| 2.3 Proposed system The system consists of a set of electronic relays that are connected in series to every circuit in the home. The switches are connected to entire circuits rather than individual appliances. They are connected in series with the already existing overcurrent circuit breakers i.e. after every circuit breaker, an electronic switch will be included to control the associated circuit. The electronic relays will be chosen such that their current specifications allow them to handle the currents drawn by the associated circuits. They will be connected to the output of the Arduino microcontroller unit and will act as its actuators. For dedicated circuit breakers, a current meter will be provided to determine if any heavy appliances are drawing current. Current meters will be connected to any circuits to which the user expects that heavy and potentially hazardous appliances such as flatirons will be connected. An energy meter will be also be part of the system and it will be used to set energy limits whereby after a particular limit in a month, predetermined modifications to home power usage will be effected. The current meters and energy meter will be provide input to the microcontroller unit. A companion mobile android application will be provided for controlling the system from a user's android phone. A Bluetooth module and a GSM module will be used for short and long range communication between the system and the user's phone. 7 Figure 1 Proposed System 2.3.1 Benefits the system has over the systems already in use that were previously reviewed This system provides control to an entire home circuit and thus a collection of outlets rather than individual appliances. This makes the system more compact and gives a holistic lower level control of the electrical appliances. In simple terms, appliances are controlled in batches rather than individually. The system provides features that are directly intended at optimizing home energy usage. It incorporates an energy meter that is used to keep track of all energy used so that certain predetermined circuits will be switched off when a particular energy threshold is crossed in a month. The system also enables the user to automate on and off times of security lighting circuits so as to prevent power wastage. The system does not utilize sensors to carryout its tasks. Sensor based systems can pose many challenges such as, limited area of use, practical difficulties, Higher costs, longer payback and in many instances lower productivity. A control system's lifetime cost increases when sensors are added. The price of the sensors themselves comes first. Second, it needs experience to accurately install and calibrate them, which costs time and money. Third, there is the continual cost of making sure that your sensor-control layout keeps up with the modifications made to the building. Rewiring and moving sensors are frequently needed to accomplish this. 8 Additionally our system unlike all that have been reviewed keeps track of all sensitive circuits i.e. circuits to which heavy and/or hazardous equipment will be connected by incorporating current meters. The user will get alerted if circuits draw heavy current fora given amount of time and they'll be able to turnoff these circuits in case anything is wrong. Download 0.89 Mb. Share with your friends:
