ObjectiveIn order to achieve the urgent need in many industrial applications tothe possibility of controlling the opening and closing of the gates

controlling the ow of uids in general and a lot of security-relatedapplications or safety purposes or the purposes of pollutionprevention or the like So there must be very high in the process ofopening and closing the gate, a security element So we oer throughthis project a modest work aims to achieve the goal of.

:he aim of the project!chieving the process of opening and closing doors for industrialapplications through the use of a computer and by a particularprogram "et into your code to open the gate to be opened or isentering a special code closure process to be closed gate.

he purpose to clarify the idea of the project is the largest wedecided that we take, for e#ample, with industrial applications gates,gates own dams.

!s shown in the mass of the planned project, there is a pulse signalout of the computer after giving the closure order of the personauthori$ed user computer which gives it after the introduction of %I&

number to the program that was set up by a program visual studio,we therefore have to deal with this matter 'the closure of a pulse(through the electrical circuit of uranestor circle and is used here as akey electronic control of the process of feeding carryover )le '*elay(electric power, which in turn control the process run +ontektr )le,which is the process of control of the operation of the electric motor,which controls the opening and closing doors.

here is also a pulse open outside of the computer responsible forthe process of opening the gate and go through the sameaforementioned previous steps in the closing process.

It is what we have over the system?s work to clarify that the wholeprocess related to the entry of an electrical pulse from the computer,and certainly this impulse to be instantaneous5 his means we needto provide continuous operation for an operation to open or close thegate5 So it is secured through the operating line of continuitycompensation described in the control scheme through the point '( to'( here has been to clarify the system?s work completely and thissame process applies to the work of the system when opening and

closing doors.

components

-7S %arallel portsIs kind of the ports on the computer used to connect peripherals andmultiple devices is also known as a gateway printer called parallelbecause it transmits data unilateral bit parallel meaning it conveys

more than a bit at the same time, unlike the serial port that is nottransferred to only

one bit per minute

-4iode6lectronic cut con)ned its role to allow for electrical current to pass inonly one

direction.

-ransistorIs the crystalli$ation of semiconductor material inlaid germanium andsilicon has a very thin crystal so that the central region, including the

semi-positive or negative connector is called the base between thetwo regions of the e#ternal @uality oense and has a great ability toenlarge electronic signals.

here are two types of transistor in terms of polar &%& and %&% inelectrical circuit for the project will be the use of &%& type transistortaking advantage of one of the many characteristics of a transistor as

a key

-*esistanceIt is a physical property means intercept 'disability( material for thepassage of electrical charge through them5 *esistance occurs whenelectrons moving collide with atoms in the material and releaseenergy in the form of heat.

6lectrical resistance is measured in ohms and has the symbol 8 andsports law is

Ohm A 3olt ; !mpere

-*ecti)er!n electrical device that converts the ! signal to a continuous

stream5 It is commonly used in many electrical applications suchas electric charger electronic devices and sensors radio signal.

controlled by low voltage circuit, and both circles completely separatefrom each other.

an simply understand the action relay that are linked ovenants polesof magnets in the electric circuit with low voltages 'for e#ample, Cvolts( or, as we can tell them it?s the circuit controlling the high-voltageelectrical circuit5 =hen you pass the circuit controlling electricity thiselectromagnet, it simply becomes a magnet5 he function of thismagnet is to transform the connection path between the poles and& to and &O becomes poles and &O are connected with eachother.

-ontactorIs the heart of the control circuits 6lectrical :ost of the electricalcontrol circuits can not be designed without a contactor and

contactor works mainly on the eect of the magnetic electriccurrent so that it uses a )le is going through an electric currentgenerates a magnetic )eld attracts the heart of iron, which isconnected with the parties to the ability department usescontactor mainly in operation of devices and e@uipment, which is

characteri$ed by high voltage teams, as well as a large currentwhen operating such as factory machines, air conditioners circuitslighting, heating and others.

an be 4etailing a way to work the following steps:

1(he planting and installing electronic parts by welding to painting oo$e'panel electronic parts( where the ring was built electronic, of the transistorcircuit bene)ciaries of one of the characteristics of a transistor much work asthe key, It was then holding the connections between the parts and electronicwire and by then been connected wires to enter the electronic circuit and e#it

through the connecting bar and install it on the plate electronic parts.!fter the completion of the work the special panel installed electronic partswere installed inside the control panel.

2(=as installed circuit e@uipped with the ability '/2 3-45( feeding your e-electric power circuit inside the control panel also.

3(9ave been installed all electrical parts for the control circuit to operate theengine within the control panel and after the installation has been linked toparts by electrical wires were then connected wires to enter the ring control

of the engine and e#it through the delivery bar.

4(!fter the completion of the installation of all the parts in eachlocation we began by linking the electrical wires between the circuite@uipped with the ability '/2 3-45( and electronic circuit , and theelectronic circuit 'transistor circuit( and the 4epartment of the enginecontrol.

5(!fter the completion of the installation and the electricalconnection =e had a screening process through the feed system with
