Design Case of Intelligent Parking Management Navigation System
1. Demand background 1.1 Demand background At present, China's national economy is at an important stage of rapid development. With the sustained and rapid development of the national economy, GDP and residents' income continues to grow steadily, China's auto industry has shown explosive growth, and the scale of production and sales has remained unchanged during the 10-year period 1999-2009 The average annual growth rate of more than 20%. According to the latest statistics released by the China Automobile Association in 2009 on the production and sales of domestically produced vehicles, in 2009, China's automobile production and sales were 13.791 million and 13.6448 million, an increase of 48.30% and 46.15% year-on-year. The year-on-year growth rate of nearly 50% has also exceeded the highest blowout period in history. At present, China has become the world's largest automobile consumer. 1.2 Industry Status As people's living standards continue to improve steadily, cars as a means of transportation have gradually become an indispensable necessity in daily life. With the continuous growth of sales in the automotive industry, especially the emergence of a large number of private cars, many urban centers, Traffic and parking problems in areas such as bustling commercial areas are getting worse. Due to the shortage of parking spaces, and the blind patrol to find parking spaces, it caused congestion and disorder, resulting in many unnecessary traffic flows. The resulting serious waste of resources and time, while increasing exhaust emissions, is not conducive to the orderly, healthy and sustainable development of cities. How to effectively reduce the invalid traffic flow caused by blindly looking for parking spaces, optimize the allocation of parking resources, improve the convenience of parkers, ensure smooth traffic and regulate parking order. Reduce management costs, improve site utilization efficiency, while saving time and resources, reduce unnecessary emissions, and promote the construction of green and environmentally friendly cities. For a long period of time, the construction of parking facilities in large and medium-sized cities across the country has lagged behind the rapid growth of motor vehicles, resulting in more serious parking contradictions. The vicious circle of "difficult parking and random parking" has become a difficult and hot issue in urban traffic management. The shortage of parking berths directly causes problems such as inconvenience in travel, traffic jams, damage to greenery, destruction of the environment, and threats to safety, which affects the quality of life, increases production costs, and hinders the normal development of the social economy. If measures are not taken early, it will be detrimental to the orderly, healthy and sustainable development of the city. Therefore, the supply and demand relationship of parking must be optimized and adjusted to promote the coordinated development of the urban parking system. 1.3 Industry Analysis According to the latest survey of the number of parking spaces and cars in 16 large and medium-sized cities in China, the ratio of public parking spaces to cars is 1: 3, and some cities even reach 1: 5, which means 3 cars or 5 There is only one parking space per car, especially the ratio of commercial areas and urban tourist attractions is as high as 1:10. As of June 2009, statistics show that the 248 communities and 244 social parking lots registered in the urban area of ​​Suzhou can provide parking spaces 64760. Among them, there are only 35 solid parking garages (fields) registered in the Special Equipment Safety Supervision Office of the Municipal Quality Supervision Institute, which can provide 3393 parking spaces, accounting for only 5% of the total number of urban parking spaces. These two figures simply reflect the contradiction between "supply" and "need". However, on the issue of parking, it is by no means able to sum up the short supply. From construction to management, from resource utilization to operation and charging, the problem exists at multiple levels-this is by no means a simple problem of parking space supply. Note the following reasons: 1. Poor parking information and lack of efficiency in parking management; After the vehicle enters the parking lot, the corresponding parking space cannot be found most quickly and conveniently, and there is no corresponding intelligent instruction in the process of searching for the parking space, and the unnecessary search in the process of searching for the parking space causes unnecessary traffic. Waste time and resources of car owners. The inefficient use of existing parking spaces is also an important factor affecting static parking. It is also a problem in front of managers to provide an effective method to improve the utilization rate of existing parking space resources, and to stably and efficiently convey parking space information in various parking lots to the driver. The intelligent parking management system will provide free parking space information in real time through the parking space detection technology and provide navigation functions to effectively solve the trouble of finding parking spaces. 2. The management is chaotic, the charging standards are different, and it is easy to cause disputes; At present, most parking lots adopt the personnel charging method. In the charging process, the charging factors such as parking time and vehicle type are not clear, which is likely to cause disputes. At the same time, the accounts are unclear, and there is no way to avoid fraud and stolen fees. The intelligent parking management system will automatically register vehicle entry and departure times, automatically charge and display, and use wireless voice prompts and other functions to increase transparency and credibility. At the same time, reports can be automatically generated according to the time period, so that the charging situation is clear and correct. 2. Products and functions 2.1 Product introduction In the intelligent parking lot management system, we are the first to propose an intelligent parking lot management system based on the combination of Wi-Fi + RFID + infrared sensing technologies, mainly to achieve three major functional requirements: intelligent vehicle navigation, card fee collection, and parking Management and other functions. To meet the urgent needs of modern parking areas. The system enables system design from the perspective of improving humanization and intelligence. Make the whole parking process highly connected, and realize the intelligent storage, exit and charging of vehicles. 2.2 Product function and description In order to achieve the above goals, the following analysis is made on the design of the parking system: The intelligent parking system is a system with autonomous power. The goal of the system is to realize the wireless communication between the vehicle and the garage management system after entering the garage area. No one will automatically drive to the parking place designated by the garage management system. When the vehicle owner needs to extract the vehicle, only the parking lot management system operates the vehicle, the vehicle will automatically drive to the designated exit. The design of the system requires as few guiding signs as possible to the parking lot, so as to minimize the layout cost of the parking lot. First of all, I first virtualized a parking lot, as shown in Figure 3.1. When the vehicle enters, swipe the card, confirm the identity, after the information is correct, the brake lever opens, the vehicle enters the parking lot, the LED navigation screen can display the parking space of the entire parking lot, automatically navigate the vehicle direction, when the owner parks properly, the system automatically recognizes The parking space of the vehicle is returned to the server, and the navigation record is refreshed at the same time. When the owner drives away, the system automatically calculates the parking time and calculates the amount. 2.3 Design principles The system adopted in this system and the composition of the system comply with the following principles: Normative This system complies with relevant national standards and industry standards during the design process. Practicality The system has the ability and level to complete the functions required in the project.
