The taxi remote electronic identification system adopts the most advanced RFID (radio frequency identification) technology and software technology in China to build a comprehensive platform suitable for urban taxi management. The system includes two aspects of comprehensive business processing and inspection. Through the establishment of a remote electronic identification system for taxis, the installation of “dual-frequency vehicle identification cards” for urban taxis, and the deployment of on-board and hand-held inspection equipment can efficiently identify and accurately combat various illegal operating vehicles, and regulate the operation of legal taxis Behavior, and effectively maintain the normal order of the urban passenger transport market. Relying on this system, it can also implement dynamic monitoring of taxi companies, and grasp the operating conditions of taxi companies. Especially for abnormal situations such as frequent replenishment of taxi cards and driver changes, the management department can promptly find out and investigate and deal with it to prevent large-scale Strikes and other chain reactions.
The system is mainly composed of vehicle identification card, vehicle inspection equipment, handheld inspection system, fixed inspection equipment and taxi electronic identification management system. Through this three-dimensional inspection method, law enforcement officers can accurately determine the validity of the certificate and the legitimacy of the vehicle in the first time, reducing the inspection time and unnecessary disputes. At the same time, it can also assess the law enforcement index of law enforcement officers to avoid inaction.
n Dual-frequency technology (patent) for vehicle identification card
The vehicle identification card is the only legal identification affixed to operating taxis. The inspection system will use it to read vehicle information from a long distance to determine the legitimacy of the vehicle.
This dual-frequency technology mode avoids the inherent shortcomings of single-frequency label management in the past, and not only realizes long-distance regional multi-vehicle recognition, but also achieves the purpose of short-distance targeted bicycle management. Aiming at the analysis of the management mode of the domestic taxi industry, a dual-frequency reading and writing method combining active 2.45GHz and passive 920-925MHz is adopted. Performance advantages of dual-frequency electronic tags:
n Equipped with electronic identification technology of disassembly state (patent)
The vehicle identification card is equipped with the electronic identification technology of the disassembly state, and actively transmits the disassembly signal. And can be read. Even if the disassembled chip is repaired and restored with exquisite circuits, the system can still determine that the card is an illegal card and can track the disassembled label. This technology effectively distinguishes whether the identification card is artificially damaged, and whether it is malicious substitution or application by criminals.
n With high performance and high complementarity
The passive tag of the vehicle identification card used in this project has a service life of more than 10 years; the battery life of the active tag can reach more than 8 years. And when the battery of the active device is out of power, the passive device can still work, and the electronic tag can continue to function. So as to ensure the quality of the electronic label itself.
n Dealing with disputed vehicles such as malicious card replacement
It is normal to replace the card due to loss or damage. However, some illegal operators maliciously supplemented their cards in order to obtain a legal “talisman” for the licensed vehicles. In this regard, after 6 years of research, Huibang Technology has formulated a complete set of effective solutions. The realization of intelligent online analysis mechanism is mainly through the three steps of “data warehousing-online analysis-data mining” to analyze the vehicle identification card change data and audit data of this project, and through data association, cluster analysis, classification, prediction, and time series mode And deviation analysis.
n Smart IoT
With the gradual improvement and construction of the project, GPS (Global Positioning System), GIS (Geographic Information System) and intelligent road guidance systems will be gradually introduced to realize the following related IoT functions.
1. Decision support system for emergencies
The GIS system of the command center will monitor every taxi with GPS in real time. When a large number of taxis gather, the GIS system will automatically send instructions to the vehicle-mounted inspection vehicles. The in-vehicle inspection system will notify the inspectors through voice prompts, and automatically design the best driving route to reach the location of the incident as quickly as possible. At the same time, the remote electronic identification system can quickly extract the crowded vehicle information, vehicle owner information and company information, and can provide information decision support at the first time.
2. Intelligent road guidance system
This system uses urban taxis and buses to monitor the road conditions in real time, which can realize real-time and scientific guidance. Utilizing the driving characteristics of “ubiquitous” taxis and “fixed route” buses, electronic dredging devices such as road condition LED displays can be used to monitor and broadcast road condition information in real time, prompting drivers to avoid peak sections and construction sections, which is reasonable Plan road emergency traffic conditions and rationally optimize diversion to solve road congestion.
3. Intelligent traffic signal control system
After analyzing the long-term accumulated monitoring data, real-time monitoring of the running speed and driving path of taxis and buses in the city can accurately grasp the overall traffic flow and conditions of the city, and realize the function of intelligent control of traffic signals.
Therefore, the traffic signal lights at a certain intersection can be controlled to realize the bus advance mechanism; the traffic signal lights in a certain period of time can be controlled to automatically adjust the mechanism according to the traffic flow on the road; the green light traffic mechanism of the main road can be realized during the idle time of the road, and so on. These timely and accurate road conditions information will surely provide convenience for urban traffic management.
