through electronic control unit ECU . Thus the pneumatic breaking system is used to break the system and alerts the driver to not sleep. From this accidents can prevent before it occurs. Chandra Mohan M | Arivazhagan.

Abstract: Remote surveillance of our house, as well as office areas, has become an important aspect. Human surveillance is achieved by moving (troop or equipment) personnel near sensitive areas to constantly monitor the area. But humans have their limitations, and deployment in inaccessible places is always impossible. We have developed a robot that can be used for video surveillance & monitoring which can be controlled through a GUI. Using this project, we put forward a surveillance robot with an Interface Board of the Raspberry Pi and Software to fulfill Real Time requirements. The Raspberry Pi Robot has a personalized digital device with peripherals such as Raspberry PI, LED lights, a Personalized Camera, Speaker for text to voice conversion and security or threat alarms, a range sensor, etc. The base controller of the robot will be the Raspberry Pi 3. A webcam attached to the Pi monitors the area with Live Streaming. The live streaming ability of the Pi allows the camera feed to be analyzed from any location using the internet. For detecting the obstacles we had used an ultrasonic range sensor along with it to give commands or pass on messages wehave installed a speaker which will convert text to voice which is an E-speak technique. With such a system, every user will feel more safe, secure, and sheltered while they're not at their place of residence or when they've left their kids and geriatric alone at home.

Most times in engineering and other fields, engines need to be transformed from one form to another, in circuits and most components we are familiar with, electrical engines, impulses, digital information, etc need to be changed from one level to another, a motor does this, be it in any kind, pending on the desired function. This literature review examines various research studies that have been done using the PIC 16F84 microcontroller to control stepper motors. The PIC 16F84 is a popular choice for stepper motor control applications due to its simplicity, low cost, and ease of programmability. This review highlights several key control techniques implemented using the PIC 16F84, including full-step mode, half-step mode, closed-loop control with position feedback, and speed control. The peripheral interfacing aspects are also discussed, covering the integration of stepper motor driver circuits, rotary encoders, and user interface components. The firmware development approaches for the PIC 16F84 are explored, demonstrating how researchers have programmed the microcontroller’s digital I/O, timers, and interrupts to precisely control the stepper motor windings and respond to feedback signals. While the PIC 16F84 has proven to be a capable platform for stepper motor control, the review also identifies some limitations, such as the microcontroller’s restricted resources and potential scalability challenges as the complexity of the control system increases. Suggestions for future research include exploring more advanced microcontrollers, integrating the PIC 16F84 with additional hardware, and developing more sophisticated control algorithms to enhance the performance and robustness of the stepper motor control systems. The CMOS circuit stands as the drive circuit between the PIC IC and the stepper motor which provides precision in advanced control methods of design and production.

The continuing advances in the performance of network servers make it essential for network interface cards (NICs) to provide more sophisticated services and data processing. Modern network interfaces provide fixed functionality and are optimized for sending and receiving large packets. Network interface cards allow the operating system to send and receive packets through the main memory to the network. The operating system stores and retrieves data from the main memory and communicates with the NIC over the local interconnect, usually a peripheral component interconnect bus (PCI). Most NICs have a PCI hardware interface to the host server, use a device driver to communicate with the operating system and use local receive and transmit storage buffers. NICs typically have a direct memory access (DMA) engine to transfer data between host memory and the network interface memory. In addition, NICs include a medium access control (MAC) unit to implement the link level protocol for the underlying network such as Ethernet, and use a signal processing hardware to implement the physical (PHY) layer defined in the network. To execute and synchronize the above operations NICs also contents controller whose architecture is customized for network data transfer. In this paper we present the architecture of application specific controller that can be used in NICs.

