Password based circuit breaker operation for the safety of lineman during maintenance work

摘要

Nowadays, accidental death of lineman is a commonly occurring tragedy. so, it is compulsory for us to guarantee the safety of linemen by adapting a new method of operation. A new system should be adapted to regulate and manage the control panel which consists of all the electrical components and circuit breakers. These accidents are on the rise throughout the country, main reason being miscommunicationbetween the maintenance workers and sub-station workers. The planned system gives a solution for this problem and reduces the risk for linemen. The control to activating/ deactivatingthe control panel is in the hands of the linemen only. In this new method of operation, a "Passcode or Password" is needed to access the control panel and further to operate the circuit breaker (ON/OFF). An encrypted Passcode/Password is sent form the substation to the circuit breaker operators(linemen), for the purpose executing maintenance works. The password is registered and forwarded to the lineman's mobile and also to the management panel by the help of GSM module. The received passcode/password is typed in through the matrix keyboard which acts as the input device and also it is interfaced to the microcontroller present inside the panel. T.
