Embodiment

[0039] Such as figure 1 As shown, the RFID-based zebra crossing recognition alarm system includes an RFID reader 1, a vehicle display alarm device 2, an external circularly polarized antenna 3, and a road buried electronic tag device 4; figure 2 As shown, the RFID reader 1 includes a control unit module 101, a radio frequency module 102, an antenna interface 103, a power supply module 104, and a serial communication module 105; image 3 As shown, the vehicle-mounted display alarm device 2 includes a power supply module two 201, a single-chip computer 202, a liquid crystal display (LCD) 203, an alarm 204, and a serial communication module two 205.

[0040] Figure 4 The external circularly polarized antenna 3 shown uses a circularly polarized directional antenna with a gain of 6dBi to reduce the uncertainty of environmental factors on the road, and the signal propagation is affected by environmental factors such as shadow fading and non-line-of-sight propagation. error. It is ins...

Abstract

The invention discloses a crosswalk identification alarm system based on RFID. The crosswalk identification alarm system based on RFID comprises a RFID reader, a vehicle-mounted display alarm device, an external circularly-polarized antenna, and a road-buried electronic label device. The RFID reader comprises a control unit module, a radio frequency module, an antenna interface, a power supply module 1, and a serial port communication module 1. The vehicle-mounted display alarm device comprises a power supply module 2, a single chip microcomputer, a display screen display screen, an alarm, and a serial port communication module 2. The road-buried electronic label device comprises an electronic label, a PC endurance board, and a silver reflective membrane. The system takes the initiative in acquiring the data of the electronic label close to the crosswalk with a RFID automatic identification method, fast acquires accurate distance between a vehicle and the crosswalk in real time, and provides a motor vehicle driver with positional warning and real-time alarm within effective distance in advance with a liquid crystal screen display and alarm manner. With visual and auditory information feedback, no matter the sight of the driver is shielded or no crosswalk advance identification is provided, the motor vehicle driver may know the effective distance between himself or herself and the crosswalk in order to timely take corresponding measures.

Description

Technical field [0001] The invention adopts radio frequency identification technology (RFID) to realize the identification of the urban road zebra crossing, quickly obtain the precise distance between the motor vehicle and the zebra crossing and real-time alarm, and belong to the field of Internet of Things and intelligent transportation. Background technique [0002] At present, my country mainly uses traffic lights, signs or diamond signs to warn the effective position of the zebra crossing in front of motor vehicles. However, due to the lack of traffic signals on the zebra crossing or the inconspicuous signs and signs, motor vehicle drivers cannot spot the zebra crossing in advance. Motor vehicles injure pedestrians and other traffic accidents near the zebra crossing, and “Chinese-style crossing the road” can easily cause motor vehicles to brake suddenly and cause rear-end collisions. Therefore, it is necessary to provide a zebra crossing identification and alarm system and cor...
