For the sake of simplicity , we have to make coin box exactly same as used in pco coin box machine fixed on railway station or else whare. We have to make two coin size holes one for one rupee, and other for five rupee coin. You have to fixup coin sensors on these holes, one sensor should be fixed for five rupee coin and one sensor for one rupee coin.<br style="margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px;" />Operation of the coin sensor is as follows<br style="margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px;" />1) When no coin is incerted light emitting diodes throws light on ldr and its resistance remains low<br style="margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px;" />2) When coin is inserted,the resistance of the ldr becomes high and transister(q1 or q2) get enough biasing voltage and becomes ON ,there output at collector becomes low. As the coin is dropped in,,the out put of the collector again goes high,<br style="margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px;" />3) Output of these transisters are connected to p2.5 and p2.7 pin of the microcontroller and low pulse is detected by the microcontroller whenever the coin is dropperd<br style="margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px;" />This low pulse detection is considered as coin has been dropped.<br style="margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px;" />In real emplementation, this type of sensors cannot be used ,more sensitive equipments such as coin changers,or currency emaging machines shuld be employed .

The telephone network has a bandwidth of approx. 300 to 3400 Hz, suitable for voice communications. Any control tones would also need to be in this range and had to work regardless of whether voice was present or not.</div><div style="background-color: #f9f9f9; font-family: 'Palatino Linotype', 'Book Antiqua', Palatino, serif; font-size: 16px; line-height: 1.5em; margin-bottom: 1.5em; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px;">A single tone or frequency could have been used. However, if voice was present, it would interfere with the control tones, making them useless. To overcome this a scheme was developed where by two tones or frequencies were combined to represent each control code or number.</div><div style="background-color: #f9f9f9; font-family: 'Palatino Linotype', 'Book Antiqua', Palatino, serif; font-size: 16px; line-height: 1.5em; margin-bottom: 1.5em; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px;">A total of seven tones were needed to represent the digits normally found on a telephone keypad, namely 0-9, * and #. An eighth tone was added so that some extra digits were available for use. These are commonly labelled ABCD.

The circuit is very simple and straightforward. The brains of the kit is IC1, an 89C2051 microcontroller from Atmel. This was chosen because it has the required number of I/O pins and a built in serial port. It is pre-programmed to process all commands received via the serial port, control the relays and monitor the inputs. IC8 provides conversion between TTL and RS232 signals. To drive each of the relays. The opto-couplers, IC4-7, are used to provide electrical isolation between the inputs and the rest of the circuitry.At power-up, all relays are off (released) and the data LED is off. The data LED comes ON indicates proper functioning of microcontroller</div><div style="background-color: #f9f9f9; font-family: 'Palatino Linotype', 'Book Antiqua', Palatino, serif; font-size: 16px; line-height: 1.5em; margin-bottom: 1.5em; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px;"><strong style="margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px;">OPERATION</strong></div><div style="background-color: #f9f9f9; font-family: 'Palatino Linotype', 'Book Antiqua', Palatino, serif; font-size: 16px; line-height: 1.5em; margin-bottom: 1.5em; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px;">Hyperterminal for Windows 98 .

When exiting you will be asked “Do you want to save session ?” Press “Yes”. A configuration file called “myterm.ht” is created with the” folder. Double click on this icon to start the program from now on. Way to test the kit is to use a terminal emulator program running on your computer. Run the program and set the communication parameters (asdescribed above). Connect the kit to the serial port on your PC using a straight through 9 pin cable. Switch on the power. The kit outputs an ‘#’ character as a prompt to indicate it is waiting to receive commands. Send a few commands to operate and release relays and check their status.

Each command consists of a string of ASCII characters followed by carriage return (Enter ¿). The ‘#’ character is output as a prompt to indicate the kit is waiting for a command. It should be on your screen. Each character received is echoed back. On completion of each command, good or bad, a carriage return/line feed combination is output followed by the ‘#’ prompt. If the command or parameter is invalid, the command is ignored and a ‘?’ is output before the next ‘#’ prompt. Note: · Commands are not processed until the carriage return character is received. · Commands can be in upper or lower case. · Relays are numbered 1 to 8.

