    Automatic Object Identifier and Image Recognizer (AOR)


    The entire idea of our research project is to identify the patterns automatically with the help of classifier algorithms. The entire mission is to divide each of the input features into a number of intervals, so that the value of a feature can be specified approximately and it will be matched with the existing pattern to identify the object automatically. Pattern recognition on a system is about predicting the data which is unknown in nature of an observation, a discrete data quantity such as black or white information, one or zero natured data, real or fake informations. An observation of the information is a collection of manipulated numerical measurements such as an image, a vector of weather related data, an electrocardiogram related informations which may be utilized in medical field. In our system, we are trying to utilize classifier algorithm to classify individual elements in the images and afterwards the individual items will be tuned up and matched with the existing patterns and identify the numbers and recognise the number plate of the individuals.

    IEEE Title:

    Automatic License Plate Recognition (ALPR): A State-of-the-Art Review

    IEEE Abstract:

    Automatic license plate recognition (ALPR) is the extraction of vehicle license plate information from an image or a sequence of images. The extracted information can be used with or without a database in many applications, such as electronic payment systems (toll payment, parking fee payment), and freeway and arterial monitoring systems for traffic surveillance. The ALPR uses either a color, black and white, or infrared camera to take images. The quality of the acquired images is a major factor in the success of the ALPR. ALPR as a reallife application has to quickly and successfully process license plates under different environmental conditions, such as indoors, outdoors, day or night time. It should also be generalized to process license plates from different nations, provinces, or states. These plates usually contain different colors, are written in different languages, and use different fonts; some plates may have a single color background and others have background images. The license plates can be partially occluded by dirt, lighting, and towing accessories on the car. In this paper, we present a comprehensive review of the state-of-the-art techniques for ALPR. We categorize different ALPR techniques according to the features they used for each stage, and compare them in terms of pros, cons, recognition accuracy, and processing speed. Future forecasts of ALPR are given at the end.

    [38] Remote Control of Automation Systems for DES Courses:

    The objective of technical courses is the transfer of knowledge and know-how to students. In the case of discrete event system courses, it is important for a learner to locally or remotely control real systems(or plants) that are composed of many sensors and actuators. The use of these devices poses several problems. First, it is difficult to adapt them to the student's level (from beginner to expert). Second, these systems are generally designed with industrial components. An error on the control-command design can involve safety problems and breakdowns. In this paper, the authors propose an original solution to solve these two problems. To guarantee the safety of the operators and the equipment, an approach using a validation filter is proposed. It is based on the definition of logical constraints, which should in no case be violated. To adapt the difficulty level, it is proposed to modify the level of automation. For that, the functional dimension of the automation system is modified to adapt the student's level of autonomy. The level of automation is defined by the teacher by means of a functional analysis of the system.

    [39] Workflow and decision support for the design of distributed automation systems:

    Distribution of automation functions onto several controllers has become a widely applied answer to the demands of huge and complex automated systems. Distributed networked automation systems offer advantages regarding various nonfunctional requirements, such as flexibility, availability and maintainability.

Control engineers face difficulties in coping with all non-functional requirements when designing distributed networked automation systems, as there are trade-offs between them. A complete and detailed model of the automation system, including all computation and network effects, is usually not available. Therefore, control engineers have a demand for support when making design decisions for distributed networked automation systems.

    In general, it is difficult to realize the optimal operation of waste water treatment plant because of its complex nature (e.g., highly nonlinear, seriously coupled, higher order, time-varying and frequent variation of operating condition). An integrated automation system consisting of two layers: process manage system (PMS) and process control system (PCS), is developed to overcome the problem of high production costs in wastewater treatment plants in China because of low automation level. The structure, function and control strategy of the system are discussed. The system proposed in this paper has been successfully applied to the wastewater treatment plant in the southern suburb of Shenyang, realizing the optimal control of overall production index including wastewater treatment yield, treated wastewater quality and production cost. It has been found to provide great benefits for both economy and society.

    [42] Real-Time Adaptive Automation System Based on Identification of Operator Functional State in Simulated Process Control Operations:

    This paper proposes a new framework for the online monitoring and adaptive control of automation in complex and safety-critical human-machine systems using psychophysiological markers relating to humans under mental stress. The starting point of this framework relates to the assessment of the so-called operator functional state using psychophysiological measures. An adaptive fuzzy model linking heart-rate variability and task load index with the subjects' optimal performance has been elicited and validated offline via a series of experiments involving process control tasks simulated on an automation-enhanced Cabin Air Management System. The elicited model has been used as the basis for an online control system via the predictions of the system performance indicators corresponding to the operator stressful state. These indicators have been used by a fuzzy decision maker to modify the level ofautomation under which the system may operate. A real-time architecture has been developed as a platform for this approach. It has been validated in a series of human volunteer studies with promising improvement in performance.

    [45] Modeling distribution automation system components using IEC 61850:

    IEC 61850 was proposed as a standard protocol for communications within the substation. In its current edition, the standard does not cover communications outside the substation, either with the control center or with other substations, for instance for remote protection. However, during the recent years, there has been a general belief that some features of the standard can be efficiently utilized for applications outside the substation as well. With the advent of new monitoring and control technologies the idea of power system automation at the distribution system and feeder level is crossing new boundaries. In such applications, accessing the accurate data is a necessity. With its future-proof object oriented structure, IEC 61850 can provide comprehensive and accurate information models for various components of distribution automation systems. This paper provides some examples on how the standard can be employed for this purpose, and what measures need to be taken to enable it to efficiently respond to some of the emerging technologies in distribution automation systems.

