    PLC Based IOT Controlled Electric Protection System
    (COMSATS University Islamabad, Lahore Campus Library Information Services, CUI Lahore, 2018) M. Fahad Saeed , Zain Ahmad Javed , Laraib Ali,; FA15-EEE-002 , FA15-EEE-028 , FA15-EEE-040; Ayesha Ali, Assistant Profesor; LHR TP 5865
    PLC based IOT controlled Electric Protection System is based on a circuit breaker that can only be remotely controlled by the lineman himself, designed to provide security to the maintenance staff and households while repairing the electrical lines. When operated manually we see fatal electrical accidents to the linemen is increasing during the electric line repairing due to lack of communication and coordination between the maintenance staff and electric substation staff. In order to avoid such accidents, the circuit breaker can be designed such that only authorized person can operate it with the help of password based IOT application. By using it operator can control the circuit breaker while he is away from the workstation and keypad is used to enter the password to control it when the operator is in the workstation. A relay is used to open or close the circuit breaker. Any wrong attempt to open the breaker an alert will be displayed on the mobile screen through the application and display the status on the HMI. Furthermore, the system will detect faults, maintain a profile of the connection and provide alarms to linemen if the connection is running on above 70 percent of the prescribed load.

    Smart Fuelling System
    (comsats university islamabad lahore campus, 2020) Sh M Hassan Ali , Mughees Iqbal , Muhammad Ali; , FA15-BCE-046 , FA15-BCE-049 , SP15-BCE-039; Wajeeha Khan ERNAL, Assistant Profesor; LHR TP 5910
    The main aim of this project is to design a system that revolutionizes the fuelling stations and to create a cashless environment. With the world going in the direction of digital payment and automatic systems, this project will be the basis of a necessary change in the future. This project has been designed to automatically perform transactions of a dispensing system of fuel, based on user accounts associated with the system. Smart Fuelling System is directly associated with the RFID technology. Experimental and practical use of RFID for vehicle identification, toll collection and traffic management has already been experimented extensively. RFID technology uses RFID reader, RFID tag that collects the information about vehicle when a vehicle equipped with RFID tag comes to the fuel station and when he leaves the fuel station the amount of fuel, he gets from station, is automatically deducted from customer’s prepaid account. Through the GSM technology, a text will be sent to the client, which will carry all the details of the transaction. With the help of RFID technology, a UID will be registered using vehicle owner’s information. This registered account will be prepaid and rechargeable. The amount of transaction will be will be made available to the customer on a website where he can login anytime. iv
