Problems solved by technology
[0004] However, the traditional road sign technology is likely to cause unclear identification of signs at night or in rainy days, resulting in traffic accidents. In addition, the labeling of signs is often caused by errors and slow updates due to perceived factors
Newer technologies may use magnetic technology, barcode technology or optical recognition technology for automatic road sign recognition. The above-mentioned technologies have certain difficulties in operability and large-scale application. The direction of marking automation transformation

Embodiment Construction
[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0018] This radio frequency electronic tag road sign recognition playback system is shown in Figure 1, Figure 2 and Figure 3. Figure 1 illustrates the schematic diagram of the system. The vehicle numbered 3 is a set vehicle, which is read and written by the antenna 4 and the reading and writing device 5. Three radio frequency electronic tag road signs 1 on the road, or radio frequency electronic tag road signs 1 hanging on the pole, the rear car 2 is a vehicle that needs to read information, and it passes through the antenna 4 placed in front of the car or under the vehicle body Read the information of the radio frequency electronic tag, and effectively play it through the playback display device 6 in the car; the electronic tag writer is connected with the CPU in Fig. The voice bank and the Chinese character voice bank are connected; in Figure 3, the a...

This invention relates to a system for identifying and playing RF electronic label road marks including an RF electronic label as the carrier for storing information of road marks or lines, an electronic label fetcher with antenna. When a car taking the car carried road mark identifying device passes through the road placing electronic road marks or mark lines, the road read-write device with antenna and the RF electronic label are in a certain distance, the RF electronic label will receive the radio signals emitted by the antenna, which drives related road marks or line information back to the antenna, the read-write device identifies and reads said returned-back signal to be output via an output device. The system can set and fetch road traffic marks by way of electronic labels and tells drivers the information of the label or mark lines by ear or eye.
Description
technical field [0001] The invention relates to the field of electronic information, and relates to a radio frequency electronic label road sign identification and playback system that can automatically identify and use voice to play or display road traffic signs, road traffic marking lines and road condition information. Background technique [0002] Traditional road signs are displayed on poles on the side of the road, and are displayed on the road in the form of characters or symbols such as "speed limit", "stop" and other signs, "pedestrian crosswalk" signs and "pedestrian attention" signs. A vehicle driver then slows down or stops or reacts in other ways after visually confirming this road sign. Reflect the signs into his or her driving with this car control. [0003] In the traditional road sign sensing system, the road conditions that change at any time are guided by means such as luminous sign boards. In addition, people are still trying to use electromagnetic wave...