    More About Android Application

    Automation or automatic control, is the use of various control systems for operating equipment such as machinery, processes in factories, boilers and heat treating ovens, switching in telephone networks, steering and stabilization of ships, aircraft and other applications with minimal or reduced human intervention. Some processes have been completely automated.The biggest benefit of automation is that it saves labor, however, it is also used to save energy and materials and to improve quality, accuracy and precision. The term automation, inspired by the earlier word automatic (coming from automaton), was not widely used before 1947, when General Motors established the automation department. It was during this time that industry was rapidly adopting feedback controllers, which were introduced in the 1930s. Automation has been achieved by various means including mechanical, hydraulic, pneumatic, electrical, electronic and computers, usually in combination. Complicated systems, such as modern factories, airplanes and ships typically use all these combined techniques. Two common types of automation are feedback control, which is usually continuous and involves taking measurements using a sensor and making calculated adjustments to keep the measured variable within a set range, and sequence control, in which a programmed sequence of discrete operations is performed, often based on system logic. Cruise control is an example of the former while an elevator or an automated teller machine (ATM) is an example of the latter. The theoretical basis of feedback control is control theory, which also covers servomechanisms, which are often part of an automated system. Feedback control is called "closed loop" while non-feedback control is called "open loop." Feedback control is accomplished with a controller. To function properly, a controller must provide correction in a manner that maintains stability. Maintaining stability is a principal objective of control theory. As an example of feedback control, consider a steam coil air heater in which a temperature sensor measures the temperature of the heated air, which is the measured variable. This signal is constantly "fed back" to the controller, which compares it to the desired setting (set point). The controller calculates the difference (error), then calculates a correction and sends the correction signal to adjust the air pressure to a diaphragm that moves a positioner on the steam valve, opening or closing it by the calculated amount. All the elements constituting the measurement and control of a single variable are called a control loop. The complexities of this are that the quantities involved are all of different physical types; the temperature sensor signal may be electrical or pressure from an enclosed fluid, the controller may employ pneumatic, hydraulic, mechanical or electronic techniques to sense the error and send a signal to adjust the air pressure that moves the valve. The first controllers used analog methods to perform their calculations. Analog methods were also used in solving differential equations of control theory. The electronic analog computer was developed to solve control type problems and electronic analog controllers were also developed.[3] Analog computers were displaced by digital computers when they became widely available. Common applications of feedback control are control of temperature, pressure, flow, and speed.Sequential control may be either to a fixed sequence or to a logical one that will perform different actions depending on various system states. An example of an adjustable but otherwise fixed sequence is a timer on a lawn sprinkler. An elevator is an example that uses logic based on the system states to perform certain actions in response to operator input A development of sequential control was relay logic, by which electrical relays engage electrical contacts which either start or interrupt power to a device. Relays were first used in telegraph networks before being developed for controlling other devices, such as when starting and stopping industrial-sized electric motors or opening and closing solenoid valves. Using relays for control purposes allowed event-driven control, where actions could be triggered out of sequence, in response to external events. These were more flexible in their response than the rigid single-sequence cam timers. More complicated examples involved maintaining safe sequences for devices such as swing bridge controls, where a lock bolt needed to be disengaged before the bridge could be moved, and the lock bolt could not be released until the safety gates had already been closed.The total number of relays, cam timers and drum sequencers can number into the hundreds or even thousands in some factories. Early programming techniques and languages were needed to make such systems manageable, one of the first being ladder logic, where diagrams of the interconnected relays resembled the rungs of a ladder. Special computers called programmable logic controllers were later designed to replace these collections of hardware with a single, more easily re-programmed unit. In a typical hard wired motor start and stop circuit (called a control circuit) a motor is started by pushing a "Start" or "Run" button that activates a pair of electrical relays. The "lock-in" relay locks in contacts that keep the control circuit energized when the push button is released. (The start button is a normally open contact and the stop button is normally closed contact.) Another relay energizes a switch that powers the device that throws the motor starter switch (three sets of contacts for three phase industrial power) in the main power circuit. (Note: Large motors use high voltage and experience high in-rush current, making speed important in making and breaking contact. This can be dangerous for personnel and property with manual switches.) All contacts are held engaged by their respective electromagnets until a "stop" or "off" button is pressed, which de-energizes the lock in relay. See diagram: Motor Starters Hand-Off-Auto With Start-Stop (Note: The above description is the "Auto" position case in this diagram)Commonly interlocks are added to a control circuit. Suppose that the motor in the example is powering machinery that has a critical need for lubrication. In this case an interlock could be added to insure that the oil pump is running before the motor starts. Timers, limit switches and electric eyes are other common elements in control circuits.Solenoid valves are widely used on compressed air or hydraulic fluid for powering actuators on mechanical components. While motors are used to supply continuous rotary motion, actuators are typically a better choice for intermittently creating a limited range of movement for a mechanical component, such as moving various mechanical arms, opening or closing valves, raising heavy press rolls, applying pressure to presses.
