Design of Taxi Identification System Based on RFID Technology

1.1 Overall solution

The scheme design uses the spatial coupling of RFID radio frequency signals to realize the contactless information transmission, and realizes the inspection purpose through the transmitted information identification. Its research and development and promotion include the following three main contents. (1) Develop and develop RFID chips for vehicles, and test the vehicles in a small range to ensure the reliability and safety of the hardware. (2) Combine the taxi management system of the Traffic Management Bureau of the Ministry of Public Security to dock the software part of the chip to provide data guarantee for anti-counterfeiting, inspection and management in practical applications. (3) Debugging and optimizing RFID chips for mass production and promotion. The scheme utilizes the electronic tag characteristics and digital anti-counterfeiting technology of RFID technology to maximize the uniqueness, non-destructibility and confidentiality of passenger taxi information in large cities, and realizes non-stop, long-distance automatic identification of running vehicles, and reduces The anti-counterfeiting cost of vehicle licenses and cards has improved the informationization level of public transportation management in large and medium-sized cities.

1.2 Key technologies of RFID

In the implementation process of the overall identification system, the application of RFID technology has become the key to the successful implementation of the system.

(1) RFID application architecture. Since the RFID chip plays multiple tasks of carrying, connecting, transmitting, receiving, etc. in the system, it studies the interface technology and service functions of various hardware, software and data in the taxi identification system, and coordinates the relationship between the various parts of the system. Will be the primary consideration. Among them, the design specifications of the RFID chip will meet the ISO 18000-6 Type B/C technical standard, its working frequency is 860 ~ 960 MHz, the storage capacity is 256 ~ 204 8 b, and the working distance is not less than 5 m.

(2) RFID system integration and data management. In the system, the RFID chip installed on the taxi will record all personal information and operation information such as the driver's vehicle. Therefore, RFID and wireless communication, sensor network, information security and other integrated technologies, RFID application system middleware technology, and the organization, storage, management, exchange, distribution, data processing and cross-platform computing technology of massive RFID information resources will Ensure the use of vehicle RFID chips.

(3) RFID public service system. According to the data resources of the taxi operation provided by the Traffic Management Bureau of the Ministry of Public Security, the system can realize all the data service information of the vehicle, including information, services such as authentication, registration, coding management, multi-coding system mapping, code analysis, retrieval and tracking. The path ensures the effectiveness and security of the system.

(4) RFID detection technology and influencing factors. In the research and development stage of the system, the in-vehicle RFID chip and related products physical characteristics and performance consistency detection technology and specifications, label and readers air interface consistency detection technology, and specifications, system solutions comprehensive detection technology and specifications Etc., will become the necessary guarantee for the smooth implementation of the system. These include the effects of different dielectric properties, mechanical properties and other factors on the performance of RFID tags, and the impact of complex control environments (electromagnetic, high temperature, vibration, etc.) on RFID readers.

The realization of the RFID identification system has greatly enhanced the market competitiveness of the RFID technology industry, and its industrialization is imperative. The following implementation steps should be taken mainly.

(1) Cultivate the market, use the application as the guide, accelerate the realization of the industrialization of the research and development of key technologies of RFID through the demonstration and promotion of typical industry applications, and form a scale development.

(2) Further promote industrial upgrading, improve competitiveness, and realize the development of RFID product design from general to professional. The production equipment of the product is continuously improved from primary to advanced, improving product consistency and yield, and accelerating the RFID industry chain. The overall level.

(3) Actively create a good development environment, strengthen policy support, adhere to the technological development path of combining independent innovation, integrated innovation and introduction of innovation, and strive to cultivate independent design, development and manufacturing capabilities.

(4) Further improve the industrial policy, actively introduce new financing channels and models, build an RFID industry base, realize the convergence of technology and industry, and promote the formation and development of the RFID industry chain.

(5) Establish a product certification system, focus on promoting core technology products with independent intellectual property rights, create a good market order, and promote the sustainable and healthy development of the RFID industry.

(6) Strengthen the construction of public service systems such as RFID technology product testing platforms, and improve the “incubation” transformation capability of technology research and development results.

(7) Pay attention to the standardization of RFID products and formulate a series of standards to adapt to the development of China's industry.

Based on RFID technology, this paper constructs the overall framework of taxi identification system in large and medium cities, and gives the necessity and possibility of its promotion. The research proves that the design framework can adapt well to the current domestic communication means and capabilities, and can support the system scale expansion and function expansion. In addition, the system can also optimize the management strategy to improve the response speed, system efficiency and stability of the whole system. Sex.
