Jaeho Shin | Jshin79 Beixi Zhang | Beixiz2 Danni Yang | dyang46 The first measure of campus dorm security is the entrance where the students are required to swipe their i-card to enter the building. The student is not to allow any strangers to follow them in through the unlocked door, however, these days the rule is loosely enforced and have caused a series of theft to occur on campus. The idea was vaguely discussed in the previous post, this project proposal aims to answer the unanswered questions with the additional details . https://courses.engr.illinois.edu/ece445/pace/view-topic.asp?id=27045 The idea around this project is that student before entering the door will give the number of people that will enter the door following the swipe of an i-card. Once the input is given it will trigger the people counting mechanism attached on the PCB board (made up of mmWave sensor, DSP, and MCU) to make sure that the count inputted is being respected. In the case where the count is not respected the algorithm will be set to raise the flag to light up the LED lights to alert the front desk. In addition to it, we will implement the LED counters to give them the needed information to analyze the situation (number given as input and the number of people who have entered the building following the key swipe). The biggest challenge in this project is making sure that the mmWave sensor accurately detects the people in the small clustered environment as they pass through the campus dorm door. We chose to work with the mmWave sensor because it has ability to distinguish nearby objects from each other and it has high resolution. A mmWave system that resolves distances to wavelength has accuracy in the mm range at 76-81GHz(with a corresponding wavelength of about 4 mm),so it has ability to detect movements that are as small as a fraction of a millimeter. Meaning that mmWave will be able to detect people closely clustered. We will have to design the PCB board to consist of the DSP and MCU for evaluating the image working with the mmWave sensor. This is a good project for the senior design because it incorporates both software and hardware designs to implement. We will be using the input from the user on how many people to enter through the door and use the counting mechanism implemented with the mmWave sensor to detect that the count per student swipe is being respected, alert otherwise. The project itself will be a standalone will not be attached to the actual locking mechanism of campus dorm door nor student's i-card reading system but it will have a mock signal from either the USB keyboard or the keypad attached to the PCB to trigger the above mentioned algorithm and mechanism to show the potential of adding this project on top of currently existing campus dorm security system to enhance the system itself. Answers to previously unanswered questions: 1. How will it tell apart people coming in or out? -mmWave sensor is capable of keeping track of object's velocity, angle, and position at the time of detection (depending on software implementation) and keeps track of it. Therefore using the directions, we will be able to tell apart people going in or out. Also sensor should be activated only when given the input to start counting. 2.How will it tell apart people clustered together in the narrow door environment? -As long as people are couple centimeters apart the sensor will be able to differentiate the objects. 3.Competitions? How is this project unique? -While there are several different implementation of people counting mechanism that is being used for the everyday business purpose but during our research we were unable to come across a mechanism where they have to respect the number given in the input to make sure that the count is being respected. Our project is focused on enforcing the rule within our campus as well as improving the quality of life in secure environments where all staffs are to ID themselves in.
