ABSTRACT

An anti-theft system is any device or method used to prevent or deter the unauthorized

appropriation of items considered valuable. Nowadays, there are many cases about the

motorcycle theft happens in Malaysia. From the Royal Malaysia Police department motorcycle

theft cases increased each year. In 2010, a total of 1475 reported cases involving theft of cars,

motorcycles, vans and trucks while in 2011, a total of 2,086 cases were registered. Therefore

in this project it proposed to design anti-theft motorcycle alarm which is a system that can

prevent a motorcycle from being stolen. Alarm systems that have in the market nowadays are

very sensitive and make many false alarms. Also, the current system, use a vibrate sensor or

shock sensor as a main sensor. The false alarm will increase because if anyone touches the

motorcycle, the alarm will trigger easily even though they do not have any senses of stealing.

So, by doing this project, the motorcycle anti-theft system will reduce the false alarm as main

objective. To do so, first is a research about the alarm system for motorcycle was done. The

main component in the alarm circuit and sensor that will be used to achieve the objective was

studied. After that, the circuit was constructed and the testing was done to make sure the

system is running well. The Proteus software was used to simulate the circuit to see can the

circuit functioning well. In this project, Printed Circuit Board (PCB) design is used to develop

the circuit. In this motorcycle anti-theft system, the main sensor used is mercury tilt sensor.

This system will trigger when the mercury touch their two lids and the buzzer will ON. The

mercury tilt sensor will place on the motorcycle center stand. Then, the alarm will just trigger

when the stand is lift up. From this method, it will reduce the false alarm.

ABSTRAK

Sistem anti-kecurian adalah sebarang peranti atau kaedah yang digunakan untuk

mencegah atau menghalang kecurian daripada berlaku. Pada masa kini, terdapat banyak kes-

kes tentang kecurian motosikal yang berlaku di Malaysia. Oleh itu dalam projek ini, telah

dicadangkan untuk mereka bentuk satu sistem anti-kecurian penggera motosikal yang

merupakan sistem yang boleh menghalang motosikal daripada dicuri dengan mudah. Sistem

penggera yang ada dalam pasaran sekarang ini sangat sensitive. Selain itu, sistem penggera

motorsikal semasa menggunakan sensor getaran atau sensor kejutan sebagai sensor utama.

Penggera palsu akan meningkat kerana jika sesiapa menyentuh motosikal, penggera akan aktif

dengan mudah walaupun mereka tidak mempunyai apa-apa niat mencuri. Jadi, dengan

melakukan projek ini, sistem anti-kecurian motosikal akan mengurangkan penggera palsu

sebagai objektif utama. Untuk berbuat demikian, pertama sekali, kajian tentang sistem

penggera untuk motosikal telah dilakukan. Komponen utama dalam litar penggera dan sensor

yang akan digunakan untuk mencapai objektif telah dikaji. Selepas itu, litar itu dibina dan

ujian telah dilakukan untuk memastikan sistem ini berjalan dengan baik. Perisian Proteus telah

digunakan untuk mensimulasikan litar untuk melihat adakah litar tersebut boleh berfungsi

dengan baik. Dalam projek ini Printed Circuit Board (PCB) telah digunakan untuk membina

litar. Dalam sistem anti-kecurian motosikal ini, sensor utama adalah merkuri kecondongan

sensor. Sistem ini akan berfungsi apabila merkuri menyentuh dua kaki sensor itu dan

menyebabkan penggera berbunyi. Sensor merkuri itu akan ditempatkan pada dua kaki berdiri

motosikal, Kemudian, penggera hanya akan berbunyi apabila dua kaki berdiri motosikal

dialihkan daripada kedudukan asal. Dari kaedah yang dijalankan ini, ia akan dapat

mengurangkan penggera palsu.

CHAPTER 1

INTRODUCTION

1.1 Project Background

Nowadays so many cases about motorcycle being stolen occurred. There are many

kind of motorcycle alarm system that available in the market. Most of the alarm system use a

vibrate sensor or shock sensor as a main sensor. When using this both sensor the alarm system

become too sensitive because if anyone touches the motorcycle, the alarm will trigger easily

even though they do not have any senses of stealing.