A method of developing a maximum power point tracking (MPPT) algorithm for photovoltaic (PV) utilizing a peripheral interface controller (PIC) is presented in this paper. The efficiency and adequacy of a PV depend on the temperature and the exposed position to the sun. Thus, there is an optimum point at which the operating power is at maximum. The goal is to operate the PV module at this point (MPP). It can be accomplished by using the MPPT algorithm designed with a DC-DC boost converter. The boost converter, MPPT circuit, PIC18F4550 microcontroller and PV panel are the main components used in this design. The current and voltage produced by the solar panel are observed continuously by a closed-loop control system. The microcontroller-based control system adjusts the duty cycle of the converter to extract the maximum power. With a DC input voltage of 15 V, the boost converter is capable of generating an output voltage of an approximately 60 Vdc at a maximum power of 213.42 W with minimum voltage ripple as compared to 84 W without the MPPT. It proved the effectiveness of the developed algorithm.

It consists of gas sensor for detecting the fire, temperature sensor for sensing the environmental temperature, relay driver for pump control, alarm system and fire extinguishing system. When the temperature sensor detects a predefined temperature, the LED and buzzer will be turn on. When the smoke detector gas sensor senses a certain amount of smoke, the LED and buzzer will turn on. If both the temperature and smoke reach a predefined level, the alarm will ring and the extinguishing system will also activate, too. The advantage of this project is to reduce the amount of damages done by fire. The weak point of this project is the power supply using AC, so it will not work when electricity is out.

Traffic light plays an important role in the urban traffic management. Therefore, it is necessary to improve the traffic controller for effective traffic management and better traffic flow leading to greener environment. In this paper, an advanced and intelligent traffic light controller is proposed, utilising the fuzzy logic technology and image processing technique. A fuzzy logic control has been implemented to provide the attribute of intelligence to the system. For real-time image acquisition, the process is further linked to the fuzzy logic controller which generates a unique output for each input pattern. Here image processing and fuzzy logic tool boxes of MATLAB are used where the final output is sent to Peripheral Interface Controller (PIC) microcontroller to drive the traffic signals in the desired manner. The results obtained show an improvement of 44% in the overall outcome of traffic management as compared to the conventional traffic controller, marking great feasibility and practicality of the current model.

It was intended from the outset to allow simpler integration of 3rd party sensor-based process monitoring equipment to facilitate optimised machining, including Adaptive or Intelligent control techniques. These peripheral devices from different suppliers must be analysed and classified depending on specific functionality, and a common programming and operating interface presented to the developer and user. Other device types on the machine such as operator panels and motion /axis control hardware have been identified and incorporated. An Open Device Interface (ODI) framework is proposed and defined: the development of this generic software structure and associated libraries masks specific underlying details of a devices implementation and allows simpler incorporation of additional features to the machine. The requirements for the transmission, handling, display and logging of process data is presented, and the successful demonstration of the new system on a universal grinding machine with sample peripheral devices is reported. The applicability of the Open Device Interface structure to other generalised control devices and monitoring applications is also discussed.

Full textAbstract:
As one of the key technologies of Honeywell, the aeronautical radio incorporated (ARINC) 659 bus is popular in current space-borne computers. However, Honeywell does not design ARINC 659 bus controller separately, and there are only a few papers about FPGA-based ARINC 659 bus controllers. Accordingly, to promote the extremely high performance needs of space-borne computers, this paper designs an ARINC 659 bus controller chip which integrates two independent bus interface units (BIUs), one 8-bit MCU, and several peripheral interfaces (i.e., UART, SPI, and I2C). Because the two BIUs are identical and mutually checked, the symmetry problem is emphatically dealt with in the design of this bus controller, and effective timing convergence is realized, which makes the bus controller work reliably and stably. In addition, due to the circuit’s large scale, design for testability (DFT) is also considered. Accordingly, on-chip clock (OCC) and scanning compression test technique are used to realize the at-speed test and shorten the test time, respectively.

