1. INTRODUCTION

PBOT – Pc Based Object Tracer

Electronics playing a vital role in the modern world. Computer system have been

around for more than a decade and today they have are used to support stock trade

transaction, make travel arrangements, and managed bank accounts. Most today’s

surveillance and security equipment were developed in order to have a touch with modern

electronic system.

PBOT is relatively new idea aimed to integrate computer and wireless

communication we find number of wireless system in daily walk of life giving various types

information to administrators. All this can be implemented using wireless RF receiver and

transmitter module. Parallel port pins are used to communicate from host to target system.

As regard capability of this module, it can perform modulation using ASK, at the

reliable range of level.



2. OBJECTIVE

The main aim of our project is to achieve the wireless administrative system

interfaced to PC and also to achieve full duplex communication.



MOTIVATION

Wireless communication plays a vital role in the present communication

scenario. Software programming helps us to keep in touch with VB programming languages.

Thus this project helps to keep in touch with the latest technology.



PRINCIPLE

Wireless switching of motors is done using PC and wireless data communication

is achieved using RF modules. This modules use amplitude shift keying with frequency of

433 MHz.

Wireless transmissions of audio and video signals are performed using FM

modulation.

4.1 FRONT END

PARALLEL PORT:

Parallel port is a simple and inexpensive tool for building computer controlled

devices and projects. The simplicity and ease of programming makes parallel port popular in

electronics hobbyist world. The parallel port is often used in Computer controlled robots,

Atmel/PIC programmers, home automation, etc... Here a simple tutorial on parallel port

interfacing and programming with some examples.

Everybody knows what is parallel port, where it can be found, and for what it is being

used. the primary use of parallel port is to connect printers to computer and is specifically

designed for this purpose. Thus it is often called as printer Port or Centronics port (this name

came from a popular printer manufacturing company 'Centronics' who devised some

standards for parallel port). You can see the parallel port connector in the rear panel of your

PC. It is a 25 pin female (DB25) connector (to which printer is connected). On almost all the

PCs only one parallel port is present, but you can add more by buying and inserting ISA/PCI

parallel port cards

PINOUT:

Figure 4.1.1



HARDWARE:

The lines in DB25 connector are divided in to three groups, they are

1. Data lines (data bus)

2. Control lines

3. Status lines

As the name refers, data is transferred over data lines, Control lines are used to

control the peripheral and of course, the peripheral returns status signals back computer

through Status lines. These lines are connected to Data, Control and Status registers

internally. The details of parallel port signal lines are given below.

PARALLEL PORT REGISTERS:

The registers found in standard parallel port are,

1. Data register

2. Status register

3. Control register

As there names specifies, Data register is connected to Data lines, Control register is

connected to control lines and Status register is connected to Status lines. (Here the word

connection does not mean that there is some physical connection between data/control/status

lines. The registers are virtually connected to the corresponding lines.). So what ever you

write to these registers, will appear in corresponding lines as voltages, Of course, you can

measure it with a multimeter. And What ever you give to Parallel port as voltages can be read

from these registers (with some restrictions). For example, if we write '1' to Data register, the

line Data0 will be driven to +5v. Just like this, we can programmatically turn on and off any

of the data lines and Control lines.



WHERE THESE REGISTERS ARE?

We have to find these addresses to work with parallel port. For a typical PC, the base

address of LPT1 is 0x378 and of LPT2 is 0x278. The data register resides at this base

address, status register at baseaddress +1 and the control register is at baseaddress + 2. So

once we have the base address, we can calculate the address of each registers in this manner.

The table below shows the register addresses of LPT1 and LPT2.

REGISTER LPT1 LPT2

Data Register (base address + 0) 0x378 0x278

Status Register (base address + 0) 0x379 0x279

Control Register (base address + 0) 0x37a 0x27a

PARALLEL TO SERIAL CONVERTER

FUNCTIONAL DESCRIPTION OF HT12E:

In this project wireless serial communication is used for transmission, so HT12E IC is

used to convert the parallel data to serial data before the actual transmission.

The 2 12 series of encoders begin a 4-word transmission cycle upon receipt of a

transmission enable (TE for the HT12E or D8~D11 for the HT12A, active low). This cycle

will repeat itself as long as the transmission enable (TE or D8~D11) is held low. Once the

transmission enable returns high the encoder output completes its final cycle and then stops.

ADDRESS/DATA PROGRAMMING (PRESET):

The status of each address/data pin can be individually pre-set to logic _high_ or

_low_. If a transmission- enable signal is applied, the encoder scans and transmits the status

of the 12 bits of address/ data serially in the order A0 to AD11 for the HT12E encoder and

A0 to D11 for the HT12A encoder. During information transmission these bits are

transmitted with a preceding synchronization bit. If the trigger signal is not applied, the chip

enters the standby mode and consumes a reduced current of less than 1_A for a supply

voltage of 5V.

