DE GUZMAN, LYNER C. and ROSARIO, JECSON P. Low Cost Wireless Communication Headset for Motorcycle Riders. An Undergraduate Design Project. Bachelor of Science in Electronics and Communications Engineering.Cavite State University, Indang, Cavite. April 2016. Adviser: Engr. Michael T. Costa
The general objective of this study was to produce a low cost wireless communication headset for motorcycle riders. Specifically, it aimed to design and construct the transceiver circuit; interface the circuit to the system; create a program
using MPLAB’s Proton IDE Compiler; and test and evaluate the system performance through pilot testing.
The design project was composed of a PIC16F628A microcontroller, and SA818-U that modulated and transmitted voice from the user. It also received and demodulated audio signals from other users. The microcontroller gave the command to the SA818-U whether to transmit or receive audio signals. Based on the button state of PTT, Volume and Channel button, the microcontroller switched the transceiver mode, volume level and channel used accordingly. A timeslot mode was also added for each device to have their own transmitting time and to avoid interference from other users. The added emergency feature was the PTT lock that permanently transmitted audio signal to other the users for them to be informed on what was happening on that particular rider.
The unit was tested first by the researchers. The project testing was done on Engineering Science (ES) Building, College of Engineering and Information Technology (CEIT), Cavite State University (CvSU), Indang, Cavite. The performance between the VOX and PTT features were tested in a noisy environment where a lot of students were present. Its responsiveness was also compared when there was no noise.The transceiver device was used by respondents and evaluated it according to certain parameters.
Based on the results of the evaluation, the project met the given objectives. The device was able to communicate with other devices based on user control. The device was also able to prove its accuracy, functionality and reliability.
Technical evaluation showed that the device was not able to function excellently when a considerable amount of obstruction was present since this distorted the signal from the FM transceiver to other transceivers.
The total cost of the design project was 14,665PHP and each wireless communication headset costed 2,933PHP.
In order for the device to be used commercially, the users must comply with the legal aspects of the National Telecommunications Commission.
