碩士 === 國立虎尾科技大學 === 光電工程系光電與材料科技碩士班 === 107 === This paper aimed to develop a new parking space allocation system for the paid parking lot. Since the transportation network around the globe is rapidly developing, the number of vehicle ownership is on the rise in each country and there is great limitation in the finite parking space available, many parking lot systems are emerging, despites their flaws. Therefore, the parking space sensor with multiple infrared sensors was developed with a low-cost model and simulated the actual parking condition, even though the detection method was not limited to the sensors described in this paper, as these sensors could be replaced with other compatible devices. This system used Holtek HT66F70A micro-controller with multiple sensors. The system would initially assign the space with the first sequential order and upload such information to the MQTT cloud-based server Wi-Fi module. Meanwhile, the green light lit up in front of the parking space of the first sequential order as an indicator for the vehicle owner. When a vehicle arrives at the entrance of a parking lot, the driver can obtain parking space information from the APP as the information is downloaded from the MQTT server, where such information is also converted into QR code to be displayed at the display window. Once the code is displayed, the APP is used to scan the code, which will further display the location of the empty space, while the entry time and the information of selected space will be recorded. The information on the empty space is provided to the user to view at any time to save the user from searching the space. When the vehicle is parked in the designated space, the information is updated and the parking space of the second sequential order is uploaded. When the parking lot is full, any vehicle leaving its parking space will immediately assign it to the next vehicle entering the parking lot to maximize the utilization rate of each parking space and the profit.
