Question: Discuss About The Problems Experienced During Day To Day Lives? Answer: Introduction This paper is aimed at discussing Internet of Things and its applications in recent times to solve common problems experienced during day to day lives. Internet Of Things or as it is commonly referred to as IOT is the inter-networking of a range of physical devices which are embedded with various electronic devices, sensors, software and have network connectivity capability to enable them to communicate with each other by sending and receiving information. The main objective of IOT is connectivity of devices to enable them to communicate and relay information between themselves. The paper narrows the discussion to one case study which is Automated Car Parking with Empty Slot Detection. Problem definition Cars are becoming an essential part of our lives with a lot of people choosing cars to travel from place to place while doing their different errands. Because of high use of cars by many people within a city parking of the cars has become a major problem where by it is not easy for someone to find a parking slot to park their cars as they go on with their errands. A rising technology management which is being termed as Smart Cities is on the rise where by cities are incorporating technology specifically IOT to solve problems like finding empty slots in a certain area of a city. The Automated Car Parking with Empty Slot detection is the one of the IOT projects that is being used and is still being developed and improved to be used in smart cities. Solution To solve the problem of finding an empty slot the Automatic Car Parking with Empty Slot Detection is a very useful project. The project has been designed to work by enabling users to find an empty slot around the area they are driving at. When the user indicates that they want to park the vehicle, the system starts searching for the nearest empty slot. Parking slots have sensors which are able to send and receive data. So when a broadcast is sent from the car looking for car space it goes to all the sensors in every parking slot near the area. The slot which is empty responds and the car is directed to that specific parking slot. This project is able to work because there is communication of phychology devices to identify which parking slot is not occupied (Automated Parking System, 2015). The following diagram shows a conceptual model of how the system works. Figure 1: Cited From: (Aqraa and Jaber, n.d) page 4 The diagram above demonstrates how the system works. The system unit is the system contained by every paring slot. This unit is installed to detect if there is a car in that parking slot and to relay information to the coordinator which then relays to the server. The coordinator contains an Ethernet module which is ensures interconnectivity with the server so that the user is able to issue a parking request and the server instructs the coordinator to look for an empty slot. For the system unit to detect is there is a car in the parking slot, it uses ultrasonic sensors. The ultrasonic sensors detect any physical objects in the parking slot resembling a vehicle. Thus to avoid miscalculation the sensors are configured to sense a stationary car and the distance of the car from the sensors. This helps eliminate the problem of the sensors detecting a passing car when a parking request is sent. Thus, for the parking slot to be empty, the sensors must show that the car is stationary and that the distance between the sensors and the car indicates that the car is parked (Automated Parking System, 2015). Figure 2: Cited From: (Aqraa and Jaber, n.d) page 8 When using more than one ultrasonic sensor the following issues must be highly considered. Collision of between the sensors and interference between the sensors plays a crucial role to ensure that the two sensors will not affect each other. The reading of the sensors does not happen simultaneously as a sensor is read once at a time. Thus the timing between when the first sensor reads and when the second sensor reads is very crucial. After reading and confirming that the slot is empty information is relayed to the coordinator then to the server and back to the mobile phone of the user who requested to find an empty parking slot. The user can then drive the car to the empty using the directions provided. After the vehicle is parked, then the user can check out by paying for the time the car has been parked there. The system unit has an LCD and a keypad where they are supposed to enter their payment details and the checkout is done. Pros of the system The system has many advantages if implemented to enhance the smart cities project. The following are the pros of the system. The system makes it very easy for drivers to find empty parking slots by just sending a parking request. The system itself is responsible for looking for an empty slot by communicating with the coordinator unit which in turn coordinates with the system units installed in every parking slot and then determining which parking slot is empty. The system makes it very easy to pay for parking because it automatically calculates the time the car has been in the parking and the driver can pay for the parking using a unit just right there in the parking slot. Problems of the system The following are the possible problems with the system. The ultrasonic sensors are not 100 % accurate because they can be affected by external physical conditions thus the system unit might not be very efficient and might provide inaccurate information to the coordinator units. However, this is not a bigger problem as compared to using IR sensors which are very inefficient during daytime (Aqraa and Jaber, n.d). The project by itself is very costly because mainly of the system units installed in every parking slot. Conclusion The automated Car Parking System with Empty Slot Detection is a very viable project to implement in any city wishing to achieve the smart city status. Although it is costly to implement, if implemented it can bring about more benefits thus justifying the cost of the project. References Aqraa, G., Jaber, M. (n.d.). Smart Parking System .
