31 3.6.6.1 Create a launcher script 32 3.6.6.2 Make It Executable 32 3.6.6.3 Add Logs Directory 32 3.6.6.4 Add to Crontab 33 3.6.6.5 Reboot and See If It Works 33 CHAPTER 4: EXPERIMENT RESULT AND DISCUSSION 4.1 Result 34 34 4.1.1 Result overview 34 4.1.2 Image of real-life system 34 4.2 Discussion 34 4.2.3 Error Signal Detection 37 CHAPTER 5: CONCLUSION & FUTURE DEVELOPMENT 5.1 Conclusion REFERENCES 39 39 41 Bibliography 41 APPENDIS 42 ix 3.6.4 Prepare for CAN module First of all, CAN module needs to be connected with Raspberry Pi B4 After that, the student installs some libraries that need operation Then, the student config for system If the result is just like the following pictures, it means that CAN module is compatible with Figure 3.23: when CAN module connect success system After that, the student will connect the H and L port of RS485 CAN HAT to another subsystem 3.6.5 Prepare server for uploading data First, we need to create channel, then create many fields that will show data on it To collect data, the student had to copy channel links and API keys to deploy to program Figure 3.24: create new channel in thingspeak 3.6.6 How to run all of them whenever system boot up automatically? This is one of the most critical of system Normally, dashboard needs to boot everything automatically To solve this problem, the student has chosen a simple way, which is create a launcher script and run it automatically whenever Raspberry boost There are following steps that need to complete 31 3.6.6.1 Create a launcher script My python script is called: main.py and lives in a directory called main that is in the root directory We will use the Linux crontab to run the Python script The launcher script will look like the following picture Figure 3.25: Create a launcher script in Raspberry What this script will is to navigate to the root directory, then to the bbt directory, launch the Python script and then return to the root directory 3.6.6.2 Make It Executable We need to make the launcher script an executable, which we with this command: $ chmod 755 launcher.sh Now test it, by typing in: $ sh launcher.sh This should run the Python code 3.6.6.3 Add Logs Directory We will get to using crontab in a minute, but first we need to make a directory for the any errors in crontab to go Navigate back to home directory: $ cd Create a logs directory: $ mkdir logs 32 3.6.6.4 Add to Crontab Figure 3.26: add to crontab in raspberry Crontab is a background (daemon) process that lets you execute scripts at specific times It's essential to Python and Raspberry Pi The details are confusing, as is often the case with Linux Once I got the hang of the format, I've found it to be incredibly easy to use Type in: $ sudo crontab -e This will bring up a crontab window Now, enter the line: $ @reboot sh /home/pi/bbt/launcher.sh >/home/pi/logs/cronlog 2>&1 What this does is rather than executing the launcher script at a specific time, it will execute it once upon startup 3.6.6.5 Reboot and See If It Works Unplug the power or just type in: $ sudo reboot Wait for startup and see if your script automatically launches 33 CHAPTER 4: EXPERIMENT RESULT AND DISCUSSION 4.1 Result 4.1.1 Result overview Figure 4.1: overview of system 4.1.2 Image of real-life system Figure 2: real-life system's image 4.2 Discussion The performance test was repeated three times, and the device was run continuously for 12 hours The experiment was designed to examine the device's ability to operate for a period of time comparable to or greater than the operational time of an electric motorcycle Flowing the green rectangle to compare the data 34 First time: 21st June 2021| 12:28:00 PM: Figure 4.3: screenshot of terminal screen when receive CAN signal Figure 4.4: screenshot of dashboard These above images are the data that is read from sub-system at 22st June 2021| 00:28:00 PM Then the author left system and sub-system work for day continuously to test how consistence of the system was First time: 22st June 2021| 00:28:00 PM: 35 Figure 4.5: screenshot of terminal screen when receive CAN signal It can be seen from figure 33 that data sent to IoT platform was continuous and stable after the whole day It proves that system can work well with the mentioned scope Figure 4.6: screenshot of dashboard After day, system and sub-system still worked well, data was not interrupt and correct all the time I show that system meet the requirement of the mentioned objective 36 4.2.3 Error Signal Detection 180 160 140 120 100 80 60 40 20 13 19 25 31 37 43 49 55 61 67 73 79 85 91 97 103

break down time The author was record normal data and data with issue With these data, user can easier fix system when they met problem like this The data in figure 35 show normal data and the following data show how I would be when system got problem and which problem are normally happened to system 180 160 140 120 100 80 60 40 20 17 25 33 41 49 57 65 73 81 89 97 105 113 121 129 137 145

system at the moment it lost CANbus connection and kept updated after connection recovery COMMENT ● For each different case, the device receives and transmits exactly as required ● No problems with delay or mis-transmission in the event of an error ● Based on the shape of the graph, we can predict the problem of the device and the user From there, there are reasonable measures ● Therefore, the main system is adjusted and repaired by the OEM to better meet the demands of the user 38 CHAPTER 5: CONCLUSION & FUTURE DEVELOPMENT 5.1 Conclusion The thesis has completed all missions: ● Study and complete the fundamentals and theoretical foundation for electric vehicles (electric vehicle internal system, protocol communication, wiring diagram) ● Research and successfully build a potential IoT device working well at sending and receiving signals between electric vehicles and IoT platform ● Testing and validating results of project to ensure the quality performance of IoT device Based on the results, we have completely connected an electric motorcycle to an IoT platform for analyzing and monitoring user data By our method processes some pros and cons - Advantages: ● The signal is less delayed and correctly matches the simulated data ● from the EV simulator ● On electric vehicles, the connection protocol is quick to use and install ● Due to the usage of the user's Internet, the connection is simple and ● convenient ● The device's transmission algorithm is not incredibly complicated Data management interface that is simple to use and can support a massive number of devices at the same time - Disadvantages: The device depends a lot on the battery system, if the battery does not work, the device will also be affected Due to limited time and budget, we have not applied more for a real electric motorcycle Certainly, in the near future, the IoT for electric vehicles will be widely applied to improve our mobility and reduce traffic jams So, I hope the thesis will be a stepping stone for the development of electric motorcycles in the Vietnamese market 5.2 Future development The current research serves as the foundation and premise for effectively building and developing the issue at a higher level Improve the system in general and make it more stable in a variety of environments: ● Improving qualities of firmware and signals 39 ● Before becoming commercial, hardware optimization should be considered ● Modeling data and visualization to find the customer insights and detect issues as soon as possible 40 REFERENCES Bibliography [1] P S Preeti