By doing this project that using mercury tilt switch as the main sensor, it will trigger

the alarm when the motorcycle is lifted off its center-stand. Of course this kind of alarm

unable to catch the thief 100% but it prevents the motorcycle from being stolen easily.

This project will control the false alarm because it is not only about vibrate or just

touch the motorcycle, but it will trigger when the lid at mercury switch is contacted by the

mercury. This project, cover the application of mercury sensor, relay and transistor.

1.2 Objectives

The objectives of this project are: -

i. To design the anti-theft motorcycle alarm circuit.

ii. To simulate the circuit operation using Proteus software.

iii. To develop the prototype for the anti-theft motorcycle alarm.

1.3 Problem Statement

Nowadays, there are many cases about the motorcycle theft happens in Malaysia. From

the Royal Malaysia Police department motorcycle theft cases increased each year. In 2010, a

total of 1475 reported cases involving theft of cars, motorcycles, vans and trucks while in

2011, a total of 2,086 cases were registered. However, the first seven months of 2012, a total

of 832 cases have already been reported. [1] Negligence and carelessness identified as the

main causes of many of the cases of loss of motorcycle. Therefore in this project, it is

proposed to developed and constructed anti-theft motorcycle alarm to prevent this problem.

1.4 Project scope

Components such are mercury tilt switch, buzzer, relay, and transistor will be used to

develop the motorcycle anti-theft system. For the first step, the theory about this system

should be research. When all the components are ready, we will combine it in one circuit. The

alarm should be able to generate loud sound and trigger when the motorcycle is try to be

stolen.

CHAPTER 2

PROJECT BACKGROUND

2.0 Overview

In this chapter, there are some of point that will be review which is literature review aboutalarm system, previous system and technique and type of component used.

2.1 Literature review about alarm system

2.1.1 Anti-theft system

An anti-theft system is any device or method used to prevent or deter the unauthorized

appropriation of items considered valuable. Theft is one of the most common and oldest

criminal behaviors. From the invention of the first lock and key to the introduction of RFID

tags and biometric identification, anti-theft systems have evolved to match the introduction of

new inventions to society and the resulting theft of them by others.

Under normal circumstances, theft is prevented simply through the application and

social acceptance of property law. Ownership is often indicated by means of visual marking

(license plates, name tags). When clear owner identification is not possible and when there is a

lack of social observance, people may be inclined to take possession of items to their own

benefit at the expense of the original owner. Motive and opportunity are two enabling factors

for theft. Given that motives for theft are varied and complex and are generally speaking not


18/63

within the control of the victim, most methods of theft prevention rely on reducing

opportunities for theft. [2]

Items may require an anti-theft system for a variety of reasons, which may occur in

combination depending on the type of item and its use:

a. The item is expensive and/or has sentimental value (prestigious car, family heirloom,

birthday gift, war medals, coin collection)

b. The item is difficult/impossible to replace if lost (produced in low numbers, antiques, and

unique works of art)

c. The item is easy to steal (retail/supermarket products, office stationery, no security tags (TJ)

d. The item may be left unattended in an unsafe environment (laptops in a library, cars in a car

park)

e. Inappropriate use of the item may cause considerable damage or may enable further

unauthorized acts (theft of car keys, stolen building access keys, identity theft)

f. The item is desirable to others (jewelry, mobile phones, rare collectibles, auto parts,

industrial designs)

2.2 Previous system or technique

This section will represent the previous project or system that already developed which

is shock alarm circuit.

2.2.1 Shock Alarm Circuit

The Figure 2.1 is a shock sensitive alarm circuit that has many applications from home

to automobiles. The main application of this circuit is to use it as an anti-theft alarm in

automobiles. A piezoelectric sensor is used as the shock sensor which has to mount on the

door or at body which you have to protect.

Here the IC1 LM 3558 is wired as an inverting Schmitt Trigger. The POT R1 sets the

threshold voltage of the circuit.R1 is used as a feedback resistor. When not activated the

output from the piezo sensor will be low and so do the output of the IC. When the piezo sensor

is activated its output voltage goes high and triggers the Schmitt trigger. This results the

beeping of the buzzer. The buzzer remains beeping for some time even if the vibration is

removed, this is because the increase in the inverting input has little effect when the IC is

triggered and the state cannot be easily reversed. [3]

2.3.2 Transistor BC557

Transistors are widely used electronic components that perform the function of a

switch or an amplifier.

