1. Athletic Field Management System Faculty Advisors: John Lamont Ralph Patterson Tom Baird Project Client: Mary Beth Chinery Boone Area Recreation Department Group: May05- 14 http://seniord.ee.iastate.edu/may0514 The Boone Area Recreation Department is currently providing lighting to various outdoor recreational facilities without limitation. However, because of this, the department is forced to spend more money each year from rising electric rates. Another problem is that the lights are occasionally being left on after park hours, leading to citizen complaints. The solution is to provide a control unit for each lighting setup that will require users of the facilities to pay for the light they use. The unit will also provide an automatic shutoff when the park closes each night to prevent the lights from being left on. The final design will allow for local teams and clubs to use the lights without paying directly, and will include an administrative override mode to turn the lights on and off. Abstract General Problem Statement To develop a system that will control the use of lights at a variety of Boone’s park facilities by allowing patrons to pay for use of the lights with tokens and automatically shut the lights off at 11:00 PM when the park closes. Operating Environment The system must be able to operate correctly outdoors in all types of weather including: rain, snow, hail, humidity and extreme temperatures. Intended Users and Uses Persons age eight and older with a variety of educational backgrounds. Turn lights on upon deposit of token and turn them off again when time expires. Automatically shut off lights at 11:00. Provide a method for the park and recreation department to use the lights without depositing tokens. Assumptions The system will be designed in a modular fashion. A security system will be implemented for each device. Tokens will be accepted at each system location, with a central location being used for a coin to token converter. Clubs and teams will be provided an allotted and given a decided number of tokens by the recreation department for use at facilities. Limitations System must have lower power consumption to be cost effective. System must contain an administrative mode to allow the recreation department to turn on or off the lights and system at any time. System will turn off lights at 11:00 PM without exception, unless in administrative mode. A way to monitor the club and team use of machines will be provided. Must include time delay and notice to users to allow sodium lights to cool down. End Product and Deliverables Cost of parts for the devices Maintenance manual User manual Introduction Estimated Resources and Schedule Team Members: Craig Cartier (CprE) Steven Cornelius (EE) Alex McLaren (EE) Michael Schmitt (CprE) Design Objectives Must be low power consumption Must be easy to operate Must be useable in different locations Functional Requirements Accept payment for lights Provide an override key for administrative purposes Display time remaining for lights Have a way to track club and team usage Design Constraints Modular design for portability among facilities Cost effective, including low power consumption, to reduce expenses of park department Measurable Milestones Develop multiple solutions Initial design plan Final parts list and supplier Requirements Functional prototype Finalized design plan Closure Material Every year, Boone Area Recreation Department spends about 10% of its total budget on power for lighting their tennis courts and baseball diamonds. Because of this, the park is not able to spend as much money on park improvements. By creating a system that charges users for usages of these lights, Boone will be able to save money that can be used for other improvements of the park. Schedule of Events Gantt Chart *Estimated 9 systems Approach and Considerations Proposed Approach After the project definition has been completely defined, the team will come up with a variety of solutions to solve to problem. The best solution will be chosen from these based upon cost, usability, maintenance, and functionality. After the final decision of the design is made by the client, the team will begin to design the specifics of the unit. This will include programming the microcontrollers, wiring the controls, and integrating with lights Once these tasks have been completed, the units will be rigorously tested and redesigned until they meet or surpass the requirements.