This paper presents a new, comprehensive digital circuit used for the control of a novel gas chromatograph mass spectrometer (GC-MS) interface that is based on supersonic molecular beam (SMB). The circuit includes a Texas Instruments 150 MHz digital signal controller (DSC), high voltage amplifiers for 8 independent channels and 4 independent channels of high resolution pulse width modulation (PWM). The circuit, along with a sophisticated embedded program and a custom made personal computer (PC) application, control all aspects of the interface: smart filament emission-current stabilization, static and scanning mass-dependent ion-source voltages, transfer-line heater proportional integral differential (PID) controls with thermocouple feedbacks, on/off valves, relays and several peripheral device controls that enable the full operation of a turbo-molecular vacuum pump, and of gas flow and pressure controllers. All aspects of this comprehensive controller were successfully tested. The signal for the 450 Th ion (C32H66) for example increased by 123% which is a significant increase. It is obvious that correctly tuned dynamic voltages can guarantee the optimal signal for each mass.

This is a survey paper on refrigeration monitoring systems designed using PIC microcontroller and FT811 display driver. PIC (Peripheral Interface Controllers) are a family of microcontrollers developed and produced by Microchip Technology. They are generally 8-bit or 16-bit controllers and feature a wide range of peripherals like ADCs, DACs, timers and communication interfaces. The FT811 is a graphic controller or an embedded video engine manufactured by FTDI chips. It generates images to be displayed on graphic TFT displays based on display list commands sent to it via a microcontroller through an SPI (Serial Peripheral Interface) channel. These commands can perform functions ranging from drawing lines, rectangles, displaying text and numbers, designing buttons, to loading images onto the chip’s RAM and display them on the screen. We are doing this as a part of our project as final year students belonging to the Electronics and Telecommunication branch from Pune Institute of Computer Technology.

Full textAbstract:
Abstract Hall sensors are commonly used as a non-contact way to relay positional data inside a cryostat to an external motion controller. However, cryogenic Hall sensors can be cost prohibitive and require peripheral electronics to interface with the motion controller. Here we contrast the accuracy and reliability of non-contact reed switches in cryogenic environments against the commercially available cryogenic Hall effect sensors. Accuracy for both units was optically measured using a wheel cooled down to 77K, while reliability and yield was determined by cooling multiple units down to liquid nitrogen (77K) and liquid helium (4.2K) temperatures. Lastly, we argue that the lower cost and ease-of-implementation of reed switches make them better suited for cryogenic motion control applications.

The creation of a remote-controlled fire robot is the primary objective of this project. The water tank and wireless pump on this robot both spray water. A Peripheral Interface Controller (PIC) microcontroller performs the functionality offered. The transmitter button sends instructions to the receiver, telling it to move the robot in front, back, left, and right. To run the DC motor through the motor controller Integrated Circuit (IC) for the necessary duty, the decoder decodes the data before sending it to another microcontroller. The remote control has a decent range of up to 100 metres with the right antenna. The water tank and water pump linked to the robot body are operated by the microcontroller's output in conjunction with the appropriate signal from the transmitter. An Arduino Uno series microprocessor controls the entire operation.

Full textAbstract:
This manuscript presents a robust tracking (servomechanism) controller for linear time-invariant (LTI) islanded (autonomous, isolated) microgrid voltage control. The studied microgrid (MG) consists of many distributed energy resources (DERs) units, each using a voltage-sourced converter (VSC) for the interface. The optimal tracker design uses the ellipsoidal approximation to the invariant sets. The MG system is decomposed into different subsystems (DERs). Each subsystem is affected by the rest of the system that is considered as a disturbance to be rejected by the controller. The proposed tracker (state feedback integral control) rejects bounded external disturbances by minimizing the invariant ellipsoids of the MG dynamics. A condition to design decentralized controllers is derived in the form of linear matrix inequalities. The proposed controller is characterized by rapid transient response, and zero error in the steady state. A robustness analysis of the control strategy (against load changes, load unbalances, etc.) is carried out. A MATLAB/SimPowerSystems (R2017b, MathWorks, Natick, MA, USA) simulation of the case study confirm the robustness of the proposed controller.

