Overview Background Deliverables Restrictions Principles of Operation Development Approach System Block Diagram Marketing Q & A

Background Customers waiting in line Avoid wasting time – Avoid waiting in line – Profitable to businesses Less waiting time = more happy customers = more business = more money Consistent customer flow

Deliverables A robust sensor system Intelligent algorithms computing waiting time User friendly web site ECS Portal Advertising Cost effective system Technical Manual Feasible future implementation

Special Restriction The PQS system can only work in the presence of an Wireless Internet connection. The sensing area should be narrow enough so that only one patron will get counted at a time. Different settings require different setups; i.e. it’s not generic Any further restrictions will be considered upon evaluation results.

Principle of Operation Simple setup – One transmitter and two receivers The PQS project relies heavily on the accuracy of the sensors The controller board stores the current count for the number of customers at our clients location Determine Congestion Level

Principle of Operation Apache server hosting a multi-thread java server and Web services A real time updated graph – every 5 minutes interval Advance Algorithms will be used to calculate wait time Data transmitted via WIFI network

Development Approach Implement and install a PQS Implement Apache Server Develop a eye-catching Web site Implement advanced algorithms Advertise System to Public Measure Performance Refine Sensor Arrangement

Design Constraints Human Nature Strict Queue – Users entering through exits Lumped Queue – Requires Smart Controller Web Interface – Database management – Security

Input/ Output Number people in line sensed by the infrared sensors Reset counter by the users Number of people on the line and approximation of wait time showing on PQS Webpage. Acceptance test - The system will be installed fully functional at Marcus Café. Its performance will be tracked over time and compared data to observe congestion.
