Smart Safety with Password Based GSM Module Controlling Circuit Breaker

Abstract

This paper focus on Smart safety with password based GSM module controlling circuit breaker. In our daily life, Safety is the major concern for all activities. Accidental death of a lineman is often read and proven in current scenario. In view, safety measures to protect operators are considered to be very necessary in current working. Using passwords for security, Electrical lineman security systems are used to control circuit breakers. Serious electrical accidents occurs becoming increasingly, when repairing power lines. It is happen due to lack of communication and coordination between maintenance and substation personnel. In the proposed system, the on and off line turning operation with the lineman to ensure the safety of linemen. For that, a secure password is required to operate the breaker operation and maintenance point of view. First request is registered and password is sent to the line operator\'s mobile phone and GSM module by AVR microcontroller. Entered password and password received by the GSM receiver are compare. If password is match, the operation of circuit breaker will be smoothly operate. The operator gave three chances for incorrect password otherwise message will appear on the LCD display for security purposed. It also sent the message control room regarding unauthorized access to the system.

Introduction

I. INTRODUCTION

The purposed of circuit breakers to protect electrical circuits from damage due to overloads or short circuits in Electrical system. The main feature of circuit breaker is to detect faults and block current flow. [4] [5]

The fuses are easily replace and circuit breakers can be reset (manually or automatically). Due to lack of communication and coordination between maintenance and substation personnel, the ratio of fatal electrical accidents of linemen are more in manual operation. To avoid such incidents, Circuit breakers can be designed using a password [6] [7].The operation of password circuit breakers can be design and fully controlled by an 8-bit microcontroller from the ATmega328P family. The password is stored inside the microcontroller under EEPROM and password can changed any time during operation and stored in microcontroller [8][9]. The keypad is used for entering the password and circuit breaker operation. If you enter the incorrect password the buzzer will sound an alarm [10] [11].

In the proposed system, circuit breakers control of the wire is assigned to the line operator. The project is designed not only for lineman safety but also maintenance point of view. If a fault occurs in a system, lineman enters the password to turn off the power supplied to the line, repairs the system comfortably.

II. LITERATURE SURVEY

Research work related to Smart Safety with Password Based GSM Module Controlling Circuit Breaker were studied and reviewed.

1. Mr. Tarun Naruka, Vivek Kumar Sharma, Vikram Singh, Vishnu Sharma reviewed in paper title “Password Based Circuit Breaker” that to control the circuit breaker, only specified password used and also provision of changing the password. For the program memory, 8 bit microcontroller 8051 family which has an 8KB of ROM is used for controlling. For password entering matrix keypad is interfaced to the microcontroller and relay IC driver is used to switch the loads through relays. Step down transformer (230/12V), is used to down the voltage to 12V AC and is converted to DC using a Bridge rectifier with capacitive filter for removed ripples. The voltage regulator (+5V) is used for microcontroller and other components [1]
2. Athira P Nair, Josephin J, reviewed in paper title “Electric line man safety system with OTP based circuit breaker” of International Journal of research in Engineering and Technology that for lineman safety while working, sudden electric shock do not feel. The chances of critical accidents are already very high due to live wires and poor coordination between lineman and substation. This paper give the solution for safety of maintenance staff and the lineman detect the fault in the electric line by SMS will be sent to the substation staff for switch off /on the line and  fully operated on a microcontroller [2]
3. Bhagwan Kharat, Durvankur Sarwade reviewed in paper title “Internet of Thing (I.O.T) Base Controlling & Monitoring of Circuit Breaker that modern control centres system operators get alarm messages from many devices in real time. From alarms, it is still very hard to find out location and type of the potential equipment problem. One needs an automatic way of processing the events to identify whether sequences of equipment operation were as expected. Instead of many alarm messages, only one report should be sent to the operators with concise information about success or failure of a switching sequence. In the case of breaker, report will offer more detailed message whether the breaker failure logic worked out properly and finally disconnected faulted section. This kind of analysis enables tracking of every CB operation allowing reconstruction of an entire sequence of operations. In our project we studied designed to attain real time control &monitoring of Circuit Breaker. Measure and record loading of your output of C.B and prevent overloading & increasing whole system life [3].

1. Preventing Unauthorized Access and Accidental Activation of Circuit Breakers: Mitigate risks of electrical hazards and ensure safe working conditions for personnel.
2. Enhancing Safety for line Workers During Maintenance: Ensure circuit breakers remain deactivated until workers complete tasks, reducing the risk of electrical shocks or injuries.
3. Protecting Sensitive Equipment and Systems from Unauthorized Tampering: Secure critical infrastructure and prevent potential damage or disruptions.

IV. OBJECTIVES OF PROJECT

The objectives of the project are:

1. Enhanced Security: Prevent unauthorized access to the circuit breaker by requiring a password for control. Protect against tampering and accidental activation, especially in hazardous environments. Improve electrical safety for personnel working on electrical systems.
2. Remote Control: Enable remote operation of the circuit breaker from any location with GSM coverage. Facilitate troubleshooting, maintenance, and load management without requiring physical presence. Offer flexibility and convenience for users.
3. Real-Time Monitoring: Track the status of the circuit breaker (on/off) in real-time. Receive alerts for unauthorized access attempts or abnormal conditions. Implement preventive measures and prompt responses to potential issues.
4. Cost Reduction: Minimize the need for manual intervention and site visits for control and monitoring. Reduce travel expenses and optimize resource allocation.
5. System Integration: Integrate the circuit breaker control with other systems or devices (e.g., home automation, building management).Foster a more comprehensive and interconnected smart environment.

V. METHODOLOGY

A. Existing Methods

In existing method, lineman need to visit power station and inform the in charge to ON/ OFF. Then station in charge can be the inform to station operator and after the official procedure the line will be ON/OFF. But these method was so old. there are the after latest technology give the password base method or finger finger prints scanner method so different types of method to operated but sometime loss connectivity lost signal or unskilled worker through likely not properly communicating so propose system give surety of controlling circuit breaker fully security based ON/OFF.

B. Proposed Methodology

The proposed system methodology provides a solution to ensure worker and safety. Lineman. Line ON/OFF control is performed only by the line operator.

This system is designed to require a password to control the circuit breaker ON/OFF. The lineman can switch off the power and make repairs comfortably, and can also turn the line back on by entering the correct password after returning to the substation. Since you can change your password, you can set your desired password and work more safely. In the proposed system, control (ON/OFF) of the wire is assigned to the line operator.

The project is designed in such a way that maintenance personnel or linemen must enter a password to turn the wire on or off. Now, if there is a problem with the wire, the lineman enters the password to cut off the power supplied to the line and repairs the line comfortably. When the lineman arrives at the substation, the lineman supplies power to the line. Specific line. This project uses a 4x3 keyboard to enter the password. Compare the entered password with the preset password. If the entered password is correct, the corresponding wire will turn on or off. In this project, each wire has a separate password. Switching on and off a line (circuit breaker) is represented by a load.

VII. FUTURE SCOPE

Integration of the SCADA system with the line will streamline fault detection and realization, enabling the lineman to promptly disable the faulty line using the circuit breaker. Additionally, incorporating a GSM module will allow for automatic SMS alerts to be sent to the workstation in case of line failure, facilitating a faster response time for the repair process.

Conclusion

This paper focus on Smart safety with password based GSM module controlling circuit breaker. Serious electrical accidents occurs becoming increasingly, when repairing power lines. It is happen due to lack of communication and coordination between maintenance and substation personnel. In the proposed system, the on and off line turning operation with the lineman to ensure the safety of linemen. For that, a secure password is required to operate the breaker operation and maintenance point of view.
