Abstract—With the increase in population and unemployment number of theft incidents have increased and most of the residential colony and organizations have gone with security option of having watchmen to guard them and their property when they are asleep. But how sincerely are they doing their duty or if they are sleeping for long time, are they alert at night? We are developing a system which will monitor the watchmen. The system generates an alert at random intervals and watchmen is supposed to react to it within an appropriate time, he can present himself to system with his RFID tag or his Finger print or a button press. If watchmen is not present then his absence is stored in the memory and at end of shift report is generated which can be viewed on LCD or sent as sms to supervisor or owner. In this project we want to build a product which will ensure that a watchman is doing his duty properly.

I. INTRODUCTION

Watchmen employing is a very essential aspect of an organization, be it an academic institutions and campuses or hospital complexes or industries (small scale or large scale) or shopping complexes and even in residential apartments or villas. In each and every field we require watchmen to guard the respective locality.

Is the sleeping watchman a familiar sight?

Watchmen's clocks and logbooks have not proven effective in improving the quality of patrols. One watchman, or indeed the entire watch-force out of action could mean very high losses.

Cameras help deter crime by signaling to perpetrators that they’re being watched and evidence is being collected against them combined with IP video surveillance management software and IP network cameras to deliver astonishing new benefits and capabilities to video surveillance — everything from centralized management and superior scalability to higher image quality and greater automation. But do they work effectively at night time? This is a serious drawback as far as cameras are concerned. Moreover cameras are not a cost effective solution for providing surveillance services when we require monitoring the watchmen performances.

Hence there has to be a system which effectively checks the status of the watchmen in the large campuses and

inform the supervisor the problem at any area if there is any lack in watchmen or security men activity which may lead to security breach.

Watchmen employing is very essential aspect of an organization, be it in academic institutions and campuses or hospital complexes or industries small scale or large scale or shopping complexes and even in residential apartments or villas.

II. BLOCK DIAGRAM

Block Diagram Description and Working

Most important part of the system is the alert generator which resides in the main microcontroller. It generates alert signal at random time. The minimum time gap and maximum time gap is programmable. Alert signals triggers light flasher which flashes light for 90secs to 120secs. The Watchman has to respond to this flashing light to acknowledge his presence. This can be done either by pressing button or showing a RFID card/Tag or putting his finger on Biometric finger print sensor.

If he fails to present himself in the allotted time, an absent is marked and stored in the EEPROM with time stamp. The time is read from RTC chip, both EEPROM and RTC chip are communicated using special protocol name I2C. At the end of shift all events are stored in EEPROM and report can be made and sent as sms to supervisor.

However two 15mins breaks can be given watchmen using break activate button. When he presses this button alerts are not generated for 15mins.

Modules Used in Realizing this system is explained : 16x2 LCD: It is the most common display system used in electronics and here we use to display product details, operations selections, final total etc.

RFID reader or Finger print scanner: Any one can be used to identified the watchmen/guard on duty and mark his presence. Once light is flashing watched/guard can prove his presence using his ID card (RFID based) or his finger. Both modules can be interfaced using UART to microcontroller. RFID reader is low cost and versatile whereas Finger print scanner is costly and delicate.

Real Time Clock: RTC chip to keep track of time, this chip keeps track of hh, mm, ss, dd, mm and yy perfectly with high accuracy. By using this microcontroller does not have to keep track of date and time.

Buzzer/ Alarm Signal: This is piezoelectric type of buzzer can be added during testing.

GSM Modem: To send reports to supervisor or manager, it is interfaced serially to microcontroller and AT commands will be used to control GSM modem.

Embedded Board: Main system which controls all of above, it consists of microcontroller capable enough to accomplish all task require for this product without any lags.

III. REQUIREMENTS

Hardware Requirements

1. Rugged long life Switches or RFID Reader with Tags or Finger Print Scanner

2. 16X2 LCD --- 1

3. MAX232 (RS232-TTL Convertor)

4. AT24C64 I2C Serial EEPROM From Atmel 5. DS1307 RTC from MAXIM

6. GSM Modem.

7. Embedded Board : P89V51RD2 Based or MSP430 based

8. RS232 Cables and FRC Cables 9. Leds, Buzzers and Switches

10. Jumper wires, hook-up wires, multi-stranded wires, Bread-Board, Soldering Iron etc.

Software Requirements

1. Uvision Keil to write, compile, debug and simulate embedded code.

2. HyperTerminal to interface to serial port and test various parts of project

3. Flash Magic for program downloading PC Requirements:

1. OS: WinXP SP2

2. CPU: Pentium 4 or higher 3. RAM: 512MB or higher 4. Hard Disk: 80GB or higher.

IV. ADVANTAGES AND DISADVANTAGES

Advantages:

1. Watchmen Monitor System Ensures that our watchman or guard is doing is duty properly and ourselves and our property is well guarded.

2. Button based system is very cheap and easily affordable by all levels in society.

3. Random generation of alerts ensures that watchman cannot predict next alert time hence he has to remain awake and alert.

4. All his attendance and not attendance are stored in EEPROM with time stamping. Which is use full for supervisor to analyze; same info is useful in making reports and sent as a message to the owner or supervisor.

Disadvantages:

1. Integrity of watchman duty and doubt on watchman can lead to humanity and social problem which can lead to disputes or oppositions from unions.

2. Initial installation cost is high, button system is the cheapest and biometric based is highest cost, SMS functionality is optional if added this also increases the cost.

3. In case of power failure system is not useful.

4. Watchmen may get stressed and demand more salary to respond to this system.

5. RFID can be retained by some other watchmen to cover the shifts of his friends and the same can be done by the others as well.

V. CONCLUSION

The system monitors the presence of watchman continuously by flashing the light at any random time and during that time the watchman has to put his RFID tag near the RFID sensor to register his presence. If he fails to do so absent will be marked and a report will be sent to supervisor.

It will be a very cost effective and safe as it is having high ability. It works continually without any problem.

Use of RFID cards to acknowledge is better than button press and Biometric acknowledge of random alerts is best and does not have loop hole. Embedded Email server can be added so instead of SMS daily, weekly and Monthly reports are sent as email to the supervisor.

VI . FUTURE SCOPE

1. System can be enhancing to optimize the patrolling coverage, frequency and alertness of watchmen during patrolling the premises.

2. Use of RFID cards to acknowledge is better than button press and Biometric acknowledge of random alerts is best and does not have loop holes.

3. Embedded e-mail server can be added so instead of sms; daily, weekly and Monthly reports are sent as email to the supervisor

4. A Complete in built battery with charging system can be added so in case of power outage system works seamlessly.

5. System can be used in schools/colleges to monitor the students and whether or not a particular student is present in class during class hours.
