DeliverablesListed here are the system deliverables for Project Swift Fox. Table 1. Swift Fox Deliverables.
Power Supply/Regulator:The 12 volt power supply from the vehicles battery will be used and converted to a 5 volt signal for the system.Digital Components:Digital components consist of the microcontroller, oscillator, ADC, and serial EEPROM. Analog Front End:This will consist of the operational amplifier circuit for conditioning the signal from the accelerometer to the ADC. Container:The container will hold and protect the device from the outside environment. It will consist of a main container for the PCB and a smaller one for the accelerometer Printed Circuit Board:A printed circuit board will be designed using IVEX software on the UP engineering computers. It will be ordered from PCB express and will have pads to connect components and peripherals. Menu System/Display/Keypad:A main embedded control program will need to be designed to act as a terminal, which will accept keypad button presses and output appropriate information to the display. This main terminal program is the coordinates all other drivers in the system. The program will also allow a computer to interact with the automotive performance monitor, send simple commands to retrieve data and remotely program the monitor.
I/O Driver:A driver will need to be designed to transmit and receive data over the RS232 port. Program Microcontroller and components:Microcontroller will need to be programmed to interface with the other components.
This section outlines the development process of project Swift Fox. Listed within are the general approach we will use, assumptions that have been made, the project milestones, risks, the project schedule, and contingencies for the above mentioned risks. General ApproachTo start the design of Project Swift Fox, we will first do some tests to become familiar with the challenges we are up against. We are testing the accelerometer, the voltage from an automobile power supply, and looking at the logic signal coming from a vehicle’s distributor cap (to obtain engine speed). After this process is completed, we will begin the design of the project. The digital components, user interface and PCB will be designed in tandem with the analog front end and power supply. Once this is done, the whole project will be combined for the final design along with designing the container around it. Once the design is completed and approved, we will begin with construction. We will order the PCB and start programming the microcontroller and the various I/O programs. After they are working, they will be attached to the device along with the analog front end, sensors, power supply, and other components. Next, the container will be constructed and the system will be tested and debugged until it is running properly. Design will span over the fall semester and the construction, programming, and testing will occur from winter break into the 1st half of spring semester. During the process we will also be focusing and meeting deadlines for all the required documentation including the Founder’s Day presentation and the final report.
AssumptionsThe following are assumptions that we have made about the components and environment of project Swift Fox. All specs from the data sheets for the various components are correct. Formula SAE car will be completed and compatible with the device Power source from vehicle will produce an unstable voltage that will need to be regulated MilestonesListed and discussed below are the milestones of Project Swift Fox Table 2. Key Swift Fox milestones.
Thus far, we have been making good progress on our milestones. However, we need to get the ball rolling on the design portion of the plan. As Table 2 shows, we are approaching crunch time for this semester and need to start design immediately. All the subsystems of the device need to be finished by the end of the month to be integrated together for the final design and the design release. We are aiming to have the programming done and construction well underway by the end of winter vacation. Once construction is done, we should have plenty of time to test this project on vehicles and iron out any hitches that might come along. The goal is to have the project easily ready for the prototype release and approval and allow us plenty of time to complete the final report and founder’s day presentations.
RisksThe following section lists and describes the risks associated with Project Swift Fox. Risks range from a medium severity to a low severity. We expect no high severity risks. Severity corresponds to the probability of the risk and its affect on project completion. The contingency section in this chapter highlights how we will deal with a risk if it becomes a reality.