ADDRESS/DATA SEQUENCE

The following provides the address/data sequence table for various models of the 2 12

series of encoders. The correct device should be selected according to the individual address

and data requirements.

ADDRESS/DATA BITS:

0 1 2 3 4 5 6 7 8 9 10 11

HT12E A0 A1 A2 A3 A4 A5 A6 A7 AD8 AD9 AD10 AD11



TRANSMISSION ENABLE:

For the HT12E encoders, transmission is enabled by applying a low signal to the TE

pin. For theHT12A encoders, transmission is enabled by applying a low signal to one of the

data pins D8~D11.

FLOW CHART OF HT12E:

TE is the transmission enable of the HT12E.

RF TRANSMITTER

TRANSMITTER GENERAL DESCRIPTION:

TX01 is transmitter with amplitude shift scheme with frequency range of 315 to 433

MHZ. ST-TX01-ASK is a hybrid transmitter module, with a low cost, small size and simple

to use for designing. It is biased with the supply range of 3 to 12 volt. Output power of

4-16dBm. By using TX01 200 to 3Kbps is achieved.

AMPLITUDE SHIFT KEYING:

ASK signal may be generated by simply applying the incoming binary data and the

sinusoidal carrier to the two inputs of a product modulator. The resulting output will be the

ASK waveform. ASK signal is basically the product of the binary sequence and the carrier

signal has power spectral density same as that of the base band on-off signal but shifted in

the frequency domain by ±fc. The spectrum of ASK shows that it has infinite bandwidth, it

is been proved that bandwidth of ASK is reduced by using smoothed versions of the pulse

waveform instead of rectangular pulse waveform.

TRANSMITTER MODULE

Figure 4.1.3



TV TUNER CARD

With help of the TV Tuner card we can give video and audio input to the personal

computer and also we can able to see the TV by giving cable or antenna wire to the card.

This TV Tuner card is connected to the PC with the USB port and audio out from the card we

want connect to the audio input jack which is at back panel of the system, Jack colored blue

in color.

Video which is transmitting by camera will be received through wireless receiver

that output will be given to TV Tuner card to get the video and audio in the PC using PBOT

software.

MICROPHONE:

With using the microphone we can able to generate the audio signal. So Mic wants to

be connected to the computer Mic-In audio jack which is colored red. Whatever the

administrator want to give information to subordinates he can speech in the microphone.

FM TRANSMITTER:

Frequency Modulation is the modulation technique which is used for sending voice

signal for a particular distance.

Here in this project we used this FM transmitter to transmit the voice signal because

the quality of voice signal in this modulation is high.

In this we can able to set the frequency for the voice signal which is to be transmitted.



4.2 TARGET SYSTEM (CAR) DESCRIPTION

RF RECEIVER:

ST-RX04-ASK is a superset receiver module with PLL synthesizer and crystal

oscillator, receiver frequency is from 315-433MHz. Typical sensitivity of receiver is

105dBm, with the input bias current of 2.3mA. The receiver is low power consumption, easy

for application, with on chip PLL using crystal oscillator reference. An RX04 include IF and

data filters, so external filter section is required.

AMPLITUDE SHIFT KEYING:

ASK signal may be generated by simply applying the incoming binary data and the

sinusoidal carrier to the two inputs of a product modulator. The resulting output will be the

ASK waveform. ASK signal is basically the product of the binary sequence and the carrier

signal has power spectral density same as that of the base band on-off signal but shifted in

the frequency domain by ±fc. The spectrum of ASK shows that it has infinite bandwidth, it

is been proved that bandwidth of ASK is reduced by using smoothed versions of the pulse

waveform instead of rectangular pulse waveform.

SERIAL TO PARALLEL CONVERTOR

Functional description HT12D:

The 2 12 series of decoders provides various combinations of addresses and data pins

in different packages so as to pair with the 2 12 series of encoders. The decoders receive data

that are transmitted by an encoder and interpret the first N bits of code period as addresses

and the last 12_N bits as data, where N is the address code number. A signal on the DIN pin

activates the oscillator which in turn decodes the incoming address and data. The decoders

will then check the received

Address three times continuously. If the received address codes all match the contents of the

decoders local address, the 12_N bits of data are decoded to activate the output pins and the

VT pin is set high to indicate a valid transmission. This will last unless the address code is

incorrect or no signal is received.

The output of the VT pin is high only when the transmission is valid. Otherwise it is always

low.

OUTPUT TYPE:

Of the 2 12 series of decoders, the HT12F has no data output pin but its VT pin can

be used as a momentary data output. The HT12D, on the other hand, provides 4 latch type

data pins whose data remain unchanged until new data are received.



