Week 8

 BlOCK DIAGRAM OF THE PROJECT

Meeting Purpose:         To produce a block diagram for the automatic bottle filling machine
Meeting Date:               24/3/2021 (Wednesday)
Meeting Time:              9 P.M

Meeting Location:        MS Teams Platform

Meeting Facilitator:     Mohamad Saifullah bin Zolkefly

Attendees:                     Muhammad Firdaus bin Khaled, Muhammad Nasir bin Aziz.

Decision Made:

1. Types of Microcontroller to be used for replacing PLC

        - There are multiple types of microcontrollers that can be used to replacing PLC depends on the required operation. For example, Arduino microcontroller: Arduino UNO, Arduino Mega, Arduino Nano, Arduino Lily, Arduino Nano 33 IoT, etc. The Final decision made is by using Arduino Nano. 

2. Types of Microcontroller to be used for replacing PLC

        - The existing bottle filling machine comes with multiples designs for improving efficiency. For example, there are multiple designs of the assembly lines, conveyor systems, water tanks, filling nozzles and etc. The final decision made is to use two infrared sensors, a Wi-Fi module, a motor conveyor, and a water pump.

3. Block Diagram

Figure 1: Project block diagram.

Discussion:

    Figure 1 shows the finalized version of the block diagram used in this project. The input parts consist of 3 main components which are two IR sensors and one Wi-Fi Module. The first IR sensor is used to sense the presence of empty to stop the conveyor motor during the filling process. The second IR sensor used to count the complete yield produce after the filling process. The Wi-Fi module used to transfer the counting data to the Arduino IoT Cloud-based. Meanwhile, the selected MCU is the Arduino Nano which is responsible to execute all the programmed processes. Finally, at the output parts, there are 3 main components consist of a conveyor motor which is used to transport the bottles, the water pump which is used to pump the liquid for the filling process, and the IoT Cloud Blynk for yield monitoring purposes.

Conclusion:

In the conclusion, the outcome we get is able to finalize the project block diagram as well as gain our basic knowledge about multiples MCU that can be used as a PLC replacement in order to improve the existing process to the other such as monitoring using IoT.

Week 7

Meeting Purpose:       Tutorial exercises of voltage divider bias, CE BJT small-signal amplifier
Meeting Date:             19/3/2021 (Friday)
Meeting Time:             9.00PM
Meeting Location:       MS Teams Platform
Meeting Facilitator:    Muhammad Firdaus bin Khalid
Attendees:                    Mohamad Saifullah bin Zolkefly, Muhammad Nasir bin Aziz

Decision Made:

Discussion:

Voltage divider biasing configuration is the most widely used transistor biasing method. The emitter diode of the transistor is forward biased by the voltage value developed across resistor RB2. Also, voltage divider network biasing makes the transistor circuit independent of changes in beta as the biasing voltages set at the transistors base, emitter, and collector terminals are not dependent on external circuit values. To calculate the voltage developed across resistor RB2 and therefore the voltage applied to the base terminal we simply use the voltage divider formula for resistors in series.

We make a calculation to get the value of dc characteristics by using formula. To make sure the value of calculation is true so we construct the circuit of BJT small-signal amplifier in multisim and the result of IB, IC, IE and VCE almost same compare with calculation value.

Conclusion:

This week we know the how voltage divider bias is working. We also have learned how to calculate the dc & ac characteristics which is IB, IC, IE and VCE by using calculation and simulation.

Week 6

Meeting Purpose:         To determine the system requirements (what & why)
Meeting Date:               11/3/2021 (Thursday)
Meeting Time:              10.00PM
Meeting Location:        MS Teams Platform
Meeting Facilitator:     Muhammad Firdaus bin Khalid
Attendees:                     Mohamad Saifullah bin Zolkefly, Muhammad Nasir bin Aziz

Decision Made:

What:

• Change microcontroller PLC to Arduino
• Components and features added
• Choose automatic bottle filling machine

Why:

• Because Arduino is a latest technology can make the difficult concepts of programming and automation much easier to learn. It’s  also cheap compare to PLC.
• Selecting the appropriate components in line with the functions of the features added to the project, namely IoT module, IR sensor and 1 channel relay module.

Discussion:

We are thinking about wanting to replace the PLC to Arduino Nano on what machine. After discussing we chose an automatic bottle filling machine. We also added some of the latest features, namely the internet of things (IoT) for monitoring the machine from a smartphone.

Conclusion:

We have archive the innovation at the existing product to develop a product which is PLC replacement.

Week 5

Meeting Purpose:         To learn how to make a context diagram
Meeting Date:               3/3/2021 (Wednesday)
Meeting Time:              9.30PM
Meeting Location:        MS Teams Platform
Meeting Facilitator:     Muhammad Firdaus bin Khalid
Attendees:                     Mohamad Saifullah bin Zolkefly, Muhammad Nasir bin Aziz

Decision Made:

Discussion:

1. Users

• User enter the ingredient
• Users do finishing by packaging the bottles. 

      2. Maintainer

• Maintainer need to inspect the machine before and after process. If have any problem they need to change parts problem. 

      3. Energy source

• The machine use electrical energy to run the machine.
•  Thermal energy is used for boil.

     4. Control box (PLC)

• All the function of machine are control by control box.

Conclusion:

We have learned how to make a context diagram of mixture machine. We will use this information to make our project context diagram.
