System for vehicle-mounted RFID information data relay transmission

Abstract

The invention discloses a system for vehicle-mounted RFID information data relay transmission, which comprises a vehicle-mounted receiving end, a vehicle-mounted relay end, and a vehicle-mounted transmitting end, wherein the vehicle-mounted receiving end is used for receiving signal data transmitted by surrounding vehicle-mounted transmitting ends or signal data transmitted by road-side transmitting ends; the vehicle-mounted relay end transmits the signal data received by the vehicle-mounted receiving end to surrounding other vehicle-mounted receiving ends and road-side receiving ends in a covering mode, or carries out amplification processing on the signal data received by the vehicle-mounted receiving end and then transmits the signal data to the surrounding other vehicle-mounted receiving ends and road-side receiving ends in a covering mode; and the vehicle-mounted transmitting end transmits the vehicle driving state parameters to the surrounding other vehicle-mounted receiving ends and the vehicle-mounted relay ends in a covering mode or transmits the parameters to the road-side receiving ends in a covering mode. Through building a relay system between vehicles, the problem that the metal vehicle body blocks RFID signals can be overcome, effective reading of the driving state parameters between the vehicles can be ensured, and the purposes of intelligent early warning and driving vehicle safety control can be realized.

Description

technical field [0001] The invention belongs to the technical field of intelligent management for safe driving of vehicles, and mainly relates to a method for establishing a vehicle-mounted RFID information data relay transmission system based on RFID radio frequency and its data relay transmission technology. Background technique [0002] Radio Frequency Identification (RFID) is a wireless communication technology that can identify specific targets and read and write related data through radio signals without the need for mechanical or optical contact between the identification system and specific targets. The most important advantage of the radio frequency identification system is non-contact identification, which can read tags through snow, fog, ice, paint, dirt and harsh environments where barcodes cannot be used, and the reading speed is extremely fast, less than 100 milliseconds in most cases. The sketching capability of active RFID systems is also an important advanta...

Problems solved by technology

[0005] Since the wireless transmission signal of RFID technology cannot pass through the metal layer, the metal surface has strong reflective properties. In order to solve the problem of using RFID technology to realize the purpose of a safe and intelligent driving management system, after overcoming the occlusion of tall vehicles in the case of multiple lanes , the metal of its car body cannot realize the problem of RFID radio frequency signal transmission, which is a technical problem that must be solved