FLOWCHART OF HT12D:

The oscillator is disabled in the standby state and activated when a logic _high_

signal applies to the DIN pin. That is to say, the DIN should be kept low if there is no signal

input.

Figure 4.2.2



MOTOR SWITCHING

LM293:

It is Push-Pull Four Channel Driver IC. This IC can able to drive two dc motor. It is

a monolithic IC which able to handle 600mA of current maximum per motor and also it

provide 1.2A of output current with non repetitive per channel.

This IC needed only 5v to close the switch and to open 0v and the switch can able to

withstand up to 120v. So this IC needed two supplies one is for switching as per the input

and another supply is for driving the motor.

It has internal clamp diode to the protect the switch from the back EMF produced

from the inductive load like dc motor.

Figure 4.2.3



CCTV CAMERA DESCRIPTION

The closed circuit television (CCTV) system issued on orbit to provide support to

orbiter and payload activities. This support includes transmitting real-time and recorded

video from the orbiter to MCC through either the S-band FM or Ku-band communications

systems. Mission requirements for CCTV and camera configurations are specified in the

Flight Requirements Document for each shuttle flight. The CCTV system consists of video

processing equipment, TV cameras (and lens assemblies), pan/tilt units (PTUs), camcorders,

video tape recorders (VTRs), color television monitors (CTVMs), and all the cabling and

accessories required to make these components work together. All CCTV operations can be

controlled by the crew. Most CCTV configuration commands can be executed by the

Instrumentation and Communications Officer (INCO) at Mission Control. Among the

commands MCCann uplink are those to configure and operate loose CCTV equipment, such

as camcorders and VTRs, and selection of inputs to the color monitors. Standard CCTV

components are powered via circuit breakers located on panel R14. Flight specific keel

cameras (prox ops or berthing) are usually powered from a cabin payload bus.

CCTV pushbuttons on panel A7U have lights that illuminate to provide visual

feedback on camera and CCTV routing configuration. These lights are powered via the

ANNUNCIATOR light switches located on panel A6U.



FM RECEIVER

Frequency Modulation is the modulation technique which is used for sending voice

signal for a particular distance.

Here in this project we used this FM receiver to receive the voice signal which as

been transmitted by the FM transmitter is connected to PC. In this we can able to change the

frequency for the voice signal according to the frequency set in the transmitter.

FM receiver is a small compact one which can able to keep inside the small toy car

and we can set the volume and frequency.

In the project we had provided a separate FM receiver that we can able to connect to

the Public addressing system.

DEVELOPMENT OF PBOT PROGRAMME

ACCESSING OF PARALLEL PORT IN VB:

Here in order to access the parallel port in VB we have to call the .DLL

files to the vb . Not all the DLL files are used, the DLL files which is used to configure the

parallel port is being called to the programme. The name of DLL file which is used to

configure the parallel port is INPOUT16.DLL else INPOUT32.DLL either can be called

according to application. 16 and 32 represents number of bits.

INPOUT32.DLL:

The functions in the DLL are implemented in two source files, "inpout32drv.cpp"

and "osversion.cpp". osversion.cpp checks the version of operating system.

"inpout32drv.cpp" does installing the kernel mode driver, loading it, writing/ reading parallel

port etc... The two functions exported from inpout32.dll are

1) Inp32 (), reads data from a specified parallel port register.

2) Out32 (), writes data to specified parallel port register.

\



The other functions implemented in Inpout32.dll are

1) DllMain (), called when DLL is loaded or unloaded. When the DLL is loaded, it

checks the OS version and loads hwinterface.sys if needed.

2) Close driver (), close the opened driver handle. called before unloading the driver

3) Open driver (), open a handle to hardware interface driver.

4) Inst (), Extract 'hwinterface.sys' from binary resource to 'system root\drivers'

directory and creates a service. This function is called when 'Open driver'

function fails to open a valid handle to 'hardware interface' service.

5) Start (), starts the hardware interface service using Service Control Manager

APIs.

6) System Version () Checks the OS version and returns appropriate code.



SOFTWARE SECTION

We utilized Visual Basic6.0 as software platform for our project, since it has IDE

(Integrated Development Environment) and also VB is a graphical user support, through

which we achieved the output graphical screen for our program without much complication.

VB has drag and drop option, hence programming is bit easier than C. The all that we need

timers to create proper delays in the program. VB has predefined timers, which is accessible.

In our project the role of VB program is, it checks the key press event in the keyboard, and

then it will generate particular ASCII value. The ASCII data generated will be sent to the

parallel port by accessing the inpout32.dll file. This file gives the address or the path to

access the parallel port.
