Section 1: Project Overview and Objectives

RevDash is a project aimed at developing an automotive interface for racing that collects vehicle telemetry data and displays it on a website in real-time. The primary objective was to create a hardware device that interfaces with a race vehicle's OBD/CAN Bus interface and various analog sensors to collect telemetry data, such as oil pressure, oil temperature, fuel pressure, vehicle speed, engine rpm, and more. Additionally, the device needed to collect local environmental data, including ambient temperature, GPS-based high-accuracy position data, and accelerometer readings to capture g-forces.

The data collected would then be streamed in real-time over a 5G network connection to a web portal where users, including social media followers of the driver, can view the telemetry data in real time. The project aimed to achieve an end-to-end latency of under 500 milliseconds for the data stream.

A significant challenge faced by the project was maintaining a consistent data stream, even when the connectivity was unreliable due to the nature of cellular communication in rural areas. Heitech Software Solutions, the company responsible for developing this product, built a hardware prototype and software stack to overcome these challenges and successfully meet the project's objectives.


Section 2: Hardware Development, Prototyping, and Technical Choices


To address the project's requirements, Heitech Software Solutions developed a hardware prototype named Soteria. The device was built around a programmable MX8X Cortex-A35 microcontroller single-board computer (SBC) due to its low power consumption, high processing capabilities, and compatibility with various peripherals. The SBC's built-in OBD interface used ELM327 to capture vehicle telemetry, ensuring seamless communication with the vehicle's electronic control unit (ECU) and enabling access to a wide range of sensor data.

The Soteria prototype incorporated a Quectel 5G module for network connection and data streaming to the custom-built real-time IoT platform, code-named Iris. The Quectel 5G module was chosen for its high data throughput, low latency capabilities, and compatibility with existing 4G LTE networks to maintain connectivity even in areas with limited 5G coverage.

The device ran a lightweight version of Linux as the operating system, which provided a robust, flexible, and secure environment for the application. Python was used to develop the capture code due to its simplicity, extensive library support, and compatibility with the chosen hardware components.

During the development process, the team created detailed schematics and diagrams for the hardware interface, ensuring that all necessary components were appropriately integrated. This meticulous planning facilitated efficient hardware design and rapid prototyping. To validate the device's functionality and performance, the team built a desktop hardware prototype using an OBD simulator to generate test data.

After successfully testing the desktop solution, the prototype was field-tested on a Toyota 86 race vehicle at Toronto Motorsports Park. The Soteria prototype demonstrated its effectiveness, achieving less than 100-millisecond latency end-to-end while maintaining over 98% stream integrity. This performance surpassed the project's initial objectives and validated the technical choices made during the hardware development and prototyping stages.


Section 3: Software Stack, Architecture, and Technical Choices

Heitech Software Solutions employed a combination of technologies and architectural patterns to create a performant, scalable, and reliable software stack for the RevDash project. The choice of technologies aimed to address the challenges of processing and displaying real-time telemetry data with low latency, even under varying connectivity conditions.

The software stack included the .NET framework, Microsoft Blazor, Docker, Ubuntu Linux, RabbitMQ, MySQL, MongoDB, and Redis. Each component was chosen based on its ability to contribute to the overall performance, scalability, and reliability of the solution.


Section 4: Hybrid Development Methodology and Testing

To ensure the successful development and implementation of the RevDash project, Heitech Software Solutions employed a hybrid development methodology, combining the best practices from both agile and traditional project management approaches. This strategy allowed the team to balance the flexibility and responsiveness of agile development with the structure and predictability of traditional methods.

The development process began with the creation of detailed schematics, diagrams, and graphic designs for both the hardware interface and the software architecture. This phase involved thorough planning, requirements analysis, and risk assessment, which are hallmarks of traditional project management. By doing so, the team established a solid foundation for the project, ensuring that all necessary components were identified and addressed.

Once the initial planning was complete, the team transitioned to an agile development approach, working in iterative sprints to build, test, and refine both the hardware and software components. This iterative process enabled the team to quickly identify and address any issues or challenges that arose during development, ensuring that the project stayed on track and met its objectives.

The testing process played a crucial role in the development cycle. The team utilized a range of testing methodologies, including unit testing, integration testing, and system testing to ensure the robustness and reliability of both the hardware and software components. In addition to the controlled testing environment, the team conducted field tests on a Toyota 86 race vehicle at Toronto Motorsports Park. This real-world testing allowed the team to evaluate the end-to-end performance of the solution, including latency and stream integrity, under realistic racing conditions.

Through the use of a hybrid development methodology and rigorous testing, Heitech Software Solutions successfully delivered a high-performance, reliable, and scalable solution that met the RevDash project's requirements and objectives.


Section 5: Scalability, High Availability, and Extensibility

In designing the RevDash solution, Heitech Software Solutions prioritized scalability, high availability, and extensibility to ensure the system could accommodate varying loads, maintain uptime, and support future enhancements.

1. Scalability: The system was architected to scale automatically based on the load, the number of vehicles sending data, and the number of observers receiving telemetry information. By utilizing containerization with Docker and deploying the solution on a cloud infrastructure, the team enabled the system to scale horizontally, adding or removing instances as needed to handle fluctuating demand. This approach ensured that the system could accommodate a growing user base and maintain performance during peak usage.

2. High Availability: To ensure continuous operation and minimize downtime, the team designed the system with redundancy and failover mechanisms. Critical components, such as databases and messaging brokers, were set up in clusters to provide fault tolerance. Load balancing and health checks were implemented to distribute traffic evenly among instances and automatically route around any failures. This high-availability design allowed the RevDash system to maintain data stream integrity and provide a reliable user experience.

3. Extensibility: The team implemented a robust API and microservice architecture to facilitate system extensibility. By breaking down the application into smaller, modular services, each responsible for a specific function, the team made it easier to add, modify, or replace components without affecting the overall system. The use of a well-defined API allowed for seamless integration with third-party services or applications, providing opportunities for future enhancements or collaborations.

Through careful planning and strategic technology choices, Heitech Software Solutions created a scalable, highly available, and extensible solution that not only met the immediate needs of the RevDash project but also provided a solid foundation for future growth and innovation.
