one, Overview Taxi management is the intelligent and effective management of taxis in the city using RFID technology. Due to the use of machines for identification, the identification rate is increased to avoid missed and mis-checked phenomena, and various disputes due to unclear identification are greatly reduced. This can not only improve work efficiency, but also strengthen the management of the traffic police department. Carry out effective management of urban taxis to protect the interests of the country and the people.

In modern society, taxis have become one of the public transportation means for people to travel short distances. It has a very huge market. Many unscrupulous drivers often modify their cars for their own personal interests to imitate the appearance of regular taxis. In this case, it is sometimes difficult for traffic police officers to distinguish the cloned car with the naked eye. This requires the use of technological means to manage this so that the police can quickly and accurately determine whether the car is qualified for operation or whether it is a cloned car. To a certain extent, it can also improve public security, reduce taxi robberies, or increase the detection rate when such cases occur.

Launched by Suzhou Mulan Electronic Technology Co., Ltd.The RFID vehicle long-distance identification system has been successfully used in parking lots, stations, parking lots, and containerized vehicles. After the application, the management efficiency of vehicles has been significantly improved and intelligent vehicle management has been provided. The RFID identification system fully automates the collection of vehicle entry and exit data. On the one hand, it greatly improves the image of establishing a new urban vehicle management, prevents manual operation loopholes, is conducive to data archiving, and ensures the safety and reliability of vehicle information. On the other hand, it greatly promotes This has improved the pace of automation construction in cities and government enterprises.

Excellent technical advantages, after years of experience and product accumulation, we have a first-class software and hardware team that can complete the development and production of long-distance target recognition, data transmission and other products.

The emergence of Mulan electronic technology will provide strong technical support for the application of long-distance signal recognition and data transmission, and provide the best solution for modern vehicle management.

In summary, it is necessary to solve the problem of “parking card clearance” under normal conditions, and realize “non-parking toll clearance”

two, Introduction to RFID System RFID (Radio Frequency Identification) technology has a long history and is widely used. As a high-tech company dedicated to the research and development of long-distance radio frequency identification technology, we have integrated the advantages and disadvantages of each product technology as well as the actual application and launched active electronic tags and read-write equipment. It adopts the current advanced 0.18 uM’s chip technology has substantially improved the performance of RFID. It completely solves the identification problems of long-distance, large-flow, anti-interference, ultra-low power consumption, and high-speed moving markers, and the cost is greatly reduced than before. It provides a very advanced and effective technical guarantee for the use of long-distance recognition, positioning, tracking, and data transmission of people, vehicles, and objects.

　　2.1 Generally speaking, RFID technology can be understood as a system that uses electromagnetic spectrum to transmit specific identification information in a non-contact, non-visual, and highly reliable manner.

　　RFID originates from radio communication technology. It integrates many high-techs such as modern computer technology, intelligent control, and intelligent identification, and conforms to the needs of the development of computer integrated manufacturing system applications.

　　2.2 How the RFID system works. A real RFID system should at least include a reader, electronic identification, data processing and storage equipment, and system software. The reader mainly includes a radio transceiver antenna, data communication and corresponding control circuits. The working method of RFID is: the reader emits electromagnetic waves of a certain frequency. When the identification card enters the electromagnetic field of the reader, the tag starts to move and transmits the number stored in the tag back to the reader by radio waves to identify and confirm the corresponding card number. And it can be transmitted to the PC through the serial port for data processing. If the tag has a built-in power supply, the recognition distance can be greatly increased, and its sensitivity will be greatly improved. In fact, active cards will be the mainstream in the recognition of long-distance and high-speed moving objects. Compared with IC cards, RFID technology can realize remote identification without contact. Moreover, the tag number of the ID tag is made in the tag chip when it leaves the factory, it is unique in the world, will not be repeated, and it is difficult to copy. ID tags can also be divided into two types: read-only tags and read-write tags, the latter can store equivalent information.

　　2.3 There are mainly the following key technologies: vehicle electronic tags (vehicle electronic tags), remote readers (vehicle or fixed read-write base stations), computer hosts, etc.

We adopt the method of one car and one card, and each card has a unique one in the world.ID number, the card can be placed anywhere in the car (it is recommended to be placed on the windshield of the car for easy management), and then the reader can be installed in the designated place, and a certain number of handheld PDA-type small readers can be configured. Traffic police officers can wear it with them.

As long as our long-distance tags are closely integrated with cars, the intelligent parking management system can effectively and accurately collect and record the information of vehicles entering and exiting the parking lot in a large range, and upload and process them as needed. Identify the attributes of the vehicle and drive the gates to open correctly to ensure that the access control system has the ability to efficiently release and achieve “pass without stopping.”

2.4 Schematic diagram of vehicle recognition The core technology of automatic parking lot management is the automatic recognition and automatic discrimination of vehicles. The schematic diagram is as follows:

3. The characteristics of the technical solutions provided by Suzhou Mulan Electronic Technology are very prominent, which are specifically manifested in:

3.1 Long distance: The effective reading distance between the reader and the film is 0 to 80 meters, which is suitable for most parking environments; this distance is also the technical basis for “passing customs without stopping”;

3.2 Circularly polarized antenna: The design of the reader’s receiving antenna adopts a circularly polarized antenna, which has no direction requirements for card placement;

3.3 High speed: when the vehicle-mounted card moves at a speed of 0～200 km/h, the reader can correctly identify the card signal;

3.4 Economical: The electronic label can work continuously for 5-6 years without maintenance during the period. This reduces maintenance costs for users and management, and directly improves economic benefits.