Present Automobiles are being developed with more electronics for efficient operation of vehicles.Earlier vehicles were built with an analog driver-vehicle interface for indicating various vehicle status like speed, fuel level, engine temperature etc. The driver-vehicle interface provides an interaction of driver with the dashboard for monitoring various parameters of the vehicle and it is designed in a way to help the driver to drive safely and comfortably. There are two types of driver-vehicle interface i.e, analog and digital. In the existing analog driver-vehicle interface, it is tough to build an automated driving system because most of the processing for decision-making regarding vehicle control uses digital electronic devices (like microprocessors etc) and requires data to be handled in digital format. Hence there is need to develop digital driving system that uses digital data throughout the processing there by making the decision process more transparent as well as easy for design. The automated driving system built using digital interface allows the driver to switch from manual mode to cruise mode (semi-autonomous), so that the vehicle adjust itself with respect to other vehicles in motion, thereby helps in safe driving. The paper develops and implements the digital driving system for a semiautonomous vehicle to improve the driver-vehicle interface. It uses an ARM based data acquisition system that uses ADC to bring all control data from analog to digital format and visualize through LCD. This paper isbased on CAN which uses embedded networking for efficient data transfer. It also takes feedback of vehicle conditions like Vehicle speed, Engine temperature etc, and are controlled by main controller. Additionally this unit equipped with GSM which communicates to the owner during emergency situations.

In Continental the, Electronic Control Unit (ECU’s) software consists of 2 parts, the basic software which is the generic part and the application software which does the product specific functionality. The project specific functionality depends upon the product type, like Body domain controller, immobilizer etc. Before the ECU is going to mass production, the controller has to be validated i.e., software and hardware. The main reason is to ensure, that once the ECU is fitted to the vehicle and there is a recall for ECU, it involves additional cost to the organization. The validation of the software includes, checking of the micro controller input, outputs, peripheral drivers, the initialization of the drivers, the timing measurement of the different components. All the parameters are controlled by the generic and application specific modules, and can be configured via configuration tool, manual configuration etc. Since the SW modules are complex and huge, so its need to perform validation of the SW modules manually. This is time consuming process, as it involves checking many c file, configuration files etc. The proposal is to automate the process using Python programming, which interacts with the C code, configuration files, debugger, interacting with the ECU’s peripherals, components and validate the Software parameters before going for series production. In the proposed method the different steps can be automated for different micro-controllers i.e., Renesas RL78 and RH850 used in the ECU’s and different architecture i.e., AUTOSAR and NON-AUTOSAR will be considered and the results will be compared with the manual validation effort and accuracy.

Since the past years, the microprocessor (8051) has been still playing an indispensable role as a controller in industry applications because of fast executing process, low-cost, small size and low power consumption, etc. It, however, usually lacks of long distance transmission, graphical interface and vision. On the other hand, VB is now a very popular software package for graphical interface design due to easy exploring and low price. Combining both superiorities as above, this paper develops a remote visional microprocessor-based monitoring and control platform using VB graphical interface. The nearby PC (server) can collect real-time sensing signals from the 8051 through RS232 and transmit it to remote PCs (client) for on line monitoring mechanism via Internet. Also, the client can send the control signals to the server and thus control the 8051. The real-time case study for feeding care in the Pet House is provided to verify its well performance and remote Web-based capability in term of fast, simple and robust performance.

Present-day computer systems have drastically transformed from the ones in days of basic file sharing, peripheral sharing or the hosting of companywide applications on a server to much more sophisticated, small and faster systems. These systems have further expanded to include cloud-based networks, virtualized desktops, servers, etc. The capabilities of evolving heterogeneous computer systems require advanced control plane. Software-defined networking (SDN) proposes to control the network from a centralized controller instead of a distributed configuration. SDN makes it easier for network operators to evolve network capabilities. Even though SDN proposes a logically centralized system, the controllers may not represent a single, centralized device, instead the control plane may consist of logically centralized but physically distributed controllers wherein each controller manages different administrative domains of the network or different parts of the flow space. There are mainly two types of control plane architecture: flat control plane and hierarchical control plane. In this paper, we have analyzed the reliability and availability of the hierarchical SDN control plane. We take into consideration work-load capacities of the controllers, link failures, node failures and controller-end failures to determine the reliability of the system.