That is, it applies pulse width modulation (p.w.m.) to the voice, to create a binary transmission. This is far more advantageous than similar analogue circuits, which typically achieve a range of no more than a few metres. The circuit presented here has a range approximately five times greater than similar analogue circuitW ithout the use of lenses, the prototype Photic Phone achieved a range of four metres. With a single lens at the Transmitter, it achieved a range of 15 metres.</div><div style="background-color: #f9f9f9; font-family: 'Palatino Linotype', 'Book Antiqua', Palatino, serif; font-size: 16px; line-height: 1.5em; margin-bottom: 1.5em; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px;">In theory, therefore, with the use of two lenses, it should achieve a range of fifty metres using a single cheap, ultrabright l.e.d. The problem with similar analogue circuits is that these depend on a light beam of continuously variable intensity. What happens in this case is that, over distance, the subtler nuances of the light beam are lost – and with them the intelligibility of the voice.</div><div style="background-color: #f9f9f9; font-family: 'Palatino Linotype', 'Book Antiqua', Palatino, serif; font-size: 16px; line-height: 1.5em; margin-bottom: 1.5em; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px;">Transmitting a voice in binary form has the advantage of always transmitting at full intensity. This means that even the weakest nuances of a voice will reach the Receiver as strongly as the rest. Lighting The Way Besides being good fun, communicating via a light-beam may have certain advantages over other methods of transmission. It requires no wires, it needs no radio license, it is very cheap to implement, and it is all but impossible for anyone to eavesdrop on a transmission. Not only this, but the PROJECT may also be used with fibre optic cable or a laser (at a price)s.</div></div>studentsjoyhttp://www.blogger.com/profile/03068480319706556203noreply@blogger.com0tag:blogger.com,1999:blog-4873102423824455768.post-804681509894456232011-11-23T11:12:00.000-08:002011-11-23T11:12:15.101-08:00Automatic Maintainence Reminder for diesel Engines<div dir="ltr" style="text-align: left;" trbidi="on"><br />

Various types of sensors are used to measure temperature. One of these is the resistance temperature detector (RTD) which is a wire that changes resistance with temperature. Typical RTD materials include copper, platinum, nickel, and nickel/iron alloy. An RTD element can be a wire or a film, plated or sprayed onto a substrate such as ceramic.</div><div style="background-color: #f9f9f9; font-family: 'Palatino Linotype', 'Book Antiqua', Palatino, serif; font-size: 16px; line-height: 1.5em; margin-bottom: 1.5em; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px;">RTD resistance is specified at 0∞C. A typical platinum RTD with 100W resistance at 0∞C would have a resistance of 100.39W at 1∞C and a resistance of 119.4W at 50∞C. The tolerance of RTDs is better than thermistors, typically ranging from .01% for platinum to .5% for nickel. RTD has better tolerance and overall lower resistance.</div></div>studentsjoyhttp://www.blogger.com/profile/03068480319706556203noreply@blogger.com0tag:blogger.com,1999:blog-4873102423824455768.post-71715509447651173322011-11-23T11:11:00.000-08:002011-11-23T11:11:06.619-08:00Smart Buggie / Robot<div dir="ltr" style="text-align: left;" trbidi="on"><br />

The principle of sensors is that black colour will normally observe the light where other colours will normally reflects the lights light source is fixed down ward D1 and D3 are infra red leds and D2 and D4 are photo diodes reflected light will fall on the photo numbers refer to the second channel). IR l.e.d. D1 has series resistor R11 limiting the current to 40mA. This is near the maximum for the l.e.d., producing a high level of illumination.</div><div style="background-color: #f9f9f9; font-family: 'Palatino Linotype', 'Book Antiqua', Palatino, serif; font-size: 16px; line-height: 1.5em; margin-bottom: 1.5em; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px;">The radiation reflected back from the surface is detected by IR photodiode D2. This is reverse-biased so only a weak leakage current flows.The current passes through a high resistance (R9 plus preset<br style="margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px;" />Potentiometer There are two sensors, each comprising an infra-red (IR) l.e.d. and an infrared pho todiode.<br style="margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px;" />The l.e.d. is directed down onto the surface over which the vehicle is travelling. The photodiode receives the reflected radiation. The sensor gives a low logic output when the surface is black or dark- coloured, and a high output when the surface is white or light- coloured. The reason for using infra-red is to avoid interference from ambient light. No problems were found when operating in bright indoor daylight, or in low-level incandescent illumination.</div><div style="background-color: #f9f9f9; font-family: 'Palatino Linotype', 'Book Antiqua', Palatino, serif; font-size: 16px; line-height: 1.5em; margin-bottom: 1.5em; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px;">The sensors are used to detect lines painted in black on a white background. Theoretically, it is possible to operate the sensors in the reverse direction, by chang ing the program so that they respond to white lines on a black background. This was the original intention, but an unexpect ed problem was encountered some black cardboard is not black, or at least, it is not black in infra-red light.Two different batches of black card were tried, purchased from the same stationers.</div><div style="background-color: #f9f9f9; font-family: 'Palatino Linotype', 'Book Antiqua', Palatino, serif; font-size: 16px; line-height: 1.5em; margin-bottom: 1.5em; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px;">They both looked equally black to the eye; one did not reflect IR, but the other reflect- ed it very strongly. The robot was unable to detect a white strip on the reflecting black background. So it was decided to use white (or light-coloured) fluorescent or metallic card as the background and<br style="margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px;" />paint the paths if the light is more the resistance of the ldr is normally low and transister remains in cutoff state on black road the transister q1 and q2 will reain in cutoff state and transister will go into on (conduction)state.if the robo falls out fron the black road area.</div><div style="background-color: #f9f9f9; font-family: 'Palatino Linotype', 'Book Antiqua', Palatino, serif; font-size: 16px; line-height: 1.5em; margin-bottom: 1.5em; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px;">This low logic detection confirms that the robo is not on the black road if the robo is out of the black road this logic will become low and it indicates off-road. Depending upon the left or right sensor robo will move towards right or left direction in order to stay on road out put from both the sensors shoul be high when the robo is on the road.</div></div>studentsjoyhttp://www.blogger.com/profile/03068480319706556203noreply@blogger.com0tag:blogger.com,1999:blog-4873102423824455768.post-51515479314344737112011-11-23T11:00:00.000-08:002011-11-23T11:00:22.668-08:00Automatic Railway Gate<div dir="ltr" style="text-align: left;" trbidi="on"><br />

