ENG13/A4 Technical Writing Introduction

Automated Parking System is an automated process that works with designation system of parking slot for every driver. It designates the optimal slot for each driver that will not cause any congestion or delay at the entrance of parking lot. During the automation, the system would designate the slot and store the data in a magnetic strip of a parking card. When the driver pushes the button to get the parking card, the screen shows the slot number and location to driver and release the card from the ticket machine. For people with disability (PWD), there is a separate button for them to press to have their own slot and parking card. The system does not work alone with the ticket machine but works with the sensor system of parking lot which detects what slots are taken already and the administration system of parking lot that overlook how the system works within whole area efficiently. The system automatically assigns the optimal slot for customer by using arrays and counters with C# and Foreach programming language. It disregards the PWD and taken slots for calculation of optimal slot. For the actual utilization of system, SM city Manila parking lot is chosen. SM city Manila has 7 floors of parking lot level and each floor has 72 slots, so it has total of 539 slots. Among those slots, 35 slots are reserved for PWDs. Numbering for the slots would be depends on the nearest column of the slots. For example, if the slots are near the column “A”, there would be slots of 10A, 11A, 12A and so on. For the non-PWD customers, the optimal slots would be calculated and designated among 72 slots per floor. For the PWD customers, the system would assign from reserved PWD slots. The Automated Parking System involves the following steps: Scanning, Selecting, Data Storing, Displaying, and Releasing. See Figure 1.1 for a flowchart of the process. Discussion The following flowchart shows the steps which is needed for the Automated Parking System to work.

Figure 1.1 Flowchart of Automated Parking System

Scanning Scanning is the primary process in which the parking system collects all the data from sensor system of parking lot and administration system. This system involves the gathering of data including receive the list on which slots are occupied from sensor system. Hence, in case where the driver parks in the wrong slot, the system would update the data for available slots for next driver and report to administration system of parking lot. If the list of available slots is received, the process is complete and ends. If the list is missing, the system reworks for it.

Selecting Selecting is the central system by which the parking slot is automatically assigned with its optimal assignment program. The process aims for finding the optimal parking slot for drivers by analyzing the nearest and easiest slots. For the PWDs, the system automatically chooses among PWD slots which are already reserved at parking lot. Once the slot is selected, data is updated for next driver to be designated by automated system.

Data Updating Data Updating is the included process upon Selecting process in which the process is followed with designation of parking slot and performed automatically. This process is vital as it provides the newly updated data for the system to select the optimal assignment continuously without error.

Data Storing

Data storing is an output process where plastic parking card is involved. In this process, selected data for each driver is stored in the magnetic stripe of parking card where it gives the driver the output from three previous process. Data like designation of parking slot, payment and time-in of customer is to be stored in this process.

Releasing Releasing is an output process in which data is received by the driver. Once the driver pushes the button to get the parking card in order to get passed through the entrance bar, the ticket machine releases the card with selected data for driver. This process tells the driver if they are now available to use the system and park inside the specific parking lot.

Displaying Displaying is final process in which the data is shown at the screen of ticket machine. Once the driver receives the parking card, the ticket machine shows the designated slot number and map to the driver for him to not get lost or get delayed in looking for the slot or shows that the parking is full. Conclusion

Automated Parking System is an automated system in which a parking slots are assigned and designated optimally and efficiently for drivers who uses parking lot. System is essentially interacting with other system like sensor and administrative system to work effectively with its purpose of removing any congestion and delays at the entrance of parking lot. During each process, precision and correct assignment is monitored by administrative system to avoid system failure. As the processes continue, the data is selected accordingly for the driver and provide the driver an ideal information as parking slot and slot map to help even with elders.
