It means that each production cell electrolytic tank has its power gap target. When the control computer sends a signal to drive the feeders, and for some reason, such feeders are not triggered, it means that some physical problem may be occurring.
In this case, a physical intervention such equipment is required. For this task, they are designated process technicians who perform the repair and the reestablishment of the operation of the feeders and voltage busbars.
The problem becomes complex when technicians deal in a potroom environment with large amounts of electrolytic cells arranged in large rooms and corridors in an aluminum production plant. For  would be a piece of hardware or a computer system based on software that enjoys some properties, such as learning autonomy, responsiveness, pro-activity and social skills.
Figure 3 shows the interaction between two or more agents in a computer system and configures a Multi-Agent System where these work together to perform certain tasks or perform a set of goals. Scientific research and the practical implementation of Multi-Agent Systems is focused on building standards, principles and models that allow the creation of small and large companies of semi-autonomous agents, able to conveniently interact in order to achieve their objectives .
Structure of a Multi-Agent System 3. JADE provides certain features, such as distributed applications that exploit the use of software agents. Being built on the Java platform, enables deployed agents using the JADE framework, which can run on any operating system OS , which makes it ideal for environments where you can not get information about the OS used .
Auml was proposed as an extension of UML Unified Modeling Language , which uses decomposition, abstraction and organization to reduce the complexity of software development, decomposing a system in small parts of objects, models, use case or class, several operational actions. In relation to abstraction, it provides a specialized abstract view of modeling class, use case diagram of interface etc. The Auml offers structures as a class diagram and interface to show how agents can be erected in an agent system.
The model focuses on a point at a time, increasing the ability to understand the issues to complex problems during the lifetime of the system design. This is accomplished by introducing a new class diagrams UML diagrams protocol. These extend diagrams and sequence diagrams of UML state, as shown in Figures 4 and 5.
Figure 4. Typically, they are implemented from different technologies such as microprocessors, microcontrollers, DSP, reconfigurable circuits, analog circuits and microwave and even microelectromechanical systems MEMS - Micro Electro Mechanical Systems .
The board is fed by a micro-USB port, with 5V voltage and requiring at least mA, with waste of energy varying in 3. For operating system installation it is necessary that the card has at least 2 GB capacity for all the necessary files.
The operating system commonly used is the Raspibian, a distribution recommended by Raspberry Foundation, based on Debian . Figure 6. The system alerts drivers if a child is left unattended in the vehicle in order to prevent the child from being exposed to high or low temperatures inside the vehicle. To this end, sensors are used to capture data via occupancy sensors, temperature and distance. The data captured by the sensors determine the need to alert sent to the vehicle owner driver if an occupant has been left inside the vehicle, still controlling some functions of the vehicle, allowing foreign individuals to rescue him, with the unlocking of doors, windows opening, with possible activation temperature of the automobile system.
Kumar et al. Through multiple sensors, the system evaluates the extent of danger exhibited by a person or animal within the confines of the residence, conveying the owner of the residence, the various information about critical events generated. Ramya  presents a construction work involving containing a microcontroller system for detecting and warning of toxic gases, particularly propane and LGP.
If the gases exceed acceptable limits, the system immediately generates an alarm and also send SMS alert message to authorized persons using GSM technology. Gaspar et. Morales  created and patented a monitoring and alarm system in a network audio link that detects sound alarms triggered and inform the responsible authorities.
Implemented for PC type computers or other premises of processors, different sound coming from different alarms, classifies the sound as a specific alarm by FFT processing and distributes the alarm over the Internet, public telephone switches, or other communication links to central station, which then distributes the alarm to the authorities.
In another embodiment, the alarm reports are generated directly from the PC to the residence or specific company where authority is located.
All diagrams were constructed using the free tool-day standard 0. Diagram Use Cases Figure 7 shows the actors are placed in the context of the proposed approach and its use cases, showing the set of paths that agents can run through the system, each with a discrete goal. Figure 7.
Diagram Use Cases of the proposed system The use case Send audio alarm, converts the textual words received by dividing each of them into audio files eg.
Is represented in this case, the level of interaction between players by exchanging messages and activation through behaviors. Figure 8. State Transition Diagram of the Proposed System Through this diagram, we see the main actors interacting in the sending and receiving of text messages parameterized Controller and Speech that is validated, converted to audio and broadcast. Diagram Deployment The deployment diagram shown in Figure 9 detailing the distribution of the proposed solution in a generic environment potroom controlled by the controlling computer.
It is observed that the bundled solution raspberry pi plate is arranged in the process control network, in the same environment controllers.
The audio channel raspberry card is connected to speakers arranged in the potroom. Therefore, the power pulses, ascent and descent bus, when they jammed by mechanical failures in the vats can be signaled in the form of beep, in which the solution proposal report to the operator exactly what existing physical problem.
Block Diagram of the Proposed Solution Each controller agent is responsible for receiving the parameterized messages generated by the control computer in which the agent is inserted.
From the generation and reception of such text messages, with the use of multi-agent platform JADE, the controlling agents send text messages with the problem identified in a given tank to the centralizing agent, which queues the message and is in charge of is converted it audio, transferring them to the speakers of the respective room vats, where the pot with problem lies.
The solution proposed is the block diagram shown in Figure Deployment Diagram of the Proposed System Figure The centralizin centralizingg agent identifies the queue textual alarm messages that are sent in FIFO order first first-in, first-out out to the potroom in an audible format, as a warning system, which helps in faster diffusion of the critical situation found.
The prototype of the proposed system ystem is shown in Figure Figure Prototype of the Proposed System 8. For demonstration purposes they were made simulation controllers pot and controlling and centralizing agents responsible the generation and transmission of alarms in audio format for the tanks room, respectively.
The extent to which the controllers identify some kind of problem in a particula particularr pot, textual message of the problem in question, parameterized for the pot number identifier is generated and transmitted to the controller agent forwards to the centralizing agent.
Podemos encontrar a linguagem C em diversos lugares. Monte conforme a figura a seguir: Existem IDEs que suportam diversos tipos de linguagem. Veja a seguir: Configura os resistores internos de pull-up ou pull-down. No segundo exemplo utilizaremos uma chave push button para acender e apagar o LED. Neste exemplo faremos um LED piscar de 1 em 1 segundo. Salve o arquivo e aperte F9 Build e depois F5 Execute para executar o programa. Neste exemplo iremos ligar e desligar o LED pela chave push button.
Gostou de programar em linguagem C? Mas seria legal dar uma olhada no datasheet do processador.
Esse tutorial por exemplo, usou uma biblioteca lcd. Esse outro implementou a leitura do sensor DHT11 diretamente, usando apenas a biblioteca WiringPi http: Primeiramente parabens pelo artigo.
Gostaria de tirar uma duvida, poque eu nao estou conseguindo executar o codigo? Me retorna este erro. No such file or directory gcc: Compilation failed. Deve ficar assim: Boa tarde, estou precisando desenvolver um sistema no qual envolve um banco de dados.
