Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

RDID is a simple wireless system that includes an RFID transmitting device (or electronic tag) and an RFID receiving device (or reader). The RFID transmitter (or electronic tag) is divided into an active type and a passive type, and the active type tag has a longer reading distance and a larger memory capacity, so the transmitter of the present invention is active, i.e. the RFID transmitter has a power module to provide the energy required by the operation for each module.

Fig. 1 shows a system block diagram of the present invention. The system of the utility model comprises an RFID transmitting device 10, an RFID receiving device 20, a traffic control center 40 and an in-vehicle loudspeaker 30. The RFID transmitting device 10 installed on the road warning board establishes wireless communication with the traffic control center 40, the wireless communication is one of GSM, GPRS, 3G, WIFI and RJ45, the RFID transmitting device receives traffic warning information from the traffic control center 40 through the wireless communication, the traffic warning information comprises front road construction, closing of a highway due to heavy fog, traffic accidents occurring in which lane and the like, the RFID transmitting device 10 sends the warning information to the RFID receiving device 20 in the passing vehicle, the RFID receiving device 20 in the vehicle synthesizes the traffic warning information into voice information through an intelligent voice recognition technology, and the synthesized voice information is output to the speaker 30 in the vehicle for voice broadcasting.

Fig. 2 shows an apparatus structure diagram of the RFID transmitter 10 and the RFID receiver 20 in the system of the present invention. The RFID transmitter 10 mounted on the highway warning board includes a CPU11, a communication module 12, an RFID antenna module 13, and a power module 14 connected to the CPU11, respectively. The RFID transmitting device 10 establishes wireless communication with the traffic control center 40 through the communication module 12 to receive the traffic warning information from the traffic control center 40; the RFID antenna module 13 is configured to transmit the received traffic warning information to an RFID receiving device 20 installed in the vehicle. The RFID receiving device 20 includes a CPU21, an RFID antenna module 22, a voice synthesis module 23, a power supply module 25, which are connected to the CPU21, respectively, and an audio module 24 connected to the voice synthesis module 23. The RFID receiving device 20 receives the traffic warning information sent by the RFID transmitting device 10 through the RFID antenna module 22, synthesizes the traffic warning information into voice information through the voice synthesis module 23, and outputs the synthesized voice information to the in-vehicle speaker 30 electrically connected to the audio module 24 through the audio module 24 for voice broadcasting.