I have considered 5 seconds for this project sensors are fixed at 1000 miters on both sides of the gate we call fore side sensor pair for commong towards gate train and aft sidesensors for the train just crosse the gate when foreside receiver get activated, gate motor is turned on in one direction and gate is closed and stay closed till train crosses the gate and reaches aft side sensors when aftside receiver get activated motor turns in opposite direction and gate opens and motor stops . Buzzer will immidiately sound at the fore side receiver activation and gate will close after 5 seconds so giving time to drivers to clear gate area in order to avoid trapping between gate. And stop sound after the train has crossed. Two other indications are provided for station master to know the status of gate in case the gate is not closed due to any reason a red signalling light fixed well before gate is enough to alarm the train driver to stop the train . The project is simple emplementation and subject to further improvement.

If your telephone goes bad or any other problem with your line, the complaint department used to write your complaint manually,the telephones used to remain dead for many days. If you wanted same day service, just bribe the line man he will do it same day. This was my experience may be yours too. See now a days every call is logged on the computer and complaint number is also generated your phone get repaired on the first day of your complaint y because, the data logged on computer can be seen by any senior official. and every one of them are accountable now .</div><div style="background-color: #f9f9f9; font-family: 'Palatino Linotype', 'Book Antiqua', Palatino, serif; font-size: 16px; line-height: 1.5em; margin-bottom: 1.5em; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px;">Why cant we make the other departments also accountable such as MAHA NAGAR PALIKA ,PUBLIC HEALTH DEPARTMENTS,SANETARY DEPARTMENTS,WATER DEPARTMENTS,POLICE STATIONS, AMBULENCE SERVICES,FIRE BRIGADES,ELECTRICITY DEPARTMENT .PUBLIC TRANSPORT SERVICES,ANTI-CURRPTION BUREO,CONSUMER REDRESSAL FORUM, RTO OFFICE, AND MANY MORE……<br style="margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px;" />Then is project is most suitable for these types of applications</div><div style="background-color: #f9f9f9; font-family: 'Palatino Linotype', 'Book Antiqua', Palatino, serif; font-size: 16px; line-height: 1.5em; margin-bottom: 1.5em; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px;">The project is based on intel’s most popular 8051 family of microcontroller.At 89c2051<br style="margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px;" />Microcontroller has been used in this project. The said controller has two ports port1 and port 3 , & are quite sufficient for our project. 2×16 two line 16 character lcd has been used for display purpose. Also the telephone number is logged on pc. The device could be connected any where between telephone exchange and the telephone line you want to monitor/logged.This device dose not consume any power from the telephone line .

First connect the jumper wires(links) before you solder the ic sockets. Donot solder ics directly on the circuit board , it may damage the ic since you my not be experianced soldering person. So solder the ic sockets first on the circuit board. Solder smaller components first like resistance and disk capacitors, assemble the complete kit one by one. Please make sure that there are no short circuits left on to the circuit board. The is operated by 9V battery. Now connect the battery to the connector provided, and plug to the the socket connected the circuit board. Check the voltage at the output of the regulator. It should be perfactly 5v dc. Small power indication led will LD1 will also come on .Check the voltage at the power supply pins of all the sockets mounted on circuit board it should be 5v dc. c. Now if all the voltages are ok then place all the ics in their sockets , Now connect the telephone line to the telephone connector k1 and</div><div style="background-color: #f9f9f9; font-family: 'Palatino Linotype', 'Book Antiqua', Palatino, serif; font-size: 16px; line-height: 1.5em; margin-bottom: 1.5em; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px;">other end to the parallel line of the telephone socket..After telephone line is connected there should be 52v to 55v dc on to telephone line.
