Experiment of Trouble
shooting : Main Problem
Not all planning will be
end exactly well done. For this project, there were many of problem occurs
during the period from the start until the end. By making the investigation and
listed the problem occurs during the period.
- Wrong decision.
At the starting project, the current sensor using comparator op-amp was
chosen to sensing the current through the power windows. However in the
middle of the project, realize that the Acs756 is better to be used and
the configuration is written through the datasheet.
- H-bridge mosfet
with high current rating failure to operate due to the burn of the
transistor because of no heat sink used.
- Careless. This
problem is always face it during the period that use to finish hardware
part works. Not using any circuit protection make the circuit and relays
damage and burns due to high current and voltage spikes.
- Lack of resource.
Some of part in this project is hard to find the solution.
- The starting
current of the motor cannot be monitor due to limitation
of device or laboratory equipment that can measure the current in real
time.
Upon the completion of
the system, a test should be conducted to test the accuracy and the stability
of the system.
Conclusion
This
chapter has discussed about the result of this project and hard ware
development. In order to make this project successful, all these element have
recorded the result to make sure that it functions to make a quality process
according to need of the project objective. The real picture of hardware
development, PCB design, and assemble process are already attached. The
important stages in this chapter are trouble shooting the problems that faced.
This is because, to test the project circuit and collect the output result.
Results from circuit development will interface with program and compile it in
order to run this project smoothly.
CONCLUSION AND
RECOMMENDATION
Introduction
This
chapter discuss about the conclusion and suggestion in the future. This project
has two major parts which is hardware description and software implementation.
Both topics were very related and important to each other and can be applied to
perform the system more effective. This chapter is very important because it
helps to overcome the problem and improve the efficiency of the project.
The
overall summary can be made for this project is the entire objective for this
project is achieved. This project is actually will make a new evolution in
furniture industrial era. For these reason, it is important to develop methods
to show a different ways of marketing to popularize their products. It will
show that electric and electronic field has a lot of criteria to impose in
engineering section.
Conclusion
The
revolution of car technology have become drastically change and widely
practiced throughout the world. The development of power windows safety system becomes
a new technology that can be commercialized in the world. Actually this project
is a new solution for user that always wanted for technologies that will ease
their concerned of safety.
Nowadays, technologies are very advance.
Majority products that produce from manufacture are in automatic mode. So
basically this project is a new way to follow up the technologies. This new
development totally can save their energy by using this project.
Recommendation
The
performance of the system is can be increases so that this system will be more
up to date and more flexible. For future works, some recommendations have been
listed in order to improve the system performance
i.
Puts the program in
engine control unit (ECU) of the car to minimize the costing to use new
Microcontroller. Almost all of the ECU of the car can be reprogram and update
the system so that is more efficient.
ii.
For the next
improvement is protecting the microcontroller from the heat is very important the
microcontroller should be able to function efficiently. Therefore, microcontroller should be protected
as well as possible to avoid microcontroller exposed to extreme temperatures
and cause damage. . It is important to make the user feel comfortable and safe.
iii.
Then, for lastly is need to improve the program
and circuit so that the power windows can goes up and down automatically with 1
input from the user.
Summary
In this final year
project the power window looking forward in improving the design so that it is
more convenient to be used and have more safety. Therefore the basic operation
to improve the power windows is connecting the power window motor to the MCU.
When the power windows is stuck by something or have more loaded then usual the
MCU directing the motor to give a chance to remove the anything that disturbs
the windows before it closed. Other than that the time to service and put a
lube to the mechanical part will make the longer life time to the motor and
overall mechanism of the power window.
This development of the
project is reviews the various type and configuration of the power windows
systems which will be then to be used to test and validate the proposed
reliability estimation method.
This project involves hardware
and software parts construction and the integration of both parts to create the
system. In the end of this project, all the document, hardware and software
development and provide a simulation model of the system.
Through overall of the
project the procedure to test the circuit is need to be listed so that the
circuit is not damage. The damage of the circuit is costing lots of money and
wasting time during troubleshoot and testing.