The properties of the transistor allow it to be used as a rectifier, allow current to flow

in only one direction. When the P side is made positive by an applied field, the barrier height

is lowered and most of the electrons from the N side flow to the P side and most of the holes

flow to the N side. The transistor is said to be forward biased in this case. When the applied

field makes the P side negative, the barrier height is increased and only a leakage current can

flow through the transistor. The transistor is said to be reverse biased in this case.

A transistor can also function as an amplifier. When a small input current is applied to

the base-emitter of a PNP transistor, it gets amplified and a larger current results in the

collector-emitter circuit. A typical application of a transistor as a vital electronic component is

in a radio wherein weak radio signals from an antenna are amplified into stronger signals

identifiable by human ear by a transistor. [5]

2.3.3 Relay 5V

A relay is an electrically operated switch. Many relays use an electromagnet to

mechanically operate a switch, but other operating principles are also used, such as solid-state

relays. Relays are used where it is necessary to control a circuit by a low-power signal (with

complete electrical isolation between control and controlled circuits), or where several circuits

must be controlled by one signal. The first relays were used in long distance telegraph circuits

as amplifiers: they repeated the signal coming in from one circuit and re-transmitted it on

another circuit. Relays were used extensively in telephone exchanges and early computers to

perform logical operations.

A simple electromagnetic relay consists of a coil of wire wrapped around a soft iron

core, an iron yoke which provides a low reluctance path for magnetic flux, a movable iron

armature, and one or more sets of contacts (there are two in the relay pictured). The armature

is hinged to the yoke and mechanically linked to one or more sets of moving contacts. It is

held in place by a spring so that when the relay is de-energized there is an air gap in the

magnetic circuit. In this condition, one of the two sets of contacts in the relay pictured is

closed, and the other set is open. Other relays may have more or fewer sets of contacts

depending on their function. The relay in the picture also has a wire connecting the armature

to the yoke. This ensures continuity of the circuit between the moving contacts on the

Figure 2.6: Relay 5V


24/63

10

armature, and the circuit track on the printed circuit board (PCB) via the yoke, which is

soldered to the PCB. [6]

When an electric current is passed through the coil it generates a magnetic field that

activates the armature and the consequent movement of the movable contact either makes or

breaks (depending upon construction) a connection with a fixed contact. If the set of contacts

was closed when the relay was de-energized, then the movement opens the contacts and

breaks the connection, and vice versa if the contacts were open. When the current to the coil is

switched off, the armature is returned by a force, approximately half as strong as the magnetic

force, to its relaxed position. Usually this force is provided by a spring, but gravity is also used

commonly in industrial motor starters. Most relays are manufactured to operate quickly. In a

low-voltage application this reduces noise; in a high voltage or current application it reduces

arcing.

When the coil is energized with direct current, a diode is often placed across the coil todissipate the energy from the collapsing magnetic field at deactivation, which would otherwise

generate a voltage spike dangerous to semiconductor circuit components. Some automotive

relays include a diode inside the relay case. Alternatively, a contact protection network

consisting of a capacitor and resistor in series may absorb the surge. If the coil is designed to

be energized with alternating current (AC), a small copper "shading ring" can be crimped to

Figure 2.7: How a relay works [7]


25/63

11

the end of the solenoid, creating a small out-of-phase current which increases the minimum

pull on the armature during the AC cycle.

A solid-state relay uses a thyristor or other solid-state switching device, activated by

the control signal, to switch the controlled load, instead of a solenoid. An optocoupler (a light-

emitting diode (LED) coupled with a photo transistor) can be used to isolate control and

controlled circuits. [7]

2.3.4 Buzzer

Buzzer is one of a transducer, which converts electrical energy to sound. This

transducer used for this project as an indicator for alarm system.

For the circuit operation when the circuit is receive the supply from battery, but if the

mercury tilt switch not trigger the alarm system will not turn on because the current cannot

flow through the circuit. But when the mercury tilt switch is trigger, the current will flow to

the transistor GATE (G) terminal and trigger the transistor. When the transistor trigger, relay

is energized to generate the buzzer and the alarm system will turn on.

