ENERGY CONTROL SYSTEM

Abstract

The invention is an Energy Control System consisting of three main components: Energy Control Unit (1), RFID Card Reader (2) and Door / Window Sensor (3). This system is designed for use in accommodation and similar institutions such as hotels, motels, guesthouses, and dormitories. The system aims to automatically switch off the room electricity and other electronic devices when no one is in the room or when the balcony door or window is opened while the air conditioner is running. At the same time, damage to the air conditioner is prevented by switching it off via its remote control rather than cutting off its power. In this way, energy savings are achieved while also preserving the lifespan of the devices.

Description

1 TARIFF ENERGY CONTROL SYSTEM Technical Field to Which the Invention Relates This invention allows air conditioners used in hotels, hospitals, workplaces, and government institutions to be 5 times more efficient. an energy saving system that aims to ensure efficient operation and energy savings The system is related to an RFID card reader (2) that can only work with the hotel's original RFID cards. It includes wireless door and window sensors. When a door or window is opened... Turn off the air conditioner using the original remote control deactivation code (infrared code) from the air conditioner manufacturer. It closes securely. 10 State of the Art Existing RFID card reader(2) systems are generally mechanical switch or magnetic based. Instead of comparing card IDs, it simply checks that the card is inserted into the card reader via the card's antenna. It works by magnetically sensing the light. Therefore, hotel guests should check the door when leaving their room. They took their cards with them and inserted another card into the card reader; this resulted in 15 unnecessary cards in the room. It causes electricity consumption. Current door and window sensors are generally magnetic in nature and require electricity to function. This requires running cables from the control panel to the relevant points. This is especially true in hotel construction. Installations carried out after completion incur additional modifications and costs. Additionally, in existing systems, when a door or window is opened or when a card is swiped from the card reader, card 20 When unplugged, the electricity is cut off immediately. These sudden interruptions affect air conditioners and other electronic devices. This can lead to malfunctions. Technical Problems That the Invention Aims to Solve In the developed system, the RFID card reader (2) only accepts the defined 13.56 MHz RFID cards. It works with this system. This means that when leaving the hotel room, you don't need to take your user card with you. 25 This is because a different card cannot be used. This situation leads to unnecessary energy consumption in the room. This prevents unnecessary operation of air conditioning and other electrical systems, thus saving energy. Savings are achieved. There is no connection between the door and window sensor (3) and the RFID card reader (2) and the energy saving relay. There is no cable connection. This allows for easy system installation and 30 It eliminates the need for renovations, especially in existing buildings, thus preventing additional costs. The air conditioner shut-off button signal defined to the door window sensor(3) is signaled according to the signal protocol. The air conditioner is switched off by producing air. When the card is removed from the RFID card reader(2) or the door / window is opened, the system first The air conditioner is switched off using its own remote control shutdown code (IR signal). This process takes 35 minutes. The power is cut off after approximately 3 seconds. This prevents sudden interruptions that could damage the air conditioner. It will be over. 2 This system is suitable for hospitality facilities, public institutions, and others that want to achieve energy efficiency. It can be easily used by businesses. Also, the electricity is not cut off directly when the door or window is opened; it is first supplied to the air conditioner via the IR LED. A self-shutdown command is sent. This ensures the air conditioner shuts down safely, extending the device's lifespan. It will be extended. 5 The door and window sensor (3) works with an IR signal, so no other control device is needed. It can also be used. When this small device is applied to the balcony doors of official and private institutions, the door By enabling the air conditioner to automatically switch off when it is on, it significantly saves energy.

Figure 1 - Section 3.5: 10 A magnet causes a reed relay to move due to the magnetic field of the magnet as it approaches or moves away from the magnet. the contacts close or open Description of the invention One master card and 15 cards are required for the card reader (2) as many cards as the reader is required to work with. The card is introduced to the program software-wise. Card introduction by the user is very easy; master When the card is inserted into the RFID card reader (2), all card information in the reader is erased, then the following Five cards are inserted into the RFID card reader (2) one after the other (for example, if five cards are to be used). RFID card reader (2) stores the ID numbers of these cards in memory. No card will work except for these 5 cards that it stores in memory. When the guest enters the room and inserts the RFID card into the RFID card reader (2), the RFID card reader (2) displays the card 20 It verifies by reading the ID. If it's not one of the defined cards, no transaction will be made. The card sends a signal to the R terminal of the Energy Control Unit (1) to turn on the room electricity. The microcontroller (MCU) transmits the on signal from the R terminal (1) to the energy control unit (1.3) and the relay The unit (1.2) activates the room electrical relay. When the relevant relay is activated, the FI on the power terminal (1.4) is activated. The phase entering from terminal (IN) exits from terminal FO (AUT), thus supplying electricity to the room. 25 If the door and window sensor (3) is closed, the reed relay (3.3) is close to the magnet (3.5). Therefore, the ignition will be off and it will send a signal to the RFID card reader (2) to turn on the air conditioner. When the RFID card reader (2) receives the signal to turn on the air conditioner, it switches to the Energy control from the K terminal (2.1) on it. It transmits the opening signal to the K terminal of the unit(1). The signal from the K terminal of the energy control unit (1) reaches the MCU (1.3), the MCU (1.3) turns on the air conditioner 30 It activates the air conditioning relay in the relay unit (1.2). COM and NO terminals on the power terminal (1.4) It acts as a switch for the air conditioner, supplying electricity to it and enabling it to operate. When the door or window is opened, the reed relay (3.3) located on the door or window sensor (3), Since it will move away from the magnet (3.5), the relay contact will open and the air conditioner will turn off signal IR sensor (3.4) 35 The signal is sent to the air conditioner, turning it off. After 3 seconds, this information is also sent to the Wi-Fi. The signal to turn off the air conditioner is transmitted from the network to the RFID card reader (2). The RFID card reader (2) turns off the air conditioner. When received, the K terminal on the terminal (2.1) is switched off to the K terminal of the energy control unit (1). It transmits the signal. The signal from the K terminal of the power control unit (1) reaches the MCU (1.3), The MCU (1.3) releases the air conditioning relay in the relay unit (1.2) to turn off the air conditioning. Power 40 The COM and NO contacts on terminal (1.4) are disconnected and the air conditioner switches off. When an RFID card is removed from the RFID card reader(2), the information that the card has been removed is sent to terminal (2.1) It transmits from the R terminal on it to the R terminal of the Energy control unit(1). The R terminal of the Energy control unit(1) The signal from the end reaches the MCU(1.3), the MCU(1.3) signals to turn off the room electricity and the air conditioner. After a few seconds, it releases the room electricity and air conditioning relay in the relay unit (1.2). Power terminal (1.4) The phase electricity to the FO terminal is cut off, and simultaneously the COM and NO contacts are separated, and the air conditioner... It closes.
