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.