3.4 Simulation of circuit design

Simulation is the imitation of the operation of real-world process or system over time.

Simulation can be used to show the eventual real effects of alternative conditions and courses

of action. It is also used when the real system cannot be engaged, because it may not be

accessible or it may be dangerous or unacceptable to engage or it is being designed but not yet

build or it may simply not exist.

To make a simulation for the circuit design, the Proteus software is used to see if the

circuit can function well. Using Proteus software the circuit design is apply at schematic

capture (ISIS) to see how the circuit works and to see if there is any error with the circuit

design. If the circuit can be operates well, after that the circuit is tested at project board. Figure

3.4 show the simulation of the circuit using Proteus software.

3.5 Printed Circuit Board (PCB Design)

After all the simulation and troubleshooting is done, the circuit will transform into

hardware form. In this project PCB Design is used developed the circuit.

3.5.1 How design the circuit into the Printed Circuit Board (PCB).

To construct the PCB design for the circuit, the ARES software is used. Ares software

is software that used to transform the circuit design into PCB layout. From schematic capture

(ISIS), the circuit is changed into PCB layout (ARES) to see the layout of circuit design in

PCB form. [8]

For every component in Proteus software, there is a component with packaging tool

and a few components not have it. Using packaging tool, user can see if the size and pin

number of component that used in schematic design is same with the component that user buy

for the circuit. If same, the process of PCB Design can be continuing. Components size in

PCB Design must be same as the real one to make the components fitted on the circuit that

will be printed.

The PCB design that has done will be printed on the glossy paper (photo paper) using

laser printer. This is because laser printer ink is made up from plastic material, and the design

we print will stick nicely at glossy paper. The procedure below show how to design the circuit

into the Printed Circuit Board (PCB).

In figure 4.2, it shows that, the key switch in normally-closed state, and current flow in

the circuit = 1.13A. Mercury tilt switch also in normally-closed state, it mean the sensor is

trigger. When the sensor is trigger the transistor also trigger. When the transistor trigger, relay

is energized to generate the buzzer. This show at output voltage = 11.9V.

4.1.2 Waveform of the simulation

CHAPTER 5

CONCLUSION AND RECOMMENDATION

5.0 Overview

In this chapter, all results have been discussed and conclusion has been made for the

whole project. All the conclusion and the recommendation for the future work will be

highlighted.

5.1 Conclusion

At the end of this Project Diploma, the objectives of the project have been achieved.

All the scopes already covered but still have many rooms to make the modification. While

completing this Anti-Theft Motorcycle Alarm, many new things and experience gained.

The circuit of Anti-Theft Motorcycle Alarm has been successfully designed after a few

researched about motorcycle alarm has been made. After the design of the circuit was

completed, the circuit is simulating using Proteus, the simulation was successfully done and

all the result and analysis has been discussed at Chapter 4. The simulation has been transferred

to the hardware implementation using Printed Circuit Board (PCB). The prototype of Anti-

Theft Motorcycle Alarm has been successfully developed.


50/63

36

Anti-Theft Motorcycle Alarm is very useful for motorcycle owner. This alarm will

prevent the motorcycle from being stolen easily. By using mercury tilt switch as the main

sensor, it will trigger the alarm when the motorcycle is lifted off its center-stand. Of course

this kind of alarm unable to catch the thief 100% but it prevents the motorcycle from being

stolen easily.

By using this alarm system, the many cases about the motorcycle theft can be prevent

and reduced.

5.2 Recommendation

As the recommendations for this project, the IC555 Timer can be added to make the

alarm automatically reset after a few moment. This system also can be upgraded with using

automatic immobilizer added to the anti-theft system. The automatic immobilizer is an

electronic security device fitted to an automobile that prevents the engine from running unless

the correct key (or other token) is present. This prevents the motorcycle from being "hot-

wired" after entry has been achieved.

At the end of this project, hopefully this system will be achieving the objective of the

project. This system can be commercialized as an Anti-theft system for motorcycle. This is

because of the cost to developed it is low and it can be implemented in any type of

motorcycle.
